When building macb on x86_64 the following warnings show up: drivers/net/ethernet/cadence/macb.c: In function macb_interrupt: drivers/net/ethernet/cadence/macb.c:556:4: warning: large integer implicitly truncated to unsigned type [-Woverflow] drivers/net/ethernet/cadence/macb.c: In function macb_reset_hw: drivers/net/ethernet/cadence/macb.c:792:2: warning: large integer implicitly truncated to unsigned type [-Woverflow] drivers/net/ethernet/cadence/macb.c:793:2: warning: large integer implicitly truncated to unsigned type [-Woverflow] drivers/net/ethernet/cadence/macb.c:796:2: warning: large integer implicitly truncated to unsigned type [-Woverflow] Use -1 insted of ~0UL, as done in other places in the driver, to silence these warnings.

Each nexthop is added like a single route in the routing table. All routes that have the same metric/weight and destination but not the same gateway are considering as ECMP routes. They are linked together, through a list called rt6i_siblings. ECMP routes can be added in one shot, with RTA_MULTIPATH attribute or one after the other (in both case, the flag NLM_F_EXCL should not be set). The patch is based on a previous work from Luc Saillard <luc.saillard@6wind.com>. Signed-off-by: Nicolas Dichtel <nicolas.dichtel@6wind.com> Signed-off-by: David S. Miller <davem@davemloft.net>

A small host typically needs ~10 fib_info structures, so create initial hash table with 16 slots instead of only one. This removes potential false sharing and reallocs/rehashes (1->2->4->8->16) Signed-off-by: Eric Dumazet <edumazet@google.com> Signed-off-by: David S. Miller <davem@davemloft.net>

RFC 5961 5.2 [Blind Data Injection Attack].[Mitigation] All TCP stacks MAY implement the following mitigation. TCP stacks that implement this mitigation MUST add an additional input check to any incoming segment. The ACK value is considered acceptable only if it is in the range of ((SND.UNA - MAX.SND.WND) <= SEG.ACK <= SND.NXT). All incoming segments whose ACK value doesn't satisfy the above condition MUST be discarded and an ACK sent back. Move tcp_send_challenge_ack() before tcp_ack() to avoid a forward declaration.

The SO_BINDTODEVICE option is the only SOL_SOCKET one that can be set, but cannot be get via sockopt API. The only way we can find the device id a socket is bound to is via sock-diag interface. But the diag works only on hashed sockets, while the opt in question can be set for yet unhashed one. That said, in order to know what device a socket is bound to (we do want to know this in checkpoint-restore project) I propose to make this option getsockopt-able and report the respective device index. Another solution to the problem might be to teach the sock-diag reporting info on unhashed sockets. Should I go this way instead?

Joachim Eastwood says; ==================== This patch series prepares the old at91_ether driver for code sharing with the macb driver. The hardware is similar except for DMA TX/RX, so its not quite clear if it is practical to support both in one driver. But stuff like MDIO and statistics should be possible to share. Patch 1 adds some register defines and bits that is only found on RM9200. Patch 2-4 uses the register defines and access functions from the macb header. These can be squashed if it cause too much churn. Patch 5 merges the private at91_ether struct with the private macb struct. This makes it easier to later share code with the macb. The private macb struct becomes quite large, but most at91_ether specific members are removed in later patches. Patch 8 make macb compile when we select at91_ether. Is this approach okey? Patch 9 makes use of MDIO code from macb. This rips out the private phy handling code in at91_ether. One thing that is lost is the interrupt support for phy. But this should easy to add to macb which will then benefit both drivers. Patch 10 makes use of the macb_set_rx_mode from macb. Patch 11-12 makes at91_ether share the rx dma struct members from macb. Patch also moves the rx buffer allocation into netdev open and dealloc into netdev close. Last patch remove the now unused rm9200 emac header from include/mach. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

This rips out the at91_ether phy handling and ethtool stuff and replace it with equivalent stuff from macb. The only thing lost is the phy irq support from at91_ether, but this can be added to macb and then benefit all users. Signed-off-by: Joachim Eastwood <manabian@gmail.com>
