SELinux problems
by Arjen P. de Vries 29 Dec '21

29 Dec '21

Hi all, Not really a bug report because I did not manage to figure out the cause. However, after upgrading from FC31 to FC32 I could not login any more, due to SELinux problems. Auto-relabeling did not work, nothing really... ... until I did dnf uninstall MonetDB-selinux. I came to this point because trying to give systemd services the correct labels with restorecon failed with an error referencing a monetdb specific file. I do not have the details unfortunately, but if you get problems, beware that MonetDB SELinux package and systemd may interfere in some way beyond my knowledge of these services. Best regards, Arjen PS: Some output from logs: sudo ausearch -c monetdb -m AVC,SELINUX_ERR [..] ---- time->Sat May 2 20:57:01 2020 type=AVC msg=audit(1588445821.693:203): avc: denied { open } for pid=1232 comm="monetdbd" path="/etc/resolv.conf" dev="dm-0" ino=3409775 scontext=system_u:system_r:init_t:s0 tcontext=system_u:object_r:default_t:s0 tclass=file permissive=1 ---- time->Sat May 2 21:12:56 2020 type=AVC msg=audit(1588446776.043:1194): avc: denied { execute } for pid=2861 comm="(monetdbd)" name="monetdbd" dev="dm-0" ino=2147256 scontext=system_u:system_r:init_t:s0 tcontext=system_u:object_r:unlabeled_t:s0 tclass=file permissive=1 trawcon="unconfined_u:object_r:monetdbd_exec_t:s0" ---- time->Sat May 2 21:12:56 2020 type=AVC msg=audit(1588446776.043:1195): avc: denied { execute_no_trans } for pid=2861 comm="(monetdbd)" path="/usr/bin/monetdbd" dev="dm-0" ino=2147256 scontext=system_u:system_r:init_t:s0 tcontext=system_u:object_r:unlabeled_t:s0 tclass=file permissive=1 trawcon="unconfined_u:object_r:monetdbd_exec_t:s0" ---- time->Sat May 2 21:12:56 2020 type=AVC msg=audit(1588446776.044:1196): avc: denied { map } for pid=2861 comm="monetdbd" path="/usr/bin/monetdbd" dev="dm-0" ino=2147256 scontext=system_u:system_r:init_t:s0 tcontext=system_u:object_r:unlabeled_t:s0 tclass=file permissive=1 trawcon="unconfined_u:object_r:monetdbd_exec_t:s0" ---- time->Sat May 2 21:12:56 2020 type=AVC msg=audit(1588446776.714:1197): avc: denied { remove_name } for pid=1232 comm="monetdbd" name="merovingian.pid" dev="tmpfs" ino=34369 scontext=system_u:system_r:init_t:s0 tcontext=system_u:object_r:unlabeled_t:s0 tclass=dir permissive=1 trawcon="system_u:object_r:monetdbd_var_run_t:s0" ---- time->Sat May 2 21:12:56 2020 type=AVC msg=audit(1588446776.714:1198): avc: denied { unlink } for pid=1232 comm="monetdbd" name="merovingian.pid" dev="tmpfs" ino=34369 scontext=system_u:system_r:init_t:s0 tcontext=system_u:object_r:unlabeled_t:s0 tclass=file permissive=1 ---- time->Sat May 2 21:12:56 2020 type=AVC msg=audit(1588446776.714:1199): avc: denied { write } for pid=1232 comm="monetdbd" name=".merovingian_lock" dev="dm-0" ino=5899443 scontext=system_u:system_r:init_t:s0 tcontext=system_u:object_r:unlabeled_t:s0 tclass=file permissive=1 trawcon="system_u:object_r:monetdbd_lock_t:s0" ---- time->Sat May 2 21:13:15 2020 type=AVC msg=audit(1588446795.214:1209): avc: denied { read } for pid=2925 comm="(monetdbd)" name="passwd" dev="dm-0" ino=524514 scontext=system_u:system_r:init_t:s0 tcontext=system_u:object_r:var_t:s0 tclass=file permissive=1 ---- time->Sat May 2 21:13:15 2020 type=AVC msg=audit(1588446795.214:1210): avc: denied { open } for pid=2925 comm="(monetdbd)" path="/var/lib/sss/mc/passwd" dev="dm-0" ino=524514 scontext=system_u:system_r:init_t:s0 tcontext=system_u:object_r:var_t:s0 tclass=file permissive=1 ---- time->Sat May 2 21:13:15 2020 type=AVC msg=audit(1588446795.214:1211): avc: denied { map } for pid=2925 comm="(monetdbd)" path="/var/lib/sss/mc/passwd" dev="dm-0" ino=524514 scontext=system_u:system_r:init_t:s0 tcontext=system_u:object_r:var_t:s0 tclass=file permissive=1 ---- time->Sat May 2 21:14:24 2020 type=AVC msg=audit(1588446864.487:1281): avc: denied { read } for pid=3072 comm="(monetdbd)" name="passwd" dev="dm-0" ino=524514 scontext=system_u:system_r:init_t:s0 tcontext=system_u:object_r:var_t:s0 tclass=file permissive=1 ---- time->Sat May 2 21:14:24 2020 type=AVC msg=audit(1588446864.487:1282): avc: denied { open } for pid=3072 comm="(monetdbd)" path="/var/lib/sss/mc/passwd" dev="dm-0" ino=524514 scontext=system_u:system_r:init_t:s0 tcontext=system_u:object_r:var_t:s0 tclass=file permissive=1 ---- time->Sat May 2 21:14:24 2020 type=AVC msg=audit(1588446864.487:1283): avc: denied { map } for pid=3072 comm="(monetdbd)" path="/var/lib/sss/mc/passwd" dev="dm-0" ino=524514 scontext=system_u:system_r:init_t:s0 tcontext=system_u:object_r:var_t:s0 tclass=file permissive=1 -- ==================================================================== ICIS, office M1.00.05 Radboud University Mercator 1 Faculty of Science Toernooiveld 212 arjen(a)cs.ru.nl NL-6525 EC Nijmegen, The Netherlands +31-(0)24-365 2354 ===================== http://www.informagus.nl/ ==================== -- ==================================================================== ICIS, office M1.00.05 Radboud University Mercator 1 Faculty of Science Toernooiveld 212 arjen(a)cs.ru.nl NL-6525 EC Nijmegen, The Netherlands +31-(0)24-365 2354 ===================== http://www.informagus.nl/ ====================

Unable to connect to Monetdb after Upgrade : Challenge string is not valid, it is empty
by AUBERT Simon 02 Jul '21

02 Jul '21

Hello all I had an old monetdb installation on my Windows laptop -Did the upgrade in Oct2020-SP5 Bugfix Release (11.39.17) It really looks like I can start the server C:\Program Files\MonetDB\MonetDB5\bin>mserver5 # MonetDB 5 server v11.39.17 (Oct2020-SP5) # Serving database 'demo', using 4 threads # Compiled for amd64-pc-windows-msvc/64bit # Found 15.862 GiB available main-memory of which we use 12.928 GiB # Copyright (c) 1993 - July 2008 CWI. # Copyright (c) August 2008 - 2021 MonetDB B.V., all rights reserved # Visit https://www.monetdb.org/ for further information # Listening for connection requests on mapi:monetdb://localhost:50000/ # MonetDB/GIS module loaded # MonetDB/SQL module loaded # MonetDB server is started. To stop server press Ctrl-C. But when I want to use the mclient, it asks the user and password and then... nothing and after a few minutes I have this message Challenge string is not valid, it is empty Same thing with an ODBC connection : after a long time, it fails. I have reinstalled Monetdb but nothing changed. I have no idea of what's wrong.
