[PATCH v4 0/4] introduce PIDFD_SELF* sentinels

by Lorenzo Stoakes

If you wish to utilise a pidfd interface to refer to the current process or thread it is rather cumbersome, requiring something like: int pidfd = pidfd_open(getpid(), 0 or PIDFD_THREAD); ... close(pidfd); Or the equivalent call opening /proc/self. It is more convenient to use a sentinel value to indicate to an interface that accepts a pidfd that we simply wish to refer to the current process thread. This series introduces sentinels for this purposes which can be passed as the pidfd in this instance rather than having to establish a dummy fd for this purpose. It is useful to refer to both the current thread from the userland's perspective for which we use PIDFD_SELF, and the current process from the userland's perspective, for which we use PIDFD_SELF_PROCESS. There is unfortunately some confusion between the kernel and userland as to what constitutes a process - a thread from the userland perspective is a process in userland, and a userland process is a thread group (more specifically the thread group leader from the kernel perspective). We therefore alias things thusly: * PIDFD_SELF_THREAD aliased by PIDFD_SELF - use PIDTYPE_PID. * PIDFD_SELF_THREAD_GROUP alised by PIDFD_SELF_PROCESS - use PIDTYPE_TGID. In all of the kernel code we refer to PIDFD_SELF_THREAD and PIDFD_SELF_THREAD_GROUP. However we expect users to use PIDFD_SELF and PIDFD_SELF_PROCESS. This matters for cases where, for instance, a user unshare()'s FDs or does thread-specific signal handling and where the user would be hugely confused if the FDs referenced or signal processed referred to the thread group leader rather than the individual thread. We ensure that pidfd_send_signal() and pidfd_getfd() work correctly, and assert as much in selftests. All other interfaces except setns() will work implicitly with this new interface, however it doesn't make sense to test waitid(P_PIDFD, ...) as waiting on ourselves is a blocking operation. In the case of setns() we explicitly disallow use of PIDFD_SELF* as it doesn't make sense to obtain the namespaces of our own process, and it would require work to implement this functionality there that would be of no use. We also do not provide the ability to utilise PIDFD_SELF* in ordinary fd operations such as open() or poll(), as this would require extensive work and be of no real use. v4: * Avoid returning an fd in the __pidfd_get_pid() function as pointed out by Christian, instead simply always pin the pid and maintain fd scope in the helper alone. * Add wrapper header file in tools/include/linux to allow for import of UAPI pidfd.h header without encountering the collision between system fcntl.h and linux/fcntl.h as discussed with Shuah and John. * Fixup tests to import the UAPI pidfd.h header working around conflicts between system fcntl.h and linux/fcntl.h which the UAPI pidfd.h imports, as reported by Shuah. * Use an int for pidfd_is_self_sentinel() to avoid any dependency on stdbool.h in userland. v3: * Do not fput() an invalid fd as reported by kernel test bot. * Fix unintended churn from moving variable declaration. https://lore.kernel.org/linux-mm/cover.1729073310.git.lorenzo.stoakes@oracl… v2: * Fix tests as reported by Shuah. * Correct RFC version lore link. https://lore.kernel.org/linux-mm/cover.1728643714.git.lorenzo.stoakes@oracl… Non-RFC v1: * Removed RFC tag - there seems to be general consensus that this change is a good idea, but perhaps some debate to be had on implementation. It seems sensible then to move forward with the RFC flag removed. * Introduced PIDFD_SELF_THREAD, PIDFD_SELF_THREAD_GROUP and their aliases PIDFD_SELF and PIDFD_SELF_PROCESS respectively. * Updated testing accordingly. https://lore.kernel.org/linux-mm/cover.1728578231.git.lorenzo.stoakes@oracl… RFC version: https://lore.kernel.org/linux-mm/cover.1727644404.git.lorenzo.stoakes@oracl… Lorenzo Stoakes (4): pidfd: extend pidfd_get_pid() and de-duplicate pid lookup pidfd: add PIDFD_SELF_* sentinels to refer to own thread/process selftests: pidfd: add pidfd.h UAPI wrapper selftests: pidfd: add tests for PIDFD_SELF_* include/linux/pid.h | 34 ++++- include/uapi/linux/pidfd.h | 15 ++ kernel/exit.c | 3 +- kernel/nsproxy.c | 1 + kernel/pid.c | 65 +++++--- kernel/signal.c | 29 +--- tools/include/linux/pidfd.h | 14 ++ tools/testing/selftests/pidfd/Makefile | 3 +- tools/testing/selftests/pidfd/pidfd.h | 2 + .../selftests/pidfd/pidfd_getfd_test.c | 141 ++++++++++++++++++ .../selftests/pidfd/pidfd_setns_test.c | 11 ++ tools/testing/selftests/pidfd/pidfd_test.c | 76 ++++++++-- 12 files changed, 333 insertions(+), 61 deletions(-) create mode 100644 tools/include/linux/pidfd.h -- 2.46.2

[PATCH] selftests: Add kselftest framework to the testfile

by Shivam Chaudhary

This patch updates the existing test that checks for `open(O_TMPFILE)` and `linkat()` behaviors in mount namespaces to use the kselftest framework. This includes the following changes: - Replaced direct error handling with `ksft_test_result_*` macros for better reporting of test outcomes. - Added `ksft_print_header()` and `ksft_set_plan()` to structure test outputs more effectively. - Introduced the helper function `is_unshare()` to handle unshare-related checks. - Improved the test flow by adding more detailed pass/fail reporting for unshare, mounting, file opening, and linking operations. - Skips the test if it's not run as root, providing an appropriate Warning. Test logs: Before change: - Withou root error: unshare, errno 1 - With root No, output After change: - Without root TAP version 13 1..1 ok 1 # SKIP This test needs root to ru - With root TAP version 13 1..1 ok 1 unshare(): we have a new mount namespace. 1..2 ok 2 mount(): Root filesystem private mount: Success 1..3 ok 3 mount(): Mounting tmpfs on /tmp: Success 1..4 ok 4 openat(): Open first temporary file: Success 1..5 ok 5 linkat(): Linking the temporary file: Success 1..6 ok 6 openat(): Opening the second temporary file: Success # Totals: pass:6 fail:0 xfail:0 xpass:0 skip:0 error:0 Signed-off-by: Shivam Chaudhary <cvam0000(a)gmail.com> --- .../selftests/tmpfs/bug-link-o-tmpfile.c | 72 +++++++++++++++---- 1 file changed, 58 insertions(+), 14 deletions(-) diff --git a/tools/testing/selftests/tmpfs/bug-link-o-tmpfile.c b/tools/testing/selftests/tmpfs/bug-link-o-tmpfile.c index b5c3ddb90942..26dea19c1614 100644 --- a/tools/testing/selftests/tmpfs/bug-link-o-tmpfile.c +++ b/tools/testing/selftests/tmpfs/bug-link-o-tmpfile.c @@ -23,45 +23,89 @@ #include <sys/mount.h> #include <unistd.h> -int main(void) -{ - int fd; +#include "../kselftest.h" - if (unshare(CLONE_NEWNS) == -1) { +static int is_unshare(int flag) +{ + if (unshare(flag) == -1) { if (errno == ENOSYS || errno == EPERM) { - fprintf(stderr, "error: unshare, errno %d\n", errno); - return 4; + ksft_test_result_fail("error: unshare, errno %d\n", errno); + return -1; // Return -1 for failure } fprintf(stderr, "error: unshare, errno %d\n", errno); + return -1; + } + + return 0; // Return 0 for success +} + +int main(void) +{ + int fd; + + // Setting up kselftest framework + ksft_print_header(); + ksft_set_plan(1); + + // Check if test is run as root + if (geteuid()) { + ksft_test_result_skip("This test needs root to run!\n"); return 1; } - if (mount(NULL, "/", NULL, MS_PRIVATE|MS_REC, NULL) == -1) { - fprintf(stderr, "error: mount '/', errno %d\n", errno); + + if (is_unshare(CLONE_NEWNS) == 0) { + ksft_test_result_pass("unshare(): we have a new mount namespace.\n"); + } else { + ksft_test_result_fail("unshare(): failed\n"); return 1; } + ksft_set_plan(2); + + if (mount(NULL, "/", NULL, MS_PRIVATE | MS_REC, NULL) == -1) { + ksft_test_result_fail("mount(): Root filesystem private mount: Fail %d\n", errno); + return 1; + } else { + ksft_test_result_pass("mount(): Root filesystem private mount: Success\n"); + } + + ksft_set_plan(3); /* Our heroes: 1 root inode, 1 O_TMPFILE inode, 1 permanent inode. */ if (mount(NULL, "/tmp", "tmpfs", 0, "nr_inodes=3") == -1) { - fprintf(stderr, "error: mount tmpfs, errno %d\n", errno); + ksft_test_result_fail("mount(): Mounting tmpfs on /tmp: Fail %d\n", errno); return 1; + } else { + ksft_test_result_pass("mount(): Mounting tmpfs on /tmp: Success\n"); } - fd = openat(AT_FDCWD, "/tmp", O_WRONLY|O_TMPFILE, 0600); + ksft_set_plan(4); + fd = openat(AT_FDCWD, "/tmp", O_WRONLY | O_TMPFILE, 0600); if (fd == -1) { - fprintf(stderr, "error: open 1, errno %d\n", errno); + ksft_test_result_fail("openat(): Open first temporary file: Fail %d\n", errno); return 1; + } else { + ksft_test_result_pass("openat(): Open first temporary file: Success\n"); } + + ksft_set_plan(5); if (linkat(fd, "", AT_FDCWD, "/tmp/1", AT_EMPTY_PATH) == -1) { - fprintf(stderr, "error: linkat, errno %d\n", errno); + ksft_test_result_fail("linkat(): Linking the temporary file: Fail %d\n", errno); + close(fd); // Ensure fd is closed on failure return 1; + } else { + ksft_test_result_pass("linkat(): Linking the temporary file: Success\n"); } close(fd); - fd = openat(AT_FDCWD, "/tmp", O_WRONLY|O_TMPFILE, 0600); + ksft_set_plan(6); + fd = openat(AT_FDCWD, "/tmp", O_WRONLY | O_TMPFILE, 0600); if (fd == -1) { - fprintf(stderr, "error: open 2, errno %d\n", errno); + ksft_test_result_fail("openat(): Opening the second temporary file: Fail %d\n", errno); return 1; + } else { + ksft_test_result_pass("openat(): Opening the second temporary file: Success\n"); } + ksft_exit_pass(); return 0; } -- 2.34.1

[PATCH v5 00/10] riscv: Userspace pointer masking and tagged address ABI

by Samuel Holland

RISC-V defines three extensions for pointer masking[1]: - Smmpm: configured in M-mode, affects M-mode - Smnpm: configured in M-mode, affects the next lower mode (S or U-mode) - Ssnpm: configured in S-mode, affects the next lower mode (VS, VU, or U-mode) This series adds support for configuring Smnpm or Ssnpm (depending on which privilege mode the kernel is running in) to allow pointer masking in userspace (VU or U-mode), extending the PR_SET_TAGGED_ADDR_CTRL API from arm64. Unlike arm64 TBI, userspace pointer masking is not enabled by default on RISC-V. Additionally, the tag width (referred to as PMLEN) is variable, so userspace needs to ask the kernel for a specific tag width, which is interpreted as a lower bound on the number of tag bits. This series also adds support for a tagged address ABI similar to arm64 and x86. Since accesses from the kernel to user memory use the kernel's pointer masking configuration, not the user's, the kernel must untag user pointers in software before dereferencing them. And since the tag width is variable, as with LAM on x86, it must be kept the same across all threads in a process so untagged_addr_remote() can work. [1]: https://github.com/riscv/riscv-j-extension/raw/d70011dde6c2/zjpm-spec.pdf --- This series depends on the per-thread envcfg series in riscv/for-next. This series can be tested in QEMU by applying a patch set[2]. KASAN_SW_TAGS using pointer masking is an independent patch series[3].

[PATCH RFC 0/3] Verify bias functionality for pinctrl_paris driver through new gpio test

by Nícolas F. R. A. Prado

This series was motivated by the regression fixed by 166bf8af9122 ("pinctrl: mediatek: common-v2: Fix broken bias-disable for PULL_PU_PD_RSEL_TYPE"). A bug was introduced in the pinctrl_paris driver which prevented certain pins from having their bias configured. Running this test on the mt8195-tomato platform with the test plan included below[1] shows the test passing with the fix applied, but failing without the fix: With fix: $ ./gpio-setget-config.py TAP version 13 # Using test plan file: ./google,tomato.yaml 1..3 ok 1 pinctrl_paris.34.pull-up ok 2 pinctrl_paris.34.pull-down ok 3 pinctrl_paris.34.disabled # Totals: pass:3 fail:0 xfail:0 xpass:0 skip:0 error:0 Without fix: $ ./gpio-setget-config.py TAP version 13 # Using test plan file: ./google,tomato.yaml 1..3 # Bias doesn't match: Expected pull-up, read pull-down. not ok 1 pinctrl_paris.34.pull-up ok 2 pinctrl_paris.34.pull-down # Bias doesn't match: Expected disabled, read pull-down. not ok 3 pinctrl_paris.34.disabled # Totals: pass:1 fail:2 xfail:0 xpass:0 skip:0 error:0 In order to achieve this, the first patch exposes bias configuration through the GPIO API in the pinctrl_paris driver, patch 2 extends the gpio-mockup-cdev utility for use by patch 3, and patch 3 introduces a new GPIO kselftest that takes a test plan in YAML, which can be tailored per-platform to specify the configurations to test, and sets and gets back each pin configuration to verify that they match and thus that the driver is behaving as expected. Since the GPIO uAPI only allows setting the pin configuration, getting it back is done through pinconf-pins in the pinctrl debugfs folder. The test currently only verifies bias but it would be easy to extend to verify other pin configurations. The test plan YAML file can be customized for each use-case and is platform-dependant. For that reason, only an example is included in patch 3 and the user is supposed to provide their test plan. That said, the aim is to collect test plans for ease of use at [2]. [1] This is the test plan used for mt8195-tomato: - label: "pinctrl_paris" tests: # Pin 34 has type MTK_PULL_PU_PD_RSEL_TYPE and is unused. # Setting bias to MTK_PULL_PU_PD_RSEL_TYPE pins was fixed by # 166bf8af9122 ("pinctrl: mediatek: common-v2: Fix broken bias-disable for PULL_PU_PD_RSEL_TYPE") - pin: 34 bias: "pull-up" - pin: 34 bias: "pull-down" - pin: 34 bias: "disabled" [2] https://github.com/kernelci/platform-test-parameters Signed-off-by: Nícolas F.

This pattern of action plus corresponding defer is bound to come up often, and a dedicated vocabulary to capture it will be handy. tunnel_create() and vlan_create() from forwarding/lib.sh are somewhat opaque and perhaps too kitchen-sinky, so I tried to go in the opposite direction with these ones, and wrapped only the bare minimum to schedule a corresponding cleanup.

[PATCH net-next v2 7/8] selftests: net: lib: Add kill_process

by Petr Machata

A number of selftests run processes in the background and need to kill them afterwards. Instead for everyone to open-code the kill / wait / redirect mantra, add a helper in net/lib.sh.

[PATCH net-next v2 6/8] selftests: net: lib: Move checks from forwarding/lib.sh here

by Petr Machata

For logging to be useful, something has to set RET and retmsg by calling ret_set_ksft_status(). There is a suite of functions to that end in forwarding/lib: check_err, check_fail et.al. Move them to net/lib.sh so that every net test can use them. Existing lib.sh users might be using these same names for their functions. However lib.sh is always sourced near the top of the file (checked), and whatever new definitions will simply override the ones provided by lib.sh.

[PATCH net-next v2 5/8] selftests: net: lib: Move tests_run from forwarding/lib.sh here

by Petr Machata

It would be good to use the same mechanism for scheduling and dispatching general net tests as the many forwarding tests already use. To that end, move the logging helpers to net/lib.sh so that every net test can use them. Existing lib.sh users might be using the name themselves. However lib.sh is always sourced near the top of the file (checked), and whatever new definition will simply override the one provided by lib.sh.
