...obsolete client (retrocomputing, don't ask) crash with "seccomp violation" for the writev() call -- and after I added it to the allow list, for the tgkill() call. However, the writev() call in question is this: [pid 592791] writev(2, [{iov_base="free(): double free detected in tcache 2", iov_len=40}, {iov_base="\n", iov_len=1}], 2) = 41 So the tgkill() probably makes sense as it comes from libc itself, rather than from OpenSSH. The client in question is PuTTY_Release_0.64, which seems to trigger "compat KEX proposal" in sshd. Version 0.65 doesn't...

...ses I get an unexpeced output - hence the report. Bug Summary ------- When competing nft ruleset imports are running, and the ruleset is dumped (with `nft list ruleset`), a couple of rare errors can be seen: 1. An error message returned by `nft list ruleset`: "free(): double free detected in tcache 2" 2. Output is composed of duplicate (or even trippled) dumps of the same tables/rules Test files to reproduce ----------------------- R1.tf ``` #!/usr/sbin/nft -f flush ruleset table inet filter { set DROP-NETS-V4 { type ipv4_addr flags interval elements = {...

I know, and i have him the "samba" solution, because ... I dont know sssd also. And i dont get the fuss on samba+winbind or samba+sssd I have 3 services running minimal : samba winbind user-homes.automount Everything works as it should. I hope, and i'll add the note here also. NOTE ! My packages are NOT sssd compliant, you need to recompile SSSD yourselfs agains my samba
