* phylib: Fix oops in suspend/resume pathsAnton Vorontsov2009-01-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Suspend/resume routines check for phydrv != NULL, but that is wrong because "phydrv" comes from container_of(drv). If drv is NULL, then container_of(drv) will return non-NULL result, and the checks won't work. The Freescale TBI PHYs are driver-less, so "drv" is NULL, and that leads to the following oops: Unable to handle kernel paging request for data at address 0xffffffe4 Faulting instruction address: 0xc0215554 Oops: Kernel access of bad area, sig: 11 [#1] [...] NIP [c0215554] mdio_bus_suspend+0x34/0x70 LR [c01cc508] suspend_device+0x258/0x2bc Call Trace: [cfad3da0] [cfad3db8] 0xcfad3db8 (unreliable) [cfad3db0] [c01cc508] suspend_device+0x258/0x2bc [cfad3dd0] [c01cc62c] dpm_suspend+0xc0/0x140 [cfad3e20] [c01cc6f4] device_suspend+0x48/0x5c [cfad3e40] [c0068dd8] suspend_devices_and_enter+0x8c/0x148 [cfad3e60] [c00690f8] enter_state+0x100/0x118 [cfad3e80] [c00691c0] state_store+0xb0/0xe4 [cfad3ea0] [c018c938] kobj_attr_store+0x24/0x3c [cfad3eb0] [c00ea9a8] flush_write_buffer+0x58/0x7c [cfad3ed0] [c00eadf0] sysfs_write_file+0x58/0xa0 [cfad3ef0] [c009e810] vfs_write+0xb4/0x16c [cfad3f10] [c009ed40] sys_write+0x4c/0x90 [cfad3f40] [c0014954] ret_from_syscall+0x0/0x38 [...] This patch fixes the issue, plus removes unneeded parentheses and fixes indentation level in mdio_bus_suspend().

* bnx2x: loopback test failureEilon Greenstein2009-01-22
| | | | | | | | | | | | A link change interrupt might be queued and activated after the loopback was set and it will cause the loopback to fail. The PHY lock should be kept until the loopback test is over. That implies that the bnx2x_test_link should used within the loopback function and not bnx2x_wait_for_link since that function also takes the PHY link Signed-off-by: Eilon Greenstein <eilong@broadcom.com> Signed-off-by: David S.

* rt2x00: Fix TX rate short preamble detectionIvo van Doorn2009-01-22
| | | | | | | | | | | | | Mac80211 provides 2 structures to handle bitrates, namely ieee80211_rate and ieee80211_tx_rate. To determine the short preamble mode for an outgoing frame, the flag IEEE80211_TX_RC_USE_SHORT_PREAMBLE must be checked on ieee80211_tx_rate and not ieee80211_rate (which rt2x00 did).

| * rt2x00: fix a wrong parameter for __test_and_clear_bit() in rt2x00rfkill_free().Rami Rosen2009-01-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When running modprobe rt73usb, and then rmmod rt73usb, and then iwconfig, the wlan0 device does not disappear. When repeating this process again, we get a kernel Oops errors and "BUG: unable to handle kernel paging request..." message in the kernel log. The reason for this is that there is an error in rt2x00rfkill_free(), which is called in the process of removing the device (rt2x00lib_remove_dev() in rt2x00dev.c). rt2x00rfkill_free() clears the RFKILL_STATE_ALLOCATED bit , which is bit number 1 () in rt2x00dev->flags instead of in rt2x00dev->rfkill_state. As a result, when checking the DEVICE_STATE_REGISTERED_HW bit (bit number 1 in rt2x00dev->flags) in rt2x00lib_remove_hw() it is **unset**, and we wrongly **don't** call ieee80211_unregister_hw(). This patch corrects this: the parameter for __test_and_clear_bit() in rt2x00rfkill_free() should be &rt2x00dev->rfkill_state and not &rt2x00dev->flags.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Data structures that come over the wire from the WLAN firmware must be packed. This fixes alignment problems on the blackfin architecture and, reportedly, on the AVR32. This is a replacement for the previous version of this patch which had also explicitly used get_unaligned_ macros. As Johannes Berg pointed out, these macros were unnecessary.

* | wimax/i2400m: error paths that need to free an skb should use kfree_skb()Inaky Perez-Gonzalez2009-01-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Roel Kluin reported a bug in two error paths where skbs were wrongly being freed using kfree(). He provided a fix where it was replaced to kfree_skb(), as it should be. However, in i2400mu_rx(), the error path was missing returning an indication of the failure. Changed to reset rx_skb to NULL and return it to the caller, i2400mu_rxd(). It will be treated as a transient error and just ignore the packet. Depending on the buffering conditions inside the device, the data packet might be dropped or the device will signal the host again for data-ready-to-read and the host will retry.

* | mv643xx_eth: prevent interrupt storm on ifconfig downGabriel Paubert2009-01-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Contrary to what the docs say, the 'extended interrupt cause' bit in the interrupt cause register (bit 1) appears to not be maskable on at least some of the mv643xx_eth platforms, making writing zeroes to the interrupt mask register but not the extended interrupt mask register insufficient to stop interrupts from occuring. Therefore, also write zeroes to the extended interrupt mask register when shutting down the port. This fixes the interrupt storm seen on the Pegasos board when shutting down the interface.

The non-special multicast filter table (for multicast addresses that are not of the form 01:00:5e:00:00:xx) consists of 256 hash table buckets organised as 64 32-bit words, where the 'accept' bits are in the LSB of each byte, so in bits 24 16 8 0 of each 32-bit word. The old code got this right, but the referenced commit broke this by using bits 3 2 1 0 instead. This commit fixes this up.

* | tg3: Fix firmware loadingMatt Carlson2009-01-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch modifies how the tg3 driver handles device firmware. The patch starts by consolidating David Woodhouse's earlier patch under the same name. Specifically, the patch moves the request_firmware call into a separate tg3_request_firmware() function and calls that function from tg3_open() rather than tg3_init_one(). The patch then goes on to limit the number of devices that will make request_firmware calls. The original firmware patch unnecessarily requested TSO firmware for devices that did not need it. This patch reduces the set of devices making TSO firmware patches to approximately the following device set : 5703, 5704, and 5705. Finally, the patch reduces the effects of a request_firmware() failure. For those devices that are requesting TSO firmware, the driver will turn off the TSO capability. If TSO firmware becomes available at a later time, the device can be closed and then opened again to reacquire the TSO capability.

* | macb: avoid lockup when TGO during underrunRichard Röjfors2009-01-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In rare cases when an underrun occur, all macb buffers where consumed and the netif_queue was stopped infinitely. This happens then the TGO (transfer ongoing) bit in the TSR is set (and UND). It seems like clening up after the underrun makes the driver and the macb hardware end up in an inconsistent state. The result of this is that in the following calls to macb_tx no TX buffers are released -> the netif_queue was stopped, and never woken up again. The solution is to disable the transmitter, if TGO is set, before clening up after the underrun, and re-enable the transmitter when the cleaning up is done.
