2019-06-01mm, compaction: make sure we isolate a valid PFNSuzuki K Poulose
When we have holes in a normal memory zone, we could endup having cached_migrate_pfns which may not necessarily be valid, under heavy memory pressure with swapping enabled ( via __reset_isolation_suitable(), triggered by kswapd). Later if we fail to find a page via fast_isolate_freepages(), we may end up using the migrate_pfn we started the search with, as valid page. This could lead to accessing NULL pointer derefernces like below, due to an invalid mem_section pointer.

2019-06-01kernel/signal.c: trace_signal_deliver when signal_group_exitZhenliang Wei
In the fixes commit, removing SIGKILL from each thread signal mask and executing "goto fatal" directly will skip the call to "trace_signal_deliver". At this point, the delivery tracking of the SIGKILL signal will be inaccurate. Therefore, we need to add trace_signal_deliver before "goto fatal" after executing sigdelset. Note: SEND_SIG_NOINFO matches the fact that SIGKILL doesn't have any info.

2019-06-01mm/gup: continue VM_FAULT_RETRY processing even for pre-faultsMike Rapoport
When get_user_pages*() is called with pages = NULL, the processing of VM_FAULT_RETRY terminates early without actually retrying to fault-in all the pages. If the pages in the requested range belong to a VMA that has userfaultfd registered, handle_userfault() returns VM_FAULT_RETRY *after* user space has populated the page, but for the gup pre-fault case there's no actual retry and the caller will get no pages although they are present. This issue was uncovered when running post-copy memory restore in CRIU after d9c9ce34ed5c ("x86/fpu: Fault-in user stack if copy_fpstate_to_sigframe() fails"). After this change, the copying of FPU state to the sigframe switched from copy_to_user() variants which caused a real page fault to get_user_pages() with pages parameter set to NULL. In post-copy mode of CRIU, the destination memory is managed with userfaultfd and lack of the retry for pre-fault case in get_user_pages() causes a crash of the restored process. Making the pre-fault behavior of get_user_pages() the same as the "normal" one fixes the issue.

You have to have a new enough systemd, e.g. 241 (the reason is unknown -- was not investigated). Cannot be reproduced with systemd 234. The system crashes because the size of lru array is never updated in memcg_update_all_list_lrus and the reads are past the zero-sized array, causing dereferences of random memory. The root cause are list_lru_memcg_aware checks in the list_lru code. The test in list_lru_memcg_aware is broken: it assumes node 0 is always present, but it is not true on some systems as can be seen above. So fix this by avoiding checks on node 0. Remember the memcg-awareness by a bool flag in struct list_lru.

2019-06-01mm, memcg: consider subtrees in memory.eventsChris Down
memory.stat and other files already consider subtrees in their output, and we should too in order to not present an inconsistent interface. The current situation is fairly confusing, because people interacting with cgroups expect hierarchical behaviour in the vein of memory.stat, cgroup.events, and other files. For example, this causes confusion when debugging reclaim events under low, as currently these always read "0" at non-leaf memcg nodes, which frequently causes people to misdiagnose breach behaviour. The same confusion applies to other counters in this file when debugging issues. Aggregation is done at write time instead of at read-time since these counters aren't hot (unlike memory.stat which is per-page, so it does it at read time), and it makes sense to bundle this with the file notifications. After this patch, events are propagated up the hierarchy: [root@ktst ~]# cat /sys/fs/cgroup/system.slice/memory.events low 0 high 0 max 0 oom 0 oom_kill 0 [root@ktst ~]# systemd-run -p MemoryMax=1 true Running as unit: run-r251162a189fb4562b9dabfdc9b0422f5.service [root@ktst ~]# cat /sys/fs/cgroup/system.slice/memory.events low 0 high 0 max 7 oom 1 oom_kill 1 As this is a change in behaviour, this can be reverted to the old behaviour by mounting with the `memory_localevents' flag set. However, we use the new behaviour by default as there's a lack of evidence that there are any current users of memory.events that would find this change undesirable. akpm: this is a behaviour change, so Cc:stable. THis is so that forthcoming distros which use cgroup v2 are more likely to pick up the revised behaviour.

2019-06-01prctl_set_mm: downgrade mmap_sem to read lockMichal Koutný
The commit a3b609ef9f8b ("proc read mm's {arg,env}_{start,end} with mmap semaphore taken.") added synchronization of reading argument/environment boundaries under mmap_sem. Later commit 88aa7cc688d4 ("mm: introduce arg_lock to protect arg_start|end and env_start|end in mm_struct") avoided the coarse use of mmap_sem in similar situations. But there still remained two places that (mis)use mmap_sem. get_cmdline should also use arg_lock instead of mmap_sem when it reads the boundaries. The second place that should use arg_lock is in prctl_set_mm. By protecting the boundaries fields with the arg_lock, we can downgrade mmap_sem to reader lock (analogous to what we already do in prctl_set_mm_map).

2019-06-01treewide: fix typos of SPDX-License-IdentifierMasahiro Yamada
Prior to the adoption of SPDX, it was difficult for tools to determine the correct license due to incomplete or badly formatted license text. The SPDX solves this issue, assuming people can correctly spell "SPDX-License-Identifier" although this assumption is broken in some places. Since scripts/spdxcheck.py parses only lines that exactly matches to the correct tag, it cannot (should not) detect this kind of error. If the correct tag is missing, scripts/checkpatch.pl warns like this: WARNING: Missing or malformed SPDX-License-Identifier tag in line * So, people should notice it before the patch submission, but in reality broken tags sometimes slip in. The checkpatch warning is not useful for checking the committed files globally since large number of files still have no SPDX tag. Also, I am not sure about the legal effect when the SPDX tag is broken. Anyway, these typos are absolutely worth fixing. It is pretty easy to find suspicious lines by grep. $ git grep --not -e SPDX-License-Identifier --and -e SPDX- -- \ :^LICENSES :^scripts/spdxcheck.py :^*/license-rules.rst arch/arm/kernel/bugs.c:// SPDX-Identifier: GPL-2.0 drivers/phy/st/phy-stm32-usbphyc.c:// SPDX-Licence-Identifier: GPL-2.0 drivers/pinctrl/sh-pfc/pfc-r8a77980.c:// SPDX-Lincense-Identifier: GPL 2.0 lib/test_stackinit.c:// SPDX-Licenses: GPLv2 sound/soc/codecs/max9759.c:// SPDX-Licence-Identifier: GPL-2.0 Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
