| | | | | | | | | | On systems without setfsuid(), use setreuid() instead. Authors: Steve Langasek <vorlon@debian.org> Upstream status: to be forwarded, now that pam_modutil_{drop,regain}_priv are implemented Gbp-Pq: Name hurd_no_setfsuid
* libpam: add supplementary groups on priv dropAllison Karlitskaya2020-11-10
| | | | | | | | | | | | | | Replace the setgroups(0, NULL) call in pam_modutil_drop_priv() with a call to initgroups(). This makes sure that the user's supplementary groups are also configured. Fall back to setgroups(0, NULL) in case the initgroups() call fails. This fixes the permission check in pam_motd: this feature was intended to allow setting permissions on a motd file to prevent it from being shown to users who are not a member of a particular group (for example, wheel). Closes #292
