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.

jdolecek 47cd9b85d6 Get the dynamic interpreter location using emul_find_interp(), so that
it checks both the alternative/emul tree, and the non-emul tree.
This makes it possible to run chrooted emulated binaries without need
to setup shadow /emul tree within the chroot hierarchy.
Only tested for COMPAT_LINUX, changes to other compat modules were
mechanical.
Fixes kern/19161 by Christian Groessler.

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.

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.

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).

jdolecek 26d45c1101 Back off the sendit()/recvit() change, some have problems with it 2001-06-25 20:46:11 +00:00
jdolecek 7f7c60e827 Add 'kernsa' parameter for sendit()/recvit(); if nonzero, msg->msg_name
is supposed to point directly to struct mbuf or struct sockaddr in kernel
space as appropriate, rather than being a pointer to memory in userland.

This is to be used by compat/* when emulation needs to wrap
send{to|msg}(2)/recv{from|msg}(2) and modify the passed struct
sockaddr.

manu a7cdf998ec Removed obsoletes EMUL_NO_BSD_ASYNCIO_PIPE and EMUL_NO_SIGIO_ON_READ flags.
Async I/O OS specifities should now handled in OS specific code. Linux
has been done, but other emulation should be handled. See case LINUX_F_SETFL
in sys/compat/linux/common/linux_file.c:linux_sys_fcntl() for more details.

The data that has been collected yet:

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.
