Title:
[Precise] drbd8: drbdadm does not run compat mode when
DRBD_DONT_WARN_ON_VERSION_MISMATCH is set
Status in “drbd8” package in Ubuntu:
Invalid

Bug description:
SRU Justification:
Impact: This is for now only relevant for the 12.04 (Precise) backport
of drbd-utils 8.4.x as that uses the 8.3 compat mode when running with
a linux kernel module from kernel 3.2.x. Problem is the following
code:
if (!getenv("DRBD_DONT_WARN_ON_VERSION_MISMATCH"))
warn_on_version_mismatch();
maybe_exec_drbdadm_83(argv);
Because maybe_ecec_drbdadm_83 relies on a structure being filled in
warn_on_version_mismatch only.
Fix: Add a call to setup the kernel version to maybe_exec_drbdadm_83.
This function does the full setup only once already.
Testcase: When running a 3.2 kernel and the 8.4.x version of
drbd8-utils "drbdadm --version" without
DRBD_DONT_WARN_ON_VERSION_MISMATCH set in the environment, It will
return a 8.3 version number. Otherwise a version 8.4. When the bug is
fixed it has to be a 8.3 version in both cases.
