Subject: server_name: Return the actual required buffer size if the buffer is too small
X-Git-Tag: gnutls_3_1_4~74
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=d4b6bd3f3e61ff8af04f4d088718a8873512ca01;p=thirdparty%2Fgnutls.git

server_name: Return the actual required buffer size if the buffer is too small

Since we require space for the null termination, include this in
the info returned if the caller provided a too small buffer.
Otherwise, if the caller allocated a buffer of exactly the suggested
size, it would still be too small.
