2016-02-25net: ethtool: add new ETHTOOL_xLINKSETTINGS APIDavid Decotigny3-80/+786
This patch defines a new ETHTOOL_GLINKSETTINGS/SLINKSETTINGS API, handled by the new get_link_ksettings/set_link_ksettings callbacks. This API provides support for most legacy ethtool_cmd fields, adds support for larger link mode masks (up to 4064 bits, variable length), and removes ethtool_cmd deprecated fields (transceiver/maxrxpkt/maxtxpkt). This API is deprecating the legacy ETHTOOL_GSET/SSET API and provides the following backward compatibility properties: - legacy ethtool with legacy drivers: no change, still using the get_settings/set_settings callbacks. - legacy ethtool with new get/set_link_ksettings drivers: the new driver callbacks are used, data internally converted to legacy ethtool_cmd. ETHTOOL_GSET will return only the 1st 32b of each link mode mask. ETHTOOL_SSET will fail if user tries to set the ethtool_cmd deprecated fields to non-0 (transceiver/maxrxpkt/maxtxpkt). A kernel warning is logged if driver sets higher bits. - future ethtool with legacy drivers: no change, still using the get_settings/set_settings callbacks, internally converted to new data structure. Deprecated fields (transceiver/maxrxpkt/maxtxpkt) will be ignored and seen as 0 from user space. Note that that "future" ethtool tool will not allow changes to these deprecated fields. - future ethtool with new drivers: direct call to the new callbacks. By "future" ethtool, what is meant is: - query: first try ETHTOOL_GLINKSETTINGS, and revert to ETHTOOL_GSET if fails - set: query first and remember which of ETHTOOL_GLINKSETTINGS or ETHTOOL_GSET was successful + if ETHTOOL_GLINKSETTINGS was successful, then change config with ETHTOOL_SLINKSETTINGS. A failure there is final (do not try ETHTOOL_SSET). + otherwise ETHTOOL_GSET was successful, change config with ETHTOOL_SSET. A failure there is final (do not try ETHTOOL_SLINKSETTINGS). The interaction user/kernel via the new API requires a small ETHTOOL_GLINKSETTINGS handshake first to agree on the length of the link mode bitmaps. If kernel doesn't agree with user, it returns the bitmap length it is expecting from user as a negative length (and cmd field is 0). When kernel and user agree, kernel returns valid info in all fields (ie. link mode length > 0 and cmd is ETHTOOL_GLINKSETTINGS). Data structure crossing user/kernel boundary is 32/64-bit agnostic. Converted internally to a legal kernel bitmap. The internal __ethtool_get_settings kernel helper will gradually be replaced by __ethtool_get_link_ksettings by the time the first "link_settings" drivers start to appear. So this patch doesn't change it, it will be removed before it needs to be changed. Signed-off-by: David Decotigny <decot@googlers.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2016-02-25net: Facility to report route quality of connected socketsTom Herbert14-0/+30
This patch add the SO_CNX_ADVICE socket option (setsockopt only). The purpose is to allow an application to give feedback to the kernel about the quality of the network path for a connected socket. The value argument indicates the type of quality report. For this initial patch the only supported advice is a value of 1 which indicates "bad path, please reroute"-- the action taken by the kernel is to call dst_negative_advice which will attempt to choose a different ECMP route, reset the TX hash for flow label and UDP source port in encapsulation, etc. This facility should be useful for connected UDP sockets where only the application can provide any feedback about path quality. It could also be useful for TCP applications that have additional knowledge about the path outside of the normal TCP control loop.

2016-02-25net: ipv6: Make address flushing on ifdown optionalDavid Ahern4-15/+132
Currently, all ipv6 addresses are flushed when the interface is configured down, including global, static addresses: $ ip -6 addr show dev eth1 3: eth1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 state UP qlen 1000 inet6 2100:1::2/120 scope global valid_lft forever preferred_lft forever inet6 fe80::e0:f9ff:fe79:34bd/64 scope link valid_lft forever preferred_lft forever $ ip link set dev eth1 down $ ip -6 addr show dev eth1 << nothing; all addresses have been flushed>> Add a new sysctl to make this behavior optional. The new setting defaults to flush all addresses to maintain backwards compatibility. When the set global addresses with no expire times are not flushed on an admin down. The sysctl is per-interface or system-wide for all interfaces $ sysctl -w net.ipv6.conf.eth1.keep_addr_on_down=1 or $ sysctl -w net.ipv6.conf.all.keep_addr_on_down=1 Will keep addresses on eth1 on an admin down. $ ip -6 addr show dev eth1 3: eth1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 state UP qlen 1000 inet6 2100:1::2/120 scope global valid_lft forever preferred_lft forever inet6 fe80::e0:f9ff:fe79:34bd/64 scope link valid_lft forever preferred_lft forever $ ip link set dev eth1 down $ ip -6 addr show dev eth1 3: eth1: <BROADCAST,MULTICAST> mtu 1500 state DOWN qlen 1000 inet6 2100:1::2/120 scope global tentative valid_lft forever preferred_lft forever inet6 fe80::e0:f9ff:fe79:34bd/64 scope link tentative valid_lft forever preferred_lft forever Signed-off-by: David Ahern <dsa@cumulusnetworks.com> Signed-off-by: David S.

2016-02-25tipc: fix crash during node removalJon Paul Maloy1-13/+11
When the TIPC module is unloaded, we have identified a race condition that allows a node reference counter to go to zero and the node instance being freed before the node timer is finished with accessing it. This leads to occasional crashes, especially in multi-namespace environments. The scenario goes as follows: CPU0:(node_stop) CPU1:(node_timeout) // ref == 2 1: if(!mod_timer()) 2: if (del_timer()) 3: tipc_node_put() // ref -> 1 4: tipc_node_put() // ref -> 0 5: kfree_rcu(node); 6: tipc_node_get(node) 7: // BOOM! We now clean up this functionality as follows: 1) We remove the node pointer from the node lookup table before we attempt deactivating the timer. This way, we reduce the risk that tipc_node_find() may obtain a valid pointer to an instance marked for deletion; a harmless but undesirable situation. 2) We use del_timer_sync() instead of del_timer() to safely deactivate the node timer without any risk that it might be reactivated by the timeout handler. There is no risk of deadlock here, since the two functions never touch the same spinlocks. 3: We remove a pointless tipc_node_get() + tipc_node_put() from the timeout handler.

2016-02-25tipc: eliminate risk of finding to-be-deleted node instanceJon Paul Maloy1-9/+9
Although we have never seen it happen, we have identified the following problematic scenario when nodes are stopped and deleted: CPU0: CPU1: tipc_node_xxx() //ref == 1 tipc_node_put() //ref -> 0 tipc_node_find() // node still in table tipc_node_delete() list_del_rcu(n. list) tipc_node_get() //ref -> 1, bad kfree_rcu() tipc_node_put() //ref to 0 again. kfree_rcu() // BOOM! We fix this by introducing use of the conditional kref_get_if_not_zero() instead of kref_get() in the function tipc_node_find(). This eliminates any risk of post-mortem access.

Move the mapping of the head BD before the mapping of fragments.

Note that, for this h/w, the R (status) bit for the head BD of a S/G frame needs to be written last for a reliable transmission. For the fragmented skb case, a local variable is used to temporarily store the status info of the first BD, replacing a BD status read. A merge of 2 "if(do_tstamp)" blocks was also possible.

In QnQ configurations like Flex-10 where the VLANs are inserted by the ASIC, on rare occasions the HW is encountering a scenario where the final frame length ends to be greater than what the ASIC can support. This is because when the TXULP pulls the TX WRB to check the length of the frame to be transmitted it also adds the size of VLANs to be inserted by the HW to the length of the frame indicated in the WRB, which in some cases fails the range check. This causes a UE. Avoid this by trimming the skb length to accommodate the VLAN insertion. Signed-off-by: Ajit Khaparde <ajit.khaparde@broadcom.com> Signed-off-by: David S.
