-Subject: [PATCH] tools/virtiofsd: Add rseq syscall to the seccomp allowlist
-
-The virtiofsd currently crashes when used with glibc 2.35.
-That is due to the rseq system call being added to every thread
-creation [1][2].

-
-This happens not at daemon start, but when a guest connects
-
-    /usr/lib/qemu/virtiofsd -f --socket-path=/tmp/testvfsd -o sandbox=chroot \
-        -o source=/var/guests/j-virtiofs --socket-group=kvm
-    virtio_session_mount: Waiting for vhost-user socket connection...
-    # start ok, now guest will connect
-    virtio_session_mount: Received vhost-user socket connection
-    virtio_loop: Entry
-    fv_queue_set_started: qidx=0 started=1
-    fv_queue_set_started: qidx=1 started=1
-    Bad system call (core dumped)
-
-We have to put rseq on the seccomp allowlist to avoid that the daemon
-is crashing in this case.
