netfilter: nf_conntrack: restrict runtime expect hashsize modifications
Expectation hashtable size was simply glued to a variable with no code to rehash expectations, so it was a bug to allow writing to it. Make "expect_hashsize" readonly. Signed-off-by: Alexey Dobriyan <adobriyan@gmail.com> Cc: stable@kernel.org Signed-off-by: Patrick McHardy <kaber@trash.net>
