Patch which correct the sandbox violation

This patch correct the sandbox violation by disabling the verification of the current virus database of ClamAV, which cause the violation trying to access the database in /var/lib bypassing the sandbox.

Ebuild to merge clamassassin with the patch I submit
Comment 4 Andrej Kacian (RETIRED) gentoo-dev 2007-03-23 21:41:32 UTC
Seems to me that "addpredict" could be better than a patch in this case. Correct path to the lock file needs to be extracted from clamd.conf though (directive DatabaseDirectory).

After stracing clamscan, I can see that it continues to scan even if the lock file can't be created (run by regular user, who doesn't have write access to DatabaseDirectory). I guess using "adddeny" would be even better here, so the merge process doesn't touch the live system.

Tom?
Comment 5 Xavier Parizet 2007-03-23 23:17:30 UTC
I don't understand...
Under the sandboxshell, there is no violation, even if I call src_compile as emerge do.
Any idea ?
Comment 6 Richard Freeman gentoo-dev 2007-04-09 00:27:58 UTC
I get the same problem on amd64.  I'm not sure it should be keyworded stable on amd64 with this issue.
Comment 7 Andrej Kacian (RETIRED) gentoo-dev 2007-04-09 11:42:40 UTC
I've added code which gets correct DatabaseDirectory from clamd.conf, and adds an appropriate addpredict call, so sandbox doesn't bomb out because of this.

Please sync in few hours and give the new 1.2.3 a try.

I still get a sandbox violation, but for /var/lib/clamav/main.inc/.dbLock (open_wr).

Comment 9 Andrej Kacian (RETIRED) gentoo-dev 2007-04-11 12:49:22 UTC
Hm, interesting - I didn't know that more locations are tried. Anyway, I've added an addpredict call for whole DatabaseDirectory, so it should catch every attempt now.
Comment 10 Ylosar Goer 2007-04-11 14:05:07 UTC
resolved fixed i think :)
Comment 11 Andrej Kacian (RETIRED) gentoo-dev 2007-04-11 17:08:30 UTC
Great! :)
Comment 12 Ylosar Goer 2007-04-11 17:55:13 UTC
Should'nt it be RESOLVED FIXED instead of CLOSED TEST-REQUEST ?
(not that i realy care... but it sound weird to me;)

Comment 13 Andrej Kacian (RETIRED) gentoo-dev 2007-04-11 18:38:21 UTC
Yes, it should, but noone really cares, and the only important thing is that both RESOLVED and CLOSED bugs disappear from results of saved searches developers set up - for example, this bug no longer shows up on my "net-mail bugs" search. :)
