Utah Lites Release 1.1.u3

March 30, 1996

Overview

This release of Lites single server is to correspond with the Mach4 UK22 release. This release, called lites-1.1.u3, includes some enhancements made by the Flux project at the University of Utah, Ian Dall and Jukka Partanen. This release is mostly to include slice support for use with Mach4 UK22.

Please check the General Lites Information page for more information about other features of Lites.

New features include:

Signal handling fixes by Ian Dall.
Support for FreeBSD slice devices.
Minor fixes.

Please report problems to lites-bugs@cs.utah.edu.

Tested configurations

Intel x86:

All configurations were built using i386-mach cross-build tools, which can be found at: ftp://flux.cs.utah.edu/flux/binaries/i386.

Because of migrating threads complications with signals, this release dosen't work on the PA. The last released version that is known to work is The Utah PA-RISC Code Snapshot: version 2.

Details

Signal Changes

Major Changes:

Functions sendsig, send_signal, thread_psignal and thread_signal have been changed to return whether the process was notified of pending signals. The SAS_NOTIFY_DONE flag was added for this.
The functions tsleep_main, start_server_op, tsleep_main, bsd_take_signal, thread_signal now use the HAVE_SIGNALS and CURSIG macros instead of mucking around with p_siglist directly.
Make catch_exception_raise return unsuccessful status if the exception is handled by the task.

Slice Support

Lites now understands FreeBSD slice device numbers. This allows you to access DOS partitions from Lites without the need to resort to funky disklabels. Since Lites only passes device names to Mach, you also have to run Mach4 UK22 to use these, older kernels don't understand slice names. Using slice names can cause trouble because Lites has no way to know where the `compatibility' slice (ie. the standard device names without a slice designator get mapped to the first partition with a BSD disklabel) will be mapped, so you can mount the same partition twice: once with the compatability name, and once with it's slice name. For more information about slices, look at the Mach4 UK22 release page.

If you're running Lites on a version of FreeBSD greater than 2.0.5, then you should already have the slice devices, but if you're not then you'll have to make them. A version of the FreeBSD MAKEDEV which only includes the IDE and SCSI devices ( MAKEDEV.slice) can be found at the same location as Lites.1.1.u3.

To use slice names in your kernel, you can either specify --enable-slice on the configure command line, or add the +slice option to your configuration. Slice support is included in the LARGE configuration.

Minor Fixes

HP-UX compatability enhancements. This is basically what was in The Utah PA-RISC Snapshot 2, which includes fixes to get Netscape-1.2 running.
Calls to find_first_set_bit have been replaced with ffs.
ntohl, htonl, htons and ntohs were changed to be like the NetBSD versions (for little endian machines, of course).
e_linux_setup in i386/e_trampoline.c is only called if it's needed.
Added subcode handling for fpu traps in ns532/e_exception.c.
Updated ns532 sigcontext struct to correspond to NetBSD's.
Knows about the NetBSD-1.1 ``ffs'' mounttype.
Add some support for FreeBSD SIOCSIFMTU and SIOCSIFPHYS network ioctls.
