2015-03-24Bluetooth: Filter list of supported commands/events for untrusted usersMarcel Holtmann
When the user of the management interface is not trusted, then it only has access to a limited set of commands and events. When providing the list of supported commands and events take the trusted vs untrusted status of the user into account and return different lists. This way the untrusted user knows exactly which commands it can execute and which events it can receive. So no guesswork needed.

Eric Dumazet says: ==================== tcp: listener refactor part 16 A CONFIG_PROVE_RCU=y build revealed an RCU splat I had to fix. I added const qualifiers to various md5 methods, as I expect to call them on behalf of request sock traffic even if the listener socket is not locked. This seems ok, but adding const makes the contract clearer. Note a good reduction of code size thanks to request/establish sockets convergence. ==================== Signed-off-by: David S.

While timer handler effectively runs a rcu read locked section, there is no explicit rcu_read_lock()/rcu_read_unlock() annotations and lockdep can be confused here : net/ipv4/tcp_ipv4.c-906- /* caller either holds rcu_read_lock() or socket lock */ net/ipv4/tcp_ipv4.c:907: md5sig = rcu_dereference_check(tp->md5sig_info, net/ipv4/tcp_ipv4.c-908- sock_owned_by_user(sk) || net/ipv4/tcp_ipv4.c-909- lockdep_is_held(&sk->sk_lock.slock)); Let's explicitely acquire rcu_read_lock() in tcp_make_synack() Before commit fa76ce7328b ("inet: get rid of central tcp/dccp listener timer"), we were holding listener lock so lockdep was happy.

If vlan offloading takes place then vlan header is removed from frame and its contents, both vlan_tci and vlan_proto, is available to user space via TPACKET interface. However, only vlan_tci can be used in BPF filters. This commit introduces a new BPF extension. It makes possible to load the value of vlan_proto (vlan TPID) to register A.

We occasionally see in procedure mlx4_GEN_EQE that the driver tries to grab an uninitialized mutex. This can occur in only one of two ways: 1. We are trying to generate an async event on an uninitialized slave. 2. We are trying to generate an async event on an illegal slave number ( < 0 or > persist->num_vfs) or an inactive slave. To deal with #1: move the mutex initialization from specific slave init sequence in procedure mlx_master_do_cmd to mlx4_multi_func_init() (so that the mutex is always initialized for all slaves). To deal with #2: check in procedure mlx4_GEN_EQE that the slave number provided is in the proper range and that the slave is active.

Netdevice registration should be performed a the end of the driver initialization flow. If we don't do that, after calling register_netdevice, device callbacks may be issued by higher layers of the stack before final configuration of the device is done. For example (VXLAN configuration race), mlx4_SET_PORT_VXLAN was issued after the register_netdev command. System network scripts may configure the interface (UP) right after the registration, which also attach unicast VXLAN steering rule, before mlx4_SET_PORT_VXLAN was called, causing the firmware to fail the rule attachment.
