[PATCH v7 linux-kselftest-test 0/6] kunit: support building core/tests as modules

by Alan Maguire

The current kunit execution model is to provide base kunit functionality and tests built-in to the kernel. The aim of this series is to allow building kunit itself and tests as modules. This in turn allows a simple form of selective execution; load the module you wish to test. In doing so, kunit itself (if also built as a module) will be loaded as an implicit dependency. Because this requires a core API modification - if a module delivers multiple suites, they must be declared with the kunit_test_suites() macro - we're proposing this patch set as a candidate to be applied to the test tree before too many kunit consumers appear. We attempt to deal with existing consumers in patch 3. Changes since v6: - reintroduce kunit_test_suite() definition to handle users in other trees not yet converted to using kunit_test_suites() (kbuild error when applying patches to ext4/dev tree) - modify drivers/base/power/qos-test.c to use kunit_test_suites() to register suite. We do not convert it to support module build now as the suite uses a few unexported function; see patch 3 for details. Changes since v5: - fixed fs/ext4/Makefile to remove unneeded conditional compilation (Iurii, patch 3) - added Reviewed-by, Acked-by to patches 3, 4, 5 and 6 Changes since v4: - fixed signoff chain to use Co-developed-by: prior to Knut's signoff (Stephen, all patches) - added Reviewed-by, Tested-by for patches 1, 2, 4 and 6 - updated comment describing try-catch-impl.h (Stephen, patch 2) - fixed MODULE_LICENSEs to be GPL v2 (Stephen, patches 3, 5) - added __init to kunit_init() (Stephen, patch 5) Changes since v3: - removed symbol lookup patch for separate submission later - removed use of sysctl_hung_task_timeout_seconds (patch 4, as discussed with Brendan and Stephen) - disabled build of string-stream-test when CONFIG_KUNIT_TEST=m; this is to avoid having to deal with symbol lookup issues - changed string-stream-impl.h back to string-stream.h (Brendan) - added module build support to new list, ext4 tests Changes since v2: - moved string-stream.h header to lib/kunit/string-stream-impl.h (Brendan) (patch 1) - split out non-exported interfaces in try-catch-impl.h (Brendan) (patch 2) - added kunit_find_symbol() and KUNIT_INIT_SYMBOL to lookup non-exported symbols (patches 3, 4) - removed #ifdef MODULE around module licenses (Randy, Brendan, Andy) (patch 4) - replaced kunit_test_suite() with kunit_test_suites() rather than supporting both (Brendan) (patch 4) - lookup sysctl_hung_task_timeout_secs as kunit may be built as a module and the symbol may not be available (patch 5) Alan Maguire (6): kunit: move string-stream.h to lib/kunit kunit: hide unexported try-catch interface in try-catch-impl.h kunit: allow kunit tests to be loaded as a module kunit: remove timeout dependence on sysctl_hung_task_timeout_seconds kunit: allow kunit to be loaded as a module kunit: update documentation to describe module-based build Documentation/dev-tools/kunit/faq.rst | 3 +- Documentation/dev-tools/kunit/index.rst | 3 ++ Documentation/dev-tools/kunit/usage.rst | 16 ++++++++++ drivers/base/power/qos-test.c | 2 +- fs/ext4/Kconfig | 2 +- fs/ext4/Makefile | 3 +- fs/ext4/inode-test.c | 4 ++- include/kunit/assert.h | 3 +- include/kunit/test.h | 37 ++++++++++++++++------ include/kunit/try-catch.h | 10 ------ kernel/sysctl-test.c | 4 ++- lib/Kconfig.debug | 4 +-- lib/kunit/Kconfig | 6 ++-- lib/kunit/Makefile | 14 +++++--- lib/kunit/assert.c | 10 ++++++ lib/kunit/{example-test.c => kunit-example-test.c} | 4 ++- lib/kunit/{test-test.c => kunit-test.c} | 7 ++-- lib/kunit/string-stream-test.c | 5 +-- lib/kunit/string-stream.c | 3 +- {include => lib}/kunit/string-stream.h | 0 lib/kunit/test.c | 25 ++++++++++++++- lib/kunit/try-catch-impl.h | 27 ++++++++++++++++ lib/kunit/try-catch.c | 37 +++++----------------- lib/list-test.c | 4 ++- 24 files changed, 160 insertions(+), 73 deletions(-) rename lib/kunit/{example-test.c => kunit-example-test.c} (97%) rename lib/kunit/{test-test.c => kunit-test.c} (98%) rename {include => lib}/kunit/string-stream.h (100%) create mode 100644 lib/kunit/try-catch-impl.h -- 1.8.3.1

I believe this is not correct: the code does not really access memory beyond the end of the source string. (Recent) gcc just thinks so, because "__src+__n" is used as a parameter to the routine. > 2nd is it needs big fixup for it, and maintenance __asm__ > code is difficult.

That will definitely fix the issue, as we assume the generic implementation is correct ;-) Now, I've just tried, naively, to enable CONFIG_STRING_SELFTEST=y in my rts7751r2d build (without your patch), and boot it in qemu: String selftests succeeded Woops, turns out lib/test_string.c does not have any testcases for strncpy()... So adding test code for the corner cases may be a valuable contribution. Thanks!

[PATCH 3/3] selftests/cgroup: add tests for cloning into cgroups

by Christian Brauner

Expand the cgroup test-suite to include tests for CLONE_INTO_CGROUP. This adds the following tests: - CLONE_INTO_CGROUP manages to clone a process directly into a correctly delegated cgroup - CLONE_INTO_CGROUP fails to clone a process into a cgroup that has been removed after we've opened an fd to it - CLONE_INTO_CGROUP fails to clone a process into an invalid domain cgroup - CLONE_INTO_CGROUP adheres to the no internal process constraint - CLONE_INTO_CGROUP works with the freezer feature Cc: Roman Gushchin <guro(a)fb.com> Cc: Tejun Heo <tj(a)kernel.org> Cc: Shuah Khan <shuah(a)kernel.org> Cc: cgroups(a)vger.kernel.org Cc: linux-kselftest(a)vger.kernel.org Signed-off-by: Christian Brauner <christian.brauner(a)ubuntu.com> --- tools/testing/selftests/cgroup/Makefile | 6 +- tools/testing/selftests/cgroup/cgroup_util.c | 126 ++++++++++++++++++ tools/testing/selftests/cgroup/cgroup_util.h | 4 + tools/testing/selftests/cgroup/test_core.c | 67 ++++++++++ .../selftests/clone3/clone3_selftests.h | 19 ++- 5 files changed, 217 insertions(+), 5 deletions(-) diff --git a/tools/testing/selftests/cgroup/Makefile b/tools/testing/selftests/cgroup/Makefile index 66aafe1f5746..967f268fde74 100644 --- a/tools/testing/selftests/cgroup/Makefile +++ b/tools/testing/selftests/cgroup/Makefile @@ -11,6 +11,6 @@ TEST_GEN_PROGS += test_freezer include ../lib.mk -$(OUTPUT)/test_memcontrol: cgroup_util.c -$(OUTPUT)/test_core: cgroup_util.c -$(OUTPUT)/test_freezer: cgroup_util.c +$(OUTPUT)/test_memcontrol: cgroup_util.c ../clone3/clone3_selftests.h +$(OUTPUT)/test_core: cgroup_util.c ../clone3/clone3_selftests.h +$(OUTPUT)/test_freezer: cgroup_util.c ../clone3/clone3_selftests.h diff --git a/tools/testing/selftests/cgroup/cgroup_util.c b/tools/testing/selftests/cgroup/cgroup_util.c index 8f7131dcf1ff..8a637ca7d73a 100644 --- a/tools/testing/selftests/cgroup/cgroup_util.c +++ b/tools/testing/selftests/cgroup/cgroup_util.c @@ -15,6 +15,7 @@ #include <unistd.h> #include "cgroup_util.h" +#include "../clone3/clone3_selftests.h" static ssize_t read_text(const char *path, char *buf, size_t max_len) { @@ -331,12 +332,112 @@ int cg_run(const char *cgroup, } } +pid_t clone_into_cgroup(int cgroup_fd) +{ +#ifdef CLONE_ARGS_SIZE_VER2 + pid_t pid; + + struct clone_args args = { + .flags = CLONE_INTO_CGROUP, + .exit_signal = SIGCHLD, + .cgroup = cgroup_fd, + }; + + pid = sys_clone3(&args, sizeof(struct clone_args)); + /* + * Verify that this is a genuine test failure: + * ENOSYS -> clone3() not available + * E2BIG -> CLONE_INTO_CGROUP not available + */ + if (pid < 0 && (errno == ENOSYS || errno == E2BIG)) + goto pretend_enosys; + + return pid; + +pretend_enosys: +#endif + errno = ENOSYS; + return -ENOSYS; +} + +int clone_reap(pid_t pid, int options) +{ + int ret; + siginfo_t info = { + .si_signo = 0, + }; + +again: + ret = waitid(P_PID, pid, &info, options | __WALL | __WNOTHREAD); + if (ret < 0) { + if (errno == EINTR) + goto again; + return -1; + } + + if (options & WEXITED) { + if (WIFEXITED(info.si_status)) + return WEXITSTATUS(info.si_status); + } + + if (options & WSTOPPED) { + if (WIFSTOPPED(info.si_status)) + return WSTOPSIG(info.si_status); + } + + if (options & WCONTINUED) { + if (WIFCONTINUED(info.si_status)) + return 0; + } + + return -1; +} + +int dirfd_open_opath(const char *dir) +{ + return open(dir, O_DIRECTORY | O_CLOEXEC | O_NOFOLLOW | O_PATH); +} + +#define close_prot_errno(fd) \ + if (fd >= 0) { \ + int _e_ = errno; \ + close(fd); \ + errno = _e_; \ + } + +static int clone_into_cgroup_run_nowait(const char *cgroup, + int (*fn)(const char *cgroup, void *arg), + void *arg) +{ + int cgroup_fd; + pid_t pid; + + cgroup_fd = dirfd_open_opath(cgroup); + if (cgroup_fd < 0) + return -1; + + pid = clone_into_cgroup(cgroup_fd); + close_prot_errno(cgroup_fd); + if (pid == 0) + exit(fn(cgroup, arg)); + + return pid; +} + int cg_run_nowait(const char *cgroup, int (*fn)(const char *cgroup, void *arg), void *arg) { int pid; + pid = clone_into_cgroup_run_nowait(cgroup, fn, arg); + if (pid > 0) + return pid; + + /* Genuine test failure. */ + if (pid < 0 && errno != ENOSYS) + return -1; + pid = fork(); if (pid == 0) { char buf[64]; @@ -450,3 +551,28 @@ int proc_read_strstr(int pid, bool thread, const char *item, const char *needle) return strstr(buf, needle) ? 0 : -1; } + +int clone_into_cgroup_run_wait(const char *cgroup) +{ + int cgroup_fd; + pid_t pid; + + cgroup_fd = dirfd_open_opath(cgroup); + if (cgroup_fd < 0) + return -1; + + pid = clone_into_cgroup(cgroup_fd); + close_prot_errno(cgroup_fd); + if (pid < 0) + return -1; + + if (pid == 0) + exit(EXIT_SUCCESS); + + /* + * We don't care whether this fails.

[PATCH] openat2: switch to __attribute__((packed)) for open_how

by Aleksa Sarai

The design of the original open_how struct layout was such that it ensured that there would be no un-labelled (and thus potentially non-zero) padding to avoid issues with struct expansion, as well as providing a uniform representation on all architectures (to avoid complications with OPEN_HOW_SIZE versioning). However, there were a few other desirable features which were not fulfilled by the previous struct layout: * Adding new features (other than new flags) should always result in the struct getting larger. However, by including a padding field, it was possible for new fields to be added without expanding the structure. This would somewhat complicate version-number based checking of feature support. * A non-zero bit in __padding yielded -EINVAL when it should arguably have been -E2BIG (because the padding bits are effectively yet-to-be-used fields). However, the semantics are not entirely clear because userspace may expect -E2BIG to only signify that the structure is too big. It's much simpler to just provide the guarantee that new fields will always result in a struct size increase, and -E2BIG indicates you're using a field that's too recent for an older kernel. * While the alignment for u64s was manually backed by extra padding fields, some languages (such as Rust) do not currently support enforcing alignment of struct field members. * The padding wasted space needlessly, and would very likely not be used up entirely by future extensions for a long time (because it couldn't fit a u64). While none of these outstanding issues are deal-breakers, we can iron out these warts before openat2(2) lands in Linus's tree. Instead of using alignment and padding, we simply pack the structure with __attribute__((packed)). Rust supports #[repr(packed)] and it removes all of the issues with having explicit padding.

livepatch test configures the system and debug environment to run tests. Some of these actions fail without root access and test dumps several permission denied messages before it exits.

[PATCH v9 00/25] mm/gup: track dma-pinned pages: FOLL_PIN

by John Hubbard

Hi, This implements an API naming change (put_user_page*() --> unpin_user_page*()), and also implements tracking of FOLL_PIN pages. It extends that tracking to a few select subsystems. More subsystems will be added in follow up work. Christoph Hellwig, a point of interest: a) I've moved the bulk of the code out of the inline functions, as requested, for the devmap changes (patch 4: "mm: devmap: refactor 1-based refcounting for ZONE_DEVICE pages"). Changes since v8: * Merged the "mm/gup: pass flags arg to __gup_device_* functions" patch into the "mm/gup: track FOLL_PIN pages" patch, as requested by Christoph and Jan. * Changed void grab_page() to bool try_grab_page(), and handled errors at the call sites. (From Jan's review comments.) try_grab_page() attempts to avoid page refcount overflows, even when counting up with GUP_PIN_COUNTING_BIAS increments. * Fixed a bug that I'd introduced, when changing a BUG() to a WARN(). * Added Jan's reviewed-by tag to the " mm/gup: allow FOLL_FORCE for get_user_pages_fast()" patch. * Documentation: pin_user_pages.rst: fixed an incorrect gup_benchmark invocation, left over from the pin_longterm days, spotted while preparing this version. * Rebased onto today's linux.git (-rc1), and re-tested. Changes since v7: * Rebased onto Linux 5.5-rc1 * Reworked the grab_page() and try_grab_compound_head(), for API consistency and less diffs (thanks to Jan Kara's reviews). * Added Leon Romanovsky's reviewed-by tags for two of the IB-related patches. * patch 4 refactoring changes, as mentioned above. There is a git repo and branch, for convenience: git@github.com:johnhubbard/linux.git pin_user_pages_tracking_v8 For the remaining list of "changes since version N", those are all in v7, which is here: https://lore.kernel.org/r/20191121071354.456618-1-jhubbard@nvidia.com ============================================================ Overview: This is a prerequisite to solving the problem of proper interactions between file-backed pages, and [R]DMA activities, as discussed in [1], [2], [3], and in a remarkable number of email threads since about 2017. :) A new internal gup flag, FOLL_PIN is introduced, and thoroughly documented in the last patch's Documentation/vm/pin_user_pages.rst. I believe that this will provide a good starting point for doing the layout lease work that Ira Weiny has been working on. That's because these new wrapper functions provide a clean, constrained, systematically named set of functionality that, again, is required in order to even know if a page is "dma-pinned". In contrast to earlier approaches, the page tracking can be incrementally applied to the kernel call sites that, until now, have been simply calling get_user_pages() ("gup"). In other words, opt-in by changing from this: get_user_pages() (sets FOLL_GET) put_page() to this: pin_user_pages() (sets FOLL_PIN) unpin_user_page() ============================================================ Testing: * I've done some overall kernel testing (LTP, and a few other goodies), and some directed testing to exercise some of the changes. And as you can see, gup_benchmark is enhanced to exercise this. Basically, I've been able to runtime test the core get_user_pages() and pin_user_pages() and related routines, but not so much on several of the call sites--but those are generally just a couple of lines changed, each. Not much of the kernel is actually using this, which on one hand reduces risk quite a lot. But on the other hand, testing coverage is low. So I'd love it if, in particular, the Infiniband and PowerPC folks could do a smoke test of this series for me. Runtime testing for the call sites so far is pretty light: * io_uring: Some directed tests from liburing exercise this, and they pass. * process_vm_access.c: A small directed test passes. * gup_benchmark: the enhanced version hits the new gup.c code, and passes. * infiniband: ran "ib_write_bw", which exercises the umem.c changes, but not the other changes. * VFIO: compiles (I'm vowing to set up a run time test soon, but it's not ready just yet) * powerpc: it compiles... * drm/via: compiles... * goldfish: compiles... * net/xdp: compiles... * media/v4l2: compiles...

Changes since v9: Fixes resulting from Jan Kara's and Jonathan Corbet's reviews: * Removed reviewed-by tags from the "mm/gup: track FOLL_PIN pages" (those were improperly inherited from the much smaller refactoring patch that was merged into it). * Made try_grab_compound_head() and try_grab_page() behavior similar in their behavior with flags, in order to avoid "gotchas" later. * follow_trans_huge_pmd(): moved the try_grab_page() to earlier in the routine, in order to avoid having to undo mlock_vma_page(). * follow_hugetlb_page(): removed a refcount overflow check that is now extraneous (and weaker than what try_grab_page() provides a few lines further down). * Fixed up two Documentation flaws, pointed out by Jonathan Corbet's review. Changes since v8: * Merged the "mm/gup: pass flags arg to __gup_device_* functions" patch into the "mm/gup: track FOLL_PIN pages" patch, as requested by Christoph and Jan. * Changed void grab_page() to bool try_grab_page(), and handled errors at the call sites.

[PATCH 0/9] Create a userfaultfd demand paging test

by Ben Gardon

When handling page faults for many vCPUs during demand paging, KVM's MMU lock becomes highly contended. This series creates a test with a naive userfaultfd based demand paging implementation to demonstrate that contention. This test serves both as a functional test of userfaultfd and a microbenchmark of demand paging performance with a variable number of vCPUs and memory per vCPU. The test creates N userfaultfd threads, N vCPUs, and a region of memory with M pages per vCPU. The N userfaultfd polling threads are each set up to serve faults on a region of memory corresponding to one of the vCPUs. Each of the vCPUs is then started, and touches each page of its disjoint memory region, sequentially. In response to faults, the userfaultfd threads copy a static buffer into the guest's memory. This creates a worst case for MMU lock contention as we have removed most of the contention between the userfaultfd threads and there is no time required to fetch the contents of guest memory. This test was run successfully on Intel Haswell, Broadwell, and Cascadelake hosts with a variety of vCPU counts and memory sizes. This test was adapted from the dirty_log_test. The series can also be viewed in Gerrit here: https://linux-review.googlesource.com/c/virt/kvm/kvm/+/1464 (Thanks to Dmitry Vyukov <dvyukov(a)google.com> for setting up the Gerrit instance) Ben Gardon (9): KVM: selftests: Create a demand paging test KVM: selftests: Add demand paging content to the demand paging test KVM: selftests: Add memory size parameter to the demand paging test KVM: selftests: Pass args to vCPU instead of using globals KVM: selftests: Support multiple vCPUs in demand paging test KVM: selftests: Time guest demand paging KVM: selftests: Add parameter to _vm_create for memslot 0 base paddr KVM: selftests: Support large VMs in demand paging test Add static flag tools/testing/selftests/kvm/.gitignore | 1 + tools/testing/selftests/kvm/Makefile | 4 +- .../selftests/kvm/demand_paging_test.c | 610 ++++++++++++++++++ tools/testing/selftests/kvm/dirty_log_test.c | 2 +- .../testing/selftests/kvm/include/kvm_util.h | 3 +- tools/testing/selftests/kvm/lib/kvm_util.c | 7 +- 6 files changed, 621 insertions(+), 6 deletions(-) create mode 100644 tools/testing/selftests/kvm/demand_paging_test.c -- 2.23.0.444.g18eeb5a265-goog

[PATCH] selftests: livepatch: Fix it to do root uid check and skip

by Shuah Khan

livepatch test configures the system and debug environment to run tests. Some of these actions fail without root access and test dumps several permission denied messages before it exits.

[PATCH] selftests: net: tls: remove recv_rcvbuf test

by Thadeu Lima de Souza Cascardo

This test only works when [1] is applied, which was rejected. Basically, the errors are reported and cleared. In this particular case of tls sockets, following reads will block. The test case was originally submitted with the rejected patch, but, then, was included as part of a different patchset, possibly by mistake.

Hi, This implements an API naming change (put_user_page*() --> unpin_user_page*()), and also implements tracking of FOLL_PIN pages. It extends that tracking to a few select subsystems. More subsystems will be added in follow up work. Christoph Hellwig, a couple of points of interest: a) I've moved the bulk of the code out of the inline functions, as requested, for the devmap changes (patch 4: "mm: devmap: refactor 1-based refcounting for ZONE_DEVICE pages"). b) Contrary to my earlier response to your review, I have not actually merged patch 23 ("mm/gup: pass flags arg to __gup_device_* functions") into patch 24 ("mm/gup: track FOLL_PIN pages"). This is because I suspect that it's better to avoid making patch 24 any larger and worse to review than it already is. But if you feel strongly about it, I'll combine them anyway. Changes since v7: * Rebased onto Linux 5.5-rc1 * Reworked the grab_page() and try_grab_compound_head(), for API consistency and less diffs (thanks to Jan Kara's reviews). * Added Leon Romanovsky's reviewed-by tags for two of the IB-related patches. * patch 4 refactoring changes, as mentioned above. There is a git repo and branch, for convenience: git@github.com:johnhubbard/linux.git pin_user_pages_tracking_v8 For the remaining list of "changes since version N", those are all in v7, which is here: https://lore.kernel.org/r/20191121071354.456618-1-jhubbard@nvidia.com ============================================================ Overview: This is a prerequisite to solving the problem of proper interactions between file-backed pages, and [R]DMA activities, as discussed in [1], [2], [3], and in a remarkable number of email threads since about 2017. :) A new internal gup flag, FOLL_PIN is introduced, and thoroughly documented in the last patch's Documentation/vm/pin_user_pages.rst. I believe that this will provide a good starting point for doing the layout lease work that Ira Weiny has been working on. That's because these new wrapper functions provide a clean, constrained, systematically named set of functionality that, again, is required in order to even know if a page is "dma-pinned". In contrast to earlier approaches, the page tracking can be incrementally applied to the kernel call sites that, until now, have been simply calling get_user_pages() ("gup"). In other words, opt-in by changing from this: get_user_pages() (sets FOLL_GET) put_page() to this: pin_user_pages() (sets FOLL_PIN) unpin_user_page() ============================================================ Testing: * I've done some overall kernel testing (LTP, and a few other goodies), and some directed testing to exercise some of the changes. And as you can see, gup_benchmark is enhanced to exercise this. Basically, I've been able to runtime test the core get_user_pages() and pin_user_pages() and related routines, but not so much on several of the call sites--but those are generally just a couple of lines changed, each. Not much of the kernel is actually using this, which on one hand reduces risk quite a lot. But on the other hand, testing coverage is low. So I'd love it if, in particular, the Infiniband and PowerPC folks could do a smoke test of this series for me. Runtime testing for the call sites so far is pretty light: * io_uring: Some directed tests from liburing exercise this, and they pass. * process_vm_access.c: A small directed test passes. * gup_benchmark: the enhanced version hits the new gup.c code, and passes. * infiniband: ran "ib_write_bw", which exercises the umem.c changes, but not the other changes. * VFIO: compiles (I'm vowing to set up a run time test soon, but it's not ready just yet) * powerpc: it compiles... * drm/via: compiles... * goldfish: compiles... * net/xdp: compiles... * media/v4l2: compiles...

[PATCH AUTOSEL 5.4 327/350] libbpf: Fix call relocation offset calculation bug

by Sasha Levin

From: Andrii Nakryiko <andriin(a)fb.com> [ Upstream commit a0d7da26ce86a25e97ae191cb90574ada6daea98 ] When relocating subprogram call, libbpf doesn't take into account relo->text_off, which comes from symbol's value. This generally works fine for subprograms implemented as static functions, but breaks for global functions. Taking a simplified test_pkt_access.c as an example: __attribute__ ((noinline)) static int test_pkt_access_subprog1(volatile struct __sk_buff *skb) { return skb->len * 2; } __attribute__ ((noinline)) static int test_pkt_access_subprog2(int val, volatile struct __sk_buff *skb) { return skb->len + val; } SEC("classifier/test_pkt_access") int test_pkt_access(struct __sk_buff *skb) { if (test_pkt_access_subprog1(skb) != skb->len * 2) return TC_ACT_SHOT; if (test_pkt_access_subprog2(2, skb) != skb->len + 2) return TC_ACT_SHOT; return TC_ACT_UNSPEC; } When compiled, we get two relocations, pointing to '.text' symbol. .text has st_value set to 0 (it points to the beginning of .text section): 0000000000000008 000000050000000a R_BPF_64_32 0000000000000000 .text 0000000000000040 000000050000000a R_BPF_64_32 0000000000000000 .text test_pkt_access_subprog1 and test_pkt_access_subprog2 offsets (targets of two calls) are encoded within call instruction's imm32 part as -1 and 2, respectively: 0000000000000000 test_pkt_access_subprog1: 0: 61 10 00 00 00 00 00 00 r0 = *(u32 *)(r1 + 0) 1: 64 00 00 00 01 00 00 00 w0 <<= 1 2: 95 00 00 00 00 00 00 00 exit 0000000000000018 test_pkt_access_subprog2: 3: 61 10 00 00 00 00 00 00 r0 = *(u32 *)(r1 + 0) 4: 04 00 00 00 02 00 00 00 w0 += 2 5: 95 00 00 00 00 00 00 00 exit 0000000000000000 test_pkt_access: 0: bf 16 00 00 00 00 00 00 r6 = r1 ===> 1: 85 10 00 00 ff ff ff ff call -1 2: bc 01 00 00 00 00 00 00 w1 = w0 3: b4 00 00 00 02 00 00 00 w0 = 2 4: 61 62 00 00 00 00 00 00 r2 = *(u32 *)(r6 + 0) 5: 64 02 00 00 01 00 00 00 w2 <<= 1 6: 5e 21 08 00 00 00 00 00 if w1 != w2 goto +8 <LBB0_3> 7: bf 61 00 00 00 00 00 00 r1 = r6 ===> 8: 85 10 00 00 02 00 00 00 call 2 9: bc 01 00 00 00 00 00 00 w1 = w0 10: 61 62 00 00 00 00 00 00 r2 = *(u32 *)(r6 + 0) 11: 04 02 00 00 02 00 00 00 w2 += 2 12: b4 00 00 00 ff ff ff ff w0 = -1 13: 1e 21 01 00 00 00 00 00 if w1 == w2 goto +1 <LBB0_3> 14: b4 00 00 00 02 00 00 00 w0 = 2 0000000000000078 LBB0_3: 15: 95 00 00 00 00 00 00 00 exit Now, if we compile example with global functions, the setup changes.

All that is shifted by number of instructions in main program, given all sub-programs are copied over after main program. Convert few selftests relying on bpf-to-bpf calls to use global functions instead of static ones.

From: Yonghong Song <yhs(a)fb.com> [ Upstream commit 2ea2612b987ad703235c92be21d4e98ee9c2c67c ] Currently, with latest llvm trunk, selftest test_progs failed obj file test_seg6_loop.o with the following error in verifier: infinite loop detected at insn 76 The byte code sequence looks like below, and noted that alu32 has been turned off by default for better generated codes in general: 48: w3 = 100 49: *(u32 *)(r10 - 68) = r3 ... ; if (tlv.type == SR6_TLV_PADDING) { 76: if w3 == 5 goto -18 <LBB0_19> ... 85: r1 = *(u32 *)(r10 - 68) ; for (int i = 0; i < 100; i++) { 86: w1 += -1 87: if w1 == 0 goto +5 <LBB0_20> 88: *(u32 *)(r10 - 68) = r1 The main reason for verification failure is due to partial spills at r10 - 68 for induction variable "i". Current verifier only handles spills with 8-byte values. The above 4-byte value spill to stack is treated to STACK_MISC and its content is not saved. For the above example: w3 = 100 R3_w=inv100 fp-64_w=inv1086626730498 *(u32 *)(r10 - 68) = r3 R3_w=inv100 fp-64_w=inv1086626730498 ... r1 = *(u32 *)(r10 - 68) R1_w=inv(id=0,umax_value=4294967295,var_off=(0x0; 0xffffffff)) fp-64=inv1086626730498 To resolve this issue, verifier needs to be extended to track sub-registers in spilling, or llvm needs to enhanced to prevent sub-register spilling in register allocation phase. The former will increase verifier complexity and the latter will need some llvm "hacking". Let us workaround this issue by declaring the induction variable as "long" type so spilling will happen at non sub-register level. We can revisit this later if sub-register spilling causes similar or other verification issues.

[PATCH AUTOSEL 5.4 306/350] selftests, bpf: Fix test_tc_tunnel hanging

by Sasha Levin

From: Jiri Benc <jbenc(a)redhat.com> [ Upstream commit 3b054b7133b4ad93671c82e8d6185258e3f1a7a5 ] When run_kselftests.sh is run, it hangs after test_tc_tunnel.sh. The reason is test_tc_tunnel.sh ensures the server ('nc -l') is run all the time, starting it again every time it is expected to terminate. The exception is the final client_connect: the server is not started anymore, which ensures no process is kept running after the test is finished. For a sit test, though, the script is terminated prematurely without the final client_connect and the 'nc' process keeps running. This in turn causes the run_one function in kselftest/runner.sh to hang forever, waiting for the runaway process to finish. Ensure a remaining server is terminated on cleanup.

[PATCH AUTOSEL 5.4 267/350] bpf, testing: Workaround a verifier failure for test_progs

by Sasha Levin

From: Yonghong Song <yhs(a)fb.com> [ Upstream commit b7a0d65d80a0c5034b366392624397a0915b7556 ] With latest llvm compiler, running test_progs will have the following verifier failure for test_sysctl_loop1.o: libbpf: load bpf program failed: Permission denied libbpf: -- BEGIN DUMP LOG --- libbpf: invalid indirect read from stack var_off (0x0; 0xff)+196 size 7 ... libbpf: -- END LOG -- libbpf: failed to load program 'cgroup/sysctl' libbpf: failed to load object 'test_sysctl_loop1.o' The related bytecode looks as below: 0000000000000308 LBB0_8: 97: r4 = r10 98: r4 += -288 99: r4 += r7 100: w8 &= 255 101: r1 = r10 102: r1 += -488 103: r1 += r8 104: r2 = 7 105: r3 = 0 106: call 106 107: w1 = w0 108: w1 += -1 109: if w1 > 6 goto -24 <LBB0_5> 110: w0 += w8 111: r7 += 8 112: w8 = w0 113: if r7 != 224 goto -17 <LBB0_8> And source code: for (i = 0; i < ARRAY_SIZE(tcp_mem); ++i) { ret = bpf_strtoul(value + off, MAX_ULONG_STR_LEN, 0, tcp_mem + i); if (ret <= 0 || ret > MAX_ULONG_STR_LEN) return 0; off += ret & MAX_ULONG_STR_LEN; } Current verifier is not able to conclude that register w0 before '+' at insn 110 has a range of 1 to 7 and thinks it is from 0 - 255. This leads to more conservative range for w8 at insn 112, and later verifier complaint. Let us workaround this issue until we found a compiler and/or verifier solution. The workaround in this patch is to make variable 'ret' volatile, which will force a reload and then '&' operation to ensure better value range. With this patch, I got the below byte code for the loop: 0000000000000328 LBB0_9: 101: r4 = r10 102: r4 += -288 103: r4 += r7 104: w8 &= 255 105: r1 = r10 106: r1 += -488 107: r1 += r8 108: r2 = 7 109: r3 = 0 110: call 106 111: *(u32 *)(r10 - 64) = r0 112: r1 = *(u32 *)(r10 - 64) 113: if w1 s< 1 goto -28 <LBB0_5> 114: r1 = *(u32 *)(r10 - 64) 115: if w1 s> 7 goto -30 <LBB0_5> 116: r1 = *(u32 *)(r10 - 64) 117: w1 &= 7 118: w1 += w8 119: r7 += 8 120: w8 = w1 121: if r7 != 224 goto -21 <LBB0_9> Insn 117 did the '&' operation and we got more precise value range for 'w8' at insn 120.

[PATCH linux-kselftest/test v2] apparmor: add AppArmor KUnit tests for policy unpack

by Brendan Higgins

From: Mike Salvatore <mike.salvatore(a)canonical.com> Add KUnit tests to test AppArmor unpacking of userspace policies. AppArmor uses a serialized binary format for loading policies. To find policy format documentation see Documentation/admin-guide/LSM/apparmor.rst. In order to write the tests against the policy unpacking code, some static functions needed to be exposed for testing purposes. One of the goals of this patch is to establish a pattern for which testing these kinds of functions should be done in the future.

[PATCH v2] selftests: fix build behaviour on targets' failures

by Cristian Marussi

Currently, when some of the KSFT subsystems fails to build, the toplevel KSFT Makefile just keeps carrying on with the build process. This behaviour is expected and desirable especially in the context of a CI system running KSelfTest, since it is not always easy to guarantee that the most recent and esoteric dependencies are respected across all KSFT TARGETS in a timely manner. Unfortunately, as of now, this holds true only if the very last of the built subsystems could have been successfully compiled: if the last of those subsystem instead failed to build, such failure is taken as the whole outcome of the Makefile target and the complete build/install process halts even though many other preceding subsytems were in fact already built successfully. Fix the KSFT Makefile behaviour related to all/install targets in order to fail as a whole only when the all/install targets have failed for all of the requested TARGETS, while succeeding when at least one of TARGETS has been successfully built. Signed-off-by: Cristian Marussi <cristian.marussi(a)arm.com> --- This patch is based on ksft/fixes branch from: git://git.kernel.org/pub/scm/linux/kernel/git/shuah/linux-kselftest.git on top of commit (~5.5-rc1): 99e51aa8f701 Documentation: kunit: add documentation for kunit_tool Building with either: make kselftest-install \ KSFT_INSTALL_PATH=/tmp/KSFT \ TARGETS="exec arm64 bpf" make -C tools/testing/selftests install \ KSFT_INSTALL_PATH=/tmp/KSFT \ TARGETS="exec arm64 bpf" (with 'bpf' not building clean on my setup in the above case) and veryfying that build/install completes if at least one of TARGETS can be successfully built, and any successfully built subsystem is installed.

[PATCH 0/3] Reanme the definitions of INTERRUPT_PENDING, NMI_PENDING and TSC_OFFSETING

by Xiaoyao Li

When reading the codes, I find the definitions of interrupt-window exiting and nmi-window exiting don't match the names in latest intel SDM. I have no idea whether it's the historical names, rename them to match the latest SDM to avoid confusion. CPU_BASED_USE_TSC_OFFSETING mis-spelling in Patch 3 is found by checkpatch.pl.

[PATCH] selftests: net: ip_defrag: increase netdev_max_backlog

by Thadeu Lima de Souza Cascardo

When using fragments with size 8 and payload larger than 8000, the backlog might fill up and packets will be dropped, causing the test to fail. This happens often enough when conntrack is on during the IPv6 test. As the larger payload in the test is 10000, using a backlog of 1250 allow the test to run repeatedly without failure. At least a 1000 runs were possible with no failures, when usually less than 50 runs were good enough for showing a failure. As netdev_max_backlog is not a pernet setting, this sets the backlog to 1000 during exit to prevent disturbing following tests.

[PATCH v18 00/13] open: introduce openat2(2) syscall

by Aleksa Sarai

This patchset is being developed here: <https://github.com/cyphar/linux/tree/openat2/master> Patch changelog: v18: * Further fixups from Al Viro: - Don't WARN_ON in complete_walk() check since it can be trivially triggered by userspace. Also, improve the comment so the purpose of the check is more clear. - Avoid duplicate smp_rmb() when in handle_dots() by doing __read_seqcount_retry(). - Drop vestigial UPGRADE_NO* flag definitions in uapi. * Update non-zero __padding test to include all bytes of the padding. v17: <https://lore.kernel.org/lkml/20191117011713.13032-1-cyphar@cyphar.com/> <https://lore.kernel.org/lkml/20191120050631.12816-1-cyphar@cyphar.com/> v16: <https://lore.kernel.org/lkml/20191116002802.6663-1-cyphar@cyphar.com/> v15: <https://lore.kernel.org/lkml/20191105090553.6350-1-cyphar@cyphar.com/> v14: <https://lore.kernel.org/lkml/20191010054140.8483-1-cyphar@cyphar.com/> <https://lore.kernel.org/lkml/20191026185700.10708-1-cyphar@cyphar.com> v13: <https://lore.kernel.org/lkml/20190930183316.10190-1-cyphar@cyphar.com/> v12: <https://lore.kernel.org/lkml/20190904201933.10736-1-cyphar@cyphar.com/> v11: <https://lore.kernel.org/lkml/20190820033406.29796-1-cyphar@cyphar.com/> <https://lore.kernel.org/lkml/20190728010207.9781-1-cyphar@cyphar.com/> v10: <https://lore.kernel.org/lkml/20190719164225.27083-1-cyphar@cyphar.com/> v09: <https://lore.kernel.org/lkml/20190706145737.5299-1-cyphar@cyphar.com/> v08: <https://lore.kernel.org/lkml/20190520133305.11925-1-cyphar@cyphar.com/> v07: <https://lore.kernel.org/lkml/20190507164317.13562-1-cyphar@cyphar.com/> v06: <https://lore.kernel.org/lkml/20190506165439.9155-1-cyphar@cyphar.com/> v05: <https://lore.kernel.org/lkml/20190320143717.2523-1-cyphar@cyphar.com/> v04: <https://lore.kernel.org/lkml/20181112142654.341-1-cyphar@cyphar.com/> v03: <https://lore.kernel.org/lkml/20181009070230.12884-1-cyphar@cyphar.com/> v02: <https://lore.kernel.org/lkml/20181009065300.11053-1-cyphar@cyphar.com/> v01: <https://lore.kernel.org/lkml/20180929103453.12025-1-cyphar@cyphar.com/> For a very long time, extending openat(2) with new features has been incredibly frustrating. This stems from the fact that openat(2) is possibly the most famous counter-example to the mantra "don't silently accept garbage from userspace" -- it doesn't check whether unknown flags are present[1]. This means that (generally) the addition of new flags to openat(2) has been fraught with backwards-compatibility issues (O_TMPFILE has to be defined as __O_TMPFILE|O_DIRECTORY|[O_RDWR or O_WRONLY] to ensure old kernels gave errors, since it's insecure to silently ignore the flag[2]). All new security-related flags therefore have a tough road to being added to openat(2). Furthermore, the need for some sort of control over VFS's path resolution (to avoid malicious paths resulting in inadvertent breakouts) has been a very long-standing desire of many userspace applications. This patchset is a revival of Al Viro's old AT_NO_JUMPS[3] patchset (which was a variant of David Drysdale's O_BENEATH patchset[4] which was a spin-off of the Capsicum project[5]) with a few additions and changes made based on the previous discussion within [6] as well as others I felt were useful. In line with the conclusions of the original discussion of AT_NO_JUMPS, the flag has been split up into separate flags. However, instead of being an openat(2) flag it is provided through a new syscall openat2(2) which provides several other improvements to the openat(2) interface (see the patch description for more details). The following new LOOKUP_* flags are added: * LOOKUP_NO_XDEV blocks all mountpoint crossings (upwards, downwards, or through absolute links). Absolute pathnames alone in openat(2) do not trigger this. Magic-link traversal which implies a vfsmount jump is also blocked (though magic-link jumps on the same vfsmount are permitted). * LOOKUP_NO_MAGICLINKS blocks resolution through /proc/$pid/fd-style links. This is done by blocking the usage of nd_jump_link() during resolution in a filesystem. The term "magic-links" is used to match with the only reference to these links in Documentation/, but I'm happy to change the name. It should be noted that this is different to the scope of ~LOOKUP_FOLLOW in that it applies to all path components. However, you can do openat2(NO_FOLLOW|NO_MAGICLINKS) on a magic-link and it will *not* fail (assuming that no parent component was a magic-link), and you will have an fd for the magic-link. In order to correctly detect magic-links, the introduction of a new LOOKUP_MAGICLINK_JUMPED state flag was required. * LOOKUP_BENEATH disallows escapes to outside the starting dirfd's tree, using techniques such as ".." or absolute links. Absolute paths in openat(2) are also disallowed. Conceptually this flag is to ensure you "stay below" a certain point in the filesystem tree -- but this requires some additional to protect against various races that would allow escape using "..". Currently LOOKUP_BENEATH implies LOOKUP_NO_MAGICLINKS, because it can trivially beam you around the filesystem (breaking the protection). In future, there might be similar safety checks done as in LOOKUP_IN_ROOT, but that requires more discussion. In addition, two new flags are added that expand on the above ideas: * LOOKUP_NO_SYMLINKS does what it says on the tin. No symlink resolution is allowed at all, including magic-links. Just as with LOOKUP_NO_MAGICLINKS this can still be used with NOFOLLOW to open an fd for the symlink as long as no parent path had a symlink component. * LOOKUP_IN_ROOT is an extension of LOOKUP_BENEATH that, rather than blocking attempts to move past the root, forces all such movements to be scoped to the starting point. This provides chroot(2)-like protection but without the cost of a chroot(2) for each filesystem operation, as well as being safe against race attacks that chroot(2) is not. If a race is detected (as with LOOKUP_BENEATH) then an error is generated, and similar to LOOKUP_BENEATH it is not permitted to cross magic-links with LOOKUP_IN_ROOT. The primary need for this is from container runtimes, which currently need to do symlink scoping in userspace[7] when opening paths in a potentially malicious container. There is a long list of CVEs that could have bene mitigated by having RESOLVE_THIS_ROOT (such as CVE-2017-1002101, CVE-2017-1002102, CVE-2018-15664, and CVE-2019-5736, just to name a few). In order to make all of the above more usable, I'm working on libpathrs[8] which is a C-friendly library for safe path resolution. It features a userspace-emulated backend if the kernel doesn't support openat2(2). Hopefully we can get userspace to switch to using it, and thus get openat2(2) support for free once it's ready. Future work would include implementing things like RESOLVE_NO_AUTOMOUNT and possibly a RESOLVE_NO_REMOTE (to allow programs to be sure they don't hit DoSes though stale NFS handles).

DESCRIPTION The openat2() system call opens the file specified by pathname. If the specified file does not exist, it may optionally (if O_CREAT is specified in how.flags) be created by openat2(). As with openat(2), if pathname is relative, then it is interpreted relative to the directory referred to by the file descriptor dirfd (or the current working directory of the calling process, if dirfd is the special value AT_FDCWD.) If pathname is absolute, then dirfd is ignored (unless how.resolve contains RESOLVE_IN_ROOT, in which case pathname is resolved relative to dirfd.) The openat2() system call is an extension of openat(2) and provides a superset of its functionality. Rather than taking a single flag argument, an extensible structure (how) is passed instead to allow for future exten- sions. size must be set to sizeof(struct open_how), to facilitate future extensions (see the "Extensibility" section of the NOTES for more detail on how extensions are handled.) The open_how structure The following structure indicates how pathname should be opened, and acts as a superset of the flag and mode arguments to openat(2). struct open_how { __aligned_u64 flags; /* O_* flags. */ __u16 mode; /* Mode for O_{CREAT,TMPFILE}. */ __u16 __padding[3]; /* Must be zeroed. */ __aligned_u64 resolve; /* RESOLVE_* flags. */ }; Any future extensions to openat2() will be implemented as new fields appended to the above structure (or through reuse of pre-existing padding space), with the zero value of the new fields acting as though the ex- tension were not present. The meaning of each field is as follows: flags The file creation and status flags to use for this operation. All of the O_* flags defined for openat(2) are valid openat2() flag values. Unlike openat(2), it is an error to provide openat2() unknown or conflicting flags in flags. mode File mode for the new file, with identical semantics to the mode argument to openat(2). How- ever, unlike openat(2), it is an error to provide openat2() with a mode which contains bits other than 0777. It is an error to provide openat2() a non-zero mode if flags does not contain O_CREAT or O_TMP- FILE. resolve Change how the components of pathname will be resolved (see path_resolution(7) for background information.) The primary use case for these flags is to allow trusted programs to restrict how untrusted paths (or paths inside untrusted directories) are resolved. The full list of resolve flags is given below. RESOLVE_NO_XDEV Disallow traversal of mount points during path resolution (including all bind mounts). Users of this flag are encouraged to make its use configurable (unless it is used for a specific security purpose), as bind mounts are very widely used by end-users. Setting this flag indiscrimnately for all uses of openat2() may result in spurious errors on pre- viously-functional systems. RESOLVE_NO_SYMLINKS Disallow resolution of symbolic links during path resolution. This option implies RE- SOLVE_NO_MAGICLINKS. If the trailing component is a symbolic link, and flags contains both O_PATH and O_NOFOL- LOW, then an O_PATH file descriptor referencing the symbolic link will be returned. Users of this flag are encouraged to make its use configurable (unless it is used for a specific security purpose), as symbolic links are very widely used by end-users. Setting this flag indiscrimnately for all uses of openat2() may result in spurious errors on pre- viously-functional systems. RESOLVE_NO_MAGICLINKS Disallow all magic link resolution during path resolution. If the trailing component is a magic link, and flags contains both O_PATH and O_NOFOLLOW, then an O_PATH file descriptor referencing the magic link will be returned. Magic-links are symbolic link-like objects that are most notably found in proc(5) (exam- ples include /proc/[pid]/exe and /proc/[pid]/fd/*.) Due to the potential danger of un- knowingly opening these magic links, it may be preferable for users to disable their res- olution entirely (see symboliclink(7) for more details.) RESOLVE_BENEATH Do not permit the path resolution to succeed if any component of the resolution is not a descendant of the directory indicated by dirfd. This results in absolute symbolic links (and absolute values of pathname) to be rejected. Currently, this flag also disables magic link resolution. However, this may change in the future. The caller should explicitly specify RESOLVE_NO_MAGICLINKS to ensure that magic links are not resolved. RESOLVE_IN_ROOT Treat dirfd as the root directory while resolving pathname (as though the user called ch- root(2) with dirfd as the argument.) Absolute symbolic links and ".." path components will be scoped to dirfd. If pathname is an absolute path, it is also treated relative to dirfd. However, unlike chroot(2) (which changes the filesystem root permanently for a process), RESOLVE_IN_ROOT allows a program to efficiently restrict path resolution for only certain operations. It also has several hardening features (such detecting escape attempts dur- ing .. resolution) which chroot(2) does not. Currently, this flag also disables magic link resolution. However, this may change in the future. The caller should explicitly specify RESOLVE_NO_MAGICLINKS to ensure that magic links are not resolved. It is an error to provide openat2() unknown flags in resolve. RETURN VALUE On success, a new file descriptor is returned. On error, -1 is returned, and errno is set appropriately. ERRORS The set of errors returned by openat2() includes all of the errors returned by openat(2), as well as the fol- lowing additional errors: EINVAL An unknown flag or invalid value was specified in how. EINVAL mode is non-zero, but flags does not contain O_CREAT or O_TMPFILE. EINVAL size was smaller than any known version of struct open_how. E2BIG An extension was specified in how, which the current kernel does not support (see the "Extensibility" section of the NOTES for more detail on how extensions are handled.) EAGAIN resolve contains either RESOLVE_IN_ROOT or RESOLVE_BENEATH, and the kernel could not ensure that a ".." component didn't escape (due to a race condition or potential attack.) Callers may choose to retry the openat2() call. EXDEV resolve contains either RESOLVE_IN_ROOT or RESOLVE_BENEATH, and an escape from the root during path resolution was detected. EXDEV resolve contains RESOLVE_NO_XDEV, and a path component attempted to cross a mount point. ELOOP resolve contains RESOLVE_NO_SYMLINKS, and one of the path components was a symbolic link (or magic link). ELOOP resolve contains RESOLVE_NO_MAGICLINKS, and one of the path components was a magic link. VERSIONS openat2() first appeared in Linux 5.6. CONFORMING TO This system call is Linux-specific. The semantics of RESOLVE_BENEATH were modelled after FreeBSD's O_BENEATH. NOTES Glibc does not provide a wrapper for this system call; call it using syscall(2). Extensibility In order to allow for struct open_how to be extended in future kernel revisions, openat2() requires userspace to specify the size of struct open_how structure they are passing. By providing this information, it is pos- sible for openat2() to provide both forwards- and backwards-compatibility — with size acting as an implicit version number (because new extension fields will always be appended, the size will always increase.) This extensibility design is very similar to other system calls such as perf_setattr(2), perf_event_open(2), and clone(3). If we let usize be the size of the structure according to userspace and ksize be the size of the structure which the kernel supports, then there are only three cases to consider: * If ksize equals usize, then there is no version mismatch and how can be used verbatim. * If ksize is larger than usize, then there are some extensions the kernel supports which the userspace program is unaware of. Because all extensions must have their zero values be a no-op, the kernel treats all of the extension fields not set by userspace to have zero values. This provides backwards-compatibility. * If ksize is smaller than usize, then there are some extensions which the userspace program is aware of but the kernel does not support. Because all extensions must have their zero values be a no-op, the kernel can safely ignore the unsupported extension fields if they are all-zero. If any unsup- ported extension fields are non-zero, then -1 is returned and errno is set to E2BIG. This provides forwards-compatibility. Therefore, most userspace programs will not need to have any special handling of extensions. However, if a userspace program wishes to determine what extensions the running kernel supports, they may conduct a binary search on size (to find the largest value which doesn't produce an error of E2BIG.)

[PATCH v5 linux-kselftest-test 0/6] kunit: support building core/tests as modules

by Alan Maguire

The current kunit execution model is to provide base kunit functionality and tests built-in to the kernel. The aim of this series is to allow building kunit itself and tests as modules. This in turn allows a simple form of selective execution; load the module you wish to test. In doing so, kunit itself (if also built as a module) will be loaded as an implicit dependency. Because this requires a core API modification - if a module delivers multiple suites, they must be declared with the kunit_test_suites() macro - we're proposing this patch set as a candidate to be applied to the test tree before too many kunit consumers appear. We attempt to deal with existing consumers in patch 3. Changes since v4: - fixed signoff chain to use Co-developed-by: prior to Knut's signoff (Stephen, all patches) - added Reviewed-by, Tested-by for patches 1, 2, 4 and 6 - updated comment describing try-catch-impl.h (Stephen, patch 2) - fixed MODULE_LICENSEs to be GPL v2 (Stephen, patches 3, 5) - added __init to kunit_init() (Stephen, patch 5) Changes since v3: - removed symbol lookup patch for separate submission later - removed use of sysctl_hung_task_timeout_seconds (patch 4, as discussed with Brendan and Stephen) - disabled build of string-stream-test when CONFIG_KUNIT_TEST=m; this is to avoid having to deal with symbol lookup issues - changed string-stream-impl.h back to string-stream.h (Brendan) - added module build support to new list, ext4 tests Changes since v2: - moved string-stream.h header to lib/kunit/string-stream-impl.h (Brendan) (patch 1) - split out non-exported interfaces in try-catch-impl.h (Brendan) (patch 2) - added kunit_find_symbol() and KUNIT_INIT_SYMBOL to lookup non-exported symbols (patches 3, 4) - removed #ifdef MODULE around module licenses (Randy, Brendan, Andy) (patch 4) - replaced kunit_test_suite() with kunit_test_suites() rather than supporting both (Brendan) (patch 4) - lookup sysctl_hung_task_timeout_secs as kunit may be built as a module and the symbol may not be available (patch 5) Alan Maguire (6): kunit: move string-stream.h to lib/kunit kunit: hide unexported try-catch interface in try-catch-impl.h kunit: allow kunit tests to be loaded as a module kunit: remove timeout dependence on sysctl_hung_task_timeout_seconds kunit: allow kunit to be loaded as a module kunit: update documentation to describe module-based build Documentation/dev-tools/kunit/faq.rst | 3 +- Documentation/dev-tools/kunit/index.rst | 3 ++ Documentation/dev-tools/kunit/usage.rst | 16 ++++++++++ fs/ext4/Kconfig | 2 +- fs/ext4/Makefile | 5 +++ fs/ext4/inode-test.c | 4 ++- include/kunit/assert.h | 3 +- include/kunit/test.h | 35 ++++++++++++++------ include/kunit/try-catch.h | 10 ------ kernel/sysctl-test.c | 4 ++- lib/Kconfig.debug | 4 +-- lib/kunit/Kconfig | 6 ++-- lib/kunit/Makefile | 14 +++++--- lib/kunit/assert.c | 10 ++++++ lib/kunit/{example-test.c => kunit-example-test.c} | 4 ++- lib/kunit/{test-test.c => kunit-test.c} | 7 ++-- lib/kunit/string-stream-test.c | 5 +-- lib/kunit/string-stream.c | 3 +- {include => lib}/kunit/string-stream.h | 0 lib/kunit/test.c | 25 ++++++++++++++- lib/kunit/try-catch-impl.h | 27 ++++++++++++++++ lib/kunit/try-catch.c | 37 +++++----------------- lib/list-test.c | 4 ++- 23 files changed, 160 insertions(+), 71 deletions(-) rename lib/kunit/{example-test.c => kunit-example-test.c} (97%) rename lib/kunit/{test-test.c => kunit-test.c} (98%) rename {include => lib}/kunit/string-stream.h (100%) create mode 100644 lib/kunit/try-catch-impl.h -- 1.8.3.1

selftests: l2tp tests

by Colin Ian King

Hi, While testing linux 5.4 with the l2tp test I discovered two kernel issues when running this test: 1. About 10+ seconds after completing the test one can observe periodic kernel log messages from netdev_wait_allrefs (in net/core/dev.c) in the form: "unregister_netdevice: waiting for eth0 to become free. Usage count = 1" 2. Our regression tests that ran stress-ng after this test picked up another issue that causes socket() to hang indefinitely. I've managed to get this down to a simple reproducer as follows: sudo modprobe l2tp_core sudo ./linux/tools/testing/selftests/net/l2tp.sh sleep 5 ./close Where ./close is an executable compiled from: #include <sys/types.h> #include <sys/socket.h> #include <unistd.h> #include <stdio.h> int main() { int fd; printf("calling socket..\n"); fd = socket(AF_APPLETALK, SOCK_STREAM, 0); printf("socket returned: %d\n", fd); } The code will hang on the socket() call and won't ever get to the final print statement. If one runs the reproducer on earlier kernels we get: 4.6.7 crash (see dmesg below) 4.7.10 crash in xfrm6_dst_ifdown 4.8.17 crash in xfrm6_dst_ifdown 4.12.14 crash (see dmesg below) 4.13.16 reports "unregister_netdevice: waiting for eth0 to become free. Usage count = 2" 4.14.157 reports "unregister_netdevice: waiting for eth0 to become free. Usage count = 2"" 4.15.18 .. 5.4 hangs on socket() call Note: functionality for the l2tp test is not available for pre-4.6 kernels. The crashes I get for older kernels are: 4.6.7: [ 34.457967] BUG: scheduling while atomic: kworker/u8:0/6/0x00000200 [ 34.458021] Modules linked in: esp6 xfrm6_mode_transport drbg ansi_cprng seqiv esp4 xfrm4_mode_transport xfrm_user xfrm_algo l2tp_ip6 l2tp_eth l2tp_ip l2tp_netlink veth l2tp_core ip6_udp_tunnel udp_tunnel squashfs binfmt_misc dm_multipath scsi_dh_rdac scsi_dh_emc scsi_dh_alua ppdev kvm_intel kvm irqbypass joydev input_leds snd_hda_codec_generic serio_raw snd_hda_intel snd_hda_codec parport_pc 8250_fintek parport snd_hda_core qemu_fw_cfg snd_hwdep snd_pcm snd_timer mac_hid snd soundcore sch_fq_codel virtio_rng ip_tables x_tables autofs4 btrfs raid10 raid456 async_raid6_recov async_memcpy async_pq async_xor async_tx xor hid_generic usbhid hid raid6_pq libcrc32c raid1 raid0 multipath linear crct10dif_pclmul crc32_pclmul ghash_clmulni_intel qxl ttm drm_kms_helper syscopyarea sysfillrect aesni_intel sysimgblt [ 34.458086] fb_sys_fops aes_x86_64 lrw gf128mul glue_helper ablk_helper cryptd i2c_piix4 drm psmouse pata_acpi floppy [ 34.458100] CPU: 1 PID: 6 Comm: kworker/u8:0 Not tainted 4.6.7-040607-generic #201608160432 [ 34.458103] Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.12.0-1 04/01/2014 [ 34.458131] Workqueue: netns cleanup_net [ 34.458135] 0000000000000286 000000002fa171e7 ffff88007c8e7ab8 ffffffff813f7594 [ 34.458139] ffff88007fc96b80 7fffffffffffffff ffff88007c8e7ac8 ffffffff810a8f6b [ 34.458143] ffff88007c8e7b18 ffffffff8184905b 00ff88007c8e7ae8 ffffffff8106463e [ 34.458147] Call Trace: [ 34.458161] [<ffffffff813f7594>] dump_stack+0x63/0x8f [ 34.458166] [<ffffffff810a8f6b>] __schedule_bug+0x4b/0x60 [ 34.458185] [<ffffffff8184905b>] __schedule+0x5eb/0x7a0 [ 34.458191] [<ffffffff8106463e>] ? kvm_sched_clock_read+0x1e/0x30 [ 34.458195] [<ffffffff81849245>] schedule+0x35/0x80 [ 34.458203] [<ffffffff8184c402>] schedule_timeout+0x1b2/0x270 [ 34.458207] [<ffffffff81848d74>] ? __schedule+0x304/0x7a0 [ 34.458212] [<ffffffff81849ca3>] wait_for_completion+0xb3/0x140 [ 34.458217] [<ffffffff810aeed0>] ? wake_up_q+0x70/0x70 [ 34.458226] [<ffffffff810e7f68>] __wait_rcu_gp+0xc8/0xf0 [ 34.458231] [<ffffffff810e9fd8>] synchronize_sched.part.58+0x38/0x50 [ 34.458235] [<ffffffff810ec570>] ? call_rcu_bh+0x20/0x20 [ 34.458239] [<ffffffff810e7e80>] ? trace_raw_output_rcu_utilization+0x60/0x60 [ 34.458244] [<ffffffff810ec643>] synchronize_sched+0x33/0x40 [ 34.458251] [<ffffffffc0510f71>] __l2tp_session_unhash+0xd1/0xe0 [l2tp_core] [ 34.458256] [<ffffffffc051101e>] l2tp_tunnel_closeall+0x9e/0x140 [l2tp_core] [ 34.458261] [<ffffffffc0511219>] l2tp_tunnel_delete+0x19/0x70 [l2tp_core] [ 34.458265] [<ffffffffc05112bb>] l2tp_exit_net+0x4b/0x80 [l2tp_core] [ 34.458269] [<ffffffff81732188>] ops_exit_list.isra.4+0x38/0x60 [ 34.458273] [<ffffffff817331e4>] cleanup_net+0x1c4/0x2a0 [ 34.458281] [<ffffffff8109ccfc>] process_one_work+0x1fc/0x490 [ 34.458285] [<ffffffff8109cfdb>] worker_thread+0x4b/0x500 [ 34.458290] [<ffffffff8109cf90>] ? process_one_work+0x490/0x490 [ 34.458293] [<ffffffff810a37c8>] kthread+0xd8/0xf0 [ 34.458298] [<ffffffff8184d522>] ret_from_fork+0x22/0x40 [ 34.458302] [<ffffffff810a36f0>] ? kthread_create_on_node+0x1b0/0x1b0 [ 34.514067] ------------[ cut here ]------------ 4.12.14: [ 20.760253] ------------[ cut here ]------------ [ 20.760256] kernel BUG at /home/kernel/COD/linux/net/ipv6/xfrm6_policy.c:265!

[PATCH v7 00/25] Unify vDSOs across more architectures

by Vincenzo Frascino

vDSO (virtual dynamic shared object) is a mechanism that the Linux kernel provides as an alternative to system calls to reduce where possible the costs in terms of cycles. This is possible because certain syscalls like gettimeofday() do not write any data and return one or more values that are stored in the kernel, which makes relatively safe calling them directly as a library function. Even if the mechanism is pretty much standard, every architecture in the last few years ended up implementing their own vDSO library in the architectural code. The purpose of this patch-set is to identify the commonalities in between the architectures and try to consolidate the common code paths, starting with gettimeofday(). This implementation contains the following design choices: * Every architecture defines the arch specific code in an header in "asm/vdso/". * The generic implementation includes the arch specific one and lives in "lib/vdso". * The arch specific code for gettimeofday lives in "<arch path>/vdso/gettimeofday.c" and includes the generic code only. * The generic implementation of update_vsyscall and update_vsyscall_tz lives in kernel/vdso and provide the bindings that can be implemented by each architecture. * Each architecture provides its implementation of the bindings in "asm/vdso/vsyscall.h". * This approach allows to consolidate the common code in a single place with the benefit of avoiding code duplication. This implementation contains the portings to the common library for: arm64, compat mode for arm64, arm, mips, x86_64, x32, compat mode for x86_64 and i386. The mips porting has been tested on qemu for mips32el. A configuration to repeat the tests can be found at [4]. The x86_64 porting has been tested on an Intel Xeon 5120T based machine running Ubuntu 18.04 and using the Ubuntu provided defconfig. The i386 porting has been tested on qemu using the i386_defconfig configuration. Last but not least from this porting arm64, compat arm64, arm and mips gain the support for: * CLOCK_BOOTTIME that can be useful in certain scenarios since it keeps track of the time during sleep as well. * CLOCK_TAI that is like CLOCK_REALTIME, but uses the International Atomic Time (TAI) reference instead of UTC to avoid jumping on leap second updates. for both clock_gettime and clock_getres. The porting has been validated using the vdsotest test-suite [1] extended to cover all the clock ids [2]. A new test has been added to the linux kselftest in order to validate the newly added library. The porting has been benchmarked and the performance results are provided as part of this cover letter. To simplify the testing, a copy of the patchset on top of a recent linux tree can be found at [3] and [4]. The v7 of this patchseries has been rebased on [5].

git://git.kernel.org/pub/scm/linux/kernel/git/hyperv/linux.git hyperv-next Changes: -------- v7: - Rebased on [5] (5.2-rc3). - Added performance numbers for arm64 provided by Shijith Thotton. - Aimed at 1:1 replacement for pre-exisiting vDSO libraries. - Provided separate patches for newly added API. - Addressed review comments. v6: - Rebased on 5.2-rc2. - Added performance numbers. - Removed vdso_types.h. - Unified update_vsyscall and update_vsyscall_tz. - Reworked the kselftest included in this patchset. - Addressed review comments. v5: - Rebased on 5.0-rc7. - Added x86_64, compat mode for x86_64 and i386 portings. - Extended vDSO kselftest. - Addressed review comments. v4: - Rebased on 5.0-rc2. - Addressed review comments. - Disabled compat vdso on arm64 when the kernel is compiled with clang. v3: - Ported the latest fixes and optimizations done on the x86 architecture to the generic library. - Addressed review comments. - Improved the documentation of the interfaces. - Changed the HAVE_ARCH_TIMER config option to a more generic HAVE_HW_COUNTER. v2: - Added -ffixed-x18 to arm64 - Repleced occurrences of timeval and timespec - Modified datapage.h to be compliant with y2038 on all the architectures - Removed __u_vdso type Cc: Catalin Marinas <catalin.marinas(a)arm.com> Cc: Will Deacon <will.deacon(a)arm.com> Cc: Arnd Bergmann <arnd(a)arndb.de> Cc: Russell King

[BUGFIX PATCH] selftests/x86: Check the availablity of sys/syscall.h

by Masami Hiramatsu

Since single_step_syscall.c depends on sys/syscall.h and its include, asm/unistd.h, we should check the availability of those headers. Without this fix, if gcc-multilib is not installed but libc6-dev-i386 is installed, kselftest tries to build 32bit binary and failed with following error message. In file included from single_step_syscall.c:18: /usr/include/sys/syscall.h:24:10: fatal error: asm/unistd.h: No such file or directory #include <asm/unistd.h> ^~~~~~~~~~~~~~ compilation terminated.
