kdump/truss: decode new _umtx_op flags

2020-12-09T03:24:09Z

In both cases, print the flag bits first followed by the command. Output now looks something like this: (ktrace) _umtx_op(0x8605f7008,0xf,0,0,0) _umtx_op(0x9fffdce8,0x80000003,0x1,0,0) (truss) _umtx_op(0x7fffffffda50,UMTX_OP_WAKE,0x1,0x0,0x0) = 0 (0x0) _umtx_op(0x9fffdd08,UMTX_OP__32BIT|UMTX_OP_WAKE,0x1,0x0,0x0) = 0 (0x0) Reviewed by: kib Differential Revision: https://reviews.freebsd.org/D27325

kdump: decode shm_open2

2020-02-19T14:55:59Z

This is the kdump counterpart of the truss support added in r358116, and also a part of D23733. shm_open2 is the successor to shm_open. Reviewed by: kaktus

kdump: decode SHM_ANON as first arg to legacy shm_open(2)

2020-02-19T14:32:55Z

The first argument to shm_open(2) as well as shm_open2(2) may be a path or SHM_ANON. Decode SHM_ANON, at least- paths will show up as namei results in kdump output, which may be sufficient; in those cases, we'll have printed an address. Future commits will add support for shm_open2() to libsysdecode/truss/kdump. Reported by: kaktus MFC after: 3 days

Leaf directories that have dependencies impacted by options need a Makefile.depend.options file to avoid churn in Makefile.depend DIRDEPS for cases such as OPENSSL, TCP_WRAPPERS etc can be set in local.dirdeps-options.mk which can add to those set in Makefile.depend.options See share/mk/dirdeps-options.mk Reviewed by: bdrewery MFC after: 1 week Sponsored by: Juniper Networks Differential Revision: https://reviews.freebsd.org/D22469

This also implements it, fixes kdump, and removes no longer needed bits from lib/libc/sys/shm_open.c for the interim.

kdump: expand comment on reasons for CAPFAIL_LOOKUP

2019-02-18T03:49:16Z

Comment for CAPFAIL_LOOKUP refered only to paths containing ".." but it is returned for other restricted VFS lookup cases, such as absolute paths or openat(AT_FDCWD, ...).

Use 'bool' instead of 'int' for various boolean flags.

Remove spurious ABI tags from kdump output.

2018-08-07T00:10:58Z

The abidump routine output an ABI tag when -A was specified for records that were not displayed due to type or pid filtering. To fix, split the code to lookup the ABI from the code to display the ABI, move the code to display the ABI into dumpheader(), and move dumpheader() later in the main loop as a simplification. Previously dumpheader() was called under a condition that repeated conditions made later in the main loop.
