Pasta 20240726 and newer crash with ASSERTION FAILED in flow_hash
by Matt Hamilton 14 Aug '24

14 Aug '24

I am using Podman in Fedora 40, which uses pasta by default for rootless container networking. Fedora 40's base version of passt is `passt-0^20240326.g4988e2b-1.fc40`, but recently two newer versions were released, `passt-0^20240726.g57a21d2-1.fc40` and `0^20240806.gee36266-1.fc40`. After upgrading, one pod kept going offline after a few minutes. The containers remained running, but could not make outbound connections. Journalctl revealed that the pasta process for the pod had crashed with: Aug 08 23:07:55 dev pasta[95859]: ASSERTION FAILED in flow_hash (flow.c:566): pif != PIF_NONE && !inany_is_unspecified(&side->eaddr) && side->eport != 0 && side->fport != 0 Aug 08 23:07:55 dev audit[95859]: SECCOMP auid=1000 uid=1000 gid=1000 ses=1 subj=unconfined_u:unconfined_r:container_runtime_t:s0-s0:c0.c1023 pid=95859 comm="pasta.avx2" exe="/usr/bin/pasta.avx2" sig=31 arch=c000003e syscall=186 compat=0 ip=0x7f8f8c23b64f code=0x80000000 Aug 08 23:07:55 dev audit[95859]: ANOM_ABEND auid=1000 uid=1000 gid=1000 ses=1 subj=unconfined_u:unconfined_r:container_runtime_t:s0-s0:c0.c1023 pid=95859 comm="pasta.avx2" exe="/usr/bin/pasta.avx2" sig=31 res=1 After much debugging, I isolated the trigger to a particular container making a peer-to-peer TCP connection to a remote address with port 0. Reverting passt to version 20240326 works as expected, and the container stays online. It's been a long time since I wrote any C, but the code seems clear and checks that the endpoint and forwarding ports do not equal 0. I assume that a port 0 connection is not realistic or useful, and that actual attempt to connect over this port indicate a bug in the client code. Is this correct? I've reported the behavior to the container authors, but am checking here too in case I'm off base.

apparmor blocks passt running podman
by hamish-passt＠moffatt.email 07 Jun '24

Hi, I have podman 5.1.0 and passt 0.0+20240523.765eb0bf running on Debian bookworm (via unofficial packages). When I try to run podman using passt for networking, it is blocked by apparmor (3.0.8). audit: type=1400 audit(1717756950.285:65): apparmor="DENIED" operation="open" profile="passt" name="/run/user/1000/netns/netns-cad489f7-d3c4-7730-9d15-17ae8e172da4" pid=246135 comm="passt.avx2" requested_mask="r" denied_mask="r" fsuid=1000 ouid=0 I'm not familiar with apparmor so I don't know how to debug this. The installed apparmor profile files match the ones in the pasta git. Can you help? thanks, Hamish
