From: Wei Zhao Date: Wed, 29 Apr 2020 08:42:27 +0000 (+0800) Subject: net/ice/base: fix switch rule for IPsec X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=2e873cf407e8a7f0a2c4478eaa2c1d24c0d2fc74;p=dpdk.git net/ice/base: fix switch rule for IPsec When we download a switch rule for ipv6 with esp payload "eth / ipv6 / esp spi is 1 / end actions queue index 2 / end" if we don't add bm bit set check for tun_type, then a packet of ipv4 with esp payload "sendp([Ether(dst="00:00:00:00:01:00")/IP(proto=50)/ESP(spi=1)/ ("X"*480)], iface="ens5f0", count=10)" Will also go to queue index 2. And also, we need to do tun_type check, or the second rule of following can not be download because of rejection from switch rule download function ice_aq_sw_rules(). "eth / ipv4 / esp spi is 1 / end actions queue index 5 / end" "eth / ipv6 / esp spi is 1 / end actions queue index 2 / end" Fixes: 4f11962fce84 ("net/ice/base: support AH ESP and NAT-T on switch") Fixes: 99d8ba79efbe ("net/ice/base: force switch to use different recipe") Signed-off-by: Wei Zhao Tested-by: Qi Fu Acked-by: Qi Zhang --- diff --git a/drivers/net/ice/base/ice_switch.c b/drivers/net/ice/base/ice_switch.c index 957142a105..f3d52d2dc4 100644 --- a/drivers/net/ice/base/ice_switch.c +++ b/drivers/net/ice/base/ice_switch.c @@ -5285,10 +5285,7 @@ static u16 ice_find_recp(struct ice_hw *hw, struct ice_prot_lkup_ext *lkup_exts, /* If for "i"th recipe the found was never set to false * then it means we found our match */ - if (ice_is_prof_rule(tun_type) && - tun_type == recp[i].tun_type && found) - return i; /* Return the recipe ID */ - else if (!ice_is_prof_rule(tun_type) && found) + if (tun_type == recp[i].tun_type && found) return i; /* Return the recipe ID */ } } @@ -6005,9 +6002,11 @@ ice_get_compat_fv_bitmap(struct ice_hw *hw, struct ice_adv_rule_info *rinfo, prof_type = ICE_PROF_TUN_PPPOE; break; case ICE_SW_TUN_PROFID_IPV6_ESP: + case ICE_SW_TUN_IPV6_ESP: ice_set_bit(ICE_PROFID_IPV6_ESP, bm); return; case ICE_SW_TUN_PROFID_IPV6_AH: + case ICE_SW_TUN_IPV6_AH: ice_set_bit(ICE_PROFID_IPV6_AH, bm); return; case ICE_SW_TUN_PROFID_MAC_IPV6_L2TPV3: @@ -6036,6 +6035,12 @@ ice_get_compat_fv_bitmap(struct ice_hw *hw, struct ice_adv_rule_info *rinfo, case ICE_SW_TUN_IPV4_L2TPV3: ice_set_bit(ICE_PROFID_MAC_IPV4_L2TPV3, bm); return; + case ICE_SW_TUN_IPV4_ESP: + ice_set_bit(ICE_PROFID_IPV4_ESP, bm); + return; + case ICE_SW_TUN_IPV4_AH: + ice_set_bit(ICE_PROFID_IPV4_AH, bm); + return; case ICE_SW_TUN_AND_NON_TUN: default: prof_type = ICE_PROF_ALL; diff --git a/drivers/net/ice/base/ice_switch.h b/drivers/net/ice/base/ice_switch.h index 09dc1f2364..6bb742d2fd 100644 --- a/drivers/net/ice/base/ice_switch.h +++ b/drivers/net/ice/base/ice_switch.h @@ -16,7 +16,9 @@ #define ICE_FLTR_TX_RX (ICE_FLTR_RX | ICE_FLTR_TX) /* Switch Profile IDs for Profile related switch rules */ +#define ICE_PROFID_IPV4_ESP 71 #define ICE_PROFID_IPV6_ESP 72 +#define ICE_PROFID_IPV4_AH 73 #define ICE_PROFID_IPV6_AH 74 #define ICE_PROFID_IPV4_NAT_T 75 #define ICE_PROFID_IPV6_NAT_T 76
