* Add support to libkvm for reading vmcores from other architectures.John Baldwin2015-11-273-29/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - 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 Notes: svn path=/head/; revision=291406

* Replace DPSRCS that work fine in SRCS.Bryan Drewery2015-11-251-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is so that 'make depend' is not a required build step in these files. DPSRCS is overall unneeded. DPSRCS already contains SRCS, so anything which can safely be in SRCS should be. DPSRCS is mostly just a way to generate files that should not be linked into the final PROG/LIB. For headers and grammars it is safe for them to be in SRCS since they will be excluded during linking and installation. The only remaining uses of DPSRCS are for generating .c or .o files that must be built before 'make depend' can run 'mkdep' on the SRCS c files list. A semi-proper example is in tests/sys/kern/acct/Makefile where a checked-in .c file has an #include on a generated .c file. The generated .c file should not be linked into the final PROG though since it is #include'd. The more proper way here is just to build/link it in though without DPSRCS. Another example is in sys/modules/linux/Makefile where a shell script runs to parse a DPSRCS .o file that should not be linked into the module. Beyond those, the need for DPSRCS is largely unneeded, redundant, and forces 'make depend' to be ran. Generally, these Makefiles should avoid the need for DPSRCS and define proper dependencies for their files as well. An example of an improper usage and why this matters is in usr.bin/netstat. nl_defs.h was only in DPSRCS and so was not generated during 'make all', but only during 'make depend'. The files including it lacked proper depenencies on it, which forced running 'make depend' to workaround that bug. The 'make depend' target should mostly be used for incremental build help, not to produce a working build. This specific example was broken in the meta build until r287905 since it does not run 'make depend'. The gnu/lib/libreadline/readline case is fine since bsd.lib.mk has 'OBJS: SRCS:M*.h' when there is no .depend file.

* META MODE: Prefer INSTALL=tools/install.sh to lessen the need for xinstall.host.Bryan Drewery2015-11-256-6/+0
| | | | | | | | | | | This both avoids some dependencies on xinstall.host and allows bootstrapping on older releases to work due to lack of at least 'install -l' support. Sponsored by: EMC / Isilon Storage Division Notes: svn path=/head/; revision=291307
* Fix ld not respecting --sysroot.Bryan Drewery2015-11-241-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | ld(1) uses the /usr/libdata/ldscripts when linking. These scripts add in the default search paths of /lib and /usr/lib via 'SEARCH_DIR("DIR")'. These need to be prefixed by '=' so that the --sysroot flag is respected. This is not a problem with buildworld since the TOOLS_PREFIX is baked into the cross-ld. However it is a problem when trying to use ld(1) with --sysroot anywhere else as it ends up still reading /lib and /usr/lib despite --sysroot. The default --sysroot (TARGET_SYSTEM_ROOT) is '/' for /usr/bin/ld. I found this while building with META MODE with uses only --sysroot with /usr/bin/ld, and found that libraries that I had not built in its sysroot directory were leaking in. This didn't happen with ports binutils either. This would also impact external compiler support.

* Avoid warning race with creating 'ldscripts' directory during build.Bryan Drewery2015-10-161-2/+1
| | | | | | | | | | | | | | | | In r204548 the 'rm -f ldscripts' was added likely due to reading the conditional as 'else it is a file'. That seems unlikely though and the more likely case is just that the directory hasn't been created yet. Because this races with ,ssother scripts, use 'mkdir -p' which is a minimal modification vs upstream to avoid the warning of 'File exists' if another script creates it first. This could replace the 'test -d' as well but then it's more unneeded change to the upstream script. Sponsored by: EMC / Isilon Storage Division Notes: svn path=/head/; revision=289410

* When XSAVE support was added on amd64, the FPU save area was movedJohn Baldwin2015-09-291-1/+0
| | | | | | | | | | | | | | | | | | | | | | out of 'struct pcb' and into a variable-sized region after the structure. The kgdb code currently only reads the pcb. It does not read in the FPU save area but instead passes stack garbage as the FPU's saved context. Fixing this would mean determining the proper size of the area and fetching it. However, this state is not saved for running CPUs in stoppcbs[], so the callback would also have to know to ignore those pcbs. Instead, just remove the call since it is of limited usefulness. It results in kgdb reporting the state of the FPU/SIMD registers in userland, not their current values in the kernel. In particular, it does not report the correct state for any code in the kernel which does use the FPU and would report incorrect values in that case.
