ioctl(SIOCINQ) calls unix_inq_len() that checks sk->sk_state first
and returns -EINVAL if it's TCP_LISTEN.
Then, for SOCK_STREAM sockets, unix_inq_len() returns the number of
bytes in recvq.
However, unix_inq_len() does not hold unix_state_lock(), and the
concurrent listen() might change the state after checking sk->sk_state.
If the race occurs, 0 is returned for the listener, instead of -EINVAL,
because the length of skb with embryo is 0.
We could hold unix_state_lock() in unix_inq_len(), but it's overkill
given the result is true for pre-listen() TCP_CLOSE state.
So, let's use READ_ONCE() for sk->sk_state in unix_inq_len().

When a SOCK_DGRAM socket connect()s to another socket, the both sockets'
sk->sk_state are changed to TCP_ESTABLISHED so that we can register them
to BPF SOCKMAP.
When the socket disconnects from the peer by connect(AF_UNSPEC), the state
is set back to TCP_CLOSE.
Then, the peer's state is also set to TCP_CLOSE, but the update is done
locklessly and unconditionally.
Let's say socket A connect()ed to B, B connect()ed to C, and A disconnects
from B.
After the first two connect()s, all three sockets' sk->sk_state are
TCP_ESTABLISHED:
$ ss -xa
Netid State Recv-Q Send-Q Local Address:Port Peer Address:PortProcess
u_dgr ESTAB 0 0 @A 641 * 642
u_dgr ESTAB 0 0 @B 642 * 643
u_dgr ESTAB 0 0 @C 643 * 0
And after the disconnect, B's state is TCP_CLOSE even though it's still
connected to C and C's state is TCP_ESTABLISHED.
$ ss -xa
Netid State Recv-Q Send-Q Local Address:Port Peer Address:PortProcess
u_dgr UNCONN 0 0 @A 641 * 0
u_dgr UNCONN 0 0 @B 642 * 643
u_dgr ESTAB 0 0 @C 643 * 0
In this case, we cannot register B to SOCKMAP.
So, when a socket disconnects from the peer, we should not set TCP_CLOSE to
the peer if the peer is connected to yet another socket, and this must be
done under unix_state_lock().
Note that we use WRITE_ONCE() for sk->sk_state as there are many lockless
readers. These data-races will be fixed in the following patches.

====================
Intel Wired LAN Driver Updates 2024-05-29 (ice, igc)
This series includes fixes for the ice driver as well as a fix for the igc
driver.
Jacob fixes two issues in the ice driver with reading the NVM for providing
firmware data via devlink info. First, fix an off-by-one error when reading
the Preserved Fields Area, resolving an infinite loop triggered on some
NVMs which lack certain data in the NVM. Second, fix the reading of the NVM
Shadow RAM on newer E830 and E825-C devices which have a variable sized CSS
header rather than assuming this header is always the same fixed size as in
the E810 devices.
Larysa fixes three issues with the ice driver XDP logic that could occur if
the number of queues is changed after enabling an XDP program. First, the
af_xdp_zc_qps bitmap is removed and replaced by simpler logic to track
whether queues are in zero-copy mode. Second, the reset and .ndo_bpf flows
are distinguished to avoid potential races with a PF reset occuring
simultaneously to .ndo_bpf callback from userspace. Third, the logic for
mapping XDP queues to vectors is fixed so that XDP state is restored for
XDP queues after a reconfiguration.
Sasha fixes reporting of Energy Efficient Ethernet support via ethtool in
the igc driver.

Commit 6624e780a577 ("ice: split ice_vsi_setup into smaller functions")
has placed ice_vsi_free_q_vectors() after ice_destroy_xdp_rings() in
the rebuild process. The behaviour of the XDP rings config functions is
context-dependent, so the change of order has led to
ice_destroy_xdp_rings() doing additional work and removing XDP prog, when
it was supposed to be preserved.
Also, dependency on the PF state reset flags creates an additional,
fortunately less common problem:
* PFR is requested e.g. by tx_timeout handler
* .ndo_bpf() is asked to delete the program, calls ice_destroy_xdp_rings(),
but reset flag is set, so rings are destroyed without deleting the
program
* ice_vsi_rebuild tries to delete non-existent XDP rings, because the
program is still on the VSI
* system crashes
With a similar race, when requested to attach a program,
ice_prepare_xdp_rings() can actually skip setting the program in the VSI
and nevertheless report success.
Instead of reverting to the old order of function calls, add an enum
argument to both ice_prepare_xdp_rings() and ice_destroy_xdp_rings() in
order to distinguish between calls from rebuild and .ndo_bpf().

Referenced commit has introduced a bitmap to distinguish between ZC and
copy-mode AF_XDP queues, because xsk_get_pool_from_qid() does not do this
for us.
The bitmap would be especially useful when restoring previous state after
rebuild, if only it was not reallocated in the process. This leads to e.g.
xdpsock dying after changing number of queues.
Instead of preserving the bitmap during the rebuild, remove it completely
and distinguish between ZC and copy-mode queues based on the presence of
a device associated with the pool.

The ice driver reads data from the Shadow RAM portion of the NVM during
initialization, including data used to identify the NVM image and device,
such as the ETRACK ID used to populate devlink dev info fw.bundle.
Currently it is using a fixed offset defined by ICE_CSS_HEADER_LENGTH to
compute the appropriate offset. This worked fine for E810 and E822 devices
which both have CSS header length of 330 words.
Other devices, including both E825-C and E830 devices have different sizes
for their CSS header. The use of a hard coded value results in the driver
reading from the wrong block in the NVM when attempting to access the
Shadow RAM copy. This results in the driver reporting the fw.bundle as 0x0
in both the devlink dev info and ethtool -i output.
The first E830 support was introduced by commit ba20ecb1d1bb ("ice: Hook up
4 E830 devices by adding their IDs") and the first E825-C support was
introducted by commit f64e18944233 ("ice: introduce new E825C devices
family")
The NVM actually contains the CSS header length embedded in it. Remove the
hard coded value and replace it with logic to read the length from the NVM
directly. This is more resilient against all existing and future hardware,
vs looking up the expected values from a table. It ensures the driver will
read from the appropriate place when determining the ETRACK ID value used
for populating the fw.bundle_id and for reporting in ethtool -i.
The CSS header length for both the active and inactive flash bank is stored
in the ice_bank_info structure to avoid unnecessary duplicate work when
accessing multiple words of the Shadow RAM. Both banks are read in the
unlikely event that the header length is different for the NVM in the
inactive bank, rather than being different only by the overall device
family.

The ice_get_pfa_module_tlv() function iterates over the Type-Length-Value
structures in the Preserved Fields Area (PFA) of the NVM. This is used by
the driver to access data such as the Part Board Assembly identifier.
The function uses simple logic to iterate over the PFA. First, the pointer
to the PFA in the NVM is read. Then the total length of the PFA is read
from the first word.
A pointer to the first TLV is initialized, and a simple loop iterates over
each TLV. The pointer is moved forward through the NVM until it exceeds the
PFA area.
The logic seems sound, but it is missing a key detail. The Preserved
Fields Area length includes one additional final word. This is documented
in the device data sheet as a dummy word which contains 0xFFFF. All NVMs
have this extra word.
If the driver tries to scan for a TLV that is not in the PFA, it will read
past the size of the PFA. It reads and interprets the last dummy word of
the PFA as a TLV with type 0xFFFF. It then reads the word following the PFA
as a length.
The PFA resides within the Shadow RAM portion of the NVM, which is
relatively small. All of its offsets are within a 16-bit size. The PFA
pointer and TLV pointer are stored by the driver as 16-bit values.
In almost all cases, the word following the PFA will be such that
interpreting it as a length will result in 16-bit arithmetic overflow. Once
overflowed, the new next_tlv value is now below the maximum offset of the
PFA. Thus, the driver will continue to iterate the data as TLVs. In the
worst case, the driver hits on a sequence of reads which loop back to
reading the same offsets in an endless loop.
To fix this, we need to correct the loop iteration check to account for
this extra word at the end of the PFA. This alone is sufficient to resolve
the known cases of this issue in the field. However, it is plausible that
an NVM could be misconfigured or have corrupt data which results in the
same kind of overflow. Protect against this by using check_add_overflow
when calculating both the maximum offset of the TLVs, and when calculating
the next_tlv offset at the end of each loop iteration. This ensures that
the driver will not get stuck in an infinite loop when scanning the PFA.

In case pci channel becomes offline the driver should not wait for PCI
reads during health dump and recovery flow. The driver has timeout for
each of these loops trying to read PCI, so it would fail anyway.
However, in case of recovery waiting till timeout may cause the pci
error_detected() callback fail to meet pci_dpc_recovered() wait timeout.

The mainline MTK ethernet driver suffers long time from rarly but
annoying tx queue timeouts. We think that this is caused by fixed
dma sizes hardcoded for all SoCs.
We suspect this problem arises from a low level of free TX DMADs,
the TX Ring alomost full.
The transmit timeout is caused by the Tx queue not waking up. The
Tx queue stops when the free counter is less than ring->thres, and
it will wake up once the free counter is greater than ring->thres.
If the CPU is too late to wake up the Tx queues, it may cause a
transmit timeout.
Therefore, we increased the TX and RX DMADs to improve this error
situation.
Use the dma-size implementation from SDK in a per SoC manner. In
difference to SDK we have no RSS feature yet, so all RX/TX sizes
should be raised from 512 to 2048 byte except fqdma on mt7988 to
avoid the tx timeout issue.

Jaroslav reports Dell's OMSA Systems Management Data Engine
expects NLM_DONE in a separate recvmsg(), both for rtnl_dump_ifinfo()
and inet_dump_ifaddr(). We already added a similar fix previously in
commit 460b0d33cf10 ("inet: bring NLM_DONE out to a separate recv() again")
Instead of modifying all the dump handlers, and making them look
different than modern for_each_netdev_dump()-based dump handlers -
put the workaround in rtnetlink code. This will also help us move
the custom rtnl-locking from af_netlink in the future (in net-next).
Note that this change is not touching rtnl_dump_all(). rtnl_dump_all()
is different kettle of fish and a potential problem. We now mix families
in a single recvmsg(), but NLM_DONE is not coalesced.
Tested:

Like previous patch does in TCP, we need to adhere to RFC 1213:
"tcpCurrEstab OBJECT-TYPE
...
The number of TCP connections for which the current state
is either ESTABLISHED or CLOSE- WAIT."
So let's consider CLOSE-WAIT sockets.
The logic of counting
When we increment the counter?
a) Only if we change the state to ESTABLISHED.
When we decrement the counter?
a) if the socket leaves ESTABLISHED and will never go into CLOSE-WAIT,
say, on the client side, changing from ESTABLISHED to FIN-WAIT-1.
b) if the socket leaves CLOSE-WAIT, say, on the server side, changing
from CLOSE-WAIT to LAST-ACK.

According to RFC 1213, we should also take CLOSE-WAIT sockets into
consideration:
"tcpCurrEstab OBJECT-TYPE
...
The number of TCP connections for which the current state
is either ESTABLISHED or CLOSE- WAIT."
After this, CurrEstab counter will display the total number of
ESTABLISHED and CLOSE-WAIT sockets.
The logic of counting
When we increment the counter?
a) if we change the state to ESTABLISHED.
b) if we change the state from SYN-RECEIVED to CLOSE-WAIT.
When we decrement the counter?
a) if the socket leaves ESTABLISHED and will never go into CLOSE-WAIT,
say, on the client side, changing from ESTABLISHED to FIN-WAIT-1.
b) if the socket leaves CLOSE-WAIT, say, on the server side, changing
from CLOSE-WAIT to LAST-ACK.
Please note: there are two chances that old state of socket can be changed
to CLOSE-WAIT in tcp_fin(). One is SYN-RECV, the other is ESTABLISHED.
So we have to take care of the former case.

Drop the second snapshot of mmu_invalidate_seq in kvm_faultin_pfn().
Before checking the mismatch of private vs. shared, mmu_invalidate_seq is
saved to fault->mmu_seq, which can be used to detect an invalidation
related to the gfn occurred, i.e. KVM will not install a mapping in page
table if fault->mmu_seq != mmu_invalidate_seq.
Currently there is a second snapshot of mmu_invalidate_seq, which may not
be same as the first snapshot in kvm_faultin_pfn(), i.e. the gfn attribute
may be changed between the two snapshots, but the gfn may be mapped in
page table without hindrance. Therefore, drop the second snapshot as it
has no obvious benefits.

Commit f58f45c1e5b9 ("vxlan: drop packets from invalid src-address")
has recently been added to vxlan mainly in the context of source
address snooping/learning so that when it is enabled, an entry in the
FDB is not being created for an invalid address for the corresponding
tunnel endpoint.
Before commit f58f45c1e5b9 vxlan was similarly behaving as geneve in
that it passed through whichever macs were set in the L2 header. It
turns out that this change in behavior breaks setups, for example,
Cilium with netkit in L3 mode for Pods as well as tunnel mode has been
passing before the change in f58f45c1e5b9 for both vxlan and geneve.
After mentioned change it is only passing for geneve as in case of
vxlan packets are dropped due to vxlan_set_mac() returning false as
source and destination macs are zero which for E/W traffic via tunnel
is totally fine.
Fix it by only opting into the is_valid_ether_addr() check in
vxlan_set_mac() when in fact source address snooping/learning is
actually enabled in vxlan. This is done by moving the check into
vxlan_snoop(). With this change, the Cilium connectivity test suite
passes again for both tunnel flavors.

KSZ8061 needs to write to a MMD register at driver initialization to fix
an errata. This worked in 5.0 kernel but not in newer kernels. The
issue is the main phylib code no longer resets PHY at the very beginning.
Calling phy resuming code later will reset the chip if it is already
powered down at the beginning. This wipes out the MMD register write.
Solution is to implement a phy resume function for KSZ8061 to take care
of this problem.

When copying smc settings to clcsock, avoid setting clcsock's sk_sndbuf
to sysctl_tcp_wmem[1], since this may overwrite the value set by
tcp_sndbuf_expand() in TCP connection establishment.
And the other setting sk_{snd|rcv}buf to sysctl value in
smc_adjust_sock_bufsizes() can also be omitted since the initialization
of smc sock and clcsock has set sk_{snd|rcv}buf to smc.sysctl_{w|r}mem
or ipv4_sysctl_tcp_{w|r}mem[1].
