thorpej 7b918b4088 New callout mechanism with two major improvements over the old
timeout()/untimeout() API:
- Clients supply callout handle storage, thus eliminating problems of
  resource allocation.
- Insertion and removal of callouts is constant time, important as
  this facility is used quite a lot in the kernel.

The old timeout()/untimeout() API has been removed from the kernel.

eeh a7474fcab6 netbsd32_close() would work better if it called sys_close() rather than
sys_write().
netbsd32_getfsstat() cannot just copyin()/copyout(), convert the structures,
and call sys_getffstat().  sys_getffstat() wants to do its own
copyin()/copyout().  So we need to implent the whole of sys_getffstat()
in netbsd32_getfsstat().

eeh a65e57bfc6 Update to 32-bit compatibility routines. 1999-12-30 15:40:45 +00:00
eeh 1f45477db9 Add netbsd32_compat_14.c
Rename everything from compat_netbsd32 -> netbsd32 so we don't have silly
names like compat_14_compat_netbsd32_sys_shmctl().

bouyer 52497e180a Remplace kern.shortcorename sysctl with a more flexible sheme,
core filename format, which allow to change the name of the core dump,
and to relocate it in a directory. Credits to Bill Sommerfeld for giving me
the idea :)
The default core filename format can be changed by options DEFCORENAME and/or
kern.defcorename
Create a new sysctl tree, proc, which holds per-process values (for now
the corename format, and resources limits). Process is designed by its pid
at the second level name. These values are inherited on fork, and the corename
fomat is reset to defcorename on suid/sgid exec.
Create a p_sugid() function, to take appropriate actions on suid/sgid
exec (for now set the P_SUGID flag and reset the per-proc corename).
Adjust dosetrlimit() to allow changing limits of one proc by another, with
credential controls.

thorpej eb20bbc780 Change the semantics of splsoftclock() to be like other spl*() functions,
that is priority is rasied.  Add a new spllowersoftclock() to provide the
atomic drop-to-softclock semantics that the old splsoftclock() provided,
and update calls accordingly.

This fixes a problem with using the "rnd" pseudo-device from within
interrupt context to extract random data (e.g. from within the softnet
interrupt) where doing so would incorrectly unblock interrupts (causing
all sorts of lossage).

XXX 4 platforms do not have priority-raising capability: newsmips, sparc,
XXX sparc64, and VAX.  This platforms still have this bug until their
XXX spl*() functions are fixed.

thorpej 32e1fd0d03 Move the call of cpu_wait() out of the wait4() functions, and into the
body of reaper(), right before the call to uvm_exit().  cpu_wait() must
be done before uvm_exit() because the resources it frees might be located
in the PCB.

kleink e79a283e47 XSH5: change function signature to `void *sbrk(intptr_t)'. 1999-07-12 21:55:19 +00:00
thorpej 12347b2657 Make uvm_vslock() return the error code from uvm_fault_wire(). All places
which use uvm_vslock() should now test the return value.  If it's not
KERN_SUCCESS, wiring the pages failed, so the operation which is using
uvm_vslock() should error out.

XXX We currently just EFAULT a failed uvm_vslock().  We may want to do
more about translating error codes in the future.

thorpej 497248ca55 XXX Pass VM_PROT_NONE to uvm_vslock() as access_type. Why are we even
vslocking here?!  copyout() on its own seems to suffice just about everwhere
else, and it's not like the process is going to exit; it's in a system
call!

thorpej e3669c3393 Add "use counting" to file entries. When closing a file, and it's reference
count is 0, wait for use count to drain before finishing the close.

This is necessary in order for multiple processes to safely share file
descriptor tables.
