Summary0018132: SELinux is preventing /usr/lib/udev/udev-configure-printer from 'read' accesses on the sock_file /var/run/cups/cups.sock.
DescriptionDescription of problem:
1 installed new brother MFC-L2690DW printer
2 linstalled XSANE software
3 did a scan frpm printer to file useing scan button on the printer.
SELinux is preventing /usr/lib/udev/udev-configure-printer from 'read' accesses on the sock_file /var/run/cups/cups.sock.

***** Plugin catchall (100. confidence) suggests **************************

If you believe that udev-configure-printer should be allowed read access on the cups.sock sock_file by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
allow this access for now by executing:
# ausearch -c 'udev-configure-' --raw | audit2allow -M my-udevconfigure
# semodule -i my-udevconfigure.pp

Please try to touch /.autorelabel and reboot in order to relabel the filesystem
If you still have issues after that , please contact Brother and report the bug.

Me too (CentOS 7, up to date, and a Brother printer but not a proprietary driver). I got this when trying to print a pdf using lp and with lpr. I was and am remote so I cannot test well.

type=AVC msg=audit(1617659478.372:1330): avc: denied { read } for pid=5826 comm="udev-configure-" name="cups.sock" dev="tmpfs" ino=21976 scontext=system_u:system_r:cupsd_config_t:s0-s0:c0.c1023 tcontext=system_u:object_r:cupsd_var_run_t:s0 tclass=sock_file permissive=0

Mysteriously, CUPS status included:
        "loadFilename failed: /var/spool/cups/d00014-001: not a PDF file"

When I did a "file" command on the spool file, it was a PDF file. So CUPS is a bit confused by this.

I was able to print when I used using enscript instead of lp. That may have been a coincidence.

I will to a relabel but I cannot retest soon.
