When fw fatal error occurs, poll health() first detects and reports on a
fw error. Afterwards, it detects and reports on the fw fatal error
itself.
That can cause a long delay in fw fatal error handling which waits in a
queue for the fw error handling to be finished. The fw error handle will
try asking for fw core dump command while fw in fatal state may not
respond and driver will wait for command timeout.
Changing the flow to detect and handle first fw fatal errors and only if
no fatal error detected look for a fw error to handle.

In commit 93a714d6b5 ("multicast: Extend ip address command to enable
multicast group join/leave on") we added a new flag IFA_F_MCAUTOJOIN
to make user able to add multicast address on ethernet interface.
This works for IPv4, but not for IPv6. See the inet6_addr_add code.
static int inet6_addr_add()
{
...
if (cfg->ifa_flags & IFA_F_MCAUTOJOIN) {
ipv6_mc_config(net->ipv6.mc_autojoin_sk, true...)
}
ifp = ipv6_add_addr(idev, cfg, true, extack); <- always fail with maddr
if (!IS_ERR(ifp)) {
...
} else if (cfg->ifa_flags & IFA_F_MCAUTOJOIN) {
ipv6_mc_config(net->ipv6.mc_autojoin_sk, false...)
}
}
But in ipv6_add_addr() it will check the address type and reject multicast
address directly. So this feature is never worked for IPv6.
We should not remove the multicast address check totally in ipv6_add_addr(),
but could accept multicast address only when IFA_F_MCAUTOJOIN flag supplied.

This reverts commit 96cce12ff6 ("cfg80211: fix processing world
regdomain when non modular").
Re-triggering a reg_process_hint with the last request on all events,
can make the regulatory domain fail in case of multiple WiFi modules. On
slower boards (espacially with mdev), enumeration of the WiFi modules
can end up in an intersected regulatory domain, and user cannot set it
with 'iw reg set' anymore.
This is happening, because:
- 1st module enumerates, queues up a regulatory request
- request gets processed by __reg_process_hint_driver():
- checks if previous was set by CORE -> yes
- checks if regulator domain changed -> yes, from '00' to e.g. 'US'
-> sends request to the 'crda'
- 2nd module enumerates, queues up a regulator request (which triggers
the reg_todo() work)
- reg_todo() -> reg_process_pending_hints() sees, that the last request
is not processed yet, so it tries to process it again.
__reg_process_hint driver() will run again, and:
- checks if the last request's initiator was the core -> no, it was
the driver (1st WiFi module)
- checks, if the previous initiator was the driver -> yes
- checks if the regulator domain changed -> yes, it was '00' (set by
core, and crda call did not return yet), and should be changed to 'US'
------> __reg_process_hint_driver calls an intersect
Besides, the reg_process_hint call with the last request is meaningless
since the crda call has a timeout work. If that timeout expires, the
first module's request will lost.

Fix two shortcomings in the Extended Key ID API:

activate pairwise keys with keyid 1 in the same way as for keyid 0,
simplifying the API usage for e.g. FILS and FT key installs.

in br_ipv6_multicast_mld2_report() with calls to ipv6_mc_may_pull(),
that returns -EINVAL on buffers too short to be valid IPv6 packets,
while maintaining the previous handling of the return code.
This leads to the direct opposite of the intended effect: if the
packet is malformed, -EINVAL evaluates as true, and we'll happily
proceed with the processing.
Return 0 if the packet is too short, in the same way as this was
fixed for IPv4 by commit 083b78a9ed ("ip: fix ip_mc_may_pull()

I don't have a reproducer for this, unlike the one referred to by

As Jason Baron explained in commit 790ba4566c ("tcp: set SOCK_NOSPACE
under memory pressure"), it is crucial we properly set SOCK_NOSPACE
when needed.
However, Jason patch had a bug, because the 'nonblocking' status
as far as sk_stream_wait_memory() is concerned is governed
by MSG_DONTWAIT flag passed at sendmsg() time :
long timeo = sock_sndtimeo(sk, flags & MSG_DONTWAIT);
So it is very possible that tcp sendmsg() calls sk_stream_wait_memory(),
and that sk_stream_wait_memory() returns -EAGAIN with SOCK_NOSPACE
cleared, if sk->sk_sndtimeo has been set to a small (but not zero)
value.
This patch removes the 'noblock' variable since we must always
set SOCK_NOSPACE if -EAGAIN is returned.
It also renames the do_nonblock label since we might reach this
code path even if we were in blocking mode.

The maximum key description size is 4095. Commit f771fde820 ("keys:
Simplify key description management") inadvertantly reduced that to 255
and made sizes between 256 and 4095 work weirdly, and any size whereby
size & 255 == 0 would cause an assertion in __key_link_begin() at the
following line:
BUG_ON(index_key->desc_len == 0);
This can be fixed by simply increasing the size of desc_len in struct
keyring_index_key to a u16.
Note the argument length test in keyutils only checked empty
descriptions and descriptions with a size around the limit (ie. 4095)
and not for all the values in between, so it missed this. This has been

This patch adds initial support for offloading basechains using the
priority range from 1 to 65535. This is restricting the netfilter
priority range to 16-bit integer since this is what most drivers assume
so far from tc. It should be possible to extend this range of supported

tc transparently maps the software priority number to hardware. Update
it to pass the major priority which is what most drivers expect. Update
drivers too so they do not need to lshift the priority field of the
flow_cls_common_offload object. The stmmac driver is an exception, since
this code assumes the tc software priority is fine, therefore, lshift it
just to be conservative.

In i2400m_barker_db_init(), 'options_orig' is allocated through kstrdup()
to hold the original command line options. Then, the options are parsed.
However, if an error occurs during the parsing process, 'options_orig' is
not deallocated, leading to a memory leak bug. To fix this issue, free
'options_orig' before returning the error.

The driver name gets exposed in sysfs under /sys/bus/pci/drivers
so it should look like other devices. Change it to be common
format (instead of "Cavium PTP").
This is a trivial fix that was observed by accident because
Debian kernels were building this driver into kernel (bug).

There's no need to wait until a completion is received to unmap
TX descriptor buffers that have been passed to the hypervisor.
Instead unmap it when the hypervisor call has completed. This patch
avoids the possibility that a buffer will not be unmapped because
a TX completion is lost or mishandled.

FW expects the driver to provide unique flow reference handles
for Tx or Rx flows. When a Tx flow and an Rx flow end up sharing
a reference handle, flow offload does not seem to work.
This could happen in the case of 2 flows having their L2 fields
wildcarded but in different direction.
Fix to incorporate the flow direction as part of the L2 key
v2: Move the dir field to the end of the bnxt_tc_l2_key struct to
fix the warning reported by kbuild test robot <lkp@intel.com>.
There is existing code that initializes the structure using
nested initializer and will warn with the new u8 field added to
the beginning. The structure also packs nicer when this new u8 is
added to the end of the structure [MChan].

Direction of the flow is determined using src_fid. For an RX flow,
src_fid is PF's fid and for TX flow, src_fid is VF's fid. Direction
of the flow must be specified, when getting statistics for that flow.
Currently, for DECAP flow, direction is determined incorrectly, i.e.,
direction is initialized as TX for DECAP flow, instead of RX. Because
of which, stats are not reported for this DECAP flow, though it is
offloaded and there is traffic for that flow, resulting in flow age out.
This patch fixes the problem by determining the DECAP flow's direction
using correct fid. Set the flow direction in all cases for consistency
even if 64-bit flow handle is not used.

When both RX buffers and RX aggregation buffers have to be
replenished at the end of NAPI, post the RX aggregation buffers first
before RX buffers. Otherwise, we may run into a situation where
there are only RX buffers without RX aggregation buffers for a split
second. This will cause the hardware to abort the RX packet and
report buffer errors, which will cause unnecessary cleanup by the
driver.
Ringing the Aggregation ring doorbell first before the RX ring doorbell
will prevent some of these buffer errors. Use the same sequence during
ring initialization as well.

During device shutdown, the VNIC clearing sequence needs to be modified
to free the VNIC first before freeing the RSS contexts. The current
code is doing the reverse and we can get mis-directed RX completions
to CP ring ID 0 when the RSS contexts are freed and zeroed. The clearing
of RSS contexts is not required with the new sequence.
Refactor the VNIC clearing logic into a new function bnxt_clear_vnic()
and do the chip specific VNIC clearing sequence.

that as a part of VF's reload flow, VLANs created on the VF

This patch clears the vlan metadata/info so that VLANs gets
