It should be possible to change the driver to not require this at
compile time and still provide other functions, but adding a hard
Kconfig dependency does not seem to have any practical downsides
and is simpler since the option is normally enabled anyway.

Booting the kernel with "maxcpus=1" is a common technique for CPU
partitioning and isolation. It delays the CPU bringup process until
when the bootup scripts are ready to bring CPUs online by writing 1 to
/sys/device/system/cpu/cpu<X>/online. However, it was found that not
all the CPUs were online after bootup. The collection of offline CPUs
are different after every reboot.
Further investigation reveals that some "online" write operations
fail with an -EBUSY error. This error is returned when CPU hotplug is
temporiarly disabled when cpu_hotplug_disable() is called.
During bootup, the main caller of cpu_hotplug_disable() is
pci_call_probe() for PCI device initialization. By measuring the times
spent with cpu_hotplug_disabled set in a typical 2-socket server, most
of them last less than 10ms. However, there are a few that can last
hundreds of ms. Note that the cpu_hotplug_disabled period of different
devices can overlap leading to longer cpu_hotplug_disabled hold time.
Since the CPU hotplug disable condition is transient and it is not
that easy to modify all the existing bootup scripts to handle this
condition, the kernel can help by retrying the online operation when
an -EBUSY error is returned. This patch retries the online operation
in cpu_subsys_online() when an -EBUSY error is returned for up to 5
times after an exponentially increasing delay that can last a total of
at least 620ms of waiting time by calling msleep().
With this patch in place, booting up the patched kernel with "maxcpus=1"
does not leave any CPU in an offline state in 10 reboot attempts.

Tweak some of the rule text to make things more straight forward, with
the goal to stick closely to the intend of the old text:
* put the "it or equivalent fix must be upstream" rule at the top, as
it's one of the most important ones that at the same time often seems
to be missed by developers.
* "It must fix only one thing" was dropped, as that is almost always a
thing that needs to be handled earlier when the change is mainlined.
Furthermore, this is already indirectly covered by the "Separate your
changes" section in Documentation/process/submitting-patches.rst which
the rules already point to.
* six other rules are in the end one rule with clarifications; structure
the text accordingly to make it a lot easier to follow and understand
the intend.
* drop the 'In short, something critical' from one of those notes: it
contradicts the "real bug that bothers people" aspect somewhat and does
not really add anything

Group some variables based on their sizes to reduce hole and avoid padding.
On x86_64, this shrinks the size of 'struct kobject' from 256 to 244 bytes.
This structure is often included in some other structures. So these other
structures will also benefit from this 8 bytes saving.
This is especially nice for structure like 'cma_kobject' or 'class_dir'
that are now 256 bytes long. When they are kzalloc()'ed, 256 bytes are
allocated, instead of 512.

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

* 36e68eadd3 : 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.

====================
mptcp: more fixes for v6.5
Here is a new batch of fixes related to MPTCP for v6.5 and older.
Patches 1 and 2 fix issues with MPTCP Join selftest when manually
launched with '-i' parameter to use 'ip mptcp' tool instead of the
dedicated one (pm_nl_ctl). The issues have been there since v5.18.
Thank you Andrea for your first contributions to MPTCP code in the
upstream kernel!
Patch 3 avoids corrupting the data stream when trying to reset
connections that have fallen back to TCP. This can happen from v6.1.
Patch 4 fixes a race when doing a disconnect() and an accept() in
parallel on a listener socket. The issue only happens in rare cases if
the user is really unlucky since a fix that landed in v6.3 but
backported up to v6.1.

Despite commit 0ad529d9fd ("mptcp: fix possible divide by zero in
recvmsg()"), the mptcp protocol is still prone to a race between
disconnect() (or shutdown) and accept.
The root cause is that the mentioned commit checks the msk-level
flag, but mptcp_stream_accept() does acquire the msk-level lock,
as it can rely directly on the first subflow lock.
As reported by Christoph than can lead to a race where an msk
socket is accepted after that mptcp_subflow_queue_clean() releases
the listener socket lock and just before it takes destructive
actions leading to the following splat:

Address the issue by temporary removing the pending request socket
from the accept queue, so that racing accept() can't touch them.
After depleting the msk - the ssk still exists, as plain TCP sockets,
re-insert them into the accept queue, so that later inet_csk_listen_stop()
will complete the tcp socket disposal.

This happens because of two reasons:
- iproute v6.3.0 does not support the implicit flag, fixed with
iproute2-next commit 3a2535a41854 ("mptcp: add support for implicit

- pm_nl_check_endpoint wrongly expects the ip address to be repeated two
times in iproute output, and does not account for a final whitespace
in it.
This fixes the issue trimming the whitespace in the output string and
removing the double address in the expected string.

This happens because endpoint delete includes an ip address while id is

"When used with the delete id operation, an IFADDR is only included when
the ID is 0."
This fixes the issue using the $addr variable in pm_nl_del_endpoint()

This was somewhat not so easy to spot, because "ocelot-8021q" is not the
default tagging protocol, and thus, not everyone who tests the unbinding
path may have switched to it beforehand. The default
felix_tag_npi_teardown() does not require rtnl_lock() to be held.
