2013-10-15ipvs: avoid rcu_barrier during netns cleanupJulian Anastasov4-7/+9
commit 578bc3ef1e473a ("ipvs: reorganize dest trash") added rcu_barrier() on cleanup to wait dest users and schedulers like LBLC and LBLCR to put their last dest reference. Using rcu_barrier with many namespaces is problematic. Trying to fix it by freeing dest with kfree_rcu is not a solution, RCU callbacks can run in parallel and execution order is random. Fix it by creating new function ip_vs_dest_put_and_free() which is heavier than ip_vs_dest_put(). We will use it just for schedulers like LBLC, LBLCR that can delay their dest release. By default, dests reference is above 0 if they are present in service and it is 0 when deleted but still in trash list. Change the dest trash code to use ip_vs_dest_put_and_free(), so that refcnt -1 can be used for freeing. As result, such checks remain in slow path and the rcu_barrier() from netns cleanup can be removed. Signed-off-by: Julian Anastasov <ja@ssi.bg> Signed-off-by: Simon Horman <horms@verge.net.au>

2013-10-10inet: rename ir_loc_port to ir_numEric Dumazet11-19/+19
In commit 634fb979e8f ("inet: includes a sock_common in request_sock") I forgot that the two ports in sock_common do not have same byte order : skc_dport is __be16 (network order), but skc_num is __u16 (host order) So sparse complains because ir_loc_port (mapped into skc_num) is considered as __u16 while it should be __be16 Let rename ir_loc_port to ireq->ir_num (analogy with inet->inet_num), and perform appropriate htons/ntohs conversions.

This change brings support for 64 bit netstats to the driver. Previously the stats were 64 bit but highly racy due to the fact that 64 bit transactions are not atomic on 32 bit systems.

2013-10-09i40e: Move rings from pointer to array to array of pointersAlexander Duyck6-185/+204
Allocate the queue pairs individually instead of as a group. This allows for much easier queue management as it is possible to dynamically resize the queues without having to free and allocate the entire block. Ease statistic collection by treating Tx/Rx queue pairs as a single unit. Each pair is allocated together and starts with a Tx queue and ends with an Rx queue. By ordering them this way it is possible to know the Rx offset based on a pointer to the Tx queue.

2013-10-09i40e: Split bytes and packets from Rx/Tx statsAlexander Duyck5-26/+28
This makes it so that the Tx and Rx byte and packet counts are separated from the rest of the statistics. This allows for better isolation of these stats when we move them into the 64 bit statistics. Simplify things by re-ordering how the stats display in ethtool. Instead of displaying all of the Tx queues as a block, followed by all the Rx queues, the new order is Tx[0], Rx[0], Tx[1], Rx[1], ..., Tx[n], Rx[n]. This reduces the loops and cleans up the display for testing purposes since it is very easy to verify if flow director is doing the right thing as the Tx and Rx queue pair are shown in pairs.

2013-10-09i40e: Do not directly increment Tx next_to_useAlexander Duyck1-21/+25
Avoid directly incrementing next_to_use for multiple reasons. The main reason being that if we directly increment it then it can attain a state where it is equal to the ring count. Technically this is a state it should not be able to reach but the way this is written it now can. This patch pulls the value off into a register and then increments it and writes back either the value or 0 depending on if the value is equal to the ring count.

2013-10-10net: gro: allow to build full sized skbEric Dumazet1-17/+26
skb_gro_receive() is currently limited to 16 or 17 MSS per GRO skb, typically 24616 bytes, because it fills up to MAX_SKB_FRAGS frags. It's relatively easy to extend the skb using frag_list to allow more frags to be appended into the last sk_buff. This still builds very efficient skbs, and allows reaching 45 MSS per skb. (45 MSS GRO packet uses one skb plus a frag_list containing 2 additional sk_buff) High speed TCP flows benefit from this extension by lowering TCP stack cpu usage (less packets stored in receive queue, less ACK packets processed) Forwarding setups could be hurt, as such skbs will need to be linearized, although its not a new problem, as GRO could already provide skbs with a frag_list. We could make the 65536 bytes threshold a tunable to mitigate this. (First time we need to linearize skb in skb_needs_linearize(), we could lower the tunable to ~16*1460 so that following skb_gro_receive() calls build smaller skbs) Signed-off-by: Eric Dumazet <edumazet@google.com> Signed-off-by: David S.

2013-10-09ipv6: make lookups simpler and fasterEric Dumazet35-288/+213
TCP listener refactoring, part 4 : To speed up inet lookups, we moved IPv4 addresses from inet to struct sock_common Now is time to do the same for IPv6, because it permits us to have fast lookups for all kind of sockets, including upcoming SYN_RECV. Getting IPv6 addresses in TCP lookups currently requires two extra cache lines, plus a dereference (and memory stall). inet6_sk(sk) does the dereference of inet_sk(__sk)->pinet6 This patch is way bigger than its IPv4 counter part, because for IPv4, we could add aliases (inet_daddr, inet_rcv_saddr), while on IPv6, it's not doable easily. inet6_sk(sk)->daddr becomes sk->sk_v6_daddr inet6_sk(sk)->rcv_saddr becomes sk->sk_v6_rcv_saddr And timewait socket also have tw->tw_v6_daddr & tw->tw_v6_rcv_saddr at the same offset.

2013-10-08tcp/dccp: remove twchainEric Dumazet12-261/+132
TCP listener refactoring, part 3 : Our goal is to hash SYN_RECV sockets into main ehash for fast lookup, and parallel SYN processing. Current inet_ehash_bucket contains two chains, one for ESTABLISH (and friend states) sockets, another for TIME_WAIT sockets only. As the hash table is sized to get at most one socket per bucket, it makes little sense to have separate twchain, as it makes the lookup slightly more complicated, and doubles hash table memory usage. If we make sure all socket types have the lookup keys at the same offsets, we can use a generic and faster lookup. It turns out TIME_WAIT and ESTABLISHED sockets already have common lookup fields for IPv4. [ INET_TW_MATCH() is no longer needed ] I'll provide a follow-up to factorize IPv6 lookup as well, to remove INET6_TW_MATCH() This way, SYN_RECV pseudo sockets will be supported the same. A new sock_gen_put() helper is added, doing either a sock_put() or inet_twsk_put() [ and will support SYN_RECV later ]. Note this helper should only be called in real slow path, when rcu lookup found a socket that was moved to another identity (freed/reused immediately), but could eventually be used in other contexts, like sock_edemux() Before patch : dmesg | grep "TCP established" TCP established hash table entries: 524288 (order: 11, 8388608 bytes) After patch : TCP established hash table entries: 524288 (order: 10, 4194304 bytes) Signed-off-by: Eric Dumazet <edumazet@google.com> Signed-off-by: David S.

2013-10-08ipv6: Fix the upper MTU limit in GRE tunnelOussama Ghorbel1-2/+1
Unlike ipv4, the struct member hlen holds the length of the GRE and ipv6 headers. This length is also counted in dev->hard_header_len. Perhaps, it's more clean to modify the hlen to count only the GRE header without ipv6 header as the variable name suggest, but the simple way to fix this without regression risk is simply modify the calculation of the limit in ip6gre_tunnel_change_mtu function.
