Description of changes:
Our existing grep checks for posix return types, but not S2N_RESULT return types. So it misses
return S2N_RESULT_ERROR
mistakes.Testing:
The updated script found a couple existing mistakes, which I fixed. The only actual problem was
s2n_async_get_actions
. The other instances didn't set s2n_errno, but relied on a previous call having just failed and kept the error code from that failure. RESULT_GUARD does the same thing.By submitting this pull request, I confirm that my contribution is made under the terms of the Apache 2.0 license.
