LU-15132 hsm: Protect against parallel HSM restore requests

Multiple parallel accesses (read/write) to the same released file
could cause multiple HSM restore requests to be sent.
On the MDT side, each restore request waits the first one to complete
before grabbing the MDS_INODELOCK_LAYOUT LCK_EX and registering the
llog record.

This could cause several MDT threads to hang for the same restore
request sent in parallel. In the worst case, all MDT threads can
hang and the MDS is not longer able to handle requests.

This patch checks if an HSM restore handle exists before taking the
lock.

The reason adding this check is because the rhel8.5 kernel has

LU-13189 osd-zfs: add project id for old objects without ZFS_PROJID

After project quota zpool upgrade, the ZFS_PROJID
flag could still be missing on some old objects.

We used to check for this and return ENXIO in
osd_declare_attr_set(), however the check is changed
by "LU-12309 osd-zfs: Support disabled project quotas".

Now if the target project id is the default
project id 0, we will pass the check in
osd_declare_attr_set() and trigger the assert in
osd_attr_set() later.

Instead of returning ENXIO, we could adjust the
attribute layout of the old objects to accommodate
project id.

Also add back the logic from "LU-14740 quota: reject
invalid project id on server side", which got removed
by "LU-14927 quota: move qsd_transfer to lquota module",
due to using GPL symbols.

LU-15713 lnet: Ensure round robin across nets

Introduce a global net sequence number and a peer sequence number.
These sequence numbers are used to ensure round robin selection of
local NIs and peer NIs across nets.

Also consolidate the sequence number accounting under
lnet_handle_send(). Previously the sequence number increment for
the final destination peer net/peer NI on a routed send was done
in lnet_handle_find_routed_path().

Some cleanup that is also in this patch:
 - Redundant check of null src_nid is removed from
   lnet_handle_find_routed_path() (LNET_NID_IS_ANY handles null arg)
 - Avoid comparing best_lpn with itself in
   lnet_handle_find_routed_path() on the first loop iteration
 - In lnet_find_best_ni_on_local_net() check whether we have
   a specified lp_disc_net_id outside of the loop to avoid doing
   that work on each loop iteration.

Added some debug statements to print information used when selecting
peer net/local net.

LU-15420 build: fixes to support building on Ubuntu 22.04 LTS

Lustre uses the glibc stdarg.h instead of the kernel's version which
causes the following build issue.

lustre/include/lu_object.h:35,
/usr/lib/gcc/x86_64-linux-gnu/11/include/stdarg.h:52: note: this is the
location of the previous definition
        #define va_copy(d,s)    __builtin_va_copy(d,s)

The solution is to use the kernels version of stdarg.h

The second build issue :
update_trans.c:1608:30: error: ‘struct task_struct’ has no member named
                        ‘state’; did you mean ‘__state’?

is due Linux commit 2f064a59a11ff9bc22e52e9678bc601404c7cb34
(sched: Change task_struct::state). The state field was
changed and the barrier macros READ_ONCE()/WRITE_ONCE()
are used to access it now which is the proper thing to do.
Since the check in update_trans.c is equivalent to testing
if the kernel thread is not running, since TASK_RUNNING == 0,
we can just change the code to use task_is_running(). The
task_is_running() was introduced in 5.13.

lctl set_param -P needs to be fixed for root squash in order
to properly propagate to clients.
On server (MDT) side, the paramaters are mdt.*.*squash*.

So if the setting on MGS side is done as

client side.
The solution is to have the settings translated into
*.*.root_squash and *.*.nosquash_nids to make both sides happy.

Also, to ensure client vs. server consistency, prevent

If the requested "start" llog records by one ioctl are just the

To fix this issue, this patch does the following changes:
- In kernel space, remember the marker cfg_flags for 10 records
  earlier than the requested "start" in function llog_print_cb(),
  so that the "start" can be output with its correct cfg_flags.
- In user space, since the pool_new/add record will be marked as
  "SKIP" if its corresponding pool_destroy/remove record is logged
  later in mgs_pool_cmd(), these "SKIP" records won't be printed
  by function jt_llog_print_iter(), so lpd_ost_num doesn't need to
  be decreased in callback function llog_search_pool_cb() as well,
  otherwise, it will cause "lctl pool_destroy" error.

LU-15593 mdt: Add option to disable use of SOM

There's currently no way to disable use of strict SOM,
which is a problem if there's ever a SOM bug.  This is
tricky to do from the client, but easy on the MDT.

The test just verifies that the size stays the same with
strict SOM disabled, because there's no easy way to check
SOM is disabled unless SOM is broken.  (Since it gives the
same value for stat.)

Note this patch requires LU-15609 to be fixed on the client
or the client will see size as 0 when SOM is disabled.

LU-15609 flr: Don't assume RDONLY implies SOM

In lov_io_slice_mirror_init, the client code assumes that
the LCM_FL_RDONLY flag in the layout implies SOM and skips
glimpse if it sees one.  The RDONLY flag means the mirrors
are in sync, which has historically implied SOM is valid.

To start with, using LCM_FL_RDONLY to imply SOM is sort of
a layering violation.  SOM is only communicated from the
MDS when it is valid, and the client already skips glimpse
in that case, so this duplicates functionality from the
higher layers.

More seriously, patch:
"LU-14526 flr: mirror split downgrade SOM"
(https://review.whamcloud.com/43168/)
Made it possible to have LCM_FL_RDONLY but not strict SOM,
so this assumption is no longer correct.

The fix is to not look at LCM_FL_RDONLY when deciding
whether to glimpse a file for size.

LU-15563 build: Include the new linux/blk-integrity.h

Linux v5.15-rc6-17-gfe45e630a103
  block: move integrity handling out of <linux/blkdev.h>

Include the new linux/blk-integrity.h

Since blk-integrity is only used in osd-ldiskfs we can migrate
the compatibility wrappers:
  blk_integrity_interval(),
  blk_integrity_name(),
  bdev_integrity_enabled(),
and
  bip_size()
to osd-ldiskfs/osd_internal.h

LU-12514 LNet: get entropy from nid when nid set.

When the 'lustre' module is loaded, it gets a list of
net devices and uses the node ids to  add entropy
to the prng.  This means that the network interfaces need
to be configured before the module is loaded, which prevents
the module from being compiled into a monolithic kernel.

So move this entropy addition to the moment when
the interface is imported to LNet and the node id is first known.

LU-15689 libcfs: libcfs_debug_mb set incorrectly on init

If libcfs_debug_mb parameter is specified to insmod (i.e. set before
module is initialized) then it does not get initialized correctly.

libcfs_param_debug_mb_set() expects cfs_trace_get_debug_mb() to return
zero if the module has not been initialized yet, but
cfs_trace_get_debug_mb() will return 1 in this case. Modify
cfs_trace_get_debug_mb() to return zero as expected. A related issue
is that in this case we need to call cfs_trace_get_debug_mb() after
cfs_tracefile_init() so that libcfs_debug_mb gets the same value it
would get if we had set it after module init.

When libcfs_debug_mb is specified to insmod, libcfs_debug_init()
divides its value by num_possible_cpus(), but this is already done in
libcfs_param_debug_mb_set().
