Changes to the global configuration updates like settings, class of device, name etc. can be received by every user. They are allowed to read them in the first place so provide the updates via events as well. Otherwise untrusted users start polling for updates and that is not a desired behavior. Signed-off-by:

Until now the management interface was restricted to CAP_NET_ADMIN. With this change every user can open the management socket. However the list of commands is heavily restricted to getting basic information about the attached controllers. No access for configuration or other operation is provided. The events are also limited. This is done so that no keys can leak or untrusted users can mess with the Bluetooth configuration. Signed-off-by:

The hci_send_to_flagged_channel helper function can be used to send packets to all channels that have a certain HCI socket flag set. This is especially useful for managment events that are limited to sockets that have first enabled certain functionality. This allows for filtering of events without confusing existing users.

Commit cd28a1a9 ("net: dsa: fully divert PHY reads/writes if requested") introduced a check for particular PHYs that need to be accessed using the slave MII bus created by DSA, but this check was too inclusive. This would prevent fixed PHYs from being successfully registered because those should not go through the slave MII bus created by DSA. Make sure we check that the PHY is not a fixed PHY to prevent that from happening. Fixes: cd28a1a9 ("net: dsa: fully divert PHY reads/writes if requested") Signed-off-by:

Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates 2015-03-13 This series contains updates to ixgbe and ixgbevf. Don adds additional support for X550 MAC types, which require additional steps around enabling and disabling Rx. Also cleans up variable type inconsistency. I provide a patch to allow relaxed ordering to be enabled on SPARC architectures. Also cleans up ixgbevf whitespace and code comments to align the driver with networking coding standard. Lastly cleaned up uses of memcpy() where ether_addr_copy() could have been used. Alex removes some dead code in the ixgbe cleanup patch. ==================== Signed-off-by: -

inet_sk_diag_fill() only copes with non timewait and non request socks Signed-off-by:
-
Eric Dumazet authored
Once request socks will be in ehash table, they will need to have a valid ir_iff field. This is currently true only for IPv6. This patch extends support for IPv4 as well. This means inet_diag_fill_req() can now properly use ir_iif, which is better for IPv6 link locals anyway, as request sockets and established sockets will propagate consistent netlink idiag_if.

Jon Maloy says: ==================== tipc: some optimizations and impovements The commits in this series contain some relatively simple changes that lead to better throughput across TIPC connections. We also make changes to the implementation of link transmission queueing and priority handling, in order to make the code more comprehensible and maintainable. v2: Commit #2: Redesigned tipc_msg_validate() to use pskb_may_pull(), as per feedback from David Miller. Commit #3: Some cosmetic changes to tipc_msg_extract(). I tried to replace the unconditional skb_linearize() with calls to pskb_may_pull() at selected locations, but I gave up. First, skb_trim() requires a fully linearized buffer. Second, it doesn't make much sense; the whole buffer will end up linearized, one way or another. ==================== Signed-off-by: -

Messages transferred by TIPC are assigned an "importance priority", -an integer value indicating how to treat the message when there is link or destination socket congestion. There is no separate header field for this value. Instead, the message user values have been chosen in ascending order according to perceived importance, so that the message user field can be used for this. This is not a good solution. First, we have many more users than the needed priority levels, so we end up with treating more priority levels than necessary. Second, the user field cannot always accurately reflect the priority of the message. E.g., a message fragment packet should really have the priority of the enveloped user data message, and not the priority of the MSG_FRAGMENTER user. Until now, we have been working around this problem in different ways, but it is now time to implement a consistent way of handling such priorities, although still within the constraint that we cannot allocate any more bits in the regular data message header for this. In this commit, we define a new priority level, TIPC_SYSTEM_IMPORTANCE, that will be the only one used apart from the four (lower) user data levels. All non-data messages map down to this priority. Furthermore, we take some free bits from the MSG_FRAGMENTER header and allocate them to store the priority of the enveloped message. We then adjust the functions msg_importance()/msg_set_importance() so that they read/set the correct header fields depending on user type. This small protocol change is fully compatible, because the code at the receiving end of a link currently reads the importance level only from user data messages, where there is no change.

struct tipc_link contains one single queue for outgoing packets, where both transmitted and waiting packets are queued. This infrastructure is hard to maintain, because we need to keep a number of fields to keep track of which packets are sent or unsent, and the number of packets in each category. A lot of code becomes simpler if we split this queue into a transmission queue, where sent/unacknowledged packets are kept, and a backlog queue, where we keep the not yet sent packets. In this commit we do this separation. Reviewed-by:

The unicast packet header contains a broadcast acknowledge sequence number, that may need to be conveyed to the broadcast link for proper treatment. Currently, the function tipc_rcv(), which is on the most critical data path, calls the function tipc_bclink_acknowledge() to have this done. This call is made for each received packet, and results in the unconditional grabbing of the broadcast link spinlock. This is unnecessary, since we can see directly from tipc_rcv() if the acknowledged number differs from what has been previously acked from the node in question. In the vast majority of cases the numbers won't differ, and there is nothing to update. We now make the call to tipc_bclink_acknowledge() conditional to that the two ack values differ. Reviewed-by:

When we currently extract a bundled buffer from a message bundle in the function tipc_msg_extract(), we allocate a new buffer and explicitly copy the linear data area. This is unnecessary, since we can just clone the buffer and do skb_pull() on the clone to move the data pointer to the correct position. This is what we do in this commit. Reviewed-by:

Currently, TIPC linearizes all incoming buffers directly at reception before passing them upwards in the stack. This is clearly a waste of CPU resources, and must be avoided. In this commit, we eliminate this unnecessary linearization. We still ensure that at least the message header is linear, and that the buffer is linearized where this is still needed, i.e. when unbundling and when reversing messages. In addition, we ensure that fragmented messages are validated after reassembly before delivering them upwards in the stack. Reviewed-by:

The function link_buf_validate() is in reality re-entrant and context independent, and will in later commits be called from several locations. Therefore, we move it to msg.c, make it outline and rename the it to tipc_msg_validate(). We also redesign the function to make proper use of pskb_may_pull() Signed-off-by:

The TIPC protocol spec has defined a 13 bit capability bitmap in the neighbor discovery header, as a means to maintain compatibility between different code and protocol generations. Until now this field has been unused. We now introduce the basic framework for exchanging capabilities between nodes at first contact. After exchange, a peer node's capabilities are stored as a 16 bit bitmap in struct tipc_node. Reviewed-by:

This patch adds a handling for calibration if we are 5 minutes in PLL state. I first tried to implement the calibration functionality in TX_ON state via register values CF_START and DCU_START, but this occurs a one second delay at each calibration time. An another solution to start a calibration is to switch from TRX_OFF state into TX_ON, then a calibration is done automatically by transceiver. This method will be used in this patch, after each transmit of a frame we check with jiffies if the PLL is set 5 minutes without doing a TRX_OFF->(TX_ON || RX_AACK_ON) or channel switch. The worst case would be a transceiver in receiving mode only, but this is under normal operation very unlikely. Signed-off-by:

This patch replace the state change timing relevant sleeps with hrtimers. Currently the sleeps are done in the complete handler of spi_async. The relation of doing the state change timing sleep with a timer will get the sleep functionality out of spi_async complete handler context. Signed-off-by:

This patch initialize xtal_trim value to zero. The xtal_trim property is an optional device tree value. Currently if no xtal_trim property is given the xtal_trim value can be contain random data, because it's a stack variable. This patch init the xtal_trim value to zero which is also the default value after reset for at86rf230 transceivers. Signed-off-by:

This patch fix the max sifs size correction when the IEEE802154_HW_TX_OMIT_CKSUM flag is set. With this flag the sk_buff doesn't contain the CRC, because the transceiver will add the CRC while transmit. Also add some defines for the max sifs frame size value and frame check sequence according to 802.15.4 standard. Signed-off-by:

Currently there exists two interface types with ARPHRD_IEEE802154. These are the 802.15.4 interfaces and 802.15.4 6LoWPAN interfaces. This is more a bug because some userspace applications checks on this value like wireshark. This occurs that wireshark will always try to parse a lowpan interface as 802.15.4 frames. With ARPHRD_6LOWPAN wireshark will parse it as IPv6 frames which is correct. Much applications checks on this value to readout the EUI64 mac address which should be the same for ARPHRD_6LOWPAN. BTLE 6LoWPAN and ieee802154 6LoWPAN will share now the same ARPHRD. Signed-off-by:
