2019-05-01mt76usb: use usb_dev private dataStanislaw Gruszka
Setup usb device private data. This allows to remove mt76u_buf->dev and simplify some routines as no longer we need to get usb device through usb interface. Signed-off-by: Stanislaw Gruszka <sgruszka@redhat.com> Signed-off-by: Felix Fietkau <nbd@nbd.name>

2018-11-30mt76: add support for reporting tx status with skbFelix Fietkau
MT76x2/MT76x0 has somewhat unreliable tx status reporting, and for that reason the driver currently does not report per-skb tx ack status at all. This breaks things like client idle polling, which relies on the tx ack status of a transmitted nullfunc frame. This patch adds code to report skb-attached tx status if requested by mac80211 or the rate control module. Since tx status is polled from a simple FIFO register, the code needs to account for the possibility of tx status events getting lost. The code keeps a list of skbs for which tx status is required and passes them to mac80211 once tx status has been filled in and the DMA queue is done with it. If a tx status event is not received after one second, the status rates are cleared, and a succesful ACK is indicated to avoid spurious disassoc during assoc or client polling.

2018-10-05treewide: Replace more open-coded allocation size multiplicationsKees Cook
As done treewide earlier, this catches several more open-coded allocation size calculations that were added to the kernel during the merge window. This performs the following mechanical transformations using Coccinelle: kvmalloc(a * b, ...) -> kvmalloc_array(a, b, ...) kvzalloc(a * b, ...) -> kvcalloc(a, b, ...) devm_kzalloc(..., a * b, ...) -> devm_kcalloc(..., a, b, ...)

2018-10-05mt76: fix frag length allocation for usbStanislaw Gruszka
This is correct fix for c12128ce44b0 ("mt76: use a per rx queue page fragment cache"). We use wrong length when we allocate segments for MCU transmissions, which require bigger segment size than e->buf_size. Commit 481bb0432414 ("mt76: usb: make rx page_frag_cache access atomic") partially solved the problem or actually mask it by changing mt76u_mcu_init_rx() and mt76u_alloc_queues() sequence, so e->buf_size become non zero any longer, but still not big enough to handle MCU data. Patch fixes memory corruption which can manifest itself as random, not easy to reproduce crashes, during mt76 driver load or unload.

2018-09-19mt76: use a per rx queue page fragment cacheFelix Fietkau
Using the NAPI or netdev frag cache along with other drivers can lead to 32 KiB pages being held for a long time, despite only being used for very few page fragments. This can happen if the driver grabs one or two fragments for rx ring refill, while other drivers use (and free up) the remaining fragments. The 32 KiB higher-order page can only be freed once all users have freed their fragments. Depending on the traffic patterns, this can waste a lot of memory and look a lot like a memory leak.

Move mt76u_skb_dma_info routine in mt76x02-usb module and rename it in mt76x02u_skb_dma_info. Moreover move mt76x02u_set_txinfo in mt76x02_usb_core.c. This is a preliminary patch to move MT_TXD_INFO, MT_MCU_MSG and MT_RX_FCE_INFO defs in mt76x02-lib module since other chipsets (e.g. mt7603) use different dma definitions Acked-by: Stanislaw Gruszka <sgruszka@redhat.com> Signed-off-by: Lorenzo Bianconi <lorenzo.bianconi@redhat.com> Signed-off-by: Felix Fietkau <nbd@nbd.name>
