LU-11130 osd-ldiskfs: create non-empty local agent symlinks

e2fsck doesn't like zero-sized symlink inodes created by

It would be better to just migrate the whole symlink instead

there is not a hard link to the symlink (which POSIX allows,

keep the remote symlinks to ensure on-disk consistency with

LU-10406 mdt: invalidate cache upon LDLM lock

given new components (like LFSCK) can access storage w/o LDLM
locking, it's possible to find cache stale. so MDT should
invalidate local cache explicitly once LDLM lock is granted.

also, OSP should invdalite any state requested before invalidation
request as LDLM lock and request can be handled in different
order on the target and source MDTs. for example, get_attr was
sent first, the target MDT serviced it first, but the reply got
delayed for a reason. in the meantime LDLM lock was requested,
granted and received by the source MDT before reply for get_attr.
IOW, we get a state with old (potentially stale) state and LDLM
lock granted.

LU-10472 osd-ldiskfs: T10PI between RPC and BIO

When OST recieves bulk write RPC, the T10PI guard tag will be
generated during the process of calculating RPC checksum with
T10PI type. Guard tags of each sector will be copied to the
BIO integrity payload to avoid recalculating of guard tags.

When OST reads data from disk, the T10PI guard tags will be
copied from BIO integrity payload. These guard tags will be
reused for calculation the RPC checksum with T10PI type, thus
no recalcuating of guard tags is needed either.

However, if the data that the client is reading is cached
in memory, the guard tags need to be calculated based on the
cached data, since there is no place to plug the guard tags
to the page cache on OSS.

Some modification to Linux kernel is needed:

1) We can pass “struct bio *” and  to the integrity
generate/verify methods, and struct blk_integrity_exchg
has bi_idx which is the current bio_vec index.

2) bio_integrity_prep accepts optional pointers to integrity
generation/verification methods. The optional methods take
priority over the ones registered by the device.

These two modification enable Lustre (and other file systems) to
integrate with BIO for integrity verification/generation. Any private
data need during data integrity generation/verification process can
be attached to bio->bi_private. Instead of calculating guard tags,
Lustre generation method will copy the guard tags from existing
buffer. And instead of (or besides of) data integrity verification,
Lustre verification method will copy the guard tags to internal
buffer for further usage.

Besides of these changes, two Linux kernel patches are applied:

1) The first problem is that bio_integrity_verify() doesn't verify
the data integrity at all. In that function, after reading the data,
bio->bi_idx will be equal to bio->bi_vcnt because of bio_advance(),
so bio_for_each_segment_all() should be used, not
bio_for_each_segment(). And also, bio_advance() should not change
the integrity data bio_integrity_advance() unless the BIO is being
trimmed.
Linux-commit: 63573e359d052e506d305c263576499f06355985

2) The second patch fixes a problem of the sd_dif_complete(). When
sector offset is larger then 2^32, the mapping from physical
reference tag to the virtual values expected by block layer will be
wrong.

LU-10695 tests: fix sanity-lfsck test_23c

sanity-lfsck test_23c fails intermittently with "(8) unexpected size"
while introducing the required corruption to the filesystem to run
the test.

It appears that in these cases, LFSCK has actually fixed the file
before it can be "further corrupted" as part of the test.  In
this case, the test failure is actually a sign that LFSCK is working
correctly, so it should not be considered a test failure.

Add a check that the file was repaired correctly (contains original
data) and consider the test a pass.

LU-11423 osc: Do not walk full extent list

It is only possible to merge with the extent immediately
before or immediately after the one we are trying to add,
so do not continue to walk the extent list after passing

This has a significant impact when writing large sparse

extents are too distant to be merged with their neighbors.

Rename "lfs mirror dump" command to "lfs mirror read".

Add "lfs mirror write" command to write a mirror's content of a

Usage:

lfs mirror write {--mirror-id|-N <mirror_id>}
[--inputfile|-i <input_file>] <mirrored_file>

Options:

--mirror-id|-N <mirror_id>
  This  option  indicates  the  content of which mirror specified by
  mirror_id needs to be written. The mirror_id is the numerical unique
  identifier for a mirror.

--inputfile|-i <input_file>
  The path name of the input file, if not specified, the standard
  input stream will be used. The input stream or input_file cannot
  be the same mirrored file as the mirrored_file.

This command will issue a RESYNC lease write lock to notify MDS to
prepare destination mirror for the write (instantiate components of
the mirror), then client copy data from a file or STDIN to the
specified mirror of the mirrored file. After the data copy, a
RESYNC_DONE lease unlock is issued to MDS to update the layout

LU-11101 quota: fix setattr project check

Similar patch motivated by upstream patch:
ext4: fix setattr project check in fssetxattr ioctl

Currently, project quota could be changed by fssetxattr
ioctl, and existed permission check inode_owner_or_capable()
is obviously not enough, just think that common users could
change project id of file, that could make users to
break project quota easily.

This patch try to follow same regular of xfs project
quota:

"Project Quota ID state is only allowed to change from
within the init namespace. Enforce that restriction only
if we are trying to change the quota ID state.
Everything else is allowed in user namespaces."

LU-10030 idl: use proper ATTR/MDS_ATTR/MDS_OPEN flags

Add proper MDS_ATTR_* and MDS_OPEN_* flags for different flags
namespaces.  The MDS_OPEN_OWNEROVERRIDE was being mapped into
the MDS_ATTR_* flags in some cases.  This did not conflict yet, but
add separate ATTR_OVERRIDE and MDS_ATTR_OVERRIDE flags for this use
so they don't conflict in the future.

Remove the MDS_OPEN_CROSS flag, since this was only used internally
as a hack to pass open flags to mdd_permission(), but was truncating
the u64 open flags to a 32-bit int in the process.  Do the convert
to MAY_* flags at the MDT layer instead of inside mdd_permission()
by moving the accmode() flag conversion into lustre_mds.h code.

The ATTR_OPEN flag has existed since kernel 2.6.27, so we can always
use that directly instead of the ATTR_FROM_OPEN flag we #defined.
The ATTR_RAW flag is no longer used at all and can be removed.

Rename various "flags" uses in the code to "open_flags" so that it
is more clear which flags values are being used.  This exposed a few
places in the code where we were using an int to pass these flags, but
some of the MDS_OPEN_* flags are using 64-bit values already.

LU-8066 obd: use correct names for conn_uuid

The LUSTRE_R[OW]_ATTR() macros assume that the name of the sysfs
file to create matches the beginning of the function names. In
the case of LUSTRE_RO_ATTR(conn_uuid) this maps to the function
conn_uuid_show() and generated sysfs files "conn_uuid". While it
makes sense to standardize this interface we need to keep the
old xxx_conn_uuid. We can create these xxx_conn_uuid sysfs files
by using the base sysfs attr macro LUSTRE_ATTR().

LU-10337 mdt: Allow open of open orphans

Standard open by handle behavior allows opening of open
unlinked files files.  This currently only works in Lustre
if the file is already open on the same node, which is
insufficient.

When an open file is unlinked, we make it an orphan.
These files can be recognized by checking their open count
(mod_count).  It's enough to just make opening these files
possible, because the client cannot look them up to do an
open except when using a file handle.

In ldlm_handle_cp_callback(), we call lock_res_and_lock and then

However this gives another thread an opportunity to grab the lock
