jdolecek 638d27777e add linux_sys_truncate64() 2000-12-12 22:24:56 +00:00

jdolecek 405a6ce62f actually, we need to wrap sys_truncate() call so that the /emul/linux/...
path is tried first
fix ftruncate64 entry - first arg to ftruncate is int fd, not path

jdolecek 621dac5bc2 define struct linux_stat64 used by linux_sys_*stat64() 2000-12-12 19:07:59 +00:00

fvdl 0b7398458a Allow for passing through of certain ranges of ioctl command values
directly to a device. The device has to be aware of how to handle
with these special ioctls. Useful for LKMs that deal with Linux
binaries.

mycroft 455360f941 Do the __HAVE_SYSCALL_INTERN and __HAVE_MINIMAL_EMUL dance. 2000-12-12 08:00:26 +00:00
mycroft f495cd9dc6 Introduce 2 new flags in types.h:
* __HAVE_SYSCALL_INTERN.  If this is defined, e_syscall is replaced by
  e_syscall_intern, which is called at key places in the kernel.  This can be
  used to set a MD syscall handler pointer.  This obsoletes and replaces the
  *_HAS_SEPARATED_SYSCALL flags.
* __HAVE_MINIMAL_EMUL.  If this is defined, certain (deprecated) elements in
  struct emul are omitted.

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

erh f96aee80d6 Make the linux compatibilty code work on the alpha. (horay!) (at last!)
Two main changes:
	Create a linux_elf64_copyargs that uses the linux specific LinuxAuxInfo
	structure.  This is only used on the alpha.  i386 and m68k use the
	standard elf copyargs function.

	Since linux's approach to binary compatibilty is to look as much
	like osf1 as possible, add all the osf1 syscalls that we have
	implemented to the linux syscall table.  This includes get/setsysinfo,
	ported from FreeBSD.

In order for linux compat to work you must have COMPAT_OSF1, COMPAT_43,
COMPAT_09, COMPAT_12 and COMPAT_13 on also.

incomplete at the moment (notable the fp_control stuff) but they need to

linux compat are already here.

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.

jdolecek a777f280d1 fix obvious bug in svr4_sys_resolvepath():
since we have not requested locked vnode (LOCKLEAF is not used for namei()
call), the vnode is returned unlocked, so we need to use vrele(), not vput()

This fixes kern/11044.

thorpej 72a24b4eae Add an align argument to uvm_map() and some callers of that
routine.  Works similarly fto pmap_prefer(), but allows callers
to specify a minimum power-of-two alignment of the region.
How we ever got along without this for so long is beyond me.

fvdl 7f5724ad4c In the case of MAP_ANON, Linux mmap ignores the fd argument completely.
So, always pass -1 to the native syscall in that case, to avoid
errors if a Linux app doesn't specify -1 as the fd (which some do).

bouyer aacf1f7a6a Back out the suspendsched()/resumesched() thing, per request of Jason Thorpe &
Bill Sommerfeld. suspendsched() will be implemented in a different way.
2000-09-05 16:20:27 +00:00
bouyer 629150f864 Add the sched_suspend/sched_resume functions, as discussed on tech-kern,
with the following modifications to the initial patch:
- rename SHOLD and P_HOST to SSUSPEND and P_SUSPEND to avoid confusion with
  PHOLD()
- don't deal with SSUSPEND/P_SUSPEND in fork1(), if we come here while
  scheduler is suspended we're forking proc0, which can't have P_SUSPEND set.

sched_suspend() suspends the scheduling of users process, by removing all
processes from the run queues and changing their state from SRUN to
SSUSPEND. Also mark all user process but curproc P_SUSPEND.
When a process has to be put in SRUN and is marked P_SUSPEND, it's placed in
the SSUSPEND state instead.
sched_resume() places all SSUSPEND processes back in SRUN, clear the P_SUSPEND
flag.

sommerfeld 6b88a0fc51 Emulation stackgap sanity checks, based partly on fixes from
FreeBSD-SA00:42.

Change stackgap_alloc to bounds-check the allocation vs. the stack
gap, returning NULL if there isn't room for the allocation.

Change emul_find() to check for a NULL return from stackgap_alloc()
and convert that into ENAMETOOLONG.

Reorder various emulation syscalls so that all *_CHECK_ALT_{EXIST,CREAT}
calls (which turn into emul_find() under the covers come *after* small,
fixed-size stackgap_alloc() calls.

Clean up ibcs2 {get,set}groups.
