* [PATCH] libertas: remove fw.cHolger Schurig2007-10-10
| | | | | | | | | | | | | | Firmware download is quite different for different hardware. The SDIO and CF cards have two flat files that need to be downloaded, whereas the USB driver needs only one file, but with an internal structure. The code that handles this (USB only) structured file is currently in fw.c. This patch moves this code into if_usb.c. The remaining functions in fw.c have not much to do with firmware, they are various card- and network-stack initialisation functions. I've moved them into main.c.

* [PATCH] libertas: simplify and clean up data rate handlingDan Williams2007-10-10
| | | | | | | | | | | | | | | | | | | Remove unused/duplicated fields and consolidate static data rate arrays, for example the libertas_supported_rates[] and datarates[] arrays in the bss_descriptor structure, and the libertas_supported_rates field in the wlan_adapter structure. Introduce libertas_fw_index_to_data_rate and libertas_data_rate_to_fw_index functions and use them everywhere firmware requires a rate index rather than a rate array. The firmware requires the 4 basic rates to have the MSB set, but most other stuff doesn't, like WEXT and mesh ioctls. Therefore, only set the MSB on basic rates when pushing rate arrays to firmware instead of doing a ton of (rate & 0x7f) everywhere.

* [PATCH] libertas: specific mesh scan for mshX interfaceLuis Carlos Cobo2007-10-10
| | | | | | | | | | | | | | | | | | | With this patch, scanning with mshX interface will only return mesh networks. To differentiate them, a specific mesh IE in beacons/probe responses is used. This IE has been introduced in firmware release 5.110.14. Note: Even though there can be at most a single mesh per channel, this scan might return several networks in the same channel. If all nodes in a mesh network are associated to an AP, they won't produce beacons/probe responses, thus the network will not be listed. This will be fixed in future firmware releases. Scan on ethX interface is not filtered, so it will list both mesh and non-mesh networks. Signed-off-by: Luis Carlos Cobo <luisca@cozybit.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

In fact, it is unlikely to be of much use as-is because the default key index isn't something that the driver can do much with without knowing which interface it was for etc. And if it needs the key index for the transmitted frame, it can get it by keeping a reference to the key_conf structure and looking it up by hw_key_idx.

* [MAC80211]: fix race conditions with keysJohannes Berg2007-10-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | During receive processing, we select the key long before using it and because there's no locking it is possible that we kfree() the key after having selected it but before using it for crypto operations. Obviously, this is bad. Secondly, during transmit processing, there are two possible races: We have a similar race between select_key() and using it for encryption, but we also have a race here between select_key() and hardware encryption (both when a key is removed.) This patch solves these issues by using RCU: when a key is to be freed, we first remove the pointer from the appropriate places (sdata->keys, sdata->default_key, sta->key) using rcu_assign_pointer() and then synchronize_rcu(). Then, we can safely kfree() the key and remove it from the hardware. There's a window here where the hardware may still be using it for decryption, but we can't work around that without having two hardware callbacks, one to disable the key for RX and one to disable it for TX; but the worst thing that will happen is that we receive a packet decrypted that we don't find a key for any more and then drop it. When we add a key, we first need to upload it to the hardware and then, using rcu_assign_pointer() again, link it into our structures. In the code using keys (TX/RX paths) we use rcu_dereference() to get the key and enclose the whole tx/rx section in a rcu_read_lock() ... rcu_read_unlock() block. Because we've uploaded the key to hardware before linking it into internal structures, we can guarantee that it is valid once get to into tx(). One possible race condition remains, however: when we have hardware acceleration enabled and the driver shuts down the queues, we end up queueing the frame. If now somebody removes the key, the key will be removed from hwaccel and then then driver will be asked to encrypt the frame with a key index that has been removed. Hence, drivers will need to be aware that the hw_key_index they are passed might not be under all circumstances. Most drivers will, however, simply ignore that condition and encrypt the frame with the selected key anyway, this only results in a frame being encrypted with a wrong key or dropped (rightfully) because the key was not valid. There isn't much we can do about it unless we want to walk the pending frame queue every time a key is removed and remove all frames that used it. This race condition, however, will most likely be solved once we add multiqueue support to mac80211 because then frames will be queued further up the stack instead of after being processed.

* [IPV4]: Convert rt_check_expire() from softirq processing to workqueue.Eric Dumazet2007-10-10
| | | | | | | | | | | | | | | | | | | | | | | | On loaded/big hosts, rt_check_expire() if of litle use, because it generally breaks out of its main loop because of a jiffies change. It can take a long time (read : timer invocations) to actually scan the whole hash table, freeing unused entries. Converting it to use a workqueue instead of softirq is a nice move because we can allow rt_check_expire() to do the scan it is supposed to do, without hogging the CPU. This has an impact on the average number of entries in cache, reducing ram usage. Cache is more responsive to parameter changes (/proc/sys/net/ipv4/route/gc_timeout and /proc/sys/net/ipv4/route/gc_interval) Note: Maybe the default value of gc_interval (60 seconds) is too high, since this means we actually need 5 (300/60) invocations to scan the whole table.

* [NET]: Fix race when opening a proc file while a network namespace is exiting.Eric W. Biederman2007-10-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | The problem: proc_net files remember which network namespace the are against but do not remember hold a reference count (as that would pin the network namespace). So we currently have a small window where the reference count on a network namespace may be incremented when opening a /proc file when it has already gone to zero. To fix this introduce maybe_get_net and get_proc_net. maybe_get_net increments the network namespace reference count only if it is greater then zero, ensuring we don't increment a reference count after it has gone to zero. get_proc_net handles all of the magic to go from a proc inode to the network namespace instance and call maybe_get_net on it. PROC_NET the old accessor is removed so that we don't get confused and use the wrong helper function. Then I fix up the callers to use get_proc_net and handle the case case where get_proc_net returns NULL. In that case I return -ENXIO because effectively the network namespace has already gone away so the files we are trying to access don't exist anymore. Signed-off-by: Eric W.

| | | | | | | | | | | | | | | This is done in order to, add support to changing the rate table to use the upper-boundry L2T (length to time) value. Currently we use the lower-boundry, which result in under-estimating the actual bandwidth usage. Extend the tc_ratespec struct, with two parameters: 1) "cell_align" that allow adjusting the alignment of the rate table. 2) "overhead" that allow adding a packet overhead before the lookup.

* [NET_SCHED]: Cleanup L2T macros and handle oversized packetsJesper Dangaard Brouer2007-10-10
| | | | | | | | | | | Change L2T (length to time) macros, in all rate based schedulers, to call a common function qdisc_l2t() that does the rate table lookup. This function handles if the packet size lookup is larger than the rate table, which often occurs with TSO enabled.
