nisimura 10571faa84 Introduce uvm_km_valloc_align() and use it to glab process's USPACE
aligned on USPACE boundary in kernel virutal address.  It's benefitial
for MIPS R4000's paired TLB entry design.

takemura 3c9d9276dc Add new powerhook argument values, PWR_SOFTSUSPEND, PWR_SOFTSTANDBY and
PWR_SOFTRESUME. Apm calls powerhook with the values in normal interrupt
priority level while others are protected with splhigh().
2000-11-26 11:08:57 +00:00
jdolecek d9a0883770 define COMPAT_OLDSOCK unconditionally - the code is used virtually for all
emulations besides NetBSD, and this way it's LKM-safe
2000-11-24 21:38:28 +00:00
chs 55a751c9d5 add ddb commands "show uvmexp" and "show ncache".
the former used to be "call uvm_dump", the latter is new.
2000-11-24 07:25:50 +00:00
chs ab077e1ed4 change cache_purgevfs() from O(N^2) to O(N).
use queue.h macros where possible.
2000-11-24 05:02:23 +00:00
chs fa19fe52db adjust the spinlock macros in the non-MULTIPROCESSOR, non-LOCKDEBUG case
so that gcc will think that static spinlock are used.
this allows us to remove the ugly conditionalization of
static spinlock declarations.
2000-11-24 03:59:07 +00:00
chs 22d140fd0b ifdef DEBUG, increase the max size we'll overwrite in freed memory blocks
to detect modifications after frees from 32 bytes to 1 page.

thorpej 113dd58233 Add a LOCKDEBUG check for a r/w spinlock spinning out of control.
Partially from Bill Sommerfeld.
2000-11-22 06:31:22 +00:00
itojun 6c7e531e99 make COMPAT_OSF1 to compile. not tested (could someone review?). 2000-11-22 03:48:33 +00:00
enami 29f1bcd8e2 Unlock mutex before jumping off from the critical region instead of
testing if locked.
2000-11-21 03:53:27 +00:00
jdolecek baae0324b9 restructure struct emul and execsw, in preparation to make emulations LKMable:
* move all exec-type specific information from struct emul to execsw[] and
  provide single struct emul per emulation
* elf:
  - kern/exec_elf32.c:probe_funcs[] is gone, execsw[] how has one entry
    per emulation and contains pointer to respective probe function
  - interp is allocated via MALLOC() rather than on stack
  - elf_args structure is allocated via MALLOC() rather than malloc()
* ecoff: the per-emulation hooks moved from alpha and mips specific code
  to OSF1 and Ultrix compat code as appropriate, execsw[] has one entry per
  emulation supporting ecoff with appropriate probe function
* the makecmds/probe functions don't set emulation, pointer to emulation is
  part of appropriate execsw[] entry
* constify couple of structures

jdolecek e5b244c609 disable the LM_EXEC stuff for now, it doesn't work anyway
this will be fixed 'soon'
2000-11-21 00:11:38 +00:00
thorpej 3075dec01a Allow machine dependent code to specify a hook to be run when a
spinlock's interlock is released.

Idea from Bill Sommerfeld.
2000-11-20 20:04:49 +00:00
veego a174b8a595 simple_lock_held is only defined when you use LOCKDEBUG.
Put it for now in an ifdef LOCKDEBUG.
2000-11-20 06:36:02 +00:00
simonb f104ee65be Add a sysctl_rdminstruct() function - same as sysctl_rdstruct() but
can return short data if *oldlenp is less than len.
2000-11-20 01:46:56 +00:00
jdolecek 26fe6166ed check_pty(): simple_unlock() might have been called even if the lock was
not locked previously in some cases; unlock only if the lock is held

sommerfeld 0cc75528c8 If MULTIPROCESSOR, count cpus and use that for hw.ncpu 2000-11-19 01:46:26 +00:00
sommerfeld 89b4aa9918 Preliminary MULTIPROCESSOR support:
- for CP_TIME, sum the times across all processors.
 - for kinfo_proc2, fill in cpu_id.
2000-11-19 01:34:58 +00:00
sommerfeld f276315e1c In pool_setlowat(), only call pool_catchup() if the pool is under the
low water mark.  (Avoids annoying warning when you setlowat a static
pool).
2000-11-19 00:29:51 +00:00
simonb 3f9e6ed0b8 Don't use alloca() - breaks compile on alpha (alloca is not prototyped
anywhere).
2000-11-18 15:58:13 +00:00
jdolecek 4ba9d75b97 pass pointer to used exec_package to emulation-specific exec hook -
emulation code may make decisions based on e.g. exec format

thorpej b7d004daa6 Use round_page() instead of roundup(..., NBPG). 2000-11-14 22:13:20 +00:00
itojun 68f0fe3840 make sure every m_aux will be freed.
there are direct use of MFREE() from sys/kern.
(we experienced no memory leak so far, but if we use m_aux for other purposes,
we will need this change)

jdolecek 78b866e95a change the type of *syscallnames[] array to 'const char * const foo[]' 2000-11-13 21:32:15 +00:00

structure

ad 642267bcc7 Update for hashinit() change. 2000-11-08 14:28:12 +00:00
ad 5fcf59fd7c Allow for creation of both LIST and TAILQ based hashes by adding a `hash
type' argument to hashinit().
2000-11-08 14:25:23 +00:00
chs ff1e758c8c use round_page(...) instead of roundup(..., NBPG). 2000-11-08 05:53:10 +00:00
chs a74393b970 remove unneeded includes. 2000-11-08 05:47:56 +00:00
chs a284236c04 in fork1(), only add make the new proc visible (by giving it a pid
and adding it to allproc) after it's fully initialized.
this prevents the scheduler from coming in via a clock interrupt
and tripping over a partially-initialized proc.
2000-11-08 05:16:23 +00:00
jdolecek 7d8eefdffc add void *p_emuldata into struct proc - this can be used to hold per-process
emulation-specific data
add process exit, exec and fork function hooks into struct emul:
* e_proc_fork() - called in fork1() after the new forked process is setup
* e_proc_exec() - called in sys_execve() after the executed process is setup
* e_proc_exit() - called in exit1() after all the other process cleanups are
  done, right before machine-dependant switch to new context; also called
  for "old" emulation from sys_execve() if emulation of executed program and
  the original process is different

This was discussed on tech-kern.
2000-11-07 12:41:52 +00:00
jdolecek 75823fcfc2 write KTR_EMUL entry on end of fork1() - primarily usable when the new
process never does execve(2), such as when creating a thread

tv c6a1ef4f70 8 spaces -> tab 2000-11-05 22:41:35 +00:00
jdolecek e8e4da6b87 add new function sigismasked(), which checks whether passed signal
is ignored or masked by the process, and use it appropriately
instead of directly checking p->p_sigmask and p->p_sigignore
2000-11-05 15:37:09 +00:00
enami 08810e4e74 Make this file compile again. 2000-11-02 06:57:01 +00:00
eeh d85adca51f Make line disciplines modular so they can be added or removed dynamically. 2000-11-01 23:51:38 +00:00
he a08889417a Use an rlim_t to store "available memory", so we don't needlessly
overflow and/or sign extend.

christos 0628f0a87e knf [from charles] 2000-10-17 23:38:55 +00:00
christos 23c15f1578 Don't set P_SUGID if the calls to set{e,}{u,g}id(), setreuid(),
setgroups() did not result in actual changes. This has the nice
side effect that we don't needlesly allocate new credential and
resource limit data structures.

This is so that non setuid programs that call seteuid(getuid()),
don't end up setting P_SUGID, resulting in broken behavior [i.e.
non setuid ssh, doesn't read ~/.hostaliases...].

This is a good candidate for a pullup, if someone reviews it.

itojun da566268df attach ARP domain only if INET is compiled into the kernel. 2000-10-02 04:27:21 +00:00
ad 50cf734d26 (*minphys)() musn't return zero. 2000-09-29 13:27:12 +00:00
eeh 1ecf6779be Add support for variable end of user stacks needed to support COMPAT_NETBSD32:
`struct vmspace' has a new field `vm_minsaddr' which is the user TOS.

	PS_STRINGS is deprecated in favor of curproc->p_pstr which is derived
	from `vm_minsaddr'.

	Bump the kernel version number.
