In some rare configurations, we get a warning about the 'index' variable being used without an initialization: drivers/net/ethernet/rocker/rocker_ofdpa.c: In function ‘ofdpa_port_fib_ipv4.isra.16.constprop’: drivers/net/ethernet/rocker/rocker_ofdpa.c:2425:92: warning: ‘index’ may be used uninitialized in this function [-Wmaybe-uninitialized] This is a false positive, the logic is just a bit too complex for gcc to follow here. Moving the intialization of 'index' a little further down makes it clear to gcc that the function always returns an error if it is not initialized. Signed-off-by:

The hdr_offset variable is only if we deal with a TCP or UDP packet, but as the check surrounding its usage tests for skb_is_gso() instead, the compiler has no idea if the variable is initialized or not at that point: drivers/net/hyperv/netvsc_drv.c: In function ‘netvsc_start_xmit’: drivers/net/hyperv/netvsc_drv.c:494:42: error: ‘hdr_offset’ may be used uninitialized in this function [-Werror=maybe-uninitialized] This adds an additional check for the transport type, which tells the compiler that this path cannot happen. Since the get_net_transport_info() function should always be inlined here, I don't expect this to result in additional runtime checks. Signed-off-by:

gcc found a reference to an uninitialized variable in the error handling of bcm_enet_open, introduced by a recent cleanup: drivers/net/ethernet/broadcom/bcm63xx_enet.c: In function 'bcm_enet_open' drivers/net/ethernet/broadcom/bcm63xx_enet.c:1129:2: warning: 'phydev' may be used uninitialized in this function [-Wmaybe-uninitialized] This makes the use of that variable conditional, so we only reference it here after it has been used before. Unlike my normal patches, I have not build-tested this one, as I don't currently have mips test in my randconfig setup.

Satish reported a problem with the perm multicast router ports not getting reenabled after some series of events, in particular if it happens that the multicast snooping has been disabled and the port goes to disabled state then it will be deleted from the router port list, but if it moves into non-disabled state it will not be re-added because the mcast snooping is still disabled, and enabling snooping later does nothing. Here are the steps to reproduce, setup br0 with snooping enabled and eth1 added as a perm router (multicast_router = 2): 1. $ echo 0 > /sys/class/net/br0/bridge/multicast_snooping 2. $ ip l set eth1 down ^ This step deletes the interface from the router list 3. $ ip l set eth1 up ^ This step does not add it again because mcast snooping is disabled 4. $ echo 1 > /sys/class/net/br0/bridge/multicast_snooping 5. $ bridge -d -s mdb show <empty> At this point we have mcast enabled and eth1 as a perm router (value = 2) but it is not in the router list which is incorrect. After this change: 1. $ echo 0 > /sys/class/net/br0/bridge/multicast_snooping 2. $ ip l set eth1 down ^ This step deletes the interface from the router list 3. $ ip l set eth1 up ^ This step does not add it again because mcast snooping is disabled 4. $ echo 1 > /sys/class/net/br0/bridge/multicast_snooping 5. $ bridge -d -s mdb show router ports on br0: eth1 Note: we can directly do br_multicast_enable_port for all because the querier timer already has checks for the port state and will simply expire if it's in blocking/disabled. See the comment added by commit 9aa66382 ("bridge: multicast: add a comment to br_port_state_selection about blocking state") Fixes: 561f1103 ("bridge: Add multicast_snooping sysfs toggle") Reported-by:

After Jesper commit back in linux-3.18, we trigger a lockdep splat in proc_create_data() while allocating memory from pktgen_change_name(). This patch converts t->if_lock to a mutex, since it is now only used from control path, and adds proper locking to pktgen_change_name() 1) pktgen_thread_lock to protect the outer loop (iterating threads) 2) t->if_lock to protect the inner loop (iterating devices) Note that before Jesper patch, pktgen_change_name() was lacking proper protection, but lockdep was not able to detect the problem.

Currently, socket lookups for l3mdev (vrf) use cases can match a socket that is bound to a port but not a device (ie., a global socket). If the sysctl tcp_l3mdev_accept is not set this leads to ack packets going out based on the main table even though the packet came in from an L3 domain. The end result is that the connection does not establish creating confusion for users since the service is running and a socket shows in ss output. Fix by requiring an exact dif to sk_bound_dev_if match if the skb came through an interface enslaved to an l3mdev device and the tcp_l3mdev_accept is not set. skb's through an l3mdev interface are marked by setting a flag in inet{6}_skb_parm. The IPv6 variant is already set; this patch adds the flag for IPv4. Using an skb flag avoids a device lookup on the dif. The flag is set in the VRF driver using the IP{6}CB macros. For IPv4, the inet_skb_parm struct is moved in the cb per commit 971f10ec, so the match function in the TCP stack needs to use TCP_SKB_CB. For IPv6, the move is done after the socket lookup, so IP6CB is used. The flags field in inet_skb_parm struct needs to be increased to add another flag. There is currently a 1-byte hole following the flags, so it can be expanded to u16 without increasing the size of the struct.

Some crypto implementations (such as the generic CCM wrapper in crypto/) use scatterlists to map fields of private data in their struct aead_req. This means these data structures cannot live in the vmalloc area, which means that they cannot live on the stack (with CONFIG_VMAP_STACK.) This currently occurs only with the generic software implementation, but the private data and usage is implementation specific, so move the whole data structures off the stack into heap by allocating every time we need to use them. In addition, take care not to put any of our own stack allocations into scatterlists. This involves reserving some extra room when allocating the aead_request structures, and referring to those allocations in the scatter- lists (while copying the data from the stack before the crypto operation) Signed-off-by:

There is a race condition that can occur if EMAC interrupts are enabled when phy_disconnect() is called. phy_disconnect() sets adjust_link to NULL. When an interrupt occurs, the ISR might call phy_mac_interrupt(), which wakes up the workqueue function phy_state_machine(). This function might reference adjust_link, thereby causing a null pointer exception. Signed-off-by:

In cases where the number of tx rings is not a multiple of the number of rx rings, the tx completion event will be handled on a different core from the transmit and population of the ring. Races on the ring will lead to a double-free of the page, and possibly other corruption. The rings are initialized by default with a valid multiple of rings, based on the number of cpus, therefore an invalid configuration requires ethtool to change the ring layout. For instance 'ethtool -L eth0 rx 9 tx 8' will cause packets received on rx0, and XDP_TX'd to tx48, to be completed on cpu3 (48 % 9 == 3). Resolve this discrepancy by shifting the irq for the xdp tx queues to start again from 0, modulo rx_ring_num. Fixes: 9ecc2d86 ("net/mlx4_en: add xdp forwarding and data write support") Reported-by:

The qedr driver would require a tristate Kconfig option [to allow it to compile as a module], and toward that end we've added the INFINIBAND_QEDR option. But as we've made the compilation of the qed/qede infrastructure required for RoCE dependent on the option we'd be facing linking difficulties in case that QED=y or QEDE=y, and INFINIBAND_QEDR=m. To resolve this, we seperate between the INFINIBAND_QEDR option and the infrastructure support in qed/qede by introducing a new QED_RDMA option which would be selected by INFINIBAND_QEDR but would be a boolean instead of a tristate; Following that, the qed/qede is fixed based on this new option so that all config combinations would be supported.

Smatch compains about qed_roce_ll2_tx() dereference of the 'cdev' variable while testing its validity later. As the validation checking is an over-kill [variable would always be set], simply remove it. Reported-by:
