When a new wimax_dev is created, it's state has to be __WIMAX_ST_NULL until wimax_dev_add() is succesfully called. This allows calls into the stack that happen before said time to be rejected. Until now, the state was being set (by mistake) to UNINITIALIZED, which was allowing calls such as wimax_report_rfkill_hw() to go through even when a call to wimax_dev_add() had failed; that was causing an oops when touching uninitialized data. This situation is normal when the device starts reporting state before the whole initialization has been completed. It just has to be dealt with.

When sending a message to user space using wimax_msg(), if nla_put() fails, correctly interpret the return code from wimax_msg_alloc() as an err ptr and return the error code instead of crashing (as it is assuming than non-NULL means the pointer is ok). Signed-off-by:

Setting the name of a sysfs device has to be done in a context that can actually sleep. It allocates its memory with GFP_KERNEL. Previously it was a static (size limited) string and that got changed to accommodate longer device names. So move the dev_set_name() just before calling device_add() which is executed in a work queue. This fixes the following error: [ 110.012125] BUG: sleeping function called from invalid context at mm/slub.c:1595 [ 110.012135] in_atomic(): 1, irqs_disabled(): 0, pid: 0, name: swapper [ 110.012141] 2 locks held by swapper/0: [ 110.012145] #0: (hci_task_lock){++.-.+}, at: [<ffffffffa01f822f>] hci_rx_task+0x2f/0x2d0 [bluetooth] [ 110.012173] #1: (&hdev->lock){+.-.+.}, at: [<ffffffffa01fb9e2>] hci_event_packet+0x72/0x25c0 [bluetooth] [ 110.012198] Pid: 0, comm: swapper Tainted: G W 2.6.30-rc4-g953cdaa #1 [ 110.012203] Call Trace: [ 110.012207] <IRQ> [<ffffffff8023eabd>] __might_sleep+0x14d/0x170 [ 110.012228] [<ffffffff802cfbe1>] __kmalloc+0x111/0x170 [ 110.012239] [<ffffffff803c2094>] kvasprintf+0x64/0xb0 [ 110.012248] [<ffffffff803b7a5b>] kobject_set_name_vargs+0x3b/0xa0 [ 110.012257] [<ffffffff80465326>] dev_set_name+0x76/0xa0 [ 110.012273] [<ffffffffa01fb9e2>] ? hci_event_packet+0x72/0x25c0 [bluetooth] [ 110.012289] [<ffffffffa01ffc1d>] hci_conn_add_sysfs+0x3d/0x70 [bluetooth] [ 110.012303] [<ffffffffa01fba2c>] hci_event_packet+0xbc/0x25c0 [bluetooth] [ 110.012312] [<ffffffff80516eb0>] ? sock_def_readable+0x80/0xa0 [ 110.012328] [<ffffffffa01fee0c>] ? hci_send_to_sock+0xfc/0x1c0 [bluetooth] [ 110.012343] [<ffffffff80516eb0>] ? sock_def_readable+0x80/0xa0 [ 110.012347] [<ffffffff805e88c5>] ? _read_unlock+0x75/0x80 [ 110.012354] [<ffffffffa01fee0c>] ? hci_send_to_sock+0xfc/0x1c0 [bluetooth] [ 110.012360] [<ffffffffa01f8403>] hci_rx_task+0x203/0x2d0 [bluetooth] [ 110.012365] [<ffffffff80250ab5>] tasklet_action+0xb5/0x160 [ 110.012369] [<ffffffff8025116c>] __do_softirq+0x9c/0x150 [ 110.012372] [<ffffffff805e850f>] ? _spin_unlock+0x3f/0x80 [ 110.012376] [<ffffffff8020cbbc>] call_softirq+0x1c/0x30 [ 110.012380] [<ffffffff8020f01d>] do_softirq+0x8d/0xe0 [ 110.012383] [<ffffffff80250df5>] irq_exit+0xc5/0xe0 [ 110.012386] [<ffffffff8020e71d>] do_IRQ+0x9d/0x120 [ 110.012389] [<ffffffff8020c3d3>] ret_from_intr+0x0/0xf [ 110.012391] <EOI> [<ffffffff80431832>] ? acpi_idle_enter_bm+0x264/0x2a6 [ 110.012399] [<ffffffff80431828>] ? acpi_idle_enter_bm+0x25a/0x2a6 [ 110.012403] [<ffffffff804f50d5>] ? cpuidle_idle_call+0xc5/0x130 [ 110.012407] [<ffffffff8020a4b4>] ? cpu_idle+0xc4/0x130 [ 110.012411] [<ffffffff805d2268>] ? rest_init+0x88/0xb0 [ 110.012416] [<ffffffff807e2fbd>] ? start_kernel+0x3b5/0x412 [ 110.012420] [<ffffffff807e2281>] ? x86_64_start_reservations+0x91/0xb5 [ 110.012424] [<ffffffff807e2394>] ? x86_64_start_kernel+0xef/0x11b Based on a report by Davide Pesavento <davidepesa@gmail.com> Signed-off-by:Marcel Holtmann <marcel@holtmann.org> Tested-by:

This patch fixes a problem when you use 32 nodes in the cluster match: % iptables -I PREROUTING -t mangle -i eth0 -m cluster \ --cluster-total-nodes 32 --cluster-local-node 32 \ --cluster-hash-seed 0xdeadbeef -j MARK --set-mark 0xffff iptables: Invalid argument. Run `dmesg' for more information. % dmesg | tail -1 xt_cluster: this node mask cannot be higher than the total number of nodes The problem is related to this checking: if (info->node_mask >= (1 << info->total_nodes)) { printk(KERN_ERR "xt_cluster: this node mask cannot be " "higher than the total number of nodes\n"); return false; } (1 << 32) is 1. Thus, the checking fails. BTW, I said this before but I insist: I have only tested the cluster match with 2 nodes getting ~45% extra performance in an active-active setup. The maximum limit of 32 nodes is still completely arbitrary. I'd really appreciate if people that have more nodes in their setups let me know. Signed-off-by: -

a recent fix to e1000 (commit 15b2bee2) caused KVM/QEMU/VMware based virtualized e1000 interfaces to begin failing when resetting. This is because the driver in a virtual environment doesn't get to run instructions *AT ALL* when an interrupt is asserted. The interrupt code runs immediately and this recent bug fix allows an interrupt to be possible when the interrupt handler will reject it (due to the new code), when being called from any path in the driver that holds the E1000_RESETTING flag. the driver should use the __E1000_DOWN flag instead of the __E1000_RESETTING flag to prevent interrupt execution while reconfiguring the hardware.

Due to a semantic changes in flush_workqueue() the current approach of synchronizing the sysfs handling for connections doesn't work anymore. The whole approach is actually fully broken and based on assumptions that are no longer valid. With the introduction of Simple Pairing support, the creation of low-level ACL links got changed. This change invalidates the reason why in the past two independent work queues have been used for adding/removing sysfs devices. The adding of the actual sysfs device is now postponed until the host controller successfully assigns an unique handle to that link. So the real synchronization happens inside the controller and not the host. The only left-over problem is that some internals of the sysfs device handling are not initialized ahead of time. This leaves potential access to invalid data and can cause various NULL pointer dereferences. To fix this a new function makes sure that all sysfs details are initialized when an connection attempt is made. The actual sysfs device is only registered when the connection has been successfully established. To avoid a race condition with the registration, the check if a device is registered has been moved into the removal work. As an extra protection two flush_work() calls are left in place to make sure a previous add/del work has been completed first. Based on a report by Marc Pignat <marc.pignat@hevs.ch> Signed-off-by:

pid doesn't count with some band having more bitrates than the one associated the first time. Fix that by counting the maximal available bitrate count and allocate big enough space. Secondly, fix touching uninitialized memory which causes panics. Index sucked from this random memory points to the hell. The fix is to sort the rates on each band change. Signed-off-by:

minstrel doesn't count max rate count in fact, since it doesn't use a loop variable `i' and hence allocs space only for bitrates found in the first band. Fix it by involving the `i' as an index so that it traverses all the bands now and finds the real max bitrate count. Signed-off-by:

We forgot to lock using the cfg80211_mutex in wiphy_apply_custom_regulatory(). Without the lock there is possible race between processing a reply from CRDA and a driver calling wiphy_apply_custom_regulatory(). During the processing of the reply from CRDA we free last_request and wiphy_apply_custom_regulatory() eventually accesses an element from last_request in the through freq_reg_info_regd(). This is very difficult to reproduce (I haven't), it takes us 3 hours and you need to be banging hard, but the race is obvious by looking at the code.

We need to be symmetrical in what is done when key is set and cleared. This is important wrt the key flags as they are used during key clearing and if they are not set when the key is set the key cannot be cleared completely. This addresses the many occurences of the WARN found in iwl_set_tkip_dynamic_key_info() and tracked in http://www.kerneloops.org/searchweek.php?search=iwl_set_dynamic_key If calling iwl_set_tkip_dynamic_key_info()/iwl_remove_dynamic_key() pair a few times in a row will cause that we run out of key space. This is because the index stored in the key flags is used by iwl_remove_dynamic_key() to decide if it should remove the key. Unfortunately the key flags, and hence the key index is currently only set at the time the key is written to the device (in iwl_update_tkip_key()) and _not_ in iwl_set_tkip_dynamic_key_info(). Fix this by setting flags in iwl_set_tkip_dynamic_key_info(). Signed-off-by:

This introduces a CDC Ethernet Emulation Model (EEM) host side driver to support USB EEM devices. EEM is different from the Ethernet Control Model (ECM) currently supported by the "CDC Ethernet" driver. One key difference is that it doesn't require of USB interface alternate settings to manage interface state; some maldesigned hardware can't handle that part of USB. It also avoids a separate USB interface for control and status updates.

Filter priorities in all other cases only use the upper 16 bits of the u32 'prio' field of 'struct tcf_proto', but when the kernel generates the priority of a filter is saves all 32 bits which can result in incorrect lookup failures when a filter needs to be deleted or modified.

We were avoiding calling sg_init* on scatterlists passed into virtnet_send_command to prevent extraneous end markers. This caused build warnings for uninitialized variables. Cleanup the code to create proper scatterlists. Signed-off-by:

LAN9512 and LAN9514 are USB hubs with an integrated 10/100 ethernet controller. Logically this looks like an ethernet controller (similar to LAN9500) permanently attached to one of the hub's downstream ports. This patch adds the usb device id of the new ethernet controller to the smsc95xx driver. This id is the same in both new devices. Signed-off-by:

SMSC LAN9500 has dual purpose GPIO/LED pins, and by default at power-on these are configured as GPIOs. This means that if LEDs are fitted they won't ever light. This patch sets them to be LED outputs for speed, duplex and link/activity. Signed-off-by:

When netconsole is loaded and a network interface fades away (e.g. on rmmod $interface_driver_module) the rmmod remains stuck and some locks are taken that prevent any additional module loading/unloading as well as interface up/down changes. In addition kernel logs (and console) get flooded at 10s interval with [ 122.464065] unregister_netdevice: waiting for eth0 to become free. Usage count = 1 [ 132.704059] unregister_netdevice: waiting for eth0 to become free. Usage count = 1 This patch lets netconsole take NETDEV_UNREGISTER event into account and release the affected interface if it was in use. Signed-off-by:
