In libc, get pagesize from auxv; cache that between getpagesize() and sysconf(_SC_PAGESIZE) ok mpi@ "good time" deraadt@ In static binaries, invoke kbind() once to disable it. 2015-09-01T05:40:06Z guenther guenther@openbsd.org 2015-09-01T05:40:06Z urn:sha1:0a8a9c346022d9ea9d2d120f75edf8549c4915cf With much assistance from miod@ ok deraadt@@ Introduce new csu0 variant for -static -pie binaries to use called 2014-12-22T03:51:08Z kurt kurt@openbsd.org 2014-12-22T03:51:08Z urn:sha1:b7d44ead2528d548ebe369571fb766478149400a rcsu0.o where the initial 'r' is for relocatable. rcsu0.o performs self-relocation on static pie binaries by calling a slightly modified copy of ld.so's _dl_boot_bind() in boot.h. The first arch implementatation is also included for amd64 where __start calls _dl_boot_bind() and then calls ___start(). Includes parts from kettenis@ to help get R_X86_64_64 relocations working and proper handling for undefined weak symbols. This is the first part of several to get static pie self-relocating binaries working. binutils, gcc and kernel changes are forthcoming to complete the solution, then per-arch implementations are needed for MD_RCRT0_START in csu. okay kettenis@ pascal@ deraadt@ Merge the per-arch crt0.c files into common_elf/crt0.c, with MD macros in 2013-12-03T06:21:40Z guenther guenther@openbsd.org 2013-12-03T06:21:40Z urn:sha1:453b49cd27aaae4d675fbaa755fa5bd0af309909 the md_init.h files.
