* Use MACHINE_CPUARCH when checking for arm64Andrew Turner2020-09-141-1/+1
| | | | | | | | | | | | | | | Use MACHINE_CPUARCH with arm64 (aarch64) when we build code that could run on any 64-bit Arm instruction set. This will simplify checks in downstream consumers targeting prototype instruction sets. The only place we check for MACHINE_ARCH == aarch64 is when building the device tree blobs. As these are targeting current generation ISAs. Sponsored by: Innovate UK Differential Revision: https://reviews.freebsd.org/D26370 Notes: svn path=/head/; revision=365726

* various: general adoption of SPDX licensing ID tags.Pedro F. Giffuni2017-11-271-0/+2
| | | | | | | | | | | | | | | | | Mainly focus on files that use BSD 2-Clause license, however the tool I was using misidentified many licenses so this was mostly a manual - error prone - task. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts. No functional change intended.

| | | | | | | | | | | | | | | | In the kernel, cache the machine and flags fields from ELF header to use in the ELF header of a core dump. For gcore, the copy these fields over from the ELF header in the binary. This matters for platforms which encode ABI information in the flags field (such as o32 vs n32 on MIPS).

* Include process IDs in core dumps.John Baldwin2016-07-181-0/+1
| | | | | | | | | | | | | | | | When threads were added to the kernel, the pr_pid member of the NT_PRSTATUS note was repurposed to store LWP IDs instead of process IDs. However, the process ID was no longer recorded in core dumps. This change adds a pr_pid field to prpsinfo (NT_PRSINFO). Rather than bumping the prpsinfo version number, note parsers can use the note's payload size to determine if pr_pid is present.

| | | | | | | | | | | | | | | | Use size of destination buffer, rather than a constant that may or may not correspond to the source buffer, to restrict the length of copied strings. In particular, pr_fname has 16+1 characters but MAXCOMLEN is 18+1. Use strlcpy instead of strncpy to ensure the result is nul-terminated. This seems to be what is expected of these fields.

This avoids having to always make two ptrace() calls to get or set the full XSAVE state. - Add a PT_GET_XSTATE_INFO which returns the length of the current XSTATE save area (so the size of the buffer needed for PT_GETXSTATE) and the current XSAVE mask (%xcr0).

In order to do that, and in order to avoid KBI breakage with existing infrastructure the following semantic is implemented: - For live programs, a new member to the PT_LWPINFO is added (pl_tdname) - For cores, a new ELF note is added (NT_THRMISC) that can be used for storing thread specific, miscellaneous, informations. Right now it is just popluated with a thread name. GDB, then, retrieves the correct informations from the corefile via the BFD interface, as it groks the ELF notes and create appropriate pseudo-sections.
