Veerasenareddy Burru says:

====================
octeon_ep: deferred probe and mailbox

Implement Deferred probe, mailbox enhancements and heartbeat monitor.

v4 -> v5:
   - addressed review comments
     https://lore.kernel.org/all/20230323104703.GD36557@unreal/
     replaced atomic_inc() + atomic_read() with atomic_inc_return().

v3 -> v4:
   - addressed review comments on v3
     https://lore.kernel.org/all/20230214051422.13705-1-vburru@marvell.com/
   - 0004-xxx.patch v3 is split into 0004-xxx.patch and 0005-xxx.patch
     in v4.
   - API changes to accept function ID are moved to 0005-xxx.patch.
   - fixed rct violations.
   - reverted newly added changes that do not yet have use cases.

v2 -> v3:
   - removed SRIOV VF support changes from v2, as new drivers which use
     ndo_get_vf_xxx() and ndo_set_vf_xxx() are not accepted.
     https://lore.kernel.org/all/20221207200204.6819575a@kernel.org/

     Will implement VF representors and submit again.
   - 0007-xxx.patch and 0008-xxx.patch from v2 are removed and
     0009-xxx.patch in v2 is now 0007-xxx.patch in v3.
   - accordingly, changed title for cover letter.

v1 -> v2:
   - remove separate workqueue task to wait for firmware ready.
     instead defer probe when firmware is not ready.
     Reported-by: Leon Romanovsky <leon@kernel.org>
   - This change has resulted in update of 0001-xxx.patch and
     all other patches in the patchset.

5cb96c29aa octeon_ep: add heartbeat monitor
Monitor periodic heartbeat messages from device firmware.
Presence of heartbeat indicates the device is active and running.
If the heartbeat is missed for configured interval indicates
firmware has crashed and device is unusable; in this case, PF driver
stops and uninitialize the device.

fbf8ba5666 Merge branch 'bcm53134-support'
Álvaro Fernández Rojas says:

====================
net: dsa: b53: mdio: add support for BCM53134

This is based on the initial work from Paul Geurts that was sent to the
incorrect linux development lists and recipients.
I've modified it by removing BCM53134_DEVICE_ID from is531x5() and therefore
adding is53134() where needed.
I also added a separate RGMII handling block for is53134() since according to
Paul, BCM53134 doesn't support RGMII_CTRL_TIMING_SEL as opposed to is531x5().

bc77f7318d tools: ynl: add the Python requirements.txt file
It is a good practice to state explicitly which are the required Python
packages needed in a particular project to run it. The most commonly
used way is to store them in the `requirements.txt` file*.

*URL: https://pip.pypa.io/en/stable/reference/requirements-file-format/

Currently user needs to figure out himself that Python needs `PyYAML`
and `jsonschema` (and theirs requirements) packages to use the tool.
Add the `requirements.txt` for user convenience.

How to use it:
1) (optional) Create and activate empty virtual environment:
  python3.X -m venv venv3X
  source ./venv3X/bin/activate
2) Install all the required packages:
  pip install -r requirements.txt
    or
  python -m pip install -r requirements.txt
3) Run the script!

The `requirements.txt` file was tested for:
* Python 3.6
* Python 3.8
* Python 3.10

When the PHY library calls phy_error() something bad has happened, and
we halt the PHY state machine. Calling phy_error() from the main state
machine however is not precise enough to know whether the issue is

2df9bf4d04 ipv6: prevent router_solicitations for team port
The issue fixed for bonding in commit c2edacf80e ("bonding / ipv6: no
addrconf for slaves separately from master") also exists in team driver.
However, we can't just disable ipv6 addrconf for team ports, as 'teamd'
will need it when nsns_ping watch is used in the user space.

Instead of preventing ipv6 addrconf, this patch only prevents RS packets
for team ports, as it did in commit b52e1cce31 ("ipv6: Don't send rs
packets to the interface of ARPHRD_TUNNEL").

Note that we do not prevent DAD packets, to avoid the changes getting
intricate / hacky. Also, usually sysctl dad_transmits is set to 1 and
only 1 DAD packet will be sent, and by now no libteam user complains
about DAD packets on team ports, unlike RS packets.

Florian Westphal says:

====================
netfilter updates for net-next

This pull request contains changes for the *net-next* tree.

1. Change IPv6 stack to keep conntrack references until ipsec policy
   checks are done, like ipv4, from Madhu Koriginja.
   This update was missed when IPv6 NAT support was added 10 years ago.

2. get rid of old 'compat' structure layout in nf_nat_redirect
   core and move the conversion to the only user that needs the
   old layout for abi reasons. From Jeremy Sowden.

3. Compact some common code paths in nft_redir, also from Jeremy.

4. Time to remove the 'default y' knob so iptables 32bit compat interface
   isn't compiled in by default anymore, from myself.

5. Move ip(6)tables builtin icmp matches to the udptcp one.
   This has the advantage that icmp/icmpv6 match doesn't load the
   iptables/ip6tables modules anymore when iptables-nft is used.
   Also from myself.

* 'main' of ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/netfilter/nf-next:
  netfilter: keep conntrack reference until IPsecv6 policy checks are done
  xtables: move icmp/icmpv6 logic to xt_tcpudp
  netfilter: xtables: disable 32bit compat interface by default
  netfilter: nft_masq: deduplicate eval call-backs
  netfilter: nft_redir: use `struct nf_nat_range2` throughout and deduplicate eval call-backs

4691720f50 bnx2: remove deadcode in bnx2_init_cpus()
The load_cpu_fw function has no error return code
and always returns zero. Checking the value returned by
this function does not make sense.
Now checking the value of the return value is misleading when reading
the code. Path with error handling was deleted in 57579f7629
("bnx2: Use request_firmware()").
As a result, bnx2_init_cpus() will also return only zero
Therefore, it will be safe to change the type of functions
to void and remove checking to improving readability.

8da3a5598f ynl: allow to encode u8 attr
Playing with dpll netlink, I came across following issue:
$ sudo ./tools/net/ynl/cli.py --spec Documentation/netlink/specs/dpll.yaml --do pin-set --json '{"id": 0, "pin-idx": 1, "pin-state": 1}'
Traceback (most recent call last):
  File "tools/net/ynl/cli.py", line 52, in <module>
    main()
  File "tools/net/ynl/cli.py", line 40, in main
    reply = ynl.do(args.do, attrs)
  File "tools/net/ynl/lib/ynl.py", line 520, in do

    raise Exception(f'Unknown type at {space} {name} {value} {attr["type"]}')
Exception: Unknown type at dpll pin-state 1 u8

I'm not that familiar with ynl code, but from a quick peek, I suspect
that couple other types are missing for both encoding and decoding.
Ignoring those here as I'm scratching my local itch only.

Fix the issue by adding u8 attr packing.

bce5640520 Bluetooth: HCI: Fix global-out-of-bounds
To loop a variable-length array, hci_init_stage_sync(stage) considers
that stage[i] is valid as long as stage[i-1].func is valid.
Thus, the last element of stage[].func should be intentionally invalid
as hci_init0[], le_init2[], and others did.
However, amp_init1[] and amp_init2[] have no invalid element, letting
hci_init_stage_sync() keep accessing amp_init1[] over its valid range.
This patch fixes this by adding {} in the last of amp_init1[] and
amp_init2[].

5d44ab9e20 Bluetooth: btqcomsmd: Fix command timeout after setting BD address
On most devices using the btqcomsmd driver (e.g. the DragonBoard 410c
and other devices based on the Qualcomm MSM8916/MSM8909/... SoCs)
the Bluetooth firmware seems to become unresponsive for a while after
setting the BD address. On recent kernel versions (at least 5.17+)
this often causes timeouts for subsequent commands, e.g. the HCI reset
sent by the Bluetooth core during initialization:

    Bluetooth: hci0: Opcode 0x c03 failed: -110

Unfortunately this behavior does not seem to be documented anywhere.
Experimentation suggests that the minimum necessary delay to avoid
the problem is ~150us. However, to be sure add a sleep for > 1ms
in case it is a bit longer on other firmware versions.

Older kernel versions are likely also affected, although perhaps with
slightly different errors or less probability. Side effects can easily
hide the issue in most cases, e.g. unrelated incoming interrupts that
cause the necessary delay.

260595b439 Reinstate "GFS2: free disk inode which is deleted by remote node -V2"
It turns out that reverting commit 970343cd49 ("GFS2: free disk inode
which is deleted by remote node -V2") causes a regression related to
evicting inodes that were unlinked on a different cluster node.

We could also have simply added a call to d_mark_dontcache() to function
gfs2_try_evict(), but the original pre-revert code is better tested and
proven.

This reverts commit 445cb1277e.
