[ Upstream commit 74a61ebf ] The SKY2_HW_RAM_BUFFER bit in hw->flags was checked in sky2_mac_init(), before being set later in sky2_up(). Setting SKY2_HW_RAM_BUFFER in sky2_init() where other hw->flags are set should avoid this problem recurring.

[ Upstream commit ec475623 ] Usbnet framework assumes USB hardware doesn't handle zero length packets, but SMSC LAN95xx requires these to be sent for correct operation. This patch fixes an easily reproducible tx lockup when sending a frame that results in exactly 512 bytes in a USB transmission (e.g. a UDP frame with 458 data bytes, due to IP headers and our USB headers). It adds an extra flag to usbnet for the hardware driver to indicate that it can handle and requires the zero length packets. This patch should not affect other usbnet users, please also consider for -stable. Signed-off-by: Steve Glendinning <steve.glendinning@smsc.com> Signed-off-by: David S.

[ Upstream commit 657e9649 ] I have recently came across a preemption imbalance detected by: <4>huh, entered ffffffff80644630 with preempt_count 00000102, exited with 00000101? <0>------------[ cut here ]------------ <2>kernel BUG at /usr/src/linux/kernel/timer.c:664! <0>invalid opcode: 0000 [1] PREEMPT SMP with ffffffff80644630 being inet_twdr_hangman(). This appeared after I enabled CONFIG_TCP_MD5SIG and played with it a bit, so I looked at what might have caused it. One thing that struck me as strange is tcp_twsk_destructor(), as it calls tcp_put_md5sig_pool() -- which entails a put_cpu(), causing the detected imbalance. Found on 2.6.23.9, but 2.6.31 is affected as well, as far as I can tell. Signed-off-by: Robert Varga <nite@hq.alert.sk> Signed-off-by: David S.

[ Upstream commit 8ba69ba6 ] Kalle Olavi Niemitalo reported that: "..., when one process calls sendmsg once to send 43804 bytes of data and one file descriptor, and another process then calls recvmsg three times to receive the 16032+16032+11740 bytes, each of those recvmsg calls returns the file descriptor in the ancillary data. I confirmed this with strace. The behaviour differs from Linux 2.6.26, where reportedly only one of those recvmsg calls (I think the first one) returned the file descriptor." This bug was introduced by a patch from me titled "net: unix: fix inflight counting bug in garbage collector", commit 6209344f. And the reason is, quoting Kalle: "Before your patch, unix_attach_fds() would set scm->fp = NULL, so that if the loop in unix_stream_sendmsg() ran multiple iterations, it could not call unix_attach_fds() again. But now, unix_attach_fds() leaves scm->fp unchanged, and I think this causes it to be called multiple times and duplicate the same file descriptors to each struct sk_buff." Fix this by introducing a flag that is cleared at the start and set when the fds attached to the first buffer. The resulting code should work equivalently to the one on 2.6.26.

commit 14f03343 upstream. The message "ACPI: Device needs an ACPI driver" is misleading. The device _may_ need an ACPI driver, if the BIOS implemented a custom API for the device in question (which, AFAIK, can't be checked.) If not, then either a generic ACPI driver may be used (for example "thermal"), or nothing can be done (other than a white list). I propose to reword the message to: ACPI: If an ACPI driver is available for this device, you should use it instead of the native driver which I think is more correct. Comments and suggestions welcome. I also added a message warning about possible problems and system instability when users pass acpi_enforce_resources=lax, as suggested by Len.

Resolved differently upstream in commit 8cab02dc Ondrej Zary reported a suspend/resume hang with 2.6.31 in bug #14222. http://bugzilla.kernel.org/show_bug.cgi?id=14222 The hang was bisected to c7121843 however, that was really just the last straw that caused the issue. The problem was that on suspend, the PIT is removed as a clocksource, and was using the mult value essentially as a is_enabled() flag. The mult adjustments done in the commit above caused that usage to break, causing bad list manipulation and the oops. Further, on resume, the PIT clocksource is never restored, causing the system to run in a degraded mode with jiffies as the clocksource. This issue has since been resolved in 2.6.32-rc by commit 8cab02dc which removes the clocksource disabling on suspend. Testing shows no issues there. So the following patch rectifies the situation for 2.6.31 users of the PIT clocksource that use suspend and resume (which is probably not that many). Many thanks to Ondrej for helping narrow down what was happening, what caused it, and verifying the fix. --------------- Avoid using the unprotected clocksource.mult value as an "is_registered" flag, instead us an explicit flag variable. This avoids possible list corruption if the clocksource is double-unregistered. Also re-register the PIT clocksource on resume so folks don't have to use jiffies after suspend.

commit e13ee546 upstream. Clear prefetch setting before potentially (re-)enabling it in config_drive_art_rwp() so the transition of the device type on the port from ATA to ATAPI (i.e. during warm-plug operation) is handled correctly. This is a really old bug (it probably goes back to very early days of the driver) but it was only affecting warm-plug operation until the recent "ide: try to use PIO Mode 0 during probe if possible" change (commit 60293364).

commit 31a56396 upstream. After commit 355cfa73 ("mm: modify swap_map and add SWAP_HAS_CACHE flag"), read_swap_cache_async() will busy-wait while a entry doesn't exist in swap cache but it has SWAP_HAS_CACHE flag. Such entries can exist on add/delete path of swap cache. On add path, add_to_swap_cache() is called soon after SWAP_HAS_CACHE flag is set, and on delete path, swapcache_free() will be called (SWAP_HAS_CACHE flag is cleared) soon after __delete_from_swap_cache() is called. So, the busy-wait works well in most cases. But this mechanism can cause soft lockup if add_to_swap_cache() sleeps and read_swap_cache_async() tries to swap-in the same entry on the same cpu. This patch calls radix_tree_preload() before swapcache_prepare() and divides add_to_swap_cache() into two part: radix_tree_preload() part and radix_tree_insert() part(define it as __add_to_swap_cache()).

commit 2fb930b5 upstream. The "VIA DXS" controls are actually volume controls that apply to the four PCM substreams, so we better indicate this connection by moving the controls to the PCM interface. Commit b452e08e in 2.6.30 broke the restoring of these volumes by "alsactl restore" that most distributions use; the renaming in this patch cures that regression by preventing alsactl from applying the old, wrong volume levels to the new controls. http://bugzilla.kernel.org/show_bug.cgi?id=14151 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=532613Signed-off-by: Clemens Ladisch <clemens@ladisch.de> Signed-off-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

commit 3b761d3d upstream. While trying to work around spurious detection retries for non-existent devices on slave links, commit 816ab897 incorrectly added link offline check logic before ata_eh_thaw() was called. This means that if an occupied link goes down briefly at the time that offline check was performed, device class will be cleared to ATA_DEV_NONE and libata wouldn't retry thus failing detection of the device. The offline check should be done after the port is thawed together with online check so that such link glitches can be detected by the interrupt handler and handled properly.

commit fdc6f192 upstream. Commit f2e21c96 had unfortunate side effects with cpufreq governors on some systems. If the system did not switch into NOHZ mode ts->inidle is not set when tick_nohz_stop_sched_tick() is called from the idle routine. Therefor all subsequent calls from irq_exit() to tick_nohz_stop_sched_tick() fail to call tick_nohz_start_idle(). This results in bogus idle accounting information which is passed to cpufreq governors. Set the inidle flag unconditionally of the NOHZ active state to keep the idle time accounting correct in any case.

commit eaaea803 upstream.

The risk of corruption is minimal, but still it is incorrect to keep the pointers valid. Actually glibc should uninstall the robust list before calling exec() but we have to deal with it anyway.

Linus Torvalds authored
commit 0b5759c6 upstream. A couple of people have hit the WARN_ON() in drivers/char/tty_io.c, tty_open() that is unhappy about seeing the tty line discipline go away during the tty hangup. See for example http://bugzilla.kernel.org/show_bug.cgi?id=14255 and the reason is that we do the tty_ldisc_halt() outside the ldisc_mutex in order to be able to flush the scheduled work without a deadlock with vhangup_work. However, it turns out that we can solve this particular case by - using "cancel_delayed_work_sync()" in tty_ldisc_halt(), which waits for just the particular work, rather than synchronizing with any random outstanding pending work. This won't deadlock, since the buf.work we synchronize with doesn't care about the ldisc_mutex, it just flushes the tty ldisc buffers. - realize that for this particular case, we don't need to wait for any hangup work, because we are inside the hangup codepaths ourselves. so as a result we can just drop the flush_scheduled_work() entirely, and then move the tty_ldisc_halt() call to inside the mutex. That way we never expose the partially torn down ldisc state to tty_open(), and hold the ldisc_mutex over the whole sequence.

commit 415e4993 upstream. For devices using OTP memory, EEPROM image can start from any one of the OTP blocks. If shadow RAM is disabled, we need to traverse link list to find the last valid block, then start the EEPROM image reading. If OTP is not full, the valid block is the block _before_ the last block on the link list; the last block on the link list is the empty block ready for next OTP refresh/update. If OTP is full, then the last block is the valid block to be used for configure the device.
