Title:
Autofs parameter substitution broken in kernel 4.4.0-38 and 4.4.0-40
Status in linux package in Ubuntu:
In Progress
Bug description:
Hello,
I have run into a bug relating autofs's parameter substitution (e.g.
UID, GID, etc) with kernel versions 4.4.0-38 and proposed 4.4.0-40.
Kernel version 4.4.0-28 does things correctly but testing intermediate
kernel versions is hard due to earlier bugs related with fs's.
Incorrect parameter substitution makes CIFS mounting with variable
credentials impossible.
Wat was expected:
$UID in autofs map are substituted by the uid of the user that starts the
auto-mounting process.
What actually happens:
Root's uid (0) is substituted instead.
This ill parameter substitution likely caused by recent fixes
resolving permissions problems for nfs/cifs mounts and dfs referrals
(#1626112 and #1612135). And possibly the fix 'fs: Call d_automount
with the filesystems creds' but that is a wild guess.
Furthermore; playing with the force_standard_program_map_env settings
in autofs.conf and prefixing variables with 'AUTOFS_' does not solve
anything.
Yours kindly,
Chris
