The test should be skipped if initial conditions aren't fulfilled in the
start instead of failing and outputting non-compliant TAP logs. This kind
of failure pollutes the results. The initial conditions are:
- The test should only execute if /tmp file can be allocated.
- The test should only execute if huge pages are free.
Before:
TAP version 13

Close a socket with dump in progress. We need a dump which generates
enough info not to fit into a single skb. Policy dump fits the bill.
Use the trick discovered by syzbot for keeping a ref on the socket
longer than just close, with mqueue.

1..3

# RUN global.test_sanity ...
# OK global.test_sanity

# PASSED: 3 / 3 tests passed.
# Totals: pass:3 fail:0 xfail:0 xpass:0 skip:0 error:0
Note that this test is not expected to fail but rather crash
the kernel if we get the cleanup wrong.

Add push/pop checking for msg_verify_data in test_sockmap, except for
pop/push with cork tests, in these tests the logic will be different.
1. With corking, pop/push might not be invoked in each sendmsg, it makes
the layout of the received data difficult
2. It makes it hard to calculate the total_bytes in the recvmsg
Temporarily skip the data integrity test for these cases now, added a TODO

total_bytes in msg_loop_rx should also take push into account, otherwise
total_bytes will be a smaller value, which makes the msg_loop_rx end early.
Besides, total_bytes has already taken pop into account, so we don't need
to subtract some bytes from iov_buf in sendmsg_test. The additional
subtraction may make total_bytes a negative number, and msg_loop_rx will
just end without checking anything.

In the SENDPAGE test, "opt->iov_length * cnt" size of data will be sent
cnt times by sendfile.
1. In push/pop tests, they will be invoked cnt times, for the simplicity of

2. Change iov_length in test_send_large from 1024 to 8192. We have pop test

Recently, the net/lib.sh file has been modified to include defer.sh from
net/lib/sh/ directory. The Makefile from net/lib has been modified
accordingly, but not the ones from the sub-targets using net/lib.sh.
Because of that, the new file is not installed as expected when
installing the Forwarding, MPTCP, and Netfilter targets, e.g.
# make -C tools/testing/selftests TARGETS=net/mptcp install \
INSTALL_PATH=/tmp/kself
# cd /tmp/kself/
# ./run_kselftest.sh -c net/mptcp
TAP version 13

# timeout set to 1800
# selftests: net/mptcp: mptcp_connect.sh
# ./../lib.sh: line 5: /tmp/kself/net/lib/sh/defer.sh: No such file
or directory
# (...)
This can be fixed simply by adding all the .sh files from net/lib/sh
directory to the TEST_INCLUDES variable in the different Makefile's.

As reported by Byeonguk, the bad_words test in verifier_bits_iter.c
occasionally fails on s390 host. Quoting Ilya's explanation:
s390 kernel runs in a completely separate address space, there is no
user/kernel split at TASK_SIZE. The same address may be valid in both
the kernel and the user address spaces, there is no way to tell by
looking at it. The config option related to this property is
ARCH_HAS_NON_OVERLAPPING_ADDRESS_SPACE.
Also, unfortunately, 0 is a valid address in the s390 kernel address
space.
Fix the issue by using -4095 as the bad address for bits iterator, as
suggested by Ilya. Verify that bpf_iter_bits_new() returns -EINVAL for
NULL address and -EFAULT for bad address.

Disable strict aliasing, as has been done in the kernel proper for decades
(literally since before git history) to fix issues where gcc will optimize
away loads in code that looks 100% correct, but is _technically_ undefined
behavior, and thus can be thrown away by the compiler.
E.g. arm64's vPMU counter access test casts a uint64_t (unsigned long)
pointer to a u64 (unsigned long long) pointer when setting PMCR.N via
u64p_replace_bits(), which gcc-13 detects and optimizes away, i.e. ignores
the result and uses the original PMCR.
The issue is most easily observed by making set_pmcr_n() noinline and
wrapping the call with printf(), e.g. sans comments, for this code:
printf("orig = %lx, next = %lx, want = %lu\n", pmcr_orig, pmcr, pmcr_n);
set_pmcr_n(&pmcr, pmcr_n);
printf("orig = %lx, next = %lx, want = %lu\n", pmcr_orig, pmcr, pmcr_n);
gcc-13 generates:
0000000000401c90 <set_pmcr_n>:
401c90: f9400002 ldr x2, [x0]
401c94: b3751022 bfi x2, x1, #11, #5

with the value stored in [sp + 0x60] ignored by both printf() above and
in the test proper, resulting in a false failure due to vcpu_set_reg()
simply storing the original value, not the intended value.

Somewhat bizarrely, gcc-11 also exhibits the same behavior, but only if

is inlined in its sole caller.

Extend netcons_basic selftest to verify the userdata functionality by:
1. Creating a test key in the userdata configfs directory
2. Writing a known value to the key
3. Validating the key-value pair appears in the captured network output

Pull cxl fixes from Ira Weiny:
"The bulk of these fixes center around an initialization order bug
reported by Gregory Price and some additional fall out from the
debugging effort.
In summary, cxl_acpi and cxl_mem race and previously worked because of
a bus_rescan_devices() while testing without modules built in.
Unfortunately with modules built in the rescan would fail due to the
cxl_port driver being registered late via the build order. Furthermore
it was found bus_rescan_devices() did not guarantee a probe barrier
which CXL was expecting. Additional fixes to cxl-test and decoder
allocation came along as they were found in this debugging effort.
The other fixes are pretty minor but one affects trace point data seen
by user space.
Summary:
- Fix crashes when running with cxl-test code
- Fix Trace DRAM Event Record field decodes
- Fix module/built in initialization order errors
- Fix use after free on decoder shutdowns
- Fix out of order decoder allocations
- Improve cxl-test to better reflect real world systems"

The HSR test, hsr_ping.sh, actually needs 7 min to run. Around 375s to
be exact, and even more on a debug kernel or kernel with other network
security limits. The timeout setting for the kselftest is currently 45
seconds, which is way too short to integrate hsr tests to run_kselftest
infrastructure. However, timeout of hundreds of seconds is quite a long
time, especially in a CI/CD environment. It seems that we need
accelerate the test and balance with timeout setting.
The most time-consuming func is do_ping_long, where ping command sends
10 packages to the given address. The default interval between two ping
packages is 1s according to the ping Mannual. There isn't any operation
between pings thus we could pass -i 0.1 to ping to make it 10 times
faster.
While even with this short interval, the test still need about 46.4
seconds to finish because of the two HSR interfaces, each of which is
tested by calling do_ping func 12 times and do_ping_long func 19 times
and sleep for 3s.
So, an explicit setting is also needed to slightly increase the
timeout. And to leave us some slack, use 50 as default timeout.

Add more test cases for bits iterator:
(1) huge word test
Verify the multiplication overflow of nr_bits in bits_iter. Without
the overflow check, when nr_words is 67108865, nr_bits becomes 64,
causing bpf_probe_read_kernel_common() to corrupt the stack.
(2) max word test
Verify correct handling of maximum nr_words value (511).
(3) bad word test
Verify early termination of bits iteration when bits iterator
initialization fails.

Hou Tao reported an issue with bpf_fastcall patterns allowing extra
stack space above MAX_BPF_STACK limit. This extra stack allowance is
not integrated properly with the following verifier parts:
- backtracking logic still assumes that stack can't exceed
MAX_BPF_STACK;
- bpf_verifier_env->scratched_stack_slots assumes only 64 slots are
available.
Here is an example of an issue with precision tracking
(note stack slot -8 tracked as precise instead of -520):
0: (b7) r1 = 42 ; R1_w=42
1: (b7) r2 = 42 ; R2_w=42
2: (7b) *(u64 *)(r10 -512) = r1 ; R1_w=42 R10=fp0 fp-512_w=42
3: (7b) *(u64 *)(r10 -520) = r2 ; R2_w=42 R10=fp0 fp-520_w=42
4: (85) call bpf_get_smp_processor_id#8 ; R0_w=scalar(...)
5: (79) r2 = *(u64 *)(r10 -520) ; R2_w=42 R10=fp0 fp-520_w=42
6: (79) r1 = *(u64 *)(r10 -512) ; R1_w=42 R10=fp0 fp-512_w=42
7: (bf) r3 = r10 ; R3_w=fp0 R10=fp0
8: (0f) r3 += r2
mark_precise: frame0: last_idx 8 first_idx 0 subseq_idx -1
mark_precise: frame0: regs=r2 stack= before 7: (bf) r3 = r10
mark_precise: frame0: regs=r2 stack= before 6: (79) r1 = *(u64 *)(r10 -512)
mark_precise: frame0: regs=r2 stack= before 5: (79) r2 = *(u64 *)(r10 -520)
mark_precise: frame0: regs= stack=-8 before 4: (85) call bpf_get_smp_processor_id#8
mark_precise: frame0: regs= stack=-8 before 3: (7b) *(u64 *)(r10 -520) = r2
mark_precise: frame0: regs=r2 stack= before 2: (7b) *(u64 *)(r10 -512) = r1
mark_precise: frame0: regs=r2 stack= before 1: (b7) r2 = 42
9: R2_w=42 R3_w=fp42
9: (95) exit
This patch disables the additional allowance for the moment.
Also, two test cases are removed:
- bpf_fastcall_max_stack_ok:
it fails w/o additional stack allowance;
- bpf_fastcall_max_stack_fail:
this test is no longer necessary, stack size follows
regular rules, pattern invalidation is checked by other
test cases.
