4.8-stable review patch. If anyone has any objections, please let me know. ------------------ From: Anders K. Pedersen <akp@xxxxxxxxxxxx> commit a8b1e36d0d1d6f51490e7adce35367ed6adb10e7 upstream. With HZ=100 element timeout in dynamic sets (i.e. flow tables) is 10 times higher than configured. Add proper conversion to/from jiffies, when interacting with userspace. I tested this on Linux 4.8.1, and it applies cleanly to current nf and nf-next trees. Fixes: 22fe54d5fefc ("netfilter: nf_tables: add support for dynamic set updates") Signed-off-by: Anders K.
