jdolecek c9710a72e0 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.

XXX sligh code rearrangement was necessary, change not tested

Also tweak the darwin siginfo stuff to avoid the same type of collision.

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.

christos 830c5c171a Implement passing AT_{E,R}{U,G}ID in the elf aux vector, like solaris.
- pass struct proc to copyargs.
- eliminate svr4_copyargs, since it is the same as ours now.

jdolecek d08f6c6e2e pull <sys/exec.h> to get setregs prototype.
problem noted by Chuck Silvers
2001-09-23 19:32:10 +00:00
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).

dmcmahill 1880c09133 regen after adding flock. 2001-06-23 02:46:25 +00:00
dmcmahill b2ddb9701f Add entry for flock() syscall.
From the NetBSD and OSF man pages, the arguments and operation of the
2 flocks are identical.  The only differences are in some of the possible
values for errno which may be set in the event of certain errors.  These
differences are (again from the manual pages):

The NetBSD flock may set errno to

     [EOPNOTSUPP]  The argument fd refers to an object other than a file.

and the OSF flock doesn't list this is a possible error code.

The OSF flock may set errno to:

  [EINTR]   A signal interuppted the flock call.
  [ENOLCK]  The lock table is full.  Too many regions are already locked.
  [EDEADLK] The lock is blocked by some lock from another process.  Putting
            the calling process to sleep while waiting for that lock to
            become free would cause a deadlock.

while the NetBSD flock does not list these as possibilities.

The remainder of the possible error codes are the same.

commit cleared with thorpej first.

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.

manu 7e6929fe90 Changed EMUL_BSD_ASYNCIO_PIPE to EMUL_NO_BSD_ASYNCIO_PIPE, so that
the native emulation (NetBSD) does not have a flag.
2001-05-07 09:55:12 +00:00
manu 5a6b8191b5 Added two flags to emulation packages:
EMUL_BSD_ASYNCIO_PIPE notes that the emulated binaries expect the original
BSD pipe behavior for asynchronous I/O, which is to fire SIGIO on read() and
write(). OSes without this flag do not expect any SIGIO to be fired on
read() and write() for pipes, even when async I/O was requested. As far as
we know, the OSes that need EMUL_BSD_ASYNCIO_PIPE are NetBSD, OSF/1 and
Darwin.

EMUL_NO_SIGIO_ON_READ notes that the emulated binaries that requested
asynchrnous I/O expect the reader process to be notified by a SIGIO, but
not the writer process. OSes without this flag expect the reader and the
writer to be notified when some data has arrived or when some data have been
read. As far as we know, the OSes that need EMUL_NO_SIGIO_ON_READ are Linux
and SunOS.

jdolecek b6d1d4db02 Change the first arg to fileops fo_stat routine to struct file *, adjust
callers and appropriate routines to cope. This makes fo_stat more
consistent with rest of fileops routines and also makes the fo_stat
match FreeBSD as an added bonus.
Discussed with Luke Mewburn on tech-kern@.

ross 2d8e2c19d6 Fix soo_stat() calls for the new parameter, even if the direct call is
now obsolete, so that kernels will at least compile. I guess it was too
much trouble to change all 10 call sites, or perhaps, these days, only
things that build on i386 are important. Maybe it's the full moon tonight.

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.
