that return ssize_t will not return a negative value upon error. Fixes dynamical loading of shared objects using dlopen(). ok guenther@

2018-04-27Make sure ld.so doesn't use floating point registers, as the lazy-bindingPhilip Guenther
stub doesn't preserve them and some may be used for passing arguments ok kettenis@ deraadt@ mlarkin@

2018-01-18Unlike other archs, mips64 needs ld.so to know about symbol visibility andPhilip Guenther
skip symbol lookup on protected symbols. Add visibility #defines to <sys/exec_elf.h> to support that. ok kettenis@ visa@
2017-12-24Fix one possible buffer overflow and one underflow. Also some minorTodd C. Miller
cleanups. From Jan Kokemueller. OK deraadt@
2017-12-21Implement missing bits to support lazy binding. Note that the codeMark Kettenis
deliberately does not save the floating-point argument registers before calling _dl_bind(). Doing so would force an FPU context switch upon every function call through the PLT. But since we compile ld.so with -march=armv8-a+nofp+nosimd this is safe since nothing in the _dl_bind() codepath uses he FPU registers. ok guenther@, drahn@

2017-12-01Redo the calculation of the alignment and placement of static TLS data toPhilip Guenther
correctly take into account the segment p_align. Previously, anything with a size belong the natural alignment or with alignment larger than the natural one would either not be intialized correctly, be misaligned, or result in the TIB being misaligned.

one location under /usr/share/relink. Be more specific in src/etc/rc reorder_libs() what filesystems need r/w remount and ensure that their mount state is restored. Idea and positive feedback from deraadt@ OK aja@ tb@

2017-10-26If LD_BIND_NOW is in force then all relocations are performed eagerly,Philip Guenther
when the object is loaded. Since kbind(2) will never be used in that case, disable it early, before invoking any library or application code. ok deraadt@ kettenis@
2017-10-24R_AARCH64_NONE should be zero, not 256. The latter was a deprecatedPhilip Guenther
assignment and isn't used by clang/lld. ok jsg@
2017-10-18Make blacklist entries override the whitelist. When running spamdTodd C. Miller
in greylisting mode, it is not uncommon for an IP to get whitelisted before it shows up on a spam blacklist. With this change, spamd will check its blacklists before adding a WHITE entry to the <spamd-white> pf table. If the IP matches a blacklist, the WHITE entry will be removed. OK phessler@

2017-09-03Fix m88k problem in recent ld.so changes.Kenji Aoyama
- move _dl_cerror function from SYS.h to ldasm.S to avoid duplicate definition when linking - [SYS.h] pull some macros from lib/libc/arch/m88k/DEFS.h - [ldasm.S] add "'never hit' but needed" br again in _dl_cacheflush (thanks to Miod Vallat) - [ldasm.S] change ld.hu into ld.h in order to get a correctly signed and sign-extended value (also thanks to Miod Vallat) ok deraadt@
