daemon: avoid excessive getsockname() syscalls (!854) · Merge requests · Knot projects / Knot Resolver · GitLab

GitLab now enforces expiry dates on tokens that originally had no set expiration date. Those tokens were given an expiration date of one year later. Please review your personal access tokens, project access tokens, and group access tokens to ensure you are aware of upcoming expirations. Administrators of GitLab can find more information on how to identify and mitigate interruption in our documentation.

Self sign-up has been disabled due to increased spam activity. If you want to get access, please send an email to a project owner (preferred) or at gitlab(at)nic(dot)cz. We apologize for the inconvenience.

Vladimír Čunát requested to merge perf-getsockname-2 into master Jul 25, 2019

Calling this on every incoming UDP request could cost us up to 5% time.

Implementation is not so nice because right now "session" = socket, and we share sockets = sessions for UDP.

In future we will clean this by refactoring session layer.
