snd_seq_oss_synth_make_info() incorrectly reports information to userspace without first checking for the validity of the device number, leading to possible information leak (CVE-2008-3272).

2008-01-31[ALSA] Remove sound/driver.hTakashi Iwai19-19/+0
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.

2008-01-31[ALSA] Remove sequencer instrument layerTakashi Iwai9-2045/+3
Remove sequencer instrument layer from the tree. This mechanism hasn't been used much with the actual devices. The only reasonable user was OPL3 loader, and now it was rewritten to use hwdep instead.

2007-05-08header cleaning: don't include smp_lock.h when not usedRandy Dunlap2-2/+0
Remove includes of <linux/smp_lock.h> where it is not used/needed. Suggested by Al Viro. Builds cleanly on x86_64, i386, alpha, ia64, powerpc, sparc, sparc64, and arm (all 59 defconfigs).

2007-02-14[PATCH] remove many unneeded #includes of sched.hTim Schmielau5-5/+0
After Al Viro (finally) succeeded in removing the sched.h #include in module.h recently, it makes sense again to remove other superfluous sched.h includes. There are quite a lot of files which include it but don't actually need anything defined in there. Presumably these includes were once needed for macros that used to live in sched.h, but moved to other header files in the course of cleaning it up. To ease the pain, this time I did not fiddle with any header files and only removed #includes from .c-files, which tend to cause less trouble. Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha, arm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig, allmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all configs in arch/arm/configs on arm. I also checked that no new warnings were introduced by the patch (actually, some warnings are removed that were emitted by unnecessarily included header files).

2007-02-12[PATCH] mark struct file_operations const 9Arjan van de Ven2-2/+2
Many struct file_operations in the kernel can be "const". Marking them const moves these to the .rodata section, which avoids false sharing with potential dirty data.

This patch converts most uses of list_for_each to list_for_each_entry all across alsa.

2006-06-28[ALSA] Fix misuse of __list_add() in seq_ports.cTakashi Iwai1-4/+2
seq_ports.c::snd_seq_delete_all_ports() uses __list_add() to replace the whole list entries. This results in BUG() with recent FC5 kernel due to a sanity check in __list_add().
