commit 8ff60eb052eeba95cfb3efe16b08c9199f8121cf upstream.
acquire_slab() fails if there is contention on the freelist of the page
(probably because some other CPU is concurrently freeing an object from
the page). In that case, it might make sense to look for a different page
(since there might be more remote frees to the page from other CPUs, and
we don't want contention on struct page).However, the current code accidentally stops looking at the partial list
completely in that case. Especially on kernels without CONFIG_NUMA set,
this means that get_partial() fails and new_slab_objects() falls back to
new_slab(), allocating new pages. This could lead to an unnecessary
increase in memory fragmentation.Link: https://lkml.kernel.org/r/20201228130853.1871516-1-jannh@google.com

[ Upstream commit feb889fb40fafc6933339cf1cca8f770126819fb ]
So technically there is nothing wrong with adding a pinned page to the
swap cache, but the pinning obviously means that the page can't actually
be free'd right now anyway, so it's a bit pointless.However, the real problem is not with it being a bit pointless: the real
issue is that after we've added it to the swap cache, we'll try to unmap
the page. That will succeed, because the code in mm/rmap.c doesn't know
or care about pinned pages.Even the unmapping isn't fatal per se, since the page will stay around
in memory due to the pinning, and we do hold the connection to it using
the swap cache. But when we then touch it next and take a page fault,
the logic in do_swap_page() will map it back into the process as a
possibly read-only page, and we'll then break the page association on
the next COW fault.Honestly, this issue could have been fixed in any of those other places:
(a) we could refuse to unmap a pinned page (which makes conceptual
sense), or (b) we could make sure to re-map a pinned page writably in
do_swap_page(), or (c) we could just make do_wp_page() not COW the
pinned page (which was what we historically did before that "mm:
do_wp_page() simplification" commit).But while all of them are equally valid models for breaking this chain,
not putting pinned pages into the swap cache in the first place is the
simplest one by far.It's also the safest one: the reason why do_wp_page() was changed in the
first place was that getting the "can I re-use this page" wrong is so
fraught with errors. If you do it wrong, you end up with an incorrectly
shared page.As a result, using "page_maybe_dma_pinned()" in either do_wp_page() or
do_swap_page() would be a serious bug since it is only a (very good)
heuristic. Re-using the page requires a hard black-and-white rule with
no room for ambiguity.In contrast, saying "this page is very likely dma pinned, so let's not
add it to the swap cache and try to unmap it" is an obviously safe thing
to do, and if the heuristic might very rarely be a false positive, no
harm is done.Fixes: 09854ba94c6a ("mm: do_wp_page() simplification")

In the Scudo memory allocator [1] we would like to be able to detect
use-after-free vulnerabilities involving large allocations by issuing
mprotect(PROT_NONE) on the memory region used for the allocation when it
is deallocated. Later on, after the memory region has been "quarantined"
for a sufficient period of time we would like to be able to use it for
another allocation by issuing mprotect(PROT_READ|PROT_WRITE).Before this patch, after removing the write protection, any writes to the
memory region would result in page faults and entering the copy-on-write
code path, even in the usual case where the pages are only referenced by a
single PTE, harming performance unnecessarily. Make it so that any pages
in anonymous mappings that are only referenced by a single PTE are
immediately made writable during the mprotect so that we can avoid the
page faults.This program shows the critical syscall sequence that we intend to use in
the allocator:#include
#includeenum { kSize = 131072 };
int main(int argc, char **argv) {
char *addr = (char *)mmap(0, kSize, PROT_READ | PROT_WRITE,
MAP_ANONYMOUS | MAP_PRIVATE, -1, 0);
for (int i = 0; i != 100000; ++i) {
memset(addr, i, kSize);
mprotect((void *)addr, kSize, PROT_NONE);
mprotect((void *)addr, kSize, PROT_READ | PROT_WRITE);
}
}The effect of this patch on the above program was measured on a
DragonBoard 845c by taking the median real time execution time of 10 runs.Before: 3.19s
After: 0.79sThe effect was also measured using one of the microbenchmarks that
we normally use to benchmark the allocator [2], after modifying it
to make the appropriate mprotect calls [3]. With an allocation size
of 131072 bytes to trigger the allocator's "large allocation" code
path the per-iteration time was measured as follows:Before: 33364ns
After: 6886nsThis patch means that we do more work during the mprotect call itself
in exchange for less work when the pages are accessed. In the worst
case, the pages are not accessed at all. The effect of this patch in
such cases was measured using the following program:#include
#includeenum { kSize = 131072 };
int main(int argc, char **argv) {
char *addr = (char *)mmap(0, kSize, PROT_READ | PROT_WRITE,
MAP_ANONYMOUS | MAP_PRIVATE, -1, 0);
memset(addr, 1, kSize);
for (int i = 0; i != 100000; ++i) {
#ifdef PAGE_FAULT
memset(addr + (i * 4096) % kSize, i, 4096);
#endif
mprotect((void *)addr, kSize, PROT_NONE);
mprotect((void *)addr, kSize, PROT_READ | PROT_WRITE);
}
}With PAGE_FAULT undefined (0 pages touched after removing write
protection) the median real time execution time of 100 runs was measured
as follows:Before: 0.325928s
After: 0.365493sWith PAGE_FAULT defined (1 page touched) the measurements were
as follows:Before: 0.441516s
After: 0.380251sSo it seems that even with a single page fault the new approach is faster.
I saw similar results if I adjusted the programs to use a larger mapping
size. With kSize = 1048576 I get these numbers with PAGE_FAULT undefined:Before: 1.563078s
After: 1.607476si.e. around 3%.
And these with PAGE_FAULT defined:
Before: 1.684663s
After: 1.683272si.e. about the same.
What I think we may conclude from these results is that for smaller
mappings the advantage of the previous approach, although measurable, is
wiped out by a single page fault. I think we may expect that there should
be at least one access resulting in a page fault (under the previous
approach) after making the pages writable, since the program presumably
made the pages writable for a reason.For larger mappings we may guesstimate that the new approach wins if the
density of future page faults is > 0.4%. But for the mappings that are
large enough for density to matter (not just the absolute number of page
faults) it doesn't seem like the increase in mprotect latency would be
very large relative to the total mprotect execution time.Link: https://lkml.kernel.org/r/20201230004134.1185017-1-pcc@google.com

commit c2407cf7d22d0c0d94cf20342b3b8f06f1d904e7 upstream.
Ever since commit 2a9127fcf229 ("mm: rewrite wait_on_page_bit_common()
logic") we've had some very occasional reports of BUG_ON(PageWriteback)
in write_cache_pages(), which we thought we already fixed in commit
073861ed77b6 ("mm: fix VM_BUG_ON(PageTail) and BUG_ON(PageWriteback)").But syzbot just reported another one, even with that commit in place.
And it turns out that there's a simpler way to trigger the BUG_ON() than
the one Hugh found with page re-use. It all boils down to the fact that
the page writeback is ostensibly serialized by the page lock, but that
isn't actually really true.Yes, the people _setting_ writeback all do so under the page lock, but
the actual clearing of the bit - and waking up any waiters - happens
without any page lock.This gives us this fairly simple race condition:
CPU1 = end previous writeback
CPU2 = start new writeback under page lock
CPU3 = write_cache_pages()CPU1 CPU2 CPU3
---- ---- ----end_page_writeback()
test_clear_page_writeback(page)
... delayed...lock_page();
set_page_writeback()
unlock_page()lock_page()
wait_on_page_writeback();wake_up_page(page, PG_writeback);
.. wakes up CPU3 ..BUG_ON(PageWriteback(page));
where the BUG_ON() happens because we woke up the PG_writeback bit
becasue of the _previous_ writeback, but a new one had already been
started because the clearing of the bit wasn't actually atomic wrt the
actual wakeup or serialized by the page lock.The reason this didn't use to happen was that the old logic in waiting
on a page bit would just loop if it ever saw the bit set again.The nice proper fix would probably be to get rid of the whole "wait for
writeback to clear, and then set it" logic in the writeback path, and
replace it with an atomic "wait-to-set" (ie the same as we have for page
locking: we set the page lock bit with a single "lock_page()", not with
"wait for lock bit to clear and then set it").However, out current model for writeback is that the waiting for the
writeback bit is done by the generic VFS code (ie write_cache_pages()),
but the actual setting of the writeback bit is done much later by the
filesystem ".writepages()" function.IOW, to make the writeback bit have that same kind of "wait-to-set"
behavior as we have for page locking, we'd have to change our roughly
~50 different writeback functions. Painful.Instead, just make "wait_on_page_writeback()" loop on the very unlikely
situation that the PG_writeback bit is still set, basically re-instating
the old behavior. This is very non-optimal in case of contention, but
since we only ever set the bit under the page lock, that situation is
controlled.Reported-by: syzbot+2fc0712f8f8b8b8fa0ef@syzkaller.appspotmail.com

Memory hotplugging is allowed only for multiples of section sizes.
Section size could be huge (ex. 1GB for arm64 targets) thus limiting
to add/remove lower chunks of memory. This patch allows drivers to add
memory of subsection sizes which are then added to memblock. This does
not create a separate memblock device nodes for newly added subsections
until the whole of the memblock section is added.Bug: 170460867

Collect the time for each allocation recorded in page owner so that
allocation "surges" can be measured.Record the pid for each allocation recorded in page owner so that the
source of allocation "surges" can be better identified.The above is very useful when doing memory analysis. On a crash for
example, we can get this information from kdump (or ramdump) and parse it
to figure out memory allocation problems.Please note that on x86_64 this increases the size of struct page_owner
from 16 bytes to 32.Vlastimil: it's not a functionality intended for production, so unless
somebody says they need to enable page_owner for debugging and this
increase prevents them from fitting into available memory, let's not
complicate things with making this optional.[lmark@codeaurora.org: v3]

Free the pages parallely for a task that receives SIGKILL, from ULMK
process, using the oom_reaper. This freeing of pages will help to give
the pages to buddy system well advance.Add the boot param, reap_mem_when_killed_by=, that configures the
process name, the kill signal to a process from which makes its memory
reaped by oom reaper.As an example, when reap_mem_when_killed_by=lmkd, then all the processes
that receives the kill signal from lmkd is added to oom reaper.Not initializing this param makes this feature disabled.

commit dc2da7b45ffe954a0090f5d0310ed7b0b37d2bd2 upstream.
VMware observed a performance regression during memmap init on their
platform, and bisected to commit 73a6e474cb376 ("mm: memmap_init:
iterate over memblock regions rather that check each PFN") causing it.Before the commit:
[0.033176] Normal zone: 1445888 pages used for memmap
[0.033176] Normal zone: 89391104 pages, LIFO batch:63
[0.035851] ACPI: PM-Timer IO Port: 0x448With commit
[0.026874] Normal zone: 1445888 pages used for memmap
[0.026875] Normal zone: 89391104 pages, LIFO batch:63
[2.028450] ACPI: PM-Timer IO Port: 0x448The root cause is the current memmap defer init doesn't work as expected.
Before, memmap_init_zone() was used to do memmap init of one whole zone,
to initialize all low zones of one numa node, but defer memmap init of
the last zone in that numa node. However, since commit 73a6e474cb376,
function memmap_init() is adapted to iterater over memblock regions
inside one zone, then call memmap_init_zone() to do memmap init for each
region.E.g, on VMware's system, the memory layout is as below, there are two
memory regions in node 2. The current code will mistakenly initialize the
whole 1st region [mem 0xab00000000-0xfcffffffff], then do memmap defer to
iniatialize only one memmory section on the 2nd region [mem
0x10000000000-0x1033fffffff]. In fact, we only expect to see that there's
only one memory section's memmap initialized. That's why more time is
costed at the time.[ 0.008842] ACPI: SRAT: Node 0 PXM 0 [mem 0x00000000-0x0009ffff]
[ 0.008842] ACPI: SRAT: Node 0 PXM 0 [mem 0x00100000-0xbfffffff]
[ 0.008843] ACPI: SRAT: Node 0 PXM 0 [mem 0x100000000-0x55ffffffff]
[ 0.008844] ACPI: SRAT: Node 1 PXM 1 [mem 0x5600000000-0xaaffffffff]
[ 0.008844] ACPI: SRAT: Node 2 PXM 2 [mem 0xab00000000-0xfcffffffff]
[ 0.008845] ACPI: SRAT: Node 2 PXM 2 [mem 0x10000000000-0x1033fffffff]Now, let's add a parameter 'zone_end_pfn' to memmap_init_zone() to pass
down the real zone end pfn so that defer_init() can use it to judge
whether defer need be taken in zone wide.Link: https://lkml.kernel.org/r/20201223080811.16211-1-bhe@redhat.com

commit e7dd91c456a8cdbcd7066997d15e36d14276a949 upstream.
syzbot reported the deadlock here [1]. The issue is in hugetlb cow
error handling when there are not enough huge pages for the faulting
task which took the original reservation. It is possible that other
(child) tasks could have consumed pages associated with the reservation.
In this case, we want the task which took the original reservation to
succeed. So, we unmap any associated pages in children so that they can
be used by the faulting task that owns the reservation.The unmapping code needs to hold i_mmap_rwsem in write mode. However,
due to commit c0d0381ade79 ("hugetlbfs: use i_mmap_rwsem for more pmd
sharing synchronization") we are already holding i_mmap_rwsem in read
mode when hugetlb_cow is called.Technically, i_mmap_rwsem does not need to be held in read mode for COW
mappings as they can not share pmd's. Modifying the fault code to not
take i_mmap_rwsem in read mode for COW (and other non-sharable) mappings
is too involved for a stable fix.Instead, we simply drop the hugetlb_fault_mutex and i_mmap_rwsem before
unmapping. This is OK as it is technically not needed. They are
reacquired after unmapping as expected by calling code. Since this is
done in an uncommon error path, the overhead of dropping and reacquiring
mutexes is acceptable.While making changes, remove redundant BUG_ON after unmap_ref_private.

commit fc5488651c7d840c9cad9b0f273f2f31bd03413a upstream.
Patch series "z3fold: stability / rt fixes".
Address z3fold stability issues under stress load, primarily in the
reclaim and free aspects. Besides, it fixes the locking problems that
were only seen in real-time kernel configuration.This patch (of 3):
There used to be two places in the code where slots could be freed, namely
when freeing the last allocated handle from the slots and when releasing
the z3fold header these slots aree linked to. The logic to decide on
whether to free certain slots was complicated and error prone in both
functions and it led to failures in RT case.To fix that, make free_handle() the single point of freeing slots.

[ Upstream commit 597c892038e08098b17ccfe65afd9677e6979800 ]
On 2-node NUMA hosts we see bursts of kswapd reclaim and subsequent
pressure spikes and stalls from cache refaults while there is plenty of
free memory in the system.Usually, kswapd is woken up when all eligible nodes in an allocation are
full. But the code related to watermark boosting can wake kswapd on one
full node while the other one is mostly empty. This may be justified to
fight fragmentation, but is currently unconditionally done whether
watermark boosting is occurring or not.In our case, many of our workloads' throughput scales with available
memory, and pure utilization is a more tangible concern than trends
around longer-term fragmentation. As a result we generally disable
watermark boosting.Wake kswapd only woken when watermark boosting is requested.

[ Upstream commit 1e8aaedb182d6ddffc894b832e4962629907b3e0 ]
madvise_inject_error() uses get_user_pages_fast to translate the address
we specified to a page. After [1], we drop the extra reference count for
memory_failure() path. That commit says that memory_failure wanted to
keep the pin in order to take the page out of circulation.The truth is that we need to keep the page pinned, otherwise the page
might be re-used after the put_page() and we can end up messing with
someone else's memory.E.g:
CPU0
process X CPU1
madvise_inject_error
get_user_pages
put_page
page gets reclaimed
process Y allocates the page
memory_failure
// We mess with process Y memorymadvise() is meant to operate on a self address space, so messing with
pages that do not belong to us seems the wrong thing to do.
To avoid that, let us keep the page pinned for memory_failure as well.Pages for DAX mappings will release this extra refcount in
memory_failure_dev_pagemap.[1] ("23e7b5c2e271: mm, madvise_inject_error:
Let memory_failure() optionally take a page reference")Link: https://lkml.kernel.org/r/20201207094818.8518-1-osalvador@suse.de

[ Upstream commit c041098c690fe53cea5d20c62f128a4f7a5c19fe ]
The size of vm area can be affected by the presence or not of the guard
page. In particular when VM_NO_GUARD is present, the actual accessible
size has to be considered like the real size minus the guard page.Currently kasan does not keep into account this information during the
poison operation and in particular tries to poison the guard page as well.This approach, even if incorrect, does not cause an issue because the tags
for the guard page are written in the shadow memory. With the future
introduction of the Tag-Based KASAN, being the guard page inaccessible by
nature, the write tag operation on this page triggers a fault.Fix kasan shadow poisoning size invoking get_vm_area_size() instead of
accessing directly the field in the data structure to detect the correct
value.Link: https://lkml.kernel.org/r/20201027160213.32904-1-vincenzo.frascino@arm.com
