2022-09-29docs/doc-guide: Add documentation on SPHINX_IMGMATHAkira Yokosawa
Now that building html docs with math expressions does not need texlive packages, remove the note on the requirement in the "Sphinx Install" section. Instead, add sections of "Math Expressions in HTML" and "Choice of Math Renderer". Describe the effect of setting SPHINX_IMGMATH in the latter section.

2022-09-29Merge branch 'fp' into docs-mwJonathan Corbet
The top-level index.rst file is the entry point for the kernel's documentation, especially for readers of the HTML output. It is currently a mess containing everything we thought to throw in there. Firefox says it would require 26 pages of paper to print it. That is not a user-friendly introduction. This series aims to improve our documentation entry point with a focus on rewriting index.rst. The result is, IMO, simpler and more approachable. For anybody who wants to see the rendered results without building the docs, have a look at: https://static.lwn.net/kerneldoc/ This time around I've rendered the pages using the "Read The Docs" theme, since that's what everybody will get by default. That theme ignores the directives regarding the left column, so the results are not as good there. I have a series proposing a default-theme change in the works, but that's a separate topic. This is only a beginning; I think this kind of organizational effort has to be pushed down into the lower layers of the docs tree itself. But one has to start somewhere.

2022-09-29Merge branch 'bpf: Remove recursion check for struct_ops prog'Alexei Starovoitov
Martin KaFai Lau says: ==================== From: Martin KaFai Lau <martin.lau@kernel.org> The struct_ops is sharing the tracing-trampoline's enter/exit function which tracks prog->active to avoid recursion. It turns out the struct_ops bpf prog will hit this prog->active and unnecessarily skipped running the struct_ops prog. eg. The '.ssthresh' may run in_task() and then interrupted by softirq that runs the same '.ssthresh'. The kernel does not call the tcp-cc's ops in a recursive way, so this set is to remove the recursion check for struct_ops prog. v3: - Clear the bpf_chg_cc_inprogress from the newly cloned tcp_sock in tcp_create_openreq_child() because the listen sk can be cloned without lock being held. (Eric Dumazet) v2: - v1 [0] turned into a long discussion on a few cases and also whether it needs to follow the bpf_run_ctx chain if there is tracing bpf_run_ctx (kprobe/trace/trampoline) running in between. It is a good signal that it is not obvious enough to reason about it and needs a tradeoff for a more straight forward approach. This revision uses one bit out of an existing 1 byte hole in the tcp_sock. It is in Patch 4.

2022-09-29bpf: tcp: Stop bpf_setsockopt(TCP_CONGESTION) in init ops to recur itselfMartin KaFai Lau
When a bad bpf prog '.init' calls bpf_setsockopt(TCP_CONGESTION, "itself"), it will trigger this loop: .init => bpf_setsockopt(tcp_cc) => .init => bpf_setsockopt(tcp_cc) ... ... => .init => bpf_setsockopt(tcp_cc). It was prevented by the prog->active counter before but the prog->active detection cannot be used in struct_ops as explained in the earlier patch of the set. In this patch, the second bpf_setsockopt(tcp_cc) is not allowed in order to break the loop. This is done by using a bit of an existing 1 byte hole in tcp_sock to check if there is on-going bpf_setsockopt(TCP_CONGESTION) in this tcp_sock. Note that this essentially limits only the first '.init' can call bpf_setsockopt(TCP_CONGESTION) to pick a fallback cc (eg. peer does not support ECN) and the second '.init' cannot fallback to another cc. This applies even the second bpf_setsockopt(TCP_CONGESTION) will not cause a loop.

2022-09-29bpf: Move the "cdg" tcp-cc check to the common sol_tcp_sockopt()Martin KaFai Lau
The check on the tcp-cc, "cdg", is done in the bpf_sk_setsockopt which is used by the bpf_tcp_ca, bpf_lsm, cg_sockopt, and tcp_iter hooks. However, it is not done for cg sock_ddr, cg sockops, and some of the bpf_lsm_cgroup hooks. The tcp-cc "cdg" should have very limited usage. This patch is to move the "cdg" check to the common sol_tcp_sockopt() so that all hooks have a consistent behavior. The motivation to make this check consistent now is because the latter patch will refactor the bpf_setsockopt(TCP_CONGESTION) into another function, so it is better to take this chance to refactor this piece also.

2022-09-29bpf: Add __bpf_prog_{enter,exit}_struct_ops for struct_ops trampolineMartin KaFai Lau
The struct_ops prog is to allow using bpf to implement the functions in a struct (eg. kernel module). The current usage is to implement the tcp_congestion. The kernel does not call the tcp-cc's ops (ie. the bpf prog) in a recursive way. The struct_ops is sharing the tracing-trampoline's enter/exit function which tracks prog->active to avoid recursion. It is needed for tracing prog. However, it turns out the struct_ops bpf prog will hit this prog->active and unnecessarily skipped running the struct_ops prog. eg. The '.ssthresh' may run in_task() and then interrupted by softirq that runs the same '.ssthresh'. Skip running the '.ssthresh' will end up returning random value to the caller. The patch adds __bpf_prog_{enter,exit}_struct_ops for the struct_ops trampoline. They do not track the prog->active to detect recursion. One exception is when the tcp_congestion's '.init' ops is doing bpf_setsockopt(TCP_CONGESTION) and then recurs to the same '.init' ops. This will be addressed in the following patches.

2022-09-29drm/amd/display: Prevent OTG shutdown during PSR SULeo Li
[Why] Enabling Z10 optimizations allows DMUB to disable the OTG during PSR link-off. This theoretically saves power by putting more of the display hardware to sleep. However, we observe that with PSR SU, it causes visual artifacts, higher power usage, and potential system hang. This is partly due to an odd behavior with the VStartup interrupt used to signal DRM vblank events. If the OTG is toggled on/off during a PSR link on/off cycle, the vstartup interrupt fires twice in quick succession. This generates incorrectly timed vblank events. Additionally, it can cause cursor updates to generate visual artifacts. Note that this is not observed with PSR1 since PSR is fully disabled when there are vblank event requestors. Cursor updates are also artifact-free, likely because there are no selectively-updated (SU) frames that can generate artifacts. [How] A potential solution is to disable z10 idle optimizations only when fast updates (flips & cursor updates) are committed. A mechanism to do so would require some thoughtful design. Let's just disable idle optimizations for PSR2 for now.

2022-09-29wifi: rtl8xxxu: Fix AIFS written to REG_EDCA_*_PARAMBitterblue Smith
ieee80211_tx_queue_params.aifs is not supposed to be written directly to the REG_EDCA_*_PARAM registers. Instead process it like the vendor drivers do. It's kinda hacky but it works. This change boosts the download speed and makes it more stable. Tested with RTL8188FU but all the other supported chips should also benefit.

2022-09-29wifi: rtl8xxxu: gen2: Enable 40 MHz channel widthBitterblue Smith
The module parameter ht40_2g was supposed to enable 40 MHz operation, but it didn't. Tell the firmware about the channel width when updating the rate mask. This makes it work with my gen 2 chip RTL8188FU. I'm not sure if anything needs to be done for the gen 1 chips, if 40 MHz channel width already works or not. They update the rate mask with a different structure which doesn't have a field for the channel width. Also set the channel width correctly for sta_statistics.
