The new rwlock implementation upstream has seen a series of fixes upstream that need to get corrected before rhel-8.0 GA.
This bug is about the following fix:
Bug 23844 - pthread_rwlock_trywrlock results in hang
- Currently under RCA.
This fix should be included in rhel-8.0.0 branch when available.
"glibc: Fix new rdlock stall."
We are targeting this fix for HTB SNAP4. Setting exception? and going to get exception+.
This bug affects the following threading APIs:
These APIs are used by a lot of applications, but it is only a specific use of them that can trigger a hang.
This flaw is close to being a blocker+, but isn't quite, and so I am seeing exception+ for this bug to commit a fix in SNAP4.
Since the problem described in this bug report should be
resolved in a recent advisory, it has been closed with a
resolution of ERRATA.
