hw/9pfs: fix P9_STATS_GEN handling

Currently we fail getattr request altogether if we can't read
P9_STATS_GEN for some reason. It breaks valid use cases:

E.g let's assume we have non-readable directory with execution bit set
on host and we export it to client over 9p On host we can chdir into...

hw/9pfs: make get_st_gen() return ENOTTY error on special files

Currently we silently ignore getversion requests for anything except
file or directory. Let's instead return ENOTTY error to indicate that
getversion is not supported. It makes implementation consistent on...

hw/9pfs: handle undefined FS_IOC_GETVERSION case in handle_ioc_getversion()

All get_st_gen() implementations except handle_ioc_getversion() have
guard for undefined FS_IOC_GETVERSION. Let's add it there too.

hw/9pfs: fix error handing in local_ioc_getversion()

v9fs_co_st_gen() expects to see error code in errno, not in return code.

Let's fix this.

hw/9pfs: Fix errno value for xattr functions

If there is no operation driver for the xattr type the
functions return '-1' and set errno to '-EOPNOTSUPP'.
When the calling code sets 'ret = -errno' this turns
into a large positive number.

In Linux 3.11, the kernel has switched to using 9p...

virtio-9p-device: Avoid freeing uninitialized memory

In virtio_9p_device_init() there are 6x goto out that will lead to
v9fs_path_free() attempting to free unitialized path.data field.
Easiest way to trigger is: qemu-system-x86_64 -device virtio-9p-pci

Fix this by moving v9fs_path_init() before any goto out....

hw/9pfs: Fix potential memory leak and avoid reuse of freed memory

The leak was reported by cppcheck.

Function proxy_init also calls g_free for ctx->fs_root.
Avoid reuse of this memory by setting ctx->fs_root to NULL.
