[Group.of.nepali.translators] [Bug 1580731] Re: augeas-lenses filter for PHP files doesn't match php7.0-* files
Following a discussion with Bryce earlier, on behalf of the SRU team I'm declining this SRU and mark it Won't Fix. It might have been relevant to fix in Xenial at the time, but the bug has now been fixed in newer releases including in two newer LTS releases. The benefit to Xenial users seems minimal now, especially as not a single user has stepped up to test Jon's proposed fix in four years. As the impact on users on Xenial therefore appears to be zero, I don't think it's appropriate to SRU this now, when balanced against the regression risk of toolchain changes mutating a rebuild. If the situation changes and users do appear who are affected, then we can reconsider. Note that I've not considered any other factors. If users are affected, an appropriate answer may still be to upgrade rather than SRUing this fix. ** Changed in: augeas (Ubuntu Xenial) Status: Triaged => Won't Fix -- You received this bug notification because you are a member of नेपाली भाषा समायोजकहरुको समूह, which is subscribed to Xenial.

The location of php configuration files moved in php7, to a directory augeas doesn't look in. [Test Case] - Create lxc container $ sudo apt-get install php7.0-cli $ sudo apt-get install augeas-lenses augeas-tools $ augtool ls /files/etc/php ## (no output) - Add the PPA $ augtool ls /files/etc/php 7.0/ = (none) [Regression Potential] Since this makes the PHP configuration accessible to augeas where it wasn't before, behaviors to watch for would relate to php configuration issues when augeas (or puppet) are in use. It is expected that by now most administrators will have worked around the problem by using some other method to configure php, so it is unlikely users would experience behavior regression. [Fix] This adds the "/etc/php/*/*/*.ini" path to the php lense for augeas, following what upstream has done, and that we carry in newer versions of Ubuntu. [Discussion] While it is true that Xenial is old at this point, enterprises that use configuration automation software like augeas sometimes still need older versions of Ubuntu (e.g. via ESM). PHP has been a popular choice for many enterprises in the past, so it is expected that PHP 5 -> 7.0 upgrades are still relevant. So, given that, plus the simplicity of this fix it seems still worthy of SRU. [Original Report] The filter list in /usr/share/augeas/lenses/dist/php.aug includes: /etc/php*/*/*.ini /etc/php*/fpm/pool.d/*.conf This will match the php5-fpm package files: /etc/php5/fpm/php.ini /etc/php5/fpm/pool.d/*.conf But not the php7.0-fpm package files: /etc/php/7.0/fpm/php.ini /etc/php/7.0/fpm/pool.d/*.conf Puppet handles this badly because augeas won't report that anything has changed trying to set options in /etc/php/7.0/fpm/php.ini, so it does nothing instead of reporting an error: Debug: Augeas[php_sessions](provider=augeas): Will attempt to save and only run if files changed Debug: Augeas[php_sessions](provider=augeas): sending command 'set' with params ["/files/etc/php/7.0/fpm/php.ini/Session/session.gc_maxlifetime", "604800"] Debug: Augeas[php_sessions](provider=augeas): Skipping because no files were changed Debug: Augeas[php_sessions](provider=augeas): Closed the augeas connection augeas-lenses: Installed: 1.4.0-0ubuntu1 Candidate: 1.4.0-0ubuntu1 Version table: *** 1.4.0-0ubuntu1 500 500 http://gb.archive.ubuntu.com/ubuntu xenial/main amd64 Packages 500 http://gb.archive.ubuntu.com/ubuntu xenial/main i386 Packages 100 /var/lib/dpkg/status php7.0-fpm: Installed: 7.0.4-7ubuntu2ppa1 Candidate: 7.0.4-7ubuntu2ppa1 Version table: *** 7.0.4-7ubuntu2ppa1 1000 1000 http://ppa.launchpad.net/sa.me.uk/um/ubuntu xenial/main amd64 Packages 100 /var/lib/dpkg/status 7.0.4-7ubuntu2 500 500 http://gb.archive.ubuntu.com/ubuntu xenial/universe amd64 Packages To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/augeas/+bug/1580731/+subscriptions ___ Mailing list: https://launchpad.net/~group.of.nepali.translators Post to : group.of.nepali.translators@lists.launchpad.net Unsubscribe : https://launchpad.net/~group.of.nepali.translators More help : https://help.launchpad.net/ListHelp

It changes alg_sock's ref counter to atomic, which addresses the root cause. [Test Case] * There is a synthetic test case available, which uses a kprobes kernel module to synchronize the concurrent CPUs on the instructions responsible for the problem; and a userspace part to run it. * The organic reproducer is the Varnish Cache Plus software with the Crypto vmod (which uses kernel crypto userspace API) under long, very high load. * The patch has been verified on both reproducers with the 4.15 and 5.7 kernels. - * More tests performed with 'stress-ng --af-alg' -with 11 CPUs on Xenial/Bionic/Disco/Eoan/Focal -(all on same version of stress-ng, V0.11.14) + * More tests performed with 'stress-ng --af-alg' + with 11 CPUs on Xenial/Bionic/Disco/Eoan/Focal + (all on same version of stress-ng, V0.11.14) -No regressions observed from original kernel. -(the af-alg stressor can exercise almost all -kernel crypto modules shipped with the kernel; -so it checks more paths/crypto alg interfaces.) + No regressions observed from original kernel. + (the af-alg stressor can exercise almost all + kernel crypto modules shipped with the kernel; + so it checks more paths/crypto alg interfaces.) [Regression Potential] * The fix patch does a fundamental change in how alg_sock reference counters work, plus another change to the 'nokey' counting. This of course *has* a risk of regression. * Regressions theoretically could manifest as use after free errors (in case of undercounting) in the af_alg functions or silent memory leaks (in case of overcounting), but also other behaviors since reference counting is key to many things. * FWIW, this patch has been written by the crypto subsystem maintainer, who certainly knows a lot of the normal and corner cases, thus giving the patch more credit. * Testing with the organic reproducer ran as long as 5 days, without issues, so it does look good.
