libsysdecode: decode _UMTX_OP flags

2020-12-09T03:22:44Z

Assume that UMTX_OP with a double underbar following is a flag, while any underbar+alphanumeric combination immeiately following is an op. This was a part of D27325. Reviewed by: kib

Add MSG_TLSAPPDATA to lib/libsysdecode/mktables.

I have no idea what this does (and until now that it even existed), but apparently it needs this entry changed for the MSG_TLSAPPDATA, since it is kernel only.

libsysdecode: grab shmflags from sys/mman.h, add decode method

2020-02-19T14:52:32Z

Any SHM_* flag here is (and likely will continue to be) a shmflag that may be passed to shm_open2(), with exception to SHM_ANON. This is a prereq to adding appropriate support to truss/kdump. Reviewed by: kaktus (slightly earlier version) Differential Revision: https://reviews.freebsd.org/D23733

Avoid touching the tables.h file unless it has changed to avoid unneeded rebuilds. Also revert r350301's explicit dependencies. Reviewed by: emaste MFC after: 2 weeks X-MFC-With: r339635 (kevans request) PR: 238828 Sponsored by: DellEMC Differential Revision: https://reviews.freebsd.org/D21295

Fix regex for extracting SHM_* values for libsysdecode

2018-10-23T06:31:19Z

There was an additional + after the {6} which is apparently ignored by the FreeBSD regex implementation but was giving me an error when compiling on MacOS. While changing this also make sure that tables.h is not created if mktables fails. The current rule would create a partial tables.h which causes following incremental builds to use that broken file and fail with an unrelated compilation error or even succeed even though they shouldn't.

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().
