[ Upstream commit 6c20822fada1b8adb77fa450d03a0d449686a4a9 ]
&xdp_buff and &xdp_frame are bound in a way that
xdp_buff->data_hard_start == xdp_frame
It's always the case and e.g. xdp_convert_buff_to_frame() relies on
this.
IOW, the following:
for (u32 i = 0; i < 0xdead; i++) {
xdpf = xdp_convert_buff_to_frame(&xdp);
xdp_convert_frame_to_buff(xdpf, &xdp);
}
shouldn't ever modify @xdpf's contents or the pointer itself.
However, "live packet" code wrongly treats &xdp_frame as part of its
context placed *before* the data_hard_start. With such flow,
data_hard_start is sizeof(*xdpf) off to the right and no longer points
to the XDP frame.
Instead of replacing `sizeof(ctx)` with `offsetof(ctx, xdpf)` in several
places and praying that there are no more miscalcs left somewhere in the
code, unionize ::frm with ::data in a flex array, so that both starts
pointing to the actual data_hard_start and the XDP frame actually starts
being a part of it, i.e. a part of the headroom, not the context.
A nice side effect is that the maximum frame size for this mode gets
increased by 40 bytes, as xdp_buff::frame_sz includes everything from
data_hard_start (-> includes xdpf already) to the end of XDP/skb shared
info.
Also update %MAX_PKT_SIZE accordingly in the selftests code. Leave it
hardcoded for 64 bit && 4k pages, it can be made more flexible later on.
Minor: align `&head->data` with how `head->frm` is assigned for
consistency.
Minor #2: rename 'frm' to 'frame' in &xdp_page_head while at it for
clarity.
(was found while testing XDP traffic generator on ice, which calls
xdp_convert_frame_to_buff() for each XDP frame)

[ Upstream commit 2067e7a00aa604b94de31d64f29b8893b1696f26 ]
The test_local_dnat_portonly() function initiates the client-side as
soon as it sets the listening side to the background. This could lead to
a race condition where the server may not be ready to listen. To ensure
that the server-side is up and running before initiating the
client-side, a delay is introduced to the test_local_dnat_portonly()
function.
Before the fix:
# ./nft_nat.sh

PASS: ping to ns1-rthlYrBU was ip NATted to ns2-rthlYrBU

commit 8c710f75256bb3cf05ac7b1672c82b92c43f3d28 upstream.
The tcindex classifier has served us well for about a quarter of a century
but has not been getting much TLC due to lack of known users. Most recently
it has become easy prey to syzkaller. For this reason, we are retiring it.

commit 8677e555f17f51321d0730b945aeb7d4b95f998f upstream.
Update ptrace tests according to all potential Yama security policies.
This is required to make such tests pass even if Yama is enabled.
Tests are not skipped but they now check both Landlock and Yama boundary
restrictions at run time to keep a maximum test coverage (i.e. positive
and negative testing).

overlayfs may be disabled in the kernel configuration, causing related

Rather than trying to guess which implementation of "echo" to run with
support for "-ne" options, use "printf" instead of "echo -ne". It
handles escape characters as a standard feature and it is widespread
among modern shells.

[ Upstream commit 4ebe33398c40c1118b4d8546978036c0e0032d1b ]
Find the actual echo binary using $(which echo) and use it for
formatted output with -ne. On some systems, the default echo command
doesn't handle the -e option and the output looks like this (arm64
build):
-ne Emit Tests for alsa
-ne Emit Tests for amd-pstate
-ne Emit Tests for arm64
This is for example the case with the KernelCI Docker images
e.g. kernelci/gcc-10:x86-kselftest-kernelci. With the actual echo
binary (e.g. in /bin/echo), the output is formatted as expected (x86
build this time):
Emit Tests for alsa
Emit Tests for amd-pstate
Skipping non-existent dir: arm64
Only the install target is using "echo -ne" so keep the $ECHO variable
local to it.

[ Upstream commit f922c7b1c1c45740d329bf248936fdb78c0cff6e ]
When devlink instance is put into network namespace and that network
namespace gets deleted, devlink instance is moved back into init_ns.
This is done as a part of cleanup_net() routine. Since cleanup_net()
is called asynchronously from workqueue, there is no guarantee that
the devlink instance move is done after "ip netns del" returns.
So fix this race by making sure that the devlink instance is present
before any other operation.

[ Upstream commit b60417a9f2b890a8094477b2204d4f73c535725e ]
Usage of `set -e` before executing a command causes immediate exit
on failure, without cleanup up the resources allocated at setup.
This can affect the next tests that use the same resources,
leading to a chain of failures.
A simple fix is to always call cleanup function when the script exists.
This approach is already used by other existing tests.

[ Upstream commit 436864095a95fcc611c20c44a111985fa9848730 ]
Data passed to user-space with a (SOL_UDP, UDP_GRO) cmsg carries an
int (see udp_cmsg_recv), not a u16 value, as strace confirms:
recvmsg(8, {msg_name=...,
msg_iov=[{iov_base="\0\0..."..., iov_len=96000}],
msg_iovlen=1,
msg_control=[{cmsg_len=20, <-- sizeof(cmsghdr) + 4
cmsg_level=SOL_UDP,
cmsg_type=0x68}], <-- UDP_GRO
msg_controllen=24,
msg_flags=0}, 0) = 11200
Interpreting the data as an u16 value won't work on big-endian platforms.
Since it is too late to back out of this API decision [1], fix the test.

The compiler is optimizing out majority of unref_ptr read/writes, so the test
wasn't testing much. For example, one could delete '__kptr' tag from

[ Upstream commit 0b0757244754ea1d0721195c824770f5576e119e ]
Building BPF selftests out of srctree fails with:
make: *** No rule to make target '/linux-build//ima_setup.sh', needed by 'ima_setup.sh'. Stop.
The culprit is the rule that defines convenient shorthands like
"make test_progs", which builds $(OUTPUT)/test_progs. These shorthands
make sense only for binaries that are built though; scripts that live
in the source tree do not end up in $(OUTPUT).
Therefore drop $(TEST_PROGS) and $(TEST_PROGS_EXTENDED) from the rule.
The issue exists for a while, but it became a problem only after commit
d68ae4982cb7 ("selftests/bpf: Install all required files to run selftests"),
which added dependencies on these scripts.

[ Upstream commit 2514a31241e1e9067d379e0fbdb60e4bc2bf4659 ]
As stated in README.rst, in order to resolve errors with linker errors,
'LDLIBS=-static' should be used. Most problems will be solved by this
option, but in the case of urandom_read, this won't fix the problem. So
the Makefile is currently implemented to strip the 'static' option when
compiling the urandom_read. However, stripping this static option isn't
configured properly on $(LDLIBS) correctly, which is now causing errors
on static compilation.
# LDLIBS=-static ./vmtest.sh
ld.lld: error: attempted static link of dynamic object liburandom_read.so
clang: error: linker command failed with exit code 1 (use -v to see invocation)
make: *** [Makefile:190: /linux/tools/testing/selftests/bpf/urandom_read] Error 1
