Ok, people, heads up -- I'm about to commit a patch to /sys/i386 which changes the way FreeBSD uses the x86 LDT. Specifically, I'm moving LUDATA_SEL from LDT entry 4 to 5 (Why 5? Why not?) and re-using entry 4 as a call gate for SysV system calls made by library stubs from Solaris 2.6 and higher. I've been running with these mods for about a month now with no problems at all (there are no userland implications AFAICT). Nevertheless, I'm going to leave this in for a couple of days before committing the rest of the emulator to give interested parties a chance to bitch at me :-) Cheers, - mark -------------------------------------------------------------------- I tried an internal modem, newton@atdot.dotat.org but it hurt when I walked.
