12 years agoALSA: PCM - Add PCM creation API for internal PCMs.
Liam Girdwood [Wed, 8 Feb 2012 20:33:31 +0000 (20:33 +0000)] 
ALSA: PCM - Add PCM creation API for internal PCMs.

The new ASoC dynamic PCM core needs to create PCMs and substreams that are
for use by internal ASoC drivers only and not visible to userspace for
direct IO. These new PCMs are similar to regular PCMs expect they have no
device nodes or procfs entries. The ASoC component drivers use them in exactly
the same way as regular PCMs for PCM and DAI operations.

The intention is that a dynamic PCM based driver will register both regular
PCMs and internal PCMs. The regular PCMs will be used for all IO with userspace
however the internal PCMs will be used by the driver to route digital audio
through numerous back end DAI links (with potentially a DSP providing different
hw_params, DAI formats based on the regular front end PCM params) to devices
like CODECs, MODEMs, Bluetooth, FM, DMICs, etc

This patch adds a new snd_pcm_new_internal() API call to create the internal PCM
without device nodes or procfs. It also adds adds a new internal flag to snd_pcm.

pcmcia: fix socket refcount decrementing on each resume

This fixes a memory-corrupting bug: not only does it cause the warning,
but as a result of dropping the refcount to zero, it causes the
pcmcia_socket0 device structure to be freed while it still has
references, causing slab caches corruption.  A fatal oops quickly
follows this warning - often even just a 'dmesg' following the warning
causes the kernel to oops.

While testing suspend/resume on an ARM device with PCMCIA support, and a
CF card inserted, I found that after five suspend and resumes, the
kernel would complain, and shortly die after with slab corruption.

As can be seen, the original function called pcmcia_get_socket() and
pcmcia_put_socket() around the guts, whereas the replacement code
calls pcmcia_put_socket() only in one path.  This creates an imbalance
in the refcounting.

Testing with pcmcia_put_socket() put removed shows that the bug is gone:

avoids entering a new zone by never going beyond the free scanned.

The fix is straight-forward.  isolate_migratepages() has to make a
similar check to isolate_freepage to ensure that it never isolates pages
from a zone it does not hold the LRU lock for.

12 years agotarget: Change target_submit_cmd() to return void

target: Change target_submit_cmd() to return void

Retval not very useful, and may even be harmful. Once submitted, fabrics
should expect a sense error if anything goes wrong. All fabrics checking
of this retval are useless or broken:

fc checks it just to emit more debug output.
ib_srpt trickles retval up, then it is ignored.
qla2xxx trickles it up, which then causes a bug because the abort goto
in qla_target.c thinks cmd hasn't been sent to target.

Just returning nothing is best.

12 years agotarget: accept REQUEST_SENSE with 18bytes
Sebastian Andrzej Siewior [Wed, 18 Jan 2012 13:04:29 +0000 (14:04 +0100)] 
target: accept REQUEST_SENSE with 18bytes

WindowsXP+BOT issues a MODE_SENSE request with page 0x1c which is not
suppoerted by target. Target rejects that command with
TCM_INVALID_CDB_FIELD, so far so good. On BOT I can't send the SENSE
response back, instead I can only reply that an error occured. The next
thing happens is a REQUEST_SENSE request with 18 bytes length. Since the
check here is more than 18 bytes I have to NACK that request as well.
This is not really required: We check for some additional room, but we
never use it. The additional length is set to 0xa so the total length is
0xa + 8 = 18 which is fine with my 18 bytes.

12 years agomd: two small fixes to handling interrupt resync.

md: two small fixes to handling interrupt resync.

1/ If a resync is aborted we should record how far we got
 (recovery_cp) the last request that we know has completed
 (->curr_resync_completed) rather than the last request that was
 submitted (->curr_resync).

2/ When a resync aborts we still want to update the metadata with
 any changes, so set MD_CHANGE_DEVS even if we 'skip'.

exec: fix use-after-free bug in setup_new_exec()

Setting the task name is done within setup_new_exec() by accessing
bprm->filename. However this happens after flush_old_exec().
This may result in a use after free bug, flush_old_exec() may
"complete" vfork_done, which will wake up the parent which in turn
may free the passed in filename.
To fix this add a new tcomm field in struct linux_binprm which
contains the now early generated task name until it is used.
