Check for NUL termination within the buffer we have.
>From Ilja Van Sprundel.
Make sure we have enough space in the buffer before reading it.
>From Ilja Van Sprundel.
Make sure we move forward over the buffer.
>From Ilja Van Sprundel.
Zero buffers in ibcs2 ioctl to avoid disclosing stack to userland.
>From Ilja Van Sprundel.
Don't drop vnode ref until we're done with mount in ibcs2_stat(v)fs.
Nothing else guarantees the mount will stick around.
>From Ilja Van Sprundel.
Little happy on the commit trigger.  Actually use the out label.
