After restart, we might want to end up with the same config
as before, even for multi-link/EMLSR. Therefore, don't reset
the stored link selection result in that case.

When there's an active link in a non-station vif, the station vif is
not allowed to enter EMLSR
Note that blocking EMLSR by calling iwl_mvm_block_esr() we will schedule
an exit from EMLSR worker, but the worker cannot run before the
activation of the non-BSS link, as ieee80211_remain_on_channel already
holds the wiphy mutex.
Handle that by explicitly calling ieee80211_set_active_links()
to leave EMLSR, and then doing iwl_mvm_block_esr() only for
consistency and to avoid re-entering it before ready.
Note that a call to ieee80211_set_active_links requires to release the
mvm mutex, but that's ok since we still hold the wiphy lock. The only
thing that might race here is the ESR_MODE_NOTIF, so this changes its
handler to run under the wiphy lock.

If CSA is happening, then exit EMLSR to keep the better link,
which is the primary link unless that's doing the CSA with
quiet. This is done because we can't transmit the OMN frame
on a quiet link, but want to exit EMLSR during CSA for better
beacon reception, so we can follow the switch accurately.

The new link selection algorithm uses defaults values for BSS load if
the BSS Load element was not published by the AP.
For 6 GHz, that value is 0. So if the best link is 6 GHz, the EMLSR
grade to always be equal to the grade of the best link,
and then the best link grade is getting a bonus of 10 percent, meaning
that we will never activate EMLSR.
Change the logic to not give a bonus for the best link.

When non default TTLM is applied, mac80211 may force us to use a specific
link (For example, if the only active link becomes a dormant link,
mac80211 will pick the first usable link and set it as active).
When default TTLM is applied, we have new usable links that we might want
to select. Therefore, trigger MLO scan and link selection upon change in
TTLM.

When an event occurs to unblock EMLSR, the code attempts to re-enable
EMLSR. However, the current implementation always tries to activate
EMLSR, regardless of whether the blocker was set before the unblocking
event or not. If EMLSR was already unblocked, there is no need to
re-activate it.

If the reason for exiting EMLSR was a blocking reason, wait for the
corresponding unblocking event:
- if there is an ongoing scan - do nothing. Link selection will be
triggered at the end of it.
- If more than 30 seconds passed since the exit, trigger MLO scan, which
will trigger link selection
- If less then 30 seconds passed since exit, reuse the latest link
selection result
If the reason for exiting EMLSR was an exit reason (IWL_MVM_EXIT_*),
schedule MLO scan in 30 seconds.

BT Coex disables EMLSR only for a 2.4 GHz link, but doesn't block the
vif from using EMLSR with a different link pair. In addition, storing it
in mvmvif:disable_esr_reason requires extracting the BT Coex bit before
checking if EMLSR is blocked or not for a specific vif.
Therefore, change the BT Coex bit to be an exit reason and not a
blocker. On link selection, EMLSR mode will be re-calculated for the 2.4
GHz link instead of checking that bit.
While at it, move the relevant function declarations to the EMLSR
functions area in mvm.h

The existing code uses iter->type to figure out what data is needed, the
live copy (READ) or clone (UPDATE).
Without pending updates, priv->clone and priv->match will point to
different memory locations, but they have identical content.
Future patch will make priv->clone == NULL if there are no pending changes,
in this case we must copy the live data for the UPDATE case.
Currently this would require GFP_ATOMIC allocation. Split the walk
function in two parts: one that does the walk and one that decides which
data is needed.
In the UPDATE case, callers hold the transaction mutex so we do not need
the rcu read lock. This allows to use GFP_KERNEL allocation while
cloning.

Currently it returns an error pointer, but the only possible failure
is ENOMEM.
After a followup patch, we'd need to discard the errno code, i.e.
x = pipapo_clone()
if (IS_ERR(x))
return NULL
or make more changes to fix up callers to expect IS_ERR() code
from set->ops->deactivate().
So simplify this and make it return ptr-or-null.

Not sure why this special case exists. Early drop logic
(which kicks in when conntrack table is full) should be independent
of flowtable offload and only consider assured bit (i.e., two-way
traffic was seen).
flowtable entries hold a reference to the conntrack entry (struct
nf_conn) that has been offloaded. The conntrack use count is not
decremented until after the entry is free'd.
This change therefore will not result in exceeding the conntrack table
limit. It does allow early-drop of tcp flows even when they've been
offloaded, but only if they have been offloaded before syn-ack was
received or after at least one peer has sent a fin.
Currently 'fin' packet reception already stops offloading, so this
should not impact offloading either.

At the beginning in 2009 one patch [1] introduced collecting drop
counter in nf_conntrack_in() by returning -NF_DROP. Later, another
patch [2] changed the return value of tcp_packet() which now is
renamed to nf_conntrack_tcp_packet() from -NF_DROP to NF_DROP. As
we can see, that -NF_DROP should be corrected.
Similarly, there are other two points where the -NF_DROP is used.
Well, as NF_DROP is equal to 0, inverting NF_DROP makes no sense
as patch [2] said many years ago.

The race condition around the ECCCLR register access happens in the IRQ
disable method called in the device remove() procedure and in the ECC IRQ
handler:
1. Enable IRQ:
a. ECCCLR = EN_CE | EN_UE
2. Disable IRQ:
a. ECCCLR = 0
3. IRQ handler:
a. ECCCLR = CLR_CE | CLR_CE_CNT | CLR_CE | CLR_CE_CNT
b. ECCCLR = 0
c. ECCCLR = EN_CE | EN_UE
So if the IRQ disabling procedure is called concurrently with the IRQ
handler method the IRQ might be actually left enabled due to the
statement 3c.
The root cause of the problem is that ECCCLR register (which since
v3.10a has been called as ECCCTL) has intermixed ECC status data clear
flags and the IRQ enable/disable flags. Thus the IRQ disabling (clear EN
flags) and handling (write 1 to clear ECC status data) procedures must
be serialised around the ECCCTL register modification to prevent the
race.
So fix the problem described above by adding the spin-lock around the
ECCCLR modifications and preventing the IRQ-handler from modifying the
IRQs enable flags (there is no point in disabling the IRQ and then
re-enabling it again within a single IRQ handler call, see the
statements 3a/3b and 3c above).

net_alloc_generic is called by net_alloc, which is called without any
locking. It reads max_gen_ptrs, which is changed under pernet_ops_rwsem. It
is read twice, first to allocate an array, then to set s.len, which is
later used to limit the bounds of the array access.
It is possible that the array is allocated and another thread is
registering a new pernet ops, increments max_gen_ptrs, which is then used
to set s.len with a larger than allocated length for the variable array.
Fix it by reading max_gen_ptrs only once in net_alloc_generic. If
max_gen_ptrs is later incremented, it will be caught in net_assign_generic.

All EV4 machines are already gone, and the remaining EV5 based machines
all support the slightly more modern EV56 generation as well.
Debian only supports EV56 and later.
Drop both of these and build kernels optimized for EV56 and higher
when the "generic" options is selected, tuning for an out-of-order
EV6 pipeline, same as Debian userspace.
Since this was the only supported architecture without 8-bit and
16-bit stores, common kernel code no longer has to worry about
aligning struct members, and existing workarounds from the block
and tty layers can be removed.
The alpha memory management code no longer needs an abstraction
for the differences between EV4 and EV5+.

Felix Fietkau says:
====================
Add TCP fraglist GRO support
When forwarding TCP after GRO, software segmentation is very expensive,
especially when the checksum needs to be recalculated.
One case where that's currently unavoidable is when routing packets over
PPPoE. Performance improves significantly when using fraglist GRO
implemented in the same way as for UDP.
When NETIF_F_GRO_FRAGLIST is enabled, perform a lookup for an established
socket in the same netns as the receiving device. While this may not
cover all relevant use cases in multi-netns configurations, it should be
good enough for most configurations that need this.
Here's a measurement of running 2 TCP streams through a MediaTek MT7622
device (2-core Cortex-A53), which runs NAT with flow offload enabled from
one ethernet port to PPPoE on another ethernet port + cake qdisc set to
1Gbps.
rx-gro-list off: 630 Mbit/s, CPU 35% idle
rx-gro-list on: 770 Mbit/s, CPU 40% idle
Changes since v4:
- add likely() to prefer the non-fraglist path in check
Changes since v3:
- optimize __tcpv4_gso_segment_csum
- add unlikely()
- reorder dev_net/skb_gro_network_header calls after NETIF_F_GRO_FRAGLIST
check
- add support for ipv6 nat
- drop redundant pskb_may_pull check
Changes since v2:
- create tcp_gro_header_pull helper function to pull tcp header only once
- optimize __tcpv4_gso_segment_list_csum, drop obsolete flags check
Changes since v1:
- revert bogus tcp flags overwrite on segmentation
- fix kbuild issue with !CONFIG_IPV6
- only perform socket lookup for the first skb in the GRO train
Changes since RFC:
- split up patches
- handle TCP flags mutations

Preparation for adding TCP fraglist GRO support. It expects packets to be
combined in a similar way as UDP fraglist GSO packets.
For IPv4 packets, NAT is handled in the same way as UDP fraglist GSO.

The PTP_CMD_CTL is a self clearing register which controls the PTP clock
values. In the current implementation driver waits for a duration of 20
sec in case of HW failure to clear the PTP_CMD_CTL register bit. This
timeout of 20 sec is very long to recognize a HW failure, as it is
typically cleared in one clock(<16ns). Hence reducing the timeout to 1 sec
would be sufficient to conclude if there is any HW failure observed. The
usleep_range will sleep somewhere between 1 msec to 20 msec for each
iteration. By setting the PTP_CMD_CTL_TIMEOUT_CNT to 50 the max timeout
is extended to 1 sec.

It would be better not to drop skb in conntrack unless we have good
alternatives. So we can treat the result of testing skb's header
pointer as nf_conntrack_tcp_packet() does.

So far Multicast Router Advertisements and Multicast Router
Solicitations from the Multicast Router Discovery protocol (RFC4286)
would be marked as INVALID for IPv6, even if they are in fact intact
and adhering to RFC4286.
This broke MRA reception and by that multicast reception on
IPv6 multicast routers in a Proxmox managed setup, where Proxmox
would install a rule like "-m conntrack --ctstate INVALID -j DROP"
at the top of the FORWARD chain with br-nf-call-ip6tables enabled
by default.
Similar to as it's done for MLDv1, MLDv2 and IPv6 Neighbor Discovery
already, fix this issue by excluding MRD from connection tracking
handling as MRD always uses predefined multicast destinations
for its messages, too. This changes the ct-state for ICMPv6 MRD messages
from INVALID to UNTRACKED.
This issue was found and fixed with the help of the mrdisc tool
(https://github.com/troglobit/mrdisc).

Turn update into noop as a follow up for:
9fedd894b4e1 ("netfilter: nf_tables: fix unexpected EOPNOTSUPP error")
instead of adding a transaction object which is simply discarded at a
later stage of the commit protocol.

The pointer to fw_packet structure is passed to ring buffer of tracepoints
framework as the value of u64 type. '0x%016llx' is used for the print
format of value, while the flag and width are useless in the case.
This commit removes them.

The core function expects hardware drivers to call
fw_core_handle_bus_reset() when changing bus topology. The 1394 OHCI
driver calls it when handling selfID event as a result of any bus-reset.
This commit adds a tracepoints event for it.
