LU-11999 dne: performance improvement for file creation

This is to remove an obsoleted code where it causes drastic
performance degradation. This code is written before PERM lock
is introduced, and it requests UPDATE lock at path walk for
remote directory, which will be cancelled at later file creation.

Tests result before and after this patch is applied:

Test case:
rm -rf /mnt/lustre_purple/testdir
lfs mkdir -i 0 /mnt/lustre_purple/testdir
lfs mkdir -i 2 /mnt/lustre_purple/testdir/dir2
./lustre-release/lustre/tests/createmany -o \
/mnt/lustre_purple/testdir/dir2/f 10000

Before the patch is applied:
total: 10000 open/close in 12.82 seconds: 780.22 ops/second

After the patch is applied:
total: 10000 open/close in 4.89 seconds: 2044.75 ops/second

    osp_disconnect() ASSERTION( imp != ((void *)0) ) failed:
    osp_disconnect() LBUG
    CPU: 1 PID: 10059 Comm: llog_process_th

Problem is obd_disconnect() will cleanup @imp and set NULL.

    ->class_manual_cleanup
       ->class_process_config
          ->class_cleanup
             ->obd_precleanup
                ->osp_device_fini
                   ->client_obd_cleanup

While ldo_process_config() will try to access @imp again:
 ->ldo_process_config
    ->osp_shutdown
       ->osp_disconnect
          ->LASSERT(imp != NULL)

Another problem is if we failed before obd_connect().
we will hang on with mount:
 ->ldo_process_config
    ->osp_shutdown

             ->rc = l_wait_event(imp->imp_recovery_waitq,
                                 !ptlrpc_import_in_recovery(imp), &lwi);

Since connect is not called, imp state will stay LUSTRE_IMP_NEW.
Fix this by check whether we are in recovery properly, only consider

LU-11894 lnet: check for asymmetrical route messages

Asymmetrical routes can be an issue when debugging network,
and allowing them also opens the door to attacks where hostile
clients inject data to the servers.

In order to prevent asymmetrical routes, add a new lnet kernel
module option named 'lnet_drop_asym_route'. When set to non-zero,
lnet_parse() will check if the message received from a remote peer
is coming through a router that would normally be used by this node
to reach the remote peer. If it is not the case, then it means we
are dealing with an asymmetrical route message, and the message will
be dropped.

The check for asymmetrical route can also be switched on/off with
the command 'lnetctl set drop_asym_route 0|1'. And this parameter is
exported/imported in Yaml.

LU-11579 llite: remove cl_file_inode_init() LASSERT

If there is some corruption or other reason that the file layout
cannot be used, the first call to cl_file_inode_init() will fail.
If it is called a second time on the same file then it will hit
an LASSERT() since I_NEW is no longer set on the inode.

It would be good to handle the error in lov_init_raid0() better,
but we still want to avoid this LASSERT() if there is an error.

Convert the LASSERT() in cl_file_inode_init() into a CERROR() and
error return.  This is being triggered due to corruption on the
server, but that shouldn't cause the client to assert.

LU-11625 ofd: handle upgraded filter_fid properly

Since there have been several iterations of struct filter_fid stored
on disk, the current code wasn't checking for all of the possible
cases when trying to decide what action to take when accessing and
upgrading the xattr for new capabilities.

Properly check for the various different struct filter_fid sizes and
handle them appropriately.  Add a more verbose description of the
various cases so that this is more clear to others in the future.

Add decoding of filter_fid fields added for FLR in 2.11.

We should already be testing for upgrading the filter_fid xattr
from different OST versions in conf-sanity test_32d.

LU-11809 llite: don't use %p to generate cfg_instance

In kernel 4.15 and later, using "%p" in a string format to
print a kernel pointer will result in the pointer being
hashed with a random value, and the high bytes will be masked
on 64-bit CPUs to prevent leaking kernel address-space info
to userspace to defeat ASLR.  In early boot, the "%p" pointer
may resolve to "        (ptrval)", if there is not enough
entropy in the system to generate a random hash value.

The superblock pointer is used on the client to uniquely
identify all of the OBD devices connected to it, and to
find the configuration llog that was used to mount the
filesystem, so that it can also be used at unmount time.
The sb pointer is also used in the OBD device names, and
the "        (ptrval)" expansion breaks /sys filenames,
and also breaks the uniqueness of the config instance.

On the server, there is also a pointer value used for the
FLDB SEQ servers of the OSTs.

For the short term, bypass the "%p" hashing, so that mount
continues to work properly, and this can be resolved in a
later patch to change ll_get_cfg_instance() to provide a
unique value that is not directly a kernel pointer.

In llapi_getname() don't depend on the cfg_instance being
exactly 16 characters long, if this changes in the future.

LU-11783 build: remove lustre_user.h deprecation warning

The "lustre/lustre_user.h" header has been in use for many years.
The patch https://review.whamcloud.com/25246 "LU-6401 uapi: migrate
remaining uapi headers to uapi directory" moved the header to
"linux/lustre/lustre_user.h" and left a stub "lustre/lustre_user.h"
behind that generates a compiler warning that this header is
deprecated.

However, no window was given between the introduction of the new
header and the deprecation of the old header, which makes it harder
for applications to smoothly transition to the new header location.
Also, installing Lustre headers into the "linux/" directory before
Lustre is actually part of the kernel may potentially cause problems.

LU-11770 osd-ldiskfs: preserve bio_integrity API

Preserve the existing kernel API for bio_integrity when the T10-PI
patches are applied, so that any other code that may be using this
interface do not break.

In particular, keep the EXPORT_SYMBOL(bio_integrity_alloc) and
EXPORT_SYMBOL(bio_integrity_prep) in place to avoid module breakage.

In struct bio_integrity_payload put the *bip_generate_fn and
*bip_verify_fn pointers after *bip_vec, since bip_vec is the last
field directly accessed by callers.

In struct blk_integrity_exchg the bi_idx field only needs to be an
unsigned short since the bio->bi_idx and bio->bi_vcnt values used
with it are also unsigned short.  This saves 8 bytes of padding in
the struct and puts the added bi_bio field at the end to preserve
the structure field alignment for external callers.

LU-9793 ptlrpc: Do not map unrecognized ELDLM errnos to EIO

The lustre_errno_hton and lustre_errno_ntoh functions map between
host and network error numbers before they are sent over the network.
If an errno is unrecognized then it is mapped to EIO.

However an optimization for x86 and i386 architectures replaced the
functions with macros that simply return the original errno. The
result is that x86 and i386 return the original values for ELDLM
errnos and all other architectures return EIO. This difference is
known to break glimpse lock callback handling which depends on clients
responding with ELDLM_NO_LOCK_DATA. The difference in errnos may
result in other as yet unidentified bugs.

The fix defines mappings for the ELDLM errors that leaves the values
unchanged. Error numbers not found in the mapping tables are still
mapped to EIO.
