crypto: aesni-intel - fix unaligned cbc decrypt for x86-32

2012-06-17T18:23:10+00:00

commit 7c8d51848a88aafdb68f42b6b650c83485ea2f84 upstream.

The 32 bit variant of cbc(aes) decrypt is using instructions requiring
128 bit aligned memory locations but fails to ensure this constraint in
the code. Fix this by loading the data into intermediate registers with
load unaligned instructions.

This fixes reported general protection faults related to aesni.

crypto: aesni-intel - fix aesni build on i386

2011-05-17T23:03:34+00:00

Fix build error on i386 by moving function prototypes:

arch/x86/crypto/aesni-intel_glue.c: In function 'aesni_init':
arch/x86/crypto/aesni-intel_glue.c:1263: error: implicit declaration of function 'crypto_fpu_init'
arch/x86/crypto/aesni-intel_glue.c: In function 'aesni_exit':
arch/x86/crypto/aesni-intel_glue.c:1373: error: implicit declaration of function 'crypto_fpu_exit'

crypto: aesni-intel - Merge with fpu.ko

2011-05-16T05:12:47+00:00

Loading fpu without aesni-intel does nothing.  Loading aesni-intel
without fpu causes modes like xts to fail.  (Unloading
aesni-intel will restore those modes.)

One solution would be to make aesni-intel depend on fpu, but it
seems cleaner to just combine the modules.

This is probably responsible for bugs like:

crypto: aesni-intel - Fix remaining leak in rfc4106_set_hash_key

2011-02-16T02:04:09+00:00

Fix up previous patch that failed to properly fix mem leak in 
rfc4106_set_hash_subkey(). This add-on patch; fixes the leak. moves 
kfree() out of the error path, returns -ENOMEM rather than -EINVAL when 
ablkcipher_request_alloc() fails.

crypto: aesni-intel - Don't leak memory in rfc4106_set_hash_subkey

2011-01-23T07:59:17+00:00

There's a small memory leak in 
arch/x86/crypto/aesni-intel_glue.c::rfc4106_set_hash_subkey(). If the call 
to kmalloc() fails and returns NULL then the memory allocated previously 
by ablkcipher_request_alloc() is not freed when we leave the function.

I could have just added a call to ablkcipher_request_free() before we 
return -ENOMEM, but that started to look too much like the code we 
already had at the end of the function, so I chose instead to rework the 
code a bit so that there are now a few labels at the end that we goto when 
various allocations fail, so we don't have to repeat the same blocks of 
code (this also reduces the object code size slightly).
