[BUGFIX PATCH v2 0/5] selftests: Fixes for 32bit arch

by Masami Hiramatsu

Hi, Here are the 2nd version of kselftest fixes some on 32bit arch (e.g. arm). In this version, I updated [1/5] to make va_max 1GB instead of 3GB, according to Alexey's comment. When I built the ksefltest on arm, I hit some 32bit related warnings. Here are the patches to fix those issues. - [1/5] va_max was set 2^32 even on 32bit arch. This can make va_max == 0 and always fail. Make it 3GB on 32bit. - [2/5] Some VM tests requires 64bit user space, which should not run on 32bit arch. - [3/5] For counting the size of large file, we should use size_t instead of unsinged long. - [4/5] Gcc warns printf format for size_t and int64_t on 32bit arch. Use %llu and cast it. - [5/5] Gcc warns __u64 and pointer type castings. It should once translated to unsigned long. Thank you, --- Masami Hiramatsu (5): selftests: proc: Make va_max 1GB on 32bit arch selftests: vm: Build/Run 64bit tests only on 64bit arch selftests: net: Use size_t and ssize_t for counting file size selftests: net: Fix printf format warnings on arm selftests: sync: Fix cast warnings on arm tools/testing/selftests/net/so_txtime.c | 4 ++-- tools/testing/selftests/net/tcp_mmap.c | 8 ++++---- tools/testing/selftests/net/udpgso.c | 3 ++- tools/testing/selftests/net/udpgso_bench_tx.c | 3 ++- .../selftests/proc/proc-self-map-files-002.c | 11 ++++++++++- tools/testing/selftests/sync/sync.c | 6 +++--- tools/testing/selftests/vm/Makefile | 5 +++++ tools/testing/selftests/vm/run_vmtests | 10 ++++++++++ 8 files changed, 38 insertions(+), 12 deletions(-) -- Masami Hiramatsu (Linaro) <mhiramat(a)kernel.org>

[PATCH 0/1] mm/gup_benchmark: fix MAP_HUGETLB case

by John Hubbard

Hi, Here's another gup_benchmark.c fix, which I ran into while adding support for the upcoming FOLL_PIN work. Anyway, the problem is clearly described in the patch commit description, and the fix seems like the best way to me, but the fix is not *completely* black and white. This fix forces MAP_ANONYMOUS for the MAP_HUGETLB case. However, another way to do it might be to mmap() against a valid hugetlb page file, instead of /dev/zero. But that seems like a lot of trouble and if I'm reading the intent correctly, MAP_ANONYMOUS is what's desired anyway.

[PATCH][v3] kselftest: Fix NULL INSTALL_PATH for TARGETS runlist

by Prabhakar Kushwaha

As per commit 131b30c94fbc ("kselftest: exclude failed TARGETS from runlist") failed targets were excluded from the runlist. But value $$INSTALL_PATH is always NULL. It should be $INSTALL_PATH instead $$INSTALL_PATH. So, fix Makefile to use $INSTALL_PATH.

[PATCH] kselftest: Fix NULL INSTALL_PATH for TARGETS runlist

by Prabhakar Kushwaha

As per commit 131b30c94fbc ("kselftest: exclude failed TARGETS from runlist") failed targets were excluded from the runlist. But value $$INSTALL_PATH is always NULL. It should be $INSTALL_PATH instead $$INSTALL_PATH. So, fix Makefile to use $INSTALL_PATH.

[PATCH 2/2][SRU][DISCO][EOAN] UBUNTU: SAUCE: seccomp: fix SECCOMP_USER_NOTIF_FLAG_CONTINUE test

by Christian Brauner

BugLink: https://bugs.launchpad.net/bugs/1849281 The ifndef for SECCOMP_USER_NOTIF_FLAG_CONTINUE was placed under the ifndef for the SECCOMP_FILTER_FLAG_NEW_LISTENER feature. This will not work on systems that do support SECCOMP_FILTER_FLAG_NEW_LISTENER but do not support SECCOMP_USER_NOTIF_FLAG_CONTINUE. So move the latter ifndef out of the former ifndef's scope. 2019-10-20 11:14:01 make run_tests -C seccomp make: Entering directory '/usr/src/perf_selftests-x86_64-rhel-7.6-0eebfed2954f152259cae0ad57b91d3ea92968e8/tools/testing/selftests/seccomp' gcc -Wl,-no-as-needed -Wall seccomp_bpf.c -lpthread -o seccomp_bpf seccomp_bpf.c: In function ‘user_notification_continue’: seccomp_bpf.c:3562:15: error: ‘SECCOMP_USER_NOTIF_FLAG_CONTINUE’ undeclared (first use in this function) resp.flags = SECCOMP_USER_NOTIF_FLAG_CONTINUE; ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ seccomp_bpf.c:3562:15: note: each undeclared identifier is reported only once for each function it appears in Makefile:12: recipe for target 'seccomp_bpf' failed make: *** [seccomp_bpf] Error 1 make: Leaving directory '/usr/src/perf_selftests-x86_64-rhel-7.6-0eebfed2954f152259cae0ad57b91d3ea92968e8/tools/testing/selftests/seccomp' Reported-by: kernel test robot <rong.a.chen(a)intel.com> Fixes: 0eebfed2954f ("seccomp: test SECCOMP_USER_NOTIF_FLAG_CONTINUE") Cc: linux-kselftest(a)vger.kernel.org Signed-off-by: Christian Brauner <christian.brauner(a)ubuntu.com> Reviewed-by: Tycho Andersen <tycho(a)tycho.ws> Link: https://lore.kernel.org/r/20191021091055.4644-1-christian.brauner@ubuntu.com Signed-off-by: Kees Cook <keescook(a)chromium.org> (cherry picked from commit 2aa8d8d04ca29c3269154e1d48855e498be8882f https://git.kernel.org/pub/scm/linux/kernel/git/kees/linux.git) Signed-off-by: Christian Brauner <christian.brauner(a)ubuntu.com> --- tools/testing/selftests/seccomp/seccomp_bpf.c | 8 ++++---- 1 file changed, 4 insertions(+), 4 deletions(-) diff --git a/tools/testing/selftests/seccomp/seccomp_bpf.c b/tools/testing/selftests/seccomp/seccomp_bpf.c index 6021baecb386..bf834ee02b69 100644 --- a/tools/testing/selftests/seccomp/seccomp_bpf.c +++ b/tools/testing/selftests/seccomp/seccomp_bpf.c @@ -167,10 +167,6 @@ struct seccomp_metadata { #define SECCOMP_RET_USER_NOTIF 0x7fc00000U -#ifndef SECCOMP_USER_NOTIF_FLAG_CONTINUE -#define SECCOMP_USER_NOTIF_FLAG_CONTINUE 0x00000001 -#endif - #define SECCOMP_IOC_MAGIC '!' #define SECCOMP_IO(nr) _IO(SECCOMP_IOC_MAGIC, nr) #define SECCOMP_IOR(nr, type) _IOR(SECCOMP_IOC_MAGIC, nr, type) @@ -209,6 +205,10 @@ struct seccomp_notif_sizes { #define PTRACE_EVENTMSG_SYSCALL_EXIT 2 #endif +#ifndef SECCOMP_USER_NOTIF_FLAG_CONTINUE +#define SECCOMP_USER_NOTIF_FLAG_CONTINUE 0x00000001 +#endif + #ifndef seccomp int seccomp(unsigned int op, unsigned int flags, void *args) { -- 2.23.0

[PATCH v3 1/2] clone3: add CLONE_CLEAR_SIGHAND

by Christian Brauner

Reset all signal handlers of the child not set to SIG_IGN to SIG_DFL. Mutually exclusive with CLONE_SIGHAND to not disturb other thread's signal handler. In the spirit of closer cooperation between glibc developers and kernel developers (cf. [2]) this patchset came out of a discussion on the glibc mailing list for improving posix_spawn() (cf. [1], [3], [4]). Kernel support for this feature has been explicitly requested by glibc and I see no reason not to help them with this. The child helper process on Linux posix_spawn must ensure that no signal handlers are enabled, so the signal disposition must be either SIG_DFL or SIG_IGN. However, it requires a sigprocmask to obtain the current signal mask and at least _NSIG sigaction calls to reset the signal handlers for each posix_spawn call or complex state tracking that might lead to data corruption in glibc. Adding this flags lets glibc avoid these problems. [1]: https://www.sourceware.org/ml/libc-alpha/2019-10/msg00149.html [3]: https://www.sourceware.org/ml/libc-alpha/2019-10/msg00158.html [4]: https://www.sourceware.org/ml/libc-alpha/2019-10/msg00160.html [2]: https://lwn.net/Articles/799331/ '[...] by asking for better cooperation with the C-library projects in general. They should be copied on patches containing ABI changes, for example. I noted that there are often times where C-library developers wish the kernel community had done things differently; how could those be avoided in the future? Members of the audience suggested that more glibc developers should perhaps join the linux-api list. The other suggestion was to "copy Florian on everything".'
