* Do a sweep and remove most WARNS=6 settingsKyle Evans2020-10-011-2/+0
| | | | | | | | | | | | | | | 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_kerndispLeandro Lupori2020-02-061-2/+2
| | | | | | | | | | | | | | | 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 Notes: svn path=/head/; revision=357615

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.

* Add support to libkvm for reading vmcores from other architectures.John Baldwin2015-11-271-28/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - 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.

* Add a new ARM TARGET_ARCH, armv6hf. This is considered experimental.Andrew Turner2014-03-231-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This targets the existing ARMv6 and ARMv7 SoCs that contain a VFP unit. This is an optional coprocessors may not be present in all devices, however it appears to be in all current SoCs we support. armv6hf targets the VFP variant of the ARM EABI and our copy of gcc is too old to support this. Because of this there are a number of WITH/WITHOUT options that are unsupported and must be left as the default value. The options and their required value are: * WITH_ARM_EABI * WITHOUT_GCC * WITHOUT_GNUCXX In addition, without an external toolchain, the following need to be left as their default: * WITH_CLANG * WITH_CLANG_IS_CC As there is a different method of passing float and double values to functions the ABI is incompatible with existing armv6 binaries. To use this a full rebuild of world is required. Because no floating point values are passed into the kernel an armv6 kernel with VFP enabled will work with an armv6hf userland and vice versa.

| | | | | | | | | | | | | | | one significant difference: for LIB32 builds both TARGET_ARCH and MACHINE_ARCH are defined. TARGET_ARCH confusingly holds the architecture of the host (e.g. amd64), while MACHINE_ARCH holds the architecture were trying to build (e.g. i386). With both set and different, r260022 changed the behaviour to interpret the condition as building a cross-amd64 libkvm on i386, when obviously we're trying to build an i386 version on amd64. When COMPAT_32BIT is defined, we're building LIB32 and ignore the value of TARGET_ARCH as we did before. Notes: svn path=/head/; revision=260599

For symbol lookups, use ps_pglobal_lookup() instead of __fdnlist() when building a cross libkvm.

* libkvm: fix process runtime calculation on crashdumpsUlrich Spörlein2011-01-231-1/+1
| | | | | | | | | | | | | | | | Fix a long standing bug, where the procs ticks where assumed to be in us. Instead, read cpu_tick_frequency from the kernel and use the same logic to convert runtime. This is still too optimistic in that it assumes cpu_tick_frequency is available and fixed. Since this function is only called on crashdumps, I think we can live with that. Testing has shown the values to be correct for different kern.hz inside Virtualbox. Bump WARNS. Alignment issues on some archs mean this is still at 3.

Calls to kvm_nlist(3) will automatically translate DPCPU symbols and return a pointer to the current CPU's version of the data. Consumers needing to read the same symbol on several CPUs will invoke a series of setcpu/nlist calls, one per CPU of interest. This addition makes it possible for tools like netstat(1) to query the values of DPCPU variables during crashdump analysis, and is based on similar code handling virtualized global variables.

If we cannot resolve a symbol try to see if we can find it with prefix of the virtualized subsystem, currently only "vnet_entry" by identifying either the vnet of the current process for a live system or the vnet of proc0 (or of dumptid if compiled in a non-default way). The way this is done currently allows us to only touch libkvm but no single application. Once we are going to virtualize more subsystems we will have to review this decision for better scaling.
