commit 1a4ea83a6e67f1415a1f17c1af5e9c814c882bb5 upstream.
While sched* events being traced and sched* events continuously happen,
"[xx] event tracing - enable/disable with subsystem level files" would
not stop as on some slower systems it seems to take forever.
Select the first 100 lines of output would be enough to judge whether
there are more than 3 types of sched events.

[ Upstream commit 4e6500bfa053dc133021f9c144261b77b0ba7dc8 ]
Replace seekdir() with rewinddir() in order to fix a localized glibc bug.
One of the glibc patches that stable Gentoo is using causes an improper
directory stream positioning bug on 32bit arm. That in turn ends up as a
floating point exception in iio_generic_buffer.
The attached patch provides a fix by using an equivalent function which
should not cause trouble for other distros and is easier to reason about
in general as it obviously always goes back to to the start.

The test type "make_warnings_file" should have no mandatory configuration
parameters other than the ones required by the "build" test type, because
its purpose is to create a file with build warnings that may or may not be
used by other subsequent tests. Currently, the only way to use it as a
stand-alone test is by setting POWER_CYCLE, CONSOLE, SSH_USER,
BUILD_TARGET, TARGET_IMAGE, REBOOT_TYPE and GRUB_MENU.

commit 7a1b3490f47e88ec4cbde65f1a77a0f4bc972282 upstream.
Current MPTCP servers increment MPTcpExtMPCapableFallbackACK when they
accept non-MPC connections. As reported by Christoph, this is "surprising"
because the counter might become greater than MPTcpExtMPCapableSYNRX.
MPTcpExtMPCapableFallbackACK counter's name suggests it should only be
incremented when a connection was seen using MPTCP options, then a
fallback to TCP has been done. Let's do that by incrementing it when
the subflow context of an inbound MPC connection attempt is dropped.
Also, update mptcp_connect.sh kselftest, to ensure that the
above MIB does not increment in case a pure TCP client connects to a
MPTCP server.

The .BTF_ids section is pre-filled with zeroed BTF ID entries during the
build and afterwards patched by resolve_btfids with correct values.
Since resolve_btfids always writes in host-native endianness, it relies
on libelf to do the translation when the target ELF is cross-compiled to
a different endianness (this was introduced in commit 61e8aeda9398
("bpf: Fix libelf endian handling in resolv_btfids")).
Unfortunately, the translation will corrupt the flags fields of SET8
entries because these were written during vmlinux compilation and are in
the correct endianness already. This will lead to numerous selftests
failures such as:
$ sudo ./test_verifier 502 502
#502/p sleepable fentry accept FAIL
Failed to load prog 'Invalid argument'!
bpf_fentry_test1 is not sleepable
verification time 34 usec
stack depth 0
processed 0 insns (limit 1000000) max_states_per_insn 0 total_states 0 peak_states 0 mark_read 0
Summary: 0 PASSED, 0 SKIPPED, 1 FAILED
Since it's not possible to instruct libelf to translate just certain
values, let's manually bswap the flags (both global and entry flags) in
resolve_btfids when needed, so that libelf then translates everything
correctly.

There exists the following warning when building bpftool:

prog.c: In function ‘profile_open_perf_events’:

prog.c:2301:24: note: earlier argument should specify number of elements, later size of each element
Tested with the latest upstream GCC which contains a new warning option
-Wcalloc-transposed-args. The first argument to calloc is documented to
be number of elements in array, while the second argument is size of each
element, just switch the first and second arguments of calloc() to silence
the build warning, compile tested only.

When running the simult_flow selftest in slow environments -- e.g. QEmu
without KVM support --, the results can be unstable. This selftest
checks if the aggregated bandwidth is (almost) fully used as expected.
To help improving the stability while still keeping the same validation
in place, the BW and the delay are reduced to lower the pressure on the
CPU.

On systems with 64k page size and 512M huge page sizes, the allocation and
test succeeds but errors out at the munmap. As the comment states, munmap
will failure if its not HUGEPAGE aligned. This is due to the length of
the mapping being 1/2 the size of the hugepage causing the munmap to not
be hugepage aligned. Fix this by making the mapping length the full
hugepage if the hugepage is larger than the length of the mapping.

commit dab4e1f06cabb6834de14264394ccab197007302 upstream.
Extend the bpf_fib_lookup() helper by making it to return the source
IPv4/IPv6 address if the BPF_FIB_LOOKUP_SRC flag is set.
For example, the following snippet can be used to derive the desired
source IP address:
struct bpf_fib_lookup p = { .ipv4_dst = ip4->daddr };
ret = bpf_skb_fib_lookup(skb, p, sizeof(p),
BPF_FIB_LOOKUP_SRC | BPF_FIB_LOOKUP_SKIP_NEIGH);
if (ret != BPF_FIB_LKUP_RET_SUCCESS)
return TC_ACT_SHOT;
/* the p.ipv4_src now contains the source address */
The inability to derive the proper source address may cause malfunctions
in BPF-based dataplanes for hosts containing netdevs with more than one
routable IP address or for multi-homed hosts.
For example, Cilium implements packet masquerading in BPF. If an
egressing netdev to which the Cilium's BPF prog is attached has
multiple IP addresses, then only one [hardcoded] IP address can be used for
masquerading. This breaks connectivity if any other IP address should have
been selected instead, for example, when a public and private addresses
are attached to the same egress interface.
The change was tested with Cilium [1].
Nikolay Aleksandrov helped to figure out the IPv6 addr selection.

commit 8ad77e72caae22a1ddcfd0c03f2884929e93b7a4 upstream.
Add ability to specify routing table ID to the `bpf_fib_lookup` BPF
helper.
A new field `tbid` is added to `struct bpf_fib_lookup` used as
parameters to the `bpf_fib_lookup` BPF helper.
When the helper is called with the `BPF_FIB_LOOKUP_DIRECT` and
`BPF_FIB_LOOKUP_TBID` flags the `tbid` field in `struct bpf_fib_lookup`
will be used as the table ID for the fib lookup.
If the `tbid` does not exist the fib lookup will fail with
`BPF_FIB_LKUP_RET_NOT_FWDED`.
The `tbid` field becomes a union over the vlan related output fields
in `struct bpf_fib_lookup` and will be zeroed immediately after usage.
This functionality is useful in containerized environments.
For instance, if a CNI wants to dictate the next-hop for traffic leaving
a container it can create a container-specific routing table and perform
a fib lookup against this table in a "host-net-namespace-side" TC program.
This functionality also allows `ip rule` like functionality at the TC
layer, allowing an eBPF program to pick a routing table based on some
aspect of the sk_buff.
As a concrete use case, this feature will be used in Cilium's SRv6 L3VPN
datapath.
When egress traffic leaves a Pod an eBPF program attached by Cilium will
determine which VRF the egress traffic should target, and then perform a
FIB lookup in a specific table representing this VRF's FIB.

commit 483ae90d8f976f8339cf81066312e1329f2d3706 upstream.
When tc filters are first added to a net device, the corresponding local
port gets bound to an ACL group in the device. The group contains a list
of ACLs. In turn, each ACL points to a different TCAM region where the
filters are stored. During forwarding, the ACLs are sequentially
evaluated until a match is found.
One reason to place filters in different regions is when they are added
with decreasing priorities and in an alternating order so that two
consecutive filters can never fit in the same region because of their
key usage.
In Spectrum-2 and newer ASICs the firmware started to report that the
maximum number of ACLs in a group is more than 16, but the layout of the
register that configures ACL groups (PAGT) was not updated to account
for that. It is therefore possible to hit stack corruption [1] in the
rare case where more than 16 ACLs in a group are required.
Fix by limiting the maximum ACL group size to the minimum between what
the firmware reports and the maximum ACLs that fit in the PAGT register.
Add a test case to make sure the machine does not crash when this
condition is hit.

[ Upstream commit 52e63d67b5bb423b33d7a262ac7f8bd375a90145 ]
In order for the page table level 5 to be in use, the CPU must have the
setting enabled in addition to the CONFIG option. Check for the flag to be
set to avoid false test failures on systems that do not have this cpu flag
set.
The test does a series of mmap calls including three using the
MAP_FIXED flag and specifying an address that is 1<<47 or 1<<48. These
addresses are only available if you are using level 5 page tables,
which requires both the CPU to have the capabiltiy (la57 flag) and the
kernel to be configured. Currently the test only checks for the kernel
configuration option, so this test can still report a false positive.
Here are the three failing lines:
$ ./va_high_addr_switch | grep FAILED
mmap(ADDR_SWITCH_HINT, 2 * PAGE_SIZE, MAP_FIXED): 0xffffffffffffffff - FAILED
mmap(HIGH_ADDR, MAP_FIXED): 0xffffffffffffffff - FAILED
mmap(ADDR_SWITCH_HINT, 2 * PAGE_SIZE, MAP_FIXED): 0xffffffffffffffff - FAILED
I thought (for about a second) refactoring the test so that these three
mmap calls will only be run on systems with the level 5 page tables
available, but the whole point of the test is to check the level 5
feature...

setting it past the end of the mmapped area due to not taking the pointer
alignment into consideration. Fix this behaviour.
Up until commit efa7df3e3bb5 ("mm: align larger anonymous mappings on THP

alignment difference was always less than PMD-size. But since the
mentioned commit, `ksm_tests -H -s 100` started failing.

On very slow environments -- e.g. when QEmu is used without KVM --,
mptcp_join.sh selftest can take a bit more than 20 minutes. Bump the
default timeout by 50% as it seems normal to take that long on some
environments.
When a debug kernel config is used, this selftest will take even longer,
but that's certainly not a common test env to consider for the timeout.
The Fixes tag that has been picked here is there simply to help having
this patch backported to older stable versions. It is difficult to point
to the exact commit that made some env reaching the timeout from time to
time.

commit 3645c844902bd4e173d6704fc2a37e8746904d67 upstream.
Since the commit mentioned below, 'mptcp_join' selftests is using
IPTables to add rules to the Filter table.

This KConfig is usually enabled by default in many defconfig, but we
recently noticed that some CI were running our selftests without them
enabled.
