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:
> $(OUTPUT)/%_ipv4: %.c
> $(LINK.c) $^ $(LDLIBS) -o $@
>
> $(OUTPUT)/%_ipv6: %.c
> $(LINK.c) -DIPV6_TEST $^ $(LDLIBS) -o $@
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.

For the normal read/write path, we have already locked the ring
submission side when assigning the file. This causes branch
mispredictions when we then check and try and lock again in
io_req_set_rsrc_node(). As this is a very hot path, this matters.
Add a basic helper that already assumes we already have it locked,
and use that in io_file_get_fixed().

already supported chips.
The other six new SoCs are all part of existing arm64 families, but
are somewhat more interesting:
- Samsung ExynosAutov920 is an automotive chip, and the first one we
support based on the Cortex-A78AE core with lockstep mode.
- Google gs101 (Tensor G1) is the chip used in a number of Pixel
phones, and is grouped with Samsung Exynos here since it is based
on the same SoC design, sharing most of its IP blocks with that
series.
- MediaTek MT8188 is a new chip used for mid-range tablets and
Chromebooks, using two Cortex-A78 cores where the older MT8195 had
four of them.
- Qualcomm SM8650 (Snapdragon 8 Gen 3) is their current top range
phone SoC and the first supported chip based on Cortex-X4,
Cortex-A720 and Cortex-A520.
- Qualcomm X1E80100 (Snapdragon X Elite) in turn is the latest Laptop
chip using the custom Oryon cores.
- Unisoc UMS9620 (Tanggula 7 series) is a 5G phone SoC based on
Cortex-A76 and Cortex-A55
In terms of boards, we have
- Five old Microsoft Lumia phones, the HTC One Mini 2, Motorola Moto
G 4G, and Huawei Honor 5X/GR5, all based on Snapdragon SoCs.

RK2023, Powkiddy X55) along with the Sonoff iHost Smart Home Hub
and a few Rockchips SBCs
- Some ComXpress boards based on Marvell CN913x, which is the

git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next
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

The recently added driver uses the firmware loader mechanism but causes
a link failure when that is in a loadable module while thp7312 itself
is built-in:
arm-linux-gnueabi-ld: drivers/media/i2c/thp7312.o: in function `thp7312_probe':
thp7312.c:(.text+0x4164): undefined reference to `firmware_upload_register'
Select the required Kconfig symbol. Note that the driver specifically
needs the firmware upload interface that is controlled by CONFIG_FW_UPLOAD,
but there is no link failure when that is disabled because the interfaces
are stubbed out here.

The code which validates floating point control register contents was
reworked with commit 702644249d3e ("s390/fpu: get rid of test_fp_ctl()").
There is still a comment which refers to the old implementation - remove it
in order to avoid confusion.

The zpci_get_max_write_size() helper is used to determine the maximum
size a PCI store or load can use at a given __iomem address.
For the PCI block store the following restrictions apply:
1. The dst + len must not cross a 4K boundary in the (pseudo-)MMIO space
2. len must not exceed ZPCI_MAX_WRITE_SIZE
3. len must be a multiple of 8 bytes
4. The src address must be double word (8 byte) aligned
5. The dst address must be double word (8 byte) aligned
Otherwise only a normal PCI store which takes its src value from
a register can be used. For these PCI store restriction 1 still applies.
Similarly 1 also applies to PCI loads.
It turns out zpci_max_write_size() instead implements stricter
conditions which prevents PCI block stores from being used where they
can and should be used. In particular instead of conditions 4 and 5 it
wrongly enforces both dst and src to be size aligned. This indirectly
covers condition 1 but also prevents many legal PCI block stores.
On top of the functional shortcomings the zpci_get_max_write_size() is
misnamed as it is used for both read and write size calculations. Rename
it to zpci_get_max_io_size() and implement the listed conditions
explicitly.

Following commit dccf78d39f10 ("kernel/Kconfig.kexec: drop
select of KEXEC for CRASH_DUMP") also drop automatic KEXEC
selection for s390 while set CONFIG_KEXEC=y explicitly for
defconfig and debug_defconfig targets. zfcpdump_defconfig
target gets CONFIG_KEXEC unset as result, which is right
and consistent with CONFIG_KEXEC_FILE besides.

31 bit support has been removed from the kernel more than eight years
ago. The last 31 bit distribution is many years older. There shouldn't be
any 31 bit code around anymore.
Therefore avoid providing an unused and only partially tested user space
interface and change the default for CONFIG_COMPAT from "yes" to "no".

Wrap up the data pointer/num sanity and __iommu_copy_struct_from_user()
call for iommu drivers to copy driver specific data at a specific location
in the struct iommu_user_data_array.
And expect it to be used in cache_invalidate_user ops for example.
