wireguard-openbsd/lib/libc/arch/powerpc/string, branch master WireGuard implementation for the OpenBSD kernel https://git.zx2c4.com/wireguard-openbsd/atom/lib/libc/arch/powerpc/string?h=master 2020-11-28T19:49:30Z Add retguard to macppc kernel locore.S, ofwreal.S, setjmp.S 2020-11-28T19:49:30Z gkoehler gkoehler@openbsd.org 2020-11-28T19:49:30Z urn:sha1:15572fcf8c6bfa0588565cd23f393a5a1499ea57 This changes RETGUARD_SETUP(ffs) to RETGUARD_SETUP(ffs, %r11, %r12) and RETGUARD_CHECK(ffs) to RETGUARD_CHECK(ffs, %r11, %r12) to show that r11 and r12 are in use between setup and check, and to pick registers other than r11 and r12 in some kernel functions. ok mortimer@ deraadt@ Retguard asm macros for powerpc libc, ld.so 2020-10-26T22:07:05Z gkoehler gkoehler@openbsd.org 2020-10-26T22:07:05Z urn:sha1:d2c5a4743fb945f45b034a3a830a96f7e1bc695d Add retguard to some, but not all, asm functions in libc. Edit SYS.h in libc to remove the PREFIX macros and add SYSENTRY (more like aarch64 and powerpc64), so we can insert RETGUARD_SETUP after SYSENTRY. Some .S files in this commit don't get retguard, but do stop using the old prefix macros. Tested by deraadt@, who put this diff in a macppc snap.

Then, apply that framework to most of the functions in stdio.h, string.h, err.h, and wchar.h.

A nice harsh undefined behaviour. We will clean the entire userland of the remaining issues in this catagory, then switch to the optimised memcpy which skips the memmove check. I tried to cut this change into pieces, but testing each sub-step on every architecture is too time consuming and mindnumbing. ok miod junk space 2009-04-29T18:21:46Z deraadt deraadt@openbsd.org 2009-04-29T18:21:46Z urn:sha1:a28daedfc357b214be5c701aa8ba8adb29a7f1c2 missing parts from last commit 1999-04-25T00:23:57Z millert millert@openbsd.org 1999-04-25T00:23:57Z urn:sha1:62a742911104f98b9185b2c6b6007d9b1c36396c Check-in of powerpc library support. 1996-12-21T20:42:21Z rahnds rahnds@openbsd.org 1996-12-21T20:42:21Z urn:sha1:a4afd6dad3fba28f80e70208181c06c482259988 NOTE: This will not work until the other pieces are checked in.
