This patch is fixing following issues : - commit 8fea3602 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 Signed-off-by: NArnaud Patard <arnaud.patard@rtp-net.org> Signed-off-by: NRiku Voipio <riku.voipio@iki.fi>

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".

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.

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...).

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.

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'.

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.
