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.
