Description Leo Bergolth 2009-03-04 20:28:05 UTC

Description of problem:

The Fedora spec-file misses a dependency on libcap-devel.
Because of this, the current samba rpm is built without support for POSIX capabilities which results for example in broken oplock support. This leads to file buffering being completely disabled.

See
http://thread.gmane.org/gmane.network.samba.general/104511/focus=104535
for details.

Simply adding libcap-devel to Build-Requires should be sufficient to fix
this.

Version-Release number of selected component (if applicable):
Seems to apply to all samba packages in current fedora versions.

How reproducible:

Comment 5 Trevor Cordes 2009-03-30 19:33:36 UTC

Leo, did the 3.2.8-0.27.fc10 update fix your problem?  I'm running it and I am seeing similar behaviour to your samba list report still.  Can you confirm?

Comment 6 Leo Bergolth 2009-03-30 21:07:30 UTC

I'm still running a samba version that I built myself on the corresponding box.
However, it should fix the problem since the new package depends on libcap and smbd is linked against it:

$ rpm -q samba-3.2.8-0.27.fc10 --requires | grep libcap
libcap.so.2

$ ldd /usr/sbin/smbd | grep libcap
        libcap.so.2 => /lib/libcap.so.2 (0x001cb000)
