2009-04-15linux-user: fix warnings introduced by r7118aurel32
Signed-off-by: Aurelien Jarno <aurelien@aurel32.net> git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@7120 c046a42c-6fe2-441c-8c8c-71466251a162
2009-04-15linux-user: proper exit code for uncaught signalsaurel32
The proper exit code for dieing from an uncaught signal is -<signal>. The kernel doesn't allow exit() or _exit() to pass a negative value. To get the proper exit code we need to actually die from an uncaught signal. A default signal handler is installed, we send ourself a signal and we wait for it to arrive.

2009-04-15linux-user: prefer glibc over direct syscallsaurel32
The openat/*at syscalls are incredibly common with modern coreutils, calling them directly via syscalls breaks for example fakeroot. Use glibc stubs whenever directly available and provide old syscall calling for people still using older libc.

2009-04-15linux-user: removed unnecessary MAX_SOCK_ADDR checks for socket syscallsaurel32

2009-04-15linux-user: unix sockets - fix running dbusaurel32
dbus sends too short (according to man 7 unix) addrlen for it's unix socket. I've been told that happens with other applications as well. Linux kernel doesn't appear to mind, so I guess we whould be tolerant as well. Expand sockaddr with +1 to fit the \0 of the pathname passed. (scratchbox1 qemu had a very different workaround for the same issue).

2009-04-08linux-user: fix problems with inotify syscallsaurel32
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.
