2009-06-16Return EOPNOTSUPP instead of ENOSYS for *xattr* syscallsArnaud Patard1-1/+2
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 Signed-off-by: Arnaud Patard <arnaud.patard@rtp-net.org> Signed-off-by: Riku Voipio <riku.voipio@iki.fi>
2009-06-16Fix struct termios host - target translationArnaud Patard1-0/+2
When converting the termios structure between host and target in target_to_host_termios and host_to_target_termios, the c_cc[] array is never initialised. Calling memset() before using it allows to run successfully "stty echo / stty -echo" on arm-linux-user target (host being x86 and mips).

2009-06-16linux-user: fix utimensatRiku Voipio1-14/+24
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. Add configure check for older systems Signed-off-by: Riku Voipio <riku.voipio@iki.fi>

2009-06-04fix gdbstub support for multiple threads in usermode, v3Nathan Froyd1-1/+3
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.

2009-04-21MIPS signal handling fixes.pbrook3-4/+109
Also fixes a register corruption bug in do_sigreturn. When "returning" from sigreturn we are actually restoring the virtual cpu state from the signal frame. This is actually surprisingly hard to observe in practice. Typically an thread be blocked in a FUTEX_WAIT call when the signal arrives, so the effect is a spurious syscall success and the introduction of a subtle race condition. On x86/arm a syscall modifies a single word sized register, so do_sigreturn can just return that value. On MIPS a syscall clobbers multiple registers, so we need additional smarts. My solution is to invent a magic errno value that means "don't touch CPU state". git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@7194 c046a42c-6fe2-441c-8c8c-71466251a162

The patch called "prefer glibc over direct syscalls" (commit 7118) has replaced the getcwd syscall with a call to the glibc. With this change, the syscall is returning -1 in error case and 0 otherwise. This is problematic as the sys_getcwd syscall should return the number of bytes written to the buffer including the '\0'.

2009-04-15linux-user: proper exit code for uncaught signalsaurel321-12/+25
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.

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.

2009-04-08linux-user: fix problems with inotify syscallsaurel321-3/+3
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.
