Move mksubr from kdump into libsysdecode. 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.

Decode kevent structures logged via ktrace(2) in kdump. - Add a new KTR_STRUCT_ARRAY ktrace record type which dumps an array of structures. The structure name in the record payload is preceded by a size_t containing the size of the individual structures. Use this to replace the previous code that dumped the kevent arrays dumped for kevent(). kdump is now able to decode the kevent structures rather than dumping their contents via a hexdump. One change from before is that the 'changes' and 'events' arrays are not marked with separate 'read' and 'write' annotations in kdump output. Instead, the first array is the 'changes' array, and the second array (only present if kevent doesn't fail with an error) is the 'events' array. For kevent(), empty arrays are denoted by an entry with an array containing zero entries rather than no record. - Move kevent decoding tables from truss to libsysdecode. This adds three new functions to decode members of struct kevent: sysdecode_kevent_filter, sysdecode_kevent_flags, and sysdecode_kevent_fflags. kdump uses these helper functions to pretty-print kevent fields. - Move structure definitions for freebsd11 and freebsd32 kevent structures to <sys/event.h> so that they can be shared with userland. The 32-bit structures are only exposed if _WANT_KEVENT32 is defined. The freebsd11 structures are only exposed if _WANT_FREEBSD11_KEVENT is defined. The 32-bit freebsd11 structure requires both. - Decode freebsd11 kevent structures in truss for the compat11.kevent() system call. - Log 32-bit kevent structures via ktrace for 32-bit compat kevent() system calls. - While here, constify the 'void *data' argument to ktrstruct().

Move mksubr from kdump into libsysdecode. 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.

Decode kevent structures logged via ktrace(2) in kdump. - Add a new KTR_STRUCT_ARRAY ktrace record type which dumps an array of structures. The structure name in the record payload is preceded by a size_t containing the size of the individual structures. Use this to replace the previous code that dumped the kevent arrays dumped for kevent(). kdump is now able to decode the kevent structures rather than dumping their contents via a hexdump. One change from before is that the 'changes' and 'events' arrays are not marked with separate 'read' and 'write' annotations in kdump output. Instead, the first array is the 'changes' array, and the second array (only present if kevent doesn't fail with an error) is the 'events' array. For kevent(), empty arrays are denoted by an entry with an array containing zero entries rather than no record. - Move kevent decoding tables from truss to libsysdecode. This adds three new functions to decode members of struct kevent: sysdecode_kevent_filter, sysdecode_kevent_flags, and sysdecode_kevent_fflags. kdump uses these helper functions to pretty-print kevent fields. - Move structure definitions for freebsd11 and freebsd32 kevent structures to <sys/event.h> so that they can be shared with userland. The 32-bit structures are only exposed if _WANT_KEVENT32 is defined. The freebsd11 structures are only exposed if _WANT_FREEBSD11_KEVENT is defined. The 32-bit freebsd11 structure requires both. - Decode freebsd11 kevent structures in truss for the compat11.kevent() system call. - Log 32-bit kevent structures via ktrace for 32-bit compat kevent() system calls. - While here, constify the 'void *data' argument to ktrstruct().

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.

Move mksubr from kdump into libsysdecode. 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.
