Title
smb: client: fix oops due to uninitialised var in smb2_unlink()
Summary
In the Linux kernel, the following vulnerability has been resolved: smb: client: fix oops due to uninitialised var in smb2_unlink() If SMB2_open_init() or SMB2_close_init() fails (e.g. reconnect), the iovs set @rqst will be left uninitialised, hence calling SMB2_open_free(), SMB2_close_free() or smb2_set_related() on them will oops. Fix this by initialising @close_iov and @open_iov before setting them in @rqst.
