2017-08-06tcp: fix cwnd undo in Reno and HTCP congestion controlsYuchung Cheng1-1/+1
Using ssthresh to revert cwnd is less reliable when ssthresh is bounded to 2 packets. This patch uses an existing variable in TCP "prior_cwnd" that snapshots the cwnd right before entering fast recovery and RTO recovery in Reno. This fixes the issue discussed in netdev thread: "A buggy behavior for Linux TCP Reno and HTCP" https://www.spinics.net/lists/netdev/msg444955.html Suggested-by: Neal Cardwell <ncardwell@google.com> Reported-by: Wei Sun <unlcsewsun@gmail.com> Signed-off-by: Yuchung Cheng <ncardwell@google.com> Signed-off-by: Neal Cardwell <ncardwell@google.com> Signed-off-by: David S.

2017-08-06phylink: add phylink infrastructureRussell King2-0/+147
The link between the ethernet MAC and its PHY has become more complex as the interface evolves. This is especially true with serdes links, where the part of the PHY is effectively integrated into the MAC. Serdes links can be connected to a variety of devices, including SFF modules soldered down onto the board with the MAC, a SFP cage with a hotpluggable SFP module which may contain a PHY or directly modulate the serdes signals onto optical media with or without a PHY, or even a classical PHY connection. Moreover, the negotiation information on serdes links comes in two varieties - SGMII mode, where the PHY provides its speed/duplex/flow control information to the MAC, and 1000base-X mode where both ends exchange their abilities and each resolve the link capabilities. This means we need a more flexible means to support these arrangements, particularly with the hotpluggable nature of SFP, where the PHY can be attached or detached after the network device has been brought up. Ethtool information can come from multiple sources: - we may have a PHY operating in either SGMII or 1000base-X mode, in which case we take ethtool/mii data directly from the PHY. - we may have a optical SFP module without a PHY, with the MAC operating in 1000base-X mode - the ethtool/mii data needs to come from the MAC. - we may have a copper SFP module with a PHY whic can't be accessed, which means we need to take ethtool/mii data from the MAC. Phylink aims to solve this by providing an intermediary between the MAC and PHY, providing a safe way for PHYs to be hotplugged, and allowing a SFP driver to reconfigure the serdes connection. Phylink also takes over support of fixed link connections, where the speed/duplex/flow control are fixed, but link status may be controlled by a GPIO signal. By avoiding the fixed-phy implementation, phylink can provide a faster response to link events: fixed-phy has to wait for phylib to operate its state machine, which can take several seconds. In comparison, phylink takes milliseconds.

2017-08-06net: phy: provide a hook for link up/link down eventsRussell King1-0/+1
Sometimes, we need to do additional work between the PHY coming up and marking the carrier present - for example, we may need to wait for the PHY to MAC link to finish negotiation. This changes phylib to provide a notification function pointer which avoids the built-in netif_carrier_on() and netif_carrier_off() functions. Standard ->adjust_link functionality is provided by hooking a helper into the new ->phy_link_change method.

phy_lookup_setting() provides useful functionality in ethtool code outside phylib. Move it to phy-core and allow it to be re-used (eg, in phylink) rather than duplicated elsewhere. Note that this supports the larger linkmode space. As we move the phy settings table, we also need to move the guts of phy_supported_speeds() as well.

2017-08-03sock: MSG_ZEROCOPY notification coalescingWillem de Bruijn1-3/+14
In the simple case, each sendmsg() call generates data and eventually a zerocopy ready notification N, where N indicates the Nth successful invocation of sendmsg() with the MSG_ZEROCOPY flag on this socket. TCP and corked sockets can cause send() calls to append new data to an existing sk_buff and, thus, ubuf_info. In that case the notification must hold a range. odify ubuf_info to store a inclusive range [N..N+m] and add skb_zerocopy_realloc() to optionally extend an existing range. Also coalesce notifications in this common case: if a notification [1, 1] is about to be queued while [0, 0] is the queue tail, just modify the head of the queue to read [0, 1]. Coalescing is limited to a few TSO frames worth of data to bound notification latency. Signed-off-by: Willem de Bruijn <willemb@google.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2017-08-03sock: enable MSG_ZEROCOPYWillem de Bruijn1-1/+13
Prepare the datapath for refcounted ubuf_info. Clone ubuf_info with skb_zerocopy_clone() wherever needed due to skb split, merge, resize or clone. Split skb_orphan_frags into two variants. The split, merge, .. paths support reference counted zerocopy buffers, so do not do a deep copy. Add skb_orphan_frags_rx for paths that may loop packets to receive sockets. That is not allowed, as it may cause unbounded latency. Deep copy all zerocopy copy buffers, ref-counted or not, in this path. The exact locations to modify were chosen by exhaustively searching through all code that might modify skb_frag references and/or the the SKBTX_DEV_ZEROCOPY tx_flags bit. The changes err on the safe side, in two ways. (1) legacy ubuf_info paths virtio and tap are not modified. They keep a 1:1 ubuf_info to sk_buff relationship. Calls to skb_orphan_frags still call skb_copy_ubufs and thus copy frags in this case. (2) not all copies deep in the stack are addressed yet. skb_shift, skb_split and skb_try_coalesce can be refined to avoid copying. These are not in the hot path and this patch is hairy enough as is, so that is left for future refinement. Signed-off-by: Willem de Bruijn <willemb@google.com> Signed-off-by: David S.

Notifications are returned with ee_origin SO_EE_ORIGIN_ZEROCOPY. ee_errno is 0 to avoid blocking the send/recv path on receiving notifications.

Refine skb_copy_ubufs to support compound pages. With upcoming TCP zerocopy sendmsg, such fragments may appear. The existing code replaces each page one for one. Splitting each compound page into an independent number of regular pages can result in exceeding limit MAX_SKB_FRAGS if data is not exactly page aligned. Instead, fill all destination pages but the last to PAGE_SIZE. Split the existing alloc + copy loop into separate stages: 1. compute bytelength and minimum number of pages to store this. 2. allocate 3. copy, filling each page except the last to PAGE_SIZE bytes 4. update skb frag array Signed-off-by: Willem de Bruijn <willemb@google.com> Signed-off-by: David S.

Dump all the FIB tables in each net namespace upon registration to the FIB notification chain so that the callee will have a complete view of the tables. The integrity of the dump is ensured by a per-table sequence counter that is incremented (under write lock) whenever a route is added or deleted from the table. All the sequence counters are read (under each table's read lock) and summed, prior and after the dump. In case the counters differ, then the dump is either restarted or the registration fails. While it's possible for a table to be modified after its counter has been read, this isn't really a problem. In case it happened before it was read the second time, then the comparison at the end will fail. If it happened afterwards, then we're guaranteed to be notified about the change, as the notification block is registered prior to the second read.

As with IPv4, allow listeners of the FIB notification chain to receive notifications whenever a route is added, replaced or deleted. This is done by placing calls to the FIB notification chain in the two lowest level functions that end up performing these operations - namely, fib6_add_rt2node() and fib6_del_route(). Unlike IPv4, APPEND notifications aren't sent as the kernel doesn't distinguish between "append" (NLM_F_CREATE|NLM_F_APPEND) and "prepend" (NLM_F_CREATE). If NLM_F_EXCL isn't set, duplicate routes are always added after the existing duplicate routes.

2017-08-03net: core: Make the FIB notification chain genericIdo Schimmel4-22/+54
The FIB notification chain is currently soley used by IPv4 code. However, we're going to introduce IPv6 FIB offload support, which requires these notification as well. As explained in commit c3852ef7f2f8 ("ipv4: fib: Replay events when registering FIB notifier"), upon registration to the chain, the callee receives a full dump of the FIB tables and rules by traversing all the net namespaces. The integrity of the dump is ensured by a per-namespace sequence counter that is incremented whenever a change to the tables or rules occurs. In order to allow more address families to use the chain, each family is expected to register its fib_notifier_ops in its pernet init. These operations allow the common code to read the family's sequence counter as well as dump its tables and rules in the given net namespace. Additionally, a 'family' parameter is added to sent notifications, so that listeners could distinguish between the different families. Implement the common code that allows listeners to register to the chain and for address families to register their fib_notifier_ops. Subsequent patches will implement these operations in IPv6. In the future, ipmr and ip6mr will be extended to provide these notifications as well.

2017-08-01net: dsa: remove PHY device argument from .set_eeeVivien Didelot1-1/+0
The DSA switch operations for EEE are only meant to configure a port's MAC EEE settings. The port's PHY EEE settings are accessed by the DSA layer and must be made available via a proper PHY driver. In order to reduce this confusion, remove the phy_device argument from the .set_eee operation.
