During the introduction of struct bpf_net_context handling for
XDP-redirect, the tun driver has been missed.
Jakub also pointed out that there is another call chain to
do_xdp_generic() originating from netif_receive_skb() and drivers may
use it outside from the NAPI context.
Set the bpf_net_context before invoking BPF XDP program within the TUN
driver. Set the bpf_net_context also in do_xdp_generic() if a xdp
program is available.

Some devices with MediaTek SoCs don't use the first but only the second
MAC in the chip. Especially with MT7981 which got a built-in 1GE PHY
connected to the second MAC this is quite common.
Make sure to reset and enable PSE also in those cases by skipping gaps
using 'continue' instead of aborting the loop using 'break'.

The Makefile open-codes compiler invocations that ../lib.mk already
provides.
Avoid this by using a Make feature that allows setting per-target
variables, which in this case are: CFLAGS and LDFLAGS. This approach
generates the exact same compiler invocations as before, but removes all
of the code duplication, along with the quirky mangled variable names.
So now the Makefile is smaller, less unusual, and easier to read.
The new dependencies are listed after including lib.mk, in order to
let lib.mk provide the first target ("all:"), and are grouped together
with their respective source file dependencies, for visual clarity.

There were a couple of errors here:
1. TEST_GEN_PROGS was incorrectly prepending $(OUTPUT) to each program
to be built. However, lib.mk already does that because it assumes "bare"
program names are passed in, so this ended up creating
$(OUTPUT)/$(OUTPUT)/file.c, which of course won't work as intended.
2. lib.mk was included before TEST_GEN_PROGS was set, which led to
lib.mk's "all:" target not seeing anything to rebuild.
So nothing worked, which caused the author to force things by creating
an "all:" target locally--while still including ../lib.mk.
Fix all of this by including ../lib.mk at the right place, and removing
the $(OUTPUT) prefix to the programs to be built, and removing the
duplicate "all:" target.

When building with clang, via:
make LLVM=1 -C tools/testing/selftests
...there are several warnings, and an error. This fixes all of those and
allows these tests to run and pass.
1. Fix linker error (undefined reference to memcpy) by providing a local
version of memcpy.
2. clang complains about using this form:
if (g = h & 0xf0000000)
...so factor out the assignment into a separate step.
3. The code is passing a signed const char* to elf_hash(), which expects
a const unsigned char *. There are several callers, so fix this at
the source by allowing the function to accept a signed argument, and
then converting to unsigned operations, once inside the function.
4. clang doesn't have __attribute__((externally_visible)) and generates
a warning to that effect. Fortunately, gcc 12 and gcc 13 do not seem
to require that attribute in order to build, run and pass tests here,
so remove it.

The nr_dentry_negative counter is intended to only account negative
dentries that are present on the superblock LRU. Therefore, the LRU
add, remove and isolate helpers modify the counter based on whether
the dentry is negative, but the shrinker list related helpers do not
modify the counter, and the paths that change a dentry between
positive and negative only do so if DCACHE_LRU_LIST is set.
The problem with this is that a dentry on a shrinker list still has
DCACHE_LRU_LIST set to indicate ->d_lru is in use. The additional
DCACHE_SHRINK_LIST flag denotes whether the dentry is on LRU or a
shrink related list. Therefore if a relevant operation (i.e. unlink)
occurs while a dentry is present on a shrinker list, and the
associated codepath only checks for DCACHE_LRU_LIST, then it is
technically possible to modify the negative dentry count for a
dentry that is off the LRU. Since the shrinker list related helpers
do not modify the negative dentry count (because non-LRU dentries
should not be included in the count) when the dentry is ultimately
removed from the shrinker list, this can cause the negative dentry
count to become permanently inaccurate.
This problem can be reproduced via a heavy file create/unlink vs.
drop_caches workload. On an 80xcpu system, I start 80 tasks each
running a 1k file create/delete loop, and one task spinning on
drop_caches. After 10 minutes or so of runtime, the idle/clean cache
negative dentry count increases from somewhere in the range of 5-10
entries to several hundred (and increasingly grows beyond
nr_dentry_unused).
Tweak the logic in the paths that turn a dentry negative or positive
to filter out the case where the dentry is present on a shrink
related list. This allows the above workload to maintain an accurate
negative dentry count.

The request pointer had been changed earlier to point to a lock entry
that was added to the inode's list. However, before the tracepoint could
fire, another task raced in and freed that lock.
Fix this by moving the tracepoint inside the spinlock, which should

This is the third version of this patch series, in which another patch set
is subsumed into this one to avoid confusing the two patch sets.
(https://patchwork.kernel.org/project/linux-fsdevel/list/?series=854914)
We've been testing ondemand mode for cachefiles since January, and we're
almost done. We hit a lot of issues during the testing period, and this
patch series fixes some of the issues. The patches have passed internal
testing without regression.
The following is a brief overview of the patches, see the patches for
more details.
Patch 1-2: Add fscache_try_get_volume() helper function to avoid
fscache_volume use-after-free on cache withdrawal.
Patch 3: Fix cachefiles_lookup_cookie() and cachefiles_withdraw_cache()
concurrency causing cachefiles_volume use-after-free.
Patch 4: Propagate error codes returned by vfs_getxattr() to avoid
endless loops.
Patch 5-7: A read request waiting for reopen could be closed maliciously
before the reopen worker is executing or waiting to be scheduled. So
ondemand_object_worker() may be called after the info and object and even
the cache have been freed and trigger use-after-free. So use
cancel_work_sync() in cachefiles_ondemand_clean_object() to cancel the
reopen worker or wait for it to finish. Since it makes no sense to wait
for the daemon to complete the reopen request, to avoid this pointless
operation blocking cancel_work_sync(), Patch 1 avoids request generation
by the DROPPING state when the request has not been sent, and Patch 2
flushes the requests of the current object before cancel_work_sync().
Patch 8: Cyclic allocation of msg_id to avoid msg_id reuse misleading
the daemon to cause hung.
Patch 9: Hold xas_lock during polling to avoid dereferencing reqs causing
use-after-free. This issue was triggered frequently in our tests, and we
found that anolis 5.10 had fixed it. So to avoid failing the test, this
patch is pushed upstream as well.

netfs, fscache: export fscache_put_volume() and add
fscache_try_get_volume()
cachefiles: fix slab-use-after-free in fscache_withdraw_volume()

At this time, conntrack either returns NF_ACCEPT or NF_DROP.
To improve debuging it would be nice to be able to replace NF_DROP
verdict with NF_DROP_REASON() helper,
This helper releases the skb instantly (so drop_monitor can pinpoint

Serge Semin <fancer says:
====================
net: pcs: xpcs: Add memory-mapped device support
The main goal of this series is to extend the DW XPCS device support in
the kernel. Particularly the patchset adds a support of the DW XPCS
device with the MCI/APB3 IO interface registered as a platform device. In
order to have them utilized by the DW XPCS core the fwnode-based DW XPCS
descriptor creation procedure has been introduced. Finally the STMMAC
driver has been altered to support the DW XPCS passed via the 'pcs-handle'
property.
Note the series has been significantly re-developed since v1. So I even
had to change the subject. Anyway I've done my best to take all the noted
into account.
The series traditionally starts with a set of the preparation patches.
First one just moves the generic DW XPCS IDs macros from the internal
header file to the external one where some other IDs also reside. Second
patch splits up the xpcs_create() method to a set of the coherent
sub-functions for the sake of the further easier updates and to have it
looking less complicated. The goal of the next three patches is to extend
the DW XPCS ID management code by defining a new dw_xpcs_info structure
with both PCS and PMA IDs.
The next two patches provide the DW XPCS device DT-bindings and the
respective platform-device driver for the memory-mapped DW XPCS devices.
Besides the later patch makes use of the introduced dw_xpcs_info structure
to pre-define the DW XPCS IDs based on the platform-device compatible
string. Thus if there is no way to auto-identify the XPCS device
capabilities it can be done based on the custom device IDs passed via the
MDIO-device platform data.
Final DW XPCS driver change is about adding a new method of the DW XPCS
descriptor creation. The xpcs_create_fwnode() function has been introduced
with the same semantics as a similar method recently added to the Lynx PCS
driver. It's supposed to be called with the fwnode pointing to the DW XPCS
device node, for which the XPCS descriptor will be created.
The series is terminated with two STMMAC driver patches. The former one
simplifies the DW XPCS descriptor registration procedure by dropping the
MDIO-bus scanning and creating the descriptor for the particular device
address. The later patch alters the STMMAC PCS setup method so one would
support the DW XPCS specified via the "pcs-handle" property.
That's it for now. Thanks for review in advance. Any tests are very
welcome. After this series is merged in, I'll submit another one which
adds the generic 10GBase-R and 10GBase-X interfaces support to the STMMAC
and DW XPCS driver with the proper CSRs re-initialization, PMA
initialization and reference clock selection as it's described in the
Synopsys DW XPCS HW manual.

Recently the DW XPCS DT-bindings have been introduced and the DW XPCS
driver has been altered to support the DW XPCS registered as a platform
device. In order to have the DW XPCS DT-device accessed from the STMMAC
driver let's alter the STMMAC PCS-setup procedure to support the
"pcs-handle" property containing the phandle reference to the DW XPCS
device DT-node. The respective fwnode will be then passed to the
xpcs_create_fwnode() function which in its turn will create the DW XPCS
descriptor utilized in the main driver for the PCS-related setups.

Currently the only STMMAC platform driver using the DW XPCS code is the
Intel mGBE device driver. (It can be determined by finding all the drivers
having the stmmac_mdio_bus_data::has_xpcs flag set.) At the same time the
low-level platform driver masks out the DW XPCS MDIO-address from being
auto-detected as PHY by the MDIO subsystem core. Seeing the PCS MDIO ID is
known the procedure of the DW XPCS device creation can be simplified by
dropping the loop over all the MDIO IDs. From now the DW XPCS device
descriptor will be created for the MDIO-bus address pre-defined by the
platform drivers via the stmmac_mdio_bus_data::pcs_mask field.
Note besides this shall speed up a bit the Intel mGBE probing.

It's now possible to have the DW XPCS device defined as a standard
platform device for instance in the platform DT-file. Although that
functionality is useless unless there is a way to have the device found by
the client drivers (STMMAC/DW *MAC, NXP SJA1105 Eth Switch, etc). Provide
such ability by means of the xpcs_create_fwnode() method. It needs to be
called with the device DW XPCS fwnode instance passed. That node will be
then used to find the MDIO-device instance in order to create the DW XPCS
descriptor.
Note the method semantics and name is similar to what has been recently
introduced in the Lynx PCS driver.

Synopsys DesignWare XPCS IP-core can be synthesized with the device CSRs
being accessible over the MCI or APB3 interface instead of the MDIO bus
(see the CSR_INTERFACE HDL parameter). Thus all the PCS registers can be
just memory mapped and be a subject of the standard MMIO operations of
course taking into account the peculiarities of the Clause C45 CSRs
mapping. From that perspective the DW XPCS devices would look as just
normal platform devices for the kernel.
On the other hand in order to have the DW XPCS devices handled by the
pcs-xpcs.c driver they need to be registered in the framework of the
MDIO-subsystem. So the suggested change is about providing a DW XPCS
platform device driver registering a virtual MDIO-bus with a single
MDIO-device representing the DW XPCS device.
DW XPCS platform device is supposed to be described by the respective
compatible string "snps,dw-xpcs" (or with the PMA-specific compatible
string), CSRs memory space and optional peripheral bus and reference clock
sources. Depending on the INDIRECT_ACCESS IP-core synthesize parameter the
memory-mapped reg-space can be represented as either directly or
indirectly mapped Clause 45 space. In the former case the particular
address is determined based on the MMD device and the registers offset (5
+ 16 bits all together) within the device reg-space. In the later case
there is only 8 lower address bits are utilized for the registers mapping
(255 CSRs). The upper bits are supposed to be written into the respective
viewport CSR in order to select the respective MMD sub-page.
Note, only the peripheral bus clock source is requested in the platform
device probe procedure. The core and pad clocks handling has been
implemented in the framework of the xpcs_create() method intentionally
since the clocks-related setups are supposed to be performed later, during
the DW XPCS main configuration procedures. (For instance they will be
required for the DW Gen5 10G PMA configuration.)

Synopsys DesignWare XPCS IP-core is a Physical Coding Sublayer (PCS) layer
providing an interface between the Media Access Control (MAC) and Physical
Medium Attachment Sublayer (PMA) through a Media independent interface.
From software point of view it exposes IEEE std. Clause 45 CSR space and
can be accessible either by MDIO or MCI/APB3 bus interfaces. In the former
case the PCS device is supposed to be defined under the respective MDIO
bus DT-node. In the later case the DW xPCS will be just a normal IO
memory-mapped device.
Besides of that DW XPCS DT-nodes can have an interrupt signal and clock
source properties specified. The former one indicates the Clause 73/37
auto-negotiation events like: negotiation page received, AN is completed
or incompatible link partner. The clock DT-properties can describe up to
three clock sources: peripheral bus clock source, internal reference clock
and the externally connected reference clock.
Finally the DW XPCS IP-core can be optionally synthesized with a
vendor-specific interface connected to the Synopsys PMA (also called
DesignWare Consumer/Enterprise PHY). Alas that isn't auto-detectable in a
portable way. So if the DW XPCS device has the respective PMA attached
then it should be reflected in the DT-node compatible string so the driver
would be aware of the PMA-specific device capabilities (mainly connected
with CSRs available for the fine-tunings).

The being introduced structure will preserve the PCS and PMA IDs retrieved
from the respective DW XPCS MMDs or potentially pre-defined by the client
drivers. (The later change will be introduced later in the framework of
the commit adding the memory-mapped DW XPCS devices support.)
The structure fields are filled in in the xpcs_get_id() function, which
used to be responsible for the PCS Device ID getting only. Besides of the
PCS ID the method now fetches the PMA/PMD IDs too from MMD 1, which used
to be done in xpcs_dev_flag(). The retrieved PMA ID will be from now
utilized for the PMA-specific tweaks like it was introduced for the
Wangxun TxGBE PCS in the commit f629acc6f210 ("net: pcs: xpcs: support to
switch mode for Wangxun NICs").
Note 1. The xpcs_get_id() error-handling semantics has been changed. From
now the error number will be returned from the function. There is no point
in the next IOs or saving 0xffs and then looping over the actual device
IDs if device couldn't be reached. -ENODEV will be returned if the very
first IO operation failed thus indicating that no device could be found.
Note 2. The PCS and PMA IDs macros have been converted to enum'es. The
enum'es will be populated later in another commit with the virtual IDs
identifying the DW XPCS devices which have some platform-specifics, but
have been synthesized with the default PCS/PMA ID.

As an initial preparation before adding the fwnode-based DW XPCS device
support let's split the xpcs_create() function code up to a set of the
small sub-functions. Thus the xpcs_create() implementation will get to
look simpler and turn to be more coherent. Further updates will just touch
the new sub-functions a bit: add platform-specific device info, add the
reference clock getting and enabling.
The xpcs_create() method will now contain the next static methods calls:
xpcs_create_data() - create the DW XPCS device descriptor, pre-initialize
it' fields and increase the mdio device refcount-er;
xpcs_init_id() - find XPCS ID instance and save it in the device
descriptor;
xpcs_init_iface() - find MAC/PCS interface descriptor and perform
basic initialization specific to it: soft-reset, disable polling.
The update doesn't imply any semantic change but merely makes the code
looking simpler and more ready for adding new features support.
Note the xpcs_destroy() has been moved to being defined below the
xpcs_create_mdiodev() function as the driver now implies having the
protagonist-then-antagonist functions definition order.

One of the next commits will alter the DW XPCS driver to support setting a
custom device ID for the particular MDIO-device detected on the platform.
The generic DW XPCS ID can be used as a custom ID as well in case if the
DW XPCS-device was erroneously synthesized with no or some undefined ID.
In addition to that having all supported DW XPCS device IDs defined in a
single place will improve the code maintainability and readability.
Note while at it rename the macros to being shorter and looking alike to

The SCSI disk message "Starting disk" to signal resuming of a suspended

in this message being printed twice when resuming from e.g. autosuspend:

$ echo auto > /sys/block/sda/device/power/control

Fix this double print by removing the call to sd_printk() from sd_resume()
and moving the call to sd_printk() in sd_resume_common() earlier in the
function, before the check using sd_do_start_stop(). Doing so, the message
is printed once regardless if sd_resume_common() actually executes
sd_start_stop_device() (i.e. SCSI device case) or not (libsas and libata

In rtw89_sta_info_get_iter() 'status->he_gi' is compared to array size.
But then 'rate->he_gi' is used as array index instead of 'status->he_gi'.
This can lead to go beyond array boundaries in case of 'rate->he_gi' is

Right now it's possible to hit NULL pointer dereference in
rtw_rx_fill_rx_status on hw object and/or its fields because
initialization routine can start getting USB replies before
rtw_dev is fully setup.
The stack trace looks like this:
rtw_rx_fill_rx_status
rtw8821c_query_rx_desc
rtw_usb_rx_handler
...
queue_work
rtw_usb_read_port_complete
...
usb_submit_urb
rtw_usb_rx_resubmit
rtw_usb_init_rx
rtw_usb_probe
So while we do the async stuff rtw_usb_probe continues and calls
rtw_register_hw, which does all kinds of initialization (e.g.
via ieee80211_register_hw) that rtw_rx_fill_rx_status relies on.
Fix this by moving the first usb_submit_urb after everything
is set up.
For me, this bug manifested as:
[ 8.893177] rtw_8821cu 1-1:1.2: band wrong, packet dropped
[ 8.910904] rtw_8821cu 1-1:1.2: hw->conf.chandef.chan NULL in rtw_rx_fill_rx_status
because I'm using Larry's backport of rtw88 driver with the NULL
checks in rtw_rx_fill_rx_status.

Commit 31e0aa99dc02 ("ethtool: Veto some operations during firmware flashing process")
added a flag module_fw_flash_in_progress to struct net_device. As
this is ethtool related state, move it to the recently created
struct ethtool_netdev_state, accessed via the 'ethtool' member of
struct net_device.
