2.6.8-rc2 long-format changelog
Summary of changes from v2.6.8-rc1 to v2.6.8-rc2
============================================ <wesolows@foobazco.org> [SPARC32]: Regenerate defconfig <wesolows@foobazco.org> [SPARC32]: Move non-PCI DMA definitions out of pgtable.h This also avoids a cyclic header inclusion problem with dma-mapping.h and linux/mm.h triggered by the recent change to standard DMA definitions. <wesolows@foobazco.org> [SPARC32]: Continue to avoid the use of __builtin_trap for BUG() gcc 3.3.3 continues to ICE on the BUG_ON() in mm/fremap.c. <wesolows@foobazco.org> [SPARC32]: Fix CONFIG_SUN4 build <shaggy@austin.ibm.com> JFS: Don't allow reading beyond the inode map's EOF If we try to read inodes that are beyond the size of the inode map, __read_metapages would read unitialized pages into the inode map's address space. If the inode map is later grown in order to allocate more inodes, the page is initialized and written under a different address space. Having the stale page in the page cache prevents the properly initialized page from being read, and results in errors. This problem can be provoked by an nfs client trying to read an inode that does not exist. Signed-off-by: Dave Kleikamp <shaggy@austin.ibm.com> <manfred@colorfullife.com> [PATCH] natsemi updates - support for external phys, both fibre and twisted pair, added: * remove the "phy" parameter from mdio_{read,write}: the function accesses the current phy. * new functions to access external phys: miiport_{read,write} * scan for external phys on _probe. * ethtool support for switching between internal and external phys. * introduce an init_phy_fixup helper: a few settings must be reapplied after reenabling the internal phy. - move register_netdev to the end of _probe. The current position could cause races with hotplug. - do not wait for autonegotiation completed after initialization. - use pci_name() instead of dev->name until register_netdev has initialized dev->name. - read the BMSR register in the link beat interrupt twice: The link status field is latched, without reading twice a link up event will be missed (and only noticed a few seconds later in the media timer) - restart the autonegotiation after modifying the capabilities. <akpm@osdl.org> [PATCH] sis900-fix-phy-transceiver-detection.patch From: Daniele Venzano <webvenza@libero.it> Fix PHY transceiver detection code to fall back to known PHY and not to the last detected. The code checks every transceiver detected for link status and type, but fails when ghost transceivers are detected, deciding to use the last one detected. With this patch the driver should choose the correct transceiver even when some ghosts are detected by checking for the type of the tranceiver it is going to use. <akpm@osdl.org> [PATCH] raw.c cleanups - pass the raw_config_request by reference, not by value. - fix whitespace drainbamage Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Greg Kroah-Hartman <greg@kroah.com> <greg@kroah.com> Driver Core: remove extra space in Kconfig file. Signed-off-by: Greg Kroah-Hartman <greg@kroah.com> <shaggy@austin.ibm.com> JFS: Error path released metadata page it shouldn't have Signed-off-by: Dave Kleikamp <shaggy@austin.ibm.com> <manfred@colorfullife.com> [PATCH] natsemi 1: switch to netdev_priv() <manfred@colorfullife.com> [PATCH] natsemi 2: support packets > 1518 bytes <manfred@colorfullife.com> [PATCH] Gigabit Ethernet support for forcedeth - Lots of updates for the gigabit ethernet nic: New ring entry format, support for RGMII phys, new pci ids. - Silence interrupt source 0x01: it's rx error, no need to ask the end user to report it. - add support for vlan packets: The NvRegOffloadConfig register contains the maximum packet size, it was set to 1518 which caused vlan to fail. - fix bit flags for mii access: the wrong bit was polled and the mii write implementation was just broken. - Do not stop the rx/tx engines around mii accesses. - reset and reinit the phy during probe. <shaggy@austin.ibm.com> JFS: Updated field isn't always written to disk during truncate There is a possibility that a change to header.next is not logged or written to disk if it is the only change to an xtree leaf page. Signed-off-by: Dave Kleikamp <shaggy@austin.ibm.com> <kaos@sgi.com> [PATCH] ia64: Rename local move_irq to sn_move_irq Rename SN local function move_irq to sn_move_irq to remove conflict with global move_irq. Needed since ashok.raj moved move_irq() from iosapic.c to irq.c. Signed-off-by: Keith Owens <kaos@sgi.com> Signed-off-by: David Mosberger <davidm@hpl.hp.com> <arun.sharma@intel.com> [PATCH] ia64: IA-32 sigaltstack bug fix More code needs to be guarded by if (uss32) { ... }. Without this patch, if (buf32..) may be checking uninitialized data and may result in spurious ENOMEMs. Signed-off-by: Gordon Jin <gordon.jin@intel.com> Signed-off-by: Arun Sharma <arun.sharma@intel.com> Signed-off-by: David Mosberger <davidm@hpl.hp.com> <kaos@sgi.com> [PATCH] ia64: Correct invalid unwind data ASM_UNW_PRLG_GRSAVE(n) must match the number of input registers in the following alloc statement. Otherwise you get invalid backtraces :( Signed-off-by: Keith Owens <kaos@sgi.com> Signed-off-by: David Mosberger <davidm@hpl.hp.com> <margitsw@t-online.de> [PATCH] prism54 freq to channel incorrect for 5GHz 2004-07-06 Margit Schubert-While <margitsw@t-online.de> * The frequency to channel conversion is wrong for the 5GHz band * Although the (known) devices don't/can't use it, they do report it. (iwlist ethX freq) <stevef@steveft21.ltcsamba> fix oops in build_wildcard_path_from_dentry <shaggy@austin.ibm.com> JFS: Protect active_ag with a spinlock Signed-off-by: Dave Kleikamp <shaggy@austin.ibm.com> <shaggy@austin.ibm.com> JFS: prevent concurrent calls to txCommit on the imap inode Signed-off-by: Dave Kleikamp <shaggy@austin.ibm.com> <kaber@trash.net> [NETFILTER]: Fix two broken checks for options in ipt_LOG Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: Harald Welte <laforge@netfilter.org> Signed-off-by: David S. Miller <davem@redhat.com> <shemminger@osdl.org> [NET]: Deinline sock_i_uid, sock_i_ino The sock_i_uid and sock_i_ino functions are only called by /proc type interfaces, so they don't need to be inlined. Also, the inline functions writeable, rcvtimeo, sndtimeo are test for value functions that don't change their argument. Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: David S. Miller <davem@redhat.com> <shaggy@austin.ibm.com> JFS: Check for dmap corruption before using leafidx Signed-off-by: Dave Kleikamp <shaggy@austin.ibm.com> <hirofumi@mail.parknet.co.jp> [IPV4]: IPMR fixes. - pim_protocol warning fix - ipmr_vif_open() and ipmr_mfc_open() allocates the memory, so it should use seq_release_private(). - ipmr_mfc_seq_xxx is using it->cache, in order to control whether unlock should be do or not, but it->cache was not initialized in ipmr_mfc_seq_start(). So it can point the previous state if user did seek(). This become to the cause of twice unlock. Signed-off-by: OGAWA Hirofumi <hirofumi@mail.parknet.co.jp> Signed-off-by: David S. Miller <davem@redhat.com> <hirofumi@mail.parknet.co.jp> [NET]: Cleanup mis-usage of seq_release_private These doesn't allocate memory and doesn't use seq->private. However kfree() ignores NULL, so these are not the problem. This patch just cleans these up. Signed-off-by: OGAWA Hirofumi <hirofumi@mail.parknet.co.jp> Signed-off-by: David S. Miller <davem@redhat.com> <peter@chubb.wattle.id.au> [PATCH] ia64: Fix OSDL BugMe report 2885: realtime process can't preempt low priority process in kernel Rearranged code to make it work. There were two problems: 1. The preempt flag was being tested only if code was leaving for user space (the logic should be: test for RESCHEDULE if we're switching to a kernel thread, test everything if switching to a user thread) 2. The check of the user space flags was being repeated even if the work had been done. There is one small change in semantics: when returning from a preemption, the preemption flag will *not* be rechecked. Otherwise, I found that it was easy to get into a livelock situation where no forward progress was made. Signed-off-by: David Mosberger <davidm@hpl.hp.com> <hadi@znyx.com> [PKT_SCHED]: Another missed tc_stats spinlock conversion. Signed-off-by: Jamal Hadi Salim <hadi@znyx.com> Signed-off-by: David S. Miller <davem@redhat.com> <davem@nuts.davemloft.net> [TCP]: Type qualifiers, such as const, are ignored on function return type. <jheffner@psc.edu> [TCP]: Do not round window to MSS if window scaling. Signed-off-by: John Heffner <jheffner@psc.edu> Signed-off-by: David S. Miller <davem@redhat.com> <davidm@tiger.hpl.hp.com> ia64: Nuke two compiler warnings. <alex@alexdalton.org> [PATCH] I2C: ADM1030 and Co sensors chips support Here is a patch against linux-2.6.7-mm1 kernel that adds support for adm1030 and adm1031 sensors chips. It has been reviewed several times by Jean Delvare, and he thinks it is ready for inclusion into 2.6 kernel. So here it is. Signed-off-by: Alexandre d'Alton <alex@alexdalton.org> Signed-off-by: Greg Kroah-Hartman <greg@kroah.com> <ebs@ebshome.net> [PATCH] I2C PPC4xx IIC driver: 0-length transactions bit-banging implementation IBM PPC 4xx i2c controller doesn't support 0-length transactions (e.g. used by SMBUS_QUICK). This patch implements bit-banging emulation for such requests and removes temporary kludge added earlier. Signed-off-by: Eugene Surovegin <ebs@ebshome.net> Signed-off-by: Greg Kroah-Hartman <greg@kroah.com> <khali@linux-fr.org> [PATCH] I2C: Class of scx200_acb This is needed for the scx200_acb to accept hardware monitoring chips. Signed-off-by: Jean Delvare <khali at linux-fr dot org> Signed-off-by: Greg Kroah-Hartman <greg@kroah.com> <khali@linux-fr.org> [PATCH] I2C: Add support for LM86, MAX6657 and MAX6658 to lm90 This adds support for the LM86, MAX6657 and MAX6658 sensor chips to the lm90 driver. These are less popular than the LM90 and ADM1032 but several users have reported to use these, so I added support to the lm90 driver. All these chips are fully compatible so that's just a matter of accepting the new chip ids. I also slightly simplified the detection code. Signed-off-by: Jean Delvare <khali at linux-fr dot org> Signed-off-by: Greg Kroah-Hartman <greg@kroah.com> <lcapitulino@prefeitura.sp.gov.br> [PATCH] I2C: i2c/i2c-dev.c::i2c_dev_init() cleanup. This patch does the fallowing cleanup for drivers/i2c/i2c-dev.c::i2c_dev_init(): *) in a error condition, return the error code of register_chrdev() insted of -EIO; *) adds missing audit for class_register(); *) in a error condition, only prints "Driver Initialisation Failed", insted printing the cause. (Note that the error will be printed by the return of the error code, and the information about what function caused the problem need to be done by a debug code). Only compiled, lack of hardware. Signed-off-by: Luiz Capitulino <lcapitulino@prefeitura.sp.gov.br> Signed-off-by: Greg Kroah-Hartman <greg@kroah.com> <khali@linux-fr.org> [PATCH] I2C: Documentation for i2c-parport At least, the i2c-parport gets some documentation. I heard several persons complaining that there was no sample electronics schema for building their own i2c-over-parallel-port, so I did just that, with the help of Sylvain Munaut. The documentation also includes the list of supported adapters, and a short comparison with other drivers using the parallel port to drive an i2c bus. At the end of the document I included an updated version of the i2c-velleman doc file (which I then deleted). Signed-off-by: Jean Delvare <khali at linux-fr dot org> Signed-off-by: Greg Kroah-Hartman <greg@kroah.com> <drewie@freemail.hu> [PATCH] I2C: Add support for LM77 This patch (against the current stack) adds support for the LM77 sensor chips made by National Semiconductor. Formerly this was claimed by the LM75 driver but when I got hold of an embedded board (built around the National Geode SC1100 CPU), which was equipped with an LM77, it turned out that the two chips are not compatible. It has been developed with help of, reviewed and approved by Jean Delvare. Signed-off-by: Andras Bali <drewie@freemail.hu> Signed-off-by: Greg Kroah-Hartman <greg@kroah.com> <bcasavan@sgi.com> [PATCH] ia64: Fix bug in ia64_atomic64_{add,sub} Hit this bug just yesterday. I hope the problem and fix require no explanation. Patched kernel boots and runs just fine. Signed-off-by: Brent Casavant <bcasavan@sgi.com> Signed-off-by: David Mosberger <davidm@hpl.hp.com> <davem@nuts.davemloft.net> [IPV4]: Fix multicast socket hangs. If a multicast packet gets looped back, the sending socket can hang if a local read just sits and does not empty its receive queue. The problem is that when an SKB clone is freed up, the destructor is only invoked for the head SKB when there is a fraglist (which is created for fragmentation). The solution is to account the fragment list SKB lengths in the top-level head SKB, then it all works out. Signed-off-by: David S. Miller <davem@redhat.com> <davidm@tiger.hpl.hp.com> ia64: Define machvec_noop as "static inline" This way, non-GENERIC kernels can optimize away the no-op calls while GENERIC kernels can still take the address of the function to initialize the machvec vector. <dtor_core@ameritech.net> [PATCH] Driver core: add platform_device_register_simple to register platform Add platform_device_register_simple to register platform devices requiring minimal resource and memory management. The device will have standard release function that just frees memory occupied by the platform device. By having release function in the driver core modules using such devices can be unloaded without waiting for the last reference to the device to be dropped. Signed-off-by: Dmitry Torokhov <dtor@mail.ru> Signed-off-by: Greg Kroah-Hartman <greg@kroah.com> <dtor_core@ameritech.net> [PATCH] Driver core: add default driver attributes to struct bus_type Signed-off-by: Dmitry Torokhov <dtor@mail.ru> Signed-off-by: Greg Kroah-Hartman <greg@kroah.com> <dtor_core@ameritech.net> [PATCH] Driver core: kset_find_obj should increment refcount of the found object kset_find_obj should increment refcount of the found object so users of the function can safely use returned object Signed-off-by: Dmitry Torokhov <dtor@mail.ru> Signed-off-by: Greg Kroah-Hartman <greg@kroah.com> <dtor_core@ameritech.net> [PATCH] Driver core: add driver_find helper to find a driver by its name Signed-off-by: Dmitry Torokhov <dtor@mail.ru> Signed-off-by: Greg Kroah-Hartman <greg@kroah.com> <eranian@hpl.hp.com> [PATCH] ia64: fix various problems in pfm_check_task_state() Commands not requiring the monitored task to be stopped would spin in wait_task_inactive() forever. After call to wait_task_inactive(), state may have changed, therefore it needs to be rechecked. Signed-off-by: Stephane Eranian <eranian@hpl.hp.com> Signed-off-by: David Mosberger <davidm@hpl.hp.com> <shaggy@austin.ibm.com> JFS: jfs_dmap build fix fs/jfs/jfs_dmap.c: In function `dbAllocNear': fs/jfs/jfs_dmap.c:1343: parse error before `*' fs/jfs/jfs_dmap.c:1357: `leaf' undeclared (first use in this function) fs/jfs/jfs_dmap.c:1357: (Each undeclared identifier is reported only once fs/jfs/jfs_dmap.c:1357: for each function it appears in.) Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Dave Kleikamp <shaggy@austin.ibm.com> <rohit.seth@intel.com> [PATCH] ia64: nointroute option needs to be parsed early This patch does an early parsing of kernel command line to check if no_int_route is present. Sal_init code depends on this option to enable/disable interrupt routing. Signed-off-by: Rohit Seth <rohit.seth@intel.com> Signed-off-by: David Mosberger <davidm@hpl.hp.com> <tony.luck@intel.com> [PATCH] ia64: allow module core code calls to module init code again Drop the prohibition for module core code calls to module init code (this breaks netfilter). Signed-off-by: <tony.luck@intel.com> Signed-off-by: David Mosberger <davidm@hpl.hp.com> <peterm@redhat.com> [PATCH] ia64: add audit support This patch adds IA64 support to the audit infrastructure. The IA64 audit patch complements the existing audit support for the i386, PPC64, and x86_64 architectures. This patch is based on work by Ray Lanza. Signed-off-by: Peter Martuccelli <peterm@redhat.com> Signed-off-by: David Mosberger <davidm@hpl.hp.com> <marcel@holtmann.org> [Bluetooth] Respond to L2CAP info requests This patch adds the correct behavior when a L2CAP info request is sent by the peer. The answer should be a L2CAP info response with the result code set to "not supported". Signed-off-by: Marcel Holtmann <marcel@holtmann.org> <kenneth.w.chen@intel.com> [PATCH] ia64: fix interpolation-bug in fsys_gettimeofday() The order of reading ar.itc is incorrect with respect to all other variables in fsys_gettimeofday. All variables involved in time interpolation need to be protected by the sequence lock xtime_lock for consistency check. However, the first time that fsys_gettimeofday() takes a time stamp, it reads the count outside the seq lock leading to the following possible time leap into the future scenario: fsys_gettimeofday: read ar.itc .... <context switch> .... read_seqbegin read all other variables (last_nsec_offset, jiffies, xtime) do time interpolation - elapsed_cycles become a large negative number and converting it to nsec overflows and make it a large positive number read_seqretry success updates last_nsec_offset (which is several seconds into the future). All subsequent gettimeofday() calls will be wrong as well because monotonic property kicks in. It only self-corrects once that future time actually arrives. This patch fixes the problem (and moves one instruction to make some room). Signed-off-by: Ken Chen <kenneth.w.chen@intel.com> Signed-off-by: Asit Mallick <asit.k.mallick@intel.com> Signed-off-by: David Mosberger <davidm@hpl.hp.com> <marcel@holtmann.org> [Bluetooth] Don't reset the USB halted bits The USB halted bits are useless and so there is no need to reset them after changing the configuration. Signed-off-by: Marcel Holtmann <marcel@holtmann.org> <khali@linux-fr.org> [PATCH] I2C: remove Documentation for i2c-pport > > This also raises a question about Documentation/i2c/i2c-pport. > > Should we keep a document about a driver which is not in the kernel > > tree (and hasn't even been ported to 2.6 yet)? > > No we should not. Signed-off-by: Jean Delvare <khali at linux-fr dot org> Signed-off-by: Greg Kroah-Hartman <greg@kroah.com> <khali@linux-fr.org> [PATCH] I2C: adm1025 driver ported to 2.6 This is my port of the adm1025 driver to 2.6. It has been tested by a few users and reported to work OK. Signed-off-by: Jean Delvare <khali at linux-fr dot org> Signed-off-by: Greg Kroah-Hartman <greg@kroah.com> <greg@kroah.com> I2C: sparse cleanups for a few i2c drivers. <alex@alexdalton.org> [PATCH] I2C: small ADM1030 fix Please find an incremental patch that applies on top of the previous one (the one from the first message of the thread) and that adds parenthesis to the macro as pointed out by Mark. Signed-off-by: Greg Kroah-Hartman <greg@kroah.com> <davem@nuts.davemloft.net> [PKT_SCHED]: Remove CSZ scheduler. It was an experimental hack and never finished off. Signed-off-by: David S. Miller <davem@redhat.com> <shemminger@osdl.org> [BRIDGE]: Support different MTU sizes. This patch adds support for different size MTU's to bridging. It is useful for bridging Ethernet's with jumbo frames, etc. The mtu of the bridge pseudo-device is maintained as the minimum of all the underlying ports. And when forwarding a frame through the bridge, it will drop the frame if the outgoing port's MTU is less than the frame size (as per 802 standard). Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: David S. Miller <davem@redhat.com> <greg@kroah.com> 1 Wire: add Dallas 1-wire protocol driver subsystem This was written and developed by Evgeniy Polyakov <johnpol@2ka.mipt.ru> with only very minor cleanups by me. Signed-off-by: Greg Kroah-Hartman <greg@kroah.com> <shemminger@osdl.org> [PKT_SCHED]: Add jitter support to netem. This patch adds jitter if desired to the delayed packets in the netem scheduler. I dropped the rate stuff out and reorganized so that an underlying pfifo queue is used (next plan is to make it have class ops). The jitter is given as sigma to a Gaussian normal distribution. The actual implementation is a reduced form of the table driven stuff in NISTnet (free). Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: David S. Miller <davem@redhat.com> <jmorris@redhat.com> [CRYPTO]: Remove lazy allocation from deflate. Signed-off-by: James Morris <jmorris@redhat.com> Signed-off-by: David S. Miller <davem@redhat.com> <herbert@gondor.apana.org.au> [XFRM]: Add FLUSHSA and FLUSHPOLICY. This patch adds FLUSHSA and FLUSHPOLICY to xfrm_user which are analagous to SADB_FLUSH and SADB_X_SPDFLUSH in af_key. This is useful in KMs on startup/shutdown so that the system is reset to a known state. 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]: Fix uh->len when doing NATT with IP options. I just noticed that the UDP header length in esp4_output() is incorrect when IP options are present (in transport mode). This patch fixes exactly that. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S. Miller <davem@redhat.com> <tomd@csds.uidaho.edu> [CRYPTO]: Set CRYPTO_TFM_RES_BAD_KEY_LEN in twofish. <davidm@tiger.hpl.hp.com> ia64: Fix EFI physical-mode stubs to correctly calculate physical address This fixes a bug in which the Ski simulator ended up getting the wrong time, since phys_get_time() ended up storing the correct time in the wrong place if a region-5 virtual address was passed (as would happen for stack variables of the init-task). On real machines, this bug likely would have caused a crash on machines which don't support switching EFI into virtual mode. <davidm@tiger.hpl.hp.com> ia64: Nuke a warning due to the syscall auditing patch. <herbert@gondor.apana.org.au> [IPSEC]: Move generic encap code into xfrm4_output I've finally finished merging the general encapsulation code for IPv4. Here is the patch. The idea is basically to make x->type->output similar in structure to x->type->input. That means moving the tunnel encapsulation and other generic code out. They have ended up in xfrm4_output.c. The advantage of this is that we have exactly one copy of the tunnel encapsulation code. So if we need to change it (e.g., set the TTL according to the route) then it's easier and less error-prone. In fact, in doing so I've already noticed that the ECN wasn't being copied correctly in everything except xfrm4_tunnel. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S. Miller <davem@redhat.com> <herbert@gondor.apana.org.au> [IPCOMP6]: Exclude IPCOMP header from props.header_len Now that the IPv4 encap stuff is out of the way, I'll be sending you the IPv6 versions. Here is the one to remove the unnecessary extra space reserved for IPCOMP.

Miller <davem@redhat.com> <gandalf@netfilter.org> [NETFILTER]: Add timestamping to ipt_ULOG After Andi's timestamp optimizations we don't have any timestamps on the packets unless someone requested them. Here's a patch for 2.6 to explicitly timestamp the packets before we log them. Harald approved it some time ago, he's pretty busy so I'm sending it instead. Signed-off-by: Martin Josefsson <gandalf@netfilter.org> Signed-off-by: David S. Miller <davem@redhat.com> <torvalds@ppc970.osdl.org> x86: fix stackframe ownership confusion in sys_sigaltstack() gcc doesn't understand that "asmlinkage" routines have the argument stack owned by the assembly-language caller, and the recent sparse cleanup made gcc think it owns enough stack frame space to make a tailcall by overwriting "struct pt_regs" that is set up by the low-level system call code. Hide that problem again. The real fix would be to tell gcc that the caller owns the stack frame that it set up, but we don't have any such interfaces, so for now the best we can do is to hide it. <wesolows@foobazco.org> [SPARC32]: Don't allow the kernel to read PAGE_NONE pages. <davem@nuts.davemloft.net> [SPARC64]: Update defconfig. <viro@www.linux.org.uk> [PATCH] sparse: NULL noise in fs/reiserfs <viro@www.linux.org.uk> [PATCH] sparse: misc NULL noise in fs/* <viro@www.linux.org.uk> [PATCH] sparse: aacraid annotation <viro@www.linux.org.uk> [PATCH] sparse: megaraid inline fixes inlined functions moved, a couple of heavy-weight ones (issue_scb() and meg_cmd_done()) uninlined. <viro@www.linux.org.uk> [PATCH] sparse: megaraid annotation <viro@www.linux.org.uk> [PATCH] sparse: NULL noise in drivers/isdn <viro@www.linux.org.uk> [PATCH] sparse: misc NULL noise in drivers/* <viro@www.linux.org.uk> [PATCH] sparse: ISDN ->readstat() and ->writecmd() annotation ->readstat() and ->writecmd() are always getting a userland pointer; marked argument as such, killed "user" flag, killed dead code. <viro@www.linux.org.uk> [PATCH] sparse: blind dereference of userland pointers in divasproc <viro@www.linux.org.uk> [PATCH] sparse: drivers/isdn/* annotation <viro@www.linux.org.uk> [PATCH] sparse: dvb_ringbuffer_pkt_write()/dvb_ringbuffer_write() annotation copy_from_user() moved from dvb_ringbuffer_{write,pkt_write}() to callers; these functions are always getting kernel pointer now.

However, the device can be renamed - then on teardown it tries to remove the wrong directory. The removal of /proc/driver/aironet then runs afoul of the BUG_ON() in remove_proc_entry. This fixes it by keeping a copy of the name of the directory it created. (It doesn't actually solve the problem of the stats directory still being /proc/driver/aironet/eth0 when you rename the device to, say, 'joe'. But that patch would be a little less trivial.)

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.

Detection of VBUS power is the first step in enumeration, and usually corresponds to a device being plugged into a hub. * "Soft Connect" feature, wherein the D+ pullup is under gadget driver control. 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. (The OTG spec requires user interfaces to report this stuff.) Say if this is a B-Peripheral or an A-Peripheral. * Says that usb_gadget_wakeup() is how to access SRP, and usb_gadget_disconnect() is how to access HNP. - Minor updates/cleanups to comments (Linux 2.5-->2.6 etc) Currently there's no support for SRP-only OTG devices.

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.

Following patch removes all those eight (six in netfilter, one net driver and one SCSI driver). <daniel@osdl.org> [PATCH] mmap PROT_NONE fix for NX patch This works around the current PROT_NONE problem from elf binaries that do not have the PT_GNU_STACK so that the do not have execute permission. The problem was that setting "def_flags" to include the VM_EXEC bit for compatibility reasons would also make PROT_NONE pages executable, which is obviously not correct.

They take kvec/length of kvec as separate arguments, do set_fs(), stick kvec into msghdr and call sock_...msg(). The next group of patches will switch network filesystems to use of kvec for kernel data + use of these helpers.

In this state dirty pages are not written back in sync() or from kupdate, only from direct page reclaim. And this causes a livelock in balance_dirty_pages after a while. The actual sequence of events required to get into this state is: thread function inode state inode list ---------------------------------------------------------------------------- 1 __sync_single_inode (background) I_DIRTY sb->s_io 1 do_writepages ...

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. Fix is to check the correct location and don't zero it afterwards because it gets reinitialized for the next CPU anyways. Thanks to Alexander Nyberg for tracking it down. <ak@muc.de> [PATCH] Fix i386 bootup with HIGHMEM+SLAB_DEBUG+NUMA and no real For some reason I booted a NUMA and SLAB_DEBUG i386 kernel on a non NUMA 512MB machine. This caused an oops at bootup in change_page_attr. 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. Fix is straightforward: if there is no highmem set highmem_start_page to max_low_pfn+1 <torvalds@ppc970.osdl.org> Clean up ptrace child exit case. This also fixes it for when the real parent is ignoring SIGCHLD - noted by David Mosberger. <torvalds@ppc970.osdl.org> Linux 2.6.8-rc2 Ready for the kernel summit in Ottawa...
