[ Upstream commit 4fb877aaa1 ]
Fix bug in btf_dump's logic of determining if a given struct type is
packed or not. The notion of "natural alignment" is not needed and is
even harmful in this case, so drop it altogether. The biggest difference
in btf_is_struct_packed() compared to its original implementation is
that we don't really use btf__align_of() to determine overall alignment
of a struct type (because it could be 1 for both packed and non-packed
struct, depending on specifci field definitions), and just use field's
actual alignment to calculate whether any field is requiring packing or
struct's size overall necessitates packing.
Add two simple test cases that demonstrate the difference this change
would make.

[ Upstream commit ea2ce1ba99 ]
Turns out that btf_dump API doesn't handle a bunch of tricky corner
cases, as reported by Per, and further discovered using his testing
Python script ([0]).
This patch revamps btf_dump's padding logic significantly, making it
more correct and also avoiding unnecessary explicit padding, where
compiler would pad naturally. This overall topic turned out to be very
tricky and subtle, there are lots of subtle corner cases. The comments
in the code tries to give some clues, but comments themselves are
supposed to be paired with good understanding of C alignment and padding
rules. Plus some experimentation to figure out subtle things like
whether `long :0;` means that struct is now forced to be long-aligned
(no, it's not, turns out).
Anyways, Per's script, while not completely correct in some known
situations, doesn't show any obvious cases where this logic breaks, so
this is a nice improvement over the previous state of this logic.
Some selftests had to be adjusted to accommodate better use of natural
alignment rules, eliminating some unnecessary padding, or changing it to
`type: 0;` alignment markers.
Note also that for when we are in between bitfields, we emit explicit
bit size, while otherwise we use `: 0`, this feels much more natural in
practice.
Next patch will add few more test cases, found through randomized Per's
script.

[ Upstream commit ca22da2fbd ]
William reports kernel soft-lockups on some OVS topologies when TC mirred
egress->ingress action is hit by local TCP traffic [1].
The same can also be reproduced with SCTP (thanks Xin for verifying), when
client and server reach themselves through mirred egress to ingress, and
one of the two peers sends a "heartbeat" packet (from within a timer).
Enqueueing to backlog proved to fix this soft lockup; however, as Cong
noticed [2], we should preserve - when possible - the current mirred
behavior that counts as "overlimits" any eventual packet drop subsequent to
the mirred forwarding action [3]. A compromise solution might use the
backlog only when tcf_mirred_act() has a nest level greater than one:
change tcf_mirred_forward() accordingly.
Also, add a kselftest that can reproduce the lockup and verifies TC mirred
ability to account for further packet drops after TC mirred egress->ingress
(when the nest level is 1).

[2] https://lore.kernel.org/netdev/Y0w%2FWWY60gqrtGLp@pop-os.localdomain/
[3] such behavior is not guaranteed: for example, if RPS or skb RX
timestamping is enabled on the mirred target device, the kernel
can defer receiving the skb and return NET_RX_SUCCESS inside
tcf_mirred_forward().

[ Upstream commit b69245126a ]
Since commit 6c40624930 ("bootconfig: Increase max nodes of bootconfig
from 1024 to 8192 for DCC support") increased the max number of bootconfig
node to 8192, the bootconfig testcase of the max number of nodes fails.
To fix this issue, we can not simply increase the number in the test script
because the test bootconfig file becomes too big (>32KB). To fix that, we
can use a combination of three alphabets (26^3 = 17576). But with that,
we can not express the 8193 (just one exceed from the limitation) because
it also exceeds the max size of bootconfig. So, the first 26 nodes will just
use one alphabet.
With this fix, test-bootconfig.sh passes all tests.

[ Upstream commit 6c20822fad ]
&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)

When creating counters with initial delay configured, the enable_on_exec
field is not set. So we need to enable the counters later. The problem
is, when a workload is specified the target__none() is true. So we also
need to check stat_config.initial_delay.
In this change, we add a new field 'initial_delay' for struct target
which could be shared by other subcommands. And define
target__enable_on_exec() which returns whether enable_on_exec should be
set on normal cases.

commit ce9f1c05d2 upstream.
When MMAP2 has the PERF_RECORD_MISC_MMAP_BUILD_ID flag, it means the
record already has the build-id info. So it marks the DSO as hit, to
skip if the same DSO is not processed if it happens to miss the build-id
later.
But it missed to copy the MMAP2 record itself so it'd fail to symbolize
samples for those regions.
For example, the following generates 249 MMAP2 events.
$ perf record --buildid-mmap -o- true | perf report --stat -i- | grep MMAP2
MMAP2 events: 249 (86.8%)
Adding perf inject should not change the number of events like this
$ perf record --buildid-mmap -o- true | perf inject -b | \
> perf report --stat -i- | grep MMAP2
MMAP2 events: 249 (86.5%)
But when --buildid-all is used, it eats most of the MMAP2 events.
$ perf record --buildid-mmap -o- true | perf inject -b --buildid-all | \
> perf report --stat -i- | grep MMAP2
MMAP2 events: 1 ( 2.5%)
With this patch, it shows the original number now.
$ perf record --buildid-mmap -o- true | perf inject -b --buildid-all | \
> perf report --stat -i- | grep MMAP2
MMAP2 events: 249 (86.5%)
Committer testing:
Before:
$ perf record --buildid-mmap -o- perf stat --null sleep 1 2> /dev/null | perf inject -b | perf report --stat -i- | grep MMAP2
MMAP2 events: 58 (36.2%)
$ perf record --buildid-mmap -o- perf stat --null sleep 1 2> /dev/null | perf report --stat -i- | grep MMAP2

commit 4e7d2a8f0b upstream.
There is a disconnect between the run_command function and the
wait_for_input. The wait_for_input has a default timeout of 2 minutes. But
if that happens, the run_command loop will exit out to the waitpid() of
the executing command. This fails in that it no longer monitors the
command, and also, the ssh to the test box can hang when its finished, as
it's waiting for the pipe it's writing to to flush, but the loop that
reads that pipe has already exited, leaving the command stuck, and the
test hangs.
Instead, make the default "wait_for_input" of the run_command infinite,
and allow the user to override it if they want with a default timeout
option "RUN_TIMEOUT".
But this fixes the hang that happens when the pipe is full and the ssh
session never exits.
