2016-11-239pfs: add cleanup operation in FileOperationsLi Qiang1-0/+1
Currently, the backend of VirtFS doesn't have a cleanup function. This will lead resource leak issues if the backed driver allocates resources. This patch addresses this issue.

2016-10-179pfs: allocate space for guest originated empty stringsLi Qiang1-1/+1
If a guest sends an empty string paramater to any 9P operation, the current code unmarshals it into a V9fsString equal to { .size = 0, .data = NULL }. This is unfortunate because it can cause NULL pointer dereference to happen at various locations in the 9pfs code. And we don't want to check str->data everywhere we pass it to strcmp() or any other function which expects a dereferenceable pointer. This patch enforces the allocation of genuine C empty strings instead, so callers don't have to bother. Out of all v9fs_iov_vunmarshal() users, only v9fs_xattrwalk() checks if the returned string is empty. It now uses v9fs_string_size() since name.data cannot be NULL anymore.

2016-09-169pfs: drop useless v9fs_string_null() functionGreg Kurz2-6/+0
The v9fs_string_null() function just calls v9fs_string_free(). Also it only has 4 users, whereas v9fs_string_free() has 87. This patch converts users to call directly v9fs_string_free() and drops the useless function. Signed-off-by: Greg Kurz <groug@kaod.org> Reviewed-by: Cédric Le Goater <clg@kaod.org>
