backout part of execsw/LKM changes: netbsd_elf32_signature() is used by
...
the compat/netbsd32 code so de-static it again.

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.

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

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

add ddb commands "show uvmexp" and "show ncache".

the former used to be "call uvm_dump", the latter is new.

change cache_purgevfs() from O(N^2) to O(N).

use queue.h macros where possible.
2000-11-24 05:02:23 +00:00
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.

ifdef DEBUG, increase the max size we'll overwrite in freed memory blocks

to detect modifications after frees from 32 bytes to 1 page.

Add a LOCKDEBUG check for a r/w spinlock spinning out of control.

Partially from Bill Sommerfeld.

Unlock mutex before jumping off from the critical region instead of

testing if locked.

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

disable the LM_EXEC stuff for now, it doesn't work anyway

this will be fixed 'soon'

Allow machine dependent code to specify a hook to be run when a

spinlock's interlock is released.
Idea from Bill Sommerfeld.

simple_lock_held is only defined when you use LOCKDEBUG.
...
Put it for now in an ifdef LOCKDEBUG.

Add a sysctl_rdminstruct() function - same as sysctl_rdstruct() but

can return short data if *oldlenp is less than len.

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

If MULTIPROCESSOR, count cpus and use that for hw.ncpu
2000-11-19 01:46:26 +00:00

Preliminary MULTIPROCESSOR support:
...
- for CP_TIME, sum the times across all processors.
- for kinfo_proc2, fill in cpu_id.

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

Don't use alloca() - breaks compile on alpha (alloca is not prototyped
...
anywhere).

pass pointer to used exec_package to emulation-specific exec hook -

emulation code may make decisions based on e.g. exec format

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)
2000-11-14 20:05:28 +00:00

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

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

write KTR_EMUL entry on end of fork1() - primarily usable when the new

process never does execve(2), such as when creating a thread

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
