2016-09-17tcp: prepare skbs for better sack shiftingEric Dumazet
With large BDP TCP flows and lossy networks, it is very important to keep a low number of skbs in the write queue. RACK and SACK processing can perform a linear scan of it. We should avoid putting any payload in skb->head, so that SACK shifting can be done if needed. With this patch, we allow to pack ~0.5 MB per skb instead of the 64KB initially cooked at tcp_sendmsg() time. This gives a reduction of number of skbs in write queue by eight. tcp_rack_detect_loss() likes this. We still allow payload in skb->head for first skb put in the queue, to not impact RPC workloads.

2016-09-17net: avoid sk_forward_alloc overflowsEric Dumazet
A malicious TCP receiver, sending SACK, can force the sender to split skbs in write queue and increase its memory usage. Then, when socket is closed and its write queue purged, we might overflow sk_forward_alloc (It becomes negative) sk_mem_reclaim() does nothing in this case, and more than 2GB are leaked from TCP perspective (tcp_memory_allocated is not changed) Then warnings trigger from inet_sock_destruct() and sk_stream_kill_queues() seeing a not zero sk_forward_alloc All TCP stack can be stuck because TCP is under memory pressure. A simple fix is to preemptively reclaim from sk_mem_uncharge(). This makes sure a socket wont have more than 2 MB forward allocated, after burst and idle period.

2016-09-17tcp: fix overflow in __tcp_retransmit_skb()Eric Dumazet

2016-09-17xen-netback: fix error handling on netback_probe()Filipe Manco
In case of error during netback_probe() (e.g. an entry missing on the xenstore) netback_remove() is called on the new device, which will set the device backend state to XenbusStateClosed by calling set_backend_state(). However, the backend state wasn't initialized by netback_probe() at this point, which will cause and invalid transaction and set_backend_state() to BUG(). Initialize the backend state at the beginning of netback_probe() to XenbusStateInitialising, and create two new valid state transitions on set_backend_state(), from XenbusStateInitialising to XenbusStateClosed, and from XenbusStateInitialising to XenbusStateInitWait.

Tariq Toukan says: ==================== mlx5e Order-0 pages for Striding RQ In this series, we refactor our Striding RQ receive-flow to always use fragmented WQEs (Work Queue Elements) using order-0 pages, omitting the flow that allocates and splits high-order pages which would fragment and deplete high-order pages in the system. The first patch gives a slight degradation, but opens the opportunity to using a simple page-cache mechanism of a fair size. The page-cache, implemented in patch 3, not only closes the performance gap but even gives a gain. In patch 2 we re-organize the code to better manage the calls for alloc/de-alloc pages in the RX flow.

2016-09-17net/mlx5e: Single flow order-0 pages for Striding RQTariq Toukan
To improve the memory consumption scheme, we omit the flow that demands and splits high-order pages in Striding RQ, and stay with a single Striding RQ flow that uses order-0 pages. Moving to fragmented memory allows the use of larger MPWQEs, which reduces the number of UMR posts and filler CQEs. Moving to a single flow allows several optimizations that improve performance, especially in production servers where we would anyway fallback to order-0 allocations: - inline functions that were called via function pointers. - improve the UMR post process. This patch alone is expected to give a slight performance reduction. However, the new memory scheme gives the possibility to use a page-cache of a fair size, that doesn't inflate the memory footprint, which will dramatically fix the reduction and even give a performance gain. Performance tests: The following results were measured on a freshly booted system, giving optimal baseline performance, as high-order pages are yet to be fragmented and depleted.

2016-09-17rxrpc: Improve skb tracingDavid Howells
Improve sk_buff tracing within AF_RXRPC by the following means: (1) Use an enum to note the event type rather than plain integers and use an array of event names rather than a big multi ?: list. (2) Distinguish Rx from Tx packets and account them separately. This requires the call phase to be tracked so that we know what we might find in rxtx_buffer[]. (3) Add a parameter to rxrpc_{new,see,get,free}_skb() to indicate the event type. (4) A pair of 'rotate' events are added to indicate packets that are about to be rotated out of the Rx and Tx windows. (5) A pair of 'lost' events are added, along with rxrpc_lose_skb() for packet loss injection recording. Signed-off-by: David Howells <dhowells@redhat.com>

2016-09-17rxrpc: Fix the basic transmit DATA packet content size at 1412 bytesDavid Howells
Fix the basic transmit DATA packet content size at 1412 bytes so that they can be arbitrarily assembled into jumbo packets. In the future, I'm thinking of moving to keeping a jumbo packet header at the beginning of each packet in the Tx queue and creating the packet header on the spot when kernel_sendmsg() is invoked. That way, jumbo packets can be assembled on the spur of the moment for (re-)transmission. Signed-off-by: David Howells <dhowells@redhat.com>
2016-09-17rxrpc: Be consistent about switch value in rxrpc_send_call_packet()David Howells

2016-09-17rxrpc: Fix retransmission algorithmDavid Howells
Make the retransmission algorithm use for-loops instead of do-loops and move the counter increments into the for-statement increment slots. Though the do-loops are slighly more efficient since there will be at least one pass through the each loop, the counter increments are harder to get right as the continue-statements skip them. Without this, if there are any positive acks within the loop, the do-loop will cycle forever because the counter increment is never done. Signed-off-by: David Howells <dhowells@redhat.com>
2016-09-17rxrpc: Fix the parsing of soft-ACKsDavid Howells
The soft-ACK parser doesn't increment the pointer into the soft-ACK list, resulting in the first ACK/NACK value being applied to all the relevant packets in the Tx queue. This has the potential to miss retransmissions and cause excessive retransmissions. Fix this by incrementing the pointer. Signed-off-by: David Howells <dhowells@redhat.com>
2016-09-17rxrpc: Fix unexposed client conn releaseDavid Howells
If the last call on a client connection is release after the connection has had a bunch of calls allocated but before any DATA packets are sent (so that it's not yet marked RXRPC_CONN_EXPOSED), an assertion will happen in rxrpc_disconnect_client_call(). af_rxrpc: Assertion failed - 1(0x1) >= 2(0x2) is false ------------[ cut here ]------------ kernel BUG at ../net/rxrpc/conn_client.c:753! This is because it's expecting the conn to have been exposed and to have 2 or more refs - but this isn't necessarily the case. Simply remove the assertion. This allows the conn to be moved into the inactive state and deleted if it isn't resurrected before the final put is called. Signed-off-by: David Howells <dhowells@redhat.com>
2016-09-17rxrpc: Call rxrpc_release_call() on error in rxrpc_new_client_call()David Howells
Call rxrpc_release_call() on getting an error in rxrpc_new_client_call() rather than trying to do the cleanup ourselves. This isn't a problem, provided we set RXRPC_CALL_HAS_USERID only if we actually add the call to the calls tree as cleanup code fragments that would otherwise cause problems are conditional. Without this, we miss some of the cleanup. Signed-off-by: David Howells <dhowells@redhat.com>
2016-09-17rxrpc: Fix the putting of client connectionsDavid Howells
In rxrpc_put_one_client_conn(), if a connection has RXRPC_CONN_COUNTED set on it, then it's accounted for in rxrpc_nr_client_conns and may be on various lists - and this is cleaned up correctly. However, if the connection doesn't have RXRPC_CONN_COUNTED set on it, then the put routine returns rather than just skipping the extra bit of cleanup. Fix this by making the extra bit of clean up conditional instead and always killing off the connection. This manifests itself as connections with a zero usage count hanging around in /proc/net/rxrpc_conns because the connection allocated, but discarded, due to a race with another process that set up a parallel connection, which was then shared instead.

2016-09-17rxrpc: Fix handling of the last packet in rxrpc_recvmsg_data()David Howells
The code for determining the last packet in rxrpc_recvmsg_data() has been using the RXRPC_CALL_RX_LAST flag to determine if the rx_top pointer points to the last packet or not. This isn't a good idea, however, as the input code may be running simultaneously on another CPU and that sets the flag *before* updating the top pointer. Fix this by the following means: (1) Restrict the use of RXRPC_CALL_RX_LAST to the input routines only. There's otherwise a synchronisation problem between detecting the flag and checking tx_top. This could probably be dealt with by appropriate application of memory barriers, but there's a simpler way. (2) Set RXRPC_CALL_RX_LAST after setting rx_top. (3) Make rxrpc_rotate_rx_window() consult the flags header field of the DATA packet it's about to discard to see if that was the last packet. Use this as the basis for ending the Rx phase. This shouldn't be a problem because the recvmsg side of things is guaranteed to see the packets in order. (4) Make rxrpc_recvmsg_data() return 1 to indicate the end of the data if: (a) the packet it has just processed is marked as RXRPC_LAST_PACKET (b) the call's Rx phase has been ended.
