031c99e71f selftests: tc: add ConnTrack procfs kconfig
When looking at the TC selftest reports, I noticed one test was failing
because /proc/net/nf_conntrack was not available.

  not ok 373 3992 - Add ct action triggering DNAT tuple conflict
  	Could not match regex pattern. Verify command output:
  cat: /proc/net/nf_conntrack: No such file or directory

It is only available if NF_CONNTRACK_PROCFS kconfig is set. So the issue
can be fixed simply by adding it to the list of required kconfig.

719b4774a8 selftests: tc: add 'ct' action kconfig dep
When looking for something else in LKFT reports [1], I noticed most of
the tests were skipped because the "teardown stage" did not complete
successfully.

Pedro found out this is due to the fact CONFIG_NF_FLOW_TABLE is required
but not listed in the 'config' file. Adding it to the list fixes the
issues on LKFT side. CONFIG_NET_ACT_CT is now set to 'm' in the final
kconfig.

fda05798c2 selftests: tc: set timeout to 15 minutes
When looking for something else in LKFT reports [1], I noticed that the
TC selftest ended with a timeout error:

  not ok 1 selftests: tc-testing: tdc.sh # TIMEOUT 45 seconds

The timeout had been introduced 3 years ago, see the Fixes commit below.

This timeout is only in place when executing the selftests via the
kselftests runner scripts. I guess this is not what most TC devs are
using and nobody noticed the issue before.

The new timeout is set to 15 minutes as suggested by Pedro [2]. It looks
like it is plenty more time than what it takes in "normal" conditions.

the actual value will be set to 12ms which causes the test to fail:

 # Test 3410: Create SFB with db setting

Set the value to 100ms instead which currently seem to work on 100hz,
250hz, 300hz and 1000hz kernel configs.

7041101ff6 net/sched: sch_fq: fix integer overflow of "credit"
if sch_fq is configured with "initial quantum" having values greater than
INT_MAX, the first assignment of "credit" does signed integer overflow to
a very negative value.
In this situation, the syzkaller script provided by Cristoph triggers the
CPU soft-lockup warning even with few sockets. It's not an infinite loop,
but "credit" wasn't probably meant to be minus 2Gb for each new flow.
Capping "initial quantum" to INT_MAX proved to fix the issue.

v2: validation of "initial quantum" is done in fq_policy, instead of open
    coding in fq_change() _ suggested by Jakub Kicinski

7f3f864026 selftests: tc-testing: add "depends_on" property to skip tests
currently, users can skip individual test cases by means of writing

  "skip": "yes"

in the scenario file. Extend this functionality, introducing 'dependsOn':
it's optional property like "skip", but the value contains a command (for
example, a probe on iproute2 to check if it supports a specific feature).
If such property is present, tdc executes that command and skips the test
when the return value is non-zero.

It has become mostly a shooting target for syzkaller lately.

95d9a3dab1 selftests: tc-testing: Add matchJSON to tdc
This allows the use of a matchJSON field in tests to match
against JSON output from the command under test, if that
command outputs JSON.

You specify what you want to match against as a JSON array
or object in the test's matchJSON field. You can leave out
any fields you don't want to match against that are present
in the output and they will be skipped.

An example matchJSON value would look like this:

"matchJSON": [
  {
    "Value": {
      "neighIP": {
        "family": 4,
        "addr": "AQIDBA==",
        "width": 32
      },
      "nsflags": 142,
      "ncflags": 0,
      "LLADDR": "ESIzRFVm"
    }
  }
]

The real output from the command under test might have some
extra fields that we don't care about for matching, and
since we didn't include them in our matchJSON value, those
fields will not be attempted to be matched. If everything
we included above has the same values as the real command
output, the test will pass.

The matchJSON field's type must be the same as the command
output's type, otherwise the test will fail. So if the
command outputs an array, then the value of matchJSON must
also be an array.

If matchJSON is an array, it must not contain more elements
than the command output's array, otherwise the test will
fail.

    and IP multicast router.
 
  - Network-side support for IO uring zero-copy send.
 
  - A few skb drop reason improvements, including codegen the source file
    with string mapping instead of using macro magic.
 
  - Rename reference tracking helpers to a more consistent
    netdev_* schema.
 
  - Adapt u64_stats_t type to address load/store tearing issues.
 
  - Refine debug helper usage to reduce the log noise caused by bots.
 
 BPF
 ---

f2745dc0ba selftests: stop using KSFT_KHDR_INSTALL
Stop using the KSFT_KHDR_INSTALL flag as installing the kernel headers
from the kselftest Makefile is causing some issues.  Instead, rely on
the headers to be installed directly by the top-level Makefile
"headers_install" make target prior to building kselftest.

The missing entry is because the 2nd packet hits a tuple collusion and the

3a62fed2fd net/sched: fq_pie: re-factor fix for fq_pie endless loop
the patch that fixed an endless loop in_fq_pie_init() was not considering
that 65535 is a valid class id. The correct bugfix for this infinite loop
is to change 'idx' to become an u32, like Colin proposed in the past [1].

Fix this as follows:
 - restore 65536 as maximum possible values of 'flows_cnt'
 - use u32 'idx' when iterating on 'q->flows'
 - fix the TDC selftest

This reverts commit bb2f930d6d.

e48792a9ec tc-testing: add simple action change test
Use act_simple to verify that action created with 'tc actions change'
command exists after command returns. The goal is to verify internal action
API reference counting to ensure that the case when netlink message has
NLM_F_REPLACE flag set but action with specified index doesn't exist is
handled correctly.

Daniel Borkmann says:

====================
pull-request: bpf-next 2021-02-16

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

There's a small merge conflict between 7eeba1706e ("tcp: Add receive timestamp
support for receive zerocopy.") from net-next tree and 9cacf81f81 ("bpf: Remove
extra lock_sock for TCP_ZEROCOPY_RECEIVE") from bpf-next tree. Resolve as follows:

  [...]
                lock_sock(sk);
                err = tcp_zerocopy_receive(sk, &zc, &tss);
                err = BPF_CGROUP_RUN_PROG_GETSOCKOPT_KERN(sk, level, optname,
                                                          &zc, &len, err);
                release_sock(sk);
  [...]

We've added 116 non-merge commits during the last 27 day(s) which contain
a total of 156 files changed, 5662 insertions(+), 1489 deletions(-).

The main changes are:

1) Adds support of pointers to types with known size among global function
   args to overcome the limit on max # of allowed args, from Dmitrii Banshchikov.

2) Add bpf_iter for task_vma which can be used to generate information similar
   to /proc/pid/maps, from Song Liu.

3) Enable bpf_{g,s}etsockopt() from all sock_addr related program hooks. Allow
   rewriting bind user ports from BPF side below the ip_unprivileged_port_start
   range, both from Stanislav Fomichev.

4) Prevent recursion on fentry/fexit & sleepable programs and allow map-in-map
   as well as per-cpu maps for the latter, from Alexei Starovoitov.

5) Add selftest script to run BPF CI locally. Also enable BPF ringbuffer
   for sleepable programs, both from KP Singh.

6) Extend verifier to enable variable offset read/write access to the BPF
   program stack, from Andrei Matei.

7) Improve tc & XDP MTU handling and add a new bpf_check_mtu() helper to
   query device MTU from programs, from Jesper Dangaard Brouer.

8) Allow bpf_get_socket_cookie() helper also be called from [sleepable] BPF
   tracing programs, from Florent Revest.

9) Extend x86 JIT to pad JMPs with NOPs for helping image to converge when
   otherwise too many passes are required, from Gary Lin.

10) Verifier fixes on atomics with BPF_FETCH as well as function-by-function
    verification both related to zero-extension handling, from Ilya Leoshkevich.

11) Better kernel build integration of resolve_btfids tool, from Jiri Olsa.

12) Batch of AF_XDP selftest cleanups and small performance improvement
    for libbpf's xsk map redirect for newer kernels, from Björn Töpel.

13) Follow-up BPF doc and verifier improvements around atomics with
    BPF_FETCH, from Brendan Jackman.

14) Permit zero-sized data sections e.g. if ELF .rodata section contains
    read-only data from local variables, from Yonghong Song.

15) veth driver skb bulk-allocation for ndo_xdp_xmit, from Lorenzo Bianconi.
