commit f3f80a9205da74fa56d613f4c14b88b6e4e6caa8 upstream.
The snd-usb-caiaq driver causes Oops occasionally when accessing MIDI
devices. This patch fixes the Oops and invalid URB submission errors
as well.

From: Jonathan Brassow <[email protected]>
commit d460c65a6a9ec9e0d284864ec3a9a2d1b73f0e43 upstream.
Always increase the error count when I/O on a leg of a mirror fails.
The error count is used to decide whether to select an alternative
mirror leg. If the target doesn't use the "handle_errors" feature, the
error count is not updated and the bio can get requeued forever by the
read callback.
Fix it by increasing error_count before the handle_errors feature
checking.

commit 7b574b7b0124ed344911f5d581e9bc2d83bbeb19 upstream.
The race is calling cgroup_clone() while umounting the ns cgroup subsys,
and thus cgroup_clone() might access invalid cgroup_fs, or kill_sb() is
called after cgroup_clone() created a new dir in it.
The BUG I triggered is BUG_ON(root->number_of_cgroups != 1);

In the multiple device case we need to re-arm the completion and protect
against concurrent self-tests. The printk from the test callback is
removed as it can arbitrarily delay completion of the test.

commit a2ed9615e3222645007fc19991aedf30eed3ecfd
fixed a bug with 'internal' bitmaps, but in the process broke
'in a file' bitmaps. So they are broken in 2.6.28
This fixes it, and needs to go in 2.6.28-stable.

From: Serge E. Hallyn <[email protected]>
commit 0b82ac37b889ec881b645860da3775118effb3ca upstream.
The devcgroup_inode_permission() hook in the devices whitelist cgroup has
always bypassed access checks on fifos. But the mknod hook did not. The
devices whitelist is only about block and char devices, and fifos can't
even be added to the whitelist, so fifos can't be created at all except by
tasks which have 'a' in their whitelist (meaning they have access to all
devices).
Fix the behavior by bypassing access checks to mkfifo.

2.6.27-stable review patch. If anyone has any objections, please let us know.
------------------
From: Zhu Yi <[email protected]>
commit f1bc4ac61f2c08515afd80c6dc3962aa6d0b138b upstream.
Previously we allocate Rx SKB with GFP_ATOMIC flag. This is because we need
to hold a spinlock to protect the two rx_used and rx_free lists operation
in the rxq.
spin_lock();
...
element = rxq->rx_used.next;
element->skb = alloc_skb(..., GFP_ATOMIC);
list_del(element);
list_add_tail(&element->list, &rxq->rx_free);
...
spin_unlock();
After spliting the rx_used delete and rx_free insert into two operations,
we don't require the skb allocation in an atomic context any more (the
function itself is scheduled in a workqueue).
spin_lock();
...
element = rxq->rx_used.next;
list_del(element);
...
spin_unlock();
...
element->skb = alloc_skb(..., GFP_KERNEL);
...
spin_lock()
...
list_add_tail(&element->list, &rxq->rx_free);
...
spin_unlock();
This patch should fix the "iwlagn: Can not allocate SKB buffers" warning
we see recently.

ca7e716: Revert "sched_clock: prevent scd->clock from moving backwards"
... this time with resume restoring GTOD later in the sequence
taken into account as well.
The "timekeeping_suspended" flag is not very nice but we cannot call into
GTOD before it has been properly resumed and the scheduler will run very
early in the resume sequence.

From: Ravikiran G Thirumalai <[email protected]>
commit 26799a63110dcbe81291ea53178f6b4810d07424 upstream.
The pda rework (commit 3461b0af025251bbc6b3d56c821c6ac2de6f7209)
to remove static boot cpu pdas introduced a performance bug.
_boot_cpu_pda is the actual pda used by the boot cpu and is definitely
not "__read_mostly" and ended up polluting the read mostly section with
writes. This bug caused regression of about 8-10% on certain syscall
intensive workloads.

From: Cliff Wickman <[email protected]>
commit 46814dded1b972a07b1609d81632eef3009fbb10 upstream.
Impact: fix crash on x86/UV
UV is the SGI "UltraViolet" machine, which is x86_64 based.
BAU is the "Broadcast Assist Unit", used for TLB shootdown in UV.
This patch removes the allocation and initialization of an unused table.
This table is left over from a development test mode. It is unused in
the present code.
And it was incorrectly initialized: 8 entries allocated but 17 initialized,
causing slab corruption.
This patch should go into 2.6.27 and 2.6.28 as well as the current tree.
Diffed against 2.6.28 (linux-next, 12/30/08)

From: Michael Kerrisk <[email protected]>
commit 4ae8978cf92a96257cd8998a49e781be83571d64 upstream.
The problems lie in the types used for some inotify interfaces, both at the kernel level and at the glibc level. This mail addresses the kernel problem. I will follow up with some suggestions for glibc changes.
For the sys_inotify_rm_watch() interface, the type of the 'wd' argument is
currently 'u32', it should be '__s32' . That is Robert's suggestion, and
is consistent with the other declarations of watch descriptors in the
kernel source, in particular, the inotify_event structure in
include/linux/inotify.h:
struct inotify_event {
__s32 wd; /* watch descriptor */
__u32 mask; /* watch mask */
__u32 cookie; /* cookie to synchronize two events */
__u32 len; /* length (including nulls) of name */
char name[0]; /* stub for possible name */
};
The patch makes the changes needed for inotify_rm_watch().

From: Heiko Carstens <[email protected]>
commit 2ed7c03ec17779afb4fcfa3b8c61df61bd4879ba upstream.
Convert all system calls to return a long. This should be a NOP since all
converted types should have the same size anyway.
With the exception of sys_exit_group which returned void. But that doesn't
matter since the system call doesn't return.

From: Heiko Carstens <[email protected]>
commit 1134723e96f6e2abcf8bfd7a2d1c96fcc323ef35 upstream.
Remove __attribute__((weak)) from common code sys_pipe implemantation.
IA64, ALPHA, SUPERH (32bit) and SPARC (32bit) have own implemantations
with the same name. Just rename them.
For sys_pipe2 there is no architecture specific implementation.

From: Heiko Carstens <[email protected]>
commit c9da9f2129d6a421c32e334a83770a9e67f7feac upstream.
Not a single architecture has wired up sys_pselect7 plus it is the
only system call with seven parameters. Just make it static and
rename it to do_pselect which will do the work for sys_pselect6.

From: Heiko Carstens <[email protected]>
commit 1a94bc34768e463a93cb3751819709ab0ea80a01 upstream.
From: Martin Schwidefsky <[email protected]>
By selecting HAVE_SYSCALL_WRAPPERS architectures can activate
system call wrappers in order to sign extend system call arguments.
All architectures where the ABI defines that the caller of a function
has to perform sign extension probably need this.

------------------
From: Heiko Carstens <[email protected]>
commit 6673e0c3fbeaed2cd08e2fd4a4aa97382d6fedb0 upstream.
System calls with an unsigned long long argument can't be converted with
the standard wrappers since that would include a cast to long, which in
turn means that we would lose the upper 32 bit on 32 bit architectures.
Also semctl can't use the standard wrapper since it has a 'union'
parameter.
So we handle them as special case and add some extra wrappers instead.

commit eb7c3adb1ca92450870dbb0d347fc986cd5e2af4 upstream.
Some users reported that they have machines with BMCs enabled that cannot
receive IPMI traffic after e1000e is loaded.
http://marc.info/?l=e1000-devel&m=121909039127414&w=2
http://marc.info/?l=e1000-devel&m=121365543823387&w=2
This fixes the issue if they load with the new parameter = 0 by disabling
crc stripping, but leaves the performance feature on for most users.
Based on work done by Hong Zhang.

The result from readlink is being used to index into the link name
buffer without checking whether it is a valid length. If readlink

From: Nick Piggin <[email protected]>
commit 54566b2c1594c2326a645a3551f9d989f7ba3c5e upstream.
With the write_begin/write_end aops, page_symlink was broken because it
could no longer pass a GFP_NOFS type mask into the point where the
allocations happened. They are done in write_begin, which would always
assume that the filesystem can be entered from reclaim. This bug could
cause filesystem deadlocks.
The funny thing with having a gfp_t mask there is that it doesn't really
allow the caller to arbitrarily tinker with the context in which it can be
called. It couldn't ever be GFP_ATOMIC, for example, because it needs to
take the page lock. The only thing any callers care about is __GFP_FS
anyway, so turn that into a single flag.
Add a new flag for write_begin, AOP_FLAG_NOFS. Filesystems can now act on
this flag in their write_begin function. Change __grab_cache_page to
accept a nofs argument as well, to honour that flag (while we're there,
change the name to grab_cache_page_write_begin which is more instructive
and does away with random leading underscores).
This is really a more flexible way to go in the end anyway -- if a
filesystem happens to want any extra allocations aside from the pagecache
ones in ints write_begin function, it may now use GFP_KERNEL (rather than
GFP_NOFS) for common case allocations (eg. ocfs2_alloc_write_ctxt, for a
random example).

------------------
From: Nick Piggin <[email protected]>
commit e8c82c2e23e3527e0c9dc195e432c16784d270fa upstream.
An XFS workload showed up a bug in the lockless pagecache patch. Basically it
would go into an "infinite" loop, although it would sometimes be able to break
out of the loop! The reason is a missing compiler barrier in the "increment
reference count unless it was zero" case of the lockless pagecache protocol in
the gang lookup functions.
This would cause the compiler to use a cached value of struct page pointer to
retry the operation with, rather than reload it. So the page might have been
removed from pagecache and freed (refcount==0) but the lookup would not correctly
notice the page is no longer in pagecache, and keep attempting to increment the
refcount and failing, until the page gets reallocated for something else. This
isn't a data corruption because the condition will be detected if the page has
been reallocated. However it can result in a lockup.
Linus points out that ACCESS_ONCE is also required in that pointer load, even
if it's absence is not causing a bug on our particular build. The most general
way to solve this is just to put an rcu_dereference in radix_tree_deref_slot.

From: Wu Fengguang <[email protected]>
commit 136221fc3219b3805c48db5da065e8e3467175d4 upstream.
aops->readpages() and its NFS helper readpage_async_filler() will only
be called to do readahead I/O for newly allocated pages. So it's not
necessary to test for the always 0 dirty/uptodate page flags.
The removal of nfs_wb_page() call also fixes a readahead bug: the NFS
readahead has been synchronous since 2.6.23, because that call will
clear PG_readahead, which is the reminder for asynchronous readahead.
More background: the PG_readahead page flag is shared with PG_reclaim,
one for read path and the other for write path. clear_page_dirty_for_io()
unconditionally clears PG_readahead to prevent possible readahead residuals,
assuming itself to be always called in the write path. However, NFS is one
and the only exception in that it _always_ calls clear_page_dirty_for_io()
in the read path, i.e. for readpages()/readpage().

I increased the delay step by step until loading of mvsas
reliably detected the drive 200 times in sequence. A much better
approach would be to monitor the hardware for some flag which
indicates that port detection has finished, but I do not have any
hardware documentation.

commit 18e6959c385f3edf3991fa6662a53dac4eb10d5b upstream.
This assertion is incorrect for lockless pagecache. By definition if we
have an unpinned page that we are trying to take a speculative reference
to, it may become the tail of a compound page at any time (if it is
freed, then reallocated as a compound page).
It was still a valid assertion for the vmscan.c LRU isolation case, but
it doesn't seem incredibly helpful... if somebody wants it, they can
put it back directly where it applies in the vmscan code.

commit 2218108e182fd8a6d9106077833ed7ad05fc8e75 upstream.
When running Active Memory Sharing, the Collaborative Memory Manager
(CMM) may mark some pages as "loaned" with the hypervisor.
Periodically, the CMM will query the hypervisor for a loan request,
which is a single signed value. When kexec'ing into a kdump kernel,
the CMM driver in the kdump kernel is not aware of the pages the
previous kernel had marked as "loaned", so the hypervisor and the CMM
driver are out of sync. This results in the CMM driver getting a
negative loan request, which can then get treated as a large unsigned
value and can cause kdump to hang due to the CMM driver inflating too
large. Since there really is no clean way for the CMM driver in the
kdump kernel to clean this up, simply disable CMM in the kdump kernel.
This fixes hangs we were seeing doing kdump with AMS.

While doing various error injection testing, such as cable
pulls and target moves, some issues were observed in handling
these events. This patch improves the way these events are handled
by increasing the delay waiting for the fabric to settle and also
changes the behavior of Link Up to break the CRQ to ensure everything
gets cleaned up properly on the VIOS.

I have another Argosy USB storage device, which has the same problem
with the Argosy USB storage device already fixed in 2.6.27.7. But this
device has another product ID (840:84), so this patch adds a new entry
into unusual_devs to fix the mount problem.
I enclose here two patches: one against 2.6.27.8, and another against
the latest linus-git tree.

commit b8d23491f127aa0cd1863bd6cb58e771c558b762 upstream.
This patch corrects the issue when one connects a Nokia 5200 cell
phone in data storage mode. If one uses an unpatched unusual_devs.h,
the following messages appear on /var/log/messages:

The MicroSD card in the phone remains inaccessible and finally the
cell phone turns itself off. The patch solves this problem and makes
the cell phone fully accessible:

I've found necessary to use the FL_US_CAPACITY_FIX switch, as without
it the cell phone is recognized but it went berserk when performing
low-level functions on it (a fdisk -l /dev/uba for example).

From: Andi Kleen <[email protected]>
commit f313e12308f7c5ea645f18e759d104d088b18615 upstream.
Ajith Kumar noticed:
I was going through the vmalloc fault handling for x86_64 and am unclear
about the following lines in the vmalloc_fault() function.
pgd = pgd_offset(current->mm ?: &init_mm, address);
pgd_ref = pgd_offset_k(address);
Here the intention is to get the pgd corresponding to the current process
and sync it up with the pgd in init_mm(obtained from pgd_offset_k).
However, for kernel threads current->mm is NULL and hence pgd =
pgd_offset(init_mm, address) = pgd_ref which means the fault handler
returns without setting the pgd entry in the MM structure in the context
of which the kernel thread has faulted. This could lead to never-ending
faults and busy looping of kernel threads like pdflush. So, shouldn't the
pgd = pgd_offset(current->mm ?: &init_mm, address); be pgd =
pgd_offset(current->active_mm ?: &init_mm, address);
We can use active_mm unconditionally because it should be always set.

commit 1c41fa8288277e76785acb50f52bb2f39509f903 upstream.
Adds a delay prior to retrying a failed NPIV login. This fixes
a scenario if the backing fibre channel adapter is getting reset
due to an EEH event, NPIV login will fail. Currently, ibmvfc
retries three times very quickly, resets the CRQ and tries one
more time. If the adapter is getting reset due to EEH, this isn't
enough time. This adds a delay prior to retrying a failed NPIV
login and also increments the number of retries.

From: Suresh Siddha <[email protected]>
commit 0b8fdcbcd287a1fbe66817491e6149841ae25705 upstream.
Don't use large pages for kernel identity mapping with DEBUG_PAGEALLOC.
This will remove the need to split the large page for the
allocated kernel page in the interrupt context.
This will simplify cpa code(as we don't do the split any more from the
interrupt context). cpa code simplication in the subsequent patches.

2.6.27-stable review patch. If anyone has any objections, please let us know.
------------------
From: Rafael J. Wysocki <[email protected]>
commit 355a72d75b3b4f4877db4c9070c798238028ecb5 upstream.
Rework the handling of suspend and resume of PCI devices which have
no drivers or the drivers of which do not provide any suspend-resume
callbacks in such a way that their standard PCI configuration
registers will be saved and restored with interrupts disabled. This
should prevent such devices, including PCI bridges, from being
resumed too late to be able to function correctly during the resume
of the other PCI devices that may depend on them.
Also, to remove one possible source of future confusion, drop the
default handling of suspend and resume for PCI devices with drivers
providing the 'pm' object introduced by the new suspend-resume
framework (there are no such PCI drivers at the moment).
This patch addresses the regression from 2.6.26 tracked as
http://bugzilla.kernel.org/show_bug.cgi?id=12121 .

From: Rafael J. Wysocki <[email protected]>
commit 90d25f246ddefbb743764f8d45ae97e545a6ee86 upstream
I don't see why the suspend and resume of PCI Express ports should be
handled with interrupts enabled and it may even lead to problems in
some situations. For this reason, move the suspending and resuming
of PCI Express ports into ->suspend_late() and ->resume_early()
callbacks executed with interrupts disabled.
This patch addresses the regression from 2.6.26 tracked as
http://bugzilla.kernel.org/show_bug.cgi?id=12121 .

From: Rafael J. Wysocki <[email protected]>
commit a79d682f789730dfabaebbb507c87a90c0671a62 upstream
Suspend-resume of PCI Express ports has recently been moved into
_suspend_late() and _resume_early() callbacks, but some functions
executed from there should not be called with interrupts disabled,
eg. pci_enable_device(). For this reason, split the suspend-resume
of PCI Express ports into parts to be executed with interrupts
disabled and with interrupts enabled.

From: Rafael J. Wysocki <[email protected]>
commit 63f4898ace2788a89ed685672aab092e1c3e50e6 upstream.
Since interrupts will soon be disabled at PCI resume time, we need to
pre-allocate memory to save/restore PCI config space (or use GFP_ATOMIC,
but this is safer).

And this one? Is GFP_KERNEL ok, or 0?

Hmm, we don't support at least gcc 3.4.6 anymore :/. It seems to be the same as in:
http://lkml.org/lkml/2007/12/6/385
It doesn't like inline prototypes.

{sigh} I knew I would mess something up...
It is there now, give it 10 minutes or so to replicate out to the public

I think flags is right. That way, a caller of pagecache_write_begin (eg. page_symlink)
can instruct it with AOP_FLAG_NOFS to prevent grab_cache_page from doing a GFP_KERNEL
allocation.

This should be 0. grab_cache_page_write_begin takes write_begin aop flags rather
than regular gfp flags (it's a bit confusing, sorry :P). 0 ~= GFP_KERNEL (wheras
AOP_FLAG_NOFS ~= GFP_NOFS). So you have the right idea ;)

why not:
movq (%rsp), %rsi
instead? Yes, it's all the same but 0 is just unnecessary.

I supposed in light of the previous verison having "8" it's to be a bit
more explicit :)

Compiles fine for me on s390 with gcc 3.4.6 on git head.
Could you send the .config please?

Hi,
it's not matter of .config. It's matter of compiler. I can't reproduce it on my
own, I just know, that Dave had problems with inline prototypes and using of the
function they declare before the body itself was available with some gcc 3.4.6.
Dave, don't you remember where did you get the compiler from and what was the
platform?

I see two possible quick fixes:
-funit-at-a-time will allow these inline constructs (tested with 3.4.6 on i386
with enabled syscall wrappers. x86_64 already sets this flag)
- dont use attribute __always_inline__ for these inlines but the standard
inline. The question is, how to convince cpp to not replace inline with
always_inline

To be consistent with the rest of the file. Feel free to post a cleanup patch
for the whole file to see what maintainers think ;).

If that helps: care to send a patch that enables this?
Dependent on CONFIG_HAVE_SYSCALL_WRAPPERS?
That is, if this is really a problem.

I could do that, but...
> That is, if this is really a problem.
..I dont know if this is really a problem. i386 is the only architecture where
I was able to reproduce the inline problem. But i386 does not set
SYSCALL_WRAPPERS so the problem goes away.
I suggest to wait for a patch until we know of an architecture that is
affected (inline problem + HAVE_SYSCALL_WRAPPERS set).

I'll go fix this up and release a -rc2 with the fix in it.

I've put up a 2.6.27.12-rc2 release, fixing one thing, at:
kernel.org/pub/linux/kernel/v2.6/stable-review/patch-2.6.27.12-rc2.gz

It was discussed off-list with Linus, Andrew and all arch maintainers.
