mm: vmpressure: fix dual calls to global vmpressure
vmpressure function is invoked multiple time from shrink_node, once for each memcg and then for the entire subtree. But global vmpressure calculation is performed for each of these calls resulting in window period ending fast. This is not a problem when CONFIG_MEMCG is enabled, as global vmpressure is not used in that case. With !CONFIG_MEMCG global vmpressure is called twice. Fix this.

mm/kmemleak.c: wait for scan completion before disabling free
A crash is observed when kmemleak_scan accesses the object->pointer,
likely due to the following race.
TASK A TASK B TASK C
kmemleak_write
(with "scan" and
NOT "scan=on")
kmemleak_scan()
create_object
kmem_cache_alloc fails
kmemleak_disable
kmemleak_do_cleanup
kmemleak_free_enabled = 0
kfree
kmemleak_free bails out
(kmemleak_free_enabled is 0)
slub frees object->pointer
update_checksum
crash - object->pointer
freed (DEBUG_PAGEALLOC)
kmemleak_do_cleanup waits for the scan thread to complete, but not for
direct call to kmemleak_scan via kmemleak_write. So add a wait for
kmemleak_scan completion before disabling kmemleak_free, and while at it
fix the comment on stop_scan_thread.
[vinmenon@codeaurora.org: fix stop_scan_thread comment]

mm/shmem: do not wait for lock_page() in shmem_unused_huge_shrink()
commit b3cd54b257ad95d344d121dc563d943ca39b0921 upstream.
shmem_unused_huge_shrink() gets called from reclaim path. Waiting for
page lock may lead to deadlock there.
There was a bug report that may be attributed to this:
http://lkml.kernel.org/r/alpine.LRH.2.11.1801242349220.30642@mail.ewheeler.net
Replace lock_page() with trylock_page() and skip the page if we failed
to lock it. We will get to the page on the next scan.
We can test for the PageTransHuge() outside the page lock as we only
need protection against splitting the page under us. Holding pin oni
the page is enough for this.

mm/khugepaged.c: convert VM_BUG_ON() to collapse fail
commit fece2029a9e65b9a990831afe2a2b83290cbbe26 upstream.
khugepaged is not yet able to convert PTE-mapped huge pages back to PMD
mapped. We do not collapse such pages. See check
khugepaged_scan_pmd().
But if between khugepaged_scan_pmd() and __collapse_huge_page_isolate()
somebody managed to instantiate THP in the range and then split the PMD
back to PTEs we would have a problem --
VM_BUG_ON_PAGE(PageCompound(page)) will get triggered.
It's possible since we drop mmap_sem during collapse to re-take for
write.
Replace the VM_BUG_ON() with graceful collapse fail.

mm, oom: remove 3% bonus for CAP_SYS_ADMIN processes
Since the 2.6 kernel, the oom killer has slightly biased away from CAP_SYS_ADMIN processes by discounting some of its memory usage in comparison to other processes. This has always been implicit and nothing exactly relies on the behavior. Gaurav notices that __task_cred() can dereference a potentially freed pointer if the task under consideration is exiting because a reference to the task_struct is not held. Remove the CAP_SYS_ADMIN bias so that all processes are treated equally. If any CAP_SYS_ADMIN process would like to be biased against, it is always allowed to adjust /proc/pid/oom_score_adj.

mm: hwpoison: call shake_page() after try_to_unmap() for mlocked page
[ Upstream commit 286c469a988fbaf68e3a97ddf1e6c245c1446968 ]
Memory error handler calls try_to_unmap() for error pages in various
states. If the error page is a mlocked page, error handling could fail
with "still referenced by 1 users" message. This is because the page is
linked to and stays in lru cache after the following call chain.
try_to_unmap_one
page_remove_rmap
clear_page_mlock
putback_lru_page
lru_cache_add
memory_failure() calls shake_page() to hanlde the similar issue, but
current code doesn't cover because shake_page() is called only before
try_to_unmap(). So this patches adds shake_page().

mm, vmstat: suppress pcp stats for unpopulated zones in zoneinfo
[ Upstream commit 7dfb8bf3b9caef4049bee51d2c22e1c3a311d483 ] After "mm, vmstat: print non-populated zones in zoneinfo", /proc/zoneinfo will show unpopulated zones. The per-cpu pageset statistics are not relevant for unpopulated zones and can be potentially lengthy, so supress them when they are not interesting. Also moves lowmem reserve protection information above pcp stats since it is relevant for all zones per vm.lowmem_reserve_ratio.

mm: fix check for reclaimable pages in PF_MEMALLOC reclaim throttling
[ Upstream commit d450abd81b081d45adb12f303a07dd44b15eb1bc ]
PF_MEMALLOC direct reclaimers get throttled on a node when the sum of
all free pages in each zone fall below half the min watermark. During
the summation, we want to exclude zones that don't have reclaimables.
Checking the same pgdat over and over again doesn't make sense.

mm: ratelimit swap write errors
Ratelimit the swap write errors to avoid logbuf getting filled up by these messages. These pages remove the useful page allocation failure messages (when zram is used as swap) from logbuf, thus making the debugging difficult.

UPSTREAM: kasan: add functions for unpoisoning stack variables
As a code-size optimization, LLVM builds since r279383 may bulk-manipulate the shadow region when (un)poisoning large memory blocks. This requires new callbacks that simply do an uninstrumented memset(). This fixes linking the Clang-built kernel when using KASAN.

UPSTREAM: kasan: support alloca() poisoning
clang's AddressSanitizer implementation adds redzones on either side of alloca()ed buffers. These redzones are 32-byte aligned and at least 32 bytes long. __asan_alloca_poison() is passed the size and address of the allocated buffer, *excluding* the redzones on either side. The left redzone will always be to the immediate left of this buffer; but AddressSanitizer may need to add padding between the end of the buffer and the right redzone. If there are any 8-byte chunks inside this padding, we should poison those too. __asan_allocas_unpoison() is just passed the top and bottom of the dynamic stack area, so unpoisoning is simpler.

mm: fail get_vaddr_frames() for filesystem-dax mappings
commit b7f0554a56f21fb3e636a627450a9add030889be upstream.
Until there is a solution to the dma-to-dax vs truncate problem it is
not safe to allow V4L2, Exynos, and other frame vector users to create
long standing / irrevocable memory registrations against filesytem-dax
vmas.

mm: introduce get_user_pages_longterm
commit 2bb6d2837083de722bfdc369cb0d76ce188dd9b4 upstream.
Patch series "introduce get_user_pages_longterm()", v2.
Here is a new get_user_pages api for cases where a driver intends to
keep an elevated page count indefinitely. This is distinct from usages
like iov_iter_get_pages where the elevated page counts are transient.
The iov_iter_get_pages cases immediately turn around and submit the
pages to a device driver which will put_page when the i/o operation
completes (under kernel control).
In the longterm case userspace is responsible for dropping the page
reference at some undefined point in the future. This is untenable for
filesystem-dax case where the filesystem is in control of the lifetime
of the block / page and needs reasonable limits on how long it can wait
for pages in a mapping to become idle.
Fixing filesystems to actually wait for dax pages to be idle before
blocks from a truncate/hole-punch operation are repurposed is saved for
a later patch series.
Also, allowing longterm registration of dax mappings is a future patch
series that introduces a "map with lease" semantic where the kernel can
revoke a lease and force userspace to drop its page references.
I have also tagged these for -stable to purposely break cases that might
assume that longterm memory registrations for filesystem-dax mappings
were supported by the kernel. The behavior regression this policy
change implies is one of the reasons we maintain the "dax enabled.
Warning: EXPERIMENTAL, use at your own risk" notification when mounting
a filesystem in dax mode.
It is worth noting the device-dax interface does not suffer the same
constraints since it does not support file space management operations
like hole-punch.
This patch (of 4):
Until there is a solution to the dma-to-dax vs truncate problem it is
not safe to allow long standing memory registrations against
filesytem-dax vmas. Device-dax vmas do not have this problem and are
explicitly allowed.
This is temporary until a "memory registration with layout-lease"
mechanism can be implemented for the affected sub-systems (RDMA and
V4L2).

Currently we wait for all cgwbs to get released in cgwb_bdi_destroy() (called from bdi_unregister()). That is however unnecessary now when cgwb->bdi is a proper refcounted reference (thus bdi cannot get released before all cgwbs are released) and when cgwb_bdi_destroy() shuts down writeback directly.

bdi: Shutdown writeback on all cgwbs in cgwb_bdi_destroy()
Currently we waited for all cgwbs to get freed in cgwb_bdi_destroy() which also means that writeback has been shutdown on them. Since this wait is going away, directly shutdown writeback on cgwbs from cgwb_bdi_destroy() to avoid live writeback structures after bdi_unregister() has finished. To make that safe with concurrent shutdown from cgwb_release_workfn(), we also have to make sure wb_shutdown() returns only after the bdi_writeback structure is really shutdown.

bdi: Unify bdi->wb_list handling for root wb_writeback
Currently root wb_writeback structure is added to bdi->wb_list in bdi_init() and never removed. That is different from all other wb_writeback structures which get added to the list when created and removed from it before wb_shutdown(). So move list addition of root bdi_writeback to bdi_register() and list removal of all wb_writeback structures to wb_shutdown(). That way a wb_writeback structure is on bdi->wb_list if and only if it can handle writeback and it will make it easier for us to handle shutdown of all wb_writeback structures in bdi_unregister().

bdi: Mark congested->bdi as internal
congested->bdi pointer is used only to be able to remove congested structure from bdi->cgwb_congested_tree on structure release. Moreover the pointer can become NULL when we unregister the bdi. Rename the field to __bdi and add a comment to make it more explicit this is internal stuff of memcg writeback code and people should not use the field as such use will be likely race prone. We do not bother with converting congested->bdi to a proper refcounted reference. It will be slightly ugly to special-case bdi->wb.congested to avoid effectively a cyclic reference of bdi to itself and the reference gets cleared from bdi_unregister() making it impossible to reference a freed bdi.

bdi: Fix use-after-free in wb_congested_put()
bdi_writeback_congested structures get created for each blkcg and bdi regardless whether bdi is registered or not. When they are created in unregistered bdi and the request queue (and thus bdi) is then destroyed while blkg still holds reference to bdi_writeback_congested structure, this structure will be referencing freed bdi and last wb_congested_put() will try to remove the structure from already freed bdi. With commit 165a5e22fafb "block: Move bdi_unregister() to del_gendisk()", SCSI started to destroy bdis without calling bdi_unregister() first (previously it was calling bdi_unregister() even for unregistered bdis) and thus the code detaching bdi_writeback_congested in cgwb_bdi_destroy() was not triggered and we started hitting this use-after-free-bug. It is enough to boot a KVM instance with virtio-scsi device to trigger this behavior. Fix the problem by detaching bdi_writeback_congested structures in bdi_exit() instead of bdi_unregister(). This is also more logical as they can get attached to bdi regardless whether it ever got registered or not.

block: Allow bdi re-registration
SCSI can call device_add_disk() several times for one request queue when a device in unbound and bound, creating new gendisk each time. This will lead to bdi being repeatedly registered and unregistered. This was not a big problem until commit 165a5e22fafb "block: Move bdi_unregister() to del_gendisk()" since bdi was only registered repeatedly (bdi_register() handles repeated calls fine, only we ended up leaking reference to gendisk due to overwriting bdi->owner) but unregistered only in blk_cleanup_queue() which didn't get called repeatedly. After 165a5e22fafb we were doing correct bdi_register() - bdi_unregister() cycles however bdi_unregister() is not prepared for it. So make sure bdi_unregister() cleans up bdi in such a way that it is prepared for a possible following bdi_register() call. An easy way to provoke this behavior is to enable CONFIG_DEBUG_TEST_DRIVER_REMOVE and use scsi_debug driver to create a scsi disk which immediately hangs without this fix.

block: Use pointer to backing_dev_info from request_queue
We will want to have struct backing_dev_info allocated separately from struct request_queue. As the first step add pointer to backing_dev_info to request_queue and convert all users touching it. No functional changes in this patch.

shmem: fix compilation warnings on unused functions
commit f1f5929cd9715c1cdfe07a890f12ac7d2c5304ec upstream.
Compiling shmem.c with SHMEM and TRANSAPRENT_HUGE_PAGECACHE enabled
raises warnings on two unused functions when CONFIG_TMPFS and
CONFIG_SYSFS are both disabled:
mm/shmem.c:390:20: warning: `shmem_format_huge' defined but not used [-Wunused-function]
static const char *shmem_format_huge(int huge)
^~~~~~~~~~~~~~~~~
mm/shmem.c:373:12: warning: `shmem_parse_huge' defined but not used [-Wunused-function]
static int shmem_parse_huge(const char *str)
^~~~~~~~~~~~~~~~
A conditional compilation on tmpfs or sysfs removes the warnings.

shmem: avoid maybe-uninitialized warning
commit 23f919d4ad0eb325595f10f55be4301b2965d6d6 upstream. After enabling -Wmaybe-uninitialized warnings, we get a false-postive warning for shmem: mm/shmem.c: In function `shmem_getpage_gfp': include/linux/spinlock.h:332:21: error: `info' may be used uninitialized in this function [-Werror=maybe-uninitialized] This can be easily avoided, since the correct 'info' pointer is known at the time we first enter the function, so we can simply move the initialization up. Moving it before the first label avoids the warning and lets us remove two later initializations. Note that the function is so hard to read that it not only confuses the compiler, but also most readers and without this patch it could\ easily break if one of the 'goto's changed.

mm/early_ioremap: Fix boot hang with earlyprintk=efi,keep
[ Upstream commit 7f6f60a1ba52538c16f26930bfbcfe193d9d746a ]
earlyprintk=efi,keep does not work any more with a warning
in mm/early_ioremap.c: WARN_ON(system_state != SYSTEM_BOOTING):
Boot just hangs because of the earlyprintk within the earlyprintk
implementation code itself.
This is caused by a new introduced middle state in:
69a78ff226fe ("init: Introduce SYSTEM_SCHEDULING state")
early_ioremap() is fine in both SYSTEM_BOOTING and SYSTEM_SCHEDULING
states, original condition should be updated accordingly.

Provide a function to create a NUL-terminated string from unterminated data
commit f35157417215ec138c920320c746fdb3e04ef1d5 upstream. Provide a function, kmemdup_nul(), that will create a NUL-terminated string from an unterminated character array where the length is known in advance. This is better than kstrndup() in situations where we already know the string length as the strnlen() in kstrndup() is superfluous.

mm: hide a #warning for COMPILE_TEST
commit af27d9403f5b80685b79c88425086edccecaf711 upstream.
We get a warning about some slow configurations in randconfig kernels:
mm/memory.c:83:2: error: #warning Unfortunate NUMA and NUMA Balancing config, growing page-frame for last_cpupid. [-Werror=cpp]
The warning is reasonable by itself, but gets in the way of randconfig
build testing, so I'm hiding it whenever CONFIG_COMPILE_TEST is set.
The warning was added in 2013 in commit

mm: retry more before OOM in the presence of slow shrinkers
Shrinkers like lowmemorykiller makes the decision of killing tasks based on cached levels and also whether previous killed tasks have been reaped. This can delay the reclaim and by this time no progress loops of should_reclaim_retry can reach max retries, thus resulting in premature kills. How fast the no progress loops can complete depends on cpu speed, thus retry until reclaimable pages are too less (when __zone_watermark_ok of shouuld_reclaim_retry fails) in the case of slow shrinkers. This fixes premature order 0 OOMs. Now, for (0 < order < costly order) cases, should_reclaim_retry can bail out fast. The decision to try should_compact_retry is based on progress made in the previous reclaim. A single no progress reclaim can result in OOMs for higher orders. Fix that too.

mm: do not fail non-costly allocs if there are reclaimable pages
should_reclaim_retry can fail for order > 0 allocs even if there are reclaimable pages. The decision to retry is then left to compaction progress in should_compact_retry. Shrinkers like lowmemorykiller which does the reclaim based on page cache levels can take time to free up memory. By this time, compaction can complete scanning (COMPACT_COMPLETE) without success. This results in an early failure (compaction_failed) in should_compact_retry, when there are enough tasks available for lowmemorykiller to kill. This results in premature OOMs. It can be argued, how this condition is different from a case where any reclaimable slab is consuming major part of system's memory. The difference is that for other reclaimable slabs, a pressure equivalent to that put on LRU is put on them, resulting in faster reclaim. But that is the not the case with lowmemorykiller which doesn't even trigger until certain page cache levels are reached, and there can be cases of tasks not available in lower oom_score_adj ranges resulting in no kills. Thus when lowmemorykiller is enabled, retry non-costly allocs till there are enough reclaimable pages and if we are making progress in reclaim. For costly orders leave the decision to existing compaction progress logic. Change-Id: I177cdd11e3f45d7f8fcf02435f7ef5834408fb6f Signed-off-by: Vinayak Menon <vinmenon@codeaurora.org> |

mm: consider killable task's anon as reclaimable
zone_reclaimable_pages which is used by should_reclaim_retry to make a decision on retrying reclaim does not consider anon pages if swap is full. This logic works on systems which rely on OOM to kill tasks and free up memory. But when reclaimers like android lowmemorykiller is used, reclaim should retry enough so that lowmemorykiller is invoked via shrinkers, thus avoiding OOM. This fixes the premature order 0 OOM killer invocations observed when swap is full. Change-Id: I99e6585b5a5dd2d871678c13349e7a62d5aefee0 Signed-off-by: Vinayak Menon <vinmenon@codeaurora.org> |
