5cf5337ef7 net/mlx5: Properly link new fs rules into the tree
[ Upstream commit 7c6782ad49 ]

Previously, add_rule_fg would only add newly created rules from the
handle into the tree when they had a refcount of 1. On the other hand,
create_flow_handle tries hard to find and reference already existing
identical rules instead of creating new ones.

These two behaviors can result in a situation where create_flow_handle
1) creates a new rule and references it, then
2) in a subsequent step during the same handle creation references it
   again,
resulting in a rule with a refcount of 2 that is not linked into the
tree, will have a NULL parent and root and will result in a crash when
the flow group is deleted because del_sw_hw_rule, invoked on rule
deletion, assumes node->parent is != NULL.

This happened in the wild, due to another bug related to incorrect
handling of duplicate pkt_reformat ids, which lead to the code in
create_flow_handle incorrectly referencing a just-added rule in the same
flow handle, resulting in the problem described above. Full details are
at [1].

This patch changes add_rule_fg to add new rules without parents into
the tree, properly initializing them and avoiding the crash. This makes
it more consistent with how rules are added to an FTE in
create_flow_handle.

cbe5852d3d net/mlx5: offset comp irq index in name by one
[ Upstream commit 9f7e8fbb91 ]

The mlx5 comp irq name scheme is changed a little bit between
commit 3663ad34bc ("net/mlx5: Shift control IRQ to the last index")
and commit 3354822cde ("net/mlx5: Use dynamic msix vectors allocation").
The index in the comp irq name used to start from 0 but now it starts
from 1. There is nothing critical here, but it's harmless to change
back to the old behavior, a.k.a starting from 0.

8c91c60858 net/mlx5: Register devlink first under devlink lock
[ Upstream commit c6e77aa9dd ]

In case device is having a non fatal FW error during probe, the
driver will report the error to user via devlink. This will trigger
a WARN_ON, since mlx5 is calling devlink_register() last.
In order to avoid the WARN_ON[1], change mlx5 to invoke devl_register()
first under devlink lock.

When PF/VF teardown is called the driver sets the flag
MLX5_BREAK_FW_WAIT to stop waiting for FW loading and initializing. Same

cba376eb03 net: ks8851: Handle softirqs at the end of IRQ thread to fix hang
[ Upstream commit be0384bf59 ]

The ks8851_irq() thread may call ks8851_rx_pkts() in case there are
any packets in the MAC FIFO, which calls netif_rx(). This netif_rx()
implementation is guarded by local_bh_disable() and local_bh_enable().
The local_bh_enable() may call do_softirq() to run softirqs in case
any are pending. One of the softirqs is net_rx_action, which ultimately
reaches the driver .start_xmit callback. If that happens, the system
hangs. The entire call chain is below:

ks8851_start_xmit_par from netdev_start_xmit
netdev_start_xmit from dev_hard_start_xmit
dev_hard_start_xmit from sch_direct_xmit
sch_direct_xmit from __dev_queue_xmit
__dev_queue_xmit from __neigh_update
__neigh_update from neigh_update
neigh_update from arp_process.constprop.0
arp_process.constprop.0 from __netif_receive_skb_one_core
__netif_receive_skb_one_core from process_backlog
process_backlog from __napi_poll.constprop.0
__napi_poll.constprop.0 from net_rx_action
net_rx_action from __do_softirq
__do_softirq from call_with_stack
call_with_stack from do_softirq
do_softirq from __local_bh_enable_ip
__local_bh_enable_ip from netif_rx
netif_rx from ks8851_irq
ks8851_irq from irq_thread_fn
irq_thread_fn from irq_thread
irq_thread from kthread
kthread from ret_from_fork

The hang happens because ks8851_irq() first locks a spinlock in
ks8851_par.c ks8851_lock_par() spin_lock_irqsave(&ksp->lock, ...)
and with that spinlock locked, calls netif_rx(). Once the execution
reaches ks8851_start_xmit_par(), it calls ks8851_lock_par() again
which attempts to claim the already locked spinlock again, and the
hang happens.

Move the do_softirq() call outside of the spinlock protected section
of ks8851_irq() by disabling BHs around the entire spinlock protected
section of ks8851_irq() handler. Place local_bh_enable() outside of
the spinlock protected section, so that it can trigger do_softirq()
without the ks8851_par.c ks8851_lock_par() spinlock being held, and
safely call ks8851_start_xmit_par() without attempting to lock the
already locked spinlock.

Since ks8851_irq() is protected by local_bh_disable()/local_bh_enable()
now, replace netif_rx() with __netif_rx() which is not duplicating the
local_bh_disable()/local_bh_enable() calls.

Otherwise, we may not accept any PTP TX timestamps after
recovery.

190d9efa57 geneve: fix header validation in geneve[6]_xmit_skb
[ Upstream commit d8a6213d70 ]

syzbot is able to trigger an uninit-value in geneve_xmit() [1]

Problem : While most ip tunnel helpers (like ip_tunnel_get_dsfield())
uses skb_protocol(skb, true), pskb_inet_may_pull() is only using
skb->protocol.

If anything else than ETH_P_IPV6 or ETH_P_IP is found in skb->protocol,
pskb_inet_may_pull() does nothing at all.

If a vlan tag was provided by the caller (af_packet in the syzbot case),
the network header might not point to the correct location, and skb
linear part could be smaller than expected.

Add skb_vlan_inet_prepare() to perform a complete mac validation.

Use this in geneve for the moment, I suspect we need to adopt this
more broadly.

v4 - Jakub reported v3 broke l2_tos_ttl_inherit.sh selftest
   - Only call __vlan_get_protocol() for vlan types.

c926393dc3 ice: use relative VSI index for VFs instead of PF VSI number
[ Upstream commit 11fbb1bfb5 ]

When initializing over virtchnl, the PF is required to pass a VSI ID to the
VF as part of its capabilities exchange. The VF driver reports this value
back to the PF in a variety of commands. The PF driver validates that this
value matches the value it sent to the VF.

Some hardware families such as the E700 series could use this value when
reading RSS registers or communicating directly with firmware over the
Admin Queue.

However, E800 series hardware does not support any of these interfaces and
the VF's only use for this value is to report it back to the PF. Thus,
there is no requirement that this value be an actual VSI ID value of any
kind.

The PF driver already does not trust that the VF sends it a real VSI ID.
The VSI structure is always looked up from the VF structure. The PF does
validate that the VSI ID provided matches a VSI associated with the VF, but
otherwise does not use the VSI ID for any purpose.

Instead of reporting the VSI number relative to the PF space, report a
fixed value of 1. When communicating with the VF over virtchnl, validate
that the VSI number is returned appropriately.

This avoids leaking information about the firmware of the PF state.
Currently the ice driver only supplies a VF with a single VSI. However, it
appears that virtchnl has some support for allowing multiple VSIs. I did
not attempt to implement this. However, space is left open to allow further
relative indexes if additional VSIs are provided in future feature
development. For this reason, keep the ice_vc_isvalid_vsi_id function in
place to allow extending it for multiple VSIs in the future.

This change will also simplify handling of live migration in a future
series. Since we no longer will provide a real VSI number to the VF, there
will be no need to keep track of this number when migrating to a new host.

Actually those buffers are used only by QMI target -> host communication.
And for WCN6855 and QCA6390, the largest packet size for that is less
than 6KB. So change buf_len field to 8KB, which results in order 1
allocation if page size is 4KB. In this way, we can at least save some
memory, and as well as decrease the possibility of allocation failure
in those scenarios.

9470114dfa net: pcs: xpcs: Return EINVAL in the internal methods
[ Upstream commit f5151005d3 ]

In particular the xpcs_soft_reset() and xpcs_do_config() functions
currently return -1 if invalid auto-negotiation mode is specified. That
value might be then passed to the generic kernel subsystems which require
a standard kernel errno value. Even though the erroneous conditions are
very specific (memory corruption or buggy driver implementation) using a
hard-coded -1 literal doesn't seem correct anyway especially when it comes
to passing it higher to the network subsystem or printing to the system
log.  Convert the hard-coded error values to -EINVAL then.

c39e75fae0 wifi: brcmfmac: Add DMI nvram filename quirk for ACEPC W5 Pro
[ Upstream commit 32167707aa ]

The ACEPC W5 Pro HDMI stick contains quite generic names in the sys_vendor
and product_name DMI strings, without this patch brcmfmac will try to load:
"brcmfmac43455-sdio.$(DEFAULT_STRING)-$(DEFAULT_STRING).txt" as nvram file
which is both too generic and messy with the $ symbols in the name.

The ACEPC W5 Pro uses the same Ampak AP6255 module as the ACEPC T8
and the nvram for the T8 is already in linux-firmware, so point the new
DMI nvram filename quirk to the T8 nvram file.

0a6def0576 wifi: rtw89: pci: enlarge RX DMA buffer to consider size of RX descriptor
[ Upstream commit c108b4a50d ]

Hardware puts RX descriptor and packet in RX DMA buffer, so it could be
over one buffer size if packet size is 11454, and then it will be split
into two segments. WiFi 7 chips use larger size of RX descriptor, so
enlarge DMA buffer size according to RX descriptor to have better
performance and simple flow.

3dac6ab4d9 bnx2x: Fix firmware version string character counts
[ Upstream commit 5642c82b94 ]

A potential string truncation was reported in bnx2x_fill_fw_str(),
when a long bp->fw_ver and a long phy_fw_ver might coexist, but seems
unlikely with real-world hardware.

Use scnprintf() to indicate the intent that truncations are tolerated.

While reading this code, I found a collection of various buffer size
counting issues. None looked like they might lead to a buffer overflow
with current code (the small buffers are 20 bytes and might only ever
consume 10 bytes twice with a trailing %NUL). However, early truncation
(due to a %NUL in the middle of the string) might be happening under
likely rare conditions. Regardless fix the formatters and related
functions:

- Switch from a separate strscpy() to just adding an additional "%s" to
  the format string that immediately follows it in bnx2x_fill_fw_str().
- Use sizeof() universally instead of using unbound defines.
- Fix bnx2x_7101_format_ver() and bnx2x_null_format_ver() to report the
  number of characters written, not including the trailing %NUL (as
  already done with the other firmware formatting functions).
- Require space for at least 1 byte in bnx2x_get_ext_phy_fw_version()
  for the trailing %NUL.
- Correct the needed buffer size in bnx2x_3_seq_format_ver().

This also ensures that error counters are not updated after we've

This is done for non-gPTP IPs. For gPTP IPs the driver PTP-specific
information was used to determine if receive function should be called. As
every IP has its own receive function that interrogates the RX descriptors
list in the same way the ravb_poll() was doing there is no need to double
check this in ravb_poll(). Removing the code from ravb_poll() leads to a

Separating this configuration from the ULP enabling flow and moving it to
the shutdown function allows enough time for the interface to settle and
avoids adding a delay.

[ Upstream commit 6dbdd4de03 ]

On some Meteor Lake systems accessing the PHY via the MDIO interface may
result in an MDI error. This issue happens sporadically and in most cases
a second access to the PHY via the MDIO interface results in success.

As a workaround, introduce a retry counter which is set to 3 on Meteor
Lake systems. The driver will only return an error if 3 consecutive PHY
access attempts fail. The retry mechanism is disabled in specific flows,
where MDI errors are expected.

e77220eec3 i40e: Remove circular header dependencies and fix headers

Similarly as for ice driver [1] there are also circular header
dependencies in i40e driver:
i40e.h -> i40e_virtchnl_pf.h -> i40e.h

Another issue is that i40e header files does not contain their own
dependencies on other header files (both private and standard) so their
inclusion in .c file require to add these deps in certain order to
that .c file to make it compilable.

Fix both issues by removal the mentioned circular dependency, by filling
i40e headers with their dependencies so they can be placed anywhere in
a source code. Additionally remove bunch of includes from i40e.h super
header file that are not necessary and include i40e.h only in .c files
that really require it.

66ca011a5d i40e: Enforce software interrupt during busy-poll exit
[ Upstream commit ea558de723 ]

As for ice bug fixed by commit b7306b42be ("ice: manage interrupts
during poll exit") followed by commit 23be7075b3 ("ice: fix software
generating extra interrupts") I'm seeing the similar issue also with
i40e driver.

In certain situation when busy-loop is enabled together with adaptive
coalescing, the driver occasionally misses that there are outstanding
descriptors to clean when exiting busy poll.

Try to catch the remaining work by triggering a software interrupt
when exiting busy poll. No extra interrupts will be generated when
busy polling is not used.

The issue was found when running sockperf ping-pong tcp test with
adaptive coalescing and busy poll enabled (50 as value busy_pool
and busy_read sysctl knobs) and results in huge latency spikes
with more than 100000us.

The fix is inspired from the ice driver and do the following:
1) During napi poll exit in case of busy-poll (napo_complete_done()
   returns false) this is recorded to q_vector that we were in busy
   loop.
2) Extends i40e_buildreg_itr() to be able to add an enforced software
   interrupt into built value
2) In i40e_update_enable_itr() enforces a software interrupt trigger
   if we are exiting busy poll to catch any pending clean-ups
3) Reuses unused 3rd ITR (interrupt throttle) index and set it to
   20K interrupts per second to limit the number of these sw interrupts.

e6d25dbd92 i40e: Remove _t suffix from enum type names
[ Upstream commit addca9175e ]

Enum type names should not be suffixed by '_t'. Either to use
'typedef enum name name_t' to so plain 'name_t var' instead of
'enum name_t var'.

0dcf573f99 i40e: fix vf may be used uninitialized in this function warning
commit f37c4eac99 upstream.

To fix the regression introduced by commit 52424f974b, which causes
servers hang in very hard to reproduce conditions with resets races.
Using two sources for the information is the root cause.
In this function before the fix bumping v didn't mean bumping vf
pointer. But the code used this variables interchangeably, so stale vf
could point to different/not intended vf.

Remove redundant "v" variable and iterate via single VF pointer across
whole function instead to guarantee VF pointer validity.

89e29416cf i40e: fix i40e_count_filters() to count only active/new filters
commit eb58c598ce upstream.

The bug usually affects untrusted VFs, because they are limited to 18 MACs,
it affects them badly, not letting to create MAC all filters.
Not stable to reproduce, it happens when VF user creates MAC filters
when other MACVLAN operations are happened in parallel.
But consequence is that VF can't receive desired traffic.

Fix counter to be bumped only for new or active filters.

76c39cf84c octeontx2-af: Add array index check
commit ef15ddeeb6 upstream.

In rvu_map_cgx_lmac_pf() the 'iter', which is used as an array index, can reach
value (up to 14) that exceed the size (MAX_LMAC_COUNT = 8) of the array.
Fix this bug by adding 'iter' value check.
