Subject: BUG/MEDIUM: h2: In h2_send(), stop the loop if we failed to alloc a buf.
X-Git-Tag: v2.0-dev1~118
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=2b09443e043bb58b8d3855b21a6b1183f3e1690a;p=thirdparty%2Fhaproxy.git

BUG/MEDIUM: h2: In h2_send(), stop the loop if we failed to alloc a buf.

In h2_send(), make sure we break the loop if we failed to alloc a buffer,
or we'd end up looping endlessly.

This should be backported to 1.9.
