[Bug ld/29411] ld warning on SPARC: LOAD segment with RWX permissions
https://sourceware.org/bugzilla/show_bug.cgi?id=29411 Nick Clifton changed: What|Removed |Added Resolution|--- |FIXED CC||nickc at redhat dot com Status|NEW |RESOLVED --- Comment #2 from Nick Clifton --- Hi Rainer, The warning is intended to alter users to the fact that a segment has been created with all three permission flags set - something that is very tempting to attackers looking to inject code into a binary. Disabling the warning for specific target configurations is possible however. There is a section of code at the start of ld/configure.tgt to do this. I have gone ahead and added the sparc-solaris targets to the list of targets for which the warning should be supressed by default. (It can still be enabled via a command line option, if the user so desires). Cheers Nick -- You are receiving this mail because: You are on the CC list for the bug.

However, this is not a Solaris/SPARC-only issue: I first saw it on Linux/sparc64. Given the SPARC and SPARC V9 psABIs, I guess it affects at least all SPARC/ELF targets (if not SPARC in general).

Ah - I missed this. Would you mind applying a small patch on top of mine then, that tweaks the regexp for sparc targets ? (I am just a little bit swamped at the moment.

I'll check if we want this for all SPARC targets or restrict to some subset (ELF) somehow. -- You are receiving this mail because: You are on the CC list for the bug.
