8cbefdbb89 Do address family (AF_*) number translation for socket system calls which
pass socket address in our or out. This makes Linux programs using IPv6
working under emulation. This addresses kern/13279 by Jun-ichiro itojun Hagino.

Change sendmsg()/recvmsg() to expect the control information
to be passed the standard way (not 4.3BSD one, imlied by compat_43 code
or MSG_COMPAT). Linux uses different (arguably broken) CMSG_ALIGN() on some
architectures unfortunately, that would need to be handled eventually.

Also provide some other trivial stubs (like linux_sys_send()) to avoid
unneeded dependance on uipc_syscalls_43.c.

7e7d262c34 Add %fs/%gs to trap frame and save/restore them on
trap/interrupt/syscall entry from userspace.

Remove special-case "by hand" validation of fs/gs register values as
well as special handling of them in various signal handling paths.

Now, like %ds and %es, they are validated by the hardware on return to
userland.

This paves the way for the use of %fs for per-cpu data on
multiprocessor systems, and fixes an otherwise difficult-to-fix
interaction between threads/clone(2) and USER_LDT.

Discussed in advance with Frank van der Linden.

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:

ce10f4da5b Linux does not send a SIGIO to the write end of a socket,
neither it does send any SIGIO for pipes. If async I/O
was requested, we keep the SS_ASYNC in struct socket flag
set, but we clear SB_ASYNC flags on the sending buffer
(for socket), and on the sending and the receiving buffer
(for pipes).

Because we do not alter to SS_ASYNC in struct socket,
the Linux process keeps a consistent view of async I/O
status if it attemps to read the async flag (SS_ASYNC)

This async I/O problem does matters, since some Linux
a programs such as the JDK request async I/O on pipes,
but they fail if they happen to get a SIGIO to the write
end of the pipe.

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.

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.

890850dddf Implement linux_sys_nosys() and use it instead of sys_nosys() for
unimplemented syscalls. Difference is that linux_sys_nosys() doesn't
post SIGSYS to the process. Linux doesn't do that and thus glibc (and
probably other Linux code) doesn't deal with SIGSYS, even through it
generally contains fallback code for ENOSYS case.

This also addresses port-i386/12503, though the issue was already discussed
earlier.

fvdl
b930296d07 Under Linux it's possible to return values through the ioctl system
call directly (i.e. not a reference argument, but a direct return
value). So far I have only seen this with binaries that talk
to their own device modules, using non-standard ioctl calls.
Hence, allow for a pass-through ioctl call using PTIOCLINUX to
return EJUSTRETURN, signalling that the return value is in
the 'data' field of the structure, which can then be put in 'retval'.

  - 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

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,

e03e9e8086 Rather than starting init and creating kthreads by forking and then
doing a cpu_set_kpc(), just pass the entry point and argument all
the way down the fork path starting with fork1().  In order to
avoid special-casing the normal fork in every cpu_fork(), MI code
passes down child_return() and the child process pointer explicitly.

This fixes a race condition on multiprocessor systems; a CPU could
grab the newly created processes (which has been placed on a run queue)
before cpu_set_kpc() would be performed.

78732e454b Remove conditionization upon XSERVER -- all the code
so conditionalized is already conditionalized on (NWSDISPLAY > 0),
so is wscons-specific. wscons has no conditionalization on XSERVER;
neither should the linux compatibility code.

Removing this is necessary to keep linux X server emulation functionining
after GENERIC rev 1.337 removing "options XSERVER" (relegating it
to the pccons/pcvt-specific, and therefore depricated).

7b918b4088 New callout mechanism with two major improvements over the old
timeout()/untimeout() API:
- Clients supply callout handle storage, thus eliminating problems of
  resource allocation.
- Insertion and removal of callouts is constant time, important as
  this facility is used quite a lot in the kernel.

The old timeout()/untimeout() API has been removed from the kernel.

600be45ffc Improve emulation of SIOCGIFHWADDR ioctl:
* when finding an interface, try the real name first before faking eth*
 * Linux kernel returns ENODEV if the request goes to unknown interface,
   so do the same here

This change makes Linux ICA client work.

c581bf97c5 A few things to make the Linux clone(2) emulation work a bit better:
- When the exit signal is specified to be 0, don't just assume they
  meant SIGCHLD.  In the Linux world, this appears to mean "don't deliver
  an exit signal at all".
- Simplify P_EXITSIG(); don't check against initproc here, just change
  the exit signal to SIGCHLD if reparenting to initproc.

A very simple clone(2) test program now works, and the MpegTV package
starts, but doesn't run properly yet (I believe there is a separate
bug which keeps it from working properly).
