| * | Retguard sigsetjmp on powerpc64. |   mortimer | 2020-10-19 | 1 | -5/+10 |
| | | | | | ok deraadt@ | ||||
| * | add retguard prologue/epilogue |   deraadt | 2020-10-19 | 1 | -2/+4 |
| | | | | | ok mortimer | ||||
| * | Add powerpc64 retguard macros for setjmp / longjmp. | mortimer | 2020-10-18 | 1 | -5/+10 |
| | | | | | ok deraadt@ | ||||
| * | SYS___threxit cannot fail, but this integration looks like a gadget. | deraadt | 2020-10-18 | 1 | -1/+2 |
| | | | | | | Put a hard-trap instruction after the syscall instruction. ok kettenis mortimer | ||||
| * | Adapt SYS.h to use retguard macros from asm.h, so that generated system | deraadt | 2020-10-16 | 8 | -46/+77 |
| | | | | | | | calls are guarded. Adapt the first few hand-written functions to this model (a few remain) ok kettenis mortimer | ||||
| * | Fix two cases where we shpould compare/store 64-bit values instead of |   kettenis | 2020-07-27 | 1 | -3/+3 |
| | | | | | | | 32-bit values. ok gkoehler@, drahn@ | ||||
| * | Fix powerpc64's sbrk() |   gkoehler | 2020-07-27 | 1 | -3/+5 |
| | | | | | | | | Initialize __curbrk = &_end. It's a 64-bit pointer, so use ld/std instead of lwz/stw. ok drahn@ | ||||
| * | Fix TIB/TCB on powerpc64. Some bright sould decided that the TCB should | kettenis | 2020-07-14 | 1 | -3/+3 |
| | | | | | | | | | | | | be 8 bytes in the 64-bit ABI just like in the 32-bit ABI. But that means there is no "spare" word in the TCB that we can use to store a pointer to our struct pthread. So we have to treat powerpc64 special. Also recognize that the thread pointer points 0x7000 bytes after the TCB. Since the TCB is 8 bytes this means that TCB_OFFSET should be 0x7008. Pointed out by guenther@; ok deraadt@ | ||||

| * | Use a relative branch to jump from setjmp(3) into _setjmp(4). | kettenis | 2020-07-02 | 1 | -5/+4 |
| | | | | | Use correct register to reference the location where we store CR. | ||||
| * | Add missing comparison instruction. Load %r12 with the indirect branch | kettenis | 2020-06-30 | 1 | -1/+3 |
| | | | | | address to load the correct TOC address. | ||||
| * | Use C versions of bcopy(3) and memmove(3) for now as the assembly version | kettenis | 2020-06-29 | 1 | -2/+2 |
| | | | | | | | of bcopy(9) doesn't work in its current state. ok deraadt@ | ||||
| * | Use std instead of stw to store CR since we use std in sigsetjmp(3) and | kettenis | 2020-06-28 | 1 | -2/+2 |
| | | | | | we use ld to load it again in longjmp(3). | ||||
| * | The 2nd and 3rd argument are pointers, so use the appropriate doubleword | kettenis | 2020-06-28 | 1 | -5/+5 |

| | | | | | | | aarch64/powerpc/powerpc64, making use of the count leading zeros instruction. Also add a brief regression test. ok deraadt@ kettenis@ | ||||
| * | Fix TCB_OFFSET_ERRNO. Adjust comments to reflect that powerpc64 uses %r13 | kettenis | 2020-06-26 | 1 | -4/+4 |
| | | | | | | | as the per-thread register. ok patrick@, drahn@ | ||||
