That way we don't have to reinstantiate another nf_hook_state on the stack of the nf_reinject() path. Signed-off-by:David S. Miller <davem@davemloft.net>

David S. Miller authored
Instead of passing a large number of arguments down into the nf_hook() entry points, create a structure which carries this state down through the hook processing layers. This makes is so that if we want to change the types or signatures of any of these pieces of state, there are less places that need to be changed. Signed-off-by:

Stas Sergeev says: ==================== mvneta: SGMII-based in-band link state signaling Currently the fixed-link DT binding is pre-configured and cannot be changed in run-time. This means the cable unplug events are not being detected, and the link parameters can't be negotiated. The following patches are needed when mvneta is used in fixed-link mode (without MDIO). They add an API to fixed_phy that allows to update status, and use that API in the mvneta driver when parsing the SGMII in-band status. There is also another implementation that doesn't add any API and does everything in mvneta driver locally: https://lkml.org/lkml/2015/3/31/327 I'll let people decide which approach is better. No strong opinion on my side. ==================== Signed-off-by:

When MDIO bus is unavailable (common setup for SGMII), the in-band signaling must be used to correctly track link state. This patch enables the in-band status delivery for link state changes, namely: - link up/down - link speed - duplex full/half fixed_phy_update_state() is used to update phy status.

Currently fixed_phy uses a callback to periodically poll the link state. This patch adds the fixed_phy_update_state() API. It solves the following problems: - On link state interrupt, MAC driver can't update status. Instead it needs to provide the callback to periodically query the HW about the link state. It is more efficient to update status after interrupt. - The callback needs to be unregistered before phy_disconnect(), or otherwise it will be called with net_dev==NULL. phy_disconnect() does not have enough info to unregister the callback automatically. - The callback needs to be registered before of_phy_connect() to avoid running with outdated state, but of_phy_connect() returns the phy_device pointer, which is needed to register the callback. Registering it before of_phy_connect() will therefore require a hack to get the pointer earlier. Overall, this addition makes the subsequent patch that implements SGMII link status for mvneta, much cleaner.

This adds the ability to read out the skb->priority from an eBPF program, so that it can be taken into account from a tc filter or action for the use-case where the priority is not being used to directly override the filter classification in a qdisc, but to tag traffic otherwise for the classifier; the priority can be assigned from various places incl. user space, in future we may also mangle it from an eBPF program.

Looking over the implementation for jhash2 and comparing it to jhash_3words I realized that the two hashes were in fact very different. Doing a bit of digging led me to "The new jhash implementation" in which lookup2 was supposed to have been replaced with lookup3. In reviewing the patch I noticed that jhash2 had originally initialized a and b to JHASH_GOLDENRATIO and c to initval, but after the patch a, b, and c were initialized to initval + (length << 2) + JHASH_INITVAL. However the changes in jhash_3words simply replaced the initialization of a and b with JHASH_INITVAL. This change corrects what I believe was an oversight so that a, b, and c in jhash_3words all have the same value added consisting of initval + (length << 2) + JHASH_INITVAL so that jhash2 and jhash_3words will now produce the same hash result given the same inputs.

Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates 2015-04-03 This series contains updates to i40e and i40evf only. Anjali provides a fix for verifying outer UDP receive checksum. Also adds helpful information to display when figuring out the cause of HMC errors. Mitch provides a fix to prevent a malicious or buggy VF driver from sending an invalid index into the VSI array which could panic the host. Cleans up the code where a function was moved, but the message did not follow. Adds protection to the VLAN filter list, same as the MAC filter list, to protect from corruption if the watchdog happens to run at the same time as a VLAN filter is being added/deleted. Jesse changes several memcpy() statements to struct assignments which are type safe and preferable. Fixed a bug when skb allocation fails, where we should not continue using the skb pointer. Also fixed a void function in FCoE which should not be returning anything. Greg fixes both i40e and i40evf to set the Ethernet protocol correctly when transmit VLAN offloads are disabled. Shannon fixes up VLAN messages when ports are added or removed, which were giving bogus index info. Also aligned the message text style with other messages in the driver. ==================== Signed-off-by: -

Ian Morris says: ==================== ipv4: coding style - comparisons with NULL Per the suggestion of Joe Perches, attached is a patch which aligns the coding style in ipv4 for comparisons with NULL. The code uses multiple different styles when comparing with NULL (I.e. x == NULL and !x as well as x != NULL and x). Generally the latter form is preferred in netdev and so this changes aligns the code to this style. ==================== Signed-off-by: -

This does not affect the Virtual channel API as such but it changes the meaning of what is communicated to the VSI resource struct as vsi_id. Earlier vsi_idx was being passed in, which was the index in the PF's VSI array. Now we pass vsi_id as communicated by the FW to the driver. This will help with future expansion of VF and FW communication. With this in place now the VF and Virtual channel driver change to move over to VSI id use is complete and is validated.

When the VXLAN ports are added and removed, the messaging was giving some bogus index info, the port was always '0' for the delete, and the message text style didn't match other messages in the driver. Also, there was an over-use of the tertiary statement which made reading a little harder than necessary. Change-ID: Ie805182a697b8b4c12024403ada87fd4e4fa2358 Signed-off-by:
