Some protocols have other means to verify the payload integrity
(AH, ESP, SCTP) while others are incompatible with nf_ip(6)_checksum
implementation because checksum is either optional or might be
partial (UDPLITE, DCCP, GRE). Because nf_ip(6)_checksum was used
to validate the packets, ip(6)tables REJECT rules were not capable
to generate ICMP(v6) errors for the protocols mentioned above.

This commit also fixes the incorrect pseudo-header protocol used
for IPv4 packets that carry other transport protocols than TCP or
UDP (pseudo-header used protocol 0 iso the proper value).

For bridge(br_flood) or broadcast/multicast packets, they could clone
skb with unconfirmed conntrack which break the rule that unconfirmed
skb->_nfct is never shared.  With nfqueue running on my system, the race
can be easily reproduced with following warning calltrace:

  // skb->_nfct (unconfirmed conntrack) is constructed at PRE_ROUTING stage
  br_handle_frame_finish

    br_pass_frame_up
      BR_HOOK(NFPROTO_BRIDGE, NF_BR_LOCAL_IN,...)
      // goto __nf_conntrack_confirm with softirq context on CPU 0

Because conntrack confirm can happen at both INPUT and POSTROUTING
stage.  So with NFQUEUE running, skb->_nfct with the same unconfirmed
conntrack could race on different core.

One of the more common cases of allocation size calculations is finding
the size of a structure that has a zero-sized array at the end, along
with memory for some number of elements for that array. For example:

struct foo {
    int stuff;
    void *entry[];
};

size = sizeof(struct foo) + count * sizeof(void *);
instance = alloc(size, GFP_KERNEL)

Instead of leaving these open-coded and prone to type mistakes, we can
now use the new struct_size() helper:

size = struct_size(instance, entry, count);
instance = alloc(size, GFP_KERNEL)

Notice that, in this case, variable sz is not necessary, hence it is

pull-request: bpf-next 2019-01-29

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

The main changes are:

1) Teach verifier dead code removal, this also allows for optimizing /
   removing conditional branches around dead code and to shrink the
   resulting image. Code store constrained architectures like nfp would
   have hard time doing this at JIT level, from Jakub.

2) Add JMP32 instructions to BPF ISA in order to allow for optimizing
   code generation for 32-bit sub-registers. Evaluation shows that this
   can result in code reduction of ~5-20% compared to 64 bit-only code
   generation. Also add implementation for most JITs, from Jiong.

3) Add support for __int128 types in BTF which is also needed for
   vmlinux's BTF conversion to work, from Yonghong.

4) Add a new command to bpftool in order to dump a list of BPF-related
   parameters from the system or for a specific network device e.g. in
   terms of available prog/map types or helper functions, from Quentin.

5) Add AF_XDP sock_diag interface for querying sockets from user
   space which provides information about the RX/TX/fill/completion
   rings, umem, memory usage etc, from Björn.

6) Add skb context access for skb_shared_info->gso_segs field, from Eric.

7) Add support for testing flow dissector BPF programs by extending
   existing BPF_PROG_TEST_RUN infrastructure, from Stanislav.

8) Split BPF kselftest's test_verifier into various subgroups of tests
   in order better deal with merge conflicts in this area, from Jakub.

9) Add support for queue/stack manipulations in bpftool, from Stanislav.

10) Document BTF, from Yonghong.

11) Dump supported ELF section names in libbpf on program load
    failure, from Taeung.

12) Silence a false positive compiler warning in verifier's BTF
    handling, from Peter.

13) Fix help string in bpftool's feature probing, from Prashant.

14) Remove duplicate includes in BPF kselftests, from Yue.

4) Call request_module() to autoload br_netfilter when physdev is used

10) Unify sysctl handling at the core of nf_conntrack, from Florian.

11) Provide modparam to register conntrack hooks.

12) Allow to match on the interface kind string, from wenxu.

13) Remove several exported symbols, not required anymore now after

14) Remove built-in map support in the hash extension, this can be

a packet as an input and `struct bpf_flow_key' as an output. That way
we can easily test flow dissector programs' behavior. I've also modified
existing test_progs.c test to do a simple flow dissector run as well.

* first patch introduces new __skb_flow_bpf_dissect to simplify
  sharing between __skb_flow_bpf_dissect and BPF_PROG_TEST_RUN
* second patch adds actual BPF_PROG_TEST_RUN support
* third patch adds example usage to the selftests

When prog array is updated with bpftool users often refer
to the map via the ID.  Unfortunately, that's likely
to lead to confusion because prog arrays get flushed when
the last user reference is gone.  If there is no other
reference bpftool will create one, update successfully
just to close the map again and have it flushed.

Warn about this case in non-JSON mode.

If the problem continues causing confusion we can remove
the support for referring to a map by ID for prog array
update completely.  For now it seems like the potential
inconvenience to users who know what they're doing outweighs
the benefit.

qed*: Error recovery process

Parity errors might happen in the device's memories due to momentary bit
flips which are caused by radiation.
Errors that are not correctable initiate a process kill event, which blocks
the device access towards the host and the network, and a recovery process
is started in the management FW and in the driver.

This series adds the support of this process in the qed core module and in
the qede driver (patches 2 & 3).

====================
The tools/testing/selftests/bpf/test_verifier.c file is
way too large, and since most people add their at the
end of the list it's very prone to conflicts.

Break it up in the simplest possible way - slice the
array up into smaller C files and include them in the
right spot.

Tested:
$ make -C tools/testing/selftests/bpf/
$ cd tools/testing/selftests/bpf/ ; make

v2:

The indentation is reduced further as discussed and lines folded.
The conversion was scripted, and double checked by hand.

Break up the rest of test_verifier tests into separate
files.

Break up the first 10 kLoC of test verifier test cases
out into smaller files.  Looks like git line counting
gets a little flismy above 16 bit integers, so we need
two commits to break up test_verifier.
