Clang noticed that some none-zero sleep()s were actually using zero
anyway. This switches to nanosleep() to gain sub-second granularity.

The pid ns cannot be unshare()d as an unprivileged user without owning the
userns as well. Let's unshare the userns so that we can subsequently
unshare the pidns.
This also means that we don't need to set the no new privs bit as in the
other test cases, since we're unsharing the userns.

seccomp() doesn't allow users who aren't root in their userns to attach
filters unless they have the nnp bit set, so let's set it so that these
tests can pass when run as an unprivileged user.
This idea stolen from the other seccomp tests, which use this trick :)

The get_metadata() test requires real root, so let's skip it if we're not
real root.
Note that I used XFAIL here because that's what the test does later if
CONFIG_CHEKCKPOINT_RESTORE happens to not be enabled. After looking at the
code, there doesn't seem to be a nice way to skip tests defined as TEST(),
since there's no return code (I tried exit(KSFT_SKIP), but that didn't work
either...). So let's do it this way to be consistent, and easier to fix
when someone comes along and fixes it.

While playing around with a way to skip the seccomp get_metadata test, I
noticed that this header uses printf() without defining it, leading to,

This this test forks a child, and then the parent waits for a write() to a
pipe signalling the child is ready to be attached to. If something in the
child ASSERTs before it does this write, the test will hang waiting for it.
Instead, let's EXPECT, so that execution continues until we do the write.
Any failure after that is fine and can ASSERT.

With a suitably defined "probe:vfs_getname" probe, 'perf trace' can
"beautify" its output, so syscalls like open() or openat() can print the
"filename" argument instead of just its hex address, like:
$ perf trace -e open -- touch /dev/null
[...]
0.590 ( 0.014 ms): touch/18063 open(filename: /dev/null, flags: CREAT|NOCTTY|NONBLOCK|WRONLY, mode: IRUGO|IWUGO) = 3
[...]
The output without such beautifier looks like:
0.529 ( 0.011 ms): touch/18075 open(filename: 0xc78cf288, flags: CREAT|NOCTTY|NONBLOCK|WRONLY, mode: IRUGO|IWUGO) = 3
However, when the vfs_getname probe expands to multiple probes and it is
not the first one that is hit, the beautifier fails, as following:
0.326 ( 0.010 ms): touch/18072 open(filename: , flags: CREAT|NOCTTY|NONBLOCK|WRONLY, mode: IRUGO|IWUGO) = 3
Fix it by hooking into all the expanded probes (inlines), now, for instance:
[root@quaco ~]# perf probe -l
probe:vfs_getname (on getname_flags:73@fs/namei.c with pathname)
probe:vfs_getname_1 (on getname_flags:73@fs/namei.c with pathname)
[root@quaco ~]# perf trace -e open* sleep 1
0.010 ( 0.005 ms): sleep/5588 openat(dfd: CWD, filename: /etc/ld.so.cache, flags: RDONLY|CLOEXEC) = 3
0.029 ( 0.006 ms): sleep/5588 openat(dfd: CWD, filename: /lib64/libc.so.6, flags: RDONLY|CLOEXEC) = 3
0.194 ( 0.008 ms): sleep/5588 openat(dfd: CWD, filename: /usr/lib/locale/locale-archive, flags: RDONLY|CLOEXEC) = 3
[root@quaco ~]#
Works, further verified with:
[root@quaco ~]# perf test vfs
65: Use vfs_getname probe to get syscall args filenames : Ok
66: Add vfs_getname probe to get syscall args filenames : Ok
67: Check open filename arg using perf trace + vfs_getname: Ok

When perf is built with the annobin plugin (RHEL8 build) extra symbols
are added to its binary:
# nm perf | grep annobin | head -10
0000000000241100 t .annobin_annotate.c
0000000000326490 t .annobin_annotate.c
0000000000249255 t .annobin_annotate.c_end
00000000003283a8 t .annobin_annotate.c_end
00000000001bce18 t .annobin_annotate.c_end.hot

00000000001bc3e2 t .annobin_annotate.c_end.unlikely

00000000001bce18 t .annobin_annotate.c.hot
00000000001bce18 t .annobin_annotate.c.hot
...
Those symbols have no use for report or annotation and should be
skipped. Moreover they interfere with the DWARF unwind test on the PPC
arch, where they are mixed with checked symbols and then the test fails:
# perf test dwarf -v
59: Test dwarf unwind :
--- start ---
test child forked, pid 8515
unwind: .annobin_dwarf_unwind.c:ip = 0x10dba40dc (0x2740dc)
...
got: .annobin_dwarf_unwind.c 0x10dba40dc, expecting test__arch_unwind_sample
unwind: failed with 'no error'
The annobin symbols are defined as NOTYPE/LOCAL/HIDDEN:
# readelf -s ./perf | grep annobin | head -1
40: 00000000001bce4f 0 NOTYPE LOCAL HIDDEN 13 .annobin_init.c
They can still pass the check for the label symbol. Adding check for
HIDDEN and INTERNAL (as suggested by Nick below) visibility and filter
out such symbols.
> Just to be awkward, if you are going to ignore STV_HIDDEN
> symbols then you should probably also ignore STV_INTERNAL ones
> as well... Annobin does not generate them, but you never know,
> one day some other tool might create some.

PowerPC hardware does not have a builtin latency filter (--ldlat) for
the "mem-load" event and perf_mem_events by default includes
"/ldlat=30/" which is causing a failure on PowerPC. Refactor the code to
support "perf mem/c2c" on PowerPC.

Notice that the use of the bitwise OR operator '|' always leads to true
in this particular case, which seems a bit suspicious due to the context
in which this expression is being used.

First set of IIO fixes for the 5.0 cycle.

- A few different fixes around the TS-pin handling.

- Not enough space in the buffer used to build the scan to allow for
the timestamp.

2) fix two potential deadlocks in syscall bpf lookup and prog_register,
from Martin and Alexei.
3) fix BTF to allow typedef on func_proto, from Yonghong.

Previously, bpf_num_possible_cpus() had a bug when calculating a
number of possible CPUs in the case of sparse CPU allocations, as
it was considering only the first range or element of
/sys/devices/system/cpu/possible.
E.g. in the case of "0,2-3" (CPU 1 is not available), the function
returned 1 instead of 3.
This patch fixes the function by making it parse all CPU ranges and
elements.

This adds the promised selftest for binderfs. It will verify the following
things:
- binderfs mounting works
- binder device allocation works
- performing a binder ioctl() request through a binderfs device works
- binder device removal works
- binder-control removal fails
- binderfs unmounting works
The tests are performed both privileged and unprivileged. The latter
verifies that binderfs behaves correctly in user namespaces.

Prog arrays don't have 'owner_prog_type' and 'owner_jited'
fields in their fdinfo when they are created. Those fields
are set and reported when first program is checked for
compatibility by bpf_prog_array_compatible().
This means that bpftool cannot expect the fields to always
be there. Currently trying to show maps on a system with
an un-owned prog array leads to a crash:
$ bpftool map show
389: prog_array name tail_call_map flags 0x0
Error: key 'owner_prog_type' not found in fdinfo
Error: key 'owner_jited' not found in fdinfo
key 4B value 4B max_entries 4 memlock 4096B
Segmentation fault (core dumped)
We pass a NULL pointer to atoi().
Remove the assumption that fdinfo keys are always present.
Add missing validations and remove the p_err() calls which
may lead to broken JSON output as caller will not propagate
the failure.

Passing EPERM during syscall skipping was confusing since the test wasn't
actually exercising the errno evaluation -- it was just passing a literal
"1" (EPERM). Instead, expand the tests to check both direct value returns
(positive, 45000 in this case), and errno values (negative, -ESRCH in this
case) to check both fake success and fake failure during syscall skipping.

The cpu-hotplug test assumes that we can offline the maximum CPU as
described by /sys/devices/system/cpu/offline. However, in the case
where the number of CPUs exceeds like kernel configuration then
the offline count can be greater than the present count and we end
up trying to test the offlining of a CPU that is not available to
offline. Fix this by testing the maximum present CPU instead.
Also, the test currently offlines the CPU and does not online it,
so fix this by onlining the CPU after the test.

Error: can't get prog info (29): Bad address
The problem is in the prog_fd_by_tag function not cleaning
the struct bpf_prog_info before another request, so the
previous program length is still in there and kernel assumes
it needs to dump the program, which fails because there's no
user pointer set.
Moving the struct bpf_prog_info declaration into the loop,
so it gets cleaned before each query.
