wireguard-openbsd/sys/lib/libkern/arch, branch master WireGuard implementation for the OpenBSD kernel https://git.zx2c4.com/wireguard-openbsd/atom/sys/lib/libkern/arch?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@ Retguared asm macros for powerpc libkern 2020-10-27T01:26:53Z gkoehler gkoehler@openbsd.org 2020-10-27T01:26:53Z urn:sha1:9df9de38a103c48c52fb9b44dcfb01d26c3d4100 This was in the macppc snap, but I forgot to include it in my last commit "Retguard asm macros for powerpc libc, ld.so" Use the retguard macros from asm.h to protect the function. 2020-10-16T23:43:26Z deraadt deraadt@openbsd.org 2020-10-16T23:43:26Z urn:sha1:4efbe95c75086b3a7b0074651bfa04fd58990a98 ok mortimer kettenis The kernel and bootblocks never reference this file... 2020-07-18T17:13:44Z deraadt deraadt@openbsd.org 2020-07-18T17:13:44Z urn:sha1:cfcb7802d05fddbf08e08b5b229bfd9fd3505a03 Provide an optimized implementation of ffs(3) in the kernel on 2020-06-10T20:19:29Z naddy naddy@openbsd.org 2020-06-10T20:19:29Z urn:sha1:d41240fab998b3c42f736af0544339ebedba7e73 arm64/powerpc/powerpc64, making use of the count leading zeros instruction. powerpc testing by cwen@; ok kettenis@ deraadt@ Give some END()s to assembly symbols. 2019-11-05T08:16:43Z mpi mpi@openbsd.org 2019-11-05T08:16:43Z urn:sha1:6abd9ea796a8bef365c616b03174fbc2051daf73 ok kettenis@, jca@ Add movstrSI12_i4 for linking -Os/-Oz kernels.
