2016-07-15net: phy: micrel: Add KSZ8041FTL fiber mode supportPhilipp Zabel
We can't detect the FXEN (fiber mode) bootstrap pin, so configure it via a boolean device tree property "micrel,fiber-mode". If it is enabled, auto-negotiation is not supported. The only available modes are 100base-fx (full duplex and half duplex). Signed-off-by: Philipp Zabel <p.zabel@pengutronix.de> Signed-off-by: David S. Miller <davem@davemloft.net>

2016-07-15Merge branch 'rds-enable-mprds'David S. Miller
Sowmini Varadhan says: ==================== RDS: TCP: Enable mprds for rds-tcp The third, and final, installment for mprds-tcp changes. In Patch 3 of this set, if the transport support t_mp_capable, we hash outgoing traffic across multiple paths. Additionally, even if the transport is MP capable, we may be peering with some node that does not support mprds, or supports a different number of paths. This necessitates RDS control plane changes so that both peers agree on the number of paths to be used for the rds-tcp connection. Patch 3 implements all these changes, which are documented in patch 5 of the series. Patch 1 of this series is a bug fix for a race-condition that has always existed, but is now more easily encountered with mprds. Patch 2 is code refactoring. Patches 4 and 5 are Documentation updates. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

2016-07-15RDS: TCP: avoid bad page reference in rds_tcp_listen_data_readySowmini Varadhan
As the existing comments in rds_tcp_listen_data_ready() indicate, it is possible under some race-windows to get to this function with the accept() socket. If that happens, we could run into a sequence whereby thread 1 thread 2 rds_tcp_accept_one() thread sets up new_sock via ->accept(). The sk_user_data is now sock_def_readable data comes in for new_sock, ->sk_data_ready is called, and we land in rds_tcp_listen_data_ready rds_tcp_set_callbacks() takes the sk_callback_lock and sets up sk_user_data to be the cp read_lock sk_callback_lock ready = cp unlock sk_callback_lock page fault on ready In the above sequence, we end up with a panic on a bad page reference when trying to execute (*ready)(). Instead we need to call sock_def_readable() safely, which is what this patch achieves.

Saeed Mahameed says: ==================== Mellanox 100G mlx5 Bulk flow statistics and SRIOV TC offloads This series from Amir and Or deals with two enhancements for the mlx5 TC offloads. The 1st two patches add bulk reading of flow counters. Few bulk counter queries are used instead of issuing thousands firmware commands per second to get statistics of all flows set to HW. The next patches add TC based SRIOV offloading to mlx5, as a follow up for the e-switch offloads mode and the VF representors. When the e-switch is set to the (new) "offloads" mode, we can now offload TC/flower drop and forward rules, the forward action we offload is TC mirred/redirect. The above is done by the VF representor netdevices exporting the setup_tc ndo where from there we're re-using and enhancing the existing mlx5 TC offloads sub-module which now works for both the NIC and the SRIOV cases.

2016-07-13sctp: allow GSO frags to access the chunk tooMarcelo Ricardo Leitner
SCTP will try to access original IP headers on sctp_recvmsg in order to copy the addresses used. There are also other places that do similar access to IP or even SCTP headers. But after 90017accff61 ("sctp: Add GSO support") they aren't always there because they are only present in the header skb. SCTP handles the queueing of incoming data by cloning the incoming skb and limiting to only the relevant payload. This clone has its cb updated to something different and it's then queued on socket rx queue. Thus we need to fix this in two moments. For rx path, not related to socket queue yet, this patch uses a partially copied sctp_input_cb to such GSO frags. This restores the ability to access the headers for this part of the code. Regarding the socket rx queue, it removes iif member from sctp_event and also add a chunk pointer on it. With these changes we're always able to reach the headers again. The biggest change here is that now the sctp_chunk struct and the original skb are only freed after the application consumed the buffer. Note however that the original payload was already like this due to the skb cloning. For iif, SCTP's IPv4 code doesn't use it, so no change is necessary. IPv6 now can fetch it directly from original's IPv6 CB as the original skb is still accessible. In the future we probably can simplify sctp_v*_skb_iif() stuff, as sctp_v4_skb_iif() was called but it's return value not used, and now it's not even called, but such cleanup is out of scope for this change.

2016-07-13Bluetooth: Add Authentication Failed reason to Disconnected Mgmt eventSzymon Janc
If link is disconnected due to Authentication Failure (PIN or Key Missing status) userspace will be notified about this with proper error code. Many LE profiles define "PIN or Key Missing" status as indication of remote lost bond so this allows userspace to take action on this. @ Device Connected: 88:63:DF:88:0E:83 (1) flags 0x0000 02 01 1a 05 03 0a 18 0d 18 0b 09 48 65 61 72 74 ...........Heart 20 52 61 74 65 Rate > HCI Event: Command Status (0x0f) plen 4 LE Read Remote Used Features (0x08|0x0016) ncmd 1 Status: Success (0x00) > ACL Data RX: Handle 3585 flags 0x02 dlen 11 ATT: Read By Group Type Request (0x10) len 6 Handle range: 0x0001-0xffff Attribute group type: Primary Service (0x2800) > HCI Event: LE Meta Event (0x3e) plen 12 LE Read Remote Used Features (0x04) Status: Success (0x00) Handle: 3585 Features: 0x01 0x00 0x00 0x00 0x00 0x00 0x00 0x00 LE Encryption < HCI Command: LE Start Encryption (0x08|0x0019) plen 28 Handle: 3585 Random number: 0x0000000000000000 Encrypted diversifier: 0x0000 Long term key: 26201cd479a0921b6f949f0b1fa8dc82 > HCI Event: Command Status (0x0f) plen 4 LE Start Encryption (0x08|0x0019) ncmd 1 Status: Success (0x00) > HCI Event: Encryption Change (0x08) plen 4 Status: PIN or Key Missing (0x06) Handle: 3585 Encryption: Disabled (0x00) < HCI Command: Disconnect (0x01|0x0006) plen 3 Handle: 3585 Reason: Authentication Failure (0x05) > HCI Event: Command Status (0x0f) plen 4 Disconnect (0x01|0x0006) ncmd 1 Status: Success (0x00) > HCI Event: Disconnect Complete (0x05) plen 4 Status: Success (0x00) Handle: 3585 Reason: Connection Terminated By Local Host (0x16) @ Device Disconnected: 88:63:DF:88:0E:83 (1) reason 4 @ Device Connected: C4:43:8F:A3:4D:83 (0) flags 0x0000 08 09 4e 65 78 75 73 20 35 ..Nexus 5 > HCI Event: Command Status (0x0f) plen 4 Authentication Requested (0x01|0x0011) ncmd 1 Status: Success (0x00) > HCI Event: Link Key Request (0x17) plen 6 Address: C4:43:8F:A3:4D:83 (LG Electronics) < HCI Command: Link Key Request Reply (0x01|0x000b) plen 22 Address: C4:43:8F:A3:4D:83 (LG Electronics) Link key: 080812e4aa97a863d11826f71f65a933 > HCI Event: Command Complete (0x0e) plen 10 Link Key Request Reply (0x01|0x000b) ncmd 1 Status: Success (0x00) Address: C4:43:8F:A3:4D:83 (LG Electronics) > HCI Event: Auth Complete (0x06) plen 3 Status: PIN or Key Missing (0x06) Handle: 75 @ Authentication Failed: C4:43:8F:A3:4D:83 (0) status 0x05 < HCI Command: Disconnect (0x01|0x0006) plen 3 Handle: 75 Reason: Remote User Terminated Connection (0x13) > HCI Event: Command Status (0x0f) plen 4 Disconnect (0x01|0x0006) ncmd 1 Status: Success (0x00) > HCI Event: Disconnect Complete (0x05) plen 4 Status: Success (0x00) Handle: 75 Reason: Connection Terminated By Local Host (0x16) @ Device Disconnected: C4:43:8F:A3:4D:83 (0) reason 4 Signed-off-by: Szymon Janc <szymon.janc@codecoup.pl> Signed-off-by: Johan Hedberg <johan.hedberg@intel.com>
