Lu <hjl.tools at gmail dot com> --- > Linker should refuse to generate binary with STT_GNU_IFUNC symbol and TEXTREL. Isnt this similar to execstack in some sense? I presume SELinux disallows that too but that we do not completely ban that on non-secure OS. I dont understand this as much as you do but I like Paul's idea here: "I think it would be nice to have behavior other than what's currently happening. Either ld.so should support TEXTREL binaries with IFUNCs, or it should refuse to run them. I guess it could also try to make W+E page, and IF that fails, issue a warning and change to current behavior. That way, a TEXTREL+IFUNC binary will run correctly outside SELinux, will warn, then crash under SELinux. A TEXTREL without IFUNC will also run correctly outside SELinux, and will warn but still work under SELinux (i.e. almost same as current behavior)." > > -- > You are receiving this mail because: > You are on the CC list for the bug. > You reported the bug. -- You are receiving this mail because: You are on the CC list for the bug. _______________________________________________ bug-binutils mailing list bug-binutils@gnu.org https://lists.gnu.org/mailman/listinfo/bug-binutils
