stage 3 then uses the + saved addends in place of the inline ones which were clobbered. for + stack safety, a hard limit (currently 4k) is imposed on the number of + such addends; this should be a couple orders of magnitude larger than + the actual need. this number is not a runtime variable that could + break fail-safety; it is constant for a given libc.so build. + +commit 768b82c6de24e480267c4c251c440edfc71800e3 +Author: Rich Felker +Date: Mon May 25 19:15:17 2015 -0400 + + move call to dynamic linker stage-3 into stage-2 function + + this move eliminates a duplicate "by-hand" symbol lookup loop from the + stage-1 code and replaces it with a call to find_sym, which can be + used once we're in stage 2. it reduces the size of the stage 1 code, + which is helpful because stage 1 will become the crt start file for + static-PIE executables, and it will allow stage 3 to access stage 2's + automatic storage, which will be important in an upcoming commit. + +commit 967bcbf67c3ffac587de4d79abc1e5e072d83e3e +Author: Rich Felker +Date: Mon May 25 16:02:49 2015 -0400 + + mark mips crt code as code + + otherwise disassemblers treat it as data. + +commit 7b75c4877ddf22f219f944c61d939df1dee4f6d3 +Author: Rich Felker +Date: Mon May 25 15:56:36 2015 -0400 + + mark mips cancellable syscall code as code + + otherwise disassemblers treat it as data. + +commit 0e0e49421f08cfd670975ecd3604f7f9015e1833 +Author: Rich Felker +Date: Mon May 25 00:32:37 2015 -0400 + + simplify/shrink relocation processing in dynamic linker stage 1 + + the outer-loop approach made sense when we were also processing + DT_JMPREL, which might be in REL or RELA form, to avoid major code + duplication. commit 09db855b35709aa627d7055c57a98e1e471920ab removed + processing of DT_JMPREL, and in the remaining two tables, the format + (REL or RELA) is known by the name of the table. simply writing two + versions of the loop results in smaller and simpler code. + +commit 09db855b35709aa627d7055c57a98e1e471920ab +Author: Rich Felker +Date: Mon May 25 00:25:56 2015 -0400 + + remove processing of DT_JMPREL from dynamic linker stage 1 bootstrap + + the DT_JMPREL relocation table necessarily consists entirely of + JMP_SLOT (REL_PLT in internal nomenclature) relocations, which are + symbolic;

global data accesses on + powerpc seem to be using a translation-unit-local GOT filled via + R_PPC_ADDR32 relocations rather than R_PPC_GLOB_DAT. being a non-GOT + relocation type, these were not reprocessed after adding the main + application and its libraries to the chain, causing libc code not to + see copy relocations in the main program, and therefore to use the + pre-copy-relocation addresses for global data objects (like environ). + + the motivation for the dynamic linker only reprocessing GOT/PLT + relocation types in stage 3 is that these types always have a zero + addend, making them safe to process again even if the storage for the + addend has been clobbered. other relocation types which can be used + for address constants in initialized data objects may have non-zero + addends which will be clobbered during the first pass of relocation + processing if they're stored inline (REL form) rather than out-of-line + (RELA form). + + powerpc generally uses only

__set_thread_area is called more than once by reusing + the GDT slot already in the %gs register, and only setting up a new + GDT slot when %gs is zero. this created a hidden assumption that %gs + is zero when a new process image starts, which is true in practice on + Linux, but does not seem to be documented ABI, and fails to hold under + qemu app-level emulation. + + while it would in theory be possible to zero %gs in the entry point + code, this code is shared between static and dynamic binaries, and + dynamic binaries must not clobber the value of %gs already setup by + the dynamic linker. + + the alternative solution implemented in this commit simply uses global + data to store the GDT index that's selected. __set_thread_area should + only be called in the initial thread anyway (subsequent threads get + their thread pointer setup by __clone), but even if it were called by + another thread, it would simply read and write back the same GDT index + that was already assigned to the initial thread, and thus (in the x86 + memory model) there is no data race. + +commit c0f10cf06725bd0de37f3ced7954a653bf9f1049 +Author: Rich Felker +Date: Thu May 14 18:51:27 2015 -0400 + + make
