b43: Fix memory leaks in b43_bus_dev_ssb_init and b43_bus_dev_bcma_init

2016-03-23T15:51:31Z

The memory allocated by kzalloc in b43_bus_dev_ssb_init and b43_bus_dev_bcma_init is not freed. This patch fixes the bug by adding kfree in b43_ssb_remove, b43_bcma_remove and error handling code of b43_bcma_probe. Thanks Michael for his suggestion.

brcmfmac: Remove waitqueue_active check

2016-03-10T12:57:56Z

We met a problem of pm_suspend when repeated closing/opening the lid on a Lenovo laptop (1/20 reproduce rate), below is the log: [ 199.735876] PM: Entering mem sleep [ 199.750516] e1000e: EEE TX LPI TIMER: 00000011 [ 199.856638] Trying to free nonexistent resource <000000000000d000-000000000000d0ff> [ 201.753566] brcmfmac: brcmf_pcie_suspend: Timeout on response for entering D3 substate [ 201.753581] pci_legacy_suspend(): brcmf_pcie_suspend+0x0/0x1f0 [brcmfmac] returns -5 [ 201.753585] dpm_run_callback(): pci_pm_suspend+0x0/0x160 returns -5 [ 201.753589] PM: Device 0000:04:00.0 failed to suspend async: error -5 Through debugging, we found when problem happens, it is not the device fails to enter D3, but the signal D3_ACK comes too early to pass the waitqueue_active() check. Just like this: brcmf_pcie_send_mb_data(devinfo, BRCMF_H2D_HOST_D3_INFORM); // signal is triggered here wait_event_timeout(devinfo->mbdata_resp_wait, devinfo->mbdata_completed, BRCMF_PCIE_MBDATA_TIMEOUT); So far I think it is safe to remove waitqueue_active check since there is only one place to trigger this signal (sending BRCMF_H2D_HOST_D3_INFORM). And it is not a problem calling wake_up event earlier than calling wait_event.

brcmfmac: integrate add_keyext in add_key

2016-03-07T12:15:57Z

brcmf_add_keyext is called when a key is configured for a specific mac address. This function is very similar to the calling function brcmf_add_key. Integrate this function and also use existing del_key function in case key is to be cleared.

brcmfmac: keep ARP and ND offload enabled during WOWL

2016-03-07T12:14:59Z

Currently ARP and ND (IPv6 Neigbor Discovery) offload get disabled on entering suspend. However when firmwares support the wowl_cap iovar then these offload routines can be kept enabled as they will work during WOWL as well.
