NEWS for strace version 4.11 ============================ * Changes in behavior * Some syscalls have different names depending on architecture and personality. In these cases, syscall filtering and printing now consistently uses the names that match corresponding __NR_* kernel macros of the tracee's architecture and personality. * Added strace prefix to all diagnostic messages. * Improvements * Enhanced and extended test suite. * Implemented reliable tracing of processes whose personality differs from the personality of strace, fixed decoding of 32-bit personality syscalls on 64-bit architectures. * When some data referenced by syscall arguments is irrelevant or cannot be read from tracee's memory, strace now prints its address consistently. * When a syscall is restarted using restart_syscall mechanism, strace now shows the syscall name on architectures that expose this information. * Print values returned by epoll_create1, eventfd, eventfd2, fanotify_init, inotify_init1, perf_event_open, pipe, pipe2, signalfd, signalfd4, socket, socketpair, timerfd, and timerfd_create syscalls, as well as F_DUPFD and F_DUPFD_CLOEXEC fcntl commands, as file descriptors. * Optimized decoding of indirect socket syscalls. * Implemented decoding of nanoseconds along with seconds in stat family syscalls (addresses Fedora bug #1251176). * Implemented decoding of struct statfs.f_flags in statfs syscall. * Implemented decoding of siginfo_t.si_syscall and siginfo_t.si_arch in SIGSYS signal. * Implemented decoding of indirect syscall on mips o32. * Implemented decoding of IPPROTO_IP control messages. * Implemented decoding of setsockopt syscall multicast arguments. * Enhanced decoding of struct sigevent. * Enhanced decoding of block, loop, mtd, ptp, rtc, SG_IO, socket, tty, and v4l2 ioctl syscall arguments. * Enhanced decoding of epoll_create, fcntl, fcntl64, futex, getdents, getdents64, getsockopt, io_*, mount, msgctl, prctl, quotactl, recvfrom, sendfile, setsockopt, and shmctl syscalls. * Implemented decoding of bpf, execveat, ioperm, iopl, kcmp, kexec_file_load, lookup_dcookie, membarrier, memfd_create, mlock2, name_to_handle_at, open_by_handle_at, sched_getattr, sched_setattr, and userfaultfd syscalls. * Updated lists of AF_*, EPOLL_*, FALLOC_FL_*, F_*, INPUT_PROP_*, IPPROTO_*, IPV6_*, IP_*, KEY_*, LOCK_*, MNT_*, MS_*, PACKET_*, PERF_FLAG_*, PF_*, PR_*, PTRACE_O_*, RENAME_*, SCTP_*, SECBIT_*, SO_*, TCP_*, and siginfo_t constants. * Added Nios II architecture support. * Added new syscall entries to match Linux 4.4. * Bug fixes * Fixed potential short read of strings from tracee's memory. * Fixed -qq option in conjunction with -o option. * Fixed filtering of <unavailable> syscalls. * Fixed decoding of ioctl syscall command on aarch64 and 32-bit architectures with 64-bit aligned structures. * Fixed decoding of eventfd2, epoll_create1, signalfd4, and sync_file_range2 syscall flags arguments. * Fixed decoding of 4th argument of clock_nanosleep syscall. * Fixed decoding of getpagesize syscall on m68k. * Fixed decoding of getrandom and seccomp syscalls on aarch64. * Fixed decoding of timezone argument of gettimeofday and settimeofday * syscalls. * Fixed decoding of offset argument of mmap2 syscall on arm, sparc, and sparc64. * Fixed decoding of pipe syscall on alpha and mips. * Fixed decoding of pipe2 syscall on ia64, sh, sparc, and sparc64. * Fixed decoding of signal mask argument of pselect6 syscall on x32. * Fixed decoding of signal mask of rt_sigreturn syscall on aarch64, m68k, and x32. * Fixed decoding of 4th argument of semctl indirect syscall. * Fixed decoding of sa_restorer and sa_mask of sigaction syscall on m68k. * Fixed decoding of statfs64 and fstatfs64 syscalls on arm eabi. * Fixed decoding of struct dirent on x32. * Fixed decoding of times syscall return value on mips n32 and x32. * Fixed decoding of path argument of umount2 syscall (addresses Debian bug #785050). * Worked around a kernel bug in tracing privileged executables. * Fixed various errors in mapping between syscall numbers and associated information like the number of syscall arguments, the name of syscall, and syscall decoder.
