Noteworthy changes in release 4.19 (2017-09-05)

* Changes in behaviour
  * Changed formatting of personality names on tile architecture in order
    to make it in line with other multi-personality architectures.
  * Changed field output order in struct v4l2_requestbuffers to improve in/out
    field formatting.
  * Changed handling of multiple signal= specifications in an injection
    expression: multiple specification now leads to error instead of implicit
    usage the last specification.

* Improvements
  * Enhanced decoding of optlen argument of getsockopt syscall.
  * Enhanced decoding of SO_LINGER option of getsockopt and setsockopt syscalls.
  * Enhanced decoding of SO_PEERCRED option of getsockopt syscall.
  * Enhanced decoding of IP_ADD_MEMBERSHIP, IP_DROP_MEMBERSHIP,
    IPV6_ADD_MEMBERSHIP, IPV6_DROP_MEMBERSHIP, IPV6_JOIN_ANYCAST,
    IPV6_LEAVE_ANYCAST, MCAST_JOIN_GROUP, and MCAST_LEAVE_GROUP options
    of setsockopt syscall.
  * Enhanced decoding of KEYCTL_DH_COMPUTE operation of keyctl syscall
    (KDF parameters decoding).
  * Implemented decoding of KEYCTL_RESTRICT_KEYRING operation of keyctl syscall.
  * Enhanced decoding of UFFDIO_API ioctl command.
  * Enhanced decoding of BPF_PROG_LOAD, BPF_MAP_CREATE, BPF_MAP_LOOKUP_ELEM,
    and BPF_MAP_GET_NEXT_KEY commands of bpf syscall.
  * Implemented decoding of linux socket filter programs specified
    for SO_ATTACH_FILTER and SO_ATTACH_REUSEPORT_CBPF socket options.
  * Implemented decoding of inet_diag_req_v2, inet_diag_req_compat,
    packet_diag_msg, and smc_diag_msg netlink attributes of NETLINK_SOCK_DIAG.
  * Implemented NETLINK_SELINUX protocol specific decoding.
  * Implemented decoding of netlink message ack flags.
  * Implemented decoding of nlmsgerr netlink attributes.
  * Implemented basic protocol specific decoding of NETLINK_CRYPTO.
  * Implemented decoding of crypto_user_alg netlink attributes
    of NETLINK_CRYPTO.
  * Implemented basic protocol specific decoding of addr, addrlabel, dcb, link,
    mdb, neigh, neightbl, netconf, nsid, route, rule, tc, and tca messages
    of NETLINK_ROUTE.
  * Implemented decoding of NETLINK_KOBJECT_UEVENT messages.
  * Improved handling of unexpected tracees (the ones that cloned with
    CLONE_PARENT/CLONE_PTRACE or called PTRACE_TRACEME on themselves): they
    are now PTRACE_DETACH'ed instead of PTRACE_CONT'ed.
  * Updated lists of BPF_*, KEY_*, RWF_*, SCM_*, SO_*, and *_MAGIC constants.
  * Added decoding of arch_prctl syscall on x86.
  * Added decoding of seccomp, bpf, userfaultfd, membarrier, mlock2,
    copy_file_range, preadv2, pwritev2, and statx on alpha.
  * Added decoding of statx syscall on microblaze.
  * Added decoding of s390_guarded_storage syscall on s390.
  * Updated lists of ioctl commands from Linux 4.13.
  * Enhanced manual page.

* Bug fixes
  * Fixed printing of group_req structure on non-native personalities.
  * Fixed output formatting of blkpg_ioctl_arg, dm_name_list, and iocb
    structures.
  * Fixed formatting of nul-terminated strings which have kernel-imposed size
    limit.
  * Fixed printing of paths that hit PATM_MAX limit in order to match kernel's
    behaviour.
  * Fixed build warnings on Android mips64.
  * Fixed unused function "is_negated_errno" build warning when built
    with clang.
  * Fixed syscall number and arguments retrieval behaviour on sparc64 and
    mips o32 after prctl(PR_SET_DUMPABLE, 0) makes PTRACE_PEEKTEXT impossible
    to use if Linux kernel has commit v4.10-rc1~114^2~2.
  * Fixed path tracing for execveat, symlink, symlinkat, inotify_add_watch,
    and inotify_init syscalls.
  * Fixed personality switch printing on sparc64 and risc-v.
