Now that napi_schedule return a bool, we can drop napi_reschedule that
does the same exact function. The function comes from a very old commit
bfe13f54f5 ("ibm_emac: Convert to use napi_struct independent of struct
net_device") and the purpose is actually deprecated in favour of
different logic.
Convert every user of napi_reschedule to napi_schedule.

Initialize the structure to 0 so that it's fields won't have random
values. For example fields like rec.traffic_class (as well as
rec.flow_label and rec.sl) is used to generate the user AH through:
cma_iboe_join_multicast
cma_make_mc_event
ib_init_ah_from_mcmember
And a random traffic_class causes a random IP DSCP in RoCEv2.

After the change to use dynamic cache structure, new cache entries
can be added and the mkey allocation can no longer assume that all
mkeys created for the cache have access_flags equal to zero.
Example of a flow that exposes the issue:
A user registers MR with RO on a HCA that cannot UMR RO and the mkey is
created outside of the cache. When the user deregisters the MR, a new
cache entry is created to store mkeys with RO.
Later, the user registers 2 MRs with RO. The first MR is reused from the
new cache entry. When we try to get the second mkey from the cache we see
the entry is empty so we go to the MR cache mkey allocation flow which
would have allocated a mkey with no access flags, resulting the user getting
a MR without RO.

Flag that indicate control path command completion should be cleared
only after copying the command response data. As soon as the is_in_used
flag is clear, the waiting thread can proceed with wrong response
data. This wrong data is causing multiple issues like wrong lkey
used in data traffic and wrong AH Id etc.
Use a memory barrier to ensure that the response data
is copied and visible to the process waiting on a different
cpu core before clearing the is_in_used flag.

In case immediate MPA request processing fails, the newly
created endpoint unlinks the listening endpoint and is
ready to be dropped. This special case was not handled
correctly by the code handling the later TCP socket close,
causing a NULL dereference crash in siw_cm_work_handler()
when dereferencing a NULL listener. We now also cancel
the useless MPA timeout, if immediate MPA request
processing fails.
This patch furthermore simplifies MPA processing in general:
Scheduling a useless TCP socket read in sk_data_ready() upcall
is now surpressed, if the socket is already moved out of
TCP_ESTABLISHED state.

After scmd_eh_abort_handler() has called the SCSI LLD eh_abort_handler
callback, it performs one of the following actions:
* Call scsi_queue_insert().
* Call scsi_finish_command().
* Call scsi_eh_scmd_add().
Hence, SCSI abort handlers must not call scsi_done(). Otherwise all
the above actions would trigger a use-after-free. Hence remove the
scsi_done() call from srp_abort(). Keep the srp_free_req() call
before returning SUCCESS because we may not see the command again if
SUCCESS is returned.

hns, and bnxt_re
- siw now works over tunnel and other netdevs with a MAC address by
removing assumptions about a MAC/GID from the connection manager
- "Doorbell Pacing" for bnxt_re - this is a best effort scheme to allow
userspace to slow down the doorbell rings if the HW gets full
- irdma egress VLAN priority, better QP/WQ sizing
- rxe bug fixes in queue draining and srq resizing
- Support more ethernet speed options in the core layer
- DMABUF support for bnxt_re
- Multi-stage MTT support for erdma to allow much bigger MR registrations
- A irdma fix with a CVE that came in too late to go to -rc, missing
bounds checking for 0 length MRs

Merge tag 'v6.6-vfs.ctime' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs
Pull vfs timestamp updates from Christian Brauner:
"This adds VFS support for multi-grain timestamps and converts tmpfs,
xfs, ext4, and btrfs to use them. This carries acks from all relevant
filesystems.
The VFS always uses coarse-grained timestamps when updating the ctime
and mtime after a change. This has the benefit of allowing filesystems
to optimize away a lot of metadata updates, down to around 1 per
jiffy, even when a file is under heavy writes.
Unfortunately, this has always been an issue when we're exporting via
NFSv3, which relies on timestamps to validate caches. A lot of changes
can happen in a jiffy, so timestamps aren't sufficient to help the
client decide to invalidate the cache.
Even with NFSv4, a lot of exported filesystems don't properly support
a change attribute and are subject to the same problems with timestamp
granularity. Other applications have similar issues with timestamps
(e.g., backup applications).
If we were to always use fine-grained timestamps, that would improve
the situation, but that becomes rather expensive, as the underlying
filesystem would have to log a lot more metadata updates.
This introduces fine-grained timestamps that are used when they are
actively queried.
This uses the 31st bit of the ctime tv_nsec field to indicate that
something has queried the inode for the mtime or ctime. When this flag
is set, on the next mtime or ctime update, the kernel will fetch a
fine-grained timestamp instead of the usual coarse-grained one.
As POSIX generally mandates that when the mtime changes, the ctime
must also change the kernel always stores normalized ctime values, so
only the first 30 bits of the tv_nsec field are ever used.
Filesytems can opt into this behavior by setting the FS_MGTIME flag in
the fstype. Filesystems that don't set this flag will continue to use
coarse-grained timestamps.
Various preparatory changes, fixes and cleanups are included:
- Fixup all relevant places where POSIX requires updating ctime
together with mtime. This is a wide-range of places and all
maintainers provided necessary Acks.
- Add new accessors for inode->i_ctime directly and change all
callers to rely on them. Plain accesses to inode->i_ctime are now
gone and it is accordingly rename to inode->__i_ctime and commented
as requiring accessors.
- Extend generic_fillattr() to pass in a request mask mirroring in a
sense the statx() uapi. This allows callers to pass in a request
mask to only get a subset of attributes filled in.
- Rework timestamp updates so it's possible to drop the @now
parameter the update_time() inode operation and associated helpers.
- Add inode_update_timestamps() and convert all filesystems to it
removing a bunch of open-coding"

mlx5 MACsec RoCEv2 support
From Patrisious:
This series extends previously added MACsec offload support
to cover RoCE traffic either.
In order to achieve that, we need configure MACsec with offload between
the two endpoints, like below:
REMOTE_MAC=10:70:fd:43:71:c0
* ip addr add 1.1.1.1/16 dev eth2
* ip link set dev eth2 up
* ip link add link eth2 macsec0 type macsec encrypt on
* ip macsec offload macsec0 mac
* ip macsec add macsec0 tx sa 0 pn 1 on key 00 dffafc8d7b9a43d5b9a3dfbbf6a30c16
* ip macsec add macsec0 rx port 1 address $REMOTE_MAC
* ip macsec add macsec0 rx port 1 address $REMOTE_MAC sa 0 pn 1 on key 01 ead3664f508eb06c40ac7104cdae4ce5
* ip addr add 10.1.0.1/16 dev macsec0
* ip link set dev macsec0 up
And in a similar manner on the other machine, while noting the keys order
would be reversed and the MAC address of the other machine.
RDMA traffic is separated through relevant GID entries and in case
of IP ambiguity issue - meaning we have a physical GIDs and a MACsec
GIDs with the same IP/GID, we disable our physical GID in order
to force the user to only use the MACsec GID.

Use a notifier to implement mlx4_dispatch_event() in preparation to
switch mlx4_en and mlx4_ib to be an auxiliary device.
A problem is that if the mlx4_interface.event callback was replaced with
something as mlx4_adrv.event then the implementation of
mlx4_dispatch_event() would need to acquire a lock on a given device
before executing this callback. That is necessary because otherwise
there is no guarantee that the associated driver cannot get unbound when
the callback is running. However, taking this lock is not possible
because mlx4_dispatch_event() can be invoked from the hardirq context.
Using an atomic notifier allows the driver to accurately record when it
wants to receive these events and solves this problem.
A handler registration is done by both mlx4_en and mlx4_ib at the end of
their mlx4_interface.add callback. This matches the current situation
when mlx4_add_device() would enable events for a given device
immediately after this callback, by adding the device on the
mlx4_priv.list.

Function mlx4_dispatch_event() takes an 'unsigned long' as its event
parameter. The actual value is none (MLX4_DEV_EVENT_CATASTROPHIC_ERROR),
a pointer to mlx4_eqe (MLX4_DEV_EVENT_PORT_MGMT_CHANGE), or a 32-bit
integer (remaining events).
In preparation to switch mlx4_en and mlx4_ib to be an auxiliary device,
the mlx4_interface.event callback is replaced with a notifier and
function mlx4_dispatch_event() gets updated to invoke
atomic_notifier_call_chain(). This requires forwarding the input 'param'
value from the former function to the latter. A problem is that the
notifier call takes 'void *' as its 'param' value, compared to
'unsigned long' used by mlx4_dispatch_event(). Re-passing the value
would need either punning it to 'void *' or passing down the address of
the input 'param'. Both approaches create a number of unnecessary casts.
Change instead the input 'param' of mlx4_dispatch_event() from
'unsigned long' to 'void *'. A mlx4_eqe pointer can be passed directly,
callers using an int value are adjusted to pass its address.

Simplify the mlx4 driver interface by removing mlx4_get_protocol_dev()
and the associated mlx4_interface.get_dev callbacks. This is done in
preparation to use an auxiliary bus to model the mlx4 driver structure.
The change is motivated by the following situation:
* The mlx4_en interface is being initialized by mlx4_en_add() and
mlx4_en_activate().
* The latter activate function calls mlx4_en_init_netdev() ->
register_netdev() to register a new net_device.
* A netdev event NETDEV_REGISTER is raised for the device.
* The netdev notififier mlx4_ib_netdev_event() is called and it invokes
mlx4_ib_scan_netdevs() -> mlx4_get_protocol_dev() ->
mlx4_en_get_netdev() [via mlx4_interface.get_dev].
This chain creates a problem when mlx4_en gets switched to be an
auxiliary driver. It contains two device calls which would both need to
take a respective device lock.
Avoid this situation by updating mlx4_ib_scan_netdevs() to no longer
call mlx4_get_protocol_dev() but instead to utilize the information
passed in net_device.parent and net_device.dev_port. This data is
sufficient to determine that an updated port is one that the mlx4_ib
driver should take care of and to keep mlx4_ib_dev.iboe.netdevs up to
date.
Following that, update mlx4_ib_get_netdev() to also not call
mlx4_get_protocol_dev() and instead scan all current netdevs to find
find a matching one. Note that mlx4_ib_get_netdev() is called early from
ib_register_device() and cannot use data tracked in
mlx4_ib_dev.iboe.netdevs which is not at that point yet set.
Finally, remove function mlx4_get_protocol_dev() and the
mlx4_interface.get_dev callbacks (only mlx4_en_get_netdev()) as they
became unused.

When trying to destroy QP or CQ, we first decrease the refcount and
potentially free memory regions allocated for the object and then
request the device to destroy the object. If the device fails, the
object isn't fully destroyed so the user/IB core can try to destroy the
object again which will lead to underflow when trying to decrease an
already zeroed refcount.
Deallocate resources in reverse order of allocating them to safely free
them.

The siw_connect can go to err in below after cep is allocated successfully:
1. If siw_cm_alloc_work returns failure. In this case socket is not
assoicated with cep so siw_cep_put can't be called by siw_socket_disassoc.
We need to call siw_cep_put twice since cep->kref is increased once after
it was initialized.
2. If siw_cm_queue_work can't find a work, which means siw_cep_get is not
called in siw_cm_queue_work, so cep->kref is increased twice by siw_cep_get
and when associate socket with cep after it was initialized. So we need to
call siw_cep_put three times (one in siw_socket_disassoc).
3. siw_send_mpareqrep returns error, this scenario is similar as 2.
So we need to remove one siw_cep_put in the error path.
