Hariprasad Shenai says: ==================== cxgb4: minor fixes, decode msgs and code refactor for few functions This patch series adds new routine to get adapter information and removes some redundant messages logged in dmesg. Fixes race while freeing tx descriptors. Decodes module type and link down reason codes obtained from firmware. Refactor port initialization and FW_PORT_CMD handling. Pass correct port id in DCB message handler to obtain netdev associated. This patch series has been created against net-next tree and includes patches on cxgb4 driver. We have included all the maintainers of respective drivers. Kindly review the change and let us know in case of any review comments. ==================== Signed-off-by:David S.

The firmware can send a set of asynchronous replies through FW_PORT_CMD with DCBX information when that's negotiated with the Link Peer. The old code always assumed that a FW_PORT_CMD reply was always a Get Port Information message. This change conditionalizes the code to only handle the Get Port Information messages and throws a warning if we don't understand what we've been given. Also refactor t4_handle_fw_rpl() so that core functionality performed by t4_handle_get_port_info() for a specified port. Signed-off-by:

There could be race between t4_eth_xmit() and t4_free_sge_resources() while freeing tx descriptors, take txq lock in t4_free_sge_resources(). We need to stop the xmit frame path which runs in bottom half context while unloading the driver using _bh variant of the lock. This is to prevent the deadlock between xmit and driver unload.

Nicolas Dichtel says: ==================== netlink: align attributes when needed (patchset #3) This is the continuation (series #3) of the work done to align netlink attributes when these attributes contain some 64-bit fields. It's the last patchset from what I've seen. The last user of nla_put_u64() is block/drbd. This module does not use standard netlink API (see all the stuff in include/linux/genl_magic_struct.h and include/linux/genl_magic_func.h). I didn't modify it because it's seems hard to do it whithout testing and fully understanding the context (for example, why include/linux/drbd_genl.h is not part of uapi?). Any thoughts? ==================== Signed-off-by: -

Tom Herbert says: ==================== ila: Support for checksum neutral translations This patch set updates ILA to support draft-herbert-nvo3-ila-02. The primary addition is support checksum neutral ILA translation. This allows address to be performed and still keep any transport layer checksums that include the addresses in their pseudo header to still be correct without the translator needing to parse L4. Other items are: - Structures for ILA addresses, identifiers, locators - Disallow translation on non-ILA addresses (check by type in identifier). - Change xlat (nf_input) to translates solely based on matching locators not identifiers (since identifiers are not obfuscated by checksum neutral). - Side effect if above is that multiple ILA domains are supported. Each local locator can map to a different SIR address (ILA domain), and each domain defines its own identifier space. Tested: Ran TCP_RR with 200 cnxs. ILA performance is slightly better than previously since we are not longer parsing L4 for checksum handling. I amd seeing about 1% performance overhead. Also ran TCP_STREAM and tested non-ILA address (type=0) are not translated. v2: Fix compilation errors ==================== Signed-off-by: -

Support checksum neutral ILA as described in the ILA draft. The low order 16 bits of the identifier are used to contain the checksum adjustment value. The csum-mode parameter is added to described checksum processing. There are three values: - adjust transport checksum (previous behavior) - do checksum neutral mapping - do nothing On output the csum-mode in the ila_params is checked and acted on. If mode is checksum neutral mapping then to mapping and set C-bit. On input, C-bit is checked. If it is set checksum-netural mapping is done (regardless of csum-mode in ila params) and C-bit will be cleared. If it is not set then action in csum-mode is taken. Signed-off-by:

Change model of xlat to be used only for input where lookup is done on the locator part of an address (comparing to locator_match as key in rhashtable). This is needed for checksum neutral translation which obfuscates the low order 16 bits of the identifier. It also permits hosts to be in muliple ILA domains (each locator can map to a different SIR address). A check is also added to disallow translating non-ILA addresses (check of type in identifier).

Add structures for identifiers, locators, and an ila address which is composed of a locator and identifier and in6_addr can be cast to it. This includes a three bit type field and enums for the types defined in ILA I-D. In ILA lwt don't allow user to set a translation for a non-ILA address (type of identifier is zero meaning it is an IID). This also requires that the destination prefix is at least 65 bytes (64 bit locator and first byte of identifier). Signed-off-by:

This patch parse port-idx-in-ae in enet node. In NIC mode of DSAF, all 6 PHYs of service DSAF are taken as ethernet ports to the CPU. The port-idx-in-ae can be 0 to 5. Here is the diagram: +-----+---------------+ | CPU | +-+-+-+---+-+-+-+-+-+-+ | | | | | | | | debug debug service port port port (0) (0) (0-5) In Switch mode of DSAF, all 6 PHYs of service DSAF are taken as physical ports connect to a LAN Switch while the CPU side assume itself have one single NIC connect to this switch. In this case, the port-idx-in-ae will be 0 only. +-----+-----+------+------+ | CPU | +-+-+-+-+-+-+-+-+-+-+-+-+-+ | | service| port(0) debug debug +------------+ port port | switch | (0) (0) +-+-+-+-+-+-++ | | | | | | external port when port-idx-in-ae is not exists, old attribute port-id will be used (only for compatible purpose, not recommended to use port-id in new code).

The memcpy of ipv6 header destination address to the skb control block (sbk->cb) in header_create() results in currupted memory when bt_xmit() is issued. The skb->cb is "released" in the return of header_create() making room for lower layer to minipulate the skb->cb. The value retrieved in bt_xmit is not persistent across header creation and sending, and the lower layer will overwrite portions of skb->cb, making the copied destination address wrong. The memory corruption will lead to non-working multicast as the first 4 bytes of the copied destination address is replaced by a value that resolves into a non-multicast prefix. This fix removes the dependency on the skb control block between header creation and send, by moving the destination address memcpy to the send function path (setup_create, which is called from bt_xmit).

Sowmini Varadhan says: ==================== pskb_extract() helper function. This patchset follows up on the discussion in https://www.mail-archive.com/netdev@vger.kernel.org/msg105090.html For RDS-TCP, we have to deal with the full gamut of nonlinear sk_buffs, including all the frag_list variants. Also, the parent skb has to remain unchanged, while the clone is queued for Rx on the PF_RDS socket. Patch 1 of this patchset adds a pskb_extract() function that does all this without the redundant memcpy's in pskb_expand_head() and __pskb_pull_tail(). v2: Marcelo Leitner review comments ==================== Signed-off-by:
