Jason A. Donenfeld says:
====================
wireguard fixes for 6.5-rc6
Just one patch this time, somewhat late in the cycle:
1) Fix an off-by-one calculation for the maximum node depth size in the
allowedips trie data structure, and also adjust the self-tests to hit
this case so it doesn't regress again in the future.

In the allowedips self-test, nodes are inserted into the tree, but it
generated an even amount of nodes, but for checking maximum node depth,
there is of course the root node, which makes the total number
necessarily odd. With two few nodes added, it never triggered the
maximum depth check like it should have. So, add 129 nodes instead of
128 nodes, and do so with a more straightforward scheme, starting with
all the bits set, and shifting over one each time. Then increase the
maximum depth to 129, and choose a better name for that variable to
make it clear that it represents depth as opposed to bits.

BUG_ON(!vlan_info) is triggered in unregister_vlan_dev() with
following testcase:
# ip netns add ns1
# ip netns exec ns1 ip link add bond0 type bond mode 0
# ip netns exec ns1 ip link add bond_slave_1 type veth peer veth2
# ip netns exec ns1 ip link set bond_slave_1 master bond0
# ip netns exec ns1 ip link add link bond_slave_1 name vlan10 type vlan id 10 protocol 802.1ad
# ip netns exec ns1 ip link add link bond0 name bond0_vlan10 type vlan id 10 protocol 802.1ad
# ip netns exec ns1 ip link set bond_slave_1 nomaster
# ip netns del ns1
The logical analysis of the problem is as follows:
1. create ETH_P_8021AD protocol vlan10 for bond_slave_1:
register_vlan_dev()
vlan_vid_add()
vlan_info_alloc()
__vlan_vid_add() // add [ETH_P_8021AD, 10] vid to bond_slave_1
2. create ETH_P_8021AD protocol bond0_vlan10 for bond0:
register_vlan_dev()
vlan_vid_add()
__vlan_vid_add()
vlan_add_rx_filter_info()
if (!vlan_hw_filter_capable(dev, proto)) // condition established because bond0 without NETIF_F_HW_VLAN_STAG_FILTER
return 0;
if (netif_device_present(dev))
return dev->netdev_ops->ndo_vlan_rx_add_vid(dev, proto, vid); // will be never called
// The slaves of bond0 will not refer to the [ETH_P_8021AD, 10] vid.
3. detach bond_slave_1 from bond0:
__bond_release_one()
vlan_vids_del_by_dev()
list_for_each_entry(vid_info, &vlan_info->vid_list, list)
vlan_vid_del(dev, vid_info->proto, vid_info->vid);
// bond_slave_1 [ETH_P_8021AD, 10] vid will be deleted.
// bond_slave_1->vlan_info will be assigned NULL.
4. delete vlan10 during delete ns1:
default_device_exit_batch()
dev->rtnl_link_ops->dellink() // unregister_vlan_dev() for vlan10
vlan_info = rtnl_dereference(real_dev->vlan_info); // real_dev of vlan10 is bond_slave_1
BUG_ON(!vlan_info); // bond_slave_1->vlan_info is NULL now, bug is triggered!!!
Add S-VLAN tag related features support to bond driver. So the bond driver
will always propagate the VLAN info to its slaves.

The flow rule can be splited, and the extra post_act rules are added
to post_act table. It's possible to trigger memleak when the rule
forwards packets from internal port and over tunnel, in the case that,
for example, CT 'new' state offload is allowed. As int_port object is
assigned to the flow attribute of post_act rule, and its refcnt is
incremented by mlx5e_tc_int_port_get(), but mlx5e_tc_int_port_put() is
not called, the refcnt is never decremented, then int_port is never
freed.
The kmemleak reports the following error:

The TPM RNG functionality is not necessary for entropy when the CPU
already supports the RDRAND instruction. The TPM RNG functionality
was previously disabled on a subset of AMD fTPM series, but reports
continue to show problems on some systems causing stutter root caused
to TPM RNG functionality.
Expand disabling TPM RNG use for all AMD fTPMs whether they have versions
that claim to have fixed or not. To accomplish this, move the detection
into part of the TPM CRB registration and add a flag indicating that

In commit 3666062b87ec ("cpufreq: amd-pstate: move to use bus_get_dev_root()")
the "amd_pstate" attributes where moved from a dedicated kobject to the
cpu root kobject.
While the dedicated kobject expects to contain kobj_attributes the root
kobject needs device_attributes.
As the changed arguments are not used by the callbacks it works most of
the time.
However CFI will detect this issue:

Starting with patch 2cb1e08985, gfs2 started using the new function
filemap_splice_read rather than the old (and subsequently deleted)
function generic_file_splice_read.
filemap_splice_read works by taking references to a number of folios in
the page cache and splicing those folios into a pipe. The folios are
then read from the pipe and the folio references are dropped. This can
take an arbitrary amount of time. We cannot allow that in gfs2 because
those folio references will pin the inode glock to the node and prevent
it from being demoted, which can lead to cluster-wide deadlocks.
Instead, use copy_splice_read.
(In addition, the old generic_file_splice_read called into ->read_iter,
which called gfs2_file_read_iter, which took the inode glock during the
operation. The new filemap_splice_read interface does not take the
inode glock anymore. This is fixable, but it still wouldn't prevent
cluster-wide deadlocks.)

Function gfs2_trans_add_meta() checks for the SDF_FROZEN flag to make
sure that no buffers are added to a transaction while the filesystem is
frozen. With the recent freeze/thaw rework, the SDF_FROZEN flag is
cleared after thaw_super() is called, which is sufficient for
serializing freeze/thaw.
However, other filesystem operations started after thaw_super() may now
be calling gfs2_trans_add_meta() before the SDF_FROZEN flag is cleared,
which will trigger the SDF_FROZEN check in gfs2_trans_add_meta(). Fix
that by checking the s_writers.frozen state instead.
In addition, make sure not to call gfs2_assert_withdraw() with the
sd_log_lock spin lock held. Check for a withdrawn filesystem before
checking for a frozen filesystem, and don't pin/add buffers to the
current transaction in case of a failure in either case.

Tao Liu reported a boot hang on an Intel Atom machine due to an unmapped
EFI config table. The reason being that the CC blob which contains the
CPUID page for AMD SNP guests is parsed for before even checking
whether the machine runs on AMD hardware.
Usually that's not a problem on !AMD hw - it simply won't find the CC
blob's GUID and return. However, if any parts of the config table
pointers array is not mapped, the kernel will #PF very early in the
decompressor stage without any opportunity to recover.
Therefore, do a superficial CPUID check before poking for the CC blob.
This will fix the current issue on real hardware. It would also work as
a guest on a non-lying hypervisor.
For the lying hypervisor, the check is done again, *after* parsing the
CC blob as the real CPUID page will be present then.
Clear the #VC handler in case SEV-{ES,SNP} hasn't been detected, as
a precaution.

On a laptop with hibernation set up but not actively used, and with
secure boot and lockdown enabled kernel, 6.5-rc1 gets stuck on boot with
the following repeated messages:
A start job is running for Resume from hibernation using device /dev/system/swap (24s / no limit)
lockdown_is_locked_down: 25311154 callbacks suppressed
Lockdown: systemd-hiberna: hibernation is restricted; see man kernel_lockdown.7
...
Checking the resume code leads to commit cc89c63e2fe3 ("PM: hibernate:
move finding the resume device out of software_resume") which
inadvertently changed the return value from resume_store() to 0 when
!hibernation_available(). This apparently translates to userspace
write() returning 0 as in number of bytes written, and userspace looping
indefinitely in the attempt to write the intended value.
Fix this by returning the full number of bytes that were to be written,
as that's what was done before the commit.

A couple of hardware registers need to be set to reflect which
interrupts have been allocated to the device. Each register is 32-bit
wide and can receive four 8-bit values. If we provide any other interrupt
number than four, the irq_num variable will never be 0 within the while
check and the while block will loop forever.
There is an easy way to prevent this: just break the for loop
when we reach "irq_num == 0", which anyway means all interrupts have
been processed.

Then, this number of item is stored in 'mcf_edma->n_chans'.
A few lines later, if 'mcf_edma->n_chans' is 0, then a default value of 64
is set.
This ends to no space allocated by devm_kzalloc() because chans was 0, but

Now that we removed ->iterate we don't need to check for either
->iterate or ->iterate_shared in file_needs_f_pos_lock(). Simply check
for ->iterate_shared instead. This will tell us whether we need to
unconditionally take the lock. Not just does it allow us to avoid
checking f_inode's mode it also actually clearly shows that we're
locking because of readdir.

All users now just use '->iterate_shared()', which only takes the
directory inode lock for reading.
Filesystems that never got convered to shared mode now instead use a
wrapper that drops the lock, re-takes it in write mode, calls the old
function, and then downgrades the lock back to read mode.
This way the VFS layer and other callers no longer need to care about
filesystems that never got converted to the modern era.
The filesystems that use the new wrapper are ceph, coda, exfat, jfs,
ntfs, ocfs2, overlayfs, and vboxsf.
Honestly, several of them look like they really could just iterate their
directories in shared mode and skip the wrapper entirely, but the point
of this change is to not change semantics or fix filesystems that
haven't been fixed in the last 7+ years, but to finally get rid of the
dual iterators.

I'm looking at the directory handling due to the discussion about f_pos
locking (see commit 797964253d35: "file: reinstate f_pos locking
optimization for regular files"), and wanting to clean that up.
And one source of ugliness is how we were supposed to move filesystems
over to the '->iterate_shared()' function that only takes the inode lock
for reading many many years ago, but several filesystems still use the
bad old '->iterate()' that takes the inode lock for exclusive access.
See commit 6192269444eb ("introduce a parallel variant of ->iterate()")
that also added some documentation stating
Old method is only used if the new one is absent; eventually it will
be removed. Switch while you still can; the old one won't stay.
and that was back in April 2016. Here we are, many years later, and the
old version is still clearly sadly alive and well.
Now, some of those old style iterators are probably just because the
filesystem may end up having per-inode mutable data that it uses for
iterating a directory, but at least one case is just a mistake.
Al switched over most filesystems to use '->iterate_shared()' back when
it was introduced. In particular, the /proc filesystem was converted as
one of the first ones in commit f50752eaa0b0 ("switch all procfs
directories ->iterate_shared()").
But then later one new user of '->iterate()' was then re-introduced by
commit 6d9c939dbe4d ("procfs: add smack subdir to attrs").
And that's clearly not what we wanted, since that new case just uses the
same 'proc_pident_readdir()' and 'proc_pident_lookup()' helper functions
that other /proc pident directories use, and they are most definitely
safe to use with the inode lock held shared.
So just fix it.
This still leaves a fair number of oddball filesystems using the
old-style directory iterator (ceph, coda, exfat, jfs, ntfs, ocfs2,
overlayfs, and vboxsf), but at least we don't have any remaining in the
core filesystems.
I'm going to add a wrapper function that just drops the read-lock and
takes it as a write lock, so that we can clean up the core vfs layer and
make all the ugly 'this filesystem needs exclusive inode locking' be
just filesystem-internal warts.
I just didn't want to make that conversion when we still had a core user
left.

need to make space for this tag in the stream, the device will
generate and replace it with the actual calculated tag.
Long time ago the code would just re-reference the head frag
which mostly worked but was suboptimal because it prevented TCP
from combining the record into a single skb frag. I'm not sure
if it was correct as the first frag may be shorter than the tag.
The commit under fixes tried to replace that with using the page
frag and if the allocation failed rolling back the data, if record
was long enough. It achieves better fragment coalescing but is
also buggy.
We don't roll back the iterator, so unless we're at the end of
send we'll skip the data we designated as tag and start the
next record as if the rollback never happened.
There's also the possibility that the record was constructed
with MSG_MORE and the data came from a different syscall and
we already told the user space that we "got it".
Allocate a single dummy page and use it as fallback.
Found by code inspection, and proven by forcing allocation
failures.

There are multiple smb2_ea_info buffers in FILE_FULL_EA_INFORMATION request
from client. ksmbd find next smb2_ea_info using ->NextEntryOffset of
current smb2_ea_info. ksmbd need to validate buffer length Before
accessing the next ea. ksmbd should check buffer length using buf_len,
not next variable. next is the start offset of current ea that got from
previous ea.

In commit 2b9b8f3b68ed ("ksmbd: validate command payload size"), except
for SMB2_OPLOCK_BREAK_HE command, the request size of other commands
is not checked, it's not expected. Fix it by add check for request
size of other commands.
