libnih (upstart dependency) ported to kFreeBSD/eglibc


Back in September at the Linux Plumbers Conference in New Orleans, James Hunt and I presented Upstart roadmap, which included porting Upstart to kFreeBSD/glibc. The first milestone is now complete.

Libnih is ported to kFreeBSD/eglibc. During the course to get there the following has happened:

  • Later libnih test-suite gets a test case failure, which is then reported to FreeBSD.org. Turns out some syscalls on FreeBSD returned bogus siginfo_t.si_status information in some cases. Luckily there is now a full test-case and kernel patch posted by Jilles Tjoelker. Once that's committed upstream, I'll push for uploads to the affected kernels in Debian.


  • A few small patches applied to libnih, mostly adding POSIX compliant header includes and the like. 
So with a patched libc and patched kernel one can compile libnih & run its test-suite. There are however some caveats feature miss-partiy:

  •  nih_watch / inotify support is disabled. This is TODO on my list to port nih_watch to use kevent/kqueue EVFILT_VNODE.
  • FreeBSD kernel doesn't have abstract namespace domain sockets, so at the moment I have disabled some abstract namespace test-cases & changed dbus-connection tests to use pathname sockets instead. This is still a TODO because unlink before bind is not done, and the socket is not cleaned up after servers close it at the moment.




With all caveats above, here are the test-suite results:

Achieving actually full disk encryption of UEFI ESP at rest with TCG OPAL, FIPS, LUKS

Achieving full disk encryption using FIPS, TCG OPAL and LUKS to encrypt UEFI ESP on bare-metal and in VMs Many security standards such as CIS and STIG require to protect information at rest. For example, NIST SP 800-53r5 SC-28 advocate to use cryptographic protection, offline storage and TPMs to enhance protection of information confidentiality and/or integrity. Traditionally to satisfy such controls on portable devices such as laptops one would utilize software based Full Disk Encryption - Mac OS X FileVault , Windows Bitlocker , Linux cryptsetup LUKS2 . In cases when FIPS cryptography is required, additional burden would be placed onto these systems to operate their kernels in FIPS mode. Trusted Computing Group  works on establishing many industry standards and specifications, which are widely adopted to improve safety and security of computing whilst keeping it easy to use. One of their most famous specifications them is TCG  TPM 2.0 (Trusted Platform Module). TPMs are now...

Encrypt all the things

xkcd #538: Security Went into blogger settings and enabled TLS on my custom domain blogger blog. So it is now finally a https://blog.surgut.co.uk  However, I do use feedburner and syndicate that to the planet. I am not sure if that is end-to-end TLS connections, thus I will look into removing feedburner between my blog and the ubuntu/debian planets. My experience with changing feeds in the planets is that I end up spamming everyone. I wonder, if I should make a new tag and add that one, and add both feeds to the planet config to avoid spamming old posts. Next up went into gandi LiveDNS platform and enabled DNSSEC on my domain. It propagated quite quickly, but I believe my domain is now correctly signed with DNSSEC stuff. Next up I guess, is to fix DNSSEC with captive portals. I guess what we really want to have on "wifi" like devices, is to first connect to wifi and not set it as default route. Perform captive portal check, potentially with a reduced DNS server capabil...

Security-only OpenSSL tarball releases for CVE-2026-2673

On Friday May the 13th OpenSSL project has published advisory details for  CVE-2026-2673 . The CVE is treated as non-important by the project. The patches are only provided as commits on the stable branches. No git tag, no precise fixed version, and no source tarballs provided. The patches that were merged to openssl-3.5 and openssl-3.6 branches were not based on top of the last stable point release and did not split code changes & documentation updates. It means that cherry-picking the commits referenced in the advisory will always lead to conflicts requiring manual resolution. It is not clear if support is provided for snapshot builds off the openssl-3.5 and openssl-3.6 branches. As the builds from the stable branches declare themselves as dev builds of the next unreleased point release. For example, in contrast to projects such as vim and glibc, with every commit to stable branches explicitly recommended for distributors to ship and is supported. I have requested OpenSSL ups...
