Fix proposal
Hello,
encrypt_multi and decrypt_multi seems to process too many data when the
underlying buffer is larger than the data to process.
Steps to reproduce: use encrypt_multi/decrypt_multi into an IPSEC context (for
ciphering ESP). Decryption will erase the authentication data contained at the
end of the mbuf.
I attached a patch with the fixup I used.
