* libc: remove getsEd Maste2019-09-011-1/+1
| | | | | | | | | | | | | | | | | | | | gets is unsafe and shouldn't be used (for many years now). Leave it in the existing symbol version so anything that previously linked aginst it still runs, but do not allow new software to link against it. (The compatability/legacy implementation must not be static so that the symbol and in particular the compat sym gets@FBSD_1.0 make it into libc.)

| | | | | | | | | | | | | | | | Summary: Toolchain follow-up to r349350. LLVM patches will be submitted upstream for 9.0 as well. The bsd.cpu.mk change is required because GNU ld assumes BSS-PLT if it cannot determine for certain that it needs Secure-PLT, and some binaries do not compile in such a way to make it know to use Secure-PLT.

* i386 4/4G split.Konstantin Belousov2018-04-131-1/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The change makes the user and kernel address spaces on i386 independent, giving each almost the full 4G of usable virtual addresses except for one PDE at top used for trampoline and per-CPU trampoline stacks, and system structures that must be always mapped, namely IDT, GDT, common TSS and LDT, and process-private TSS and LDT if allocated. By using 1:1 mapping for the kernel text and data, it appeared possible to eliminate assembler part of the locore.S which bootstraps initial page table and KPTmap. The code is rewritten in C and moved into the pmap_cold(). The comment in vmparam.h explains the KVA layout. There is no PCID mechanism available in protected mode, so each kernel/user switch forth and back completely flushes the TLB, except for the trampoline PTD region. The TLB invalidations for userspace becomes trivial, because IPI handlers switch page tables. On the other hand, context switches no longer need to reload %cr3. copyout(9) was rewritten to use vm_fault_quick_hold(). An issue for new copyout(9) is compatibility with wiring user buffers around sysctl handlers. This explains two kind of locks for copyout ptes and accounting of the vslock() calls. The vm_fault_quick_hold() AKA slow path, is only tried after the 'fast path' failed, which temporary changes mapping to the userspace and copies the data to/from small per-cpu buffer in the trampoline. If a page fault occurs during the copy, it is short-circuit by exception.s to not even reach C code. The change was motivated by the need to implement the Meltdown mitigation, but instead of KPTI the full split is done. The i386 architecture already shows the sizing problems, in particular, it is impossible to link clang and lld with debugging. I expect that the issues due to the virtual address space limits would only exaggerate and the split gives more liveness to the platform.
