* | | sctp: fix the issue that flags are ignored when using kernel_connectXin Long2018-05-221-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Now sctp uses inet_dgram_connect as its proto_ops .connect, and the flags param can't be passed into its proto .connect where this flags is really needed. sctp works around it by getting flags from socket file in __sctp_connect. It works for connecting from userspace, as inherently the user sock has socket file and it passes f_flags as the flags param into the proto_ops .connect. However, the sock created by sock_create_kern doesn't have a socket file, and it passes the flags (like O_NONBLOCK) by using the flags param in kernel_connect, which calls proto_ops .connect later. So to fix it, this patch defines a new proto_ops .connect for sctp, sctp_inet_connect, which calls __sctp_connect() directly with this flags param. After this, the sctp's proto .connect can be removed. Note that sctp_inet_connect doesn't need to do some checks that are not needed for sctp, which makes thing better than with inet_dgram_connect.

* | bonding: send learning packets for vlans on slaveDebabrata Banerjee2018-05-111-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There was a regression at some point from the intended functionality of commit f60c3704e87d ("bonding: Fix alb mode to only use first level vlans.") Given the return value vlan_get_encap_level() we need to store the nest level of the bond device, and then compare the vlan's encap level to this. Without this, this check always fails and learning packets are never sent. In addition, this same commit caused a regression in the behavior of balance_alb, which requires learning packets be sent for all interfaces using the slave's mac in order to load balance properly. For vlan's that have not set a user mac, we can send after checking one bit. Otherwise we need send the set mac, albeit defeating rx load balancing for that vlan.

So keep occ_get callbacks registered only when all structs are initialized. The example flows, as it is in mlxsw: 1) driver load/asic probe: mlxsw_core -> mlxsw_sp_resources_register -> mlxsw_sp_kvdl_resources_register -> devlink_resource_register IDX mlxsw_spectrum -> mlxsw_sp_kvdl_init -> mlxsw_sp_kvdl_parts_init -> mlxsw_sp_kvdl_part_init -> devlink_resource_size_get IDX (to get the current setup size from devlink) -> devlink_resource_occ_get_register IDX (register current occupancy getter) 2) reload triggered by devlink command: -> mlxsw_devlink_core_bus_device_reload -> mlxsw_sp_fini -> mlxsw_sp_kvdl_fini -> devlink_resource_occ_get_unregister IDX (struct mlxsw_sp *mlxsw_sp is freed at this point, call to occ get which is using mlxsw_sp would cause use-after free) -> mlxsw_sp_init -> mlxsw_sp_kvdl_init -> mlxsw_sp_kvdl_parts_init -> mlxsw_sp_kvdl_part_init -> devlink_resource_size_get IDX (to get the current setup size from devlink) -> devlink_resource_occ_get_register IDX (register current occupancy getter) Fixes: d9f9b9a4d05f ("devlink: Add support for resource abstraction") Signed-off-by: Jiri Pirko <jiri@mellanox.com> Signed-off-by: David S.

Although if you look a bit closer, excluding the usual minor tweaks/fixes, there are really only two significant changes in this pull request: the addition of proper SELinux access controls for SCTP and the encapsulation of a lot of internal SELinux state. The SCTP changes are the result of a multi-month effort (maybe even a year or longer?) between the SELinux folks and the SCTP folks to add proper SELinux controls. A special thanks go to Richard for seeing this through and keeping the effort moving forward. The state encapsulation work is a bit of janitorial work that came out of some early work on SELinux namespacing. The question of namespacing is still an open one, but I believe there is some real value in the encapsulation work so we've split that out and are now sending that up to you" * tag 'selinux-pr-20180403' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/selinux: selinux: wrap AVC state selinux: wrap selinuxfs state selinux: fix handling of uninitialized selinux state in get_bools/classes selinux: Update SELinux SCTP documentation selinux: Fix ltp test connect-syscall failure selinux: rename the {is,set}_enforcing() functions selinux: wrap global selinux state selinux: fix typo in selinux_netlbl_sctp_sk_clone declaration selinux: Add SCTP support sctp: Add LSM hooks sctp: Add ip option support security: Add support for SCTP security hooks netlabel: If PF_INET6, check sk_buff ip header version
