christos 7218f10c3c sort the ioctl's so we can see what we've implemented and what we have not. 2003-05-07 14:21:20 +00:00
dsl 60418b39b7 Change 'data' argument to fo_ioctl and fo_fcntl from 'caddr_t' to 'void *'.
Avoids a lot of casting and removes the need for some line breaks.
Removed a load of (caddr_t) casts from calls to copyin/copyout as well.
(approved by christos - he has a plan to remove caddr_t...)

atatat bede65472d Cull unused variables. Sigh.
PS - Cross compilers are cool.

atatat 59b8237f5e No need to pick a "default address" for mmap in compat code, since we
merely call sys_mmap() at the end anyway, and that will pick the
address for us, if it's needed.

Likewise for checking if /dev/zero is being mapped.

manu 80ee637534 - Introduce a e_fault field in struct proc to provide emulation specific
memory fault handler. IRIX uses irix_vm_fault, and all other emulation
use NULL, which means to use uvm_fault.

- While we are there, explicitely set to NULL the uninitialized fields in
struct emul: e_fault and e_sysctl on most ports

- e_fault is used by the trap handler, for now only on mips. In order to avoid
intrusive modifications in UVM, the function pointed by e_fault does not
has exactly the same protoype as uvm_fault:
int uvm_fault __P((struct vm_map *, vaddr_t, vm_fault_t, vm_prot_t));
int e_fault __P((struct proc *, vaddr_t, vm_fault_t, vm_prot_t));

- In IRIX share groups, all the VM space is shared, except one page.
This bounds us to have different VM spaces and synchronize modifications
to the VM space accross share group members. We need an IRIX specific hook
to the page fault handler in order to propagate VM space modifications
caused by page faults.

gehenna 77a6b82b27 Merge the gehenna-devsw branch into the trunk.
This merge changes the device switch tables from static array to
dynamically generated by config(8).

- All device switches is defined as a constant structure in device drivers.

- The new grammer ``device-major'' is introduced to ``files''.

	device-major <prefix> char <num> [block <num>] [<rules>]

- All device major numbers must be listed up in port dependent majors.<arch>
  by using this grammer.

- Added the new naming convention.
  The name of the device switch must be <prefix>_[bc]devsw for auto-generation
  of device switch tables.

- The backward compatibility of loading block/character device
  switch by LKM framework is broken. This is necessary to convert
  from block/character device major to device name in runtime and vice versa.

- The restriction to assign device major by LKM is completely removed.
  We don't need to reserve LKM entries for dynamic loading of device switch.

- In compile time, device major numbers list is packed into the kernel and
  the LKM framework will refer it to assign device major number dynamically.

thorpej 011d4d5f44 Add kernel support for having userland provide the signal trampoline:
* struct sigacts gets a new sigact_sigdesc structure, which has the
  sigaction and the trampoline/version.  Version 0 means "legacy kernel
  provided trampoline".  Other versions are coordinated with machine-
  dependent code in libc.
* sigaction1() grows two more arguments -- the trampoline pointer and
  the trampoline version.
* A new __sigaction_sigtramp() system call is provided to register a
  trampoline along with a signal handler.
* The handler is no longer passed to sensig() functions.  Instead,
  sendsig() looks up the handler by peeking in the sigacts for the
  process getting the signal (since it has to look in there for the
  trampoline anyway).
* Native sendsig() functions now select the appropriate trampoline and
  its arguments based on the trampoline version in the sigacts.

Changes to libc to use the new facility will be checked in later.  Kernel
version not bumped; we will ride the 1.6C bump made recently.

christos 7c50f65a84 get rid of STACKGAP* shit. 2002-03-16 23:55:57 +00:00
christos 381e6a7764 make the stackgap_{init,alloc} functions MP friendly (i.e. pass struct proc *
in, instead of using curproc). While there add an optional size argument to
stackgap_init.

jdolecek ef8abe0767 Make the setregs hook emulation-specific, rather than executable
format specific.
Struct emul has a e_setregs hook back, which points to emulation-specific
setregs function. es_setregs of struct execsw now only points to
optional executable-specific setup function (this is only used for
ECOFF).

thorpej 80cc38a1af Fix a partial construction problem that can cause race conditions
between creation of a file descriptor and close(2) when using kernel
assisted threads.  What we do is stick descriptors in the table, but
mark them as "larval".  This causes essentially everything to treat
it as a non-existent descriptor, except for fdalloc(), which sees a
filled slot so that it won't (incorrectly) allocate it again.  When
a descriptor is fully constructed, the code that has constructed it
marks it as "mature" (which actually clears the "larval" flag), and
things continue to work as normal.

While here, gather all the code that gets a descriptor from the table
into a fd_getfile() function, and call it, rather than having the
same (sometimes incorrect) code copied all over the place.

jdolecek 01040d97a2 add e_path (emulation path) to struct emul, which replaces emulation-specific
*_emul_path variables

change macros CHECK_ALT_{CREAT|EXIST} to use that, 'root' doesn't need
to be passed explicitly any more and *_CHECK_ALT_{CREAT|EXIST} are removed
change explicit emul_find() calls in probe functions to get the emulation
path from the checked exec switch entry's emulation

remove no longer needed header files

add e_flags and e_syscall to struct emul; these are unsed and empty for now

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

simonb 3c359c262d The size of the members of struct ultrix_utsname were nothing like
reality - adjust and fill in "version" the same way that some other
compat routines do.  An Ultrix "uname -a" returns something meaninful
now instead of just "NetBSD     ".

kleink 230876cf26 Merge parts of chs-ubc2 into the trunk:
* Remove the casts to vaddr_t from the round_page() and trunc_page() macros to
  make them type-generic, which is necessary i.e. to operate on file offsets
  without truncating them.
* In due course, cast pointer arguments to these macros to an appropriate
  integral type (paddr_t, vaddr_t).

Originally done by Chuck Silvers, updated by myself.
