In smb3_reconfigure(), if smb3_sync_session_ctx_passwords() fails, the
function returns immediately without freeing and erasing the newly
allocated new_password and new_password2. This causes both a memory leak
and a potential information leak.
Fix this by calling kfree_sensitive() on both password buffers before
returning in this error case.

When the client re-establishes connection to the server, it will queue
a worker thread that will attempt to reconnect sessions and tcons on
every two seconds, which is kinda overkill as it is a very common
scenario when having expired passwords or KRB5 TGT tickets, or deleted
shares.
Use an exponential backoff strategy to handle session/tcon reconnect
attempts in the worker thread to prevent the client from overloading
the system when it is very unlikely to re-establish any session/tcon
soon while client is idle.

If a DIO read or an unbuffered read request extends beyond the EOF, the
server will return a short read and a status code indicating that EOF was
hit, which gets translated to -ENODATA. Note that the client does not cap
the request at i_size, but asks for the amount requested in case there's a
race on the server with a third party.
Now, on the client side, the request will get split into multiple
subrequests if rsize is smaller than the full request size. A subrequest
that starts before or at the EOF and returns short data up to the EOF will
be correctly handled, with the NETFS_SREQ_HIT_EOF flag being set,
indicating to netfslib that we can't read more.
If a subrequest, however, starts after the EOF and not at it, HIT_EOF will
not be flagged, its error will be set to -ENODATA and it will be abandoned.
This will cause the request as a whole to fail with -ENODATA.
Fix this by setting NETFS_SREQ_HIT_EOF on any subrequest that lies beyond
the EOF marker.

Previously, the client did not update a session's channel state when
multichannel or max_channels mount options were changed via remount.
This led to inconsistent behavior and prevented enabling or disabling
multichannel support without a full unmount/remount cycle.
Enable dynamic reconfiguration of multichannel and max_channels during
remount by:
- Introducing smb3_sync_ses_chan_max(), a centralized function for
channel updates which synchronizes the session's channels with the
updated configuration.
- Replacing cifs_disable_secondary_channels() with
cifs_decrease_secondary_channels(), which accepts a disable_mchan
flag to support multichannel disable when the server stops supporting
multichannel.
- Updating remount logic to detect changes in multichannel or
max_channels and trigger appropriate session/channel updates.
Current limitation:
- The query_interfaces worker runs even when max_channels=1 so that
multichannel can be enabled later via remount without requiring an
unmount. This is a temporary approach and may be refined in the
future.
Users can safely modify multichannel and max_channels on an existing
mount. The client will correctly adjust the session's channel state to
match the new configuration, preserving durability where possible and
avoiding unnecessary disconnects.

Make some preparatory cleanups prior to running a script to organise the
function declarations within the fs/smb/client/ headers. These include:
(1) Remove "inline" from the dummy cifs_proc_init/clean() functions as
they are in a .c file.
(2) Move should_compress()'s kdoc comment to the .c file and remove kdoc
markers from the comments.
(3) Rename CIFS_ALLOW_INSECURE_LEGACY in #endif comments to have CONFIG_
on the front to allow the script to recognise it.
(4) Don't let comments have bare words at the left margin as that confused
the simplistic function detection code in the script.
(5) Adjust some argument lists so that when and if the cleanup script is
run they don't end up over 100 chars.
(6) Fix a few comments to have missing '*' added or the "*/" moved to
their own lines so that checkpatch doesn't moan over the cleanup
script patch.
(7) Move struct cifs_calc_sig_ctx to cifsglob.h.
(8) Remove some __KERNEL__ conditionals.

Add a tracepoint to log EIO errors and give it the capacity to convey up to
two integers of information. This is then wrapped with three functions:
int smb_EIO(enum smb_eio_trace trace)
int smb_EIO1(enum smb_eio_trace trace, unsigned long info)
int smb_EIO2(enum smb_eio_trace trace, unsigned long info,
unsigned long info2)
depending on how many bits of info are desired to be logged with any
particular trace. The functions all return -EIO and can be used in place
of -EIO.
The trace argument is an enum value that gets translated to a string when
the trace is printed.
This makes is easier to log EIO instances when the client is under high
load than turning on a printk wrapper such as cifs_dbg(). Granted, EIO
could have its own separate EIO printing since EIO shouldn't happen.

Replace the smb1 transport's SendReceiveBlockingLock() with SendReceive()
plus a couple of flags. This will then allow that to pick up the transport
changes there.
The first flag, CIFS_INTERRUPTIBLE_WAIT, is added to indicate that the wait
should be interruptible and the second, CIFS_WINDOWS_LOCK, indicates that
we need to send a Lock command with unlock type rather than a Cancel.
send_lock_cancel() is then called from cifs_lock_cancel() which is called
from the main transport loop in compound_send_recv().

Remove the RFC1002 header from struct smb_hdr as used for SMB-1.0. This
simplifies the SMB-1.0 code by simplifying a lot of places that have to add
or subtract 4 to work around the fact that the RFC1002 header isn't really
part of the message and the base for various offsets within the message is
from the base of the smb_hdr, not the RFC1002 header.
Further, clean up a bunch of places that require an extra kvec struct
specifically pointing to the RFC1002 header, such that kvec[0].iov_base
must be exactly 4 bytes before kvec[1].iov_base.
This allows the header preamble size stuff to be removed too.
The size of the request and response message are then handed around either
directly or by summing the size of all the iov_len members in the kvec
array for which we have a count.
Also, this simplifies and cleans up the common transmission and receive
paths for SMB1 and SMB2/3 as there no longer needs to be special handling
casing for SMB1 messages as the RFC1002 header is now generated on the fly
for SMB1 as it is for SMB2/3.

Previously, the behavior of the multichannel and max_channels mount
options was inconsistent and order-dependent. For example, specifying
"multichannel,max_channels=1" would result in 2 channels, while
"max_channels=1,multichannel" would result in 1 channel. Additionally,
conflicting combinations such as "nomultichannel,max_channels=3" or
"multichannel,max_channels=1" did not produce errors and could lead to
unexpected channel counts.
This commit introduces two new fields in smb3_fs_context to explicitly
track whether multichannel and max_channels were specified during
mount. The option parsing and validation logic is updated to ensure:
- The outcome is no longer dependent on the order of options.
- Conflicting combinations (e.g., "nomultichannel,max_channels=3" or
"multichannel,max_channels=1") are detected and result in an error.
- The number of channels created is consistent with the specified
options.
This improves the reliability and predictability of mount option
handling for SMB3 multichannel support.

Pull networking updates from Jakub Kicinski:
"Core & protocols:
- Replace busylock at the Tx queuing layer with a lockless list.
Resulting in a 300% (4x) improvement on heavy TX workloads, sending
twice the number of packets per second, for half the cpu cycles.
- Allow constantly busy flows to migrate to a more suitable CPU/NIC
queue.
Normally we perform queue re-selection when flow comes out of idle,
but under extreme circumstances the flows may be constantly busy.
Add sysctl to allow periodic rehashing even if it'd risk packet
reordering.
- Optimize the NAPI skb cache, make it larger, use it in more paths.
- Attempt returning Tx skbs to the originating CPU (like we already
did for Rx skbs).
- Various data structure layout and prefetch optimizations from Eric.
- Remove ktime_get() from the recvmsg() fast path, ktime_get() is
sadly quite expensive on recent AMD machines.
- Extend threaded NAPI polling to allow the kthread busy poll for
packets.
- Make MPTCP use Rx backlog processing. This lowers the lock
pressure, improving the Rx performance.
- Support memcg accounting of MPTCP socket memory.
- Allow admin to opt sockets out of global protocol memory accounting
(using a sysctl or BPF-based policy). The global limits are a poor
fit for modern container workloads, where limits are imposed using
cgroups.
- Improve heuristics for when to kick off AF_UNIX garbage collection.
- Allow users to control TCP SACK compression, and default to 33% of
RTT.
- Add tcp_rcvbuf_low_rtt sysctl to let datacenter users avoid
unnecessarily aggressive rcvbuf growth and overshot when the
connection RTT is low.
- Preserve skb metadata space across skb_push / skb_pull operations.
- Support for IPIP encapsulation in the nftables flowtable offload.
- Support appending IP interface information to ICMP messages (RFC
5837).
- Support setting max record size in TLS (RFC 8449).
- Remove taking rtnl_lock from RTM_GETNEIGHTBL and RTM_SETNEIGHTBL.
- Use a dedicated lock (and RCU) in MPLS, instead of rtnl_lock.
- Let users configure the number of write buffers in SMC.
- Add new struct sockaddr_unsized for sockaddr of unknown length,
from Kees.
- Some conversions away from the crypto_ahash API, from Eric Biggers.
- Some preparations for slimming down struct page.
- YAML Netlink protocol spec for WireGuard.
- Add a tool on top of YAML Netlink specs/lib for reporting commonly

Pull directory delegations update from Christian Brauner:
"This contains the work for recall-only directory delegations for
knfsd.
Add support for simple, recallable-only directory delegations. This
was decided at the fall NFS Bakeathon where the NFS client and server
maintainers discussed how to merge directory delegation support.
The approach starts with recallable-only delegations for several reasons:
1. RFC8881 has gaps that are being addressed in RFC8881bis. In
particular, it requires directory position information for
CB_NOTIFY callbacks, which is difficult to implement properly
under Linux. The spec is being extended to allow that information
to be omitted.
2. Client-side support for CB_NOTIFY still lags. The client side
involves heuristics about when to request a delegation.
3. Early indication shows simple, recallable-only delegations can
help performance. Anna Schumaker mentioned seeing a multi-minute
speedup in xfstests runs with them enabled.
With these changes, userspace can also request a read lease on a
directory that will be recalled on conflicting accesses. This may be
useful for applications like Samba. Users can disable leases
altogether via the fs.leases-enable sysctl if needed.
VFS changes:
- Dedicated Type for Delegations
Introduce struct delegated_inode to track inodes that may have
delegations that need to be broken. This replaces the previous
approach of passing raw inode pointers through the delegation
breaking code paths, providing better type safety and clearer
semantics for the delegation machinery.
- Break parent directory delegations in open(..., O_CREAT) codepath
- Allow mkdir to wait for delegation break on parent
- Allow rmdir to wait for delegation break on parent
- Add try_break_deleg calls for parents to vfs_link(), vfs_rename(),
and vfs_unlink()
- Make vfs_create(), vfs_mknod(), and vfs_symlink() break delegations
on parent directory
- Clean up argument list for vfs_create()
- Expose delegation support to userland
Filelock changes:
- Make lease_alloc() take a flags argument
- Rework the __break_lease API to use flags
- Add struct delegated_inode
- Push the S_ISREG check down to ->setlease handlers
- Lift the ban on directory leases in generic_setlease
NFSD changes:
- Allow filecache to hold S_IFDIR files
- Allow DELEGRETURN on directories
- Wire up GET_DIR_DELEGATION handling
Fixes:
- Fix kernel-doc warnings in __fcntl_getlease
- Add needed headers for new struct delegation definition"

Pull fs header updates from Christian Brauner:
"This contains initial work to start splitting up fs.h.
Begin the long-overdue work of splitting up the monolithic fs.h
header. The header has grown to over 3000 lines and includes types and
functions for many different subsystems, making it difficult to
navigate and causing excessive compilation dependencies.
This series introduces new focused headers for superblock-related
code:
- Rename fs_types.h to fs_dirent.h to better reflect its actual
content (directory entry types)
- Add fs/super_types.h containing superblock type definitions
- Add fs/super.h containing superblock function declarations
This is the first step in a longer effort to modularize the VFS
headers.
Cleanups:
- Inode Field Layout Optimization (Mateusz Guzik)
Move inode fields used during fast path lookup closer together to
improve cache locality during path resolution.
- current_umask() Optimization (Mateusz Guzik)
Inline current_umask() and move it to fs_struct.h. This improves
performance by avoiding function call overhead for this
frequently-used function, and places it in a more appropriate
header since it operates on fs_struct"

Pull cred guard updates from Christian Brauner:
"This contains substantial credential infrastructure improvements
adding guard-based credential management that simplifies code and
eliminates manual reference counting in many subsystems.
Features:
- Kernel Credential Guards
Add with_kernel_creds() and scoped_with_kernel_creds() guards that
allow using the kernel credentials without allocating and copying
them. This was requested by Linus after seeing repeated
prepare_kernel_creds() calls that duplicate the kernel credentials
only to drop them again later.
The new guards completely avoid the allocation and never expose the
temporary variable to hold the kernel credentials anywhere in
callers.
- Generic Credential Guards
Add scoped_with_creds() guards for the common override_creds() and
revert_creds() pattern. This builds on earlier work that made
override_creds()/revert_creds() completely reference count free.
- Prepare Credential Guards
Add prepare credential guards for the more complex pattern of
preparing a new set of credentials and overriding the current
credentials with them:
- prepare_creds()
- modify new creds
- override_creds()
- revert_creds()
- put_cred()
Cleanups:
- Make init_cred static since it should not be directly accessed
- Add kernel_cred() helper to properly access the kernel credentials
- Fix scoped_class() macro that was introduced two cycles ago
- coredump: split out do_coredump() from vfs_coredump() for cleaner
credential handling
- coredump: move revert_cred() before coredump_cleanup()
- coredump: mark struct mm_struct as const

Pull vfs inode updates from Christian Brauner:
"Features:
- Hide inode->i_state behind accessors. Open-coded accesses prevent
asserting they are done correctly. One obvious aspect is locking,
but significantly more can be checked. For example it can be
detected when the code is clearing flags which are already missing,
or is setting flags when it is illegal (e.g., I_FREEING when
->i_count > 0)
- Provide accessors for ->i_state, converts all filesystems using
coccinelle and manual conversions (btrfs, ceph, smb, f2fs, gfs2,
overlayfs, nilfs2, xfs), and makes plain ->i_state access fail to
compile
- Rework I_NEW handling to operate without fences, simplifying the
code after the accessor infrastructure is in place
Cleanups:
- Move wait_on_inode() from writeback.h to fs.h
- Spell out fenced ->i_state accesses with explicit smp_wmb/smp_rmb
for clarity
- Cosmetic fixes to LRU handling
- Push list presence check into inode_io_list_del()
- Touch up predicts in __d_lookup_rcu()
- ocfs2: retire ocfs2_drop_inode() and I_WILL_FREE usage
- Assert on ->i_count in iput_final()
- Assert ->i_lock held in __iget()

- Add missing fences to I_NEW handling"

and smbd_conn_upcall()
sc->first_error might already be set and sc->status
is thus unexpected, so this should avoid the WARN[_ON]_ONCE()
if sc->first_error is already set and have a usable error path.
While there set sc->first_error as soon as possible.
This is done based on a problem seen in similar places on
the server. And there it was already very useful in order
to find the problem when we have a meaningful WARN_ONCE()
that prints details about the connection.
