[PATCH v2] tap: Drop frames if no client connected
by Yumei Huang 25 Sep '25

25 Sep '25

If no client is attached, discard outgoing frames and report them as sent. Without this we will get an EBADF in either writev() (pasta) or sendmsg() (passt). That's basically harmless, but a bit ugly. Explicitly catching this case results in behaviour that's probably a bit clearer to debug if we hit it. There are several different approaches we can take here. Here's some reasoning as David explained: * Don't listen() until the tap connection is ready - It's not clear that the host rejecting the connection is better than the host accepting, then the connection stalling until the guest is ready. - Would require substantial rework because we currently listen() as we parse the command line and don't store the information we'd need to do it later. * Don't accept() until the tap connection is ready - To the peer, will behave basically the same as this patch - the host will complete the TCP handshake, then the connection will stall until the guest is ready. - More work to implement, because essentially every sock-side handler has to check fd_tap and abort early * Drop packets in tap_send_frames(), but return 0 - To the peer, would behave basically the same - Would make the TCP code do a bunch of busy work attempting to resend, probably to no avail - Handling of errors returned by tap_send_frames() is on the basis that it's probably a transient fault (buffer full) and we want to resend very soon. That approach doesn't make sense for a missing guest.

I'd rather call it observation. We're just piling up workarounds because merge requests are not really evaluated or accepted, for example https://github.com/fedora-selinux/selinux-policy/pull/1613. Your own comment to it: https://github.com/fedora-selinux/selinux-policy/pull/1613#issuecomment-146… perfectly explains one of the biggest maintainability concerns I have, because not being able to use interfaces as designed leads to issues such as: https://github.com/fedora-selinux/selinux-policy/issues/2579 for which, again, I could propose a simple change, but I don't exactly have confidence that it will be considered. That leads in turn to more workarounds, say: https://passt.top/passt/commit/?id=87471731e6bb0b5df3a50277527caf3381b45ee4 https://passt.top/passt/commit/?id=98d474c8950e9cc5715d5686614fb0f504377303 I don't understand how the fact that it's been like that since 2007 would suggest a positive or negative correlation to maintainability. Things keeps breaking and I keep adding more workarounds, not fixes. You can go ahead and blame me for that, but I was talking about how *I* perceive maintainability. Again: > 1. libvirt's SELinux policy doesn't seem to be really maintainable / > long-term sustainable to me ^^ ...we probably have different concepts of it.

About disk images, of course, that's what I added for libguestfs: /** mrwlk and that's the same in libvirt's AppArmor policy. The set of permitted capabilities is very different, though, and libguestfs doesn't of course need all those helpers or, say, the ability to mount /dev, which, with AppArmor, can't be qualified / limited much further than that. > Only the > spawned QEMU could be confined strictly, and that would be equiv to > what is already done with libvirt's policy for QEMU. ...see links above?

[PATCH v8 0/8] Use true MAC address of LAN local remote hosts
by Jon Maloy 22 Sep '25

22 Sep '25

Bug #120 asks us to use the true MAC addresses of LAN local remote hosts, since some programs need this information. These commits introduces this for ARP, NDP, UDP, TCP and ICMP. --- v3: Updated according to feedback from Stefano and David: - Made the ARP/NDP lookup call filter out the requested address by itself, qualified by the index if the template interface - Moved the flow specific MAC address from struct flowside to struct flow_common. v4: - Updated according to feedback from David and Stefan - Added a cache table for ARP/NDP table contents v5: - Updated according to feedback from David and Stefan - Added cache table entries to FIFO/LRU queue - New criteria for when to consult ARP/NDP v6: - Simplified and merged mac cache table commits - Other changes after feedback from David. v7: - Fixes in patch #2 based on feedback from David and Stefano. v8: - Redesigned netlink and cache table part to be based on a subscription model.
