b6168e0ca7 regen - 64 fs syscalls 2002-05-12 15:04:59 +00:00

0197718567 hook in remaining 64bit fs syscalls 
make most of stuff in linux_file64.c available unconditionally,
  with exception of fcntl64, which is not present on Linux m68k

187c2394f1 update for newer syscalls (from 2.5.15) 
Linux m68k doesn't seem to have fcntl64 syscall - oversight?

(revisions 1.47 & 1.48 effectively backed off):
* for all but vnodes, just fallback to sys_fcntl(); assumming
  state of support for F_SETOWN/F_GETOWN and even hardcoding it here is
  not right (e.g. rev. 1.47 had this incorrect for DTYPE_PIPE)
* fallback to sys_fcntl() also for vnodes which don't represent tty
* don't need to use FILE_{,UN}USE() here, the code won't block while
  using the pointer

- bug with order in args in mask conversion md code.
- flags can be both int and long on the alpha. kludge around that, by not
  passing pointers to the conversion function.
- something is wrong with the toolchain look at the void * cast in copyout().
- sa_restorer is in a different place on the aplha. Deal with that, by not
  initializing it as before. XXX: this should be changed in the MD signal

28debea38a - add a real linux_sys___sysctl because the mib numbers are different. 
implement only the kernel version getting entries.
- make the signal conversion functions consistent; dest is arg 1.
- make linux_fakedev deal with block and char devices differently.
- add linux_sys_ugetrlimit, and flesh out the regular get/setrlimit so
  that they work properly.
- add linux_mmap2 [untested].
- bump kernel to 2.4.18, and make the date be valentine's day :-)
- linux_sys_*stat64 family was totally busted. Fix it.

tested only on i386.

Status:
	gdb, telnet, work
	jdk-1.4.0 extractor works, jdk still coredumps.

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.

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.

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.

Async I/O OS specifities should now handled in OS specific code. Linux

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.
