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.

For future support on multiple channels by multiple sub-entities, we need to manage parameters of each channel instance like rtw89_chan, rtw89_mac_idx, rtw89_phy_idx. So, we adjust related channel callback functions and centrally conrtol these parameters in set_channel(). Signed-off-by:

For future support on multiple channels, there will be settings of multiple sub-entities that we need to control. We don't want such settings to be scattered all over the place. So, we centrally manage controls of rtw89_phy_idx for RFK in set_channel(). Signed-off-by:

For future support on multiple channels, it would be disturbing if we still allow scattered leaf functions of TX power to query and manage channel related control by themselves. So, query rtw89_chan only on top functions. Then, pass it via functions to make sure that the values coming from the same struct rtw89_chan. Besides, fix rtw8852a_set_txpwr_offset() from rtw8852a_set_txpwr_ctrl() to rtw8852a_set_txpwr(). TX power offset should consider current band, so move it to chip_ops::set_txpwr() which will be called every time that channel is set. Signed-off-by:

Sometimes we need to write current rtw89_chan outside set_channel(), e.g. during HW scan, we adjust it to align FW process through C2H. However, we don't have full parameters to fill entire rtw89_chan. And it will breakage if we update only part of current rtw89_chan. That is what we don't want to see because most flows throughout driver treat rtw89_chan as a whole. So, we divide struct rtw89_chan to basic part and derived part. The basic part contains the parameters which we are always able to know. And the derived part will be calculated by the basic part. Then, a central function, rtw89_chan_create(), is added to deal with this. Signed-off-by:

We are planning to support mac80211 chanctx. To reduce future works, the driver architecture is adjusted first to isolate related things. According to chip, our HW may have multiple sub-entities to support multiple mac80211 chanctx. Struct rtw89_chan has been introduced for things about channel/band/subband/... Now introduce struct rtw89_chan_rcd to record difference after assigning new one of struct rtw89_chan. We will implement and support chanctx with single channel first, i.e. only use entry in RTW89_SUB_ENTITY_0, before handling dual channels. Our hierarchy in planning will become as the following. DEV -> HAL ---> entity (manage status across sub-entities) -----> sub-entity[*] (support mac80211 chanctx) where each sub-entity contains one struct rtw89_chan. Signed-off-by:

Introduce struct rtw89_chan ahead to encapsulate stuffs from struct rtw89_channel_params. These stuffs have a clone in HAL and are used throughout driver. After multiple channels support, it's expected that each channel instance has a configuration of them. So, we refine them with struct rtw89_chan by precise type first, and will re-arrange HAL by struct rtw89_chan in the following as well. (No logic has changed.) Signed-off-by:

We need to invoke the callback of the changed band at the first set_channel() after every power-off. Originally, we forced the channel to be 0 when doing power-off, and then determined things by comparing channel with 0. However, deciding on such things by channel might be confusing. It's also confusing to use this kind of decision when we consider multiple channels in the follow-up patches. So, another flag, entity_active, is added ahead to HAL to deal with this. Besides, we also need to check if entity is active when we set TX power. Signed-off-by:

syzbot is reporting uninit value at ath9k_htc_rx_msg() [1], for ioctl(USB_RAW_IOCTL_EP_WRITE) can call ath9k_hif_usb_rx_stream() with pkt_len = 0 but ath9k_hif_usb_rx_stream() uses __dev_alloc_skb(pkt_len + 32, GFP_ATOMIC) based on an assumption that pkt_len is valid. As a result, ath9k_hif_usb_rx_stream() allocates skb with uninitialized memory and ath9k_htc_rx_msg() is reading from uninitialized memory. Since bytes accessed by ath9k_htc_rx_msg() is not known until ath9k_htc_rx_msg() is called, it would be difficult to check minimal valid pkt_len at "if (pkt_len > 2 * MAX_RX_BUF_SIZE) {" line in ath9k_hif_usb_rx_stream(). We have two choices. One is to workaround by adding __GFP_ZERO so that ath9k_htc_rx_msg() sees 0 if pkt_len is invalid. The other is to let ath9k_htc_rx_msg() validate pkt_len before accessing. This patch chose the latter. Note that I'm not sure threshold condition is correct, for I can't find details on possible packet length used by this protocol.

The Lenovo OneLink+ Dock contains an RTL8153 controller that behaves as a broken CDC device by default. Add the custom Lenovo PID to the r8152 driver to support it properly. Also, systems compatible with this dock provide a BIOS option to enable MAC address passthrough (as per Lenovo document "ThinkPad Docking Solutions 2017"). Add the custom PID to the MAC passthrough list too. Tested on a ThinkPad 13 1st gen with the expected results: passthrough disabled: Invalid header when reading pass-thru MAC addr passthrough enabled: Using pass-thru MAC addr XX:XX:XX:XX:XX:XX Signed-off-by:

Maksym Glubokiy says: ==================== net: prestera: matchall features This patch series extracts matchall rules management out of SPAN API implementation and adds 2 features on top of that: - support for egress traffic (mirred egress action) - proper rule priorities management between matchall and flower ==================== Signed-off-by: -
Maksym Glubokiy authored
matchall rules can be added only to chain 0 and their priorities have limitations: - new matchall ingress rule's priority must be higher (lower value) than any existing flower rule; - new matchall egress rule's priority must be lower (higher value) than any existing flower rule. The opposite works for flower rule adding: - new flower ingress rule's priority must be lower (higher value) than any existing matchall rule; - new flower egress rule's priority must be higher (lower value) than any existing matchall rule. This is a hardware limitation and thus must be properly handled in driver by reporting errors to the user when newly added rule has such a priority that cannot be installed into the hardware. To achieve this, the driver must maintain both min/max matchall priorities for every flower block when user adds/deletes a matchall rule, as well as both min/max flower priorities for chain 0 for every adding/deletion of flower rules for chain 0.

This commit adds more clarity to handling of TC_CLSMATCHALL_REPLACE and TC_CLSMATCHALL_DESTROY events by calling newly added *_mall_*() handlers instead of directly calling SPAN API. This also extracts matchall rules management out of SPAN API since SPAN is a hardware module which is used to implement 'matchall egress mirred' action only. Signed-off-by:
