LU-12093 osc: don't check capability for every page

We check CFS_CAP_SYS_RESOURCE for every page during the io.
This is expensive on apparmor enabled systems, we can only
do that once for the entire io and use the result when
submitting the pages.

Don't init the oap_brw_flags during osc_page_init(), the flag
will be set in either osc_queue_async_io() or osc_page_submit().

LU-12098 mdd: explicitly clear changelogs on deregister

In case of MDS crash in the middle of changelog_deregister, the system

It is also possible to trigger this assert with
multi-component PFL files, where all the components are
below the stripe count limit, but together they exceed it.

PFL makes asserting based on LOV_MAX_STRIPE_COUNT
unworkable, so just remove the assert.  Further work is
planned to match up maximum allowed layout size with

LU-11566 utils: fix lctl llog_print for large configs

If "lctl llog_print" is called for a large configuration, it will
overflow the 8KB buffer limit for OBD ioctl commands.  The kernel
snprintf calls try to overflow the supplied buffer.  Avoid that.
If the configuration is large, fetch the configuration records in
chunks and print them incrementally.

Add --start and --end options to llog_print and deprecate the use of
positional parameters, since positional parameters are increasingly
complex to parse as options are added, and are harder to use.

The callback for the configuration records will allow "lctl pool_*"
commands to be processed directly on the MGS.

Move existing llog_print test_60aa, test_60ab to conf-sanity as
test_123aa and test_123ab (rename set_param -F test_123 to test_123F).

--end param, and update test_123aa to test old positional parameters.

LU-12266 mdd: fix up non-dir creation in SGID dirs

sgid directories have special semantics, making newly created files in
the directory belong to the group of the directory, and newly created
subdirectories will also become sgid. This is historically used for
group-shared directories.

But group directories writable by non-group members should not imply
that such non-group members can magically join the group, so make sure
to clear the sgid bit on non-directories for non-members (but remember
that sgid without group execute means "mandatory locking", just to
confuse things even more).

Adapt fix from inode_init_owner() to use in mdd_create_sanity_check().

LU-9193 security: return security context for metadata ops

Security layer needs to fetch security context of files/dirs
upon metadata ops like lookup, getattr, open, truncate, and
layout, for its own purpose and control checks.
Retrieving the security context consists in a getxattr operation
at the file system level. The fact that the requested metadata
operation and the getxattr are not atomic can create a window
for a dead-lock situation where, based on some access patterns,
all MDT service threads can become stuck waiting for lookup lock
to be released and thus unable to serve getxattr for security context.
Another problem is that sending an additional getxattr request for
every metadata op hurts performance.

This patch introduces a way to get atomicity by having
the MDT return security context upon granted lock reply,
sparing the client an additional getxattr request.

LU-12151 osd-ldiskfs: pass owner down rather than transfer it

Currently, for object creation, initially uid/gid set as 0,
and then osd_quota_trasfer() is called to correct space accounting
for non-root users, function call is like:

|->osd_create
  |->osd_create_type_f
     |->osd_mkreg
        |->ldiskfs_create_inode
           |->ext4_new_inode() ->owner as NULL, create 0 as uid/gid
      |->osd_attr_init
         |->osd_quota_transfer  ->which will change uid/gid again for above.

This is inefficient since osd_quota_transfer() is a more
heavy operations, we could just pass downer owner(uid,gid),
project quota will inherit from its' parents automatically
when creating inode.

Some distros ext4 still did not support passing @owner down,
that is (rhel6,sles11) we just added extra @owner arg in
ldiskfs_create_inode() to make build system happy, and we
could add similar support to older kernel if that is really needed.

Command:
 $ salloc -N 32 --ntasks-per-node=24 mpirun -np 768 mdtest -n 2000
-F -u -d <mnt>

LU-8955 sec: create new function sptlrpc_get_sepol()

Create new function sptlrpc_get_sepol() in ptlrpc/sec.c to compute
SELinux policy info, by calling new userland command l_getsepol.

The SELinux policy info syntax is the following:
<mode>:<name>:<version>:<hash>
where:
- <mode> is a digit telling if SELinux is in Permissive mode (0)
  or Enforcing mode (1)
- <name> is the name of the SELinux policy
- <version> is the version of the SELinux policy
- <hash> is the computed hash of the binary representation of the
  policy, as exported in /etc/selinux/<name>/policy/policy.<version>

Userland command l_getsepol can be called on the command line by a
security administrator to get SELinux status information to store into
'sepol' field of nodemap.

SELinux status information is reported by Lustre client only if
new 'send_sepol' ptlrpc kernel module's parameter is not zero, and
SELinux is enabled on the client.
'send_sepol' accepts various values:
- 0: do not send SELinux policy info;
- -1: send SELinux policy info for every request;
- N > 0: only send SELinux policy info every N seconds. Use max value
  2^31-1 (signed int on 32 bits) to make sure SELinux policy info is
  only checked at mount time.
Independently from 'send_sepol' value, SELinux policy info has an
associated mtime. l_getsepol checks mtime and recalculates whole
SELinux policy info (including SHA) only if mtime changed.

LU-8955 nodemap: add SELinux policy info to nodemap

Give the ability to set SELinux policy information on a nodemap,
in a new nodemap field named 'sepol'.
When set, a client pertaining to this nodemap will be allowed to
connect only if the SELinux policy information it sends matches
the one stored in the nodemap.

Expected 'sepol' string format is:
<1-digit>:<policy name>:<policy version>:<policy hash>
1-digit is 0 for SELinux Permissive mode, 1 for Enforcing mode.

SELinux policy info of nodemap is stored permanently by using
'lctl set_param -P' commands. It means MDS and OSS will be able to
retrieve SELinux policy info of nodemap after a restart (when they
read params llog).
MGS will not see SElinux policy info after restart, but this does
not prevent the feature from working.

LU-11944 llite: Lock inode on tiny write if setuid/setgid set

During a write, the setuid/setgid bits must be reset if they are
enabled and the user does not have the correct permissions. Setting
any file attributes, including setuid and setgid, requires the inode
to be locked. Writes became lockless with the introduction of
LU-1669. Locking the inode in the setuid/setgid case was added to
vvp_io_write_start() as a special case. The inode locking was not
included when support for tiny writes was added with LU-9409. This
mod adds the necessary inode lock/unlock calls to ll_do_tiny_write().

If the inode is not locked when setuid/setgid are reset, the kernel
will issue a one time warning and Lustre may hang trying to get the
inode lock in ll_setattr_raw().

LU-11825 clio: Remove pio feature

The pio feature was an interesting concept, but never
achieved real use in production, primarily because it was
actually slower than normal i/o for some common workloads,
so it could not be on by default.

It has had a trivial deadlock in it (with truncate) since
release, and this has never been reported by a customer.

The attemp to rewrite readahead to use ptasks was never
fully successful, and is being superseded by a different
implementation.

Given all this, there is no reason to keep the extra
complexity in the already complicated clio code.

LU-11591 llog: add synchronization for the last record

The initial problem was a race between llog_process_thread
and llog_osd_write_rec for a last record with lgh_last_idx.
The catalog should be wrapped for the problem. The lgh_last_idx
could be increased with a modification of llog bitmap, and a writing
record happen a bit later. When llog_process_thread processing
lgh_last_idx after modification and before a write it operates
with old record data.

The patch adds synchronization when lgh_last_idx is processed.

The patch changes llog_test 10h to check race between
llog_process_thread and llog_osd_write_rec.

1 Thread with write                  2 Thread with read
llog_osd_write_rec()                llog_process_thread()
lgh_last_idx++
lock lgh_hdr_mutex
ext2_set_bit()
dt_write_rec (write header)         ext2_test_bit()
         check lgh_last_idx was changed
         dt_read_rec()
         reread the record, and here we
         got the old value of record
unlock lgh_hdr_mutex
dt_write_rec (write the record)

LU-10913 llog: add startcat for wrapped catalog

When llog_cat_process has reached a bottom of catalog, the processing
restarts with 0. Which means a default processing. In this case a
catalog is wrapped and processing starts from a llh_cat_idx. But
records at the bottom were processed already, and were not cancelled
yet. The next message appears at log.

llog_cat_process support startcat index for processing catalog.
In this case the processing starts from startcat index. But if
catalog is wrapped startcat index is ignored.
