[Bug 2105376] [NEW] bind05 in ubuntu_ltp_syscalls fails consistently for trusty on openstack amd64 with lowlatency flavor

  Thread Previous • Date Previous • • Thread Next 
Public bug reported:

In s2025.02.10 with trusty:linux 3.13.0-205.256,
ubuntu_ltp_syscalls:bind05 started failing consistently across multiple
runs on openstack amd64 for the lowlatency flavor. The generic flavor
passes the test. In previous cycles, the test also passed for
lowlatency. The test fails like this:

Checking for required user/group ids

'root' user id and group found.
'nobody' user id and group found.
'bin' user id and group found.
'daemon' user id and group found.
Users group found.
Sys group found.
Required users/groups exist.
no big block device was specified on commandline.
Tests which require a big block device are disabled.
You can specify it with option -z

The following commits have been added since the last version of the

9b4da71fd0ae regmap: Fix possible double-free in regcache_rbtree_exit()
b99f71817a70 jfs: add a check to prevent array-index-out-of-bounds in dbAdjTree

8a36766d357a net: inet6: do not leave a dangling sk pointer in inet6_create()
f85d9710dd95 net: defer final 'struct net' free in netns dismantle

If this turns out to be a regression, bisecting these should reveal the
culprit.
