Subject: [PATCH] multipathd: Fix miscounting active paths
When multipathd gets a change uevent, it calls pathinfo with DI_NOIO.
This sets the path state to the return value of path_offline(). If a
path is in the PATH_DOWN state but path_offline() returns PATH_UP, when
that path gets a change event, its state will get moved to PATH_UP
without either reinstating the path, or reloading the map. The next
call to check_path() will move the path back to PATH_DOWN. Since
check_path() simply increments and decrements nr_active instead of
calculating it based on the actual number of active paths, nr_active
will get decremented a second time for this failed path, potentially
putting the multipath device into recovery mode.
This commit does two things to avoid this situation. It makes the
DI_NOIO flag only set pp->state in pathinfo() if DI_CHECKER is also set.
This isn't set in uev_update_path() to avoid changing the path state in
this case. Also, to guard against pp->state getting changed in some
other code path without properly updating the map state, check_path()
now calls set_no_path_retry, which recalculates nr_active based on the
actual number of active paths, and makes sure that the queue_if_no_path
value in the features line is correct.

Subject: [PATCH] multipathd: avoid null pointer dereference in LOG_MSG
LOG_MSG() will dereference pp->mpp. Commit cb5ec664 added a call to
LOG_MSG() before the check for (!pp->mpp) in check_path. This can cause
multipathd to crash. LOG_MSG() should only be called if pp->mpp is set
and a checker is selected.
Also, checker_message() should fail to a generic message if c->cls isn't
set (which means that a checker hasn't been selected).
Fixes: cb5ec664 (multipathd: check_path: improve logging for "unusable
path" case)

Subject: [PATCH] multipathd: ignore failed wwid recheck
If disable_changed_wwids is set, when multipathd gets a change event on
a path, it verifies that the wwid hasn't changed in uev_update_path().
If get_uid() failed, uev_update_path treated this as a wwid change to 0.
This could cause paths to suddenly be dropped due to an issue with
getting the wwid. Even if get_uid() failed because the path was down,
it no change uevent happend when it later became active, multipathd
would continue to ignore the path. Also, scsi_uid_fallback() clears the
failure return if it doesn't attempt to fallback, causing get_uid()
to return success, when it actually failed.
Multipathd should neither set nor clear wwid_changed if get_uid()
returned failure. Also, scsi_uid_fallback() should retain the old return
value if it doesn't attempt to fallback.

Subject: [PATCH] libmutipath: continue to use old state on PATH_PENDING
When pathinfo() sets pp->state to PATH_PENDING, it can cause problems
with path checking. It should act more like check_path(). When
check_path() sees a new state of PATH_PENDING, it doesn't update the
path state at all, so a path's old state is normally never PATH_PENDING.
As and example of the problems of setting a path to PATH_PENDING, If
check_path() sets a path's state to PATH_UP, then a call to pathinfo()
sets the state to PATH_PENDING, and then another call the check_path()
sets the state to PATH_DOWN, multipathd won't fail the path in the
kernel. Also, if a path's state is PATH_PENDING, and nr_active is
recalculated, that path will count as down, even if the state was
previously PATH_UP. If a path already has a state of PATH_WILD or
PATH_UNCHECKED, changing it to PATH_PENDING won't hurt anything, and it
will help anyone who sees it know what's actually happening. But
otherwise, pathinfo() should leave the previous state alone.

reload_map() doesn't do the work to sync the state after reloading the
map. Instead of calling it directly, cli_reload() and uev_update_path()
should call update_path_groups(), which calls reload_map() with all the
necessary syncing.

Subject: [PATCH] libmulitpath: cleanup uid_fallback code
Instead of always calling uid_fallback() if the configured method to get
the uid failed, get_uid now checks if the path supports fallbacks and if
all the retriggers have occurred. If so, it calls uid_fallback(), which
just attempts to get the uid using the appropriate fallback method. None
of these changes should make the code function any differently.

Subject: [PATCH] multipathd: handle changed wwids by removal and addition
If a path's WWID changes, it's not necessarily failed. But it certainly
has to be removed from an existing map, otherwise data corruption is
imminent. Instead of keeping the path in the map, failing it, and
remembering the "changed WWID" state, this patch simply removes and
re-adds the path.
This is patch is heavily based on the previous patch of the same name
by Martin Wilck.

Subject: [PATCH] multipathd: Don't use fallback code after getting wwid
The fallback code is necessary to set up mutipath devices, if multipath
temporarily can't get the information from udev. However, once the
devices are set up, udev is the definitive source of this information.
The wwid gotten from the fallback code and the udev code should always
be the same, in which case it doesn't matter where we get the wwid
from. But if they are different, it's important to try to do the
right thing.
Working under the assumption that udev will either never give us this
information, or that it usually will. multipath should assume that if
there are multiple paths to a device, either they will all never get
a wwid from udev, or some of them will likely already have gotten the
correct wwid from udev. In this case, we should fix this as soon as
possible.
This does mean that devices where udev will never give out the uuid
will not notice if the wwid changes, but that's a small price to pay
for doing the right thing most of the time.
