2022-09-02wifi: rtw89: pci: fix interrupt stuck after leaving low power modePing-Ke Shih
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.

2022-09-02wifi: rtw89: early recognize FW feature to decide if chanctxZong-Zhe Yang
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.

2022-09-02wifi: rtw89: declare support for mac80211 chanctx ops by chipZong-Zhe Yang
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.

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.

2022-09-02wifi: rtw89: initialize entity and configure default chandefZong-Zhe Yang
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.

2022-09-02wifi: rtw89: concentrate chandef setting to stack callbackZong-Zhe Yang
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, 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.

2022-09-02wifi: rtw89: create rtw89_chan centrally to avoid breakageZong-Zhe Yang
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.

2022-09-02wifi: rtw89: re-arrange channel related stuffs under HALZong-Zhe Yang
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.

2022-09-02wifi: rtw89: introduce rtw89_chan for channel stuffsZong-Zhe Yang
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.)

2022-09-02wifi: rtw89: rewrite decision on channel by entity stateZong-Zhe Yang
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.

2022-09-01ipv6: tcp: send consistent autoflowlabel in SYN_RECV stateEric Dumazet
This is a followup of commit c67b85558ff2 ("ipv6: tcp: send consistent autoflowlabel in TIME_WAIT state"), but for SYN_RECV state. In some cases, TCP sends a challenge ACK on behalf of a SYN_RECV request. WHen this happens, we want to use the flow label that was used when the prior SYNACK packet was sent, instead of another one. After his patch, following packetdrill passes: 0 socket(..., SOCK_STREAM, IPPROTO_TCP) = 3 +0 setsockopt(3, SOL_SOCKET, SO_REUSEADDR, [1], 4) = 0 +0 bind(3, ..., ...) = 0 +0 listen(3, 1) = 0 +.2 < S 0:0(0) win 32792 <mss 1000,sackOK,nop,nop,nop,wscale 7> +0 > (flowlabel 0x11) S. 0:0(0) ack 1 <...> // Test if a challenge ack is properly sent (same flowlabel than prior SYNACK) +.01 < . 4000000000:4000000000(0) ack 1 win 320 +0 > (flowlabel 0x11) . 1:1(0) ack 1 Signed-off-by: Eric Dumazet <edumazet@google.com> Link: https://lore.kernel.org/r/20220831203729.458000-1-eric.dumazet@gmail.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>
