[Kernel-packages] [Bug 2007286] Re: Ubuntu does not clean out old kernel module files (in /lib/modules) when old kernels are removed

[DigiAngel]

Same here...none of these commands remove the old /lib/modules/ kernel
dirs:

sudo apt-get clean
sudo apt-get autoclean
sudo apt-get autoremove
sudo apt-get purge

  == SRU Justification ==
  Commit 87cdf3148b11 fixes a regression introduced by commit
  5efec5c655dd.  However, it has not never landed in Bionic.   Requesting
  this commit in Bionic, so we don't have to wait for it to come down from
  upstream stable.

  
  == Fix ==
  87cdf3148b11 ("xfrm: Verify MAC header exists before overwriting 
eth_hdr(skb)->h_proto")

  == Regression Potential ==
  Low.  This commit fixes and existing regression by making sure teh MAC
  header exists.

  == Test Case ==
  A test kernel was built with this patch and tested by the original bug 
reporter.
  The bug reporter states the test kernel resolved the bug.


  
  Hello,

  After a few days of troubleshooting a problem with L2TP and IPSec a
  fellow from ServerFault pointed out that my problem is a known bug
  fixed by  87cdf3148b11 commit which wasn't backported on 4.15 kernel.

  Ubuntu 4.15.0-36.39-generic 4.15.18
