The root cause of this is that skb_hash will call the -flow_dissector. At this point the skb still contains the magic switch -header and the skb->protocol field is not set up to the correct 802.3 -value yet. By the time the tag specific code is called, removing the header -and =roperly setting the protocol an invalid hash is already set. In the -case of the mt7530 this will result in all flows always having the same -hash. - -This patch makes the flow dissector honour the nh and protocol offset -defined by the dsa tag driver thus fixing dissection, hashing and RPS. - -Signed-off-by: John Crispin <john@phrozen.org> ---- - net/core/flow_dissector.c | 14 +++++++++++++- - 1 file changed, 13 insertions(+), 1 deletion(-) - ---- a/net/core/flow_dissector.c -+++ b/net/core/flow_dissector.c -@@ -4,6 +4,7 @@ - #include <linux/ip.h> - #include <linux/ipv6.h> - #include <linux/if_vlan.h> -+#include <net/dsa.h> - #include <net/ip.h> - #include <net/ipv6.h> - #include <net/gre.h> -@@ -123,13 +124,23 @@ bool __skb_flow_dissect(const struct sk_ - bool skip_vlan = false; - u8 ip_proto = 0; - bool ret; -- - if (!data) { - data = skb->data; - proto = skb_vlan_tag_present(skb) ? - skb->vlan_proto : skb->protocol; - nhoff = skb_network_offset(skb); - hlen = skb_headlen(skb); -+ if (unlikely(netdev_uses_dsa(skb->dev))) { -+ const struct dsa_device_ops *ops; -+ int offset; -+ -+ ops = skb->dev->dsa_ptr->tag_ops; -+ if (ops->flow_dissect && -+ !ops->flow_dissect(skb, &proto, &offset)) { -+ hlen -= offset; -+ nhoff += offset; -+ } -+ } - } - - /* It is ensured by skb_flow_dissector_init() that control key will -@@ -162,6 +173,7 @@ again: - case htons(ETH_P_IP): { - const struct iphdr *iph; - struct iphdr _iph; -+ - ip: - iph = __skb_header_pointer(skb, nhoff, sizeof(_iph), data, hlen, &_iph); - if (!iph || iph->ihl < 5) |
