This patch silences an IRDA_ASSERT in irda_recvmsg_stream, as described in http://bugzilla.kernel.org/show_bug.cgi?id=7512 irda_disconnect_indication would set sk->sk_err to ECONNRESET, and a subsequent call to recvmsg would print an irritating kernel message and return -1. When a connected socket is closed by the peer, recvmsg should return 0 rather than an error. This patch fixes this.

This is an implementation of TCP Illinois invented by Shao Liu at University of Illinois. It is a another variant of Reno which adapts the alpha and beta parameters based on RTT. The basic idea is to increase window less rapidly as delay approaches the maximum. See the papers and talks to get a more complete description.

pppoe_flush_dev() kicks all sockets bound to a device that is going down. In doing so, locks must be taken in the right order consistently (sock lock, followed by the pppoe_hash_lock). However, the scan process is based on us holding the sock lock. So, when something is found in the scan we must release the lock we're holding and grab the sock lock. This patch fixes race conditions between this code and pppoe_release(), both of which perform similar functions but would naturally prefer to grab locks in opposing orders. Both code paths are now going after these locks in a consistent manner. pppoe_hash_lock protects the contents of the "pppox_sock" objects that reside inside the hash. Thus, NULL'ing out the pppoe_dev field should be done under the protection of this lock. Signed-off-by: NMichal Ostrowski <mostrows@earthlink.net> Signed-off-by: NDavid S.

below you find a patch that fixes a memory leak when a PPPoE socket is release()d after it has been connect()ed, but before the PPPIOCGCHAN ioctl ever has been called on it. This is somewhat of a security problem, too, since PPPoE sockets can be created by any user, so any user can easily allocate all the machine's RAM to non-swappable address space and thus DoS the system. Is there any specific reason for PPPoE sockets being available to any unprivileged process, BTW? After all, you need a packet socket for the discovery stage anyway, so it's unlikely that any unprivileged process will ever need to create a PPPoE socket, no? Allocating all session IDs for a known AC is a kind of DoS, too, after all - with Juniper ERXes, this is really easy, actually, since they don't ever assign session ids above 8000 ...

below you find a patch that (hopefully) fixes a race between an interface going down and a connect() to a peer on that interface. Before, connect() would determine that an interface is up, then the interface could go down and all entries referring to that interface in the item_hash_table would be marked as ZOMBIEs and their references to the device would be freed, and after that, connect() would put a new entry into the hash table referring to the device that meanwhile is down already - which also would cause unregister_netdevice() to wait until the socket has been release()d. This patch does not suffice if we are not allowed to accept connect()s referring to a device that we already acked a NETDEV_GOING_DOWN for (that is: all references are only guaranteed to be freed after NETDEV_DOWN has been acknowledged, not necessarily after the NETDEV_GOING_DOWN already). And if we are allowed to, we could avoid looking through the hash table upon NETDEV_GOING_DOWN completely and only do that once we get the NETDEV_DOWN ... mostrows: pppoe_flush_dev is called on NETDEV_GOING_DOWN and NETDEV_DOWN to deal with this "late connect" issue. Ideally one would hope to notify users at the "NETDEV_GOING_DOWN" phase (just to pretend to be nice). However, it is the NETDEV_DOWN scan that takes all the responsibility for ensuring nobody is hanging around at that time.

Add a packet socket option to allow the orig_dev index to be returned to userspace when passing traffic through a decapsulated device, such as the bonding driver.

Add IP(V6)_PMTUDISC_PROBE value for IP(V6)_MTU_DISCOVER. This option forces us not to fragment, but does not make use of the kernel path MTU discovery. That is, it allows for user-mode MTU probing (or, packetization-layer path MTU discovery). This is particularly useful for diagnostic utilities, like traceroute/tracepath.

Switch ingress queueing back to use ingress_lock. qdisc_lock_tree now locks both the ingress and egress qdiscs on the device. All changes to data that might be used on both ingress and egress needs to be protected by using qdisc_lock_tree instead of manually taking dev->queue_lock. Additionally the qdisc stats_lock needs to be initialized to ingress_lock for ingress qdiscs. Signed-off-by: NPatrick McHardy <kaber@trash.net> Signed-off-by: NDavid S. Miller <davem@davemloft.net>
