Description of problem: I was getting the following errors. Jun 06 10:06:13 ganak. kdumpctl[981]: No memory reserved for crash kernel. Jun 06 10:06:13 ganak. kdumpctl[981]: Starting kdump: [FAILED] To solve it I executed system-config-kdump Which opened a gui where initially "Firmware assisted dump" was selected by default. It automatically selected "Manual Settings" & filled "New kdump Memory" to 128(MB) while "Current kdump Memory" remained 0 (MB) At this point the 3 selinux alerts happened. type=AVC msg=audit(1496811012.375:1681): avc: denied { read } for pid=10088 comm="grubby" name="sr0" dev="devtmpfs" ino=11675 scontext=system_u:system_r:kdumpgui_t:s0-s0:c0.c1023 tcontext=system_u:object_r:removable_device_t:s0 tclass=blk_file permissive=0 type=AVC msg=audit(1496811013.149:1682): avc: denied { write } for pid=10088 comm="grubby" name="/" dev="tmpfs" ino=11695 scontext=system_u:system_r:kdumpgui_t:s0-s0:c0.c1023 tcontext=system_u:object_r:var_run_t:s0 tclass=dir permissive=0 type=AVC msg=audit(1496811013.149:1683): avc: denied { write } for pid=10088 comm="grubby" name="log" dev="sda3" ino=617 scontext=system_u:system_r:kdumpgui_t:s0-s0:c0.c1023 tcontext=system_u:object_r:var_log_t:s0 tclass=dir permissive=0 SELinux is preventing grubby from 'read' accesses on the blk_file sr0. ***** Plugin catchall (100. confidence) suggests ************************** If you believe that grubby should be allowed read access on the sr0 blk_file by default. Then you should report this as a bug. You can generate a local policy module to allow this access.
