MAC devices use the RWKPKTEN and MGKPKTEN bits of the PMT Control/Status register to generate power management events. So this patch is to properly set the RWKPKTEN [BIT(2)] inside the PMT register (needed in case of global unicast).

Commit 6e7333d3 "net: add rx_nohandler stat counter" added the new entry rx_nohandler into struct rtnl_link_stats64. Unfortunately the bna driver foolishly depends on the structure. It uses part of it for ethtool statistics and it's not bad but the driver assumes its size is constant as it defines string for each existing entry. The problem occurs when the structure is extended because you need to modify bna driver as well. If not any attempt to retrieve ethtool statistics results in crash in bnad_get_strings(). The patch changes BNAD_ETHTOOL_STATS_NUM so it counts real number of strings in the array and also removes rtnl_link_stats64 entries that are not used in output and are always zero.

A malicious TCP receiver, sending SACK, can force the sender to split skbs in write queue and increase its memory usage. Then, when socket is closed and its write queue purged, we might overflow sk_forward_alloc (It becomes negative) sk_mem_reclaim() does nothing in this case, and more than 2GB are leaked from TCP perspective (tcp_memory_allocated is not changed) Then warnings trigger from inet_sock_destruct() and sk_stream_kill_queues() seeing a not zero sk_forward_alloc All TCP stack can be stuck because TCP is under memory pressure. A simple fix is to preemptively reclaim from sk_mem_uncharge(). This makes sure a socket wont have more than 2 MB forward allocated, after burst and idle period.

In case of error during netback_probe() (e.g. an entry missing on the xenstore) netback_remove() is called on the new device, which will set the device backend state to XenbusStateClosed by calling set_backend_state(). However, the backend state wasn't initialized by netback_probe() at this point, which will cause and invalid transaction and set_backend_state() to BUG(). Initialize the backend state at the beginning of netback_probe() to XenbusStateInitialising, and create two new valid state transitions on set_backend_state(), from XenbusStateInitialising to XenbusStateClosed, and from XenbusStateInitialising to XenbusStateInitWait.

commit 5f78e29c ("qeth: optimize IP handling in rx_mode callback") restructured the internal address handling. This work broke setting a virtual IP address. The command echo 10.1.1.1 > /sys/bus/ccwgroup/devices/<device>/vipa/add4 fails with file exist error even if the IP address has not been set before. It turned out that the search result for the IP address search is handled incorrectly in the VIPA case. This patch fixes the setting of an virtual IP address.

According to recent performance measurements, turning on net_device feature NETIF_F_SG only behaves well, but turning on feature NETIF_F_GSO shows bad results. Since the kernel activates NETIF_F_GSO automatically as soon as the driver configures feature NETIF_F_SG, qeth should not activate feature NETIF_F_SG per default, until the qeth problems with NETIF_F_GSO are solved.

To reduce the need of skb_linearize() calls, gso_max_segs of qeth net_devices had been limited according to the maximum number of qdio SBAL elements. But a gso segment cannot be larger than the mtu-size, while an SBAL element can contain up to 4096 bytes. The gso_max_segs limitation limits the maximum packet size given to the qeth driver. Performance measurements with tso-enabled qeth network interfaces and mtu-size 1500 showed, that the disadvantage of smaller packets is much more severe than the advantage of fewer skb_linearize() calls. This patch gets rid of the gso_max_segs limitations in the qeth driver.

After device recovery, only a basic set of network device features is enabled on the device. If features like checksum offloading or TSO were enabled by the user before the recovery, this results in a mismatch between the network device features, that the kernel assumes to be enabled on the device, and the features actually enabled on the device. This patch tries to restore previously set features, that require changes on the device, after the recovery of a device.

The function ip_rcv_finish() calls l3mdev_ip_rcv(). On any VRF except the global VRF, this replaces skb->dev with the VRF master interface. When calling ip_route_input_noref() from here, the checks for forwarding look at this master device instead of the initial ingress interface. This will allow packets to be routed which normally would be dropped. For example, an interface that is not assigned an IP address should drop packets, but because the checking is against the master device, the packet will be forwarded. The fix here is to still call l3mdev_ip_rcv(), but remember the initial net_device. This is passed to the other functions within ip_rcv_finish, so they still see the original interface.

Since commit 4f008781 ("sctp: apply rhashtable api to send/recv path"), sctp uses transport rhashtable with .obj_cmpfn sctp_hash_cmp, in which it compares the members of the transport with the rhashtable args to check if it's the right transport. But sctp uses the transport without holding it in sctp_hash_cmp, it can cause a use-after-free panic. As after it gets transport from hashtable, another CPU may close the sk and free the asoc. In sctp_association_free, it frees all the transports, meanwhile, the assoc's refcnt may be reduced to 0, assoc can be destroyed by sctp_association_destroy. So after that, transport->assoc is actually an unavailable memory address in sctp_hash_cmp. Although sctp_hash_cmp is under rcu_read_lock, it still can not avoid this, as assoc is not freed by RCU. This patch is to hold the transport before checking it's members with sctp_transport_hold, in which it checks the refcnt first, holds it if it's not 0.

When system enters into kdump kernel because of kernel panic, it won't shutdown devices. On-flight DMA will continue transferring data until device driver initializes. All devices are supposed to reset during driver initialization. And this property is used to fix the kdump failure in system with intel iommu. Other systems with hardware iommu should be similar. Please check commit 091d42e4 ("iommu/vt-d: Copy translation tables from old kernel") and those commits around. But bnx2 driver doesn't reset device during driver initialization. The device resetting is deferred to net device up stage. This will cause hardware iommu handling failure on bnx2 device. And its resetting relies on firmware. So in this patch move the firmware requesting code to earlier bnx2_init_one(), then next call bnx2_reset_chip to reset device. Signed-off-by: NBaoquan He <bhe@redhat.com> Signed-off-by: NDavid S.

A fixed mpath was not quite being treated as such: 1) if a PERR frame was received, a fixed mpath was deactivated. 2) queued path discovery for fixed mpath was potentially being considered, changing mpath state. 3) other mpath flags were potentially being inherited when fixing the mpath. Just assign PATH_FIXED and SN_VALID. This solves several issues when fixing a mesh path in one direction. The reverse direction mpath should probably also be fixed, or root announcements at least be enabled.

When using intermediate queues, sequence number allocation is deferred until dequeue. This doesn't work for PS response frames, which bypass those queues. Signed-off-by: NFelix Fietkau <nbd@nbd.name> Signed-off-by: NJohannes Berg <johannes.berg@intel.com>
