The estimated time was supposing the rate was expressed in mibit
(bit * 1024^2) but it is in mbit (bit * 1000^2).
This makes the threshold higher but in a more realistic way to avoid
false positives reported by CI instances.
Before this patch, the thresholds were at 7561/4005ms and now they are
at 7906/4178ms.
While at it, also fix a typo in the linked comment, spotted by Mat.

Not running it from a new netns causes issues if some MPTCP settings are
modified, e.g. if MPTCP is disabled from the sysctl knob, if multiple
addresses are available and added to the MPTCP path-manager, etc.
In these cases, the created connection will not behave as expected, e.g.
unable to create an MPTCP socket, more than one subflow is seen, etc.
A new "sandbox" net namespace is now created and used to run
mptcp_sockopt from this controlled environment.

It's very unusual to have both a command line option and a compile time
option, and apparently that's confusing to people. Also, basically
everybody enables the compile time option now, which means people who
want to disable this wind up having to use the command line option to
ensure that anyway. So just reduce the number of moving pieces and nix
the compile time option in favor of the more versatile command line
option.

The maximum size of ringbuf is 2GB on x86-64 host, so 2 * max_entries
will overflow u32 when mapping producer page and data pages. Only
casting max_entries to size_t is not enough, because for 32-bits
application on 64-bits kernel the size of read-only mmap region
also could overflow size_t.
So fixing it by casting the size of read-only mmap region into a __u64
and checking whether or not there will be overflow during mmap.

Attestation is used to verify the trustworthiness of a TDX guest.
During the guest bring-up, the Intel TDX module measures and records
the initial contents and configuration of the guest, and at runtime,
guest software uses runtime measurement registers (RMTRs) to measure
and record details related to kernel image, command line params, ACPI
tables, initrd, etc. At guest runtime, the attestation process is used
to attest to these measurements.
The first step in the TDX attestation process is to get the TDREPORT
data. It is a fixed size data structure generated by the TDX module
which includes the above mentioned measurements data, a MAC ID to
protect the integrity of the TDREPORT, and a 64-Byte of user specified
data passed during TDREPORT request which can uniquely identify the
TDREPORT.
Intel's TDX guest driver exposes TDX_CMD_GET_REPORT0 IOCTL interface to
enable guest userspace to get the TDREPORT subtype 0.
Add a kernel self test module to test this ABI and verify the validity
of the generated TDREPORT.

In preparation for cxl_acpi walking pci_root->bus->bridge, add that

Note that the missing 3rd entry in mock_pci_root[] was not noticed until
now given that the test version of to_cxl_host_bridge()
(tools/testing/cxl/mock_acpi.c), obviated the need for that entry.
However, "cxl/acpi: Improve debug messages in cxl_acpi_probe()" [1]

This commit tests previous fix of bpf_probe_read_kernel_str().
The BPF helper bpf_probe_read_kernel_str should return -EFAULT when
given a bad source pointer and the target buffer should only be modified
to make the string NULL terminated.
bpf_probe_read_kernel_str() was previously inserting a NULL before the
beginning of the dst buffer. This test should ensure that the
implementation stays correct for now on.
Without the fix, this test will fail as follows:
$ cd tools/testing/selftests/bpf
$ make
$ sudo ./test_progs --name=varlen

"This is a pretty large diffstat for this time of the release. The main
culprit is a reorganization of the AMD assembly trampoline, allowing
percpu variables to be accessed early.
This is needed for the return stack depth tracking retbleed mitigation
that will be in 6.2, but it also makes it possible to tighten the IBRS
restore on vmexit. The latter change is a long tail of the
spectrev2/retbleed patches (the corresponding Intel change was simpler
and went in already last June), which is why I am including it right
now instead of sharing a topic branch with tip.
Being assembly and being rich in comments makes the line count balloon
a bit, but I am pretty confident in the change (famous last words)
because the reorganization actually makes everything simpler and more
understandable than before. It has also had external review and has
been tested on the aforementioned 6.2 changes, which explode quite
brutally without the fix.
Apart from this, things are pretty normal.

If you don't run slabinfo with a superuser, return 0 when read_slab_dir()
reads get_obj_and_str("slabs", &t), because fopen() fails (sometimes
EACCES), causing slabcache() to return directly, without any error during
this time, we should tell the user about the EACCES problem instead of
running successfully($?=0) without any error printing.
For example:
$ ./slabinfo
Permission denied, Try using superuser <== What this submission did
$ sudo ./slabinfo

The first field in /proc/mounts can be influenced by unprivileged users
through the widespread `fusermount` setuid-root program. Example:
```
user$ mkdir ~/mydebugfs
user$ export _FUSE_COMMFD=0
user$ fusermount ~/mydebugfs -ononempty,fsname=debugfs
user$ grep debugfs /proc/mounts
debugfs /home/user/mydebugfs fuse rw,nosuid,nodev,relatime,user_id=1000,group_id=100 0 0
```
If there is no debugfs already mounted in the system then this can be
used by unprivileged users to trick kvm_stat into using a user
controlled file system location for obtaining KVM statistics.
Even though the root user is not allowed to access non-root FUSE mounts
for security reasons, the unprivileged user can unmount the FUSE mount
before kvm_stat uses the mounted path. If it wins the race, kvm_stat
will read from the location where the FUSE mount resided.
Note that the files in debugfs are only opened for reading, so the
attacker can cause very large data to be read in by kvm_stat, or fake
data to be processed, but there should be no viable way to turn this
into a privilege escalation.
The fix is simply to use the file system type field instead. Whitespace
in the mount path is escaped in /proc/mounts thus no further safety
measures in the parsing should be necessary to make this correct.

Along the development cycle, the testing code support for module/in-kernel
compiles was removed. Restore this functionality by moving any internal
API tests to the userspace side, as well as threading tests. Fix the
lockdep issues and add a way to reduce memory usage so the tests can
complete with KASAN + memleak detection. Make the tests work on 32 bit
hosts where possible and detect 32 bit hosts in the radix test suite.

Commit 3af1dfdd51e06697 ("perf build: Move perf_dlfilters.h in the
source tree") moved perf_dlfilters.h to the include/perf/ directory
while include/perf is ignored because it has 'perf' in the name. Newly
created files in the include/perf/ directory will be ignored.
Testing:
Before:
$ touch tools/perf/include/perf/junk
$ git status | grep junk
$ git check-ignore -v tools/perf/include/perf/junk
tools/perf/.gitignore:6:perf tools/perf/include/perf/junk
After:
