LU-6356 gss: call out info must include 'self nid'

When using interconnect different from eth, svc_princ_verify_host()
fails because remote node uses nid of target to build principal host
information.
Call out info must include a self nid so that svc_princ_verify_host()
can successfully match the host info built by the remote node.
For that purpose we add a new kup_selfnid field in struct
keyring_upcall_param, and a new lc_self_nid field in struct
lgss_cred.

LU-790 tests: clean up lustre version checking

Since commit 48bad5d9db9baa7bca093de5c54294adf1cf8303, the check in
sanity-scrub.sh to verify if the MDS had a new enough Lustre version
was being run before modules are loaded, if sanity-scrub.sh was run
stand-alone.  In addition to using "lctl get_param version" to get
the version, use "lctl lustre_build_version" or "lctl --version",
which will always work, even if the modules are not loaded on the
node.  This also avoids the need to load the modules just to find
that the test should not be run.

While cleaning up this code, move the lustre_version_code() earlier in
test-framework.sh, so that it is declared before calling functions,
and is co-located with the other version checking code.  Not strictly
necessary for bash scripts, but nicer when reading the code.

Fix test regressions in sanity.sh test_48[ab] since commit 13b269ab77
that incorrectly used a full path for test_mkdir() opertations instead
of using a relative filename as the test originally intended.

Also remove the obsolete check_kernel_version() code, which was only
used when we had a patched client kernel, which is no longer the case,
and remove a few overly verbose logging lines from tests.

LU-6349 ptlrpc: remove old protocol compatibility

Some old protocol compatibility workarounds are still present in
master that should have been removed when LUSTRE_MSG_MAGIC_V1 was.

In particular, the process for upgrading LUSTRE_MSG_MAGIC_V1 to
LUSTRE_MSG_MAGIC_V2 had the client to connect to the server with the
V1 protocol with op_flag=MSG_CONNECT_NEXT_VER set, and if the server
supported the V2 protocol it would reply with LUSTRE_MSG_MAGIC_V2.
This ensured that if the new client connected to an old server the
connection would be allowed.  However, even with V1 protocol support
removed, the 2.x clients are still connecting with NEXT_VER set.
In b1_8 this flag was contingent on LUSTRE_MSG_MAGIC_V1 being used,
which is how it should have been in 2.x as well.

A few other cleanups are be done at the same time:
- disallow 1.8 clients (or at least those that don't understand
  OBD_CONNECT_FULL20) so we can remove workarounds for 1.8 clients
- remove support for pre-2.1 DLM flock lock handling
- don't workaround the lack of MDS_ATTR_xTIME_SET flags in setattr
- always set MSGHDR_CKSUM_INCOMPAT18 (it can eventually be removed)

LU-6368 ldlm: Do not use cbpending for group locks

Currently, the CBPENDING flag is set on group locks when
the osc lock above them is released (osc_cancel_base).

This results in a situation where a new group lock request
on a resource does not match an existing group lock because
LDLM_FL_CBPENDING is set on the existing lock.

So two group locks are granted on the same resource, which
is not valid, since a given client can only have one group
lock on a particular resource.

Since group locks are manually released and not called back
like other LDLM locks, the CBPENDING flag doesn't make
sense.  Since they must be manually released, they also
cannot go in the LDLM LRU cache and must be fully released
immediately once they are no longer in use.

This was previously accomplished by setting CBPENDING when
the corresponding osc lock is released, but as noted above,
this prevents the group lock matching some future lock
requests.

This patch uses the fact that group locks have an l_writers
reference which they keep until they are manually released,
so we remove them when they have no more reader or writer
references, without checking cbpending.

Additionally, this patch adds several sendfile tests,

LU-6245 utils: split kernel comm between user and kernel

The kernel communication code used for HSM and changelog is
entangled. Move the user space bits into the liblustreapi. This will
also help for a possible relicensing. The kernel portion is also moved
from libcfs to obdclass.

The original libcfs_kernelcomm.h header is split into three parts:

  * lustre_kernelcomm.h, a new header for the kernel parts;
  * uapi_kernelcomm.h, a new header for the data structures shared
    between userspace and kernelspace;
  * lustreapi_internal.h receives the private liblustreapi prototypes.

The original code in kernel_user_comm.c is split into two parts:

  * obdclass/kernelcomm.c for the kernel part. filp_user_write() was
    moved there, and linux-fs.c deleted;
  * liblustreapi_kernelconn.c for the user part. The calls to CDEBUG
    have been removed, and calls to CERROR have been transformed to
    llapi_err_noerrno. The type lustre_kernelcomm has been removed and
    replace by struct lustre_kernelcomm.

Various names and filenames have been harmonized to *kernelcomm*.

The unused symbol KUC_FL_BLOCK has been removed.

LU-6300 build: Kernel string mismatch for ppc64 in RPMs

The macro in the kernel RPMs for ppc64 provided
by Redhat describing the kernel version supported,
mismatch the content of the macro of the Lustre kernel
client modules for ppc64 describing the required
kernel. This leads to unresolved dependency errors
during installation of the Lustre client modules
although the kernel versions match actually.

While Redhat uses the convention:

kernel = <major-number>-<minor-release-number>.el6

the following string is used in Lustre client RPM
for the required kernel version:

kernel = <major-number>-<minor-release-number>.el6.ppc64

The patch will remove the trailing string '.ppc64' in
macro 'krequires' defined in the lustre specfile
describing the software dependeny.

LU-6370 osc: disable to control per-OSC LRU budget

It will produce a problem where a system has lots of OSTs but
only a few of them are involved in doing read on the client side.
In that case, the per-OSC budget will cause the read ahead pages to
be dropped aggressively, which results in significantly performance
degradation.

This patch disabled per-OSC LRU budget. However, this is not a real
fix. A real fix should feed back memory pressure from LRU on the OSC
layer to the LLITE layer, so that read ahead algorithm can take that
information into consideration when it decides read ahead window size.

2. LOD thandle will distribute the thandle to all sub-thandles,

with LDLM_FL_AST_SENT set before ldlm_handle_enqueue0 sends out
reply, client side will know she needs to cancel this lock.

At the meanwhile, this lock can be added to a long granting list

However, tgt_sync may take arbitrary time which is irrelevant
to AT of lock revoke on client, server could evict client only

LU-5319 ptlrpc: Add OBD_CONNECT_MULTIMODRPCS flag

The new OBD_CONNECT_MULTIMODRPCS connection flag indicates the support
of multiple modify RPCs in parallel. It can be specified by the client
within the connection request and by the server within the connection
reply.
The new ocd_maxmodrpcs connection data specifies the maximum modify
RPCs in parallel supported by the server.

To allow the MDS to send the new ocd_maxmodrpcs field, it has been
required to modify RMF_CONNECT_DATA so that its size includes the new
field. This change leads to remove the ocd_connect_data_v1 structure.
Note that the client has been allocating an extra 16*sizeof(__u64) for
the obd_connect_data reply since 2.0 (commit fd908da9, and even in
later versions of 1.8) so there is no problem for the MDS to just send
the full reply size.

This patch fixes a bug in __req_capsule_get() since it wasn't checking
RMF_F_NO_SIZE_CHECK when receiving the message. This allows legacy
clients (with version lower that this commit) to send connection
request with ocd_connect_data structure size smaller (actually size is
ocd_connect_data_v1 structure size) than new server ocd_connect_data
structure size.

This patch also fixes a bug in the routine that displays the import's
connect data.

LU-6081 lfs: split setstripe and migrate help

The setstripe and migrate share all but one of their parameters
(--block). However the help is common to both, so the --block also
appears for the setstripe command but is not valid. So split the help
message for each command, while still sharing the same text to avoid
duplication.

reverted them.

This patch put them back, as well as adding new ones to
changelog_rec_size(), changelog_rec_varsize(), changelog_rec_rename()
and changelog_rec_jobid().

6e1365 also changed changelog_rec_name() and changelog_rec_sname() to
return a const, but that is not possible anymore.
