xfrm Fix potential error pointer dereference in xfrm_bundle_create.

2018-05-31T07:53:04+00:00

We may derference an invalid pointer in the error path of xfrm_bundle_create(). Fix this by returning this error pointer directly instead of assigning it to xdst0. Fixes: 45b018beddb6 ("ipsec: Create and use new helpers for dst child access.") Signed-off-by: Steffen Klassert

xfrm: Fix warning in xfrm6_tunnel_net_exit.

2018-04-16T05:50:09+00:00

We need to make sure that all states are really deleted before we check that the state lists are empty. Otherwise we trigger a warning.

Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net

2018-04-01T23:49:34+00:00

Minor conflicts in drivers/net/ethernet/mellanox/mlx5/core/en_rep.c, we had some overlapping changes: 1) In 'net' MLX5E_PARAMS_LOG_{SQ,RQ}_SIZE --> MLX5E_REP_PARAMS_LOG_{SQ,RQ}_SIZE 2) In 'net-next' params->log_rq_size is renamed to be params->log_rq_mtu_frames. 3) In 'net-next' params->hard_mtu is added.

xfrm: Register xfrm_dev_notifier in appropriate place

2018-03-30T14:59:23+00:00

Currently, driver registers it from pernet_operations::init method, and this breaks modularity, because initialization of net namespace and netdevice notifiers are orthogonal actions. We don't have per-namespace netdevice notifiers; all of them are global for all devices in all namespaces. Signed-off-by: Kirill Tkhai Signed-off-by: David S. Miller

net: Drop pernet_operations::async

2018-03-27T17:18:09+00:00

Synchronous pernet_operations are not allowed anymore. All are asynchronous. So, drop the structure member. Signed-off-by: Kirill Tkhai Signed-off-by: David S. Miller

net: Use octal not symbolic permissions

2018-03-26T16:07:48+00:00

Prefer the direct use of octal for permissions. Done with checkpatch -f --types=SYMBOLIC_PERMS --fix-inplace and some typing. Miscellanea: o Whitespace neatening around these conversions. Signed-off-by: Joe Perches Signed-off-by: David S. Miller

Fun set of conflict resolutions here... For the mac80211 stuff, these were fortunately just parallel adds. Trivially resolved. In drivers/net/phy/phy.c we had a bug fix in 'net' that moved the function phy_disable_interrupts() earlier in the file, whilst in 'net-next' the phy_error() call from this function was removed. In net/ipv4/xfrm4_policy.c, David Ahern's changes to remove the 'rt_table_id' member of rtable collided with a bug fix in 'net' that added a new struct member "rt_mtu_locked" which needs to be copied over here. The mlxsw driver conflict consisted of net-next separating the span code and definitions into separate files, whilst a 'net' bug fix made some changes to that moved code. The mlx5 infiniband conflict resolution was quite non-trivial, the RDMA tree's merge commit was used as a guide here, and here are their notes: ==================== Due to bug fixes found by the syzkaller bot and taken into the for-rc branch after development for the 4.17 merge window had already started being taken into the for-next branch, there were fairly non-trivial merge issues that would need to be resolved between the for-rc branch and the for-next branch. This merge resolves those conflicts and provides a unified base upon which ongoing development for 4.17 can be based. Conflicts: drivers/infiniband/hw/mlx5/main.c - Commit 42cea83f9524 (IB/mlx5: Fix cleanup order on unload) added to for-rc and commit b5ca15ad7e61 (IB/mlx5: Add proper representors support) add as part of the devel cycle both needed to modify the init/de-init functions used by mlx5. To support the new representors, the new functions added by the cleanup patch needed to be made non-static, and the init/de-init list added by the representors patch needed to be modified to match the init/de-init list changes made by the cleanup patch. Updates: drivers/infiniband/hw/mlx5/mlx5_ib.h - Update function prototypes added by representors patch to reflect new function names as changed by cleanup patch drivers/infiniband/hw/mlx5/ib_rep.c - Update init/de-init stage list to match new order from cleanup patch ==================== Signed-off-by: David S.

xfrm: Fix transport mode skb control buffer usage.

2018-03-23T06:56:04+00:00

A recent commit introduced a new struct xfrm_trans_cb that is used with the sk_buff control buffer. Unfortunately it placed the structure in front of the control buffer and overlooked that the IPv4/IPv6 control buffer is still needed for some layer 4 protocols. As a result the IPv4/IPv6 control buffer is overwritten with this structure. Fix this by setting a apropriate header in front of the structure.

xfrm: fix rcu_read_unlock usage in xfrm_local_error

2018-03-16T07:26:02+00:00

In the xfrm_local_error, rcu_read_unlock should be called when afinfo is not NULL. because xfrm_state_get_afinfo calls rcu_read_unlock if afinfo is NULL. Fixes: af5d27c4e12b ("xfrm: remove xfrm_state_put_afinfo") Signed-off-by: Taehee Yoo Signed-off-by: Steffen Klassert
