icmp: fix icmp_ext_echo_iio parsing in icmp_build_probe
In icmp_build_probe(), the icmp_ext_echo_iio parsing should be done
step by step and skb_header_pointer() return value should always be
checked, this patch fixes 3 places in there:
- On case ICMP_EXT_ECHO_CTYPE_NAME, it should only copy ident.name
from skb by skb_header_pointer(), its len is ident_len. Besides,
the return value of skb_header_pointer() should always be checked.
- On case ICMP_EXT_ECHO_CTYPE_INDEX, move ident_len check ahead of
skb_header_pointer(), and also do the return value check for
skb_header_pointer().
- On case ICMP_EXT_ECHO_CTYPE_ADDR, before accessing iio->ident.addr.
ctype3_hdr.addrlen, skb_header_pointer() should be called first,
then check its return value and ident_len.
On subcases ICMP_AFI_IP and ICMP_AFI_IP6, also do check for ident.
addr.ctype3_hdr.addrlen and skb_header_pointer()'s return value.
On subcase ICMP_AFI_IP, the len for skb_header_pointer() should be
"sizeof(iio->extobj_hdr) + sizeof(iio->ident.addr.ctype3_hdr) +
sizeof(struct in_addr)" or "ident_len".
v1->v2:
- To make it more clear, call skb_header_pointer() once only for
iio->indent's parsing as Jakub Suggested.
v2->v3:
- The extobj_hdr.length check against sizeof(_iio) should be done
before calling skb_header_pointer(), as Eric noticed.

sctp: account stream padding length for reconf chunk
sctp_make_strreset_req() makes repeated calls to sctp_addto_chunk()
which will automatically account for padding on each call. inreq and
outreq are already 4 bytes aligned, but the payload is not and doing
SCTP_PAD4(a + b) (which _sctp_make_chunk() did implicitly here) is
different from SCTP_PAD4(a) + SCTP_PAD4(b) and not enough. It led to
possible attempt to use more buffer than it was allocated and triggered
a BUG_ON.

mlxsw: thermal: Fix out-of-bounds memory accesses
Currently, mlxsw allows cooling states to be set above the maximum cooling state supported by the driver: # cat /sys/class/thermal/thermal_zone2/cdev0/type mlxsw_fan # cat /sys/class/thermal/thermal_zone2/cdev0/max_state 10 # echo 18 > /sys/class/thermal/thermal_zone2/cdev0/cur_state # echo $? 0 This results in out-of-bounds memory accesses when thermal state transition statistics are enabled (CONFIG_THERMAL_STATISTICS=y), as the transition table is accessed with a too large index (state) [1]. According to the thermal maintainer, it is the responsibility of the driver to reject such operations [2]. Therefore, return an error when the state to be set exceeds the maximum cooling state supported by the driver. To avoid dead code, as suggested by the thermal maintainer [3], partially revert commit |

ethernet: s2io: fix setting mac address during resume
After recent cleanups, gcc started warning about a suspicious
memcpy() call during the s2io_io_resume() function:
In function '__dev_addr_set',
inlined from 'eth_hw_addr_set' at include/linux/etherdevice.h:318:2,
inlined from 's2io_set_mac_addr' at drivers/net/ethernet/neterion/s2io.c:5205:2,
inlined from 's2io_io_resume' at drivers/net/ethernet/neterion/s2io.c:8569:7:
arch/x86/include/asm/string_32.h:182:25: error: '__builtin_memcpy' accessing 6 bytes at offsets 0 and 2 overlaps 4 bytes at offset 2 [-Werror=restrict]
182 | #define memcpy(t, f, n) __builtin_memcpy(t, f, n)
| ^~~~~~~~~~~~~~~~~~~~~~~~~
include/linux/netdevice.h:4648:9: note: in expansion of macro 'memcpy'
4648 | memcpy(dev->dev_addr, addr, len);
| ^~~~~~
What apparently happened is that an old cleanup changed the calling
conventions for s2io_set_mac_addr() from taking an ethernet address
as a character array to taking a struct sockaddr, but one of the
callers was not changed at the same time.
Change it to instead call the low-level do_s2io_prog_unicast() function
that still takes the old argument type.

net: dsa: felix: break at first CPU port during init and teardown
The NXP LS1028A switch has two Ethernet ports towards the CPU, but only
one of them is capable of acting as an NPI port at a time (inject and
extract packets using DSA tags).
However, using the alternative ocelot-8021q tagging protocol, it should
be possible to use both CPU ports symmetrically, but for that we need to
mark both ports in the device tree as DSA masters.
In the process of doing that, it can be seen that traffic to/from the
network stack gets broken, and this is because the Felix driver iterates
through all DSA CPU ports and configures them as NPI ports. But since
there can only be a single NPI port, we effectively end up in a
situation where DSA thinks the default CPU port is the first one, but
the hardware port configured to be an NPI is the last one.
I would like to treat this as a bug, because if the updated device trees
are going to start circulating, it would be really good for existing
kernels to support them, too.

net: dsa: tag_ocelot_8021q: fix inability to inject STP BPDUs into BLOCKING ports
When setting up a bridge with stp_state 1, topology changes are not
detected and loops are not blocked. This is because the standard way of
transmitting a packet, based on VLAN IDs redirected by VCAP IS2 to the
right egress port, does not override the port STP state (in the case of
Ocelot switches, that's really the PGID_SRC masks).
To force a packet to be injected into a port that's BLOCKING, we must
send it as a control packet, which means in the case of this tagger to
send it using the manual register injection method. We already do this
for PTP frames, extend the logic to apply to any link-local MAC DA.

net: dsa: felix: purge skb from TX timestamping queue if it cannot be sent
At present, when a PTP packet which requires TX timestamping gets
dropped under congestion by the switch, things go downhill very fast.
The driver keeps a clone of that skb in a queue of packets awaiting TX
timestamp interrupts, but interrupts will never be raised for the
dropped packets.
Moreover, matching timestamped packets to timestamps is done by a 2-bit
timestamp ID, and this can wrap around and we can match on the wrong skb.
Since with the default NPI-based tagging protocol, we get no notification
about packet drops, the best we can do is eventually recover from the
drop of a PTP frame: its skb will be dead memory until another skb which
was assigned the same timestamp ID happens to find it.
However, with the ocelot-8021q tagger which injects packets using the
manual register interface, it appears that we can check for more
information, such as:
- whether the input queue has reached the high watermark or not
- whether the injection group's FIFO can accept additional data or not
so we know that a PTP frame is likely to get dropped before actually
sending it, and drop it ourselves (because DSA uses NETIF_F_LLTX, so it
can't return NETDEV_TX_BUSY to ask the qdisc to requeue the packet).
But when we do that, we can also remove the skb from the timestamping
queue, because there surely won't be any timestamp that matches it.

net: dsa: tag_ocelot_8021q: break circular dependency with ocelot switch lib
Michael reported that when using the "ocelot-8021q" tagging protocol,
the switch driver module must be manually loaded before the tagging
protocol can be loaded/is available.
This appears to be the same problem described here:
https://lore.kernel.org/netdev/20210908220834.d7gmtnwrorhharna@skbuf/
where due to the fact that DSA tagging protocols make use of symbols
exported by the switch drivers, circular dependencies appear and this
breaks module autoloading.
The ocelot_8021q driver needs the ocelot_can_inject() and
ocelot_port_inject_frame() functions from the switch library. Previously
the wrong approach was taken to solve that dependency: shims were
provided for the case where the ocelot switch library was compiled out,
but that turns out to be insufficient, because the dependency when the
switch lib _is_ compiled is problematic too.
We cannot declare ocelot_can_inject() and ocelot_port_inject_frame() as
static inline functions, because these access I/O functions like
__ocelot_write_ix() which is called by ocelot_write_rix(). Making those
static inline basically means exposing the whole guts of the ocelot
switch library, not ideal...
We already have one tagging protocol driver which calls into the switch
driver during xmit but not using any exported symbol: sja1105_defer_xmit.
We can do the same thing here: create a kthread worker and one work item
per skb, and let the switch driver itself do the register accesses to
send the skb, and then consume it.

net: dsa: tag_ocelot: break circular dependency with ocelot switch lib driver
As explained here: https://lore.kernel.org/netdev/20210908220834.d7gmtnwrorhharna@skbuf/ DSA tagging protocol drivers cannot depend on symbols exported by switch drivers, because this creates a circular dependency that breaks module autoloading. The tag_ocelot.c file depends on the ocelot_ptp_rew_op() function exported by the common ocelot switch lib. This function looks at OCELOT_SKB_CB(skb) and computes how to populate the REW_OP field of the DSA tag, for PTP timestamping (the command: one-step/two-step, and the TX timestamp identifier). None of that requires deep insight into the driver, it is quite stateless, as it only depends upon the skb->cb. So let's make it a static inline function and put it in include/linux/dsa/ocelot.h, a file that despite its name is used by the ocelot switch driver for populating the injection header too - since commit |

net: mscc: ocelot: cross-check the sequence id from the timestamp FIFO with the skb PTP header
The sad reality is that when a PTP frame with a TX timestamping request
is transmitted, it isn't guaranteed that it will make it all the way to
the wire (due to congestion inside the switch), and that a timestamp
will be taken by the hardware and placed in the timestamp FIFO where an
IRQ will be raised for it.
The implication is that if enough PTP frames are silently dropped by the
hardware such that the timestamp ID has rolled over, it is possible to
match a timestamp to an old skb.
Furthermore, nobody will match on the real skb corresponding to this
timestamp, since we stupidly matched on a previous one that was stale in
the queue, and stopped there.
So PTP timestamping will be broken and there will be no way to recover.
It looks like the hardware parses the sequenceID from the PTP header,
and also provides that metadata for each timestamp. The driver currently
ignores this, but it shouldn't.
As an extra resiliency measure, do the following:
- check whether the PTP sequenceID also matches between the skb and the
timestamp, treat the skb as stale otherwise and free it
- if we see a stale skb, don't stop there and try to match an skb one
more time, chances are there's one more skb in the queue with the same
timestamp ID, otherwise we wouldn't have ever found the stale one (it
is by timestamp ID that we matched it).
While this does not prevent PTP packet drops, it at least prevents
the catastrophic consequences of incorrect timestamp matching.
Since we already call ptp_classify_raw in the TX path, save the result
in the skb->cb of the clone, and just use that result in the interrupt
code path.

net: mscc: ocelot: deny TX timestamping of non-PTP packets
It appears that Ocelot switches cannot timestamp non-PTP frames,
I tested this using the isochron program at:
https://github.com/vladimiroltean/tsn-scripts
with the result that the driver increments the ocelot_port->ts_id
counter as expected, puts it in the REW_OP, but the hardware seems to
not timestamp these packets at all, since no IRQ is emitted.
Therefore check whether we are sending PTP frames, and refuse to
populate REW_OP otherwise.

net: mscc: ocelot: warn when a PTP IRQ is raised for an unknown skb
When skb_match is NULL, it means we received a PTP IRQ for a timestamp
ID that the kernel has no idea about, since there is no skb in the
timestamping queue with that timestamp ID.
This is a grave error and not something to just "continue" over.
So print a big warning in case this happens.
Also, move the check above ocelot_get_hwtimestamp(), there is no point
in reading the full 64-bit current PTP time if we're not going to do
anything with it anyway for this skb.

net: mscc: ocelot: avoid overflowing the PTP timestamp FIFO
PTP packets with 2-step TX timestamp requests are matched to packets
based on the egress port number and a 6-bit timestamp identifier.
All PTP timestamps are held in a common FIFO that is 128 entry deep.
This patch ensures that back-to-back timestamping requests cannot exceed
the hardware FIFO capacity. If that happens, simply send the packets
without requesting a TX timestamp to be taken (in the case of felix,
since the DSA API has a void return code in ds->ops->port_txtstamp) or
drop them (in the case of ocelot).
I've moved the ts_id_lock from a per-port basis to a per-switch basis,
because we need separate accounting for both numbers of PTP frames in
flight. And since we need locking to inc/dec the per-switch counter,
that also offers protection for the per-port counter and hence there is
no reason to have a per-port counter anymore.

net: mscc: ocelot: make use of all 63 PTP timestamp identifiers
At present, there is a problem when user space bombards a port with PTP
event frames which have TX timestamping requests (or when a tc-taprio
offload is installed on a port, which delays the TX timestamps by a
significant amount of time). The driver will happily roll over the 2-bit
timestamp ID and this will cause incorrect matches between an skb and
the TX timestamp collected from the FIFO.
The Ocelot switches have a 6-bit PTP timestamp identifier, and the value
63 is reserved, so that leaves identifiers 0-62 to be used.
The timestamp identifiers are selected by the REW_OP packet field, and
are actually shared between CPU-injected frames and frames which match a
VCAP IS2 rule that modifies the REW_OP. The hardware supports
partitioning between the two uses of the REW_OP field through the
PTP_ID_LOW and PTP_ID_HIGH registers, and by default reserves the PTP
IDs 0-3 for CPU-injected traffic and the rest for VCAP IS2.
The driver does not use VCAP IS2 to set REW_OP for 2-step timestamping,
and it also writes 0xffffffff to both PTP_ID_HIGH and PTP_ID_LOW in
ocelot_init_timestamp() which makes all timestamp identifiers available
to CPU injection.
Therefore, we can make use of all 63 timestamp identifiers, which should
allow more timestampable packets to be in flight on each port. This is
only part of the solution, more issues will be addressed in future changes.

net: dsa: sja1105: break dependency between dsa_port_is_sja1105 and switch driver
It's nice to be able to test a tagging protocol with dsa_loop, but not
at the cost of losing the ability of building the tagging protocol and
switch driver as modules, because as things stand, there is a circular
dependency between the two. Tagging protocol drivers cannot depend on
switch drivers, that is a hard fact.
The reasoning behind the blamed patch was that accessing dp->priv should
first make sure that the structure behind that pointer is what we really
think it is.
Currently the "sja1105" and "sja1110" tagging protocols only operate
with the sja1105 switch driver, just like any other tagging protocol and
switch combination. The only way to mix and match them is by modifying
the code, and this applies to dsa_loop as well (by default that uses
DSA_TAG_PROTO_NONE). So while in principle there is an issue, in
practice there isn't one.
Until we extend dsa_loop to allow user space configuration, treat the
problem as a non-issue and just say that DSA ports found by tag_sja1105
are always sja1105 ports, which is in fact true. But keep the
dsa_port_is_sja1105 function so that it's easy to patch it during
testing, and rely on dead code elimination.

net: dsa: move sja1110_process_meta_tstamp inside the tagging protocol driver
The problem is that DSA tagging protocols really must not depend on the
switch driver, because this creates a circular dependency at insmod
time, and the switch driver will effectively not load when the tagging
protocol driver is missing.
The code was structured in the way it was for a reason, though. The DSA
driver-facing API for PTP timestamping relies on the assumption that
two-step TX timestamps are provided by the hardware in an out-of-band
manner, typically by raising an interrupt and making that timestamp
available inside some sort of FIFO which is to be accessed over
SPI/MDIO/etc.
So the API puts .port_txtstamp into dsa_switch_ops, because it is
expected that the switch driver needs to save some state (like put the
skb into a queue until its TX timestamp arrives).
On SJA1110, TX timestamps are provided by the switch as Ethernet
packets, so this makes them be received and processed by the tagging
protocol driver. This in itself is great, because the timestamps are
full 64-bit and do not require reconstruction, and since Ethernet is the
fastest I/O method available to/from the switch, PTP timestamps arrive
very quickly, no matter how bottlenecked the SPI connection is, because
SPI interaction is not needed at all.
DSA's code structure and strict isolation between the tagging protocol
driver and the switch driver break the natural code organization.
When the tagging protocol driver receives a packet which is classified
as a metadata packet containing timestamps, it passes those timestamps
one by one to the switch driver, which then proceeds to compare them
based on the recorded timestamp ID that was generated in .port_txtstamp.
The communication between the tagging protocol and the switch driver is
done through a method exported by the switch driver, sja1110_process_meta_tstamp.
To satisfy build requirements, we force a dependency to build the
tagging protocol driver as a module when the switch driver is a module.
However, as explained in the first paragraph, that causes the circular
dependency.
To solve this, move the skb queue from struct sja1105_private :: struct
sja1105_ptp_data to struct sja1105_private :: struct sja1105_tagger_data.
The latter is a data structure for which hacks have already been put
into place to be able to create persistent storage per switch that is
accessible from the tagging protocol driver (see sja1105_setup_ports).
With the skb queue directly accessible from the tagging protocol driver,
we can now move sja1110_process_meta_tstamp into the tagging driver
itself, and avoid exporting a symbol.

$ip link set dev pf0hpf master
$ip link add link bridge name vlan10 type vlan id 10 protocol 802.1q

ALSA: usb-audio: Add quirk for VF0770
The device advertises 8 formats, but only a rate of 48kHz is honored by the hardware and 24 bits give chopped audio, so only report the one working combination. This fixes out-of-the-box audio experience with PipeWire which otherwise attempts to choose S24_3LE (while PulseAudio defaulted to S16_LE).

ALSA: hda/realtek: Fix the mic type detection issue for ASUS G551JW
We need to define the codec pin 0x1b to be the mic, but somehow the mic doesn't support hot plugging detection, and Windows also has this issue, so we set it to phantom headset-mic. Also the determine_headset_type() often returns the omtp type by a mistake when we plug a ctia headset, this makes the mic can't record sound at all. Because most of the headset are ctia type nowadays and some machines have the fixed ctia type audio jack, it is possible this machine has the fixed ctia jack too. Here we set this mic jack to fixed ctia type, this could avoid the mic type detection mistake and make the ctia headset work stable.

Merge branch 'ioam-fixes'
Justin Iurman says:
====================
Correct the IOAM behavior for undefined trace type bits
(@Jakub @David: there will be a conflict for #2 when merging net->net-next, due
to commit [1]. The conflict is only 5-10 lines for #2 (#1 should be fine) inside
the file tools/testing/selftests/net/ioam6.sh, so quite short though possibly
ugly. Sorry for that, I didn't expect to post this one... Had I known, I'd have
made the opposite.)
Modify both the input and output behaviors regarding the trace type when one of
the undefined bits is set. The goal is to keep the interoperability when new
fields (aka new bits inside the range 12-21) will be defined.
The draft [2] says the following:
---------------------------------------------------------------
"Bit 12-21 Undefined. These values are available for future
assignment in the IOAM Trace-Type Registry (Section 8.2).
Every future node data field corresponding to one of
these bits MUST be 4-octets long. An IOAM encapsulating
node MUST set the value of each undefined bit to 0. If
an IOAM transit node receives a packet with one or more
of these bits set to 1, it MUST either:
1. Add corresponding node data filled with the reserved
value 0xFFFFFFFF, after the node data fields for the
IOAM-Trace-Type bits defined above, such that the
total node data added by this node in units of
4-octets is equal to NodeLen, or
2. Not add any node data fields to the packet, even for
the IOAM-Trace-Type bits defined above."
---------------------------------------------------------------
The output behavior has been modified to respect the fact that "an IOAM encap
node MUST set the value of each undefined bit to 0" (i.e., undefined bits can't
be set anymore).
As for the input behavior, current implementation is based on the second choice
(i.e., "not add any data fields to the packet [...]"). With this solution, any
interoperability is lost (i.e., if a new bit is defined, then an "old" kernel
implementation wouldn't fill IOAM data when such new bit is set inside the trace
type).
The input behavior is therefore relaxed and these undefined bits are now allowed
to be set. It is only possible thanks to the sentence "every future node data
field corresponding to one of these bits MUST be 4-octets long". Indeed, the
default empty value (the one for 4-octet fields) is inserted whenever an
undefined bit is set.

selftests: net: modify IOAM tests for undef bits
The output behavior for undefined bits is now directly tested inside the bash script. Trying to set an undefined bit should be refused. The input behavior for undefined bits has been removed due to the fact that we would need another sender allowed to set undefined bits.
