tcp: Disable header prediction for MD5 flow.
TCP socket saves the minimum required header length in tcp_header_len
of struct tcp_sock, and later the value is used in __tcp_fast_path_on()
to generate a part of TCP header in tcp_sock(sk)->pred_flags.
In tcp_rcv_established(), if the incoming packet has the same pattern
with pred_flags, we enter the fast path and skip full option parsing.
The MD5 option is parsed in tcp_v[46]_rcv(), so we need not parse it
again later in tcp_rcv_established() unless other options exist. We
add TCPOLEN_MD5SIG_ALIGNED to tcp_header_len in two paths to avoid the
slow path.
For passive open connections with MD5, we add TCPOLEN_MD5SIG_ALIGNED
to tcp_header_len in tcp_create_openreq_child() after 3WHS.
On the other hand, we do it in tcp_connect_init() for active open
connections. However, the value is overwritten while processing
SYN+ACK or crossed SYN in tcp_rcv_synsent_state_process().
These two cases will have the wrong value in pred_flags and never go
into the fast path.
We could update tcp_header_len in tcp_rcv_synsent_state_process(), but
a test with slightly modified netperf which uses MD5 for each flow shows
that the slow path is actually a bit faster than the fast path.
On c5.4xlarge EC2 instance (16 vCPU, 32 GiB mem)
$ for i in {1..10}; do
./super_netperf $(nproc) -H localhost -l 10 -- -m 256 -M 256;
done
Avg of 10
*
36e68eadd303 : 10.376 Gbps
* all fast path : 10.374 Gbps (patch v2, See Link)
* all slow path : 10.394 Gbps
The header prediction is not worth adding complexity for MD5, so let's
disable it for MD5.

platform driver.
The last patch is by Frank Jungclaus and adds support for the
CAN-USB/3 and CAN FD to the ESD USB CAN driver.

All struct members of the driver-facing APIs are documented twice,

I also get the feeling that a lot of developers will read the header
when coding, rather than the doc. Bring the two a little closer
together by using kdoc for structs and functions.
Using kdoc also gives us links (mentioning a function or struct

making the heads and tails out of this feature is not
trivial.
Obviously making the API more user friendly would be
a better fix, but until someone steps up to do that
let's at least document what the parameters are.

While poking at struct netdev_rx_queue I got annoyed by
the huge rebuild times. I split it out from netdevice.h
and then realized that it was the main reason we included
xdp.h in there. So I removed that dependency as well.
This gives us very pleasant build times for both xdp.h

xdp.h is far more specific and is included in only 67 other

Make xdp.h include netdevice.h, instead of the other way around.
This decreases the incremental allmodconfig builds size when
xdp.h is touched from 5947 to 662 objects.
Move bpf_prog_run_xdp() to xdp.h, seems appropriate and filter.h
is a mega-header in its own right so it's nice to avoid xdp.h

The only unfortunate part is that the typedef for xdp_features_t

udp6: Fix __ip6_append_data()'s handling of MSG_SPLICE_PAGES
__ip6_append_data() can has a similar problem to __ip_append_data()[1] when
asked to splice into a partially-built UDP message that has more than the
frag-limit data and up to the MTU limit, but in the ipv6 case, it errors
out with EINVAL. This can be triggered with something like:
pipe(pfd);
sfd = socket(AF_INET6, SOCK_DGRAM, 0);
connect(sfd, ...);
send(sfd, buffer, 8137, MSG_CONFIRM|MSG_MORE);
write(pfd[1], buffer, 8);
splice(pfd[0], 0, sfd, 0, 0x4ffe0ul, 0);
where the amount of data given to send() is dependent on the MTU size (in
this instance an interface with an MTU of 8192).
The problem is that the calculation of the amount to copy in
__ip6_append_data() goes negative in two places, but a check has been put
in to give an error in this case.
This happens because when pagedlen > 0 (which happens for MSG_ZEROCOPY and
MSG_SPLICE_PAGES), the terms in:
copy = datalen - transhdrlen - fraggap - pagedlen;
then mostly cancel when pagedlen is substituted for, leaving just -fraggap.
Fix this by:
(1) Insert a note about the dodgy calculation of 'copy'.
(2) If MSG_SPLICE_PAGES, clear copy if it is negative from the above
equation, so that 'offset' isn't regressed and 'length' isn't
increased, which will mean that length and thus copy should match the
amount left in the iterator.
(3) When handling MSG_SPLICE_PAGES, give a warning and return -EIO if
we're asked to splice more than is in the iterator. It might be
better to not give the warning or even just give a 'short' write.
(4) If MSG_SPLICE_PAGES, override the copy<0 check.
[!] Note that this should also affect MSG_ZEROCOPY, but that will return
-EINVAL for the range of send sizes that requires the skbuff to be split.

wifi: ath12k: avoid deadlock by change ieee80211_queue_work for regd_update_work
Deadlock is easily happened while shutdown wlan interface such as run
"ifconfig wlan0 down".
The reason is because when ar->regd_update_work is ran, it will
call wiphy_lock(ar->hw->wiphy) in function ath12k_regd_update() which
is running in workqueue of ieee80211_local queued by ieee80211_queue_work().
Another thread from "ifconfig wlan0 down" will also accuqire the lock
by wiphy_lock(sdata->local->hw.wiphy) in function ieee80211_stop(), and
then it call ieee80211_stop_device() to flush_workqueue(local->workqueue),
this will wait the workqueue of ieee80211_local finished. Then deadlock
will happen easily if the two thread run meanwhile.

wifi: ath12k: add handler for scan event WMI_SCAN_EVENT_DEQUEUED
When wlan interface is up, and 11d scan is sent to the firmware, then

normal scan from user space arrives to ath12k at this moment, then the
normal scan request is also sent to the firmware, but the scan started

CAN-USB/3 CAN FD interface.
Beside this patch there are the following to-do's left for follow-up
patches:
* In principle, the esd CAN-USB/3 supports Transmitter Delay
Compensation (TDC), but currently only the automatic TDC mode is
supported by this driver. An implementation for manual TDC
configuration will follow.
* Rework the code to no longer switch directly on the USB product IDs
to handle different device setting for each supported USB
device. Instead use the driver_info member within struct usb_device_id
to hold / point to specific properties for each supported device.
* Try to switch from synchronous send usb_bulk_msg() to asynchronous
communication by means of usb_submit_urb() where it is feasible.

udp: Fix __ip_append_data()'s handling of MSG_SPLICE_PAGES
__ip_append_data() can get into an infinite loop when asked to splice into
a partially-built UDP message that has more than the frag-limit data and up
to the MTU limit. Something like:
pipe(pfd);
sfd = socket(AF_INET, SOCK_DGRAM, 0);
connect(sfd, ...);
send(sfd, buffer, 8161, MSG_CONFIRM|MSG_MORE);
write(pfd[1], buffer, 8);
splice(pfd[0], 0, sfd, 0, 0x4ffe0ul, 0);
where the amount of data given to send() is dependent on the MTU size (in
this instance an interface with an MTU of 8192).
The problem is that the calculation of the amount to copy in
__ip_append_data() goes negative in two places, and, in the second place,
this gets subtracted from the length remaining, thereby increasing it.
This happens when pagedlen > 0 (which happens for MSG_ZEROCOPY and
MSG_SPLICE_PAGES), because the terms in:
copy = datalen - transhdrlen - fraggap - pagedlen;
then mostly cancel when pagedlen is substituted for, leaving just -fraggap.
This causes:
length -= copy + transhdrlen;
to increase the length to more than the amount of data in msg->msg_iter,
which causes skb_splice_from_iter() to be unable to fill the request and it
returns less than 'copied' - which means that length never gets to 0 and we
never exit the loop.
Fix this by:
(1) Insert a note about the dodgy calculation of 'copy'.
(2) If MSG_SPLICE_PAGES, clear copy if it is negative from the above
equation, so that 'offset' isn't regressed and 'length' isn't
increased, which will mean that length and thus copy should match the
amount left in the iterator.
(3) When handling MSG_SPLICE_PAGES, give a warning and return -EIO if
we're asked to splice more than is in the iterator. It might be
better to not give the warning or even just give a 'short' write.
[!] Note that this ought to also affect MSG_ZEROCOPY, but MSG_ZEROCOPY
avoids the problem by simply assuming that everything asked for got copied,
not just the amount that was in the iterator. This is a potential bug for
the future.

this series attempts to introduce new API for the hardware timestamping

I don't have any board with phylib hardware timestamping, so I would

because I also have some more unsubmitted conversions in progress:
