mt76: dma: fix buffer unmap with non-linear skbs

2019-11-12T18:28:11Z

[ Upstream commit 7bd0650be63cbb9e45e394d689c81365fe48e495 ] mt76 dma layer is supposed to unmap skb data buffers while keep txwi mapped on hw dma ring. At the moment mt76 wrongly unmap txwi or does not unmap data fragments in even positions for non-linear skbs. This issue may result in hw hangs with A-MSDU if the system relies on IOMMU or SWIOTLB. Fix this behaviour properly unmapping data fragments on non-linear skbs.

mt76: mt7615: fix mt7615 firmware path definitions

[ Upstream commit 9d4d0d06bbf9f7e576b0ebbb2f77672d0fc7f503 ] mt7615 patch/n9/cr4 firmwares are available in mediatek folder in linux-firmware repository. Because of this mt7615 won't work on regular distributions like Ubuntu. Fix path definitions. Moreover remove useless firmware name pointers and use definitions directly Fixes: 04b8e65922f6 ("mt76: add mac80211 driver for MT7615 PCIe-based chipsets") Cc: stable@vger.kernel.org Signed-off-by: Lorenzo Bianconi Signed-off-by: Kalle Valo Signed-off-by: Sasha Levin

mt76: round up length on mt76_wr_copy

2019-10-05T13:12:27Z

commit 850e8f6fbd5d0003b0f1119d19a01c6fef1644e2 upstream. When beacon length is not a multiple of 4, the beacon could be sent with the last 1-3 bytes corrupted. The skb data is guaranteed to have enough room for reading beyond the end, because it is always followed by skb_shared_info, so rounding up is safe. All other callers of mt76_wr_copy have multiple-of-4 length already. Cc: stable@vger.kernel.org Signed-off-by: Felix Fietkau Signed-off-by: Greg Kroah-Hartman

mt76: mt76x0e: disable 5GHz band for MT7630E

2019-09-03T13:49:29Z

MT7630E hardware does support 5GHz, but we do not properly configure phy for 5GHz channels. Scanning at this band not only do not show any APs but also can hang the firmware. Since vendor reference driver do not support 5GHz we don't know how properly configure 5GHz channels. So disable this band for MT7630E .

mt76: mt76x0e: don't use hw encryption for MT7630E

2019-09-03T13:48:43Z

Since 41634aa8d6db ("mt76: only schedule txqs from the tx tasklet") I can observe firmware hangs on MT7630E on station mode: tx stop functioning after minor activity (rx keep working) and on module unload device fail to stop with messages: [ 5446.141413] mt76x0e 0000:06:00.0: TX DMA did not stop [ 5449.176764] mt76x0e 0000:06:00.0: TX DMA did not stop Loading module again results in failure to associate with AP. Only machine power off / power on cycle can make device work again. It's unclear why commit 41634aa8d6db causes the problem, but it is related to HW encryption. Since issue is a firmware hang, that is super hard to debug, just disable HW encryption as fix for the issue.
