2016-11-07	fix ldso reserved library name handling	Szabolcs Nagy	-19/+19
	If a DT_NEEDED entry was the prefix of a reserved library name (up to the first dot) then it was incorrectly treated as a libc reserved name. e.g. libp.so dependency was not loaded as it matched libpthread reserved name.
2016-11-07	fix accidental global static pointer in ldso	Szabolcs Nagy	-1/+2
	this was harmless as load_library is not called concurrently, but it used one word of bss.
2016-03-06	generalize mips-specific reloc code not to hard-code sym/type encoding	Rich Felker	-1/+1
	this change is made in preparation for adding the mips64 port, which needs a 64-bit (and mips64-specific) form of the R_INFO macro, but it's a better abstraction anyway. based on part of the mips64 port patch by Mahesh Bodapati and Jaydeep Patil of Imagination Technologies.
2016-02-18	fix regression in SH/FDPIC dynamic linker	Rich Felker	-0/+2
	the dynamic linker was found to hang when used as the PT_INTERP, but not when invoked as a command. the mechanism of this failure was not determined, but the cause is clear: commit 5552ce52000855906a5cb4f08f2e456573cca51f removed the SHARED macro, but arch/sh/crt_arch.h is still using it to choose the right form of the crt/ldso entry point code. moving the forced definition from rcrt1.c to dlstart.c restores the old behavior. eventually the logic should be changed to fully remove the SHARED macro or at least rename it to something more reasonable.
2016-01-30	ldso: fix GDB dynamic linker info on MIPS	Felix Fietkau	-4/+7
	GDB is looking for a pointer to the ldso debug info in the data of the ..rld_map section. Signed-off-by: Felix Fietkau <nbd@openwrt.org>
2016-01-30	fix regression in dynamic-linked tls when both main app & libs have tls	Rich Felker	-1/+1
	commit d56460c939c94a6c547abe8238f442b8de10bfbd introduced this bug by setting up the tls module chain incorrectly when the main app has tls. the singly-linked list head pointer was setup correctly, but the tail pointer was not, so the first attempt to append to the list (for a shared library with tls) would treat the list as empty and effectively removed the main app from the list. this left all tls module id numbers off-by-one. this bug did not appear in any released versions.
2016-01-25	move dynamic linker to its own top-level directory, ldso	Rich Felker	-0/+2077
	this eliminates the last need for the SHARED macro to control how files in the src tree are compiled. the same code is used for both libc.a and libc.so, with additional code for the dynamic linker (from the new ldso tree) being added to libc.so but not libc.a. separate .o and .lo object files still exist for the src tree, but the only difference is that the .lo files are built as PIC. in the future, if/when we add dlopen support for static-linked programs, much of the code in dynlink.c may be moved back into the src tree, but properly factored into separate source files. in that case, the code in the ldso tree will be reduced to just the dynamic linker entry point, self-relocation, and loading of libraries needed by the main application.
