Subject: vcl: RX event may lost when accept session repeatedly
X-Git-Tag: v20.05-rc0~177
X-Git-Url: https://gerrit.fd.io/r/gitweb?a=commitdiff_plain;ds=sidebyside;h=96453fd2417ebd1d69354a7fb692976129cea80e;p=vpp.git

vcl: RX event may lost when accept session repeatedly

Type: fix

Some applications may call accept repeatedly to process all connect
request until get EAGIAIN error. Subsequent call may get RX event of
previous accepted session, then should process it rather than just
discard it.
