10 years agovmalloc: remove BUG_ON due to racy counting of VM_LAZY_FREE
Yongseok Koh [Tue, 19 Jan 2010 08:33:49 +0000]
vmalloc: remove BUG_ON due to racy counting of VM_LAZY_FREE

In free_unmap_area_noflush(), va->flags is marked as VM_LAZY_FREE first, and
then vmap_lazy_nr is increased atomically.

But, in __purge_vmap_area_lazy(), while traversing of vmap_are_list, nr
is counted by checking VM_LAZY_FREE is set to va->flags.  After counting
the variable nr, kernel reads vmap_lazy_nr atomically and checks a
BUG_ON condition whether nr is greater than vmap_lazy_nr to prevent
vmap_lazy_nr from being negative.

The problem is that, if interrupted right after marking VM_LAZY_FREE,
increment of vmap_lazy_nr can be delayed.  Consequently, BUG_ON
condition can be met because nr is counted more than vmap_lazy_nr.

It is highly probable when vmalloc/vfree are called frequently.  This
scenario have been verified by adding delay between marking VM_LAZY_FREE
and increasing vmap_lazy_nr in free_unmap_area_noflush().

Even the vmap_lazy_nr is for checking high watermark, it never be the
strict watermark.  Although the BUG_ON condition is to prevent
vmap_lazy_nr from being negative, vmap_lazy_nr is signed variable.  So,
it could go down to negative value temporarily.

Consequently, removing the BUG_ON condition is proper.

A possible BUG_ON message is like the below.

Len Brown [Wed, 20 Jan 2010 04:10:04 +0000]
ACPI: allow C3 > 1000usec

Do for C3 what the previous patch did for C2.

The C2 patch was in response to a highly visible
and multiply reported C-state/turbo failure,
while this change has no bug report in-hand.

This will enable C3 in Linux on systems where BIOS
overstates C3 latency in _CST.  It will also enable
future systems which may actually have C3 > 1000usec.

Linux has always ignored ACPI BIOS C3 with exit latency > 1000 usec,
and the ACPI spec is clear that is correct FADT-supplied C3.

However, the ACPI spec explicitly states that _CST-supplied C-states
have no latency limits.

So move the 1000usec C3 test out of the code shared
by FADT and _CST code-paths, and into the FADT-specific path.

ACPI: enable C2 and Turbo-mode on Nehalem notebooks on A/C

Linux has always ignored ACPI BIOS C2 with exit latency > 100 usec,
and the ACPI spec is clear that is correct FADT-supplied C2.

However, the ACPI spec explicitly states that _CST-supplied C-states

So move the 100usec C2 test out of the code shared

This bug has not been visible until Nehalem, which advertises
a CPU-C2 worst case exit latency on servers of 205usec.
That (incorrect) figure is being used by BIOS writers
on mobile Nehalem systems for the AC configuration.
Thus, Linux ignores C2 leaving just C1, which is
saves less power, and also impacts performance
by preventing the use of turbo mode.

ACPI: processor: restrict early _PDC to opt-in platforms

Commit 78f1699 (ACPI: processor: call _PDC early) blindly walks
the namespace and calls _PDC on every processor object it finds.

This change may cause issues on platforms that declare dummy
values for SSDTs on non-present processors (disabled in MADT).
When we call _PDC and dynamically attempt to execute the AML
Load() op on these dummy SSDTs, there's no telling what might
happen.

Rather than finding every platform that has bogus SSDTs, restrict
early _PDC calls to platforms that are known to need early
evaluation of _PDC.

This is a minimal, temporary fix (given the context of the
current release cycle). A real solution of checking the MADT for
non-present processors will be written for the next merge window.

10 years agoeCryptfs: Add getattr function
Tyler Hicks [Wed, 4 Nov 2009 08:48:01 +0000]
eCryptfs: Add getattr function

The i_blocks field of an eCryptfs inode cannot be trusted, but
generic_fillattr() uses it to instantiate the blocks field of a stat()
syscall when a filesystem doesn't implement its own getattr().  Users
have noticed that the output of du is incorrect on newly created files.

This patch creates ecryptfs_getattr() which calls into the lower
filesystem's getattr() so that eCryptfs can use its kstat.blocks value
after calling generic_fillattr().  It is important to note that the
block count includes the eCryptfs metadata stored in the beginning of
the lower file plus any padding used to fill an extent before
encryption.

10 years agoeCryptfs: Use notify_change for truncating lower inodes
Tyler Hicks [Wed, 14 Oct 2009 21:18:27 +0000]
eCryptfs: Use notify_change for truncating lower inodes

When truncating inodes in the lower filesystem, eCryptfs directly
invoked vmtruncate(). As Christoph Hellwig pointed out, vmtruncate() is
a filesystem helper function, but filesystems may need to do more than
just a call to vmtruncate().

This patch moves the lower inode truncation out of ecryptfs_truncate()
and renames the function to truncate_upper().  truncate_upper() updates
an iattr for the lower inode to indicate if the lower inode needs to be
truncated upon return.  ecryptfs_setattr() then calls notify_change(),
using the updated iattr for the lower inode, to complete the truncation.

For eCryptfs functions needing to truncate, ecryptfs_truncate() is
reintroduced as a simple way to truncate the upper inode to a specified
size and then truncate the lower inode accordingly.

The comments in arm_machine_restart() suggest that cpu_proc_fin()

This also makes kexec work for v7. Note that a related TLB and

"crc error".

Note that there are still some issues that seem to be related

ARM: 5883/1: Revert "disable NX support for OABI-supporting kernels"

This reverts commit 14f0aa359365e8a93a77b71e3b840274b9b4dcb1.

That commit was needed earlier because system call restarting for
OABI (compat) required an executable stack and thus had problems
with NX.  Since ab72b00734ae4d0b ("ARM: Fix signal restart issues
with NX and OABI compat") has reworked the code to not require an

ALSA: Remove warning message for invalid OSS minor ranges

When a card instance with a higher card number is registered, warning
messages are spewed eventually with stack traces due to the invalid minor
number for OSS device registration.  For example, thinkpad-acpi registers
the card number 29 as default, and you'll see always these messages.
This is rather confusing (and worries users), thus better to return
simply the error code.

ARM: 5882/1: ARM: Fix uncompress code compile for different defines of flush(void)

Because of the include of the decompress_inflate.c file from
boot/compress/misc.c, there are different flush() defines:

In file included from arch/arm/boot/compressed/misc.c:249:
arch/arm/boot/compressed/../../../../lib/decompress_inflate.c:138:29: error: macro "flush" passed 2 arguments, but takes just 0

Fix this by removing the define of flush() in misc.c for
CONFIG_DEBUG_ICEDCC as it's already defined in mach/uncompress.h,
and that is being included unconditionally.

Also use a static inline function instead of define
for mach-mxc and mach-gemini to avoid similar bug
for those platforms.

Btrfs: fix possible panic on unmount

We can race with the unmount of an fs and the stopping of a kthread where we
will free the block group before we're done using it.  The reason for this is
because we do not hold a reference on the block group while its caching, since
the allocator drops its reference once it exits or moves on to the next block
group.  This patch fixes the problem by taking a reference to the block group
before we start caching and dropping it when we're done to make sure all
accesses to the block group are safe.  Thanks,

Btrfs: fix regression in orphan cleanup

Currently orphan cleanup only ever gets triggered if we cross subvolumes during
a lookup, which means that if we just mount a plain jane fs that has orphans in
it, they will never get cleaned up.  This results in panic's like these

http://www.kerneloops.org/oops.php?number=1109085

where adding an orphan entry results in -EEXIST being returned and we panic.  In
order to fix this, we check to see on lookup if our root has had the orphan
cleanup done, and if not go ahead and do it.  This is easily reproduceable by
running this testcase

#include <sys/types.h>
#include <sys/stat.h>
#include <fcntl.h>
#include <string.h>
#include <unistd.h>
#include <stdio.h>

int main(int argc, char **argv)
{
char data[4096];
char newdata[4096];
int fd1, fd2;

memset(data, 'a', 4096);
memset(newdata, 'b', 4096);

while (1) {
int i;

fd1 = creat("file1", 0666);
if (fd1 < 0)
break;

for (i = 0; i < 512; i++)
write(fd1, data, 4096);

fsync(fd1);
close(fd1);

fd2 = creat("file2", 0666);
if (fd2 < 0)
break;

ftruncate(fd2, 4096 * 512);

for (i = 0; i < 512; i++)
write(fd2, newdata, 4096);
close(fd2);

i = rename("file2", "file1");
unlink("file1");
}

return 0;
}

and then pulling the power on the box, and then trying to run that test again
when the box comes back up.  I've tested this locally and it fixes the problem.

missing. This is however not due to passing a large value to filldir,

10 years agomodpost: fix segfault in sym_is() with prefixed arches
Mike Frysinger [Sat, 16 Jan 2010 21:57:34 +0000]
modpost: fix segfault in sym_is() with prefixed arches

The sym_is() compares a symbol in an attempt to automatically skip symbol
prefixes.  It does this first by searching the real symbol with the normal
unprefixed symbol.  But then it uses the length of the original symbol to
check the end of the substring instead of the length of the symbol it is
looking for.  On non-prefixed arches, this is effectively the same thing,
so there is no problem.  On prefixed-arches, since this is exceeds by just
one byte, a crash is rare and it is usually a NUL byte anyways.  But every
once in a blue moon, you get the right page alignment and it segfaults.

For example, on the Blackfin arch, sym_is() will be called with the real
symbol "___mod_usb_device_table" as "symbol" when looking for the normal
symbol "__mod_usb_device_table" as "name".  The substring will thus return
one byte into "symbol" and store it into "match".  But then "match" will
be indexed with the length of "symbol" instead of "name" and so we will
exceed the storage.  i.e. the code ends up doing:
char foo[] = "abc"; return foo[strlen(foo)+1] == '\0';
