Implement fate#326356 This combines commits afca762f and a381372 to implement RELRO properly on s390. Before that the order of .got.plt vs. .got was such that the latter couldn't be made read-only when lazy linking was enabled. commit afca762f598d453c563f244cd3777715b1a0cb72 Author: Andreas Krebbel <krebbel@linux.vnet.ibm.com> Date: Thu Dec 21 13:12:03 2017 +0100 S/390: Improve partial relro support for 64 bit Currently on S/390 the .got.plt always comes first which prevents the GNU_RELRO segment from being extended across the non-plt GOT entries. Just swapping both unfortunately is not that simple since our ABI requires the _GLOBAL_OFFSET_TABLE_ symbol to point to the very beginning of the entire GOT. Of the 3 magic GOT entries the first is accessed via got pointer while second and third are being accessed via DT_PLTGOT. In order to keep them together we make DT_PLTGOT to point to the .got instead of .got.plt. However, this violates an assumption in the dynamic linker prelink undo code about the GOTPLT entries starting at DT_PLTGOT + 3. We got rid of this requirement with a Glibc patch already in version 2.24: https://sourceware.org/ml/libc-alpha/2016-06/msg01302.html So the S/390 relro GOT layout will look like this with this patch: +----------------------------------+ |got[0]: DYNAMIC | <--- _GLOBAL_OFFSET_TABLE_ == DT_PLTGOT .got |got[1]: link_map parm | |got[2]: &_dl_runtime_resolve | +----------------------------------+ | | non-plt GOT entries | | | | +----------------------------------+ | | <--- .gotplt, PLT GOT entries | | | | | | +----------------------------------+ The patch detects the current layout in size_dynamic_section in order to deal also with linker scripts not generated by this ld version. With partial relro enabled we pick a linker script where .got and .got.plt are swapped which then triggers the rest of the logic. ld/ChangeLog: 2018-07-18 Andreas Krebbel <krebbel@linux.ibm.com> * emulparams/elf64_s390.sh: Define GENERATE_RELRO_SCRIPT and SEPARATE_GOTPLT. * testsuite/ld-s390/gotreloc_64-relro-1.dd: New test. * testsuite/ld-s390/gotreloc_64-norelro-1.dd: Renamed from ... * testsuite/ld-s390/gotreloc_64-1.dd: ... this. * testsuite/ld-s390/s390.exp: Split the GOT testcase into two. bfd/ChangeLog: 2018-07-18 Andreas Krebbel <krebbel@linux.ibm.com> * elf-s390-common.c (s390_gotplt_after_got_p): New function.

This is necessary for e.g. S/390 where usually the .got.plt comes first and prevents the relro segment from being extended across the non-plt GOT entries. The patch started with the work from Marcin taken from the mwk user branches. However, the patch needed substantial changes due to the 'separate code' feature which got committed in the meantime. ld/ChangeLog: 2018-07-18 Andreas Krebbel <krebbel@linux.ibm.com> Marcin Kościelnicki <koriakin@0x04.net> * emultempl/elf32.em: Add code to pick dedicated linker scripts for partial relro. * genscripts.sh: Generate dedicated linker scripts for partial relro.
