917507b01e linux-user: check some parameters for some socket syscalls.
This patch is fixing following issues :

- commit 8fea36025b was applied to
  do_getsockname instead of do_accept.
- Some syscalls were not checking properly the memory addresses passed
  as argument
- Add check before syscalls made for cases like do_getpeername() where
  we're using the address parameter after doing the syscall
- Fix do_accept to return EINVAL instead of EFAULT when parameters
  invalid to match with linux behaviour

3f9ac9b39b linux-user: remove duplicate tswap32() from do_getsockopt()
This issue has been detected with tests/linux-tests.c:

linux-test.c:330: getsockopt

327     len = sizeof(val);
328     chk_error(getsockopt(server_fd, SOL_SOCKET, SO_TYPE, &val, &len));
329     if (val != SOCK_STREAM)
330         error("getsockopt");

In linux-user/syscall.c:do_getsockopt(), we have:
...
        val = tswap32(val);
...
            if (put_user_u32(val, optval_addr))
...

whereas "put_user_u32" calls in the end "__put_user" which uses "tswap32".

So the "val = tswap32(val);" is useless and wrong.

This patch removes it.

5f10681186 RFC: fix fcntl support in linux-user - new try
Hi,

This is a new try to fix the fcntl support in linux-user. I tried to
adress all comments but as the previous version is several weeks old,
it's possible that I've missed some.

This patch doesn't handle linux specific fcntl flags. My plan is to get
this version of the patch reviewed/fixed and then, add them if wanted.

Thanks,
Arnaud

6f932f9172 Return EOPNOTSUPP instead of ENOSYS for *xattr* syscalls
In current code, we're sending ENOSYS to target when a syscall for the
xattrs is done. This makes applications like ls complain loudly about
that and breaks scripts parsing the output. Moreover, iirc, implemented
features of filesystems are are sending EOPNOTSUPP (I've not checked so
I may be a little bit wrong on that...).
So, I'm proposing to return -EOPNOTSUPP and make ls happy

ebc996f3b1 linux-user: fix utimensat
The glibc function for utimensat glibc returns -EINVAL when the path is null
which is a different behaviour with the syscall.

path can be null because internally the glibc is using utimensat with
path null when implmenting futimens. If path is null, call futimes
instead.

don't try to copy timespec from user if is NULL.

1e9fa73016 fix gdbstub support for multiple threads in usermode, v3
When debugging multi-threaded programs, QEMU's gdb stub would report the
correct number of threads (the qfThreadInfo and qsThreadInfo packets).
However, the stub was unable to actually switch between threads (the T
packet), since it would report every thread except the first as being
dead.  Furthermore, the stub relied upon cpu_index as a reliable means
of assigning IDs to the threads.  This was a bad idea; if you have this
sequence of events:

initial thread created
new thread #1
new thread #2
thread #1 exits
new thread #3

thread #3 will have the same cpu_index as thread #1, which would confuse
GDB.  (This problem is partly due to the remote protocol not having a
good way to send thread creation/destruction events.)

We fix this by using the host thread ID for the identifier passed to GDB
when debugging a multi-threaded userspace program.  The thread ID might
wrap, but the same sort of problems with wrapping thread IDs would come
up with debugging programs natively, so this doesn't represent a
problem.

dbfe4c3611 linux-user: fix problems with inotify syscalls
The sys_inotify* calls are defined if the target supports them and the
host supports the necessary syscalls.  But the syscalls are handled if
the target supports them.  This situation leads to compilation failures
when the host doesn't support the necessary syscalls, as the linker will
complain about undefined functions.

Fix this state of affairs by making the handling conditions the same as
the call definition conditions.
