While 3b52960266 ("test_bpf: add more eBPF jump torture cases")
added the int3 bug test case only for eBPF, which needs exactly 11
passes to converge, here's a version for classic BPF with 11 passes,
and one that would need 70 passes on x86_64 to actually converge for
being successfully JITed. Effectively, all jumps are being optimized
out resulting in a JIT image of just 89 bytes (from originally max
BPF insns), only returning K.
Might be useful as a receipe for folks wanting to craft a test case
when backporting the fix in commit 3f7352bf21 ("x86: bpf_jit: fix
compilation of large bpf programs") while not having eBPF. The 2nd
one is delegated to the interpreter as the last pass still results
in shrinking, in other words, this one won't be JITed on x86_64.

sfc: add MCDI tracing
This patchset adds support for logging MCDI (Management-Controller-to-
Driver Interface) interactions between the sfc driver and a bound device,
to aid in debugging.
Solarflare has a tool to decode the resulting traces and will look to
open-source this if there is any external interest, but the protocol is
already detailed in drivers/net/ethernet/sfc/mcdi_pcol.h.
The logging buffer we allocate per MCDI context is a work area for
constructing each individual message before logging it with netif_info.
The reason the buffer is long-lived is simply to avoid the overhead of
allocating and freeing it every MCDI call, since MCDIs are already known
to be serialised for other reasons.

As many issues are encountered at probe time, where MCDI logging can't be
enabled through the sysfs node, this change adds a module parameter
'mcdi_logging_default', which defaults to false. When set to true, newly-
probed functions will have MCDI logging enabled. The setting can
subsequently be changed as normal through the sysfs node.

MCDI tracing is conditional on CONFIG_SFC_MCDI_LOGGING, which is enabled

Each MCDI command will produce a console line like
sfc dom🚌dev:fn ifname: MCDI RPC REQ: xxxxxxxx [yyyyyyyy...]
where xxxxxxxx etc. are the raw MCDI payload in 32-bit hex chunks.
The response will then produce a similar line with "RESP" instead of "REQ",

A long standing problem on busy servers is the tiny available TCP port
range (/proc/sys/net/ipv4/ip_local_port_range) and the default
sequential allocation of source ports in connect() system call.
If a host is having a lot of active TCP sessions, chances are
very high that all ports are in use by at least one flow,
and subsequent bind(0) attempts fail, or have to scan a big portion of
space to find a slot.
In this patch, I changed the starting point in __inet_hash_connect()
so that we try to favor even [1] ports, leaving odd ports for bind()
users.
We still perform a sequential search, so there is no guarantee, but
if connect() targets are very different, end result is we leave
more ports available to bind(), and we spread them all over the range,
lowering time for both connect() and bind() to find a slot.
This strategy only works well if /proc/sys/net/ipv4/ip_local_port_range
is even, ie if start/end values have different parity.
Therefore, default /proc/sys/net/ipv4/ip_local_port_range was changed to
32768 - 60999 (instead of 32768 - 61000)
There is no change on security aspects here, only some poor hashing
schemes could be eventually impacted by this change.

====================
net: force refragmentation for DF reassembed skbs
output path tests:
if (skb->len > mtu) ip_fragment()
This breaks connectivity in one corner case:
If the skb was reassembled, but has the DF bit set and ..
.. its reassembled size is <= outdev mtu ..
.. we will forward a DF packet larger than what the sender
transmitted on wire.
If a router later in the path can't forward this packet, it will send an
icmp error in response to an mtu that the original sender never exceeded.
This changes ipv4 defrag/output path to
a) force refragmentation for DF reassembled skbs and
b) set DF bit on all fragments when refragmenting if it was set on original
frags.
tested via:
from scapy.all import *
dip="10.23.42.2"
payload="A"*1400
packet=IP(dst=dip,id=12345,flags='DF')/UDP(sport=42,dport=42)/payload
frags=fragment(packet,fragsize=1200)
for fragment in frags:
send(fragment)
Without this patch, we generate fragments without df bit set based
on the outgoing device mtu when fragmenting after forwarding, ie.
IP (ttl 64, id 12345, offset 0, flags [+, DF], proto UDP (17), length 1204)
192.168.7.1.42 > 10.23.42.2.42: UDP, length 1400
IP (ttl 64, id 12345, offset 1184, flags [DF], proto UDP (17), length 244)
192.168.7.1 > 10.23.42.2: ip-proto-17
on ingress will either turn into
IP (ttl 63, id 12345, offset 0, flags [+], proto UDP (17), length 1396)
192.168.7.1.42 > 10.23.42.2.42: UDP, length 1400
IP (ttl 63, id 12345, offset 1376, flags [none], proto UDP (17), length 52)
(mtu 1400: We strip df and send larger fragment), or
IP (ttl 63, id 12345, offset 0, flags [DF], proto UDP (17), length 1428)
192.168.7.1.42 > 10.23.42.2.42: [udp sum ok] UDP, length 1400
if mtu is 1500. And in this case things break; router with a smaller mtu
will send icmp error, but original sender only sent packets <= 1204 byte.
With patch, we keep intent of such fragments and will emit DF-fragments
that won't exceed 1204 byte in size.

We currently always send fragments without DF bit set.
Thus, given following setup:
mtu1500 - mtu1500:1400 - mtu1400:1280 - mtu1280
A R1 R2 B
Where R1 and R2 run linux with netfilter defragmentation/conntrack
enabled, then if Host A sent a fragmented packet _with_ DF set to B, R1
will respond with icmp too big error if one of these fragments exceeded
1400 bytes.
However, if R1 receives fragment sizes 1200 and 100, it would
forward the reassembled packet without refragmenting, i.e.
R2 will send an icmp error in response to a packet that was never sent,
citing mtu that the original sender never exceeded.
The other minor issue is that a refragmentation on R1 will conceal the
MTU of R2-B since refragmentation does not set DF bit on the fragments.
This modifies ip_fragment so that we track largest fragment size seen
both for DF and non-DF packets, and set frag_max_size to the largest
value.
If the DF fragment size is larger or equal to the non-df one, we will
consider the packet a path mtu probe:
We set DF bit on the reassembled skb and also tag it with a new IPCB flag
to force refragmentation even if skb fits outdev mtu.
We will also set DF bit on each fragment in this case.

In commit dd3f9e70f5
("tipc: add packet sequence number at instant of transmission") we
made a change with the consequence that packets in the link backlog
queue don't contain valid sequence numbers.
However, when we create a link protocol message, we still use the
sequence number of the first packet in the backlog, if there is any,
as "next_sent" indicator in the message. This may entail unnecessary
retransissions or stale packet transmission when there is very low
traffic on the link.
This commit fixes this issue by only using the current value of
tipc_link::snd_nxt as indicator.

When we disconnect from the AP, drivers call cfg80211_disconnect().
This doesn't know whether the disconnection was initiated locally
or by the AP though, which can cause problems with the supplicant,
for example with WPS. This issue obviously doesn't show up with any
mac80211 based driver since mac80211 doesn't call this function.
Fix this by requiring drivers to indicate whether the disconnect is
locally generated or not. I've tried to update the drivers, but may
not have gotten the values correct, and some drivers may currently
not be able to report correct values. In case of doubt I left it at
false, which is the current behaviour.

The second patch depends on the first though it could be rebased.
I had previously asked for v2 to be put on hold while some bugs I had found
in the rocker driver were shaken out. That has now happened and the bugs
turned out to be unrelated. Accordingly I am reposting the series.
* Changes v2 -> v3
- Rebase and update for new variables and parameters that may be const
* Changes v1 -> v2
- Found quite a few more variables and parameters to make const

Mark parameters and local variables as const where possible.
