LU-13969 - Updates to lustre-release yaml.sh

Updated output of release() function to standarize node.yml file
os_distribution parameter. Changes as follows:

RHEL   - use redhat-release first and os-release as backup as the latter may
         not include the full version (major/minor)
CENTOS - use centos-release first and os-release as backup, same as RHEL
SUSE   - use os-release instead of suse-release as the latter is deprecated
UBUNTU - use os-release

Removed parsing system-release and *-release as neither
option correctly outputs desired info

Removed "lustre_" references in node.yml file attributes, the default in Maloo
is to look for non-lustre prefixes first

LU-6142 lustre: don't take spinlock to read a 'long'.

Reading a 'long' (or unsigned long) is always an atomic operation.
There is never a need to take a spinlock to just read a single 'long'.

There are several procfs/debugfs/sysfs handlers which needlessly take
a spinlock for this purpose.

This patch:
- removes the taking of the spinlock
- changes the printf to scnprintf() as appropriate
- directly returns the value returned by scnprintf rather than
storing it in a variable
- accesses the 'long' as an arg to the scnprintf(), rather than
introducing a variabe to hold it.

LU-11518 ldlm: pool fixes

At the time the client side recalc period was increased up to 10secs
the grant & cancel rates started showing the speed not in seconds but
in tens of seconds.

At the pool initialization time, the server side recalc job should not
be delayed on client's recalc period.

It may happen an NS time is significant and comparable (or even more)
than the recalc period of the next NS (all the following NS's) in the
list. If the time has been already spent on the next NS, it does not
mean we want to double the delay for the original NS and recalc after
next N secs.

Make lock volume factor more fine grained (default is 100 now vs the
original 1): it is likely to cancel locks on clients twice faster than
server requested is too fast.

Protect missed pl_server_lock_volume update by the pool lock.

Replace ktime_get_real_seconds with ktime_get_seconds for the recal
interval.

LU-11518 ldlm: control lru_size for extent lock

We register ELC for extent locks to be canceled at enqueue time,
but it can't make positive effect to locks that have dirty pages
under it. To keep the semantics of lru_size, the client should
check how many unused locks are cached after adding a lock into
lru list. If it has already exceeded the hard limit
(ns_max_unused), the client will initiate async lock cancellation
process in batch mode (ns->ns_cancel_batch).

To do it, re-use the new batching LRU cancel functionality.

Wherever unlimited LRU cancel is called (not ELC), try to cancel in
batched mode.

And a new field named new sysfs attribute named *lru_cancel_batch*
is introduced into ldlm namespace to control the batch count.

LU-12275 sec: verify dir is empty when setting enc policy

When setting an encryption policy on a directory that we want to
be encrypted, make sure it is empty.
Otherwise return -ENOTEMPTY from server to client doing the ioctl.

Also add test to exercise the ioctl interface to get/set encryption
policies on directories, thanks to the fscrypt userspace tool.
And test the ability to lock an encrypted directory.

LU-10360 mgc: Use IR for client->MDS/OST connections

When a target registers with the MGS, the MGS sends an IR log
to the client to speed up recovery.

The IR log contains the updated NID information on the target
which just registered.

This patch allows clients to update their imports with the latest
NIDs for the targets reported in the IR log. It also allows clients
to create new connections for targets which were not added via
the config log.

For example if a target reboots and comes up with a new NID, then
the client can continue using it.

This functionality is disabled by default and can be enabled by
setting a new file system specific module parameter, dynamic_nids.

lctl set_param mgc.*.dynamic_nids=1

This parameters will need to be set on the clients and the MGS

LU-13909 tests: get lustre_inode_cache count from sysfs

If slab cache merging is enabled (which is the default for newer
kernels), then there may not be a dedicated 'lustre_inode_cache'
entry in /proc/slabinfo (it may be aliased with 'signal_cache' and
'ptlrpc_cache' and/or other slabs of the same size).  This may result
in num_inodes() returning nothing to the caller, causing sanity
test_76() to not actually check anything useful.

Instead of looking for the number of cached inodes in /proc/slabinfo,
get this count from /sys/kernel/slab/lustre_inode_cache/objects if
available.  While it may not hold the actual number of cached inodes
due to slab sharing, sanity test_76 only cares about the relative
increase in cached inodes before and after running the test.

Due to slab sharing, the margin for error in counting cached objects
in the "lustre_inode_cache" slab can be fairly large (it may also be
shared with 'ptlrpc_cache' and increase significantly when sending
many RPCs).  The main goal of test_76 is to ensure there are not
persistently more objects cached in this slab compared to before
the create/unlink loop was run.

LU-12275 sec: encryption with different client PAGE_SIZE

In order to properly handle encryption/decryption on clients that have
a PAGE_SIZE != LUSTRE_ENCRYPTION_UNIT_SIZE (typically aarch64/ppc64),
a few adjustements are necessary:
- when encrypting, do not proceed with PAGE_SIZE as encryption length.
  Instead, round up to a multiple of LUSTRE_ENCRYPTION_UNIT_SIZE.
  On aarch64/ppc64, it avoids encrypting way beyond
  LUSTRE_ENCRYPTION_UNIT_SIZE when the page is not full.
- when decrypting, do not proceed with PAGE_SIZE as decryption length.
  Instead, do LUSTRE_ENCRYPTION_UNIT_SIZE length at a time. It enables
  proper detection of 'all 0s' sent by servers for content beyond file
  size.

Regarding tests, add sanity-sec test_53 to exercise encryption from
clients with different PAGE_SIZE.
The trick to achieve this with AT is to expect the client to have 64KB
PAGE_SIZE, and the servers to have 4KB PAGE_SIZE, and then mount a
client from the MDS node.
This also means code running on server side needs to have client
encryption support enabled, so CentOS/RHEL 8 at least.

originator of a message to set the final destination NID. On a
multi-hop route, intermediate routers execute the same code path as
the message originator (i.e. the remote send cases). This causes
them to overwrite the destination NID when forwarding the message.

Check the msg_routing flag to determine whether we should set the
final destination NID (i.e. LNet peer NI).

A somewhat related issue is that because intermediate routers are not
selecting a destination lpni, they need to pick the next-hop lpni
based on the destination NID's remote net.

LU-13909 llite: prune invalid dentries

When file LOOKUP lock is canceled on client, mark its dentries
invalid, and also prune them to avoid OOM, to achieve this,
ll_invalidate_aliases() is renamed to ll_prune_aliases(), the latter
calls d_prune_aliases() to prune unused invalid dentries.

The same for negative dentries when parent UPDATE lock is canceled,
rename ll_invalidate_negative_children() to
ll_prune_negative_children().

Since now unused invalid dentries will always be pruned, it's not
necessary to call __d_drop() in d_lustre_invalidate().

It's redundant to take i_lock before d_lustre_invalidate() in
ll_inode_revalidate() because d_lustre_invalidate() takes d_lock,
remove it.

LU-13151 mdt: add parent FID to Changelog recordss

Use the link EA to add the parent FID to ChangeLog records, including
MTIME, TRUNC, and SATTR.

Some tools that maintain copies of filesystem metadata in an external
database monitor changelogs for changes to the filesystem, in order to
determine files that need to be rescanned. This can result in a large
number of small updates to the external database that can reduce the
tool's ingest performance. It might be beneficial to instead track and
scan complete directories that contain modified files and update the
external database using bulk operations. Adding the parent FID to
MTIME changelogs allows to more efficiently determine the parent
directories for some types of file data modifications, by issuing
OBD_IOC_FID2PATH once for each parent FID, instead of once for each
file FID.

LU-12780 osd: use native kthreads for scrub.

The 'scrub' thread has nothing to do with ptlrpc, so
using ptlrpc_thread is strange - and not necessary.  This patch
switches to native kthread interfaces.

A particular advantage of the switch is seen in the convertion of
thread_is_running().
This is uses in two completely different ways.
1/ The thread itself needs to know if it has been asked to stop.
  It currently uss thread_is_running().  After the patch it
  uses kthread_should_stop().

2/ Other code needs to know if the thread is still active or not.  It
  previously used thread_is_running(), so it looked just like the
  first case.  Now it checks a new flag ->os_running, which is
  set precisely when SVC_RUNNING was set, and cleared when any other
  status was set.

As the thread can stop itself (e.g if osd_scrub_prep fails) or can be
asked to stop (scrub_stop()), we need to avoid confusion between the
two.  This is achieved by calling 'xchg(&scrub->os_task,NULL)'.
If the thread finds that to be non-NULL, it has stopped itself
and can just exit.  If scrub_stop() finds it to be non-NULL,
it calls kthread_should_stop() to stop the thread.

Instead of using the waitqueue in the 'struct ptlrpc_thread', we use
wake_up_var() and wait_var_event() on the 'scrub' pointer.  This is
used both to tell the thread there is work to do, and for callers to
wait for the task to make progress, or to exit.

LU-13846 llite: move iov iter forward by ourself

Newer kernel will reward iov iter back to original

This break assumptions from Lustre and caused problem
when Lustre need split one IO to several io loop, considering
4M block IO for 1 MiB stripe file, it will submit first 1MiB IO
4 times and caused data corruptions finally.

Since generic kernel varies from different kernel versions,
we'd better fix this problem by move iov iter forward by
Lustre itself.

Added a new test cases aiocp.c is copied from xfstests,
with codes style cleanups to make checkpatch.pl happy.

LU-10428 lnet: call event handlers without res_lock

Currently event handlers are called with the lnet_res_lock()
(a spinlock) held.  This is a problem if the handler wants
to take a mutex, allocate memory, or sleep for some other
reason.

The lock is needed because handlers for a given md need to
be serialized.  At the very least, the final event which
reports that the md is "unlinked" needs to be called last,
after any other events have been handled.

Instead of using a spinlock to ensure this ordering, we can
use a flag bit in the md.

- Before considering whether to send an event we wait for the flag bit
  to be cleared.  This ensures serialization.
- Also wait for the flag to be cleared before final freeing of the md.
- If this is not an unlink event and we need to call the handler, we
  set the flag bit before dropping lnet_res_lock().  This
  ensures the not further events will happen, and that the md
  won't be freed - so we can still clear the flag.
- use wait_var_event to wait for the flag it to be cleared,
  and wake_up_var() to signal a wakeup.  After wait_var_event()
  returns, we need to take the spinlock and check again.

LU-13127 ptlrpc: prefer crc32_le() over CryptoAPI

Prefer to call the crc32_le() library function directly if available,
instead of cfs_crypto_hash(CFS_HASH_ALG_CRC32). It is about 10x faster
for the 156-byte struct ptlrpc_body being checked in this function.
A test of small buffers in that compares the two implementations, run
on a 2.9GHz Core i7-7820 shows the difference is significant here:

  buffer size   156 bytes   1536 bytes   4096 bytes     1 MiB
  -----------+------------+------------+-----------+-----------
  cfs_crypto |  182 MiB/s | 1794 MiB/s | 4163 MB/s | 9631 MiB/s
  crc32_le   | 1947 MiB/s | 1871 MiB/s | 1867 MB/s | 1823 MiB/s

This corresponds to 10x faster or 1/10 as many cycles for ptlrpc_body.
The CryptoAPI speed crosses over around 1536 bytes, which is still 10x
larger than the ptlrpc_body size, so it is unlikely to be faster here.

LU-13818 build: use libsnmp-dev instead of libsnmp30

Installing libsnmp-dev will pull in the correct libsnmpXX.
By depending on the libsnmp-dev we can install on
ubuntu 20.04 which is libsnmp35

LU-9325 fld: replace simple_strto* with kstr* functions

The fldb debugfs files use simple_strto* to parse input from the
user. simple_strto* is considered obsolete so replace it with
the equivalent kstrto* functions.

LU-13791 sec: enable FS capabilities

FS capabilities are not effective because they are dropped for
non-root users for historical reason: they are used to be enforced
before operations, but now they are checked in MDD layer only (see
mdd_fix_attr()).

Add sanity-sec 51.

LU-9859 libcfs: don't save journal_info in dumplog thread.

As this thread is started by kthread, it must have
a clean environment and cannot possibly be in a
filesystem transaction. So current->journal_info
must be NULL, and preserving it serves no purpose.

Also change libcfs_debug_dumplog_internal() to 'static'
to make it clear that it shouldn't be called from
anywhere but this thread.

LU-9859 libcfs: rename CFS_TCD_TYPE_MAX to CFS_TCD_TYPE_CNT

The possible TCD types are 0, 1, 2.
So the MAX is 2.
The count of the number of types is 3.

CFS_TCD_TYPE_MAX is 3 - obviously wrong.

So rename it to CFS_TCD_TYPE_CNT.

Also there are 2 places where "3" is used rather
than the macro - fix them.
