* Simplify clonefdMiloslav Trmač2010-07-191-2/+0
| | | | | | | get_unused_fd() already sets the right bit in open_fds, no need to do it again (compare e.g. sys_dup()). Signed-off-by: Nikos Mavrogiannopoulos <nmav@gnutls.org>

* Fix cryptodev_hash_deinitMiloslav Trmač2010-07-191-1/+5
| | | | | This function may be called even if hdata was never initialized, so only free the crypto API data structures if they are not NULL.

* Fix cipher_data deinitialization.Miloslav Trmač2010-07-191-4/+8
| | | | | | | | | Guard crypto API *free* with "if (ptr)"; it works without the guards, but that seems to be an implementation detail - at least in the case of crypto_ablkcipher. Free them in the opposite order of allocation, async.request points to async.result and async.s.
* Fix a race in ncr_data_set.Miloslav Trmač2010-07-191-3/+6
| | | | | | | | | | | More than one thread could could pass the if (... > max_data_size) test, leading to multiple executions of "data->data_size += get.data_size", resulting in data->data_size > data->max_data_size. This is a minimal fix that ensures kernel data structure consistency, but the behavior won't look atomic from user space (two threads appending N and M bytes could result in N, M, or N+M more bytes). It relies on the assumption that reads and writes of size_t are atomic.
