Sometimes more than one variables are located in the same register or a
stack slot. Or it can overwrite existing information with others. I
found this is not helpful in some cases so it needs to update the type
information from the variable only if it's better.
But it's hard to know which one is better, so we needs heuristics. :)
As it deals with memory accesses, the location should have a pointer or
something similar (like array or reference). So if it had an integer
type and a variable is a pointer, we can take the variable's type to
resolve the target of the access.
If it has a pointer type and a variable with the same location has a
different pointer type, it'll take one with bigger target type. This
can be useful when the target type embeds a smaller type (like list
header or RB-tree node) at the beginning so their location is same.

It treats pointers and arrays in the same way. Let's add the helper and
use it when it checks if it needs a pointer.

So that it can return enum variable_match_type to be propagated to the
find_data_type_die(). Also update the debug message to show the result
of the check_matching_type().

The location list will have entries with half-open addressing like
[start, end) which means it doesn't include the end address. So it
should skip entries at the end address and match to the next entry.
An example location list looks like this (from readelf -wo):
00237876 ffffffff8110d32b (base address)
0023787f v000000000000000 v000000000000002 views at 00237868 for:

ffffffff8110d876 ffffffff8110d88e (DW_OP_reg3 (rbx))
The first entry at 0023787f has [8110d32b, 8110d4eb) (omitting the
ffffffff at the beginning), and the second one has [8110d4eb, 8110d50b).

It missed to call check_allowed_ops() in __die_collect_vars_cb() so it
can take variables with complex location expression incorrectly.
For example, I found some variable has this expression.

DW_OP_lit1; DW_OP_shra; DW_OP_const1u: 64;
DW_OP_minus; DW_OP_stack_value)
015d8e2c <End of list>
It looks like '((int *)(-176(%rbp) + 332) >> 1) - 64' but the current
code thought it's just -176(%rbp) and processed the variable incorrectly.
It should reject such a complex expression if check_allowed_ops()
doesn't like it. :)

hand, the current test is failed due to loading the XDP program. e.g.

Add a test for the new functionality of userspace-driven timers and the
tool which allows us to count timer ticks in a certain time period. The
test:
1. Creates a userspace-driven timer with ioctl to /dev/snd/timer
2. Starts the `global-timer` application to count the ticks of the timer
from step 1.
3. Asynchronously triggers the timer multiple times with some interval
4. Compares the amount of caught ticks with the amount of trigger calls.
Since we can't include <alsa/asoundlib.h> and <sound/asound.h> in one
file due to overlapping declarations, I have to split the test into two
applications: one of them counts the amount of timer ticks in the
defined time period, and another one is the actual test which creates
the timer, triggers it periodically and starts the first app to count
the amount of ticks in a separate thread.
Besides from testing the functionality itself, the test represents a
sample application showing userspace-driven ALSA timers API.
Also, the timer test includes a test case which tries to create a timer
with invalid resolution (=0), and NULL as a timer info structure.

During LTO the references from the compiler-generated prologue and
epilogues to the stack protector symbols are not visible and the symbols
are removed.
This will then lead to errors during linking.
As those symbols are already #ifdeffed-out if unused mark them as "used"

The bridge VLAN implementation w.r.t. VLAN protocol is described in
merge commit 1a0b20b25732 ("Merge branch 'bridge-next'"). We are only
sensitive to those VLAN tags whose TPID is equal to the bridge's
vlan_protocol. Thus, an 802.1ad VLAN should be treated as 802.1Q-untagged.
Add 3 tests which validate that:
- 802.1ad-tagged traffic is learned into the PVID of an 802.1Q-aware
bridge
- Double-tagged traffic is forwarded when just the PVID of the port is
present in the VLAN group of the ports
- Double-tagged traffic is not forwarded when the PVID of the port is
absent from the VLAN group of the ports
The test passes with both veth and ocelot.

A breakage in the felix DSA driver shows we do not have enough test
coverage. More generally, it is sufficiently special that it is likely
drivers will treat it differently.
This is not meant to be a full PTP test, it just makes sure that PTP
packets sent to the different addresses corresponding to their profiles
are received correctly. The local_termination selftest seemed like the
most appropriate place for this addition.
PTP RX/TX in some cases makes no sense (over a bridge) and this is why
$skip_ptp exists. And in others - PTP over a bridge port - the IP stack
needs convincing through the available bridge netfilter hooks to leave
the PTP packets alone and not stolen by the bridge rx_handler. It is
safe to assume that users have that figured out already. This is a
driver level test, and by using tcpdump, all that extra setup is out of
scope here.
send_non_ip() was an unfinished idea; written but never used.
Replace it with a more generic send_raw(), and send 3 PTP packet types
times 3 transports.

xfail_on_veth() for this test is an incorrect approximation which gives
false positives and false negatives.
When local_termination fails with "reception succeeded, but should have failed",
it is because the DUT ($h2) accepts packets even when not configured as
promiscuous. This is not something specific to veth; even the bridge
behaves that way, but this is not captured by the xfail_on_veth test.
The IFF_UNICAST_FLT flag is not explicitly exported to user space, but
it can somewhat be determined from the interface's behavior. We have to
create a macvlan upper with a different MAC address. This forces a
dev_uc_add() call in the kernel. When the unicast filtering list is
not empty, but the device doesn't support IFF_UNICAST_FLT,
__dev_set_rx_mode() force-enables promiscuity on the interface, to
ensure correct behavior (that the requested address is received).
We can monitor the change in the promiscuity flag and infer from it
whether the device supports unicast filtering.
There is no equivalent thing for allmulti, unfortunately. We never know
what's hiding behind a device which has allmulti=off. Whether it will
actually perform RX multicast filtering of unknown traffic is a strong
"maybe". The bridge driver, for example, completely ignores the flag.
We'll have to keep the xfail behavior, but instead of XFAIL on just
veth, always XFAIL.

Add more coverage to the local termination selftest as follows:
- 8021q upper of $h2
- 8021q upper of $h2, where $h2 is a port of a VLAN-unaware bridge
- 8021q upper of $h2, where $h2 is a port of a VLAN-aware bridge
- 8021q upper of VLAN-unaware br0, which is the upper of $h2
- 8021q upper of VLAN-aware br0, which is the upper of $h2
Especially the cases with traffic sent through the VLAN upper of a
VLAN-aware bridge port will be immediately relevant when we will start
transmitting PTP packets as an additional kind of traffic.

The current bridge() test is for packet reception on a VLAN-unaware
bridge. Some things are different enough with VLAN-aware bridges that
it's worth renaming this test into vlan_unaware_bridge(), and add a new
vlan_aware_bridge() test.
The two will share the same implementation: bridge() becomes a common
function, which receives $vlan_filtering as an argument. Rename it to
test_bridge() at the same time, because just bridge() pollutes the
global namespace and we cannot invoke the binary with the same name from
the iproute2 package currently.

There are upcoming tests which verify the RX filtering of a bridge
(or bridge port), but under differing vlan_filtering conditions.

In future changes we will want to subject the DUT, $h2, to additional
VLAN-tagged traffic. For that, we need to run the tests using $h1.100 as
a sending interface, rather than the currently hardcoded $h1.
Add a parameter to run_test() and modify its 2 callers to explicitly
pass $h1, as was implicit before.

[1] mentions that memfd_secret is only supported on arm64, riscv, x86 and
x86_64 for now. It doesn't support other architectures. I found the
build error on arm and decided to send the fix as it was creating noise on
KernelCI:
memfd_secret.c: In function 'memfd_secret':
memfd_secret.c:42:24: error: '__NR_memfd_secret' undeclared (first use in this function);
did you mean 'memfd_secret'?
42 | return syscall(__NR_memfd_secret, flags);
| ^~~~~~~~~~~~~~~~~
| memfd_secret
Hence I'm adding condition that memfd_secret should only be compiled on
supported architectures.
Also check in run_vmtests script if memfd_secret binary is present before
executing it.

In reality, our use is fine, it's just that GCC doesn't model errno

by initializing elf_fd.fd to -1 and elf_fd.elf to NULL.
I've done this in two other functions as well given it could easily
occur there too (same access/use pattern).

The fixdep binary is being compiled and linked in one step. While the
host linker flags are passed to the compiler the host compiler flags are
missed.
That leads to build errors at least on x86_64, arm64 and s390 as result
of the compiler vs linker flags inconsistency. For example, during RPM
package build redhat-hardened-ld script is provided to gcc, while
redhat-hardened-cc1 script is missed.
Provide both KBUILD_HOSTCFLAGS and KBUILD_HOSTLDFLAGS to avoid that.

the symbol objects were leaked until c087e9480cf33672 ("perf machine:

reasm, from Tom Hughes.
2) Initialize extack for begin/end netlink message marker in batch,
from Donald Hunter.
3) Initialize extack for flowtable offload support, also from Donald.
4) Dropped packets with cloned unconfirmed conntracks in nfqueue,
later it should be possible to explore lookup after reinject but
Florian prefers this approach at this stage. From Florian Westphal.
5) Add selftest for cloned unconfirmed conntracks in nfqueue for
previous update.
6) Audit after filling netlink header successfully in object dump,
from Phil Sutter.
7-8) Fix concurrent dump and reset which could result in underflow
counter / quota objects.
