LU-2049 grant: add support for OBD_CONNECT_GRANT_PARAM

Add support for grant overhead calculation on the client side.
To do so, clients track usage on a per-extent basis. An extent is
composed of contiguous blocks.
The OST now returns to the OSC layer several parameters to consume
grant more accurately:
- the backend filesystem block size which is the minimal grant
  allocation unit;
- the maximum extent size;
- the extent insertion cost.
Clients now pack in bulk write how much grant space was consumed for
the RPC. Dirty data accounting also adopts the same scheme.

Moreover, each backend OSD now reports its own set of parameters:
- For ldiskfs, we usually have a 4KB block size with a maximum extent
  size of 32MB (theoretical limit of 128MB) and an extent insertion
  cost of 6 x 4KB = 24KB
- For ZFS, we report a block size of 128KB, an extent size of 128
  blocks (i.e. 16MB with 128KB block size) and a block insertion cost
  of 112KB.

Besides, there is now no more generic metadata overhead reservation
done inside each OSD. Instead grant space is inflated for clients
that do not support the new grant parameters. That said, a tiny
percentage (typically 0.76%) of the free space is still reserved
inside each OSD to avoid fragmentation which might hurt performance
and impact our grant calculation (e.g. extents are broken due to
fragmentation).

This patch also fixes several other issues:

- Bulk write resent by ptlrpc after reconnection could trigger
spurious error messages related to broken dirty accounting.
The issue was that oa_dirty is discarded for resent requests
(grant flag cleared in ost_brw_write()), so we can legitimately
have grant > fed_dirty in ofd_grant_check().
This was fixed by reseting fed_dirty on reconnection and skipping
the dirty accounting check in ofd_grant_check() in the case of
ptlrpc resend.

- In obd_connect_data_seqprint(), the connection flags cannot fit
  in a 32-bit integer.

- When merging two OSC extents, an extent tax should be released
  in both the merged extent and in the grant accounting.

LU-7437 utils: continue on errors in lctl {get,set}_param

The lctl get_param, list_param, and set_param code was accidentally
changed from "handle all parameters and return any error at the end"
to "stop at the first failed parameter and return an error".

The "try all parameters" behaviour was originally implemented by
user request in 2.2.90-14-g5ad45a6 http://review.whamcloud.com/3245
but appears to have recently been broken in v2_7_63_0-45-g2d11035
by http://review.whamcloud.com/17223 moving lprocfs_param_pattern()
into the parameter handling loop rather than in the *param_display()
functions.  The new error handling for lprocfs_param_pattern() was
handled as an error, when it would previously only have been saved.
This was further aggrivated by the reorganization to cfs_get_paths()
in v2_7_66_0-10-g85cbe1a.

Restore the old error handling and add tests to verify it works.
Print error messages whenever parameter processing fails before
continuing to the next parameter, so that the user can see which
parameter(s) had the error.  Include the operation type in the
messages printed by param_display(), since this is available.

The cfs_get_paths() patch also broke "lctl list_param -D" handling
(print only directories) by returning an error when this option was
used because display_param() returned NULL for non-directories (so
they wouldn't be printed), but the error handling treated this as
ENOMEM.  Move the handling for non-directories out of display_param
to avoid this, and add a test for "lctl list_param -D".

Fix a new memory leak in display_name() if realloc() fails.  Use the
existing param_name and don't append the type suffix in this case.

LU-7578 gnilnd: Add module parameter reg_fail_timeout

During network outages on very large machines, it is possible to use
up all of GART space with connections that are in purgatory waiting
to be freed when we finally make a new connection.
This mod adds a timeout parameter so that when we fail registering
memory for fma blocks for a period of time, we can bring the node down
so it is not stuck in a state of being up but unusable.
This can only happen on service nodes as there can potentially be 10s
of thousands of connections.
A recommended setting for reg_fail_timeout would be 60 - 300 seconds.
The default setting for reg_fail_timeout is -1 (disabled).

Set fail_loc 0xf002 which fails memory registrations and see that we
BUG after the required timeout.
Test that transient registration failures within the timeout period
do not cause BUG.

LU-7584 tests: create file on single MDS in sanity test 129

In sanity test 129, it creates only one more file to check
whether the directory size exceeds the limit or not. However,
with DNE configuration, the new file might be created in a
different stripe from the previous one that hit ENOSPC.
So, directory size might not exceed the limit, which causes
the test fail.

Since the test is for checking ldiskfs dir size parameters, the
patch just fixes it to create files on single MDS so as to make
sure creating new files will increase the directory size.

LU-3538 dne: Commit-on-Sharing for DNE

This patch contains three parts:
1. Sync-on-Cancel for cross-MDT lock, which eleminates dependency
   between transactions and distributed transaction which modified
   remote object, this can guarantee the change of the distributed
   transaction will not be lost.
2. enable Commit-on-Sharing for DNE, PW/EX locks will be converted
   to COS locks, but by default they are ignored, when operation
   finds itself a distributed transaction, it will lock with
   LDLM_FL_COS_INCOMPAT flag to check against existed COS locks.
   This will eliminate dependency between distributed transaction
   and transactions which modify the same local object, and it
   guarantees distributed transaction can always be recovered.
3. striped directory creation needs to ensure its parent permanent
   on disk, to ensure this, cache child locks in mkdir.

Sync-on-Cancel for cross-MDT lock

When two operations have dependency on an object, and the first
operation has a PW/EX cross-MDT lock on this object, trigger
transaction commit on the MDT where the object resides to
eliminate dependency, in short, this patch eliminates dependency
between locks and existed PW/EX cross-MDT lock.

This patch contains following changes:
* enable Sync on Cancel for DNE by default.
* save cross-MDT lock into tgt_uncommitted_soc_locks after use,
  and it will be released upon transaction commit, note, just
  a lock refcount is taken when lock is saved, the read/write
  count is released in mdt_object_unlock().
* the saved cross-MDT lock will be discarded upon BAST,
  because the MDT where the object resides will do sync on lock
  cancel.
* use existed BLOCKING_SYNC_ON_CANCEL mechanism to commit
  transaction upon cross-MDT lock cancel.

Commit-on-Sharing for DNE

On DNE, Commit-on-Sharing is disabled by default, but MDT local
PW/EX lock will be saved as COS lock, and such lock will be
ignored in compatilibity check by default, unless it's required,
there are two situations:
1. when distributed transaction locks local object, it will
   conflict with COS locks.
2. when distributed transaction enqueues cross-MDT lock, it will
   conflict with COS locks.

This patch contains following changes:
* on DNE, local PW/EX lock is converted to COS and saved like
  before even when COS is not enabled.
* above COS locks will be ignored in lock compatibility check by
  default, so for local operations COS won't take effect. But if
  operation finds itself may modify remote MDT object, it will lock
  all local locks with COS checked.
* cross-MDT lock will always conflict with COS locks.
* if operation is reint, it will check whether it's a distributed
  operation (involved objects are remote or striped) if so, check
  against COS locks when enqueing locks.

Eliminate dependency in dir creation

Mkdir needs to take a lock on child, so that any subsequent
distributed operation using that directory would observe a conflict
and ensure that the original mkdir is committed.

Benchmark result with createmany/unlinkmany is as follows:
        mkdir rmdir open unlink mknod unlink (ops/sec)
2.6     1194 1310 1314 1185 2242 1396
master   978 1166  937 1028 1681 1202
current  930 1161  918 1018 1691 1202

* 10 createmany/unlinkmany processes running on local client
  (on MDS), 4M dirs/files created/unlinked, and the numbers are
  average of 10 processes.
* for 2.6, each process is running on a separate mountpoint.

LU-7039 llog: update llog header and size

Once update request fails due to eviction or other failures,
all of update request in the sending list should return fail,
because after the failure, the update log in the following
request will have wrong llog bitmap. So once this happens,it
will

1. invalidate all of requests in the sending list.
2. lod_sub will update the llog header from remote target.
3. Then Sending list can accept new request.

Also a few other fixes for llog corruption

1. Because the size in OSP cache is not safe, because no lock
protect it. So we will add lgh_write_offset in loghandle to
track the write offset for remote update llog, and revalidate
the offset during updating the llog header.

2. rollback the lgh_index and bitmap once add new records
fails.

Add replay-single.sh 118 to verify the case.

LU-5030 tests: remove /proc paths from tests

Remove the hard-coded /proc paths from cancel_lru_locks().  This was
only kept around because of a legacy implementation of that function
where it listed all lru_size files and then clear'd them manually.

If the filenames contained '.' then "lctl {get_param,set_param}" get

used with a wildcard parameter like "MGC*" then the '.' in the param
does not get replaced by '/' during processing and it just works.

Fix sanity-sec.sh test_24 to use "lctl get_param -R".  I couldn't see
a functional difference between the two read checks in that test,
so only left a single check.

LU-7630 mdt: keep FS capability for getattr_name

This is a follow up of LU-6528.

When "no_subtree_check" is set for NFS export, nfsd_set_fh_dentry()
doesn't set correct fsuid explicitely, but raise capability to allow
exportfs_decode_fh() to reconnect disconnected dentry into dcache.

The patch of LU-6528 fixed the issue for mdt_reint_getattr() but
missed the case for mdt_getattr_name().

LU-6528 added drop_fs_cap to old_init_ucred() to preserve
the capability but the logic was removed by LU-7199 commit
2aea469a3a, this patch reverts that.

when we have a raised capability but not a valid fsuid.

of the connection is rejected by the other side. o2iblnd will
reconnect immediately, this is going to generate a lot of

behave: reconnection is submitted by connd only if a zombie
connection is being destroyed and there is a pending
reconnection request for the corresponding peer.

Also, after a few rejections, reconnection will have a time
interval between each attempt.

at object creation. the migration process itself takes
care of nlink incrementing it atomically with dt_insert().

LU-7479 tests: fix lustre-rsync-test test_2a on SLES12

In sles12, ldd output has a wrong format for linux-vdso.so.1.
Since it is a virtual file so strip out is reasonable.

LU-6627 llite: remove extraneous export parameter

The ll_close_inode_openhandle() and ll_md_close() functions passed an
extra "obd_export *md_exp" parameter, but it turns out that all of the
callers already pass inode->i_sb->s_fs_info->lsi_llsbi->ll_md_exp in
one form or another, so it can just be extracted from "inode" directly
as needed.
