Janos Follath e007c9fede Removing 'if' branch from the fix.
This new error shouldn't be distinguishable from other padding errors.
Updating 'bad' instead of adding a new 'if' branch.

Manuel Pégourié-Gonnard 4d04cdcd12 Fix RSA mutex fix
Once the mutex is acquired, we must goto cleanup rather that return.
Since cleanup adjusts the return value, adjust that in test cases.

Also, at cleanup we don't want to overwrite 'ret', or we'll loose track of
errors.

see #257

Manuel Pégourié-Gonnard 88fca3ef0e Fix thread safety issue in RSA operations
The race was due to mpi_exp_mod storing a Montgomery coefficient in the
context (RM, RP, RQ).

The fix was verified with -fsanitize-thread using ssl_pthread_server and two
concurrent clients.

A more fine-grained fix should be possible, locking just enough time to check
if those values are OK and set them if not, rather than locking for the whole
mpi_exp_mod() operation, but it will be for later.

Manuel Pégourié-Gonnard abb674467b Rename md_init_ctx() to md_setup() 2015-03-25 21:55:56 +01:00
Manuel Pégourié-Gonnard 4063ceb281 Make hmac_ctx optional
Note from future self: actually md_init_ctx will be re-introduced with the
same signature later, and a new function with the additional argument will be
added.

Manuel Pégourié-Gonnard ca878dbaa5 Make md_info_t an opaque structure
- more freedom for us to change it in the future
- enforces hygiene
- performance impact of making accessors no longer inline should really be
  negligible
