Title:
Chrony test hangs with libpcap2 1:2.31-1
Status in chrony package in Ubuntu:
Confirmed
Status in libcap2 package in Ubuntu:
New
Status in libcap2 package in Debian:
Fix Released
Bug description:
Tests are blocking and failing eventually with a timeout.
Hits all architectures and is reproducible.
Locally reproducible in autopkgtest:
sudo ~/work/autopkgtest/autopkgtest/runner/autopkgtest --no-built-
binaries --apt-upgrade --apt-pocket=proposed=src:libpcap2 --shell-fail
chrony_3.5-5ubuntu1.dsc -- qemu --qemu-options='-cpu host' --ram-
size=2048 --cpus 2 ~/work/autopkgtest-focal-amd64.img
Seems to be a block on network on __skb_wait_for_more_packets
$cat /proc/3833/wchan
__skb_wait_for_more_packets
From strace POV that is a wait in accept that does not unblock:
$ sudo strace -rT -p 3833
strace: Process 3833 attached
0.000000 accept(6, NULL, NULL
