I think we are one of the arch which does it. The same has been tested on x86 and arm, where ELF_ET_DYN_BASE doesn’t use randomize_et_dyn call, and it works properly as per the user-space definition of randomization; (i.e when at "echo 0 > /proc/sys/kernel/randomize_va_space", TEXT randomization should not happen.) > I'm not clear on what has changed to break this? > > cheers _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@lists.ozlabs.org https://lists.ozlabs.org/listinfo/linuxppc-dev
