Fix linking /rescue/rescue to multiple programs in usr.bin after r315113 I meant for the line that conditionally added in /usr/bin/nc support to be `+=', not `=`. This restores hardlinks for all programs in usr.bin specified before nc(1), e.g., bunzip2 and tar. Pointyhat to: ngie

Conditionally compile [additional] programs into rescue(8) if requested Trivial oversight missed in r314240 cleanup because I enable these knobs on my test machines. MK_INET6_SUPPORT - rtsol MK_NETCAT - nc

Add shutdown/poweroff support to rescue(8) shutdown is a safer way to power off than reboot (in general), because of the added shutdown process that it executes via /etc/rc.shutdown . It was odd that it was missing from rescue(8) since reboot and friends were added in past commits. While here, alias poweroff to shutdown for parity with sbin/shutdown/Makefile

Add support to libkvm for reading vmcores from other architectures.

2015-11-27T18:58:26Z

- Add a kvaddr_type to represent kernel virtual addresses instead of unsigned long. - Add a struct kvm_nlist which is a stripped down version of struct nlist that uses kvaddr_t for n_value. - Add a kvm_native() routine that returns true if an open kvm descriptor is for a native kernel and memory image. - Add a kvm_open2() function similar to kvm_openfiles(). It drops the unused 'swapfile' argument and adds a new function pointer argument for a symbol resolving function. Native kernels still use _fdnlist() from libc to resolve symbols if a resolver function is not supplied, but cross kernels require a resolver. - Add a kvm_nlist2() function similar to kvm_nlist() except that it uses struct kvm_nlist instead of struct nlist. - Add a kvm_read2() function similar to kvm_read() except that it uses kvaddr_t instead of unsigned long for the kernel virtual address. - Add a new kvm_arch switch of routines needed by a vmcore backend. Each backend is responsible for implementing kvm_read2() for a given vmcore format. - Use libelf to read headers from ELF kernels and cores (except for powerpc cores). - Add internal helper routines for the common page offset hash table used by the minidump backends. - Port all of the existing kvm backends to implement a kvm_arch switch and to be cross-friendly by using private constants instead of ones that vary by platform (e.g. PAGE_SIZE). Static assertions are present when a given backend is compiled natively to ensure the private constants match the real ones. - Enable all of the existing vmcore backends on all platforms. This means that libkvm on any platform should be able to perform KVA translation and read data from a vmcore of any platform. Tested on: amd64, i386, sparc64 (marius) Differential Revision: https://reviews.freebsd.org/D3341
