2015-12-15mISDN: fix a loop countDan Carpenter
There are two issue here. 1) cnt starts as maxloop + 1 so all these loops iterate one more time than intended. 2) At the end of the loop we test for "if (maxloop && !cnt)" but for the first two loops, we end with cnt equal to -1. Changing this to a pre-op means we end with cnt set to 0.

2015-12-15Merge branch 'mlxsw-bridge-vlan-offloading'David S. Miller
Ido Schimmel says: ==================== This patchset introduces support for the offloading of 802.1D bridges between VLAN devices. These can either be VLAN devices configured on top of the physical ports or on top of LAG devices. Patches 1-2 deal with the necessary infrastructure changes needed in order to enable the above. The main change is that switchdev drivers can now know the device from which the switchdev op originated from. Patches 3-10 lay the groundwork for 802.1D bridges support in the mlxsw driver, with patch 4 doing most of the heavy lifting. Patch 11 finally offloads these bridges to hardware by listening to the notifications sent when the VLAN device joins or leaves a bridge. It is very similar to the already existing 802.1Q bridge we support. Patches 12-14 add minor modifications to allow one to bridge a VLAN device configured on top of LAG. ==================== Signed-off-by: Jiri Pirko <jiri@mellanox.com> Signed-off-by: David S.

2015-12-15mlxsw: spectrum: Add support for VLAN devices on top of LAGIdo Schimmel
When creating a VLAN device on top of LAG, we are basically creating a vPort on top of each of the port netdevs member in the LAG. Therefore, these vPorts should inherit both the LAG status and LAG ID from the underlying port netdevs. In addition, when the VLAN device joins or leaves a bridge each of the underlying vPorts should know about it and act accordingly. This is achieved by propagating the VLAN event down to the lower devices. Signed-off-by: Ido Schimmel <idosch@mellanox.com> Signed-off-by: Jiri Pirko <jiri@mellanox.com> Signed-off-by: David S.

2015-12-15mlxsw: spectrum: Add support for VLAN devices bridgingIdo Schimmel
All the member VLAN devices in a bridge need to share the same vFID. To achieve that, expand the vFID struct to include the associated bridge device (or lack of) and allow one to lookup a vFID based on a bridge device. When joining a bridge, lookup the relevant vFID or create one if none exists. Next, make the VLAN device use the vFID. Leaving a bridge can either occur because a user removed the VLAN device from a bridge or because the VLAN device was deleted by the user. In the latter case the bridge's teardown sequence is invoked after the hardware vPort is already gone. Therefore, when unlinking the VLAN device from the real device, check if the associated vPort is bridged and act accordingly. The bridge's notification will be ignored in this case. Note that bridging a VLAN interface with an ordinary port netdev is currently not supported, but not forbidden. This will be addressed in a follow-up patchset.

2015-12-15mlxsw: spectrum: Handle VLAN devices linking / unlinkingIdo Schimmel
When a VLAN interface is configured on top of a physical port we should associate the VLAN device with the matching vPort. Likewise, when it's removed, we should revert back to the underlying port netdev. While not a must, this is consistent with port netdevs and also provides a more accurate error printing via netdev_err() and friends.

2015-12-15mlxsw: spectrum: Adjust FDB notifications for VLAN devicesIdo Schimmel
FDB notifications contain the FID and port (or LAG ID) on which the MAC was learned. In the case of the 802.1Q bridge one can easily derive the matching VID - as FID equals VID - and generate the appropriate notification for the software bridge. With VLAN devices this is no longer the case, as these are associated with a vFID. Solve that by converting the FID to a vFID and lookup the matching VLAN device. From that derive the VID and whether learning (and learning sync) should occur. Signed-off-by: Ido Schimmel <idosch@mellanox.com> Signed-off-by: Jiri Pirko <jiri@mellanox.com> Signed-off-by: David S.

However, since we are going to add support for bridges between VLAN interfaces (mapped to vFIDs) we need to add one more flood table.

2015-12-15mlxsw: spectrum: Split vFID range in twoIdo Schimmel
Up until now we used a 1:1 mapping - based on VID - to map a VLAN interface to a vFID. However, a different scheme is needed in order to support bridges between VLAN interfaces, as all the member interfaces - which can have different VIDs - need to share the same vFID. Solve that by splitting the vFID range in two: 1. Non-bridged VLAN interfaces 2. Bridged VLAN interfaces When a VLAN interface is created, assign it the next available vFID in the first range, unless one already exists for that VID or number of vFIDs in the range was exceeded. When interface is removed, free the vFID, unless other interfaces are mapped to it. To accomplish the above: 1. Store the VID to vFID mapping in a new struct (mlxsw_sp_vfid), which has a global context and holds a reference count. 2. Create a vPort (dummy in case of bridge SELF invocation) on top of of the physical port and hold a reference to the associated vFID. vfid vfid +-------------+ +-------------+ | vfid | | vfid | | vid +---> ... | vid | | nr_vports | | nr_vports | +------+------+ +------+------+ | +-----------------------+-------+ | | vport vport +-------------+ +-------------+ | ... | | ... | | *vfid +---> ... | *vfid +---> ... | ... | | ... | +------+------+ +------+------+ | | port port +-------------+ +-------------+ | ... | | ... | | vports_list | | vports_list | | ... | | ... | +-------------+ +-------------+ swXpY swXpZ Next patches in the series will add the missing infrastructure for the second range and transfer vPorts between the two ranges according to the received notifications.

2015-12-15mlxsw: spectrum: Allocate active VLANs only for port netdevsIdo Schimmel
When adding support for bridges between VLAN interfaces, we'll introduce a new entity called a vPort, which is a represntation of the VLAN interface in the hardware. The main difference between a vPort and a physical port is that several FIDs can be bound to the latter, whereas only one (called a vFID) can be bound to the first. Therefore, it makes sense to use the same struct to represent the two, but to only allocate the 'active_vlans' bitmap in case of a physical port.

2015-12-15switchdev: Pass original device to port netdev driverIdo Schimmel
switchdev drivers need to know the netdev on which the switchdev op was invoked. For example, the STP state of a VLAN interface configured on top of a port can change while being member in a bridge. In this case, the underlying driver should only change the STP state of that particular VLAN and not of all the VLANs configured on the port. However, current switchdev infrastructure only passes the port netdev down to the driver. Solve that by passing the original device down to the driver as part of the required switchdev object / attribute. This doesn't entail any change in current switchdev drivers. It simply enables those supporting stacked devices to know the originating device and act accordingly.

Alex Duyck changes e1000_up() to void since it always returned 0, also by making it void, we can drop some code since we no longer have to worry about non-zero return values. Aaron Sierra removes GS40G specific defines and functions since the i210 internal PHY can be accessed with the access functions shared by 82580, i350 and i354 devices. Also removes the code to add the PHY address into the PCDL register address, since there is no real reason to do so. Joe updates the cable length function reports all four pairs true min, max and average cable length for i210. Also updated ethtool to use enum-based labels instead of hard coded values. Benjamin Poirier cleans up code that is never reachable since MSI-X interrupts are not shared in e1000e. Also removes the ICR read in the other interrupt handler, since the information is not needed and IMS is configured such that the only link status change can trigger the other interrupt handler. Fixed in MSI-X mode, there is no handler for the LSC interrupt so there is no point in writing that to ICS now that we always assume other interrupts are caused by LSC. ==================== Signed-off-by: David S.

2015-12-14net: fix IP early demux racesEric Dumazet
David Wilder reported crashes caused by dst reuse. <quote David> I am seeing a crash on a distro V4.2.3 kernel caused by a double release of a dst_entry. In ipv4_dst_destroy() the call to list_empty() finds a poisoned next pointer, indicating the dst_entry has already been removed from the list and freed. The crash occurs 18 to 24 hours into a run of a network stress exerciser. </quote> Thanks to his detailed report and analysis, we were able to understand the core issue. IP early demux can associate a dst to skb, after a lookup in TCP/UDP sockets. When socket cache is not properly set, we want to store into sk->sk_dst_cache the dst for future IP early demux lookups, by acquiring a stable refcount on the dst. Problem is this acquisition is simply using an atomic_inc(), which works well, unless the dst was queued for destruction from dst_release() noticing dst refcount went to zero, if DST_NOCACHE was set on dst. We need to make sure current refcount is not zero before incrementing it, or risk double free as David reported. This patch, being a stable candidate, adds two new helpers, and use them only from IP early demux problematic paths. It might be possible to merge in net-next skb_dst_force() and skb_dst_force_safe(), but I prefer having the smallest patch for stable kernels : Maybe some skb_dst_force() callers do not expect skb->dst can suddenly be cleared.

2015-12-14e1000e: Fix msi-x interrupt automaskBenjamin Poirier
Since the introduction of 82574 support in e1000e, the driver has worked on the assumption that msi-x interrupt generation is automatically disabled after each irq. As it turns out, this is not the case. Currently, rx interrupts can fire multiple times before and during napi processing. This can be a problem for users because frames that arrive in a certain window (after adapter->clean_rx() but before napi_complete_done() has cleared NAPI_STATE_SCHED) generate an interrupt which does not lead to napi_schedule(). These frames sit in the rx queue until another frame arrives (a tcp retransmit for example). While the EIAC and CTRL_EXT registers are properly configured for irq automask, the modification of IAM in e1000_configure_msix() is what prevents automask from working as intended. This patch removes that erroneous write and fixes interrupt rearming for tx interrupts. It also clears IAME from CTRL_EXT. This is not strictly necessary for operation of the driver but it is to avoid disruption from potential programs that access the registers directly, like `ethregs -c`.

2015-12-15drm: Don't overwrite UNVERFIED mode status to OKVille Syrjälä
The way the mode probing works is this: 1. All modes currently on the mode list are marked as UNVERIFIED 2. New modes are on the probed_modes list (they start with status OK) 3. Modes are moved from the probed_modes list to the actual mode list. If a mode already on the mode list is deemed to match one of the probed modes, the duplicate is dropped and the mode status updated to OK. After this the probed_modes list will be empty. 4. All modes on the mode list are verified to not violate any constraints. Any that do are marked as such. 5. Any mode left with a non-OK status is pruned from the list, with an appropriate debug message. What all this means is that any mode on the original list that didn't have a duplicate on the probed_modes list, should be left with status UNVERFIED (or previously could have been left with some other status, but never OK). I broke that in commit 05acaec334fc ("drm: Reorganize probed mode validation") by always assigning something to the mode->status during the validation step. So any mode from the old list that still passed the validation would be left on the list with status OK in the end. Fix this by not doing the basic mode validation unless the mode already has status OK (meaning it came from the probed_modes list, or at least a duplicate of it was on that list). This way we will correctly prune away any mode from the old mode list that didn't appear on the probed_modes list.
