Eric reported that syzkaller triggered a splat in tcp_cleanup_ulp()
where assertion sock_owned_by_me() failed. This happened through
inet_csk_prepare_forced_close() first releasing the socket lock,
then calling into tcp_done(newsk) which is called after the
inet_csk_prepare_forced_close() and therefore without the socket
lock held. The sock_owned_by_me() assertion can generally be
removed as the only place where tcp_cleanup_ulp() is called from
now is out of inet_csk_destroy_sock() -> sk->sk_prot->destroy()
where socket is in dead state and unreachable. Therefore, add a

Some cleanup and bugfix for desc filling
When retransmiting packets, skb_cow_head which is called in
hns3_set_tso may clone a new header. And driver will clear the
checksum of the header after doing DMA map, so HW will read the
old header whose L3 checksum is not cleared and calculate a
wrong L3 checksum.
Also When sending a big fragment using multiple buffer descriptor,
hns3 does one maping, but do multiple unmapping when tx is done,
which may cause unmapping problem.

Align the use of local PTT to propagate through the qed_mcp* API's.
Global ptt should not be used.
Register access should be done through layers. Register address is
mapped into a PTT, PF translation table. Several interface functions
require a PTT to direct read/write into register. There is a pool of
PTT maintained, and several PTT are used simultaneously to access
device registers in different flows. Same PTT should not be used in
flows that can run concurrently.
To avoid running out of PTT resources, too many PTT should not be
acquired without releasing them. Every PF has a global PTT, which is
used throughout the life of PF, in most important flows for register
access. Generic functions acquire the PTT locally and release after
the use. This patch aligns the use of Global PTT and Local PTT
accordingly.

net: Kernel side filtering for route dumps
Implement kernel side filtering of route dumps by protocol (e.g., which
routing daemon installed the route), route type (e.g., unicast), table
id and nexthop device.
iproute2 has been doing this filtering in userspace for years; pushing
the filters to the kernel side reduces the amount of data the kernel
sends and reduces wasted cycles on both sides processing unwanted data.
These initial options provide a huge improvement for efficiently
examining routes on large scale systems.
v2
- better handling of requests for a specific table. Rather than walking
the hash of all tables, lookup the specific table and dump it
- refactor mr_rtm_dumproute moving the loop over the table into a
helper that can be invoked directly
- add hook to return NLM_F_DUMP_FILTERED in DONE message to ensure
it is returned even when the dump returns nothing

This patch adds answer_flags to the netlink_callback allowing dump
handlers to set the NLM_F_DUMP_FILTERED at a minimum in the
NLMSG_DONE message ensuring the flag gets back to the user.
The netlink_callback space is initialized to 0 via a memset in

When TCP implements its own pacing (when no fq packet scheduler is used),
it is arming high resolution timer after a packet is sent.
But in many cases (like TCP_RR kind of workloads), this high resolution
timer expires before the application attempts to write the following
packet. This overhead also happens when the flow is ACK clocked and
cwnd limited instead of being limited by the pacing rate.
This leads to extra overhead (high number of IRQ)
Now tcp_wstamp_ns is reserved for the pacing timer only
(after commit "tcp: do not change tcp_wstamp_ns in tcp_mstamp_refresh"),
we can setup the timer only when a packet is about to be sent,
and if tcp_wstamp_ns is in the future.
This leads to a ~10% performance increase in TCP_RR workloads.

In commit fefa569a9d ("net_sched: sch_fq: account for schedule/timers
drifts") we added a mitigation for scheduling jitter in fq packet scheduler.
This patch does the same in TCP stack, now it is using EDT model.
Note that this mitigation is valid for both external (fq packet scheduler)
or internal TCP pacing.
This uses the same strategy than the above commit, allowing
a time credit of half the packet currently sent.
Consider following case :
An skb is sent, after an idle period of 300 usec.
The air-time (skb->len/pacing_rate) is 500 usec
Instead of setting the pacing timer to now+500 usec,
it will use now+min(500/2, 300) -> now+250usec
This is like having a token bucket with a depth of half
an skb.

sk_pacing_rate has beed introduced as a u32 field in 2013,
effectively limiting per flow pacing to 34Gbit.
We believe it is time to allow TCP to pace high speed flows
on 64bit hosts, as we now can reach 100Gbit on one TCP flow.
This patch adds no cost for 32bit kernels.
The tcpi_pacing_rate and tcpi_max_pacing_rate were already
exported as 64bit, so iproute2/ss command require no changes.
Unfortunately the SO_MAX_PACING_RATE socket option will stay
32bit and we will need to add a new option to let applications
control high pacing rates.

In EDT design, I made the mistake of using tcp_wstamp_ns
to store the last tcp_clock_ns() sample and to store the
pacing virtual timer.
This causes major regressions at high speed flows.
Introduce tcp_clock_cache to store last tcp_clock_ns().
This is needed because some arches have slow high-resolution
kernel time service.
tcp_wstamp_ns is only updated when a packet is sent.
Note that we can remove tcp_mstamp in the future since
tcp_mstamp is essentially tcp_clock_cache/1000, so the

bnxt_en: Add support for new 57500 chips.
This patch-set is larger than normal because I wanted a complete series
to add basic support for the new 57500 chips. The new chips have the
following main differences compared to legacy chips:
1. Requires the PF driver to allocate DMA context memory as a backing
store.
2. New NQ (notification queue) for interrupt events.
3. One or more CP rings can be associated with an NQ.
4. 64-bit doorbells.
Most other structures and firmware APIs are compatible with legacy
devices with some exceptions. For example, ring groups are no longer
used and RSS table format has changed.

and restructuring, and adding the new code to add basic support for the

Add a new poll function that polls for NQ events. If the NQ event is
a CQ notification, we locate the CP ring from the cq_handle and call
__bnxt_poll_work() to handle RX/TX events on the CP ring.
Add a new has_more_work field in struct bnxt_cp_ring_info to indicate
budget has been reached. __bnxt_poll_cqs_done() is called to update or
ARM the CP rings if budget has not been reached or not. If budget
has been reached, the next bnxt_poll_p5() call will continue to poll
from the CQ rings directly. Otherwise, the NQ will be ARMed for the
next IRQ.

Separate the CP ring polling logic in bnxt_poll_work() into 2 separate
functions __bnxt_poll_work() and __bnxt_poll_work_done(). Since the logic
is separated, we need to add tx_pkts and events fields to struct bnxt_napi
to keep track of the events to handle between the 2 functions. We also
add had_work_done field to struct bnxt_cp_ring_info to indicate whether
some work was performed on the CP ring.
This is needed to better support the 57500 chips. We need to poll up to
2 separate CP rings before we update or ARM the CP rings on the 57500 chips.

On legacy chips, the CP ring may be shared between RX and TX and so only

always have a dedicated CP ring for TX so we can always set up the
TX coalescing parameters in bnxt_hwrm_set_coal().
Also, the min_timer coalescing parameter applies to the NQ on the new
chips and a separate firmware call needs to be made to set it up.
