r8169: add handling DASH when DASH is disabled
For devices that support DASH, even DASH is disabled, there may still
exist a default firmware that will influence device behavior.
So driver needs to handle DASH for devices that support DASH, no
matter the DASH status is.
This patch also prepares for "fix network lost after resume on DASH
systems".

====================
Fix large frames in the Gemini ethernet driver
This is the result of a bug hunt for a problem with the
RTL8366RB DSA switch leading me wrong all over the place.
I am indebted to Vladimir Oltean who as usual pointed
out where the real problem was, many thanks!
Tryig to actually use big ("jumbo") frames on this
hardware uncovered the real bugs. Then I tested it on
the DSA switch and it indeed fixes the issue.
To make sure it also works fine with big frames on
non-DSA devices I also copied a large video file over
scp to a device with maximum frame size, the data
was transported in large TCP packets ending up in
0x7ff sized frames using software checksumming at
~2.0 MB/s.
If I set down the MTU to the standard 1500 bytes so
that hardware checksumming is used, the scp transfer
of the same file was slightly lower, ~1.8-1.9 MB/s.
Despite this not being the best test it shows that
we can now stress the hardware with large frames
and that software checksum works fine.

net: ethernet: cortina: Fix MTU max setting
The RX max frame size is over 10000 for the Gemini ethernet,
but the TX max frame size is actually just 2047 (0x7ff after
checking the datasheet). Reflect this in what we offer to Linux,
cap the MTU at the TX max frame minus ethernet headers.
We delete the code disabling the hardware checksum for large
MTUs as netdev->mtu can no longer be larger than
netdev->max_mtu meaning the if()-clause in gmac_fix_features()
is never true.

net: ethernet: cortina: Handle large frames
The Gemini ethernet controller provides hardware checksumming
for frames up to 1514 bytes including ethernet headers but not
FCS.
If we start sending bigger frames (after first bumping up the MTU
on both interfaces sending and receiving the frames), truncated
packets start to appear on the target such as in this tcpdump
resulting from ping -s 1474:
23:34:17.241983 14:d6:4d:a8:3c:4f (oui Unknown) > bc:ae:c5:6b:a8:3d (oui Unknown),
ethertype IPv4 (0x0800), length 1514: truncated-ip - 2 bytes missing!
(tos 0x0, ttl 64, id 32653, offset 0, flags [DF], proto ICMP (1), length 1502)
OpenWrt.lan > Fecusia: ICMP echo request, id 1672, seq 50, length 1482
If we bypass the hardware checksumming and provide a software
fallback, everything starts working fine up to the max TX MTU
of 2047 bytes, for example ping -s2000 192.168.1.2:
00:44:29.587598 bc:ae:c5:6b:a8:3d (oui Unknown) > 14:d6:4d:a8:3c:4f (oui Unknown),
ethertype IPv4 (0x0800), length 2042:
(tos 0x0, ttl 64, id 51828, offset 0, flags [none], proto ICMP (1), length 2028)
Fecusia > OpenWrt.lan: ICMP echo reply, id 1683, seq 4, length 2008
The bit enabling to bypass hardware checksum (or any of the
"TSS" bits) are undocumented in the hardware reference manual.
The entire hardware checksum unit appears undocumented. The
conclusion that we need to use the "bypass" bit was found by
trial-and-error.
Since no hardware checksum will happen, we slot in a software
checksum fallback.
Check for the condition where we need to compute checksum on the
skb with either hardware or software using == CHECKSUM_PARTIAL instead
of != CHECKSUM_NONE which is an incomplete check according to
<linux/skbuff.h>.
On the D-Link DIR-685 router this fixes a bug on the conduit
interface to the RTL8366RB DSA switch: as the switch needs to add
space for its tag it increases the MTU on the conduit interface
to 1504 and that means that when the router sends packages
of 1500 bytes these get an extra 4 bytes of DSA tag and the
transfer fails because of the erroneous hardware checksumming,
affecting such basic functionality as the LuCI web interface.

ptp: annotate data-race around q->head and q->tail
As I was working on a syzbot report, I found that KCSAN would
probably complain that reading q->head or q->tail without
barriers could lead to invalid results.
Add corresponding READ_ONCE() and WRITE_ONCE() to avoid
load-store tearing.

ppp: limit MRU to 64K
ppp_sync_ioctl allows setting device MRU, but does not sanity check
this input.
Limit to a sane upper bound of 64KB.
No implementation I could find generates larger than 64KB frames.
RFC 2823 mentions an upper bound of PPP over SDL of 64KB based on the
16-bit length field. Other protocols will be smaller, such as PPPoE
(9KB jumbo frame) and PPPoA (18190 maximum CPCS-SDU size, RFC 2364).
PPTP and L2TP encapsulate in IP.
Syzbot managed to trigger alloc warning in __alloc_pages:

net: mvneta: fix calls to page_pool_get_stats
Calling page_pool_get_stats in the mvneta driver without checks
leads to kernel crashes.
First the page pool is only available if the bm is not used.
The page pool is also not allocated when the port is stopped.
It can also be not allocated in case of errors.
The current implementation leads to the following crash calling
ethstats on a port that is down or when calling it at the wrong moment:

tipc_add_tlv() puts TLV descriptor and value onto `skb`. This size is
calculated with TLV_SPACE() macro. It adds the size of struct tlv_desc and
the length of TLV value passed as an argument, and aligns the result to a
multiple of TLV_ALIGNTO, i.e., a multiple of 4 bytes.
If the size of struct tlv_desc plus the length of TLV value is not aligned,
the current implementation leaves the remaining bytes uninitialized. This
is the cause of the above kernel-infoleak issue.
This patch resolves this issue by clearing data up to an aligned size.

net: hns3: fix VF wrong speed and duplex issue
If PF is down, firmware will returns 10 Mbit/s rate and half-duplex mode
when PF queries the port information from firmware.
After imp reset command is executed, PF status changes to down,
and PF will query link status and updates port information
from firmware in a periodic scheduled task.
However, there is a low probability that port information is updated
when PF is down, and then PF link status changes to up.
In this case, PF synchronizes incorrect rate and duplex mode to VF.
This patch fixes it by updating port information before
PF synchronizes the rate and duplex to the VF
when PF changes to up.

net: hns3: fix VF reset fail issue
Currently the reset process in hns3 and firmware watchdog init process is
asynchronous. We think firmware watchdog initialization is completed
before VF clear the interrupt source. However, firmware initialization
may not complete early. So VF will receive multiple reset interrupts
and fail to reset.
So we add delay before VF interrupt source and 5 ms delay
is enough to avoid second reset interrupt.

net: hns3: fix out-of-bounds access may occur when coalesce info is read via debugfs
The hns3 driver define an array of string to show the coalesce
info, but if the kernel adds a new mode or a new state,
out-of-bounds access may occur when coalesce info is read via
debugfs, this patch fix the problem.

net: hns3: fix incorrect capability bit display for copper port
Currently, the FEC capability bit is default set for device version V2.
It's incorrect for the copper port. Eventhough it doesn't make the nic
work abnormal, but the capability information display in debugfs may
confuse user. So clear it when driver get the port type inforamtion.

net: hns3: add barrier in vf mailbox reply process
In hclgevf_mbx_handler() and hclgevf_get_mbx_resp() functions,
there is a typical store-store and load-load scenario between
received_resp and additional_info. This patch adds barrier
to fix the problem.

net: hns3: fix add VLAN fail issue
The hclge_sync_vlan_filter is called in periodic task,
trying to remove VLAN from vlan_del_fail_bmap. It can
be concurrence with VLAN adding operation from user.
So once user failed to delete a VLAN id, and add it
again soon, it may be removed by the periodic task,
which may cause the software configuration being
inconsistent with hardware. So add mutex handling
to avoid this.

=====================================================
ppp_sync_input() checks the first 2 bytes of the data are PPP_ALLSTATIONS
and PPP_UI. However, if the data length is 1 and the first byte is
PPP_ALLSTATIONS, an access to an uninitialized value occurs when checking
PPP_UI. This patch resolves this issue by checking the data length.

ipvlan: add ipvlan_route_v6_outbound() helper
Inspired by syzbot reports using a stack of multiple ipvlan devices.
Reduce stack size needed in ipvlan_process_v6_outbound() by moving
the flowi6 struct used for the route lookup in an non inlined
helper. ipvlan_route_v6_outbound() needs 120 bytes on the stack,
immediately reclaimed.
Also make sure ipvlan_process_v4_outbound() is not inlined.
We might also have to lower MAX_NEST_DEV, because only syzbot uses
setups with more than four stacked devices.

net: set SOCK_RCU_FREE before inserting socket into hashtable

__inet_hash can race with lockless (rcu) readers on the other cpus:
__inet_hash
__sk_nulls_add_node_rcu
<- (bpf triggers here)
sock_set_flag(SOCK_RCU_FREE)
Let's move the SOCK_RCU_FREE part up a bit, before we are inserting
the socket into hashtables. Note, that the race is really harmless;
the bpf callers are handling this situation (where listener socket
doesn't have SOCK_RCU_FREE set) correctly, so the only
annoyance is a WARN_ONCE.
More details from Eric regarding SOCK_RCU_FREE timeline:

ptp: Fixes a null pointer dereference in ptp_ioctl
Syzkaller found a null pointer dereference in ptp_ioctl
originating from the lack of a null check for tsevq.

ptp: fix corrupted list in ptp_open
There is no lock protection when writing ptp->tsevqs in ptp_open() and
ptp_release(), which can cause data corruption, use spin lock to avoid this
issue.
Moreover, ptp_release() should not be used to release the queue in ptp_read(),
and it should be deleted altogether.

ptp: ptp_read should not release queue
Firstly, queue is not the memory allocated in ptp_read;
Secondly, other processes may block at ptp_read and wait for conditions to be

net/sched: act_ct: Always fill offloading tuple iifidx
Referenced commit doesn't always set iifidx when offloading the flow to hardware. Fix the following cases: - nf_conn_act_ct_ext_fill() is called before extension is created with nf_conn_act_ct_ext_add() in tcf_ct_act(). This can cause rule offload with unspecified iifidx when connection is offloaded after only single original-direction packet has been processed by tc data path. Always fill the new nf_conn_act_ct_ext instance after creating it in nf_conn_act_ct_ext_add(). - Offloading of unidirectional UDP NEW connections is now supported, but ct flow iifidx field is not updated when connection is promoted to bidirectional which can result reply-direction iifidx to be zero when refreshing the connection. Fill in the extension and update flow iifidx before calling flow_offload_refresh(). Fixes: |

New code for 6.7:
* Realtime device subsystem
- Cleanup usage of xfs_rtblock_t and xfs_fsblock_t data types.
- Replace open coded conversions between rt blocks and rt extents with
calls to static inline helpers.
- Replace open coded realtime geometry compuation and macros with helper
functions.
- CPU usage optimizations for realtime allocator.
- Misc. Bug fixes associated with Realtime device.
* Allow read operations to execute while an FICLONE ioctl is being serviced.
* Misc. bug fixes
- Alert user when xfs_droplink() encounters an inode with a link count of zero.
- Handle the case where the allocator could return zero extents when
servicing an fallocate request.

MAINTAINERS: update lists.linuxfoundation.org migrated lists
The mailman-2 system behind lists.linux[-]foundation.org is being retired, so the lists are being migrated to lists.linux.dev. Since both domains belong to LF and setting up proper forwards is possible, the old addresses will continue to work for a while, but all new patches should be sent to the new canonical addresses for each list.
