2.6.8-long-format changelogSummary of changes from v2.6.7 to v2.6.8 ============================================ <len.brown@intel.com> Kconfig typo fix from Jochen Voss <len.brown@intel.com> [ACPI] PCI IRQ update (Bjorn Helgaas) http://bugme.osdl.org/show_bug.cgi?id=2574 mp_parse_prt() and iosapic_parse_prt() used to allocate all IRQs, whether devices needed them or not. Some devices failed because the this method enabled unused PCI Interrupt Link Devices, which disrupted active link devices. Now the PRT knowledge is pulled out of the arch code and the IRQ allocation and IO-APIC programming is done by pci_enable_device(). This is also a step toward allowing the addition of new root bridges and PRTs at run-time. The architecture supplies unsigned int acpi_register_gsi(u32 gsi, int edge_level, int active_high_low) which is called by acpi_pci_irq_enable(). ACPI supplies all the information from the PRT, and the arch sets up the routing and returns the IRQ it allocated. <rl@hellgate.ch> [PATCH] Nuke HAS_IP_COPYSUM for net drivers Entirely untested, but Obviously Correct(TM). HAS_IP_COPYSUM has been utterly meaningless for a long time. <herbert@gondor.apana.org.au> [NETDRV #1] Ifdef builtin-only probe in ISA/MCA drivers Here is the bit which conditionalises the builtin-only probe functions. <herbert@gondor.apana.org.au> [NETDRV #2] Use driver-specific name for resources Here is the next part which uses a driver-specific name instead of dev->name for resource allocations prior to netdev registration. It also changes printks that are in direct response to errors in resource allocations. <hch@lst.de> [PATCH] move scsi debugging helpers and give them sane names - give the constants.c prettyprinting helpers proper scsi_ prefixed names (and keep compat versions for 2.6.x) - move them to include/scsi/scsi_dbg.h so now really only legacy stuff is left in drivers/scsi/scsi.h Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com> <jejb@mulgrave.(none)> SCSI: slave_detach -> slave_destory comment fix From: Guennadi Liakhovetski <g.liakhovetski@gmx.de> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com> <jejb@mulgrave.(none)> Convert tmcscsim to new probing interfaces From: Guennadi Liakhovetski <g.liakhovetski@gmx.de> Update the driver to use the new pci, scsi and module interfaces. Modified with feedback from hch Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com> <brking@us.ibm.com> [PATCH] ipr scsi busy io hang Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com> <brking@us.ibm.com> [PATCH] ipr duplicate ioa reset fix This patch closes a window where if a device had a cancel all outstanding as a result of a check condition and the adapter was reset for some reason, a request sense would still be issued, which would end up timing out and issuing an additional adapter reset. It could also result in a leak of command blocks, depending on when it timed out. Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com> <brking@us.ibm.com> [PATCH] ipr driver version 2.0.8 Bump driver version Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com> <davej@redhat.com> [PATCH] USB / SCSI multi-card reader whitelist updates. For more info see Red Hat bugzilla entries #85851 and #124048 Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com> <jejb@mulgrave.(none)> MPT Fusion driver 3.01.07 update From: "Moore, Eric Dean" <Emoore@lsil.com> Clean up backword compatibility with 2.4 kernel and older. Patch provided by Christoph Hellwig<hch@lst.de,hch@infradead.org> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com> <michaelc@cs.wisc.edu> [PATCH] SCSI: remove extra queue unplug calls blk_insert_request will do the right thing and either unplug the queue or call the request_fn, so users of scsi_do_req do not need to call generic_unplug_device themselves. The attached patch just removes that call from scsi_lib.c and the sg driver after they do a scsi_do_req.

Specifically the megaraid3 series devices used an intel pci ID (8086:1960) which is the generic i960 identifier not their own. The code to do this in 2.4 worked for almost all cases, but even that code has mysteriously vanished in 2.6 meaning the megaraid driver trashes stuff like promise i2o cards and compaq management cards. The following patch puts back the 2.4 stuff + one additional check so that the driver isn't quite as rude as it was before.

Should be FORCELUN not SPARSELUN ? Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com> <g.liakhovetski@gmx.de> [PATCH] tmscsim: Update version after "new API" The "API-update" patch, just approved by Christoph deserves a new version.

As a side benefit, choose_address() and release_address() can now become static. The other two can't, because they have to be exported for use by HCD's when registering/unregistering root hubs. Some other features of the patch: The usb_snddefctrl() and usb_rcvdefctrl() macros have been removed, since only one of them was used and only in one spot. The comment about configuration choice needing to interact with hub power budgeting has been moved in accordance with David's wish. usb_new_device() checks to make sure a configuration could be chosen and logs a warning if no choice was made. Following Linus's preference, the #ifdef preprocessor stuff has been removed from around the calls the show_string routine. It is now defined as a non-inline routine when debugging is enabled and as an inline no-op otherwise (the compiler will optimize away the useless tests).

This allows for more consolidated and cleaner definition of and management of attributes. - Add struct class::class_dev_attrs to do something similarly for class devices. Each class device that is registered with the class gets that set of attributes added for them, and subsequently removed when the device is unregistered. Each array depends on a terminating attribute with a NULL name. Hint: use the new __ATTR_NULL macro to terminate it. <greg@kroah.com> Driver Model: More cleanup of silly scsi use of the *ATTR macros...

It wakes up threads waiting for an endpoint to be disabled in the oddball case where interrupts aren't working. (This should have been in a previous patch but I missed it.)

Right now the driver only does so if the status happens to be CONNECTED at one particular instant. However, the whole point of debouncing is that the connection is subject to transient interruptions until it has stabilized; hence deciding whether to debounce based on a single initial test defeats the entire purpose. There are some additional smaller changes that go along with the major one: Comments added to hub_port_connect_change() detailing the conditions under which it will be called. Don't clear the port's connect-changed feature if it wasn't set. Skip debouncing if there wasn't a physical connection change but only a logical port-enable change (or a firmware-download- induced device morph -- not yet implemented). Clear all the hub status change indicators in hub_events() before handling a connect change. This will reduce syslog clutter from status change bits that remain set while khubd is busy taking care of a new device. The patch includes no changes to the debounce routine itself. Please apply.

The only behavioral change is that it actually requests the port status at the start, rather than assuming the status is not CONNECTED. Changes include: Vastly improved comments that are now unambiguous and accurately descriptive of the code. Local variables changed to more sensible names. The stability period is now reported in milliseconds rather than a meaningless poll count. The sleep interval is moved from the start of the loop to the end, so that the first time through we read the port status immediately. If the connection has not stabilized after the total timeout expires, -ETIMEDOUT is returned rather than whatever the current connect status happens to be. If the connection does stabilize then the port status is returned so that hub_port_connect_change() will have an up-to-date value for the status rather than relying on the pre-debounce value. The changes I wanted to make but other people were worried about are included as comments. A later (small) patch will uncomment them for testing. Signed-off-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Greg Kroah-Hartman <greg@kroah.com> <stern@rowland.harvard.edu> [PATCH] USB: Genuine changes to hub_port_debounce() This patch includes the algorithmic changes I would like to see in hub_port_debounce(). They are: Increase the total timeout period from 400 ms to 1500 ms. Check the port's connect-changed status during the polling loop. Return as soon as the connection has been stable for the required time, even if it has been stably _dis_-connected. (The current code waits for the full timeout period if there isn't a connection.) In previous emails I have responded to all the concerns raised by others about these changes, and I can't imagine how they could cause any trouble. Increasing the total timeout won't affect people with properly functioning hardware. Their connections will quickly stabilize and the routine will return just as before. People with flaky hardware that takes a long time to settle down will now be able to use their devices. Checking the connect-changed status during the polling loop will make the test more conservative. The code will be able to detect transient disconnections that it would have missed before, and it won't return until the connection really _is_ stable. Furthermore, this makes the test compliant with the USB specification, which requires the stability timer to be restarted whenever a connection change occurs. Returning early for disconnections is a simple optimization. It's more important now that the total timeout length is 1.5 seconds rather than 0.4 seconds. I urge you to apply this patch and for people to try it out. If there do turn out to be problems... the patch is very small, well-contained, and easy to revert.

Only with the 2.6 module loader, there's no way to find out where the various sections in the module image ended up, so you can't do much. This patch attempts to fix that by adding a "sections" subdirectory to every module's entry in /sys/module; each attribute in that directory associates a beginning address with the section name. Those attributes can be used by a a simple script to generate an add-symbol-file command for gdb, something like: #!/bin/bash # # gdbline module image # # Outputs an add-symbol-file line suitable for pasting into gdb to examine # a loaded module. # cd /sys/module/$1/sections echo -n add-symbol-file $2 `/bin/cat .text` for section in .[a-z]* *; do if [ $section != ".text" ]; then echo " \\" echo -n " -s" $section `/bin/cat $section` fi done echo Currently, this feature is absent if CONFIG_KALLSYMS is not set. I do wonder if CONFIG_DEBUG_INFO might not be a better choice, now that I think about it. Section names are unmunged, so "ls -a" is needed to see most of them.

This patch adds a new data structure called the "partial page list" which helps the kernel keep track of precisely which 4k pages are in use by the IA-32 application. Armed with this data, the kernel can make better decisions at munmap and mprotect time. No significant performance degradation was observed in the workloads we tested and in some cases, the performance actually improved! This is possibly due to the reduced length of the vma list.

This patch attempts to put some order back into the situation. Details: Since usb_new_device() allocates neither the device structure nor the device address, it shouldn't release either one. Because usb_new_device() no longer releases the device structure, usb_register_root_hub() doesn't need to take an extra reference to it. Since the device address selection and TT setup code is used only for new devices, not ones being reset, move that code from hub_port_init() to hub_port_connect_change(). By the same token, hub_port_init() doesn't have to release the device address or the device structure. Just to make things look better, move the failure code in hub_port_init() to the end of the routine. And when disabling endpoint 0, disable both the IN and OUT parts of the endpoint. In hub_port_connect_change(), make all the failure paths execute the same code so that resources are always released. These resources comprise: the pointer from the parent to the new child device, the HCD state for ep0, the device's address, and the device structure itself -- in short, everything that's set up before calling usb_new_device().

This fixes some problems with the OIDs supported by the original RNDIS patch: - It included OIDs not found in the RNDIS spec. These have been removed. As a rule, these weren't exported in the "OIDs I support" list, and only a couple wouldn't fail those accesses, so this mostly changes what debug printk appears. - OIDs used for optional 802.3 statistics were partially supported. They're all in the OID list now, but the support is #ifdeffed out. (Those statistics were mostly just made up, anyway!) - "Required" OIDs for suspend, resume, and wakeup support weren't listed. Their messages are now defined, but support is #ifdeffed out. Seems the docs aren't entirely accurate, and Windows can behave reasonably without them. (This area needs help from someone who knows MS-Windows power management.)

However a bus does not always have a root hub, and the code does not check that the root_hub pointer is non-NULL. This patch fixes the problem, using the usb_bus_list_lock semaphore to synchronize access when root hubs are added or removed. In addition it seemed like a good idea to minimize the time that a non-fully-configured root hub is accessible through the bus's pointer. So this patch delays setting the pointer and holds usb_bus_list_lock while configuring a root hub. It turned out that a bunch of things needed to be changed for all this to work: Check for NULL root_hub pointer in usb_device_read() and usb_find_device(). Pass the root-hub device as a separate argument to hcd_register_root(). Make usb_register_root_hub() acquire the usb_bus_list_lock and set the bus->root_hub pointer. For consistency's sake, move the place where the children[] pointer to a non-root-hub device gets stored as close as possible to where usb_new_device() is called. Make usb_disconnect() acquire the usb_bus_list_lock when removing a root hub. Change usb_hcd_pci_remove() and the non-PCI host drivers so that they call usb_disconnect() with a pointer to the bus's root_hub pointer, not a pointer to a temporary variable. Change all the host controller drivers not to store the root_hub pointer in the bus structure but instead to pass it as a new argument to hcd_register_root(). I made some attempt to update the hc_sl811 driver along with the rest, but it's pretty clear that driver won't work in the current framework. Among other things, it never reads the root hub's device descriptor. To what extent is the driver really supported?

I tried to implement the missing feature and noticed that the device is quite peculiar (or either my system is broken), when trying to fill mac address registers (no matter whether io_ops is set): - If I write a byte (writeb) to an even i/o address it seems like actually a word was written (the next byte is set to 0). - If I write a byte to an odd i/o address my pc gets bad freezed. That made think of writing 16bit words (writew) for the memory address, as opposed to what most driver examples do. It works for me (I hope i set the lines at the right place in device_open function after the device is reset). I hope the code is clean enough and does not mess with byte ordering.

It started life as patches as226b, as280, and as275. Later it was merged into as226e and I added significantly to it. First, this patch introduces a new config option to allow people to enable write-protect detection for their USB devices. With some luck, we've finally got it right and can eventually remove this option in favor of enabling this behavior all the time. Next, we change how we force some flags on -- it turns out that there are some 'generic' entries in the SCSI devinfo which was overriding us when we didn't want it. Finally, we add a safety check to the workaround for GeneSys Logic devices -- if the max_sectors parameter has already been turned down, we won't turn it up.

It's primarily reproducable via adding delays into various disconnect and reset processing paths, but has also been encountered in the field. This patch started life as as281b, and was modified by me only to patch properly against current kernels. The main features of the patch are: Store the host pointer at the start of the control thread rather than trying to get it from srb->device; after the host is removed the SCSI device structure may no longer exist. Keep dev_semaphore locked during the entire time the control thread or reset handlers are using the us_data structure. Reorder the items in dissociate_dev() and release_resources() so that things are released in the opposite order from the way they were acquired originally. Don't bother to increment and decrement the usb_device's reference count; it's unnecessary. In disconnect(), first set the DISCONNECTING flag so that no more I/O will take place and no more requests will be accepted. Next, cut short the current command and wait for it to finish. Then call scsi_remove_host(). The SCSI core guarantees that when scsi_remove_host() returns, the host will not be in error recovery and all outstanding commands will have been cancelled. Remove some old useless left-over code that was #if'ed out. Use a wait_queue for the 6-second delay during device resets so that we can be woken up in the middle if a disconnect occurs. The key point here is that after scsi_remove_host(), everything is idle as far as the SCSI midlayer is concerned. But if there was a command in progress at the time, the midlayer will abort it without telling us or waiting for it to complete. Hence we have to wait for the control thread to be idle before we can try to kill it. This should happen quickly, since all I/O attempted by the thread will fail immediately.

There is a minor behavior change, such that, the Alt Status register is read before acknowledging the bmdma interrupt. This should be ok, and furthermore there will be more significant behavior changes in this area coming soon. <jgarzik@pobox.com> [libata] PCI IDE command-end/irq-acknowledge cleanup Restruct default irq handler (used for many PCI IDE-like SATA controllers) to obtain device status and acknowledge interrupts a bit differently. In an attempt to better attack the "ich5 screaming interrupt" problem, acknowledge and clear the device's INTRQ by reading the Status register _before_ ack'ing the controller's irq status. This is a deviation from how the Linux IDE driver acknowledges interrupts, but it may be the best method, since the ICH5 appears to continue to assert the interrupt bit in the BMDMA until the device INTRQ line is cleared. Of course, SATA has no INTRQ line per se, so ICH5 essentially has new interrupt behavior not seen before in the PCI IDE world, while pretending that it's compatible with PCI IDE. Sigh. This change affects all SATA controllers (for which there are libata drivers) except for sata_promise and sata_sx4. <jgarzik@pobox.com> [libata] ->qc_prep hook Rename ->fill_sg hook to ->qc_prep, and call it unconditionally (as opposed to ->fill_sg, which was called only when the flag ATA_QCFLAG_SG was set). <aia21@cantab.net> NTFS: sparse fix: void function with return (value) Sparse: ======= CHECK fs/ntfs/attrib.c fs/ntfs/malloc.h:57:15: warning: return expression in void function [repeated several times] From: Mika Kukkonen <mika@osdl.org> Signed-off-by: Randy Dunlap <rddunlap@osdl.org> Signed-off-by: Anton Altaparmakov <aia21@cantab.net> <aia21@cantab.net> NTFS: - Add new element itype.index.collation_rule to the ntfs inode structure and set it appropriately in ntfs_read_locked_inode(). - Implement a new inode type "index" to allow efficient access to the indices found in various system files and adapt inode handling accordingly (fs/ntfs/inode.[hc]). An index inode is essentially an attribute inode (NInoAttr() is true) with an attribute type of AT_INDEX_ALLOCATION. As such, it is no longer allowed to call ntfs_attr_iget() with an attribute type of AT_INDEX_ALLOCATION as there would be no way to distinguish between normal attribute inodes and index inodes. The function to obtain an index inode is ntfs_index_iget() and it uses the helper function ntfs_read_locked_index_inode(). Note, we do not overload ntfs_attr_iget() as indices consist of multiple attributes so using ntfs_attr_iget() to obtain an index inode would be confusing.

This layout to be required for WinCE and, thus, is the default for these loaders. The memory organization had been optimized for discontiguous blocks. Now, it supports a default mode that is compatible with all of the bootloaders as well as options to optimize for either contiguous or discontiguous models. Withing, there is also a slight change to the way that the DEBUG_LL macros select the UART address.

This is a resend of an earlier patch to dst_dev_event. I've changed it slightly by moving the input/output assignment into dst_ifdown. To recap, this patch drops lingering IPsec references to a device that is being unregistered. The child processing in the GC is too late since it never runs until the reference on the dst hits zero which could take a long time for things like TCP connections. The reason I've left the input/output assignment outside the loop is because they aren't really necessary for the IPsec dst's, and if it were in the loop then we'll have to do the same child processing in ___dst_free as well.

In particular we no longer save all of the registers for the common exceptions - system calls, hardware interrupts and decrementer (timer) interrupts - only the volatile registers. The other registers are saved and restored (if used) by the C functions we call. This involved changing the registers we use in early exception processing from r20-r23 to r9-r12, which ended up changing quite a lot of code in head.S. Overall this gives us about a 20% reduction in null syscall time. Some system calls need all the registers (e.g. fork/clone/vfork and [rt_]sigsuspend). For these the syscall dispatch code calls a stub that saves the nonvolatile registers before calling the real handler. This also implements the force_successful_syscall_return() thing for ppc64.

Russell King points out that on some architectures, with the move from 2.4 mm sweeping to 2.6 rmap, this may be a serious omission: very frequently referenced pages never re-marked young, and the worst choices made for unmapping. So, replace ptep_test_and_clear_young by ptep_clear_flush_young throughout rmap.c. Originally I'd imagined making some kind of TLB gather optimization, but don't see what now: whether worth it rather depends on how common cross-cpu flushes are, and whether global or not. ppc and ppc64 have already found this issue, and worked around it by arranging TLB flush from their ptep_test_and_clear_young: with the aid of pgtable rmap pointers. I'm hoping ptep_clear_flush_young will allow ppc and ppc64 to remove that special code, but won't change them myself. It's worth noting that it is Andrea's anon_vma rmap which makes the vma available for ptep_clear_flush_young in page_referenced_one: anonmm and pte_chains would both need an additional find_vma for that.

In a few words - this is a dynamic translator for IA-32 binaries on IPF platform. Following David Mosberger's advice - we use the binfmt_misc mechanism for the invocation of the translator whenever the user tries to exec an IA-32 binary. The EL is meant to help in the migration path from IA-32 to IPF. From our beta customers we learnt that at first stage - they tend to keep their environment mostly intact, using the legacy IA-32 binaries. Such an environment has, naturally, setuid and non-readable binaries. It will be useless to ask the administrator to change the settings of such an environment - some of them are very complex, and the administrators are reluctant to make any changes in a system that already proved itself to be robust and secure. So, our target with these patches is not to enhance the support for scripts but rather to allow a translator to be integrated into a working environment that is not (and should not be) aware to the fact it's being emulated. As I said before - it is practically hopeless to expect an administrator of such a system to change it so that it will suit the current behavior of binfmt_misc. But, even if we could do that, I'm not sure it would be a good idea - these changes are likely to be less secure than the suggested patches - - In order to execute non-readable binaries the binary will have to be made readable, which is obviously less secure than allowing only a trusted translator to read it - There will be no way for the translator to calculate the accurate AT_SECURE value for the translated process. This might end up with the translated process running in a non-secured mode when it actually needs to be secured. </background> I prepared a patch that solves a couple of problems that interpreters have when invoked via binfmt_misc. currently - 1) such interpreters cannot open non-readable binaries 2) the processes will have their credentials and security attributes calculated according to interpreter permissions and not those of the original binary the proposed patch solves these problems by - 1) opening the binary on behalf of the interpreter and passing its fd instead of the path as argv[1] to the interpreter 2) calling prepare_binprm with the file struct of the binary and not the one of the interpreter The new functionality is enabled by adding a special flag to the registration string. If this flag is not added then old behavior is not changed. A preliminary version of this patch was sent to the list on 9/1/2003 with the title "[PATCH]: non-readable binaries - binfmt_misc 2.6.0-test4". This new version fixes the concerns that were raised by the patch, except of calling unshare_files() before allocating a new fd. this is because this feature did not enter 2.6 yet. Arun Sharma <arun.sharma@intel.com> says: We were going through an internal review of this patch: http://marc.theaimsgroup.com/?l=linux-kernel&m=107424... which is in your tree already. I'm not sure if this line of code got sufficient review. + /* call prepare_binprm before switching to interpreter's file + * so that all security calculation will be done according to + * binary and not interpreter */ + retval = prepare_binprm(bprm); The case that concerns me is: unprivileged interpreter and a privileged binary. One can use binfmt_misc to execute untrusted code (interpreter) with elevated privileges. One could argue that all binfmt_misc interpreters are trusted, because only root can register them. But that's a change from the traditional behavior of binfmt_misc (and binfmt_script). (Update): Arun pointed out that calculating the process credentials according to the binary that needs to be translated is a bit risky, since it requires the administrator to pay extra attention not to register an interpreter which is not intended to run with root credentials. After discussing this issue with him, I would like to propose a modified patch: The old patch did 2 things - 1) open the binary for reading and 2) calculate the credentials according to the binary. I removed the riskier part of changing the credentials calculation, so the revised patch only opens the binary for reading. It also includes few words of warning in the description of the 'open-binary' feature in binfmt_misc.txt, and makes the function entry_status print the flags in use. As for the 'credentials' part of the patch, I will prepare a separate patch for it and send it again to the LKML, describe the problem and ask for people comments.

The way it is done is by calling prepare_binprm, which is where these attributes are calculated, before switching the 'file' field in the bprm from the binary to the interpreter. This feature should be used with care, since the interpreter will have root permissions when running a setuid binary owned by root. Please note - - Only root can register an interpreter with binfmt_misc. The feature is documented and the administrator is advised to handle it with care - The new feature is enabled only with a special flag in the registration string. When this flag is not specified the current behavior of binfmt_misc is kept - This is the only 'right' way for an interpreter to know the correct AT_SECURE value for the interpreted binary From: Chris Wright <chrisw@osdl.org> This patchset looks OK, except for one problem. It installs the fd (which could've been unreadable) without unsharing the ->files. So someone can use this to read unreadable yet executable files. Here's a patch which fixes that up. I added one bit that's commented out because I'm not positive if a final steal_locks() is needed. I did a fair amount of rearranging to simplify the error conditions relative to the fd_install(), and unshare_files(). From: Chris Wright <chrisw@osdl.org> I found that the intel patchset (and mine as well) leaked i_writecount on the original executed file. In addition, I verified that the steal_locks() bit is indeed needed.

One obvious solution is something like ext2's bitmap groups, which puts file data into different areas of the disk based on which subdirectory they are in. The problem with bitmap groups is that if you've got a group of subdirectories their contents will be spread out all over the disk, leading to lots of seeks during a sequential read. This allocator patch uses the packing locality to determine which bitmap group to allocate from, but when you create a file it looks in the bitmaps to see how 'full' that packing locality already is. If it hasn't been heavily used yet, the packing locality is inherited from the parent directory putting files in new subdirs close to the parent subdir, otherwise it is the inode number of the parent directory putting new files far away from the parent subdir. The end result is fewer bitmap groups for the same working set. For example, one test data set created by 20 procs running in parallel has 6822 subdirs. And with vanilla reiserfs that would mean 6822 packing localities. This patch turns that into 26 packing localities. This makes sequential reads of big directory trees more efficient, but it also makes the btree more efficient in general. Things end up sorted better because groups of subdirs end up with similar keys in the btree, instead of being spread out all over. The bitmap grouping code tries to use the start of each bitmap group for metadata, and offsets the data slightly. The data and metadata are still close together, but not completely intermixed like they are in the default allocator. The end result is that leaf nodes tend to be close to each other, making metadata readahead more effective. The old block allocator had the ability to enforce a minimum allocation size, but did not use it. It now tries to do a pass looking for larger allocation chunks before falling back to the old behaviour of taking any blocks it can find. The patch changes the defaults to: mount -o alloc=skip_busy:dirid_groups:packing_groups You can get back the old behaviour with mount -o alloc=skip_busy mount -o alloc=dirid_groups will turn on the bitmap groups mount -o alloc=packing_groups turns on the packing locality reduction code mount -o alloc=skip_busy:dirid_groups turns on both dirid_groups and skip_busy Finally the patch adds a mount -o alloc=oid_groups, which puts files into bitmap groups based on a hash of their objectid. This would be used for databases or other situations where you have a limited number of very large files.

The problem is that the IDR code uses 5-bit chunks of the number and the lower portion used by IDR is 24 bits, so you have one bit that leaks over into the comparisons that should not be there. The solution is to mask off that bit before doing IDR processing. This actually causes the POSIX timer code to crash if you create that many timers. I have included an idr_test.tar.gz file that demonstrates this with and without the fix, in case you need more evidence :). * When the IDR fills up, it returns -1. However, there was no way to check for this condition. This patch adds the ability to check for the idr being full and fixes all the users. It also fixes a problem in fs/super.c where the idr code wasn't checking for -1. * There was a race condition creating POSIX timers. The timer was added to a task struct for another process then the data for the timer was filled out. The other task could use/destroy time timer as soon as it is in the task's queue and the lock is released. This moves settup up the timer data to before the timer is enqueued or (for some data) into the lock. * Change things so that the caller doesn't need to run idr_full() to find out the reason for an idr_get_new() failure.

If it's for consistency across 32- and 64-bit machines, why not just make it "31"? - Does this still hold true with the counter removed? /* We can only use half the bits in the top level because there are only four possible bits in the top level (5 bits * 4 levels = 25 bits, but you only use 24 bits in the id). */ If not, what needs to change?

I've made some changes and tested with a lot of bounds. I don't have a machine with enough memory to fill it up (it would take ~16GB on a 64-bit machine), but I use the "above" code to simulate a lot of situations. The problems were: * IDR_FULL was not the right value * idr_get_new_above() was not defined in the headers or documented. * idr_alloc() bug-ed if there was a race and not enough memory was allocated. It should have returned NULL. * id will overflow when you go past the end. * There was a "(id >= (1 << (layers*IDR_BITS)))" comparison, but at the top layer it would overflow the id and be zero. * The allocation should return ENOSPC for an "above" value with nothing above it, but it returned EAGAIN. I have not tested on 64-bits (as I don't have a 64-bit machine). I've included the files, a diff from the previous version, and my test programs. For the test programs, idr_test <size> will just attempt to allocate <size> elements, check them, free them, and check them again. idr_test2 <size> <incr> will allocate <size> element with <incr> between them. idr_test3 just tests some bounds and tries all values with just a few in the idr.

The patch is versus BK-recent. I've also included a simple, reliable test case which demonstrates the problem this patch is intended to fix. (Note that BK-recent is not sufficient to address this test case, and waiting on the commiting transaction in ext3_new_block is also not sufficient. Been there, tried that, didn't work. We need to do the full-bore retry from the top level.

It validates the PM-Timer rate against PIT channel 2 and rejects the PM-Timer if its rate is not withing 5% of the expected number. Rationale: The PMTMR timers of certain (older) mainboards are running at invalid rates, often much faster than the rate expected by the PM-Timer code. This causes the system clock to run much too fast. See also http://bugme.osdl.org/show_bug.cgi?id=2375 Possible workarounds are disabling the PM-Timer in the kernel config or disabling the PM-Timer at boot time through the "clock=tsc" parameter. However, we believe it is more user friendly to automatically validate the PM-Timer rate at boot time before using it as the system time source.

Currently the following version numbers are defined: 0: old format (until 2.6.7) with 16 bit uid/gid 1: extended variant (binary compatible to v0 on M68K) 2: extended variant (binary compatible to v0 on everything except M68K) 3: a new binary incompatible format (64 bytes) 4: new binary incompatible format (128 bytes). layout of its first 64 bytes is the same as for v3. 5: marks second half of new binary incompatible format (128 bytes) (layout is not yet defined) All this is accomplished without breaking binary compatibility. 32 bit uid/gid support is compatible with the patch previously floating around and used e.g. by Red Hat. This patch also introduces a config option for a new, binary incompatible "version 3" format that - is uniform across and properly aligned on all platforms - stores pid and ppid - uses AHZ==100 on all platforms (allows to report longer times) Much of the compatibility glue goes away when v1/v2 support is removed from the kernel. Such a patch is at http://www.physik3.uni-rostock.de/tim/kernel/2.7/acct-cle... and might be applied in the 2.7 timeframe. The new v3 format is source compatible with current GNU acct tools (6.3.5). However, current GNU acct tools can be compiled for only one format. As there is no way to pass the kernel configuration to userspace, with my patch it will still only support the old v2 format. Only if v1/v2 support is removed from the kernel, recompiling GNU acct tools will yield v3 support. A preliminary take at the corresponding work on cross-platform userspace tools (GNU acct package) is at http://www.physik3.uni-rostock.de/tim/kernel/utils/acct/ This version of the package is able to read any of the v0/v2/v3 formats, regardless of byte-order (untested), even within the same file. Cross-platform compatibility with m68k (v1 format) is not yet implemented, but native use on m68k should work (untested). pid and ppid are currently only shown by the dump-acct utility.

It is similar to the last posting except this one implements the NFS get_parent() method which has always been missing. The original problem I set out to addresses is that the current iso9660 file system cannot reach inodes located beyond the 4GB barrier. This is caused by using the inode number as the byte offset of the inode data. Being 32-bits wide, the inode number is unable to reach inode data that does not reside on the first 4GB of the file system. This causes real problems with "growisofs" http://fy.chalmers.se/~appro/linux/DVD+RW/#isofs4gb and my pet project "shunt" http://www.serice.net/shunt/ This patch switches the isofs code from iget() to iget5_locked() which allows extra data to be passed into isofs_read_inode() so that inode data anywhere on the disk can be reached. The inode number scheme was also changed. Continuing to use the byte offset would have resulted in non-unique inodes in many common situations, but because the inode number no longer plays any role in reading the meta-data off the disk, I was free to set the inode number to some unique characteristic of the file. I have chosen to use the block offset which is also 32-bits wide. Lastly, the pre-patch code uses the default export_operations to handle accessing the file system through NFS. The problem with this is that the default NFS operations assume that iget() works which is no longer the case because of the necessity of switching to iget5_locked(). So, I had to implement the NFS operations too. As a bonus, I went ahead and implemented the NFS get_parent() method which has always been missing.

The main point of this patch is using HAS_MII instead of HAS_NWAY for the definition of the board. All the previous trials since the end of last year used HAS_NWAY which disables the Tx part of the transceiver; using HAS_NWAY was the way all 3Com Cyclone and Tornado chips worked, as they had the transceiver integrated. The ATI solution has an external transceiver and I had to physically see the different chip on the board (the board was provided by ATI) to finally understand that it needs the HAS_MII definition... I'm still waiting for some docs from ATI to clarify if this is the correct way of handling this chip and if there are any differences w.r.t EEPROM handling, but as it appears to work and was also confirmed by other testers, I don't want to keep owners of such boards away from their networks :-) The textual identification was a bit hard to decide; it's called "3c920B-EMB-WNM" in the Windows .INF file that Asus provides for their boards. As this name was already used for PCI ID 9210, I added the paranthesis which specifies where this chip is found. The Scyld driver defines FEATURE_TORNADO to include HAS_NWAY. This board would then probably need to not be defined with FEATURE_TORNADO, but the same as in this patch. I would like to publicly thank Tyson Vickers for both ideas and patience during the last few weeks. He managed to get the driver working by randomly setting driver parameters :-) But then he contacted me and worked with me towards the solution.

It replaces all uses of APIC_BROADCAST_ID and IO_APIC_MAX_ID with this in order to ensure. It also changes the checks during MP table parsing so the APIC ID is checked in tandem with the version number.

The bug is closely related to the 'margin' feature of scrolling, which means that if less than four lines should remain unvisible in the direction we are scrolling to, then we scroll a little bit more just to see those few lines. Kind of two small magnets at the borders of the buffer. This bug was also reported with maybe a less clear description by Stepan Koltsov (cc'ed just for fun) back in 2001 and he got no answer. I found it at http://seclists.org/lists/linux-kernel/2001/Nov/0080.html His patch simply disables margin support and hence everythings becomes okay, but you lose a nice feature. Here's a patch that retains margin support and fixes the bug. Works for me, tested for a week. No guarantee.

AFAIK, they are not Debian nor sparc specific but I'm not subscribed to linux-kernel mailing list and since I'm involved with boot-floppies (mainly for sparc), I think I'm right to report it here. Feel free to forward it upstream (I checked the latest 2.3.46 sources and it seems these bugs are still there). These bugs are not release critical. The latter just not gives the user a chance to overwrite TERM env var at boot time. It could be just inconvenient for serial console boot, and in this case, our busybox' init is already enforcing TERM=vt102. Nevertheless if it could not be fixed before the release, I could even write a workaround in busybox' init (it's just a matter of rewriting getenv()). At last, it does not affect sysvinit package because serial console tty is controlled by a getty process which is reading terminal settings on its command line (take a look in inittab for T0 entries, if any). Ok, here is my modest contribution to kernel hacking. I don't know much about kernel internals but it seems that argument parsing is a bit broken. One trivial patch for command line like "init=/bin/sh console=prom" where console=prom is replaced by lot of spaces in previous call to setup_arch() on sparc, therefore the line parsed by parse_options() is really "init=/bin/sh " and a lot of null args are pushed into argv_init. The other patch is for command line like "TERM=vt100" where both default & user TERM entries are pushed into the env array. Taking a look into /proc/1/environ, it shows up: HOME=/ TERM=linux TERM=vt100 It appears that ash (maybe other shells too) is giving the latter entry but glibc getenv() is giving the former. It is therefore impossible to get entry from the user in a C program like busybox' init (used in Debian boot-floppies). I guess getenv() is not written to support duplicate entries, therefore the kernel should avoid such construct.

This increases the accuracy of the delay functions largely: n usec delay on a system with loops_per_jiffy = 1500000 : n before after 1 1000 ticks 1499 ticks 10 14000 ticks 14999 ticks n usec delay on a system with loops_per_jiffy = 100000 : n before after 1 0 ticks 99 ticks 10 0 ticks 999 ticks 100 9000 ticks 9999 ticks As noted by Kurt Garloff, it's necessary to adjust for large loops_per_jiffies, as the multiplication of it with HZ fails for 4GHz or larger. So, John Stultz suggested multiplying xloops with 4 first, and multiplying with (HZ/4).

This is both an issue for small ndelay()s for _all_ values for loops_per_jiffy and for certain {n,u}delay()s for many loops_per_jiffy values. Assuming LPJ = 1501115 udelay(87) results in 130597 loops to be spent. However, 1000 * 130597 / 1501115 is 86.999997 us, so we're actually _rounding down_. 1000 * 130598 / 1501115 is 87.000662841, which would be the technically correct thing to do. Of course, for the TSC case this won't matter as the maths take some time, so the actual delay is 1000 * __udelay(x) / lpj + __OVERHEAD(x) Anybody worried about both the additional overhead and the fact that the overhead takes some time to run should add a check if (unlikely(xloops < OVERHEAD)) return; xloops -= OVERHEAD; to the delay() routines in arch/i386/kernel/timers/*.c and determine what the OVERHEAD is.

Charge sigqueue allocation and destruction to the user_struct rather than a global pool. This per user rlimit accounting obsoletes the global queued_signals accouting. The patch as charges the sigqueue struct allocation to the queue that it's pending on (the receiver of the signal). So the owner of the queue is charged for whoever writes to it (much like quota for a 777 file). The patch started out charging the task which allocated the sigqueue struct. In most cases, these are always the same user (permission for sending a signal), so those cases are moot. In the cases where it isn't the same user, it's a privileged user sending a signal to another user. It seems wrong to charge the allocation to the privleged user, when the other user could block receipt as long as it feels. The flipside is, someone else can fill your queue (expectation is that someone else is privileged). I think it's right the way it is. The change to revert is very small.

It is needed for three reasons: (1) So that the size can be bigger than MAX_ORDER. IBM have done some testing on their big PPC64 systems (64GB of RAM) with linux-2.4 and found that they get better performance if the sizes of the inode cache hash, dentry cache hash, buffer head hash and page cache hash are increased beyond MAX_ORDER (order 11). Now the main allocator can't allocate anything larger than MAX_ORDER, but the bootmem allocator can. In 2.6 it appears that only the inode and dentry hashes remain of those four, but there are other hash tables that could use this service. (2) Changing MAX_ORDER appears to have a number of effects beyond just limiting the maximum size that can be allocated in one go. (3) Should someone want a hash table in which each bucket isn't a power of two in size, memory will be wasted as the chunk of memory allocated will be a power of two in size (to hold a power of two number of buckets). On the other hand, using the bootmem allocator means the allocation will only take up sufficient pages to hold it, rather than the next power of two up. Admittedly, this point doesn't apply to the dentry and inode hashes, but it might to another hash table that might want to use this service. I've coelesced the meat of the inode and dentry allocation routines into one such routine in mm/page_alloc.c that the the respective initialisation functions now call before mem_init() is called. This routine gets it's approximation of memory size by counting up the ZONE_NORMAL and ZONE_DMA pages (and ZONE_HIGHMEM if requested) in all the nodes passed to the main allocator by paging_init() (or wherever the arch does it). It does not use max_low_pfn as that doesn't seem to be available on all archs, and it doesn't use num_physpages since that includes highmem pages not available to the kernel for allocating data structures upon - which may not be appropriate when calculating hash table size. On the off chance that the size of each hash bucket may not be exactly a power of two, the routine will only allocate as many pages as is necessary to ensure that the number of buckets is exactly a power of two, rather than allocating the smallest power-of-two sized chunk of memory that will hold the same array of buckets. The maximum size of any single hash table is given by MAX_SYS_HASH_TABLE_ORDER, as is now defined in linux/mmzone.h.

See File Times. This is used by programs that do backups, so that backing a file up does not count as reading it. Only the owner of the file or the superuser may use this bit. It is useful if you want to do something with the file atime (for instance, moving files that have not been accessed in a while to somewhere else, or something like Debian's popularity-contest) but you also want to read all files periodically (for instance, tripwire or debsums). Currently, the program that reads all files periodically has to use utimes, which can race with the atime update: A B open fstat read open read close close utimes And the file still has the old atime, instead of the new one from when B did the read from it. This problem does not happen if A uses O_NOATIME instead of utimes to preserve the atime. This patch adds the O_NOATIME constant for all architectures, but it would also be possible to add it one architecture at a time by defining it to 0 when not defined in asm-*.

It is also used by version 2 of the ov511 USB webcam driver, which will be merged in the near future. That will reduce some code duplication, since the existing ov511 has much of this code built-in.

The problem is that some IOMMU implementations have a maximum limit to the size of the number of contiguously mappable pages (admittedly, this limit is mostly in the resource management algorithms rather than the IOMMUs themselves). This patch adds this concept to the bio layer via the parameter BIO_VMERGE_MAX_SIZE which architectures can define in asm/io.h (if undefined, we assume it to be infinite, which is current behaviour). While adding this, I noticed several places where bio was making incorrect assumptions about virtual mergeability (none of which was a bug: bio was overestimating rather than underestimating). - The worst offender was bio_add_page(), which seemed never to check for virtual mergeability - I also fixed blk_hw_contig_segments() not to check the QUEUE_CLUSTER flag, and not to check the phys segment boundary. In order to track the hw segment size across bios, I had to introduce two extra bio parameters: bi_hw_front_size and bi_hw_back_size which store the sizes of the front and back hw contiguous segments (and which will be equal if there's only one hw segment). When the bio is merged into a request, these fields are updated with the total hw contig size so they can always be used to assess if the merger would violate the BIO_VMERGE_MAX_SIZE parameter.

The tda9887 module is basically completely rewritten and understands all the config bits now instead of having just some fixed config presets. Some of these config bits can be changed by insmod options now. The other big change is that both modules allow to use the V4L2 API for inter-module communication (i.e. when bttv/saa7134/... pass through the tuning ioctls to the modules). That allows to specify the TV norm more precisely (not just PAL but PAL-I, PAL-BG, ...), which is needed in some cases to make TV audio work correctly. Using the old v4l1 API is still possible so this shouldn't break any users of these two modules.

This can result in stack corruption. The fix is to kmalloc an array to hold the blocks, making sure to allocate something large enough. There was also a recent optimization to force the allocator to find a free region large enough to hold the entire preallocation size.

The driver takes the host_lock (with irqsave) at the entry to the ISR, and releases it at the exit. And inside the ISR there are potentially long busy-waits... Like int ctr = 6000000; /* only try for about a second */ while( --ctr && !((dstate = DC390_read8 (DMA_Status)) & DMA_XFER_DONE) && pSRB->SGToBeXferLen ); The attached patch is attempting to fix those places. Not sure if this is a proper fix though. In my understanding, after looking through the code, the host_lock is used to protect host-specific data and host-registers. The ->queuecommand is already called with it help, so, one just, basically, have to protect other contexts - interrupt, timer,... So, looks mostly right.

The problem is, since we've never actually logged out of the device and cannot do so in interrupt context, we must be sure to perform the logout before the qla2x00_fabric_login() in the RELOGIN_NEEDED code. 2) Sets the Get Port Database options to ZERO when issuing the call to qla2x00_get_port_database(). This consolidates actuall login handling in the place it should be, in the previous qla2x00_fabric_login() call rather than depending on any 'hidden' behaviour of the firmware. If a device did a LOGO after the login, then any subsequent exachanges will be returned with an 0x29 completion status and the RELOGIN_NEEDED code will handle the login. 3) Finally, if the master and slave state do not indicate a logged-in state from the Get Port Database call, then one cannot depend on the information returned from the firmware -- the firmware typically wipes out the PCB information for a given loopID when logged out.

The fix for this problem is to avoid such requests, in one of three ways, for the affect drive+controller combos: 1) Limit all writes to 15 sectors 2) Use block layer features to avoid creating requests whose length satisfies the above equation. 3) When a request satisfies the above equation, split the request into two writes, neither of which satisfies the equation. I chose fix #1, the most simple to implement. After discussion with Silicon Image and others regarding the impact of this fix, I have decided to remain with fix #1, and will not be implementing a "better fix". This means that the affected SATA drives will see decreased performance, but set of affected drives is small and will never grow larger. Further, the complexity of implementing solution #2 or solution #3 is rather large. When implementing lba48 'large request' support, I unintentionally broke the fix for these affected drives. Kudos to Ricky Beam for noticing this. This change restores the fix, by adding a flag ATA_DFLAG_LOCK_SECTORS to indicate that the max_sectors value set by the low-level driver should never be changed. <acme@conectiva.com.br> [NET] Generalise tcp memory pressure handling Signed-off-by: Arnaldo Carvalho de Melo <acme@conectiva.com.br> <benh@kernel.crashing.org> [PATCH] ppc32: Cleanups & warning fixes of traps.c This cleans up arch/ppc/kernel/traps.c and vecemu.c to use the same formatting style for all functions, and fixes 2 warnings in the altivec floating point emulation code.

This is unfortunatly not correct for a bunch of laptops where the real panel data are only present in the RAM image. This works around this problem by preferring the RAM image on mobility chipsets. This is definitely not the best workaround, we need some arch support for linking the RAM image to the PCI ID (preferrably by having the arch snapshot it during boot, isolating us completely from the details of where this image is in memory).

On PPC64 machines with Altivec (i.e. machines that use the PPC970 chip, such as the G5 powermac), the altivec floating-point instructions can operate in two modes: one where denormalized inputs or outputs are truncated to zero, and one where they aren't. In the latter mode the processor can take an exception when it encounters denormalized floating-point inputs or outputs rather than dealing with them in hardware. This patch adds code to deal properly with the exception, by emulating the instruction that caused the exception. Previously the kernel just switched the altivec unit into the truncate-to-zero mode, which works but is a bit gross. Fortunately there are only a limited set of altivec instructions which can generate the assist exception, so we don't have to emulate the whole altivec instruction set. Note that Altivec is Motorola's name for the PowerPC vector/SIMD instructions; IBM calls the same thing VMX, and currently only IBM makes 64-bit PowerPC CPU chips. Nevertheless, I have used the term Altivec in the PPC64 code for consistency with the PPC32 code.

It adds a bit-array of ports with logical connect-changes pending to the hub structure, so that the hub driver can recognize that these ports should be treated as though they had disconnected and re-connected. This is how we will handle devices that "morph" (i.e., change their descriptors) following a reset, as might happen with a firmware upload. There is also a lot of additional kerneldoc and a few small changes to some log messages. An important restriction is that usb_reset_device() will refuse to work if the device is suspended. Trying to reset a suspended device leads to several problems, not least of which is that the device's parent hub might be suspended as well.

Jack Steiner tested the first one on a 512p and it resolved the rcu cache line trashing. All were tested on osdl with STP. Step one for reducing cacheline trashing within rcupdate.c: The current code uses the rcu_cpu_mask bitmap both for keeping track of the cpus that haven't gone through a quiescent state and for checking if a cpu should look for quiescent states. The bitmap is frequently changed and the check is done by polling - together this causes cache line trashing. If it's cheaper to access a (mostly) read-only cacheline than a cacheline that is frequently dirtied, then it's possible to reduce the trashing by splitting the rcu_cpu_mask bitmap into two cachelines: The patch adds a generation counter and moves it into a separate cacheline. This allows to removes all accesses to rcu_cpumask (in the read-write cacheline) from rcu_pending and at least 50% of the accesses from rcu_check_quiescent_state. rcu_pending and all but one call per cpu to rcu_check_quiescent_state access the read-only cacheline. Probably not enough for 512p, but it's a start, just for 128 byte more memory use, without slowing down rcu grace periods. Obviously the read-only cacheline is not really read-only: it's written once per grace period to indicate that a new grace period is running. Tests on an 8-way Pentium III with reaim showed some improvement: oprofile hits: Reference: http://khack.osdl.org/stp/293075/ Hits % 23741 0.0994 rcu_pending 19057 0.0798 rcu_check_quiescent_state 6530 0.0273 rcu_check_callbacks Patched: http://khack.osdl.org/stp/293076/ 8291 0.0579 rcu_pending 5475 0.0382 rcu_check_quiescent_state 3604 0.0252 rcu_check_callbacks The total runtime differs between both runs, thus the % number must be compared: Around 50% faster. I've uninlined rcu_pending for the test. Tested with reaim and kernbench. Description: - per-cpu quiescbatch and qs_pending fields introduced: quiescbatch contains the number of the last quiescent period that the cpu has seen and qs_pending is set if the cpu has not yet reported the quiescent state for the current period. With these two fields a cpu can test if it should report a quiescent state without having to look at the frequently written rcu_cpu_mask bitmap. - curbatch split into two fields: rcu_ctrlblk.batch.completed and rcu_ctrlblk.batch.cur. This makes it possible to figure out if a grace period is running (completed != cur) without accessing the rcu_cpu_mask bitmap. - rcu_ctrlblk.maxbatch removed and replaced with a true/false next_pending flag: next_pending=1 means that another grace period should be started immediately after the end of the current period. Previously, this was achieved by maxbatch: curbatch==maxbatch means don't start, curbatch!= maxbatch means start. A flag improves the readability: The only possible values for maxbatch were curbatch and curbatch+1. - rcu_ctrlblk split into two cachelines for better performance. - common code from rcu_offline_cpu and rcu_check_quiescent_state merged into cpu_quiet. - rcu_offline_cpu: replace spin_lock_irq with spin_lock_bh, there are no accesses from irq context (and there are accesses to the spinlock with enabled interrupts from tasklet context). - rcu_restart_cpu introduced, s390 should call it after changing nohz: Theoretically the global batch counter could wrap around and end up at RCU_quiescbatch(cpu). Then the cpu would not look for a quiescent state and rcu would lock up.

This can be avoided with a sequence lock: A sequence lock allows to read the current batch number and next_pending atomically. If next_pending is already set, then there is no need to acquire the global mutex. This means that for each grace period, there will be - one write access to the rcu_ctrlblk.batch cacheline - lots of read accesses to rcu_ctrlblk.batch (3-10*cpus_online()). Behavior similar to the jiffies cacheline, shouldn't be a problem. - cpus_online()+1 write accesses to rcu_ctrlblk.state, all of them starting with spin_lock(&rcu_ctrlblk.state.mutex). For large enough cpus_online() this will be a problem, but all except two of the spin_lock calls only protect the rcu_cpu_mask bitmap, thus a hierarchical bitmap would allow to split the write accesses to multiple cachelines. Tested on an 8-way with reaim. Unfortunately it probably won't help with Jack Steiner's 'ls' test since in this test only one cpu generates rcu entries.

Or something. I really cannot see any logic behind this, so toss it out and change the arithmetic in there so that all pages on both lists have equal scan rates. - Chunk the work up so we never hold interrupts off for more that 32 pages worth of scanning. - Make the per-zone scan-count accumulators unsigned long rather than atomic_t.

The physical ordering of pages delivered to the IO subsystem is strongly related to the order in which fragments are subdivided from larger blocks of memory tracked by the page allocator. Consider a single MAX_ORDER block of memory in isolation acted on by a sequence of order 0 allocations in an otherwise empty buddy system. Subdividing the block beginning at the highest addresses will yield all the pages of the block in reverse, and subdividing the block begining at the lowest addresses will yield all the pages of the block in physical address order. Empirical tests demonstrate this ordering is preserved, and that changing the order of subdivision so that the lowest page is split off first resolves the sglist merging difficulties encountered by driver authors at Adaptec and others in James Bottomley's testing. James found that before this patch, there were 40 merges out of about 32K segments. Afterward, there were 24007 merges out of 19513 segments, for a merge rate of about 55%. Merges of 128 segments, the maximum allowed, were observed afterward, where beforehand they never occurred. It also improves dbench on my workstation and works fine there.

Waste of text size. - The debug code relies on __builtin_return_address(0) to keep track of the callers. According to rmk, gcc didn't inline some functions as expected and that resulted in useless debug output. This was probably caused by the large debug-only inline functions. The attached patche removes most inline functions: - the empty on release/huge on debug inline functions were replaced with empty macros on release/normal functions on debug. - spurious inline statements were removed. The code is down to 6 inline functions: three one-liners for struct abstractions, one for a might_sleep_if test and two for the performance critical __cache_alloc / __cache_free functions. Note: If an embedded arch wants to save a few bytes by uninlining __cache_{free,alloc}: The right way to do that is to fold the functions into kmem_cache_xy and then replace kmalloc with kmem_cache_alloc(kmem_find_general_cachep(),).

The driver will now compile again, and you can change to a high resolution text mode with stty. Known defects: doesn't play nice with X, nor fbset. C = Cosmetic change L = Logical change A = API change W = register Writing change (1-CA) fb_info and cirrusfb_info: - mostly cosmetic, but a lot less confusing, and no more nasty casting. It used to be stylish to embed struct fb_info_gen (now struct fb_info) as the first member of struct clgenfb_info (now struct cirrusfb_info), and then you'd cast to the deisred struct. Now we pass the size of our data structure to framebuffer_alloc(), and we make fb_info and cirrusfb_info reference each other with pointers (as in radeonfb). In the old code, there two declarations were common: clgenfb_info *fb_info; clgenfb_info *info; since there's also a 'struct fb_info' now, I found this really confusing, and unified usage as: cirrusfb_info *cinfo; fb_info *info; This accounts for a lot of the search and replace cosmetic upgrade. (2-A) All of the FB knowledge of FB internals is gone in 2.6 (3-LW) revised maxclock numbers (cirrusfb_board_info_rec.maxclock[5]) In my quest to get fbset to work, I borrowed some maxclock data from the X.Org tree for various chipsets. It didn't really seem to help. oh well. (3-LA) upgraded PCI registration Instead of doing PCI walking from the driver, we hand off a pci_device_id table to the PCI subsystem and just get called when it finds a relevant board. (4-L) striking lots of __init and __initdata specifiers I was running into some things not working when I moved the call to init_vgachip() from the driver registration to set_par(). I thought perhaps this was due to some things being marked __init accidentally so I axed said annotations. Turns out it was something else. See 5. (5-LA) delayed chip initialization, nasty double-set_par() pseudo-bug Tony says that the fb drivers shouldn't do any chipset initialization until they get a set_par() call. This way, fb modules can be safely unloaded if no one gets around to using them, and the vga_con -> fbcon hand off is smoother, as fbcon can still grab the back-scroll data from vga_con... In any case, moving the calls to init_vgachip() and fbgen_do_set_var() from driver initialization to set_par() revealed that the cirrus register-writing function needs to be called twice for a mode change to work. I don't understand why. (6-LA) split clgen_decode_var() into the bits that check the var and the bits that actually generate register information (par/regs) to write Adding modedb hooks here might actually fix fbset, i think... (7-LW) No longer write the palette in init_vgachip() nor in set_par(). Someone else (fbcon?) seems to be making its own calls to setcolreg() for us. (8-LW) setcolreg() -- while removing all of the console cruft, I had to try to reconstitute the palette code. I think I got this right, but I could be off -- the penguin boots in the correct colors at least ;-) (9-L) pan_display() - we don't do wrap, silly. that's only on the amiga. (10-L) pan+BLT - to make pan play nicely with copyarea()/fillrect() I had to add a couple of calls to cirrusfb_WaitBLT() to make sure the engine is idle.

But the implementation took that input argument as number of pages to free. It also decrement the config parameter as well. All give random behavior depend on how many hugetlb pages are in normal/highmem zone. A two line fix in try_to_free_low() would be: - if (!--count) - return 0; + if (count >= nr_huge_pages) + return count; But more appropriately, that function shouldn't return anything.

To make life more interesting, the 32-bit result gets zero-extended to 64 bits, which makes checking for a -1 return value more complicated than it should be. This patch changes call_prom and rtas_call to return an int, and makes the corresponding changes to use ints for the variables used to hold those return values. While I was doing this I finally got annoyed enough with the strings of prom_print() and prom_print_hex() calls that we do to write a simple prom_printf. I deliberately didn't use snprintf because the execution environment is weird at this point - we aren't running at the address we are linked at just yet - and I didn't want to inflict that on any code outside this file. I also did a prom_debug() macro, which eliminated a few ifdefs. There are also a bunch of other minor cleanups.

And no, it's not the old ->getlink() crap - procfs et.al. are not special-cased there. Here's how it works: * ->follow_link() still does what it used to do - replaces vfsmount/dentry in the nameidata it got from caller. However, it can also leave a pathname to be resolved by caller. * we add an array of char * into nameidata; we always work with nd->saved_names[current->link_count]. nd_set_link() sets it, nd_get_link() returns it. * callers of ->follow_link() (all two of them) check if ->follow_link() had left us something to do. If it had (return value was zero and nd_get_link() is non-NULL), they do __vfs_follow_link() on that name. Then they call a new method (->put_link()) that frees whatever has to be freed, etc. Note that absolute majority of symlinks have "resolve a pathname" as part of their ->follow_link(); they can do something else and some don't do that at all, but having that pathname resolution is very, very common. With that change we allow them to shift pathname resolution part to caller. They don't have to - it's perfectly OK to do all work in ->follow_link(). However, leaving the pathname resolution to caller will a) exclude foo_follow_link() stack frame from the picture b) kill 2 stack frames - all callers are in fs/namei.c and they can use inlined variant of vfs_follow_link(). That reduction of stack use is enough to push the limit on nested symlinks from 5 to 8 (actually, even beyond that, but since 8 is common for other Unices it will do fine). For those who have "pure" ->follow_link() (i.e. "find a string that would be symlink contents and say nd_set_link(nd, string)") we also get a common helper implementing ->readlink() - it just calls ->follow_link() on a dummy nameidata, calls vfs_readlink() on result of nd_get_link() and does ->put_link(). Using (or not using) it is up to filesystem; it's a helper that can be used as a ->readlink() for many filesystems, not a reimplementation of sys_readlink(). However, that's _MANY_ filesystems - practically all of them. Note that we don't put any crap like "if this is a normal symlink, do this; otherwise call ->follow_link() and let it do its magic" into callers - all symlinks are handled the same way. Which was the main problem with getlink proposal back then. That covers almost everything; the only cases left are nfs, ncpfs and cifs.

Other controllers make it hard to be forgiving in those cases. This patch updates all the gadget drivers to explicitly set the req->zero flag to reflect whether the USB spec says a ZLP "must" be sent by the device.

In particular, it's practical to stream isochronous data to/from userspace using this API, by keeping an endpoint's I/O queue from emptying. Each AIO "iocb" in userspace corresponds directly to one "usb_request" (and one kiocb) in the kernel. Their lifecycles, including cancelation, overlap completely. That's much of why the patch is so small (surprised the heck out of me!); that, and using copy_{to,from}_user() rather than trying fancy dma mapping tricks to attain zerocopy nirvana. The kernel AIO module forgot to export kick_iocb(), so this adds the missing declaration ... needed when using gadgetfs as a module.

Patches are against 2.4.26 and 2.6.7. The main difference with 9.0 is that the video_relase() routine is now hopefully in line with kernel requirements. I've also added one more ioctl() call, upon request. I'm also slightly in the dark on the status of the PWC in the 2.6 kernel; I've seen two patches: the first was a bad one, since it would crash your kernel when you unplug the cam. I've seen a second patch to reverse the first one, but I don't know if that went in. Either way, you might get a conflict in pwc-if.c in and about the pwc_video_release() routine; this patch was generated against the clean 2.6.7 kernel source.

This moves the code from drivers/serial/8250_hcdp.[ch] to drivers/firmware/pcdp.[ch], since it's no longer 8250-specific. It also obsoletes CONFIG_SERIAL_8250_HCDP, replacing it with CONFIG_EFI_PCDP (which defaults to Y for ia64). In a nutshell, HCDP tells us "these UARTs are available for use as a console," and it's up to the user to explicitly specify the console device. The kernel can guess in some cases, but not all. The PCDP (aka HCDP v2) tells us what we really want to know, namely, "this UART or VGA device is the console device." (It also has provision for support for new device types.)

Thats rather antisocial, we should at the very least return NULL and allow the caller to proceed (eg try another node). A quick look at alloc_bootmem_node usage suggests we should fall back to allocating from other nodes if it fails (as arch/alpha/kernel/pci_iommu.c and arch/x86_64/kernel/setup64.c do). The following patch does that. We fall back to the regular __alloc_bootmem when __alloc_bootmem_node fails, which means all other nodes are checked for available memory.

Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org> <mingo@elte.hu> [PATCH] NX (No eXecute) support for x86 we'd like to announce the availability of the following kernel patch: http://redhat.com/~mingo/nx-patches/nx-2.6.7-rc2-bk2-AE which makes use of the 'NX' x86 feature pioneered in AMD64 CPUs and for which support has also been announced by Intel. (other x86 CPU vendors, Transmeta and VIA announced support as well. Windows support for NX has also been announced by Microsoft, for their next service pack.) The NX feature is also being marketed as 'Enhanced Virus Protection'. This patch makes sure Linux has full support for this hardware feature on x86 too. What does this patch do? The pagetable format of current x86 CPUs does not have an 'execute' bit. This means that even if an application maps a memory area without PROT_EXEC, the CPU will still allow code to be executed in this memory. This property is often abused by exploits when they manage to inject hostile code into this memory, for example via a buffer overflow. The NX feature changes this and adds a 'dont execute' bit to the PAE pagetable format. But since the flag defaults to zero (for compatibility reasons), all pages are executable by default and the kernel has to be taught to make use of this bit. If the NX feature is supported by the CPU then the patched kernel turns on NX and it will enforce userspace executability constraints such as a no-exec stack and no-exec mmap and data areas. This means less chance for stack overflows and buffer-overflows to cause exploits. furthermore, the patch also implements 'NX protection' for kernelspace code: only the kernel code and modules are executable - so even kernel-space overflows are harder (in some cases, impossible) to exploit. Here is how kernel code that tries to execute off the stack is stopped: kernel tried to access NX-protected page - exploit attempt? (uid: 500) Unable to handle kernel paging request at virtual address f78d0f40 printing eip: ... The patch is based on a prototype NX patch written for 2.4 by Intel - special thanks go to Suresh Siddha and Jun Nakajima @ Intel. The existing NX support in the 64-bit x86_64 kernels has been written by Andi Kleen and this patch is modeled after his code. Arjan van de Ven has also provided lots of feedback and he has integrated the patch into the Fedora Core 2 kernel. Test rpms are available for download at: http://redhat.com/~arjanv/2.6/RPMS.kernel/ the kernel-2.6.6-1.411 rpms have the NX patch applied. here's a quickstart to recompile the vanilla kernel from source with the NX patch: http://redhat.com/~mingo/nx-patches/QuickStart-NX.txt update: - make the heap non-executable on PT_GNU_STACK binaries. - make all data mmap()s (and the heap) executable on !PT_GNU_STACK (legacy) binaries. This has no effect on non-NX CPUs, but should be much more compatible on NX CPUs. The only effect it has it has on non-NX CPUs is the extra 'x' bit displayed in /proc/PID/maps.

His testing is still in progress, but we believe it comes from a nasty locking deficiency I introduced in 2.6.7's anon_vma_prepare. Andrea's original anon_vma_prepare was fine, it needed no anon_vma lock because it was always linking a freshly allocated structure; but my find_mergeable enhancement let it adopt a neighbouring anon_vma, which of course needs locking against a racing linkage from another mm - which the earlier adjust_vma fix seems to have made more likely. Does anon_vma->lock nest inside or outside page_table_lock?

When initialising these lists we iterate over modifier combinations 0 .. MAX_NR_ZONES. However, this is only correct when there are at most ZONES_SHIFT flags.

This patch converts the 24*sizeof(long) field, ->private, to a void pointer for use by file_operations entrypoints. A ->dtor() method is added to the kiocb in order to support the release of dynamically allocated structures referred to by ->private. The sole in-tree users of ->private are async network read/write, which are not, in fact, async, and so need not handle preallocated ->private as they would need to if ->ki_retry were ever used. The sole truly async operations are direct IO pread()/pwrite() which do not now use ->ki_retry(). All they would need to do in that case is to check for ->private already being allocated for async kiocbs. This rips 88B off the stack on 32-bit in the common case.

Signed-off-by: Dave Jones <davej@redhat.com> <tony.luck@intel.com> [PATCH] ia64: fix reloc-out-of-range error on module loading I'm hitting this problem because the module I want to load was compiled with -g, so the filesize is absolutely huge. kernel/module.c does a vmalloc() to inhale the entire file, and then two calls to module_alloc() (which calls vmalloc() on ia64) to load the 'init' and 'core' sections. The 'init' is small and slips into a gap early in the vmalloc playspace, while the 'core' area is allocated after the huge area that was allocated for the inhaled copy of the whole file. I made a one coding change to Jean-Marc's version, adding a check to see whether the init/core sections are close enough together for the PCREL21B to reach (they almost always are). I've kept the test that there are no jumps from core to init (though the message that is printed is almost as unhelpful as the one that you get when you statically link a module into the kernel that has calls to the discarded .exit section :-) This patch stalled out before on the question of whether a PLT was overkill for a section-to-section branch, and whether it would be better to use relaxation techniques to extend the range. Doing that might be more elegant in some way, but it needs a whole heap of extra code (to count how many relaxed branches need to be added and allocated them as needed). This seems a lot of extra code that is only ever going to be exercised by maniacs like me with 49MB .ko files. I fixed up the comments to be a little more heplful.

Previous patch - open_nonreadable_binaries, offered the option of binfmt_misc opening the binary on behalf of the interpreter. In case binfmt_misc is requested to do that it would pass the file-descriptor of the open binary to the interpreter as its second argument (argv[1]). This method of passing the file descriptor was suspected to be problematic, since it changes the command line that users expect to see when using tools such as 'ps' and 'top'. The proposed patch changes the method of passing the fd of the open binary to the translator. Instead of passing it as an argument, binfmt_misc will request the ELF loader to pass it as a new element in the aux-vector that it prepares on the stack for ELF interpreter. With this patch, argv[1] will hold the full path to the binary regardless of whether it opened it or not.

There isn't much in the way of new features that have been added to the port yet, though I have added rough hugetlb and oprofile support. This patch doesn't really touch any common code, with the exception of an ifdef or two for keyboard support and an ifdef in fb.h to omit sh64 from the __raw_xxx() wrapping that sh does. The only other common driver changes were to sh-sci for serial support, but those bits were already merged with the latest batch of sh-sci updates. Beyond that, the port is completely isolated.

It ended up always being the zero page, and it was caused by a leaked reference in some do_wp_page() code that ends up avoiding PG_reserved pages. Basically what happens is that page_cache_release()/put_page() ignore PG_reserved pages, while page_cache_get()/get_page() go ahead and take the reference. So, each time there's a COW fault on the zero-page, you get a leaked page->count increment. It's pretty rare to have a COW fault on anything that's PG_reserved, in fact, I can't think of anything else that this applies to other than the zero page. In any case, it the bug doesn't cause any real problems, but it is a bit of an annoyance and is obviously incorrect.

However, the PCMCIA core has progressed, and now does not claim busy resources - IOW, it now behaves just like any other bus driver, where resources are allocated non-busy and its up to the drivers to mark their regions busy using request_region / request_mem_region. The effect of this is that the UPF_RESOURCES hack in the serial layer is now redundant, and can now be removed - 8250 devices should now always use request_region / request_mem_region unconditionally.

Since the SMP trampoline is a rare case of 'dynamic code' executed by the kernel (it has to be below 640K so it cannot be part of the kernel text itself), i've added the necessary infrastructure to enable/disable executability of specific kernel pages. We cannot simply disable NX via the MSR because we've got the NX bits in the kernel pagetables, which are set up before we do the SMP bootup. The NX bit in the pagetables is undefined if EFER.NXE is 0, so we cannot count on NX-capable CPUs not faulting when they encounter them. I've tested the x86 kernel on a non-NX SMP x86 box and on an NX UP box, on which i've also tested a simulated SMP trampoline, it all works fine. - add infrastructure to enable/disable executability of kernel pages - make the SMP trampoline page executable.

The args have to be in the RMO, but since we have a global spinlock for RTAS anyway, there's no reason to have a separate copy of the args per-CPU. This patch replaces the PACA field with a single instance in the global rtas structure. The one exception is for the rtas_stop_self() call, which can't take the lock, because it never returns. But it has a fixed set of arguments, so we can use another global instance which is initialized at boot. This lets us remove rtas.h from paca.h, which substantially reduces overall #include hairiness (because paca.h is now, as it wants to be, a nice low-level structure-defining header which relies on very little and can safely be included almost anywhere). Although it does add some noise to the patch, because a bunch of places relied on the indirect inclusion of rtas.h, or even more indirect inclusions (see the hunks applying to eeh.h and current.h!).

The rtas_args used to communicate with firmware are always taken from the paca struct, so as to keep the args at a fixed, low-memory location.

The standard is, IMNSOHO, a bit vague on just how repeating timers are to be handled so I made some choices: 1) If an absolute timer is to expire every N intervals, we assume that the expiries should happen at those specified times after clock setting. I.e. we adjust the repeat timer as well as the initial timer. (The other option would be to treat the repeating timers as relative and not to adjust them.) 2) If a clock set moves the the clock prior to the initial expiry time AND that time has already passed and been signaled, the current repeat timer is adjusted, i.e. we DO NOT go back to the initial time and repeat that. (The other option is to treat this case as a new request with the initial timer parameters (which by this time we have lost).) 3) If time is advanced such that it appears that several expiries have been missed, the overrun count will reflect the misses. (The other option is to not reflect this in the overrun.) At the same time, nothing is done to acknowledge, to the user, that we are repeating expiries when the clock is retarded.

The reason for the claim: 2.4 putcs - draw small amounts of data a lot of times 2.6 putcs - draw larger amounts of data a fewer times The way characters are drawn in 2.6 is optimal for accelerated drivers but should also give a speed boost for drivers that rely on software drawing. However the penaly incurred when preparing a large bitmap from a number of small bitmaps is currently very high. This is because of the following reasons: 1 fb_move_buf_{aligned|unaligned} uses pixmap->{out|in}buf. This is very expensive since outbuf and inbuf methods process only a byte or 2 of data at a time. 2 fb_sys_outbuf (the default method for pixmap->outbuf) uses memcpy(). Not a good choice if moving only a few bytes. 3 fb_move_buf_unaligned (used for fonts such as 12x22) also involves a lot of bit operations + a lot of calls to outbuf/inbuf which proportionately increases the penaly. So, I thought of separating fb_move_buf_* to fb_iomove_buf_* and fb_sysmove_buf_*. fb_iomove_buf_* - used if drivers specified outbuf and inbuf methods fb_sysmove_buf_* - used if drivers have no outbuf or inbuf methods *Most, if not all drivers fall in the second category.

The speed gain is constant but significant. Below is a patch against 2.6.7-mm5. The effects will be very noticeable with drivers that uses SCROLL_REDRAW, but one should still see some speed gain even if SCROLL_YPAN/YWRAP is used. Separated fb_sys_move_* into fb_iosys_move_* and fb_sysmove_* to reduce penalty when constructing fb_image->data from character maps. In my testcase (1024x768 SCROLL_REDRAW), I get a ~1.7 second advantage with 'time cat MAINTAINERS' using 8x16 fonts and ~5.7 seconds with 12x22 fonts. The speed gain is independent of acceleration or color depth.

While getting hands-on with netkit (www.netkit.org), a networking simulation environment based on UML, it struck me that ifconfig wasn't capable of calculating the proper broadcast address for a subnetted interface. Some browsing through newsgroups and on the Debian package site (nettools), showed that this leads to misconfigured interfaces and a couple of bugreports on ifconfig. Digging a bit deeper revealed that it actually is an issue with SIOIFNETMASK. Once you bring up an interface with SIOIFADDR, a classfull netmask and broadcast address is set (if applicable for the type of interface), in order to get a properly configured interface. But if you subnet the network using SIOIFNETMASK no proper broadcast address is set. So you always have to calculate it yourself, obviously leading to configuration errors. This patch takes care of this. First of all it doesn't change existing functionality, eg. a command like 'ifconfig eth0 192.168.1.1 netmask 255.255.255.240 broadcast 192.168.1.0' still works. But if you omit the broadcast address, a proper 'all ones' broadcast address for the subnet is set. 'ifconfig eth0 192.168.1.1 netmask 255.255.255.240' gives you 'eth0 inet addr:192.168.1.1 Bcast:192.168.1.15 Mask:255.255.255.240' and this should solve some real life problems.

That is, if the size of the compressed payload plus the size of the IPCOMP header is less than that of the original payload. This means that the IPCOMP encapsulation does not impose any overhead at all as far as the MTU is concerned. The current code incorrectly reduces the MTU by the size of the IPCOMP header.

From Petr Vandrovec <vandrove@vc.cvut.cz>. Begin quote yesterday I finally found why 2.6.x has problems with taking over vgacon. Problem is that take_over_console does: if (IS_VISIBLE) save_screen(i); ... visual_init(i, 0); ... so code nicely saves screen contents, and calls visual_init, which calls fbcon's init, which in turn can issue vc_resize. And this vc_resize will trigger read from vc->vc_origin. But vc_origin still points to videomemory, not to the buffer where save_screen() copied its data. End quote So updating vc->vc_origin to point to screenbuf after the previous console deinitializes allows fbcon to correctly update the screen from the screen buffer. This change makes the clearing of vram (using fillrect) unnecessary. 2. If FBINFO_MISC_MODESWITCH flag is set in info, do the set_par() in fbcon_switch() instead of piggy-backing the set_par() on fbcon_resize(). This preserves the current var, skipping the unnecessary fb_find_mode() step.

An increase of 3-10 times in scrolling speed can be expected. Currently, fbcon has 4 different scrolling methods (1-4). Potentially, we can have 6. This patch implements SCROLL_PAN_REDRAW (5). SCROLL_WRAP_REDRAW (6) is still unimplemented. Scroll Mode Operation YPan YWrap +++++++++++++++++++++++++++++++++++++++++++++++++++++ 1. SCROLL_ACCEL copyarea No No 2. SCROLL_REDRAW imageblit No No 3. SCROLL_PAN copyarea Yes No 4. SCROLL_WRAP copyarea No Yes 5. SCROLL_PAN_REDRAW imageblit Yes No 6. SCROLL_WRAP_REDRAW imageblit No Yes +++++++++++++++++++++++++++++++++++++++++++++++++++++ Note 1: I've changed the nomenclature to increase clarity: SCROLL_ACCEL = SCROLL_MOVE SCROLL_REDRAW = SCROLL_REDRAW SCROLL_PAN = SCROLL_PAN_MOVE SCROLL_WRAP = SCROLL_WRAP_MOVE To demonstrate the effect of each of the scrolling methods on an unaccelerated PCI/AGP-based driver (vesafb), I used a simple benchmark (time cat linux/MAINTAINERS - a 50K text file). The framebuffer is set at: 1024x768-8bpp, 8x16 font, yres_virtual = 2*yres 1. SCROLL_MOVE: real 5m50.277s user 0m0.001s sys 5m50.227s Almost 6 minutes for a 50K text file. Using soft copyarea on a PCI-based card is just too slow (because copyarea has to read from the framebuffer memory). 2. SCROLL_PAN_MOVE scrollmode: SCROLL_PAN real 0m8.592s user 0m0.000s sys 0m8.586s Using ypan with copyarea dramatically improves the scrolling. However, the scrolling action is jerky (fast during the panning stages, slows down during the copyarea stages). 3. SCROLL_REDRAW (this is the default scrolling mode) real 0m3.189s user 0m0.000s sys 0m3.170s Simply eliminating the copyarea, even without ypanning, makes it faster than SCROLL_PAN_MOvE. Plus, the scrolling action is smoother. So, if we combine YPanning with imageblit (PAN_REDRAW), we get this: 4. SCROLL_PAN_REDRAW real 0m0.520s user 0m0.000s sys 0m0.518s That's almost 6x faster than SCROLL_REDRAW. Increasing the amount of video RAM still increases the speed, but not very dramatically. Higher than 16 MB, the increase is negligible. Using an accelerated driver, we see almost the same effect but not as dramatically: 1. SCROLL_MOVE - accel real 0m3.112s user 0m0.000s sys 0m3.112s 2. SCROLL_REDRAW - accel real 0m2.604s user 0m0.000s sys 0m2.603s Redraw is still faster than move, but not much. 3. SCROLL_PAN_MOVE - accel real 0m0.203s user 0m0.000s sys 0m0.202s 4. SCROLL_PAN_REDRAW - accel real 0m0.326s user 0m0.002s sys 0m0.323s This is one exception. If panning is enabled, move is actually faster than redraw. As to why, I don't know. So based on the above, fbcon will choose the scrolling method based on the following preference: Ypan/Ywrap > accel imageblit > accel copyarea > soft imageblit > (soft copyarea) Note 2: Exception: accel copyarea > accel imageblit if Pan/Wrap is enabled. Note 3: soft copyarea will be avoided by fbcon as much as possible unless there is a specific override, ie., FBINFO_READS_FAST flag is set. If this flag is set, fbcon will prefer copyarea over imageblit, accel or soft. As a final note, in order for fbcon to use the best scrolling method, the low-level drivers must provide the correct hinting by setting the FBINFO_HWACCEL_* flags.

It also adds support for such mountpoints to be degraded at the filesystem's behest until they've been untouched long enough that they'll be removed. I've a patch (to follow) that removes some #ifdef's from fs/afs/* thus allowing it to make use of this facility. There are five pieces to this: (1) Any interested filesystem needs to have at least one list to which expirable mountpoints can be added. Access to this list is governed by the vfsmount_lock. (2) When a filesystem wants to create an expirable mount, it calls do_kern_mount() to get a handle on the filesystem it wants mounting, and then calls do_add_mount() to mount that filesystem on the designated mountpoint, supplying the list mentioned in (1) to which the vfsmount will be added. In kAFS's case, the mountpoint is a directory with a follow_link() method defined (fs/afs/mntpt.c). This uses the struct nameidata supplied as an argument as a determination of where the new filesystem should be mounted. (3) When something using a vfsmount finishes dealing with it, it calls mntput(). This unmarks the vfsmount for immediate expiry. There are two criteria for determining if a vfsmount may be expired - it mustn't be marked as in use for anything other than being a child of another vfsmount, and it must have an expiry mark against it already. (4) The filesystem then determines the policy on expiring the mounts created in (2). When it feels the need to, it passes the list mentioned in (1) to mark_mounts_for_expiry() to request everything on the list be expired. This function examines each mount listed. If the vfsmount meets the criteria mentioned in (3), then the vfsmount is deleted from the namespace and disposed of as for unmounting; otherwise the vfsmount is left untouched apart from now bearing an expiration mark if it didn't before. kAFS's expiration policy is simply to invoke this process at regular intervals for all the mounts on its list. (5) An expiration facility is also provided to userspace: by calling umount() with a MNT_EXPIRE flag, it can make a request to unmount only if the mountpoint hasn't been used since the last request and isn't in use now. This allows expiration to be driven by userspace instead of by the kernel if that is desirable. This also means that do_umount() has to use a different version of path_release() to everyone else... it can't call mntput() as that clears the expiration flag, thus rendering this unachievable; so it's version of path_release() calls _mntput(), which doesn't do the clear. My original idea was to give the kernel more knowledge of automounted things. This avoids a certain problem with stat() on a mountpoint causing it to mount (for example, do "ls -l /afs" on a machine with kAFS), but Al wanted it done this way. > Why is autofs unsuitable? Because: (1) Autofs is flat; AFS requires a tree - mounts on mounts on mounts on mounts... (2) AFS holds the data as to what the mountpoints are and where they go, and these may be cross-links to subtrees beyond your control. It's also not trivial to extract a list of mountpoints as is required for autofs. (3) Autofs is not namespace safe. (4) Ducking back to userspace to get that to do the mount is pretty tricky if namespaces are involved. In fact, autofs may well want to make use of this facility.

After that the confused path really becomes confused and it writes nothing and fs corruption triggers silenty (the reugular writepage only writes bh that are marked dirty, it never attempts to submit_bh anything marked clean). The mpage-writepage code must never mark the bh clean as far as it wants to still fallback in the regular writepage which depends on the bh to be dirty (i.e. the "goto confused" path). This could only triggers with memory pressure (it also needs buffer_heads_over_limit == 0, and that is frequent under mm pressure). Thanks a lot to Chris for his fine debugging that localized the problem in the writepage code.

The "offset" and the "end_index" were not coherent. this is writepages and it runs w/o the i_sem, so the i_size can change from under us anytime. If a parallel write happens while writepages run, the i_size could advance from 4095 to 4100. With the current 2.6 code that could translate in end_index = 0 and offset = 4. That's broken because end_index and offset could be not coherent. Either end_index=1 and offset =4, or end_index = 0 and offset = 4095. When they lose coherency the memset can zeroout actual data. The below patch fixes that (it's at least a theoretical bug). I don't really expect this tiny race to fix the bug in practice after the more serious bugs we covered yesterday didn't fix it (more likely the compiler will get involved into the equation soon ;). This is also an optimization for 32bit archs that needs special locking to read 64bit i_size coherenty. This patch also arranges for mpage_writepages() to always zero out the file's final page between i_size and the end of the file's final block. This is a best-effort correctness thing to deal with errant applications which write into the mmapped page beyond the underlying file's EOF.

Due to PCI rules the stores happen in order. However the cpu may reorder the reads. In these sort of cases there is usually a data dependency between reading the index and looking up the data (since we use the index to load the data). I think all cpus except alpha guarantee the reads happen in order in this case. However in this particular case we load hw_idx, compare it to sw_idx and then use sw_idx to locate the opaque cookie. There is no data dependency in this case. We need a read memory barrier between the read of rx_producer and the opaque cookie to enforce ordering.

Signed-off-by: Greg Kroah-Hartman <greg@kroah.com> <stern@rowland.harvard.edu> [PATCH] USB: Add usb_kill_urb() This patch is a slightly revised version of as277c, updated to match the current source. The only difference from the older version is that this makes urb->use_count into an atomic_t, to avoid the overhead of an extra locking step each time an URB is submitted and given back. The important features of this patch are: -EPERM added to Documentation/usb/error-codes.txt. Failure to use URB_ASYNC_UNLINK with usb_unlink_urb() is deprecated in the documentation. New ->reject and ->use_count fields added to struct urb. The reject field is protected by urb->lock, and locking is required only in usb_kill_urb() which doesn't have to be fast. Single wait_queue used for all processes waiting inside usb_kill_urb(). The wait queue is woken up only when an URB is given back with ->reject set. usb_rh_status_dequeue() changed to return int. It looks like this function should be declared static; it's not used outside the hcd.c file. Prototype for unlink_urb() in struct usb_operations is changed to include a status code argument. This is necessary so that the different unlink paths can return -ENOENT and -ECONNRESET as appropriate. Support for synchronous usb_unlink_urb() has been removed; such calls are passed to usb_kill_urb(). Kerneldoc for usb_unlink_urb() is updated. usb_kill_urb() added to urb.c. hc_simple() host driver is partially updated -- it should compile but it won't really work right.

In addition to implementing the remount function, it removes the parse_options() call from usb_fill_super and adds a "ignore" flag around the mounting that gets done in create_special_files. The parse_options call in usb_fill_super is removed because it is not needed when remount is implemented. The ignore_mount flag is needed because the simple_pin_fs function calls remount with no mount options - i.e. it's not a real mount. So the mount options would be cleared out. The ignore_mount flag causes the remount function to only act on real mounts.

This is a second step during enumeration, which lets the hub see the new device. (Based on a patch by Alex Sanks <alex@netchip.com>.) * Control over VBUS current draw. So for example this is what a gadget driver uses during SET_CONFIGURATION to say "it's OK to draw 300 mA from VBUS to recharge". - Basic interfaces to support device-side USB OTG. Feature flags and descriptors are in <linux/usb_ch9.h> already. * Reports whether the device has a Mini-AB port, so that OTG support (desriptors etc) is required. * Reports OTG device feature flags for HNP.

I have not divided the patch in two logical sub-patches becouse of two independent changes in one common file, KConfigure. More informations about the SN9C10[12] can be found below in the documentation. The driver is marked as "EXPERIMENTAL", meaning that there are no known bugs, but further testing is necessary before considering it stable. This the first driver using the new SBGGR8 video format, which has been recently added to the mainline kernel, so there are no available user application at the moment: this is one more reason why it should be in the kernel now. Changes in W996[87]CF: - remove w9968cf_externaldef.h now that ovcamchip.h is in the kernel; - mark user pointers with __user in a cleaner way to avoid sparse warnings; - use appropriate exclusive wait macro during open(); - replace info(), err(), warn() with dev_info(), dev_err(), dev_warn(), pr_debug(), pr_info(); - replace usb_unlink_urb() + wait_for_completion() with usb_kill_urb(); - fix memory offsets for buffers in the chip to be used with generic image sensors; - 'vppmod_load', 'debug', 'specific_debug' and 'simcams' module parameters are now writeable by default; - fix possible race conditions between disconnect() and open(); - add automatic 'ovcamchip' module loading option with 'ovmod_load' module parameter; - get rid of deprecated intermodule communication routines and use the correct module registration/unregistration approach; - remove period at the end of kernel messages; - fix several typos; - use MODULE_VERSION() macro; - other small internal cleanups; - documentation updates.

This patch just adds a few key flags in usb_bus, needed by usbcore (during enumeration) and by HCD and OTG controllers on OTG-capable boards. - Related bugfix: power budgeting is supposed to place a 100mA per port (non-OTG) for bus-powered devices.

The SMP trampoline would corrupt page 2, which was sometimes used for other data. This corrupted the ioport/iomem list in some cases and causes oopses while read /proc/iomem.

The reason was that highmem_start_start page ended up zero and that triggered the highmem check in change_page_attr when the slab debug code would unmap a kernel mapping.

When you have two serial drivers, (e.g. 8250 and PMAC_ZILOG) they both say "I want to reserve X ports starting with major TTY_MAJOR and minor 64". By the time pmac_zilog gets there, the ports it requests are already reserved. Unfortunately, init_pmz() doesn't check for pmz_register() failure, and so it merrily goes on to register the half-initialized pmac_zilog driver with the power management subsystem. This path provides a proper failure path. Also: Restore ppc configs now that I know people use AT Keyboards on CHRP and PReP machines, and the zilog driver is no longer Oops'ing.

If this bit is set then PROT_READ will also add the PROT_EXEC bit - as expected by legacy x86 binaries. The ELF loader will automatically set this bit when it encounters a legacy binary. This approach avoids the problems the previous ->def_flags solution caused. In particular this patch fixes the PROT_NONE problem in a cleaner way (http://lkml.org/lkml/2004/7/12/227), and it should fix the ia64 PROT_EXEC problem reported by David Mosberger. Also, mprotect(PROT_READ) done by legacy binaries will do the right thing as well. the details: - the personality bit is added to the personality mask upon exec(), within the ELF loader, but is not cleared (see the exceptions below). This means that if an environment that already has the bit exec()s a new-style binary it will still get the old behavior. - one exception are setuid/setgid binaries: these will reset the bit - thus local attackers cannot manually set the bit and circumvent NX protection. Legacy setuid binaries will still get the bit through the ELF loader. This gives us maximum flexibility in shaping compatibility environments. - selinux also clears the bit when switching SIDs via exec(). - x86 is the only arch making use of READ_IMPLIES_EXEC currently. Other arches will have the pre-NX-patch protection setup they always had. I have booted an old distro [RH 7.2] and two new PT_GNU_STACK distros [SuSE 9.2 and FC2] on an NX-capable CPU - they work just fine and all the mapping details are right. I've checked the PROT_NONE test-utility as well and it works as expected. I have checked various setuid scenarios as well involving legacy and new-style binaries. an improved setarch utility can be used to set the personality bit manually: http://redhat.com/~mingo/nx-patches/setarch-1.4-3.tar.gz the new '-X' flag does it, e.g.: ./setarch -X linux /bin/cat /proc/self/maps will trigger the old protection layout even on a new distro.

It turns out the pid hash is being sized way too small, eg on a 16GB box: PID hash table entries: 16 (order 4: 256 bytes) The reason is that the pid hash init function uses max_pfn before it was setup on ppc64.

This Makefile allow one to use make in the output directory without the hassle of going back to the kernel source tree. The O= option is added by this Makefile stub. Please note that the Makefile silently overwrite an old one, so changes will be lost if modified. If there is a need to tweak a Makefile in the output directory it is recommended to use the filename 'makefile', which GNU Make will try first. Signed-off-by: Sam Ravnborg <sam@ravnborg.org> <sam@mars.ravnborg.org> kbuild: Introduce source symlink in /lib/modules/.../ Traditionally when building a kernel the source and the output files are mixed. When building a kernel using the O= syntax to save output files in a separate directory a way is needed to locate the kernel source. The implemented solution is a new symlink 'source' being added to /lib/modules/.../ used to locate source for an installed kernel. The original symlink build points to the directory containing the output files. Please note that when the kernel is build with source and output files mixed the two symlinks 'build' and 'source' will point to the same directory, thus no changes compared to before. Two options was considered: a) Adding a new symlink pointing to the output files "object" => All external modules have to specify O= to build => External modules grepping in .config or .h files in include/asm needs to be updated => External modules that do grep in source code and ordinary header files just works b) Let the build symlink point to the output files and introduce a new symlink "source" pointing to the kernel source => External module can be build without specifying O= => External modules grepping in .config or .h files in include/asm just works => External modules that do grep in source code and ordinary header files needs to be updated Based on the above option b) is considered the least painfull alternative. So to sum up: - If a distro does not use separate output dir => no change - If a distro uses separate output dir => - Trivial external module just builds - Non-trivial (build-wise) external modules are probarly broken Without this patch - If a distro does not use separate output dir => no change - If a distro uses separate output dir => - Trivial external modules had to specify O= to build, and the directory being pointed at was not obvious - grep in .config or include files in asm/ required knowledge where to locate output files Preferred syntax for building external modules are the following: make -C /lib/modules/`uname -r`/build M=`pwd` [Substituting 'M=...' with 'SUBDIRS=... modules' give same effect]. When the kernel is built using separate output directory the above invocation of make will invoke the generated Makefile located in the output directory - that again will invoke the Makefile located in the kernel source tree root.

Thanks to Miyazawa-san for notifying me of the problem. In that patch I removed the nh_offset parameter to ipv6_clear_mutable_options. That broke ah6_input() because it relies on that variable to set the nexthdr. The following patch fixes this by moving this work out to the caller xfrm6_rcv() where the information is already available. It also removes an unnecessary call to ip6_find_1stfragopt() in xfrm6_rcv() since nhoffp already points to the nexthdr preceding the current header.

Oleg didn't explicitly ACK this, but I think he did implicitly: Oleg? The previous patch to install_page, returning an error if !page_mapping once page_table_lock is held, is not enough to guard against vmtruncate. When unmap_mapping_range already did this vma, but truncate_inode_pages has not yet done this page, page->mapping will still be set, but we must now refrain from inserting the page into the page table. Could check truncate_count, but that would need caller to read and pass it down. Instead, recheck page->index against i_size, which is updated before unmap_mapping_range. Better check page->mapping too: not really necessary, but it's accidental that index is left when mapping is reset. Also, callers are expecting -EINVAL for beyond end of file, not -EAGAIN.

But it looks like these days it's safe to drop and reacquire page lock if down_read_trylock fails: the page lock is held to stop try_to_unmap unmapping the page's ptes as fast as try_to_unuse is mapping them back in; but the recent fix for get_user_pages works to prevent that too.

This does not seem to be okay in 2.6.7 kernel. I was able to fix this by defining a new module_init routine which in turn calls ipmi_init_msghandler(). I also removed __init from ipmi_init_msghandler() since it gets called from ipmi_open() on an open of the ipmi device file.

Improve description of what the laptop_mode knob means (i.e. seconds between last I/O and automatic sync). * Document the most relevant config file options. * Change the installation instructions in the laptop mode doc to describe the ACPI-bound version first, because this is the easiest. Explain the non-ACPI version afterwards. Added a reference to my "packaged version" of the scripts. * Move the setting of hdparm and cpu frequency out of the ACPI script and into the core laptop mode script. Add config option DO_HD to enable hdparm. Add config setting HD to set device to do hdparm on. Rename Dax's CPU_MANAGE to DO_CPU, with 0/1 instead of yes/no, to improve consistency. * Fix a problem where the root filesystem wouln't be remounted when /etc/mtab listed its type as "unknown". Deduce the type of "unknown" filesystems from /etc/fstab. This depends on the patch that adds config files, which was submitted to Linus by Dax Kelson on July 10.

Without bh a not uptodate page will trigger a full readpage from disk, that overwrites the pagecache before the multi-bio gets submitted, generating fs corruption. I believe the below patch should fix it (untested) against kernel CVS. The testcases developed by Kurt showed the pagecache being overwritten with on-disk data at block offsets, and Chris as well was wondering about races between wait_on_page_writeback and readpage. the below fix just explains everything we've seen since not-fully-uptodate pages must have always bh on them and the below patch enforces just that invariant, and it should fix our pagecache-overwritten-by-disk-data problem.

That is, a ping from the PC never receives a response, and a ping from BlueZ never reaches the PC. Linux packet statistics show that the PC packets are received, but all return traffic seems to be routed over the loopback interface. Immediately after creating the BNEP connection with BlueZ, the Windows Bluetooth stack sends a BNEP_FILTER_NET_TYPE_SET_MSG with an effective length of zero. BlueZ interprets this message to mean that no filter ranges should be allowed. The code zeros the first entry in the filter list, which is than interpreted as meaning that no ranges of acceptable packets are available. This interpretation is wrong and leads to all packets being rejected by BNEP. The Bluetooth BNEP specification clearly states the following: The length (in octets) of this message is 4+4*N, where N is the number of disjoint ranges of Networking protocol types that form the complete set. Note that N=0 (empty set) denotes a reset to default filters (if any) supported by the remote device.

Problem is that with a large number of highmem LRU pages and a small number of lowmem LRU pages, the amount of pagecache scanning appears to be very small, so we don't push slab hard enough. The patch changes things so that for, say, a GFP_KERNEL allocation attempt we only consider ZONE_NORMAL and ZONE_DMA when calculating "what proportion of the LRU did the caller just scan". This will have the effect of shrinking slab harder in response to GFP_KERNEL allocations than for GFP_HIGHMEM allocations.

Since netlink_get_spi is meant to be a creation operation this is incorrect. The netlink_get_spi operation is modelled off the PFKEY SADB_GETSPI command which is specified in RFC 2367. The purpose of SADB_GETSPI is to create a new larval SA that can then be filled in by SADB_UPDATE. Its semantics does not allow two SADB_GETSPI calls to return the same SA, even if there is no SADB_UPDATE call in between. The reason the second netlink_get_spi is returning the same SA is because in find_acq(), the code is looking at all larval states as opposed to only larval states with an SPI of zero. Since the only other caller of find_acq() -- xfrm_state_add() intentionally ignores all return values with a non-zero SPI, it is safe to not look at SAs with non-zero SPIs at all in find_acq(). The following patch does exactly that. In fact, the find_acq() call in xfrm_state_add() is a remnant from the days when we had xfrm_state_replace() instead of xfrm_state_add() and xfrm_state_update(). It can now be safely removed. I'll post a separate patch for that. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S. Miller <davem@redhat.com> <herbert@gondor.apana.org.au> [IPSEC]: Remove redundant check in xfrm_state_add() This is the patch referred to in the netlink_get_spi thread. I was actually wrong about the reason for this patch though. Firstly it's the SPI check that is redundant and not the find_acq() call. And it's redundant because of the find_acq() patch, not because of the fact that this is in xfrm_state_add(). Now that find_acq() only returns SAs with SPIs, we don't need to check this in xfrm_state_add() anymore. We do still need the call though to clean up leftover larval states. Another side-effect of the change is that we can move the existence check above find_acq() since find_acq() will never return any SAs matching the SPI we're trying to add (It doesn't need to because if an SA with a matching SPI existed, it would've been returned by state_lookup() already).

I'm looking through the xfrm_alloc_spi stuff and noticed that the netlink alloc_spi function takes the range in host order while the PFKEY alloc_spi function takes them in network order. First I thought that I stuffed up since I was the one who changed the code in the netlink interface to take them in host order :) But reading RFC 2367 seems to indicate otherwise. It says that all fields are host order unless specified otherwise. And the spirange fields are not specified to be network order at all. Looking at the existing PFKEY users: User Space ---------- Openswan - Doesn't use PFKEY for this. Racoon - Puts zeros in there so it doesn't care. However its test-pfkey program stores things in host order. ISAKMPD - Stores things in host order. So the conclusion is that we can and should change our PFKEY implementation to use host order for these fields. This patch does exactly that.

This removes nearly all the SLB related code from arch/ppc64/kernel/stab.c and puts a rewritten version in arch/ppc64/mm, where it better belongs. The main SLB miss path is in assembler and the other routines have been cleaned up and streamlined. Notable changes: - Ugly bitfields no longer used for generating SLB entries. - slb_allocate() (the main SLB miss routine) is now in assembler, and all the data it uses is stored in the PACA. - The mm context is now copied into the PACA at context switch time, to avoid looking up the thread struct on SLB miss. - An SLB miss will now never (directly) result in a call to do_page_fault. If we get a miss on a totally bogus address the handler will now put in an SLB referencing VSID 0. This will never have any pages, so we'll get the (fatal) page fault shortly afterwards. This simplifies the SLB entry and exit paths. - The round-robin pointer in the PACA now references the last-used instead of next-to-use SLB slot, which simplifies the asm for updating it slightly. - Unify do_slb_bolted with the general SLB miss path. There is now one SLB miss handler, in assembler, and called with only the low-level exception prolog (EXCEPTION_PROLOG_[PI]SERIES rather than EXCEPTION_PROLOG_COMMON) and minimal extra save/restore logic. - Streamlines the exception entry/exit path of the SLB miss handler to shave a few cycles off. The most significant change is that the RI bit is left off throughout the whole handler, which avoids an extra mtmsrd to turn it back off on the exit path.

I just tracked down a nasty memory corruption problem where that was causing the bmac driver to try to process packets before the driver internal data structures were properly initialized. While I agree that the driver should (and will) be made more robust to such things, Paulus and I decided that it makes little sense to keep track of an "old" edge interrupt that happens before a driver does request_irq. (On those powermacs, those are only the DBDMA interrupts anyway, and none of the DBDMA users will care). This patch implements a "startup" handler for the old Apple PIC that will "ack" pending edge interrupts before unmasking, thus preventing those stale interrupts to be delivered.

Since journal_unmap_buffers trusts the buffer_jbd bit to see if we need to call __dispose_buffer, and nobody seems to test buffer_jbd after taking jbd_lock_bh_journal_head. The kernel dereferences a null jh pointer in __journal_remove_journal_head. The patch fixes this by using journal_grab_journal_head() in journal_unmap_buffer(). It ensures that we either grab and pin the journal_head if the bh has one, or we bale out if the bh doesn't have a journal_head.
