MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
There is a TM Bad Thing bug that can be caused when you return from a
signal context in a suspended transaction but with ucontext MSR[TS] unset.
This forces regs->msr[TS] to be set at syscall entrance (since the CPU
state is transactional). It also calls treclaim() to flush the transaction
state, which is done based on the live (mfmsr) MSR state.
Since user context MSR[TS] is not set, then restore_tm_sigcontexts() is not
called, thus, not executing recheckpoint, keeping the CPU state as not
transactional. When calling rfid, SRR1 will have MSR[TS] set, but the CPU
state is non transactional, causing the TM Bad Thing with the following

Subject: [PATCH] powerpc/tm: Set MSR[TS] just prior to recheckpoint
On a signal handler return, the user could set a context with MSR[TS] bits
set, and these bits would be copied to task regs->msr.
At restore_tm_sigcontexts(), after current task regs->msr[TS] bits are set,
several __get_user() are called and then a recheckpoint is executed.
This is a problem since a page fault (in kernel space) could happen when
calling __get_user(). If it happens, the process MSR[TS] bits were
already set, but recheckpoint was not executed, and SPRs are still invalid.
The page fault can cause the current process to be de-scheduled, with
MSR[TS] active and without tm_recheckpoint() being called. More
importantly, without TEXASR[FS] bit set also.
Since TEXASR might not have the FS bit set, and when the process is
scheduled back, it will try to reclaim, which will be aborted because of
the CPU is not in the suspended state, and, then, recheckpoint. This
recheckpoint will restore thread->texasr into TEXASR SPR, which might be
zero, hitting a BUG_ON().

This patch simply delays the MSR[TS] set, so, if there is any page fault in
the __get_user() section, it does not have regs->msr[TS] set, since the TM
structures are still invalid, thus avoiding doing TM operations for
in-kernel exceptions and possible process reschedule.
With this patch, the MSR[TS] will only be set just before recheckpointing
and setting TEXASR[FS] = 1, thus avoiding an interrupt with TM registers in
invalid state.
Other than that, if CONFIG_PREEMPT is set, there might be a preemption just
after setting MSR[TS] and before tm_recheckpoint(), thus, this block must
be atomic from a preemption perspective, thus, calling
preempt_disable/enable() on this code.
It is not possible to move tm_recheckpoint to happen earlier, because it is
required to get the checkpointed registers from userspace, with
__get_user(), thus, the only way to avoid this undesired behavior is
delaying the MSR[TS] set.
The 32-bits signal handler seems to be safe this current issue, but, it
might be exposed to the preemption issue, thus, disabling preemption in
this chunk of code.
Changes from v2:
* Run the critical section with preempt_disable.

Subject: [PATCH] Btrfs: send, fix race with transaction commits that create
snapshots
If we create a snapshot of a snapshot currently being used by a send
operation, we can end up with send failing unexpectedly (returning
-ENOENT error to user space for example). The following diagram shows
how this happens.
CPU 1 CPU2 CPU3
btrfs_ioctl_send()
(...)
create_snapshot()
-> creates snapshot of a
root used by the send
task
btrfs_commit_transaction()
create_pending_snapshot()
__get_inode_info()
btrfs_search_slot()
btrfs_search_slot_get_root()
down_read commit_root_sem
get reference on eb of the
commit root
-> eb with bytenr == X
up_read commit_root_sem
btrfs_cow_block(root node)
btrfs_free_tree_block()
-> creates delayed ref to
free the extent
btrfs_run_delayed_refs()
-> runs the delayed ref,
adds extent to
fs_info->pinned_extents
btrfs_finish_extent_commit()
unpin_extent_range()
-> marks extent as free
in the free space cache
transaction commit finishes

btrfs_alloc_tree_block()
btrfs_reserve_extent()
-> allocates extent at
bytenr == X
btrfs_init_new_buffer(bytenr X)
btrfs_find_create_tree_block()
alloc_extent_buffer(bytenr X)
find_extent_buffer(bytenr X)
-> returns existing eb,
which the send task got
(...)
-> modifies content of the
eb with bytenr == X
-> uses an eb that now
belongs to some other
tree and no more matches
the commit root of the
snapshot, resuts will be
unpredictable
The consequences of this race can be various, and can lead to searches in
the commit root performed by the send task failing unexpectedly (unable to
find inode items, returning -ENOENT to user space, for example) or not
failing because an inode item with the same number was added to the tree
that reused the metadata extent, in which case send can behave incorrectly
in the worst case or just fail later for some reason.
Fix this by performing a copy of the commit root's extent buffer when doing
a search in the context of a send operation.

This happens because during page writeback it's valid for
writepage_delalloc to instantiate a delalloc range which doesn't belong
to the page currently being written back.
The reason this case is valid is due to find_lock_delalloc_range
returning any available range after the passed delalloc_start and
ignoring whether the page under writeback is within that range.
In turn ordered extents (OE) are always created for the returned range
from find_lock_delalloc_range. If, however, a failure occurs while OE
are being created then the clean up code in btrfs_cleanup_ordered_extents
will be called.
Unfortunately the code in btrfs_cleanup_ordered_extents doesn't consider
the case of such 'foreign' range being processed and instead it always
assumes that the range OE are created for belongs to the page. This
leads to the first page of such foregin range to not be cleaned up since
it's deliberately missed and skipped by the current cleaning up code.
Fix this by correctly checking whether the current page belongs to the
range being instantiated and if so adjsut the range parameters passed
for cleaning up. If it doesn't, then just clean the whole OE range
directly.

This happens because during page writeback it's valid for
writepage_delalloc to instantiate a delalloc range which doesn't belong
to the page currently being written back.
The reason this case is valid is due to find_lock_delalloc_range
returning any available range after the passed delalloc_start and
ignoring whether the page under writeback is within that range.
In turn ordered extents (OE) are always created for the returned range
from find_lock_delalloc_range. If, however, a failure occurs while OE
are being created then the clean up code in btrfs_cleanup_ordered_extents
will be called.
Unfortunately the code in btrfs_cleanup_ordered_extents doesn't consider
the case of such 'foreign' range being processed and instead it always
assumes that the range OE are created for belongs to the page. This
leads to the first page of such foregin range to not be cleaned up since
it's deliberately missed and skipped by the current cleaning up code.
Fix this by correctly checking whether the current page belongs to the
range being instantiated and if so adjsut the range parameters passed
for cleaning up. If it doesn't, then just clean the whole OE range
directly.

Subject: [PATCH] Btrfs: fix deadlock with memory reclaim during scrub
When a transaction commit starts, it attempts to pause scrub and it blocks
until the scrub is paused. So while the transaction is blocked waiting for
scrub to pause, we can not do memory allocation with GFP_KERNEL from scrub,
otherwise we risk getting into a deadlock with reclaim.
Checking for scrub pause requests is done early at the beginning of the
while loop of scrub_stripe() and later in the loop, scrub_extent() and
scrub_raid56_parity() are called, which in turn call scrub_pages() and
scrub_pages_for_parity() respectively. These last two functions do memory
allocations using GFP_KERNEL. Same problem could happen while scrubbing
the super blocks, since it calls scrub_pages().
We also can not have any of the worker tasks, created by the scrub task,
doing GFP_KERNEL allocations, because before pausing, the scrub task waits
for all the worker tasks to complete (also done at scrub_stripe()).
So make sure GFP_NOFS is used for the memory allocations because at any
time a scrub pause request can happen from another task that started to
commit a transaction.

Subject: [PATCH] btrfs: dev-replace: go back to suspended state if target
device is missing
At the time of forced unmount we place the running replace to
BTRFS_IOCTL_DEV_REPLACE_STATE_SUSPENDED state, so when the system comes
back and expect the target device is missing.
Then let the replace state continue to be in
BTRFS_IOCTL_DEV_REPLACE_STATE_SUSPENDED state instead of
BTRFS_IOCTL_DEV_REPLACE_STATE_STARTED as there isn't any matching scrub
running as part of replace.

Subject: [PATCH] btrfs: dev-replace: go back to suspended state if target
device is missing
At the time of forced unmount we place the running replace to
BTRFS_IOCTL_DEV_REPLACE_STATE_SUSPENDED state, so when the system comes
back and expect the target device is missing.
Then let the replace state continue to be in
BTRFS_IOCTL_DEV_REPLACE_STATE_SUSPENDED state instead of
BTRFS_IOCTL_DEV_REPLACE_STATE_STARTED as there isn't any matching scrub
running as part of replace.
Fixes: e93c89c1aaaa ("Btrfs: add new sources for device replace code")

Subject: [PATCH] clk: sunxi-ng: Use u64 for calculation of NM rate
Allwinner H6 SoC has multiplier N range between 1 and 254. Since parent
rate is 24MHz, intermediate result when calculating final rate easily
overflows 32 bit variable.
Because of that, introduce function for calculating clock rate which
uses 64 bit variable for intermediate result.
Fixes: 6174a1e24b0d ("clk: sunxi-ng: Add N-M-factor clock support")
Fixes: ee28648cb2b4 ("clk: sunxi-ng: Remove the use of rational computations")

If we receive a file handle, either from NFS or open_by_handle_at(2),
and it points at an inode which has not been initialized, and the file
system has metadata checksums enabled, we shouldn't try to get the
inode, discover the checksum is invalid, and then declare the file
system as being inconsistent.
This can be reproduced by creating a test file system via "mke2fs -t
ext4 -O metadata_csum /tmp/foo.img 8M", mounting it, cd'ing into that
directory, and then running the following program.
#define _GNU_SOURCE

Subject: [PATCH] ext4: avoid declaring fs inconsistent due to invalid file
handles
If we receive a file handle, either from NFS or open_by_handle_at(2),
and it points at an inode which has not been initialized, and the file
system has metadata checksums enabled, we shouldn't try to get the
inode, discover the checksum is invalid, and then declare the file
system as being inconsistent.
This can be reproduced by creating a test file system via "mke2fs -t
ext4 -O metadata_csum /tmp/foo.img 8M", mounting it, cd'ing into that
directory, and then running the following program.
#define _GNU_SOURCE
#include <fcntl.h>
struct handle {
struct file_handle fh;
unsigned char fid[MAX_HANDLE_SZ];
};
int main(int argc, char **argv)
{
struct handle h = {{8, 1 }, { 12, }};
open_by_handle_at(AT_FDCWD, &h.fh, O_RDONLY);
return 0;
}

Subject: [PATCH] ext4: add ext4_sb_bread() to disambiguate ENOMEM cases
Today, when sb_bread() returns NULL, this can either be because of an
I/O error or because the system failed to allocate the buffer. Since
it's an old interface, changing would require changing many call
sites.
So instead we create our own ext4_sb_bread(), which also allows us to
set the REQ_META flag.
Also fixed a problem in the xattr code where a NULL return in a
function could also mean that the xattr was not found, which could
lead to the wrong error getting returned to userspace.
Fixes: ac27a0ec112a ("ext4: initial copy of files from ext3")

Subject: [PATCH] ext4: add ext4_sb_bread() to disambiguate ENOMEM cases
Today, when sb_bread() returns NULL, this can either be because of an
I/O error or because the system failed to allocate the buffer. Since
it's an old interface, changing would require changing many call
sites.
So instead we create our own ext4_sb_bread(), which also allows us to
set the REQ_META flag.
Also fixed a problem in the xattr code where a NULL return in a
function could also mean that the xattr was not found, which could
lead to the wrong error getting returned to userspace.
Fixes: ac27a0ec112a ("ext4: initial copy of files from ext3")

Subject: [PATCH] KVM: PPC: Book3S HV: Fix race between kvm_unmap_hva_range and
MMU mode switch
Testing has revealed an occasional crash which appears to be caused
by a race between kvmppc_switch_mmu_to_hpt and kvm_unmap_hva_range_hv.
The symptom is a NULL pointer dereference in __find_linux_pte() called
from kvm_unmap_radix() with kvm->arch.pgtable == NULL.
Looking at kvmppc_switch_mmu_to_hpt(), it does indeed clear
kvm->arch.pgtable (via kvmppc_free_radix()) before setting
kvm->arch.radix to NULL, and there is nothing to prevent
kvm_unmap_hva_range_hv() or the other MMU callback functions from
being called concurrently with kvmppc_switch_mmu_to_hpt() or
kvmppc_switch_mmu_to_radix().
This patch therefore adds calls to spin_lock/unlock on the kvm->mmu_lock
around the assignments to kvm->arch.radix, and makes sure that the
partition-scoped radix tree or HPT is only freed after changing
kvm->arch.radix.
This also takes the kvm->mmu_lock in kvmppc_rmap_reset() to make sure
that the clearing of each rmap array (one per memslot) doesn't happen
concurrently with use of the array in the kvm_unmap_hva_range_hv()
or the other MMU callbacks.
Fixes: 18c3640cefc7 ("KVM: PPC: Book3S HV: Add infrastructure for running HPT guests on radix host")

Subject: [PATCH] x86/speculation/l1tf: Drop the swap storage limit restriction
when l1tf=off
Swap storage is restricted to max_swapfile_size (~16TB on x86_64) whenever
the system is deemed affected by L1TF vulnerability. Even though the limit
is quite high for most deployments it seems to be too restrictive for
deployments which are willing to live with the mitigation disabled.
We have a customer to deploy 8x 6,4TB PCIe/NVMe SSD swap devices which is
clearly out of the limit.
Drop the swap restriction when l1tf=off is specified. It also doesn't make
much sense to warn about too much memory for the l1tf mitigation when it is
forcefully disabled by the administrator.
[ tglx: Folded the documentation delta change ]

Subject: [PATCH] x86/speculation/l1tf: Drop the swap storage limit restriction
when l1tf=off
Swap storage is restricted to max_swapfile_size (~16TB on x86_64) whenever
the system is deemed affected by L1TF vulnerability. Even though the limit
is quite high for most deployments it seems to be too restrictive for
deployments which are willing to live with the mitigation disabled.
We have a customer to deploy 8x 6,4TB PCIe/NVMe SSD swap devices which is
clearly out of the limit.
Drop the swap restriction when l1tf=off is specified. It also doesn't make
much sense to warn about too much memory for the l1tf mitigation when it is
forcefully disabled by the administrator.
[ tglx: Folded the documentation delta change ]

[v4.9, v4.14] qmi_wwan: apply SET_DTR quirk to the SIMCOM shared device ID
by Bjørn Mork
Hello!
Please apply commit 102cd9096356 ("qmi_wwan: apply SET_DTR quirk to the
SIMCOM shared device ID") to the v4.9 and v4.14 longterm branches.
Note: There is no point in backporting it to earlier releases, as the
affected devices need the "raw-ip" feature introduced in v4.5.
Thanks,
Bjørn

Subject: [PATCH] ASoC: intel: cht_bsw_max98090_ti: Add pmc_plt_clk_0 quirk for
Chromebook Gnawty
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The Gnawty model Chromebook uses pmc_plt_clk_0 instead of pmc_plt_clk_3
for the mclk, just like the Clapper and Swanky models.
This commit adds a DMI based quirk for this.
This fixing audio no longer working on these devices after
commit 648e921888ad ("clk: x86: Stop marking clocks as CLK_IS_CRITICAL")
that commit fixes us unnecessary keeping unused clocks on, but in case of
the Gnawty that was breaking audio support since we were not using the
right clock in the cht_bsw_max98090_ti machine driver.

The following will need to be applied to 4.19 and 4.20 first. Both had Cc stable:
fa4600734b74 ("crypto: cfb - fix decryption")
7da66670775d ("crypto: testmgr - add AES-CFB tests")
Herbert, why was CFB accepted without any test vectors in the first place?

------------------------------------------------------
From: Roman Penyaev <rpenyaev(a)suse.de>
Subject: mm/vmalloc: fix size check for remap_vmalloc_range_partial()
When VM_NO_GUARD is not set area->size includes adjacent guard page,
thus for correct size checking get_vm_area_size() should be used, but
not area->size.
This fixes possible kernel oops when userspace tries to mmap an area on
1 page bigger than was allocated by vmalloc_user() call: the size check
inside remap_vmalloc_range_partial() accounts non-existing guard page
also, so check successfully passes but vmalloc_to_page() returns NULL
(guard page does not physically exist).
The following code pattern example should trigger an oops:
static int oops_mmap(struct file *file, struct vm_area_struct *vma)
{
void *mem;
mem = vmalloc_user(4096);
BUG_ON(!mem);
/* Do not care about mem leak */
return remap_vmalloc_range(vma, mem, 0);
}
And userspace simply mmaps size + PAGE_SIZE:
mmap(NULL, 8192, PROT_WRITE|PROT_READ, MAP_PRIVATE, fd, 0);
Possible candidates for oops which do not have any explicit size
checks:
*** drivers/media/usb/stkwebcam/stk-webcam.c:
v4l_stk_mmap[789] ret = remap_vmalloc_range(vma, sbuf->buffer, 0);
Or the following one:
*** drivers/video/fbdev/core/fbmem.c
static int
fb_mmap(struct file *file, struct vm_area_struct * vma)
...
res = fb->fb_mmap(info, vma);
Where fb_mmap callback calls remap_vmalloc_range() directly without any
explicit checks:
*** drivers/video/fbdev/vfb.c
static int vfb_mmap(struct fb_info *info,
struct vm_area_struct *vma)
{
return remap_vmalloc_range(vma, (void *)info->fix.smem_start, vma->vm_pgoff);
}

------------------------------------------------------
From: Jan Stancek <jstancek(a)redhat.com>
Subject: mm: page_mapped: don't assume compound page is huge or THP
LTP proc01 testcase has been observed to rarely trigger crashes
on arm64:
page_mapped+0x78/0xb4
stable_page_flags+0x27c/0x338
kpageflags_read+0xfc/0x164
proc_reg_read+0x7c/0xb8
__vfs_read+0x58/0x178
vfs_read+0x90/0x14c
SyS_read+0x60/0xc0
Issue is that page_mapped() assumes that if compound page is not huge,
then it must be THP. But if this is 'normal' compound page
(COMPOUND_PAGE_DTOR), then following loop can keep running (for
HPAGE_PMD_NR iterations) until it tries to read from memory that isn't
mapped and triggers a panic:
for (i = 0; i < hpage_nr_pages(page); i++) {
if (atomic_read(&page[i]._mapcount) >= 0)
return true;
}
I could replicate this on x86 (v4.20-rc4-98-g60b548237fed) only
with a custom kernel module [1] which:
- allocates compound page (PAGEC) of order 1
- allocates 2 normal pages (COPY), which are initialized to 0xff
(to satisfy _mapcount >= 0)
- 2 PAGEC page structs are copied to address of first COPY page
- second page of COPY is marked as not present
- call to page_mapped(COPY) now triggers fault on access to 2nd
COPY page at offset 0x30 (_mapcount)
[1] https://github.com/jstancek/reproducers/blob/master/kernel/page_mapped_cras…
Fix the loop to iterate for "1 << compound_order" pages.
Kirrill said "IIRC, sound subsystem can producuce custom mapped compound
pages".

[PATCH] fork, memcg: fix cached_stacks case
by Shakeel Butt
Commit 5eed6f1dff87 ("fork,memcg: fix crash in free_thread_stack on
memcg charge fail") fixes a crash caused due to failed memcg charge of
the kernel stack. However the fix misses the cached_stacks case which
this patch fixes. So, the same crash can happen if the memcg charge of
a cached stack is failed.

[PATCH 04/16] crypto: pcbc - remove bogus memcpy()s with src == dest
by Eric Biggers
From: Eric Biggers <ebiggers(a)google.com>
The memcpy()s in the PCBC implementation use walk->iv as both the source
and destination, which has undefined behavior. These memcpy()'s are
actually unneeded, because walk->iv is already used to hold the previous
plaintext block XOR'd with the previous ciphertext block. Thus,
walk->iv is already updated to its final value.
So remove the broken and unnecessary memcpy()s.

[PATCH v2] can: gw: ensure DLC boundaries after CAN frame modification
by Marc Kleine-Budde
From: Oliver Hartkopp <socketcan(a)hartkopp.net>
Muyu Yu provided a POC where user root with CAP_NET_ADMIN can create a CAN
frame modification rule that makes the data length code a higher value than
the available CAN frame data size. In combination with a configured checksum
calculation where the result is stored relatively to the end of the data
(e.g. cgw_csum_xor_rel) the tail of the skb (e.g. frag_list pointer in
skb_shared_info) can be rewritten which finally can cause a system crash.
Michael Kubecek suggested to drop frames that have a DLC exceeding the
available space after the modification process and provided a patch that can
handle CAN FD frames too. Within this patch we also limit the length for the
checksum calculations to the maximum of Classic CAN data length (8).
CAN frames that are dropped by these additional checks are counted with the
CGW_DELETED counter which indicates misconfigurations in can-gw rules.
This fixes CVE-2019-3701.

[PATCH 1/3] arm64: compat: Avoid sending SIGILL for unallocated syscall numbers
by Will Deacon
The ARM Linux kernel handles the EABI syscall numbers as follows:
0 - NR_SYSCALLS-1 : Invoke syscall via syscall table
NR_SYSCALLS - 0xeffff : -ENOSYS (to be allocated in future)
0xf0000 - 0xf07ff : Private syscall or -ENOSYS if not allocated
> 0xf07ff : SIGILL
Our compat code gets this wrong and ends up sending SIGILL in response
to all syscalls greater than NR_SYSCALLS which have a value greater
than 0x7ff in the bottom 16 bits.
Fix this by defining the end of the ARM private syscall region and
checking the syscall number against that directly. Update the comment
while we're at it.

[PATCH 2/3] arm64: compat: Don't pull syscall number from regs in arm_compat_syscall
by Will Deacon
The syscall number may have been changed by a tracer, so we should pass
the actual number in from the caller instead of pulling it from the
saved r7 value directly.

[PATCH] can: gw: ensure DLC boundaries after CAN frame modification
by Oliver Hartkopp
The CAN frame modification rules allow bitwise logical operations which can
be also applied to the can_dlc field. Ensure the manipulation result to
maintain the can_dlc boundaries so that the CAN drivers do not accidently
write arbitrary content beyond the data registers in the CAN controllers
I/O mem when processing can-gw manipulated outgoing frames. When passing these
frames to user space this issue did not have any effect to the kernel or any
leaked data as we always strictly copy sizeof(struct can_frame) bytes.

[PATCH] drivers/perf: hisi: Fixup one DDRC PMU register offset
by Shaokun Zhang
For DDRC PMU, each PMU counter is fixed-purpose. There is a mismatch
between perf list and driver definition on rw_chg event.
# perf list | grep chg
hisi_sccl1_ddrc0/rnk_chg/ [Kernel PMU event]
hisi_sccl1_ddrc0/rw_chg/ [Kernel PMU event]
But the register offset of rw_chg event is not defined in the driver,
meanwhile bnk_chg register offset is mis-defined, let's fixup it.

[PATCH v3 1/1] scsi: Synchronize request queue PM status only on successful resume
by stanley.chu＠mediatek.com
From: Stanley Chu <stanley.chu(a)mediatek.com>
The commit 356fd2663cff ("scsi: Set request queue runtime PM status
back to active on resume") fixed up the inconsistent RPM status between
request queue and device. However changing request queue RPM status
shall be done only on successful resume, otherwise status may be still
inconsistent as below,
Request queue: RPM_ACTIVE
Device: RPM_SUSPENDED
This ends up soft lockup because requests can be submitted to
underlying devices but those devices and their required resource
are not resumed.
For example,
After above inconsistent status happens, IO request can be submitted
to UFS device driver but required resource (like clock) is not resumed
yet thus lead to warning as below call stack,
WARN_ON(hba->clk_gating.state != CLKS_ON);
ufshcd_queuecommand
scsi_dispatch_cmd
scsi_request_fn
__blk_run_queue
cfq_insert_request
__elv_add_request
blk_flush_plug_list
blk_finish_plug
jbd2_journal_commit_transaction
kjournald2
We may see all behind IO requests hang because of no response from
storage host or device and then soft lockup happens in system. In the
end, system may crash in many ways.

[PATCH 02/16] crypto: cfb - remove bogus memcpy() with src == dest
by Eric Biggers
From: Eric Biggers <ebiggers(a)google.com>
The memcpy() in crypto_cfb_decrypt_inplace() uses walk->iv as both the
source and destination, which has undefined behavior. It is unneeded
because walk->iv is already used to hold the previous ciphertext block;
thus, walk->iv is already updated to its final value. So, remove it.
Also, note that in-place decryption is the only case where the previous
ciphertext block is not directly available. Therefore, as a related
cleanup I also updated crypto_cfb_encrypt_segment() to directly use the
previous ciphertext block rather than save it into walk->iv. This makes
it consistent with in-place encryption and out-of-place decryption; now
only in-place decryption is different, because it has to be.

[PATCH 01/16] crypto: cfb - add missing 'chunksize' property
by Eric Biggers
From: Eric Biggers <ebiggers(a)google.com>
Like some other block cipher mode implementations, the CFB
implementation assumes that while walking through the scatterlist, a
partial block does not occur until the end. But the walk is incorrectly
being done with a blocksize of 1, as 'cra_blocksize' is set to 1 (since
CFB is a stream cipher) but no 'chunksize' is set. This bug causes
incorrect encryption/decryption for some scatterlist layouts.
Fix it by setting the 'chunksize'. Also extend the CFB test vectors to
cover this bug as well as cases where the message length is not a
multiple of the block size.

[PATCH] drm/amd/display: Fix unintialized max_bpc state values
by Alex Deucher
From: Nicholas Kazlauskas <nicholas.kazlauskas(a)amd.com>
[Why]
If the "max bpc" isn't explicitly set in the atomic state then it
have a value of 0. This has the correct behavior of limiting a panel
to 8bpc in the case where the panel supports 8bpc. In the case of eDP
panels this isn't a true assumption - there are panels that can only
do 6bpc.
Banding occurs for these displays.
[How]
Initialize the max_bpc when the connector resets to 8bpc. Also carry
over the value when the state is duplicated.
Bugzilla: https://bugs.freedesktop.org/108825
Fixes: 307638884f72 ("drm/amd/display: Support amdgpu "max bpc" connector property")
Backport of commit 49f1c44b581b08e3289127ffe58bd208c3166701 upstream.

The 4.9 version of arch_dup_mmap() does not contain the
ldt_dup_context() line. We just need to add arch_dup_pkeys(), like so:
void arch_dup_mmap(struct mm_struct *oldmm,
struct mm_struct *mm)
{
+ arch_dup_pkeys(oldmm, mm);
paravirt_arch_dup_mmap(oldmm, mm);
}
Should be a pretty simple merge. We can basically ignore the
ldt_dup_context() changes.

[PATCH v2] nvmet-rdma: fix null dereference under heavy load
by Raju Rangoju
Under heavy load if we don't have any pre-allocated rsps left, we
dynamically allocate a rsp, but we are not actually allocating memory
for nvme_completion (rsp->req.rsp). In such a case, accessing pointer
fields (req->rsp->status) in nvmet_req_init() will result in crash.
To fix this, allocate the memory for nvme_completion by calling
nvmet_rdma_alloc_rsp()
Fixes: 8407879c("nvmet-rdma:fix possible bogus dereference under heavy load")

From: Qian Cai <cai(a)lca.pw>
Subject: mm/usercopy.c: no check page span for stack objects
It is easy to trigger this with CONFIG_HARDENED_USERCOPY_PAGESPAN=y,
usercopy: Kernel memory overwrite attempt detected to spans multiple
pages (offset 0, size 23)!
kernel BUG at mm/usercopy.c:102!
For example,
print_worker_info
char name[WQ_NAME_LEN] = { };
char desc[WORKER_DESC_LEN] = { };
probe_kernel_read(name, wq->name, sizeof(name) - 1);
probe_kernel_read(desc, worker->desc, sizeof(desc) - 1);
__copy_from_user_inatomic
check_object_size
check_heap_object
check_page_span
This is because on-stack variables could cross PAGE_SIZE boundary, and
failed this check,
if (likely(((unsigned long)ptr & (unsigned long)PAGE_MASK) ==
((unsigned long)end & (unsigned long)PAGE_MASK)))
ptr = FFFF889007D7EFF8
end = FFFF889007D7F00E
Hence, fix it by checking if it is a stack object first.

[PATCH v3.16 2/2] v4l: event: Add subscription to list before calling "add" operation
by Sakari Ailus
[ upstream commit 92539d3eda2c090b382699bbb896d4b54e9bdece ]
Patch ad608fbcf166 changed how events were subscribed to address an issue
elsewhere. As a side effect of that change, the "add" callback was called
before the event subscription was added to the list of subscribed events,
causing the first event queued by the add callback (and possibly other
events arriving soon afterwards) to be lost.
Fix this by adding the subscription to the list before calling the "add"
callback, and clean up afterwards if that fails.
Fixes: ad608fbcf166 ("media: v4l: event: Prevent freeing event subscriptions while accessed")

[PATCH 0/4] [3.16.y] thp03 LTP test panic the kernel after applying the l1tf patches
by Wenkuan Wang
For stable tree 3.16.y, as regarding the page set into PAGE_NONE, the PFN will be inverted,
when reference it by pmd_page, it needs to be inverted again controlling by
protnone_mask(pfn).
https://github.com/linux-test-project/ltp/blob/master/testcases/kernel/mem/…
This LTP test case thp03 will get the kernel OOPS like bellow, and
it could be reproduced every time.

[PATCH] ACPI / power: Skip duplicate power-resources in PR tables
by Hans de Goede
Some ACPI tables contain duplicate resources like this:
Name (_PR0, Package (0x04) // _PR0: Power Resources for D0
{
P28P,
P18P,
P18P,
CLK4
})
This causes a WARN_ON in sysfs_add_link_to_group because we end up
adding a link to the same acpi_device twice:
sysfs: cannot create duplicate filename '/devices/LNXSYSTM:00/LNXSYBUS:00/PNP0A08:00/808622C1:00/OVTI2680:00/power_resources_D0/LNXPOWER:0a'

[regression] USB power management failure to suspend / high CPU usage
by Eric Blau
Hi folks,
I noticed a regression introduced sometime after 4.19.4 in USB power
management. I have a 2015 MacBook Pro. When I try to do a suspend or a
suspend+hibernate, I get the following error messages trying to
suspend usb2 and the suspend fails. This works fine in 4.19.4:
Dec 22 13:50:36 eric-macbookpro kernel: Freezing remaining freezable
tasks ... (elapsed 0.001 seconds) done.
Dec 22 13:50:36 eric-macbookpro kernel: Suspending console(s) (use
no_console_suspend to debug)
Dec 22 13:50:36 eric-macbookpro kernel: dpm_run_callback():
usb_dev_freeze+0x0/0x10 returns -16
Dec 22 13:50:36 eric-macbookpro kernel: PM: Device usb2 failed to
freeze async: error -16
Dec 22 13:50:38 eric-macbookpro systemd[1]:
systemd-hybrid-sleep.service: Main process exited, code=exited,
status=1/FAILURE
Dec 22 13:50:38 eric-macbookpro systemd[1]:
systemd-hybrid-sleep.service: Failed with result 'exit-code'.
Dec 22 13:50:38 eric-macbookpro systemd[1]: Failed to start Hybrid
Suspend+Hibernate.
Dec 22 13:50:38 eric-macbookpro systemd[1]: Dependency failed for
Hybrid Suspend+Hibernate.
Dec 22 13:50:38 eric-macbookpro systemd[1]: hybrid-sleep.target: Job
hybrid-sleep.target/start failed with result 'dependency'.
Dec 22 13:50:38 eric-macbookpro systemd-logind[1573]: Operation
'sleep' finished.
Dec 22 13:50:38 eric-macbookpro systemd[1]: Stopped target Sleep.
The behavior exists in 4.19.8 and 4.19.11, the kernel versions I have
upgraded to with Arch Linux, so the regression was introduced sometime
between 4.19.4 and 4.19.8. Hibernate still works but when I resume
from hibernate, there is a ksoftirqd and kworker thread/process
together taking up 100% of one core. If I turn off auto power control
for usb1 and usb2, the threads stop spinning. i.e.,
echo 'on' > '/sys/bus/usb/devices/usb1/power/control
Any suggestions as to where this regression was introduced and what
can be done to fix it?
Thanks,
Eric

[PATCH v2 1/1] scsi: Synchronize request queue PM status only on successful resume
by stanley.chu＠mediatek.com
From: Stanley Chu <stanley.chu(a)mediatek.com>
The commit 356fd2663cff ("scsi: Set request queue runtime PM status
back to active on resume") fixed up the inconsistent RPM status between
request queue and device. However changing request queue RPM status
shall be done only on successful resume, otherwise status may be still
inconsistent as below,
Request queue: RPM_ACTIVE
Device: RPM_SUSPENDED
This ends up soft lockup because requests can be submitted to
underlying devices but those devices and their required resource
are not resumed.

[PATCH 2/2] staging: rtl8188eu: Fix module loading from tasklet for WEP encryption
by Larry Finger
Commit 2b2ea09e74a5 ("staging:r8188eu: Use lib80211 to decrypt WEP-frames")
causes scheduling while atomic bugs followed by a hard freeze whenever
the driver tries to connect to a WEP-encrypted network. Experimentation
showed that the freezes were eliminated when module lib80211 was
preloaded, which can be forced by calling lib80211_get_crypto_ops()
directly rather than indirectly through try_then_request_module().
With this change, no BUG messages are logged.

[PATCH] x86/retpoline: change RETPOLINE into CONFIG_RETPOLINE
by Nadav Amit
A recent enhancement intentionally fails the kernel build if the
compiler does not support retpolines and CONFIG_RETPOLINE is set.
However, the patch that introduced it did not change RETPOLINE macro
references into CONFIG_RETPOLINE ones. As a result, indirect branches
that are used by init functions are not kept (i.e., they use
retpolines), and modules that do not use retpolines are marked as
retpoline-safe.
Fix it be changing RETPOLINE into CONFIG_RETPOLINE.

[PATCH v2] netfilter: xt_connlimit: fix race in connection counting
by Alakesh Haloi
An iptable rule like the following on a multicore systems will result in
accepting more connections than set in the rule.
iptables -A INPUT -p tcp -m tcp --syn --dport 7777 -m connlimit \
--connlimit-above 2000 --connlimit-mask 0 -j DROP
In check_hlist function, connections that are found in saved connections
but not in netfilter conntrack are deleted, assuming that those
connections do not exist anymore. But for multi core systems, there exists
a small time window, when a connection has been added to the xt_connlimit
maintained rb-tree but has not yet made to netfilter conntrack table. This
causes concurrent connections to return incorrect counts and go over limit
set in iptable rule.
The fix has been partially backported from the above mentioned upstream
commit. Introduce timestamp and the owning cpu.

In check_hlist() function
a. loop over saved connection.
1. call nf_conntrack_find_get()
2. If not found in 1.
i. call hlist_del()
[Connection 1 was in the

ii. connection 1 gets deleted

b. return total count to caller
c. connection 2 gets added to list

conntrack_table_len = N + 2
So we end up with N + 1 connections in the list but N + 2 in nf_conntrack,
allowing more number of connections eventually than set in the rule.
This fix adds an additional field to track such pending connections
and prevent them from being deleted by another execution thread on
a different core and returns correct count.

[PATCH 0/2] x86/mm/pkeys: fix user-visible pkey state destruction at fork()
by Dave Hansen
Hi x86 maintainers,
This is an important fix that I believe needs to be merged for 4.21.
Without it, applications calling fork() can potentially double-allocate
a protection key, causing lots of strange problems.
Thomas's Reviewed-by is on the the actual fix, but not the selftest.
I would also be happy to send this as a pull request if you would
prefer.

[PATCH 4.14 0/4] netfilter: xt_connlimit: backport upstream fixes for race in connection counting
by Mauricio Faria de Oliveira
Recently, Alakesh Haloi reported the following issue [1] with stable/4.14:
"""
An iptable rule like the following on a multicore systems will result in
accepting more connections than set in the rule.
iptables -A INPUT -p tcp -m tcp --syn --dport 7777 -m connlimit \
--connlimit-above 2000 --connlimit-mask 0 -j DROP
"""
And proposed a fix that is not in Linus's tree. The discussion went on to
confirm whether the issue was still reproducible with mainline/nf.git tip,
and to either identify the upstream fix or re-submit the non-upstream fix.
Alakesh eventually was able to test with upstream, and reported that issue
was still reproducible [2].
On that, our findinds diverge, at least in my test environment:
First, I verified that the suggested mainline fix for the issue [3] indeed
fixes it, by testing with it applied and reverted on v4.18, a clean revert.
(The issue is reproducible with the commit reverted).
Then, with a consistent reproducer, I moved to nf.git, with HEAD on commit
a007232 ("netfilter: nf_conncount: fix argument order to find_next_bit"),
and the issues was not reproducible (even with 20+ threads on client side,
the number Alakesh reported to achieve 2150+ connections [4], and I tried
spreading the network interface IRQ affinity over more and more CPUs too.)
Either way, the suggested mainline fix does actually fix the issue in 4.14
for at least one environment. So, it might well be the case that Alakesh's
test environment has differences/subtleties that leads to more connections
accepted, and more commits are needed for that particular environment type.
But for now, with one bare-metal environment (24-core server, 4-core client)
verified, I thought of submitting the patches for review/comments/testing,
then looking for additional fixes for that environment separately.
The fix is PATCH 4/4, and PATCHes 1-3/4 are helpers for a cleaner backport.
All backports are simple, and essentially consist of refresh context lines
and use older struct/file names.
Reviews from netfilter maintainers are very appreciated, as I've no previous
experience in this area, and although the backports look simple and build/run
correctly, there's usually stuff that only more experienced people may notice.
Thanks,
Mauricio

Subject: lib/gen_crc64table.c: don't depend on linux headers being installed
gen_crc64table requires linux include files to be installed in
/usr/include/linux. This is a new requrement so hosts that could
previously build the kernel, now cannot.
gen_crc64table makes this requirement by including <linux/swab.h>, but
nothing from that header is actually used.
So remove the #include, so that the linux headers no longer need to be
installed.

Burt Holzman has noticed that memcg v1 doesn't notify about OOM events via

out_of_memory back to the charge path") has moved the oom handling back to
the charge path. While doing so the notification was left behind in
mem_cgroup_oom_synchronize.
Fix the issue by replicating the oom hierarchy locking and the
notification.

Subject: mm, swap: fix swapoff with KSM pages
has been removed from the -mm tree. Its filename was
mm-swap-fix-swapoff-with-ksm-pages.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: Huang Ying <ying.huang(a)intel.com>
Subject: mm, swap: fix swapoff with KSM pages
KSM pages may be mapped to the multiple VMAs that cannot be reached from
one anon_vma. So during swapin, a new copy of the page need to be
generated if a different anon_vma is needed, please refer to comments of
ksm_might_need_to_copy() for details.
During swapoff, unuse_vma() uses anon_vma (if available) to locate VMA and
virtual address mapped to the page, so not all mappings to a swapped out
KSM page could be found. So in try_to_unuse(), even if the swap count of
a swap entry isn't zero, the page needs to be deleted from swap cache, so
that, in the next round a new page could be allocated and swapin for the
other mappings of the swapped out KSM page.
But this contradicts with the THP swap support. Where the THP could be
deleted from swap cache only after the swap count of every swap entry in
the huge swap cluster backing the THP has reach 0. So try_to_unuse() is
changed in commit e07098294adf ("mm, THP, swap: support to reclaim swap
space for THP swapped out") to check that before delete a page from swap
cache, but this has broken KSM swapoff too.
Fortunately, KSM is for the normal pages only, so the original behavior
for KSM pages could be restored easily via checking PageTransCompound().
That is how this patch works.
The bug is introduced by e07098294adf ("mm, THP, swap: support to reclaim
swap space for THP swapped out"), which is merged by v4.14-rc1. So I
think we should backport the fix to from 4.14 on. But Hugh thinks it may
be rare for the KSM pages being in the swap device when swapoff, so nobody
reports the bug so far.

hugetlbfs-use-i_mmap_rwsem-to-fix-page-fault-truncate-race.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: Mike Kravetz <mike.kravetz(a)oracle.com>
Subject: hugetlbfs: Use i_mmap_rwsem to fix page fault/truncate race
hugetlbfs page faults can race with truncate and hole punch operations.
Current code in the page fault path attempts to handle this by 'backing
out' operations if we encounter the race. One obvious omission in the
current code is removing a page newly added to the page cache. This is
pretty straight forward to address, but there is a more subtle and
difficult issue of backing out hugetlb reservations. To handle this
correctly, the 'reservation state' before page allocation needs to be
noted so that it can be properly backed out. There are four distinct
possibilities for reservation state: shared/reserved, shared/no-resv,
private/reserved and private/no-resv. Backing out a reservation may
require memory allocation which could fail so that needs to be taken into
account as well.
Instead of writing the required complicated code for this rare occurrence,
just eliminate the race. i_mmap_rwsem is now held in read mode for the
duration of page fault processing. Hold i_mmap_rwsem longer in truncation
and hold punch code to cover the call to remove_inode_hugepages.
With this modification, code in remove_inode_hugepages checking for races
becomes 'dead' as it can not longer happen. Remove the dead code and
expand comments to explain reasoning. Similarly, checks for races with
truncation in the page fault path can be simplified and removed.

[merged] hugetlbfs-use-i_mmap_rwsem-for-more-pmd-sharing-synchronization.patch removed from -mm tree

Subject: hugetlbfs: use i_mmap_rwsem for more pmd sharing synchronization

------------------------------------------------------
From: Mike Kravetz <mike.kravetz(a)oracle.com>
Subject: hugetlbfs: use i_mmap_rwsem for more pmd sharing synchronization
While looking at BUGs associated with invalid huge page map counts, it was
discovered and observed that a huge pte pointer could become 'invalid' and
point to another task's page table. Consider the following:
A task takes a page fault on a shared hugetlbfs file and calls
huge_pte_alloc to get a ptep. Suppose the returned ptep points to a
shared pmd.
Now, another task truncates the hugetlbfs file. As part of truncation, it
unmaps everyone who has the file mapped. If the range being truncated is
covered by a shared pmd, huge_pmd_unshare will be called. For all but the
last user of the shared pmd, huge_pmd_unshare will clear the pud pointing
to the pmd. If the task in the middle of the page fault is not the last
user, the ptep returned by huge_pte_alloc now points to another task's
page table or worse. This leads to bad things such as incorrect page
map/reference counts or invalid memory references.
To fix, expand the use of i_mmap_rwsem as follows:
- i_mmap_rwsem is held in read mode whenever huge_pmd_share is called.
huge_pmd_share is only called via huge_pte_alloc, so callers of
huge_pte_alloc take i_mmap_rwsem before calling. In addition, callers
of huge_pte_alloc continue to hold the semaphore until finished with the
ptep.
- i_mmap_rwsem is held in write mode whenever huge_pmd_unshare is
called.

From: Michal Hocko <mhocko(a)suse.com>
Subject: hwpoison, memory_hotplug: allow hwpoisoned pages to be offlined
We have received a bug report that an injected MCE about faulty memory
prevents memory offline to succeed on 4.4 base kernel. The underlying
reason was that the HWPoison page has an elevated reference count and the
migration keeps failing. There are two problems with that. First of all
it is dubious to migrate the poisoned page because we know that accessing
that memory is possible to fail. Secondly it doesn't make any sense to
migrate a potentially broken content and preserve the memory corruption
over to a new location.
Oscar has found out that 4.4 and the current upstream kernels behave
slightly differently with his simply testcase
===
int main(void)
{
int ret;
int i;
int fd;
char *array = malloc(4096);
char *array_locked = malloc(4096);
fd = open("/tmp/data", O_RDONLY);
read(fd, array, 4095);
for (i = 0; i < 4096; i++)
array_locked[i] = 'd';
ret = mlock((void *)PAGE_ALIGN((unsigned long)array_locked), sizeof(array_locked));
if (ret)
perror("mlock");
sleep (20);
ret = madvise((void *)PAGE_ALIGN((unsigned long)array_locked), 4096, MADV_HWPOISON);
if (ret)
perror("madvise");
for (i = 0; i < 4096; i++)
array_locked[i] = 'd';
return 0;
}
===
+ offline this memory.
In 4.4 kernels he saw the hwpoisoned page to be returned back to the LRU

attempted to be migrated and that fails due to an elevated reference
count. It is quite possible that the reuse of the HWPoisoned page is some
kind of fixed race condition but I am not really sure about that.
With the upstream kernel the failure is slightly different. The page
doesn't seem to have LRU bit set but isolate_movable_page simply fails and
do_migrate_range simply puts all the isolated pages back to LRU and
therefore no progress is made and scan_movable_pages finds same set of
pages over and over again.
Fix both cases by explicitly checking HWPoisoned pages before we even try
to get reference on the page, try to unmap it if it is still mapped. As
explained by Naoya:
: Hwpoison code never unmapped those for no big reason because
: Ksm pages never dominate memory, so we simply didn't have strong
: motivation to save the pages.
Also put WARN_ON(PageLRU) in case there is a race and we can hit LRU
HWPoison pages which shouldn't happen but I couldn't convince myself about
that. Naoya has noted the following:
: Theoretically no such gurantee, because try_to_unmap() doesn't have a
: guarantee of success and then memory_failure() returns immediately
: when hwpoison_user_mappings fails.
: Or the following code (comes after hwpoison_user_mappings block) also impli=
: es
: that the target page can still have PageLRU flag.
:
: /*
: * Torn down by someone else?
: */
: if (PageLRU(p) && !PageSwapCache(p) && p->mapping =3D=3D NULL) {
: action_result(pfn, MF_MSG_TRUNCATED_LRU, MF_IGNORED);
: res =3D -EBUSY;
: goto out;
: }
:
: So I think it's OK to keep "if (WARN_ON(PageLRU(page)))" block in
: current version of your patch.

[merged] mm-hmm-mark-hmm_devmem_add-add_resource-export_symbol_gpl.patch removed from -mm tree

Subject: mm, hmm: mark hmm_devmem_{add, add_resource} EXPORT_SYMBOL_GPL
has been removed from the -mm tree. Its filename was
mm-hmm-mark-hmm_devmem_add-add_resource-export_symbol_gpl.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: Dan Williams <dan.j.williams(a)intel.com>
Subject: mm, hmm: mark hmm_devmem_{add, add_resource} EXPORT_SYMBOL_GPL
At Maintainer Summit, Greg brought up a topic I proposed around
EXPORT_SYMBOL_GPL usage. The motivation was considerations for when
EXPORT_SYMBOL_GPL is warranted and the criteria for taking the exceptional
step of reclassifying an existing export. Specifically, I wanted to make
the case that although the line is fuzzy and hard to specify in abstract
terms, it is nonetheless clear that devm_memremap_pages() and HMM
(Heterogeneous Memory Management) have crossed it. The
devm_memremap_pages() facility should have been EXPORT_SYMBOL_GPL from the
beginning, and HMM as a derivative of that functionality should have
naturally picked up that designation as well.
Contrary to typical rules, the HMM infrastructure was merged upstream with
zero in-tree consumers. There was a promise at the time that those users
would be merged "soon", but it has been over a year with no drivers
arriving. While the Nouveau driver is about to belatedly make good on
that promise it is clear that HMM was targeted first and foremost at an
out-of-tree consumer.
HMM is derived from devm_memremap_pages(), a facility Christoph and I
spearheaded to support persistent memory. It combines a device lifetime
model with a dynamically created 'struct page' / memmap array for any
physical address range. It enables coordination and control of the many
code paths in the kernel built to interact with memory via 'struct page'
objects. With HMM the integration goes even deeper by allowing device
drivers to hook and manipulate page fault and page free events.
One interpretation of when EXPORT_SYMBOL is suitable is when it is
exporting stable and generic leaf functionality. The
devm_memremap_pages() facility continues to see expanding use cases,
peer-to-peer DMA being the most recent, with no clear end date when it
will stop attracting reworks and semantic changes. It is not suitable to
export devm_memremap_pages() as a stable 3rd party driver API due to the
fact that it is still changing and manipulates core behavior. Moreover,
it is not in the best interest of the long term development of the core
memory management subsystem to permit any external driver to effectively
define its own system-wide memory management policies with no
encouragement to engage with upstream.
I am also concerned that HMM was designed in a way to minimize further
engagement with the core-MM. That, with these hooks in place,
device-drivers are free to implement their own policies without much
consideration for whether and how the core-MM could grow to meet that
need. Going forward not only should HMM be EXPORT_SYMBOL_GPL, but the
core-MM should be allowed the opportunity and stimulus to change and
address these new use cases as first class functionality.
Original changelog:
hmm_devmem_add(), and hmm_devmem_add_resource() duplicated
devm_memremap_pages() and are now simple now wrappers around the core
facility to inject a dev_pagemap instance into the global pgmap_radix and
hook page-idle events. The devm_memremap_pages() interface is base
infrastructure for HMM. HMM has more and deeper ties into the kernel
memory management implementation than base ZONE_DEVICE which is itself a
EXPORT_SYMBOL_GPL facility.
Originally, the HMM page structure creation routines copied the
devm_memremap_pages() code and reused ZONE_DEVICE. A cleanup to unify the
implementations was discussed during the initial review:
http://lkml.iu.edu/hypermail/linux/kernel/1701.2/00812.html Recent work to
extend devm_memremap_pages() for the peer-to-peer-DMA facility enabled
this cleanup to move forward.
In addition to the integration with devm_memremap_pages() HMM depends on
other GPL-only symbols:
mmu_notifier_unregister_no_release
percpu_ref
region_intersects
__class_create
It goes further to consume / indirectly expose functionality that is not
exported to any other driver:
alloc_pages_vma
walk_page_range
HMM is derived from devm_memremap_pages(), and extends deep core-kernel
fundamentals. Similar to devm_memremap_pages(), mark its entry points
EXPORT_SYMBOL_GPL().

------------------------------------------------------
From: Dan Williams <dan.j.williams(a)intel.com>
Subject: mm, hmm: replace hmm_devmem_pages_create() with devm_memremap_pages()
e8d513483300 "memremap: change devm_memremap_pages interface to use struct
dev_pagemap" refactored devm_memremap_pages() to allow a dev_pagemap
instance to be supplied. Passing in a dev_pagemap interface simplifies
the design of pgmap type drivers in that they can rely on container_of()
to lookup any private data associated with the given dev_pagemap instance.
In addition to the cleanups this also gives hmm users multi-order-radix
improvements that arrived with commit ab1b597ee0e4 "mm,
devm_memremap_pages: use multi-order radix for ZONE_DEVICE lookups"
As part of the conversion to the devm_memremap_pages() method of handling
the percpu_ref relative to when pages are put, the percpu_ref completion
needs to move to hmm_devmem_ref_exit(). See 71389703839e ("mm,
zone_device: Replace {get, put}_zone_device_page...") for details.

[merged] mm-hmm-use-devm-semantics-for-hmm_devmem_add-remove.patch removed from -mm tree
by akpm＠linux-foundation.org
The patch titled
Subject: mm, hmm: use devm semantics for hmm_devmem_{add, remove}
has been removed from the -mm tree. Its filename was
mm-hmm-use-devm-semantics-for-hmm_devmem_add-remove.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: Dan Williams <dan.j.williams(a)intel.com>
Subject: mm, hmm: use devm semantics for hmm_devmem_{add, remove}
devm semantics arrange for resources to be torn down when
device-driver-probe fails or when device-driver-release completes.
Similar to devm_memremap_pages() there is no need to support an explicit
remove operation when the users properly adhere to devm semantics.
Note that devm_kzalloc() automatically handles allocating node-local
memory.

[merged] mm-devm_memremap_pages-fix-shutdown-handling.patch removed from -mm tree
by akpm＠linux-foundation.org
The patch titled
Subject: mm, devm_memremap_pages: fix shutdown handling
has been removed from the -mm tree. Its filename was
mm-devm_memremap_pages-fix-shutdown-handling.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: Dan Williams <dan.j.williams(a)intel.com>
Subject: mm, devm_memremap_pages: fix shutdown handling
The last step before devm_memremap_pages() returns success is to allocate
a release action, devm_memremap_pages_release(), to tear the entire setup
down. However, the result from devm_add_action() is not checked.
Checking the error from devm_add_action() is not enough. The api
currently relies on the fact that the percpu_ref it is using is killed by
the time the devm_memremap_pages_release() is run. Rather than continue
this awkward situation, offload the responsibility of killing the
percpu_ref to devm_memremap_pages_release() directly. This allows
devm_memremap_pages() to do the right thing relative to init failures and
shutdown.
Without this change we could fail to register the teardown of
devm_memremap_pages(). The likelihood of hitting this failure is tiny as
small memory allocations almost always succeed. However, the impact of
the failure is large given any future reconfiguration, or disable/enable,
of an nvdimm namespace will fail forever as subsequent calls to
devm_memremap_pages() will fail to setup the pgmap_radix since there will
be stale entries for the physical address range.
An argument could be made to require that the ->kill() operation be set in
the @pgmap arg rather than passed in separately. However, it helps code
readability, tracking the lifetime of a given instance, to be able to grep
the kill routine directly at the devm_memremap_pages() call site.

has been removed from the -mm tree. Its filename was
mm-devm_memremap_pages-kill-mapping-system-ram-support.patch

------------------------------------------------------
From: Dan Williams <dan.j.williams(a)intel.com>
Subject: mm, devm_memremap_pages: kill mapping "System RAM" support
Given the fact that devm_memremap_pages() requires a percpu_ref that is
torn down by devm_memremap_pages_release() the current support for mapping
RAM is broken.
Support for remapping "System RAM" has been broken since the beginning and
there is no existing user of this this code path, so just kill the support
and make it an explicit error.
This cleanup also simplifies a follow-on patch to fix the error path when
setting a devm release action for devm_memremap_pages_release() fails.

has been removed from the -mm tree. Its filename was
mm-devm_memremap_pages-mark-devm_memremap_pages-export_symbol_gpl.patch

------------------------------------------------------
From: Dan Williams <dan.j.williams(a)intel.com>
Subject: mm, devm_memremap_pages: mark devm_memremap_pages() EXPORT_SYMBOL_GPL
devm_memremap_pages() is a facility that can create struct page entries
for any arbitrary range and give drivers the ability to subvert core
aspects of page management.
Specifically the facility is tightly integrated with the kernel's memory
hotplug functionality. It injects an altmap argument deep into the
architecture specific vmemmap implementation to allow allocating from
specific reserved pages, and it has Linux specific assumptions about page
structure reference counting relative to get_user_pages() and
get_user_pages_fast(). It was an oversight and a mistake that this was
not marked EXPORT_SYMBOL_GPL from the outset.
Again, devm_memremap_pagex() exposes and relies upon core kernel internal
assumptions and will continue to evolve along with 'struct page', memory
hotplug, and support for new memory types / topologies. Only an in-kernel
GPL-only driver is expected to keep up with this ongoing evolution. This
interface, and functionality derived from this interface, is not suitable
for kernel-external drivers.

[PATCH v3 1/2] hugetlbfs: use i_mmap_rwsem for more pmd sharing synchronization
by Mike Kravetz
While looking at BUGs associated with invalid huge page map counts,
it was discovered and observed that a huge pte pointer could become
'invalid' and point to another task's page table. Consider the
following:
A task takes a page fault on a shared hugetlbfs file and calls
huge_pte_alloc to get a ptep. Suppose the returned ptep points to a
shared pmd.
Now, another task truncates the hugetlbfs file. As part of truncation,
it unmaps everyone who has the file mapped. If the range being
truncated is covered by a shared pmd, huge_pmd_unshare will be called.
For all but the last user of the shared pmd, huge_pmd_unshare will
clear the pud pointing to the pmd. If the task in the middle of the
page fault is not the last user, the ptep returned by huge_pte_alloc
now points to another task's page table or worse. This leads to bad
things such as incorrect page map/reference counts or invalid memory
references.
To fix, expand the use of i_mmap_rwsem as follows:
- i_mmap_rwsem is held in read mode whenever huge_pmd_share is called.
huge_pmd_share is only called via huge_pte_alloc, so callers of
huge_pte_alloc take i_mmap_rwsem before calling. In addition, callers
of huge_pte_alloc continue to hold the semaphore until finished with
the ptep.
- i_mmap_rwsem is held in write mode whenever huge_pmd_unshare is called.

[PATCH 1/3] ext4: avoid kernel warning when writing the superblock to a dead device
by Theodore Ts'o
The xfstests generic/475 test switches the underlying device with
dm-error while running a stress test. This results in a large number
of file system errors, and since we can't lock the buffer head when
marking the superblock dirty in the ext4_grp_locked_error() case, it's
possible the superblock to be !buffer_uptodate() without
buffer_write_io_error() being true.
We need to set buffer_uptodate() before we call mark_buffer_dirty() or
this will trigger a WARN_ON. It's safe to do this since the
superblock must have been properly read into memory or the mount would
have been successful. So if buffer_uptodate() is not set, we can
safely assume that this happened due to a failed attempt to write the
superblock.

[PATCH] ibmveth: fix DMA unmap error in ibmveth_xmit_start error path
by Tyrel Datwyler
Commit 33a48ab105a7 ("ibmveth: Fix DMA unmap error") fixed an issue in the
normal code path of ibmveth_xmit_start() that was originally introduced by
Commit 6e8ab30ec677 ("ibmveth: Add scatter-gather support"). This original
fix missed the error path where dma_unmap_page is wrongly called on the
header portion in descs[0] which was mapped with dma_map_single. As a
result a failure to DMA map any of the frags results in a dmesg warning
when CONFIG_DMA_API_DEBUG is enabled.

[PATCH 1/2] MIPS: Fix a R10000_LLSC_WAR logic in atomic.h
by Huacai Chen
Commit 4936084c2ee227524c242d79 ("MIPS: Cleanup R10000_LLSC_WAR logic
in atomic.h") introduce a mistake in atomic64_fetch_##op##_relaxed(),
because it forget to delete R10000_LLSC_WAR in the if-condition. So fix
it.

4.14 backport request for dbdda842fe96f: "printk: Add console owner and waiter logic to load balance console writes"
by Daniel Wang
Prior to this change, the combination of `softlockup_panic=1` and
`softlockup_all_cpu_stacktrace=1` may result in a deadlock when the reboot path
is trying to grab the console lock that is held by the stack trace printing
path. What seems to be happening is that while there are multiple CPUs, only one
of them is tasked to print the back trace of all CPUs. On a machine with many
CPUs and a slow serial console (on Google Compute Engine for example), the stack
trace printing routine hits a timeout and the reboot path kicks in. The latter
then tries to print something else, but can't get the lock because it's still
held by earlier printing path. This is easily reproducible on a VM with 16+
vCPUs on Google Compute Engine - which is a very common scenario.
A quick repro is available at
https://github.com/wonderfly/printk-deadlock-repro. The system hangs 3 seconds
into executing repro.sh. Both deadlock analysis and repro are credits to Peter
Feiner.
Note that I have read previous discussions on backporting this to stable [1].
The argument for objecting the backport was that this is a non-trivial fix and
is supported to prevent hypothetical soft lockups. What we are hitting is a real
deadlock, in production, however. Hence this request.
[1] https://lore.kernel.org/lkml/20180409081535.dq7p5bfnpvd3xk3t@pathway.suse.c…
Serial console logs leading up to the deadlock. As can be seen the stack trace
was incomplete because the printing path hit a timeout.

[PATCH AUTOSEL 4.14 01/35] media: omap3isp: Unregister media device as first
by Sasha Levin
From: Sakari Ailus <sakari.ailus(a)linux.intel.com>
[ Upstream commit 30efae3d789cd0714ef795545a46749236e29558 ]
While there are issues related to object lifetime management, unregister the
media device first when the driver is being unbound. This is slightly
safer.

From: NeilBrown <neil(a)brown.name>
Subject: lib/gen_crc64table.c: don't depend on linux headers being installed
gen_crc64table requires linux include files to be installed in
/usr/include/linux. This is a new requrement so hosts that could
previously build the kernel, now cannot.
gen_crc64table makes this requirement by including <linux/swab.h>, but
nothing from that header is actually used.
So remove the #include, so that the linux headers no longer need to be
installed.

[PATCH] Fix failure path in alloc_pid()
by Matthew Wilcox
The failure path removes the allocated PIDs from the wrong namespace.
This could lead to us inadvertently reusing PIDs in the leaf namespace
and leaking PIDs in parent namespaces.
Fixes: 95846ecf9dac ("pid: replace pid bitmap implementation with IDR API")

stable request: mm, page_alloc: actually ignore mempolicies for high priority allocations
by Mike Manning
Hello, Please consider backporting to 4.14.y the following commit from
kernel-net-next by Vlastimil Babka [CC'ed]:
d6a24df00638 ("mm, page_alloc: actually ignore mempolicies for high
priority allocations") It cherry-picks cleanly and builds fine.
The reason for the request is that the commit 1d26c112959f
<http://stash.eng.vyatta.net:7990/projects/VC/repos/linux-vyatta/commits/1d2…> ("mm,
page_alloc:do not break __GFP_THISNODE by zonelist reset") that was
previously backported to 4.14.y broke some of our functionality after we
upgraded from an earlier 4.14 kernel without the fix. The reason this is
happening is not clear, with this commit only found by bisect.
Fortunately the requested commit resolves the issue.
Best Regards,
Mike Manning

Subject: [PATCH] mm: thp: fix flags for pmd migration when split
When splitting a huge migrating PMD, we'll transfer all the existing PMD
bits and apply them again onto the small PTEs. However we are fetching
the bits unconditionally via pmd_soft_dirty(), pmd_write() or
pmd_yound() while actually they don't make sense at all when it's a
migration entry. Fix them up. Since at it, drop the ifdef together as
not needed.
Note that if my understanding is correct about the problem then if
without the patch there is chance to lose some of the dirty bits in the
migrating pmd pages (on x86_64 we're fetching bit 11 which is part of
swap offset instead of bit 2) and it could potentially corrupt the
memory of an userspace program which depends on the dirty bit.

[patch 166/167] memcg, oom: notify on oom killer invocation from the charge path
by akpm＠linux-foundation.org
From: Michal Hocko <mhocko(a)suse.com>
Subject: memcg, oom: notify on oom killer invocation from the charge path
Burt Holzman has noticed that memcg v1 doesn't notify about OOM events via
eventfd anymore. The reason is that 29ef680ae7c2 ("memcg, oom: move
out_of_memory back to the charge path") has moved the oom handling back to
the charge path. While doing so the notification was left behind in
mem_cgroup_oom_synchronize.
Fix the issue by replicating the oom hierarchy locking and the
notification.

[patch 165/167] mm, swap: fix swapoff with KSM pages
by akpm＠linux-foundation.org
From: Huang Ying <ying.huang(a)intel.com>
Subject: mm, swap: fix swapoff with KSM pages
KSM pages may be mapped to the multiple VMAs that cannot be reached from
one anon_vma. So during swapin, a new copy of the page need to be
generated if a different anon_vma is needed, please refer to comments of
ksm_might_need_to_copy() for details.
During swapoff, unuse_vma() uses anon_vma (if available) to locate VMA and
virtual address mapped to the page, so not all mappings to a swapped out
KSM page could be found. So in try_to_unuse(), even if the swap count of
a swap entry isn't zero, the page needs to be deleted from swap cache, so
that, in the next round a new page could be allocated and swapin for the
other mappings of the swapped out KSM page.
But this contradicts with the THP swap support. Where the THP could be
deleted from swap cache only after the swap count of every swap entry in
the huge swap cluster backing the THP has reach 0. So try_to_unuse() is
changed in commit e07098294adf ("mm, THP, swap: support to reclaim swap
space for THP swapped out") to check that before delete a page from swap
cache, but this has broken KSM swapoff too.
Fortunately, KSM is for the normal pages only, so the original behavior
for KSM pages could be restored easily via checking PageTransCompound().
That is how this patch works.
The bug is introduced by e07098294adf ("mm, THP, swap: support to reclaim
swap space for THP swapped out"), which is merged by v4.14-rc1. So I
think we should backport the fix to from 4.14 on. But Hugh thinks it may
be rare for the KSM pages being in the swap device when swapoff, so nobody
reports the bug so far.

[patch 162/167] hugetlbfs: Use i_mmap_rwsem to fix page fault/truncate race
by akpm＠linux-foundation.org
From: Mike Kravetz <mike.kravetz(a)oracle.com>
Subject: hugetlbfs: Use i_mmap_rwsem to fix page fault/truncate race
hugetlbfs page faults can race with truncate and hole punch operations.
Current code in the page fault path attempts to handle this by 'backing
out' operations if we encounter the race. One obvious omission in the
current code is removing a page newly added to the page cache. This is
pretty straight forward to address, but there is a more subtle and
difficult issue of backing out hugetlb reservations. To handle this
correctly, the 'reservation state' before page allocation needs to be
noted so that it can be properly backed out. There are four distinct
possibilities for reservation state: shared/reserved, shared/no-resv,
private/reserved and private/no-resv. Backing out a reservation may
require memory allocation which could fail so that needs to be taken into
account as well.
Instead of writing the required complicated code for this rare occurrence,
just eliminate the race. i_mmap_rwsem is now held in read mode for the
duration of page fault processing. Hold i_mmap_rwsem longer in truncation
and hold punch code to cover the call to remove_inode_hugepages.
With this modification, code in remove_inode_hugepages checking for races
becomes 'dead' as it can not longer happen. Remove the dead code and
expand comments to explain reasoning. Similarly, checks for races with
truncation in the page fault path can be simplified and removed.

[patch 161/167] hugetlbfs: use i_mmap_rwsem for more pmd sharing synchronization
by akpm＠linux-foundation.org
From: Mike Kravetz <mike.kravetz(a)oracle.com>
Subject: hugetlbfs: use i_mmap_rwsem for more pmd sharing synchronization
While looking at BUGs associated with invalid huge page map counts, it was
discovered and observed that a huge pte pointer could become 'invalid' and
point to another task's page table. Consider the following:
A task takes a page fault on a shared hugetlbfs file and calls
huge_pte_alloc to get a ptep. Suppose the returned ptep points to a
shared pmd.
Now, another task truncates the hugetlbfs file. As part of truncation, it
unmaps everyone who has the file mapped. If the range being truncated is
covered by a shared pmd, huge_pmd_unshare will be called. For all but the
last user of the shared pmd, huge_pmd_unshare will clear the pud pointing
to the pmd. If the task in the middle of the page fault is not the last
user, the ptep returned by huge_pte_alloc now points to another task's
page table or worse. This leads to bad things such as incorrect page
map/reference counts or invalid memory references.
To fix, expand the use of i_mmap_rwsem as follows:
- i_mmap_rwsem is held in read mode whenever huge_pmd_share is called.
huge_pmd_share is only called via huge_pte_alloc, so callers of
huge_pte_alloc take i_mmap_rwsem before calling. In addition, callers
of huge_pte_alloc continue to hold the semaphore until finished with the
ptep.
- i_mmap_rwsem is held in write mode whenever huge_pmd_unshare is
called.

[patch 135/167] hwpoison, memory_hotplug: allow hwpoisoned pages to be offlined
by akpm＠linux-foundation.org
From: Michal Hocko <mhocko(a)suse.com>
Subject: hwpoison, memory_hotplug: allow hwpoisoned pages to be offlined
We have received a bug report that an injected MCE about faulty memory
prevents memory offline to succeed on 4.4 base kernel. The underlying
reason was that the HWPoison page has an elevated reference count and the
migration keeps failing. There are two problems with that. First of all
it is dubious to migrate the poisoned page because we know that accessing
that memory is possible to fail. Secondly it doesn't make any sense to
migrate a potentially broken content and preserve the memory corruption
over to a new location.
Oscar has found out that 4.4 and the current upstream kernels behave
slightly differently with his simply testcase
===
int main(void)
{
int ret;
int i;
int fd;
char *array = malloc(4096);
char *array_locked = malloc(4096);
fd = open("/tmp/data", O_RDONLY);
read(fd, array, 4095);
for (i = 0; i < 4096; i++)
array_locked[i] = 'd';
ret = mlock((void *)PAGE_ALIGN((unsigned long)array_locked), sizeof(array_locked));
if (ret)
perror("mlock");
sleep (20);
ret = madvise((void *)PAGE_ALIGN((unsigned long)array_locked), 4096, MADV_HWPOISON);
if (ret)
perror("madvise");
for (i = 0; i < 4096; i++)
array_locked[i] = 'd';
return 0;
}
===
+ offline this memory.
In 4.4 kernels he saw the hwpoisoned page to be returned back to the LRU
list
kernel: [<ffffffff81019ac9>] dump_trace+0x59/0x340

And that latter confuses the hotremove path because an LRU page is
attempted to be migrated and that fails due to an elevated reference
count. It is quite possible that the reuse of the HWPoisoned page is some
kind of fixed race condition but I am not really sure about that.
With the upstream kernel the failure is slightly different. The page
doesn't seem to have LRU bit set but isolate_movable_page simply fails and
do_migrate_range simply puts all the isolated pages back to LRU and
therefore no progress is made and scan_movable_pages finds same set of
pages over and over again.
Fix both cases by explicitly checking HWPoisoned pages before we even try
to get reference on the page, try to unmap it if it is still mapped. As
explained by Naoya:
: Hwpoison code never unmapped those for no big reason because
: Ksm pages never dominate memory, so we simply didn't have strong
: motivation to save the pages.
Also put WARN_ON(PageLRU) in case there is a race and we can hit LRU
HWPoison pages which shouldn't happen but I couldn't convince myself about
that. Naoya has noted the following:
: Theoretically no such gurantee, because try_to_unmap() doesn't have a
: guarantee of success and then memory_failure() returns immediately
: when hwpoison_user_mappings fails.
: Or the following code (comes after hwpoison_user_mappings block) also impli=
: es
: that the target page can still have PageLRU flag.
:
: /*
: * Torn down by someone else?
: */
: if (PageLRU(p) && !PageSwapCache(p) && p->mapping =3D=3D NULL) {
: action_result(pfn, MF_MSG_TRUNCATED_LRU, MF_IGNORED);
: res =3D -EBUSY;
: goto out;
: }
:
: So I think it's OK to keep "if (WARN_ON(PageLRU(page)))" block in
: current version of your patch.

[patch 090/167] mm, hmm: mark hmm_devmem_{add, add_resource} EXPORT_SYMBOL_GPL
by akpm＠linux-foundation.org
From: Dan Williams <dan.j.williams(a)intel.com>
Subject: mm, hmm: mark hmm_devmem_{add, add_resource} EXPORT_SYMBOL_GPL
At Maintainer Summit, Greg brought up a topic I proposed around
EXPORT_SYMBOL_GPL usage. The motivation was considerations for when
EXPORT_SYMBOL_GPL is warranted and the criteria for taking the exceptional
step of reclassifying an existing export. Specifically, I wanted to make
the case that although the line is fuzzy and hard to specify in abstract
terms, it is nonetheless clear that devm_memremap_pages() and HMM
(Heterogeneous Memory Management) have crossed it. The
devm_memremap_pages() facility should have been EXPORT_SYMBOL_GPL from the
beginning, and HMM as a derivative of that functionality should have
naturally picked up that designation as well.
Contrary to typical rules, the HMM infrastructure was merged upstream with
zero in-tree consumers. There was a promise at the time that those users
would be merged "soon", but it has been over a year with no drivers
arriving. While the Nouveau driver is about to belatedly make good on
that promise it is clear that HMM was targeted first and foremost at an
out-of-tree consumer.
HMM is derived from devm_memremap_pages(), a facility Christoph and I
spearheaded to support persistent memory. It combines a device lifetime
model with a dynamically created 'struct page' / memmap array for any
physical address range. It enables coordination and control of the many
code paths in the kernel built to interact with memory via 'struct page'
objects. With HMM the integration goes even deeper by allowing device
drivers to hook and manipulate page fault and page free events.
One interpretation of when EXPORT_SYMBOL is suitable is when it is
exporting stable and generic leaf functionality. The
devm_memremap_pages() facility continues to see expanding use cases,
peer-to-peer DMA being the most recent, with no clear end date when it
will stop attracting reworks and semantic changes. It is not suitable to
export devm_memremap_pages() as a stable 3rd party driver API due to the
fact that it is still changing and manipulates core behavior. Moreover,
it is not in the best interest of the long term development of the core
memory management subsystem to permit any external driver to effectively
define its own system-wide memory management policies with no
encouragement to engage with upstream.
I am also concerned that HMM was designed in a way to minimize further
engagement with the core-MM. That, with these hooks in place,
device-drivers are free to implement their own policies without much
consideration for whether and how the core-MM could grow to meet that
need. Going forward not only should HMM be EXPORT_SYMBOL_GPL, but the
core-MM should be allowed the opportunity and stimulus to change and
address these new use cases as first class functionality.
Original changelog:
hmm_devmem_add(), and hmm_devmem_add_resource() duplicated
devm_memremap_pages() and are now simple now wrappers around the core
facility to inject a dev_pagemap instance into the global pgmap_radix and
hook page-idle events. The devm_memremap_pages() interface is base
infrastructure for HMM. HMM has more and deeper ties into the kernel
memory management implementation than base ZONE_DEVICE which is itself a
EXPORT_SYMBOL_GPL facility.
Originally, the HMM page structure creation routines copied the
devm_memremap_pages() code and reused ZONE_DEVICE. A cleanup to unify the
implementations was discussed during the initial review:
http://lkml.iu.edu/hypermail/linux/kernel/1701.2/00812.html Recent work to
extend devm_memremap_pages() for the peer-to-peer-DMA facility enabled
this cleanup to move forward.
In addition to the integration with devm_memremap_pages() HMM depends on
other GPL-only symbols:
mmu_notifier_unregister_no_release
percpu_ref
region_intersects
__class_create
It goes further to consume / indirectly expose functionality that is not
exported to any other driver:
alloc_pages_vma
walk_page_range
HMM is derived from devm_memremap_pages(), and extends deep core-kernel
fundamentals. Similar to devm_memremap_pages(), mark its entry points
EXPORT_SYMBOL_GPL().

[patch 089/167] mm, hmm: replace hmm_devmem_pages_create() with devm_memremap_pages()
by akpm＠linux-foundation.org
From: Dan Williams <dan.j.williams(a)intel.com>
Subject: mm, hmm: replace hmm_devmem_pages_create() with devm_memremap_pages()
e8d513483300 "memremap: change devm_memremap_pages interface to use struct
dev_pagemap" refactored devm_memremap_pages() to allow a dev_pagemap
instance to be supplied. Passing in a dev_pagemap interface simplifies
the design of pgmap type drivers in that they can rely on container_of()
to lookup any private data associated with the given dev_pagemap instance.
In addition to the cleanups this also gives hmm users multi-order-radix
improvements that arrived with commit ab1b597ee0e4 "mm,
devm_memremap_pages: use multi-order radix for ZONE_DEVICE lookups"
As part of the conversion to the devm_memremap_pages() method of handling
the percpu_ref relative to when pages are put, the percpu_ref completion
needs to move to hmm_devmem_ref_exit(). See 71389703839e ("mm,
zone_device: Replace {get, put}_zone_device_page...") for details.

[patch 088/167] mm, hmm: use devm semantics for hmm_devmem_{add, remove}
by akpm＠linux-foundation.org
From: Dan Williams <dan.j.williams(a)intel.com>
Subject: mm, hmm: use devm semantics for hmm_devmem_{add, remove}
devm semantics arrange for resources to be torn down when
device-driver-probe fails or when device-driver-release completes.
Similar to devm_memremap_pages() there is no need to support an explicit
remove operation when the users properly adhere to devm semantics.
Note that devm_kzalloc() automatically handles allocating node-local
memory.

[patch 086/167] mm, devm_memremap_pages: fix shutdown handling
by akpm＠linux-foundation.org
From: Dan Williams <dan.j.williams(a)intel.com>
Subject: mm, devm_memremap_pages: fix shutdown handling
The last step before devm_memremap_pages() returns success is to allocate
a release action, devm_memremap_pages_release(), to tear the entire setup
down. However, the result from devm_add_action() is not checked.
Checking the error from devm_add_action() is not enough. The api
currently relies on the fact that the percpu_ref it is using is killed by
the time the devm_memremap_pages_release() is run. Rather than continue
this awkward situation, offload the responsibility of killing the
percpu_ref to devm_memremap_pages_release() directly. This allows
devm_memremap_pages() to do the right thing relative to init failures and
shutdown.
Without this change we could fail to register the teardown of
devm_memremap_pages(). The likelihood of hitting this failure is tiny as
small memory allocations almost always succeed. However, the impact of
the failure is large given any future reconfiguration, or disable/enable,
of an nvdimm namespace will fail forever as subsequent calls to
devm_memremap_pages() will fail to setup the pgmap_radix since there will
be stale entries for the physical address range.
An argument could be made to require that the ->kill() operation be set in
the @pgmap arg rather than passed in separately. However, it helps code
readability, tracking the lifetime of a given instance, to be able to grep
the kill routine directly at the devm_memremap_pages() call site.

[patch 085/167] mm, devm_memremap_pages: kill mapping "System RAM" support
by akpm＠linux-foundation.org
From: Dan Williams <dan.j.williams(a)intel.com>
Subject: mm, devm_memremap_pages: kill mapping "System RAM" support
Given the fact that devm_memremap_pages() requires a percpu_ref that is
torn down by devm_memremap_pages_release() the current support for mapping
RAM is broken.
Support for remapping "System RAM" has been broken since the beginning and
there is no existing user of this this code path, so just kill the support
and make it an explicit error.
This cleanup also simplifies a follow-on patch to fix the error path when
setting a devm release action for devm_memremap_pages_release() fails.

[patch 084/167] mm, devm_memremap_pages: mark devm_memremap_pages() EXPORT_SYMBOL_GPL
by akpm＠linux-foundation.org
From: Dan Williams <dan.j.williams(a)intel.com>
Subject: mm, devm_memremap_pages: mark devm_memremap_pages() EXPORT_SYMBOL_GPL
devm_memremap_pages() is a facility that can create struct page entries
for any arbitrary range and give drivers the ability to subvert core
aspects of page management.
Specifically the facility is tightly integrated with the kernel's memory
hotplug functionality. It injects an altmap argument deep into the
architecture specific vmemmap implementation to allow allocating from
specific reserved pages, and it has Linux specific assumptions about page
structure reference counting relative to get_user_pages() and
get_user_pages_fast(). It was an oversight and a mistake that this was
not marked EXPORT_SYMBOL_GPL from the outset.
Again, devm_memremap_pagex() exposes and relies upon core kernel internal
assumptions and will continue to evolve along with 'struct page', memory
hotplug, and support for new memory types / topologies. Only an in-kernel
GPL-only driver is expected to keep up with this ongoing evolution. This
interface, and functionality derived from this interface, is not suitable
for kernel-external drivers.

From: Michal Hocko <mhocko(a)suse.com>
Subject: memcg, oom: notify on oom killer invocation from the charge path
Burt Holzman has noticed that memcg v1 doesn't notify about OOM events via
eventfd anymore. The reason is that 29ef680ae7c2 ("memcg, oom: move
out_of_memory back to the charge path") has moved the oom handling back to
the charge path. While doing so the notification was left behind in
mem_cgroup_oom_synchronize.
Fix the issue by replicating the oom hierarchy locking and the
notification.

[PATCH stable] ubifs: Handle re-linking of inodes correctly while recovery
by Rafał Miłecki
From: Richard Weinberger <richard(a)nod.at>
commit e58725d51fa8da9133f3f1c54170aa2e43056b91 upstream.
UBIFS's recovery code strictly assumes that a deleted inode will never
come back, therefore it removes all data which belongs to that inode
as soon it faces an inode with link count 0 in the replay list.
Before O_TMPFILE this assumption was perfectly fine. With O_TMPFILE
it can lead to data loss upon a power-cut.
Consider a journal with entries like:
0: inode X (nlink = 0) /* O_TMPFILE was created */
1: data for inode X /* Someone writes to the temp file */
2: inode X (nlink = 0) /* inode was changed, xattr, chmod, … */
3: inode X (nlink = 1) /* inode was re-linked via linkat() */
Upon replay of entry #2 UBIFS will drop all data that belongs to inode X,
this will lead to an empty file after mounting.
As solution for this problem, scan the replay list for a re-link entry
before dropping data.

suggest 00b80ac93553 ("spi: imx: mx51-ecspi: Move some initialisation to prepare_message hook.") for stable backports
by Uwe Kleine-König
Hello,
even though the subject sounds harmless it fixes a real bug.
(Yes, I'm aware that commit isn't in Linus' tree yet, but I assume your
tracking of patches targetting stable is better than mine, so I didn't
wait :-)
For backporting you also need its parent commit (i.e. e697271c4e29
("spi: imx: add a device specific prepare_message callback")). I have a
local backport to v4.14 here which isn't entirely trivial. So just tell
me if you need help.
Best regards
Uwe

The reason is we do not pass the Head to page_hstate(), and so, the call
to compound_order() in page_hstate() returns 0, so we end up checking all
hstates's size to match PAGE_SIZE.
Obviously, we do not find any hstate matching that size, and we return
NULL. Then, we dereference that NULL pointer in
hugepage_migration_supported() and we got the #PF from above.
Fix that by getting the head page before calling page_hstate().
Also, since gigantic pages span several pageblocks, re-adjust the logic
for skipping pages. While are it, we can also get rid of the round_up().

This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: Rik van Riel <riel(a)surriel.com>
Subject: fork,memcg: fix crash in free_thread_stack on memcg charge fail
Changeset 9b6f7e163cd0 ("mm: rework memcg kernel stack accounting")
will result in fork failing if allocating a kernel stack for a task
in dup_task_struct exceeds the kernel memory allowance for that cgroup.
Unfortunately, it also results in a crash.
This is due to the code jumping to free_stack and calling free_thread_stack
when the memcg kernel stack charge fails, but without tsk->stack pointing
at the freshly allocated stack.
This in turn results in the vfree_atomic in free_thread_stack oopsing
with a backtrace like this:
#5 [ffffc900244efc88] die at ffffffff8101f0ab
#6 [ffffc900244efcb8] do_general_protection at ffffffff8101cb86

by akpm＠linux-foundation.org
The patch titled
Subject: mm: thp: fix flags for pmd migration when split
has been removed from the -mm tree. Its filename was
mm-thp-fix-flags-for-pmd-migration-when-split.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: Peter Xu <peterx(a)redhat.com>
Subject: mm: thp: fix flags for pmd migration when split
When splitting a huge migrating PMD, we'll transfer all the existing PMD
bits and apply them again onto the small PTEs. However we are fetching
the bits unconditionally via pmd_soft_dirty(), pmd_write() or pmd_yound()
while actually they don't make sense at all when it's a migration entry.
Fix them up. Since at it, drop the ifdef together as not needed.
Note that if my understanding is correct about the problem then if without
the patch there is chance to lose some of the dirty bits in the migrating
pmd pages (on x86_64 we're fetching bit 11 which is part of swap offset
instead of bit 2) and it could potentially corrupt the memory of an
userspace program which depends on the dirty bit.

The patch titled

Subject: mm, memory_hotplug: initialize struct pages for the full memory section
If memory end is not aligned with the sparse memory section boundary, the
mapping of such a section is only partly initialized. This may lead to
VM_BUG_ON due to uninitialized struct page access from
is_mem_section_removable() or test_pages_in_a_zone() function triggered by
memory_hotplug sysfs handlers:
Here are the the panic examples:

Fix the problem by initializing the last memory section of each zone in
memmap_init_zone() till the very end, even if it goes beyond the zone end.
Michal said:

[PATCH AUTOSEL 3.18 01/12] powerpc: Fix COFF zImage booting on old powermacs
by Sasha Levin
From: Paul Mackerras <paulus(a)ozlabs.org>
[ Upstream commit 5564597d51c8ff5b88d95c76255e18b13b760879 ]
Commit 6975a783d7b4 ("powerpc/boot: Allow building the zImage wrapper
as a relocatable ET_DYN", 2011-04-12) changed the procedure descriptor
at the start of crt0.S to have a hard-coded start address of 0x500000
rather than a reference to _zimage_start, presumably because having
a reference to a symbol introduced a relocation which is awkward to
handle in a position-independent executable. Unfortunately, what is
at 0x500000 in the COFF image is not the first instruction, but the
procedure descriptor itself, that is, a word containing 0x500000,
which is not a valid instruction. Hence, booting a COFF zImage
results in a "DEFAULT CATCH!, code=FFF00700" message from Open
Firmware.
This fixes the problem by (a) putting the procedure descriptor in the
data section and (b) adding a branch to _zimage_start as the first
instruction in the program.

[PATCH AUTOSEL 4.9 01/35] pinctrl: meson: fix pull enable register calculation
by Sasha Levin
From: Jerome Brunet <jbrunet(a)baylibre.com>
[ Upstream commit 614b1868a125a0ba24be08f3a7fa832ddcde6bca ]
We just changed the code so we apply bias disable on the correct
register but forgot to align the register calculation. The result
is that we apply the change on the correct register, but possibly
at the incorrect offset/bit
This went undetected because offsets tends to be the same between
REG_PULL and REG_PULLEN for a given pin the EE controller. This
is not true for the AO controller.

[PATCH AUTOSEL 4.19 01/97] ARM: dts: sun8i: a83t: bananapi-m3: increase vcc-pd voltage to 3.3V
by Sasha Levin
From: Corentin Labbe <clabbe(a)baylibre.com>
[ Upstream commit 5f8208f557065163f9a8089ea2ea7888f9d96922 ]
Since commit d7c5f6863550 ("ARM: dts: sun8i: a83t: bananapi-m3: Add
AXP813 regulator nodes") my BPIM3 no longer works at gigabit speed.
With the default setting, dldo3 is regulated at 2.9v which seems
sufficient for the PHY but the aforementioned commit drops it to 2.5V
which is insufficient. Note that this behaviour is random for all BPIM3.
Some work with 2.5V, but some don't.
Finnaly, someone from Bananapi confirmed that this regulator must be set
to 3.3V.
Fixes: d7c5f6863550 ("ARM: dts: sun8i: a83t: bananapi-m3: Add AXP813
regulator nodes")

QT 5.12 and statx - maybe backport it to older LTS kernels
by Philip Müller
Hi Greg,
seems with following commit [1] in QT 5.12 there might be a need to have
also statx [2] backported to older LTS kernels. What do you think?
Best, Philip

[PATCH 1/1] bcache: treat stale && dirty keys as bad keys
by Coly Li
From: Tang Junhui <tang.junhui.linux(a)gmail.com>
Stale && dirty keys can be produced in the follow way:
After writeback in write_dirty_finish(), dirty keys k1 will
replace by clean keys k2
==>ret = bch_btree_insert(dc->disk.c, &keys, NULL, &w->key);
==>btree_insert_fn(struct btree_op *b_op, struct btree *b)
==>static int bch_btree_insert_node(struct btree *b,
struct btree_op *op,
struct keylist *insert_keys,
atomic_t *journal_ref,
Then two steps:
A) update k1 to k2 in btree node memory;
bch_btree_insert_keys(b, op, insert_keys, replace_key)
B) Write the bset(contains k2) to cache disk by a 30s delay work
bch_btree_leaf_dirty(b, journal_ref).
But before the 30s delay work write the bset to cache device,
these things happened:
A) GC works, and reclaim the bucket k2 point to;
B) Allocator works, and invalidate the bucket k2 point to,
and increase the gen of the bucket, and place it into free_inc
fifo;
C) Until now, the 30s delay work still does not finish work,
so in the disk, the key still is k1, it is dirty and stale
(its gen is smaller than the gen of the bucket). and then the
machine power off suddenly happens;
D) When the machine power on again, after the btree reconstruction,
the stale dirty key appear.
In bch_extent_bad(), when expensive_debug_checks is off, it would
treat the dirty key as good even it is stale keys, and it would
cause bellow probelms:
A) In read_dirty() it would cause machine crash:
BUG_ON(ptr_stale(dc->disk.c, &w->key, 0));
B) It could be worse when reads hits stale dirty keys, it would
read old incorrect data.
This patch tolerate the existence of these stale && dirty keys,
and treat them as bad key in bch_extent_bad().

client)

[PATCH] ubifs: Get/put page when changing PG_private
by Richard Weinberger
The page migration code assumes that a page with PG_private
set has its page count elevated by 1.
UBIFS never did this and therefore the migration code was unable
to migrate some pages owned by UBIFS.
The lead to situations where the CMA memory allocator failed to
allocate memory.
Fix this by using get/put_page when changing PG_private.

The 4.18 stable branch is no longer maintained.
I suspect this is the same as <https://bugs.debian.org/914495> and
<https://bugs.freedesktop.org/show_bug.cgi?id=108850>, which is fixed
in 4.19 (currently in unstable).

[PATCH] Revert "serial: 8250: Fix clearing FIFOs in RS485 mode again"
by Paul Burton
Commit f6aa5beb45be ("serial: 8250: Fix clearing FIFOs in RS485 mode
again") makes a change to FIFO clearing code which its commit message
suggests was intended to be specific to use with RS485 mode, however:
1) The change made does not just affect __do_stop_tx_rs485(), it also
affects other uses of serial8250_clear_fifos() including paths for
starting up, shutting down or auto-configuring a port regardless of
whether it's an RS485 port or not.
2) It makes the assumption that resetting the FIFOs is a no-op when
FIFOs are disabled, and as such it checks for this case & explicitly
avoids setting the FIFO reset bits when the FIFO enable bit is
clear. A reading of the PC16550D manual would suggest that this is
OK since the FIFO should automatically be reset if it is later
enabled, but we support many 16550-compatible devices and have never
required this auto-reset behaviour for at least the whole git era.
Starting to rely on it now seems risky, offers no benefit, and
indeed breaks at least the Ingenic JZ4780's UARTs which reads
garbage when the RX FIFO is enabled if we don't explicitly reset it.
3) By only resetting the FIFOs if they're enabled, the behaviour of
serial8250_do_startup() during boot now depends on what the value of
FCR is before the 8250 driver is probed. This in itself seems
questionable and leaves us with FCR=0 & no FIFO reset if the UART
was used by 8250_early, otherwise it depends upon what the
bootloader left behind.
4) Although the naming of serial8250_clear_fifos() may be unclear, it
is clear that callers of it expect that it will disable FIFOs. Both
serial8250_do_startup() & serial8250_do_shutdown() contain comments
to that effect, and other callers explicitly re-enable the FIFOs
after calling serial8250_clear_fifos(). The premise of that patch
that disabling the FIFOs is incorrect therefore seems wrong.
For these reasons, this reverts commit f6aa5beb45be ("serial: 8250: Fix
clearing FIFOs in RS485 mode again").

I did suggest an alternative approach which would rename
serial8250_clear_fifos() and split it into 2 variants - one that
disables FIFOs & one that does not, then use the latter in
__do_stop_tx_rs485():
https://lore.kernel.org/lkml/20181213014805.77u5dzydo23cm6fq@pburton-laptop/
However I have no access to the OMAP3 hardware that Marek's patch was
attempting to fix & have heard nothing back with regards to him testing
that approach, so here's a simple revert that fixes the Ingenic JZ4780.
I've marked for stable back to v4.10 presuming that this is how far the
broken patch may be backported, given that this is where commit
2bed8a8e7072 ("Clearing FIFOs in RS485 emulation mode causes subsequent
transmits to break") that it tried to fix was introduced.

[PATCH v2] fs: fix possible Spectre V1 indexing in __close_fd()
by Greg Hackmann
Omer Tripp's analysis of a Spectre V1 gadget in __close_fd():
"1. __close_fd() is reachable via the close() syscall with a
user-controlled fd.
2. If said bounds check is mispredicted, then a user-controlled
address fdt->fd[fd] is obtained then dereferenced, and the value of
a user-controlled address is loaded into the local variable file.
3. file is then passed as an argument to filp_close, where the cache
lines secret + offsetof(f_op) and secret + offsetof(f_mode) are hot
and vulnerable to a timing channel attack."
Address this by using array_index_nospec() to prevent speculation past
the end of current->fdt.

Subject: [PATCH] futex: Cure exit race
Stefan reported, that the glibc tst-robustpi4 test case fails
occasionally. That case creates the following race between
sys_exit() and sys_futex_lock_pi():
CPU0 CPU1
sys_exit() sys_futex()
do_exit() futex_lock_pi()
exit_signals(tsk) No waiters:
tsk->flags |= PF_EXITING; *uaddr == 0x00000PID
mm_release(tsk) Set waiter bit
exit_robust_list(tsk) { *uaddr = 0x80000PID;
Set owner died attach_to_pi_owner() {
*uaddr = 0xC0000000; tsk = get_task(PID);
} if (!tsk->flags & PF_EXITING) {
... attach();
tsk->flags |= PF_EXITPIDONE; } else {
if (!(tsk->flags & PF_EXITPIDONE))
return -EAGAIN;
return -ESRCH; <--- FAIL
}
ESRCH is returned all the way to user space, which triggers the glibc test
case assert. Returning ESRCH unconditionally is wrong here because the user
space value has been changed by the exiting task to 0xC0000000, i.e. the
FUTEX_OWNER_DIED bit is set and the futex PID value has been cleared. This
is a valid state and the kernel has to handle it, i.e. taking the futex.
Cure it by rereading the user space value when PF_EXITING and PF_EXITPIDONE
is set in the task which 'owns' the futex. If the value has changed, let
the kernel retry the operation, which includes all regular sanity checks
and correctly handles the FUTEX_OWNER_DIED case.
If it hasn't changed, then return ESRCH as there is no way to distinguish
this case from malfunctioning user space. This happens when the exiting
task did not have a robust list, the robust list was corrupted or the user
space value in the futex was simply bogus.

Subject: [PATCH] futex: Cure exit race
Stefan reported, that the glibc tst-robustpi4 test case fails
occasionally. That case creates the following race between
sys_exit() and sys_futex_lock_pi():
CPU0 CPU1
sys_exit() sys_futex()
do_exit() futex_lock_pi()
exit_signals(tsk) No waiters:
tsk->flags |= PF_EXITING; *uaddr == 0x00000PID
mm_release(tsk) Set waiter bit
exit_robust_list(tsk) { *uaddr = 0x80000PID;
Set owner died attach_to_pi_owner() {
*uaddr = 0xC0000000; tsk = get_task(PID);
} if (!tsk->flags & PF_EXITING) {
... attach();
tsk->flags |= PF_EXITPIDONE; } else {
if (!(tsk->flags & PF_EXITPIDONE))
return -EAGAIN;
return -ESRCH; <--- FAIL
}
ESRCH is returned all the way to user space, which triggers the glibc test
case assert. Returning ESRCH unconditionally is wrong here because the user
space value has been changed by the exiting task to 0xC0000000, i.e. the
FUTEX_OWNER_DIED bit is set and the futex PID value has been cleared. This
is a valid state and the kernel has to handle it, i.e. taking the futex.
Cure it by rereading the user space value when PF_EXITING and PF_EXITPIDONE
is set in the task which 'owns' the futex. If the value has changed, let
the kernel retry the operation, which includes all regular sanity checks
and correctly handles the FUTEX_OWNER_DIED case.
If it hasn't changed, then return ESRCH as there is no way to distinguish
this case from malfunctioning user space. This happens when the exiting
task did not have a robust list, the robust list was corrupted or the user
space value in the futex was simply bogus.

Subject: [PATCH] ubifs: Handle re-linking of inodes correctly while recovery
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
UBIFS's recovery code strictly assumes that a deleted inode will never
come back, therefore it removes all data which belongs to that inode
as soon it faces an inode with link count 0 in the replay list.
Before O_TMPFILE this assumption was perfectly fine. With O_TMPFILE
it can lead to data loss upon a power-cut.
Consider a journal with entries like:
0: inode X (nlink = 0) /* O_TMPFILE was created */
1: data for inode X /* Someone writes to the temp file */
2: inode X (nlink = 0) /* inode was changed, xattr, chmod, … */
3: inode X (nlink = 1) /* inode was re-linked via linkat() */
Upon replay of entry #2 UBIFS will drop all data that belongs to inode X,
this will lead to an empty file after mounting.
As solution for this problem, scan the replay list for a re-link entry
before dropping data.

[PATCH] memcg, oom: notify on oom killer invocation from the charge path
by Michal Hocko
From: Michal Hocko <mhocko(a)suse.com>
Burt Holzman has noticed that memcg v1 doesn't notify about OOM events
via eventfd anymore. The reason is that 29ef680ae7c2 ("memcg, oom: move
out_of_memory back to the charge path") has moved the oom handling back
to the charge path. While doing so the notification was left behind in
mem_cgroup_oom_synchronize.
Fix the issue by replicating the oom hierarchy locking and the
notification.

I forgot to CC you on the patch sent as a reply to the original bug
report [1] so I am reposting with Ack from Johannes. Burt has confirmed
this is resolving the regression for him [2]. 4.20 is out but I have

[PATCH 0/1] f2fs: fix sanity_check_raw_super on big endian machines
by Martin Blumenstingl
Big endian machines (at least the one I have access to) cannot mount
f2fs filesystems anymore.
This is with Linux 4.14.89 but I suspect that 4.9.144 (and later) is
affected as well.
commit 0cfe75c5b01199 ("f2fs: enhance sanity_check_raw_super() to avoid
potential overflows") treats the "block_count" from struct
f2fs_super_block as 32-bit little endian value instead of a 64-bit
little endian value.
I tested this fix on top of Linux 4.14.49 but it seems that all stable
and mainline kernel versions are affected:
- 4.9.144 and later because 0cfe75c5b01199 was backported there
- 4.14.86 and later because 0cfe75c5b01199 was backported there
- 4.19
- 4.20-rcX

[PATCH] MIPS: math-emu: Write-protect delay slot emulation pages
by Paul Burton
Mapping the delay slot emulation page as both writeable & executable
presents a security risk, in that if an exploit can write to & jump into
the page then it can be used as an easy way to execute arbitrary code.
Prevent this by mapping the page read-only for userland, and using
access_process_vm() with the FOLL_FORCE flag to write to it from
mips_dsemul().
This will likely be less efficient due to copy_to_user_page() performing
cache maintenance on a whole page, rather than a single line as in the
previous use of flush_cache_sigtramp(). However this delay slot
emulation code ought not to be running in any performance critical paths
anyway so this isn't really a problem, and we can probably do better in
copy_to_user_page() anyway in future.
A major advantage of this approach is that the fix is small & simple to
backport to stable kernels.
