I tried to group recovery related fields nearby (non-CA_Open related variables, to be more accurate) so that one to three cachelines would not be necessary in CA_Open. These are now contiguously deployed: struct sk_buff_head out_of_order_queue; /* 1968 80 */ /* --- cacheline 32 boundary (2048 bytes) --- */ struct tcp_sack_block duplicate_sack[1]; /* 2048 8 */ struct tcp_sack_block selective_acks[4]; /* 2056 32 */ struct tcp_sack_block recv_sack_cache[4]; /* 2088 32 */ /* --- cacheline 33 boundary (2112 bytes) was 8 bytes ago --- */ struct sk_buff * highest_sack; /* 2120 8 */ int lost_cnt_hint; /* 2128 4 */ int retransmit_cnt_hint; /* 2132 4 */ u32 lost_retrans_low; /* 2136 4 */ u8 reordering; /* 2140 1 */ u8 keepalive_probes; /* 2141 1 */ /* XXX 2 bytes hole, try to pack */ u32 prior_ssthresh; /* 2144 4 */ u32 high_seq; /* 2148 4 */ u32 retrans_stamp; /* 2152 4 */ u32 undo_marker; /* 2156 4 */ int undo_retrans; /* 2160 4 */ u32 total_retrans; /* 2164 4 */ ...and they're then followed by URG slowpath & keepalive related variables. Head of the out_of_order_queue always needed for empty checks, if that's empty (and TCP is in CA_Open), following ~200 bytes (in 64-bit) shouldn't be necessary for anything. If only OFO queue exists but TCP is in CA_Open, selective_acks (and possibly duplicate_sack) are necessary besides the out_of_order_queue but the rest of the block again shouldn't be (ie., the other direction had losses). As the cacheline boundaries depend on many factors in the preceeding stuff, trying to align considering them doesn't make too much sense. Commented one ordering hazard. There are number of low utilized u8/16s that could be combined get 2 bytes less in total so that the hole could be made to vanish (includes at least ecn_flags, urg_data, urg_mode, frto_counter, nonagle).

The purpose of nla_parse_nested_compat() is to parse attributes which contain a struct followed by a stream of nested attributes. So far, it called nla_parse_nested() to parse the stream of nested attributes which was wrong, as nla_parse_nested() expects a container attribute as data which holds the attribute stream. It needs to call nla_parse() directly while pointing at the next possible alignment point after the struct in the beginning of the attribute. With this patch, I can no longer reproduce the reported leftover warnings. Signed-off-by:

Add a "follow" selection for fail_over_mac. This option causes the MAC address to move from slave to slave as the active slave changes. This is in addition to the existing fail_over_mac option that causes the bond's MAC address to change during failover. This new option is useful for devices that cannot tolerate multiple ports using the same MAC address simultaneously, either because it confuses them or incurs a performance penalty (as is the case with some LPAR-aware multiport devices). Because the MAC of the bond itself does not change, the "follow" option is slightly more reliable during failover and doesn't change the MAC of the bond during operation. This patch requires a previous ARP monitor change to properly handle RTNL during failovers. Signed-off-by:

Refactor ARP monitor for active-backup mode. The motivation for this is to take care of locking issues in a clear manner (particularly to correctly handle RTNL vs. the bonding locks). Currently, the a-b ARP monitor does not hold RTNL at all, but future changes will require RTNL during ARP monitor failovers. Rather than using conditional locking, this patch instead breaks up the ARP monitor into three discrete steps: inspection, commit changes, and probe. The inspection phase marks slaves that require link state changes. The commit phase is only called if inspection detects that changes are needed, and is called with RTNL. Lastly, the probe phase issues the ARP probes that the inspection phase uses to determine link state. Signed-off-by:

With IPoIB, reception of gratuitous ARP by neighboring hosts is essential for a successful change of slaves in case of failure. Otherwise, they won't learn about the HW address change and need to wait a long time until the neighboring system gives up and sends an ARP request to learn the new HW address. This patch decreases the chance for a lost of a gratuitous ARP packet by sending it more than once. The number retries is configurable and can be set with a module param. Signed-off-by:
