rafal efdd3f2dd7 There is no linux_sys_ugetrlimit on mips, so don't try building it (XXX: adds
icky ifdefs)
2002-02-17 23:56:35 +00:00
rafal dfcb814799 Use linux_sys_{g,s}etrlimit() since there's a common implementation now; but
MIPS has no sys_ugetrlimit, so don't declare it (209 is UNIMPL in the OSS
Linux-mips tree)

christos 51ea9c87e7 proper comment. 2002-02-15 16:50:13 +00:00
christos 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.

bjh21 8a3c27fbf7 Add support for the ARM-specific syscalls in ARMLinux. These are invoked
by SWI numbers above 0x9f0000, but we re-map them down to somewhere just
after the end of the usual syscall range, since NetBSD doesn't handle
sparse syscall arrays well.

The only syscall I've actually implemented in this range is cacheflush(),
which was previously being mapped to fork(), causing ... interesting results.

to be the value of emul_linux.e_syscall that we want.  This allows it to differ

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.

manu 948a7fa8ef Fixed some mistakes in signal handling (this is still broken)

manu a9c8120ff3 Fixes my last commit: only mips really need fcntl64 to work now. i386 and
powerpc could use it later if needed. m68k and alpha should never need it.

martin 62aaf2691e Make i386 kernels compile again.
fcntl64 was still marked UNIMPL, but the implementation existed, causing

please review it!

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 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.

sommerfeld 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.

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
send SIGIO to write end of pipe		Y  N    N     N     N    N   Y     Y
send SIGIO to read end of pipe      Y  Y    N     N     N    ?   Y     ?

send SIGIO to read end of socket    Y  Y    Y     Y     Y    ?   Y     ?
2001-06-16 21:44:27 +00:00
manu 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.

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.

be a pointer to data, which holds the result. Linux's glibc undo this odd
operation to bring the standard ptrace behavior to userland.

manu 23e3fc1231 When c_ospeed in termio is null, NetBSD hangup the terminal. Since Linux

that NetBSD does not hangup.

manu d473f5bd8a Improved the accuracy of gettimeofday/settimeofday: Linux stores a srtuct
timezone in the kernel. We now keep track of it for emulated processes.
Tested for powerpc and i386. Untested on m68k, but it should be ok
Alpha has a particular implementation (osf1_sys_gettimeofday), and it has
therefore not been touched.

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.
