  - 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

- 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

- Enable LTO and add missing -ffat-lto-objects for the provided
  static libs.

- Revert LTO again; it still breaks builds

- Enable LTO as it works fine.

- 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.

- 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.
