Merge latest new OpenSFS work to native Linux client. Biggest
change is the native support of the Lustre utilites with the
Linux client!!!! I do see new test failures due to the debugfs
root only issues which will be addressed later.

If a peer is created by Lustre make sure to lock that peer's
primary NID. This peer can be discovered in the background.
There is no need to block until discovery is complete, as Lustre
can continue on with the primary NID it provided.
Discovery will populate the peer with other interfaces the peer has
but will not change the peer's primary NID. It can also delete
peer's NIDs which Lustre told it about (not the Primary NID).

From: Hongchao Zhang <hongchao@whamcloud.com>
In patch https://review.whamcloud.com/30146 "LU-5152 quota: enforce
block quota for chgrp", problems were introduced due to synchronous
requests from the MDS to the OSS to change the quota assignment of
files during chgrp operations. However, in some cases, the OSTs are
themselves out of grant and may send a quota request to the MDS,
which may result in a deadlock. Another issue is the slow performance
caused by the synchronous operation between MDT and OSTs.
This patch drops the synchronous RPC requirement of the original
patch #30146 to avoid this problem.
Previously, problems in quota tracking related to chgrp were introduced
due to synchronous RPCs from the MDS to the OSS when changing the group
ownership of objects for quota tracking since

From: Mr NeilBrown <neilb@suse.de>
LNet nids are currently limited to 4-bytes for addresses.
This excludes the use of IPv6.
In order to support IPv6, introduce 'struct lnet_nid' which can hold
up to 128bit address and is extensible, and deprecate 'lnet_nid_t'.
lnet_nid_it will eventually be removed. Where lnet_nid_t is often
passed around by value, 'struct lnet_nid' will normally be passed
around by reference as it is over twice as large.
The net_type field, which currently has value up to 16, is now limited
to 0-254 with 255 being used as a wildcard. The most significant byte
is now a size field which gives the size of the whole nid minus 8. So
zero is correct for current nids with 4-byte addresses.
Where we still need to use 4-byte-address nids, we will use names
containing "nid4". So "nid4" is a lnet_nid_t when "nid" is a struct
lnet_nid. lnet_nid_to_nid4 converts a 'struct lnet_nid' to an
lnet_nid_t.
While lnet_nid_t is stored and often transmitted in host-endian format
(and possibly byte-swapped on receipt), 'struct lnet_nid' is always
stored in network-byte-order (i.e. big-endian). This is more common
approach for network addresses.
In this first instance, 'struct lnet_nid' is used for ni_nid in
'struct lnet_ni', and related support functions.
In particular libcfs_nidstr() is introduced which parallels
libcfs_nid2str(), but takes 'struct lnet_nid'.
In cases were we need to have similar functions for old and new style
nid, the new function is introduced with a slightly different name,
such as libcfs_nid2str above, or LNET_NID_NET (like LNET_NIDNET).
It will be confusing having both, but the plan is to remove the old
names as soon as practical.

To: Andreas Dilger, Oleg Drokin, NeilBrown; +Cc: Lustre Development List
From: Mr NeilBrown <neilb@suse.de>
New entries for struct netstrfns:
nf_addr2str_size
nf_str2addr_size
which accept or report the size of the address in bytes.
New matching functions that can report or parse IPv4 and IPv6
addresses.
New interface - currently unused - libcfs_strnid() which takes a str
and provides a 'struct lnet_nid' with appropriate nid_size.

From: Mr NeilBrown <neilb@suse.de>
The hash_table library requires a "long" to be used as a key. We
currently provide the nid, which at 64bits is a suitable long on 64bit
hosts, but isn't really correct on 32bit hosts.
When we change to an extend nid (which is 160bits) it will be even
less appropriate.
So create a separate function to compute a 'long' key, and implement
by simply xoring 'long'-sized parts of the nid together. On a 64bit
machine, this is currently optimized away for lnet_nid_t, but that
will change when we convert to struct lnet_nid.
This new function is placed in lnet-types.h as it will be more
generally useful later.
The hash_table library calls hash_long() on the key, so we don't need
to do anything more interesting than xoring.

struct lnet_processid (without the '_') is like lnet_process_id, but
contains a 'struct lnet_nid' rather than lnet_nid_t.
So far it is only used for ksnp_id in struct ksock_peer_ni, and
related functions.

From: James Simmons @ 2021-09-22 2:19 UTC (permalink / raw)
To: Andreas Dilger, Oleg Drokin, NeilBrown; +Cc: Lustre Development List
From: Mr NeilBrown <neilb@suse.de>
This patch introduces a version-2 of the acceptor protocol. This
version uses a 'struct lnet_nid' rather than 'lnet_nid_t'
lnet_connect() now accepts a struct lnet_nid and uses version 2 if
necessary. lnet_accept() accepts either v1 or v2.
WC-bug-id: https://jira.whamcloud.com/browse/LU-10391

conflict to each other what leads to:
ASSERTION( atomic_read(&imp->imp_replay_inflight) == 1 )
replay_lock_interpret() does ptlrpc_connect_import() on error, and one
thread will appear starting with connect reply interpret.
replay_lock_interpret() also wakes up ldlm_lock_replay_thread() which
does ptlrpc_import_recovery_state_machine().
It may happen that both threads will get to ldlm_replay_locks() on the
next round at the same time, both increment imp_replay_inflight and
the second one will assert.
The problem appeared in LU-13600 which added ldlm_lock_replay_thread()
with the ptlrpc_import_recovery_state_machine() call.

When there is no valid dentry found for a file we want to
open, we perform a full lookup, which goes to the server
and looks up the file by name. When we find an existing
dentry in cache *but the file is not open on the node*, we
do not do a full lookup. We move directly to opening the
file.
When we open files, we use the FID of the file. The
problem occurs when a new file is renamed *over* the file
we were trying to open. This removes the FID we are
trying to open, but the file *name* userspace called open()
on is still present. In this case, we will return ENOENT,
even though there is a file matching the name used in the
open() call.
The solution is when we get an ENOENT on open (indicating
our open raced with an unlink), we always send ESTALE back
to the VFS, which restarts the open and forces a lookup to
the server (by forcing Lustre to consider the dentry
invalid, see comments in ll_intent_file_open and code in
ll_revalidate_dentry).
This causes a lookup by name, which will correctly handle
the rename, allowing the open to proceed normally.
This should only generate extra retries in the case where a
positive dentry exists on the client but the file has been
removed on the server, ie, open racing with unlink.
This should hopefully be rare.

Due to matching only the device index, link detection implemented
in LU-14742 has issues with confusing the link events for the
virtual interfaces with the link events for the interface that
LNet was actually configured to use. Fix this by improving
the identification of the event source: use both device name and
device index.
Also, to make sure the link fatal state is cleared only when
the device is bound to the IP address used at NI creation,
subscribe to inetaddr events in addition to the netdev events.

In case of error filemap_fault unlock mutex vma->vm_mm->mmap_sem,
so touching vma is dangerous, it could be reused or freed.
The patch uses local file variable to skip vma.

rhashtable_walk_next() can return -EAGAIN when concurrent resizing
has happened. so the callers should check for this error and just
repeat rhashtable_walk_next().

On client side, call the appropriate fscrypt primitives for llite,
to proceed with filename encryption before sending requests to servers
and filename decryption upon request receipt.
Note we need specific overlay functions to handle encoding and
decoding of encrypted filenames, as we do not want server side to deal
with binary names before they reach the backend file system layer.
On server side, mainly the OSD layer, we need to know the encryption
status of files being processed.
If an object belongs to an encrypted file, the filename has been
encoded by the client because it is binary, so it needs to be decoded
before being handed over to the backend file system layer.
And conversely, the filename of an encrypted file has to be encoded
before being sent over the wire.
Note server side is osd-ldiskfs only for now.

To: Andreas Dilger, Oleg Drokin, NeilBrown; +Cc: Lustre Development List
This covers all the UAPI problems outside of the user land
wiretest utility. One set of problems is build and the second is
that UAPI header definitions are either user land only or never
used to valid data going to or from user land.
1) Use UAPI header definitions to validate data send to or from
kernel space. We check lum_hash_type using LMV_HASH_TYPE_MASK.
This avoids a round trip to the server which will report back
an error. The other case is we check the values returned for
LL_IOC_HSM_ACTION. We keep the original behavior of passing
unknown data to the user land application but add debug
logging if the data looks corrupt to help track down bug
issues.
2) We can use QIF_DQBLKSIZE* instead of Lustre specific values
for our quota handling. QIF_DQBLKSIZE* is a Linux UAPI quota
value.

To: Andreas Dilger, Oleg Drokin, NeilBrown; +Cc: Lustre Development List
Both the kernel and userland utility wiretest is used by both
client and server to validate data being sent over the network.
Make userland wiretest buildable on the native Linux client
which lacks server specific data structures. Use of the UAPI
values to hardern testing of user land data passed to the
kernel.

From: Qian Yingjin <qian@ddn.com>
VM area marked with VM_WRITE means that pages may be written, but
mmap page write may never happen.
It should delay layout write until the actual modification on the
file happen in ->page_mkwrite().
Otherwise, it will trigger panic for PCC-RO sanity-pcc test_21f().
