*	textrel support, cheap and ugly	Rich Felker	2011-06-29	1	-0/+5
\|
*	reclaim the memory wasted by dynamic linking for use by malloc	Rich Felker	2011-06-28	1	-0/+39
\|
*	use load address from elf header if possible	Rich Felker	2011-06-28	1	-1/+1
\| \| \| \| \| \| \| \| \|	this is mostly useless for shared libs (though it could help for prelink-like purposes); the intended use case is for adding support for calling the dynamic linker directly to run a program, as in: ./libc.so ./a.out foo this usage is not yet supported.
*	make dynamic linker relocate the main program image last, after all libs	Rich Felker	2011-06-28	1	-0/+1
\| \| \| \| \|	prior to this change, copy relocations for initialized pointer variables would not reflect the relocated contents of the pointer.
*	fix stale pointer issue in dynamic linker with dlopen	Rich Felker	2011-06-26	1	-0/+1
\|
*	don't leave the lock held on dlopen failure..	Rich Felker	2011-06-26	1	-2/+2
\|
*	add RTLD_DEFAULT support	Rich Felker	2011-06-26	1	-1/+2
\|
*	in dlopen: don't use null pointer	Rich Felker	2011-06-26	1	-3/+3
\| \| \| \|	deps can be null if a library has no dependencies (such as libc itself)
*	fix resolving symbols in objects loaded in RTLD_LOCAL mode	Rich Felker	2011-06-26	1	-0/+11
\| \| \| \| \| \|	basically we temporarily make the library and all its dependencies part of the global namespace but only for the duration of performing relocations, then return them to their former state.
*	experimental dlopen/dlsym and dynlink changes needed to support them	Rich Felker	2011-06-26	1	-8/+125
\|
*	error handling in dynamic linking	Rich Felker	2011-06-26	1	-2/+19
\| \| \| \| \| \|	some of the code is not yet used, and is in preparation for dlopen which needs to be able to handle failure loading libraries without terminating the program.
*	fix some symbol resolution issues in dynamic linker	Rich Felker	2011-06-25	1	-4/+4
\| \| \| \| \|	1. search was wrongly beginning with lib itself rather than dso head 2. inconsistent resolution of function pointers for functions in plt
*	handle library paths better (ignore empty path components, etc.)	Rich Felker	2011-06-25	1	-3/+5
\|
*	fix possible (questionable) strict aliasing violations and ptr arith	Rich Felker	2011-06-25	1	-3/+3
\|
*	proper path searching for dynamic linker	Rich Felker	2011-06-25	1	-14/+38
\| \| \| \| \|	first, use $LD_LIBRARY_PATH unless suid. if that fails, read path from /etc/ld-musl-$ARCH.path and fallback to a builtin default.
*	discard dso descriptors after performing relocations	Rich Felker	2011-06-25	1	-0/+12
\| \| \| \| \|	eventually (once dlopen exists) this behavior will be conditional on dlopen/dlsym not being reachable.
*	keep track of which dsos have been relocated	Rich Felker	2011-06-25	1	-0/+1
\|
*	prepare support for LD_LIBRARY_PATH (checking suid/sgid safety)	Rich Felker	2011-06-23	1	-0/+6
\| \| \| \| \| \| \| \| \| \|	the use of this test will be much stricter than glibc and other typical implementations; the environment will not be honored whatsoever unless the program is confirmed non-suid/sgid by the aux vector the kernel passed in. no fallback to slow syscall-based checking is used if the kernel fails to provide the information; we simply assume the worst (suid) in this case and refuse to honor environment.
*	dynamic linker 64bit fix: hash table entries are always 32bit	Rich Felker	2011-06-18	1	-2/+2
\|
*	experimental dynamic linker!	Rich Felker	2011-06-18	1	-0/+385
	some notes: - library search path is hard coded - x86_64 code is untested and may not work - dlopen/dlsym is not yet implemented - relocations in read-only memory won't work
