From 6fbff7fc8aabeee2254405f254220bbe8c05c67d Mon Sep 17 00:00:00 2001

Subject: [PATCH] crypto-api: always allocate memory when serializing iovec_t
The AEAD iov interface falls back to serializing the input buffers if
the low-level cipher doesn't support scatter/gather encryption.
However, there was a bug in the functions used for the serialization,
which causes memory leaks under a certain condition (i.e. the number
of input buffers is 1).
This patch makes the logic of the functions simpler, by removing a
micro-optimization that tries to minimize the number of calls to
malloc/free.
The original problem was reported by Marius Steffen in:
https://bugzilla.samba.org/show_bug.cgi?id=14399
and the cause was investigated by Alexander Haase in:
https://gitlab.com/gnutls/gnutls/-/merge_requests/1277
