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. -- Edit bug report at https://bugs.php.net/bug.php?id=80669&edit=1 -- Fix committed: https://bugs.php.net/fix.php?id=80669&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=80669&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=80669&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=80669&r=needscript Try newer version: https://bugs.php.net/fix.php?id=80669&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=80669&r=support Expected behavior: https://bugs.php.net/fix.php?id=80669&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=80669&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=80669&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=80669&r=globals PHP version support discontinued: https://bugs.php.net/fix.php?id=80669&r=phptooold Daylight Savings: https://bugs.php.net/fix.php?id=80669&r=dst IIS Stability: https://bugs.php.net/fix.php?id=80669&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=80669&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=80669&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=80669&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=80669&r=mysqlcfg
