Noteworthy changes in strace 5.15 (2021-12-01)
==============================================
* Improvements
* Implemented --strings-in-hex=non-ascii-chars option for using hexadecimal
numbers instead of octal ones in escape sequences in the output strings.
* Implemented --decode-pids=comm option (and its alias -Y) for printing
command names for PIDs.
* Implemented --decode-pids=pidns as an alias to --pidns-translation option.
* Implemented printing of current working directory when AT_FDCWD constant
is used with --decode-fds=path option enabled.
* Improved printing of syscall names in places where the associated
AUDIT_ARCH_* value is present (ptrace PTRACE_GET_SYSCALL_INFO request,
SIGSYS siginfo_t).
* Implemented decoding of process_mrelease syscall, introduced in Linux 5.15.
* Implemented decoding of SECCOMP_GET_NOTIF_SIZES operation of seccomp
syscall.
* Implemented decoding of HDIO_*, KD*, and SECCOMP_* ioctl commands.
* Implemented decoding of RTM_NEWCACHEREPORT, RTM_{NEW,DEL,GET}NEXTHOP,
and RTM_{NEW,GET}STATS NETLINK_ROUTE netlink messages.
* Implemented decoding of AF_ALG, AF_IEEE802154, AF_MCTP, AF_NFC, AF_QIPCRTR,
AF_RRPC, AF_VSOCK, and AF_XDP socket addresses.
* Implemented decoding of AF_BRIDGE and AF_MCTP protocols for IFLA_AF_SPEC
netlink attribute.
* Implemented decoding of IFLA_BR_MCAST_QUERIER_STATE, IFLA_BR_MULTI_BOOLOPT,
IFLA_INET6_RA_MTU, IFLA_INFO_SLAVE_DATA, and IFLA_VFINFO_LIST netlink
attributes.
* Enhanced decoding of io_uring_register and times syscalls.
* Enhanced IFLA_BR_FORWARD_DELAY, IFLA_BR_MAX_AGE, IFLA_EXT_MASK,
IFLA_PROTINFO, *_INTVL, and *_TIMER netlink attribute decoding.
* Enhanced decoding of AF_IPX and AF_NETLINK socket addresses.
* Updated lists o AF_*, ARPHRD_*, BTRFS_*, DEVCONF_*, DM_*, ETH_P_*,
FAN_REPORT_*, IORING_*, MOVE_MOUNT_*, MPOL_*, PACKET_*, RTM_*, SO_*,
and XFRM_MSG_* constants.
* Updated lists of ioctl commands from Linux 5.15.
* Bug fixes
* Fixed printing of struct bpf_prog_info.map_ids array.
* Fixed behaviour of "dev", "pidfd", and "socket" arguments of the --print-fds
option to no longer imply the "path" argument.
* Fixed insufficient buffer size used for network interface name printing,
that previously led to assertions on attempts of printing interface names
that require quoting, for example, names longer than 4 characters in -xx
mode (addresses RHBZ bug #2028146).
