| * [Bluetooth] Convert RFCOMM to use kthread APIMarcel Holtmann2007-10-22
| | | | | | | | | | | | | | | | | | This patch does the full kthread conversion for the RFCOMM protocol. It makes the code slightly simpler and more maintainable. Based on a patch from Christoph Hellwig <hch@lst.de> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
| * [Bluetooth] Add support for handling simple eSCO linksMarcel Holtmann2007-10-22
| | | | | | | | | | | | | | | | | | | | With the Bluetooth 1.2 specification the Extended SCO feature for better audio connections was introduced. So far the Bluetooth core wasn't able to handle any eSCO connections correctly. This patch adds simple eSCO support while keeping backward compatibility with older devices.

| * [Bluetooth] Retrieve L2CAP features mask on connection setupMarcel Holtmann2007-10-22
| | | | | | | | | | | | | | | | | | | | The Bluetooth 1.2 specification introduced a specific features mask value to interoperate with newer versions of the specification. So far this piece of information was never needed, but future extensions will rely on it. This patch adds a generic way to retrieve this information only once per connection setup.

| * [Bluetooth] Switch from OGF+OCF to using only opcodesMarcel Holtmann2007-10-22
| | | | | | | | | | | | | | | | | | | | | | | | The Bluetooth HCI commands are divided into logical OGF groups for easier identification of their purposes. While this still makes sense for the written specification, its makes the code only more complex and harder to read. So instead of using separate OGF and OCF values to identify the commands, use a common 16-bit opcode that combines both values. As a side effect this also reduces the complexity of OGF and OCF calculations during command header parsing. Signed-off-by: Marcel Holtmann <marcel@holtmann.org>

| * [NET]: Fix possible dev_deactivate race conditionHerbert Xu2007-10-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The function dev_deactivate is supposed to only return when all outstanding transmissions have completed. Unfortunately it is possible for store operations in the driver's transmit function to only become visible after dev_deactivate returns. This patch fixes this by taking the queue lock after we see the end of the queue run. This ensures that all effects of any previous transmit calls are visible. If however we detect that there is another queue run occuring, then we'll warn about it because this should never happen as we have pointed dev->qdisc to noop_qdisc within the same queue lock earlier in the functino.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There is a justifying patch for Stephen's patches. Stephen's patches disallows using a port range of one single port and brakes the meaning of the 'remaining' variable, in some places it has different meaning. My patch gives back the sense of 'remaining' variable. It should mean how many ports are remaining and nothing else. Also my patch allows using a single port. I sure we must be able to use mentioned port range, this does not restricted by documentation and does not brake current behavior. usefull links: Patches posted by Stephen Hemminger http://marc.info/?l=linux-netdev&m=119206106218187&w=2 http://marc.info/?l=linux-netdev&m=119206109918235&w=2 Andrew Morton's comment http://marc.info/?l=linux-kernel&m=119248225007737&w=2 1.

We already account for a similar problem with some Apple Airport devices, but at least one device is known to send more than a single extra byte. The device in question is the Draytek Vigor2900: http://www.draytek.com.au/products/Vigor2900.php The junk in question looks like an IE that runs off the end of the frame. This cause us to return ParseFailed. Since the frame in question is an association response, this causes us to fail to associate with this AP. The return code from ieee802_11_parse_elems is superfluous. All callers still check for the presence of the specific IEs that interest them anyway. So, remove the return code so the parse never "fails". Acked-by: Michael Wu <flamingice@sourmilk.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>

* | | pid namespaces: changes to show virtual ids to userPavel Emelyanov2007-10-19

Make all (I hope) the places where the pid is shown to or get from user operate on the virtual pids. The idea is: - all in-kernel data structures must store either struct pid itself or the pid's global nr, obtained with pid_nr() call; - when seeking the task from kernel code with the stored id one should use find_task_by_pid() call that works with global pids; - when showing pid's numerical value to the user the virtual one should be used, but however when one shows task's pid outside this task's namespace the global one is to be used; - when getting the pid from userspace one need to consider this as the virtual one and use appropriate task/pid-searching functions.

* | | Make access to task's nsproxy lighterPavel Emelyanov2007-10-19
|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When someone wants to deal with some other taks's namespaces it has to lock the task and then to get the desired namespace if the one exists. This is slow on read-only paths and may be impossible in some cases. E.g. Oleg recently noticed a race between unshare() and the (sent for review in cgroups) pid namespaces - when the task notifies the parent it has to know the parent's namespace, but taking the task_lock() is impossible there - the code is under write locked tasklist lock. On the other hand switching the namespace on task (daemonize) and releasing the namespace (after the last task exit) is rather rare operation and we can sacrifice its speed to solve the issues above. The access to other task namespaces is proposed to be performed like this: rcu_read_lock(); nsproxy = task_nsproxy(tsk); if (nsproxy != NULL) { / * * work with the namespaces here * e.g. get the reference on one of them * / } / * * NULL task_nsproxy() means that this task is * almost dead (zombie) * / rcu_read_unlock(); This patch has passed the review by Eric and Oleg :) and, of course, tested.

| * [IPV6]: Fix again the fl6_sock_lookup() fixed lockingPavel Emelyanov2007-10-18
| | | | | | | | | | | | | | | | | | YOSHIFUJI fairly pointed out, that the users increment should be done under the ip6_sk_fl_lock not to give IPV6_FL_A_PUT a chance to put this count to zero and release the flowlabel.

Allow to open up the connection again for the party which sent the RST packet.

| * [IPV6]: Fix race in ipv6_flowlabel_opt() when inserting two labelsPavel Emelyanov2007-10-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In the IPV6_FL_A_GET case the hash is checked for flowlabels with the given label. If it is not found, the lock, protecting the hash, is dropped to be re-get for writing. After this a newly allocated entry is inserted, but no checks are performed to catch a classical SMP race, when the conflicting label may be inserted on another cpu. Use the (currently unused) return value from fl_intern() to return the conflicting entry (if found) and re-check, whether we can reuse it (IPV6_FL_F_EXCL) or return -EEXISTS. Also add the comment, about why not re-lookup the current sock for conflicting flowlabel entry. Signed-off-by: Pavel Emelyanov <xemul@openvz.org> Signed-off-by: David S. Miller <davem@davemloft.net>
| * [IPV6]: Lost locking in fl6_sock_lookupPavel Emelyanov2007-10-18
| | | | | | | | | | | | | | | | | | | | | | This routine scans the ipv6_fl_list whose update is protected with the socket lock and the ip6_sk_fl_lock. Since the socket lock is not taken in the lookup, use the other one. Signed-off-by: Pavel Emelyanov <xemul@openvz.org> Signed-off-by: David S. Miller <davem@davemloft.net>
| * [IPV6]: Lost locking when inserting a flowlabel in ipv6_fl_listPavel Emelyanov2007-10-18
| | | | | | | | | | | | | | | | | | | | | | | | The new flowlabels should be inserted into the sock list under the ip6_sk_fl_lock. This was lost in one place. This list is naturally protected with the socket lock, but the fl6_sock_lookup() is called without it, so another protection is required.

| * [TCP]: Remove lost_retrans zero seqno special casesIlpo Järvinen2007-10-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Both high-sack detection and new lowest seq variables have unnecessary zero special case which are now removed by setting safe initial seqnos. This also fixes problem which caused zero received_upto being passed to tcp_mark_lost_retrans which confused after relations within the marker loop causing incorrect TCPCB_SACKED_RETRANS clearing. The problem was noticed because of a performance report from TAKANO Ryousei <takano@axe-inc.co.jp>.

| * [NET]: fix carrier-on bug?Jeff Garzik2007-10-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | While looking at a net driver with the following construct, if (!netif_carrier_ok(dev)) netif_carrier_on(dev); it stuck me that the netif_carrier_ok() check was redundant, since netif_carrier_on() checks bit __LINK_STATE_NOCARRIER anyway. This is the same reason why netif_queue_stopped() need not be called prior to netif_wake_queue(). This is true, but there is however an unwanted side effect from assuming that netif_carrier_on() can be called multiple times: it touches the watchdog, regardless of pre-existing carrier state. The fix: move watchdog-up inside the bit-cleared code path. Signed-off-by: Jeff Garzik <jgarzik@redhat.com> Signed-off-by: David S. Miller <davem@davemloft.net>

| * [IPSEC]: Rename mode to outer_mode and add inner_modeHerbert Xu2007-10-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds a new field to xfrm states called inner_mode. The existing mode object is renamed to outer_mode. This is the first part of an attempt to fix inter-family transforms. As it is we always use the outer family when determining which mode to use. As a result we may end up shoving IPv4 packets into netfilter6 and vice versa. What we really want is to use the inner family for the first part of outbound processing and the outer family for the second part. For inbound processing we'd use the opposite pairing. I've also added a check to prevent silly combinations such as transport mode with inter-family transforms. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S.
