The L2CAP layer\nwrongly uses always general bonding when creating new connections, but it\nshould not do this for SDP connections. In this case the authentication\nrequirement should be no bonding and the just-works model should be used,\nbut in case of non-SDP connection it is required to use general bonding.\n\nIf the new connection requires man-in-the-middle (MITM) protection, it\nalso first wrongly creates an unauthenticated link key and then later on\nrequests an upgrade to an authenticated link key to provide full MITM\nprotection. With Simple Pairing the link key generation is an expensive\noperation (compared to Bluetooth 2.0 and before) and doing this twice\nduring a connection setup causes a noticeable delay when establishing\na new connection. This should be avoided to not regress from the expected\nBluetooth 2.0 connection times. The authentication requirements are known\nup-front and so enforce them.\n\nTo fulfill these requirements the hci_connect() function has been extended\nwith an authentication requirement parameter that will be stored inside\nthe connection information and can be retrieved by userspace at any\ntime. This allows the correct IO capabilities exchange and results in\nthe expected behavior.\n\nSigned-off-by: Marcel Holtmann \u003cmarcel@holtmann.org\u003e\n" }, { "commit": "e1d7bf14999469b16e86889ac71c94a9d0d2f5f4", "tree": "32d56c2faac08ac02730a46498183e7222744705", "parents": [ "e228c1b51ef572843827630e643a682ef492b933", "291c54ff764d12ecc9a916cb478a0bbb45c5990e" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Mon Sep 08 15:47:21 2008 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Mon Sep 08 15:47:21 2008 -0700" }, "message": "Merge branch \u0027sched-fixes-for-linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip\n\n* \u0027sched-fixes-for-linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip:\n sched: arch_reinit_sched_domains() must destroy domains to force rebuild\n sched, cpuset: rework sched domains and CPU hotplug handling (v4)\n" }, { "commit": "bcbc713470283bc82d043fd23b02e41a9eb8dee5", "tree": "2cd88a1b83dad55dc9e489f151114c0717015ac5", "parents": [ "b364e2f5262e972e731a576dfc6ede0689a6c19e", "8d4698f7a54a492a1b96c505b30fe750ae3e61d5" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Mon Sep 08 15:43:44 2008 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Mon Sep 08 15:43:44 2008 -0700" }, "message": "Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-2.6\n\n* git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-2.6:\n bridge: don\u0027t allow setting hello time to zero\n netns : fix kernel panic in timewait socket destruction\n pkt_sched: Fix qdisc state in net_tx_action()\n netfilter: nf_conntrack_irc: make sure string is terminated before calling simple_strtoul\n netfilter: nf_conntrack_gre: nf_ct_gre_keymap_flush() fixlet\n netfilter: nf_conntrack_gre: more locking around keymap list\n netfilter: nf_conntrack_sip: de-static helper pointers\n" }, { "commit": "d315492b1a6ba29da0fa2860759505ae1b2db857", "tree": "1019a3c34af19939733e6d1e7d3163c73c73eb69", "parents": [ "e8a83e10d7dfe5d0841062780769b30f65417e15" ], "author": { "name": "Daniel Lezcano", "email": "dlezcano@fr.ibm.com", "time": "Mon Sep 08 13:17:27 2008 -0700" }, "committer": { "name": "David S.

The timewait sockets life cycle is not tied with\nthe network namespace, that means the timewait sockets stay alive while\nthe network namespace dies. The timewait sockets are for avoiding to\nreceive a duplicate packet from the network, if the network namespace is\nfreed, the network stack is removed, so no chance to receive any packets\nfrom the outside world. Furthermore, having a pending destruction timer\non these sockets with a network namespace freed is not safe and will lead\nto an oops if the timer callback which try to access data belonging to \nthe namespace like for example in:\n\tinet_twdr_do_twkill_work\n\t\t-\u003e NET_INC_STATS_BH(twsk_net(tw), LINUX_MIB_TIMEWAITED);\n\nPurging the timewait sockets at the network namespace destruction will:\n 1) speed up memory freeing for the namespace\n 2) fix kernel panic on asynchronous timewait destruction\n\nSigned-off-by: Daniel Lezcano \u003cdlezcano@fr.ibm.com\u003e\nAcked-by: Denis V.
