Intel AES-NI is a new set of Single Instruction Multiple Data (SIMD) instructions that are going to be introduced in the next generation of Intel processor, as of 2009. These instructions enable fast and secure data encryption and decryption, using the Advanced Encryption Standard (AES), defined by FIPS Publication number 197. The architecture introduces six instructions that offer full hardware support for AES. Four of them support high performance data encryption and decryption, and the other two instructions support the AES key expansion procedure. The white paper can be downloaded from: http://softwarecommunity.intel.com/isn/downloads/intelavx/AES-Instructions-Set_WP.pdf AES may be used in soft_irq context, but MMX/SSE context can not be touched safely in soft_irq context. So in_interrupt() is checked, if in IRQ or soft_irq context, the general x86_64 implementation are used instead.

cryptd_alloc_ablkcipher() will allocate a cryptd-ed ablkcipher for specified algorithm name. The new allocated one is guaranteed to be cryptd-ed ablkcipher, so the blkcipher underlying can be gotten via cryptd_ablkcipher_child().

We're currently checking the frontend type in init_tfm. This is completely pointless because the fact that we're called at all means that the frontend is ours so the type must match as well. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

Intel AES-NI AES acceleration instructions touch XMM state, to use that in soft_irq context, general x86 AES implementation is used as fallback. The first parameter is changed from struct crypto_tfm * to struct crypto_aes_ctx * to make it easier to deal with 16 bytes alignment requirement of AES-NI implementation.

It turns out that LRW has never worked properly on big endian. This was never discussed because nobody actually used it that way. In fact, it was only discovered when Geert Uytterhoeven loaded it through tcrypt which failed the test on it. The fix is straightforward, on big endian the to find the nth bit we should be grouping them by words instead of bytes. So setbit128_bbe should xor with 128 - BITS_PER_LONG instead of 128 - BITS_PER_BYTE == 0x78.

uids in namespaces other than init don't get a sysfs entry. For those in the init namespace, while we're waiting to remove the sysfs entry for the uid the uid is still hashed, and alloc_uid() may re-grab that uid without getting a new reference to the user_ns, which we've already put in free_user before scheduling remove_user_sysfs_dir().

ASoC supports both explicit codec drivers for AC97 devices and a simple driver which uses the standard ALSA AC97 framework for codec support. When used with the generic AC97 codec support that will provide the ad hoc AC97 device for drivers like touchscreens to attach to so the core shouldn't do so.

Added the helper function snd_hda_multi_out_dig_cleanup() to clean up the digital outputs with multi setup. This call is needed in cases the codec supports multiple digital outputs as slaves. Otherwise the slave widgets aren't properly cleaned up. For a single digital output (e.g. in patch_conexant.c), this call isn't needed. Signed-off-by: Takashi Iwai <tiwai@suse.de>

Change HP dv7 quirk: although reported to work with hp-m4 model (https://bugzilla.novell.com/show_bug.cgi?id=445321), the original report doesn't contain info about testing of internal microphone. Recently I received a report about internal mic not working (https://qa.mandriva.com/show_bug.cgi?id=44855#c193), this must be related with the forced line in on pin 0x0e done with hp-m4 model. Thus change the current quirk from STAC_HP_M4 to STAC_HP_DV5, later reported to be fixed on a provided kernel with this change (https://qa.mandriva.com/show_bug.cgi?id=44855#c196).

When a non-wimax interface is looked up by the stack, a bad pointer is returned when the looked-up interface is not found in the list (of registered WiMAX interfaces). This causes an oops in the caller when trying to use the pointer. Fix by properly setting the pointer to NULL if we don't exit from the list_for_each() with a found entry.

In function sock_getsockopt() located in net/core/sock.c, optval v.val is not correctly initialized and directly returned in userland in case we have SO_BSDCOMPAT option set. This dummy code should trigger the bug: int main(void) { unsigned char buf[4] = { 0, 0, 0, 0 }; int len; int sock; sock = socket(33, 2, 2); getsockopt(sock, 1, SO_BSDCOMPAT, &buf, &len); printf("%x%x%x%x\n", buf[0], buf[1], buf[2], buf[3]); close(sock); } Here is a patch that fix this bug by initalizing v.val just after its declaration.

The problem is that in_atomic() will return false inside spinlocks if CONFIG_PREEMPT=n. This will lead to deadlockable GFP_KERNEL allocations from spinlocked regions. Secondly, if CONFIG_PREEMPT=y, this bug solves itself because networking will instead use GFP_ATOMIC from this callsite. Hence we won't get the might_sleep() debugging warnings which would have informed us of the buggy callsites. Solve both these problems by switching to in_interrupt(). Now, if someone runs a gfp_any() allocation from inside spinlock we will get the warning if CONFIG_PREEMPT=y. I reviewed all callsites and most of them were too complex for my little brain and none of them documented their interface requirements. I have no idea what this patch will do.

The large receive buffer queue is not properly tracking the current index in the case where an early exit occurs. This can happen when a page alloc or dma mapping fails.
