2.6.6-rc3 long-format changelog
Summary of changes from v2.6.6-rc2 to v2.6.6-rc3
============================================
<stevef@linux.local>
Can not mount from cifs vfs client built with gcc 3.3.1 due to
compiler optimization of unsafe global variable. Remove unsafe
global variable.
<stevef@linux.local>
Fix problem reconnecting additional mounts to the same server after
session failure.
<stevef@stevef95.austin.ibm.com>
Fix invalid dentry when race in mkdir between two clients
<stevef@linux.local>
fix oops in send_sig on unmount of cifs vfs due to sending signal
to demultiplex thread after it has exited.
Do not treat invalid handle warning in response to oplock break (of
file that is now closed) as an error.
<stevef@linux.local>
Fix EIO caused by network timeouts on changing file size.
To avoid spurious oplock breaks from server, in the case
of inodes that we already have open, avoid doing path
based setting of file size if we can do it by handle.
This keeps our caching token (oplock) and avoids
timeouts when the local oplock break takes longer to flush
writebehind data than the SMB timeout for the SetPathInfo
request would allow
<stevef@stevef95.austin.ibm.com>
fix to not retime out the same session twice since it can
invalidate the newly reestablished session unnecessarily
<stevef@smfhome.smfdom>
Do not return buffer if request has already timed out.
<stevef@stevef95.austin.ibm.com>
move bad smb session retry to correct location, up one level in
cifs vfs code
<stevef@steveft21.austin.ibm.com>
fix endian bug in lockingX and add retry on EAGAIN
<stevef@stevef95.austin.ibm.com>
have to reconnect open files safely, one at a time, as needed
<stevef@stevef95.austin.ibm.com>
finish off move from reopening all files on reconnection (which
takes too long under heavy stress) to reopen file as needed after
reconnection to server.
<stevef@stevef95.austin.ibm.com>
correct retry on remaining handles based calls
<stevef@steveft21.austin.ibm.com>
Fix compile error
<stevef@stevef95.austin.ibm.com>
Missing soft vs. hard retry mount option
<stevef@stevef95.austin.ibm.com>
Do not grab i_sem (already taken in filemap.c across commit write
calls) during reopen of invalidated file handle.
<stevef@linux-udp14619769uds.austin.ibm.com>
Fix oops in mount error path when unload_nls called with bad pointer.
<stevef@stevef95.austin.ibm.com>
Avoid smb data corruption under heavy stress
<stevef@stevef95.austin.ibm.com>
missing message on timed out requests
<stevef@stevef95.austin.ibm.com>
rcvtimeout set improperly for some cifs servers
<stevef@steveft21.ltcsamba>
invalidate locally cached pages when server breaks oplock. Do not
loop reconnecting for servers that drop tcp session rather than
sending smb negprot response
<stevef@steveft21.ltcsamba>
Oops on reopen files when dentry already freed
<stevef@steveft21.ltcsamba>
invalidate cached pages when last local instance closed so we do
not use stale data while someone may be modifying the file on the
server.
<stevef@steveft21.ltcsamba>
fix double incrementing of transaction counter
<stevef@steveft21.ltcsamba>
Fix check of filldir return code during readdir to avoid incomplete
search results displayed on very large directories. Fix cleanup of
proc entries. Add config parm to allow disabling negotiating Linux
extensions
<stevef@steveft21.ltcsamba>
allow disabling cifs Linux extensions via proc
<stevef@steveft21.ltcsamba>
Fix an incorrect mapping of open flags to cifs open disposition.
Fix blocking byte range locks. These fix breakages that were
notice running lock tests 1 and 7 of the connectathon posix file
api tests
<stevef@steveft21.ltcsamba>
set byte range locktimeouts properly
<stevef@steveft21.ltcsamba>
fix cifs readme
<stevef@stevef95.austin.ibm.com>
gracefully exit on failed mounts to win98 (which closes tcp session rather than erroring on smb protocol negotiation)
<stevef@stevef95.austin.ibm.com>
fix failed mounts to win98 part II
<stevef@stevef95.austin.ibm.com>
Fix global kernel name space pollution
<stevef@smfhome.smfdom>
Check return on failed dentry allocation. Suggested by Randy Dunlap
<stevef@steveft21.ltcsamba>
Allow null password string pointer and passwords longer than 16 bytes
<stevef@steveft21.ltcsamba>
finish handling commas in passwords
<stevef@steveft21.ltcsamba>
finish off mount parm sep override
<stevef@stevef95.austin.ibm.com>
Fix caching problem with multiply open files from different clients
<stevef@stevef95.austin.ibm.com>
Relax requested CIFS permissions on open to simply request
GENERIC_READ and GENERIC_WRITE (instead of GENERIC_ALL which
can unnecessarily conflict with share permissions by asking
implicitly for take ownership and other unneeded flags)
<stevef@stevef95.austin.ibm.com>
fix remoting caching part 2
<stevef@stevef95.austin.ibm.com>
remove spurious debug messages

<davej@redhat.com>
[CPUFREQ] Correcting SGTC. Timer is based upon FSB
From: Bruno Ducrot <ducrot@poupinou.org>
I think this patch is needed especially if the FSB is around 166MHz or
200MHz, or else I believe we get instabilities on some K7's motherboard
powernow capable (it's called Cool'n Quiet IIRC).
* Deduce fsb from cpu_khz and the max multiplier. It will be given as kHz now,
so that frequency associated to a multiplier will be computate more
accurately. Also, we need it for SGTC (see below).
* Fix how cpuid is computed in powernow_decode_bios().
* Be more restrictive for PST. It may be possible (on desktop shipped with
low power Athlon models) that FSB can be changed by dip switchs on
motherboard for example.
* Fix computation for SGTC. It use the bus timer (and then the bus
frequency given by fsb).
<davej@redhat.com>
[CPUFREQ] don't use speedstep-centrino on unsupported CPUs
From: Dominik Brodowski <linux@dominikbrodowski.de>
Don't use the ACPI data on CPUs we don't know nothing about.
<davej@redhat.com>
[CPUFREQ] powernow-k7 ACPI integration.
More from Bruno Ducrot.
Warning: it will only half work on the ACER Aspire, though: there is
no pstate in the DSDT corresponding to the max frequency...
I'm looking how to handle that correctly, probably at the init stage,
if the max frequency is not given, then add it to powernow_table.
* Integrate acpi perflib from Dominik.
* Use acpi if the PST tables are known to be broken (ASUS Aspire match one PST,
but give brain damaged values), or use ACPI if no PST found.
<davej@redhat.com>
[CPUFREQ] Drop unneeded part of last patch.
acpi fallback is handled already in the init function.
<davej@redhat.com>
[CPUFREQ] powernow-k7 needs to init later.
Due to the possible dependancy on ACPI.
<davej@redhat.com>
[CPUFREQ] Remove bogus newline in powernow-k7 driver.
<davej@redhat.com>
[CPUFREQ] Add a module parameter to force ACPI to be used.
<stevef@stevef95.austin.ibm.com>
Fix misc. minor memory leaks in error paths
<davej@redhat.com>
[CPUFREQ] Make powernow-k7 acpi debug output a little less verbose.
<davej@redhat.com>
[CPUFREQ] powernow-k7 ACPI->PST values were a factor of 10 off.
As much as I like the idea of a 13GHz laptop, setting it to 1.3GHz is probably
for the best for the time being.
<davej@redhat.com>
[CPUFREQ] clear defaults before powernow-k7 acpi fallback
Decoding the legacy tables may have set these values.
<stevef@stevef95.austin.ibm.com>
free cifs read buffer on retry
<stevef@stevef95.austin.ibm.com>
Fix major page leak in read code caused by extra page_cache_get call
<stevef@smfhome.smfdom>
check permission locally for servers that do not support the CIFS
Unix Extensions (allowing file_mode and dir_mode to augment the
server permission check, by doing local vfs_permission check)

[CPUFREQ] Not all powernow-K7 BIOS's put the frequency at MAX at POST.
<stevef@stevef95.austin.ibm.com>
Remove 64 bit compiler warning
<mbp@vexed.ozlabs.hp.com>
[PATCH] ia64: fpswa_interface needs to be exported
efivars can be built as a module, but it depends on 'fpswa_interface'
which is not exported by fpswa.c. Patch below fixes this problem.
<davej@redhat.com>
[CPUFREQ] Fix debug build of powernow-k8
From Paul Devriendt
<davej@redhat.com>
[CPUFREQ] Fix up missing CONFIG_X86_POWERNOW_K8_ACPI

<jakub@redhat.com>
[SPARC64]: Missing part of posix timers fix.
<drepper@redhat.com>
[PATCH] Add missing __initdata
One of the stack size optimizations introduced a new static variable in
a function marked with __init. But the variable is not marked
appropriately and so 1k of data is never freed.
<akpm@osdl.org>
[PATCH] Fix nfsroot option handling
From: Trond Myklebust <trond.myklebust@fys.uio.no>
The following patch fixes up a number of bugs in the NFSroot parser
rewrite from patchset
trond.myklebust@fys.uio.no|ChangeSet|20040411182341|00938
It also ensures that NFSroot mount options are consistent with the userland
"mount" program.
<akpm@osdl.org>
[PATCH] compute_creds race
From: Andy Lutomirski <luto@myrealbox.com>
Fixes from me, Olaf Dietsche <olaf+list.linux-kernel@olafdietsche.de>
In fs/exec.c, compute_creds does:
task_lock(current);
if (bprm->e_uid != current->uid || bprm->e_gid != current->gid) {
current->mm->dumpable = 0;
if (must_not_trace_exec(current)
|| atomic_read(¤t->fs->count) > 1
|| atomic_read(¤t->files->count) > 1
|| atomic_read(¤t->sighand->count) > 1) {
if(!capable(CAP_SETUID)) {
bprm->e_uid = current->uid;
bprm->e_gid = current->gid;
}
}
}
current->suid = current->euid = current->fsuid = bprm->e_uid;
current->sgid = current->egid = current->fsgid = bprm->e_gid;
task_unlock(current);
security_bprm_compute_creds(bprm);
I assume the task_lock is to prevent another process (on SMP or preempt)
from ptracing the execing process between the check and the assignment. If
that's the concern then the fact that the lock is dropped before the call
to security_brpm_compute_creds means that, if security_bprm_compute_creds
does anything interesting, there's a race.
For my (nearly complete) caps patch, I obviously need to fix this. But I
think it may be exploitable now. Suppose there are two processes, A (the
malicious code) and B (which uses exec). B starts out unprivileged (A and
B have, e.g., uid and euid = 500).
1. A ptraces B.
2. B calls exec on some setuid-root program.
3. in cap_bprm_set_security, B sets bprm->cap_permitted to the full
set.
4. B gets to compute_creds in exec.c, calls task_lock, and does not
change its uid.
5. B calls task_unlock.
6. A detaches from B (on preempt or SMP).
7. B gets to task_lock in cap_bprm_compute_creds, changes its
capabilities, and returns from compute_creds into load_elf_binary.
8. load_elf_binary calls create_elf_tables (line 852 in 2.6.5-mm1),
which calls cap_bprm_secureexec (through LSM), which returns false (!).
9. exec finishes.
The setuid program is now running with uid=euid=500 but full permitted
capabilities. There are two (or three) ways to effectively get local root
now:
1. IIRC, linux 2.4 doesn't check capabilities in ptrace, so A could
just ptrace B again.
2. LD_PRELOAD.
3. There are probably programs that will misbehave on their own under
these circumstances.
Is there some reason why this is not doable?
The patch renames bprm_compute_creds to bprm_apply_creds and moves all uid
logic into the hook, where the test and the resulting modification can both
happen under task_lock().
This way, out-of-tree LSMs will fail to compile instead of malfunctioning.
It should also make life easier for LSMs and will certainly make it easier
for me to finish the cap patch.
<akpm@osdl.org>
[PATCH] ext3 avoid writing kernel memory to disk
From: Marc-Christian Petersen <m.c.p@kernel.linux-systeme.com>
Solar Designer discovered an information leak in the ext3 code of Linux.
In a worst case an attacker could read sensitive data such as cryptographic
keys which would otherwise never hit disk media. Theodore Ts'o developed a
correction for this.
<akpm@osdl.org>
[PATCH] Call populate_rootfs later in boot
populate_rootfs() is called rather early - before we've called init_idle().
But populate_rootfs() does file I/O, which involves calls to cond_resched(),
and downing of semaphores, etc. If it scheules, the scheduler emits
scheduling-while-atomic warnings and sometimes oopses.
So run populate_rootfs() later, after the scheduler is all set up.
<akpm@osdl.org>
[PATCH] remove amd7xx_tco
From: Zwane Mwaikambo <zwane@linuxpower.ca>
We've had trouble with this driver, it appears to work but the hardware
never does the final reboot. I have yet to come across someone with a
board which works and don't have personal access to one. So how about
scrapping the whole thing.
<akpm@osdl.org>
[PATCH] lockfs - vfs bits
From: Christoph Hellwig <hch@lst.de>
These are the generic lockfs bits. Basically it takes the XFS freezing
statemachine into the VFS. It's all behind the kernel-doc documented
freeze_bdev and thaw_bdev interfaces.
Based on an older patch from Chris Mason.
<akpm@osdl.org>
[PATCH] lockfs: reiserfs fix
From: Chris Mason <mason@suse.com>
reiserfs_write_super_lockfs() is supposed to wait for the transaction to
commit.
<akpm@osdl.org>
[PATCH] lockfs - xfs bits
From: Christoph Hellwig <hch@lst.de>
Remove all the code now in the VFS, make XFS's freeze ioctls use the new
infastructure and reorganize some code.
This code needs some work so the source files shared with 2.4 aren't
exposed to the new VFS interfaces directly. You'll get an update once this
has been discussed with the other XFS developers and is implemented. Note
that the current patch works fine and I wouldn't complain if it gets into
Linus' tree as-is.
<akpm@osdl.org>
[PATCH] lockfs - dm bits
From: Christoph Hellwig <hch@lst.de>
This patch makes the device mapper use the new freeze_bdev/thaw_bdev
interface. Extracted from Chris Mason's patch.
<akpm@osdl.org>
[PATCH] i4l: add compat ioctl's for CAPI
From: Marcel Holtmann <marcel@holtmann.org>
This patch adds the needed compat ioctl's for the CAPI on 64bit platforms.
<akpm@osdl.org>
[PATCH] selinux: change context_to_sid handling for no-policy case
From: Stephen Smalley <sds@epoch.ncsc.mil>
This patch changes the behavior of security_context_to_sid in the no-policy
case so that it simply accepts all contexts and maps them to the kernel SID
rather than rejecting anything other than an initial SID. The change avoids
error conditions when using SELinux in permissive/no-policy mode, so that any
file contexts left on disk from prior use of SELinux with a policy will not
cause an error when they are looked up and userspace attempts to set contexts
can succeed.
<akpm@osdl.org>
[PATCH] selinux: add runtime disable
From: Stephen Smalley <sds@epoch.ncsc.mil>
This patch adds a kernel configuration option that enables writing to a new
selinuxfs node 'disable' that allows SELinux to be disabled at runtime prior
to initial policy load. SELinux will then remain disabled until next boot.
This option is similar to the selinux=0 boot parameter, but is to support
runtime disabling of SELinux, e.g. from /sbin/init, for portability across
platforms where boot parameters are difficult to employ (based on feedback by
Jeremy Katz).
<akpm@osdl.org>
[PATCH] selinux: remove hardcoded policy assumption from get_user_sids() logic
From: Stephen Smalley <sds@epoch.ncsc.mil>
This patch removes a hardcoded policy assumption from the get_user_sids logic
in the SELinux module that was preventing it from returning contexts that had
the same type as the caller even if the policy allowed such a transition. The
assumption is not valid for all policies, and can be handled via policy
configuration and userspace rather than hardcoding it in the module logic.
<akpm@osdl.org>
[PATCH] i810_dma range check
From: Andrea Arcangeli <andrea@suse.de>
Correctly range-check an incoming-from-userspace argument. Found by the
Stanford checker.
<akpm@osdl.org>
[PATCH] i386 hugetlb tlb correction
From: William Lee Irwin III <wli@holomorphy.com>
i386 does hardware interpretation of pagetables, so pte_clear() can't be
used on present ptes, as it sets the upper half of the hugepte prior to
setting the lower half (which includes the valid bit). i.e. there is a
window where having a hugepage mapped at 56GB and doing pte_clear() in
unmap_hugepage_range() allows other threads of the process to see a
hugepage at 0 in place of the original hugepage at 56GB.
This patch corrects the situation by using ptep_get_and_clear(), which
clears the lower word of the pte prior to clearing the upper word.
There is another nasty where huge_page_release() needs to wait for TLB
flushes before returning the hugepages to the free pool, analogous to the
issue tlb_remove_page() and tlb_flush_mm() repair.
<akpm@osdl.org>
[PATCH] loop_set_fd() sendfile check fix
From: Yury Umanets <torque@ukrpost.net>
I have found small inconsistency in loop_set_fd(). It checks if
->sendfile() is implemented for passed block device file. But in fact,
loop back device driver never calls it. It uses ->sendfile() from backing
store file.

[CPUFREQ] Make an educated guess at the current P-state in the ACPI driver.
One big limitation of the ACPI specification is that it's impossible to
detect the current P-State by reading from ACPI-defined registers. And the
CPU isn't always at P0 when the system boots. So, try to "guess" the current
P-State by analyzing cpu_khz.

[CPUFREQ] Fix security hole in proc handler.
Brad Spengler <spender@grsecurity.net> found an exploitable bug in the proc handler
of cpufreq, where a user-supplied unsigned int is cast to a signed int and then
passed on to copy_[to|from]_user() allowing arbitary amounts of memory to be written
(root only thankfully), or read (as any user).
The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned
the name CAN-2004-0228 to this issue.

From: Arthur Othieno <a.othieno@bluewin.ch>
<B.Zolnierkiewicz@elka.pw.edu.pl>
[PATCH] removal of MOD_{INC,DEC}_USE_COUNT in ide-cs.c
From: Pavel Roskin <proski@gnu.org>
The "ide-cs" module cannot be unloaded because it uses obsolete
MOD_INC_USE_COUNT and MOD_DEC_USE_COUNT macros. In fact, they are not
needed in ide-cs.c in 2.6 kernels. The generic PCMCIA code already
increases use count for every device served by the driver, so it's
impossible to unload the ide-cs driver while it's in use.
I was told that the removal of IDE interfaces may be unsafe in 2.6
kernels. However, MOD_INC_USE_COUNT only prevents removal of the module,
not the interface. It's also the first obstacle, albeit a trivial one,
for anybody debugging those problems (i.e. loading a modified module
requires "rmmod -f" or reboot to unload the old version).

[PATCH] atmel wireless update
Fixes to avoid problems when the driver shares an interrupt. These were
caused because the ISR cannot determine the status of the chip without
changing its state and the driver was only disabling the interrupts from
the card during some critical regions. An interrupt originating from
another device at the wrong moment could run the ISR and corrupt chip
state. Fixed by blocking interupts in the processor in critical regions
and never checking the chip interrupt status before the driver is fully
up.
Added the ability to override the Regulatory Domain stored in ROM. The
following command achieves this
iwpriv <interface> regdomain <domain>
vaild domains are USA,Canada,Europe,Spain,France,MKK,MKK1,Israel
The current regulatory domain affects which radio channels are available
for use.
Some minor tidying to calibrate busy-wait loops using udelay and remove
inclusion of obsolete include/linux/802_11.h

[PATCH] pcmcia netdev ordering fixes
From: Russell King <rmk+pcmcia@arm.linux.org.uk>
This is an *untested* patch (PCMCIA people, please test) to fix
initialisation ordering issues in these network device drivers. I don't
have the hardware to be able to test these changes, although it passes a
modular build without warnings.
Andrew - it may be worth sticking these in -mm so they get some visibility
via your tree as well.
Many of these drivers were calling register_netdev() before they had
completed their initialisation.
In addition, they were calling register_netdev with the
"DEV_CONFIG_PENDING" flag still set, which prevents hotplug scripts from
bringing up the interface.
Also, we take care to ensure that link->dev is correctly set - this is used
to tell the PCMCIA release code if the netdev is currently registered (yes,
that's probably racy at present, but lets sort one problem at a time.)
I've arranged that all drivers register the netdevice as close as possible
to the end of their initialisation, copy the net device's name for cardmgr
to pass to it's network scripts, and then print out whatever information
the driver wants to.
Finally, a note about ibmtr - it seemed to assume that cardmgr wanted "tr0"
or "tr1" depending on the base address, and completely ignoring the real
device which the netdev layer allocated it. I've assumed that this is
wrong (since the netdev name is used in printk messages), and changed it to
behave the same as the other drivers.

[PATCH] USB: Important bugfix for UHCI list management code
A major bug in the UHCI driver turned up recently. Thanks to a lot of
help from Simone Gotti it was identified and fixed late last week. It
turned out to be entirely my fault -- a previous patch had introduced two
(!) errors. (A combination of carelessness and a nasty thinko, and
somehow it passed the regression tests...)
Anyway, it's entirely possible that many of the problems people have been
seeing are caused by that bug. This patch is the solution.

[PATCH] symlink doesn't support kobj name > 20 charaters (KOBJ_NAME_LEN)
Since symlink.c uses "name" field of a kobj when it calculates the

instead of using kobj->name directly.

[PATCH] writeback livelock fix
If a filesystem's ->writepage implementation repeatedly refuses to write the

Fix that up by correctly setting wbc->pages_skipped, to tell the writeback
logic that things aren't working out.

[ARM PATCH] 1824/1: guard against gcc not respecting local variable register assignment
Patch from Nicolas Pitre
The recent discovery of a problem with gcc not always respecting register
assignment for local variables to be used with inline assembly is worrisome.
If unnoticed, such problems can cover bugs that might prove hard to find
especially when the code is right but silently ignored. This patch adds a
test where needed to have the assembler confirm our register selection and
fail the kernel build if the wrong registers are allocated.

[ARM PATCH] 1825/1: abort on bad code generation with div64 in some cases
Patch from Nicolas Pitre
One case was found when the kernel is compiled with -O2 (instead of the

this. Instead of blacklisting them all unconditionally, better just abort
when a bad case occurs especially since this bad case doesn't seem to
appear with current default compiler flags. Depends on patch #1824.

[ARM PATCH] 1815/1: Generic DMA buffer bouncing support for ARM targets
Patch from Deepak Saxena
Latest (and hopefully last :) patch for generic DMA buffer bouncing.
- Fixed SA1111 dma_needs_bounce
- Added check for out of bounds buffers.
- Made dmabounce.c directly implement dma_* API
Note that I didn't do the following:
#ifndef CONFIG_DMABOUNCE
inline implementations of all functions
#else
extern declarations
#endif
Instead I wrapped it individual in #ifndef/#else blocks to keep the
comments in the same area as function declarations. IMHO this makes
it easier for someone to go look at the comments if they need to know
what a specific API does.

[PATCH] don't log drive loading failures
This is an old bug that often confuses people, rightfully.
For some laptop and server type cdroms, the drives advertise themselves
as tray loading even if they are caddy-like or slot-in loaders. This
means they cannot insert the media on their own, and this generates a
5/24/00 error to START_STOP_UNIT.
This prevents the logging of such a failure, and also fixes the
generation of such a bad command in case the mech type was correctly set
by the drive.

[PATCH] ia64: bug w/ shared interrupts
I just ran into a bug introduced by the most recent iosapic.c patch.
The scenario is a builtin driver is up and running happily. A module
loads for a devices that happens to share the same interrupt vector,
in this case a network driver. The module calls pci_enable_device()
as it should, which eventually lands in iosapic_enable_intr(). We
then proceed to mask the interrupt and kill the device that's already
running. As a bonus, request_interrupt() doesn't fix the problem
because we only call the startup for the interrupt handler on the
first action attached to the interrupt.
I think the best way out of this is simply to detect when an action is
already attached to a vector and leave it alone. This also prevents
interrupts from moving to other cpus (on boxes w/o irq redirection)
for no good reason.

[PATCH] ia64: Remove SN PDA page overflow check
There's an obsolete check in sn_init_pdas() left over from the 2.4
days that panics if the cpu PDA and cpu_data area span more than a page.
With 2.6, we're not limited to a page, so remove the check entirely.

[TG3]: Fix jimbo frame PHY programming.
1. Added new workaround for 5705 to improve bit error rate.
2. Changed to use read-modify-write to set the extended packet bit in
tg3_phy_reset.
3. Removed some phy setup code in tg3_phy_probe. All of that is already
in the end of tg3_phy_reset. Writing to the phy during probe time may
contend with ASF because ASF is constantly reading phy registers to
determine the link.
4. Removed the write to phy register 0x18 in tg3_phy_copper_begin. Not
sure what it was for and it will overwrite that regsiter.

[PATCH] create singlethread_workqueue()
From: Rusty Russell <rusty@rustcorp.com.au>
Workqueues are a great primitive for running things from user context from
a completely clean environment. Unfortunately, they currently insist on
creating one thread per CPU, which is overkill for many situations, so the
more generic keventd workqueue is used for these. Recently deadlocks using
keventd were demonstrated, showing that it is not suitable for all uses.
1) Clean up CPU iterators. Always a nice touch.
2) Add __create_workqueue() and create_singlethread_workqueue(),
keeping source compatibility.
3) Put workqueues in workqueue list even if !CONFIG_HOTPLUG_CPU (means
we need a lock to protect that list). Now we can tell if a wq is
single-threaded using list_empty(&wq->list).
4) For single-threaded workqueues, override CPU in queue_work,
delayed_work_timer_fn and flush_workqueue to be 0. flush_workqueue
now does redundant passes for single-threaded workqueues, but the
code remains simple.
5) Make create_workqueue_thread return the thread, so we can easily
kthread_bind for multi-threaded workqueues.
akpm fixes:
- Fix up is_single_threaded() handling
- single-threaded wq thread does not have "/0" appended.

[PATCH] Use workqueue for call_usermodehelper
From: Rusty Russell <rusty@rustcorp.com.au>
call_usermodehelper uses keventd to create a thread, guaranteeing a nice,
clean kernel thread. Unfortunately, there is a case where
call_usermodehelper is called with &bus->subsys.rwsem held (via
bus_add_driver()), but keventd could be running bus_add_device(), which is
blocked on the same lock. The result is deadlock, and it comes from using
keventd for both.
In this case, it can be fixed by using a completely independent thread for
call_usermodehelper, or an independent workqueue. Workqueues have the
infrastructure we need, so we use one.
Move EXPORT_SYMBOL while we're there, too.
akpm fixes: Make it compile with !CONFIG_KMOD

[PATCH] credentials locking fix
From: Chris Wright <chrisw@osdl.org>
Contributions from:
Stephen Smalley <sds@epoch.ncsc.mil>
Andy Lutomirski <luto@stanford.edu>
During exec the LSM bprm_apply_creds() hooks may tranisition the program to a
new security context (like setuid binaries). The security context of the new
task is dependent on state such as if the task is being ptraced.
ptrace_detach() doesn't take the task_lock() when clearing task->ptrace. So
there is a race possible where a process starts off being ptraced, the
malicious ptracer detaches and if any checks agains task->ptrace are done more
than once, the results are indeterminate.
This patch ensures task_lock() is held while bprm_apply_creds() hooks are
called, keeping it safe against ptrace_attach() races. Additionally, tests
against task->ptrace (and ->fs->count, ->files->count and ->sighand->count all
of which signify potential unsafe resource sharing during a security context
transition) are done only once the results are passed down to hooks, making it
safe against ptrace_detach() races.
Additionally:
- s/must_must_not_trace_exec/unsafe_exec/
- move unsafe_exec() call above security_bprm_apply_creds() call rather than
in call for readability.
- fix dummy hook to honor the case where root is ptracing
- couple minor formatting/spelling fixes

[PATCH] ext3 journalled quota locking fix
From: Jan Kara <jack@ucw.cz>
I've attached a fix for a problem in ext3 journalled quota patch - the problem
is that detecting whether dqput() sleeps was wrong and so we could possibly
schedule when holding a spinlock.
<akpm@osdl.org>
[PATCH] Bigger quota hashtable
From: Jan Kara <jack@ucw.cz>
I found out that quota uses hash table with just 43 entries to hash dquot
entries. I guess that we can afford using one page for that
(quotactl(Q_GETQUOTA...), got faster like 3x for 4000 users). Attached patch
implements that.
<akpm@osdl.org>
[PATCH] Per-sb dquot dirty lists
From: Jan Kara <jack@ucw.cz>
When there are lots of dirty dquots the vfs_quota_sync() is too slow (it has
O(N^2) behaviour). Attached patch implements list of dirty dquots for each
superblock and quota type. Using this lists sync is trivially linear.
Attached patch is against 2.6.5 with journalled quota and previous patch for
hash table size.
(Jan had a test which went from 8 minutes to 0.8 seconds...)
<akpm@osdl.org>
[PATCH] dquot: remove unneeded test
We're testing the nullness of `sb' potentially after rereferencing it
(although the compiler will have reordered things to avoid such a bug).
Just remove the test - the superblock pointer shouldn't be null in there.

[PATCH] ppc64: Split prom.c Into pre-reloc and post-reloc Functions
From: Rusty Russell <rusty@rustcorp.com.au>
Move all the functions that run normally (ie. with the kernel in the correct
address) to the bottom of prom.c, and keep all the functions which use RELOC()
to the top, above "prom_init()" which calls them.
Also, make prom_initialize_dart_table and prom_initialize_tce_table static.

<akpm@osdl.org>
[PATCH] ppc64: Make finish_device_tree use lmb_alloc, not klimit
From: Rusty Russell <rusty@rustcorp.com.au>
finish_device_tree simply allocates nodes by incrementing klimit (ie. using
memory on top of the kernel). Change it to figure out how much memory it
needs, then use lmb_alloc to allocate that, then fill it in.
This gets rid of the only manipulation of klimit after prom_init.
<akpm@osdl.org>
[PATCH] ppc64: make_room macro for ppc64 prom.c
From: Rusty Russell <rusty@rustcorp.com.au>
copy_device_tree calls inspect_node() which recurses to copy the Open Firmware
device tree. It just copied into memory above the kernel for about 8MB, which
can overwrite the initrd, and/or get truncated on big machines.
The real solution is to allocate memory properly for all the prom_init memory
users. However, that's quite a change. This patch introduces a "make_room"
macro which inspect_node uses to get memory. This does the same as before,
except skips over the initrd if neccessary.

[PATCH] ppc64: Clean up prom functions in prom.c
From: Rusty Russell <rusty@rustcorp.com.au>
1) Define PROM_ERROR: checks for call_prom() < 0 are bogus (returns ulong)
2) All OF access functions should be marked __init.
3) prom_strtoul isn't used at all.
<akpm@osdl.org>
[PATCH] ppc64: Initrd Cleanup
From: Rusty Russell <rusty@rustcorp.com.au>
Clean up initrd handling.
1) Expose initrd_start and initrd_end to prom.c (replacing its local
initrd_start and initrd_len).
2) Don't hand mem (aka klimit) through functions which don't need it.
3) Add more debugging under DEBUG_PROM in case we broke anything.
<akpm@osdl.org>
[PATCH] ppc64: Move Initrd
From: Rusty Russell <rusty@rustcorp.com.au>
This patch moves the initrd when "make_room" runs out of space, rather than
stepping over it. The problem with stepping over it is that it gets copied
with the kernel when this happens, which wastes space.
Also ensures that the initrd isn't where the kernel wants to be moved to: if
it is, it gets moved out the way.
<akpm@osdl.org>
[PATCH] ppc64: prom.c fix for CONFIG_BLK_DEV_INITRD=n

[PATCH] slab alignment fixes
From: Manfred Spraul <manfred@colorfullife.com>
Below is a patch that redefines the kmem_cache_alloc `align' argument:
- align not zero: use the specified alignment. I think values smaller than
sizeof(void*) will work, even on archs with strict alignment requirement (or
at least: slab shouldn't crash. Obviously the user must handle the
alignment properly).
- align zero:
* debug on: align to sizeof(void*)
* debug off, SLAB_HWCACHE_ALIGN clear: align to sizeof(void*)
* debug off, SLAB_HWCACHE_ALIGN set: align to the smaller of
- cache_line_size()
- the object size, rounded up to the next power of two.
Slab never honored cache align for tiny objects: otherwise the 32-byte
kmalloc objects would use 128 byte objects.
There is one additional point: right now slab uses ints for the bufctls.
Using short would save two bytes for each object. Initially I had used short,
but davem objected. IIRC because some archs do not handle short efficiently.
Should I allow arch overrides for the bufctls? On i386, saving two bytes
might allow a few additional anon_vma objects in each page.

[PATCH] efivars: remove from arch/ia64
From: Matt Tolentino <metolent@snoqualmie.dp.intel.com>
I broke up the efivars driver update patch I had sent out quite a while ago
into several smaller patches. This includes several fixes and suggestions
that were pointed out. The patches are broken down as follows:
1 - remove all traces of efivars from arch/ia64/
2 - add new sysfs based efivars driver into
drivers/firmware with accompanying Kconfig/Makefile
changes to make it fully functional for ia64 again.
3 - cleans up x86 references to the /proc version of
the efivars driver.

[PATCH] efivars fixes
From: Matt Domsch <Matt_Domsch@dell.com>
Patch below fixes three small bugs in efivars.c as posted by Matt Tolentino
last week and included in the latest -mm. Aside from this small patch, I'm
quite pleased with Matt T's work, thanks!
- dummy() used for reading write-only sysfs files should return -ENODEV to
indicate failure, not 0.
- efivar_create() should return the number of bytes written on success, not
zero.
- efivar_delete() should return the number of bytes written on success, not
zero.

[PATCH] slab: use order 0 for vfs caches
We have interesting deadlocks when slab decides to use order-1 allocations for
ext3_inode_cache. This is because ext3_alloc_inode() needs to perform a
GFP_NOFS 1-order allocation.
Sometimes the 1-order allocation needs to free a huge number of pages (tens of
megabytes) before a 1-order grouping becomes available. But the GFP_NOFS
allocator cannot free dcache (and hence icache) due to the deadlock problems
identified in shrink_dcache_memory().
So change slab so that it will force 0-order allocations for shrinkable VFS
objects. We can handle those OK.

[PATCH] SELinux ptrace race fix
From: Stephen Smalley <sds@epoch.ncsc.mil>
Looking again at the SELinux ptrace check, I believe that there is an
unrelated race due to the fact that the parent link is only updated after
releasing the task lock in ptrace_attach (and this is necessary as task lock
doesn't nest with write lock of tasklist_lock).
The patch below changes SELinux to save the tracing process' SID upon a
successful selinux_ptrace hook call and then use that SID in the ptrace check
in apply_creds in order to avoid such races. This allows us to preserve the
fine-grained process-to-process ptrace check upon exec (vs. the global
CAP_SYS_PTRACE privilege => PT_PTRACE_CAP flag used by the capability module)
while still avoiding races.

[PATCH] kbuild: Improved external module support
From: Sam Ravnborg <sam@ravnborg.org>
The external module support recently introduced caused a number of problems:
- To build an external module the Module.symvers file was needed
- To create the Module.symvers file a module was required
- If Module.symvers was missing kbuild boiled out with an error
- If vmlinux was missing also the stage 2 of module build failed (make -k)
- It was not documented what was needed to actually bauild a module
The following patch addresses this by adding the following functionality:
- Always generate the Module.symvers file
- Ignore a missing Module.symvers file
- Add a new target modules_prepare, it prepares the kernel for building
external modules, and is also usefull with O=
- And it adds some more comments to Makefile.modpost, so others may follow
it with some luck
- .modpost.cmd is no longer generated
This should close all reports on issues with respect to building external
modules with current kernel - which has been identified as kernel problems.
