netfilter: xtables: change xt_match.checkentry return type
Restore function signatures from bool to int so that we can report memory allocation failures or similar using -ENOMEM rather than always having to pass -EINVAL back. This semantic patch may not be too precise (checking for functions that use xt_mtchk_param rather than functions referenced by xt_match.checkentry), but reviewed, it produced the intended result. // <smpl> @@ type bool; identifier check, par; @@ -bool check +int check (struct xt_mtchk_param *par) { ... } // </smpl> Signed-off-by: Jan Engelhardt <jengelh@medozas.de>
