mm: lock_vma_under_rcu() must check vma->anon_vma under vma lock
lock_vma_under_rcu() tries to guarantee that __anon_vma_prepare() can't
be called in the VMA-locked page fault path by ensuring that
vma->anon_vma is set.
However, this check happens before the VMA is locked, which means a
concurrent move_vma() can concurrently call unlink_anon_vmas(), which
disassociates the VMA's anon_vma.
This means we can get UAF in the following scenario:

This is a security bug if you can hit it, although an attacker would
have to win two races at once where the first race window is only a few
instructions wide.

Arseniy Krasnov says:
====================
virtio/vsock: some updates for MSG_PEEK flag
This patchset does several things around MSG_PEEK flag support. In
general words it reworks MSG_PEEK test and adds support for this flag
in SOCK_SEQPACKET logic. Here is per-patch description:
1) This is cosmetic change for SOCK_STREAM implementation of MSG_PEEK:
1) I think there is no need of "safe" mode walk here as there is no
"unlink" of skbs inside loop (it is MSG_PEEK mode - we don't change
queue).
2) Nested while loop is removed: in case of MSG_PEEK we just walk
over skbs and copy data from each one. I guess this nested loop
even didn't behave as loop - it always executed just for single
iteration.
2) This adds MSG_PEEK support for SOCK_SEQPACKET. It could be implemented
be reworking MSG_PEEK callback for SOCK_STREAM to support SOCK_SEQPACKET
also, but I think it will be more simple and clear from potential
bugs to implemented it as separate function thus not mixing logics
for both types of socket. So I've added it as dedicated function.
3) This is reworked MSG_PEEK test for SOCK_STREAM. Previous version just
sent single byte, then tried to read it with MSG_PEEK flag, then read
it in normal way. New version is more complex: now sender uses buffer
instead of single byte and this buffer is initialized with random
values. Receiver tests several things:
1) Read empty socket with MSG_PEEK flag.
2) Read part of buffer with MSG_PEEK flag.
3) Read whole buffer with MSG_PEEK flag, then checks that it is same
as buffer from 2) (limited by size of buffer from 2) of course).
4) Read whole buffer without any flags, then checks that it is same
as buffer from 3).
4) This is MSG_PEEK test for SOCK_SEQPACKET. It works in the same way
as for SOCK_STREAM, except it also checks combination of MSG_TRUNC
and MSG_PEEK.

====================
net: ethernet: mtk_eth_soc: add basic support for MT7988 SoC
The MediaTek MT7988 SoC introduces a new version (3) of the NETSYS
block and comes with three instead of two MACs.
The first MAC can be internally connected to a built-in Gigabit
Ethernet switch with four 1000M/100M/10M twisted pair user ports.
The second MAC can be internally connected to a built-in 2500Base-T
Ethernet PHY.
There are two SerDes units which can be operated in USXGMII, 10GBase-(K)R,
5GBase-R, 2500Base-X, 1000Base-X or SGMII interface mode.
This series adds initial support for NETSYS v3 and the first MAC of the
MT7988 SoC connecting the built-in DSA switch.
The switch is supported since commit
110c18bfed414 ("net: dsa: mt7530:
introduce driver for MT7988 built-in switch").
Basic support for the 1000M/100M/10M built-in PHYs connected to the
switch ports is present since commit ("
98c485eaf509b net: phy: add
driver for MediaTek SoC built-in GE PHYs").

mm: suppress mm fault logging if fatal signal already pending
Commit
eda0047296a1 ("mm: make the page fault mmap locking killable")
intentionally made it much easier to trigger the "page fault fails
because a fatal signal is pending" situation, by having the mmap locking
fail early in that case.
We have long aborted page faults in other fatal cases when the actual IO
for a page is interrupted by SIGKILL - which is particularly useful for
the traditional case of NFS hanging due to network issues, but local
filesystems could cause it too if you happened to get the SIGKILL while
waiting for a page to be faulted in (eg lock_folio_maybe_drop_mmap()).
So aborting the page fault wasn't a new condition - but it now triggers
earlier, before we even get to 'handle_mm_fault()'. And as a result the
error doesn't go through our 'fault_signal_pending()' logic, and doesn't
get filtered away there.
Normally you'd never even notice, because if a fatal signal is pending,
the new SIGSEGV we send ends up being ignored anyway.
But it turns out that there is one very noticeable exception: if you
enable 'show_unhandled_signals', the aborted page fault will be logged
in the kernel messages, and you'll get a scary line looking something
like this in your logs:
pverados[2183248]: segfault at
55e5a00f9ae0 ip
000055e5a00f9ae0 sp
00007ffc0720bea8 error 14 in perl[
55e5a00d4000+195000] likely on CPU 10 (core 4, socket 0)
which is rather misleading. It's not really a segfault at all, it's
just "the thread was killed before the page fault completed, so we
aborted the page fault".
Fix this by just making it clear that a pending fatal signal means that
any new signal coming in after that is implicitly handled. This will
avoid the misleading logging, since now the signal isn't 'unhandled' any
more.

The lazy gc on insert that should remove timed-out entries fails to release
the other half of the interval, if any.
Can be reproduced with tests/shell/testcases/sets/0044interval_overlap_0
in nftables.git and kmemleak enabled kernel.
Second bug is the use of rbe_prev vs. prev pointer.
If rbe_prev() returns NULL after at least one iteration, rbe_prev points
to element that is not an end interval, hence it should not be removed.
Lastly, check the genmask of the end interval if this is active in the
current generation.

btrfs: check for commit error at btrfs_attach_transaction_barrier()
btrfs_attach_transaction_barrier() is used to get a handle pointing to the
current running transaction if the transaction has not started its commit
yet (its state is < TRANS_STATE_COMMIT_START). If the transaction commit
has started, then we wait for the transaction to commit and finish before
returning - however we completely ignore if the transaction was aborted
due to some error during its commit, we simply return ERR_PT(-ENOENT),
which makes the caller assume everything is fine and no errors happened.
This could make an fsync return success (0) to user space when in fact we
had a transaction abort and the target inode changes were therefore not
persisted.
Fix this by checking for the return value from btrfs_wait_for_commit(),
and if it returned an error, return it back to the caller.

igc: Fix Kernel Panic during ndo_tx_timeout callback
The Xeon validation group has been carrying out some loaded tests
with various HW configurations, and they have seen some transmit
queue time out happening during the test. This will cause the
reset adapter function to be called by igc_tx_timeout().
Similar race conditions may arise when the interface is being brought
down and up in igc_reinit_locked(), an interrupt being generated, and
igc_clean_tx_irq() being called to complete the TX.
When the igc_tx_timeout() function is invoked, this patch will turn
off all TX ring HW queues during igc_down() process. TX ring HW queues
will be activated again during the igc_configure_tx_ring() process
when performing the igc_up() procedure later.
This patch also moved existing igc_disable_tx_ring_hw() to avoid using
forward declaration.

- When a FDB entry doesn't exist, aging was never actually set to the

Fix both problem by adding aging support to the function, calling the

net: dsa: qca8k: enable use_single_write for qca8xxx
The qca8xxx switch supports 2 way to write reg values, a slow way using
mdio and a fast way by sending specially crafted mgmt packet to
read/write reg.
The fast way can support up to 32 bytes of data as eth packet are used
to send/receive.
This correctly works for almost the entire regmap of the switch but with
the use of some kernel selftests for dsa drivers it was found a funny
and interesting hw defect/limitation.
For some specific reg, bulk write won't work and will result in writing
only part of the requested regs resulting in half data written. This was
especially hard to track and discover due to the total strangeness of
the problem and also by the specific regs where this occurs.
This occurs in the specific regs of the ATU table, where multiple entry
needs to be written to compose the entire entry.
It was discovered that with a bulk write of 12 bytes on
QCA8K_REG_ATU_DATA0 only QCA8K_REG_ATU_DATA0 and QCA8K_REG_ATU_DATA2
were written, but QCA8K_REG_ATU_DATA1 was always zero.
Tcpdump was used to make sure the specially crafted packet was correct
and this was confirmed.
The problem was hard to track as the lack of QCA8K_REG_ATU_DATA1
resulted in an entry somehow possible as the first bytes of the mac
address are set in QCA8K_REG_ATU_DATA0 and the entry type is set in
QCA8K_REG_ATU_DATA2.
Funlly enough writing QCA8K_REG_ATU_DATA1 results in the same problem
with QCA8K_REG_ATU_DATA2 empty and QCA8K_REG_ATU_DATA1 and
QCA8K_REG_ATU_FUNC correctly written.
A speculation on the problem might be that there are some kind of
indirection internally when accessing these regs and they can't be
accessed all together, due to the fact that it's really a table mapped
somewhere in the switch SRAM.
Even more funny is the fact that every other reg was tested with all
kind of combination and they are not affected by this problem. Read
operation was also tested and always worked so it's not affected by this
problem.
The problem is not present if we limit writing a single reg at times.
To handle this hardware defect, enable use_single_write so that bulk
api can correctly split the write in multiple different operation
effectively reverting to a non-bulk write.

====================
ice: switchdev bridge offload
Wojciech Drewek says:
Linux bridge provides ability to learn MAC addresses and vlans
detected on bridge's ports. As a result of this, FDB (forward data base)
entries are created and they can be offloaded to the HW. By adding
VF's port representors to the bridge together with the uplink netdev,
we can learn VF's and link partner's MAC addresses. This is achieved
by slow/exception-path, where packets that do not match any filters
(FDB entries in this case) are send to the bridge ports.
Driver keeps track of the netdevs added to the bridge
by listening for NETDEV_CHANGEUPPER event. We distinguish two types
of bridge ports: uplink port and VF's representor port. Linux
bridge always learns src MAC of the packet on rx path. With the
current slow-path implementation, it means that we will learn
VF's MAC on port repr (when the VF transmits the packet) and
link partner's MAC on uplink (when we receive it on uplink from LAN).
The driver is notified about learning of the MAC/VLAN by
SWITCHDEV_FDB_{ADD|DEL}_TO_DEVICE events. This is followed by creation
of the HW filter. The direction of the filter is based on port
type (uplink or VF repr). In case of the uplink, rule forwards
the packets to the LAN (matching on link partner's MAC). When the
notification is received on VF repr then the rule forwards the
packets to the associated VF (matching on VF's MAC).
This approach would not work on its own however. This is because if
one of the directions is offloaded, then the bridge would not be able
to learn the other one. If the egress rule is added (learned on uplink)
then the response from the VF will be sent directly to the LAN.
The packet will not got through slow-path, it would not be seen on
VF's port repr. Because of that, the bridge would not learn VF's MAC.
This is solved by introducing guard rule. It prevents forward rule from
working until the opposite direction is offloaded.
Aging is not fully supported yet, aging time is static for now. The
follow up submissions will introduce counters that will allow us to
keep track if the rule is actually being used or not.
A few fixes/changes are needed for this feature to work with ice driver.
These are introduced in first 5 patches.

net: stmmac: correct MAC propagation delay
The IEEE1588 Standard specifies that the timestamps of Packets must be
captured when the PTP message timestamp point (leading edge of first
octet after the start of frame delimiter) crosses the boundary between
the node and the network. As the MAC latches the timestamp at an
internal point, the captured timestamp must be corrected for the
additional path latency, as described in the publicly available
datasheet [1].
This patch only corrects for the MAC-Internal delay, which can be read
out from the MAC_Ingress_Timestamp_Latency register, since the Phy
framework currently does not support querying the Phy ingress and egress
latency. The Closs Domain Crossing Circuits errors as indicated in [1]
are already being accounted in the stmmac_get_tx_hwtstamp() function and
are not corrected here.
As the Latency varies for different link speeds and MII
modes of operation, the correction value needs to be updated on each
link state change.
As the delay also causes a phase shift in the timestamp counter compared
to the rest of the network, this correction will also reduce phase error
when generating PPS outputs from the timestamp counter.

net: ipa: only reset hashed tables when supported
Last year, the code that manages GSI channel transactions switched
from using spinlock-protected linked lists to using indexes into the
ring buffer used for a channel. Recently, Google reported seeing
transaction reference count underflows occasionally during shutdown.
Doug Anderson found a way to reproduce the issue reliably, and
bisected the issue to the commit that eliminated the linked lists
and the lock. The root cause was ultimately determined to be
related to unused transactions being committed as part of the modem
shutdown cleanup activity. Unused transactions are not normally
expected (except in error cases).
The modem uses some ranges of IPA-resident memory, and whenever it
shuts down we zero those ranges. In ipa_filter_reset_table() a
transaction is allocated to zero modem filter table entries. If
hashing is not supported, hashed table memory should not be zeroed.
But currently nothing prevents that, and the result is an unused
transaction. Something similar occurs when we zero routing table
entries for the modem.
By preventing any attempt to clear hashed tables when hashing is not
supported, the reference count underflow is avoided in this case.
Note that there likely remains an issue with properly freeing unused
transactions (if they occur due to errors). This patch addresses
only the underflows that Google originally reported.

af_packet: Fix warning of fortified memcpy() in packet_getname().
syzkaller found a warning in packet_getname() [0], where we try to

Some devices (ip6gre, vti6, ip6tnl) have 16 bytes address expressed
by struct in6_addr. Also, Infiniband has 32 bytes as MAX_ADDR_LEN.
The write seems to overflow, but actually not since we use struct
sockaddr_storage defined in __sys_getsockname() and its size is 128
(_K_SS_MAXSIZE) bytes. Thus, we have sufficient room after sll_addr[]
as __data[].
To avoid the warning, let's add a flex array member union-ed with
sll_addr.
Another option would be to use strncpy() and limit the copied length
to sizeof(sll_addr), but it will return the partial address and break
an application that passes sockaddr_storage to getsockname().

af_unix: Fix fortify_panic() in unix_bind_bsd().
syzkaller found a bug in unix_bind_bsd() [0]. We can reproduce it
by bind()ing a socket on a path with length 108.
108 is the size of sun_addr of struct sockaddr_un and is the maximum
valid length for the pathname socket. When calling bind(), we use
struct sockaddr_storage as the actual buffer size, so terminating
sun_addr[108] with null is legitimate as done in unix_mkname_bsd().
However, strlen(sunaddr) for such a case causes fortify_panic() if
CONFIG_FORTIFY_SOURCE=y. __fortify_strlen() has no idea about the
actual buffer size and see the string as unterminated.
Let's use strnlen() to allow sun_addr to be unterminated at 107.

s390/lcs: Remove FDDI option
The last s390 machine that supported FDDI was z900 ('7th generation',
released in 2000). The oldest machine generation currently supported by
the Linux kernel is MARCH_Z10 (released 2008). If there is still a usecase
for connecting a Linux on s390 instance to a LAN Channel Station (LCS), it
can only do so via Ethernet.
Randy Dunlap[1] found that LCS over FDDI has never worked, when FDDI
was compiled as module. Instead of fixing that, remove the FDDI option
from the lcs driver.
While at it, make the CONFIG_LCS description a bit more helpful.

However, it forgot to describe the nla_policy at macvlan_policy

platform/x86: msi-laptop: Fix rfkill out-of-sync on MSI Wind U100
Only the HW rfkill state is toggled on laptops with quirks->ec_read_only
(so far only MSI Wind U90/U100). There are, however, a few issues with
the implementation:
1. The initial HW state is always unblocked, regardless of the actual
state on boot, because msi_init_rfkill only sets the SW state,
regardless of ec_read_only.
2. The initial SW state corresponds to the actual state on boot, but it
can't be changed afterwards, because set_device_state returns
-EOPNOTSUPP. It confuses the userspace, making Wi-Fi and/or Bluetooth
unusable if it was blocked on boot, and breaking the airplane mode if
the rfkill was unblocked on boot.
Address the above issues by properly initializing the HW state on
ec_read_only laptops and by allowing the userspace to toggle the SW
state. Don't set the SW state ourselves and let the userspace fully
control it. Toggling the SW state is a no-op, however, it allows the
userspace to properly toggle the airplane mode. The actual SW radio
disablement is handled by the corresponding rtl818x_pci and btusb
drivers that have their own rfkills.

====================
Remove legacy phylink behaviour
This series removes the - as far as I can tell - unreachable code in
mtk_eth_soc that relies upon legacy phylink behaviour, and then removes
the support in phylink for this legacy behaviour.
Patch 1 removes the clocking configuration from mtk_eth_soc for non-
TRGMII, non-serdes based interface modes, and disables those interface
modes prior to phylink configuration.
Patch 2 removes the mac_pcs_get_state() method from mtk_eth_soc which
I believe is also not used - mtk_eth_soc appears not to be used with
SFPs (which would use a kind of in-band mode) nor does any DT appear
to specify in-band mode for any non-serdes based interface mode.
With both of those dealt with, the kernel is now free of any driver
relying on the phylink legacy mode. Therefore, patch 3 removes support
for this.
Finally, with the advent of a new driver being submitted today that
makes use of state->speed in the mac_config() path, patch 4 ensures that
any phylink_link_state member that should not be used in mac_config is
either cleared or set to an invalid value.

MT7623 GMAC0 attempts to configure the system clocking according to the

state->speed setting has never been reliable in the .mac_config
callback - there are cases where this is not the link speed,
particularly via ethtool paths, so this has always been unreliable (as
detailed in phylink's documentation.)
There is the additional issue that mtk_gmac0_rgmii_adjust() will only
be called if state->interface changes, which means it only configures
the system clocking on the very first .mac_config call, which will be
made when the network device is first brought up before any link is
established.
Essentially, this code is incredibly buggy, and probably never worked.
Moreover, checking the in-kernel DT files, it seems no platform makes
use of this code path.

octeontx2-af: Fix hash extraction enable configuration
As of today, hash extraction support is enabled for all the silicons.
Because of which we are facing initialization issues when the silicon
does not support hash extraction. During creation of the hardware
parsing table for IPv6 address, we need to consider if hash extraction
is enabled then extract only 32 bit, otherwise 128 bit needs to be
extracted. This patch fixes the issue and configures the hardware parser
based on the availability of the feature.

octeontx2-af: Install TC filter rules in hardware based on priority
As of today, hardware does not support installing tc filter
rules based on priority. This patch adds support to install
the hardware rules based on priority. The final hardware rules
will not be dependent on rule installation order, it will be strictly
priority based, same as software.

Merge branch 'fix-up-dev-flags-when-add-p2p-down-link'
Hangbin Liu says:
====================
Fix up dev flags when add P2P down link
When adding p2p interfaces to bond/team. The POINTOPOINT, NOARP flags are
not inherit to up devices. Which will trigger IPv6 DAD. Since there is
no ethernet MAC address for P2P devices. This will cause unexpected DAD
failures.

team: reset team's flags when down link is P2P device
When adding a point to point downlink to team device, we neglected to reset
the team's flags, which were still using flags like BROADCAST and
MULTICAST. Consequently, this would initiate ARP/DAD for P2P downlink
interfaces, such as when adding a GRE device to team device. Fix this by
remove multicast/broadcast flags and add p2p and noarp flags.
After removing the none ethernet interface and adding an ethernet interface
to team, we need to reset team interface flags. Unlike bonding interface,
team do not need restore IFF_MASTER, IFF_SLAVE flags.
