LU-16500 utils: 'lfs migrate' should select new OSTs

When migrating a file using "lfs migrate FILE" without any arguments
to specify a new layout, this should migrate the file to the best
OSTs available at that time based on free space, instead of keeping
the file on the same OSTs (which is almost pointless otherwise).

Reset the starting OST index for all components of the copied file
layout so that this can happen properly.  Previously, only the last
component had the OST index reset, which was only partly helpful.

Add llapi_layout_ost_index_reset() to handle this, since it seems
likely that tools using llapi_layout_from_fd() and friends to copy
an existing layout will want to do the same.  Add the corresponding
man page and reference it from llapi_layout_get_from_fd().

Update sanity test_56xe to check that the starting OST index of each
component is not the same for all components.  This check might not
catch a broken "lfs migrate" every time since even before this patch
the last component would be allocated on a random OST, but will still
fail about once every 1/$OST_COUNT runs.  Conversely, with this patch
it passes hundreds of iterations without a false positive, though a
small chance exists that it will have a false positive on occasion.

Add a "make utils" target to simplify building only user utilities.

LU-17504 build: fix array-index-out-of-bounds warning

On Linux kernel 6.5, due to commit 2d47c6956ab3
("ubsan: Tighten UBSAN_BOUNDS on GCC"), flexible
trailing arrays declared like 'lc_array_sum[1];'
will generate warnings when CONFIG_UBSAN & co. is
enabled:

UBSAN: array-index-out-of-bounds in lprocfs_status.c:1609:17
index 1 is out of range for type '__s64 [1]'

Since LPROCFS_STATS_FLAG_IRQ_SAFE flag is only used
in one place - obd_memory() counter, we can just
remove it and change obd_memory over to a regular
percpu_counter. This would both simplify the
lprocfs_counter() code, move over to using more
kernel functionality instead of libcfs, as well as
reduce overhead slightly for the memory accounting code.

LU-17624 ssk: support FIPS mode on client

In FIPS mode, only certain crypto methods are allowed. This has an
impact on the DHKE mechanism implemented for SSK, as this relies on
a prime number generated for the client key. More specifically, FIPS
mode imposes that only certain safe, well-known primes be used.

OpenSSL prior to v1.1 just imposes a requirement on the prime length.
OpenSSL v1.1 requires the use of a specific primitive when FIPS mode
is on, to fetch a well-known prime based on a prime NID.
OpenSSL v3 is capable of detecting FIPS mode is enforced, and picks up
a well-known prime instead of generating one.

Because of this, primes used for the DHKE are identical on all clients
in FIPS mode. So urge admins to use a short expiration time on SSK
keys, one day instead of one week, so that security contexts are
re-negotiated more often.

The NIST recommended primes are from see Table 26 in Appendix D of:

LU-16724 ptlrpc: simplify pool arrays

Currently, we do a fancy trick where we have a pool of
order 0, then subsequent pools start at
PPOOL_MIN_CHUNK_BITS (which is actually the minimum
compresison size).

So pool index 1 isn't a pool of order 1 (2 pages), it's a
pool of order PPOOL_MIN_CHUNK_BITS.

All this saves us is the cost of the empty pools below
PPOOL_MIN_CHUNK_BITS, but it makes the code notably harder
to read.

With this change, the order of the pool and the pool index
are the same.  This simplification will be embraced more
in subsequent patches.

LU-17700 lnet: properly calculate ping buffer size

Originally for lnet_ping() we allocated the ping buffer size by
using lnet_ping_sts_size(). The limitation to that approach is
that if the nid passed into lnet_ping_sts_size() is a smaller
NID like IPv4 the buffer could be too small. Say n_ids is 4
and 3 returned NIDs are IPv4 but one is IPv6 then it can overflow.
The solution is allocate maximum possible NID size. That can be
done with LNET_ANY_NID which fills in all the fields. For
lnet_ping_sts_size() we have to properly handle the size when
using LNET_ANY_NID. If struct lnet_nid ever increasing in the
future this code should still work.

Also cap the maximum size of the ping buffer to avoid o2iblnd
failures from using RDMA which sends data that doesn't support
large NIDs.

we can simply remove the LASSERT(ll_d_count(de) == 1)
from ll_ddelete() to avoid the above failure.

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

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.

Change-Id-Was: I1c14f6cf8cf1a19d89b5a7787aac1b67203866d3

changing.

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

with a "grow_pool" function.  (The odd plural will be
removed shortly.)

Change-Id-Was: I0accbce2c36fa97684fbee364057b8ff2f9ae12d

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.

LU-16724 ptlrpc: reduce usage of pool_index

we should just use it once.

Note the printing functions are deliberately not combined
to maximum length lines for ease of reading.

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.

LU-17053 libcfs: make a debugfs equivalent for markers

Most of the ioctl handlding that was LNet related has been moved
from libcfs to LNet. One left over are markers which allow
injection of strings into the lustre debug buffer located in
libcfs_ioctl(). This is the only functionality which exist in
libcfs yet it is only available in lnet module. We can create
an debugfs equivalent that also allows injection of strings
into the Lustre debug buffers with scripts.

LU-17409 scripts: correct ldev MGS handling

ldev was incorrectly parsing the line specifying the hosts that can
run the MGS, when of the form

gopher1 gopher2 MGS gopher1/mgs

as it assumed every target specified included a filesystem name,
like 'lustre3-MDT0000'.

This corrects that, assuming that an MGS may not be related to a
specific file system.

When such an input line is found, assume that MGS is used by any file
systems included in the ldev.conf. When user includes option '-F
<fsname>' as well as '-R MGS', include that MGS, in the targets
reported.

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

# $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-930 ptlrpc: remove spurious error messages

Stop errors being printed when a disconnect RPC times out, since
this error is ignored anyway, and adds no value to be printed.

Remove -61 = -ENODATA error from seq_server_init() since this is an
"expected" event for a new target and the error code is not useful.

LU-17609 sec: nodemap readonly_mount for remount

The readonly_mount property on nodemaps forces read-only mount from
clients. Clients trying rw remount (via mount -o remount,rw) should
also be forced to read-only.

Also improve sanity-sec test_61 to exercise client remount.
