| | | | | | | | | | | The requirement is for a GCC-compatible compiler and not necessarily GCC itself. However, we currently expect any compiler used for building the whole of FreeBSD to be GCC-compatible and many things will break if not; there's no longer a need to have an explicit test for this in rtld.

* Change interpretation of the DF_ORIGIN and DF_1_ORIGIN flags.kib2015-04-271-36/+45
| | | | | | | | | | | | | | | | According to standard, the presence of the flags only means that the object path must be resolved at the time object loading, instead of my reading that the flag is required to enable token substitution at all. The consequence is that -z origin linker flag is no longer required for the token substitution in the run/rpath or the needed library soname. It is only recommended if token substition is needed at dlopen(3) time, since namecache might drop the required entries at the time of resolution.

* The runtime linker needs to include a path to itself in the link mapjhb2014-12-021-0/+2
| | | | | | | | | | | | | | | it exports to the debugger. It currently has two choices: it can use a compiled-in path (/libexec/ld-elf.so.1) or it can use the path stored in the interpreter path in the binary being executed. The runtime linker currently prefers the second. However, this is usually wrong for compat32 binaries since the binary specifies the path of rtld on a 32-bit system (/libexec/ld-elf.so.1) instead of the actual path (/libexec/ld-elf32.so.1). For now, always assume the compiled in path (/libexec/ld-elf32.so.1) as the rtld path and ignore the path in the binary for the 32-bit runtime linker.

| | | | | | | | | | | | | | | | | | | you all as /dev/random. This code has had an extensive rewrite and a good series of reviews, both by the author and other parties. This means a lot of code has been simplified. Pluggable structures for high-rate entropy generators are available, and it is most definitely not the case that /dev/random can be driven by only a hardware souce any more. This has been designed out of the device. Hardware sources are stirred into the CSPRNG (Yarrow, Fortuna) like any other entropy source. Pluggable modules may be written by third parties for additional sources. The harvesting structures and consequently the locking have been simplified. Entropy harvesting is done in a more general way (the documentation for this will follow). There is some GREAT entropy to be had in the UMA allocator, but it is disabled for now as messing with that is likely to annoy many people. The venerable (but effective) Yarrow algorithm, which is no longer supported by its authors now has an alternative, Fortuna. For now, Yarrow is retained as the default algorithm, but this may be changed using a kernel option. It is intended to make Fortuna the default algorithm for 11.0. Interested parties are encouraged to read ISBN 978-0-470-47424-2 "Cryptography Engineering" By Ferguson, Schneier and Kohno for Fortuna's gory details. Heck, read it anyway. Many thanks to Arthur Mesh who did early grunt work, and who got caught in the crossfire rather more than he deserved to. My thanks also to folks who helped me thresh this out on whiteboards and in the odd "Hallway track", or otherwise. My Nomex pants are on. Let the feedback commence!

* Revert r267233 for now. PIE support needs to be reworked.bdrewery2014-08-194-8/+0
| | | | | | | | | | | | | | | | | | | | | | | | 1. 50+% of NO_PIE use is fixed by adding -fPIC to INTERNALLIB and other build-only utility libraries. 2. Another 40% is fixed by generating _pic.a variants of various libraries. 3. Some of the NO_PIE use is a bit absurd as it is disabling PIE (and ASLR) where it never would work anyhow, such as csu or loader. This suggests there may be better ways of adding support to the tree. Many of these cases can be fixed such that -fPIE will work but there is really no reason to have it in those cases. 4. Some of the uses are working around hacks done to some Makefiles that are really building libraries but have been using bsd.prog.mk because the code is cleaner. Had they been using bsd.lib.mk then NO_PIE would not have been needed. We likely do want to enable PIE by default (opt-out) for non-tree consumers (such as ports). For in-tree though we probably want to only enable PIE (opt-in) for common attack targets such as remote service daemons and setuid utilities. This is also a great performance compromise since ASLR is expected to reduce performance. As such it does not make sense to enable it in all utilities such as ls(1) that have little benefit to having it enabled. Reported by: kib
