| 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.

- updated to 2.69
- An audit was performed on libcap and friends by https://x41-dsec.de/ (blog) . The audit (final report, 2023-05-10) was sponsored by the the Open Source Technology Improvement Fund, https://ostif.org/ (blog). Five issues were found. Four of them are addressed in this release. Each issue was labeled in the audit results as follows:
- LCAP-CR-23-01 (SEVERITY) LOW (CVE-2023-2602) - found by David Gstir (bsc#1211418)
- LCAP-CR-23-02 (SEVERITY) MEDIUM (CVE-2023-2603) - found by Richard Weinberger (bsc#1211419)
- LCAP-CR-23-100 (SEVERITY) NONE
- LCAP-CR-23-101 (SEVERITY) NONE
- LCAP-CR-23-102 (SEVERITY) NONE
- Man page style improvement from Emanuele Torre
* Thu Mar 30 2023 dmueller@suse.com
- update to 2.68:
* Force libcap internal functions to be hidden outside the library
* Expanded the list of man page (links) to all of the supported API
functions.
* fixed some formatting issues with the libpsx(3) manpage.
* Add support for a markdown preamble and postscript when generating
.md versions of the man pages (Bug 217007)
* psx package clean up
* fix some copy-paste errors with TestShared()
* added a more complete psx testing into this test as well
* cap package clean up
* drop an unnecessary use of ", _" in the sources
* cleaned up cap.NamedCount documentation
* Converted goapps/web/README to .md format and fixed the
instructions to indicate go mod tidy is needed.
* cap_compare test binary now cleans up after itself (Bug 217018)
* Figured out how to cross compile Go programs for arm (i.e. RPi) that
use C code, don't use cgo but do use the psx package
* Eliminate use of vendor directory
* Fri Mar 24 2023 mliska@suse.cz
- Enable LTO and add missing -ffat-lto-objects for the provided
static libs.
* Fri Mar 24 2023 tiwai@suse.com
- Revert LTO again; it still breaks builds
* Thu Mar 23 2023 mliska@suse.cz
- Enable LTO as it works fine.
* Sat Feb 04 2023 dmueller@suse.com
- update to 2.67:
* Replace use of fgrep with grep -F (POSIX grep flags preferred by
GNU grep) - patch from David Seifert.
* Added SPDX identifiers to License file(s). Hopefully this will
help the various robots out there correctly identify the
longstanding licenses for libcap and friends. (Bug: 216609
reported by Günther Noack)
* Started down the rabbit hole of trying to address (Bug: 216610
reported by Günther Noack on behalf of Michael Stapelberg)
* The basic issue is how to link C code with Go psx without using
CGo. This is all a low level hackery. If you are interested,
browse the source.
* Correct for bad whatis entries in man pages (this was throwing a
Debian build test, detail)
* Also reviewed man pages and addressed cross linkage issues (Bug:
* Cleaned up some README.md files (made a github mirror now just so
I can automatically render them).
* Changed meaning of DYNAMIC=no builds.
This now builds everything with static linking except for libc.
The reason for this exception is explained in the commit message.
* Inserted demonstration exploit code in capso.so to support
article.
* Thu Sep 29 2022 dmueller@suse.com
- update to 2.66:
* Fix documentation typos in cap_from_text.3
* Some getpcaps code clean up and a fix for PID argument parsing from Jakub
Wilk.
* Slightly more robust Makefiles to address an error with make -j48 test observed
* Include a simple Go program, captrace, to trace kernel capability validation
checks
* This program can be used to figure out what capabilities a program needs to
operate.
* captrace (a wrapper for bpftrace) uses BPF kprobes to monitor the kernel for
capability checks and whether or not they succeed for the system, a specific
PID or a program's direct execution.
* Trim down the default file capabilities for contrib/sucap/su to those actually
needed and set USER and HOME environment variables so bash doesn't complain
about a sourcing error.
* Fri Jul 22 2022 dmueller@suse.com
- update to 2.65:
* Fix syntax error in DEBUG build of protected code in setcap.c.
* Prevent bash from reading the wrong startup files when the capsh --user=xxx
argument is used to invoke a shell as the user xxx. This is done by capsh now
changing the USER and HOME environment variables when --user is specified.
The argument --noenv can be used to suppress this behavior to what used to be
the problematic default. (Bug: 215926)
* Improved documentation
* Tue Apr 12 2022 dmueller@suse.com
- update to 2.64:
* Fix memory leak in libpsx at program exit.

* Bug fix for Go package "cap" and launching
* Build cleanups
* Documentation updates: cap_max_bits has a man page entry
* Recognize default securebits as a libcap mode: HYBRID
* Sun Nov 21 2021 andreas.stieger@gmx.de
- libcap 2.61:

setcap
* Fix executable mode for all of the .so files. There were two
situations where this was failing (with a hard to debug SIGSEGV
inside libc)
* Added an example of a shared library object with its own file
capability
* Fix the top-level include for Make.Rules in the contrib/sucap
example application
* Add support for running constructors at libcap.so start up time
when running as stand alone binary.
- includes changes from 2.60:
* Some build, code linting fixes, the addition of the
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
- update to 2.59:
* 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

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

* Mon Mar 22 2021 dmueller@suse.com
- update to 2.49:

* 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

* 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.
