IPv6 already exposes some address family data via netlink in the IFLA_PROTINFO attribute if RTM_GETLINK request is sent with the address family set to AF_INET6. We take over this format and reuse all the code. Signed-off-by: NThomas Graf <tgraf@infradead.org> Cc: YOSHIFUJI Hideaki <yoshfuji@linux-ipv6.org> Signed-off-by: NDavid S.

Implements the AF_INET link address family exposing the per device configuration settings via netlink using the attribute IFLA_INET_CONF. The format of IFLA_INET_CONF differs depending on the direction the attribute is sent. The attribute sent by the kernel consists of a u32 array, basically a 1:1 copy of in_device->cnf.data[]. The attribute expected by the kernel must consist of a sequence of nested u32 attributes, each representing a change request, e.g. [IFLA_INET_CONF] = { [IPV4_DEVCONF_FORWARDING] = 1, [IPV4_DEVCONF_NOXFRM] = 0, } libnl userspace API documentation and example available from: http://www.infradead.org/~tgr/libnl/doc-git/group__link__inet.htmlSigned-off-by: NThomas Graf <tgraf@infradead.org> Signed-off-by: NDavid S.

Each net_device contains address family specific data such as per device settings and statistics. We already expose this data via procfs/sysfs and partially netlink. The netlink method requires the requester to send one RTM_GETLINK request for each address family it wishes to receive data of and then merge this data itself. This patch implements a new API which combines all address family specific link data in a new netlink attribute IFLA_AF_SPEC. IFLA_AF_SPEC contains a sequence of nested attributes, one for each address family which in turn defines the structure of its own attribute. Example: [IFLA_AF_SPEC] = { [AF_INET] = { [IFLA_INET_CONF] = ..., }, [AF_INET6] = { [IFLA_INET6_FLAGS] = ..., [IFLA_INET6_CONF] = ..., } } The API also allows for address families to implement a function which parses the IFLA_AF_SPEC attribute sent by userspace to implement address family specific link options.

The SELinux netfilter hooks just return NF_DROP if they drop a packet. We want to signal that a drop in this hook is a permanant fatal error and is not transient. If we do this the error will be passed back up the stack in some places and applications will get a faster interaction that something went wrong.

The current tcp_connect code completely ignores errors from sending an skb. This makes sense in many situations (like -ENOBUFFS) but I want to be able to immediately fail connections if they are denied by the SELinux netfilter hook. Netfilter does not normally return ECONNREFUSED when it drops a packet so we respect that error code as a final and fatal error that can not be recovered.

The driver can fail initializing the hardware when manageability firmware is performing concurrent MDIO operations because the hardware semaphore scheme to prevent concurrent operations between software and firmware is incorrect for 82574/82583. Instead of using the SWSM register, the driver should be using the EXTCNF_CTRL register. A software mutex is also added to prevent simultaneous software threads from performing similar concurrent accesses.

SerDes Link detection on certain 82571 mezzanine cards can fail when the link is forced, the link partner does not recognize forced link and the link partner sends null code words. Detect the null code words and return to auto-negotiation state which causes the link partner to begin responding with valid code words. Within a reasonable interval the link will finally settle as forced by both partners. Signed-off-by: NBruce Allan <bruce.w.allan@intel.com> Signed-off-by: NJeff Kirsher <jeffrey.t.kirsher@intel.com>

When invalidating the DDP context is invalidated, the HW may not be done with the user buffer right away. In which case, we poll the FCBUFF register to check if the buffer valid bit is cleared or not, if not, we wait for max 100us that is guaranteed by the HW.

The hw automatically invalidates the context if DDP is successful or there is error detected. In case there is no error status available from the hw, initializing the per context error status to be 1 allows the DDP context to be still invalidated via the upper layer call to ddp_put().

The Tx hang logic has been known to detect false hangs when the device is receiving pause frames or has delayed processing for some other reason. This patch makes the logic more robust and resolves these known issues. The old logic checked to see if the device was paused by querying the HW then the hang logic was aborted if the device was currently paused. This check was racy because the device could have been in the pause state any time up to this check. The other operation of the hang logic is to verify the Tx ring is still advancing the old logic checked the EOP timestamp. This is not sufficient to determine the ring is not advancing but only infers that it may be moving slowly. Here we add logic to track the number of completed Tx descriptors and use the adapter stats to check if any pause frames have been received since the previous Tx hang check. This way we avoid racing with the HW register and do not detect false hangs if the ring is advancing slowly. This patch is primarily the work of Jesse Brandeburg. I clean it up some and fixed the PFC checking.
