Pull networking updates from David Miller:

1) New ipset extensions for matching on destination MAC addresses, from
Stefano Brivio.

2) Add ipv4 ttl and tos, plus ipv6 flow label and hop limit offloads to
nfp driver. From Stefano Brivio.

3) Implement GRO for plain UDP sockets, from Paolo Abeni.

4) Lots of work from Michał Mirosław to eliminate the VLAN_TAG_PRESENT
bit so that we could support the entire vlan_tci value.

5) Rework the IPSEC policy lookups to better optimize more usecases,
from Florian Westphal.

6) Infrastructure changes eliminating direct manipulation of SKB lists
wherever possible, and to always use the appropriate SKB list
helpers. This work is still ongoing...

simplifications, from Heiner Kallweit.

8) Various TSO deferral refinements, from Eric Dumazet.

9) Add ntuple filter support to aquantia driver, from Dmitry Bogdanov.

10) Batch dropping of XDP packets in tuntap, from Jason Wang.

11) Lots of cleanups and improvements to the r8169 driver from Heiner
Kallweit, including support for ->xmit_more. This driver has been

21) Remove egdev usage from nfp and mlx5, and remove the facility
completely from the tree as it no longer has any users. From Oz
Shlomo and others.

22) Add a NETDEV_PRE_CHANGEADDR so that drivers can veto the change and
therefore abort the operation before the commit phase (which is the
NETDEV_CHANGEADDR event). From Petr Machata.

in the GRO code paths. From Paolo Abeni.

24) Add support for netlink FDB get operations, from Roopa Prabhu.

25) Support bloom filter in mlxsw driver, from Nir Dotan.

26) Add SKB extension infrastructure. This consolidates the handling of
the auxiliary SKB data used by IPSEC and bridge netfilter, and is
designed to support the needs to MPTCP which could be integrated in
the future.

27) Lots of XDP TX optimizations in mlx5 from Tariq Toukan.

The following pull-request contains BPF updates for your *net-next* tree.

The main changes are:

1) Extend BTF to support function call types and improve the BPF
symbol handling with this info for kallsyms and bpftool program
dump to make debugging easier, from Martin and Yonghong.

2) Optimize LPM lookups by making longest_prefix_match() handle
multiple bytes at a time, from Eric.

3) Adds support for loading and attaching flow dissector BPF progs
from bpftool, from Stanislav.

4) Extend the sk_lookup() helper to be supported from XDP, from Nitin.

5) Enable verifier to support narrow context loads with offset > 0
to adapt to LLVM code generation (currently only offset of 0 was
supported). Add test cases as well, from Andrey.

6) Simplify passing device functions for offloaded BPF progs by
adding callbacks to bpf_prog_offload_ops instead of ndo_bpf.
Also convert nfp and netdevsim to make use of them, from Quentin.

7) Add support for sock_ops based BPF programs to send events to
the perf ring-buffer through perf_event_output helper, from
Sowmini and Daniel.

8) Add read / write support for skb->tstamp from tc BPF and cg BPF
programs to allow for supporting rate-limiting in EDT qdiscs
like fq from BPF side, from Vlad.

9) Extend libbpf API to support map in map types and add test cases
for it as well to BPF kselftests, from Nikita.

10) Account the maximum packet offset accessed by a BPF program in
the verifier and use it for optimizing nfp JIT, from Jiong.

11) Fix error handling regarding kprobe_events in BPF sample loader,
from Daniel T.

12) Add support for queue and stack map type in bpftool, from David.

Merge branch 'btf-func-info'

Martin KaFai Lau says:

====================
The BTF support was added to kernel by Commit 69b693f0aefa
("bpf: btf: Introduce BPF Type Format (BTF)"), which introduced
.BTF section into ELF file and is primarily
used for map pretty print.
pahole is used to convert dwarf to BTF for ELF files.

This patch added func info support to the kernel so we can
get better ksym's for bpf function calls. Basically,
function call types are passed to kernel and the kernel
extract function names from these types in order to contruct ksym
for these functions.

The llvm patch at https://reviews.llvm.org/D53736
will generate .BTF section and one more section .BTF.ext.
The .BTF.ext section encodes function type
information. The following is a sample output for selftests
test_btf with file test_btf_haskv.o for translated insns
and jited insns respectively.

Changelogs:
v4 -> v5:
. Add back BTF_KIND_FUNC_PROTO as v1 did. The difference
is BTF_KIND_FUNC_PROTO cannot have t->name_off now.
All param metadata is defined in BTF_KIND_FUNC_PROTO.
BTF_KIND_FUNC must have t->name_off != 0 and t->type
refers to a BTF_KIND_FUNC_PROTO.

The above is the conclusion after the discussion between
Edward Cree, Alexei, Daniel, Yonghong and Martin.
v3 -> v4:
. Remove BTF_KIND_FUNC_PROTO. BTF_KIND_FUNC is used for
both function pointer and subprogram. The name_off field
is used to distinguish both.
. The record size is added to the func_info subsection
in .BTF.ext to enable future extension.
. The bpf_prog_info interface change to make it similar
bpf_prog_load.
. Related kernel and libbpf changes to accommodate the
new .BTF.ext and kernel interface changes.
v2 -> v3:
. Removed kernel btf extern functions btf_type_id_func()
and btf_get_name_by_id(). Instead, exposing existing
functions btf_type_by_id() and btf_name_by_offset().
. Added comments about ELF section .BTF.ext layout.
. Better codes in btftool as suggested by Edward Cree.
v1 -> v2:
. Added missing sign-off.
. Limited the func_name/struct_member_name length for validity test.
. Removed/changed several verifier messages.
. Modified several commit messages to remove line_off reference.

Merge tag 'y2038' of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/playground into timers/core

Pull more y2038 work from Arnd Bergman:

y2038: convert more syscalls

Here is another set of system call changes to prepare the change over to
64-bit time_t. As before, the strategy is to change system calls that
take a 'struct timespec' argument over to 'struct __kernel_timespec',
which for now is defined to be the same but will get redefined to use a
64-bit time_t argument once we are ready to modify the system call tables.

The major change from previous patches is that the plan is no longer
to directly use the 'compat' system calls for providing compatibility
with the existing 32-bit time_t based entry points. Instead, we rename
the compat code to something that makes more sense on 32-bit architectures,
e.g. compat_timespec becomes old_timespec32.

With the renamed types in place, change over the 'stat' and 'utimes'
families of system calls, sched_rr_get_interval, recvmmsg and
rt_sigtimedwait. Another series for poll, select and io_pgetevents is
currently being tested.
