The hugepage test cases of iommufd_dirty_tracking have the 64MB and 128MB
coverages. Both of them are smaller than the default hugepage size 512MB,
when CONFIG_PAGE_SIZE_64KB=y. However, these test cases have a variant of
using huge pages, which would mmap(MAP_HUGETLB) using these smaller sizes
than the system hugepag size. This results in the kernel aligning up the
smaller size to 512MB. If a memory was located between the upper 64/128MB
size boundary and the hugepage 512MB boundary, it would get wiped out:
https://lore.kernel.org/all/aEoUhPYIAizTLADq@nvidia.com/
Given that this aligning up behavior is well documented, we have no choice
but to allocate a hugepage aligned size to avoid this unintended wipe out.
Instead of relying on the kernel's internal force alignment, pass the same
size to posix_memalign() and map().
Also, fix the FIXTURE_TEARDOWN() misusing munmap() to free the memory from
posix_memalign(), as munmap() doesn't destroy the allocator meta data. So,
call free() instead.

A new function resetpair() calls close() for the receiver and checks
the return value from recv() on the initial sender side.

We frequently consult with Jesper's out-of-tree page_pool benchmark to
evaluate page_pool changes.
Import the benchmark into the upstream linux kernel tree so that (a)
we're all running the same version, (b) pave the way for shared
improvements, and (c) maybe one day integrate it with nipa, if possible.
Import bench_page_pool_simple from commit 35b1716d0c30 ("Add
page_bench06_walk_all"), from this repository:
https://github.com/netoptimizer/prototype-kernel.git
Changes done during upstreaming:
- Fix checkpatch issues.
- Remove the tasklet logic not needed.
- Move under tools/testing
- Create ksft for the benchmark.
- Changed slightly how the benchmark gets build. Out of tree, time_bench
is built as an independent .ko. Here it is included in
bench_page_pool.ko
Steps to run:
```
mkdir -p /tmp/run-pp-bench
make -C ./tools/testing/selftests/net/bench
make -C ./tools/testing/selftests/net/bench install INSTALL_PATH=/tmp/run-pp-bench
rsync --delete -avz --progress /tmp/run-pp-bench mina@$SERVER:~/
ssh mina@$SERVER << EOF
cd ~/run-pp-bench && sudo ./test_bench_page_pool.sh
EOF
```
Note that by default, the Makefile will build the benchmark for the
currently installed kernel in /lib/modules/$(shell uname -r)/build. To
build against the current tree, do:
make KDIR=$(pwd) -C ./tools/testing/selftests/net/bench
Output (from Jesper):
```
sudo ./test_bench_page_pool.sh
(benchmark dmesg logs snipped)
Fast path results:
no-softirq-page_pool01 Per elem: 23 cycles(tsc) 6.571 ns
ptr_ring results:
no-softirq-page_pool02 Per elem: 60 cycles(tsc) 16.862 ns
slow path results:
no-softirq-page_pool03 Per elem: 265 cycles(tsc) 73.739 ns
```
Output (from me):
```
sudo ./test_bench_page_pool.sh
(benchmark dmesg logs snipped)
Fast path results:
no-softirq-page_pool01 Per elem: 11 cycles(tsc) 4.177 ns
ptr_ring results:
no-softirq-page_pool02 Per elem: 51 cycles(tsc) 19.117 ns
slow path results:
no-softirq-page_pool03 Per elem: 168 cycles(tsc) 62.469 ns
```
Results of course will vary based on hardware/kernel/configs, and some
variance may be there from run to run due to some noise.

XFAIL is considered a form of a pass by our CI. For HW devices returning
XFAIL for unsupported features is counter-productive because our CI
knows not to expect any HW test to pass until it sees 10 passes in a row.
If we return xfail the test shows up as pass even if the device doesn't
support the feature. netdevsim supports all features necessary for
the stats test so there is no concern about running the test in SW mode.
Make the test skip rather than xfail if driver doesn't support FEC or pause.

Expand the SKIP conditions of the open_path_or_exit() helper to skip on

not because of any bug/misconfiguration that warrants failing a test.

Add an inner __open_path_or_exit() API to let the caller provide additional

access tracking perf, which is dependent on a Kconfig.
Immediately convert /dev/kvm to the new API, both as an example and because

- A protected map that only allows read-only access
- An unprotected map that allows full access
The test script attaches the BPF program to security_bpf_map and
verifies that for the bpftool map command:
- Read access works on both maps
- Write access fails on the protected map
- Write access succeeds on the unprotected map
- These behaviors remain consistent when the maps are pinned

Sometimes the vxlan vnifiltering test failed on slow machines due to
network setup not finished. e.g.
TEST: VM connectivity over vnifiltering vxlan (ipv4 default rdst) [ OK ]
TEST: VM connectivity over vnifiltering vxlan (ipv6 default rdst) [FAIL]
Let's use slowwait to make sure the connection is finished.

The vrf_route_leaking test occasionally fails due to connectivity issues
in our testing environment. A sample failure message shows that the ping
check fails intermittently
PING 2001:db8:16:2::2 (2001:db8:16:2::2) 56 data bytes
--- 2001:db8:16:2::2 ping statistics ---
1 packets transmitted, 0 received, 100% packet loss, time 0ms
TEST: Basic IPv6 connectivity [FAIL]
This is likely due to insufficient wait time on slower machines. To address
this, switch to using slowwait, which provides a longer and more reliable
wait for setup completion.
Before this change, the test failed 3 out of 10 times. After applying this
fix, the test was run 30 times without any failure.
