2.25.1
From: Waiman Long <[email protected]>
commit 8982ae527fbef170ef298650c15d55a9ccd33973 upstream.
The kzfree() function is normally used to clear some sensitive
information, like encryption keys, in the buffer before freeing it back to
the pool. Memset() is currently used for buffer clearing. However
unlikely, there is still a non-zero probability that the compiler may
choose to optimize away the memory clearing especially if LTO is being
used in the future.
To make sure that this optimization will never happen,
memzero_explicit(), which is introduced in v3.18, is now used in
kzfree() to future-proof it.

2.25.1
From: Marcelo Ricardo Leitner <[email protected]>
[ Upstream commit 471e39df96b9a4c4ba88a2da9e25a126624d7a9c ]
If a socket is set ipv6only, it will still send IPv4 addresses in the
INIT and INIT_ACK packets. This potentially misleads the peer into using
them, which then would cause association termination.
The fix is to not add IPv4 addresses to ipv6only sockets.

Private data passed to iwarp_cm_handler is copied for connection request /
response, but ignored otherwise. If junk is passed, it is stored in the
event and used later in the event processing.
The driver passes an old junk pointer during connection close which leads
to a use-after-free on event processing. Set private data to NULL for
events that don 't have private data.

[ Upstream commit 9208d2863ac689a563b92f2161d8d1e7127d0add ]
cake_handle_diffserv() tries to linearize mac and network header parts of
skb and to make it writable unconditionally. In some cases it leads to full
skb reallocation, which reduces throughput and increases CPU load. Some
measurements of IPv4 forward + NAPT on MIPS router with 580 MHz single-core
CPU was conducted. It appears that on kernel 4.9 skb_try_make_writable()
reallocates skb, if skb was allocated in ethernet driver via so-called
'build skb' method from page cache (it was discovered by strange increase
of kmalloc-2048 slab at first).
Obtain DSCP value via read-only skb_header_pointer() call, and leave
linearization only for DSCP bleaching or ECN CE setting. And, as an
additional optimisation, skip diffserv parsing entirely if it is not needed
by the current configuration.

The micmute LED GPIO has a different polarity to the mute LED GPIO, we

[ Upstream commit 715028460082d07a7ec6fcd87b14b46784346a72 ]
When using ip_set with counters and comment, traffic causes the kernel
to panic on 32-bit ARM:
Alignment trap: not handling instruction e1b82f9f at [<bf01b0dc>]
Unhandled fault: alignment exception (0x221) at 0xea08133c
PC is at ip_set_match_extensions+0xe0/0x224 [ip_set]
The problem occurs when we try to update the 64-bit counters - the
faulting address above is not 64-bit aligned. The problem occurs
due to the way elements are allocated, for example:
set->dsize = ip_set_elem_len(set, tb, 0, 0);
map = ip_set_alloc(sizeof(*map) + elements * set->dsize);
If the element has a requirement for a member to be 64-bit aligned,
and set->dsize is not a multiple of 8, but is a multiple of four,
then every odd numbered elements will be misaligned - and hitting
an atomic64_add() on that element will cause the kernel to panic.
ip_set_elem_len() must return a size that is rounded to the maximum
alignment of any extension field stored in the element. This change
ensures that is the case.

From: David Howells <[email protected]>
[ Upstream commit a2ad7c21ad8cf1ce4ad65e13df1c2a1c29b38ac5 ]
The handling of the receive window size (rwind) from a received ACK packet
is not correct. The rxrpc_input_ackinfo() function currently checks the
current Tx window size against the rwind from the ACK to see if it has
changed, but then limits the rwind size before storing it in the tx_winsize
member and, if it increased, wake up the transmitting process. This means
that if rwind > RXRPC_RXTX_BUFF_SIZE - 1, this path will always be
followed.
Fix this by limiting rwind before we compare it to tx_winsize.
The effect of this can be seen by enabling the rxrpc_rx_rwind_change
tracepoint.

[ Upstream commit 3b4b19721ec652ad2c4fe51dfbe5124212b5f581 ]
Revert fab7772bfbcf ("nvme-multipath: revalidate nvme_ns_head gendisk
in nvme_validate_ns")
When adding a new namespace to the head disk (via nvme_mpath_set_live)
we will see partition scan which triggers I/O on the mpath device node.
This process will usually be triggered from the scan_work which holds
the scan_lock. If I/O blocks (if we got ana change currently have only
available paths but none are accessible) this can deadlock on the head
disk bd_mutex as both partition scan I/O takes it, and head disk revalidation
takes it to check for resize (also triggered from scan_work on a different
path). See trace [1].
The mpath disk revalidation was originally added to detect online disk
size change, but this is no longer needed since commit cb224c3af4df
("nvme: Convert to use set_capacity_revalidate_and_notify") which already
updates resize info without unnecessarily revalidating the disk (the
mpath disk doesn't even implement .revalidate_disk fop).

2.25.1
From: Anton Eidelman <[email protected]>
[ Upstream commit 489dd102a2c7c94d783a35f9412eb085b8da1aa4 ]
When scan_work calls nvme_mpath_add_disk() this holds ana_lock
and invokes nvme_parse_ana_log(), which may issue IO
in device_add_disk() and hang waiting for an accessible path.
While nvme_mpath_set_live() only called when nvme_state_is_live(),
a transition may cause NVME_SC_ANA_TRANSITION and requeue the IO.
In order to recover and complete the IO ana_work on the same ctrl
should be able to update the path state and remove NVME_NS_ANA_PENDING.
The deadlock occurs because scan_work keeps holding ana_lock,
so ana_work hangs [1].
Fix:
Now nvme_mpath_add_disk() uses nvme_parse_ana_log() to obtain a copy
of the ANA group desc, and then calls nvme_update_ns_ana_state() without
holding ana_lock.

[ Upstream commit 6b69040247e14b43419a520f841f2b3052833df9 ]
CIFS implements the fallocate(FALLOC_FL_ZERO_RANGE) with send SMB
ioctl(FSCTL_SET_ZERO_DATA) to server. It just set the range of the
remote file to zero, but local page cache not update, then the data
inconsistent with server, which leads the xfstest generic/008 failed.
So we need to remove the local page caches before send SMB
ioctl(FSCTL_SET_ZERO_DATA) to server. After next read, it will
re-cache it.

commit 4cd9973f9ff69e37dd0ba2bd6e6423f8179c329a upstream.
Patch series "ocfs2: fix nfsd over ocfs2 issues", v2.
This is a series of patches to fix issues on nfsd over ocfs2. patch 1
is to avoid inode removed while nfsd access it patch 2 & 3 is to fix a
panic issue.
This patch (of 4):
When nfsd is getting file dentry using handle or parent dentry of some
dentry, one cluster lock is used to avoid inode removed from other node,
but it still could be removed from local node, so use a rw lock to avoid
this.

commit 97cdcf37b57e3f204be3000b9eab9686f38b4356 upstream.
This fills a hole in softnet data, so no change in structure size.
Also prepares for xmit_more placement in the same spot;
skb->xmit_more will be removed in followup patch.

this error.
The exception code is "bd_len = p[3];", "p" value is ffff88803b8cd000
which belongs to the cache kmalloc-512 of size 512. The "page_address(sg_page(scsi_sglist(scmd)))"
maybe from sg_scsi_ioctl function "buffer" which allocated by kzalloc, so "buffer"
may not page aligned.
This also looks completely buggy on highmem systems and really needs to use a
kmap_atomic. --Christoph Hellwig
To address above bugs, Paolo Bonzini advise to simpler to just make a char array
of size CACHE_MPAGE_LEN+8+8+4-2(or just 64 to make it easy), use sg_copy_to_buffer
to copy from the sglist into the buffer, and workthere.

From: Denis Kirjanov <[email protected]>
[ Upstream commit 2570284060b48f3f79d8f1a2698792f36c385e9a ]
there is a problem with the CWR flag set in an incoming ACK segment
and it leads to the situation when the ECE flag is latched forever
the following packetdrill script shows what happens:
// Stack receives incoming segments with CE set
+0.1 <[ect0] . 11001:12001(1000) ack 1001 win 65535
+0.0 <[ce] . 12001:13001(1000) ack 1001 win 65535
+0.0 <[ect0] P. 13001:14001(1000) ack 1001 win 65535
// Stack repsonds with ECN ECHO
+0.0 >[noecn] . 1001:1001(0) ack 12001
+0.0 >[noecn] E. 1001:1001(0) ack 13001
+0.0 >[noecn] E. 1001:1001(0) ack 14001
// Write a packet
+0.1 write(3, ..., 1000) = 1000
+0.0 >[ect0] PE. 1001:2001(1000) ack 14001
// Pure ACK received
+0.01 <[noecn] W. 14001:14001(0) ack 2001 win 65535
// Since CWR was sent, this packet should NOT have ECE set
+0.1 write(3, ..., 1000) = 1000
+0.0 >[ect0] P. 2001:3001(1000) ack 14001
// but Linux will still keep ECE latched here, with packetdrill
// flagging a missing ECE flag, expecting
// >[ect0] PE. 2001:3001(1000) ack 14001
// in the script
In the situation above we will continue to send ECN ECHO packets
and trigger the peer to reduce the congestion window. To avoid that
we can check CWR on pure ACKs received.
v3:
- Add a sequence check to avoid sending an ACK to an ACK
v2:
- Adjusted the comment
- move CWR check before checking for unacknowledged packets

[ Upstream commit 6a9fb468f1152d6254f49fee6ac28c3cfa3367e5 ]
extent-tree.c has a find_next_key that just walks up the path to find
the next key, but it is used for both the caching stuff and the snapshot
delete stuff. The snapshot deletion stuff is special so it can't really
use btrfs_find_next_key, but the caching thread stuff can. We just need
to fix btrfs_find_next_key to deal with ->skip_locking and then it works
exactly the same as the private find_next_key helper.

commit a24d5072e87457a14023ee1dd3fc8b1e76f899ef upstream.
When runtime suspend was enabled, runtime suspend might happen
when xhci is removing hcd. This might cause kernel panic when hcd
has been freed but runtime pm suspend related handle need to
reference it.

commit 2f02fd3fa13e51713b630164f8a8e5b42de8283b upstream.
The comments in fanotify_group_event_mask() say:
"If the event is on dir/child and this mark doesn't care about
events on dir/child, don't send it!"
Specifically, mount and filesystem marks do not care about events
on child, but they can still specify an ignore mask for those events.
For example, a group that has:
- A mount mark with mask 0 and ignore_mask FAN_OPEN
- An inode mark on a directory with mask FAN_OPEN | FAN_OPEN_EXEC
with flag FAN_EVENT_ON_CHILD
A child file open for exec would be reported to group with the FAN_OPEN
event despite the fact that FAN_OPEN is in ignore mask of mount mark,
because the mark iteration loop skips over non-inode marks for events
on child when calculating the ignore mask.
Move ignore mask calculation to the top of the iteration loop block
before excluding marks for events on dir/child.

commit b3d71abd135e6919ca0b6cab463738472653ddfb upstream.
USB2 devices with LPM enabled may interrupt the system suspend:
[ 932.510475] usb 1-7: usb suspend, wakeup 0
[ 932.510549] hub 1-0:1.0: hub_suspend

[ 932.510593] xhci_hcd 0000:00:14.0: port 8 not suspended
..
[ 932.520323] xhci_hcd 0000:00:14.0: Port change event, 1-7, id 7, portsc: 0x400e03
..
[ 932.591405] PM: pci_pm_suspend(): hcd_pci_suspend+0x0/0x30 returns -16
[ 932.591414] PM: dpm_run_callback(): pci_pm_suspend+0x0/0x160 returns -16
[ 932.591418] PM: Device 0000:00:14.0 failed to suspend async: error -16
During system suspend, USB core will let HC suspends the device if it
doesn't have remote wakeup enabled and doesn't have any children.
However, from the log above we can see that the usb 1-7 doesn't get bus
suspended due to not in U0. After a while the port finished U2 -> U0
transition, interrupts the suspend process.
The observation is that after disabling LPM, port doesn't transit to U0
immediately and can linger in U2. xHCI spec 4.23.5.2 states that the
maximum exit latency for USB2 LPM should be BESL + 10us. The BESL for
the affected device is advertised as 400us, which is still not enough
based on my testing result.
So let's use the maximum permitted latency, 10000, to poll for U0
status to solve the issue.

[ Upstream commit f2f02ebd8f3833626642688b2d2c6a7b3c141fa9 ]
When cc-option and friends evaluate compiler flags, the temporary file
$$TMP is created as an output object, and automatically cleaned up.
The actual file path of $$TMP is .<pid>.tmp, here <pid> is the process
ID of $(shell ...) invoked from cc-option. (Please note $$$$ is the
escape sequence of $$).
Such garbage files are cleaned up in most cases, but some compiler flags
create additional output files.
For example, -gsplit-dwarf creates a .dwo file.
When CONFIG_DEBUG_INFO_SPLIT=y, you will see a bunch of .<pid>.dwo files
left in the top of build directories. You may not notice them unless you
do 'ls -a', but the garbage files will increase every time you run 'make'.
This commit changes the temporary object path to .tmp_<pid>/tmp, and
removes .tmp_<pid> directory when exiting. Separate build artifacts such
as *.dwo will be cleaned up all together because their file paths are
usually determined based on the base name of the object.
Another example is -ftest-coverage, which outputs the coverage data into
<base-name-of-object>.gcno

commit 3c597282887fd55181578996dca52ce697d985a5 upstream.
Hongyu reported "id != index" in z_erofs_onlinepage_fixup() with
specific aarch64 environment easily, which wasn't shown before.
After digging into that, I found that high 32 bits of page->private
was set to 0xaaaaaaaa rather than 0 (due to z_erofs_onlinepage_init
behavior with specific compiler options). Actually we only use low
32 bits to keep the page information since page->private is only 4
bytes on most 32-bit platforms. However z_erofs_onlinepage_fixup()
uses the upper 32 bits by mistake.
Let's fix it now.

[ Upstream commit db7202dec92e6caa2706c21d6fc359af318bde2e ]
The eth_addr member is passed to ether_addr functions that require
2-byte alignment, therefore the member must be properly aligned
to avoid unaligned accesses.
The problem is in place since the initial merge of multicast to unicast:

When /sys/firmware/acpi/pm_profile is read, sysfs_kf_seq_show is called,
which in turn calls kobj_attr_show, which gets the ->show callback
member by calling container_of on attr (casting it to struct
kobj_attribute) then calls it.
There is a CFI violation because pm_profile_attr is of type
struct device_attribute but kobj_attr_show calls ->show expecting it
to be from struct kobj_attribute. CFI checking ensures that function
pointer types match when doing indirect calls. Fix pm_profile_attr to
be defined in terms of kobj_attribute so there is no violation or
mismatch.

2.25.1
From: "Steven Rostedt (VMware)" <[email protected]>
commit 097350d1c6e1f5808cae142006f18a0bbc57018d upstream.
Currently the ring buffer makes events that happen in interrupts that preempt
another event have a delta of zero. (Hopefully we can change this soon). But
this is to deal with the races of updating a global counter with lockless
and nesting functions updating deltas.
With the addition of absolute time stamps, the time extend didn't follow
this rule. A time extend can happen if two events happen longer than 2^27
nanoseconds appart, as the delta time field in each event is only 27 bits.
If that happens, then a time extend is injected with 2^59 bits of
nanoseconds to use (18 years). But if the 2^27 nanoseconds happen between
two events, and as it is writing the event, an interrupt triggers, it will
see the 2^27 difference as well and inject a time extend of its own. But a
recent change made the time extend logic not take into account the nesting,
and this can cause two time extend deltas to happen moving the time stamp
much further ahead than the current time. This gets all reset when the ring
buffer moves to the next page, but that can cause time to appear to go
backwards.
This was observed in a trace-cmd recording, and since the data is saved in a
file, with trace-cmd report --debug, it was possible to see that this indeed
did happen!

From: Olga Kornievskaia <[email protected]>
commit d03727b248d0dae6199569a8d7b629a681154633 upstream.
Figuring out the root case for the REMOVE/CLOSE race and
suggesting the solution was done by Neil Brown.
Currently what happens is that direct IO calls hold a reference
on the open context which is decremented as an asynchronous task
in the nfs_direct_complete(). Before reference is decremented,
control is returned to the application which is free to close the
file. When close is being processed, it decrements its reference
on the open_context but since directIO still holds one, it doesn't
sent a close on the wire. It returns control to the application
which is free to do other operations. For instance, it can delete a
file. Direct IO is finally releasing its reference and triggering
an asynchronous close. Which races with the REMOVE. On the server,
REMOVE can be processed before the CLOSE, failing the REMOVE with
EACCES as the file is still opened.

[ Upstream commit 6f1cf5257acc6e6242ddf2f52bc7912aed77b79f ]
PFUZE100_SWB_REG is not proper for sw1a/sw2, because enable_mask/enable_reg
is not correct. On PFUZE3000, sw1a/sw2 should be the same as sw1a/sw2 on
pfuze100 except that voltages are not linear, so add new PFUZE3000_SW_REG
and pfuze3000_sw_regulator_ops which like the non-linear PFUZE100_SW_REG
and pfuze100_sw_regulator_ops.

The system in question uses ALC285, and it uses GPIO 0x04 to control its
mute LED.
The mic mute LED can be controlled by GPIO 0x01, however the system uses
DMIC so we should use that to control mic mute LED.

[ Upstream commit ccd7c7ce167a21dbf2b698ffcf00f11d96d44f9b ]
25ms sleep cycles in waiting for PF response are excessive and may lead
to different timeout failures.
Start to wait with short udelays, and in most cases polling will end
here. If the time was not sufficient, switch to msleeps.
usleep_range() may go far beyond 100us depending on platform and tick
configuration, hence atomic udelays for consistency.
Also add explicit DMA barriers since 'done' always comes from a shared
request-response DMA pool, and note that in the comment nearby.

[ Upstream commit 873e5a763d604c32988c4a78913a8dab3862d2f9 ]
When strace wants to update the syscall number, it sets GPR2
to the desired number and updates the GPR via PTRACE_SETREGSET.
It doesn't update regs->int_code which would cause the old syscall
executed on syscall restart. As we cannot change the ptrace ABI and
don't have a field for the interruption code, check whether the tracee
is in a syscall and the last instruction was svc. In that case assume
that the tracer wants to update the syscall number and copy the GPR2
value to regs->int_code.

From: Masami Hiramatsu <[email protected]>
commit 6784beada631800f2c5afd567e5628c843362cee upstream.
Fix the event trigger to accept redundant spaces in
the trigger input.
For example, these return -EINVAL
echo " traceon" > events/ftrace/print/trigger
echo "traceon if common_pid == 0" > events/ftrace/print/trigger
echo "disable_event:kmem:kmalloc " > events/ftrace/print/trigger
But these are hard to find what is wrong.
To fix this issue, use skip_spaces() to remove spaces
in front of actual tokens, and set NULL if there is no
token.

From: Vincenzo Frascino <[email protected]>
[ Upstream commit 478237a595120a18e9b52fd2c57a6e8b7a01e411 ]
clock_getres in the vDSO library has to preserve the same behaviour
of posix_get_hrtimer_res().
In particular, posix_get_hrtimer_res() does:
sec = 0;
ns = hrtimer_resolution;
and hrtimer_resolution depends on the enablement of the high
resolution timers that can happen either at compile or at run time.
Fix the s390 vdso implementation of clock_getres keeping a copy of
hrtimer_resolution in vdso data and using that directly.

This is likely a copy'n'paste mistake. The amount of ILT lines to
reserve for a single VF was being multiplied by the total VFs count.
This led to a huge redundancy in reservation and potential lines
drainouts.

[ Upstream commit dafabb6590cb15f300b77c095d50312e2c7c8e0f ]
In the datapath, the ip6gre_tunnel_lookup() is used and it internally uses
fallback tunnel device pointer, which is fb_tunnel_dev.
This pointer variable should be set to NULL when a fb interface is deleted.
But there is no routine to set fb_tunnel_dev pointer to NULL.
So, this pointer will be still used after interface is deleted and
it eventually results in the use-after-free problem.
Test commands:
ip netns add A
ip netns add B
ip link add eth0 type veth peer name eth1
ip link set eth0 netns A
ip link set eth1 netns B
ip netns exec A ip link set lo up
ip netns exec A ip link set eth0 up
ip netns exec A ip link add ip6gre1 type ip6gre local fc:0::1 \
remote fc:0::2
ip netns exec A ip -6 a a fc:100::1/64 dev ip6gre1
ip netns exec A ip link set ip6gre1 up
ip netns exec A ip -6 a a fc:0::1/64 dev eth0
ip netns exec A ip link set ip6gre0 up
ip netns exec B ip link set lo up
ip netns exec B ip link set eth1 up
ip netns exec B ip link add ip6gre1 type ip6gre local fc:0::2 \
remote fc:0::1
ip netns exec B ip -6 a a fc:100::2/64 dev ip6gre1
ip netns exec B ip link set ip6gre1 up

ip netns exec B ip link set ip6gre0 up
ip netns exec A ping fc:100::2 -s 60000 &

If the function platform_get_irq() failed, the negative value
returned will not be detected here. So fix error handling in
exynos_ehci_probe(). And when get irq failed, the function
platform_get_irq() logs an error message, so remove redundant
message here.

The argument passed to cmpxchg is not guaranteed to be sign
extended, but lr.w sign extends on RV64I. This makes cmpxchg
fail on clang built kernels when __old is negative.
To fix this, we just cast __old to long which sign extends on
RV64I. With this fix, clang built RISC-V kernels now boot.

[ Upstream commit 662051215c758ae8545451628816204ed6cd372d ]
Back in 2013, we made a change that broke fast retransmit
for non SACK flows.
Indeed, for these flows, a sender needs to receive three duplicate
ACK before starting fast retransmit. Sending ACK with different
receive window do not count.
Even if enabling SACK is strongly recommended these days,
there still are some cases where it has to be disabled.
Not increasing the window seems better than having to
rely on RTO.
After the fix, following packetdrill test gives :
// Initialize connection
0 socket(..., SOCK_STREAM, IPPROTO_TCP) = 3
+0 setsockopt(3, SOL_SOCKET, SO_REUSEADDR, [1], 4) = 0
+0 bind(3, ..., ...) = 0

commit 9277f8334ffc719fe922d776444d6e4e884dbf30 upstream.
In the ocfs2 disk layout, slot number is 16 bits, but in ocfs2
implementation, slot number is 32 bits. Usually this will not cause any
issue, because slot number is converted from u16 to u32, but
OCFS2_INVALID_SLOT was defined as -1, when an invalid slot number from
disk was obtained, its value was (u16)-1, and it was converted to u32.
Then the following checking in get_local_system_inode will be always
skipped:
static struct inode **get_local_system_inode(struct ocfs2_super *osb,

[ Upstream commit e0d17c842c0f824fd4df9f4688709fc6907201e1 ]
As per the table 4.4 of version "20190608-Priv-MSU-Ratified" of the
RISC-V instruction set manual[0], the PTE permission bit combination of
"write+exec only" is reserved for future use. Hence, don't allow such
mapping request in mmap call.
An issue is been reported by David Abdurachmanov, that while running
stress-ng with "sysbadaddr" argument, RCU stalls are observed on RISC-V
specific kernel.
This issue arises when the stress-sysbadaddr request for pages with
"write+exec only" permission bits and then passes the address obtain
from this mmap call to various system call. For the riscv kernel, the
mmap call should fail for this particular combination of permission bits
since it's not valid.

qed_chain_get_element_left{,_u32} returned 0 when the difference
between producer and consumer page count was equal to the total
page count.
Fix this by conditional expanding of producer value (vs
unconditional). This allowed to eliminate normalizaton against
total page count, which was the cause of this bug.
Misc: replace open-coded constants with common defines.

From: Shengjiu Wang <[email protected]>
[ Upstream commit ed1220df6e666500ebf58c4f2fccc681941646fb ]
For mono channel, SSI will switch to Normal mode.
In Normal mode and Network mode, the Word Length Control bits
control the word length divider in clock generator, which is
different with I2S Master mode (the word length is fixed to
32bit), it should be the value of params_width(hw_params).
The condition "slots == 2" is not good for I2S Master mode,
because for Network mode and Normal mode, the slots can also
be 2. Then we need to use (ssi->i2s_net & SSI_SCR_I2S_MODE_MASK)
to check if it is I2S Master mode.
So we refine the formula for mono channel, otherwise there
will be sound issue for S24_LE.

[ Upstream commit c27075772d1f1c8aaf276db9943b35adda8a8b65 ]
In a previous fix, I changed the condition on which the timeout of an
IRQ is reached from:
if (!ret)
into:
if (ret && !pending)
While having a non-zero return code is usual in the Linux kernel, here
ret comes from a wait_for_completion_timeout() which returns 0 when
the waiting period is too long.
Hence, the revised condition should be:
if (!ret && !pending)
The faulty patch did not produce any error because of the !pending
condition so this change is finally purely cosmetic and does not
change the actual driver behavior.

The -EINVAL error comes from the following chain of function calls:
__btrfs_cow_block() <-- aborts the transaction
btrfs_reloc_cow_block()
replace_file_extents()
get_new_location() <-- returns -EINVAL
When relocating a data block group, for each allocated extent of the block
group, we preallocate another extent (at prealloc_file_extent_cluster()),
associated with the data relocation inode, and then dirty all its pages.
These preallocated extents have, and must have, the same size that extents
from the data block group being relocated have.
Later before we start the relocation stage that updates pointers (bytenr
field of file extent items) to point to the the new extents, we trigger
writeback for the data relocation inode. The expectation is that writeback
will write the pages to the previously preallocated extents, that it
follows the NOCOW path. That is generally the case, however, if a scrub
is running it may have turned the block group that contains those extents
into RO mode, in which case writeback falls back to the COW path.
However in the COW path instead of allocating exactly one extent with the
expected size, the allocator may end up allocating several smaller extents
due to free space fragmentation - because we tell it at cow_file_range()
that the minimum allocation size can match the filesystem's sector size.
This later breaks the relocation's expectation that an extent associated
to a file extent item in the data relocation inode has the same size as
the respective extent pointed by a file extent item in another tree - in
this case the extent to which the relocation inode poins to is smaller,
causing relocation.c:get_new_location() to return -EINVAL.
For example, if we are relocating a data block group X that has a logical
address of X and the block group has an extent allocated at the logical
address X + 128KiB with a size of 64KiB:
1) At prealloc_file_extent_cluster() we allocate an extent for the data
relocation inode with a size of 64KiB and associate it to the file
offset 128KiB (X + 128KiB - X) of the data relocation inode. This
preallocated extent was allocated at block group Z;
2) A scrub running in parallel turns block group Z into RO mode and
starts scrubing its extents;
3) Relocation triggers writeback for the data relocation inode;
4) When running delalloc (btrfs_run_delalloc_range()), we try first the
NOCOW path because the data relocation inode has BTRFS_INODE_PREALLOC
set in its flags. However, because block group Z is in RO mode, the
NOCOW path (run_delalloc_nocow()) falls back into the COW path, by
calling cow_file_range();
5) At cow_file_range(), in the first iteration of the while loop we call
btrfs_reserve_extent() to allocate a 64KiB extent and pass it a minimum
allocation size of 4KiB (fs_info->sectorsize). Due to free space
fragmentation, btrfs_reserve_extent() ends up allocating two extents
of 32KiB each, each one on a different iteration of that while loop;
6) Writeback of the data relocation inode completes;
7) Relocation proceeds and ends up at relocation.c:replace_file_extents(),
with a leaf which has a file extent item that points to the data extent
from block group X, that has a logical address (bytenr) of X + 128KiB
and a size of 64KiB. Then it calls get_new_location(), which does a
lookup in the data relocation tree for a file extent item starting at
offset 128KiB (X + 128KiB - X) and belonging to the data relocation
inode. It finds a corresponding file extent item, however that item
points to an extent that has a size of 32KiB, which doesn't match the
expected size of 64KiB, resuling in -EINVAL being returned from this
function and propagated up to __btrfs_cow_block(), which aborts the
current transaction.
To fix this make sure that at cow_file_range() when we call the allocator
we pass it a minimum allocation size corresponding the desired extent size
if the inode belongs to the data relocation tree, otherwise pass it the
filesystem's sector size as the minimum allocation size.

[ Upstream commit 9cf28e41f9f768791f54ee18333239fda6927ed8 ]
While testing the recent suspend and resume regressions I noticed that
duovero can still end up losing edge gpio interrupts on runtime
suspend. This causes NFSroot easily stopping working after resume on
duovero.
Let's fix the issue by using gpio level interrupts for smsc as then
the gpio interrupt state is seen by the gpio controller on resume.

John reported screaming irq caused by rt1711h when system boot[1],
this is because irq request is done before tcpci_register_port(),
so the chip->tcpci has not been setup, irq handler is entered but
can't do anything, this patch is to address this by moving the irq
request after tcpci_register_port().

@subbuf is an output parameter of xdr_buf_subsegment(). A survey of
call sites shows that @subbuf is always uninitialized before
xdr_buf_segment() is invoked by callers.
There are some execution paths through xdr_buf_subsegment() that do
not set all of the fields in @subbuf, leaving some pointer fields
containing garbage addresses. Subsequent processing of that buffer
then results in a page fault.

[ Upstream commit d0c7feaf87678371c2c09b3709400be416b2dc62 ]
We recently used fuzz(hydra) to test XFS and automatically generate
tmp.img(XFS v5 format, but some metadata is wrong)
xfs_repair information(just one AG):
agf_freeblks 0, counted 3224 in ag 0
agf_longest 536874136, counted 3224 in ag 0
sb_fdblocks 613, counted 3228
Test as follows:
mount tmp.img tmpdir
cp file1M tmpdir
sync
In 4.19-stable, sync will stuck, the reason is:
xfs_mountfs
xfs_check_summary_counts
if ((!xfs_sb_version_haslazysbcount(&mp->m_sb) ||
XFS_LAST_UNMOUNT_WAS_CLEAN(mp)) &&
!xfs_fs_has_sickness(mp, XFS_SICK_FS_COUNTERS))
return 0; -->just return, incore sb_fdblocks still be 613
xfs_initialize_perag_data
cp file1M tmpdir -->ok(write file to pagecache)
sync -->stuck(write pagecache to disk)
xfs_map_blocks
xfs_iomap_write_allocate
while (count_fsb != 0) {
nimaps = 0;
while (nimaps == 0) { --> endless loop
nimaps = 1;
xfs_bmapi_write(..., &nimaps) --> nimaps becomes 0 again
xfs_bmapi_write
xfs_bmap_alloc
xfs_bmap_btalloc
xfs_alloc_vextent
xfs_alloc_fix_freelist
xfs_alloc_space_available -->fail(agf_freeblks is 0)
In linux-next, sync not stuck, cause commit c2b3164320b5 ("xfs:
use the latest extent at writeback delalloc conversion time") remove
the above while, dmesg is as follows:
[ 55.250114] XFS (loop0): page discard on page ffffea0008bc7380, inode 0x1b0c, offset 0.
Users do not know why this page is discard, the better soultion is:
1. Like xfs_repair, make sure sb_fdblocks is equal to counted
(xfs_initialize_perag_data did this, who is not called at this mount)
2. Add agf verify, if fail, will tell users to repair
This patch use the second soultion.

[ Upstream commit 20d1f2d1b024f6be199a3bedf1578a1d21592bc5 ]
When commit 474ea9cafc45 ("net: bcmgenet: correctly pad short
packets") added the call to skb_padto() it should have been
located before the nr_frags parameter was read since that value
could be changed when padding packets with lengths between 55
and 59 bytes (inclusive).
The use of a stale nr_frags value can cause corruption of the
pad data when tx-scatter-gather is enabled. This corruption of
the pad can cause invalid checksum computation when hardware
offload of tx-checksum is also enabled.
Since the original reason for the padding was corrected by
commit 7dd399130efb ("net: bcmgenet: fix skb_len in
bcmgenet_xmit_single()") we can remove the software padding all
together and make use of hardware padding of short frames as
long as the hardware also always appends the FCS value to the
frame.

commit 1ddcb71a3edf0e1682b6e056158e4c4b00325f66 upstream.
A Synopsys USB2.0 core used in Huawei Kunpeng920 SoC has a bug which
might cause the host controller not issuing ping.
Bug description:
After indicating an Interrupt on Async Advance, the software uses the
doorbell mechanism to delete the Next Link queue head of the last
executed queue head. At this time, the host controller still references
the removed queue head(the queue head is NULL). NULL reference causes
the host controller to lose the USB device.
Solution:
After deleting the Next Link queue head, when has_synopsys_hc_bug set
to 1，the software can write one of the valid queue head addresses to
the ASYNCLISTADDR register to allow the host controller to get
the valid queue head. in order to solve that problem, this patch set
the flag for Huawei Kunpeng920
There are detailed instructions and solutions in this patch:

[ Upstream commit ba61539c6ae57f4146284a5cb4f7b7ed8d42bf45 ]
In the datapath, the ip_tunnel_lookup() is used and it internally uses
fallback tunnel device pointer, which is fb_tunnel_dev.
This pointer variable should be set to NULL when a fb interface is deleted.
But there is no routine to set fb_tunnel_dev pointer to NULL.
So, this pointer will be still used after interface is deleted and
it eventually results in the use-after-free problem.
Test commands:
ip netns add A
ip netns add B
ip link add eth0 type veth peer name eth1
ip link set eth0 netns A
ip link set eth1 netns B
ip netns exec A ip link set lo up
ip netns exec A ip link set eth0 up
ip netns exec A ip link add gre1 type gre local 10.0.0.1 \
remote 10.0.0.2
ip netns exec A ip link set gre1 up
ip netns exec A ip a a 10.0.100.1/24 dev gre1
ip netns exec A ip a a 10.0.0.1/24 dev eth0
ip netns exec B ip link set lo up
ip netns exec B ip link set eth1 up
ip netns exec B ip link add gre1 type gre local 10.0.0.2 \

If the i2c bus driver ignores the I2C_M_RECV_LEN flag (as some of
them do), it is possible for an I2C_SMBUS_BLOCK_DATA read issued
on some random device to return an arbitrary value in the first
byte (and nothing else). When this happens, i2c_smbus_xfer_emulated()
will happily write past the end of the supplied data buffer, thus
causing Bad Things to happen. To prevent this, check the size
before copying the data block and return an error if it is too large.

[ Upstream commit 1b0b283648163dae2a214ca28ed5a99f62a77319 ]
We use one blktrace per request_queue, that means one per the entire
disk. So we cannot run one blktrace on say /dev/vda and then /dev/vda1,
or just two calls on /dev/vda.
We check for concurrent setup only at the very end of the blktrace setup though.
If we try to run two concurrent blktraces on the same block device the
second one will fail, and the first one seems to go on. However when
one tries to kill the first one one will see things like this:
The kernel will show these:
```
debugfs: File 'dropped' in directory 'nvme1n1' already present!
debugfs: File 'msg' in directory 'nvme1n1' already present!
debugfs: File 'trace0' in directory 'nvme1n1' already present!
``
And userspace just sees this error message for the second call:
```
blktrace /dev/nvme1n1
BLKTRACESETUP(2) /dev/nvme1n1 failed: 5/Input/output error
```
The first userspace process #1 will also claim that the files
were taken underneath their nose as well. The files are taken
away form the first process given that when the second blktrace
fails, it will follow up with a BLKTRACESTOP and BLKTRACETEARDOWN.
This means that even if go-happy process #1 is waiting for blktrace
data, we *have* been asked to take teardown the blktrace.
This can easily be reproduced with break-blktrace [0] run_0005.sh test.
Just break out early if we know we're already going to fail, this will
prevent trying to create the files all over again, which we know still
exist.

[ Upstream commit 0041cd5a50442db6e456b145892a0eaf2dff061f ]
When preallocated service calls are being discarded, they're passed to
->discard_new_call() to have the caller clean up any attached higher-layer
preallocated pieces before being marked completed. However, the act of
marking them completed now invokes the call's notification function - which
causes a problem because that function might assume that the previously
freed pieces of memory are still there.
Fix this by setting a dummy notification function on the socket after
calling ->discard_new_call().
This results in the following kasan message when the kafs module is
removed.

[ Upstream commit e869e7a17798d85829fa7d4f9bbe1eebd4b2d3f6 ]
Using a AX88179 device (0b95:1790), I see two bytes of appended data on
every RX packet. For example, this 48-byte ping, using 0xff as a
payload byte:
04:20:22.528472 IP 192.168.1.1 > 192.168.1.2: ICMP echo request, id 2447, seq 1, length 64
0x0000: 000a cd35 ea50 000a cd35 ea4f 0800 4500
0x0010: 0054 c116 4000 4001 f63e c0a8 0101 c0a8
0x0020: 0102 0800 b633 098f 0001 87ea cd5e 0000
0x0030: 0000 dcf2 0600 0000 0000 ffff ffff ffff
0x0040: ffff ffff ffff ffff ffff ffff ffff ffff
0x0050: ffff ffff ffff ffff ffff ffff ffff ffff
0x0060: ffff 961f
Those last two bytes - 96 1f - aren't part of the original packet.
In the ax88179 RX path, the usbnet rx_fixup function trims a 2-byte
'alignment pseudo header' from the start of the packet, and sets the
length from a per-packet field populated by hardware. It looks like that
length field *includes* the 2-byte header; the current driver assumes
that it's excluded.
This change trims the 2-byte alignment header after we've set the packet
length, so the resulting packet length is correct. While we're moving
the comment around, this also fixes the spelling of 'pseudo'.

EP_STATE_MASK should be 0x7 instead of 0xf
xhci spec 6.2.3 shows that the EP state field in the endpoint context data
structure consist of bits [2:0].
The old value included a bit from the next field which fortunately is a
RsvdZ region. So hopefully this hasn't caused too much harm

From: Filipe Manana <[email protected]>
commit 4b1946284dd6641afdb9457101056d9e6ee6204c upstream.
If we attempt to write to prealloc extent located after eof using a
RWF_NOWAIT write, we always fail with -EAGAIN.
We do actually check if we have an allocated extent for the write at
the start of btrfs_file_write_iter() through a call to check_can_nocow(),
but later when we go into the actual direct IO write path we simply
return -EAGAIN if the write starts at or beyond EOF.
Trivial to reproduce:
$ mkfs.btrfs -f /dev/sdb
$ mount /dev/sdb /mnt
$ touch /mnt/foo
$ chattr +C /mnt/foo
$ xfs_io -d -c "pwrite -S 0xab 0 64K" /mnt/foo
wrote 65536/65536 bytes at offset 0
64 KiB, 16 ops; 0.0004 sec (135.575 MiB/sec and 34707.1584 ops/sec)
$ xfs_io -c "falloc -k 64K 1M" /mnt/foo
$ xfs_io -d -c "pwrite -N -V 1 -S 0xfe -b 64K 64K 64K" /mnt/foo
pwrite: Resource temporarily unavailable
On xfs and ext4 the write succeeds, as expected.
Fix this by removing the wrong check at btrfs_direct_IO().

[ Upstream commit b344579ca8478598937215f7005d6c7b84d28aee ]
Mirja Kuehlewind reported a bug in Linux TCP CUBIC Hystart, where
Hystart HYSTART_DELAY mechanism can exit Slow Start spuriously on an
ACK when the minimum rtt of a connection goes down. From inspection it
is clear from the existing code that this could happen in an example
like the following:
o The first 8 RTT samples in a round trip are 150ms, resulting in a
curr_rtt of 150ms and a delay_min of 150ms.
o The 9th RTT sample is 100ms. The curr_rtt does not change after the
first 8 samples, so curr_rtt remains 150ms. But delay_min can be
lowered at any time, so delay_min falls to 100ms. The code executes
the HYSTART_DELAY comparison between curr_rtt of 150ms and delay_min
of 100ms, and the curr_rtt is declared far enough above delay_min to
force a (spurious) exit of Slow start.
The fix here is simple: allow every RTT sample in a round trip to
lower the curr_rtt.

[ Upstream commit 740797ce3a124b7dd22b7fb832d87bc8fba1cf6f ]
syzbot reported the following warning:
WARNING: CPU: 1 PID: 6351 at kernel/sched/deadline.c:628
enqueue_task_dl+0x22da/0x38a0 kernel/sched/deadline.c:1504
At deadline.c:628 we have:
623 static inline void setup_new_dl_entity(struct sched_dl_entity *dl_se)
624 {
625 struct dl_rq *dl_rq = dl_rq_of_se(dl_se);
626 struct rq *rq = rq_of_dl_rq(dl_rq);
627
628 WARN_ON(dl_se->dl_boosted);
629 WARN_ON(dl_time_before(rq_clock(rq), dl_se->deadline));
[...]
}
Which means that setup_new_dl_entity() has been called on a task
currently boosted. This shouldn't happen though, as setup_new_dl_entity()
is only called when the 'dynamic' deadline of the new entity
is in the past w.r.t. rq_clock and boosted tasks shouldn't verify this
condition.
Digging through the PI code I noticed that what above might in fact happen
if an RT tasks blocks on an rt_mutex hold by a DEADLINE task. In the
first branch of boosting conditions we check only if a pi_task 'dynamic'
deadline is earlier than mutex holder's and in this case we set mutex
holder to be dl_boosted. However, since RT 'dynamic' deadlines are only
initialized if such tasks get boosted at some point (or if they become
DEADLINE of course), in general RT 'dynamic' deadlines are usually equal
to 0 and this verifies the aforementioned condition.
Fix it by checking that the potential donor task is actually (even if
temporary because in turn boosted) running at DEADLINE priority before
using its 'dynamic' deadline value.

it could result in use after free of rmpp_recv, as decribed below:

[ Upstream commit e89df5c4322c1bf495f62d74745895b5fd2a4393 ]
There is a race condition exist during termination. The path is
alx_stop and then alx_remove. An alx_schedule_link_check could be called
before alx_stop by interrupt handler and invoke alx_link_check later.
Alx_stop frees the napis, and alx_remove cancels any pending works.
If any of the work is scheduled before termination and invoked before
alx_remove, a null-ptr-deref occurs because both expect alx->napis[i].
This patch fix the race condition by moving cancel_work_sync functions
before alx_free_napis inside alx_stop. Because interrupt handler can call
alx_schedule_link_check again, alx_free_irq is moved before
cancel_work_sync calls too.

Back in commit f60e5990d9c1 ("ipv6: protect skb->sk accesses
from recursive dereference inside the stack") Hannes added code
so that IPv6 stack would not trust skb->sk for typical cases
where packet goes through 'standard' xmit path (__dev_queue_xmit())
Alas af_packet had a dev_direct_xmit() path that was not
dealing yet with xmit_recursion level.
Also change sk_mc_loop() to dump a stack once only.

2.25.1
From: Steffen Maier <[email protected]>
commit 936e6b85da0476dd2edac7c51c68072da9fb4ba2 upstream.
Suppose that, for unrelated reasons, FSF requests on behalf of recovery are
very slow and can run into the ERP timeout.
In the case at hand, we did adapter recovery to a large degree. However
due to the slowness a LUN open is pending so the corresponding fc_rport
remains blocked. After fast_io_fail_tmo we trigger close physical port
recovery for the port under which the LUN should have been opened. The new
higher order port recovery dismisses the pending LUN open ERP action and
dismisses the pending LUN open FSF request. Such dismissal decouples the
ERP action from the pending corresponding FSF request by setting
zfcp_fsf_req->erp_action to NULL (among other things)
[zfcp_erp_strategy_check_fsfreq()].
If now the ERP timeout for the pending open LUN request runs out, we must
not use zfcp_fsf_req->erp_action in the ERP timeout handler. This is a
problem since v4.15 commit 75492a51568b ("s390/scsi: Convert timers to use
timer_setup()"). Before that we intentionally only passed zfcp_erp_action
as context argument to zfcp_erp_timeout_handler().
Note: The lifetime of the corresponding zfcp_fsf_req object continues until
a (late) response or an (unrelated) adapter recovery.
Just like the regular response path ignores dismissed requests
[zfcp_fsf_req_complete() => zfcp_fsf_protstatus_eval() => return early] the
ERP timeout handler now needs to ignore dismissed requests. So simply
return early in the ERP timeout handler if the FSF request is marked as
dismissed in its status flags. To protect against the race where
zfcp_erp_strategy_check_fsfreq() dismisses and sets
zfcp_fsf_req->erp_action to NULL after our previous status flag check,
return early if zfcp_fsf_req->erp_action is NULL. After all, the former
ERP action does not need to be woken up as that was already done as part of
the dismissal above [zfcp_erp_action_dismiss()].
This fixes the following panic due to kernel page fault in IRQ context:
Unable to handle kernel pointer dereference in virtual kernel address space
Failing address: 0000000000000000 TEID: 0000000000000483

According to changelog, this is not known to fix a bug. Why is it
needed in stable?

Unfortunately, v4.19-stable does not contain cb224c3af4df. According

For the record, I'm not fan of this one. It is ABI change, not a
bugfix.
Yes, it makes kernel interface "easier to use". It also changes
interface in the middle of stable series, and if people start relying
on new interface and start putting extra spaces, they'll get nasty
surprise when they move code to the older kernel.

0, 0);
...
return status;
}
When ocfs2_nfs_sync_lock() returns error, caller can not know if the
lock was taken or not.
ocfs2_get_dentry() for example will not call ocfs2_nfs_sync_unlock()
if sync_lock() failed, resulting in lock imbalance if
ocfs2_cluster_lock() fails.
(Totally untested).

You are absolutely right,
The reference commit is a part of the series:
78317c5d58e6 ("scsi: Convert to use set_capacity_revalidate_and_notify")
cb224c3af4df ("nvme: Convert to use set_capacity_revalidate_and_notify")
3cbc28bb902b ("xen-blkfront.c: Convert to use
set_capacity_revalidate_and_notify")
662155e2898d ("virtio_blk.c: Convert to use
set_capacity_revalidate_and_notify")
e598a72faeb5 ("block/genhd: Notify udev about capacity change")
It would be cool if they are cherry picked, although they don't qualify
as stable patches per se...

Right you are.
And your patch looks sane:

If the issue is a lifetime thing (like that commit says), the proper
model isn't a lock, but a refcount.
Oh well. Junxiao?

If an interface changes anywhere that breaks userspace, it needs to be
not done, stable kernels are not an issue here or not.
Does this do that? It looks to me that this actually fixes things
instead.

We promise users that they can upgrade their kernels and we won't be
breaking any of their usecases no matter what. However, if they choose
to downgrade their kernels then all bets are off.

I'm not saying it is a regression; I'd scream way more if that was the
case. I'm saying it is nowhere near a fix.
We really don't want userspace doing:

Because it does not work on older kernels. It will work on 4.19.131
and break on 5.6.19.

There is a block number embedded in nfs file handle, to verify it's an
inode, need acquire this nfs_sync_lock global lock to avoid any inode
removed from local node and other nodes in the cluster, before this
verify done, seemed no way to use a refcount.

Moving to an EOL kernel is very much unsupported.
