====================
net: filter: split sk_filter into socket and bpf, cleanup names
The main goal of the series is to split 'struct sk_filter' into socket and
bpf parts and cleanup names in the following way:
- everything that deals with sockets keeps 'sk_*' prefix
- everything that is pure BPF is changed to 'bpf_*' prefix
split 'struct sk_filter' into
struct sk_filter {
atomic_t refcnt;
struct rcu_head rcu;
struct bpf_prog *prog;
};
and
struct bpf_prog {
u32 jited:1,
len:31;
struct sock_fprog_kern *orig_prog;
unsigned int (*bpf_func)(const struct sk_buff *skb,
const struct bpf_insn *filter);
union {
struct sock_filter insns[0];
struct bpf_insn insnsi[0];
struct work_struct work;
};
};
so that 'struct bpf_prog' can be used independent of sockets and cleans up
'unattached' bpf use cases:
isdn, ppp, team, seccomp, ptp, xt_bpf, cls_bpf, test_bpf
which don't need refcnt/rcu fields.
It's a follow up to the rcu cleanup started by Pablo in
commit 34c5bd66e5 ("net: filter: don't release unattached filter through call_rcu()")
Patch 1 - cleans up socket memory charging and makes it possible for functions
sk(bpf)_migrate_filter(), sk(bpf)_prepare_filter() to be socket independent
Patches 2-4 - trivial renames
Patch 5 - sk_filter split and renames of related sk_*() functions
====================
