Revision c42b8a6e4bced8f6ecf0a0d9a0107e6e989da0c2 authored by Matt Caswell on 24 August 2016, 10:28:58 UTC, committed by Matt Caswell on 24 August 2016, 10:28:58 UTC
Remove some dead code from rec_layer_s3.c
It is never valid to call ssl3_read_bytes with
type == SSL3_RT_CHANGE_CIPHER_SPEC, and in fact we check for valid values
for type near the beginning of the function. Therefore this check will never
be true and can be removed.
