git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound Pull sound updates from Takashi Iwai: "Lots of changes (slightly more code increase than usual) at this time, while most of code changes are ASoC driver-specific. Here are some highlights: Core: - The new auxiliary bus implementation for Intel DSP, which will be used by other drivers as well - Lots of ASoC core cleanups and refactoring - UBSAN and KCSAN fixes in rawmidi, sequencer and a few others - Compress-offload API enhancement for the pause during draining HD- and USB-audio: - Enhancements of the USB-audio implicit feedback support, including better full-duplex operations - Continued CA0132 improvements and fixes - A few new quirk entries, HDMI audio fixes ASoC: - Support for boot time selection of Intel DSP firmware, which should help distros/users testing new stuff more easily; the kconfig was moved to boot time option, too - Some basic DPCM support in audio graph card - Removal of old pre-DT Freescale drivers - Support for Allwinner H6 I2S, Analog Devices ADAU1372, Intel Alderlake-S, GMediatek MT8192, NXP i.MX HDMI and XCVR, Realtek RT715, Qualcomm SM8250 and simple GPIO based muxes" * tag 'sound-5.11-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound: (445 commits) ALSA: pcm: oss: Fix potential out-of-bounds shift ALSA: usb-audio: Fix potential out-of-bounds shift ALSA: hda/ca0132 - Add ZxR surround DAC setup.

2020-12-15zram: break the strict dependency from lzoRui Salvaterra3-2/+44
From the beginning, the zram block device always enabled CRYPTO_LZO, since lzo-rle is hardcoded as the fallback compression algorithm. As a consequence, on systems where another compression algorithm is chosen (e.g. CRYPTO_ZSTD), the lzo kernel module becomes unused, while still having to be built/loaded. This patch removes the hardcoded lzo-rle dependency and allows the user to select the default compression algorithm for zram at build time. The previous behaviour is kept, as the default algorithm is still lzo-rle.

2020-12-15zram: add stat to gather incompressible pages since zram set upMinchan Kim2-2/+5
Currently, zram supports the stat via /sys/block/zram/mm_stat to represent how many of incompressible pages are stored at the moment but it couldn't show how many times incompressible pages were wrote down since zram set up. It's also good indication to see how zram is effective in the system.

There is demand to writeback specific process pages to backing store instead of all idles pages in the system due to storage wear out concerns and to launching latency of apps which are most of the time idle but are critical for resume latency. This patch extends the writeback knob to support a specific page writeback.

2020-12-15mm, page_poison: remove CONFIG_PAGE_POISONING_NO_SANITYVlastimil Babka1-3/+1
CONFIG_PAGE_POISONING_NO_SANITY skips the check on page alloc whether the poison pattern was corrupted, suggesting a use-after-free. The motivation to introduce it in commit 8823b1dbc05f ("mm/page_poison.c: enable PAGE_POISONING as a separate option") was to simply sanitize freed pages, optimally together with CONFIG_PAGE_POISONING_ZERO. These days we have an init_on_free=1 boot option, which makes this use case of page poisoning redundant. For sanitizing, writing zeroes is sufficient, there is pretty much no benefit from writing the 0xAA poison pattern to freed pages, without checking it back on alloc. Thus, remove this option and suggest init_on_free instead in the main config's help.

2020-12-15mm, page_poison: use static key more efficientlyVlastimil Babka1-1/+1
Commit 11c9c7edae06 ("mm/page_poison.c: replace bool variable with static key") changed page_poisoning_enabled() to a static key check. However, the function is not inlined, so each check still involves a function call with overhead not eliminated when page poisoning is disabled. Analogically to how debug_pagealloc is handled, this patch converts page_poisoning_enabled() back to boolean check, and introduces page_poisoning_enabled_static() for fast paths. Both functions are inlined. The function kernel_poison_pages() is also called unconditionally and does the static key check inside. Remove it from there and put it to callers. Also split it to two functions kernel_poison_pages() and kernel_unpoison_pages() instead of the confusing bool parameter. Also optimize the check that enables page poisoning instead of debug_pagealloc for architectures without proper debug_pagealloc support. Move the check to init_mem_debugging_and_hardening() to enable a single static key instead of having two static branches in page_poisoning_enabled_static().

Building lkdtm with KASAN and Clang 11 or later results in the following error when attempting to load the module: kernel tried to execute NX-protected page - exploit attempt?

When Clang 11 adds a module constructor to rodata.o, it is also added to .rodata: any attempt to call it on initialization results in the above error. Therefore, disable KASAN instrumentation for rodata.o.

2020-12-15mm: memcontrol: account pagetables per nodeShakeel Butt1-1/+1
For many workloads, pagetable consumption is significant and it makes sense to expose it in the memory.stat for the memory cgroups. However at the moment, the pagetables are accounted per-zone. Converting them to per-node and using the right interface will correctly account for the memory cgroups as well.

2020-12-15mm/gup: prevent gup_fast from racing with COW during forkJason Gunthorpe1-0/+1
Since commit 70e806e4e645 ("mm: Do early cow for pinned pages during fork() for ptes") pages under a FOLL_PIN will not be write protected during COW for fork. This means that pages returned from pin_user_pages(FOLL_WRITE) should not become write protected while the pin is active. However, there is a small race where get_user_pages_fast(FOLL_PIN) can establish a FOLL_PIN at the same time copy_present_page() is write protecting it: CPU 0 CPU 1 get_user_pages_fast() internal_get_user_pages_fast() copy_page_range() pte_alloc_map_lock() copy_present_page() atomic_read(has_pinned) == 0 page_maybe_dma_pinned() == false atomic_set(has_pinned, 1); gup_pgd_range() gup_pte_range() pte_t pte = gup_get_pte(ptep) pte_access_permitted(pte) try_grab_compound_head() pte = pte_wrprotect(pte) set_pte_at(); pte_unmap_unlock() // GUP now returns with a write protected page The first attempt to resolve this by using the write protect caused problems (and was missing a barrrier), see commit f3c64eda3e50 ("mm: avoid early COW write protect games during fork()") Instead wrap copy_p4d_range() with the write side of a seqcount and check the read side around gup_pgd_range(). If there is a collision then get_user_pages_fast() fails and falls back to slow GUP. Slow GUP is safe against this race because copy_page_range() is only called while holding the exclusive side of the mmap_lock on the src mm_struct.

In the discussion about preempt count consistency across kernel configurations: https://lore.kernel.org/r/[email protected]/ it was concluded that the usage of in_interrupt() and related context checks should be removed from non-core code. Both BUG_ON()s in ide-probe.c were introduced in commit 4015c949fb465 ("[PATCH] update ide core") when ide_unregister() was extended with semaphore based locking. Both checks won't complain about disabled preemption which is also wrong. The might_sleep() in today's mutex_lock() will complain about the missuses. Remove the BUG_ON() statements.
