In ravb_start_xmit(), ravb driver uses u32 variable to store result of
dma_map_single() call. Since ravb hardware has 32-bit address fields in
descriptors, this works properly when mapping is successful - it is
platform's job to provide mapping addresses that fit into hardware
limitations.
However, in failure case dma_map_single() returns DMA_MAPPING_ERROR
constant that is 64-bit when dma_addr_t is 64-bit. Storing this constant
in u32 leads to truncation, and further call to dma_mapping_error()
fails to notice the error.
Fix that by storing result of dma_map_single() in a dma_addr_t
variable.

====================
tls fixes for SPLICE with more hint
Syzbot found a splat where it tried to splice data over a tls socket
with the more hint and sending greater than the number of frags that
fit in a msg scatterlist. This resulted in an error where we do not
correctly send the data when the msg sg is full. The more flag being
just a hint not a strict contract. This then results in the syzbot
warning on the next send.
Edward generated an initial patch for this which checked for a full
msg on entry to the sendmsg hook. This fixed the WARNING, but didn't
fully resolve the issue because the full msg_pl scatterlist was never
sent resulting in a stuck socket. In this series instead avoid the
situation by forcing the send on the splice that fills the scatterlist.
Also in original thread I mentioned it didn't seem to be enough to
simply fix the send on full sg problem. That was incorrect and was
really a bug in my test program that was hanging the test program.
I had setup a repair socket and wasn't handling it correctly so my
tester got stuck.
Thanks. Please review. Fix in patch 1 and test in patch 2.
v2: use SPLICE_F_ flag names instead of cryptic 0xe

A splice with MSG_SPLICE_PAGES will cause tls code to use the
tls_sw_sendmsg_splice path in the TLS sendmsg code to move the user
provided pages from the msg into the msg_pl. This will loop over the
msg until msg_pl is full, checked by sk_msg_full(msg_pl). The user
can also set the MORE flag to hint stack to delay sending until receiving
more pages and ideally a full buffer.
If the user adds more pages to the msg than can fit in the msg_pl
scatterlist (MAX_MSG_FRAGS) we should ignore the MORE flag and send
the buffer anyways.
What actually happens though is we abort the msg to msg_pl scatterlist
setup and then because we forget to set 'full record' indicating we
can no longer consume data without a send we fallthrough to the 'continue'
path which will check if msg_data_left(msg) has more bytes to send and
then attempts to fit them in the already full msg_pl. Then next
iteration of sender doing send will encounter a full msg_pl and throw
the warning in the syzbot report.
To fix simply check if we have a full_record in splice code path and
if not send the msg regardless of MORE flag.

syzbot/KMSAN reports access to uninitialized data from gso_features_check() [1]
The repro use af_packet, injecting a gso packet and hdrlen == 0.
We could fix the issue making gso_features_check() more careful
while dealing with NETIF_F_TSO_MANGLEID in fast path.
Or we can make sure virtio_net_hdr_to_skb() pulls minimal network and
transport headers as intended.
Note that for GSO packets coming from untrusted sources, SKB_GSO_DODGY
bit forces a proper header validation (and pull) before the packet can
hit any device ndo_start_xmit(), thus we do not need a precise disection
at virtio_net_hdr_to_skb() stage.

Clsact/ingress qdisc is not the only one using shared block,
red is also using it. The device tracking was originally introduced
by commit 913b47d3424e ("net/sched: Introduce tc block netdev
tracking infra") for clsact/ingress only. Commit 94e2557d086a ("net:
sched: move block device tracking into tcf_block_get/put_ext()")
mistakenly enabled that for red as well.
Fix that by adding a check for the binder type being clsact when adding
device to the block->ports xarray.

====================
mptcp: better validation of MPTCPOPT_MP_JOIN option
Based on a syzbot report (see 4th patch in the series).
We need to be more explicit about which one of the
following flag is set by mptcp_parse_option():
- OPTION_MPTCP_MPJ_SYN
- OPTION_MPTCP_MPJ_SYNACK
- OPTION_MPTCP_MPJ_ACK
Then select the appropriate values instead of OPTIONS_MPTCP_MPJ
Paolo suggested to do the same for OPTIONS_MPTCP_MPC (5th patch)

OPTIONS_MPTCP_MPC is a combination of three flags.
It would be better to be strict about testing what
flag is expected, at least for code readability.
mptcp_parse_option() already makes the distinction.
- subflow_check_req() should use OPTION_MPTCP_MPC_SYN.
- mptcp_subflow_init_cookie_req() should use OPTION_MPTCP_MPC_ACK.
- subflow_finish_connect() should use OPTION_MPTCP_MPC_SYNACK
- subflow_syn_recv_sock should use OPTION_MPTCP_MPC_ACK

mptcp_parse_option() currently sets OPTIONS_MPTCP_MPJ, for the three
possible cases handled for MPTCPOPT_MP_JOIN option.
OPTIONS_MPTCP_MPJ is the combination of three flags:
- OPTION_MPTCP_MPJ_SYN
- OPTION_MPTCP_MPJ_SYNACK
- OPTION_MPTCP_MPJ_ACK
This is a problem, because backup, join_id, token, nonce and/or hmac fields
could be left uninitialized in some cases.
Distinguish the three cases, as following patches will need this step.

The RZ/G3S SMARC Module has 2 KSZ9131 PHYs. In this setup, the KSZ9131 PHY
is used with the ravb Ethernet driver. It has been discovered that when
bringing the Ethernet interface down/up continuously, e.g., with the
following sh script:
$ while :; do ifconfig eth0 down; ifconfig eth0 up; done
the link speed and duplex are wrong after interrupting the bring down/up
operation even though the Ethernet interface is up. To recover from this
state the following configuration sequence is necessary (executed
manually):
$ ifconfig eth0 down
$ ifconfig eth0 up
The behavior has been identified also on the Microchip SAMA7G5-EK board
which runs the macb driver and uses the same PHY.
The order of PHY-related operations in ravb_open() is as follows:
ravb_open() ->
ravb_phy_start() ->
ravb_phy_init() ->
of_phy_connect() ->
phy_connect_direct() ->
phy_attach_direct() ->
phy_init_hw() ->
phydev->drv->soft_reset()
phydev->drv->config_init()
phydev->drv->config_intr()
phy_resume()
kszphy_resume()
The order of PHY-related operations in ravb_close is as follows:
ravb_close() ->
phy_stop() ->
phy_suspend() ->
kszphy_suspend() ->
genphy_suspend()
// set BMCR_PDOWN bit in MII_BMCR
In genphy_suspend() setting the BMCR_PDWN bit in MII_BMCR switches the PHY
to Software Power-Down (SPD) mode (according to the KSZ9131 datasheet).
Thus, when opening the interface after it has been previously closed (via
ravb_close()), the phydev->drv->config_init() and
phydev->drv->config_intr() reach the KSZ9131 PHY driver via the
ksz9131_config_init() and kszphy_config_intr() functions.
KSZ9131 specifies that the MII management interface remains operational
during SPD (Software Power-Down), but (according to manual):
- Only access to the standard registers (0 through 31) is supported.
- Access to MMD address spaces other than MMD address space 1 is possible
if the spd_clock_gate_override bit is set.
- Access to MMD address space 1 is not possible.
The spd_clock_gate_override bit is not used in the KSZ9131 driver.
ksz9131_config_init() configures RGMII delay, pad skews and LEDs by
accessesing MMD registers other than those in address space 1.
The datasheet for the KSZ9131 does not specify what happens if registers
from an unsupported address space are accessed while the PHY is in SPD.
To fix the issue the .soft_reset method has been instantiated for KSZ9131,
too. This resets the PHY to the default state before doing any
configurations to it, thus switching it out of SPD.

The HW has the capability to check each frame if it is a PTP frame,
which domain it is, which ptp frame type it is, different ip address in
the frame. And if one of these checks fail then the frame is not
timestamp. Most of these checks were disabled except checking the field
minorVersionPTP inside the PTP header. Meaning that once a partner sends
a frame compliant to 8021AS which has minorVersionPTP set to 1, then the
frame was not timestamp because the HW expected by default a value of 0
in minorVersionPTP.
Fix this issue by removing this check so the userspace can decide on this.

amt driver uses skb->cb for storing tunnel information.
This job is worked before TC layer and then amt driver load tunnel info
from skb->cb after TC layer.
So, its cb area should not be overwrapped with CB area used by TC.
In order to not use cb area used by TC, it skips the biggest cb
structure used by TC, which was qdisc_skb_cb.
But it's not anymore.
Currently, biggest structure of TC's CB is tc_skb_cb.
So, it should skip size of tc_skb_cb instead of qdisc_skb_cb.

Sanjuán García, Jorge says:
====================
net: ethernet: ti: am65-cpsw: Allow for MTU values
The am65-cpsw-nuss driver has a fixed definition for the maximum ethernet
frame length of 1522 bytes (AM65_CPSW_MAX_PACKET_SIZE). This limits the switch
ports to only operate at a maximum MTU of 1500 bytes. When combining this CPSW
switch with a DSA switch connected to one of its ports this limitation shows up.
The extra 8 bytes the DSA subsystem adds internally to the ethernet frame
create resulting frames bigger than 1522 bytes (1518 for non VLAN + 8 for DSA
stuff) so they get dropped by the switch.
One of the issues with the the am65-cpsw-nuss driver is that the network device
max_mtu was being set to the same fixed value defined for the max total frame
length (1522 bytes). This makes the DSA subsystem believe that the MTU of the
interface can be set to 1508 bytes to make room for the extra 8 bytes of the DSA
headers. However, all packages created assuming the 1500 bytes payload get
dropped by the switch as oversized.
This series offers a solution to this problem. The max_mtu advertised on the
network device and the actual max frame size configured on the switch registers
are made consistent by letting the extra room needed for the ethernet headers
and the frame checksum (22 bytes including VLAN).

The value of AM65_CPSW_MAX_PACKET_SIZE represents the maximum length
of a received frame. This value is written to the register
AM65_CPSW_PORT_REG_RX_MAXLEN.
The maximum MTU configured on the network device should then leave
some room for the ethernet headers and frame check. Otherwise, if
the network interface is configured to its maximum mtu possible,
the frames will be larger than AM65_CPSW_MAX_PACKET_SIZE and will
get dropped as oversized.
The switch supports ethernet frame sizes between 64 and 2024 bytes
(including VLAN) as stated in the technical reference manual, so
define AM65_CPSW_MAX_PACKET_SIZE with that maximum size.

The patch broke:

This last command is useful to be able to enslave an interface with only
one netlink message.
After discussion, there is no good reason to support:
> ip link set dummy0 down
> ip link set dummy0 master bond0 up
because the bond interface already set the slave up when it is up.

rxrpc normally has the Don't Fragment flag set on the UDP packets it
transmits, except when it has decided that DATA packets aren't getting
through - in which case it turns it off just for the DATA transmissions.
This can be a problem, however, for RESPONSE packets that convey
authentication and crypto data from the client to the server as ticket may
be larger than can fit in the MTU.
In such a case, rxrpc gets itself into an infinite loop as the sendmsg
returns an error (EMSGSIZE), which causes rxkad_send_response() to return
-EAGAIN - and the CHALLENGE packet is put back on the Rx queue to retry,
leading to the I/O thread endlessly attempting to perform the transmission.
Fix this by disabling DF on RESPONSE packets for now. The use of DF and
best data MTU determination needs reconsidering at some point in the
future.

After the blamed commit, we started doing this dereference for every
NETDEV_CHANGEUPPER and NETDEV_PRECHANGEUPPER event in the system.
static inline struct dsa_port *dsa_user_to_port(const struct net_device *dev)
{
struct dsa_user_priv *p = netdev_priv(dev);
return p->dp;
}
Which is obviously bogus, because not all net_devices have a netdev_priv()
of type struct dsa_user_priv. But struct dsa_user_priv is fairly small,
and p->dp means dereferencing 8 bytes starting with offset 16. Most
drivers allocate that much private memory anyway, making our access not
fault, and we discard the bogus data quickly afterwards, so this wasn't
caught.
But the dummy interface is somewhat special in that it calls
alloc_netdev() with a priv size of 0. So every netdev_priv() dereference
is invalid, and we get this when we emit a NETDEV_PRECHANGEUPPER event
with a VLAN as its new upper:
$ ip link add dummy1 type dummy
$ ip link add link dummy1 name dummy1.100 type vlan id 100

The rules to link selftests are:

The intel test robot uses only selftest's Makefile, not the top linux
Makefile:
> make W=1 O=/tmp/kselftest -C tools/testing/selftests
So, $(LINK.c) is determined by environment, rather than by kernel
Makefiles. On my machine (as well as other people that ran tcp-ao
selftests) GNU/Make implicit definition does use $(LDFLAGS):
> [dima@Mindolluin ~]$ make -p -f/dev/null | grep '^LINK.c\>'
> make: *** No targets. Stop.
> LINK.c = $(CC) $(CFLAGS) $(CPPFLAGS) $(LDFLAGS) $(TARGET_ARCH)
But, according to build robot report, it's not the case for them.
While I could just avoid using pre-defined $(LINK.c), it's also used by
selftests/lib.mk by default.
Anyways, according to GNU/Make documentation [1], I should have used
$(LDLIBS) instead of $(LDFLAGS) in the first place, so let's just do it:
> LDFLAGS
> Extra flags to give to compilers when they are supposed to invoke
> the linker, ‘ld’, such as -L. Libraries (-lfoo) should be added
> to the LDLIBS variable instead.
> LDLIBS
> Library flags or names given to compilers when they are supposed
> to invoke the linker, ‘ld’. LOADLIBES is a deprecated (but still
> supported) alternative to LDLIBS. Non-library linker flags, such
> as -L, should go in the LDFLAGS variable.

I missed that Dany uses a different email address
when tagging patches (drt@linux.ibm.com)
and asked him if he's still actively working on ibmvnic.
He doesn't really fall under our removal criteria,
but he admitted that he already moved on to other projects.

Pull networking updates from Paolo Abeni:
"The most interesting thing is probably the networking structs
reorganization and a significant amount of changes is around
self-tests.
Core & protocols:
- Analyze and reorganize core networking structs (socks, netdev,
netns, mibs) to optimize cacheline consumption and set up build
time warnings to safeguard against future header changes
This improves TCP performances with many concurrent connections up
to 40%
- Add page-pool netlink-based introspection, exposing the memory
usage and recycling stats. This helps indentify bad PP users and
possible leaks
- Refine TCP/DCCP source port selection to no longer favor even
source port at connect() time when IP_LOCAL_PORT_RANGE is set. This
lowers the time taken by connect() for hosts having many active
connections to the same destination
- Refactor the TCP bind conflict code, shrinking related socket
structs
- Refactor TCP SYN-Cookie handling, as a preparation step to allow
arbitrary SYN-Cookie processing via eBPF
- Tune optmem_max for 0-copy usage, increasing the default value to
128KB and namespecifying it
- Allow coalescing for cloned skbs coming from page pools, improving
RX performances with some common configurations
- Reduce extension header parsing overhead at GRO time
- Add bridge MDB bulk deletion support, allowing user-space to
request the deletion of matching entries
- Reorder nftables struct members, to keep data accessed by the
datapath first
- Introduce TC block ports tracking and use. This allows supporting
multicast-like behavior at the TC layer
- Remove UAPI support for retired TC qdiscs (dsmark, CBQ and ATM) and
classifiers (RSVP and tcindex)
- More data-race annotations
- Extend the diag interface to dump TCP bound-only sockets
- Conditional notification of events for TC qdisc class and actions
- Support for WPAN dynamic associations with nearby devices, to form
a sub-network using a specific PAN ID
- Implement SMCv2.1 virtual ISM device support
- Add support for Batman-avd mulicast packet type
BPF:
- Tons of verifier improvements:
- BPF register bounds logic and range support along with a large
test suite
- log improvements
- complete precision tracking support for register spills
- track aligned STACK_ZERO cases as imprecise spilled registers.
This improves the verifier "instructions processed" metric from
single digit to 50-60% for some programs
- support for user's global BPF subprogram arguments with few
commonly requested annotations for a better developer
experience
- support tracking of BPF_JNE which helps cases when the compiler
transforms (unsigned) "a > 0" into "if a == 0 goto xxx" and the
like
- several fixes
- Add initial TX metadata implementation for AF_XDP with support in
mlx5 and stmmac drivers. Two types of offloads are supported right
now, that is, TX timestamp and TX checksum offload
- Fix kCFI bugs in BPF all forms of indirect calls from BPF into
kernel and from kernel into BPF work with CFI enabled. This allows
BPF to work with CONFIG_FINEIBT=y
- Change BPF verifier logic to validate global subprograms lazily
instead of unconditionally before the main program, so they can be
guarded using BPF CO-RE techniques
- Support uid/gid options when mounting bpffs
- Add a new kfunc which acquires the associated cgroup of a task
within a specific cgroup v1 hierarchy where the latter is
identified by its id
- Extend verifier to allow bpf_refcount_acquire() of a map value
field obtained via direct load which is a use-case needed in
sched_ext
- Add BPF link_info support for uprobe multi link along with bpftool
integration for the latter
- Support for VLAN tag in XDP hints
- Remove deprecated bpfilter kernel leftovers given the project is
developed in user-space (https://github.com/facebook/bpfilter)
Misc:
- Support for parellel TC self-tests execution
- Increase MPTCP self-tests coverage
- Updated the bridge documentation, including several so-far
undocumented features
- Convert all the net self-tests to run in unique netns, to avoid
random failures due to conflict and allow concurrent runs
- Add TCP-AO self-tests
- Add kunit tests for both cfg80211 and mac80211
- Autogenerate Netlink families documentation from YAML spec
- Add yml-gen support for fixed headers and recursive nests, the tool
can now generate user-space code for all genetlink families for
which we have specs
- A bunch of additional module descriptions fixes
- Catch incorrect freeing of pages belonging to a page pool
Driver API:
- Rust abstractions for network PHY drivers; do not cover yet the
full C API, but already allow implementing functional PHY drivers
in rust
- Introduce queue and NAPI support in the netdev Netlink interface,
allowing complete access to the device <> NAPIs <> queues
relationship
- Introduce notifications filtering for devlink to allow control
application scale to thousands of instances
- Improve PHY validation, requesting rate matching information for
each ethtool link mode supported by both the PHY and host
- Add support for ethtool symmetric-xor RSS hash
- ACPI based Wifi band RFI (WBRF) mitigation feature for the AMD
platform
- Expose pin fractional frequency offset value over new DPLL generic
netlink attribute
- Convert older drivers to platform remove callback returning void
- Add support for PHY package MMD read/write

Pull s390 updates from Alexander Gordeev:
- Add machine variable capacity information to /proc/sysinfo.
- Limit the waste of page tables and always align vmalloc area size and
base address on segment boundary.
- Fix a memory leak when an attempt to register interruption sub class
(ISC) for the adjunct-processor (AP) guest failed.
- Reset response code AP_RESPONSE_INVALID_GISA to understandable by
guest AP_RESPONSE_INVALID_ADDRESS in response to a failed
interruption sub class (ISC) registration attempt.
- Improve reaction to adjunct-processor (AP)
AP_RESPONSE_OTHERWISE_CHANGED response code when enabling interrupts
on behalf of a guest.
- Fix incorrect sysfs 'status' attribute of adjunct-processor (AP)
queue device bound to the vfio_ap device driver when the mediated
device is attached to a guest, but the queue device is not passed
through.
- Rework struct ap_card to hold the whole adjunct-processor (AP) card
hardware information. As result, all the ugly bit checks are replaced
by simple evaluations of the required bit fields.
- Improve handling of some weird scenarios between service element (SE)
host and SE guest with adjunct-processor (AP) pass-through support.
- Change local_ctl_set_bit() and local_ctl_clear_bit() so they return
the previous value of the to be changed control register. This is
useful if a bit is only changed temporarily and the previous content
needs to be restored.
- The kernel starts with machine checks disabled and is expected to
enable it once trap_init() is called. However the implementation
allows machine checks early. Consistently enable it in trap_init()
only.
- local_mcck_disable() and local_mcck_enable() assume that machine
checks are always enabled. Instead implement and use
local_mcck_save() and local_mcck_restore() to disable machine checks
and restore the previous state.
- Modification of floating point control (FPC) register of a traced
process using ptrace interface may lead to corruption of the FPC
register of the tracing process. Fix this.
- kvm_arch_vcpu_ioctl_set_fpu() allows to set the floating point
control (FPC) register in vCPU, but may lead to corruption of the FPC
register of the host process. Fix this.
- Use READ_ONCE() to read a vCPU floating point register value from the
memory mapped area. This avoids that, depending on code generation, a
different value is tested for validity than the one that is used.
- Get rid of test_fp_ctl(), since it is quite subtle to use it
correctly. Instead copy a new floating point control register value
into its save area and test the validity of the new value when
loading it.
- Remove superfluous save_fpu_regs() call.
- Remove s390 support for ARCH_WANTS_DYNAMIC_TASK_STRUCT. All machines
provide the vector facility since many years and the need to make the
task structure size dependent on the vector facility does not exist.
- Remove the "novx" kernel command line option, as the vector code runs
without any problems since many years.
- Add the vector facility to the z13 architecture level set (ALS). All
hypervisors support the vector facility since many years. This allows
compile time optimizations of the kernel.
- Get rid of MACHINE_HAS_VX and replace it with cpu_has_vx(). As
result, the compiled code will have less runtime checks and less
code.
- Convert pgste_get_lock() and pgste_set_unlock() ASM inlines to C.
- Convert the struct subchannel spinlock from pointer to member.

Pull asm-generic cleanups from Arnd Bergmann:
"A series from Baoquan He cleans up the asm-generic/io.h to remove the
ioremap_uc() definition from everything except x86, which still needs
it for pre-PAT systems. This series notably contains a patch from
Jiaxun Yang that converts MIPS to use asm-generic/io.h like every
other architecture does, enabling future cleanups.
Some of my own patches fix -Wmissing-prototype warnings in
architecture specific code across several architectures. This is now
needed as the warning is enabled by default. There are still some
remaining warnings in minor platforms, but the series should catch
most of the widely used ones make them more consistent with one
another.
David McKay fixes a bug in __generic_cmpxchg_local() when this is used
on 64-bit architectures. This could currently only affect parisc64 and
sparc64.
Additional cleanups address from Linus Walleij, Uwe Kleine-König,
Thomas Huth, and Kefeng Wang help reduce unnecessary inconsistencies
between architectures"
