sysdecode: Add aarch64

2023-04-12T04:14:17Z

FREEBSD32 API is also supported on aarch64. Refer to aarch64 instead of arm64 because it's about the architecture (powerpc64), not the kernel interface... Sponsored by: Netflix

libsysdecode: Include required headers in sysdecode.h

2022-04-15T14:22:29Z

Make sysdecode.h self-contained rather than forcing all consumers to include dependencies. No functional change intended. Reviewed by: pauamma_gundo.com, jhb, emaste MFC after: 2 weeks Sponsored by: The FreeBSD Foundation Differential Revision: https://reviews.freebsd.org/D34899

libsysdecode: Add a new ABI type, SYSDECODE_ABI_CLOUDABI32.

2017-12-16T19:37:55Z

In order to let truss(8) support tracing of 32-bit CloudABI applications, we need to add a new ABI type to libsysdecode. We can reuse the existing errno mapping table. Also link in the cloudabi32 system call table to translate system call names. While there, remove all of the architecture ifdefs. There are not needed, as the CloudABI data types and system call tables build fine on any architecture. Building this unconditionally will make it easier to do tracing for different compat modes, emulation, etc. Reviewed by: jhb Differential Revision: https://reviews.freebsd.org/D13516

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().
