Every active TXQ is assigned to a TID given through the SCD_CONFIG_CMD, and acts as an identifier in the FW. However, there may be cases this ownership needs to be changed. For example, in the following scenario: 1. TID x is owner of a queue 2. Due to a shortage of queues, TID y and z share with x 3. TID x becomes inactive and needs to be removed from the shared queue. In this scenario, if another queue is freed and traffic on x continues, we can't allocate it a new queue as long as it is the owner of the first queue. Support moving ownership of a TXQ to a different TID (same STA) without stopping the queue. Signed-off-by:Liad Kaufman <liad.kaufman@intel.com> Signed-off-by:

When working in DQA mode, if a queue is shared and a HW restart occurs, there might be a possible race condition between stations on the queues, and an existing queue might be left with no queues. To solve this, make sure in DQA mode to re-assign the same queues as before the HW restart. Signed-off-by:

When sending the SCD_QUEUE_CONFIG command, the queue is associated to a specific TID. If later there is a need to use this TID on a different queue instead, it first needs to be unassociated from the first queue. Keep track for every queue what TID is associated with it. Signed-off-by:

The 9000 hardware will de-aggregate AMSDUs. In the process it will copy the mac header "as is" to the new MPDUs. This means driver should allow the same PN for MPDUs originated from the same AMSDU. Do that by incrementing the PN only for the last MPDU in the sequence. Signed-off-by:

Tom Herbert says: ==================== strp: Stream parser for messages This patch set introduces a utility for parsing application layer protocol messages in a TCP stream. This is a generalization of the mechanism implemented of Kernel Connection Multiplexor. This patch set adapts KCM to use the strparser. We expect that kTLS can use this mechanism also. RDS would probably be another candidate to use a common stream parsing mechanism. The API includes a context structure, a set of callbacks, utility functions, and a data ready function. The callbacks include a parse_msg function that is called to perform parsing (e.g. BPF parsing in case of KCM), and a rcv_msg function that is called when a full message has been completed. For strparser we specify the return codes from the parser to allow the backend to indicate that control of the socket should be transferred back to userspace to handle some exceptions in the stream: The return values are: >0 : indicates length of successfully parsed message 0 : indicates more data must be received to parse the message -ESTRPIPE : current message should not be processed by the kernel, return control of the socket to userspace which can proceed to read the messages itself other < 0 : Error is parsing, give control back to userspace assuming that synchronization is lost and the stream is unrecoverable (application expected to close TCP socket) There is one issue I haven't been able to fully resolve. If parse_msg returns ESTRPIPE (wants control back to userspace) the parser may already have consumed some bytes of the message. There is no way to put bytes back into the TCP receive queue and tcp_read_sock does not allow an easy way to peek messages. In lieu of a better solution, we return ENODATA on the socket to indicate that the data stream is unrecoverable (application needs to close socket). This condition should only happen if an application layer message header is split across two skbuffs and parsing just the first skbuff wasn't sufficient to determine the that transfer to userspace is needed. This patch set contains: - strparser implementation - changes to kcm to use strparser - strparser.txt documentation v2: - Add copyright notice to C files - Remove GPL module license from strparser.c - Add report of rxpause v3: - Restore GPL module license - Use EXPORT_SYMBOL_GPL v4: - Removed unused function, changed another to be static as suggested by davem - Rewoked data_ready to be called from upper layer, no longer requires taking over socket data_ready callback as suggested by Lance Chao Tested: - Ran a KCM thrash test for 24 hours. No behavioral or performance differences observed. ==================== Signed-off-by: -

This patch introduces a utility for parsing application layer protocol messages in a TCP stream. This is a generalization of the mechanism implemented of Kernel Connection Multiplexor. The API includes a context structure, a set of callbacks, utility functions, and a data ready function. A stream parser instance is defined by a strparse structure that is bound to a TCP socket. The function to initialize the structure is: int strp_init(struct strparser *strp, struct sock *csk, struct strp_callbacks *cb); csk is the TCP socket being bound to and cb are the parser callbacks. The upper layer calls strp_tcp_data_ready when data is ready on the lower socket for strparser to process. This should be called from a data_ready callback that is set on the socket: void strp_tcp_data_ready(struct strparser *strp); A parser is bound to a TCP socket by setting data_ready function to strp_tcp_data_ready so that all receive indications on the socket go through the parser. This is assumes that sk_user_data is set to the strparser structure. There are four callbacks. - parse_msg is called to parse the message (returns length or error). - rcv_msg is called when a complete message has been received - read_sock_done is called when data_ready function exits - abort_parser is called to abort the parser The input to parse_msg is an skbuff which contains next message under construction. The backend processing of parse_msg will parse the application layer protocol headers to determine the length of the message in the stream. The possible return values are: >0 : indicates length of successfully parsed message 0 : indicates more data must be received to parse the message -ESTRPIPE : current message should not be processed by the kernel, return control of the socket to userspace which can proceed to read the messages itself other < 0 : Error is parsing, give control back to userspace assuming that synchronzation is lost and the stream is unrecoverable (application expected to close TCP socket) In the case of error return (< 0) strparse will stop the parser and report and error to userspace. The application must deal with the error. To handle the error the strparser is unbound from the TCP socket. If the error indicates that the stream TCP socket is at recoverable point (ESTRPIPE) then the application can read the TCP socket to process the stream. Once the application has dealt with the exceptions in the stream, it may again bind the socket to a strparser to continue data operations. Note that ENODATA may be returned to the application. In this case parse_msg returned -ESTRPIPE, however strparser was unable to maintain synchronization of the stream (i.e. some of the message in question was already read by the parser). strp_pause and strp_unpause are used to provide flow control. For instance, if rcv_msg is called but the upper layer can't immediately consume the message it can hold the message and pause strparser. Signed-off-by: -

While commit 9c706a49 ("net: ipconfig: fix use after free") avoids the use after free, the resulting code still ends up calling both the ic_setup_if() and ic_setup_routes() after calling ic_close_devs(), and access to the device is still required. Move the call to ic_close_devs() to the very end of the function. Signed-off-by:

WANG Cong authored
As pointed out by Jamal, an action could be shared by multiple filters, so we can't use list to chain them any more after we get rid of the original tc_action. Instead, we could just save pointers to these actions in tcf_exts, since they are refcount'ed, so convert the list to an array of pointers. The "ugly" part is the action API still accepts list as a parameter, I just introduce a helper function to convert the array of pointers to a list, instead of relying on the C99 feature to iterate the array.

Simon Wunderlich says: ==================== pull request for net-next: batman-adv 2016-08-16 This feature patchset is all about adding netlink support, which should supersede our debugfs configuration interface in the long run. It is especially necessary when batman-adv should be used in different namespaces, since debugfs can not differentiate between those. More specifically, the following changes are included: - Two fixes for namespace handling by Andrew Lunn, checking also the namespaces for parent interfaces, and supress debugfs entries for non-default netns - Implement various netlink commands for the new interface, by Matthias Schiffer, Andrew Lunn, Sven Eckelmann and Simon Wunderlich (13 patches): * routing algorithm list * hardif list * translation tables (local and global) * TTVN for the translation tables * originator and neighbor tables for B.A.T.M.A.N. IV and B.A.T.M.A.N. V * gateway dump functionality for B.A.T.M.A.N. IV and B.A.T.M.A.N.

Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates 2016-08-16 This series contains fixes to e1000e, igb, ixgbe and i40e. Kshitiz Gupta provides a fix for igb to resolve the PHY delay compensation math in several functions. Jarod Wilson provides a fix for e1000e which had to broken up into 2 patches, first is prepares the driver for expanding the list of NICs that have occasional ~10 hour clock jumps when being used for PTP. Second patch actually fixes i218 silicon which has been experiencing the clock jumps while using PTP. Alex provides 2 patches for ixgbe now that he is back at Intel. First fixes setting VLNCTRL.VFE bit, which was left unchanged in earlier patches which resulted in disabling VLAN filtering for all the VFs. Second corrects the support for disabling the VLAN tag filtering via the feature bit. Lastly, David fixes i40e which was causing a kernel panic when non-contiguous traffic classes or traffic classes not starting with TC0, were configured on a link partner switch. To fix this, changed the logic when determining the total number of TCs enabled. ==================== Signed-off-by: -

When packets enter the device they are classified to a priority group (PG) buffer based on their PCP value. After their egress port and traffic class are determined they are moved to the switch's shared buffer and await transmission, if: (Ingress{Port}.Usage < Thres && Ingress{Port,PG}.Usage < Thres && Egress{Port}.Usage < Thres && Egress{Port,TC}.Usage < Thres) || (Ingress{Port}.Usage < Min || Ingress{Port,PG} < Min || Egress{Port}.Usage < Min || Egress{Port,TC}.Usage < Min) Packets scheduled to transmission through CPU port (trapped to CPU) use traffic class 7, which has a zero maximum and minimum quotas. However, when such packets arrive from PG 0 they are admitted to the shared buffer as PG 0 has a non-zero minimum quota. Allow all packets to be trapped to the CPU - regardless of the PG they were classified to - by assigning a 10KB minimum quota for CPU port and TC7.

One of the conditions to generate an ICMP Redirect Message is that "the packet is being forwarded out the same physical interface that it was received from" (RFC 1812). Therefore, we need to be able to trap such packets and let the kernel decide what to do with them. For each RIF, enable the loop-back filter, which will raise the LBERROR trap whenever the ingress RIF equals the egress RIF.

Commit bbf2a475 ("mlxsw: spectrum: Initialize ports at the end of init sequence") moved ports initialization to the end of the init sequence, which means ports are the first to be removed during fini. Since the FDB delayed work is still active when ports are removed it's possible for it to process FDB notifications of inactive ports, resulting in a warning message. Fix that by marking ports as inactive only after unregistering them. The NETDEV_UNREGISTER event will invoke bridge's driver port removal sequence that will cause the FDB (and FDB notifications) to be flushed.
