It could be a situation, that tasklet is executed twice because of certain delay between dma callback and irq handler execution. In that case, second tasklet execution could actually corrupt the data of the new started dma transactions. This patch improves tasklet logic and prevents above described cases. Signed-off-by:

Calling omap_sham_handle_queue from "done" tasklet should be done after irq scheduled tasklet completes. Having additional tasklet does not solve that issue because it might be execute before. So queue handling tasklet has been removed and functionality integrated into single tasklet. Signed-off-by:

Couple of context flags have been moved to device flags. IRQ and tasklet handlers does not need to access request context anymore. Signed-off-by:

Some flags are changed in interrupt handlers and verified in the tasklet. There might be a race condition when tasklet is interrupted or another cpu/core will run IRQ handler and tasklet in parallel. Atomic bitops functions are now used instead of bitmask operations. Signed-off-by:

Flags mask cannot be used with atomic bit operations. This patch changes masks to bit numbers. Atomic bit operations will be used by following patches. Signed-off-by:

Jump to the end of the function for the clk_disable and clk_put rather than returning directly. A simplified version of the semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @r exists@ expression e1,e2; statement S; @@ e1 = clk_get@p1(...); ... when != e1 = e2 when != clk_put(e1) when any if (...) { ... when != clk_put(e1) when != if (...) { ... clk_put(e1) ... } * return@p3 ...; } else S // </smpl> Signed-off-by:

FIPS compliance requires a known-answer self-test for all approved cipher and mode combinations, for all valid key sizes. Presently, there are only self-tests for xts-aes-128. This adds a 256-bit one, pulled from the same reference document, which should satisfy the requirement. Signed-off-by:

instead of calling it manually in case if cifs_read_super() fails to set ->s_root, just call it from ->kill_sb(). cifs_put_super() is gone now *and* we have cifs_sb shutdown and destruction done after the superblock is gone from ->s_instances. Acked-by:

cifs_sb and nls end up leaked... Acked-by:
-
Al Viro authored
To close sget() races we'll need to be able to set cifs_sb up before we get the superblock, so we'll want to be able to do cifs_mount() earlier. Fortunately, it's easy to do - setting ->s_maxbytes can be done in cifs_read_super(), ditto for ->s_time_gran and as for putting MS_POSIXACL into ->s_flags, we can mirror it in ->mnt_cifs_flags until cifs_read_super() is called. Kill unused 'devname' argument, while we are at it... Acked-by:

if cifs_sb allocation fails, we still need to drop nls we'd stashed into volume_info - the one we would've copied to cifs_sb if we could allocate the latter. Acked-by:
-
Al Viro authored
if we get to out_super with ->s_root already set (e.g. with cifs_get_root() failure), we'll end up with cifs_put_super() called and ->mountdata freed twice. We'll also get cifs_sb freed twice and cifs_sb->local_nls dropped twice. The problem is, we can get to out_super both with and without ->s_root, which makes ->put_super() a bad place for such work. Switch to ->kill_sb(), have all that work done there after kill_anon_super(). Unlike ->put_super(), ->kill_sb() is called by deactivate_locked_super() whether we have ->s_root or not. Acked-by:
