This does a "chunk_len - 4" subtraction later when it calls: ret = wfx_hif_configuration(wdev, buf + 4, chunk_len - 4); so check for "chunk_len" is less than 4. Fixes: dcbecb49 ("staging: wfx: allow new PDS format") Signed-off-by:

There some bounds checking to ensure that "map_addr" is not out of bounds before the start of the loop. But the checking needs to be done as we iterate through the loop because "map_addr" gets larger as we iterate. Fixes: 26f1fad2 ("New driver: rtl8xxxu (mac80211)") Signed-off-by:

We turn off interrupt in ISR, and re-enable interrupt in threadfn or napi_poll according to the mode it stays. If we are turning off interrupt, rtwpci->running flag is unset and interrupt handler stop processing even if it was called, so disallow to re-enable interrupt in this situation. Or, wifi chip doesn't trigger interrupt events anymore because interrupt status (ISR) isn't clear by interrupt handler anymore. Fixes: c83dcd05 ("rtw89: pci: add a separate interrupt handler for low power mode") Signed-off-by:

When starting to send heavy traffic in low power mode, driver will call multiple tx wake notify to wake firmware within a short time. In this situation, firmware may miss power mode change request from driver and leads to status error. So we change driver to call power_mode_change at most three times to make sure firmware could get the request. Signed-off-by:

Sometimes, BB might encounter RX problem on OFDM 6M. It's not quite easy to happen, but if it happens, we will keep getting stuck on RX. And, since we cannot properly receive layer 2 ACK, it also casues TX problem, e.g. constantly retrying TX. Eventually, after some time, we would get disconnected due to abnormal behavior. Update break setting and phy status parsing time to make BB get out of stuck state faster. Signed-off-by:

In current flow, FW is asynchronously loaded after alloc_hw(). It defers the decision on FW feature map. It makes things difficult for us to decide whether to hook chanctx ops, which should be decided while alloc_hw() is calling. Still, asynchronous gets its advantages. So, we want to resolve this without dropping them. Based on multi-FW flag, RTW89_MFW_SIG, we can determine runtime FW is multi-FW (MFW) or single FW (SFW). Both of them have a quite small chunk for header at the head. The difference is that MFW doesn't describe version code in its header while SFW does. So, we plan to extend MFW header for version code. After that, in both cases, we can determine FW feature map by just FW header. And, according to the map, we can decide chanctx. So, we call request_partial_firmware_into_buf() to request a quite small chunk before alloc_hw() to get a early FW feature map without affecting things much and only use early map to decide whether to hook chanctx ops. It means that if non-extended MFW is used at runtime, driver just acts without chanctx as before. If extended MFW or SFW, which supports required FW features, is used at runtime, driver can hook chanctx ops to mac80211 if chip has configured support_chanctx_num > 0. Besides, key point for now to support single one chanctx is whether HW scan is supported at runtime. So, we configure all chip's support_chanctx_num to 1, and check if HW scan is supported at runtime via early FW feature map. Signed-off-by:

Some HW features are required if we hook chanctx ops to mac80211. With it, mac80211 would expect the HW-supported variant ops exists on some behavior, e.g. HW scan. But, HW features may depend on chip's FW or its development. Besides, how many chanctx can be supported also depends on chip design. We can neither decide whether to generally support chanctx ops nor how many chanctx can be supported. So, support_chanctx_num is added under chip info to deal with this by chip. For now, all chip configure support_chanctx_num as 0. We haven't really hook chanctx ops yet. So, chip can run without mac80211 chanctx as before. Signed-off-by:

Support mac80211 chanctx series ops. Still, currently support single channel. Based on this premise, things should be similar to before. So, we haven't dealt with relationship between vif and chanctx in depth. Instead, we leave both ::assign_vif() and ::unassign_vif() as noops for now. Signed-off-by:

After supporting more than one channel, we need entity mode to decide how to set current channel(s) on the sub-entities. This decision may happen on set_channel() and rtw89_core_set_chip_txpwr(). For now, we support single one channel and use only first HW entry, i.e. RTW89_SUB_ENTITY_0, RTW89_MAC_0, RTW89_PHY_0. Without something unexpected, the entity mode should always be RTW89_ENT_MODE_SCC after recalcated, where SCC means single channel concurrency. So, an assert is added in set_channel() and rtw89_core_set_chip_txpwr(). Signed-off-by:

While idle, we need a default chandef to set channel for things, such as scan. Before support of mac80211 chanctx, mac80211 would configure a default one on ieee80211_hw::conf::chandef. And we just queried it whenever we did set channel. However, after support of mac80211 chanctx, the flow won't work like before. Besides, we don't now query chandef from ieee80211_hw::conf::chandef either. So, similar to mac80211 without using chanctx, we configure the default chandef with ieee80211_channel of index 0 in 2GHz. Although we have not added the support of mac80211 chanctx here, this configuration should be compatible before that. So, we commit this ahead. Signed-off-by:

Originally, we didn't support mac80211 chanctx, so it's expected that ieee80211_hw::conf::chandef would be filled by mac80211. And then, we could just query it whenever we need the current chandef. However, we are planing to support mac80211 chanctx. After that, the above assumption would be broken. So, we adjust a bit ahead to reduce future works about mac80211 chanctx. After this, we don't query ieee80211_hw::conf::chandef directly, and we add a map, entity_map, to HAL to indicate which chandef came from stack. And it will later be used to recalcate entity mode.
