-Subject: autofs: Fix automounts by using current_real_cred()->uid
-
-Seth Forshee reports that in 4.8-rcN some automounts are failing
-because the requesting the automount changed.
-
-The relevant call path is:
-follow_automount()
- ->d_automount
- autofs4_d_automount
- autofs4_mount_wait
- autofs4_wait
-
-In autofs4_wait wq_uid and wq_gid are set to current_uid() and
-current_gid respectively. With follow_automount now overriding creds
-uid that we export to userspace changes and that breaks existing
-setups.
-
-To remove the regression set wq_uid and wq_gid from
-current_real_cred()->uid and current_real_cred()->gid respectively.
-This restores the current behavior as current->real_cred is identical
-to current->cred except when override creds are used.
