Thanks for sharing this.

Sorry, can you rephrase?
I sure hope there are not thousands of issues with ASAN.


Are all identified issues reported in dpdk.org bugzilla?
It would help to have a hint in the bzs title, like "caught with ASAN".

I can't find a report about the infinite loop on invalid fds, making a
dpdk app unable to exit gracefully with ASAN enabled.
But at least, I sent a fix for this, waiting for Anatoly to review.

Anatoly and Jerin like your patch, but it is still a RFC and there
were comments on a missing release note update and unit test.
Please address those comments and submit a regular patch.


Thanks.
