'ip' can switch network namespaces internally and then run a given
command relative to that namespace without the need to fork and exec
another ip instance. Update all references of the form:
ip netns exec "$testns" ip ...
to

git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/core
Pull perf/core improvements and fixes from Arnaldo Carvalho de Melo:
perf report:
He Kuang:
- Don't shadow inlined symbol with different addr range.
perf script:
Jiri Olsa:
- Allow +- operator to ask for -F to add/remove fields to
the default set, for instance to ask for the removal of the
'cpu' field in tracepoint events, adding 'period' to that
kind of events, etc.
perf test:
Thomas Richter:
- Fix scheduler tracepoint signedness of COMM fields failure of
'evsel-tp-sched' test on s390 and other arches.

perf trace:
Arnaldo Carvalho de Melo:
- Add initial BPF map dumper, initially just for the current, minimal
needs of the augmented_raw_syscalls BPF example used to collect
pointer args payloads that uses BPF maps for pid and syscall filtering,
but will in time have features similar to 'perf stat' --interval-print,
--interval-clear, ways to signal from a BPF event that a specific
map (or range of that map) should be printed, optionally as a
histogram, etc.
General:
Jiri Olsa:
- Add CPU and NUMA topologies classes for further reuse, fixing some
issues in the process.
- Fixup some warnings and debug levels.
- Make rm_rf() remove single file, not just directories.
Documentation:
Jonas Rabenstein:
- Fix HEADER_CMDLINE description in perf.data documentation.
- Fix documentation of the Flags section in perf.data.

Add a couple of new tests, explicitly checking that the kernel
timely releases PMTU exceptions on related device removal.
This is mostly a regression test vs the issue fixed by
commit f5b51fe804ec ("ipv6: route: purge exception on removal")
Only 2 new test cases have been added, instead of extending all
the existing ones, because the reproducer requires executing
several commands and would slow down too much the tests otherwise.
v2 -> v3:
- more cleanup, still from Stefano
v1 -> v2:
- several script cleanups, as suggested by Stefano

Otherwise, the configured IPv6 address could be still "tentative"
at test time, possibly causing tests failures.
We can also drop some sleep along the code and decrease the
timeout for most commands so that the test runtime decreases.

Also changes:

if (ret != NF_DROP && ret != NF_STOLEN &&

return ret;
everywhere.
The nat hooks never should return anything other than
ACCEPT or DROP (and the latter only in rare error cases).
The original code uses multi-line ANDing including assignment-in-if:
if (ret != NF_DROP && ret != NF_STOLEN &&
!(IPCB(skb)->flags & IPSKB_XFRM_TRANSFORMED) &&
(ct = nf_ct_get(skb, &ctinfo)) != NULL) {
I removed this while moving, breaking those in separate conditionals
and moving the assignments into extra lines.
checkpatch still generates some warnings:
1. Overly long lines (of moved code).
Breaking them is even more ugly. so I kept this as-is.
2. use of extern function declarations in a .c file.
This is necessary evil, we must call
nf_nat_l3proto_register() from the nat core now.
All l3proto related functions are removed later in this series,
those prototypes are then removed as well.
v2: keep empty nf_nat_ipv6_csum_update stub for CONFIG_IPV6=n case.
v3: remove IS_ENABLED(NF_NAT_IPV4/6) tests, NF_NAT_IPVx toggles

This commit adds AF_XDP support to libbpf. The main reason for this is
to facilitate writing applications that use AF_XDP by offering
higher-level APIs that hide many of the details of the AF_XDP
uapi. This is in the same vein as libbpf facilitates XDP adoption by
offering easy-to-use higher level interfaces of XDP
functionality. Hopefully this will facilitate adoption of AF_XDP, make
applications using it simpler and smaller, and finally also make it
possible for applications to benefit from optimizations in the AF_XDP
user space access code. Previously, people just copied and pasted the
code from the sample application into their application, which is not
desirable.
The interface is composed of two parts:
* Low-level access interface to the four rings and the packet
* High-level control plane interface for creating and setting
up umems and af_xdp sockets as well as a simple XDP program.

Simple test that I used to reproduce the issue in the previous commit:
Do BPF_PROG_TEST_RUN with max iterations, each program is 4096 simple
move instructions. File alarm in 0.1 second and check that
bpf_prog_test_run is interrupted (i.e. test doesn't hang).
Note: reposting this for bpf-next to avoid linux-next conflict. In this
version I test both BPF_PROG_TYPE_SOCKET_FILTER (which uses generic
bpf_test_run implementation) and BPF_PROG_TYPE_FLOW_DISSECTOR (which has
it own loop with preempt handling in bpf_prog_test_run_flow_dissector).

Implement test that verifies parallel rules insertion by adding 1 million
flower filters with 10 concurrent tc instances. Put it to standalone
'concurrency' category.
Implement tdc_multibatch.py helper script that is used to generate multiple
batch files for concurrent tc execution. Extend config with new 'BATCH_DIR'
variable to specify temporary output directory that is used to store batch
files generated by tdc_multibatch.py.

Extend tdc_batch.py with several optional CLI arguments that are used for
implementation of concurrency tests in following patches in this set:
- Add optional argument to specify range of filter handles used in batch
file [fitler_handle, filter_handle+number). This is needed for testing
filter deletion where it is necessary to know exact handles of configured
filters.
- Add optional argument to specify filter operation type (possible values
are ['add', 'del', 'replace']) instead of hardcoded "add" value. This
allows generation of batches for filter addition, deletion and
replacement.
- Add optional argument to allow user to change mac address prefix that is
used for all filters in batch. This is necessary to allow generating
multiple batches with unique flower classifier keys.

Three conflicts, one of which, for marvell10g.c is non-trivial and
requires some follow-up from Heiner or someone else.
The issue is that Heiner converted the marvell10g driver over to
use the generic c45 code as much as possible.
However, in 'net' a bug fix appeared which makes sure that a new
local mask (MDIO_AN_10GBT_CTRL_ADV_NBT_MASK) with value 0x01e0
is cleared.
