It is required to turn this boolean on to allow abrt execute its gdb handler and be able to troubleshoot further: # setsebool -P abrt_handle_event on and subsequently report another bug for the affected component. Refer to abrt_handle_event_selinux(8) for more information. Closing as dup of bz#1896648. *** This bug has been marked as a duplicate of bug 1896648 *** |
Description of problem: I switched my lockscreen to light-locker. rebooted computer. Used hard keyes to lock screen, CTRL + ALT + L. After typing password, the unlock was successful, but that's also when the error was trigger. This may also be related to the commands I ran to enable light-locker as a lock screen. xfconf-query -c xfce4-session -p /general/LockCommand -s "light-locker-command -l" --create -t string and I also modified the xflock file as follows: # Lock by xscreensaver or gnome-screensaver, if a respective daemon is running for lock_cmd in \ "$LOCK_CMD" \ "light-locker-command -l" \ <~ this is the line I modified. "xscreensaver-command -lock" \ "gnome-screensaver-command --lock" SELinux is preventing gdb from 'open' accesses on the chr_file /dev/fb0. ***** Plugin catchall (100. confidence) suggests ************************** If you believe that gdb should be allowed open access on the fb0 chr_file by default. Then you should report this as a bug. You can generate a local policy module to allow this access. Do allow this access for now by executing: # ausearch -c 'gdb' --raw | audit2allow -M my-gdb # semodule -X 300 -i my-gdb.pp Additional Information: Source Context system_u:system_r:abrt_t:s0-s0:c0.c1023 Target Context system_u:object_r:framebuf_device_t:s0 Target Objects /dev/fb0 [ chr_file ] Source gdb Source Path gdb Port <Unknown> Host (removed) Source RPM Packages Target RPM Packages SELinux Policy RPM selinux-policy-targeted-36.10-1.fc36.noarch Local Policy RPM selinux-policy-targeted-36.10-1.fc36.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name (removed) Platform Linux (removed) 5.18.7-200.fc36.x86_64 #1 SMP PREEMPT_DYNAMIC Sat Jun 25 20:06:14 UTC 2022 x86_64 x86_64 Alert Count 1 First Seen 2022-07-02 18:52:09 PDT Last Seen 2022-07-02 18:52:09 PDT Local ID cccc2ec3-895e-4649-bc33-23caaed0f031 Raw Audit Messages type=AVC msg=audit(1656813129.844:325): avc: denied { open } for pid=2592 comm="gdb" path="/dev/fb0" dev="devtmpfs" ino=420 scontext=system_u:system_r:abrt_t:s0-s0:c0.c1023 tcontext=system_u:object_r:framebuf_device_t:s0 tclass=chr_file permissive=0 Hash: gdb,abrt_t,framebuf_device_t,chr_file,open Version-Release number of selected component: selinux-policy-targeted-36.10-1.fc36.noarch Additional info: component: selinux-policy reporter: libreport-2.17.1 hashmarkername: setroubleshoot kernel: 5.18.7-200.fc36.x86_64 type: libreport
