2020-04-24mm: check that mm is still valid in madvise()Linus Torvalds
IORING_OP_MADVISE can end up basically doing mprotect() on the VM of another process, which means that it can race with our crazy core dump handling which accesses the VM state without holding the mmap_sem (because it incorrectly thinks that it is the final user). This is clearly a core dumping problem, but we've never fixed it the right way, and instead have the notion of "check that the mm is still ok" using mmget_still_valid() after getting the mmap_sem for writing in any situation where we're not the original VM thread. See commit 04f5866e41fb ("coredump: fix race condition between mmget_not_zero()/get_task_mm() and core dumping") for more background on this whole mmget_still_valid() thing. You might want to have a barf bag handy when you do. We're discussing just fixing this properly in the only remaining core dumping routines. But even if we do that, let's make do_madvise() do the right thing, and then when we fix core dumping, we can remove all these mmget_still_valid() checks.

AFS keeps track of the epoch value from the rxrpc protocol to note (a) when a fileserver appears to have restarted and (b) when different endpoints of a fileserver do not appear to be associated with the same fileserver (ie. all probes back from a fileserver from all of its interfaces should carry the same epoch). However, the AFS_SERVER_FL_HAVE_EPOCH flag that indicates that we've received the server's epoch is never set, though it is used. Fix this to set the flag when we first receive an epoch value from a probe sent to the filesystem client from the fileserver.

2020-04-23null_blk: Fix zoned command handlingDamien Le Moal
For write operations issued to a null_blk device with zoned mode enabled, the state and write pointer position of the zone targeted by the command should be checked before badblocks and memory backing are handled as the write may be first failed due to, for instance, a sector position not aligned with the zone write pointer. This order of checking for errors reflects more accuratly the behavior of physical zoned devices. Furthermore, the write pointer position of the target zone should be incremented only and only if no errors are reported by badblocks and memory backing handling. To fix this, introduce the small helper function null_process_cmd() which execute null_handle_badblocks() and null_handle_memory_backed() and use this function in null_zone_write() to correctly handle write requests to zoned null devices depending on the type and state of the write target zone. Also call this function in null_handle_zoned() to process read requests to zoned null devices. null_process_cmd() is called directly from null_handle_cmd() for regular null devices, resulting in no functional change for these type of devices. To have symmetric names, the function null_handle_zoned() is renamed to null_process_zoned_cmd().

2020-04-23ALSA: hda: Always use jackpoll helper for jack update after resumeTakashi Iwai
HD-audio codec driver applies a tricky procedure to forcibly perform the runtime resume by mimicking the usage count even if the device has been runtime-suspended beforehand. This was needed to assure to trigger the jack detection update after the system resume. And recently we also applied the similar logic to the HD-audio controller side. However this seems leading to some inconsistency, and eventually PCI controller gets screwed up. This patch is an attempt to fix and clean up those behavior: instead of the tricky runtime resume procedure, the existing jackpoll work is scheduled when such a forced codec resume is required. The jackpoll work will power up the codec, and this alone should suffice for the jack status update in usual cases. If the extra polling is requested (by checking codec->jackpoll_interval), the manual update is invoked after that, and the codec is powered down again. Also, we filter the spurious wake up of the codec from the controller runtime resume by checking codec->relaxed_resume flag. If this flag is set, basically we don't need to wake up explicitly, but it's supposed to be done via the audio component notifier. Fixes: c4c8dd6ef807 ("ALSA: hda: Skip controller resume if not needed") Link: https://lore.kernel.org/r/20200422203744.26299-1-tiwai@suse.de Signed-off-by: Takashi Iwai <tiwai@suse.de>

2020-04-23ALSA: usb-audio: Fix usb audio refcnt leak when getting spdifXiyu Yang
snd_microii_spdif_default_get() invokes snd_usb_lock_shutdown(), which increases the refcount of the snd_usb_audio object "chip". When snd_microii_spdif_default_get() returns, local variable "chip" becomes invalid, so the refcount should be decreased to keep refcount balanced. The reference counting issue happens in several exception handling paths of snd_microii_spdif_default_get(). When those error scenarios occur such as usb_ifnum_to_if() returns NULL, the function forgets to decrease the refcnt increased by snd_usb_lock_shutdown(), causing a refcnt leak. Fix this issue by jumping to "end" label when those error scenarios occur.

2020-04-23arch: split MODULE_ARCH_VERMAGIC definitions out to <asm/vermagic.h>Masahiro Yamada
As the bug report [1] pointed out, <linux/vermagic.h> must be included after <linux/module.h>. I believe we should not impose any include order restriction. We often sort include directives alphabetically, but it is just coding style convention. Technically, we can include header files in any order by making every header self-contained. Currently, arch-specific MODULE_ARCH_VERMAGIC is defined in <asm/module.h>, which is not included from <linux/vermagic.h>. Hence, the straight-forward fix-up would be as follows: |--- a/include/linux/vermagic.h |+++ b/include/linux/vermagic.h |@@ -1,5 +1,6 @@ | /* SPDX-License-Identifier: GPL-2.0 */ | #include <generated/utsrelease.h> |+#include <linux/module.h> | | /* Simply sanity version stamp for modules. */ | #ifdef CONFIG_SMP This works enough, but for further cleanups, I split MODULE_ARCH_VERMAGIC definitions into <asm/vermagic.h>. With this, <linux/module.h> and <linux/vermagic.h> will be orthogonal, and the location of MODULE_ARCH_VERMAGIC definitions will be consistent. For arc and ia64, MODULE_PROC_FAMILY is only used for defining MODULE_ARCH_VERMAGIC. I squashed it. For hexagon, nds32, and xtensa, I removed <asm/modules.h> entirely because they contained nothing but MODULE_ARCH_VERMAGIC definition. Kbuild will automatically generate <asm/modules.h> at build-time, wrapping <asm-generic/module.h>.

Since commit 7a0496056064 ("kbuild: fix DT binding schema rule to detect command line changes"), this rule is every time re-run even if you change nothing. cmd_dtc takes one additional parameter to pass to the -O option of dtc. We need to pass 'yaml' to if_changed_rule. Otherwise, cmd-check invoked from if_changed_rule is false positive.
