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/ ====================

forward=redirect file descriptor leak
by Karl Seguin 28 Jan '21

28 Jan '21

It appears that when configured with forward=redirect, there's a leak for every connection. I've reproduced using the two latest releases: ./monetdbd create ./farm ./monetdbd set forward=redirect ./farm ./monetdbd set listenaddr=127.0.0.1 ./farm ./monetdbd start ./farm ./monetdb create test ./monetdb release test lsof -p $(pidof monetdbd) | wc -l 40 ./mclient -d test -s "select 1" lsof -p $(pidof monetdbd) | wc -l 41 ./mclient -d test -s "select 1" lsof -p $(pidof monetdbd) | wc -l 42 ./mclient -d test -s "select 1" lsof -p $(pidof monetdbd) | wc -l 43 Karl

by Sjoerd Mullender 25 Jan '21

25 Jan '21

The MonetDB team at MonetDB BV is pleased to announce the Oct2020-SP2 bugfix release of the MonetDB suite of programs. More information about MonetDB can be found on our website at <https://www.monetdb.org/>. For details on this release, please see the release notes at <https://www.monetdb.org/Downloads/ReleaseNotes>. As usual, the download location is <https://www.monetdb.org/downloads/>. Oct2020-SP2 Bugfix Release (11.39.11) SQL Frontend * CREATE [OR REPLACE] TRIGGER schema_name.trigger_name is now disallowed, because the trigger will be stored on the same schema as the table it refers to.

Bug Fixes * 6862: mserver5: crashes under update_table() when calling lib_sql.so ( max_clients = 2048) * 7002: monetdb stop fails * 7012: mclient enters an infinite loop when a file on the command line does not exist * 7013: Select * on grouped view: wrong error "cannot use non GROUP BY column 'a1' in query results without an aggregate function" * 7017: mal seems to leak in functions * 7020: release an older savepoint causes "BATproject2: does not match always" * 7021: savepoints crash mserver5 * 7022: transaction with an unreleased savepoint not properly persisted * 7023: CREATE VIEW: SELECT: cannot use non GROUP BY column '%1' in query results without an aggregate function * 7024: DELETE FROM or TRUNCATE on freshly created table leads to loosing all further inserts in same transaction * 7030: DROP TABLE with AUTO_INCREMENT doesn't drop sequence causing left-over dependency * 7034: User with sysadmin role cannot create another user * 7035: UPDATE and SELECT column privileges * 3772: Any user can grant a role.
