A few weeks ago I recall someone else noticing that setgid programs can't work on Xenix. Is there a workaround? I'm running `386 2.3.1... I'd sure like to be able to use this someday! thanks -- Tan Bronson (home) tan@microvation.com (or tan@bronson.uucp) Microvation Consultants (work) bronson@multiflow.com Madison, CT 06443

Neither will SUID programs. It has to do with the way their emulator works. '386 Xenix binaries on Interactive do work however.

The bug is that if a program calls setgid(getgid()), and that program's effective uid isn't root, then the setgid() fails but returns -> zero <-. So it's saying "sure, no problem," but it's not doing anything. A workaround is: "setgid(getgid()); if (getegid() != getgid()) { PROBLEM }". -- You may redistribute this article only to those who may freely do likewise.
