This patch adds the Energy Efficient Ethernet support to the stmmac. Please see the driver's documentation for further details about this support in the driver. Thanks also goes to Rayagond Kokatanur for his first implementation. Note: to clearly manage and expose the lpi interrupt status and eee ethtool stats I've had to do some modifications to the driver's design and I found really useful to move other parts of the code (e.g. mmc irq stat) in the main directly. So this means that some core has been reworked to introduce the EEE. v1: initial patch v2: fixed some sparse issues (typos) v3: erroneously sent the v2 renamed as v3 v4: o Fixed the return value of the stmmac_eee_init as suggested by D.Miller o Totally reviewed the ethtool support for EEE o Added a new internal parameter to tune the SW timer for TX LPI. v5: do not change any eee setting in case of the stmmac_ethtool_op_set_eee fails (it has to return -EOPNOTSUPP in that case).

This patch adds a hook in the binding path of netlink. This is used by ctnetlink to allow module autoloading for the case in which one user executes: conntrack -E So far, this resulted in nfnetlink loaded, but not nf_conntrack_netlink. I have received in the past many complains on this behaviour. Signed-off-by:

This patch adds the following structure: struct netlink_kernel_cfg { unsigned int groups; void (*input)(struct sk_buff *skb); struct mutex *cb_mutex; }; That can be passed to netlink_kernel_create to set optional configurations for netlink kernel sockets. I've populated this structure by looking for NULL and zero parameters at the existing code. The remaining parameters that always need to be set are still left in the original interface. That includes optional parameters for the netlink socket creation. This allows easy extensibility of this interface in the future. This patch also adapts all callers to use this new interface.

John Linville says: ==================== Here is another batch of updates intended for 3.6. This includes a number of pulls, including ones from the mac80211, iwlwifi, ath6kl, and wl12xx trees. I also pulled from the wireless tree to avoid potential build conflicts. There are a number of other patches applied directly, including a number for the Broadcom drivers and the mwifiex driver. The updates cover the usual variety of new hardware support and feature enhancements. It's all good work, but there aren't any big headliners. This does resolve a net-next/wireless-next merge conflict reported by Stephen. ==================== Signed-off-by:

If rpfilter is off (or the SKB has an IPSEC path) and there are not tclassid users, we don't have to do anything at all when fib_validate_source() is invoked besides setting the itag to zero. We monitor tclassid uses with a counter (modified only under RTNL and marked __read_mostly) and we protect the fib_validate_source() real work with a test against this counter and whether rpfilter is to be done. Having a way to know whether we need no tclassid processing or not also opens the door for future optimized rpfilter algorithms that do not perform full FIB lookups. Signed-off-by:

At Facebook, we do Layer-3 DSR via IP-in-IP tunneling. Our load balancers wrap an extra IP header on incoming packets so they can be routed to the backend. In the v4 tunnel driver, when these packets fall on the default tunl0 device, the behavior is to decapsulate them and drop them back on the stack. So our setup is that tunl0 has the VIP and eth0 has (obviously) the backend's real address. In IPv6 we do the same thing, but the v6 tunnel driver didn't have this same behavior - if you didn't have an explicit tunnel setup, it would drop the packet. This patch brings that v4 feature to the v6 driver. The same IPv6 address checks are performed as with any normal tunnel, but as the fallback tunnel endpoint addresses are unspecified, the checks must be performed on a per-packet basis, rather than at tunnel configuration time.

After SKB is queued into tx_queue, it will be freed if request_gop is NULL. However, no dequeue action is called in this situation, it is likely that tx_queue constains freed SKB. This patch should fix this issue, and it is based on 3.5.0-rc4+. This issue is found through code inspection, no bug is seen with it currently. I run netperf test for several hours, and no network regression was found. Signed-off-by:

Neal Cardwell authored
The code in tcp_v6_conn_request() was implicitly assuming that tcp_v6_send_synack() would take care of dst_release(), much as tcp_v4_send_synack() already does. This resulted in tcp_v6_conn_request() leaking a dst if sysctl_tw_recycle is enabled. This commit restructures tcp_v6_send_synack() so that it accepts a dst pointer and takes care of releasing the dst that is passed in, to plug the leak and avoid future surprises by bringing the IPv6 behavior in line with the IPv4 side.

With the recent change (earlier in this patch series) to set flowi6_oif to treq->iif in inet6_csk_route_req(), the dst lookup in these two functions is now identical, so tcp_v6_send_synack() can now just call inet6_csk_route_req(), to reduce code duplication and keep things closer to the IPv4 side, which is structured this way.

This commit changes inet_csk_route_req() so that it uses a pointer to a struct flowi6, rather than allocating its own on the stack. This brings its behavior in line with its IPv4 cousin, inet_csk_route_req(), and allows a follow-on patch to fix a dst leak. Signed-off-by:

Fix inet6_csk_route_req() to use as the flowi6_oif the treq->iif, which is correctly fixed up in tcp_v6_conn_request() to handle the case of link-local addresses. This brings it in line with the tcp_v6_send_synack() code, which is already correctly using the treq->iif in this way. Signed-off-by:

The correct behavior is to program the interrupt coalescing regs (RXICr/TXICr) in accordance with the Rx/Tx Q's "rx/txcoalescing" flag. That is, if the coalescing flag is 0 for a given Rx/Tx queue then the corresponding coalescing register should be cleared. This behavior is correctly implemented for the single-queue mode (SQ_SG_MODE), but not for the multi-queue mode (MQ_MG_MODE). This fixes the later case. Signed-off-by:

usbnet_disconnect() will set intfdata to NULL before calling the minidriver unbind function. The cdc_wdm subdriver cannot know that it is disconnecting until the qmi_wwan unbind function has called its disconnect function. This means that we must be able to support the cdc_wdm subdriver operating normally while usbnet_disconnect() is running, and in particular that intfdata may be NULL. The only place this matters is in qmi_wwan_cdc_wdm_manage_power which is called from cdc_wdm. Simply testing for NULL intfdata there is sufficient to allow it to continue working at all times.

In commit 7a879824 we added a wrapper for the WDIOC_GETSTATUS ioctl call. The code results however in a different behaviour: it returns an error if the driver doesn't support the status operation. This is not according to the API that says that when we don't support the status operation, that we just should return a 0 value. Only when the device isn't there anymore, we should return an error.
