commit 10bc8e4af65946b727728d7479c028742321b60a upstream.
[backport comments for pre v5.15:
- ksmbd mentions are irrelevant - ksmbd hunks were dropped
- sb_write_started() is missing - assert was dropped
]
Commit 868f9f2f8e00 ("vfs: fix copy_file_range() regression in cross-fs
copies") removed fallback to generic_copy_file_range() for cross-fs
cases inside vfs_copy_file_range().
To preserve behavior of nfsd and ksmbd server-side-copy, the fallback to
generic_copy_file_range() was added in nfsd and ksmbd code, but that
call is missing sb_start_write(), fsnotify hooks and more.
Ideally, nfsd and ksmbd would pass a flag to vfs_copy_file_range() that
will take care of the fallback, but that code would be subtle and we got
vfs_copy_file_range() logic wrong too many times already.
Instead, add a flag to explicitly request vfs_copy_file_range() to
perform only generic_copy_file_range() and let nfsd and ksmbd use this
flag only in the fallback path.
This choise keeps the logic changes to minimum in the non-nfsd/ksmbd code
paths to reduce the risk of further regressions.

commit 868f9f2f8e004bfe0d3935b1976f625b2924893b upstream.
[backport comments for pre v5.15:
- This commit has a bug fixed by commit 10bc8e4af659 ("vfs: fix
copy_file_range() averts filesystem freeze protection")
- ksmbd mentions are irrelevant - ksmbd hunks were dropped
]
A regression has been reported by Nicolas Boichat, found while using the
copy_file_range syscall to copy a tracefs file.
Before commit 5dae222a5f ("vfs: allow copy_file_range to copy across
devices") the kernel would return -EXDEV to userspace when trying to
copy a file across different filesystems. After this commit, the
syscall doesn't fail anymore and instead returns zero (zero bytes
copied), as this file's content is generated on-the-fly and thus reports
a size of zero.
Another regression has been reported by He Zhe - the assertion of
WARN_ON_ONCE(ret == -EOPNOTSUPP) can be triggered from userspace when
copying from a sysfs file whose read operation may return -EOPNOTSUPP.
Since we do not have test coverage for copy_file_range() between any two
types of filesystems, the best way to avoid these sort of issues in the
future is for the kernel to be more picky about filesystems that are
allowed to do copy_file_range().
This patch restores some cross-filesystem copy restrictions that existed
prior to commit 5dae222a5f ("vfs: allow copy_file_range to copy across
devices"), namely, cross-sb copy is not allowed for filesystems that do
not implement ->copy_file_range().
Filesystems that do implement ->copy_file_range() have full control of
the result - if this method returns an error, the error is returned to
the user. Before this change this was only true for fs that did not
implement the ->remap_file_range() operation (i.e. nfsv3).
Filesystems that do not implement ->copy_file_range() still fall-back to
the generic_copy_file_range() implementation when the copy is within the
same sb. This helps the kernel can maintain a more consistent story
about which filesystems support copy_file_range().
nfsd and ksmbd servers are modified to fall-back to the
generic_copy_file_range() implementation in case vfs_copy_file_range()
fails with -EOPNOTSUPP or -EXDEV, which preserves behavior of
server-side-copy.
fall-back to generic_copy_file_range() is not implemented for the smb
operation FSCTL_DUPLICATE_EXTENTS_TO_FILE, which is arguably a correct
change of behavior.

[ Upstream commit 019805fea91599b22dfa62ffb29c022f35abeb06 ]
Use-after-free occurred when the laundromat tried to free expired
cpntf_state entry on the s2s_cp_stateids list after inter-server
copy completed. The sc_cp_list that the expired copy state was
inserted on was already freed.
When COPY completes, the Linux client normally sends LOCKU(lock_state x),
FREE_STATEID(lock_state x) and CLOSE(open_state y) to the source server.
The nfs4_put_stid call from nfsd4_free_stateid cleans up the copy state
from the s2s_cp_stateids list before freeing the lock state's stid.
However, sometimes the CLOSE was sent before the FREE_STATEID request.
When this happens, the nfsd4_close_open_stateid call from nfsd4_close
frees all lock states on its st_locks list without cleaning up the copy
state on the sc_cp_list list. When the time the FREE_STATEID arrives the
server returns BAD_STATEID since the lock state was freed. This causes
the use-after-free error to occur when the laundromat tries to free
the expired cpntf_state.
This patch adds a call to nfs4_free_cpntf_statelist in
nfsd4_close_open_stateid to clean up the copy state before calling
free_ol_stateid_reaplist to free the lock state's stid on the reaplist.

commit f11ad7aa653130b71e2e89bed207f387718216d5 upstream.
RFC 8881 explains the purpose of the write verifier this way:
> The final portion of the result is the field writeverf. This field
> is the write verifier and is a cookie that the client can use to
> determine whether a server has changed instance state (e.g., server
> restart) between a call to WRITE and a subsequent call to either
> WRITE or COMMIT.
But then it says:
> This cookie MUST be unchanged during a single instance of the
> NFSv4.1 server and MUST be unique between instances of the NFSv4.1
> server. If the cookie changes, then the client MUST assume that
> any data written with an UNSTABLE4 value for committed and an old
> writeverf in the reply has been lost and will need to be
> recovered.
RFC 1813 has similar language for NFSv3. NFSv2 does not have a write
verifier since it doesn't implement the COMMIT procedure.
Since commit 19e0663ff9 ("nfsd: Ensure sampling of the write
verifier is atomic with the write"), the Linux NFS server has
returned a boot-time-based verifier for UNSTABLE WRITEs, but a zero
verifier for FILE_SYNC and DATA_SYNC WRITEs. FILE_SYNC and DATA_SYNC
WRITEs are not followed up with a COMMIT, so there's no need for
clients to compare verifiers for stable writes.
However, by returning a different verifier for stable and unstable
writes, the above commit puts the Linux NFS server a step farther
out of compliance with the first MUST above. At least one NFS client
(FreeBSD) noticed the difference, making this a potential
regression.
[Removed down_write to fix the conflict in the cherry-pick. The
down_write functionality was no longer needed there. Upstream commit
555dbf1a9aac6d3150c8b52fa35f768a692f4eeb titled nfsd: Replace use of
rwsem with errseq_t removed those and replace it with new functionality
that was more scalable. This commit is already backported onto 5.10 and
so removing down_write ensures consistency with that change. Tested by
compiling and booting successfully. - kochera]

commit 8a9ffb8c857c2c99403bd6483a5a005fed5c0773 upstream.
commit 555dbf1a9aac ("nfsd: Replace use of rwsem with errseq_t")
incidentally broke translation of -EINVAL to nfserr_notsupp.
The patch restores that.

commit 555dbf1a9aac6d3150c8b52fa35f768a692f4eeb upstream.
The nfsd_file nf_rwsem is currently being used to separate file write
and commit instances to ensure that we catch errors and apply them to
the correct write/commit.
We can improve scalability at the expense of a little accuracy (some
extra false positives) by replacing the nf_rwsem with more careful
use of the errseq_t mechanism to track errors across the different
operations.

commit ce3c4ad7f4ce5db7b4f08a1e237d8dd94b39180b upstream.
nfsd4_release_lockowner() holds clp->cl_lock when it calls
check_for_locks(). However, check_for_locks() calls nfsd_file_get()
/ nfsd_file_put() to access the backing inode's flc_posix list, and
nfsd_file_put() can sleep if the inode was recently removed.
Let's instead rely on the stateowner's reference count to gate
whether the release is permitted. This should be a reliable
indication of locks-in-use since file lock operations and
->lm_get_owner take appropriate references, which are released
appropriately when file locks are removed.

These have been incorrect since the function was introduced.
A proper kerneldoc comment is added since this function, though
static, is part of an external interface.

[ Upstream commit 4d2eeafecd6c83b4444db3dc0ada201c89b1aa44 ]
The nfsd file cache table can be pretty large and its allocation
may require as many as 80 contigious pages.
Employ the same fix that was employed for similar issue that was
reported for the reply cache hash table allocation several years ago

commit 6a4d333d540041d244b2fca29b8417bfde20af81 upstream.

commit 6260d9a56ab352b54891ec66ab0eced57d55abc6 upstream.
Ensure that a client cannot specify a WRITE range that falls in a
byte range outside what the kernel's internal types (such as loff_t,
which is signed) can represent. The kiocb iterators, invoked in
nfsd_vfs_write(), should properly limit write operations to within
the underlying file system's s_maxbytes.

commit ab451ea952fe9d7afefae55ddb28943a148247fe upstream.
From RFC 7530 Section 16.34.5:
o The server has not recorded an unconfirmed { v, x, c, *, * } and
has recorded a confirmed { v, x, c, *, s }. If the principals of
the record and of SETCLIENTID_CONFIRM do not match, the server
returns NFS4ERR_CLID_INUSE without removing any relevant leased
client state, and without changing recorded callback and
callback_ident values for client { x }.
The current code intends to do what the spec describes above but
it forgot to set 'old' to NULL resulting to the confirmed client
to be expired.

commit 29044dae2e746949ad4b9cbdbfb248994d1dcdb4 upstream.
Commit 49246466a9 ("fsnotify: move fsnotify_nameremove() hook out of
d_delete()") moved the fsnotify delete hook before d_delete() so fsnotify
will have access to a positive dentry.
This allowed a race where opening the deleted file via cached dentry
is now possible after receiving the IN_DELETE event.
To fix the regression in pseudo filesystems, convert d_delete() calls
to d_drop() (see commit 46c46f8df9 ("devpts_pty_kill(): don't bother
with d_delete()") and move the fsnotify hook after d_drop().
Add a missing fsnotify_unlink() hook in nfsdfs that was found during
the audit of fsnotify hooks in pseudo filesystems.
Note that the fsnotify hooks in simple_recursive_removal() follow
d_invalidate(), so they require no change.

We have namespaces, so use them for all vfs-exported namespaces so that
filesystems can use them, but not anything else.
Some in-kernel drivers that do direct filesystem accesses (because they
serve up files) are also allowed access to these symbols to keep 'make
allmodconfig' builds working properly, but it is not needed for Android
kernel images.

commit 548ec0805c399c65ed66c6641be467f717833ab5 upstream.
A delegation break could arrive as soon as we've called vfs_setlease. A
delegation break runs a callback which immediately (in
nfsd4_cb_recall_prepare) adds the delegation to del_recall_lru. If we
then exit nfs4_set_delegation without hashing the delegation, it will be
freed as soon as the callback is done with it, without ever being
removed from del_recall_lru.
Symptoms show up later as use-after-free or list corruption warnings,
usually in the laundromat thread.
I suspect aba2072f4523 "nfsd: grant read delegations to clients holding
writes" made this bug easier to hit, but I looked as far back as v3.0
and it looks to me it already had the same problem. So I'm not sure
where the bug was introduced; it may have been there from the beginning.

If nfsd has existing listening sockets without any processes, then an error
returned from svc_create_xprt() for an additional transport will remove
those existing listeners. We're seeing this in practice when userspace
attempts to create rpcrdma transports without having the rpcrdma modules
present before creating nfsd kernel processes. Fix this by checking for
existing sockets before calling nfsd_destroy().

commit 1d625050c7c2dd877e108e382b8aaf1ae3cfe1f4 upstream.
init_nfsd() should not unregister pernet subsys if the register fails
but should instead unwind from the last successful operation which is
register_filesystem().
Unregistering a failed register_pernet_subsys() call can result in
a kernel GPF as revealed by programmatically injecting an error in
register_pernet_subsys().
Verified the fix handled failure gracefully with no lingering nfsd
entry in /proc/filesystems. This change was introduced by the commit
bd5ae9288d64 ("nfsd: register pernet ops last, unregister first"),
the original error handling logic was correct.

seconds of the copy starting, instead of giving the copy a full lease

commit 6ee65a773096ab3f39d9b00311ac983be5bdeb7c upstream.
This reverts commit 94415b06eb.
That commit claimed to allow a client to get a read delegation when it
was the only writer. Actually it allowed a client to get a read
delegation when *any* client has a write open!
The main problem is that it's depending on nfs4_clnt_odstate structures
that are actually only maintained for pnfs exports.
This causes clients to miss writes performed by other clients, even when
there have been intervening closes and opens, violating close-to-open
cache consistency.
We can do this a different way, but first we should just revert this.
I've added pynfs 4.1 test DELEG19 to test for this, as I should have
done originally!

These pernet operations may depend on stuff set up or torn down in the
module init/exit functions. And they may be called at any time in
between. So it makes more sense for them to be the last to be
registered in the init function, and the first to be unregistered in the
exit function.
In particular, without this, the drc slab is being destroyed before all
the per-net drcs are shut down, resulting in an "Objects remaining in
nfsd_drc on __kmem_cache_shutdown()" warning in exit_nfsd.
