LU-8191 selftest: restore BUILD_BUGs

It was wrong to remove lnet_selftest_structure_assertion()
since it contained BUILD_BUGs used to ensure different LNet
Selftest versions can interoperate.

Restore the BUILD_BUGs and add a dummy user in LNet Selftest
init. This should prevent analyzers from picking this up as
an unused function.

LU-16724 ptlrpc: refactor page pools patch 1

This is a combined series that refactors the page pools
code to make it more readable.  It used to be many
separate patches but has been combined in to just three,
and this is the first.

LU-16724 ptlrpc: rename 'pool' to 'pool_idx'

'pool' here is the index of the pool, not the pool itself.
Let's give it a name that makes clear it's a number and not
the actual pool.

Also remove an error condition which is asserted on
immediately before.

LU-16724 ptlrpc: rename 'size_bits' to 'order'

The kernel uses 'order' to refer to page allocations of a
certain 'order', meaning 2^order pages.

That's what our 'size bits' is - an allocation of a certain
'order'.

Change-Id-Was: I38b184239814a0f692b644566075c798ed16f816

LU-16724 ptlrpc: rename get_buf to get_pages

The sptlrpc_enc_pool_get_buf function actually gets a fixed
number of pages, which is sort of a buffer, but is better
understood as a set of pages.

Rename the function for getting pages for a ptlrpc desc so
we can give get_buf a more appropriate name.

Change-Id-Was: I9c03b9d638e7df7f09bf5724c5a6896b7d1e7b6c

LU-16724 ptlrpc: improve usage of PAGES_POOL

improve that a bit (and start renaming a function).

Change-Id-Was: Ifed59db63d15d61d15712e6df6b8dbae56f2f5b7

LU-16724 ptlrpc: start removing 'enc' from pool

Pools are no longer encryption page pools, start renaming
them accordingly.  (The 'epp' naming in the struct has been
left for the next patch.)

Change-Id-Was: Iba3c98641e24173d95bf8bcf0df2424bbabf3ef9

LU-16724 ptlrpc: rename 'epp' to 'ppp'

Finish removing 'encryption' from page pool names except
for the module parameter, which is exposed in configuration
and so can't be changed.

'count' in the page pools code.  (And a whitespace fix.)

LU-16724 ptlrpc: correct use of plural 'pools'

pool index, but which say 'pools'.  This is very confusing,
and in fact led to me misunderstanding the code at least
once.

Clean that up.

we should just use it once.

Note the printing functions are deliberately not combined

LU-17680 ldlm: fix ldlm_res_hop_hash() argument

Change ldlm_res_hop_hash() to use "bits" instead of "mask" as the

down to very few buckets (e.g. "hash & 8" or "hash & 11") instead of
the full bit range (e.g. "hash & ((1 << 8) - 1)".

This is causing significant slowdowns for file creation performance,
in particular sanity test_123ac was running 2x slower when creating
a large number of files because of the bad hashing.

In the call ->coo_attr_get in LOV layer, the client should also

Otherwise, the client may get 0 block count. It is very easy to
reproduce this problem via the following commands for a archived
file:
# $LFS hsm_restore $file
# $LFS hsm_release $file
# $LFS hsm_release $file
After release a file twice, the reported block count via stat()

LU-17612 sec: return keyring errors to userspace

In current code, Linux keyring errors, when using GSS Kerberos,
are all masked under a generic ECONNREFUSED error. That makes
it hard to understand the root cause of the problem
for the I/O caller.

Update the code to propagate errors from request_key() up to
the application.

struct ptlrpc_cli_ctx * gss_sec_lookup_ctx_kr(...) is modified
to now returns a NULL pointer or -errval. This is tested by callers
and propagated. NULL values are still converted to ECONNREFUSED.

LU-17605 obdclass: do not wait forever acquiring entry

The process of refreshing an entry via refresh_entry() goes through
an upcall/downcall. If the upcall succeeds, we enter a wait queue.
If after that the downcall is never called, we hit the expiry timeout,
and we get removed from the wait queue.
But if the entry is not new, the expiry time will be
MAX_SCHEDULE_TIMEOUT == LONG_MAX, which means an infinite wait.
So avoid waiting forever if an entry could not be refreshed, and call
wake_up_all() if the wait for the ACQUIRING state failed.

LU-17510 obdclass: fix wake up when queuing close request.

The waitqueue for requests that need to be sent but that haven't been
allocated a slot is kept ordered by request arrival for fairness.  So
new requests are added to the end.

For requests other than 'close' there is a limit to the number of
active requests (slots) and requests are assigned to slot on a
first-come-first-served basis, so they are simply removed from the
head of the list.

For 'close' requests it is important that these not block indefinitely
behind other other requests so there is one slot that can only be used
by a close request - and only if no other slots are used by a close
request.  These requests do not follow a strict FIFO order.

When a non-"close" request completes we wake the first request on the
list.  There is no point searching all the way down the list for a
close request that could also be woken.  We only do that when a
"close" request completes.  This optimises the common case.

However: when a request is first queued we add it to the end of the
queue and then wake up the first deserving request if there is one.
When there are free slots, this is expected to wake the request just
queued.  When there are no free slots, nothing is woken.

When a "close" request is queued and added to the end of the queue
after other non-close requests, we need to potentially search to the
end of the queue for a close request to wake, just as we do when a
close request completes.  Unfortunately we don't.  This can result in
a close request blocking indefinitely.

So: change the wakeup in obd_get_mod_rpc_slot() to match the wakeup in
obd_put_mod_rpc_slot().  This ensure consistent handling and in
particular will handle a close request immediately if there are no
other close requests in flight.

Clarify comment in claim_mod_rpc_function() to make and perform minor
code cleanup there.

Two different tests are performed, with a ramp of locks to keep to
allow seeing any scalability issues:
1/ create lots of non-overlapping extents in
   random order, keeping up to 8000 at a time.
2/ create both random tiny extents and whole-file
   extents, alternating.  Keep up to 1,000,000.
   These are PR and so don't conflict.

Each test runs for at most 5 minutes
(30 loops of 10 seconds each = 300 seconds).

LU-12019 build: remove global depmod.d conf from debs

Lustre should not be creating a global depmod.d configuration
file that affects the load order of all modules installed
on the system.

Yet, Lustre has a depmod.d configuration file that attempts
to mirror the default configuration (the man page is
identical for Debian):

https://manpages.ubuntu.com/manpages/xenial/en/man5/depmod.d.5.html

"By default, depmod will give a higher priority to a
  directory with the name updates using this built-in
  search string: "updates built-in" but more complex
  arrangements are possible and are used in several
  popular distributions."

However, when we switched from:

search updates built-in

to:

search updates/kernel built-in

Ubuntu depmod was forced to prefer build-in modules, since
the modules are not in `updates/kernel` as in Debian. If a
user has third party modules installed on their system, this
could make Ubuntu load the wrong module by default.

This patch removes the lustre.conf depmod.d file. By
leaving these load-order decisions to the distribution, this
patch addresses the regression on Ubuntu.

LU-17248 kernel: wait for pages under writeback for bdev

Since RHEL 8.6 wait_for_stable_page() is controlled by
a new flag SB_I_STABLE_WRITES on the super block.

However the new flag is not set on the bdev pseudo sb,
which mean when doing write directly to the block device
we are not waiting on page writeback, this could trigger
false block integrity errors, as page could be modified
again when under writeback, the integrity checksum does
not match the new data any more.

Upstream has a pending patch
https://lore.kernel.org/linux-mm/20231025141020.192413-1-hch@lst.de/
which works for RHEL 9 kernels.

For RHEL 8 kernels the changes for bdev made it difficult
to backport, a different patch is used to check and wait
for bdev stable_pages.

LU-16935 llite: avoid hopeless i/o repeats

On SLES12SP5 kernels (4.12.14_122.147, 4.12.14-122.162) a race between
ll_filemap_fault and ll_imp_inval may lead to the livelock:

  - ll_filemap_fault loops endlessly as filemap_fault()->readpage()
    returns VM_FAULT_SIGBUS (it is unable to send read rpc as import
    is invalid) and as ll_page_inv_lock gets incremented within
    cl_page_discard()->..->vvp_page_delete() called after readpage
    failure.

  - ll_imp_inval stucks in
    obd_import_event(IMP_EVENT_INVALIDATE)->..->osc_object_invalidate
    (before recovery) waiting for completion of i/o ll_filemap_fault
    can not complete.

@ll_page_inv_lock is used to check the page being read by kernel
after it has been deleted from Lustre, which avoids potential
stale data reads. This seqlock allows us to see that a page was
potentially deleted, catch it in this case and repeat the I/O in
ll_filemap_fault() or vvp_io_read_start().

To avoid endless I/O repeat wrongly, in this patch we only increse
@ll_page_inv_lock for the page in PageUptodate state when delete
the page in vvp_page_delete(). The page that not in PageUptodate
state is usually deleted due to the error that does not require
retry.
By this way, ll_filemap_fault() and vvp_io_read_start() will not loop
endless for those errors that does not need to repeat I/O as the
seqlock @ll_page_inv_lock does not have any change.

Test to illustrate the issus is added.

sanity.sh tests are to test i/o error handling.

cl_io_loop(): avoid restart if ci_tried_all_mirrors flag is set.
