https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D271081 Jesper Schmitz Mouridsen <jsm@FreeBSD.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Attachment #247141|maintainer-approval?(gecko@ | Flags|FreeBSD.org) | Attachment #247141|0 |1 is obsolete| | --- Comment #22 from Jesper Schmitz Mouridsen <jsm@FreeBSD.org> --- Created attachment 247827 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=3D247827&action= =3Dedit align mmap >From https://reviews.freebsd.org/rS343964 I concluded that MAP_FIXED simply turns of randomization(?) with aslr enabled.=20 With aslr enabled without the MAP_FIXED hack not all pages were aligned cau= sing calls to TryToAlignChunk which somehow causes failures. I cannot yet explain why TryToAlignChunk fails. It did not seem to ever get called with aslr disabled. Thus a second hackish attempt to fix running with aslr enabled on aarch64, is attached, which tries to ensure alignment to the desired alignm= ent, if I did not misread the mmap man page. I marked the other attachment obsol= ete because the jit part hopefully gets accepted by upstream. --=20 You are receiving this mail because: You are on the CC list for the bug.
