The X520 family of network devices, with the 82599 chip, support a small number of Intel-verified SFP+ modules on their NICs. To maintain stability and quality, the current devices restrict untested 3rd party SFP+ modules. This patch introduces a module parameter for ixgbe to allow these untested modules at the user's peril. It also includes a warning to the syslog alerting users that the modules aren't supported, and results may vary.

TCP RST mechanism is broken in TCP md5(RFC2385). When connection is gone, md5 key is lost, sending RST without md5 hash is deem to ignored by peer. This can be a problem since RST help protocal like bgp to fast recove from peer crash. In most case, users of tcp md5, such as bgp and ldp, have listener on both sides to accept connection from peer. md5 keys for peers are saved in listening socket. There are two cases in finding md5 key when connection is lost: 1.Passive receive RST: The message is send to well known port, tcp will associate it with listner. md5 key is gotten from listener. 2.Active receive RST (no sock): The message is send to ative side, there is no socket associated with the message. In this case, finding listener from source port, then find md5 key from listener. we are not loosing sercuriy here: packet is checked with md5 hash. No RST is generated if md5 hash doesn't match or no md5 key can be found. Signed-off-by: Shawn Lu <shawn.lu@ericsson.com> Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: David S.

We don't check for NULL consistently in __xfrm6_output(). If "x" were NULL here it would lead to an OOPs later. I asked Steffen Klassert about this and he suggested that we remove the NULL check.

This patch makes sure we use appropriate memory barriers before publishing tp->md5sig_info, allowing tcp_md5_do_lookup() being used from tcp_v4_send_reset() without holding socket lock (upcoming patch from Shawn Lu) Note we also need to respect rcu grace period before its freeing, since we can free socket without this grace period thanks to SLAB_DESTROY_BY_RCU Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Cc: Shawn Lu <shawn.lu@ericsson.com> Signed-off-by: David S.

There is no limit on number of MD5 keys an application can attach to a tcp socket. This patch adds a per tcp socket limit based on /proc/sys/net/core/optmem_max With current default optmem_max values, this allows about 150 keys on 64bit arches, and 88 keys on 32bit arches.

In order to be able to support proper RST messages for TCP MD5 flows, we need to allow access to MD5 keys without locking listener socket. This conversion is a nice cleanup, and shrinks size of timewait sockets by 80 bytes. IPv6 code reuses generic code found in IPv4 instead of duplicating it. Control path uses GFP_KERNEL allocations instead of GFP_ATOMIC. Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Cc: Shawn Lu <shawn.lu@ericsson.com> Signed-off-by: David S.

Add ability to return neighbour proxies list to caller if it sent full ndmsg structure and has NTF_PROXY flag set. Before this patch (and before iproute2 patches): $ ip neigh add proxy 2001::1 dev eth0 $ ip -6 neigh show $ After it and with applied iproute2 patches: $ ip neigh add proxy 2001::1 dev eth0 $ ip -6 neigh show 2001::1 dev eth0 proxy $ Compatibility with old versions of iproute2 is not broken, kernel checks for incoming structure size and properly works if old structure is came. [v2] * changed comments style. * removed useless line with continue and curly bracket. * changed incoming message size check from equal to more or equal.

This code is clearly unused, since it has a #error right in it. Given the vintage of sun3 hardware, it is probably safe to assume that there is little interest in adding new functionality to the driver now, so just delete the unused block of code.

This function returns the page offset of the buffer, which can be calculated based on either its DMA address or its virtual address. It used to use the virtual address and we would cast that to unsigned long, as anything smaller would result in a compiler warning. Now that it's using the DMA address we should use unsigned int, matching the return type. It is also unnecessary to use __force. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com>

The irq handler was a mess. See 7ab87ff4 ("via-rhine: move work from irq handler to softirq and beyond") for similar changes. One can notice: - all non-napi tasks are explicitely scheduled trough a single work queue. - hiding software tx queue start behind the rtl_hw_start method is mildly natural. Move it in the caller where needed. - as can be seen from the heavy use of bh disabling locks, the driver is not safe for irq context messages with netconsole. It is still quite usable for general messaging though. Tested ok with concurrent registers dump (ethtool -d) + background traffic + "echo t > /proc/sysrq-trigger". Tested with old PCI chipset, PCIe 8168 and 810x: - XID 0c900800 RTL8168evl/8111evl - XID 18000000 RTL8168b/8111b - XID 98000000 RTL8169sc/8110sc - XID 083000c0 RTL8168d/8111d - XID 081000c0 RTL8168d/8111d - XID 00b00000 RTL8105e - XID 04a00000 RTL8102e As a side note, the comments in f11a377b ("r8169: avoid losing MSI interrupts") does not seem completely clear: if I hack the driver further to stop acking the irq link event bit, MSI interrupts keep being delivered (RTL8168b/8111b, XID 18000000).
