* opt_kstack_pages.h is not needed anymore. It would have been a Bad ThingPeter Wemm2002-09-081-2/+1
| | | | | | | if it had been different to the running kernel. Notes: svn path=/head/; revision=103089
* Unbreak the modules build:Thomas Moestl2002-09-071-1/+2
| | | | | | | | | | | | - 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.

* Introduce support for Mandatory Access Control and extensibleRobert Watson2002-08-011-1/+2
| | | | | | | | | | | | | | | 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.

* Pass maintainership over to emulation@FreeBSD.org. It has been fun,Marcel Moolenaar2001-11-181-1/+1
| | | | | | | | | | | 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! Notes: svn path=/head/; revision=86538
* Round of cleanups and enhancements. These include (in random order):Marcel Moolenaar2001-09-081-5/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. Notes: svn path=/head/; revision=83221

* Retire linux(8). Using shell scripts to load kernel loadable modules isSheldon Hearn2000-11-023-74/+0
| | | | | | | | | | | | | | | | | out of fashion. This particular case, unlike joy(8) and friends which are just plain silly, did more than just load a kernel loadable module. However, /etc/rc and the linux_base port were adjusted a while back to cope with the absence of this script. The only outstanding reason to hang on to it would have been for the linux(8) manual page, which clued folks into the existence of the Linuxulator. A new linux(4) was introduced a while back. It does a much better job. This script just isn't useful any more. Notes: svn path=/head/; revision=68243

* Pull in sys/conf/kmod.mk, rather than /usr/share/mk/bsd.kmod.mk.Peter Wemm2000-05-041-1/+1
| | | | | | | | | | This means that the kernel can be totally self contained now and is not dependent on the last buildworld to update /usr/share/mk.

* Add sysctl variables for the Linuxulator. These reside under `compat.linux' asMarcel Moolenaar1999-08-271-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | discussed on current. The following variables are defined (for now): osname (defaults to "Linux") Allow users to change the name of the OS as returned by uname(2), specially added for all those Linux Netscape users and statistics maniacs :-) We now have what we all wanted! osrelease (defaults to "2.2.5") Allow users to change the version of the OS as returned by uname(2). Since -current supports glibc2.1 now, change the default to 2.2.5 (was 2.0.36). oss_version (defaults to 198144 [0x030600]) This one will be used by the OSS_GETVERSION ioctl (PR 12917) which I can commit now that we have the MIB. The default version number is the lowest version possible with the current 'encoding'. A note about imprisoned processes (see jail(2)): These variables are copy-on-write (as suggested by phk). This means that imprisoned processes will use the system wide value unless it is written/set by the process. From that moment on, a copy local to the prison will be used. A note about the implementation: I choose to add a single pointer to struct prison, because I didn't like the idea of changing struct prison every time I come up with a new variable. As a side effect, the extra storage is only needed when a variable is set from within the prison. This also minimizes kernel bloat when the Linuxulator is not used; both compiled in or as a module.
