The interrupt handler schedules a workqueue which acquires a mutex that ks8851_net_stop() also acquires before flushing the workqueue. Previously lockdep wouldn't be able to find this problem but now that it has the support we can trigger this lockdep warning by rmmoding the driver after an ifconfig up. Fix the possible deadlock by disabling the interrupts in the chip and then release the lock across the workqueue flushing. The mutex is only there to proect the registers anyway so this should be ok. ======================================================= [ INFO: possible circular locking dependency detected ] 3.0.21-00021-g8b33780-dirty #2911 ------------------------------------------------------- rmmod/125 is trying to acquire lock: ((&ks->irq_work)){+.+...}, at: [<c019e0b8>] flush_work+0x0/0xac but task is already holding lock: (&ks->lock){+.+...}, at: [<bf00b850>] ks8851_net_stop+0x64/0x138 [ks8851] which lock already depends on the new lock. the existing dependency chain (in reverse order) is: -> #1 (&ks->lock){+.+...}: [<c01b89c8>] __lock_acquire+0x940/0x9f8 [<c01b9058>] lock_acquire+0x10c/0x130 [<c083dbec>] mutex_lock_nested+0x68/0x3dc [<bf00bd48>] ks8851_irq_work+0x24/0x46c [ks8851] [<c019c580>] process_one_work+0x2d8/0x518 [<c019cb98>] worker_thread+0x220/0x3a0 [<c01a2ad4>] kthread+0x88/0x94 [<c0107008>] kernel_thread_exit+0x0/0x8 -> #0 ((&ks->irq_work)){+.+...}: [<c01b7984>] validate_chain+0x914/0x1018 [<c01b89c8>] __lock_acquire+0x940/0x9f8 [<c01b9058>] lock_acquire+0x10c/0x130 [<c019e104>] flush_work+0x4c/0xac [<bf00b858>] ks8851_net_stop+0x6c/0x138 [ks8851] [<c06b209c>] __dev_close_many+0x98/0xcc [<c06b2174>] dev_close_many+0x68/0xd0 [<c06b22ec>] rollback_registered_many+0xcc/0x2b8 [<c06b2554>] rollback_registered+0x28/0x34 [<c06b25b8>] unregister_netdevice_queue+0x58/0x7c [<c06b25f4>] unregister_netdev+0x18/0x20 [<bf00c1f4>] ks8851_remove+0x64/0xb4 [ks8851] [<c049ddf0>] spi_drv_remove+0x18/0x1c [<c0468e98>] __device_release_driver+0x7c/0xbc [<c0468f64>] driver_detach+0x8c/0xb4 [<c0467f00>] bus_remove_driver+0xb8/0xe8 [<c01c1d20>] sys_delete_module+0x1e8/0x27c [<c0105ec0>] ret_fast_syscall+0x0/0x3c other info that might help us debug this: Possible unsafe locking scenario: CPU0 CPU1 ---- ---- lock(&ks->lock); lock((&ks->irq_work)); lock(&ks->lock); lock((&ks->irq_work)); *** DEADLOCK *** 4 locks held by rmmod/125: #0: (&__lockdep_no_validate__){+.+.+.}, at: [<c0468f44>] driver_detach+0x6c/0xb4 #1: (&__lockdep_no_validate__){+.+.+.}, at: [<c0468f50>] driver_detach+0x78/0xb4 #2: (rtnl_mutex){+.+.+.}, at: [<c06b25e8>] unregister_netdev+0xc/0x20 #3: (&ks->lock){+.+...}, at: [<bf00b850>] ks8851_net_stop+0x64/0x138 [ks8851] Cc: Ben Dooks <ben-linux@fluff.org> Signed-off-by: Stephen Boyd <sboyd@codeaurora.org> Signed-off-by: David S.

There are also multiple possible USB interface configurations in each mode, some providing more than one wwan interface.

| | * | | ixgbe: Identify FCoE rings earlier to resolve memory corruption w/ FCoEAlexander Duyck2012-04-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch makes it so that we identify FCoE rings earlier than ixgbe_set_rx_buffer_len. Instead we identify the Rx FCoE rings at allocation time in ixgbe_alloc_q_vector. The motivation behind this change is to avoid memory corruption when FCoE is enabled. Without this change we were initializing the rings at 0, and 2K on systems with 4K pages, then when we bumped the buffer size to 4K with order 1 pages we were accessing offsets 2K and 6K instead of 0 and 4K. This was resulting in memory corruptions.

This patch adds an additional check whether the operation was done before actually returning -ETIMEDOUT. To reproduce this bug, flood ping the device, e.g., ping -f -l 1000 After some time, a "timed out waiting for user access" warning may appear. And even worse, link may go down since the PHY reported a timeout.

| |/ / / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In register_netdevice(), when ndo_init() is successful and later some error occurred, ndo_uninit() will be called. So dummy deivce is desirable to implement ndo_uninit() method to free percpu stats for this case. And, ndo_uninit() is also called along with dev->destructor() when device is unregistered, so in order to prevent dev->dstats from being freed twice, dev->destructor is modified to free_netdev().

Support includes the following: 1. Configure vif parameters in firmware (default vlan, vif id, default priority, allowed priorities) according to values received from NIC. 2. Configure FW to strip/add default vlan according to afex vlan mode. 3. Notify link up to OS only after vif is fully initialized. 4. Support vif list set/get requests and configure FW accordingly. 5. Supply afex statistics upon request from NIC. 6. Special handling to L2 interface in case of FCoE vif.
