[PATCH] buffer: memorder fix
unlock_buffer(), like unlock_page(), must not clear the lock without
ensuring that the critical section is closed.
Mingming later sent the same patch, saying:
We are running SDET benchmark and saw double free issue for ext3 extended
attributes block, which complains the same xattr block already being freed (in
ext3_xattr_release_block()). The problem could also been triggered by
multiple threads loop untar/rm a kernel tree.
The race is caused by missing a memory barrier at unlock_buffer() before the
lock bit being cleared, resulting in possible concurrent h_refcounter update.
That causes a reference counter leak, then later leads to the double free that
we have seen.
Inside unlock_buffer(), there is a memory barrier is placed *after* the lock
bit is being cleared, however, there is no memory barrier *before* the bit is
cleared. On some arch the h_refcount update instruction and the clear bit
instruction could be reordered, thus leave the critical section re-entered.
The race is like this: For example, if the h_refcount is initialized as 1,
cpu 0: cpu1
-------------------------------------- -----------------------------------
lock_buffer() /* test_and_set_bit */
clear_buffer_locked(bh);
lock_buffer() /* test_and_set_bit */
h_refcount = h_refcount+1; /* = 2*/ h_refcount = h_refcount + 1; /*= 2 */
clear_buffer_locked(bh);
.... ......
We lost a h_refcount here. We need a memory barrier before the buffer head lock
bit being cleared to force the order of the two writes. Please apply.

[PATCH] extend the set of "__attribute__" shortcut macros
Extend the set of "__attribute__" shortcut macros, and remove identical
(and now superfluous) definitions from a couple of source files.
based on a page at robert love's blog:
http://rlove.org/log/
2005102601
extend the set of shortcut macros defined in compiler-gcc.h with the
following:
#define __packed __attribute__((packed))
#define __weak __attribute__((weak))
#define __naked __attribute__((naked))
#define __noreturn __attribute__((noreturn))
#define __pure __attribute__((pure))
#define __aligned(x) __attribute__((aligned(x)))
#define __printf(a,b) __attribute__((format(printf,a,b)))
Once these are in place, it's up to subsystem maintainers to decide if they
want to take advantage of them. there is already a strong precedent for
using shortcuts like this in the source tree.
The ones that might give people pause are "__aligned" and "__printf", but
shortcuts for both of those are already in use, and in some ways very
confusingly. note the two very different definitions for a macro named
"ALIGNED":
drivers/net/sgiseeq.c:#define ALIGNED(x) ((((unsigned long)(x)) + 0xf) & ~(0xf))
drivers/scsi/ultrastor.c:#define ALIGNED(x) __attribute__((aligned(x)))
also:
include/acpi/platform/acgcc.h:
#define ACPI_PRINTF_LIKE(c) __attribute__ ((__format__ (__printf__, c, c+1)))
Given the precedent, then, it seems logical to at least standardize on a
consistent set of these macros.

[PATCH] fix umask when noACL kernel meets extN tuned for ACLs
Fix insecure default behaviour reported by Tigran Aivazian: if an ext2 or
ext3 or ext4 filesystem is tuned to mount with "acl", but mounted by a
kernel built without ACL support, then umask was ignored when creating
inodes - though root or user has umask 022, touch creates files as 0666,
and mkdir creates directories as 0777.
This appears to have worked right until 2.6.11, when a fix to the default
mode on symlinks (always 0777) assumed VFS applies umask: which it does,
unless the mount is marked for ACLs; but ext[234] set MS_POSIXACL in
s_flags according to s_mount_opt set according to def_mount_opts.
We could revert to the 2.6.10 ext[234]_init_acl (adding an S_ISLNK test);
but other filesystems only set MS_POSIXACL when ACLs are configured. We
could fix this at another level; but it seems most robust to avoid setting
the s_mount_opt flag in the first place (at the expense of more ifdefs).
Likewise don't set the XATTR_USER flag when built without XATTR support.

[PATCH] RTC framework driver for CMOS RTCs
This is an "RTC framework" driver for the "CMOS" RTCs which are standard on
PCs and some other platforms. That's MC146818 compatible silicon.
Advantages of this vs. drivers/char/rtc.c (use one _or_ the other, only
one will be able to claim the RTC irq) include:
- This leverages both the new RTC framework and the driver model; both
PNPACPI and platform device modes are supported. (A separate patch
creates a platform device on PCs where PNPACPI isn't configured.)
- It supports common extensions like longer alarms. (A separate patch
exports that information from ACPI through platform_data.)
- Likewise, system wakeup events use "real driver model support", with
policy control via sysfs "wakeup" attributes and and using normal rtc
ioctls to manage wakeup. (Patch in the works. The ACPI hooks are
known; /proc/acpi/alarm can vanish. Making it work with EFI will
be a minor challenge to someone with e.g. a MiniMac.)
It's not yet been tested on non-x86 systems, without ACPI, or with HPET.
And the RTC framework will surely have teething pains on "mainstream"
PC-based systems (though must embedded Linux systems use it heavily), not
limited to sorting out the "/dev/rtc0" issue (udev easily tweaked). Also,
the ALSA rtctimer code doesn't use the new RTC API.
Otherwise, this should be a no-known-regressions replacement for the old
drivers/char/rtc.c driver, and should help the non-embedded distros (and
the new timekeeping code) start to switch to the framework.
Note also that any systems using "rtc-m48t86" are candidates to switch over
to this more functional driver; the platform data is different, and the way
bytes are read is different, but otherwise those chips should be compatible.

[PATCH] tty: improve encode_baud_rate logic
Mostly so people can see the work in progress. This enhances the encode
function which isn't currently used in the base tree but is when using some of
the testing tty patches.
This resolves a problem with some hardware where applications got confusing
information from the tty ioctls. Correct but confusing.
In some situations asking for, say, 9600 baud actually gets you 9595 baud or
similar near-miss values. With the old code this meant that a request for
B9600 got a return of BOTHER, 9595 which programs interpreted as a failure.
The new code now works on the following basis
- If you ask for specific rate via BOTHER, you get a precise return
- If you ask for a standard Bfoo rate and the result is close you get a Bfoo
return
- If you ask for a standard Bfoo rate and get something way off you get a
BOTHER/rate return
This seems to fix up the cases I've found where this broke compatibility.

The patch to identify AIX disks and ignore them has caused at least one
machine to fail to find the root partition on 2.6.19. The patch is:
http://lkml.org/lkml/2006/7/31/117
The problem is some disk formatters do not blow away the first 4 bytes
of the disk. If the disk we are installing to used to have AIX on it,
then the first 4 bytes will still have IBMA in EBCDIC.
The install in question was debian etch. Im not sure what the best fix
is, perhaps the AIX detection code could check more than the first 4
bytes.
The whole partition info for primary partitions is in this block:
dd if=/dev/sdb count=$(( 4 * 16 )) bs=1 skip=$(( 0x1be ))
All other data do not matter, beside the 0x55aa marker at the end of the

The wholesale move of the command receivers list into a new list was not
safe because the list will point to the new tail during a traversal, so the
traversal will never end on a reader if this happens during a read.
Memory barriers were needed to handle proper ordering of the setting of the
IPMI interface as valid. Readers might not see proper ordering of data
otherwise.
In ipmi_smi_watcher_register(), the use of the _rcu suffix on the list is
unnecessary.

[PATCH] use cycle_t instead of u64 in struct time_interpolator
The 32bit and 64bit PARISC Linux kernels suffers from the problem, that the
gettimeofday() call sometimes returns non-monotonic times.
The easiest way to fix this, is to drop the PARISC-specific implementation
and switch over to the generic TIME_INTERPOLATION framework.
But in order to make it even compile on 32bit PARISC, the patch below which
touches the generic Linux code, is mandatory.
More information and the full patch with the parisc-specific changes is included in this thread: http://lists.parisc-linux.org/pipermail/parisc-linux/2006-December/031003.html
As far as I could see, this patch does not change anything for the existing
architectures which use this framework (IA64 and SPARC64), since "cycles_t"
is defined there as unsigned 64bit-integer anyway (which then makes this
patch a no-change for them).

Because brd->info is not NULLed, resources are released twice. NULL it in

[PATCH] PNP: export pnp_bus_type
The PNP framework doesn't export "pnp_bus_type", which is an unfortunate
exception to the policy followed by pretty much every other bus. I noticed
this when I had to find a device in order to provide its platform_data.
Note that per advice from Arjan, the "export" scope has been been minimized to
avoid the hundred-plus bytes needed to support access from modules. In this
case, the symbol is only needed by statically linked kernel code that lives
outside the drivers/pnp directory.

[PATCH] ext2: skip pages past number of blocks in ext2_find_entry
This one was pointed out on the MOKB site:
http://kernelfun.blogspot.com/2006/11/mokb-09-11-2006-linux-26x-ext2checkpage.html
If a directory's i_size is corrupted, ext2_find_entry() will keep
processing pages until the i_size is reached, even if there are no more
blocks associated with the directory inode. This patch puts in some
minimal sanity-checking so that we don't keep checking pages (and issuing
errors) if we know there can be no more data to read, based on the block
count of the directory inode.
This is somewhat similar in approach to the ext3 patch I sent earlier this
year.

Mathieu originally needed to add this for tracing Xen, but it's something
that's needed for any application that can be tracing while cpus are added.
unplug isn't supported by this patch. The thought was that at minumum a new
buffer needs to be added when a cpu comes up, but it wasn't worth the effort
to remove buffers on cpu down since they'd be freed soon anyway when the
channel was closed.

The line discipline numbers N_* are currently defined for each architecture

architecture specific, nor any apparent relationship with the termios
structure. The total number of these, NR_LDISCS, is defined in linux/tty.h
anyway. So I propose the following patch which moves the definitions of
the individual line disciplines to linux/tty.h too.
Three of these numbers (N_MASC, N_PROFIBUS_FDL, and N_SMSBLOCK) are unused
in the current kernel, but the patch still keeps the complete set in case
there are plans to use them yet.
