Instead of iterating in_dev->mc_list from bonding driver, its better to call a helper function provided by igmp.c Details of implementation (locking) are private to igmp code. ip_mc_rejoin_group(struct ip_mc_list *im) becomes ip_mc_rejoin_groups(struct in_device *in_dev); Signed-off-by:

snprintf() returns number of bytes that were copied if there is no overflow. This code uses return value as number of copied bytes. Theoretically format string '%lu.%09lu %pI4:%u %pI4:%u %d %#x %#x %u %u %u %u\n' may be expanded up to 163 bytes. In reality tv.tv_sec is just few bytes instead of 20, 2 ports are just 5 bytes each instead of 10, length is 5 bytes instead of 10. The rest is an unstrusted input. Theoretically if tv_sec is big then copy_to_user() would overflow tbuf. tbuf was increased to fit in 163 bytes. snprintf() is used to follow return value semantic. Signed-off-by:

netif_set_real_num_rx_queues() can decrement and increment the number of rx queues. For example ixgbe does this as features and offloads are toggled. Presumably this could also happen across down/up on most devices if the available resources changed (cpu offlined). The kobject needs to be zero'd in this case so that the state is not preserved across kobject_put()/kobject_init_and_add(). This resolves the following error report. ixgbe 0000:03:00.0: eth2: NIC Link is Up 10 Gbps, Flow Control: RX/TX kobject (ffff880324b83210): tried to init an initialized object, something is seriously wrong.

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:

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: -

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. Signed-off-by:

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. Based-on-patch-by:

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. Signed-off-by:

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:
