All custom binaries are built with the wrong contents in the /proc/version_signature file. _all_ custom binaries report the same unchanging version, which is both not for their flavour and not the right base version:
$ uname -a && cat /proc/version_signature
Linux ip-10-36-7-174 2.6.24-29-xen #1 SMP Thu Apr 21 20:44:30 UTC 2011 i686 GNU/Linux
Ubuntu 2.6.24-4.6-generic |
All custom binaries are built with the wrong contents in the /proc/version_signature file. _all_ custom binaries report the same unchanging version, which is both not for their flavour and not the right base version:
$ uname -a && cat /proc/version_signature
Linux ip-10-36-7-174 2.6.24-29-xen #1 SMP Thu Apr 21 20:44:30 UTC 2011 i686 GNU/Linux
Ubuntu 2.6.24-4.6-generic
This leads to great confusion identifying the kernel, which is particularly serious on -xen where the kernel can come from outside the domU. |

This leads to great confusion identifying the kernel, which is particularly serious on -xen where the kernel can come from outside the domU. |
SRU Justification:
Impact: all binary-custom kernels including those in EC2 report an incorrect and very old kernel version via /proc/version_signature
Fix: see patch attached below
Testcase: compare the contents of /proc/version_signature to uname -a
