LU-8021 tests: In interop, ensure to save/restore correct debug flags

debugsave() and debugrestore() in test-framework.sh save the
same debug flags of the client on servers as well.

In case of interop, esp between lustre 2.1.x server and
2.5.x clients, with PTLDEBUG=-1 the debugrestore() would fail as
there are some flags which are newly added to 2.5.x,
    e.g. "lfsck, hsm" are not defined on 2.1.x servers.

- The fix, makes sure to save the debug flags for servers and clients
separately and thus restore correctly.

- It restores the debug flags irrespective of, if the server node
is active or passive, failover node.

- It takes care,
if any of the node(server OR client) is down or unreachable,
if there are separate MDS MGS servers,
if any of the node is rebooted (FAILURE_MODE=hard)
but lustre modules are not loaded.

Also, there is defect introduced by LU-4480 in reset_fail_loc,
this patch fixes that as well.

LU-7782 scrub: handle slave obj of striped directory

When lookup item under striped directory, we need to locate the
master MDT-object of the striped directory firstly, then the
client will send lookup (getattr_by_name) RPC to the MDT with
some slave MDT-object's FID and the item's name. If the system
is restored from MDT file level backup, then before the OI scrub
completely built the OI files, the OI mappings of the master
MDT-object and slave MDT-object may be invalid. Usually, it is
not a problem for the master MDT-object. Because when locate the
master MDT-object, we will do name based lookup (for the striped
directory itself) firstly, during such process we can setup the
correct OI mapping for the master MDT-object. But it will be
trouble for the slave MDT-object. Because the client will not
trigger name based lookup on the MDT to locate the slave
MDT-object before locating item under the striped directory,
then when osd_fid_lookup(), it will find that the OI mapping
for the slave MDT-object is invalid and does not know what the
right OI mapping is, then the MDT has to return -EINPROGRESS to
the client to notify that the OI scrub is rebuiding the OI file,
related OI mapping is unknown yet, please try again later. And
then client will re-try the RPC again and again until related
OI mapping has been updated. That is quite inefficient.

To resolve above trouble, we will handle it as the following
two cases:

1) The slave MDT-object and the MDT-object are on different
   MDTs. It is relative easy. Be as one of remote MDT-objects,
   the slave MDT-object is linked under /REMOTE_PARENT_DIR
   with the name of its FID string. We can locate the slave
   MDT-object via lookup the /REMOTE_PARENT_DIR directly.

2) The slave MDT-object and the MDT-object reside on the same
   MDT. Under such case, during lookup the master MDT-object,
   we will lookup the slave MDT-object via readdir the master
   MDT-object, because the slave MDT-objects information are
   stored as sub-directories with the name "${FID}:${index}".
   Then when find the local slave MDT-object, its OI mapping
   will be recorded. Then subsequent osd_fid_lookup() will
   know the correct OI mapping for the slave MDT-object.

The patch also enhance sanity-scrub to avoid DNE in sanity-scrub
on one MDT.

LU-7702 ldlm: skip lock if export failed

This patch resolves IO vs eviction race.
After eviction failed export stayed at stale list,
a client had IO processing and reconnected during it.
A client sent brw rpc with last lock cookie and new connection.
The lock with failed export was found and assert was happened.
(ost_handler.c:1812:ost_prolong_lock_one())
ASSERTION( lock->l_export == opd->opd_exp ) failed:

1. Skip the lock at ldlm_handle2lock if lock export failed.
2. Validation of lock for IO was added at hpreq_check(). The lock
   searching is based on granted interval tree. If server doesn`t
   have a valid lock, it reply to client with ESTALE.
3. A lock prolong was moved at ldlm layer.

LU-5614 build: use %kernel_module_package in rpm spec

Replace module packages definitions with calls to the vendor defined
%kernel_module_package macro.  This results in many of the rpm packages
changing names from what we are used to in the past.  Each Linux
distribution may name the modules packages slightly differently, most
notably RHEL and SLES choose different naming schemes.  The
%kernel_module_package macro handles these details for us.

For instance, on RHEL7 the packages that contain lustre's kernel modules
become:

  kmod-lustre             (previously in "lustre-modules" package)
  kmod-lustre-osd-ldiskfs (previously in "lustre-osd-ldiskfs" package)
  kmod-lustre-osd-zfs     (previously in "lustre-osd-zfs" package)
  kmod-lustre-tests       (previously in "lustre-tests" package)

On SLES12, the same packages are instead named:

  lustre-kmp-default
  lustre-osd-ldiskfs-kmp-default
  lustre-osd-zfs-kmp-default
  lustre-tests-kmp-default

These kernel module packages give us what is known as "weak-updates".
Instead of compiling Lustre for every minor kernel that is installed,
the weak-updates will automatically symlink the Lustre modules into
and kernel's modules subdirectories if that kernel offers the required
kernel symbols with exactly the same symbol versions.

In addition to changing the package names for all of the Lustre packages
containing kernel modules, the location of the modules in /lib/modules
changes as well.  Each package will put its modules in a subdirectory
matching part of the package name itself (required by the macros on RHEL
systems).  The path name is also different on RHEL and SLES systems
(e.g. "extra" vs. "updates").

Some further path examples are:

  RHEL7, kmod-lustre package:
    /lib/modules/3.10.0-327.18.2.el7_lustre.x86_64/extra/lustre/fs/ost.ko

  SLES12, lustre-kmp-default package:
    /lib/modules/3.12.57-60.35_lustre-default/updates/lustre/fs/ost.ko

  RHEL7, kmod-lustre-osd-ldiskfs package:
    /lib/modules/3.10.0-327.18.2.el7_lustre.x86_64/extra/lustre-osd-ldiskfs/fs/osd_ldiskfs.ko

  SLES12, lustre-osd-ldiskfs-kmp-default package:
    /lib/modules/3.12.57-60.35_lustre-default/updates/lustre-osd-ldiskfs/fs/osd_ldiskfs.ko

LU-7418 tests: avoid background writeout in sanity 29

Intermittent failures of sanity.sh test_29 are caused by background
writeout starting (or continuing) after the MDC DLM locks were
cancelled, requiring the layout lock to be re-fetched from the MDS.
Cancelling the DLM locks via "lru_size=clear" is not enough, since
this will not cancel any locks that are currently in use.

Instead, ensure that all the dirty pages from previous tests are
written out so that no new writes are started during the test.

LU-8220 tests: stripe file over all active OSTs

In test_iozone/parallel-scale-cifs, the iozone command creates the
temporary files under test with default stripe count=1, that is,
both the 256mb files reside on the same OST, over-utilizing the OST,

The fix is to create a sub-directory in the samba server mount
point with a stripe count of -1 (stripe over all available OSTs)
and then run iozone with this sub-directory path, so that all the
temporary files created within this sub-directory, during iozone,
reside on multiple OSTs and OST free space is utilized uniformly.

Since the test suite mounts lustre client on smb server, the "lfs
setstripe" command is executed on the smb server.

LU-7004 utils: remove "lctl conf_param" deprecation

The "lctl set_param -P" functionality was intended to replace
"lctl conf_param" with a more uniform interface that matches
the existing "lctl set_param" and "lctl get_param" usage.
However, there are still unresolved issues that need to be
addressed and a longer transition period needed before the
old functionality can be removed.

Remove the deprecation warning for now, rather than bumping it
to some later release.  It can be re-added when "set_param -P"
has been fixed.

LU-7434 ptlrpc: lost bulk leads to a hang

This is a combination of two commits. The original commit from:
http://review.whamcloud.com/17221
and a fix to that commit from:
http://review.whamcloud.com/19758

Description of the original patch:
The reverse order of request_out_callback() and reply_in_callback()
puts the RPC into UNREGISTERING state, which is waiting for RPC &
bulk md unlink, whereas only RPC md unlink has been called so far.
If bulk is lost, even expired_set does not check for UNREGISTERING
state.

The same for write if server returns an error.

This phase is ambiguous, split to UNREG_RPC and UNREG_BULK.

The fix to the original commit was originally pushed against LU-8062.
That fix is described thusly:
LU-8062 test: fix fail_val in recovery-small/115b

The fail_loc OBD_FAIL_OST_ENOSPC is caught in 2 places:
1. ofd_statfs() - where it is checked against the fail_val
and if fail_val matches the OST ID it is caught here
itself and hence test fails.
2. tgt_brw_write() - the actual place where the fail_loc should
be caught.

The patch makes the fail_loc to be caught at the appropriate place
by setting the fail_val to $OSTCOUNT. So even if fail_loc is set
in the statfs part it is not caught there and therefore caught in
tgt_brw_write().

Please note the author of the original patch was Vitaly Fertman
<vitaly.fertman@seagate.com>, and the author of the test fix was

llog could store infinite number of records and limited by

This fix changes type u32 to u64 for *id. Now, we store only

LU-7334 lprocfs: Allow a new line before null terminator

Kernel string parsing functions support a single new line
before the null terminator of a string. Our numeric string
parsing should do the same. This allows strings to be
echo'ed directly into proc files.
