A number of fixes that have built up for SPI, a bunch of driver specific
ones including an unfortunate revert of an optimisation for the i.MX
driver which was causing issues with some configurations, plus a couple
of core fixes for the rarely used octal mode and for a bad interaction
between multi-CS support and target mode.

Lots of (mostly boring) fixes for syzbot bugs and rare(r) CI bugs.
The LRU_TIME_BITS fix was slightly more involved; we only have 48 bits
for the LRU position (we would prefer 64), so wraparound is possible for
the cached data LRUs on a filesystem that has done sufficient
(petabytes) reads; this is now handled.
One notable user reported bugfix, where we were forgetting to correctly
set the bucket data type, which should have been BCH_DATA_need_gc_gens
instead of BCH_DATA_free; this was causing us to go emergency read-only
on a filesystem that had seen heavy enough use to see bucket gen
wraparoud.
We're now starting to fix simple (safe) errors without requiring user
intervention - i.e. a small incremental step towards full self healing.
This is currently limited to just certain allocation information
counters, and the error is still logged in the superblock; see that
patch for more information. ("bcachefs: Fix safe errors by default").

A small prescaler is beneficial, as this improves the resolution of the
duty_cycle configuration. However if the prescaler is too small, the
maximal possible period becomes considerably smaller than the requested
value.
One situation where this goes wrong is the following: With a parent
clock rate of 208877930 Hz and max_arr = 0xffff = 65535, a request for
period = 941243 ns currently results in PSC = 1. The value for ARR is
then calculated to
ARR = 941243 * 208877930 / (1000000000 * 2) - 1 = 98301
This value is bigger than 65535 however and so doesn't fit into the
respective register field. In this particular case the PWM was
configured for a period of 313733.4806027616 ns (with ARR = 98301 &
0xffff). Even if ARR was configured to its maximal value, only period =
627495.6861167669 ns would be achievable.
Fix the calculation accordingly and adapt the comment to match the new
algorithm.
With the calculation fixed the above case results in PSC = 2 and so an
actual period of 941229.1667195285 ns.

There are 2 types of outstanding tx skb's:
Type 1: Packets that are sitting in the drivers ind_buff that are
waiting to be batch sent to the NIC. During a device reset, these are
freed with a call to ibmvnic_tx_scrq_clean_buffer()
Type 2: Packets that have been sent to the NIC and are awaiting a TX
completion IRQ. These are free'd during a reset with a call to
clean_tx_pools()
During any reset which requires us to free the tx irq, ensure that the
Type 2 skb references are freed. Since the irq is released, it is
impossible for the NIC to inform of any completions.
Furthermore, later in the reset process is a call to init_tx_pools()
which marks every entry in the tx pool as free (ie not outstanding).
So if the driver is to make a call to init_tx_pools(), it must first
be sure that the tx pool is empty of skb references.
This issue was discovered by observing the following in the logs during
EEH testing:
TX free map points to untracked skb (tso_pool 0 idx=4)
TX free map points to untracked skb (tso_pool 0 idx=5)
TX free map points to untracked skb (tso_pool 1 idx=36)

Ensure the inner IP header is part of the skb's linear data before
setting old_iph. Otherwise, on a non-linear skb, old_iph could point
outside of the packet data.
Unlike classical VXLAN, which always encapsulates Ethernet packets,
VXLAN-GPE can transport IP packets directly. In that case, we need to
look at skb->protocol to figure out if an Ethernet header is present.

The BPF ring buffer internally is implemented as a power-of-2 sized circular
buffer, with two logical and ever-increasing counters: consumer_pos is the
consumer counter to show which logical position the consumer consumed the
data, and producer_pos which is the producer counter denoting the amount of
data reserved by all producers.
Each time a record is reserved, the producer that "owns" the record will
successfully advance producer counter. In user space each time a record is
read, the consumer of the data advanced the consumer counter once it finished
processing. Both counters are stored in separate pages so that from user
space, the producer counter is read-only and the consumer counter is read-write.
One aspect that simplifies and thus speeds up the implementation of both
producers and consumers is how the data area is mapped twice contiguously
back-to-back in the virtual memory, allowing to not take any special measures
for samples that have to wrap around at the end of the circular buffer data
area, because the next page after the last data page would be first data page
again, and thus the sample will still appear completely contiguous in virtual
memory.
Each record has a struct bpf_ringbuf_hdr { u32 len; u32 pg_off; } header for
book-keeping the length and offset, and is inaccessible to the BPF program.
Helpers like bpf_ringbuf_reserve() return `(void *)hdr + BPF_RINGBUF_HDR_SZ`
for the BPF program to use. Bing-Jhong and Muhammad reported that it is however
possible to make a second allocated memory chunk overlapping with the first
chunk and as a result, the BPF program is now able to edit first chunk's
header.
For example, consider the creation of a BPF_MAP_TYPE_RINGBUF map with size
of 0x4000. Next, the consumer_pos is modified to 0x3000 /before/ a call to
bpf_ringbuf_reserve() is made. This will allocate a chunk A, which is in
[0x0,0x3008], and the BPF program is able to edit [0x8,0x3008]. Now, lets
allocate a chunk B with size 0x3000. This will succeed because consumer_pos
was edited ahead of time to pass the `new_prod_pos - cons_pos > rb->mask`
check. Chunk B will be in range [0x3008,0x6010], and the BPF program is able
to edit [0x3010,0x6010]. Due to the ring buffer memory layout mentioned
earlier, the ranges [0x0,0x4000] and [0x4000,0x8000] point to the same data
pages. This means that chunk B at [0x4000,0x4008] is chunk A's header.
bpf_ringbuf_submit() / bpf_ringbuf_discard() use the header's pg_off to then
locate the bpf_ringbuf itself via bpf_ringbuf_restore_from_rec(). Once chunk
B modified chunk A's header, then bpf_ringbuf_commit() refers to the wrong
page and could cause a crash.
Fix it by calculating the oldest pending_pos and check whether the range
from the oldest outstanding record to the newest would span beyond the ring
buffer size. If that is the case, then reject the request. We've tested with
the ring buffer benchmark in BPF selftests (./benchs/run_bench_ringbufs.sh)
before/after the fix and while it seems a bit slower on some benchmarks, it
is still not significantly enough to matter.

When the following program is processed by the verifier:
L1: may_goto L2
goto L1
L2: w0 = 0
exit
the may_goto insn is first converted to:
L1: r11 = *(u64 *)(r10 -8)
if r11 == 0x0 goto L2
r11 -= 1
*(u64 *)(r10 -8) = r11
goto L1
L2: w0 = 0
exit
then later as the last step the verifier inserts:
*(u64 *)(r10 -8) = BPF_MAX_LOOPS
as the first insn of the program to initialize loop count.
When the first insn happens to be a branch target of some jmp the
bpf_patch_insn_data() logic will produce:
L1: *(u64 *)(r10 -8) = BPF_MAX_LOOPS
r11 = *(u64 *)(r10 -8)
if r11 == 0x0 goto L2
r11 -= 1
*(u64 *)(r10 -8) = r11
goto L1
L2: w0 = 0
exit
because instruction patching adjusts all jmps and calls, but for this
particular corner case it's incorrect and the L1 label should be one
instruction down, like:
*(u64 *)(r10 -8) = BPF_MAX_LOOPS
L1: r11 = *(u64 *)(r10 -8)
if r11 == 0x0 goto L2
r11 -= 1
*(u64 *)(r10 -8) = r11
goto L1
L2: w0 = 0
exit
and that's what this patch is fixing.
After bpf_patch_insn_data() call adjust_jmp_off() to adjust all jmps
that point to newly insert BPF_ST insn to point to insn after.
Note that bpf_patch_insn_data() cannot easily be changed to accommodate
this logic, since jumps that point before or after a sequence of patched
instructions have to be adjusted with the full length of the patch.
Conceptually it's somewhat similar to "insert" of instructions between other
instructions with weird semantics. Like "insert" before 1st insn would require
adjustment of CALL insns to point to newly inserted 1st insn, but not an
adjustment JMP insns that point to 1st, yet still adjusting JMP insns that
cross over 1st insn (point to insn before or insn after), hence use simple
adjust_jmp_off() logic to fix this corner case. Ideally bpf_patch_insn_data()
would have an auxiliary info to say where 'the start of newly inserted patch
is', but it would be too complex for backport.

The following two shared buffer operations make use of the Shared Buffer
Status Register (SBSR):
# devlink sb occupancy snapshot pci/0000:01:00.0
# devlink sb occupancy clearmax pci/0000:01:00.0
The register has two masks of 256 bits to denote on which ingress /
egress ports the register should operate on. Spectrum-4 has more than
256 ports, so the register was extended by cited commit with a new
'port_page' field.
However, when filling the register's payload, the driver specifies the
ports as absolute numbers and not relative to the first port of the port
page, resulting in memory corruptions [1].
Fix by specifying the ports relative to the first port of the port page.

Cited commit added support for a new reset flow ("all reset") which is
deeper than the existing reset flow ("software reset") and allows the
device's PCI firmware to be upgraded.
In the new flow the driver first tells the firmware that "all reset" is
required by issuing a new reset command (i.e., MRSR.command=6) and then
triggers the reset by having the PCI core issue a secondary bus reset
(SBR).
However, due to a race condition in the device's firmware the device is
not always able to recover from this reset, resulting in initialization
failures [1].
New firmware versions include a fix for the bug and advertise it using a
new capability bit in the Management Capabilities Mask (MCAM) register.
Avoid initialization failures by reading the new capability bit and
triggering the new reset flow only if the bit is set. If the bit is not
set, trigger a normal PCI hot reset by skipping the call to the
Management Reset and Shutdown Register (MRSR).
Normal PCI hot reset is weaker than "all reset", but it results in a
fully operational driver and allows users to flash a new firmware, if
they want to.
