o Remove @- from the ln and change it to a -sf. This was bogus, and

regocnized as such at the time. Now that the other bogons in the tree have been fixed, we can remove this ugly kludge. o Remove stale/bogus opt_foo.h files. These are left over from by-gone resources. And they point to the need, yet again, to improve the build system so meta information is only in one place.

opt_kstack_pages.h is not needed anymore. It would have been a Bad Thing

Unbreak the modules build:

- add dependencies on opt_cpu.h and opt_kstack_pages.h to the linux module Makefile in the i386 case. The latter is needed by an i386-only file, the former by the i386 implementation of linux_sysvec.c (opt_cpu.h is used for architecture-dependent options, so I added it only for i386, although this file is also generated for the alpha). - add a dependency on opt_kstack_pages.h to the pecoff module Makefile.

kernel access control. Invoke appropriate MAC entry points for a number of VFS-related operations in the Linux ABI module. In particular, handle uselib in a manner similar to open() (more work is probably needed here), as well as handle statfs(), and linux readdir()-like calls.

but time and other interests is making it hard. Open the door for new blood and fresh tactics now that the Linuxulator has had its facelift. Thanks to all who contributed during my tour of duty!

Round of cleanups and enhancements. These include (in random order):

2001-09-08T19:07:04Z

o Introduce private types for use in linux syscalls for two reasons: 1. establish type independence for ease in porting and, 2. provide a visual queue as to which syscalls have proper prototypes to further cleanup the i386/alpha split. Linuxulator types are prefixed by 'l_'. void and char have not been "virtualized". o Provide dummy functions for all syscalls and remove dummy functions or implementations of truely obsolete syscalls. o Sanitize the shm*, sem* and msg* syscalls. o Make a first attempt to implement the linux_sysctl syscall. At this time it only returns one MIB (KERN_VERSION), but most importantly, it tells us when we need to add additional sysctls :-) o Bump the kenel version up to 2.4.2 (this is not the same as the KERN_VERSION MIB, BTW). o Implement new syscalls, of which most are specific to i386. Our syscall table is now up to date with Linux 2.4.2. Some highlights: - Implement the 32-bit uid_t and gid_t bases syscalls. - Implement a couple of 64-bit file size/offset bases syscalls. o Fix or improve numerous syscalls and prototypes. o Reduce style(9) violations while I'm here. Especially indentation inconsistencies within the same file are addressed. Re-indenting did not obfuscate actual changes to the extend that it could not be combined. NOTE: I spend some time testing these changes and found that if there were regressions, they were not caused by these changes AFAICT. It was observed that installing a RH 7.1 runtime environment did make matters worse. Hangs and/or reboots have been observed with and without these changes, so when it failed to make life better in cases it doesn't look like it made it worse.
