selftests: ftrace: Add inter-event hist triggers testcases
This adds inter-event hist triggers testcases which covers following:
- create/remove synthetic event
- disable histogram for synthetic event
- extended error support
- field variable support
- histogram variables
- histogram trigger onmatch action
- histogram trigger onmax action
- histogram trigger onmatch-onmax action
- simple expression support
- combined histogram
Here is the test result.
=== Ftrace unit tests ===
[1] event trigger - test extended error support [PASS]
[2] event trigger - test field variable support [PASS]
[3] event trigger - test inter-event combined histogram trigger [PASS]
[4] event trigger - test inter-event histogram trigger onmatch action [PASS]
[5] event trigger - test inter-event histogram trigger onmatch-onmax action [PASS]
[6] event trigger - test inter-event histogram trigger onmax action [PASS]
[7] event trigger - test synthetic event create remove [PASS]

selftests/x86: Add validity check and allow field splitting
[ Upstream commit b06e15ebd5bfb670f93c7f11a29b8299c1178bc6 ]
Add check to test if CC has a string. CC can have multiple sub-strings
like "ccache gcc". Erorr pops up if it is treated as single string and
double quotes are used around it. This can be fixed by removing the
quotes and not treating CC as a single string.

kselftest/vm: fix tests build with old libc
[ Upstream commit b773827e361952b3f53ac6fa4c4e39ccd632102e ]
The error message when I build vm tests on debian10 (GLIBC 2.28):
userfaultfd.c: In function `userfaultfd_pagemap_test':
userfaultfd.c:1393:37: error: `MADV_PAGEOUT' undeclared (first use
in this function); did you mean `MADV_RANDOM'?
if (madvise(area_dst, test_pgsize, MADV_PAGEOUT))
^~~~~~~~~~~~
MADV_RANDOM
This patch includes these newer definitions from UAPI linux/mman.h, is
useful to fix tests build on systems without these definitions in glibc
sys/mman.h.

selftests/memfd: clean up mapping in mfd_fail_write
[ Upstream commit fda153c89af344d21df281009a9d046cf587ea0f ]
Running the memfd script ./run_hugetlbfs_test.sh will often end in error
as follows:
memfd-hugetlb: CREATE
memfd-hugetlb: BASIC
memfd-hugetlb: SEAL-WRITE
memfd-hugetlb: SEAL-FUTURE-WRITE
memfd-hugetlb: SEAL-SHRINK
fallocate(ALLOC) failed: No space left on device
./run_hugetlbfs_test.sh: line 60: 166855 Aborted (core dumped) ./memfd_test hugetlbfs
opening: ./mnt/memfd
fuse: DONE
If no hugetlb pages have been preallocated, run_hugetlbfs_test.sh will
allocate 'just enough' pages to run the test. In the SEAL-FUTURE-WRITE
test the mfd_fail_write routine maps the file, but does not unmap. As a
result, two hugetlb pages remain reserved for the mapping. When the
fallocate call in the SEAL-SHRINK test attempts allocate all hugetlb
pages, it is short by the two reserved pages.
Fix by making sure to unmap in mfd_fail_write.

selftests/zram: Adapt the situation that /dev/zram0 is being used
[ Upstream commit 01dabed20573804750af5c7bf8d1598a6bf7bf6e ]
If zram-generator package is installed and works, then we can not remove
zram module because zram swap is being used. This case needs a clean zram
environment, change this test by using hot_add/hot_remove interface. So
even zram device is being used, we still can add zram device and remove
them in cleanup.
The two interface was introduced since kernel commit 6566d1a32bf7("zram:
add dynamic device add/remove functionality") in v4.2-rc1. If kernel
supports these two interface, we use hot_add/hot_remove to slove this
problem, if not, just check whether zram is being used or built in, then
skip it on old kernel.

selftests/zram01.sh: Fix compression ratio calculation
[ Upstream commit d18da7ec3719559d6e74937266d0416e6c7e0b31 ] zram01 uses `free -m` to measure zram memory usage. The results are no sense because they are polluted by all running processes on the system. We Should only calculate the free memory delta for the current process. So use the third field of /sys/block/zram<id>/mm_stat to measure memory usage instead. The file is available since kernel 4.1. orig_data_size(first): uncompressed size of data stored in this disk. compr_data_size(second): compressed size of data stored in this disk mem_used_total(third): the amount of memory allocated for this disk Also remove useless zram cleanup call in zram_fill_fs and so we don't need to cleanup zram twice if fails.

selftests: futex: Use variable MAKE instead of make
commit b9199181a9ef8252e47e207be8c23e1f50662620 upstream.
Recursive make commands should always use the variable MAKE, not the
explicit command name ‘make’. This has benefits and removes the
following warning when multiple jobs are used for the build:
make[2]: warning: jobserver unavailable: using -j1. Add '+' to parent make rule.

[...]
After scrubbing the BPF prog a bit from the noise, turns out it called
bpf_skb_change_head() for the lwt_xmit prog with headroom of 2. Nothing
wrong in that, however, this was run with repeat >> 0 in bpf_prog_test_run_skb()
and the same skb thus keeps changing until the pskb_expand_head() called
from skb_cow() keeps bailing out in atomic alloc context with -ENOMEM.
So upon return we'll basically have 0 headroom left yet blindly do the
__skb_push() of 14 bytes and keep copying data from there in bpf_test_finish()
out of bounds. Fix to check if we have enough headroom and if pskb_expand_head()
fails, bail out with error.
Another bug independent of this fix (but related in triggering above) is
that BPF_PROG_TEST_RUN should be reworked to reset the skb/xdp buffer to
it's original state from input as otherwise repeating the same test in a
loop won't work for benchmarking when underlying input buffer is getting
changed by the prog each time and reused for the next run leading to
unexpected results.

wireguard: device: reset peer src endpoint when netns exits
Each peer's endpoint contains a dst_cache entry that takes a reference to another netdev. When the containing namespace exits, we take down the socket and prevent future sockets from being created (by setting creating_net to NULL), which removes that potential reference on the netns. However, it doesn't release references to the netns that a netdev cached in dst_cache might be taking, so the netns still might fail to exit. Since the socket is gimped anyway, we can simply clear all the dst_caches (by way of clearing the endpoint src), which will release all references. However, the current dst_cache_reset function only releases those references lazily. But it turns out that all of our usages of wg_socket_clear_peer_endpoint_src are called from contexts that are not exactly high-speed or bottle-necked. For example, when there's connection difficulty, or when userspace is reconfiguring the interface. And in particular for this patch, when the netns is exiting. So for those cases, it makes more sense to call dst_release immediately. For that, we add a small helper function to dst_cache. This patch also adds a test to netns.sh from Hangbin Liu to ensure this doesn't regress.

selftests/bpf: Enlarge select() timeout for test_maps
[ Upstream commit 2d82d73da35b72b53fe0d96350a2b8d929d07e42 ] 0Day robot observed that it's easily timeout on a heavy load host. ------------------- # selftests: bpf: test_maps # Fork 1024 tasks to 'test_update_delete' # Fork 1024 tasks to 'test_update_delete' # Fork 100 tasks to 'test_hashmap' # Fork 100 tasks to 'test_hashmap_percpu' # Fork 100 tasks to 'test_hashmap_sizes' # Fork 100 tasks to 'test_hashmap_walk' # Fork 100 tasks to 'test_arraymap' # Fork 100 tasks to 'test_arraymap_percpu' # Failed sockmap unexpected timeout not ok 3 selftests: bpf: test_maps # exit=1 # selftests: bpf: test_lru_map # nr_cpus:8 ------------------- Since this test will be scheduled by 0Day to a random host that could have only a few cpus(2-8), enlarge the timeout to avoid a false NG report. In practice, i tried to pin it to only one cpu by 'taskset 0x01 ./test_maps', and knew 10S is likely enough, but i still perfer to a larger value 30.

UPSTREAM: wireguard: device: avoid circular netns references
Before, we took a reference to the creating netns if the new netns was
different. This caused issues with circular references, with two
wireguard interfaces swapping namespaces. The solution is to rather not
take any extra references at all, but instead simply invalidate the
creating netns pointer when that netns is deleted.
In order to prevent this from happening again, this commit improves the
rough object leak tracking by allowing it to account for created and
destroyed interfaces, aside from just peers and keys. That then makes it
possible to check for the object leak when having two interfaces take a
reference to each others' namespaces.

UPSTREAM: wireguard: socket: remove errant restriction on looping to self
It's already possible to create two different interfaces and loop
packets between them. This has always been possible with tunnels in the
kernel, and isn't specific to wireguard. Therefore, the networking stack
already needs to deal with that. At the very least, the packet winds up
exceeding the MTU and is discarded at that point. So, since this is
already something that happens, there's no need to forbid the not very
exceptional case of routing a packet back to the same interface; this
loop is no different than others, and we shouldn't special case it, but
rather rely on generic handling of loops in general. This also makes it
easier to do interesting things with wireguard such as onion routing.
At the same time, we add a selftest for this, ensuring that both onion
routing works and infinite routing loops do not crash the kernel. We
also add a test case for wireguard interfaces nesting packets and
sending traffic between each other, as well as the loop in this case
too. We make sure to send some throughput-heavy traffic for this use
case, to stress out any possible recursion issues with the locks around
workqueues.

UPSTREAM: wireguard: noise: error out precomputed DH during handshake rather than config
We precompute the static-static ECDH during configuration time, in order to save an expensive computation later when receiving network packets. However, not all ECDH computations yield a contributory result. Prior, we were just not letting those peers be added to the interface. However, this creates a strange inconsistency, since it was still possible to add other weird points, like a valid public key plus a low-order point, and, like points that result in zeros, a handshake would not complete. In order to make the behavior more uniform and less surprising, simply allow all peers to be added. Then, we'll error out later when doing the crypto if there's an issue. This also adds more separation between the crypto layer and the configuration layer. Discussed-with: Mathias Hall-Andersen <mathias@hall-andersen.dk> Signed-off-by: Jason A.

UPSTREAM: wireguard: selftests: remove ancient kernel compatibility code
Quite a bit of the test suite was designed to work with ancient kernels. Thankfully we no longer have to deal with this. This commit updates things that we can finally update and removes things that we can finally remove, to avoid the build-up of the last several years as a result of having to support ancient kernels. We can finally rely on suppress_ prefixlength being available. On the build side of things, the no-PIE hack is no longer required, and we can bump some of the tools, repair our m68k and i686-kvm support, and get better coverage of the static branches used in the crypto lib and in udp_tunnel.

UPSTREAM: wireguard: selftests: import harness makefile for test suite
WireGuard has been using this on build.wireguard.com for the last several years with considerable success. It allows for very quick and iterative development cycles, and supports several platforms. To run the test suite on your current platform in QEMU: $ make -C tools/testing/selftests/wireguard/qemu -j$(nproc) To run it with KASAN and such turned on: $ DEBUG_KERNEL=yes make -C tools/testing/selftests/wireguard/qemu -j$(nproc) To run it emulated for another platform in QEMU: $ ARCH=arm make -C tools/testing/selftests/wireguard/qemu -j$(nproc) At the moment, we support aarch64_be, aarch64, arm, armeb, i686, m68k, mips64, mips64el, mips, mipsel, powerpc64le, powerpc, and x86_64. The system supports incremental rebuilding, so it should be very fast to change a single file and then test it out and have immediate feedback. This requires for the right toolchain and qemu to be installed prior. I've had success with those from musl.cc. This is tailored for WireGuard at the moment, though later projects might generalize it for other network testing. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com> Signed-off-by: David S.

UPSTREAM: net: WireGuard secure network tunnel
WireGuard is a layer 3 secure networking tunnel made specifically for the kernel, that aims to be much simpler and easier to audit than IPsec. Extensive documentation and description of the protocol and considerations, along with formal proofs of the cryptography, are available at: * https://www.wireguard.com/ * https://www.wireguard.com/papers/wireguard.pdf This commit implements WireGuard as a simple network device driver, accessible in the usual RTNL way used by virtual network drivers. It makes use of the udp_tunnel APIs, GRO, GSO, NAPI, and the usual set of networking subsystem APIs. It has a somewhat novel multicore queueing system designed for maximum throughput and minimal latency of encryption operations, but it is implemented modestly using workqueues and NAPI. Configuration is done via generic Netlink, and following a review from the Netlink maintainer a year ago, several high profile userspace tools have already implemented the API. This commit also comes with several different tests, both in-kernel tests and out-of-kernel tests based on network namespaces, taking profit of the fact that sockets used by WireGuard intentionally stay in the namespace the WireGuard interface was originally created, exactly like the semantics of userspace tun devices. See wireguard.com/netns/ for pictures and examples. The source code is fairly short, but rather than combining everything into a single file, WireGuard is developed as cleanly separable files, making auditing and comprehension easier. Things are laid out as follows: * noise.[ch], cookie.[ch], messages.h: These implement the bulk of the cryptographic aspects of the protocol, and are mostly data-only in nature, taking in buffers of bytes and spitting out buffers of bytes. They also handle reference counting for their various shared pieces of data, like keys and key lists. * ratelimiter.[ch]: Used as an integral part of cookie.[ch] for ratelimiting certain types of cryptographic operations in accordance with particular WireGuard semantics. * allowedips.[ch], peerlookup.[ch]: The main lookup structures of WireGuard, the former being trie-like with particular semantics, an integral part of the design of the protocol, and the latter just being nice helper functions around the various hashtables we use. * device.[ch]: Implementation of functions for the netdevice and for rtnl, responsible for maintaining the life of a given interface and wiring it up to the rest of WireGuard. * peer.[ch]: Each interface has a list of peers, with helper functions available here for creation, destruction, and reference counting. * socket.[ch]: Implementation of functions related to udp_socket and the general set of kernel socket APIs, for sending and receiving ciphertext UDP packets, and taking care of WireGuard-specific sticky socket routing semantics for the automatic roaming. * netlink.[ch]: Userspace API entry point for configuring WireGuard peers and devices. The API has been implemented by several userspace tools and network management utility, and the WireGuard project distributes the basic wg(8) tool. * queueing.[ch]: Shared function on the rx and tx path for handling the various queues used in the multicore algorithms. * send.c: Handles encrypting outgoing packets in parallel on multiple cores, before sending them in order on a single core, via workqueues and ring buffers. Also handles sending handshake and cookie messages as part of the protocol, in parallel. * receive.c: Handles decrypting incoming packets in parallel on multiple cores, before passing them off in order to be ingested via the rest of the networking subsystem with GRO via the typical NAPI poll function. Also handles receiving handshake and cookie messages as part of the protocol, in parallel. * timers.[ch]: Uses the timer wheel to implement protocol particular event timeouts, and gives a set of very simple event-driven entry point functions for callers. * main.c, version.h: Initialization and deinitialization of the module. * selftest/*.h: Runtime unit tests for some of the most security sensitive functions. * tools/testing/selftests/wireguard/netns.sh: Aforementioned testing script using network namespaces. This commit aims to be as self-contained as possible, implementing WireGuard as a standalone module not needing much special handling or coordination from the network subsystem. I expect for future optimizations to the network stack to positively improve WireGuard, and vice-versa, but for the time being, this exists as intentionally standalone. We introduce a menu option for CONFIG_WIREGUARD, as well as providing a verbose debug log and self-tests via CONFIG_WIREGUARD_DEBUG. Signed-off-by: Jason A.

selftest: use mmap instead of posix_memalign to allocate memory
commit 0db282ba2c12c1515d490d14a1ff696643ab0f1b upstream.
This test passes pointers obtained from anon_allocate_area to the
userfaultfd and mremap APIs. This causes a problem if the system
allocator returns tagged pointers because with the tagged address ABI
the kernel rejects tagged addresses passed to these APIs, which would
end up causing the test to fail. To make this test compatible with such
system allocators, stop using the system allocator to allocate memory in
anon_allocate_area, and instead just use mmap.

selftests/powerpc: Fix "no_handler" EBB selftest
[ Upstream commit 45677c9aebe926192e59475b35a1ff35ff2d4217 ] The "no_handler_test" in ebb selftests attempts to read the PMU registers twice via helper function "dump_ebb_state". First dump is just before closing of event and the second invocation is done after closing of the event. The original intention of second dump_ebb_state was to dump the state of registers at the end of the test when the counters are frozen. But this will be achieved with the first call itself since sample period is set to low value and PMU will be frozen by then. Hence patch removes the dump which was done before closing of the event.

selftests/vm/pkeys: fix alloc_random_pkey() to make it really, really random
[ Upstream commit f36ef407628835a7d7fb3d235b1f1aac7022d9a3 ] Patch series "selftests/vm/pkeys: Bug fixes and a new test". There has been a lot of activity on the x86 front around the XSAVE architecture which is used to context-switch processor state (among other things). In addition, AMD has recently joined the protection keys club by adding processor support for PKU. The AMD implementation helped uncover a kernel bug around the PKRU "init state", which actually applied to Intel's implementation but was just harder to hit. This series adds a test which is expected to help find this class of bug both on AMD and Intel. All the work around pkeys on x86 also uncovered a few bugs in the selftest. This patch (of 4): The "random" pkey allocation code currently does the good old: srand((unsigned int)time(NULL)); *But*, it unfortunately does this on every random pkey allocation. There may be thousands of these a second. time() has a one second resolution. So, each time alloc_random_pkey() is called, the PRNG is *RESET* to time(). This is nasty. Normally, if you do: srand(<ANYTHING>); foo = rand(); bar = rand(); You'll be quite guaranteed that 'foo' and 'bar' are different. But, if you do: srand(1); foo = rand(); srand(1); bar = rand(); You are quite guaranteed that 'foo' and 'bar' are the *SAME*. The recent "fix" effectively forced the test case to use the same "random" pkey for the whole test, unless the test run crossed a second boundary. Only run srand() once at program startup. This explains some very odd and persistent test failures I've been seeing.

selftests/bpf: make 'dubious pointer arithmetic' test useful
commit 31e95b61e172144bb2b626a291db1bdc0769275b upstream.
mostly revert the previous workaround and make
'dubious pointer arithmetic' test useful again.
Use (ptr - ptr) << const instead of ptr << const to generate large scalar.
The rest stays as before commit 2b36047e7889.

selftests/bpf: fix test_align
commit 2b36047e7889b7efee22c11e17f035f721855731 upstream.
since commit 82abbf8d2fc4 the verifier rejects the bit-wise
arithmetic on pointers earlier.
The test 'dubious pointer arithmetic' now has less output to match on.
Adjust it.
