| Summary: Library for Capabilities (linux-privs) Support | |
Capabilities are a measure to limit the omnipotence of the superuser. Currently a program started by root or setuid root has the power to do anything. Capabilities (Linux-Privs) provide a more fine-grained access control. Without kernel patches, you can use this library to drop capabilities within setuid binaries. If you use patches, this can be done automatically by the kernel.

- libcap 2.61:

situations where this was failing (with a hard to debug SIGSEGV
inside libc)

cap_fill_flag() API and a memory latency optimization
* General improvement in thread safety for libcap and cap package
* Minor API change replacing libcap:cap_launch_*() void returning
functions with int + errno status returns.
* Added a cap_iab_dup(), and (*cap.IAB).Dup() to API
* New features for capsh: --quiet, -+ and =+ arguments
- add upstream signing key and verify source signature
* Tue Sep 28 2021 info@paolostivanin.com

* Fixed a potential libcap memory leak by adding a destructor
* Major improvement is that there is a path for Linux-PAM compliant
applications to support setting Ambient vector Capabilities via pam_cap.so now
* Added libcap cap_proc_root() API function
* Added color support to captree
* Fixed contrib/sucap/su to correctly handle the Inheritable flag
* capsh enhancements
* getcap -r / now generates readable output
* The shared library objects: pam_cap.so, libcap.so and libpsx.so, are all now
runnable as standalone binaries
* The module pam_cap.so now contains support for a default=<IAB> module argument
* Enhanced capsh --suggest to also compare against the capability value names
and not just their descriptions
* Added capsh --current support
* Added a contrib/sucap/su.c pure-capabilities PAM implementation of su
* Fix for a corner case infinite loop handling long strings
* Added libcap cap_iab_compare() and cap_iab_get_pid() APIs
* Added a Go utility, captree, to display the process (and thread) graph along with
the POSIX.1e and IAB capabilities of each PID{TID} tree.
* Sat Jul 17 2021 dmueller@suse.com
- update to 2.51:
* Fix capsh installation
* Add an autoauth module flag to pam_cap.so
* Unified libcap/cap (Go) and libcap (C) default generation of external format binary data
* API enhancement cap_fill() and (*cap.Set).Fill() - to permit copying one
capability flag to another.
* --explain=cap_foo: describe what cap_foo does
* --suggest=phrase: search all the cap descriptions and describe those that match the phrase
* Add "keepcaps" module argument support to pam_cap.so (reported by Zoltan Fridrich. Bug 212945)
* extend libcap to include cap_prctl() and cap_prctlw() functions to regain
feature parity with Go "cap" package. These are only needed when linking
against -lpsx for keepcaps POSIX semantics.
* this likely requires substantial application changes to make Ambient
capability support usable in general, but doing our part for the admin.
* Add a test case for recent kernel fix
* Go pragma fix for convenience functions in "cap" module
* Wed Jun 02 2021 christophe@krop.fr
- Fix a broken symlink. libcap-devel installs libpsx.so but
didn't install the library it's pointing to.
* Fri Apr 16 2021 tiwai@suse.de
- Add explicit dependency on libcap2 with version to libcap-progs
(bsc#1184690)
* Mon Mar 22 2021 dmueller@suse.com
- update to 2.49:
* Implement cap_func_launcher() and cap.FuncLauncher().
* More robust "psx" redirection for nocgo compilation - the documentation for
the cgo implementation is now included in the nocgo one because the go.dev
automated documentation builds the docs from the nocgo version.
* Lots of documentation cleanups and added a few man pages: for IAB and
Launching.
* Some general no-op License changes that might cause folk to notice but only
for formatting reasons. These were initially inspired by some lawyerly
interactions, but I ended up rolling back half of them because they
confused automated software infrastructure.
* Tue Feb 09 2021 dmueller@suse.com
- update to 2.48:
* More uniform use of $(MAKE) in Makefiles

* Thu Jan 09 2020 mpluskal@suse.com
- Update to version 2.30 (jsc#SLE-17092, jsc#ECO-3460):
* BUGFIX: arm and i386 fixes C and Go setgroups choice - used
wrong syscall in 2.29.
* cleaned up make clean and make install to actually work as
intended
* updated Gentoo libpsx.pc file from Lars Wendler
* refactored the way libpsx linkage with libcap performed mutual
discovery.
* Previously (2.28) libpsx had an API call overridden by libcap
using weak linkage function in libpsx. In 2.30 this is reversed,
namely libpsx provides the stronger function and libcap has a
weak "no-op" version.
* a bit more consistency in handling the 'all' sets in libcap
(C) and libcap/cap (Go). Namely, they both dynamically discover
the number of capabilities named by the kernel and use this as
the definition of 'all' for the current runtime.
+ libcap (C) exports cap_max_bit() to export the number of
supported capabilities
+ libcap/cap (Go) exports cap.MaxBits() for this same value.
