netns: fix double free at netns creation
This patch fix a double free when a network namespace fails. The previous code does a kfree of the net_generic structure when one of the init subsystem initialization fails. The 'setup_net' function does kfree(ng) and returns an error. The caller, 'copy_net_ns', call net_free on error, and this one calls kfree(net->gen), making this pointer freed twice. This patch make the code symetric, the net_alloc does the net_generic allocation and the net_free frees the net_generic. Signed-off-by: Daniel Lezcano <daniel.lezcano@free.fr> Signed-off-by: David S.
