There are sleep in atomic bug that could cause kernel panic during

GFP_KERNEL parameter is called in fw_dnld_timeout which is a timer
handler. The call trace is shown below:

The nlmsg_new with GFP_KERNEL parameter may sleep during memory
allocation process, and the timer handler is run as the result of
a "software interrupt" that should not call any other function
that could sleep.

This patch changes allocation mode of netlink message from GFP_KERNEL
to GFP_ATOMIC in order to prevent sleep in atomic bug. The GFP_ATOMIC
flag makes memory allocation operation could be used in atomic context.

Reading 100KB chunks from a big file (eg dd bs=100K) leads to poor
readahead behaviour.  Studying the traces in detail, I noticed two
problems.

The first is that we were setting the readahead flag on the folio which
contains the last byte read from the block.  This is wrong because we
will trigger readahead at the end of the read without waiting to see
if a subsequent read is going to use the pages we just read.  Instead,
we need to set the readahead flag on the first folio _after_ the one
which contains the last byte that we're reading.

The second is that we were looking for the index of the folio with the
readahead flag set to exactly match the start + size - async_size.
If we've rounded this, either down (as previously) or up (as now),
we'll think we hit a folio marked as readahead by a different read,
and try to read the wrong pages.  So round the expected index to the
order of the folio we hit.

It is unsafe to call folio_next() on a folio unless you hold a reference
on it that prevents it from being split or freed.  After returning
from the iterator, iomap calls folio_end_writeback() which may drop
the last reference to the page, or allow the page to be split.  If that
happens, the iterator will not advance far enough through the bio_vec,
leading to assertion failures like the BUG() in folio_end_writeback()
that checks we're not trying to end writeback on a page not currently
under writeback.  Other assertion failures were also seen, but they're
all explained by this one bug.

Fix the bug by remembering where the next folio starts before returning
from the iterator.  There are other ways of fixing this bug, but this
seems the simplest.

As discussed here with Ido Schimmel:
https://patchwork.kernel.org/project/netdevbpf/patch/20220224102908.5255-2-jianbol@nvidia.com/

the default conform-exceed action is "reclassify", for a reason we don't
really understand.

The point is that hardware can't offload that police action, so not
specifying "conform-exceed" was always wrong, even though the command
used to work in hardware (but not in software) until the kernel started
adding validation for it.

Fix the command used by the selftest by making the policer drop on
exceed, and pass the packet to the next action (goto) on conform.

====================
insufficient TCP source port randomness

In a not-yet published paper, Moshe Kol, Amit Klein, and Yossi Gilad
report being able to accurately identify a client by forcing it to emit
only 40 times more connections than the number of entries in the
table_perturb[] table, which is indexed by hashing the connection tuple.
The current 2^8 setting allows them to perform that attack with only 10k
connections, which is not hard to achieve in a few seconds.

Eric, Amit and I have been working on this for a few weeks now imagining,
testing and eliminating a number of approaches that Amit and his team were
still able to break or that were found to be too risky or too expensive,
and ended up with the simple improvements in this series that resists to
the attack, doesn't degrade the performance, and preserves a reliable port
selection algorithm to avoid connection failures, including the odd/even
port selection preference that allows bind() to always find a port quickly
even under strong connect() stress.

The approach relies on several factors:
  - resalting the hash secret that's used to choose the table_perturb[]
    entry every 10 seconds to eliminate slow attacks and force the
    attacker to forget everything that was learned after this delay.
    This already eliminates most of the problem because if a client
    stays silent for more than 10 seconds there's no link between the
    previous and the next patterns, and 10s isn't yet frequent enough
    to cause too frequent repetition of a same port that may induce a
    connection failure ;

  - adding small random increments to the source port. Previously, a
    random 0 or 1 was added every 16 ports. Now a random 0 to 7 is
    added after each port. This means that with the default 32768-60999
    range, a worst case rollover happens after 1764 connections, and
    an average of 3137. This doesn't stop statistical attacks but
    requires significantly more iterations of the same attack to
    confirm a guess.

  - increasing the table_perturb[] size from 2^8 to 2^16, which Amit
    says will require 2.6 million connections to be attacked with the
    changes above, making it pointless to get a fingerprint that will
    only last 10 seconds. Due to the size, the table was made dynamic.

  - a few minor improvements on the bits used from the hash, to eliminate
    some unfortunate correlations that may possibly have been exploited
    to design future attack models.

These changes were tested under the most extreme conditions, up to
1.1 million connections per second to one and a few targets, showing no
performance regression, and only 2 connection failures within 13 billion,
which is less than 2^-32 and perfectly within usual values.

The series is split into small reviewable changes and was already reviewed
by Amit and Eric.

In commit 190cc824 ("tcp: change source port randomizarion at
connect() time"), the table_perturb[] array was introduced and an
index was taken from the port_offset via hash_32(). But it turns
out that hash_32() performs a multiplication while the input here
comes from the output of SipHash in secure_seq, that is well
distributed enough to avoid the need for yet another hash.

Moshe Kol, Amit Klein, and Yossi Gilad reported being able to accurately
identify a client by forcing it to emit only 40 times more connections
than there are entries in the table_perturb[] table. The previous two
improvements consisting in resalting the secret every 10s and adding
randomness to each port selection only slightly improved the situation,
and the current value of 2^8 was too small as it's not very difficult
to make a client emit 10k connections in less than 10 seconds.

Thus we're increasing the perturb table from 2^8 to 2^16 so that the
same precision now requires 2.6M connections, which is more difficult in
this time frame and harder to hide as a background activity. The impact
is that the table now uses 256 kB instead of 1 kB, which could mostly
affect devices making frequent outgoing connections. However such
components usually target a small set of destinations (load balancers,
database clients, perf assessment tools), and in practice only a few
entries will be visited, like before.

A live test at 1 million connections per second showed no performance
difference from the previous value.

Here we're randomly adding between 0 and 7 random increments to the
selected source port in order to add some noise in the source port
selection that will make the next port less predictable.

With the default port range of 32768-60999 this means a worst case
reuse scenario of 14116/8=1764 connections between two consecutive
uses of the same port, with an average of 14116/4.5=3137. This code
was stressed at more than 800000 connections per second to a fixed
target with all connections closed by the client using RSTs (worst
condition) and only 2 connections failed among 13 billion, despite
the hash being reseeded every 10 seconds, indicating a perfectly

wireguard patches for 5.18-rc6

In working on some other problems, I wound up leaning on the WireGuard
CI more than usual and uncovered a few small issues with reliability.
These are fairly low key changes, since they don't impact kernel code
itself.

One change does stick out in particular, though, which is the "make
routing loop test non-fatal" commit. I'm not thrilled about doing this,
but currently [1] remains unsolved, and I'm still working on a real
solution to that (hopefully for 5.19 or 5.20 if I can come up with a

A faulty receiver might report an erroneous channel count. We
should guard against reading beyond AUDIO_CHANNELS_COUNT as
that would overflow the dpcd_pattern_period array.

While technically Xen dom0 is a virtual machine too, it does have
access to most of the hardware so it doesn't need to be considered a
"passthrough". Commit b818a5d3 ("drm/amdgpu/gmc: use PCI BARs for
APUs in passthrough") changed how FB is accessed based on passthrough
mode. This breaks amdgpu in Xen dom0 with message like this:

    [drm:dc_dmub_srv_wait_idle [amdgpu]] *ERROR* Error waiting for DMUB idle: status=3

While the reason for this failure is unclear, the passthrough mode is
not really necessary in Xen dom0 anyway. So, to unbreak booting affected
kernels, disable passthrough mode in this case.

Groups created by VFIO backends outside the core IOMMU API should never
be passed directly into the API itself, however they still expose their
standard sysfs attributes, so we can still stumble across them that way.
Take care to consider those cases before jumping into our normal
assumptions of a fully-initialised core API group.

Newer variants of the MMC controller support a 34-bit physical address
space by using word addresses instead of byte addresses. However, the
code truncates the DMA descriptor address to 32 bits before applying the
shift. This breaks DMA for descriptors allocated above the 32-bit limit.
