Package: multipath-tools
Version: 0.4.7-1
Severity: grave
Justification: renders package unusable
There are several problems in the current version that are fixed in the
git tree. I have personally encountered some, but not all, of these.
Here are snippets from the git logs that document these:

[libcheckers] workaround for rather profound path checking issue
Overloaded storage response time can be very long.
SG_IO timouts after DEF_TIMEOUT milliseconds, and checkers
interprets this
as a path failure. multipathd then proactively evicts the path from
the DM
multipath table in this case.
This generaly snow balls and ends up in full eviction and IO errors
for end
users. Bad. This may also cause SCSI bus resets, causing disruption
for all
local and external storage hardware users.
Provision a long timeout. Longer than any real-world application would cope
with.
If someone can suggest a real fix, like an evidence the ioctl timed out,
voice up. The ioctl being blocking, I'd rather lower the timeout and retry
than apply this workaround.

[libmultipath] push WWID_SIZE to 128
64 was too small for "scsi_id -p 0x80" in most cases.
As a consequence, the tools refuse to get the uid at all and the path was
discarded ... which is still the good behaviour.
The problem tracking was done by Tarik Sedlarevic, Visionbytes.

[libmultipath] fix segfault when no config file
Brian Wong noticed the segfault and tracked it down to free_keywords()
trying to walk a NULL keywords vector. Credits.

[multipath] cosmetical fix
I'd like to ask some cosmetical fix in libmultipath.
In Redhat /etc/rc.sysinit calls /sbin/multipath -v 0 after modprobe
dm-multipath to catch the disks already attached.
Now it prints a small garbage on screen for every map, I think.
Actually every multipath -F; multipath/multipath -v 0 sequence does
that.
The reason is neither print_multipath_topology nor
snprint_multipath_topology initialize buff if verbosity is 0.
