strace cann't trace time() system call on x86_64

Version:strace-4.14, strace-4.13, strace-4.5.20 Environment: ubuntu 16.04.1 LTS x86_64 I use strace to trace a program with time() system call, but it not print time() system call. I also do the same test on ubuntu 14.04 LTS i386, it can trace time() system call. I can find the time() system in

[PATCH 00/15] Various misc tests

Hello. This patchset adds tests for inotify_add_watch, inotify_init1, inotify_rm_watch, ioprio_get, ioprio_set, kcmp, lookup_dcookie, process_vm_readv, process_vm_writev syscalls. Eugene Syromyatnikov (15): tests: iporio_get/ioprio_set test added tests: Move LL_PAIR and LL_VAL_TO_PAIR macros

[PATCH 08/15] process_vm: Print pid argument as int

[PATCH 09/15] v4l2: check for verbose flag in umoven_or_printaddr_ignore_syserror

This change makes behaviour of umoven_or_printaddr_ignore_syserror in line with umoven_or_printaddr when verbose flag is disabled. * v4l2.c (umoven_or_printaddr_ignore_syserror): Simply call printaddr when verbose flag is unset. --- v4l2.c |2 +- 1 file changed, 1 insertion(+), 1 deletion(-)

[PATCH 12/15] tests: Update preadv test in order to reflect changed behaviour

Since iovecs themselves are printed evan syscall has failed now, test is updated to reflect this. It is notable, though, that this is the only place where this case is checked. * tests/preadv.c: Update output for the case when preadv with singe-item iovec failed. --- tests/preadv.c |3 ++- 1

[PATCH 14/15] process_vm: Remove syserror check for iovec printing

This check had been done by print_array inside tprint_iov anyway. * process_vm.c (SYS_FUNC(process_vm_readv)): Use tprint_iov_upto for printing local_iov; do not check for syserror, provide decode_iov parameter to tprint_iov{,_upto} based on its value instead. --- process_vm.c | 17 +---

[PATCH 11/15] io: Use umoven_or_printaddr_ignore_syserror as umove function in tprint_iov_upto

This enables printing of iovec arrays even in case of failed syscall (failed syscall doesn't mean that iovec itself is inaccessible and useless). One caveat here is that we should explicitly provide proper IOV_DECODE_* value based on syserror value in case printing is performed on exiting; we can't
