Subject: MINOR: quic: stress CRYPTO Rx buffer wrapping
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=1a4f4b4b32172a6bdd900a4c25d6110be8b69570;p=thirdparty%2Fhaproxy.git

MINOR: quic: stress CRYPTO Rx buffer wrapping

Force CRYPTO Rx buffer to be unaligned when running under stress. Most
of the time, this will cause a connection error with
CRYPTO_BUFFER_EXCEEDED as CRYPTO wrapping is not yet implemented.
