2012-08-31tcp: TCP Fast Open Server - header & support functionsJerry Chu
This patch adds all the necessary data structure and support functions to implement TFO server side. It also documents a number of flags for the sysctl_tcp_fastopen knob, and adds a few Linux extension MIBs. In addition, it includes the following: 1. a new TCP_FASTOPEN socket option an application must call to supply a max backlog allowed in order to enable TFO on its listener. 2. A number of key data structures: "fastopen_rsk" in tcp_sock - for a big socket to access its request_sock for retransmission and ack processing purpose. It is non-NULL iff 3WHS not completed. "fastopenq" in request_sock_queue - points to a per Fast Open listener data structure "fastopen_queue" to keep track of qlen (# of outstanding Fast Open requests) and max_qlen, among other things. "listener" in tcp_request_sock - to point to the original listener for book-keeping purpose, i.e., to maintain qlen against max_qlen as part of defense against IP spoofing attack. 3. various data structure and functions, many in tcp_fastopen.c, to support server side Fast Open cookie operations, including /proc/sys/net/ipv4/tcp_fastopen_key to allow manual rekeying.

2012-08-31bonding: add some slack to arp monitoring time limitsJiri Bohac
Currently, all the time limits in the bonding ARP monitor are in multiples of arp_interval -- the time interval at which the ARP monitor is periodically scheduled. With a fast network round-trip and a little scheduling latency of the ARP monitor work, a limit of n*delta_in_ticks may effectively mean (n-1)*delta_in_ticks. This is fatal in case of n==1 (the link will stay down forever) and makes the behaviour non-deterministic in all the other cases. Add a delta_in_ticks/2 time slack to all the time limits.

2012-08-31net: fix documentation of skb_needs_linearize().Rami Rosen
skb_needs_linearize() does not check highmem DMA as it does not call illegal_highdma() anymore, so there is no need to mention highmem DMA here. (Indeed, ~NETIF_F_SG flag, which is checked in skb_needs_linearize(), can be set when illegal_highdma() returns true, and we are assured that illegal_highdma() is invoked prior to skb_needs_linearize() as skb_needs_linearize() is a static method called only once. But ~NETIF_F_SG can be set not only there in this same invocation path. It can also be set when can_checksum_protocol() returns false). see commit 02932ce9e2c136e6fab2571c8e0dd69ae8ec9853, Convert skb_need_linearize() to use precomputed features.

2012-08-31ipv4: Minor logic clean-up in ipv4_mtuAlexander Duyck
In ipv4_mtu there is some logic where we are testing for a non-zero value and a timer expiration, then setting the value to zero, and then testing if the value is zero we set it to a value based on the dst. Instead of bothering with the extra steps it is easier to just cleanup the logic so that we set it to the dst based value if it is zero or if the timer has expired.

2012-08-31net:stmmac: Remove bus_id from mdio platform data.Srinivas Kandagatla
This patch removes bus_id from mdio platform data, The reason to remove bus_id is, stmmac mdio bus_id is always same as stmmac bus-id, so there is no point in passing this in different variable. Also stmmac ethernet driver connects to phy with bus_id passed its platform data. So, having single bus-id is much simpler.

2012-08-31net:stmmac: fix broken stmmac_pltfr_remove.Srinivas Kandagatla
This patch fixes stmmac_pltfr_remove function, which is broken because, it is accessing plat variable via freed memory priv pointer which gets freed by free_netdev called from stmmac_dvr_remove. In short this patch caches the plat pointer in local variable before calling stmmac_dvr_remove to prevent code accessing freed memory. Without this patch any attempt to remove the stmmac device will fail as below: Unregistering eth 0 ...

2012-08-31net:stmmac: Add check if mdiobus is registered in stmmac_mdio_unregisterSrinivas Kandagatla
This patch adds a basic check in stmmac_mdio_unregister to see if mdio bus registeration for this driver was actually sucessfull or not. Use case here is, if BSP considers using mdio-gpio bus along with stmmac driver by passing mdio_bus_data as NULL in platform data. Call to stmmac_mdio_register with mdio_bus_data as NULL returns 0, which is a considered sucessfull call form stmmac. Then again when we unload the driver we just call stmmac_mdio_unregister, this is were the actual problem is stmmac-mdio code dont really know at this instance of calling that stmmac_mdio_register was actually successful. So Adding a check in stmmac_mdio_unregister is always safe. Without this patch stmmac driver calls stmmac_mdio_register from stmmac_release which Segfaults as mii bus was never registered at the first point. Originally the this bug was found when unloading an stmmac driver instance which uses mdio-gpio for smi access. Signed-off-by: Srinivas Kandagatla <srinivas.kandagatla@st.com> Signed-off-by: David S.

2012-08-31tcp: Increase timeout for SYN segmentsAlex Bergmann
Commit 9ad7c049 ("tcp: RFC2988bis + taking RTT sample from 3WHS for the passive open side") changed the initRTO from 3secs to 1sec in accordance to RFC6298 (former RFC2988bis). This reduced the time till the last SYN retransmission packet gets sent from 93secs to 31secs. RFC1122 is stating that the retransmission should be done for at least 3 minutes, but this seems to be quite high. "However, the values of R1 and R2 may be different for SYN and data segments. In particular, R2 for a SYN segment MUST be set large enough to provide retransmission of the segment for at least 3 minutes. The application can close the connection (i.e., give up on the open attempt) sooner, of course." This patch increases the value of TCP_SYN_RETRIES to the value of 6, providing a retransmission window of 63secs. The comments for SYN and SYNACK retries have also been updated to describe the current settings. The same goes for the documentation file "Documentation/networking/ip-sysctl.txt".

2012-08-31netfilter: nf_conntrack: fix racy timer handling with reliable eventsPablo Neira Ayuso
Existing code assumes that del_timer returns true for alive conntrack entries. However, this is not true if reliable events are enabled. In that case, del_timer may return true for entries that were just inserted in the dying list. Note that packets / ctnetlink may hold references to conntrack entries that were just inserted to such list. This patch fixes the issue by adding an independent timer for event delivery. This increases the size of the ecache extension. Still we can revisit this later and use variable size extensions to allocate this area on demand.

The main motivation behind this is that the vf.c file is supposed to contain all of the messages used when communicating with the PF. In addition it creates a separate function for setting the Rx buffer size so that we have on centralized area to review what buffer sizes will be requested by the VF.

2012-08-30net/fsl_pq_mdio: streamline probing of MDIO nodesTimur Tabi
Make the device tree probe function more data-driven, so that it no longer searches the 'compatible' property more than once. The of_device_id[] array allows for per-entry private data, so we use that to store details about each type of node that the driver supports. This removes the need to check the 'compatible' property inside the probe function. The driver supports four types on MDIO devices: 1) Gianfar MDIO nodes that only map the MII registers 2) Gianfar MDIO nodes that map the full MDIO register set 3) eTSEC2 MDIO nodes (which map the full MDIO register set) 4) QE MDIO nodes (which map only the MII registers) Gianfar, eTSEC2, and QE have different mappings for the TBIPA register, which is needed to initialize the TBI PHY. In addition, the QE needs a special hack because of the way the device tree is ordered. All of this information is encapsulated in the fsl_pq_mdio_data structure, so when an MDIO node is probed, per-device data and functions are used to determine how to initialize the device.

2012-08-30be2net: create RSS rings even in multi-channel configsSathya Perla
Changes from commit df505e were incorrectly over-written by commit 10ef9ab. Fixing the same. Change log of the original fix: Currently RSS rings are not created in a multi-channel config. RSS rings can be created on one (out of four) interfaces per port in a multi-channel config. Doing this insulates the driver from a FW bug wherin multi-channel config is wrongly reported even when not enabled. This also helps performance in a multi-channel config, as one interface per port gets RSS rings. Signed-off-by: Sathya Perla <sathya.perla@emulex.com> Signed-off-by: David S.

The IEEE 802.15.4 standard represents a networking protocol. I don't exactly know why drivers for this protocol are stored into the root 'driver' folder, but better will be to store them with other networking stuff. Currently there are only 3 drivers available for IEEE 802.15.4 stack, so lets do it now with the smallest overhead.

2012-08-30forcedeth: prevent TX timeouts after rebootdavid decotigny
This complements patch "net-forcedeth: fix TX timeout caused by TX pause on down link" which ensures that a lock-up sequence is not sent to the NIC. Present patch ensures that if a NIC is already locked-up, the driver will recover from it when initializing the device. It does the equivalent of the following recovery sequence: - write NVREG_TX_PAUSEFRAME_ENABLE_V1 to eth1's register NvRegTxPauseFrame - write NVREG_XMITCTL_START to eth1's register NvRegTransmitterControl - write 0 to eth1's register NvRegTransmitterControl (this is at the heart of the "unbricking" sequence mentioned in patch "net-forcedeth: fix TX timeout caused by TX pause on down link") Tested: - hardware is MCP55 device id 10de:0373 (rev a3), dual-port - reboot a kernel without any of patches mentioned - freeze the NIC (details on description for commit "net-forcedeth: fix TX timeout caused by TX pause on down link") - wait 5mn until ping hangs & TX timeout in dmesg - reboot on kernel with present patch - host is immediatly operational, no TX timeout Signed-off-by: David Decotigny <decot@googlers.com> Signed-off-by: David S.

2012-08-30forcedeth: fix TX timeout caused by TX pause on down linkdavid decotigny
On some dual-port forcedeth devices such as MCP55 10de:0373 (rev a3), when autoneg & TX pause are enabled while port is connected but interface is down, the NIC will eventually freeze (TX timeouts, network unreachable). This patch ensures that TX pause is not configured in hardware when interface is down. The TX pause request will be honored when interface is later configured. Tested: - hardware is MCP55 device id 10de:0373 (rev a3), dual-port - eth0 connected and UP, eth1 connected but DOWN - without this patch, following sequence would brick NIC: ifconfig eth0 down ifconfig eth1 up ifconfig eth1 down ethtool -A eth1 autoneg off rx on tx off ifconfig eth1 up ifconfig eth1 down ethtool -A eth1 autoneg on rx on tx on ifconfig eth1 up ifconfig eth1 down ifup eth0 sleep 120 # or longer ethtool eth1 Just in case, sequence to un-brick: ifconfig eth0 down ethtool -A eth1 autoneg off rx on tx off ifconfig eth1 up ifconfig eth1 down ifup eth0 - with this patch: no TX timeout after "bricking" sequence above Details: - The following register accesses have been identified as the ones causing the NIC to freeze in "bricking" sequence above: - write NVREG_TX_PAUSEFRAME_ENABLE_V1 to eth1's register NvRegTxPauseFrame - write NVREG_MISC1_PAUSE_TX | NVREG_MISC1_FORCE to eth1's register NvRegMisc1 - write 0 to eth1's register NvRegTransmitterControl This is what this patch avoids.
