Pull networking fixes from Jakub Kicinski:
"Including fixes from bpf, and bluetooth.
Not all that quiet given spring celebrations, but "current" fixes are
thinning out, which is encouraging. One outstanding regression in the
mlx5 driver when using old FW, not blocking but we're pushing for a
fix.
Current release - new code bugs:
- eth: enetc: workaround for unresponsive pMAC after receiving
express traffic
Previous releases - regressions:
- rtnetlink: restore RTM_NEW/DELLINK notification behavior, keep the
pid/seq fields 0 for backward compatibility
Previous releases - always broken:
- sctp: fix a potential overflow in sctp_ifwdtsn_skip
- mptcp:
- use mptcp_schedule_work instead of open-coding it and make the
worker check stricter, to avoid scheduling work on closed
sockets
- fix NULL pointer dereference on fastopen early fallback
- skbuff: fix memory corruption due to a race between skb coalescing
and releasing clones confusing page_pool reference counting
- bonding: fix neighbor solicitation validation on backup slaves
- bpf: tcp: use sock_gen_put instead of sock_put in bpf_iter_tcp
- bpf: arm64: fixed a BTI error on returning to patched function
- openvswitch: fix race on port output leading to inf loop
- sfp: initialize sfp->i2c_block_size at sfp allocation to avoid
returning a different errno than expected
- phy: nxp-c45-tja11xx: unregister PTP, purge queues on remove
- Bluetooth: fix printing errors if LE Connection times out
- Bluetooth: assorted UaF, deadlock and data race fixes
- eth: macb: fix memory corruption in extended buffer descriptor mode
Misc:
- adjust the XDP Rx flow hash API to also include the protocol layers
over which the hash was computed"

Update API for bpf_xdp_metadata_rx_hash() with arg for xdp rss hash type.
The veth driver currently only support XDP-hints based on SKB code path.
The SKB have lost information about the RSS hash type, by compressing
the information down to a single bitfield skb->l4_hash, that only knows
if this was a L4 hash value.
In preparation for veth, the xdp_rss_hash_type have an L4 indication
bit that allow us to return a meaningful L4 indication when working
with SKB based packets.

The RSS hash type specifies what portion of packet data NIC hardware used
when calculating RSS hash value. The RSS types are focused on Internet
traffic protocols at OSI layers L3 and L4. L2 (e.g. ARP) often get hash
value zero and no RSS type. For L3 focused on IPv4 vs. IPv6, and L4
primarily TCP vs UDP, but some hardware supports SCTP.
Hardware RSS types are differently encoded for each hardware NIC. Most
hardware represent RSS hash type as a number. Determining L3 vs L4 often
requires a mapping table as there often isn't a pattern or sorting
according to ISO layer.
The patch introduce a XDP RSS hash type (enum xdp_rss_hash_type) that
contains both BITs for the L3/L4 types, and combinations to be used by
drivers for their mapping tables. The enum xdp_rss_type_bits get exposed
to BPF via BTF, and it is up to the BPF-programmer to match using these
defines.
This proposal change the kfunc API bpf_xdp_metadata_rx_hash() adding
a pointer value argument for provide the RSS hash type.
Change signature for all xmo_rx_hash calls in drivers to make it compile.
The RSS type implementations for each driver comes as separate patches.

I got really badly confused in d443d9386472 ("fbcon: move more common
code into fb_open()") because we set the con2fb_map before the failure
points, which didn't look good.
But in trying to fix that I moved the assignment into the wrong path -
we need to do it for _all_ vc we take over, not just the first one
(which additionally requires the call to con2fb_acquire_newinfo).
I've figured this out because of a KASAN bug report, where the
fbcon_registered_fb and fbcon_display arrays went out of sync in
fbcon_mode_deleted() because the con2fb_map pointed at the old
fb_info, but the modes and everything was updated for the new one.

This is a regressoin introduced in b07db3958485 ("fbcon: Ditch error
handling for con2fb_release_oldinfo"). I failed to realize what the if
(!err) checks. The mentioned commit was dropping the
con2fb_release_oldinfo() return value but the if (!err) was also
checking whether the con2fb_acquire_newinfo() function call above
failed or not.
Fix this with an early return statement.
Note that there's still a difference compared to the orginal state of
the code, the below lines are now also skipped on error:
if (!search_fb_in_map(info_idx))
info_idx = newidx;
These are only needed when we've actually thrown out an old fb_info
from the console mappings, which only happens later on.
Also move the fbcon_add_cursor_work() call into the same if block,
it's all protected by console_lock so doesn't matter when we set up
the blinking cursor delayed work anyway. This further simplifies the
control flow and allows us to ditch the found local variable.

For quite some time we were chasing a bug which looked like a sudden
permanent failure of networking and mmc on some of our devices.
The bug was very sensitive to any software changes and even more to
any kernel debug options.
Finally we got a setup where the problem was reproducible with
CONFIG_DMA_API_DEBUG=y and it revealed the issue with the rx dma:

Lars was fast to find an explanation: according to the datasheet
bit 2 of the rx buffer descriptor entry has a different meaning in the
extended mode:
Address [2] of beginning of buffer, or
in extended buffer descriptor mode (DMA configuration register [28] = 1),
indicates a valid timestamp in the buffer descriptor entry.
The macb driver didn't mask this bit while getting an address and it
eventually caused a memory corruption and a dma failure.
The problem is resolved by explicitly clearing the problematic bit
if hw timestamping is used.

I have observed an issue where the RX direction of the LS1028A ENETC pMAC
seems unresponsive. The minimal procedure to reproduce the issue is:
1. Connect ENETC port 0 with a loopback RJ45 cable to one of the Felix
switch ports (0).
2. Bring the ports up (MAC Merge layer is not enabled on either end).
3. Send a large quantity of unidirectional (express) traffic from Felix
to ENETC. I tried altering frame size and frame count, and it doesn't
appear to be specific to either of them, but rather, to the quantity
of octets received. Lowering the frame count, the minimum quantity of
packets to reproduce relatively consistently seems to be around 37000
frames at 1514 octets (w/o FCS) each.
4. Using ethtool --set-mm, enable the pMAC in the Felix and in the ENETC
ports, in both RX and TX directions, and with verification on both
ends.
5. Wait for verification to complete on both sides.
6. Configure a traffic class as preemptible on both ends.
7. Send some packets again.
The issue is at step 5, where the verification process of ENETC ends
(meaning that Felix responds with an SMD-R and ENETC sees the response),
but the verification process of Felix never ends (it remains VERIFYING).
If step 3 is skipped or if ENETC receives less traffic than
approximately that threshold, the test runs all the way through
(verification succeeds on both ends, preemptible traffic passes fine).
If, between step 4 and 5, the step below is also introduced:
4.1. Disable and re-enable PM0_COMMAND_CONFIG bit RX_EN
then again, the sequence of steps runs all the way through, and
verification succeeds, even if there was the previous RX traffic
injected into ENETC.
Traffic sent *by* the ENETC port prior to enabling the MAC Merge layer
does not seem to influence the verification result, only received
traffic does.
The LS1028A manual does not mention any relationship between
PM0_COMMAND_CONFIG and MMCSR, and the hardware people don't seem to
know for now either.
The bit that is toggled to work around the issue is also toggled
by enetc_mac_enable(), called from phylink's mac_link_down() and
mac_link_up() methods - which is how the workaround was found:
verification would work after a link down/up.

Remove an inability of bnxt_en driver to set eswitch to switchdev
mode without existing VFs by:
1. Allow to set switchdev mode in bnxt_dl_eswitch_mode_set() so
representors are created only when num_vfs > 0 otherwise just
set bp->eswitch_mode
2. Do not automatically change bp->eswitch_mode during
bnxt_vf_reps_create() and bnxt_vf_reps_destroy() calls so
the eswitch mode is managed only by an user by devlink.
Just set temporarily bp->eswitch_mode to legacy to avoid
re-opening of representors during destroy.
3. Create representors in bnxt_sriov_enable() if current eswitch
mode is switchdev one
Tested by this sequence:
1. Set PF interface up
2. Set PF's eswitch mode to switchdev
3. Created N VFs
4. Checked that N representors were created
5. Set eswitch mode to legacy
6. Checked that representors were deleted
7. Set eswitch mode back to switchdev
8. Checked that representors exist again for VFs
9. Deleted all VFs
10. Checked that all representors were deleted as well
11. Checked that current eswitch mode is still switchdev

The driver was incorrectly overwriting the cyclecounter bitmask,

This isn't causing any issues, but it's wrong. Fix this by not

Luckily, this seems to cause no issues, which is why this change
doesn't have a fixes tag and isn't being sent to net. However, if
any transformations from time->cycles are needed in the future,

The usual devm_regulator_get() call already handles "optional"
regulators by returning a valid dummy and printing a warning
that the dummy regulator should be described properly. This
code open coded the same behaviour, but masked any errors that
are not -EPROBE_DEFER and is quite noisy.
This change effectively unmasks and propagates regulators errors
not involving -ENODEV, downgrades the error print to warning level
if no regulator is specified and captures the probe defer message
for /sys/kernel/debug/devices_deferred.

iavf: fix racing in VLANs
Ahmed Zaki says:
This patchset mainly fixes a racing issue in the iavf where the number of
VLANs in the vlan_filter_list might be more than the PF limit. To fix that,
we get rid of the cvlans and svlans bitmaps and keep all the required info
in the list.
The second patch adds two new states that are needed so that we keep the
VLAN info while the interface goes DOWN:
-- DISABLE (notify PF, but keep the filter in the list)
-- INACTIVE (dev is DOWN, filter is removed from PF)
Finally, the current code keeps each state in a separate bit field, which
is error prone. The first patch refactors that by replacing all bits with
a single enum. The changes are minimal where each bit change is replaced
with the new state value.

In STEv1 counter action can be set either by filling counter ID on STE, in
which case it is executed before other actions on this STE, or as a single
action, in which case it is executed in accordance with the actions order.
FW steering on STEv1 devices implements counter as counter ID on STE, and
this counter is set on the last STE.
Fix SMFS to be consistent with this behaviour - move TX counter to the
last STE, this way the counter will include all actions of the previous STEs
that might have changed packet headers length, e.g. encap, vlan push, etc.
