2023-03-09ASoC: hdmi-codec: only startup/shutdown on supported streamsEmil Abildgaard Svendsen
Currently only one stream is supported. This isn't usally a problem until you have a multi codec audio card. Because the audio card will run startup and shutdown on both capture and playback streams. So if your hdmi-codec only support either playback or capture. Then ALSA can't open for playback and capture. This patch will ignore if startup and shutdown are called with a non supported stream. Thus, allowing an audio card like this: +-+ cpu1 <--@-| |-> codec1 (HDMI-CODEC) | |<- codec2 (NOT HDMI-CODEC) +-+ Signed-off-by: Emil Svendsen <emas@bang-olufsen.dk> Link: https://lore.kernel.org/r/20230309065432.4150700-2-emas@bang-olufsen.dk Signed-off-by: Mark Brown <broonie@kernel.org>

Now that the same hardware that the r8188eu driver supported is supported by the real wireless driver rtl8xxxu, the r8188eu driver can be deleted. Also the rtl8xxxu driver supports way more devices, and is a fraction of the overall size, making this a much better overall solution.

2023-03-08af_unix: fix struct pid leaks in OOB supportEric Dumazet
syzbot reported struct pid leak [1]. Issue is that queue_oob() calls maybe_add_creds() which potentially holds a reference on a pid. But skb->destructor is not set (either directly or by calling unix_scm_to_skb()) This means that subsequent kfree_skb() or consume_skb() would leak this reference.

2023-03-08net: dsa: mt7530: permit port 5 to work without port 6 on MT7621 SoCVladimir Oltean
The MT7530 switch from the MT7621 SoC has 2 ports which can be set up as internal: port 5 and 6. Arınç reports that the GMAC1 attached to port 5 receives corrupted frames, unless port 6 (attached to GMAC0) has been brought up by the driver. This is true regardless of whether port 5 is used as a user port or as a CPU port (carrying DSA tags). Offline debugging (blind for me) which began in the linked thread showed experimentally that the configuration done by the driver for port 6 contains a step which is needed by port 5 as well - the write to CORE_GSWPLL_GRP2 (note that I've no idea as to what it does, apart from the comment "Set core clock into 500Mhz"). Prints put by Arınç show that the reset value of CORE_GSWPLL_GRP2 is RG_GSWPLL_POSDIV_500M(1) | RG_GSWPLL_FBKDIV_500M(40) (0x128), both on the MCM MT7530 from the MT7621 SoC, as well as on the standalone MT7530 from MT7623NI Bananapi BPI-R2. Apparently, port 5 on the standalone MT7530 can work under both values of the register, while on the MT7621 SoC it cannot. The call path that triggers the register write is: mt753x_phylink_mac_config() for port 6 -> mt753x_pad_setup() -> mt7530_pad_clk_setup() so this fully explains the behavior noticed by Arınç, that bringing port 6 up is necessary. The simplest fix for the problem is to extract the register writes which are needed for both port 5 and 6 into a common mt7530_pll_setup() function, which is called at mt7530_setup() time, immediately after switch reset. We can argue that this mirrors the code layout introduced in mt7531_setup() by commit 42bc4fafe359 ("net: mt7531: only do PLL once after the reset"), in that the PLL setup has the exact same positioning, and further work to consolidate the separate setup() functions is not hindered. Testing confirms that: - the slight reordering of writes to MT7530_P6ECR and to CORE_GSWPLL_GRP1 / CORE_GSWPLL_GRP2 introduced by this change does not appear to cause problems for the operation of port 6 on MT7621 and on MT7623 (where port 5 also always worked) - packets sent through port 5 are not corrupted anymore, regardless of whether port 6 is enabled by phylink or not (or even present in the device tree) My algorithm for determining the Fixes: tag is as follows. Testing shows that some logic from mt7530_pad_clk_setup() is needed even for port 5. Prior to commit ca366d6c889b ("net: dsa: mt7530: Convert to PHYLINK API"), a call did exist for all phy_is_pseudo_fixed_link() ports - so port 5 included. That commit replaced it with a temporary "Port 5 is not supported!" comment, and the following commit 38f790a80560 ("net: dsa: mt7530: Add support for port 5") replaced that comment with a configuration procedure in mt7530_setup_port5() which was insufficient for port 5 to work. I'm laying the blame on the patch that claimed support for port 5, although one would have also needed the change from commit c3b8e07909db ("net: dsa: mt7530: setup core clock even in TRGMII mode") for the write to be performed completely independently from port 6's configuration. Thanks go to Arınç for describing the problem, for debugging and for testing.

2023-03-08x86/resctl: fix scheduler confusion with 'current'Linus Torvalds
The implementation of 'current' on x86 is very intentionally special: it is a very common thing to look up, and it uses 'this_cpu_read_stable()' to get the current thread pointer efficiently from per-cpu storage. And the keyword in there is 'stable': the current thread pointer never changes as far as a single thread is concerned. Even if when a thread is preempted, or moved to another CPU, or even across an explicit call 'schedule()' that thread will still have the same value for 'current'. It is, after all, the kernel base pointer to thread-local storage. That's why it's stable to begin with, but it's also why it's important enough that we have that special 'this_cpu_read_stable()' access for it. So this is all done very intentionally to allow the compiler to treat 'current' as a value that never visibly changes, so that the compiler can do CSE and combine multiple different 'current' accesses into one. However, there is obviously one very special situation when the currently running thread does actually change: inside the scheduler itself. So the scheduler code paths are special, and do not have a 'current' thread at all. Instead there are _two_ threads: the previous and the next thread - typically called 'prev' and 'next' (or prev_p/next_p) internally. So this is all actually quite straightforward and simple, and not all that complicated. Except for when you then have special code that is run in scheduler context, that code then has to be aware that 'current' isn't really a valid thing. Did you mean 'prev'? Did you mean 'next'? In fact, even if then look at the code, and you use 'current' after the new value has been assigned to the percpu variable, we have explicitly told the compiler that 'current' is magical and always stable. So the compiler is quite free to use an older (or newer) value of 'current', and the actual assignment to the percpu storage is not relevant even if it might look that way. Which is exactly what happened in the resctl code, that blithely used 'current' in '__resctrl_sched_in()' when it really wanted the new process state (as implied by the name: we're scheduling 'into' that new resctl state). And clang would end up just using the old thread pointer value at least in some configurations. This could have happened with gcc too, and purely depends on random compiler details. Clang just seems to have been more aggressive about moving the read of the per-cpu current_task pointer around. The fix is trivial: just make the resctl code adhere to the scheduler rules of using the prev/next thread pointer explicitly, instead of using 'current' in a situation where it just wasn't valid. That same code is then also used outside of the scheduler context (when a thread resctl state is explicitly changed), and then we will just pass in 'current' as that pointer, of course. There is no ambiguity in that case. The fix may be trivial, but noticing and figuring out what went wrong was not. The credit for that goes to Stephane Eranian.

Note that the second call was already somewhat fixed by commenting out WLAN_CAPABILITY_ESS and passing in 0 instead. This was still not entirely correct though since that would limit returned BSS-es to ESS type BSS-es with privacy on.

2023-03-08staging: rtl8723bs: Fix key-store index handlingHans de Goede
There are 2 issues with the key-store index handling 1. The non WEP key stores can store keys with indexes 0 - BIP_MAX_KEYID, this means that they should be an array with BIP_MAX_KEYID + 1 entries. But some of the arrays where just BIP_MAX_KEYID entries big. While one other array was hardcoded to a size of 6 entries, instead of using the BIP_MAX_KEYID define. 2. The rtw_cfg80211_set_encryption() and wpa_set_encryption() functions index check where checking that the passed in key-index would fit inside both the WEP key store (which only has 4 entries) as well as in the non WEP key stores. This breaks any attempts to set non WEP keys with index 4 or 5. Issue 2. specifically breaks wifi connection with some access points which advertise PMF support. Without this fix connecting to these access points fails with the following wpa_supplicant messages: nl80211: kernel reports: key addition failed wlan0: WPA: Failed to configure IGTK to the driver wlan0: RSN: Failed to configure IGTK wlan0: CTRL-EVENT-DISCONNECTED bssid=... reason=1 locally_generated=1 Fix 1. by using the right size for the key-stores. After this 2. can safely be fixed by checking the right max-index value depending on the used algorithm, fixing wifi not working with some PMF capable APs.

2023-03-08io_uring/io-wq: stop setting PF_NO_SETAFFINITY on io-wq workersJens Axboe
Every now and then reports come in that are puzzled on why changing affinity on the io-wq workers fails with EINVAL. This happens because they set PF_NO_SETAFFINITY as part of their creation, as io-wq organizes workers into groups based on what CPU they are running on. However, this is purely an optimization and not a functional requirement. We can allow setting affinity, and just lazily update our worker to wqe mappings. If a given io-wq thread times out, it normally exits if there's no more work to do. The exception is if it's the last worker available. For the timeout case, check the affinity of the worker against group mask and exit even if it's the last worker. New workers should be created with the right mask and in the right location.

Port is allocated by sas_port_alloc_num() and rphy is allocated by either sas_end_device_alloc() or sas_expander_alloc(), all of which may return NULL. So we need to check the rphy to avoid possible NULL pointer access. If sas_rphy_add() returned with failure, rphy is set to NULL. We would access the rphy in the following lines which would also result NULL pointer access.
