[jira] [Resolved] (DAEMON-242) jsvc cannot find libcap.so on
debian-based distributions
[ https://issues.apache.org/jira/browse/DAEMON-242?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Mladen Turk resolved DAEMON-242.
--------------------------------
Resolution: Fixed
Fix Version/s: 1.0.10
Fixed in the svn. Will be part of 1.0.10
The fix tries to load libcap.so.2, libcap.so.1, libcap.so in that order. If libcap still cannot be found the legacy syscall is used and error message logged.

> Key: DAEMON-242
> URL: https://issues.apache.org/jira/browse/DAEMON-242
> Project: Commons Daemon
> Issue Type: Bug
> Components: Jsvc
> Affects Versions: 1.0.9
> Environment: Debian 6.0.2
> Ubuntu 11.04
> Reporter: Phil Clay
> Fix For: 1.0.10

> Debian-based distributions do not symlink the "main" shared object to the major version.
> For example:
> On RHEL4u4:
> $ ls -l /lib/libcap.so*
> lrwxrwxrwx 1 root root 11 Jun 13 2007 /lib/libcap.so -> libcap.so.1
> lrwxrwxrwx 1 root root 14 Jun 12 2007 /lib/libcap.so.1 -> libcap.so.1.10
> -rwxr-xr-x 1 root root 11784 Oct 7 2006 /lib/libcap.so.1.10
> Notice libcap.so -> libcap.so.1
> On Debian 6.02:
> $ ls -l /lib/libcap.so*
> lrwxrwxrwx 1 root root 14 Jan 25 10:19 /lib/libcap.so.2 -> libcap.so.2.19
> -rw-r--r-- 1 root root 16640 Aug 16 2010 /lib/libcap.so.2.19
> On Ubuntu 11.04:
> $ ls -l /lib/libcap.so*
> lrwxrwxrwx 1 root root 14 2011-07-16 09:52 /lib/libcap.so.2 -> libcap.so.2.20
> -rw-r--r-- 1 root root 13816 2011-02-15 14:35 /lib/libcap.so.2.20
> Notice there is no libcap.so -> libcap.so.2
> Therefore, when jsvc attempts to load libcap.so, it fails...
> I see this when running jsvc -debug ...
> Attemtping to load library /lib/libcap.so
> Attemtping to load library /usr/lib/libcap.so
> failed loading capabilities library -- /usr/lib/libcap.so: cannot open shared object file: No such file or directory.
> set_caps(CAPS) failed for user 'oncommand'
> Service exit with a return value of 4
> If I create the libcap.so -> libcap.so.2 symlink, it works.
> I'm guessing the fix for this would be to load libcap.so, libcap.so.2, libcap.so.1 in progression to see if any work.
> (Note that I have performed the workaround I mentioned in https://issues.apache.org/jira/browse/DAEMON-241 to get this far.)
