Description of problem:
I got some crash report then this. I believe it is the same as already existing abrt bug, just this time for gdb process ...
SELinux is preventing gdb from 'setattr' accesses on the soubor /var/lib/rpm/rpmdb.sqlite-wal.

*****  Plugin restorecon (94.8 confidence) suggests   ************************

Pokud chcete opravit značku.
Výchozí značka pro /var/lib/rpm/rpmdb.sqlite-wal by měla být rpm_var_lib_t.
Then je možné spustit restorecon. Pokus o přístup byl pravděpodobně zastaven kvůli nedostatečným právům pro přístup do nadřazeného adresáře. V takovém případě se pokuste odpovídajícím způsobem změnit následující příkaz.
Do
# /sbin/restorecon -v /var/lib/rpm/rpmdb.sqlite-wal

*****  Plugin catchall_labels (5.21 confidence) suggests   *******************

Pokud chcete povolit gdb přístup typu setattr na rpmdb.sqlite-wal file
Then musíte změnit značku /var/lib/rpm/rpmdb.sqlite-wal
Do
# semanage fcontext -a -t TYP_SOUBORU '/var/lib/rpm/rpmdb.sqlite-wal'
kde TYP_SOUBORU je jeden z následujících: abrt_tmp_t, abrt_upload_watch_tmp_t, abrt_var_cache_t, abrt_var_log_t, abrt_var_run_t, kdump_crash_t, mail_home_rw_t, mnt_t, mock_var_lib_t, rhsmcertd_var_run_t, rpm_log_t, rpm_var_cache_t, rpm_var_run_t, usr_t.
Pak proveďte:
restorecon -v '/var/lib/rpm/rpmdb.sqlite-wal'


*****  Plugin catchall (1.44 confidence) suggests   **************************

Pokud jste přesvědčeni, že má gdb mít ve výchozím stavu přístup setattr na rpmdb.sqlite-wal file.
Then měli byste tento problém nahlásit jako chybu.
Abyste přístup povolili, můžete vygenerovat lokální modul pravidel.
Do
prozatím tento přístup povolíte příkazy:
# ausearch -c 'gdb' --raw | audit2allow -M my-gdb
# semodule -X 300 -i my-gdb.pp

Karle,

Do you know how did you get into this issue? Was is e. g. a system upgrade, or a database backend change?

this is the first time I got it for gdb; before, I was getting it for abrt which I thought it was already reported, but I couldn't find it so I've created a new one - see bug 1885137

and I'm getting it since upgrade from F32 to F33

because it was for abrt-action-sav (bug 1881163) while I got it for abrt-action-lis (bug 1885137)
