Instead of using ternary operator to set variable res, use the value
of variable match (or the negation) directly to simplify the code and

Indeed, symbols sdio_* are not present in kernel image.
This patch disallows CONFIG_WFX=y if CONFIG_MMC=m.
This solution impacts users who want to use SPI bus with configuration:
CONFIG_WFX=y + CONFIG_SPI=y + CONFIG_MMC=m. However, I think this is a

Since commit af4d768ad2 ("net/ipv4: Add support for specifying metric
of connected routes"), when updating an IP address with a different metric,
the associated connected route is updated, too.
Still, the mentioned commit doesn't handle properly some corner cases:
$ ip addr add dev eth0 192.168.1.0/24
$ ip addr add dev eth0 192.168.2.1/32 peer 192.168.2.2
$ ip addr add dev eth0 192.168.3.1/24
$ ip addr change dev eth0 192.168.1.0/24 metric 10
$ ip addr change dev eth0 192.168.2.1/32 peer 192.168.2.2 metric 10
$ ip addr change dev eth0 192.168.3.1/24 metric 10
$ ip -4 route
192.168.1.0/24 dev eth0 proto kernel scope link src 192.168.1.0
192.168.2.2 dev eth0 proto kernel scope link src 192.168.2.1
192.168.3.0/24 dev eth0 proto kernel scope link src 192.168.2.1 metric 10
Only the last route is correctly updated.
The problem is the current test in fib_modify_prefix_metric():
if (!(dev->flags & IFF_UP) ||
ifa->ifa_flags & (IFA_F_SECONDARY | IFA_F_NOPREFIXROUTE) ||
ipv4_is_zeronet(prefix) ||
prefix == ifa->ifa_local || ifa->ifa_prefixlen == 32)
Which should be the logical 'not' of the pre-existing test in
fib_add_ifaddr():
if (!ipv4_is_zeronet(prefix) && !(ifa->ifa_flags & IFA_F_SECONDARY) &&
(prefix != addr || ifa->ifa_prefixlen < 32))
To properly negate the original expression, we need to change the last
logical 'or' to a logical 'and'.

This is whats happening:
1. a conntrack entry is about to be confirmed (added to hash table).
2. a clash with existing entry is detected.
3. nf_ct_resolve_clash() puts skb->nfct (the "losing" entry).
4. this entry now has a refcount of 0 and is freed to SLAB_TYPESAFE_BY_RCU
kmem cache.
skb->nfct has been replaced by the one found in the hash.
Problem is that nf_conntrack_confirm() uses the old ct:
static inline int nf_conntrack_confirm(struct sk_buff *skb)
{
struct nf_conn *ct = (struct nf_conn *)skb_nfct(skb);
int ret = NF_ACCEPT;

if (!nf_ct_is_confirmed(ct))
ret = __nf_conntrack_confirm(skb);
if (likely(ret == NF_ACCEPT))
nf_ct_deliver_cached_events(ct); /* This ct has refcount 0! */
}
return ret;
}
As of "netfilter: conntrack: free extension area immediately", we can't
access conntrack extensions in this case.
To fix this, make sure we check the dying bit presence before attempting
to get the eache extension.
