Jesper Schmitz Mouridsen <jsm@FreeBSD.org> has asked freebsd-gecko (Nobody) <gecko@FreeBSD.org> for maintainer-approval: Bug 271081: www/firefox: crashes on arm64 with ASLR enabled https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=271081 Attachment 247141: allows running with aslr and fixes jit.. https://bugs.freebsd.org/bugzilla/attachment.cgi?id=247141&action=edit --- Comment #15 from Jesper Schmitz Mouridsen <jsm@FreeBSD.org> --- Created attachment 247141 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=247141&action=edit allows running with aslr and fixes jit.. The memory part MAP_FIXED is to avoid (desired != region) (do not know how that relates to aslr but with this it runs with aslr), the jit code has to do some cache sync in order to execute the wirte+exec pages, it was guarded out, and the problem was masked under w^x because mprotect also does some cache syncing.. ,thanks Kyle Evans. Hopefully someone will pick this up for a test. Do not forget bug #275247 Only tested on aarch64 rpi4 and rk3399.
