This patch moves the non-proc SNMP code into addrconf.c and reuses IPv4 SNMP code where applicable. As a result we can skip proc.o if /proc is disabled. Note that I've made a number of functions static since they're only used by addrconf.c for now. If they ever get used elsewhere we can always remove the static. Signed-off-by:

This patch moves the SNMP code shared between IPv4/IPv6 from proc.c into net/ipv4/af_inet.c. This makes sense because these functions aren't specific to /proc. As a result we can again skip proc.o if /proc is disabled. Signed-off-by:

This patch makes two enhancements to msg_set_bits(): 1) It now ignores any bits of the new field value that are not covered by the mask being used. (Previously, if the new value exceeded the size of the mask the extra bits could corrupt other fields in the message header word being updated.) 2) The code has been optimized to minimize the number of run-time endianness conversion operations by leveraging the fact that the mask (and, in some cases, the value as well) is constant and the necessary conversion can be performed by the compiler.

Now that Patrick has added the code to deal with GSO in netfilter, we no longer need the crutch that computes partial checksums just before transmission. This patch turns this into a warning again. If this goes OK, we can then turn it into a BUG_ON and remove the gso_send_check cruft. Signed-off-by:

Do some simple changes to make congestion control API faster/cleaner. * use ktime_t rather than timeval * merge rtt sampling into existing ack callback this means one indirect call versus two per ack. * use flags bits to store options/settings Signed-off-by:

This version more closely matches the paper, and fixes several math errors. The biggest difference is that it updates alpha/beta once per RTT Signed-off-by:

This patch creates the core cfg80211 code along with some sysfs bits. This is a stripped down version to allow mac80211 to function, but doesn't include any configuration yet except for creating and removing virtual interfaces. This patch includes the nl80211 header file but it only contains the interface types which the cfg80211 interface for creating virtual interfaces relies on. Signed-off-by:

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. Signed-off-by:

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. Signed-off-by:

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:

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 ... Signed-off-by:

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. Signed-off-by:
