Subject: [PATCH] Allow negative uids/gids in PolkitUnixUser and Group objects
|
||||
|
||||
(uid_t) -1 is still used as placeholder to mean "unset". This is OK, since
|
||||
there should be no users with such number, see
|
||||
https://systemd.io/UIDS-GIDS#special-linux-uids.
|
||||
|
||||
(uid_t) -1 is used as the default value in class initialization.
|
||||
|
||||
When a user or group above INT32_MAX is created, the numeric uid or
|
||||
gid wraps around to negative when the value is assigned to gint, and
|
||||
polkit gets confused. Let's accept such gids, except for -1.
|
||||
|
||||
A nicer fix would be to change the underlying type to e.g. uint32 to
|
||||
not have negative values. But this cannot be done without breaking the
|
||||
API, so likely new functions will have to be added (a
|
||||
polkit_unix_user_new variant that takes a unsigned, and the same for
|
||||
_group_new, _set_uid, _get_uid, _set_gid, _get_gid, etc.). This will
|
||||
require a bigger patch.
|
||||
|
||||
Fixes https://gitlab.freedesktop.org/polkit/polkit/issues/74.
