Rich Felker	2fdea17c3d	fix dlopen UB due to longjmp/volatile rules violation	15 years ago
Rich Felker	191ebcac31	simple rpath support (no token expansion yet) for dynamic linker	15 years ago
Rich Felker	9f17413c75	textrel support, cheap and ugly	15 years ago
Rich Felker	6717e62ac0	reclaim the memory wasted by dynamic linking for use by malloc	15 years ago
Rich Felker	bf30100ad7	use load address from elf header if possible 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.	15 years ago
Rich Felker	c7debe13ee	make dynamic linker relocate the main program image last, after all libs prior to this change, copy relocations for initialized pointer variables would not reflect the relocated contents of the pointer.	15 years ago
Rich Felker	9e17b71fa6	fix stale pointer issue in dynamic linker with dlopen	15 years ago
Rich Felker	06933cc724	don't leave the lock held on dlopen failure..	15 years ago
Rich Felker	97507bde47	add RTLD_DEFAULT support	15 years ago
Rich Felker	0e4dae3d77	in dlopen: don't use null pointer deps can be null if a library has no dependencies (such as libc itself)	15 years ago
Rich Felker	92ab5d8d15	fix resolving symbols in objects loaded in RTLD_LOCAL mode 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.	15 years ago
Rich Felker	59ab43f5f8	experimental dlopen/dlsym and dynlink changes needed to support them	15 years ago
Rich Felker	6b3d5e508f	error handling in dynamic linking 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.	15 years ago
Rich Felker	32de61e81a	fix some symbol resolution issues in dynamic linker 1. search was wrongly beginning with lib itself rather than dso head 2. inconsistent resolution of function pointers for functions in plt	15 years ago
Rich Felker	49388f3b7b	handle library paths better (ignore empty path components, etc.)	15 years ago
Rich Felker	59633c736d	fix possible (questionable) strict aliasing violations and ptr arith	15 years ago
Rich Felker	568b8075a4	proper path searching for dynamic linker first, use $LD_LIBRARY_PATH unless suid. if that fails, read path from /etc/ld-musl-$ARCH.path and fallback to a builtin default.	15 years ago
Rich Felker	e8dbf00a78	discard dso descriptors after performing relocations eventually (once dlopen exists) this behavior will be conditional on dlopen/dlsym not being reachable.	15 years ago
Rich Felker	368ba4a0a9	keep track of which dsos have been relocated	15 years ago
Rich Felker	b7f6e0c6f8	prepare support for LD_LIBRARY_PATH (checking suid/sgid safety) 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.	15 years ago
Rich Felker	596d60c565	dynamic linker 64bit fix: hash table entries are always 32bit	15 years ago
Rich Felker	51e2d83102	experimental dynamic linker! 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	15 years ago
