c4adf3557d net: cipso: fix warnings in netlbl_cipsov4_add_std
[ Upstream commit 8ca34a13f7 ]

Syzbot reported warning in netlbl_cipsov4_add(). The
problem was in too big doi_def->map.std->lvl.local_size
passed to kcalloc(). Since this value comes from userpace there is
no need to warn if value is not correct.

The same problem may occur with other kcalloc() calls in
this function, so, I've added __GFP_NOWARN flag to all
kcalloc() calls there.

c23f890c00 tcp: seq_file: Avoid skipping sk during tcp_seek_last_pos
[ Upstream commit 525e2f9fd0 ]

st->bucket stores the current bucket number.
st->offset stores the offset within this bucket that is the sk to be
seq_show().  Thus, st->offset only makes sense within the same
st->bucket.

These two variables are an optimization for the common no-lseek case.
When resuming the seq_file iteration (i.e. seq_start()),
tcp_seek_last_pos() tries to continue from the st->offset
at bucket st->bucket.

However, it is possible that the bucket pointed by st->bucket
has changed and st->offset may end up skipping the whole st->bucket
without finding a sk.  In this case, tcp_seek_last_pos() currently
continues to satisfy the offset condition in the next (and incorrect)
bucket.  Instead, regardless of the offset value, the first sk of the
next bucket should be returned.  Thus, "bucket == st->bucket" check is
added to tcp_seek_last_pos().

The chance of hitting this is small and the issue is a decade old,
so targeting for the next tree.

2bdd92210f spi: spi-pic32: Fix issue with uninitialized dma_slave_config
[ Upstream commit 976c1de1de ]

Depending on the DMA driver being used, the struct dma_slave_config may
need to be initialized to zero for the unused data.

For example, we have three DMA drivers using src_port_window_size and
dst_port_window_size. If these are left uninitialized, it can cause DMA
failures.

For spi-pic32, this is probably not currently an issue but is still good to
fix though.

7e990a8394 x86/reboot: Limit Dell Optiplex 990 quirk to early BIOS versions
commit a729691b54 upstream.

When this platform was relatively new in November 2011, with early BIOS
revisions, a reboot quirk was added in commit 6be30bb7d7 ("x86/reboot:
Blacklist Dell OptiPlex 990 known to require PCI reboot")

However, this quirk (and several others) are open-ended to all BIOS
versions and left no automatic expiry if/when the system BIOS fixed the
issue, meaning that nobody is likely to come along and re-test.

What is really problematic with using PCI reboot as this quirk does, is
that it causes this platform to do a full power down, wait one second,
and then power back on.  This is less than ideal if one is using it for
boot testing and/or bisecting kernels when legacy rotating hard disks
are installed.

It was only by chance that the quirk was noticed in dmesg - and when
disabled it turned out that it wasn't required anymore (BIOS A24), and a
default reboot would work fine without the "harshness" of power cycling the
machine (and disks) down and up like the PCI reboot does.

Doing a bit more research, it seems that the "newest" BIOS for which the
issue was reported[1] was version A06, however Dell[2] seemed to suggest
only up to and including version A05, with the A06 having a large number of
fixes[3] listed.

As is typical with a new platform, the initial BIOS updates come frequently
and then taper off (and in this case, with a revival for CPU CVEs); a
search for O990-A<ver>.exe reveals the following dates:

        A02     16 Mar 2011
        A03     11 May 2011
        A06     14 Sep 2011
        A07     24 Oct 2011
        A10     08 Dec 2011
        A14     06 Sep 2012
        A16     15 Oct 2012
        A18     30 Sep 2013
        A19     23 Sep 2015
        A20     02 Jun 2017
        A23     07 Mar 2018
        A24     21 Aug 2018

While it's overkill to flash and test each of the above, it would seem
likely that the issue was contained within A0x BIOS versions, given the
dates above and the dates of issue reports[4] from distros.  So rather than
just throw out the quirk entirely, limit the scope to just those early BIOS
versions, in case people are still running systems from 2011 with the
original as-shipped early A0x BIOS versions.

d6cfa43471 Revert "btrfs: compression: don't try to compress if we don't have enough pages"
commit 4e9655763b upstream.

This reverts commit f216562731.

[BUG]
It's no longer possible to create compressed inline extent after commit
f216562731 ("btrfs: compression: don't try to compress if we don't
have enough pages").

[CAUSE]
For compression code, there are several possible reasons we have a range
that needs to be compressed while it's no more than one page.

- Compressed inline write
  The data is always smaller than one sector and the test lacks the
  condition to properly recognize a non-inline extent.

- Compressed subpage write
  For the incoming subpage compressed write support, we require page
  alignment of the delalloc range.
  And for 64K page size, we can compress just one page into smaller
  sectors.

For those reasons, the requirement for the data to be more than one page
is not correct, and is already causing regression for compressed inline
data writeback.  The idea of skipping one page to avoid wasting CPU time
could be revisited in the future.

[FIX]
Fix it by reverting the offending commit.

cfbd6896ad mm/page_alloc: speed up the iteration of max_order
commit 7ad69832f3 upstream.

When we free a page whose order is very close to MAX_ORDER and greater
than pageblock_order, it wastes some CPU cycles to increase max_order to
MAX_ORDER one by one and check the pageblock migratetype of that page
repeatedly especially when MAX_ORDER is much larger than pageblock_order.

We also should not be checking migratetype of buddy when "order ==
MAX_ORDER - 1" as the buddy pfn may be invalid, so adjust the condition.
With the new check, we don't need the max_order check anymore, so we
replace it.

Also adjust max_order initialization so that it's lower by one than
previously, which makes the code hopefully more clear.

38614bd2cb ipv4/icmp: l3mdev: Perform icmp error route lookup on source device routing table (v2)
commit e1e84eb58e upstream.

As per RFC792, ICMP errors should be sent to the source host.

However, in configurations with Virtual Routing and Forwarding tables,
looking up which routing table to use is currently done by using the
destination net_device.

commit 9d1a6c4ea4 ("net: icmp_route_lookup should use rt dev to
determine L3 domain") changes the interface passed to
l3mdev_master_ifindex() and inet_addr_type_dev_table() from skb_in->dev
to skb_dst(skb_in)->dev. This effectively uses the destination device
rather than the source device for choosing which routing table should be
used to lookup where to send the ICMP error.

Therefore, if the source and destination interfaces are within separate
VRFs, or one in the global routing table and the other in a VRF, looking
up the source host in the destination interface's routing table will
fail if the destination interface's routing table contains no route to
the source host.

One observable effect of this issue is that traceroute does not work in
the following cases:

- Route leaking between global routing table and VRF
- Route leaking between VRFs

Preferably use the source device routing table when sending ICMP error
messages. If no source device is set, fall-back on the destination
device routing table. Else, use the main routing table (index 0).

[ It has been pointed out that a similar issue may exist with ICMP
  errors triggered when forwarding between network namespaces. It would
  be worthwhile to investigate, but is outside of the scope of this
  investigation. ]

[ It has also been pointed out that a similar issue exists with
  unreachable / fragmentation needed messages, which can be triggered by
  changing the MTU of eth1 in r1 to 1400 and running:

  ip netns exec h1 ping -s 1450 -Mdo -c1 172.16.2.2

  Some investigation points to raw_icmp_error() and raw_err() as being
  involved in this last scenario. The focus of this patch is TTL expired
  ICMP messages, which go through icmp_route_lookup.
  Investigation of failure modes related to raw_icmp_error() is beyond
  this investigation's scope. ]

6317fc0982 gfs2: Don't clear SGID when inheriting ACLs
commit 914cea93dd upstream.

When new directory 'DIR1' is created in a directory 'DIR0' with SGID bit
set, DIR1 is expected to have SGID bit set (and owning group equal to
the owning group of 'DIR0'). However when 'DIR0' also has some default
ACLs that 'DIR1' inherits, setting these ACLs will result in SGID bit on
'DIR1' to get cleared if user is not member of the owning group.

Fix the problem by moving posix_acl_update_mode() out of
__gfs2_set_acl() into gfs2_set_acl(). That way the function will not be
called when inheriting ACLs which is what we want as it prevents SGID
bit clearing and the mode has been properly set by posix_acl_create()
anyway.

commit c843455975 upstream.

We currently rely on runtime PM to enable dedicated wakeirq for suspend.
This assumption fails in the following two cases:

1. If the consumer driver does not have runtime PM implemented, the
   dedicated wakeirq never gets enabled for suspend

2. If the consumer driver has runtime PM implemented, but does not idle
   in suspend

Let's fix the issue by always enabling the dedicated wakeirq during
suspend.

To avoid having to do any additional operations during the main TX path
operations, track pending key cache entries in a new bitmap and check
whether any pending entries can be deleted before every new key
add/remove operation. Also clear any remaining entries when stopping the

752280ad78 ath9k: Clear key cache explicitly on disabling hardware
commit 73488cb2fa upstream.

Now that ath/key.c may not be explicitly clearing keys from the key
cache, clear all key cache entries when disabling hardware to make sure
no keys are left behind beyond this point.

6f068f6fed ath: Use safer key clearing with key cache entries
commit 56c5485c9e upstream.

It is possible for there to be pending frames in TXQs with a reference
to the key cache entry that is being deleted. If such a key cache entry
is cleared, those pending frame in TXQ might get transmitted without
proper encryption. It is safer to leave the previously used key into the
key cache in such cases. Instead, only clear the MAC address to prevent
RX processing from using this key cache entry.

This is needed in particularly in AP mode where the TXQs cannot be
flushed on station disconnection. This change alone may not be able to
address all cases where the key cache entry might get reused for other
purposes immediately (the key cache entry should be released for reuse
only once the TXQs do not have any remaining references to them), but
this makes it less likely to get unprotected frames and the more
complete changes may end up being significantly more complex.

4107588bdf ALSA: pcm: fix divide error in snd_pcm_lib_ioctl
commit f3eef46f05 upstream.

Syzkaller reported a divide error in snd_pcm_lib_ioctl. fifo_size
is of type snd_pcm_uframes_t(unsigned long). If frame_size
is 0x100000000, the error occurs.

369a030129 ARM: 8918/2: only build return_address() if needed
commit fb033c95c9 upstream.

The system currently warns if the config conditions for
building return_address in arch/arm/kernel/return_address.c
are not met, leaving just an EXPORT_SYMBOL_GPL(return_address)
of a function defined to be 'static linline'.
This is a result of aeea3592a1 ("ARM: 8158/1: LLVMLinux: use static inline in ARM ftrace.h").

Since we're not going to build anything other than an exported
symbol for something that is already being defined to be an
inline-able return of NULL, just avoid building the code to
remove the following warning:
