Bug 605338

I've reworked the code significantly for another issue (bgo #619931) in master but that's not going to hit 0.8.1.  I guess we can try to fix that in 0.8.1 separately.

NetworkManager-0.8.1-4.git20100817.fc12 has been submitted as an update for Fedora 12.

I reopen this bug, as it appears that there's still a problem in the sense that /etc/hosts is not restored when the wired interface is unplugged, and when the hostname is restored back to localhost.localdomain.

/etc/hosts remains unchanged :

# Do not remove the following line, or various programs
# that require network functionality will fail.
192.168.128.103	bonobo.example.com	bonobo	# Added by NetworkManager
127.0.0.1	localhost.localdomain	localhost
::1	bonobo.example.com	bonobo	localhost6.localdomain6	localhost6

Note that we've removed all code touching /etc/hosts from NM upstream.  I believe the issue you're experiencing here was already fixed by:

82dd97c4b73ace6067fbe3fa92a3c7eb5a95e89b
ee9ce6027b3fc0cb4aa14442ef8b628b80b726eb
bbf3f12d7b2c79c49d87d41e6cf7b65ac7782071

Which all should be present in NetworkManager-0.8.1-9.git20100831.fc12 and later.  What version do you have installed?

Hi Dan,

yes, I'm running this version with the three patches included. I see two issues in the current code:

 - the short hostname added to the loopback entry with patch bbf3f12d7b2c79c49d87d41e6cf7b65ac7782071 should be removed when hostname comes back to localhost.localdomain, with a mechanism just like old_hostname. Else, it becomes part of the variable custom6, and remains in the loopback entry.

 - with the /etc/hosts from comment #12, when nm_policy_get_etc_hosts() is called with hostname="localhost.localdomain" and old_hostname="bonobo.example.com", all conditions found_localhost4, found_host4, found_localhost6, found_host6, host4_before, host6_before, no_stale are set to true, and /etc/hosts is not modified. I think that when evaluating the ::1 line, the found_localhost6 should be set conditionally if this line doesn't contain the old_hostname to be removed, ditto for found_localhost4

patch follows.

Created attachment 469702 [details]
drop the short old hostname from local mapping

this patch passes the ./test-policy-hosts tests

This message is a reminder that Fedora 13 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 13.  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bug reports from releases that are no longer maintained.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 '13'.

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 13's end of life.

Bug Reporter: Thank you for reporting this issue and we are sorry that 
we may not be able to fix it before Fedora 13 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 please change the 'version' of this 
bug to the applicable version.  If you are unable to change the version, 
please add a comment here and someone will do it for you.

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.

The process we are following is described here: 
http://fedoraproject.org/wiki/BugZappers/HouseKeeping

Fedora 13 changed to end-of-life (EOL) status on 2011-06-25. Fedora 13 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.

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