fe03fd373c igc: Clean the TX buffer and TX descriptor ring
[ Upstream commit e43516f597 ]

There could be a race condition during link down where interrupt
being generated and igc_clean_tx_irq() been called to perform the
TX completion. Properly clear the TX buffer/descriptor ring and
disable the TX Queue ring in igc_free_tx_resources() to avoid that.

981e78781a ipvlan: fix bound dev checking for IPv6 l3s mode
[ Upstream commit ce57adc222 ]

The commit 59a0b022aa ("ipvlan: Make skb->skb_iif track skb->dev for l3s
mode") fixed ipvlan bonded dev checking by updating skb skb_iif. This fix
works for IPv4, as in raw_v4_input() the dif is from inet_iif(skb), which
is skb->skb_iif when there is no route.

But for IPv6, the fix is not enough, because in ipv6_raw_deliver() ->
raw_v6_match(), the dif is inet6_iif(skb), which is returns IP6CB(skb)->iif
instead of skb->skb_iif if it's not a l3_slave. To fix the IPv6 part
issue. Let's set IP6CB(skb)->iif to correct ifindex.

BTW, ipvlan handles NS/NA specifically. Since it works fine, I will not
reset IP6CB(skb)->iif when addr->atype is IPVL_ICMPV6.

4dd914b9e2 iavf: remove mask from iavf_irq_enable_queues()
[ Upstream commit c37cf54c12 ]

Enable more than 32 IRQs by removing the u32 bit mask in
iavf_irq_enable_queues(). There is no need for the mask as there are no
callers that select individual IRQs through the bitmask. Also, if the PF
allocates more than 32 IRQs, this mask will prevent us from using all of
them.

Modify the comment in iavf_register.h to show that the maximum number
allowed for the IRQ index is 63 as per the iAVF standard 1.0 [1].

471a4c08e3 net: enetc: correct the indexes of highest and 2nd highest TCs
[ Upstream commit 21225873be ]

For ENETC hardware, the TCs are numbered from 0 to N-1, where N
is the number of TCs. Numerically higher TC has higher priority.
It's obvious that the highest priority TC index should be N-1 and
the 2nd highest priority TC index should be N-2.

However, the previous logic uses netdev_get_prio_tc_map() to get
the indexes of highest priority and 2nd highest priority TCs, it
does not make sense and is incorrect to give a "tc" argument to
netdev_get_prio_tc_map(). So the driver may get the wrong indexes
of the two highest priotiry TCs which would lead to failed to set
the CBS for the two highest priotiry TCs.

e.g.
$ tc qdisc add dev eno0 parent root handle 100: mqprio num_tc 6 \
	map 0 0 1 1 2 3 4 5 queues 1@0 1@1 1@2 1@3 2@4 2@6 hw 1
$ tc qdisc replace dev eno0 parent 100:6 cbs idleslope 100000 \
	sendslope -900000 hicredit 12 locredit -113 offload 1
$ Error: Specified device failed to setup cbs hardware offload.
  ^^^^^

In this example, the previous logic deems the indexes of the two
highest priotiry TCs should be 3 and 2. Actually, the indexes are
5 and 4, because the number of TCs is 6. So it would be failed to
configure the CBS for the two highest priority TCs.

aedad6c7fb bnxt_en: Implement .set_port / .unset_port UDP tunnel callbacks
[ Upstream commit 1eb4ef1259 ]

As per the new udp tunnel framework, drivers which need to know the
details of a port entry (i.e. port type) when it gets deleted should
use the .set_port / .unset_port callbacks.

Implementing the current .udp_tunnel_sync callback would mean that the
deleted tunnel port entry would be all zeros.  This used to work on
older firmware because it would not check the input when deleting a
tunnel port.  With newer firmware, the delete will now fail and
subsequent tunnel port allocation will fail as a result.

a94401de2b bnxt_en: Query default VLAN before VNIC setup on a VF
[ Upstream commit 1a9e4f501b ]

We need to call bnxt_hwrm_func_qcfg() on a VF to query the default
VLAN that may be setup by the PF.  If a default VLAN is enabled,
the VF cannot support VLAN acceleration on the receive side and
the VNIC must be setup to strip out the default VLAN tag.  If a
default VLAN is not enabled, the VF can support VLAN acceleration
on the receive side.  The VNIC should be set up to strip or not
strip the VLAN based on the RX VLAN acceleration setting.

Without this call to determine the default VLAN before calling
bnxt_setup_vnic(), the VNIC may not be set up correctly.  For
example, bnxt_setup_vnic() may set up to strip the VLAN tag based
on stale default VLAN information.  If RX VLAN acceleration is
not enabled, the VLAN tag will be incorrectly stripped and the
RX data path will not work correctly.

The rx_bytes of struct net_device_stats should count the length of
ethernet frames excluding the FCS. However, there are two problems
with the rx_bytes statistics of the current enetc driver. one is
that the length of VLAN header is not counted if the VLAN extraction
feature is enabled. The other is that the length of L2 header is not
counted, because eth_type_trans() is invoked before updating rx_bytes
which will subtract the length of L2 header from skb->len.
BTW, the rx_bytes statistics of XDP path also have similar problem,
I will fix it in another patch.

43124187fe ath6kl: Use struct_group() to avoid size-mismatched casting
commit e3128a9d48 upstream.

In builds with -Warray-bounds, casts from smaller objects to larger
objects will produce warnings. These can be overly conservative, but since
-Warray-bounds has been finding legitimate bugs, it is desirable to turn
it on globally. Instead of casting a u32 to a larger object, redefine
the u32 portion of the header to a separate struct that can be used for
both u32 operations and the distinct header fields. Silences this warning:

drivers/net/wireless/ath/ath6kl/htc_mbox.c: In function 'htc_wait_for_ctrl_msg':
drivers/net/wireless/ath/ath6kl/htc_mbox.c:2275:20: error: array subscript 'struct htc_frame_hdr[0]' is partly outside array bounds of 'u32[1]' {aka 'unsigned int[1]'} [-Werror=array-bounds]

82f505878f wifi: b43: fix incorrect __packed annotation
[ Upstream commit 212457ccbd ]

clang warns about an unpacked structure inside of a packed one:

drivers/net/wireless/broadcom/b43/b43.h:654:4: error: field data within 'struct b43_iv' is less aligned than 'union (unnamed union at /home/arnd/arm-soc/drivers/net/wireless/broadcom/b43/b43.h:651:2)' and is usually due to 'struct b43_iv' being packed, which can lead to unaligned accesses [-Werror,-Wunaligned-access]

The problem here is that the anonymous union has the default alignment
from its members, apparently because the original author mixed up the
placement of the __packed attribute by placing it next to the struct
member rather than the union definition. As the struct itself is
also marked as __packed, there is no need to mark its members, so just
move the annotation to the inner type instead.

As Michael noted, the same problem is present in b43legacy, so
change both at the same time.

b2f00acd53 wifi: rtl8xxxu: fix authentication timeout due to incorrect RCR value
[ Upstream commit 20429444e6 ]

When using rtl8192cu with rtl8xxxu driver to connect wifi, there is a
probability of failure, which shows "authentication with ... timed out".
Through debugging, it was found that the RCR register has been inexplicably
modified to an incorrect value, resulting in the nic not being able to
receive authenticated frames.

To fix this problem, add regrcr in rtl8xxxu_priv struct, and store
the RCR value every time the register is written, and use it the next
time the register need to be modified.

A switch held in reset by default needs to wait longer until we can

An issue was observed when testing on the Marvell 88E6393X (Link Street).

8d9d0bfd4c net/mlx5e: Don't attach netdev profile while handling internal error
[ Upstream commit bdf274750f ]

As part of switchdev mode disablement, driver changes port netdevice
profile from uplink to nic. If this process is triggered by health
recovery flow (PCI reset, for ex.) profile attach would fail because all
fw commands aborted when internal error flag is set. As a result, nic
netdevice profile is not attached and driver fails to rollback to uplink
profile, which leave driver in broken state and cause crash later.

To handle broken state do netdevice profile initialization only instead
of full attachment and release mdev resources on driver suspend as
expected. Actual netdevice attachment is done during driver load.

Bonding send_peer_notif was defined as u8. Since commit 07a4ddec3c

the bond->send_peer_notif will be num_peer_notif multiplied by
peer_notif_delay, which is u8 * u32. This would cause the send_peer_notif
overflow easily. e.g.

  ip link add bond0 type bond mode 1 miimon 100 num_grat_arp 30 peer_notify_delay 1000

5b925b48be net: dsa: mt7530: fix network connectivity with multiple CPU ports
[ Upstream commit 120a56b01b ]

On mt753x_cpu_port_enable() there's code that enables flooding for the CPU
port only. Since mt753x_cpu_port_enable() runs twice when both CPU ports
are enabled, port 6 becomes the only port to forward the frames to. But
port 5 is the active port, so no frames received from the user ports will
be forwarded to port 5 which breaks network connectivity.

Every bit of the BC_FFP, UNM_FFP, and UNU_FFP bits represents a port. Fix
this issue by setting the bit that corresponds to the CPU port without
overwriting the other bits.

Clear the bits beforehand only for the MT7531 switch. According to the
documents MT7621 Giga Switch Programming Guide v0.3 and MT7531 Reference
Manual for Development Board v1.0, after reset, the BC_FFP, UNM_FFP, and
UNU_FFP bits are set to 1 for MT7531, 0 for MT7530.

The commit 5e5502e012 ("net: dsa: mt7530: fix roaming from DSA user
ports") silently changed the method to set the bits on the MT7530_MFC.
Instead of clearing the relevant bits before mt7530_cpu_port_enable()
which runs under a for loop, the commit started doing it on
mt7530_cpu_port_enable().

Back then, this didn't really matter as only a single CPU port could be
used since the CPU port number was hardcoded. The driver was later changed
with commit 1f9a6abecf ("net: dsa: mt7530: get cpu-port via dp->cpu_dp
instead of constant") to retrieve the CPU port via dp->cpu_dp. With that,
this silent change became an issue for when using multiple CPU ports.

69966bce28 net/mlx5e: Fix deadlock in tc route query code
[ Upstream commit 691c041bf2 ]

Cited commit causes ABBA deadlock[0] when peer flows are created while
holding the devcom rw semaphore. Due to peer flows offload implementation
the lock is taken much higher up the call chain and there is no obvious way
to easily fix the deadlock. Instead, since tc route query code needs the
peer eswitch structure only to perform a lookup in xarray and doesn't
perform any sleeping operations with it, refactor the code for lockless
execution in following ways:

- RCUify the devcom 'data' pointer. When resetting the pointer
synchronously wait for RCU grace period before returning. This is fine
since devcom is currently only used for synchronization of
pairing/unpairing of eswitches which is rare and already expensive as-is.

- Wrap all usages of 'paired' boolean in {READ|WRITE}_ONCE(). The flag has
already been used in some unlocked contexts without proper
annotations (e.g. users of mlx5_devcom_is_paired() function), but it wasn't
an issue since all relevant code paths checked it again after obtaining the
devcom semaphore. Now it is also used by mlx5_devcom_get_peer_data_rcu() as
"best effort" check to return NULL when devcom is being unpaired. Note that
while RCU read lock doesn't prevent the unpaired flag from being changed
concurrently it still guarantees that reader can continue to use 'data'.

- Refactor mlx5e_tc_query_route_vport() function to use new
mlx5_devcom_get_peer_data_rcu() API which fixes the deadlock.

commit af87194352 upstream.

In case devcom allocation is failed, mlx5 is always freeing the priv.
However, this priv might have been allocated by a different thread,
and freeing it might lead to use-after-free bugs.
Fix it by freeing the priv only in case it was allocated by the
running thread.

e8a974bbf4 net/mlx5: DR, Check force-loopback RC QP capability independently from RoCE
commit c7dd225bc2 upstream.

SW Steering uses RC QP for writing STEs to ICM. This writingis done in LB
(loopback), and FL (force-loopback) QP is preferred for performance. FL is
available when RoCE is enabled or disabled based on RoCE caps.
This patch adds reading of FL capability from HCA caps in addition to the
existing reading from RoCE caps, thus fixing the case where we didn't
have loopback enabled when RoCE was disabled.

5e0cc0d502 net/mlx5: DR, Fix crc32 calculation to work on big-endian (BE) CPUs
commit 1e5daf5565 upstream.

When calculating crc for hash index we use the function crc32 that
calculates for little-endian (LE) arch.
Then we convert it to network endianness using htonl(), but it's wrong
to do the conversion in BE archs since the crc32 value is already LE.

The solution is to switch the bytes from the crc result for all types
of arc.

792a8233fc net/mlx5e: do as little as possible in napi poll when budget is 0
commit afbed3f748 upstream.

NAPI gets called with budget of 0 from netpoll, which has interrupts
disabled. We should try to free some space on Tx rings and nothing
else.

Specifically do not try to handle XDP TX or try to refill Rx buffers -
we can't use the page pool from IRQ context. Don't check if IRQs moved,
either, that makes no sense in netpoll. Netpoll calls _all_ the rings
from whatever CPU it happens to be invoked on.

In general do as little as possible, the work quickly adds up when
there's tens of rings to poll.

The immediate stack trace I was seeing is:

    __do_softirq+0xd1/0x2c0
    __local_bh_enable_ip+0xc7/0x120
    </IRQ>

AFAIU page pool takes a BH lock, releases it and since BH is now
enabled tries to run softirqs.
