The rx_urb_size is set to the same value for every device supported by this driver. No need to keep a per-device data structure to do that. Replacing with a macro constant. This was the last device specific info, and removing it allows us to delete the sierra_net_info_data struct. Signed-off-by:

Since lowpan_process_data() modifies the skb (by calling skb_pull()), we need our own copy so that it doesn't affect the data received by other protcols (in this case, af_ieee802154). Signed-off-by:

Jerry Chu says: ==================== This patch series provides the server (passive open) side code for TCP Fast Open. Together with the earlier client side patches it completes the TCP Fast Open implementation. The server side Fast Open code accepts data carried in the SYN packet with a valid Fast Open cookie, and passes it to the application right away, allowing application to send back response data, all before TCP's 3-way handshake finishes. A simple cookie scheme together with capping the number of outstanding TFO requests (still in TCP_SYN_RECV state) to a limit per listener forms the main line of defense against spoofed SYN attacks. For more details about TCP Fast Open see our IETF internet draft at http://www.ietf.org/id/draft-ietf-tcpm-fastopen-01.txt and a research paper at http://conferences.sigcomm.org/co-next/2011/papers/1569470463.pdf A prototype implementation was first developed by Sivasankar Radhakrishnan (sivasankar@cs.ucsd.edu). A patch based on an older version of Linux kernel has been undergoing internal tests at Google for the past few months.

This patch adds the main processing path to complete the TFO server patches. A TFO request (i.e., SYN+data packet with a TFO cookie option) first gets processed in tcp_v4_conn_request(). If it passes the various TFO checks by tcp_fastopen_check(), a child socket will be created right away to be accepted by applications, rather than waiting for the 3WHS to finish. In additon to the use of TFO cookie, a simple max_qlen based scheme is put in place to fend off spoofed TFO attack. When a valid ACK comes back to tcp_rcv_state_process(), it will cause the state of the child socket to switch from either TCP_SYN_RECV to TCP_ESTABLISHED, or TCP_FIN_WAIT1 to TCP_FIN_WAIT2. At this time retransmission will resume for any unack'ed (data, FIN,...) segments. Signed-off-by:

This patch builds on top of the previous patch to add the support for TFO listeners. This includes - 1. allocating, properly initializing, and managing the per listener fastopen_queue structure when TFO is enabled 2. changes to the inet_csk_accept code to support TFO. E.g., the request_sock can no longer be freed upon accept(), not until 3WHS finishes 3. allowing a TCP_SYN_RECV socket to properly poll() and sendmsg() if it's a TFO socket 4. properly closing a TFO listener, and a TFO socket before 3WHS finishes 5. supporting TCP_FASTOPEN socket option 6. modifying tcp_check_req() to use to check a TFO socket as well as request_sock 7. supporting TCP's TFO cookie option 8. adding a new SYN-ACK retransmit handler to use the timer directly off the TFO socket rather than the listener socket. Note that TFO server side will not retransmit anything other than SYN-ACK until the 3WHS is completed. The patch also contains an important function "reqsk_fastopen_remove()" to manage the somewhat complex relation between a listener, its request_sock, and the corresponding child socket. See the comment above the function for the detail. Signed-off-by:

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.

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.

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 02932ce9, Convert skb_need_linearize() to use precomputed features. Signed-off-by:

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. Signed-off-by:

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. Signed-off-by:

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 ...

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:

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". Signed-off-by:

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. Tested-by:

This change moves the code for notifying the PF of the VF maximum packet size into the vf.c file. 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. Signed-off-by:
