[Bug 2057576] Re: php-fpm sometimes SIGSEGVs (signal 11) when running fpm_get_status
Reproducing the issue in mantic with the script provided in the SRU test
plan:
+ echo 'Number of SIGSEGV failures:'
Number of SIGSEGV failures:
+ lxc exec php-fpm-segfault -- sh -c 'cat /var/log/php8.2-fpm.log | grep -c
SIGSEGV'
5102
Which confirms the issue.
When tryong to verify the fix, I got the following result:
+ echo 'Number of SIGSEGV failures:'
Number of SIGSEGV failures:
+ lxc exec php-fpm-segfault -- sh -c 'cat /var/log/php8.2-fpm.log | grep -c
SIGSEGV'
315
Further runs with and without the fix are quite consistent: I get
thousands of failures for the package in the release pocket, and a few
hundreds with the package in proposed.
Before marking this as a verification failure, I would like to dig a bit
more to ensure this is not a different bug or a a issue with local
resources.
This is the modified test plan script used to install the packages from
the proposed pocket:
#!/bin/bash
set -eux
trap cleanup EXIT
UBUNTU_SERIES=${UBUNTU_SERIES:-mantic}
PHP_VERSION=${PHP_VERSION:-8.2}
TEST_CONTAINER=php-fpm-segfault
PHP_TEST_FILE=$(mktemp)
PROPOSED_REPO_FILE=$(mktemp)
PROPOSED_PREF=$(mktemp)
cleanup() {
rm -f ${PHP_TEST_FILE}
rm -f ${PROPOSED_REPO_FILE}
rm -f ${PROPOSED_PREF}
lxc delete -f ${TEST_CONTAINER}
}
cat > ${PHP_TEST_FILE} <
${PROPOSED_REPO_FILE} ${PROPOSED_PREF}

+ Running the script above ensuring the php packages from proposed are

[ Where problems could occur ]
The change in question is straightforward:
We are replacing a string interpolation for a string literal because the
variables being substituted could result in a null pointer dereference.
Unless some other software components are parsing the logs, which are
being changed (which would result in chained failures across
components), issues could occur due to unrelated issues with possible
new dependencies after a full PHP rebuild.
[ Other Info ]
This is fixed upstream in php-8.3.1, php-8.2.14, and php-8.1.27. Hence,
this should be fixed in noble, but needs fixing in mantic, jammy, and
focal.

[Bug 2057576] Re: php-fpm sometimes SIGSEGVs (signal 11) when running fpm_get_status
Thanks Lars, I will proceed with the SRUs then! This is fixed upstream in php-8.3.1, php-8.2.14, and php-8.1.27. Hence, this should be fixed in noble, but needs fixing in mantic, jammy, and focal. ** Also affects: php7.4 (Ubuntu Jammy) Importance: Undecided Status: New ** Also affects: php8.1 (Ubuntu Jammy) Importance: Undecided Status: New ** Also affects: php8.2 (Ubuntu Jammy) Importance: Undecided Status: New ** Also affects: php7.4 (Ubuntu Mantic) Importance: Undecided Status: New ** Also affects: php8.1 (Ubuntu Mantic) Importance: Undecided Status: New ** Also affects: php8.2 (Ubuntu Mantic) Importance: Undecided Status: New ** Also affects: php7.4 (Ubuntu Focal) Importance: Undecided Status: New ** Also affects: php8.1 (Ubuntu Focal) Importance: Undecided Status: New ** Also affects: php8.2 (Ubuntu Focal) Importance: Undecided Status: New ** No longer affects: php7.4 (Ubuntu Jammy) ** No longer affects: php7.4 (Ubuntu Mantic) ** No longer affects: php8.1 (Ubuntu Focal) ** No longer affects: php8.1 (Ubuntu Mantic) ** No longer affects: php8.2 (Ubuntu Focal) ** No longer affects: php8.2 (Ubuntu Jammy) ** Changed in: php8.2 (Ubuntu Mantic) Status: New => Triaged ** Changed in: php8.1 (Ubuntu Jammy) Status: New => Triaged ** Changed in: php8.2 (Ubuntu) Status: Triaged => Invalid ** Changed in: php8.1 (Ubuntu) Status: Triaged => Invalid ** Changed in: php7.4 (Ubuntu) Status: Triaged => Invalid ** Changed in: php7.4 (Ubuntu Focal) Status: New => Triaged ** Changed in: php7.4 (Ubuntu) Assignee: Athos Ribeiro (athos-ribeiro) => (unassigned) ** Changed in: php7.4 (Ubuntu Focal) Assignee: (unassigned) => Athos Ribeiro (athos-ribeiro) ** Changed in: php8.1 (Ubuntu Jammy) Assignee: (unassigned) => Athos Ribeiro (athos-ribeiro) ** Changed in: php8.2 (Ubuntu Mantic) Assignee: (unassigned) => Athos Ribeiro (athos-ribeiro) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2057576 Title: php-fpm sometimes SIGSEGVs (signal 11) when running fpm_get_status To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/php7.4/+bug/2057576/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Yeah no problem Athos, I feel like maybe you can take it from here. The official fix is not mine and I haven't even tested that one so I don't think I'm needed here.

[Bug 2057576] Re: php-fpm sometimes SIGSEGVs (signal 11) when running fpm_get_status
Hey Lars, I guess I missed you on IRC (sry). To answer your question, yes, since we do have an upstream patch available, it would be better to just go ahead and backport that one! Not that it is any better or than your own patch. It is just easier to deal with changes on the same file/function/line in the future if we stick with those upstream changes! -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2057576 Title: php-fpm sometimes SIGSEGVs (signal 11) when running fpm_get_status To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/php7.4/+bug/2057576/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 2057576] Re: php-fpm sometimes SIGSEGVs (signal 11) when running fpm_get_status
Great! All we need for SRUs should be described in https://wiki.ubuntu.com/StableReleaseUpdates. We can start with filling the SRU bug template, as described in https://wiki.ubuntu.com/StableReleaseUpdates#SRU_Bug_Template. We want to re-write the bug description to include all those fields described there. For the debdiff, you can fetch the patch from https://github.com/php/php- src/commit/df259f88daaf7df5673fd78a0a1b76a1d831d0a2.patch and add some dep3 headers to it (https://dep-team.pages.debian.net/deps/dep3/). If you need help with anything, feel free to ask here or in IRC (you will find me in Libera, in #ubuntu-devel or #ubuntu-server (nickname: athos).

Yeah sure I can try if you're willing to help.

[Bug 2057576] Re: php-fpm sometimes SIGSEGVs (signal 11) when running fpm_get_status
Nice catch, Lars :) Apparently this had been around for a while and was fixed upstream a few months ago: https://github.com/php/php-src/commit/df259f88daaf7df5673fd78a0a1b76a1d831d0a2 Since you did all the work here so far, would you like to drive the SRU by providing debdiffs for mantic, jammy, and focal (they are all affected) and filing the SRU paperwork? I would be happy to guide you through the process in case you are not familiar with it and would sponsor (upload) the patches on your behalf. Otherwise, I will be happy to prepare the SRUs myself.

[Bug 2057576] Re: php-fpm sometimes SIGSEGVs (signal 11) when running fpm_get_status
I think I've found what causes the SIGSEGV, see line 59 in
sapi/fpm/fpm/fpm_status.c: It uses scoreboard_p after it checks it for
NULL
57scoreboard_p = fpm_scoreboard_acquire(NULL, 1);
58if (!scoreboard_p) {
59zlog(ZLOG_NOTICE, "[pool %s] status: scoreboard already in
use.", scoreboard_p->pool); // scoreboard_p is NULL here
60return -1;
61}
Hope this helps.

I've tested on another 20.04.6 and I could reproduce it, here's what I did: place this php script somewhere accessible for web-server & php-fpm: http://localhost/status.php after a couple of seconds SIGSEGV warnings started to appear in the php- fpm log. ** Changed in: php7.4 (Ubuntu) Status: Incomplete => New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2057576 Title: php-fpm sometimes SIGSEGVs (signal 11) when running fpm_get_status To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/php7.4/+bug/2057576/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Hi Lars, Thanks for taking the time to report this bug and help making Ubuntu better. I suppose you are able to reproduce the issue constantly then? Would you mind providing a short (reliable) reproducer for the issue I could use to verify and investigate from a fresh Ubuntu 20.04 installation? I am setting this bug status as incomplete.
