The function do_test_span_vlan_dir_ips() is used for testing whether
mirrored packets are VLAN-encapsulated. But since it only considers
VLAN encapsulation, it may end up matching unmirrored ARP traffic as
well. One consequence is a rare failure of mirror_gre_vlan_bridge_1q's
test_gretap_untagged_egress. Decreasing ping cadence in mirror_test()
makes the problem easily reproducible.
Therefore tighten up the match criterion to only count those 802.1q
packets where the next header is IP.

Declaring the rseq_cs field as a union between __u64 and two __u32
allows both 32-bit and 64-bit kernels to read the full __u64, and
therefore validate that a 32-bit user-space cleared the upper 32
bits, thus ensuring a consistent behavior between native 32-bit
kernels and 32-bit compat tasks on 64-bit kernels.
Check that the rseq_cs value read is < TASK_SIZE.
The asm/byteorder.h header needs to be included by rseq.h, now
that it is not using linux/types_32_64.h anymore.
Considering that only __32 and __u64 types are declared in linux/rseq.h,
the linux/types.h header should always be included for both kernel and
user-space code: including stdint.h is just for u64 and u32, which are
not used in this header at all.
Use copy_from_user()/clear_user() to interact with a 64-bit field,
because arm32 does not implement 64-bit __get_user, and ppc32 does not
64-bit get_user. Considering that the rseq_cs pointer does not need to
be loaded/stored with single-copy atomicity from the kernel anymore, we
can simply use copy_from_user()/clear_user().

The next patch introduces a new mlxsw-specific test that uses
mirror_gre_lib.sh and mirror_gre_topo_lib.sh.
However when sourcing their own deps, these libraries assume that the
test that's running is in the same directory. That's not the case for
driver-specific tests.
So change the libraries to source their deps through $relative_path.
That variable is set up by lib.sh, which should be imported by the test
in question in any case.

This commit introduces a new bpftool command: cgroup tree.
The idea is to iterate over the whole cgroup tree and print
all attached programs.
I was debugging a bpf/systemd issue, and found, that there is
no simple way to listen all bpf programs attached to cgroups.
I did master something in bash, but after some time got tired of it,
and decided, that adding a dedicated bpftool command could be
a better idea.
So, here it is:
$ sudo ./bpftool cgroup tree
CgroupPath
ID AttachType AttachFlags Name
/sys/fs/cgroup/system.slice/systemd-machined.service
18 ingress
17 egress
/sys/fs/cgroup/system.slice/systemd-logind.service

Since the following commit:
cd77849a69cf ("objtool: Fix GCC 8 cold subfunction detection for aliased functions")
... if the kernel is built with EXTRA_CFLAGS='-fno-reorder-functions',
objtool can get stuck in an infinite loop.
That flag causes the new GCC 8 cold subfunctions to be placed in .text
instead of .text.unlikely. But it also has an unfortunate quirk: in the
symbol table, the subfunction (e.g., nmi_panic.cold.7) is nested inside
the parent (nmi_panic).
That function overlap confuses objtool, and causes it to get into an
infinite loop in next_insn_same_func(). Here's Allan's description of
the loop:
"Objtool iterates through the instructions in nmi_panic using
next_insn_same_func. Once it reaches the end of nmi_panic at 0x534 it
jumps to 0x528 as that's the start of nmi_panic.cold.7. However, since
the instructions starting at 0x528 are still associated with nmi_panic
objtool will get stuck in a loop, continually jumping back to 0x528
after reaching 0x534."
Fix it by shortening the length of the parent function so that the
functions no longer overlap.

====================
pull-request: bpf 2018-07-01
The following pull-request contains BPF updates for your *net* tree.
The main changes are:
1) A bpf_fib_lookup() helper fix to change the API before freeze to
return an encoding of the FIB lookup result and return the nexthop
device index in the params struct (instead of device index as return
code that we had before), from David.
2) Various BPF JIT fixes to address syzkaller fallout, that is, do not
reject progs when set_memory_*() fails since it could still be RO.
Also arm32 JIT was not using bpf_jit_binary_lock_ro() API which was
an issue, and a memory leak in s390 JIT found during review, from
Daniel.
3) Multiple fixes for sockmap/hash to address most of the syzkaller
triggered bugs. Usage with IPv6 was crashing, a GPF in bpf_tcp_close(),
a missing sock_map_release() routine to hook up to callbacks, and a
fix for an omitted bucket lock in sock_close(), from John.
4) Two bpftool fixes to remove duplicated error message on program load,
and another one to close the libbpf object after program load. One
additional fix for nfp driver's BPF offload to avoid stopping offload
completely if replace of program failed, from Jakub.
5) Couple of BPF selftest fixes that bail out in some of the test
scripts if the user does not have the right privileges, from Jeffrin.
6) Fixes in test_bpf for s390 when CONFIG_BPF_JIT_ALWAYS_ON is set
where we need to set the flag that some of the test cases are expected
to fail, from Kleber.
7) Fix to detangle BPF_LIRC_MODE2 dependency from CONFIG_CGROUP_BPF
since it has no relation to it and lirc2 users often have configs
without cgroups enabled and thus would not be able to use it, from Sean.
8) Fix a selftest failure in sockmap by removing a useless setrlimit()
call that would set a too low limit where at the same time we are
already including bpf_rlimit.h that does the job, from Yonghong.
9) Fix BPF selftest config with missing missing NET_SCHED, from Anders.

libbpf used to be able to load programs from the default section
called '.text'. It's not very common to leave sections unnamed,
but if it happens libbpf will fail to load the programs reporting
-EINVAL from the kernel. The -EINVAL comes from bpf_obj_name_cpy()
because since 48cca7e44f9f ("libbpf: add support for bpf_call")
libbpf does not resolve program names for programs in '.text',
defaulting to '.text'. '.text', however, does not pass the
(isalnum(*src) || *src == '_') check in bpf_obj_name_cpy().
With few extra lines of code we can limit the pseudo call
assumptions only to objects which actually contain code relocations.

Commit 4bfe3bd3cc35 ("tools/bpftool: use version from the kernel

equal to the kernel version and obtained by running make kernelversion
against kernel source tree. Version is then communicated
to the sources with a command line define set in CFLAGS.
Use a simply expanded variable for the version, otherwise the
recursive make will run every time CFLAGS are used.
This brings the single-job compilation time for me from almost

Pull block fixes from Jens Axboe:
"Small set of fixes for this series. Mostly just minor fixes, the only
oddball in here is the sg change.
The sg change came out of the stall fix for NVMe, where we added a
mempool and limited us to a single page allocation. CONFIG_SG_DEBUG
sort-of ruins that, since we'd need to account for that. That's
actually a generic problem, since lots of drivers need to allocate SG
lists. So this just removes support for CONFIG_SG_DEBUG, which I added
back in 2007 and to my knowledge it was never useful.

Commit 546eb0317cfa "libnvdimm, pmem: Do not flush power-fail protected CPU caches"
fixed the write_cache detection to correctly show the lack of a write
cache based on the platform capabilities described in the ACPI NFIT. The
nfit_test unit tests expected a write cache to be present, so change the
nfit test namespaces to only advertise a persistence domain limited to
the memory controller. This allows the kernel to show a write_cache
attribute, and the test behaviour remains unchanged.

This test aims for both stand alone and internal usage by the resource
infra. The test receives the number routes to offload and checks:
- The routes were offloaded correctly
- Traffic for each route.

Add a selftest that can be used to perform basic sanity of the devlink
resource API as well as test the behavior of KVD manipulation in the
driver.
This is the first case of a HW-only test - in order to test the devlink
resource a driver capable of exposing resources has to be provided
first.

This library builds on top of devlink_lib.sh and contains functionality
specific to Spectrum ASICs, e.g., re-partitioning the various KVD
sub-parts.

setup_wait() and tc_offload_check() both assume that all NUM_NETIFS
interfaces are relevant for a given test. However, the scale test script
acts as an umbrella for a number of sub-tests, some of which may not
require all the interfaces.
Thus it's suboptimal for tc_offload_check() to query all the interfaces.
In case of setup_wait() it's incorrect, because the sub-test in question
of course doesn't configure any interfaces beyond what it needs, and
setup_wait() then ends up waiting indefinitely for the extraneous
interfaces to come up.
For that reason, give setup_wait() and tc_offload_check() an optional
parameter with a number of interfaces to probe. Fall back to global
NUM_NETIFS if the parameter is not given.

In the scale testing scenarios, one usually has a condition that is
expected to either fail, or pass, depending on which side of the scale
is being tested.
To capture this logic, add a function check_err_fail(), which dispatches
either to check_err() or check_fail(), depending on the value of the
first argument, should_fail.

The devlink related scripts are mlxsw-specific. As a result, they'll
reside in a different directory - but would still need the common logic
implemented in lib.sh.
So as a preliminary step, allow lib.sh to be sourced from other
directories as well.

Create unittests for the tc tunnel_key action.
v2:
For the tests expecting failures, added non-zero exit codes in the
teardowns. This prevents those tests from failing if the act_tunnel_key
module is unloaded.

When running the test on soft devices, there's no mechanism to
gratuitously start resolving the neighbor for remote tunnel endpoint.
So instead of passively waiting, wait for the device to be up, and then
probe the neighbor with a ping.

When running mirror_gre_bridge_1d_vlan tests on veth, several issues
cause spurious failures:
- vlan_ethtype should be ip, not ipv6 even in mirror-to-ip6gretap case,
because the overlay packet is still IPv4.
- Similarly ip_proto matches the innermost IP protocol, so can't be used
to filter out GRE packet. Drop the corresponding condition.
- Because the above fixes the filters to match in slow path as well,
they need to be made skip_hw so as not to double-count packets.

There are several cases where traffic that would normally be forwarded
in silicon needs to be observed in slow path. That's achieved by
trapping such traffic, and the functions trap_install() and
trap_uninstall() realize that. However, such treatment is obviously
wrong if the device in question is actually a soft device not backed by
an ASIC.
Therefore try to trap if possible, but fall back to inserting a continue
if not.

This was introduced more than a decade ago when sg chaining was
added, but we never really caught anything with it. The scatterlist
entry size can be critical, since drivers allocate it, so remove
the magic member. Recently it's been triggering allocation stalls
and failures in NVMe.
