[ Upstream commit 8a89015644 ]
As a side-effect of nftables' commit dbff26bfba833 ("cache: consolidate
reset command"), audit logs changed when more objects were reset than
fit into a single netlink message.
Since the objects' distribution in netlink messages is not relevant,
implement a summarizing function which combines repeated audit logs into
a single one with summed up 'entries=' value.

commit d0a29cdb6e upstream.
Suppose log="foo bar buz" and msg->substr="bar".
In such case current match processing logic would update 'log' as
follows: log += strlen(msg->substr); -> log += 3 -> log=" bar".
However, the intent behind the 'log' update is to make it point after
the successful match, e.g. to make log=" buz" in the example above.

[ Upstream commit f00bb757ed ]
__msg, __regex and __xlated tags are based on
__attribute__((btf_decl_tag("..."))) annotations.
Clang de-duplicates such annotations, e.g. the following
two sequences of tags are identical in final BTF:
/* seq A */ /* seq B */
__tag("foo") __tag("foo")
__tag("bar") __tag("bar")
__tag("foo")
Fix this by adding a unique suffix for each tag using __COUNTER__
pre-processor macro. E.g. here is a new definition for __msg:
#define __msg(msg) \
__attribute__((btf_decl_tag("comment:test_expect_msg=" XSTR(__COUNTER__) "=" msg)))
Using this definition the "seq A" from example above is translated to
BTF as follows:
[..] DECL_TAG 'comment:test_expect_msg=0=foo' type_id=X component_idx=-1
[..] DECL_TAG 'comment:test_expect_msg=1=bar' type_id=X component_idx=-1
[..] DECL_TAG 'comment:test_expect_msg=2=foo' type_id=X component_idx=-1
Surprisingly, this bug affects a single existing test:
verifier_spill_fill/old_stack_misc_vs_cur_ctx_ptr,
where sequence of identical messages was expected in the log.

[ Upstream commit 9c9f733913 ]
Add a macro __xlated("...") for use with test_loader tests.
When such annotations are present for the test case:
- bpf_prog_get_info_by_fd() is used to get BPF program after all
rewrites are applied by verifier.
- the program is disassembled and patterns specified in __xlated are
searched for in the disassembly text.
__xlated matching follows the same mechanics as __msg:
each subsequent pattern is matched from the point where
previous pattern ended.
This allows to write tests like below, where the goal is to verify the
behavior of one of the of the transformations applied by verifier:
SEC("raw_tp")
__xlated("1: w0 = ")
__xlated("2: r0 = &(void __percpu *)(r0)")
__xlated("3: r0 = *(u32 *)(r0 +0)")

[ Upstream commit 4ef5d6af49 ]
The call stack for validate_case() function looks as follows:
- test_loader__run_subtests()
- process_subtest()
- run_subtest()
- prepare_case(), which does 'tester->next_match_pos = 0';
- validate_case(), which increments tester->next_match_pos.
Hence, each subtest is run with next_match_pos freshly set to zero.
Meaning that there is no need to persist this variable in the
struct test_loader, use local variable instead.

[ Upstream commit 21c5f4f55d ]
Linux 5.1 implemented 64-bit time types and related syscalls to address the
Y2038 problem generally across archs. Userspace handling of Y2038 varies
with the libc however. While musl libc uses 64-bit time across all 32-bit
and 64-bit platforms, GNU glibc uses 64-bit time on 64-bit platforms but
defaults to 32-bit time on 32-bit platforms unless they "opt-in" to 64-bit
time or explicitly use 64-bit syscalls and time structures.
One specific area is the standard setsockopt() call, SO_TIMESTAMPNS option
used for timestamping, and the related output 'struct timespec'. GNU glibc
defaults as above, also exposing the SO_TIMESTAMPNS_NEW flag to explicitly
use a 64-bit call and 'struct __kernel_timespec'. Since these are not
exposed or needed with musl libc, their use in tc_redirect.c leads to
compile errors building for mips64el/musl:
tc_redirect.c: In function 'rcv_tstamp':
tc_redirect.c:425:32: error: 'SO_TIMESTAMPNS_NEW' undeclared (first use in this function); did you mean 'SO_TIMESTAMPNS'?
425 | cmsg->cmsg_type == SO_TIMESTAMPNS_NEW)
| ^~~~~~~~~~~~~~~~~~
| SO_TIMESTAMPNS
tc_redirect.c:425:32: note: each undeclared identifier is reported only once for each function it appears in
tc_redirect.c: In function 'test_inet_dtime':
tc_redirect.c:491:49: error: 'SO_TIMESTAMPNS_NEW' undeclared (first use in this function); did you mean 'SO_TIMESTAMPNS'?
491 | err = setsockopt(listen_fd, SOL_SOCKET, SO_TIMESTAMPNS_NEW,
| ^~~~~~~~~~~~~~~~~~
| SO_TIMESTAMPNS
However, using SO_TIMESTAMPNS_NEW isn't strictly needed, nor is Y2038 being
explicitly tested. The timestamp checks in tc_redirect.c are simple: the
packet receive timestamp is non-zero and processed/handled in less than 5
seconds.
Switch to using the standard setsockopt() call and SO_TIMESTAMPNS option to
ensure compatibility across glibc and musl libc. In the worst-case, there
is a 5-second window 14 years from now where tc_redirect tests may fail on
32-bit systems. However, we should reasonably expect glibc to adopt a
64-bit mandate rather than the current "opt-in" policy before the Y2038
roll-over.

[ Upstream commit aa95073fd2 ]
While building, bpftool makes a skeleton from test_core_extern.c, which
itself includes <stdbool.h> and uses the 'bool' type. However, the skeleton
test_core_extern.skel.h generated *does not* include <stdbool.h> or use the
'bool' type, instead using the C-only '_Bool' type. Compiling test_cpp.cpp
with g++ 12.3 for mips64el/musl-libc then fails with error:
In file included from test_cpp.cpp:9:
test_core_extern.skel.h:45:17: error: '_Bool' does not name a type
45 | _Bool CONFIG_BOOL;
| ^~~~~
This was likely missed previously because glibc uses a GNU extension for
<stdbool.h> with C++ (#define _Bool bool), not supported by musl libc.
Normally, a C fragment would include <stdbool.h> and use the 'bool' type,
and thus cleanly work after import by C++. The ideal fix would be for
'bpftool gen skeleton' to output the correct type/include supporting C++,
but in the meantime add a conditional define as above.

[ Upstream commit 03bfcda1fb ]
Current code parses arguments with strtok_r() using a construct like
char *state = NULL;
while ((next = strtok_r(state ? NULL : input, ",", &state))) {
...
}
where logic assumes the 'state' var can distinguish between first and
subsequent strtok_r() calls, and adjusts parameters accordingly. However,
'state' is strictly internal context for strtok_r() and no such assumptions
are supported in the man page. Moreover, the exact behaviour of 'state'
depends on the libc implementation, making the above code fragile.
Indeed, invoking "./test_progs -t <test_name>" on mips64el/musl will hang,
with the above code in an infinite loop.
Similarly, we see strange behaviour running 'veristat' on mips64el/musl:
$ ./veristat -e file,prog,verdict,insns -C two-ok add-failure
Can't specify more than 9 stats
Rewrite code using a counter to distinguish between strtok_r() calls.

[ Upstream commit 69f409469c ]
The addition of general support for unprivileged tests in test_loader.c
breaks building test_verifier on non-glibc (e.g. musl) systems, due to the
inclusion of glibc extension '<error.h>' in 'unpriv_helpers.c'. However,
the header is actually not needed, so remove it to restore building.

and causes problems, so drop them.

When resctrl is built on architectures without __cpuid_count()
support, build fails. resctrl uses __cpuid_count() defined in
kselftest.h.
Even though the problem is seen while building resctrl on aarch64,
this error can be seen on any platform that doesn't support CPUID.
CPUID is a x86/x86-64 feature and code paths with CPUID asm commands
will fail to build on all other architectures.
All others tests call __cpuid_count() do so from x86/x86_64 code paths
when _i386__ or __x86_64__ are defined. resctrl is an exception.
Fix the problem by defining __cpuid_count() only when __i386__ or
__x86_64__ are defined in kselftest.h and changing resctrl to call
__cpuid_count() only when __i386__ or __x86_64__ are defined.

Currently a number of SVE/SME related tests have almost identical
functions to enumerate all supported vector lengths. However over time
the copy&pasted code has diverged, allowing some bugs to creep in:
- fake_sigreturn_sme_change_vl reports a failure, not a SKIP if only
one vector length is supported (but the SVE version is fine)
- fake_sigreturn_sme_change_vl tries to set the SVE vector length, not
the SME one (but the other SME tests are fine)
- za_no_regs keeps iterating forever if only one vector length is
supported (but za_regs is correct)
Since those bugs seem to be mostly copy&paste ones, let's consolidate
the enumeration loop into one shared function, and just call that from
each test. That should fix the above bugs, and prevent similar issues
from happening again.

There is a recently notified BT regression with no fix yet. I do not
think a fix will land in the next week.
Current release - regressions:
- core: tighten bad gso csum offset check in virtio_net_hdr
- netfilter: move nf flowtable bpf initialization in
nf_flow_table_module_init()
- eth: ice: stop calling pci_disable_device() as we use pcim
- eth: fou: fix null-ptr-deref in GRO.
Current release - new code bugs:
- hsr: prevent NULL pointer dereference in hsr_proxy_announce()
Previous releases - regressions:
- hsr: remove seqnr_lock
- netfilter: nft_socket: fix sk refcount leaks
- mptcp: pm: fix uaf in __timer_delete_sync
- phy: dp83822: fix NULL pointer dereference on DP83825 devices
- eth: revert "virtio_net: rx enable premapped mode by default"
- eth: octeontx2-af: Modify SMQ flush sequence to drop packets
Previous releases - always broken:
- eth: mlx5: fix bridge mode operations when there are no VFs
- eth: igb: Always call igb_xdp_ring_update_tail() under Tx lock"

Similar to the previous commit, the net_helper.sh file from the parent
directory is used by the MPTCP selftests and it needs to be present when
running the tests.
This file then needs to be listed in the Makefile to be included when
exporting or installing the tests, e.g. with:
make -C tools/testing/selftests \
TARGETS=net/mptcp \
install INSTALL_PATH=$KSFT_INSTALL_PATH
cd $KSFT_INSTALL_PATH
./run_kselftest.sh -c net/mptcp

A new endpoint using the IP of the initial subflow has been recently
added to increase the code coverage. But it breaks the test when using
old kernels not having commit 86e39e0448 ("mptcp: keep track of local
endpoint still available for each msk"), e.g. on v5.15.
Similar to commit d4c81bbb86 ("selftests: mptcp: join: support local
endpoint being tracked or not"), it is possible to add the new endpoint
conditionally, by checking if "mptcp_pm_subflow_check_next" is present
in kallsyms: this is not directly linked to the commit introducing this
symbol but for the parent one which is linked anyway. So we can know in
advance what will be the expected behaviour, and add the new endpoint
only when it makes sense to do so.

Padding is not included in UDP and TCP checksums. Therefore, reduce the
length of the checksummed data to include only the data in the IP
payload. This fixes spurious reported checksum failures like
rx: pkt: sport=33000 len=26 csum=0xc850 verify=0xf9fe
pkt: bad csum
Technically it is possible for there to be trailing bytes after the UDP
data but before the Ethernet padding (e.g. if sizeof(ip) + sizeof(udp) +
udp.len < ip.len). However, we don't generate such packets.
