[Sudoscript-devel] OpenBSD Problem Solved

[Howard O. <hb...@eg...>]

It was a hangover from the 1.x code in which I opened the singular FIFO
for read/write. This is an error in Solaris and OpenBSD. If it's also
an error in POSIX 1, then it's probably also an error in Linux. The
Linux and FreeBSD man pages for mkfifo(2) and open(2) don't mention a
O_RDWR restriction on FIFOs. OpenBSD does have such a restriction,
and returned an error when an attempt was made to open a fifo for
read/write. Solaris open(2) mentions the restriction, but the OS doesn't
complain when you actually open a FIFO this way.

In any case, the 2.0 architecture doesn't require two-way I/O on any
of the FIFOs, so getting rid of the O_RDWR mode on the front-end FIFO
in sudoshell and sudoscriptd fixes the problem for all platforms. The
code change is in CVS. I'm not going to cut another alpha release for
this. I'll roll it in to the first beta on Wednesday instead.
