Do a sweep and remove most WARNS=6 settings

2020-10-01T01:10:51Z

Repeating the default WARNS here makes it slightly more difficult to experiment with default WARNS changes, e.g. if we did something absolutely bananas and introduced a WARNS=7 and wanted to try lifting the default to that. Drop most of them; there is one in the blake2 kernel module, but I suspect it should be dropped -- the default WARNS in the rest of the build doesn't currently apply to kernel modules, and I haven't put too much thought into whether it makes sense to make it so.

Implement kvm_kerndisp

2020-02-06T13:21:59Z

This change adds a new libkvm function, kvm_kerndisp(), that can be used to retrieve the kernel displacement, that is the difference between the kernel's base virtual address at run time and the kernel base virtual address specified in the kernel image file. This will be used by kgdb, to properly relocate kernel symbols, when needed. Reviewed by: jhb Differential Revision: https://reviews.freebsd.org/D23285

[PPC64] Initial libkvm minidump implementation

2019-12-09T13:59:36Z

This change adds PowerPC64 support for minidumps on libkvm. Address translation, page walk, and data retrieval were tested and seem to be working correctly. Reviewed by: jhibbits Differential Revision: https://reviews.freebsd.org/D21555

pkgbase: Put a lot of binaries and lib in FreeBSD-runtime

All of them are needed to be able to boot to single user and be able to repair a existing FreeBSD installation so put them directly into FreeBSD-runtime. Reviewed by: bapt, gjb Differential Revision: https://reviews.freebsd.org/D21503

Use __SCCSID for SCCS IDs in libkvm sources.

2018-05-22T15:52:22Z

Rather than using #ifdef's around a static char array, use the existing helper macro from for SCCS IDs. To preserve existing behavior, add -DNO__SCCSID to CFLAGS to not include SCCS IDs in the built library by default.

lib/libkvm: start adding basic tests for kvm(3)

2017-03-28T17:37:49Z

- kvm_close: add a testcase to verify support for errno = EINVAL / -1 (see D10065) when kd == NULL is provided to the libcall. - kvm_geterr: -- Add a negative testcase for kd == NULL returning "" (see D10022). -- Add two positive testcases: --- test the error case using kvm_write on a O_RDONLY descriptor. --- test the "no error" case using kvm_read(3) and kvm_nlist(3) as helper routines and by injecting a bogus error message via _kvm_err (an internal API) _kvm_err was used as there isn't a formalized way to clear the error output, and because kvm_nlist always returns ENOENT with the NULL terminator today. - kvm_open, kvm_open2: -- Add some basic negative tests for kvm_open(3) and kvm_open2(3). Testing positive cases with a specific `corefile`/`execfile`/`resolver` requires more work and would require user intervention today in order to reliably test this out.
