commit 82ce6eb1dd13fd12e449b2ee2c2ec051e6f52c43 upstream.
A test for the basic NAT functionality uses ip command which needs veth
device. There is a condition where the kernel support for veth is not
compiled into the kernel and the test script breaks. This patch contains
code for reasonable error display and correct code exit.

commit fe48319243a626c860fd666ca032daacc2ba84a5 upstream.
When running under a pipe, some timer tests would not report output in
real-time because stdout flushes were missing after printf()s that lacked
a newline. This adds them to restore real-time status output that humans

commit fc82d93e57e3d41f79eff19031588b262fc3d0b6 upstream.

sense to set a 198.51.100.1 local address. Should be a typo.

commit 0979ff7992fb6f4eb837995b12f4071dcafebd2d upstream.
Currently, ksym_search located at trace_helpers won't check symbols are
existing or not.
In ksym_search, when symbol is not found, it will return &syms[0](_stext).
But when the kernel symbols are not loaded, it will return NULL, which is
not a desired action.
This commit will add verification logic whether symbols are loaded prior
to the symbol search.

commit 6cea33701eb024bc6c920ab83940ee22afd29139 upstream.
Test test_libbpf.sh failed on my development server with failure
-bash-4.4$ sudo ./test_libbpf.sh
[0] libbpf: Error in bpf_object__probe_name():Operation not permitted(1).
Couldn't load basic 'r0 = 0' BPF program.
test_libbpf: failed at file test_l4lb.o
selftests: test_libbpf [FAILED]
-bash-4.4$
The reason is because my machine has 64KB locked memory by default which
is not enough for this program to get locked memory.
Similar to other bpf selftests, let us increase RLIMIT_MEMLOCK
to infinity, which fixed the issue.

commit becf2319f320cae43e20cf179cc51a355a0deb5f upstream.
When an icmp error such as pkttoobig is received, conntrack checks
if the "inner" header (header of packet that did not fit link mtu)
is matches an existing connection, and, if so, sets that packet as
being related to the conntrack entry it found.
It was recently reported that this "related" setting also works
if the inner header is from another, different connection (i.e.,
artificial/forged icmp error).
Add a test, followup patch will add additional "inner dst matches
outer dst in reverse direction" check before setting related state.

commit a5f622984a623df9a84cf43f6b098d8dd76fbe05 upstream.
A couple of tests are verifying a route has been removed. The helper
expects the prefix as the first part of the expected output. When
checking that a route has been deleted the prefix is empty leading
to an invalid ip command:
$ ip ro ls match
Command line is not complete. Try option "help"
Fix by moving the comparison of expected output and output to a new
function that is used by both check_route and check_route6. Use the
new helper for the 2 checks on route removal.
Also, remove the reset of 'set -x' in route_setup which overrides the
user managed setting.

commit 3aa415dd2128e478ea3225b59308766de0e94d6b upstream.
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.

commit af548a27b158d548d41e56255e6eaca1658cc3be upstream.
Just like commit e2ba732a1681 ("selftests: fib_tests: sleep after
changing carrier"), wait one second to allow linkwatch to propagate the
carrier change to the stack.
There are two sets of carrier tests. The first slept after the carrier
was set to off, and when the second set ran, it was likely that the
linkwatch would be able to run again without much delay, reducing the
likelihood of a race. However, if you run 'fib_tests.sh -t carrier' on a
loop, you will quickly notice the failures.
Sleeping on the second set of tests make the failures go away.

commit 7c0cdf0b3940f63d9777c3fcf250a2f83859ca54 upstream.
trie_delete_elem() was deleting an entry even though it was not matching
if the prefixlen was correct. This patch adds a check on matchlen.
Reproducer:
$ sudo bpftool map create /sys/fs/bpf/mylpm type lpm_trie key 8 value 1 entries 128 name mylpm flags 1
$ sudo bpftool map update pinned /sys/fs/bpf/mylpm key hex 10 00 00 00 aa bb cc dd value hex 01
$ sudo bpftool map dump pinned /sys/fs/bpf/mylpm
key: 10 00 00 00 aa bb cc dd value: 01

$ sudo bpftool map delete pinned /sys/fs/bpf/mylpm key hex 10 00 00 00 ff ff ff ff
$ echo $?
0
$ sudo bpftool map dump pinned /sys/fs/bpf/mylpm
Found 0 elements
A similar reproducer is added in the selftests.
Without the patch:
$ sudo ./tools/testing/selftests/bpf/test_lpm_map
test_lpm_map: test_lpm_map.c:485: test_lpm_delete: Assertion `bpf_map_delete_elem(map_fd, key) == -1 && errno == ENOENT' failed.

commit 1bb54c4071f585ebef56ce8fdfe6026fa2cbcddd upstream.
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.

commit 2b531b6137834a55857a337ac17510d6436b6fbb upstream.
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.

It's GNU Make and linker specific.
The default Makefile rule looks like:
$(CC) $(CFLAGS) $(LDFLAGS) $@ $^ $(LDLIBS)
When linking is done by gcc itself, no issue, but when it needs to be passed
to proper ld, only LDLIBS follows and then ld cannot know what libs to link
with.
More detail:
https://www.gnu.org/software/make/manual/html_node/Implicit-Variables.html
LDFLAGS
Extra flags to give to compilers when they are supposed to invoke the linker,
‘ld’, such as -L. Libraries (-lfoo) should be added to the LDLIBS variable
instead.
LDLIBS
Library flags or names given to compilers when they are supposed to invoke the
linker, ‘ld’. LOADLIBES is a deprecated (but still supported) alternative to
LDLIBS. Non-library linker flags, such as -L, should go in the LDFLAGS
variable.
https://lkml.org/lkml/2010/2/10/362
tools/perf: libraries must come after objects
Link order matters, use LDLIBS instead of LDFLAGS to properly link against
libpthread.

commit f67ad87ab3120e82845521b18a2b99273a340308 upstream.
While running test_progs in a loop I found out that I'm sometimes hitting
"Didn't find expected build ID from the map" error.
Looking at stack_map_get_build_id_offset() it seems that it is racy (by
design) and can sometimes return BPF_STACK_BUILD_ID_IP (i.e. can't trylock
current->mm->mmap_sem).
Let's retry this test a single time.

commit 91fa038d9446b5bf5ea80822790af7dd9bcbb5a2 upstream.
In iproute2 commit 90c5c969f0b9 ("fix print_0xhex on 32 bit"), the format
specifier for the ife type changed from 0x%X to %#llX, causing systematic
failures in the following TDC test cases:

Change 'matchPattern' values, allowing '0' and '0x0' if ife type is equal
to 0, and accepting both '0x' and '0X' otherwise, to let these tests pass
both with old and new tc binaries.
While at it, fix a small typo in test case fac3 ('maximnum'->'maximum').

commit 976b4f3a4646fbf0d189caca25f91f82e4be4b5a upstream.
Test that sys_sendmsg BPF hook doesn't break sys_sendmsg behaviour to
rewrite destination IPv6 = [::] with [::1] (BSD'ism).
Two test cases are added:
1) User passes dst IPv6 = [::] and BPF_CGROUP_UDP6_SENDMSG program
doesn't touch it.
2) User passes dst IPv6 != [::], but BPF_CGROUP_UDP6_SENDMSG program
rewrites it with [::].
In both cases [::1] is used by sys_sendmsg code eventually and datagram
is sent successfully for unconnected UDP socket.
Example of relevant output:
Test case: sendmsg6: set dst IP = [::] (BSD'ism) .. [PASS]
Test case: sendmsg6: preserve dst IP = [::] (BSD'ism) .. [PASS]

commit a0517a0f7ef23550b4484c37e2b9c2d32abebf64 upstream.
For some reason, my older GCC (< 4.8) isn't smart enough to optimize the
!__builtin_constant_p() branch in bpf_htons, I see:
error: implicit declaration of function '__builtin_bswap16'
Let's use __bpf_constant_htons as suggested by Daniel Borkmann.
I tried to use simple htons, but it produces the following:
test_progs.c:54:17: error: braced-group within expression allowed only
inside a function
.eth.h_proto = htons(ETH_P_IP),

commit ed5f13261cb65b02c611ae9971677f33581d4286 upstream.
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.

commit 4f7b3e82589e0de723780198ec7983e427144c0a upstream.
pathological bpf programs may try to force verifier to explode in
the number of branch states:
20: (d5) if r1 s<= 0x24000028 goto pc+0
21: (b5) if r0 <= 0xe1fa20 goto pc+2
22: (d5) if r1 s<= 0x7e goto pc+0
23: (b5) if r0 <= 0xe880e000 goto pc+0
24: (c5) if r0 s< 0x2100ecf4 goto pc+0
25: (d5) if r1 s<= 0xe880e000 goto pc+1
26: (c5) if r0 s< 0xf4041810 goto pc+0
27: (d5) if r1 s<= 0x1e007e goto pc+0
28: (b5) if r0 <= 0xe86be000 goto pc+0
29: (07) r0 += 16614
30: (c5) if r0 s< 0x6d0020da goto pc+0
31: (35) if r0 >= 0x2100ecf4 goto pc+0
Teach verifier to recognize always taken and always not taken branches.
This analysis is already done for == and != comparison.
Expand it to all other branches.
It also helps real bpf programs to be verified faster:
