Subject: Report EADDRNOTAVAIL and EADDRINUSE as RESOURCELIMIT
X-Git-Tag: tor-0.2.3.16-alpha~12^2
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=2b6e91c2ee4f89c0ee31c83c3a5e5414fd2b3d40;p=thirdparty%2Ftor.git

Report EADDRNOTAVAIL and EADDRINUSE as RESOURCELIMIT

These errors usually mean address exhaustion; reporting them as such
lets clients adjust their load to try other exits.

Fix for bug 4710; bugfix on 0.1.0.1-rc, which started using
END_STREAM_REASON_RESOURCELIMIT.
