2016-10-31ptp: use permission-specific DEVICE_ATTR variantsJulia Lawall1-1/+1
Use DEVICE_ATTR_RO for read only attributes. This simplifies the source code, improves readbility, and reduces the chance of inconsistencies. The semantic patch that makes this change is as follows: (http://coccinelle.lip6.fr/) // <smpl> @ro@ declarer name DEVICE_ATTR; identifier x,x_show; @@ DEVICE_ATTR(x, \(0444\|S_IRUGO\), x_show, NULL); @script:ocaml@ x << ro.x; x_show << ro.x_show; @@ if not (x^"_show" = x_show) then Coccilib.include_match false @@ declarer name DEVICE_ATTR_RO; identifier ro.x,ro.x_show; @@ - DEVICE_ATTR(x, \(0444\|S_IRUGO\), x_show, NULL); + DEVICE_ATTR_RO(x); // </smpl> Signed-off-by: Julia Lawall <Julia.Lawall@lip6.fr> Acked-by: Richard Cochran <richardcochran@gmail.com> Signed-off-by: David S.

2016-10-31ldmvsw: tx queue stuck in stopped state after LDC resetAaron Young1-3/+13
The following patch fixes an issue with the ldmvsw driver where the network connection of a guest domain becomes non-functional after the guest domain has panic'd and rebooted. The root cause was determined to be from the following series of events: 1. Guest domain panics - resulting in the guest no longer processing network packets (from ldmvsw driver) 2. The ldmvsw driver (in the control domain) eventually exerts flow control due to no more available tx drings and stops the tx queue for the guest domain 3. The LDC of the network connection for the guest is reset when the guest domain reboots after the panic. 4. The LDC reset event is received by the ldmvsw driver and the ldmvsw responds by clearing the tx queue for the guest. 5. ldmvsw waits indefinitely for a DATA ACK from the guest - which is the normal method to re-enable the tx queue. But the ACK never comes because the tx queue was cleared due to the LDC reset. To fix this issue, in addition to clearing the tx queue, re-enable the tx queue on a LDC reset. This prevents the ldmvsw from getting caught in this deadlocked state of waiting for a DATA ACK which will never come.

2016-10-31driver: tun: Use new macro SOCK_IOC_TYPE instead of literal number 0x89Gao Feng1-1/+1

Needed for both net and rdma subsystems. Updates and Fixes: From Saeed Mahameed (2): - mlx5 IB: Skip handling unknown mlx5 events - Add ConnectX-5 PCIe 4.0 VF device ID From Artemy Kovalyov (2): - Update struct mlx5_ifc_xrqc_bits - Ensure SRQ physical address structure endianness From Eugenia Emantayev (1): - Fix length of async_event_mask New Features: From Mohamad Haj Yahia (3): mlx5 SRIOV VF max rate limit support - Introduce TSAR manipulation firmware commands - Introduce E-switch QoS management - Add SRIOV VF max rate configuration support From Mark Bloch (7): mlx5e Tc support for FWD rule with counter - Don't unlock fte while still using it - Use fte status to decide on firmware command - Refactor find_flow_rule - Group similar rules under the same fte - Add multi dest support - Add option to add fwd rule with counter - mlx5e tc support for FWD rule with counter Mark here fixed two trivial issues with the flow steering core, and did some refactoring in the flow steering API to support adding mulit destination rules to the same hardware flow table entry at once. In the last two patches added the ability to populate a flow rule with a flow counter to the same flow entry. V2: Dropped some patches that added new structures without adding any usage of them. Added SRIOV VF max rate configuration support patch that introduces the usage of the TSAR infrastructure.

2016-10-30mlxsw: core: Zero payload buffers for couple of registersElad Raz3-4/+4
We recently discovered a bug in the firmware in which a field's length in one of the registers was incorrectly set. This caused the firmware to access garbage data that wasn't initialized by the driver and therefore emit error messages. While the bug is already fixed and the driver usually zeros the buffers passed to the firmware, there are a handful of cases where this isn't done. Zero the buffer in these cases and prevent similar bugs from recurring, as they tend to be hard to debug.

Currently when calling mlx5_add_flow_rule we accept only one flow destination, this commit allows to pass multiple destinations. This change forces us to change the return structure to a more flexible one. We introduce a flow handle (struct mlx5_flow_handle), it holds internally the number for rules created and holds an array where each cell points the to a flow rule. From the consumers (of mlx5_add_flow_rule) point of view this change is only cosmetic and requires only to change the type of the returned value they store. From the core point of view, we now need to use a loop when allocating and deleting rules (e.g given to us a flow handler).

The arbitration defines the QoS policy between the agents connected to the TSAR. The TSAR is a consist two main features: 1) BW Allocation between agents: The TSAR implements a defecit weighted round robin between the agents. Each agent attached to the TSAR is assigned with a weight and it is awarded transmission tokens according to this weight. 2) Rate limer per agent: Each agent attached to the TSAR is (optionally) assigned with a rate limit. TSAR will not allow scheduling for an agent exceeding its defined rate limit. In this patch we implement the API of manipulating the TSAR.

git://git.kernel.org/pub/scm/linux/kernel/git/jberg/mac80211-next Johannes Berg says: ==================== Among various cleanups and improvements, we have the following: * client FILS authentication support in mac80211 (Jouni) * AP/VLAN multicast improvements (Michael Braun) * config/advertising support for differing beacon intervals on multiple virtual interfaces (Purushottam Kushwaha, myself) * deprecate the old WDS mode for cfg80211-based drivers, the mode is hardly usable since it doesn't support any "modern" features like WPA encryption (2003), HT (2009) or VHT (2014), I'm not even sure WEP (introduced in 1997) could be done. ==================== Signed-off-by: David S.

2016-10-29enic: fix rq disableGovindarajulu Varadarajan1-9/+23
When MTU is changed from 9000 to 1500 while there is burst of inbound 9000 bytes packets, adaptor sometimes delivers 9000 bytes packets to 1500 bytes buffers. This causes memory corruption and sometimes crash. This is because of a race condition in adaptor between "RQ disable" clearing descriptor mini-cache and mini-cache valid bit being set by completion of descriptor fetch. This can result in stale RQ desc being cached and used when packets arrive. In this case, the stale descriptor have old MTU value. Solution is to write RQ->disable twice. The first write will stop any further desc fetches, allowing the second disable to clear the mini-cache valid bit without danger of a race. Also, the check for rq->running becoming 0 after writing rq->enable to 0 is not done properly. When incoming packets are flooding the interface, rq->running will pulse high for each dropped packet. Since the driver was waiting for 10us between each poll, it is possible to see rq->running = 1 1000 times in a row, even though it is not actually stuck running. This results in false failure of vnic_rq_disable(). Fix is to try more than 1000 time without delay between polls to ensure we do not miss when running goes low. In old adaptors rq->enable needs to be re-written to 0 when posted_index is reset in vnic_rq_clean() in order to keep rq->prefetch_index in sync.
