Hao,

Ted Ts'o (http://sourceforge.net/users/tytso) is the admin for the CVS
repository that hosts this source code. It has been quite some time
since I've been in a position to work on libcap or capability stuff in
general. I recommend you get Ted to add you as a developer to the
linux-privs project and you can update the sources directly; its about
time for libcap-1.11!

Best wishes

Andrew

FWIW I did make a previous attempt to support file-system capabilities a
number of years ago. Based on the README in this directory, it was circa
2001:

http://www.kernel.org/pub/linux/libs/security/linux-privs/kernel-2.4-fcap/

but the patches there were with respect to a 'very ancient' kernel... In
case anyone finds it useful, the README in that directory contains a
list of features this set of patches supported.
