Bug #80669 [NEW]: Can't initgroups() when specifying numeric user
From: andreas dot ley at kit dot edu
Operating system: Debian GNU/Linux
PHP version: Irrelevant
Package: *Configuration Issues
Bug Type: Bug
Bug description:Can't initgroups() when specifying numeric user
Description:
------------
When using PHP-FPM, you can configure the "user" directive for a pool
with either an (alphanumeric) username or a (numeric) uid. However, if
you do the latter, initgroups() won't set supplementary groups.
This is due to fpm_unix_init_child() in sapi/fpm/fpm/fpm_unix.c calling
"initgroups(wp->config->user, wp->set_gid)".
One possible solution would be changing this to "initgroups(wp->user,
wp->set_gid)" which would require to set wp->user from
getpwuid(wp->set_uid) in fpm_unix_conf_wp() in the very same file, which
currently is only done when is_root is false.
One objection could be that a uid might not be unique, but the same
applies to the non-root case. Another possibility then might be an
explicit configuration directive for supplementary groups.
If you decide to go for the first solution, I'd volunteer to write a
patch for that upon request.
