This patch makes use of the new state_lock to synchronise between updates to the ifa state. This fixes the issue where a remotely triggered address deletion (through DAD failure) coincides with a local administrative address deletion, causing certain actions to be performed twice incorrectly.

Herbert Xu authored
This patch replaces the boolean dead flag on inet6_ifaddr with a state enum. This allows us to roll back changes when deleting an address according to whether DAD has completed or not. This patch only adds the state field and does not change the logic. Signed-off-by:

The PF driver needs to remain alert while its ports are down to service requests or errors from virtual functions or FW so keep interrupts and queues available when the ports are brought down. The change makes open_device_map unnecessary so remove it. Signed-off-by:

Everytime the iSCSI ring finishes setup or shutdown, we need to return the SPQ (slow path queue) credit to the bnx2x driver. Without this step, the SPQ will eventually be full causing iSCSI to fail. This can happen after 3 or 4 MTU changes for example. Add code to wait for these slow path commands to complete in the RX ring and return the SPQ credit to bnx2x. Signed-off-by:

It is easier to expand the flags for other purposes because it does not require a spin_lock. The next bug fix patch needs a flag in cnic_local_flags. Signed-off-by:

The SJA1000 command register is concurrently written in the rx-path to free the receive buffer _and_ in the tx-path to start the transmission. The SJA1000 data sheet, 6.4.4 COMMAND REGISTER (CMR) states: "Between two commands at least one internal clock cycle is needed in order to proceed. The internal clock is half of the external oscillator frequency." On SMP systems the current implementation leads to a write stall in the tx-path, which can be solved by adding some general locking and some time to settle the write_reg() operation for the command register. Thanks to Klaus Hitschler for the original fix and detailed problem description. This patch applies on net-2.6 and (with some offsets) on net-next-2.6 . Signed-off-by:

The SH SOHARD ARCNET cards are implemented using generic PLX Technology PCI<->IOBus bridges. Subvendor and subdevice IDs were not specified, causing the driver to attach to any such bridge and likely crash the system by attempting to initialize an unrelated device. Fix by specifying subvendor and subdevice according to the values found in the PCI-ID Repository at http://pci-ids.ucw.cz/ . Cc: stable@kernel.org Signed-off-by:

This patch removes from net/ (but not any netfilter files) all the unnecessary return; statements that precede the last closing brace of void functions. It does not remove the returns that are immediately preceded by a label as gcc doesn't like that. Done via: $ grep -rP --include=*.[ch] -l "return;\n}" net/ | \ xargs perl -i -e 'local $/ ; while (<>) { s/\n[ \t\n]+return;\n}/\n}/g; print; }' Signed-off-by:Joe Perches <joe@perches.com> Signed-off-by:

If the user has a bad classification configuration, and gets a packet that goes through too many steps. Chances are more packets will arrive, and the message spew will overrun syslog because it is not rate limited. And because it is not tagged with appropriate priority it can't not be screened. Added the qdisc to the message to try and give some more context when the message does arrive. Signed-off-by:

The previous patch encourage me to go look at all the messages in the network scheduler and fix them. Many messages were missing any severity level. Some serious ones that should never happen were turned into WARN(), and the random noise messages that were handled changed to pr_debug(). Signed-off-by:

Add enic ndo_{set|get}_vf_port ops to support setting/getting port-profile for enic dynamic devices. Enic dynamic devices are just like normal enic eth devices except dynamic enics require an extra configuration step to assign a port-profile identifier to the interface before the interface is useable. Once a port-profile is assigned, link comes up on the interface and is ready for I/O. The port-profile is used to configure the network port assigned to the interface. The network port configuration includes VLAN membership, QoS policies, and port security settings typical of a data center network. A dynamic enic initially has a zero-mac address. Before a port-profile is assigned, a valid non-zero unicast mac address should be assign to the dynamic enic interface. Signed-off-by:Scott Feldman <scofeldm@cisco.com> Signed-off-by:

Add new netdev ops ndo_{set|get}_vf_port to allow setting of port-profile on a netdev interface. Extends netlink socket RTM_SETLINK/ RTM_GETLINK with two new sub msgs called IFLA_VF_PORTS and IFLA_PORT_SELF (added to end of IFLA_cmd list). These are both nested atrtibutes using this layout: [IFLA_NUM_VF] [IFLA_VF_PORTS] [IFLA_VF_PORT] [IFLA_PORT_*], ... [IFLA_VF_PORT] [IFLA_PORT_*], ... ... [IFLA_PORT_SELF] [IFLA_PORT_*], ... These attributes are design to be set and get symmetrically. VF_PORTS is a list of VF_PORTs, one for each VF, when dealing with an SR-IOV device. PORT_SELF is for the PF of the SR-IOV device, in case it wants to also have a port-profile, or for the case where the VF==PF, like in enic patch 2/2 of this patch set. A port-profile is used to configure/enable the external switch virtual port backing the netdev interface, not to configure the host-facing side of the netdev. A port-profile is an identifier known to the switch. How port- profiles are installed on the switch or how available port-profiles are made know to the host is outside the scope of this patch. There are two types of port-profiles specs in the netlink msg. The first spec is for 802.1Qbg (pre-)standard, VDP protocol. The second spec is for devices that run a similar protocol as VDP but in firmware, thus hiding the protocol details. In either case, the specs have much in common and makes sense to define the netlink msg as the union of the two specs. For example, both specs have a notition of associating/deassociating a port-profile. And both specs require some information from the hypervisor manager, such as client port instance ID. The general flow is the port-profile is applied to a host netdev interface using RTM_SETLINK, the receiver of the RTM_SETLINK msg communicates with the switch, and the switch virtual port backing the host netdev interface is configured/enabled based on the settings defined by the port-profile. What those settings comprise, and how those settings are managed is again outside the scope of this patch, since this patch only deals with the first step in the flow. Signed-off-by: -

The member "clock" of struct "sja1000_platform_data" is documented as "CAN bus oscillator frequency in Hz" but it's actually used as the CAN clock frequency, which is half of it. To avoid further confusion, this patch fixes it by renaming the member to "osc_freq". That way, also non mainline users will notice the change. The platform code for the relevant boards is updated accordingly. Furthermore, pre-defined values are now used for the members "ocr" and "cdr". Signed-off-by:

Commit 33ad798c (tcp: options clean up) introduced a problem if MD5+SACK+timestamps were used in initial SYN message. Some stacks (old linux for example) try to negotiate MD5+SACK+TSTAMP sessions, but since 40 bytes of tcp options space are not enough to store all the bits needed, we chose to disable timestamps in this case. We send a SYN-ACK _without_ timestamp option, but socket has timestamps enabled and all further outgoing messages contain a TS block, all with the initial timestamp of the remote peer. Fix is to really disable timestamps option for the whole session. Reported-by:

dm9000_set_rx_csum and dm9000_hash_table are called from atomic context (in dm9000_init_dm9000), and from non-atomic context (via ethtool_ops and net_device_ops respectively). This causes a spinlock recursion BUG. Fix this by renaming these functions to *_unlocked for the atomic context, and make the original functions locking wrappers for use in the non-atomic context.

When attaching filters to a class pointing to a class higher up in the hierarchy, classification may enter an endless loop. Currently this is prevented for filters that are already resolved, but not for filters resolved at runtime. Only allow filters to point downwards in the hierarchy, similar to what CBQ does.
