[Bug ld/20283] New: Make -z relro the default if possible
https://sourceware.org/bugzilla/show_bug.cgi?id=20283 Bug ID: 20283 Summary: Make -z relro the default if possible Product: binutils Version: 2.27 (HEAD) Status: NEW Severity: normal Priority: P2 Component: ld Assignee: unassigned at sourceware dot org Reporter: hjl.tools at gmail dot com Target Milestone: --- Since "-z relro" makes more pages read-only after relocation, I'd like to make it the default if possible. The following ELF targets don't support "-z relro": check.arc-linux-uclibc:FAIL: strip -z relro -shared (relro1) check.arc-linux-uclibc:FAIL: objcopy -z relro -shared (relro1) check.arc-linux-uclibc:FAIL: objcopy -z relro (tdata1) check.arc-linux-uclibc:FAIL: objcopy -shared -z relro (tdata1) check.arc-linux-uclibc:FAIL: objcopy -z relro (tdata2) check.arc-linux-uclibc:FAIL: objcopy -shared -z relro (tdata2) check.arc-linux-uclibc:FAIL: objcopy -z relro (tdata3) check.arc-linux-uclibc:FAIL: objcopy -shared -z relro (tdata3) check.arc-linux-uclibc:FAIL: objcopy -shared -z relro (tbss1) check.arc-linux-uclibc:FAIL: objcopy -shared -z relro (tbss2) check.arc-linux-uclibc:FAIL: objcopy -shared -z relro (tbss3) check.frv-linux:FAIL: strip -z relro (relro1) check.frv-linux:FAIL: strip -z relro -shared (relro1) check.frv-linux:FAIL: objcopy -z relro (relro1) check.frv-linux:FAIL: objcopy -z relro -shared (relro1) check.frv-linux:FAIL: objcopy -z relro (tdata1) check.frv-linux:FAIL: objcopy -shared -z relro (tdata1) check.frv-linux:FAIL: objcopy -z relro (tdata2) check.frv-linux:FAIL: objcopy -shared -z relro (tdata2) check.frv-linux:FAIL: objcopy -z relro (tdata3) check.frv-linux:FAIL: objcopy -shared -z relro (tdata3) check.frv-linux:FAIL: objcopy -shared -z relro (tbss1) check.frv-linux:FAIL: objcopy -shared -z relro (tbss2) check.frv-linux:FAIL: objcopy -shared -z relro (tbss3) check.hppa64-linux:FAIL: strip -z relro (relro1) check.hppa64-linux:FAIL: strip -z relro -shared (relro1) check.hppa64-linux:FAIL: objcopy -z relro (relro1) check.hppa64-linux:FAIL: objcopy -z relro -shared (relro1) check.hppa64-linux:FAIL: objcopy -z relro (tdata1) check.hppa64-linux:FAIL: objcopy -shared -z relro (tdata1) check.hppa64-linux:FAIL: objcopy -z relro (tdata2) check.hppa64-linux:FAIL: objcopy -shared -z relro (tdata2) check.hppa-linux:FAIL: strip -z relro (relro1) check.hppa-linux:FAIL: strip -z relro -shared (relro1) check.hppa-linux:FAIL: objcopy -z relro (relro1) check.hppa-linux:FAIL: objcopy -z relro -shared (relro1) check.hppa-linux:FAIL: objcopy -z relro (tdata1) check.hppa-linux:FAIL: objcopy -shared -z relro (tdata1) check.hppa-linux:FAIL: objcopy -z relro (tdata2) check.hppa-linux:FAIL: objcopy -shared -z relro (tdata2) check.hppa-linux:FAIL: objcopy -z relro (tdata3) check.hppa-linux:FAIL: objcopy -shared -z relro (tdata3) check.hppa-linux:FAIL: objcopy -shared -z relro (tbss1) check.hppa-linux:FAIL: objcopy -shared -z relro (tbss2) check.hppa-linux:FAIL: objcopy -shared -z relro (tbss3) check.ia64-linux:FAIL: strip -z relro (relro1) check.ia64-linux:FAIL: strip -z relro -shared (relro1) check.ia64-linux:FAIL: objcopy -z relro (relro1) check.ia64-linux:FAIL: objcopy -z relro -shared (relro1) check.ia64-linux:FAIL: objcopy -z relro (tdata1) check.ia64-linux:FAIL: objcopy -shared -z relro (tdata1) check.ia64-linux:FAIL: objcopy -z relro (tdata2) check.ia64-linux:FAIL: objcopy -shared -z relro (tdata2) check.ia64-linux:FAIL: objcopy -z relro (tdata3) check.ia64-linux:FAIL: objcopy -shared -z relro (tdata3) check.ia64-linux:FAIL: objcopy -shared -z relro (tbss1) check.ia64-linux:FAIL: objcopy -shared -z relro (tbss2) check.ia64-linux:FAIL: objcopy -shared -z relro (tbss3) check.mips64-linux:FAIL: objcopy -shared -z relro (tbss1) check.mips64-linux:FAIL: objcopy -shared -z relro (tbss2) check.mips64-linux:FAIL: objcopy -shared -z relro (tbss3) check.mipsel-linux-gnu:FAIL: objcopy -shared -z relro (tbss1) check.mipsel-linux-gnu:FAIL: objcopy -shared -z relro (tbss2) check.mipsel-linux-gnu:FAIL: objcopy -shared -z relro (tbss3) check.mipsisa32el-linux:FAIL: objcopy -shared -z relro (tbss1) check.mipsisa32el-linux:FAIL: objcopy -shared -z relro (tbss2) check.mipsisa32el-linux:FAIL: objcopy -shared -z relro (tbss3) check.mips-linux:FAIL: objcopy -shared -z relro (tbss1) check.mips-linux:FAIL: objcopy -shared -z relro (tbss2) check.mips-linux:FAIL: objcopy -shared -z relro (tbss3) We can make "-z relro" opt-in or opt-out.

[Bug gas/20247] AVR/ARM align causes unnecessary padding of segment
https://sourceware.org/bugzilla/show_bug.cgi?id=20247 --- Comment #6 from Nick Clifton --- Hi BG, > Also I just posted a patch I wrote. Currently I'm running my own branch () > at https://c0de.pw/bg/binutils-gdb . The problem with that patch is that it might break programs which depend upon the current behaviour. A better approach, I think, would be a patch which adds a new command line option to disable section padding. (Presumably on the assumption that the linker will take care of aligning sections so that they start on a suitable alignment boundary, padding the previous section if necessary). Something like the uploaded patch ? Would you care to try it out ?
