[ Upstream commit a129b41fe0a8b4da828c46b10f5244ca07a3fec3 ]
This reverts commit da9ef50f545f86ffe6ff786174d26500c4db737a.
This fixes a regression in which the link would come up, but no
communication was possible.
The reverted commit was also removing a comment about
DP83867_PHYCR_FORCE_LINK_GOOD, this is not added back in this commits
since it seems that this is unrelated to the original code change.

already has a workaround for this so do the workaround for this NIC too.

that the synchronization is never finished and schedule()

[ Upstream commit 4aaf2c52834b7f95acdf9fb0211a1b60adbf421b ]
When running workloads heavy unbalanced towards TX (high TX, low RX
traffic), sfc driver can retain the CPU during too long times. Although
in many cases this is not enough to be visible, it can affect
performance and system responsiveness.
A way to reproduce it is to use a debug kernel and run some parallel
netperf TX tests. In some systems, this will lead to this message being
logged:
kernel:watchdog: BUG: soft lockup - CPU#12 stuck for 22s!
The reason is that sfc driver doesn't account any NAPI budget for the TX
completion events work. With high-TX/low-RX traffic, this makes that the
CPU is held for long time for NAPI poll.
Documentations says "drivers can process completions for any number of Tx
packets but should only process up to budget number of Rx packets".
However, many drivers do limit the amount of TX completions that they
process in a single NAPI poll.
In the same way, this patch adds a limit for the TX work in sfc. With
the patch applied, the watchdog warning never appears.
Tested with netperf in different combinations: single process / parallel
processes, TCP / UDP and different sizes of UDP messages. Repeated the
tests before and after the patch, without any noticeable difference in
network or CPU performance.

In systems without MSI-X capabilities, xdp_txq_queues_mode is calculated
in efx_allocate_msix_channels, but when enabling MSI-X fails, it was not
changed to a proper default value. This was leading to the driver
thinking that it has dedicated XDP queues, when it didn't.
Fix it by setting xdp_txq_queues_mode to the correct value if the driver
fallbacks to MSI or legacy IRQ mode. The correct value is
EFX_XDP_TX_QUEUES_BORROWED because there are no XDP dedicated queues.
The issue can be easily visible if the kernel is started with pci=nomsi,

because apparently, a multiplication between two 32-bit factors is

The commit 59a0b022aa24 ("ipvlan: Make skb->skb_iif track skb->dev for l3s

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.

The cited commit aimed to ensure that Virtual Functions (VFs) assign a
queue affinity to a Queue Pair (QP) to distribute traffic when
the LAG master creates a hardware LAG. If the affinity was set while
the hardware was not in LAG, the firmware would ignore the affinity value.
However, this commit unintentionally assigned an affinity to QPs on the LAG
master's VPORT even if the RDMA device was not marked as LAG-enabled.
In most cases, this was not an issue because when the hardware entered
hardware LAG configuration, the RDMA device of the LAG master would be
destroyed and a new one would be created, marked as LAG-enabled.
The problem arises when a user configures Equal-Cost Multipath (ECMP).
In ECMP mode, traffic can be directed to different physical ports based on
the queue affinity, which is intended for use by VPORTS other than the
E-Switch manager. ECMP mode is supported only if both E-Switch managers are
in switchdev mode and the appropriate route is configured via IP. In this
configuration, the RDMA device is not destroyed, and we retain the RDMA
device that is not marked as LAG-enabled.
To ensure correct behavior, Send Queues (SQs) opened by the E-Switch
manager through verbs should be assigned strict affinity. This means they
will only be able to communicate through the native physical port
associated with the E-Switch manager. This will prevent the firmware from
assigning affinity and will not allow the SQs to be remapped in case of
failover.

that are different with newer i210. The EXTTS capture value in
AUXTSMPx should be converted from raw circle counter value to

This issue can be reproduced on i350 nics, connecting an 1PPS

extts is not correctly converted.
The i350/i354/82580's SYSTIM and other timestamp registers are
40bit counters, presenting time range of 2^40 ns, that means these
registers overflows every about 1099s. This causes all these regs
can't be used directly in contrast to the newer i210/i211s.
The igb driver needs to convert these raw register values to
valid time stamp format by using kernel timecounter apis for i350s
families. Here the igb_extts() just forgot to do the convert.

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.

This driver relies on IEEE80211_CONF_PS of hw->conf.flags to turn off PS or
turn on dynamic PS controlled by driver and firmware. Though this would be
incorrect, it did work before because the flag is always recalculated until
the commit 28977e790b5d ("wifi: mac80211: skip powersave recalc if driver SUPPORTS_DYNAMIC_PS")
is introduced by kernel 5.20 to skip to recalculate IEEE80211_CONF_PS
of hw->conf.flags if driver sets SUPPORTS_DYNAMIC_PS.
Correct this by doing recalculation while BSS_CHANGED_PS is changed and
interface is added or removed. It is allowed to enter PS only if single
one station vif is working. Without this fix, driver doesn't enter PS
anymore that causes higher power consumption.

commit 7a4615b9a9da5225b22b36a20508555dd133ac24 upstream.
kmemdup() at line 2735 is not duplicating enough memory for
notif->tid_tear_down and notif->station_id. As it only duplicates
612 bytes: up to offsetofend(struct iwl_wowlan_info_notif,
received_beacons), this is the range of [0, 612) bytes.
2735 notif = kmemdup(notif_v1,
2736 offsetofend(struct iwl_wowlan_info_notif,
2737 received_beacons),
2738 GFP_ATOMIC);
which evidently does not cover bytes 612 and 613 for members
tid_tear_down and station_id in struct iwl_wowlan_info_notif.
See below:
$ pahole -C iwl_wowlan_info_notif drivers/net/wireless/intel/iwlwifi/mvm/d3.o
struct iwl_wowlan_info_notif {
struct iwl_wowlan_gtk_status_v3 gtk[2]; /* 0 488 */
/* --- cacheline 7 boundary (448 bytes) was 40 bytes ago --- */
struct iwl_wowlan_igtk_status igtk[2]; /* 488 80 */
/* --- cacheline 8 boundary (512 bytes) was 56 bytes ago --- */
__le64 replay_ctr; /* 568 8 */
/* --- cacheline 9 boundary (576 bytes) --- */
__le16 pattern_number; /* 576 2 */
__le16 reserved1; /* 578 2 */
__le16 qos_seq_ctr[8]; /* 580 16 */
__le32 wakeup_reasons; /* 596 4 */
__le32 num_of_gtk_rekeys; /* 600 4 */
__le32 transmitted_ndps; /* 604 4 */
__le32 received_beacons; /* 608 4 */
u8 tid_tear_down; /* 612 1 */
u8 station_id; /* 613 1 */
u8 reserved2[2]; /* 614 2 */
/* size: 616, cachelines: 10, members: 13 */
/* last cacheline: 40 bytes */
};
Therefore, when the following assignments take place, actually no memory
has been allocated for those objects:
2743 notif->tid_tear_down = notif_v1->tid_tear_down;
2744 notif->station_id = notif_v1->station_id;
Fix this by allocating space for the whole notif object and zero out the
remaining space in memory after member station_id.
This also fixes the following -Warray-bounds issues:

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.

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.

commit 04361b8bb81819efb68bf39c276025e2250ac537 upstream.
Andrew reports that the SFF modules on one of the ZII platforms do not
indicate link up due to the SFP code believing that LOS indicating that
there is no signal being received from the remote end, but in fact the
LOS signal is showing that there is signal.
What makes SFF modules different from SFPs is they typically have an
inverted LOS, which uncovered this issue. When we read the hardware
state, we mask it with state_hw_mask so we ignore anything we're not
interested in. However, we don't re-read when state_hw_mask changes,
leading to sfp->state being stale.
Arrange for a software poll of the module state after we have parsed
the EEPROM in sfp_sm_mod_probe() and updated state_*_mask. This will
generate any necessary events for signal changes for the state
machine as well as updating sfp->state.

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.
