Description steinach2810 2013-04-27 11:17:02 UTC
Description of problem:
SELinux is preventing /usr/sbin/sendmail.sendmail from using the 'net_admin' capabilities.

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

If you believe that sendmail.sendmail should have the net_admin capability 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:
# grep newaliases /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

Comment 1 Miroslav Grepl 2013-04-29 07:09:49 UTC
Does everything work correctly?

Comment 2 Miroslav Grepl 2013-04-29 07:10:19 UTC
CAP_NET_ADMIN
              Perform various network-related operations:
              * interface configuration;
              * administration of IP firewall, masquerading, and accounting
              * modify routing tables;
              * bind to any address for transparent proxying;
              * set type-of-service (TOS)
              * clear driver statistics;
              * set promiscuous mode;
              * enabling multicasting;
              * use setsockopt(2) to set the following socket options: SO_DEBUG,
                SO_MARK,  SO_PRIORITY (for a priority outside the range 0 to 6),
                SO_RCVBUFFORCE, and SO_SNDBUFFORCE

Comment 3 Jaroslav Škarvada 2013-04-29 12:04:45 UTC
No idea why the newaliases needed the CAP_NET_ADMIN. For the reporter: could you provide your /etc/aliases? Could you provide the steps that triggered this?

Comment 4 Fedora End Of Life 2013-12-21 13:16:15 UTC
This message is a reminder that Fedora 18 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 18. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as WONTFIX if it remains open with a Fedora 
'version' of '18'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version prior to Fedora 18's end of life.

Thank you for reporting this issue and we are sorry that we may not be 
able to fix it before Fedora 18 is end of life. If you would still like 
to see this bug fixed and are able to reproduce it against a later version 
of Fedora, you are encouraged  change the 'version' to a later Fedora 
version prior to Fedora 18's end of life.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events. Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.

Comment 5 Fedora End Of Life 2014-02-05 21:07:00 UTC
Fedora 18 changed to end-of-life (EOL) status on 2014-01-14. Fedora 18 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version. If you
are unable to reopen this bug, please file a new report against the
current release. If you experience problems, please add a comment to this
bug.

Thank you for reporting this bug and we are sorry it could not be fixed.

Comment 6 Red Hat Bugzilla 2023-09-14 01:43:49 UTC
The needinfo request[s] on this closed bug have been removed as they have been unresolved for 1000 days
