| | | | | | | | | | | | | | Merge the contents (less some trivial bordering the silly comments) of <vm/vm_prot.h> and <vm/vm_inherit.h> into <vm/vm.h>. This puts the #defines for the vm_inherit_t and vm_prot_t types next to their typedefs. This paves the road for the commit to follow shortly: change useracc() to use VM_PROT_{READ|WRITE} rather than B_{READ|WRITE} as argument. Notes: svn path=/head/; revision=52635
* sigset_t change (part 4 of 5)Marcel Moolenaar1999-09-291-7/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ----------------------------- The compatibility code and/or emulators have been updated: iBCS2 now mostly uses the older syscalls. SVR4 now properly handles all signals. This has been achieved by using the new sigset_t throughout the emulator. The Linuxulator has been severely updated. Internally the new Linux sigset_t is made the default. These are then mapped to and from the new FreeBSD sigset_t. Also, rt_sigsuspend has been implemented in the Linuxulator. Implementing this syscall basicly caused all this sigset_t changing in the first place and the syscall has been used throughout the change as a means for testing. It basicly is too much work to undo the implementation so that it can later be added again. A special note on the use of sv_sigtbl and sv_sigsize in struct sysentvec: Every signal larger than sv_sigsize is not translated and is passed on to the signal handler unmodified. Signals in the range 1 upto and including sv_sigsize are translated. The rationale is that only the system defined signals need to be translated. The emulators also have been updated so that the translation tables are only indexed for valid (system defined) signals. This change also fixes the translation bug already in the SVR4 emulator.

* Add sysctl variables for the Linuxulator. These reside under `compat.linux' asMarcel Moolenaar1999-08-271-3/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | egid will be twice in the set and that setting cr_groups[0] will change egid. This is simply solved by ignoring cr_groups[0].
