The returned integer value is output. 319520: Decode the 'who' argument passed to getrusage(). Add a new sysdecode_getrusage_who() which decodes the RUSAGE_* constant passed as the first argument to getrusage(). Use this function in both kdump and truss to decode the first argument to getrusage(). 319595: Decode arguments to dup, dup2, getdirentries, pread, and pwrite. - dup and dup2 print fd arguments in decimal. - pread and pwrite are similar to read and write with the addition of the file offset. - getdirentries displays the output entries as a string for now and also prints the value returned in *basep. Eventually the buffer for getdirentries should perhaps be decoded as an array of dirent structures. 319677: Decode arguments to ACL related system calls. This only decodes the raw arguments but not the contents of the struct acl objects. 319679: Decode arguments passed to extended attribute related system calls. The cmd argument passed to extattrctl() is not decoded as a string constant but is just printed in hex. The value is filesystem-specific but in practice is only used with UFS1 filesystems. 319680: Decode arguments to minherit(). 319681: Decode arguments to mlock(), mlockall(), and munlock(). 319688: Decode flags passed to mount(), nmount(), and unmount(). 319689: Decode arguments passed to msync(). 319761: Fix decoding of setpriority() arguments. The PRIO_* 'which' value is stored in the first argument to setpriority(2), not the last. While here, decode the arguments to getpriority(2). 319762: Decode arguments to getpriority() and setpriority(). 319763: Decode the arguments to ptrace(). This does not decode structures returned by ptrace(). 319764: Decode the arguments to quotactl(). 319765: Improve decoding of RB_AUTOBOOT in the 'howto' argument to reboot(). The reboot() system call accepts a mode (RB_AUTOBOOT, RB_HALT, RB_POWEROFF, or RB_REROOT) as well as zero or more optional flags in 'howto'. However, RB_AUTOBOOT was only displayed if 'howto' was exactly 0. Combinations like 'RB_AUTOBOOT | RB_DUMP' were decoded as 'RB_DUMP'. Instead, imply that RB_AUTOBOOT was specified if none of the other "mode" flags were specified. 319766: Decode the 'howto' argument to reboot(). 319767: Decode arguments to rtprio_thread() (same as rtprio()). 319768: Decode arguments to rtprio() and rtprio_thread(). 320010: Decode arguments to sched_* family of system calls. This includes decoding both scheduler policy constants and the sched_param structure for sched_get_priority_max(), sched_get_priority_min(), sched_getparam(), sched_getscheduler(), sched_rr_get_interval(), sched_setparam(), and sched_setscheduler(). 322899: Decode arguments passed to thr_set_name(). 322959: Decode extra signal information for caught signals. Decode fields from the siginfo_t stored in the PT_LWPINFO structure when a signal is caught by a traced process. This includes the signal code (si_code) as well as additional members such as si_addr, si_pid, etc. 323020: Trim stale prototype for ioctlname(). 323021: Decode signal information returned by system calls. Specifically, decode the siginfo structure returned by sigtimedwait(), sigwaitinfo(), and wait6(). While here, also decode the signal number returned in the second argument to sigwait(). 323151: Decode pathconf() names, *at() flags, and sysarch() numbers in libsysdecode. Move tables that were previously in truss over to libsysdecode. truss output is unchanged, but kdump has been updated to decode these fields. In addition, sysdecode_sysarch_number() should support all platforms whereas the old table in truss only supported x86.

Restructure this script so that it generates a header of tables instead of a source file. The tables are included in a flags.c source file which provides functions to decode various system call arguments. For functions that decode an enumeration, the function returns a pointer to a string for known values and NULL for unknown values. For functions that do more complex decoding (typically of a bitmask), the function accepts a pointer to a FILE object (open_memstream() can be used as a string builder) to which decoded values are written. If the function operates on a bitmask, the function returns true if any bits were decoded or false if the entire value was valid. Additionally, the third argument accepts a pointer to a value to which any undecoded bits are stored. This pointer can be NULL if the caller doesn't care about remaining bits. Convert kdump over to using decoder functions from libsysdecode instead of mksubr. truss also uses decoders from libsysdecode instead of private lookup tables, though lookup tables for objects not decoded by kdump remain in truss for now. Eventually most of these tables should move into libsysdecode as the automated table generation approach from mksubr is less stale than the static tables in truss. Some changes have been made to truss and kdump output: - The flags passed to open() are now properly decoded in that one of O_RDONLY, O_RDWR, O_WRONLY, or O_EXEC is always included in a decoded mask. - Optional arguments to open(), openat(), and fcntl() are only printed in kdump if they exist (e.g. the mode is only printed for open() if O_CREAT is set in the flags). - Print argument to F_GETLK/SETLK/SETLKW in kdump as a pointer, not int. - Include all procctl() commands. - Correctly decode pipe2() flags in truss by not assuming full open()-like flags with O_RDONLY, etc. - Decode file flags passed to *chflags() as file flags (UF_* and SF_*) rather than as a file mode. - Fix decoding of quotactl() commands by splitting out the two command components instead of assuming the raw command value matches the primary command component. In addition, truss and kdump now build without triggering any warnings. All of the sysdecode manpages now include the required headers in the synopsis. 307948: Use binary and (&) instead of logical to extract the mask of a capability. 308602: Generate and use a proper .depend file for tables.h. 308603: Move libsysdecode-specific hack out of buildworld. This should fix the lib32 build since it was not removing the generated ioctl.c. This file is generated by a find(1) call, so cannot use normal dependency tracking methods. 311151: Update libsysdecode for getfsstat() 'flags' argument changing to 'mode'. As a followup to r310638, update libsysdecode (and kdump) to decode the 'mode' argument to getfsstat(). sysdecode_getfsstat_flags() has been renamed to sysdecode_getfsstat_mode() and now treats the argument as an enumerated value rather than a mask of flags.
