I can confirm that using 4.4.0-47.68 version has resolved the autofs
problem.

  SRU Justification

  Impact: ca6fe3344554 "fs: Call d_automount with the filesystems creds"
  causes a regression in the requester uid and gid passed to userspace
  during automount, as the current credentials during automount are
  those of root and not the user who requested the mount.

  Fix: Use current->real_cred instead of current->cred for getting the
  requester's uid and gid.

  Regression Potential: Minimal. current->cred and current->real_cred
  are the same except when credentials are overridden, thus
  current->real_cred contains the same credentials that autofs had been

  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

An update on comment #30 - the security update has put
testing/verification behind schdule, so the release date for the
-proposed kernel has been pushed back a week to Nov 7. Apologies for the
inconvenience.

[Kernel-packages] [Bug 1629204] Re: Autofs parameter substitution broken in kernel 4.4.0-38 and 4.4.0-40

[Seth Forshee]

The recent update was outside of the normal SRU release cycle to fix a
serious security issue and contained only the security fix. There is a
new -proposed kernel (4.4.0-46.67) which contains the fix for this bug,
and barring any other unforeseen circumstances it will be released
according to the original SRU schedule, on Oct 31.

[Kernel-packages] [Bug 1629204] Re: Autofs parameter substitution broken in kernel 4.4.0-38 and 4.4.0-40

[Robert Euhus]

This is unbelieveable:

- Ubuntu Xenial is shipping new broken kernels with a known REGRESSION !

- For more than two weeks a fix is known and "InProgress" (whatever this
means). That does however not prevent new broken kernels from being
released (4.4.0-42 and 4.4.0-43).

- Moreover all of these broken kernels have never gone through
-proposed. Isn't this what -proposed is supposed to be for?!?

- For about a day a fixed and approved kernel (4.4.0-44) has finally
made it to -proposed. But this again does not prevent another broken
kernel (4.4.0-45) to be released directly, without going through
-proposed.

- And to top it all, the git repo does not seem to be up to date.
git://kernel.ubuntu.com/ubuntu/ubuntu-xenial.git

I am really pissed!

  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

[Kernel-packages] [Bug 1629204] Re: Autofs parameter substitution broken in kernel 4.4.0-38 and 4.4.0-40

[Torsten Casselt]

Are you serious? You release a new kernel 4.4.0-45 without the fixes in
4.4.0-44 sitting in -proposed? What do you think -proposed is meant for?
Systems using -proposed to avoid this bug now happily boot the new
kernel facing this bug again.

Could you please get your stuff together and stop breaking
installations?! Why do you think people are using LTS releases?

[Kernel-packages] [Bug 1629204] Re: Autofs parameter substitution broken in kernel 4.4.0-38 and 4.4.0-40

[Seth Forshee]

This bug is awaiting verification that the kernel in -proposed solves
the problem. Please test the kernel and update this bug with the
results. If the problem is solved, change the tag 'verification-needed-
xenial' to 'verification-done-xenial'.

If verification is not done by 5 working days from today, this fix will
be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how
to enable and use -proposed. Thank you!

  Autofs parameter substitution broken in kernel 4.4.0-38 and 4.4.0-40

  SRU Justification

  Impact: ca6fe3344554 "fs: Call d_automount with the filesystems creds"
  causes a regression in the requester uid and gid passed to userspace
  during automount, as the current credentials during automount are
  those of root and not the user who requested the mount.

  Fix: Use current->real_cred instead of current->cred for getting the
  requester's uid and gid.

  Regression Potential: Minimal. current->cred and current->real_cred
  are the same except when credentials are overridden, thus
  current->real_cred contains the same credentials that autofs had been
  using prior to the change which overrides the credentials during
  automount.

  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

[Seth Forshee]

Unfortunately there was a delay getting new kernels out to -proposed,
but 4.4.0-44.64 has been built in the canonical-kernel-team PPA and does
have the fix. This kernel should be migrated to -proposed soon, but you
can download it directly from the PPA too (I don't recommend subscribing
to that PPA however).

[Kernel-packages] [Bug 1629204] Re: Autofs parameter substitution broken in kernel 4.4.0-38 and 4.4.0-40

[Robert Euhus]

I really don't understand what's going on here. It's been another 6 days
now. There has been another (broken) kernel update for xenial (4.4.0-43)
which did not include this fix, and which also did not go through
-proposed. Instead xenial-proposed is still at at 4.4.0-41, which is
broken as well.

Two "stable" kernel updates with a known regression and a simple fix.

How is this possible?

And how does this fit with xenial being an LTS-Release?

This really ain't funny any more!

For now I have build the packages with the fix applied for amd64 and
I'll try to keep up with new broken kernels. In case anybody else needs
them:

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 89C9B5AE
sudo apt-add-repository -u 'http://ubuntu.repo.uni-hannover.de/ubuntu xenial 
pub'
Or get the key from here: 
http://ubuntu.repo.uni-hannover.de/ubuntu/luh-deb-repo.gpg.key

There will be a new kernel in -proposed in the next day or two which
will include the fix.

I am very disappointed that another broken "stable" kernel (4.4.0-42.62)
was just released for xenial, even though this problem and the fix have
been known for about a week!

Why?

What can I do to speed up the progress?

I really need a working kernel on xenial! Or do I have to build it
myself and roll it out to our systems?

Thanks,
Robert.

  SRU Justification

  Impact: ca6fe3344554 "fs: Call d_automount with the filesystems creds"
  causes a regression in the requester uid and gid passed to userspace
  during automount, as the current credentials during automount are
  those of root and not the user who requested the mount.

  Fix: Use current->real_cred instead of current->cred for getting the
  requester's uid and gid.

  Regression Potential: Minimal. current->cred and current->real_cred
  are the same except when credentials are overridden, thus
  current->real_cred contains the same credentials that autofs had been
  using prior to the change which overrides the credentials during
  automount.

  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

[Kernel-packages] [Bug 1629204] Re: Autofs parameter substitution broken in kernel 4.4.0-38 and 4.4.0-40

[Robert Euhus]

I can confirm that the 0001-autofs4-Use-real_cred-for-uid-gid-in-
packets.patch fixes the problem.

I have tried the kernel located here:
http://people.canonical.com/~sforshee/lp1629204/

And I have also applied the patch an top of the 4.4.0-38 kernel (commit
be687e48ba9778ab2f28513bd50e1b274ba31f68) this fixes the problem there
as well.

Please release a fixed kernel for xenial asap!

Thanks to everyone involved.

Regards
Robert.

  causes a regression in the requester uid and gid passed to userspace
  during automount, as the current credentials during automount are
  those of root and not the user who requested the mount.

  Fix: Use current->real_cred instead of current->cred for getting the
  requester's uid and gid.

  Regression Potential: Minimal. current->cred and current->real_cred
  are the same except when credentials are overridden, thus
  current->real_cred contains the same credentials that autofs had been
  using prior to the change which overrides the credentials during
  automount.

  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

[Chris van Run]

@Seth - thanks for the quick build. Keep up the good work. Seems like a
simple enough patch though =D.

After testing it I can confirm the patch works! Autofs parameters are
once again correctly substituted in kernel version 4.4.0-40 (60).

Cheers,

Chris

Title:
  Autofs parameter substitution broken in kernel 4.4.0-38 and 4.4.0-40

Status in linux package in Ubuntu:
  Incomplete

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

[Chris van Run]

You can easily check this bug by:

1 setting logging in autofs.conf to 'debug'
2 create a simple autofs map:

   /etc/auto.master:
/mnt/test auto.test

   /etc/auto.test:
root -fstype=autofs,uid=$UID,gid=$GID :/dev/sda1

3 look at journalctl -xfe --unit autofs output while with a non-root
user trying to navigate to /mnt/test/root. Especially the log lines with
parse_mount: parse(sun).
