Can you point to it? The only problem I know about is a missing SELinux policy extension for samba-dcerpcd daemon which prevent ipasam module from loading. samba-dcerpcd got a new SELinux context which is not allowed to do anything that ipasam is supposed to do: read /etc/krb5.conf, initialize openssl configuration, communicate with LDAP server, etc. This is handled in https://bugzilla.redhat.com/show_bug.cgi?id=2096521 for RHEL 9.1 (C9S) and in https://bugzilla.redhat.com/show_bug.cgi?id=2096825 for RHEL 8.7 (C8S). A workaround is to put SELinux into permissive mode until SELinux folks would produce a fix -- or apply a local policy extension described in the bugzillas. > >-> $ systemctl restart smb.service > >Starting Samba SMB Daemon... >[2022/06/08 19:17:32.937351, 0, pid=49122] >../../source3/smbd/server.c:1741(main) > smbd version 4.16.1 started. > Copyright Andrew Tridgell and the Samba Team 1992-2022 >[2022/06/08 19:17:32.960756, 0, pid=49122] >../../lib/util/fault.c:172(smb_panic_log) >=============================================================== >[2022/06/08 19:17:32.960925, 0, pid=49122] >../../lib/util/fault.c:176(smb_panic_log) > INTERNAL ERROR: Signal 6: Aborted in pid 49122 (4.16.1) >[2022/06/08 19:17:32.960981, 0, pid=49122] >../../lib/util/fault.c:181(smb_panic_log) > If you are running a recent Samba version, and if you think this >problem is not yet fixed in the latest versions, please consider >reporting this bug, see https://wiki.samba.org/index.php/Bug_Reporting >[2022/06/08 19:17:32.961022, 0, pid=49122] >../../lib/util/fault.c:182(smb_panic_log) >=============================================================== >[2022/06/08 19:17:32.961056, 0, pid=49122] >../../lib/util/fault.c:184(smb_panic_log) > PANIC (pid 49122): Signal 6: Aborted in 4.16.1 >[2022/06/08 19:17:32.961647, 0, pid=49122] >../../lib/util/fault.c:288(log_stack_trace) > BACKTRACE: 15 stack frames: > #0 /lib64/libsamba-util.so.0(log_stack_trace+0x34) [0x7f41bbc0c7c4] > #1 /lib64/libsamba-util.so.0(smb_panic+0xd) [0x7f41bbc0ca1d] > #2 /lib64/libsamba-util.so.0(+0xeab9) [0x7f41bbc0cab9] > #3 /lib64/libpthread.so.0(+0x12ce0) [0x7f41bb83bce0] > #4 /lib64/libc.so.6(gsignal+0x10f) [0x7f41bb2a4a4f] > #5 /lib64/libc.so.6(abort+0x127) [0x7f41bb277db5] > #6 /lib64/libtalloc.so.2(+0x2f40) [0x7f41a34a7f40] > #7 /lib64/libtalloc.so.2(+0x336c) [0x7f41a34a836c] > #8 /usr/lib64/samba/pdb/ipasam.so(+0x11c2f) [0x7f41a38e7c2f] > #9 /lib64/libsamba-passdb.so.0(make_pdb_method_name+0xb2) >[0x7f41bbdae2f2] > #10 /lib64/libsamba-passdb.so.0(+0x1d604) [0x7f41bbdae604] > #11 /lib64/libsamba-passdb.so.0(initialize_password_db+0x1d) >[0x7f41bbdb096d] > #12 /usr/sbin/smbd(main+0x5d9) [0x55c945bbcf09] > #13 /lib64/libc.so.6(__libc_start_main+0xf3) [0x7f41bb290ca3] > #14 /usr/sbin/smbd(_start+0x2e) [0x55c945bbe6de] >[2022/06/08 19:17:32.962008, 0, pid=49122] >../../source3/lib/dumpcore.c:318(dump_core) > coredump is handled by helper binary specified at >/proc/sys/kernel/core_pattern > >smb.service: Main process exited, code=dumped, status=6/ABRT >smb.service: Failed with result 'core-dump'. >Failed to start Samba SMB Daemon. > >many thanks, L. >_______________________________________________ >CentOS-devel mailing list >CentOS-devel at centos.org >https://lists.centos.org/mailman/listinfo/centos-devel -- / Alexander Bokovoy Sr. Principal Software Engineer Security / Identity Management Engineering Red Hat Limited, Finland
