2015-09-30net: Add support for filtering neigh dump by master deviceDavid Ahern2-1/+32
Add support for filtering neighbor dumps by master device by adding the NDA_MASTER attribute to the dump request. A new netlink flag, NLM_F_DUMP_FILTERED, is added to indicate the kernel supports the request and output is filtered as requested.

2015-09-30Merge branch 'switchdev-callback'David S. Miller6-201/+186
Vivien Didelot says: ==================== net: switchdev: use specific switchdev_obj_* This patchset changes switchdev add, del, dump operations from this: int (*switchdev_port_obj_add)(struct net_device *dev, struct switchdev_obj *obj, struct switchdev_trans *trans); int (*switchdev_port_obj_del)(struct net_device *dev, struct switchdev_obj *obj); int (*switchdev_port_obj_dump)(struct net_device *dev, struct switchdev_obj *obj); to something similar to the notifier_call callback of a notifier_block: int (*switchdev_port_obj_add)(struct net_device *dev, enum switchdev_obj_id id, const void *obj, struct switchdev_trans *trans); int (*switchdev_port_obj_del)(struct net_device *dev, enum switchdev_obj_id id, const void *obj); int (*switchdev_port_obj_dump)(struct net_device *dev, enum switchdev_obj_id id, void *obj, int (*cb)(void *obj)); This allows the caller to pass and expect back a specific switchdev_obj_* structure (e.g. switchdev_obj_fdb) instead of the generic switchdev_obj one. This will simplify pushing the callback function down to the drivers. The first 3 patches get rid of the dev parameter of the dump callback, since it is not always neeeded (e.g. vlan_dump) and some drivers (such as DSA drivers) may not have easy access to it. Patches 4 and 5 implement the change in the switchdev operations and its users. Patch 6 extracts the inner switchdev_obj_* structures from switchdev_obj and removes this last one. v2: fix error spotted by kbuild (extra ';' inline switchdev_port_obj_dump). ==================== Signed-off-by: David S.

2015-09-30net/mlx4: Handle return codes in mlx4_qp_attach_commonRobb Manes1-3/+4
Both new_steering_entry() and existing_steering_entry() return values based on their success or failure, but currently they fall through silently. This can make troubleshooting difficult, as we were unable to tell which one of these two functions returned errors or specifically what code was returned. This patch remedies that situation by passing the return codes to err, which is returned by mlx4_qp_attach_common() itself. This also addresses a leak in the call to mlx4_bitmap_free() as well.

2015-09-30Merge branch 'L3_master_device'David S. Miller21-276/+356
David Ahern says: ==================== net: L3 master device The VRF device is essentially a Layer 3 master device used to associate netdevices with a specific routing table and to influence FIB lookups via 'ip rules' and controlling the oif/iif used for the lookup. This series generalizes the VRF into L3 master device, l3mdev. Similar to switchdev it has a Kconfig option and separate set of operations in net_device allowing it to be completely compiled out if not wanted. The l3mdev methods rely on the 'master' aspect and use of netdev_master_upper_dev_get_rcu to retrieve the master device from a given netdevice if it is enslaved to an L3_MASTER. The VRF device is converted to use the l3mdev operations. At the end the vrf_ptr is no longer and removed, as are all direct references to VRF. The end result is a much simpler implementation for VRF. Thanks to Nikolay for suggestions (eg., use of the master linkage which is the key to making this work) and to Roopa, Andy and Shrijeet for early reviews. v3 - added license header to l3mdev.c - export symbols in l3mdev.c for use with GPL modules - removed netdevice header from l3mdev.h (not needed) and fixed typo in comment v2 - rebased to top of net-next - addressed Niks comments (checking master, removing extra lines, and flipping the order of patches 1 and 2) ==================== Signed-off-by: David S.

While auditing TCP stack for upcoming 'lockless' listener changes, I found I had to change fastopen_init_queue() to properly init the object before publishing it. Otherwise an other cpu could try to lock the spinlock before it gets properly initialized. Instead of adding appropriate barriers, just remove dynamic memory allocations : - Structure is 28 bytes on 64bit arches. Using additional 8 bytes for holding a pointer seems overkill. - Two listeners can share same cache line and performance would suffer. If we really want to save few bytes, we would instead dynamically allocate whole struct request_sock_queue in the future. Signed-off-by: Eric Dumazet <edumazet@google.com> Signed-off-by: David S.
