[ Upstream commit 094ffbd1d8eaa27ed426feb8530cb1456348b018 ]
The throbber could race with creation of the anchor entry and cause the
IDR to have zero entries in it, which would cause the test to fail.

Several test runners register individual worker threads with the

[ Upstream commit 7011d72588d16a9e5f5d85acbc8b10019809599c ]
The "First Fault Register" (FFR) is an SVE register that mimics a
predicate register, but clears bits when a load or store fails to handle
an element of a vector. The supposed usage scenario is to initialise
this register (using SETFFR), then *read* it later on to learn about
elements that failed to load or store. Explicit writes to this register
using the WRFFR instruction are only supposed to *restore* values
previously read from the register (for context-switching only).
As the manual describes, this register holds only certain values, it:
"... contains a monotonic predicate value, in which starting from bit 0
there are zero or more 1 bits, followed only by 0 bits in any remaining
bit positions."
Any other value is UNPREDICTABLE and is not supposed to be "restored"
into the register.
The SVE test currently tries to write a signature pattern into the
register, which is *not* a canonical FFR value. Apparently the existing
setups treat UNPREDICTABLE as "read-as-written", but a new
implementation actually only stores canonical values. As a consequence,
the sve-test fails immediately when comparing the FFR value:
-----------
# ./sve-test
Vector length: 128 bits
PID: 207
Mismatch: PID=207, iteration=0, reg=48
Expected [cf00]
Got [0f00]
Aborted
-----------
Fix this by only populating the FFR with proper canonical values.
Effectively the requirement described above limits us to 17 unique
values over 16 bits worth of FFR, so we condense our signature down to 4
bits (2 bits from the PID, 2 bits from the generation) and generate the
canonical pattern from it. Any bits describing elements above the
minimum 128 bit are set to 0.
This aligns the FFR usage to the architecture and fixes the test on
microarchitectures implementing FFR in a more restricted way.

commit 0a13e3537ea67452d549a6a80da3776d6b7dedb3 upstream.
Fix up test_verifier error messages for the case where the original error
message changed, or for the case where pointer alu errors differ between
privileged and unprivileged tests. Also, add alternative tests for keeping
coverage of the original verifier rejection error message (fp alu), and
newly reject map_ptr += rX where rX == 0 given we now forbid alu on these
types for unprivileged. All test_verifier cases pass after the change. The
test case fixups were kept separate to ease backporting of core changes.

commit edcbf5137f093b5502f5f6b97cce3cbadbde27aa upstream.
When mirroring to a gretap in hardware the device expects to be
programmed with the egress port and all the encapsulating headers. This
requires the driver to resolve the path the packet will take in the
software data path and program the device accordingly.
If the path cannot be resolved (in this case because of an unresolved
neighbor), then mirror installation fails until the path is resolved.
This results in a race that causes the test to sometimes fail.
Fix this by setting the neighbor's state to permanent, so that it is
always valid.

commit 6185266c5a853bb0f2a459e3ff594546f277609b upstream.
The verifier test labelled "valid read map access into a read-only array
2" calls the bpf_csum_diff() helper and checks its return value. However,
architecture implementations of csum_partial() (which is what the helper
uses) differ in whether they fold the return value to 16 bit or not. For
example, x86 version has ...
if (unlikely(odd)) {
result = from32to16(result);
result = ((result >> 8) & 0xff) | ((result & 0xff) << 8);
}
... while generic lib/checksum.c does:
result = from32to16(result);
if (odd)
result = ((result >> 8) & 0xff) | ((result & 0xff) << 8);
This makes the helper return different values on different architectures,
breaking the test on non-x86. To fix this, add an additional instruction
to always mask the return value to 16 bits, and update the expected return
value accordingly.

commit 557c223b643a35effec9654958d8edc62fd2603a upstream.
In bpf geneve tunnel test we set geneve option on tx side. On rx side we
only call bpf_skb_get_tunnel_opt(). Since commit 9c2e14b48119 ("ip_tunnels:
Set tunnel option flag when tunnel metadata is present") geneve_rx() will
not add TUNNEL_GENEVE_OPT flag if there is no geneve option, which cause
bpf_skb_get_tunnel_opt() return ENOENT and _geneve_get_tunnel() in
test_tunnel_kern.c drop the packet.
As it should be valid that bpf_skb_get_tunnel_opt() return error when
there is not tunnel option, there is no need to drop the packet and
break all geneve rx traffic. Just set opt_class to 0 in this test and
keep returning TC_ACT_OK.

commit bfe3911a91047557eb0e620f95a370aee6a248c7 upstream.
Userspace has discovered the functionality offered by SYS_kcmp and has
started to depend upon it. In particular, Mesa uses SYS_kcmp for
os_same_file_description() in order to identify when two fd (e.g. device
or dmabuf) point to the same struct file. Since they depend on it for
core functionality, lift SYS_kcmp out of the non-default
CONFIG_CHECKPOINT_RESTORE into the selectable syscall category.
Rasmus Villemoes also pointed out that systemd uses SYS_kcmp to
deduplicate the per-service file descriptor store.
Note that some distributions such as Ubuntu are already enabling
CHECKPOINT_RESTORE in their configs and so, by extension, SYS_kcmp.

usr/include dir
[ Upstream commit 64ba3d591c9d2be2a9c09e99b00732afe002ad0d ]
Copied in from somewhere else, the makefile was including
the kerne's usr/include dir, which caused the asm/ioctl.h file
to be used.
Unfortunately, that file has different values for _IOC_SIZEBITS
and _IOC_WRITE than include/uapi/asm-generic/ioctl.h which then
causes the _IOCW macros to give the wrong ioctl numbers,
specifically for DMA_BUF_IOCTL_SYNC.
This patch simply removes the extra include from the Makefile

[ Upstream commit dd3a44c06f7b4f14e90065bf05d62c255b20005f ]
Newer binutils (>= 2.36) refuse to assemble lmw/stmw when building in
little endian mode. That breaks compilation of our alignment handler
test:
/tmp/cco4l14N.s: Assembler messages:

make[2]: *** [../../lib.mk:139: /output/kselftest/powerpc/alignment/alignment_handler] Error 1
These tests do pass on little endian machines, as the kernel will
still emulate those instructions even when running little

But we don't really need to test that case, so ifdef those

Use three-way comparison for address components to avoid integer
wraparound in the result of xfrm_policy_addr_delta(). This ensures
that the search trees are built and traversed correctly.
Treat IPv4 and IPv6 similarly by returning 0 when prefixlen == 0.
Prefix /0 has only one equivalence class.

$ echo $?
0
This is because the $lret in check_xfrm() is not a local variable.
Therefore when a test failed in check_exceptions(), the non-zero $lret
will later get reset to 0 when the next test calls check_xfrm().
With this fix, the final return value will be 1. Make it easier for
testers to spot this failure.

commit fb3558127cb62ba2dea9e3d0efa1bb1d7e5eee2a upstream.
Before this patch, profiler.inc.h wouldn't compile with clang-11 (before
the __builtin_preserve_enum_value LLVM builtin was introduced in
https://reviews.llvm.org/D83242).
Another test that uses this builtin (test_core_enumval) is conditionally
skipped if the compiler is too old. In that spirit, this patch inhibits
part of populate_cgroup_info(), which needs this CO-RE builtin. The
selftests build again on clang-11.
The affected test (the profiler test) doesn't pass on clang-11 because
it's missing https://reviews.llvm.org/D85570, but at least the test suite
as a whole compiles. The test's expected failure is already called out in
the README.

commit 1a3449c19407a28f7019a887cdf0d6ba2444751a upstream.
If Makefile cannot find any of the vmlinux's in its VMLINUX_BTF_PATHS list,
it tries to run btftool incorrectly, with VMLINUX_BTF unset:
bpftool btf dump file $(VMLINUX_BTF) format c
Such that the keyword 'format' is misinterpreted as the path to vmlinux.
The resulting build error message is fairly cryptic:
GEN vmlinux.h
Error: failed to load BTF from format: No such file or directory
This patch makes the failure reason clearer by yielding this instead:
Makefile:...: *** Cannot find a vmlinux for VMLINUX_BTF at any of
"{paths}". Stop.

[ Upstream commit 5316a7c0130acf09bfc8bb0092407006010fcccc ]
Adds new 2 new tests to the PTMU script: pmtu_ipv4/6_route_change.
These tests explicitly test for a recently discovered problem in the
IPv6 routing framework where PMTU exceptions were not properly released
when replacing a route via "ip route change ...".
After creating PMTU exceptions, the route from the device A to R1 will be
replaced with a new route, then device A will be deleted. If the PMTU
exceptions were properly cleaned up by the kernel, this device deletion
will succeed. Otherwise, the unregistration of the device will stall, and
messages such as the following will be logged in dmesg:
unregister_netdevice: waiting for veth_A-R1 to become free. Usage count = 4

The selftests/bpf Makefile includes system include directories from
the host, when building BPF programs. On RISC-V glibc requires that
__riscv_xlen is defined. This is not the case for "clang -target bpf",

the build.
By explicitly defining __risc_xlen correctly for riscv, we can
workaround this.
