It cannot overlap with the local port range - ie. with autobind selectable
ports - and not with reserved ports.
Indeed 'ip_local_reserved_ports' isn't even a range, it's a (by default
empty) set.

There are no users of phy_ethtool_sset() in the kernel anymore, and
as of commit 3c1bcc8614db ("net: ethernet: Convert phydev advertize
and supported from u32 to link mode"), the implementation is slightly
buggy - it doesn't correctly check the masked advertising mask as it
used to.
Remove it, and update the phy documentation to refer to its replacement
function.

The main changes are:
1) Addition of BPF trampoline which works as a bridge between kernel functions,
BPF programs and other BPF programs along with two new use cases: i) fentry/fexit
BPF programs for tracing with practically zero overhead to call into BPF (as
opposed to k[ret]probes) and ii) attachment of the former to networking related
programs to see input/output of networking programs (covering xdpdump use case),
from Alexei Starovoitov.
2) BPF array map mmap support and use in libbpf for global data maps; also a big
batch of libbpf improvements, among others, support for reading bitfields in a
relocatable manner (via libbpf's CO-RE helper API), from Andrii Nakryiko.
3) Extend s390x JIT with usage of relative long jumps and loads in order to lift
the current 64/512k size limits on JITed BPF programs there, from Ilya Leoshkevich.
4) Add BPF audit support and emit messages upon successful prog load and unload in
order to have a timeline of events, from Daniel Borkmann and Jiri Olsa.
5) Extension to libbpf and xdpsock sample programs to demo the shared umem mode
(XDP_SHARED_UMEM) as well as RX-only and TX-only sockets, from Magnus Karlsson.
6) Several follow-up bug fixes for libbpf's auto-pinning code and a new API
call named bpf_get_link_xdp_info() for retrieving the full set of prog
IDs attached to XDP, from Toke Høiland-Jørgensen.
7) Add BTF support for array of int, array of struct and multidimensional arrays
and enable it for skb->cb[] access in kfree_skb test, from Martin KaFai Lau.
8) Fix AF_XDP by using the correct number of channels from ethtool, from Luigi Rizzo.

This is a new feature defined in section 5 of rfc7829: "Primary Path
Switchover". By introducing a new tunable parameter:
Primary.Switchover.Max.Retrans (PSMR)
The primary path will be changed to another active path when the path
error counter on the old primary path exceeds PSMR, so that "the SCTP
sender is allowed to continue data transmission on a new working path
even when the old primary destination address becomes active again".
This patch is to add this tunable parameter, 'ps_retrans' per netns,
sock, asoc and transport. It also allows a user to change ps_retrans
per netns by sysctl, and ps_retrans per sock/asoc/transport will be
initialized with it.
The check will be done in sctp_do_8_2_transport_strike() when this
feature is enabled.
Note this feature is disabled by initializing 'ps_retrans' per netns
as 0xffff by default, and its value can't be less than 'pf_retrans'
when changing by sysctl.
v3->v4:
- add define SCTP_PS_RETRANS_MAX 0xffff, and use it on extra2 of
sysctl 'ps_retrans'.
- add a new entry for ps_retrans on ip-sysctl.txt.

As said in rfc7829, section 3, point 12:
The SCTP stack SHOULD expose the PF state of its destination
addresses to the ULP as well as provide the means to notify the
ULP of state transitions of its destination addresses from
active to PF, and vice versa. However, it is recommended that
an SCTP stack implementing SCTP-PF also allows for the ULP to be
kept ignorant of the PF state of its destinations and the
associated state transitions, thus allowing for retention of the
simpler state transition model of [RFC4960] in the ULP.
Not only does it allow to expose the PF state to ULP, but also
allow to ignore sctp-pf to ULP.
So this patch is to add pf_expose per netns, sock and asoc. And in
sctp_assoc_control_transport(), ulp_notify will be set to false if
asoc->expose is not 'enabled' in next patch.
It also allows a user to change pf_expose per netns by sysctl, and
pf_expose per sock and asoc will be initialized with it.
Note that pf_expose also works for SCTP_GET_PEER_ADDR_INFO sockopt,
to not allow a user to query the state of a sctp-pf peer address
when pf_expose is 'disabled', as said in section 7.3.
v1->v2:
- Fix a build warning noticed by Nathan Chancellor.
v2->v3:
- set pf_expose to UNUSED by default to keep compatible with old
applications.
v3->v4:
- add a new entry for pf_expose on ip-sysctl.txt, as Marcelo suggested.
- change this patch to 1/5, and move sctp_assoc_control_transport
change into 2/5, as Marcelo suggested.
- use SCTP_PF_EXPOSE_UNSET instead of SCTP_PF_EXPOSE_UNUSED, and
set SCTP_PF_EXPOSE_UNSET to 0 in enum, as Marcelo suggested.

atlantic hardware does support UDP hardware segmentation offload.
This allows user to specify one large contiguous buffer with data
which then will be split automagically into multiple UDP packets
of specified size.
Bulk sending of large UDP streams lowers CPU usage and increases
bandwidth.

Unlike drop traps, these exception traps also need to inject the packet
to the kernel's receive path. For example, a packet that was trapped due
to unreachable neighbour need to be injected into the kernel so that it
will trigger an ARP request or a neighbour solicitation message.

Intel Wired LAN Driver Updates 2019-11-01
This series contains updates to e1000, igb, igc, ixgbe, i40e and driver
documentation.
Lyude Paul fixes an issue where a fatal read error occurs when the
device is unplugged from the machine. So change the read error into a
warn while the device is still present.
Manfred Rudigier found that the i350 device was not apart of the "Media
Auto Sense" feature, yet the device supports it. So add the missing
i350 device to the check and fix an issue where the media auto sense
would flip/flop when no cable was connected to the port causing spurious
kernel log messages.
I fixed an issue where the fix to resolve receive buffer starvation was
applied in more than one place in the driver, one being the incorrect
location in the i40e driver.
Wenwen Wang fixes a potential memory leak in e1000 where allocated
memory is not properly cleaned up in one of the error paths.
Jonathan Neuschäfer cleans up the driver documentation to be consistent
and remove the footnote reference, since the footnote no longer exists in
the documentation.
Igor Pylypiv cleans up a duplicate clearing of a bit, no need to clear
it twice.
v2: Fixed alignment issue in patch 3 of the series based on community
feedback.

SOMAXCONN is /proc/sys/net/core/somaxconn default value.
It has been defined as 128 more than 20 years ago.
Since it caps the listen() backlog values, the very small value has
caused numerous problems over the years, and many people had
to raise it on their hosts after beeing hit by problems.
Google has been using 1024 for at least 15 years, and we increased
this to 4096 after TCP listener rework has been completed, more than
4 years ago. We got no complain of this change breaking any
legacy application.
Many applications indeed setup a TCP listener with listen(fd, -1);
meaning they let the system select the backlog.
Raising SOMAXCONN lowers chance of the port being unavailable under
even small SYNFLOOD attack, and reduces possibilities of side channel
vulnerabilities.

The following pull-request contains BPF updates for your *net-next* tree.
We've added 52 non-merge commits during the last 11 day(s) which contain
a total of 65 files changed, 2604 insertions(+), 1100 deletions(-).
The main changes are:
1) Revolutionize BPF tracing by using in-kernel BTF to type check BPF
assembly code. The work here teaches BPF verifier to recognize
kfree_skb()'s first argument as 'struct sk_buff *' in tracepoints
such that verifier allows direct use of bpf_skb_event_output() helper
used in tc BPF et al (w/o probing memory access) that dumps skb data
into perf ring buffer. Also add direct loads to probe memory in order
to speed up/replace bpf_probe_read() calls, from Alexei Starovoitov.
2) Big batch of changes to improve libbpf and BPF kselftests. Besides
others: generalization of libbpf's CO-RE relocation support to now
also include field existence relocations, revamp the BPF kselftest
Makefile to add test runner concept allowing to exercise various
ways to build BPF programs, and teach bpf_object__open() and friends
to automatically derive BPF program type/expected attach type from
section names to ease their use, from Andrii Nakryiko.
3) Fix deadlock in stackmap's build-id lookup on rq_lock(), from Song Liu.
4) Allow to read BTF as raw data from bpftool. Most notable use case
is to dump /sys/kernel/btf/vmlinux through this, from Jiri Olsa.
5) Use bpf_redirect_map() helper in libbpf's AF_XDP helper prog which
manages to improve "rx_drop" performance by ~4%., from Björn Töpel.
6) Fix to restore the flow dissector after reattach BPF test and also
fix error handling in bpf_helper_defs.h generation, from Jakub Sitnicki.
7) Improve verifier's BTF ctx access for use outside of raw_tp, from
Martin KaFai Lau.
8) Improve documentation for AF_XDP with new sections and to reflect
latest features, from Magnus Karlsson.
9) Add back 'version' section parsing to libbpf for old kernels, from
John Fastabend.
10) Fix strncat bounds error in libbpf's libbpf_prog_type_by_name(),
from KP Singh.
11) Turn on -mattr=+alu32 in LLVM by default for BPF kselftests in order
to improve insn coverage for built BPF progs, from Yonghong Song.
