====================
pull-request: can-next 2025-07-25
The first patch is by Khaled Elnaggar and converts the janz-ican3
driver's fwinfo_show() to sysfs_emit().
Vincent Mailhol contributes 3 patches that first fix a warning in the
ti_hecc driver and then add missing COMPILE_TEST more compile
coverage to the ti_hecc and tscan1 driver.
Randy Dunlap's patch let's the tscan1 driver depend on PC104.
A patch by Luis Felipe Hernandez fixes a kernel-doc error in the
ctucanfd driver.
Jimmy Assarsson contributes 10 patches for the kvaser_pciefd and 11
for the kvaser_usb driver. Both series simplify the identification of
physical the CAN interfaces and add devlink support to get information
about the running firmware.

Tony Nguyen says:
====================
libie: commonize adminq structure
Michal Swiatkowski says:
It is a prework to allow reusing some specific Intel code (eq. fwlog).
Move common *_aq_desc structure to libie header and changing
it in ice, ixgbe, i40e and iavf.
Only generic adminq commands can be easily moved to common header, as
rest is slightly different. Format remains the same. It will be better
to correctly move it when it will be needed to commonize other part of
the code.
Move *_aq_str() to new libie module (libie_adminq) and use it across
drivers. The functions are exactly the same in each driver. Some more
adminq helpers/functions can be moved to libie_adminq when needed.
* '100GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/next-queue:
i40e: use libie_aq_str
iavf: use libie_aq_str
ice: use libie_aq_str
libie: add adminq helper for converting err to str
iavf: use libie adminq descriptors
i40e: use libie adminq descriptors
ixgbe: use libie adminq descriptors
ice, libie: move generic adminq descriptors to lib

Currently, packets dropped by pfifo_fast due to queue overflow are
marked with a generic SKB_DROP_REASON_QDISC_DROP in __dev_xmit_skb().
This patch adds explicit drop reason SKB_DROP_REASON_QDISC_OVERLIMIT
for queue-full cases, providing better distinction from other qdisc drops.

[ 45.800747][ T9787] Kernel panic - not syncing: Fatal exception
The hfs_fill_super() calls hfs_mdb_get() method that tries
to construct Extents Tree and Catalog Tree:
HFS_SB(sb)->ext_tree = hfs_btree_open(sb, HFS_EXT_CNID, hfs_ext_keycmp);
if (!HFS_SB(sb)->ext_tree) {
pr_err("unable to open extent tree\n");
goto out;
}
HFS_SB(sb)->cat_tree = hfs_btree_open(sb, HFS_CAT_CNID, hfs_cat_keycmp);
if (!HFS_SB(sb)->cat_tree) {
pr_err("unable to open catalog tree\n");
goto out;
}
However, hfs_btree_open() calls read_mapping_page() that
calls hfs_get_block(). And this method calls hfs_ext_read_extent():
static int hfs_ext_read_extent(struct inode *inode, u16 block)
{
struct hfs_find_data fd;
int res;
if (block >= HFS_I(inode)->cached_start &&
block < HFS_I(inode)->cached_start + HFS_I(inode)->cached_blocks)
return 0;
res = hfs_find_init(HFS_SB(inode->i_sb)->ext_tree, &fd);
if (!res) {
res = __hfs_ext_cache_extent(&fd, inode, block);
hfs_find_exit(&fd);
}
return res;
}
The problem here that hfs_find_init() is trying to use
HFS_SB(inode->i_sb)->ext_tree that is not initialized yet.
It will be initailized when hfs_btree_open() finishes
the execution.
The patch adds checking of tree pointer in hfs_find_init()
and it reworks the logic of hfs_btree_open() by reading
the b-tree's header directly from the volume. The read_mapping_page()
is exchanged on filemap_grab_folio() that grab the folio from
mapping. Then, sb_bread() extracts the b-tree's header
content and copy it into the folio.

This patch introduces is_bnode_offset_valid() method that checks
the requested offset value. Also, it introduces
check_and_correct_requested_length() method that checks and
correct the requested length (if it is necessary). These methods
are used in hfs_bnode_read(), hfs_bnode_write(), hfs_bnode_clear(),
hfs_bnode_copy(), and hfs_bnode_move() with the goal to prevent
the access out of allocated memory and triggering the crash.

The reason of the issue that code doesn't check the correctness
of the requested offset and length. As a result, incorrect value
of offset or/and length could result in access out of allocated
memory.
This patch introduces is_bnode_offset_valid() method that checks
the requested offset value. Also, it introduces
check_and_correct_requested_length() method that checks and
correct the requested length (if it is necessary). These methods
are used in hfsplus_bnode_read(), hfsplus_bnode_write(),
hfsplus_bnode_clear(), hfsplus_bnode_copy(), and hfsplus_bnode_move()
with the goal to prevent the access out of allocated memory
and triggering the crash.

====================
net: Add sockaddr_inet unified address structure
Repeating patch 1, as it has the rationale:
There are cases in networking (e.g. wireguard, sctp) where a union is
used to provide coverage for either IPv4 or IPv6 network addresses,
and they include an embedded "struct sockaddr" as well (for "sa_family"
and raw "sa_data" access). The current struct sockaddr contains a
flexible array, which means these unions should not be further embedded
in other structs because they do not technically have a fixed size (and
are generating warnings for the coming -Wflexible-array-not-at-end flag
addition). But the future changes to make struct sockaddr a fixed size
(i.e. with a 14 byte sa_data member) make the "sa_data" uses with an IPv6
address a potential place for the compiler to get upset about object size
mismatches. Therefore, we need a sockaddr that cleanly provides both an
sa_family member and an appropriately fixed-sized sa_data member that does
not bloat member usage via the potential alternative of sockaddr_storage
to cover both IPv4 and IPv6, to avoid unseemly churn in the affected code
bases.
Introduce sockaddr_inet as a unified structure for holding both IPv4 and
IPv6 addresses (i.e. large enough to accommodate sockaddr_in6).
The structure is defined in linux/in6.h since its max size is sized
based on sockaddr_in6 and provides a more specific alternative to the
generic sockaddr_storage for IPv4 with IPv6 address family handling.
The "sa_family" member doesn't use the sa_family_t type to avoid needing
layer violating header inclusions.
Also includes the replacements for wireguard and sctp.

As part of the removal of the variably-sized sockaddr for kernel
internals, replace struct sockaddr with sockaddr_inet in the sctp_addr
union.
No binary changes; the union size remains unchanged due to sockaddr_inet
matching the size of sockaddr_in6.

Remote IPsec tunnel endpoint may refer to a network segment that is
not directly connected to the host. In such a case, IPsec tunnel
endpoints are connected to a router and reachable via a routing path.
In IPsec packet offload mode, HW is initialized with the MAC address
of both IPsec tunnel endpoints.
Extend the current IPsec init MACs procedure to resolve nexthop for
routed networks. Direct neighbour lookup and probe is still used
for directly connected networks and as a fallback mechanism if fib
lookup fails.

The hfsplus_uni2asc() method operates by struct hfsplus_unistr:
struct hfsplus_unistr {
__be16 length;
hfsplus_unichr unicode[HFSPLUS_MAX_STRLEN];
} __packed;
where HFSPLUS_MAX_STRLEN is 255 bytes. The issue happens if length
of the structure instance has value bigger than 255 (for example,
65283). In such case, pointer on unicode buffer is going beyond of
the allocated memory.
The patch fixes the issue by checking the length value of
hfsplus_unistr instance and using 255 value in the case if length
value is bigger than HFSPLUS_MAX_STRLEN. Potential reason of such
situation could be a corruption of Catalog File b-tree's node.

hfsplus_submit_bio() called by hfsplus_sync_fs() uses bdev_virt_rw() which
in turn uses submit_bio_wait() to submit the BIO.
But submit_bio_wait() already sets the REQ_SYNC flag on the BIO so there
is no need for setting the flag in hfsplus_sync_fs() when calling
hfsplus_submit_bio().

The events sched_move_numa, sched_stick_numa and sched_swap_numa are only
called when CONFIG_NUMA_BALANCING is configured. As each event can take up
to 5K of memory in text and meta data regardless if they are used or not,
they should not be defined when unused.
Move the #ifdef CONFIG_NUMA_BALANCING to hide these events as well.

Rework the read and write code paths in the driver to support operation
in atomic contexts. To achieve this, the driver must not rely on IRQs
or perform any scheduling, e.g., via a sleep or schedule routine.
Implement atomic, sleep-free, and IRQ-less operation. This increases
complexity but is necessary for atomic I2C transfers required by some
hardware configurations, e.g., to trigger reboots on an external PMIC chip.

The I2C controllers in most Rockchip SoCs are part of power domains that
are always powered on, i.e. PD_BUS or PD_PMU. These always powered
on power domains have typically not been described in the device tree.
Because these power domains have been left out of the device tree there
has not been any real need to properly describe the I2C controllers
power domain.
On RK3528 the I2C controllers are spread out among the described
PD_RKVENC, PD_VO and PD_VPU power domains. However, one I2C controller
belong to an undescribed always powered on power domain.
Add support to describe an optional power-domains for the I2C
controllers in Rockchip SoCs.

net: dsa: b53: mmap: Add bcm63xx EPHY power control
The gpio controller on some bcm63xx SoCs has a register for
controlling functionality of the internal fast ethernet phys.
These patches allow the b53 driver to enable/disable phy
power.
The register also contains reset bits which will be set by
a reset driver in another patch series:

Because of the way read access support is implemented, read access
interruptions are only triggered at privilege levels 2 and 3. The
kernel executes at privilege level 0, so __get_user() never triggers
a read access interruption (code 26). Thus, it is currently possible
for user code to access a read protected address via a system call.
Fix this by probing read access rights at privilege level 3 (PRIV_USER)
and setting __gu_err to -EFAULT (-14) if access isn't allowed.
Note the cmpiclr instruction does a 32-bit compare because COND macro
doesn't work inside asm.

We use load and stbys,e instructions to trigger memory reference
interruptions without writing to memory. Because of the way read
access support is implemented, read access interruptions are only
triggered at privilege levels 2 and 3. The kernel and gateway
page execute at privilege level 0, so this code never triggers
a read access interruption. Thus, it is currently possible for
user code to execute a LWS compare and swap operation at an
address that is read protected at privilege level 3 (PRIV_USER).
Fix this by probing read access rights at privilege level 3 and
branching to lws_fault if access isn't allowed.

Because of the way the _PAGE_READ is handled in the parisc PTE, an
access interruption is not generated when the kernel reads from a
region where the _PAGE_READ is zero. The current code was written
assuming read access faults would also occur in the kernel.
This change adds user access checks to raw_copy_from_user(). The
prober_user() define checks whether user code has read access to
a virtual address. Note that page faults are not handled in the
exception support for the probe instruction. For this reason, we
precede the probe by a ldb access check.

The following testcase exposed a problem with our read access checks
in get_user() and raw_copy_from_user():
#include <stdint.h>
#include <stddef.h>
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <unistd.h>
#include <errno.h>
#include <sys/mman.h>
#include <sys/types.h>
int main(int argc, char **argv)
{
unsigned long page_size = sysconf(_SC_PAGESIZE);
char *p = malloc(3 * page_size);
char *p_aligned;
/* initialize memory region. If not initialized, write syscall below will correctly return EFAULT. */
if (1)
memset(p, 'X', 3 * page_size);
p_aligned = (char *) ((((uintptr_t) p) + (2*page_size - 1)) & ~(page_size - 1));
/* Drop PROT_READ protection. Kernel and userspace should fault when accessing that memory region */
mprotect(p_aligned, page_size, PROT_NONE);
/* the following write() should return EFAULT, since PROT_READ was dropped by previous mprotect() */
int ret = write(2, p_aligned, 1);
if (!ret || errno != EFAULT)
printf("\n FAILURE: write() did not returned expected EFAULT value\n");
return 0;
}
Because of the way _PAGE_READ is handled, kernel code never generates
a read access fault when it access a page as the kernel privilege level
is always less than PL1 in the PTE.
This patch reworks the comments in the make_insert_tlb macro to try
to make this clearer.

Many of the original rtla tests included durations of 1 minute and 30
seconds. Experience has shown this is unnecessary, since 10 seconds as
waiting time for samples to appear.
Change duration of all rtla tests to at most 10 seconds. This speeds up
testing significantly.
Before:
$ make check
All tests successful.
Files=3, Tests=54, 536 wallclock secs
( 0.03 usr 0.00 sys + 20.31 cusr 22.02 csys = 42.36 CPU)
