ipv6/addrconf: allow adding multicast addr if IFA_F_MCAUTOJOIN is set
In commit
93a714d6b53d ("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.

Revert "cfg80211: fix processing world regdomain when non modular"
This reverts commit
96cce12ff6e0 ("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.

ipv6: Fix return value of ipv6_mc_may_pull() for malformed packets
Commit
ba5ea614622d ("bridge: simplify ip_mc_check_igmp() and

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
083b78a9ed64 ("ip: fix ip_mc_may_pull()

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

tcp: make sure EPOLLOUT wont be missed
As Jason Baron explained in commit
790ba4566c1a ("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.

flow_offload hardware priority fixes
This patchset contains two updates for the flow_offload users:
1) Pass the major tc priority to drivers so they do not have to
lshift it. This is a preparation patch for the fix coming in
patch #2.
2) Set the hardware priority from the netfilter basechain priority,
some drivers break when using the existing hardware priority
number that is set to zero.

This patch adds initial support for offloading basechains using the

so far from tc. It should be possible to extend this range of supported

bnxt_en: Fix to include flow direction in L2 key
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

bnxt_en: Use correct src_fid to determine direction of the flow
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.

tipc: fix false detection of retransmit failures
This commit eliminates the use of the link 'stale_limit' & 'prev_from'
(besides the already removed - 'stale_cnt') variables in the detection
of repeated retransmit failures as there is no proper way to initialize
them to avoid a false detection, i.e. it is not really a retransmission
failure but due to a garbage values in the variables.
Instead, a jiffies variable will be added to individual skbs (like the
way we restrict the skb retransmissions) in order to mark the first skb
retransmit time. Later on, at the next retransmissions, the timestamp
will be checked to see if the skb in the link transmq is "too stale",
that is, the link tolerance time has passed, so that a link reset will
be ordered. Note, just checking on the first skb in the queue is fine
enough since it must be the oldest one.
A counter is also added to keep track the actual skb retransmissions'
number for later checking when the failure happens.
The downside of this approach is that the skb->cb[] buffer is about to
be exhausted, however it is always able to allocate another memory area
and keep a reference to it when needed.

liquidio: add cleanup in octeon_setup_iq()
If oct->fn_list.enable_io_queues() fails, no cleanup is executed, leading
to memory/resource leaks. To fix this issue, invoke

net/mlx5e: Fix compatibility issue with ethtool flash device
Cited patch deleted ethtool flash device support, as ethtool core can
fallback into devlink flash callback. However, this is supported only if
there is a devlink port registered over the corresponding netdevice.
As mlx5e do not have devlink port support over native netdevice, it broke
the ability to flash device via ethtool.
This patch re-add the ethtool callback to avoid user functionality breakage
when trying to flash device via ethtool.

io_uring: fix an issue when IOSQE_IO_LINK is inserted into defer list
This patch may fix two issues:
First, when IOSQE_IO_DRAIN set, the next IOs need to be inserted into
defer list to delay execution, but link io will be actively scheduled to
run by calling io_queue_sqe.
Second, when multiple LINK_IOs are inserted together with defer_list,

io_uring: fix manual setup of iov_iter for fixed buffers
Commit
bd11b3a391e3 ("io_uring: don't use iov_iter_advance() for fixed
buffers") introduced an optimization to avoid using the slow
iov_iter_advance by manually populating the iov_iter iterator in some
cases.
However, the computation of the iterator count field was erroneous: The
first bvec was always accounted for an extent of page size even if the
bvec length was smaller.
In consequence, some I/O operations on fixed buffers were unable to
operate on the full extent of the buffer, consistently skipping some
bytes at the end of it.
