2023-05-18ALSA: emu10k1: enable bit-exact playback, part 4: send amountsOswald Buddenhagen1-0/+2
On Audigy, the send amounts are merely targets, presumably to avoid sound distortion due to sudden changes, which the EMU8K docu explicitly warns about. However, that "soft-start" would prevent bit-for-bit reproduction, so we now force the current send amounts to their final values at PCM playback init. One might want to do that for the MIDI synthesizer as well, though it seems mostly pointless due to the attack phase each note has anyway.

2023-05-18fbdev: Move framebuffer I/O helpers into <asm/fb.h>Thomas Zimmermann2-53/+102
Implement framebuffer I/O helpers, such as fb_read*() and fb_write*(), in the architecture's <asm/fb.h> header file or the generic one. The common case has been the use of regular I/O functions, such as __raw_readb() or memset_io(). A few architectures used plain system- memory reads and writes. Sparc used helpers for its SBus. The architectures that used special cases provide the same code in their __raw_*() I/O helpers. So the patch replaces this code with the __raw_*() functions and moves it to <asm-generic/fb.h> for all architectures. v8: * remove garbage after commit-message tags v6: * fix fb_readq()/fb_writeq() on 64-bit mips (kernel test robot) v5: * include <linux/io.h> in <asm-generic/fb>; fix s390 build v4: * ia64, loongarch, sparc64: add fb_mem*() to arch headers to keep current semantics (Arnd) v3: * implement all architectures with generic helpers * support reordering and native byte order (Geert, Arnd) Signed-off-by: Thomas Zimmermann <[email protected]> Tested-by: Sui Jingfeng <[email protected]> Reviewed-by: Arnd Bergmann <[email protected]> Link: https://patchwork.freedesktop.org/patch/msgid/[email protected]

2023-05-17mm: shrinkers: fix race condition on debugfs cleanupJoan Bruguera Micó1-2/+11
When something registers and unregisters many shrinkers, such as: for x in $(seq 10000); do unshare -Ui true; done Sometimes the following error is printed to the kernel log: debugfs: Directory '...' with parent 'shrinker' already present! This occurs since commit badc28d4924b ("mm: shrinkers: fix deadlock in shrinker debugfs") / v6.2: Since the call to `debugfs_remove_recursive` was moved outside the `shrinker_rwsem`/`shrinker_mutex` lock, but the call to `ida_free` stayed inside, a newly registered shrinker can be re-assigned that ID and attempt to create the debugfs directory before the directory from the previous shrinker has been removed. The locking changes in commit f95bdb700bc6 ("mm: vmscan: make global slab shrink lockless") made the race condition more likely, though it existed before then. Commit badc28d4924b ("mm: shrinkers: fix deadlock in shrinker debugfs") could be reverted since the issue is addressed should no longer occur since the count and scan operations are lockless since commit 20cd1892fcc3 ("mm: shrinkers: make count and scan in shrinker debugfs lockless"). However, since this is a contended lock, prefer instead moving `ida_free` outside the lock to avoid the race.

2023-05-17efivarfs: expose used and total sizeAnisse Astier1-0/+11
When writing EFI variables, one might get errors with no other message on why it fails. Being able to see how much is used by EFI variables helps analyzing such issues. Since this is not a conventional filesystem, block size is intentionally set to 1 instead of PAGE_SIZE. x86 quirks of reserved size are taken into account; so that available and free size can be different, further helping debugging space issues. With this patch, one can see the remaining space in EFI variable storage via efivarfs, like this: $ df -h /sys/firmware/efi/efivars/ Filesystem Size Used Avail Use% Mounted on efivarfs 176K 106K 66K 62% /sys/firmware/efi/efivars Signed-off-by: Anisse Astier <[email protected]> [ardb: - rename efi_reserved_space() to efivar_reserved_space() - whitespace/coding style tweaks] Signed-off-by: Ard Biesheuvel <[email protected]>

Define arrays of strings instead of snd_kcontrol_new.

And add some static asserts to verify that the array sizes match. This also applies the compactization from the previous commit to the destination registers. While reshuffling the arrays anyway, switch the order of the HAMOA_DAC & HANA_SPDIF output destinations for the 1010 card, so they follow a more regular pattern. This should have no functional impact. The code is somewhat de-duplicated by the extraction of add_ctls().

Many registers are meaningless for stereo slaves and the extra voices.

It's not called for the extra voices any more. Accordingly, snd_emu10k1_playback_mute_voice() is factored out from snd_emu10k1_playback_stop_voice(), and is called selectively as well.

2023-05-17fs: fix undefined behavior in bit shift for SB_NOUSERHao Ge1-21/+21
Shifting signed 32-bit value by 31 bits is undefined, so changing significant bit to unsigned. It was spotted by UBSAN. So let's just fix this by using the BIT() helper for all SB_* flags.

2023-05-17procfs: consolidate arch_report_meminfo declarationArnd Bergmann1-0/+2
The arch_report_meminfo() function is provided by four architectures, with a __weak fallback in procfs itself. On architectures that don't have a custom version, the __weak version causes a warning because of the missing prototype. Remove the architecture specific prototypes and instead add one in linux/proc_fs.h.

2023-05-16fortify: Add protection for strlcat()Kees Cook1-0/+64
The definition of strcat() was defined in terms of unfortified strlcat(), but that meant there was no bounds checking done on the internal strlen() calls, and the (bounded) copy would be performed before reporting a failure. Additionally, pathological cases (i.e. unterminated destination buffer) did not make calls to fortify_panic(), which will make future unit testing more difficult. Instead, explicitly define a fortified strlcat() wrapper for strcat() to use. Signed-off-by: Kees Cook <[email protected]>
