* [Bluetooth]: Remove the usage of /proc completelyMarcel Holtmann2005-11-08
| | | | | | | | | This patch removes all relics of the /proc usage from the Bluetooth subsystem core and its upper layers. All the previous information are now available via /sys/class/bluetooth through appropriate functions. Signed-off-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: David S.

* [IPV4]: Fix ip_queue_xmit identity increment for TSO packetsHerbert Xu2005-11-08
| | | | | | | | | | | | When ip_queue_xmit calls ip_select_ident_more for IP identity selection it gives it the wrong packet count for TSO packets. The ip_select_* functions expect one less than the number of packets, so we need to subtract one for TSO packets. This bug was diagnosed and fixed by Tom Young.

* [IPVS]: fix connection leak if expire_nodest_conn=1Julian Anastasov2005-11-08
| | | | | | | | | | | | | | | | There was a fix in 2.6.13 that changed the behaviour of ip_vs_conn_expire_now function not to put reference to connection, its callers should hold write lock or connection refcnt. But we forgot to convert one caller, when the real server for connection is unavailable caller should put the connection reference. It happens only when sysctl var expire_nodest_conn is set to 1 and such connections never expire. Thanks to Roberto Nibali who found the problem and tested a 2.4.32-rc2 patch, which is equal to this 2.6 version. Patch for 2.4 is already sent to Marcelo.

| | * [PKT_SCHED]: (G)RED: Introduce hard droppingThomas Graf2005-11-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Introduces a new flag TC_RED_HARDDROP which specifies that if ECN marking is enabled packets should still be dropped once the average queue length exceeds the maximum threshold. This _may_ help to avoid global synchronisation during small bursts of peers advertising but not caring about ECN. Use this option very carefully, it does more harm than good if (qth_max - qth_min) does not cover at least two average burst cycles. The difference to the current behaviour, in which we'd run into the hard queue limit, is that due to the low pass filter of RED short bursts are less likely to cause a global synchronisation.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since we are no longer depending on the default VQ to be always allocated we can leave it up to the user to actually create it. This gives the user the ability to leave it out on purpose and enqueue packets directly to the device without applying the RED algorithm.

| | * [PKT_SCHED]: GRED: Dont abuse default VQ for equalizingThomas Graf2005-11-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Introduces a new red parameter set for use in equalize mode, although only the qavg variable and the idle period marker are being used for now this makes it possible to allow a separate parameter set to be used for equalize later on. The use of this separate parameter set fixes a bogus start of an idle period in gred_drop() which did start an idle period on the default VQ even if equalize mode was disabled.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Qdiscs are not supposed to reset statistics in reset() and while changing parameters.

We now differentiate between probability marks and forced marks but sum them together again to not break backwards compatibility. This brings GRED back to the level of RED and improves the accuracy of the averge queue length calculations when stab suggests a zero shift.

Adds missing validations for table definition: MAX_DPs > DPs > 0 and def_DP < DPs thus fixing possible invalid memory reference oopses. Only root could do it but having a typo crashing the machine is a bit hard. Adds missing locking while changing the table definition, the operation of changing the number of DPs and removing shadowed VQs may not be interrupted by a dequeue.

| | * [PKT_SCHED]: GRED: Cleanup equalize flag and add new WRED mode detectionThomas Graf2005-11-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Introduces a flags variable using bitops and transforms eqp to use it. Converts the conditions of the form (wred && rio) to (wred) since wred can only be enabled in rio mode anyway. The patch also improves WRED mode detection. The current behaviour does not allow WRED mode to be turned off again without removing the whole qdisc first. The new algorithm checks each VQ against each other looking for equal priorities every time a VQ is changed or added. The performance is poor, O(n**2), but it's used only during administrative tasks and the number of VQs is strictly limited.

| * | [NET]: Fix race condition in sk_stream_wait_connectHerbert Xu2005-11-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When sk_stream_wait_connect detects a state transition to ESTABLISHED or CLOSE_WAIT prior to it going to sleep, it will return without calling finish_wait and decrementing sk_write_pending. This may result in crashes and other unintended behaviour. The fix is to always call finish_wait and update sk_write_pending since it is safe to do so even if the wait entry is no longer on the queue. This bug was tracked down with the help of Alex Sidorenko and the fix is also based on his suggestion.

Introduce a special case version of FIFO that queues packets in order based on the netem delay. Since netem is classful, those users that don't want jitter based reordering can just insert a pfifo instead of the default.
