2016-10-21net: remove MTU limits on a few ether_setup callersJarod Wilson
These few drivers call ether_setup(), but have no ndo_change_mtu, and thus were overlooked for changes to MTU range checking behavior. They previously had no range checks, so for feature-parity, set their min_mtu to 0 and max_mtu to ETH_MAX_MTU (65535), instead of the 68 and 1500 inherited from the ether_setup() changes. Fine-tuning can come after we get back to full feature-parity here.

2016-10-13net: deprecate eth_change_mtu, remove usageJarod Wilson
With centralized MTU checking, there's nothing productive done by eth_change_mtu that isn't already done in dev_set_mtu, so mark it as deprecated and remove all usage of it in the kernel. All callers have been audited for calls to alloc_etherdev* or ether_setup directly, which means they all have a valid dev->min_mtu and dev->max_mtu. Now eth_change_mtu prints out a netdev_warn about being deprecated, for the benefit of out-of-tree drivers that might be utilizing it. Of note, dvb_net.c actually had dev->mtu = 4096, while using eth_change_mtu, meaning that if you ever tried changing it's mtu, you couldn't set it above 1500 anymore. It's now getting dev->max_mtu also set to 4096 to remedy that. v2: fix up lantiq_etop, missed breakage due to drive not compiling on x86 CC: netdev@vger.kernel.org Signed-off-by: Jarod Wilson <jarod@redhat.com> Signed-off-by: David S.

2015-12-11Bluetooth: Do not filter multicast addresses by defaultDanny Schweizer
A Linux PC is connected with another device over Bluetooth PAN using a BNEP interface. Whenever a packet is tried to be sent over the BNEP interface, the function "bnep_net_xmit()" in "net/bluetooth/bnep/netdev.c" is called. This function calls "bnep_net_mc_filter()", which checks (if the destination address is multicast) if the address is set in a certain multicast filter (&s->mc_filter). If it is not, then it is not sent out. This filter is only changed in two other functions, found in net/bluetooth/bnep/core.c": in "bnep_ctrl_set_mc_filter()", which is only called if a message of type "BNEP_FILTER_MULTI_ADDR_SET" is received. Otherwise, it is set in "bnep_add_connection()", where it is set to a default value which only adds the broadcast address to the filter: set_bit(bnep_mc_hash(dev->broadcast), (ulong *) &s->mc_filter); To sum up, if the BNEP interface does not receive any message of type "BNEP_FILTER_MULTI_ADDR_SET", it will not send out any messages with multicast destination addresses except for broadcast. However, in the BNEP specification (page 27 in http://grouper.ieee.org/groups/802/15/Bluetooth/BNEP.pdf), it is said that per default, all multicast addresses should not be filtered, i.e. the BNEP interface should be able to send packets with any multicast destination address. It seems that the default case is wrong: the multicast filter should not block almost all multicast addresses, but should not filter out any. This leads to the problem that e.g. Neighbor Solicitation messages sent with Bluetooth PAN over the BNEP interface to a multicast destination address other than broadcast are blocked and not sent out. Therefore, in the default case, we set the mc_filter to ~0LL to not filter out any multicast addresses.

2015-04-03Bluetooth: bnep: Handle BNEP connection setup requestGrzegorz Kolodziejczyk
With this patch kernel will be able to handle setup request. This is needed if we would like to handle control mesages with extension headers. User space will be only resposible for reading setup data and checking if scenario is conformance to specification (dst and src device bnep role). In case of new user space, setup data must be leaved(peek msg) on queue. New bnep session will be responsible for handling this data.

2015-04-03Bluetooth: bnep: Add support for get bnep features via ioctlGrzegorz Kolodziejczyk
This is needed if user space wants to know supported bnep features by kernel, e.g. if kernel supports sending response to bnep setup control message. By now there is no possibility to know supported features by kernel in case of bnep. Ioctls allows only to add connection, delete connection, get connection list, get connection info. Adding connection if it's possible (establishing network device connection) is equivalent to starting bnep session. Bnep session handles data queue of transmit, receive messages over bnep channel. It means that if we add connection the received/transmitted data will be parsed immediately. In case of get bnep features we want to know before session start, if we should leave setup data on socket queue and let kernel to handle with it, or in case of no setup handling support, if we should pull this message and handle setup response within user space.

2011-08-11Bluetooth: bnep: Fix deadlock in session deletionPeter Hurley
Commit f4d7cd4a4c introduced the usage of kthread API. kthread_stop is a blocking function which returns only when the thread exits. In this case, the thread can't exit because it's waiting for the write lock, which is being held by bnep_del_connection() which is waiting for the thread to exit -- deadlock. Use atomic_t/wake_up_process instead to signal to the thread to exit.
