(????-??-??) +Noteworthy changes in release 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 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. + Noteworthy changes in release 4.10 (2015-03-06) =============================================== -- 2.40.0
