Decode kevent structures logged via ktrace(2) in kdump.

2017-11-25T04:49:12Z

- 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 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().

Decode pathconf() names, *at() flags, and sysarch() numbers in libsysdecode.

2017-09-04T05:34:36Z

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.

Tweak r320206: Still create the TABLE but not the .depend entry for missing headers.

Follow-up r308602: Don't add missing headers to .depend.tables.h.

2017-06-21T23:01:18Z

This also avoids an error from egrep when a header is missing. This can happen with something like WITHOUT_BLUETOOTH set when searching for $include_dir/netgraph/bluetooth/include/ng_btsocket.h. The warning was not an error (from set -e) due to being on the left side of a pipe. Now the all_headers list is only filled with existing headers.

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(). PR: 215448 Submitted by: Anton Yuzhaninov MFC after: 1 month
