Since bd678e09 ("netfilter: nfnetlink: fix splat due to incorrect socket memory accounting in skbuff clones"), we don't manually attach the sk to the skbuff clone anymore, so we have to use the original skbuff from netlink_ack() which needs to access the sk pointer.

Ulrich reports soft lockup with following (shortened) callchain: NMI watchdog: BUG: soft lockup - CPU#1 stuck for 22s! __netif_receive_skb_core+0x6e4/0x774 process_backlog+0x94/0x160 net_rx_action+0x88/0x178 call_do_softirq+0x24/0x3c do_softirq+0x54/0x6c __local_bh_enable_ip+0x7c/0xbc nf_ct_iterate_cleanup+0x11c/0x22c [nf_conntrack] masq_inet_event+0x20/0x30 [nf_nat_masquerade_ipv6] atomic_notifier_call_chain+0x1c/0x2c ipv6_del_addr+0x1bc/0x220 [ipv6] Problem is that nf_ct_iterate_cleanup can run for a very long time since it can be interrupted by softirq processing. Moreover, atomic_notifier_call_chain runs with rcu readlock held. So lets call cond_resched() in nf_ct_iterate_cleanup and defer the call to a work queue for the atomic_notifier_call_chain case. We also need another cond_resched in get_next_corpse, since we have to deal with iter() always returning false, in that case get_next_corpse will walk entire conntrack table. Reported-by:

The nb8800_poll() function initializes the 'next' variable in the loop looking for new input data.

When CONFIG_PCI_MSI is disabled, we get warnings about unused functions in the vxge driver: drivers/net/ethernet/neterion/vxge/vxge-main.c:2121:13: warning: 'adaptive_coalesce_tx_interrupts' defined but not used [-Wunused-function] drivers/net/ethernet/neterion/vxge/vxge-main.c:2149:13: warning: 'adaptive_coalesce_rx_interrupts' defined but not used [-Wunused-function] We could add another #ifdef here, but it's nicer to avoid those warnings for good by converting the existing #ifdef to if(IS_ENABLED()), which has the same effect but provides better compile-time coverage in general, and lets the compiler understand better when the function is intentionally unused.

The bgmac driver depends on BCMA_HOST_SOC, which is only used when CONFIG_BCMA is enabled. However, it is a bool option and can be set when CONFIG_BCMA=m, and then bgmac can be built-in, leading to an obvious link error: drivers/built-in.o: In function `bgmac_init': :(.init.text+0x7f2c): undefined reference to `__bcma_driver_register' drivers/built-in.o: In function `bgmac_exit': :(.exit.text+0x110a): undefined reference to `bcma_driver_unregister' To avoid this case, we need to depend on both BCMA and BCMA_SOC, as this patch does. I'm also trying to make the dependency more readable by splitting it into three lines, and adding a COMPILE_TEST alternative so we can test-build it in all configurations that support BCMA. The added dependency on FIXED_PHY addresses a related issue where we cannot call fixed_phy_register() when CONFIG_FIXED_PHY=m and CONFIG_BGMAC=y. Signed-off-by:

The davinci_cpdma mixes up physical addresses as seen from the CPU and DMA addresses as seen from a DMA master, since it can operate on both normal memory or an on-chip buffer. If dma_addr_t is different from phys_addr_t, this means we get a compile-time warning about the type mismatch: ethernet/ti/davinci_cpdma.c: In function 'cpdma_desc_pool_create': ethernet/ti/davinci_cpdma.c:182:48: error: passing argument 3 of 'dma_alloc_coherent' from incompatible pointer type [-Werror=incompatible-pointer-types] pool->cpumap = dma_alloc_coherent(dev, size, &pool->phys, In file included from ethernet/ti/davinci_cpdma.c:21:0: dma-mapping.h:398:21: note: expected 'dma_addr_t * {aka long long unsigned int *}' but argument is of type 'phys_addr_t * {aka unsigned int *}' static inline void *dma_alloc_coherent(struct device *dev, size_t size, This slightly restructures the code so the address we use for mapping RAM into a DMA address is always a dma_addr_t, avoiding the warning. The code is correct even if both types are 32-bit because the DMA master in this device only supports 32-bit addressing anyway, independent of the types that are used. We still assign this value to pool->phys, and that is wrong if the driver is ever used with an IOMMU, but that value appears to be never used, so there is no problem really. I've added a couple of comments about where we do things that are slightly violating the API. Signed-off-by: -

Paolo Abeni says: ==================== ipv6: fix sticky pktinfo behaviour Currently: ip addr add dev eth0 2001:0010::1/64 ip addr add dev eth1 2001:0020::1/64 ping6 -I eth0 2001:0020::2 do not lead to the expected results, i.e. eth1 is used as the egress interface. This is due to two related issues in handling sticky pktinfo, used by ping6 to enforce the device binding: - ip6_dst_lookup_flow()/ip6_dst_lookup_tail() do not really enforce flowi6_oif match - ipv6 udp connect() just ignore flowi6_oif These patches address each issue individually. The kernel has never enforced the egress interface specified via the sticky pktinfo, except briefly between the commits 741a11d9 ("net: ipv6: Add RT6_LOOKUP_F_IFACE flag if oif is set") and d46a9d67 ("net: ipv6: Dont add RT6_LOOKUP_F_IFACE flag if saddr set"), but the ping6 tools was unaffected up to iputils-20100214, since before it used SO_BINDTODEVICE to enforce the egress interface. ==================== Signed-off-by:

The current implementation of ip6_dst_lookup_tail basically ignore the egress ifindex match: if the saddr is set, ip6_route_output() purposefully ignores flowi6_oif, due to the commit d46a9d67 ("net: ipv6: Dont add RT6_LOOKUP_F_IFACE flag if saddr set"), if the saddr is 'any' the first route lookup in ip6_dst_lookup_tail fails, but upon failure a second lookup will be performed with saddr set, thus ignoring the ifindex constraint. This commit adds an output route lookup function variant, which allows the caller to specify lookup flags, and modify ip6_dst_lookup_tail() to enforce the ifindex match on the second lookup via said helper. ip6_route_output() becames now a static inline function build on top of ip6_route_output_flags(); as a side effect, out-of-tree modules need now a GPL license to access the output route lookup functionality.

Currently the port based VLAN maps should be configured to allow every port to egress frames on all other ports, except themselves. The debugfs interface shows that they are misconfigured. For instance, a 7-port switch has the following content in the related register 0x06: GLOBAL GLOBAL2 SERDES 0 1 2 3 4 5 6 ... 6: 1fa4 1f0f 4 7f 7e 7d 7c 7b 7a 79 ... This means that port 3 is allowed to talk to port 2-6, but cannot talk to ports 0 and 1. With this fix, port 3 can correctly talk to all ports except 3 itself: GLOBAL GLOBAL2 SERDES 0 1 2 3 4 5 6 ... 6: 1fa4 1f0f 4 7e 7d 7b 77 6f 5f 3f ...

The fib_table_lookup function had a shift by 32 that triggered a UBSAN warning. This was due to the fact that I had placed the shift first and then followed it with the check for the suffix length to ignore the undefined behavior. If we reorder this so that we verify the suffix is less than 32 before shifting the value we can avoid the issue. Reported-by:

The moxart ethernet driver confuses coherent DMA buffers with MMIO registers. moxart_ether.c: In function 'moxart_mac_setup_desc_ring': moxart_ether.c:146:428: error: passing argument 1 of '__fswab32' makes integer from pointer without a cast [-Werror=int-conversion] moxart_ether.c:74:39: warning: incorrect type in argument 3 (different address spaces) moxart_ether.c:74:39: expected void *cpu_addr moxart_ether.c:74:39: got void [noderef] <asn:2>*tx_desc_base This leaves the basic logic alone and uses normal pointers for the virtual address of the descriptor. As we cannot use readl/writel to access them, we also introduce our own moxart_desc_read moxart_desc_write helpers that perform the same endianess swap as the original code, but without the address space conversion. The barriers are made explicit here where needed: Even in the worst-case scenario, we just have to use a rmb() after checking ownership so we don't read any input data before we are sure it is value, and we use wmb() before transferring ownership back to the device.

When CONFIG_PROC_FS, CONFIG_IP_PNP_BOOTP, CONFIG_IP_PNP_DHCP and CONFIG_IP_PNP_RARP are all disabled, we get a warning about the ic_proto_used variable being unused: net/ipv4/ipconfig.c:146:12: error: 'ic_proto_used' defined but not used [-Werror=unused-variable] This avoids the warning, by making the definition conditional on whether a dynamic IP configuration protocol is configured.

Currently when a macvlan is being initialized and the lower device is netif_carrier_ok(), the macvlan device doesn't run through rfc2863_policy() and is left with UNKNOWN operstate. Fix it by adding an unconditional linkwatch event for the new macvlan device. Similar fix is already used by the 8021q device (see register_vlan_dev()). Also fix the inconsistent state when the lower device has been down and its carrier was changed (when a device is down NETDEV_CHANGE doesn't get generated). The second issue can be seen f.e. when we have a macvlan on top of a 8021q device which has been down and its real device has been changing carrier states, after setting the 8021q device up, the macvlan device will have the same carrier state as it was before even though the 8021q can now have a different state. Example for case 1: 4: eth2: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP mode DEFAULT group default qlen 1000 $ ip l add l eth2 macvl0 type macvlan $ ip l set macvl0 up $ ip l sh macvl0 72: macvl0@eth2: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UNKNOWN mode DEFAULT group default link/ether f6:0b:54:0a:9d:a3 brd ff:ff:ff:ff:ff:ff Example for case 2 (order is important): Prestate: eth2 UP/CARRIER, vlan1 down, vlan1-macvlan down $ ip l set vlan1-macvlan up $ ip l sh vlan1-macvlan 71: vlan1-macvlan@vlan1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UNKNOWN mode DEFAULT group default link/ether 4a:b8:44:56:b9:b9 brd ff:ff:ff:ff:ff:ff [ eth2 loses CARRIER before vlan1 has been UP-ed ] $ ip l sh eth2 4: eth2: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast state DOWN mode DEFAULT group default qlen 1000 link/ether 52:54:00:bf:57:16 brd ff:ff:ff:ff:ff:ff $ ip l sh vlan1-macvlan 71: vlan1-macvlan@vlan1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UNKNOWN mode DEFAULT group default link/ether 4a:b8:44:56:b9:b9 brd ff:ff:ff:ff:ff:ff $ ip l set vlan1 up $ ip l sh vlan1 70: vlan1@eth2: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc noqueue state LOWERLAYERDOWN mode DEFAULT group default qlen 1000 link/ether 52:54:00:bf:57:16 brd ff:ff:ff:ff:ff:ff $ ip l sh vlan1-macvlan 71: vlan1-macvlan@vlan1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UNKNOWN mode DEFAULT group default link/ether 4a:b8:44:56:b9:b9 brd ff:ff:ff:ff:ff:ff vlan1-macvlan is still UP, still has carrier and is still in the same operstate as before. After the patch in case 1 macvl0 has state UP as it should and in case 2 vlan1-macvlan has state LOWERLAYERDOWN again as it should. Note that while the lower macvlan device is down their carrier and thus operstate can go out of sync but that will be fixed once the lower device goes up again. This behaviour seems to have been present since beginning of git history. Signed-off-by:Nikolay Aleksandrov <nikolay@cumulusnetworks.com> Signed-off-by:

In 'commit 7fe8097c ("tipc: fix nullpointer bug when subscribing to events")', we terminate the connection if the subscription creation fails. In the same commit, the subscription creation result was based on the value of the subscription pointer (set in the function) instead of the return code. Unfortunately, the same function tipc_subscrp_create() handles subscription cancel request. For a subscription cancellation request, the subscription pointer cannot be set. Thus if a subscriber has several subscriptions and cancels any of them, the connection is terminated. In this commit, we terminate the connection based on the return value of tipc_subscrp_create().

The commit cad20c27 was supposed to fix handling of devices first using public addresses and then switching to RPAs after pairing. Unfortunately it missed a couple of key places in the code. 1. When evaluating which devices should be removed from the existing white list we also need to consider whether we have an IRK for them or not, i.e. a call to hci_find_irk_by_addr() is needed. 2. In smp_notify_keys() we should not be requiring the knowledge of the RPA, but should simply keep the IRK around if the other conditions require it. Signed-off-by:
