@@ -97,6 +97,16 @@ Version 2.20 silently replaced with the "C" locale when running in AT_SECURE mode (e.g., in a SUID program). This is no longer necessary because of the additional checks. + +* On x86-64, the dynamic linker's lazy-binding support is now compatible + with application code using Intel MPX instructions. (With all previous + versions, the MPX register state could be clobbered when making calls + into or out of a shared library.) Note that while the new dynamic + linker is compatible with all known x86 hardware whether or not it + supports Intel MPX, some x86 instruction-set emulators might fail to + handle the new instruction encodings. This is known to affect Valgrind + versions up through 3.9 (but will be fixed in the forthcoming 3.10 + release), and might affect other tools that do instruction emulation. Version 2.19 |
