2004-02-27cope with MACHINE_ARCH changing from x86_64 to amd64. For now, we wantTheo de Raadt
the toolchain to remain at the name x86_64. Tested on all other architectures that care. Done as very small snippets, so that espie does not blow a fuse.

2003-08-01A working gcc 2.95/m88k compiler, for some low standard value of working.Miod Vallat
Configuration settings mostly borrowed from the former gcc 2.8 configuration. A few typos and fixes backported from gcc 3.3, and a hell lot of fixes from my fingertips. This is enough to yield a compiler which will produce correct code at -O0. Optimization is slightly broken for some constructs, and more fixes are in the pipeline. ok deraadt@

2003-01-30Again this comment was not updated. now we have 7 load sections.Dale Rahn
2003-01-30ELF security enhancement: put .rodata into it's own load section insteadDale Rahn
of putting it with the text. This removes the execute permission from readonly data. This constrains the executable region to portions of the executable which need to be executable. Note: not all processors or mmus are capable of -X protection at the page level, but should handle ELF images which specify specific RWX protections on each section.
2003-01-24This is a project to modify executables so that they do not have anyDale Rahn
executable regions which are writable. If a section of an executable is writable and executable, it is much easier for errant code to modify the executable's behavior. Two current areas in shared library environments which have this critical problem are the GOT (Global Offset Table) and PLT (Procedure Linkage Table). The PLT is required to be executable and both GOT and PLT are writable on most architectures. On most ELF architecture machines this would cause shared libraries to have data and BSS marked as executable. Padding to the linker script for programs and shared libraries/objects to isolate the GOT and PLT into their own load sections in the executables. This allows only the text(readonly) region and the PLT region to be marked executable with the normal data and BSS not marked as executable. The PLT region is still marked executable on most architectures because the PLT lives in the "data" or "BSS" regions and the dynamic loader will need to modify it. Since the GOT and PLT should only ever be written by the dynamic linker, it will be modified to mprotect those regions so that they are not writable during normal execution. If the dynamic linker needs to modify the regions later, (eg for lazy binding), it will mprotect the region, make the necessary changes, and mprotect it back. Since it is possible to receive a signal which would interrupt the program flow and perhaps cause the dynamic linker to modify the same (or nearby) PLT references, it is now necessary for signals to be blocked for the duration of the mprotect. This diff was omitted from the original commit, this implements the -Z option to produce traditional (non protected) executables.
