f7e97ce269 v6.6 merge window RDMA pull request
Many small changes across the subystem, some highlights:
 
 - Usual driver cleanups in qedr, siw, erdma, hfi1, mlx4/5, irdma, mthca,
   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

bd6c11bc43 Networking changes for 6.6.
Core
 ----
 
  - Increase size limits for to-be-sent skb frag allocations. This
    allows tun, tap devices and packet sockets to better cope with large
    writes operations.
 
  - Store netdevs in an xarray, to simplify iterating over netdevs.
 
  - Refactor nexthop selection for multipath routes.
 
  - Improve sched class lifetime handling.
 
  - Add backup nexthop ID support for bridge.
 
  - Implement drop reasons support in openvswitch.
 
  - Several data races annotations and fixes.
 
  - Constify the sk parameter of routing functions.
 
  - Prepend kernel version to netconsole message.
 
 Protocols
 ---------
 
  - Implement support for TCP probing the peer being under memory
    pressure.
 
  - Remove hard coded limitation on IPv6 specific info placement
    inside the socket struct.
 
  - Get rid of sysctl_tcp_adv_win_scale and use an auto-estimated
    per socket scaling factor.
 
  - Scaling-up the IPv6 expired route GC via a separated list of
    expiring routes.
 
  - In-kernel support for the TLS alert protocol.
 
  - Better support for UDP reuseport with connected sockets.
 
  - Add NEXT-C-SID support for SRv6 End.X behavior, reducing the SR
    header size.
 
  - Get rid of additional ancillary per MPTCP connection struct socket.
 
  - Implement support for BPF-based MPTCP packet schedulers.
 
  - Format MPTCP subtests selftests results in TAP.
 
  - Several new SMC 2.1 features including unique experimental options,
    max connections per lgr negotiation, max links per lgr negotiation.
 
 BPF
 ---
 
  - Multi-buffer support in AF_XDP.
 
  - Add multi uprobe BPF links for attaching multiple uprobes
    and usdt probes, which is significantly faster and saves extra fds.
 
  - Implement an fd-based tc BPF attach API (TCX) and BPF link support on
    top of it.
 
  - Add SO_REUSEPORT support for TC bpf_sk_assign.
 
  - Support new instructions from cpu v4 to simplify the generated code and
    feature completeness, for x86, arm64, riscv64.
 
  - Support defragmenting IPv(4|6) packets in BPF.
 
  - Teach verifier actual bounds of bpf_get_smp_processor_id()
    and fix perf+libbpf issue related to custom section handling.
 
  - Introduce bpf map element count and enable it for all program types.
 
  - Add a BPF hook in sys_socket() to change the protocol ID
    from IPPROTO_TCP to IPPROTO_MPTCP to cover migration for legacy.
 
  - Introduce bpf_me_mcache_free_rcu() and fix OOM under stress.
 
  - Add uprobe support for the bpf_get_func_ip helper.
 
  - Check skb ownership against full socket.
 
  - Support for up to 12 arguments in BPF trampoline.
 
  - Extend link_info for kprobe_multi and perf_event links.
 
 Netfilter
 ---------
 
  - Speed-up process exit by aborting ruleset validation if a
    fatal signal is pending.
 
  - Allow NLA_POLICY_MASK to be used with BE16/BE32 types.
 
 Driver API
 ----------
 
  - Page pool optimizations, to improve data locality and cache usage.
 
  - Introduce ndo_hwtstamp_get() and ndo_hwtstamp_set() to avoid the need
    for raw ioctl() handling in drivers.
 
  - Simplify genetlink dump operations (doit/dumpit) providing them
    the common information already populated in struct genl_info.
 
  - Extend and use the yaml devlink specs to [re]generate the split ops.
 
  - Introduce devlink selective dumps, to allow SF filtering SF based on
    handle and other attributes.
 
  - Add yaml netlink spec for netlink-raw families, allow route, link and
    address related queries via the ynl tool.
 
  - Remove phylink legacy mode support.
 
  - Support offload LED blinking to phy.
 
  - Add devlink port function attributes for IPsec.

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"

Leon Romanovsky says:

====================
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.

73d68002a0 mlx4: Replace the mlx4_interface.event callback with a notifier
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.

7ba189ac52 mlx4: Use 'void *' as the event param of mlx4_dispatch_event()
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.

71ab55a9af mlx4: Get rid of the mlx4_interface.get_dev callback
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.

dc202c57e9 RDMA/efa: Fix wrong resources deallocation order
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.

58dbd6428a RDMA/mlx5: Handles RoCE MACsec steering rules addition and deletion
Add RoCE MACsec rules when a gid is added for the MACsec netdevice and
handle their cleanup when the gid is removed or the MACsec SA is deleted.
Also support alias IP for the MACsec device, as long as we don't have
more ips than what the gid table can hold.
In addition handle the case where a gid is added but there are still no
SAs added for the MACsec device, so the rules are added later on when
the SAs are added.

758ce14aee RDMA/mlx5: Implement MACsec gid addition and deletion
Handle MACsec IP ambiguity issue, since mlx5 hw can't support
programming both the MACsec and the physical gid when they have the same
IP address, because it wouldn't know to whom to steer the traffic.
Hence in such case we delete the physical gid from the hw gid table,
which would then cause all traffic sent over it to fail, and we'll only
be able to send traffic over the MACsec gid.

f14c1a14e6 net/mlx5: Allocate completion EQs dynamically
This commit enables the dynamic allocation of EQs at runtime, allowing
for more flexibility in managing completion EQs and reducing the memory
overhead of driver load. Whenever a CQ is created for a given vector
index, the driver will lookup to see if there is an already mapped
completion EQ for that vector, if so, utilize it. Otherwise, allocate a
new EQ on demand and then utilize it for the CQ completion events.

Add a protection lock to the EQ table to protect from concurrent EQ
creation attempts.

While at it, replace mlx5_vector2irqn()/mlx5_vector2eqn() with
mlx5_comp_eqn_get() and mlx5_comp_irqn_get() which will allocate an
EQ on demand if no EQ is found for the given vector.

9e03dbea2b RDMA/hns: Fix CQ and QP cache affinity
Currently, the affinity between QP cache and CQ cache is not
considered when assigning QPN, it will affect the message rate of HW.

Allocate QPN from QP cache with better CQ affinity to get better
performance.

706efac447 RDMA/hns: Fix incorrect post-send with direct wqe of wr-list
Currently, direct wqe is not supported for wr-list. RoCE driver excludes
direct wqe for wr-list by judging whether the number of wr is 1.

For a wr-list where the second wr is a length-error atomic wr, the
post-send driver handles the first wr and adds 1 to the wr number counter
firstly. While handling the second wr, the driver finds out a length error
and terminates the wr handle process, remaining the counter at 1. This
causes the driver mistakenly judges there is only 1 wr and thus enters
the direct wqe process, carrying the current length-error atomic wqe.

This patch fixes the error by adding a judgement whether the current wr
is a bad wr. If so, use the normal doorbell process but not direct wqe
despite the wr number is 1.
