Bug description:
  Setting net.ipv4.neigh.default.gc_thresh1/2/3 on the 3.13.0-96-generic
  kernel and below worked fine using the following:

  $ sudo /sbin/sysctl -w net.ipv4.neigh.default.gc_thresh1=128
  128

  As of 3.13.0-97-generic, though, it no longer works as expected:

  $ sudo /sbin/sysctl -w net.ipv4.neigh.default.gc_thresh1=128
  error: "Invalid argument" setting key "net.ipv4.neigh.default.gc_thresh1"

  There are two potentially related revisions in the -97 release -
  http://kernel.ubuntu.com/git/ubuntu/ubuntu-precise.git/commit/?h=lts-
  backport-trusty=563cf19389d8e999e69d6c94995966aeaf7c3a08 and
  http://kernel.ubuntu.com/git/ubuntu/ubuntu-precise.git/commit/?h=lts-
  backport-trusty=7b82096b0ebc9bf487b390fe970d66ffa5a5774e.

  The expected behavior is that changing neighbor table settings works
  using 'sysctl -w' with the same values as before the -97 kernel.

  Setting net.ipv4.neigh.default.gc_thresh1/2/3 on the 3.13.0-96-generic
  kernel and below worked fine using the following:

  $ sudo /sbin/sysctl -w net.ipv4.neigh.default.gc_thresh1=128
  128

  As of 3.13.0-97-generic, though, it no longer works as expected:

  $ sudo /sbin/sysctl -w net.ipv4.neigh.default.gc_thresh1=128
  error: "Invalid argument" setting key "net.ipv4.neigh.default.gc_thresh1"

  There are two potentially related revisions in the -97 release -
  http://kernel.ubuntu.com/git/ubuntu/ubuntu-precise.git/commit/?h=lts-
  backport-trusty=563cf19389d8e999e69d6c94995966aeaf7c3a08 and

  The expected behavior is that changing neighbor table settings works

[Kernel-packages] [Bug 1634892] Re: Setting net.ipv4.neigh.default.gc_thresh1/2/3 on 3.13.0-97.144 or later causes 'invalid argument' error

[Brad Figg]

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-
trusty' to 'verification-done-trusty'. If the problem still exists,
change the tag 'verification-needed-trusty' to 'verification-failed-
trusty'.

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!

  There are two potentially related revisions in the -97 release -
  http://kernel.ubuntu.com/git/ubuntu/ubuntu-precise.git/commit/?h=lts-
  backport-trusty=563cf19389d8e999e69d6c94995966aeaf7c3a08 and

  The expected behavior is that changing neighbor table settings works
  using 'sysctl -w' with the same values as before the -97 kernel.

What is the current planned release date of this kernel? We also have
issues that we must solve and downgrading is not really an option.

[Thomas Copeland]

Looks like this got punted to 3.13.0-106, which I installed it from the
canonical-kernel-team ppa. This bug appears to be solved in -106.

thomasco@dev:~$ uname -a

[Hajo Locke]

When this fix will appear in official kernel-release?
Yesterday i updated Trusty Tahr/14.04 to 3.13.0-103-generic and this problem is 
still present.
This is a problem for all people who use 14.04 in high frequented environments, 
just like nameservers.

Bug description:
  Setting net.ipv4.neigh.default.gc_thresh1/2/3 on the 3.13.0-96-generic
  kernel and below worked fine using the following:

  $ sudo /sbin/sysctl -w net.ipv4.neigh.default.gc_thresh1=128
  128

  As of 3.13.0-97-generic, though, it no longer works as expected:

  $ sudo /sbin/sysctl -w net.ipv4.neigh.default.gc_thresh1=128
  error: "Invalid argument" setting key "net.ipv4.neigh.default.gc_thresh1"

  There are two potentially related revisions in the -97 release -
  http://kernel.ubuntu.com/git/ubuntu/ubuntu-precise.git/commit/?h=lts-
  backport-trusty=563cf19389d8e999e69d6c94995966aeaf7c3a08 and

  backport-trusty=7b82096b0ebc9bf487b390fe970d66ffa5a5774e.

  The expected behavior is that changing neighbor table settings works
  using 'sysctl -w' with the same values as before the -97 kernel.

[Kernel-packages] [Bug 1634892] Re: Setting net.ipv4.neigh.default.gc_thresh1/2/3 on 3.13.0-97.144 or later causes 'invalid argument' error

[Ryan Cox]

Thanks for the quick work on this. Any idea when this fix might land in
the linux-image-generic package?

Bug description:
  Setting net.ipv4.neigh.default.gc_thresh1/2/3 on the 3.13.0-96-generic
  kernel and below worked fine using the following:

  $ sudo /sbin/sysctl -w net.ipv4.neigh.default.gc_thresh1=128
  128

  As of 3.13.0-97-generic, though, it no longer works as expected:

  $ sudo /sbin/sysctl -w net.ipv4.neigh.default.gc_thresh1=128
  error: "Invalid argument" setting key "net.ipv4.neigh.default.gc_thresh1"

  There are two potentially related revisions in the -97 release -
  http://kernel.ubuntu.com/git/ubuntu/ubuntu-precise.git/commit/?h=lts-
  backport-trusty=563cf19389d8e999e69d6c94995966aeaf7c3a08 and

  backport-trusty=7b82096b0ebc9bf487b390fe970d66ffa5a5774e.

  The expected behavior is that changing neighbor table settings works
  using 'sysctl -w' with the same values as before the -97 kernel.

[Kernel-packages] [Bug 1634892] Re: Setting net.ipv4.neigh.default.gc_thresh1/2/3 on 3.13.0-97.144 or later causes 'invalid argument' error

[Joseph Salisbury]

I built another Trusty test kernel. However, this kernel is with a
cherry pick of commit b194c1f1dbd5f2671e49e0ac801b1b78dc7de93b and
without the reverts.

The test kernel can be downloaded from:
http://kernel.ubuntu.com/~jsalisbury/lp1634892/

Can you test this kernel and see if it resolves this bug?

[Joseph Salisbury]

Well that was easy, now that you identified rc6 as working.  I'll be
willing to bet this is the fix:

commit b194c1f1dbd5f2671e49e0ac801b1b78dc7de93b
Author: Jiri Pirko 
Date:   Fri Feb 21 14:52:57 2014 +0100

neigh: fix setting of default gc_* values

This patch fixes bug introduced by:
commit 1d4c8c29841b9991cdf3c7cc4ba7f96a94f104ca
"neigh: restore old behaviour of default parms values"

The thing is that in neigh_sysctl_register, extra1 and extra2 which were
previously set for NEIGH_VAR_GC_* are overwritten. That leads to
nonsense int limits for gc_* variables. So fix this by not touching
extra* fields for gc_* variables.

Bug description:
  Setting net.ipv4.neigh.default.gc_thresh1/2/3 on the 3.13.0-96-generic
  kernel and below worked fine using the following:

  $ sudo /sbin/sysctl -w net.ipv4.neigh.default.gc_thresh1=128
  128

  As of 3.13.0-97-generic, though, it no longer works as expected:

  $ sudo /sbin/sysctl -w net.ipv4.neigh.default.gc_thresh1=128
  error: "Invalid argument" setting key "net.ipv4.neigh.default.gc_thresh1"

  There are two potentially related revisions in the -97 release -
  http://kernel.ubuntu.com/git/ubuntu/ubuntu-precise.git/commit/?h=lts-
  backport-trusty=563cf19389d8e999e69d6c94995966aeaf7c3a08 and

  backport-trusty=7b82096b0ebc9bf487b390fe970d66ffa5a5774e.

  The expected behavior is that changing neighbor table settings works
  using 'sysctl -w' with the same values as before the -97 kernel.

[Joseph Salisbury]

Great, thanks for testing and finding the version!   I'll review the
commit logs for rc6 and see if anything sticks out as the fix.  If not.
we can reverse bisect between rc5 and rc6 to identify the fix.

This sysctl also fails in rc5, so the fix must have landed in rc6.

rc4 has the same problem:

[Kernel-packages] [Bug 1634892] Re: Setting net.ipv4.neigh.default.gc_thresh1/2/3 on 3.13.0-97.144 or later causes 'invalid argument' error

[Joseph Salisbury]

Thanks for testing, Yoshi.  That is good news and means there is a fix
for this already, without requiring a revert.  We just need to narrow
down which version the fix landed in, and then identify that commit.

Lets first test some of the 3.14 release candidates, newer than -rc1.
Can you test the following:

v3.14-rc4: http://kernel.ubuntu.com/~kernel-
ppa/mainline/v3.14-rc4-trusty/

If v3.14-rc4 does NOT exhibit the bug then test v3.14-rc3:
v3.14-rc3: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.14-rc3-trusty/

If v3.14-rc4 DOES exhibit the bug then test v3.14-rc6:
v3.14-rc6: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.14-rc6-trusty/

Thanks!

Bug description:
  Setting net.ipv4.neigh.default.gc_thresh1/2/3 on the 3.13.0-96-generic
  kernel and below worked fine using the following:

  $ sudo /sbin/sysctl -w net.ipv4.neigh.default.gc_thresh1=128
  128

  As of 3.13.0-97-generic, though, it no longer works as expected:

  $ sudo /sbin/sysctl -w net.ipv4.neigh.default.gc_thresh1=128
  error: "Invalid argument" setting key "net.ipv4.neigh.default.gc_thresh1"

  There are two potentially related revisions in the -97 release -
  http://kernel.ubuntu.com/git/ubuntu/ubuntu-precise.git/commit/?h=lts-
  backport-trusty=563cf19389d8e999e69d6c94995966aeaf7c3a08 and
  http://kernel.ubuntu.com/git/ubuntu/ubuntu-precise.git/commit/?h=lts-
  backport-trusty=7b82096b0ebc9bf487b390fe970d66ffa5a5774e.

  The expected behavior is that changing neighbor table settings works
  using 'sysctl -w' with the same values as before the -97 kernel.

Had the same Invalid argument error in 3.14-rc1 as well,
but for 3.15.0-031500, I could set the parameter successfully.

[Kernel-packages] [Bug 1634892] Re: Setting net.ipv4.neigh.default.gc_thresh1/2/3 on 3.13.0-97.144 or later causes 'invalid argument' error

[Joseph Salisbury]

We might need to perform a "Reverse" bisect to identify the fix that
prevented this commit from being reverted in newer kernel versions.

Can you first confirm that the bug also exists in upstream v3.14-rc1?  It can 
be downloaded from:
http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.14-rc1-trusty/

If the bug DOES also exist in v3.14-rc1, then test v3.15:
http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.15-utopic/

We can decide the next step based on the results of these two test.

[Kernel-packages] [Bug 1634892] Re: Setting net.ipv4.neigh.default.gc_thresh1/2/3 on 3.13.0-97.144 or later causes 'invalid argument' error

[Joseph Salisbury]

I built another Trusty test kernel.  However, this kernel is with a
cherry pick of commit 9ecf07a1d8f7 and without the reverts.

The test kernel can be downloaded from:
http://kernel.ubuntu.com/~jsalisbury/lp1634892/

Can you test this kernel and see if it resolves this bug?

  The expected behavior is that changing neighbor table settings works
  using 'sysctl -w' with the same values as before the -97 kernel.

[Kernel-packages] [Bug 1634892] Re: Setting net.ipv4.neigh.default.gc_thresh1/2/3 on 3.13.0-97.144 or later causes 'invalid argument' error

[Joseph Salisbury]

I built a Trusty test kernel with a revert of mainline commit 1d4c8c2.
This also required that I revert commit bba24896f.

The test kernel can be downloaded from:
http://kernel.ubuntu.com/~jsalisbury/lp1634892/

Can you test this kernel and see if it resolves this bug?

  Setting net.ipv4.neigh.default.gc_thresh1/2/3 on the 3.13.0-96-generic
  kernel and below worked fine using the following:

  $ sudo /sbin/sysctl -w net.ipv4.neigh.default.gc_thresh1=128
  128

  As of 3.13.0-97-generic, though, it no longer works as expected:

  $ sudo /sbin/sysctl -w net.ipv4.neigh.default.gc_thresh1=128
  error: "Invalid argument" setting key "net.ipv4.neigh.default.gc_thresh1"

  There are two potentially related revisions in the -97 release -
  http://kernel.ubuntu.com/git/ubuntu/ubuntu-precise.git/commit/?h=lts-
  backport-trusty=563cf19389d8e999e69d6c94995966aeaf7c3a08 and

  backport-trusty=7b82096b0ebc9bf487b390fe970d66ffa5a5774e.

  The expected behavior is that changing neighbor table settings works
  using 'sysctl -w' with the same values as before the -97 kernel.

I've bisected Ubuntu-3.13.0-96.143 to Ubuntu3.13.0-97.144 and it looks
like 7b82096b0ebc9bf487b390fe970d66ffa5a5774e introduced the problem.

neigh: restore old behaviour of default parms values

commit 1d4c8c29841b9991cdf3c7cc4ba7f96a94f104ca upstream.

Previously inet devices were only constructed when addresses are added.
Therefore the default neigh parms values they get are the ones at the
time of these operations.

Now that we're creating inet devices earlier, this changes the behaviour
of default neigh parms values in an incompatible way (see bug #8519).

This patch creates a compromise by setting the default values at the
same point as before but only for those that have not been explicitly
set by the user since the inet device's creation.

Bug description:
  Setting net.ipv4.neigh.default.gc_thresh1/2/3 on the 3.13.0-96-generic
  kernel and below worked fine using the following:

  $ sudo /sbin/sysctl -w net.ipv4.neigh.default.gc_thresh1=128
  128

  As of 3.13.0-97-generic, though, it no longer works as expected:

  $ sudo /sbin/sysctl -w net.ipv4.neigh.default.gc_thresh1=128
  error: "Invalid argument" setting key "net.ipv4.neigh.default.gc_thresh1"

  There are two potentially related revisions in the -97 release -
  http://kernel.ubuntu.com/git/ubuntu/ubuntu-precise.git/commit/?h=lts-
  backport-trusty=563cf19389d8e999e69d6c94995966aeaf7c3a08 and

  backport-trusty=7b82096b0ebc9bf487b390fe970d66ffa5a5774e.

  The expected behavior is that changing neighbor table settings works
  using 'sysctl -w' with the same values as before the -97 kernel.
