ALSA: seq: Continue broadcasting events to ports if one of them fails

2014-06-04T15:30:58+00:00

Sometimes PORT_EXIT messages are lost when a process is exiting.
This happens if you subscribe to the announce port with client A,
then subscribe to the announce port with client B, then kill client A.
Client B will not see the PORT_EXIT message because client A's port is
closing and is earlier in the announce port subscription list. The
for each loop will try to send the announcement to client A and fail,
then will stop trying to broadcast to other ports. Killing B works fine
since the announcement will already have gone to A. The CLIENT_EXIT
message does not get lost.

How to reproduce problem:

*** termA
$ aseqdump -p 0:1
  0:1   Port subscribed            0:1 -> 128:0

*** termB
$ aseqdump -p 0:1

*** termA
  0:1   Client start               client 129
  0:1   Port start                 129:0
  0:1   Port subscribed            0:1 -> 129:0

*** termB
  0:1   Port subscribed            0:1 -> 129:0

*** termA
^C

*** termB
  0:1   Client exit                client 128
   <--- expected Port exit as well (before client exit)

sound: Add export.h for THIS_MODULE/EXPORT_SYMBOL where needed

2011-10-31T23:31:22+00:00

These aren't modules, but they do make use of these macros, so
they will need export.h to get that definition.  Previously,
they got it via the implicit module.h inclusion.

ALSA: core: sparse cleanups

2011-02-14T16:10:11+00:00

Change the core code where sparse complains.  In most cases, this means
just adding annotations to confirm that we indeed want to do the dirty
things we're doing.

ALSA: core - Define llseek fops

2010-04-13T10:01:21+00:00

Set no_llseek to llseek file ops of each sound component (but for hwdep).
This avoids the implicit BKL invocation via generic_file_llseek() used
as default when fops.llseek is NULL.

Also call nonseekable_open() at each open ops to ensure the file flags
have no seek bit.

ALSA: trivial: sound seq ioctl dbg: print hexadecimal value padded with 0s

2010-02-01T23:27:47+00:00

Instead of padding with blanks and printing "number=0x a", print
"number=0x0a".

ALSA: remove CONFIG_KMOD from sound

2008-07-10T07:32:58+00:00

A bunch of things in alsa depend on CONFIG_KMOD,
use CONFIG_MODULES instead where the dependency
is needed at all.

Dont touch fs_struct in drivers

2008-02-15T05:13:32+00:00

The sound drivers and the pnpbios core test for current->root != NULL.  This
test seems to be unnecessary since we always have rootfs mounted before
initializing the drivers.

[ALSA] Remove sound/driver.h

2008-01-31T16:29:48+00:00

This header file exists only for some hacks to adapt alsa-driver
tree.  It's useless for building in the kernel.  Let's move a few
lines in it to sound/core.h and remove it.
With this patch, sound/driver.h isn't removed but has just a single
compile warning to include it.  This should be really killed in
future.
