mrg af640de164 move the COMPAT_SUNOS SO_BROADCAST hack out of uipc_socket.c into the
compat/sunos code.  besides being cleaner this allows the sunos LKM
to properly work without any special kernel hacks.
2002-01-03 00:59:00 +00:00
tsutsui 1011f9fbcc Don't define COMPAT_SUNOS here. It is defined in opt_compat_sunos.h
and <sys/ioctl.h> and <sys/tty.h> include it properly.

XXX Is this needed for LKM?

thorpej e8ee04475d - Add a new vnode flag VEXECMAP, which indicates that a vnode has
executable mappings.  Stop overloading VTEXT for this purpose (VTEXT
  also has another meaning).
- Rename vn_marktext() to vn_markexec(), and use it when executable
  mappings of a vnode are established.
- In places where we want to set VTEXT, set it in v_flag directly, rather
  than making a function call to do this (it no longer makes sense to
  use a function call, since we no longer overload VTEXT with VEXECMAP's
  meaning).

VEXECMAP suggested by Chuq Silvers.

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).

christos 0f380fac15 Add an e_trapsignal member to struct emul, so that emulated processes can
send the appropriate signal depending on the trap type.

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:

                                  Net Free Open Linux SunOS AIX OSF1 Darwin

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.

fvdl 6b7a7448f5 Cast 32bit sunos_nfs_arg member to (char *)(long) to avoid warning
after sunos.h change (cast is safe; a SunOS binary will pas a 32 bit
pointer).

mrg bdec681975 sunos_ioctl.c is included by sunos32_ioctl.c. include the sunos32 &
netbsd32 headers if we are in sunos32 mode.

thorpej 1b6a66420e Regen; add sy_flags. 2001-01-27 07:23:06 +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.
2000-12-11 05:28:59 +00:00
jdolecek a6ca890142 always fill in e_syscall in respective emul_*; if the emulation doesn't
have it's own separated *_syscall() function, use syscall()

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

SunOS binaries needs to test this...
2000-11-24 10:21:30 +00:00
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

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.
