This commit fixes a long-standing bug that has been reported by many users: on some Armada 370 platforms, only the network interface that has been used in U-Boot to tftp the kernel works properly in Linux. The other network interfaces can see a 'link up', but are unable to transmit data. The reports were generally made on the Armada 370-based Mirabox, but have also been given on the Armada 370-RD board. The network MAC in the Armada 370/XP (supported by the mvneta driver in Linux) has a functionality that allows it to continuously poll the PHY and directly update the MAC configuration accordingly (speed, duplex, etc.). The very first versions of the driver submitted for review were using this hardware mechanism, but due to this, the driver was not integrated with the kernel phylib. Following reviews, the driver was changed to use the phylib, and therefore a software based polling. In software based polling, Linux regularly talks to the PHY over the MDIO bus, and sees if the link status has changed. If it's the case then the adjust_link() callback of the driver is called to update the MAC configuration accordingly. However, it turns out that the adjust_link() callback was not configuring the hardware in a completely correct way: while it was setting the speed and duplex bits correctly, it wasn't telling the hardware to actually take into account those bits rather than what the hardware-based PHY polling mechanism has concluded. So, in fact the adjust_link() callback was basically a no-op. However, the network happened to be working because on the network interfaces used by U-Boot for tftp on Armada 370 platforms because the hardware PHY polling was enabled by the bootloader, and left enabled by Linux. However, the second network interface not used for tftp (or both network interfaces if the kernel is loaded from USB, NAND or SD card) didn't had the hardware PHY polling enabled. This patch fixes this situation by: (1) Making sure that the hardware PHY polling is disabled by clearing the MVNETA_PHY_POLLING_ENABLE bit in the MVNETA_UNIT_CONTROL register in the driver ->probe() function. (2) Making sure that the duplex and speed selections made by the adjust_link() callback are taken into account by clearing the MVNETA_GMAC_AN_SPEED_EN and MVNETA_GMAC_AN_DUPLEX_EN bits in the MVNETA_GMAC_AUTONEG_CONFIG register. This patch has been tested on Armada 370 Mirabox, and now both network interfaces are usable after boot.

While implementing NAPI for the driver, I overlooked the race conditions where interrupt handler might have called napi_schedule_prep() before napi_enable() was called or after napi_disable() was called. If RX interrupt happens, this would cause the endless interrupts and messages like: sh-eth eth0: ignoring interrupt, status 0x00040000, mask 0x01ff009f. The interrupt wouldn't even be masked by the kernel eventually since the handler would return IRQ_HANDLED all the time. As a fix, move napi_enable() call before request_irq() call and napi_disable() call after free_irq() call. Signed-off-by:

In tcp_v6_do_rcv() code, when processing pkt options, we soley work on our skb clone opt_skb that we've created earlier before entering tcp_rcv_established() on our way. However, only in condition ... if (np->rxopt.bits.rxtclass) np->rcv_tclass = ipv6_get_dsfield(ipv6_hdr(skb)); ... we work on skb itself. As we extract every other information out of opt_skb in ipv6_pktoptions path, this seems wrong, since skb can already be released by tcp_rcv_established() earlier on. When we try to access it in ipv6_hdr(), we will dereference freed skb. [ Bug added by commit 4c507d28 ("net: implement IP_RECVTOS for IP_PKTOPTIONS") ] Signed-off-by:

Allocating skbs when sending out neighbour discovery messages currently uses sock_alloc_send_skb() based on a per net namespace socket and thus share a socket wmem buffer space. If a netdevice is temporarily unable to transmit due to carrier loss or for other reasons, the queued up ndisc messages will cosnume all of the wmem space and will thus prevent from any more skbs to be allocated even for netdevices that are able to transmit packets. The number of neighbour discovery messages sent is very limited, use of alloc_skb() bypasses the socket wmem buffer size enforcement while the manual call to skb_set_owner_w() maintains the socket reference needed for the IPv6 output path. This patch has orginally been posted by Eric Dumazet in a modified form. Signed-off-by:

Bug: error to get the previous BD entry. When the current BD is the first BD, the previous BD entry must be the last BD, not "bdp - 1" in current logic. V4: * Optimize fec_enet_get_nextdesc() for code clean. Replace "ex_new_bd - ring_size" with "ex_base". Replace "new_bd - ring_size" with "base". V3: * Restore the API name because David suggest to use fec_enet_ prefix for all function in fec driver. So, change next_bd() -> fec_enet_get_nextdesc() change pre_bd() -> fec_enet_get_prevdesc() * Reduce the two APIs parameters for easy to call. V2: * Add tx_ring_size and rx_ring_size to struct fec_enet_private. * Replace api fec_enet_get_nextdesc() with next_bd(). Replace api fec_enet_get_prevdesc() with pre_bd(). * Move all ring size check logic to next_bd() and pre_bd(), which simplifies the code redundancy. V1: * Add BD ring size check to get the previous BD entry in correctly. Reviewed-by:

Fix the mismatch in the DMA mapping and unmapping sizes for receive. The unmap size must be equal to the map size and should not be the actual received frame length. The map size should also be adjusted by the NET_IP_ALIGN size since the h/w buffer size (dma_buf_sz) includes this offset. Also, add a missing dma_mapping_error check in xgmac_rx_refill. Reported-by:

Fix xgmac_set_rx_mode to handle several conditions that were not handled correctly as Lennert Buytenhek describes: If we have, say, 100 unicast addresses, and 5 multicast addresses, the unicast address count check will evaluate to true, and set use_hash to true. The multicast address check will however evaluate to false, and use_hash won't be set to true again, and XGMAC_FRAME_FILTER_HMC won't be OR'd into XGMAC_FRAME_FILTER, but since use_hash was still true from the unicast check, netdev_for_each_mc_addr() will program the multicast addresses into the hash table instead of using the MAC address registers, but since the HMC bit wasn't set, the hash table won't be checked for multicast addresses on receive, and we'll stop receiving multicast packets entirely. Also, there is no code that zeroes out MAC address registers reg..31 at the end of this function, meaning that under the right conditions, unicast/multicast addresses that were previously in the filter but were then deleted won't be cleared out.

Since the xgmac transmit start and completion work locklessly, it is possible for xgmac_xmit to stop the tx queue after the xgmac_tx_complete has run resulting in the tx queue never being woken up. Fix this by ensuring that ring buffer index updates are visible and recheck the ring space after stopping the queue. Also fix an off-by-one bug where we need to stop the queue when the ring buffer space is equal to MAX_SKB_FRAGS. The implementation used here was copied from drivers/net/ethernet/broadcom/tg3.c.

The TX completion code may have freed an skb before the entire sg list was transmitted. The DMA unmap calls for the fragments could also get skipped. Now set the skb pointer on every entry in the ring, not just the head of the sg list. We then use the FS (first segment) bit in the descriptors to determine skb head vs. fragment. This also fixes similar bug in xgmac_free_tx_skbufs where clean-up of a sg list that wraps at the end of the ring buffer would not get unmapped. Signed-off-by:

Pull networking fixes from David Miller: 1) There was a simplification in the ipv6 ndisc packet sending attempted here, which avoided using memory accounting on the per-netns ndisc socket for sending NDISC packets. It did fix some important issues, but it causes regressions so it gets reverted here too. Specifically, the problem with this change is that the IPV6 output path really depends upon there being a valid skb->sk attached. The reason we want to do this change in some form when we figure out how to do it right, is that if a device goes down the ndisc_sk socket send queue will fill up and block NDISC packets that we want to send to other devices too. That's really bad behavior. Hopefully Thomas can come up with a better version of this change. 2) Fix a severe TCP performance regression by reverting a change made to dev_pick_tx() quite some time ago. From Eric Dumazet. 3) TIPC returns wrongly signed error codes, fix from Erik Hugne. 4) Fix OOPS when doing IPSEC over ipv4 tunnels due to orphaning the skb->sk too early. Fix from Li Hongjun. 5) RAW ipv4 sockets can use the wrong routing key during lookup, from Chris Clark. 6) Similar to #1 revert an older change that tried to use plain alloc_skb() for SYN/ACK TCP packets, this broke the netfilter owner mark which needs to see the skb->sk for such frames. From Phil Oester. 7) BNX2x driver bug fixes from Ariel Elior and Yuval Mintz, specifically in the handling of virtual functions. 8) IPSEC path error propagations to sockets is not done properly when we have v4 in v6, and v6 in v4 type rules.

Commit dc975382 "net: fec: add napi support to improve proformance" converted the fec driver to the napi model. However, that commit forgot to remove the call to skb_defer_rx_timestamp which is only needed in non-napi drivers. (The function napi_gro_receive eventually calls netif_receive_skb, which in turn calls skb_defer_rx_timestamp.) This patch should also be applied to the 3.9 and 3.10 kernels. Signed-off-by:

While looking into MLDv1/v2 code, I noticed that bridging code does not convert it's max delay into jiffies for MLDv2 messages as we do in core IPv6' multicast code. RFC3810, 5.1.3. Maximum Response Code says: The Maximum Response Code field specifies the maximum time allowed before sending a responding Report. The actual time allowed, called the Maximum Response Delay, is represented in units of milliseconds, and is derived from the Maximum Response Code as follows: [...] As we update timers that work with jiffies, we need to convert it.

If skb->len is too short then we should return an error. Otherwise we read beyond the end of skb->data for several bytes. Signed-off-by:

commit 8728c544 ("net: dev_pick_tx() fix") and commit b6fe83e9 ("bonding: refine IFF_XMIT_DST_RELEASE capability") are quite incompatible : Queue selection is disabled because skb dst was dropped before entering bonding device. This causes major performance regression, mainly because TCP packets for a given flow can be sent to multiple queues. This is particularly visible when using the new FQ packet scheduler with MQ + FQ setup on the slaves. We can safely revert the first commit now that 416186fb ("net: Split core bits of netdev_pick_tx into __netdev_pick_tx") properly caps the queue_index. Reported-by:

This reverts commit 1f324e38. It seems to cause regressions, and in particular the output path really depends upon there being a socket attached to skb->sk for checks such as sk_mc_loop(skb->sk) for example. See ip6_output_finish2(). Reported-by:

Since commit 3d7b46cd (ip_tunnel: push generic protocol handling to ip_tunnel module.), an Oops is triggered when an xfrm policy is configured on an IPv4 over IPv4 tunnel. xfrm4_policy_check() calls __xfrm_policy_check2(), which uses skb_dst(skb). But this field is NULL because iptunnel_pull_header() calls skb_dst_drop(skb). Signed-off-by:

Should a connect fail, if the publication/server is unavailable or due to some other error, a positive value will be returned and errno is never set. If the application code checks for an explicit zero return from connect (success) or a negative return (failure), it will not catch the error and subsequent send() calls will fail as shown from the strace snippet below. socket(0x1e /* PF_??? */, SOCK_SEQPACKET, 0) = 3 connect(3, {sa_family=0x1e /* AF_??? */, sa_data="\2\1\322\4\0\0\322\4\0\0\0\0\0\0"}, 16) = 111 sendto(3, "test", 4, 0, NULL, 0) = -1 EPIPE (Broken pipe) The reason for this behaviour is that TIPC wrongly inverts error codes set in sk_err.
