Re: Very odd: /proc/sys/net/ipv6/conf/all/disable_ipv6
setroubleshoot: SELinux is preventing /usr/sbin/sendmail.sendmail
from
read access on the file disable_ipv6
ll -Z shows
-rw-r--r--. root root system_u:object_r:sysctl_net_t:s0
/proc/sys/net/ipv6/conf/all/disable_ipv6
I find this peculiar. Anyone have a resolution, or is this a bug?
Though the combination sounds alarming, this is probably only a file
descriptor left open by whatever program called sendmail. That program
should either close the file disable_ipv6 after use or set the
CLOSE_ON_EXEC flag in the file descriptor.
If you search for it, there are many such cases, even bug reports for
CentOS-7:
https://bugs.centos.org/view.php?id=12396
But no solution yet.
Which program calls sendmail in your case?
Best regards
