* crypto: nx - Fixing the limit number of bytes to be processedLeonidas S. Barbosa2014-11-062-22/+113
| | | | | | | | | | | | | | | | | | The previous limits were estimated locally in a single step basead on bound values, however it was not correct since when given certain scatterlist the function nx_build_sg_lists was consuming more sg entries than allocated causing a memory corruption and crashes. e.g.: in the worst case we could have one sg entry for a single byte. This patch fixes it modifying the logic of the bound limit moving it to nx_sg_build_lists and set a correct sg_max limit, adding a trim function to ensure the bound in sg_list. Also fixing nx_build_sg_list NULL and untreated return in case of overflow. Signed-off-by: Leonidas S. Barbosa <leosilva@linux.vnet.ibm.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* crypto: nx - Fix SHA concurrence issue and sg limit boundsLeonidas S. Barbosa2014-11-062-230/+200
| | | | | | | | | | | | | | NX SHA algorithms stores the message digest into tfm what cause a concurrence issue where hashes may be replaced by others. This patch cleans up the cases where it's handling unnecessarily shared variables in nx context and copies the current msg digest to a sctx->state in order to safetly handle with the hashe's state. Also fixes and does some clean ups regarding the right sg max limit and bounds to the sg list avoind a memory crash. Signed-off-by: Leonidas S.

* crypto: aesni - remove unnecessary #defineValentin Rothberg2014-11-061-6/+2
| | | | | | | | | | | | | | | | | The CPP identifier 'HAS_PCBC' is defined when the Kconfig option CRYPTO_PCBC is set as 'y' or 'm', and is further used in two ifdef blocks to conditionally compile source code. This indirection hides the actual Kconfig dependency and complicates readability. Moreover, it's inconsistent with the rest of the ifdef blocks in the file, which directly reference Kconfig options. This patch removes 'HAS_PCBC' and replaces its occurrences with the actual dependency on 'CRYPTO_PCBC' being set as 'y' or 'm'.

We want to audit when seccomp is killing a process. seccomp hooks in before the audit syscall entry code. audit_syscall_entry took as an argument the arch of the given syscall. Since the arch is part of what makes a syscall number meaningful it's an important part of the record, but it isn't available when seccomp shoots the syscall... For most arch's we have a better way to get the arch (syscall_get_arch) So the solution was two fold: Implement syscall_get_arch() everywhere there is audit which didn't have it. Use syscall_get_arch() in the seccomp audit code. Having syscall_get_arch() everywhere meant it was a useless flag on the stack and we could get rid of it for the typical syscall entry. The other changes inside the audit system aren't grand, fixed some records that had invalid spaces. Better locking around the task comm field. Removing some dead functions and structs. Make some things static.
