Subject: child-create: Raise an ALERT_TS_MISMATCH when receiving TS_UNACCEPTABLE
X-Git-Tag: 6.0.3rc1~7^2~1
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=86a50d161820603e5aa024be7f76944c6c8525ce;p=thirdparty%2Fstrongswan.git

child-create: Raise an ALERT_TS_MISMATCH when receiving TS_UNACCEPTABLE

When sending a TS_UNACCEPTABLE notify, a ALERT_TS_MISMATCH is sent, but
not when receiving one. This seems inconsistent compared to proposal
mismatch handling, so extend the child_create task to raise such an alert.
