[PATCH 1/1] mm/damon/tests/core-kunit: skip damon_test_nr_accesses_to_accesses_bp() if aggr_interval is zero

by SeongJae Park

The aggregation interval of test purpose damon_attrs for damon_test_nr_accesses_to_accesses_bp() becomes zero on 32 bit architecture, since size of int and long types are same. As a result, damon_nr_accesses_to_accesses_bp() call with the test data triggers divide-by-zero exception. damon_nr_accesses_to_accesses_bp() shouldn't be called with such data, and the non-test code avoids that by checking the case on damon_update_monitoring_results(). Skip the test code in the case, and add an explicit caution of the case on the comment for the test target function.

[PATCH 00/18] random: Include <linux/percpu.h> and resolve circular include dependency

by Uros Bizjak

There were several attempts to resolve circular include dependency after the addition of percpu.h: 1c9df907da83 ("random: fix circular include dependency on arm64 after addition of percpu.h"), c0842fbc1b18 ("random32: move the pseudo-random 32-bit definitions to prandom.h") and finally d9f29deb7fe8 ("prandom: Remove unused include") that completely removes inclusion of <linux/percpu.h>. Due to legacy reasons, <linux/random.h> includes <linux/prandom.h>, but with the commit entry remark: --quote-- A further cleanup step would be to remove this from <linux/random.h> entirely, and make people who use the prandom infrastructure include just the new header file. That's a bit of a churn patch, but grepping for "prandom_" and "next_pseudo_random32" "struct rnd_state" should catch most users. But it turns out that that nice cleanup step is fairly painful, because a _lot_ of code currently seems to depend on the implicit include of <linux/random.h>, which can currently come in a lot of ways, including such fairly core headfers as <linux/net.h>. So the "nice cleanup" part may or may never happen. --/quote-- __percpu tag is currently defined in include/linux/compiler_types.h, so there is no direct need for the inclusion of <linux/percpu.h>. However, in [1] we would like to repurpose __percpu tag as a named address space qualifier, where __percpu macro uses defines from <linux/percpu.h>. This patch series is the "nice cleanup" part, and allows us to finally include <linux/percpu.h> in prandom.h. The whole series was tested by compiling the kernel for x86_64 allconfig and some popular architectures, namely arm64 defconfig, powerpc defconfig and loongarch defconfig.

[PATCH RFC v2 00/10] extensible syscalls: CHECK_FIELDS to allow for easier feature detection

by Aleksa Sarai

This is something that I've been thinking about for a while. We had a discussion at LPC 2020 about this[1] but the proposals suggested there never materialised. In short, it is quite difficult for userspace to detect the feature capability of syscalls at runtime. This is something a lot of programs want to do, but they are forced to create elaborate scenarios to try to figure out if a feature is supported without causing damage to the system. For the vast majority of cases, each individual feature also needs to be tested individually (because syscall results are all-or-nothing), so testing even a single syscall's feature set can easily inflate the startup time of programs. This patchset implements the fairly minimal design I proposed in this talk[2] and in some old LKML threads (though I can't find the exact references ATM). The general flow looks like: 1. Userspace will indicate to the kernel that a syscall should a be no-op by setting the top bit of the extensible struct size argument. We will almost certainly never support exabyte sized structs, so the top bits are free for us to use as makeshift flag bits. This is preferable to using the per-syscall flag field inside the structure because seccomp can easily detect the bit in the flag and allow the probe or forcefully return -EEXTSYS_NOOP. 2. The kernel will then fill the provided structure with every valid bit pattern that the current kernel understands. For flags or other bitflag-like fields, this is the set of valid flags or bits. For pointer fields or fields that take an arbitrary value, the field has every bit set (0xFF... to fill the field) to indicate that any value is valid in the field. 3. The syscall then returns -EEXTSYS_NOOP which is an errno that will only ever be used for this purpose (so userspace can be sure that the request succeeded). On older kernels, the syscall will return a different error (usually -E2BIG or -EFAULT) and userspace can do their old-fashioned checks. 4. Userspace can then check which flags and fields are supported by looking at the fields in the returned structure. Flags are checked by doing an AND with the flags field, and field support can checked by comparing to 0. In principle you could just AND the entire structure if you wanted to do this check generically without caring about the structure contents (this is what libraries might consider doing). Userspace can even find out the internal kernel structure size by passing a PAGE_SIZE buffer and seeing how many bytes are non-zero. As with copy_struct_from_user(), this is designed to be forward- and backwards- compatible. This allows programas to get a one-shot understanding of what features a syscall supports without having to do any elaborate setups or tricks to detect support for destructive features. Flags can simply be ANDed to check if they are in the supported set, and fields can just be checked to see if they are non-zero. This patchset is IMHO the simplest way we can add the ability to introspect the feature set of extensible struct (copy_struct_from_user) syscalls. It doesn't preclude the chance of a more generic mechanism being added later. The intended way of using this interface to get feature information looks something like the following (imagine that openat2 has gained a new field and a new flag in the future): static bool openat2_no_automount_supported; static bool openat2_cwd_fd_supported; int check_openat2_support(void) { int err; struct open_how how = {}; err = openat2(AT_FDCWD, ".", &how, CHECK_FIELDS | sizeof(how)); assert(err < 0); switch (errno) { case EFAULT: case E2BIG: /* Old kernel... */ check_support_the_old_way(); break; case EEXTSYS_NOOP: openat2_no_automount_supported = (how.flags & RESOLVE_NO_AUTOMOUNT); openat2_cwd_fd_supported = (how.cwd_fd != 0); break; } } This series adds CHECK_FIELDS support for the following extensible struct syscalls, as they are quite likely to grow flags in the near future: * openat2 * clone3 * mount_setattr [1]: https://lwn.net/Articles/830666/ [2]: https://youtu.be/ggD-eb3yPVs Signed-off-by: Aleksa Sarai <cyphar(a)cyphar.com> --- Changes in v2: - Add CHECK_FIELDS support to mount_setattr(2). - Fix build failure on architectures with custom errno values. - Rework selftests to use the tools/ uAPI headers rather than custom defining EEXTSYS_NOOP. - Make sure we return -EINVAL and -E2BIG for invalid sizes even if CHECK_FIELDS is set, and add some tests for that. - v1: <https://lore.kernel.org/r/20240902-extensible-structs-check_fields-v1-0-545…> --- Aleksa Sarai (10): uaccess: add copy_struct_to_user helper sched_getattr: port to copy_struct_to_user openat2: explicitly return -E2BIG for (usize > PAGE_SIZE) openat2: add CHECK_FIELDS flag to usize argument selftests: openat2: add 0xFF poisoned data after misaligned struct selftests: openat2: add CHECK_FIELDS selftests clone3: add CHECK_FIELDS flag to usize argument selftests: clone3: add CHECK_FIELDS selftests mount_setattr: add CHECK_FIELDS flag to usize argument selftests: mount_setattr: add CHECK_FIELDS selftest arch/alpha/include/uapi/asm/errno.h | 3 + arch/mips/include/uapi/asm/errno.h | 3 + arch/parisc/include/uapi/asm/errno.h | 3 + arch/sparc/include/uapi/asm/errno.h | 3 + fs/namespace.c | 17 ++ fs/open.c | 18 ++ include/linux/uaccess.h | 98 ++++++++ include/uapi/asm-generic/errno.h | 3 + include/uapi/linux/openat2.h | 2 + kernel/fork.c | 30 ++- kernel/sched/syscalls.c | 42 +--- tools/arch/alpha/include/uapi/asm/errno.h | 3 + tools/arch/mips/include/uapi/asm/errno.h | 3 + tools/arch/parisc/include/uapi/asm/errno.h | 3 + tools/arch/sparc/include/uapi/asm/errno.h | 3 + tools/include/uapi/asm-generic/errno.h | 3 + tools/include/uapi/asm-generic/posix_types.h | 101 ++++++++ tools/testing/selftests/clone3/.gitignore | 1 + tools/testing/selftests/clone3/Makefile | 4 +- .../testing/selftests/clone3/clone3_check_fields.c | 264 +++++++++++++++++++++ tools/testing/selftests/mount_setattr/Makefile | 2 +- .../selftests/mount_setattr/mount_setattr_test.c | 53 ++++- tools/testing/selftests/openat2/Makefile | 2 + tools/testing/selftests/openat2/openat2_test.c | 165 ++++++++++++- 24 files changed, 778 insertions(+), 51 deletions(-) --- base-commit: 431c1646e1f86b949fa3685efc50b660a364c2b6 change-id: 20240803-extensible-structs-check_fields-a47e94cef691 Best regards, -- Aleksa Sarai <cyphar(a)cyphar.com>

[PATCH net-next] selftests: return failure when timestamps can't be parsed

by Jason Xing

From: Jason Xing <kernelxing(a)tencent.com> When I was trying to modify the tx timestamping feature, I found that running "./txtimestamp -4 -C -L 127.0.0.1" didn't reflect the fact properly. In this selftest file, we respectively test three tx generation flags. With the generation and report flag enabled, we expect that the timestamp must be returned to the userspace unless 1) generating the timestamp fails, 2) reporting the timestamp fails. So we should test if the timestamps can be read and parsed succuessfuly in txtimestamp.c, or else there is a bug in the kernel. After adding the check so that running ./txtimestamp will reflect the result correctly like this if there is an error in kernel: protocol: TCP payload: 10 server port: 9000 family: INET test SND USR: 1725458477 s 667997 us (seq=0, len=0) Failed to parse timestamps USR: 1725458477 s 718128 us (seq=0, len=0) Failed to parse timestamps USR: 1725458477 s 768273 us (seq=0, len=0) Failed to parse timestamps USR: 1725458477 s 818416 us (seq=0, len=0) Failed to parse timestamps ...

[PATCH net-next RFC] selftests/net: integrate packetdrill with ksft

by Willem de Bruijn

From: Willem de Bruijn <willemb(a)google.com> Lay the groundwork to import into kselftests the over 150 packetdrill TCP/IP conformance tests on github.com/google/packetdrill. Florian recently added support for packetdrill tests in nf_conntrack, in commit a8a388c2aae49 ("selftests: netfilter: add packetdrill based conntrack tests"). This patch takes a slightly different implementation and reuses the ksft python library for its KTAP, ksft, NetNS and other such tooling. It also anticipates the large number of testcases, by creating a separate kselftest for each feature (directory). It does this by copying the template script packetdrill_ksft.py for each directory, and putting those in TEST_CUSTOM_PROGS so that kselftests runs each. To demonstrate the code with minimal patch size, initially import only two features/directories from github. One with a single script, and one with two. This was the only reason to pick tcp/inq and tcp/md5. Any future imports of packetdrill tests should require no additional coding. Just add the tcp/$FEATURE directory with *.pkt files. Implementation notes: - restore alphabetical order when adding the new directory to tools/testing/selftests/Makefile - copied *.pkt files and support verbatim from the github project, except for - update common/defaults.sh path (there are two paths on github) - add SPDX headers - remove one author statement - Acknowledgment: drop an e (checkpatch) Tested: make -C tools/testing/selftests/ \ TARGETS=net/packetdrill \ install INSTALL_PATH=$KSFT_INSTALL_PATH # in virtme-ng sudo ./run_kselftest.sh -c net/packetdrill sudo ./run_kselftest.sh -t net/packetdrill:tcp_inq.py Result: kselftest: Running tests in net/packetdrill TAP version 13 1..2 # timeout set to 45 # selftests: net/packetdrill: tcp_inq.py # KTAP version 1 # 1..4 # ok 1 tcp_inq.client-v4 # ok 2 tcp_inq.client-v6 # ok 3 tcp_inq.server-v4 # ok 4 tcp_inq.server-v6 # # Totals: pass:4 fail:0 xfail:0 xpass:0 skip:0 error:0 ok 1 selftests: net/packetdrill: tcp_inq.py # timeout set to 45 # selftests: net/packetdrill: tcp_md5.py # KTAP version 1 # 1..2 # ok 1 tcp_md5.md5-only-on-client-ack-v4 # ok 2 tcp_md5.md5-only-on-client-ack-v6 # # Totals: pass:2 fail:0 xfail:0 xpass:0 skip:0 error:0 ok 2 selftests: net/packetdrill: tcp_md5.py Signed-off-by: Willem de Bruijn <willemb(a)google.com> --- RFC points for discussion ksft: the choice for this python framework introduces a dependency on the YNL scripts, and some non-obvious code: - to include the net/lib dep in tools/testing/selftests/Makefile - a boilerplate lib/py/__init__.py that each user of ksft will need It seems preferable to me to use ksft.py over reinventing the wheel, e.g., to print KTAP output. But perhaps we can make it more obvious for future ksft users, and make the dependency on YNL optional. kselftest-per-directory: copying packetdrill_ksft.py to create a separate script per dir is a bit of a hack. A single script is much simpler, optionally with nested KTAP (not supported yet by ksft). But, I'm afraid that running time without intermediate output will be very long when we integrate all packetdrill scripts. nf_conntrack: we can dedup the common.sh. *pkt files: which of the 150+ scripts on github are candidates for kselftests, all or a subset? To avoid change detector tests. And what is the best way to eventually send up to 150 files, 7K LoC. --- tools/testing/selftests/Makefile | 7 +- .../selftests/net/packetdrill/.gitignore | 1 + .../selftests/net/packetdrill/Makefile | 28 ++++++ .../net/packetdrill/lib/py/__init__.py | 15 ++++ .../net/packetdrill/packetdrill_ksft.py | 90 +++++++++++++++++++ .../net/packetdrill/tcp/common/defaults.sh | 63 +++++++++++++ .../net/packetdrill/tcp/common/set_sysctls.py | 38 ++++++++ .../net/packetdrill/tcp/inq/client.pkt | 51 +++++++++++ .../net/packetdrill/tcp/inq/server.pkt | 51 +++++++++++ .../tcp/md5/md5-only-on-client-ack.pkt | 28 ++++++ 10 files changed, 369 insertions(+), 3 deletions(-) create mode 100644 tools/testing/selftests/net/packetdrill/.gitignore create mode 100644 tools/testing/selftests/net/packetdrill/Makefile create mode 100644 tools/testing/selftests/net/packetdrill/lib/py/__init__.py create mode 100755 tools/testing/selftests/net/packetdrill/packetdrill_ksft.py create mode 100755 tools/testing/selftests/net/packetdrill/tcp/common/defaults.sh create mode 100755 tools/testing/selftests/net/packetdrill/tcp/common/set_sysctls.py create mode 100644 tools/testing/selftests/net/packetdrill/tcp/inq/client.pkt create mode 100644 tools/testing/selftests/net/packetdrill/tcp/inq/server.pkt create mode 100644 tools/testing/selftests/net/packetdrill/tcp/md5/md5-only-on-client-ack.pkt diff --git a/tools/testing/selftests/Makefile b/tools/testing/selftests/Makefile index a5f1c0c27dff9..f03d6fee7ac54 100644 --- a/tools/testing/selftests/Makefile +++ b/tools/testing/selftests/Makefile @@ -65,10 +65,11 @@ TARGETS += net/af_unix TARGETS += net/forwarding TARGETS += net/hsr TARGETS += net/mptcp -TARGETS += net/openvswitch -TARGETS += net/tcp_ao TARGETS += net/netfilter +TARGETS += net/openvswitch +TARGETS += net/packetdrill TARGETS += net/rds +TARGETS += net/tcp_ao TARGETS += nsfs TARGETS += perf_events TARGETS += pidfd @@ -122,7 +123,7 @@ TARGETS_HOTPLUG = cpu-hotplug TARGETS_HOTPLUG += memory-hotplug #
