musl - The musl libc tree (WIP / dev branches)

Age	Commit message (Collapse)	Author	Files	Lines
2011-06-26	in dlopen: don't use null pointer	Rich Felker	1	-3/+3
	deps can be null if a library has no dependencies (such as libc itself)
2011-06-26	fix resolving symbols in objects loaded in RTLD_LOCAL mode	Rich Felker	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.
2011-06-26	experimental dlopen/dlsym and dynlink changes needed to support them	Rich Felker	1	-8/+125

2011-06-26	error handling in dynamic linking	Rich Felker	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.
2011-06-25	fix some symbol resolution issues in dynamic linker	Rich Felker	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
2011-06-25	handle library paths better (ignore empty path components, etc.)	Rich Felker	1	-3/+5

2011-06-25	fix possible (questionable) strict aliasing violations and ptr arith	Rich Felker	1	-3/+3

2011-06-25	proper path searching for dynamic linker	Rich Felker	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.
2011-06-25	discard dso descriptors after performing relocations	Rich Felker	1	-0/+12
	eventually (once dlopen exists) this behavior will be conditional on dlopen/dlsym not being reachable.
2011-06-25	keep track of which dsos have been relocated	Rich Felker	1	-0/+1

2011-06-23	prepare support for LD_LIBRARY_PATH (checking suid/sgid safety)	Rich Felker	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.
2011-06-18	dynamic linker 64bit fix: hash table entries are always 32bit	Rich Felker	1	-2/+2

2011-06-18	experimental dynamic linker!	Rich Felker	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
