[PATCH] selftests/watchdog-test: Fix system accidentally reset after watchdog-test

by Li Zhijian

When running watchdog-test with 'make run_tests', the watchdog-test will be terminated by a timeout signal(SIGTERM) due to the test timemout. And then, a system reboot would happen due to watchdog not stop. see the dmesg as below: ``` [ 1367.185172] watchdog: watchdog0: watchdog did not stop! ``` Fix it by registering more signals(including SIGTERM) in watchdog-test, where its signal handler will stop the watchdog. After that # timeout 1 ./watchdog-test Watchdog Ticking Away! . Stopping watchdog ticks...

[PATCH for-next 1/3] selftests/watchdog: add count parameter for watchdog-test

by Li Zhijian

Currently, watchdog-test keep running until it gets a SIGINT. However, when watchdog-test is executed from the kselftests framework, where it launches test via timeout which will send SIGTERM in time up. This could lead to 1. watchdog haven't stop, a watchdog reset is triggered to reboot the OS in silent. 2. kselftests gets an timeout exit code, and judge watchdog-test as 'not ok' This patch is prepare to fix above 2 issues Signed-off-by: Li Zhijian <lizhijian(a)fujitsu.com> --- Hey, Cover letter is here. It's notice that a OS reboot was triggerred after ran the watchdog-test in kselftests framwork 'make run_tests', that's because watchdog-test didn't stop feeding the watchdog after enable it. In addition, current watchdog-test didn't adapt to the kselftests framework which launchs the test with /usr/bin/timeout and no timeout is expected. --- tools/testing/selftests/watchdog/watchdog-test.c | 13 +++++++++---- 1 file changed, 9 insertions(+), 4 deletions(-) diff --git a/tools/testing/selftests/watchdog/watchdog-test.c b/tools/testing/selftests/watchdog/watchdog-test.c index bc71cbca0dde..2f8fd2670897 100644 --- a/tools/testing/selftests/watchdog/watchdog-test.c +++ b/tools/testing/selftests/watchdog/watchdog-test.c @@ -27,7 +27,7 @@ int fd; const char v = 'V'; -static const char sopts[] = "bdehp:st:Tn:NLf:i"; +static const char sopts[] = "bdehp:st:Tn:NLf:c:i"; static const struct option lopts[] = { {"bootstatus", no_argument, NULL, 'b'}, {"disable", no_argument, NULL, 'd'}, @@ -42,6 +42,7 @@ static const struct option lopts[] = { {"gettimeleft", no_argument, NULL, 'L'}, {"file", required_argument, NULL, 'f'}, {"info", no_argument, NULL, 'i'}, + {"count", required_argument, NULL, 'c'}, {NULL, no_argument, NULL, 0x0} }; @@ -95,6 +96,7 @@ static void usage(char *progname) printf(" -n, --pretimeout=T\tSet the pretimeout to T seconds\n"); printf(" -N, --getpretimeout\tGet the pretimeout\n"); printf(" -L, --gettimeleft\tGet the time left until timer expires\n"); + printf(" -c, --count\tStop after feeding the watchdog count times\n"); printf("\n"); printf("Parameters are parsed left-to-right in real-time.\n"); printf("Example: %s -d -t 10 -p 5 -e\n", progname); @@ -174,7 +176,7 @@ int main(int argc, char *argv[]) unsigned int ping_rate = DEFAULT_PING_RATE; int ret; int c; - int oneshot = 0; + int oneshot = 0, stop = 1, count = 0; char *file = "/dev/watchdog"; struct watchdog_info info; int temperature; @@ -307,6 +309,9 @@ int main(int argc, char *argv[]) else printf("WDIOC_GETTIMELEFT error '%s'\n", strerror(errno)); break; + case 'c': + stop = 0; + count = strtoul(optarg, NULL, 0); case 'f': /* Handled above */ break; @@ -336,8 +341,8 @@ int main(int argc, char *argv[]) signal(SIGINT, term); - while (1) { - keep_alive(); + while (stop || count--) { + exit_code = keep_alive(); sleep(ping_rate); } end: -- 2.44.0

[PATCH v3] selftests: tmpfs: Add kselftest support to tmpfs

by Shivam Chaudhary

Add kselftest support for openat, linkat, unshare, mount tests - Replace direct error handling with 'ksft_test_result_*' , 'ksft_print_msg' macros for better reporting. - Add `ksft_print_header()` and `ksft_set_plan()` to structure test outputs more effectively. - Improve the test flow by adding more detailed pass/fail reporting for unshare, mounting, file opening, and linking operations. - Skip the test if it's not run as root, providing an appropriate Warning. Test logs: Before change: - Without 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 run - With root TAP version 13 1..1 unshare(): Creat new mount namespace: Success. mount(): Root filesystem private mount: Success mount(): Mounting tmpfs on /tmp: Success openat(): Open first temporary file: Success linkat(): Linking the temporary file: Success openat(): Opening the second temporary file: Success ok 1 Test : Success Totals: pass:1 fail:0 xfail:0 xpass:0 skip:0 error:0 Signed-off-by: Shivam Chaudhary <cvam0000(a)gmail.com> --- Notes: Changes in v3: - Remove extra ksft_set_plan() - Remove function for unshare() - Fix the comment style link to v2: https://lore.kernel.org/all/20241026191621.2860376-1-cvam0000@gmail.com/ Changes in v2: - Make the commit message more clear. link to v1: https://lore.kernel.org/all/20241024200228.1075840-1-cvam0000@gmail.com/T/#u .../selftests/tmpfs/bug-link-o-tmpfile.c | 69 +++++++++++++++---- 1 file changed, 57 insertions(+), 12 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..9ca1245784d9 100644 --- a/tools/testing/selftests/tmpfs/bug-link-o-tmpfile.c +++ b/tools/testing/selftests/tmpfs/bug-link-o-tmpfile.c @@ -23,45 +23,90 @@ #include <sys/mount.h> #include <unistd.h> +#include "../kselftest.h" + + 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 (unshare(CLONE_NEWNS) == -1) { if (errno == ENOSYS || errno == EPERM) { - fprintf(stderr, "error: unshare, errno %d\n", errno); - return 4; + ksft_test_result_fail("unshare() error: unshare, errno %d\n", errno); + return 1; } - fprintf(stderr, "error: unshare, errno %d\n", errno); - return 1; + else{ + fprintf(stderr, "unshare() error: unshare, errno %d\n", errno); + ksft_test_result_fail("unshare() error: unshare, errno %d\n", errno); + return 1; + + } + } + + else { + ksft_print_msg("unshare(): Creat new mount namespace: Success.\n"); + } - if (mount(NULL, "/", NULL, MS_PRIVATE|MS_REC, NULL) == -1) { - fprintf(stderr, "error: mount '/', errno %d\n", errno); + + + + if (mount(NULL, "/", NULL, MS_PRIVATE | MS_REC, NULL) == -1) { + ksft_test_result_fail("mount() error: Root filesystem private mount: Fail %d\n", errno); return 1; + } else { + ksft_print_msg("mount(): Root filesystem private mount: Success\n"); } + /* 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() error: Mounting tmpfs on /tmp: Fail %d\n", errno); return 1; + } else { + ksft_print_msg("mount(): Mounting tmpfs on /tmp: Success\n"); } - fd = openat(AT_FDCWD, "/tmp", O_WRONLY|O_TMPFILE, 0600); + + 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() error: Open first temporary file: Fail %d\n", errno); return 1; + } else { + ksft_print_msg("openat(): Open first temporary file: Success\n"); } + + if (linkat(fd, "", AT_FDCWD, "/tmp/1", AT_EMPTY_PATH) == -1) { - fprintf(stderr, "error: linkat, errno %d\n", errno); + ksft_test_result_fail("linkat() error: Linking the temporary file: Fail %d\n", errno); + /* Ensure fd is closed on failure */ + close(fd); return 1; + } else { + ksft_print_msg("linkat(): Linking the temporary file: Success\n"); } close(fd); - fd = openat(AT_FDCWD, "/tmp", O_WRONLY|O_TMPFILE, 0600); + + 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() error: Opening the second temporary file: Fail %d\n", errno); return 1; + } else { + ksft_print_msg("openat(): Opening the second temporary file: Success\n"); } + ksft_test_result_pass("Test : Success\n"); + ksft_exit_pass(); return 0; } -- 2.45.2

[PATCH v2] selftests/mount_setattr: fix idmap_mount_tree_invalid failed to run

by zhouyuhang

From: zhouyuhang <zhouyuhang(a)kylinos.cn> Test case idmap_mount_tree_invalid failed to run on the newer kernel with the following output: # RUN mount_setattr_idmapped.idmap_mount_tree_invalid ... # mount_setattr_test.c:1428:idmap_mount_tree_invalid:Expected sys_mount_setattr(open_tree_fd, "", AT_EMPTY_PATH, &attr, sizeof(attr)) (0) ! = 0 (0) # idmap_mount_tree_invalid: Test terminated by assertion This is because tmpfs is mounted at "/mnt/A", and tmpfs already contains the flag FS_ALLOW_IDMAP after the commit 7a80e5b8c6fa ("shmem: support idmapped mounts for tmpfs"). So calling sys_mount_setattr here returns 0 instead of -EINVAL as expected. Ramfs does not support idmap mounts, so we can use it here to test invalid mounts, which allows the test case to pass with the following output: # Starting 1 tests from 1 test cases. # RUN mount_setattr_idmapped.idmap_mount_tree_invalid ... # OK mount_setattr_idmapped.idmap_mount_tree_invalid ok 1 mount_setattr_idmapped.idmap_mount_tree_invalid # PASSED: 1 / 1 tests passed.

Fixup small broken window panes in DAMON selftests and kunit tests. First four patches clean up DAMON debugfs interface selftests output, by fixing segmentation fault of a test program (patch 1), removing unnecessary debugging messages (patch 2), and hiding error messages from expected failures (patches 3 and 4). Following two patches fix copy-paste mistakes in DAMON Kconfig help message that copied from debugfs kunit test (patch 5) and a comment on the debugfs kunit test code (patch 6).

[PATCH net 0/3] mptcp: sched: fix some lock issues

by Matthieu Baerts (NGI0)

Two small fixes related to the MPTCP packets scheduler: - Patch 1: add missing rcu_read_(un)lock(). A fix for >= 6.6. - Patch 2: remove unneeded lock when listing packets schedulers. A fix for >= 6.10. And some modifications in the MPTCP selftests: - Patch 3: a small addition to the MPTCP selftests to cover more code.
