Since "dev_search_path" can technically be as large as PATH_MAX,
there was a risk of truncation when copying it and a second string
into "full_path" since it was also PATH_MAX sized. The W=1 builds were
reporting this warning:
drivers/block/rnbd/rnbd-srv.c: In function 'process_msg_open.isra':
drivers/block/rnbd/rnbd-srv.c:616:51: warning: '%s' directive output may be truncated writing up to 254 bytes into a region of size between 0 and 4095 [-Wformat-truncation=]
616 | snprintf(full_path, PATH_MAX, "%s/%s",

In function 'rnbd_srv_get_full_path',
inlined from 'process_msg_open.isra' at drivers/block/rnbd/rnbd-srv.c:721:14: drivers/block/rnbd/rnbd-srv.c:616:17: note: 'snprintf' output between 2 and 4351 bytes into a destination of size 4096
616 | snprintf(full_path, PATH_MAX, "%s/%s",

617 | dev_search_path, dev_name);

To fix this, unconditionally check for truncation (as was already done
for the case where "%SESSNAME%" was present).

Currently rcu is used to protect iterating rdev from submit_flushes():
submit_flushes remove_and_add_spares
synchronize_rcu
pers->hot_remove_disk()
rcu_read_lock()
rdev_for_each_rcu
if (rdev->raid_disk >= 0)
rdev->radi_disk = -1;
atomic_inc(&rdev->nr_pending)
rcu_read_unlock()
bi = bio_alloc_bioset()
bi->bi_end_io = md_end_flush
bi->private = rdev
submit_bio
// issue io for removed rdev
Fix this problem by grabbing 'acive_io' before iterating rdev, make sure
that remove_and_add_spares() won't concurrent with submit_flushes().

Because it's safe to accees rdev from conf:
- If any spinlock is held, because synchronize_rcu() from
md_kick_rdev_from_array() will prevent 'rdev' to be freed until
spinlock is released;
- If there is normal IO inflight, because mddev_suspend() will prevent
rdev to be added or removed from array;
And these will cover all the scenarios in md-multipath.

rcu is not used correctly here, because synchronize_rcu() is called
before replacing old value, for example:
remove_and_add_spares // other path
synchronize_rcu
// called before replacing old value
set_bit(RemoveSynchronized)
rcu_read_lock()
rdev = conf->mirros[].rdev
pers->hot_remove_disk
conf->mirros[].rdev = NULL;
if (!test_bit(RemoveSynchronized))
synchronize_rcu
/*
* won't be called, and won't wait
* for concurrent readers to be done.
*/
// access rdev after remove_and_add_spares()
rcu_read_unlock()
Fortunately, there is a separate rcu protection to prevent such rdev
to be freed:
md_kick_rdev_from_array //other path
rcu_read_lock()
rdev = conf->mirros[].rdev
list_del_rcu(&rdev->same_set)
rcu_read_unlock()
/*
* rdev can be removed from conf, but
* rdev won't be freed.
*/
synchronize_rcu()
free rdev
Hence remove this useless flag and prepare to remove rcu protection to
access rdev from 'conf'.

If a VF tries to add unsupported cloud filter through virtchnl
then i40e_add_del_cloud_filter(_big_buf) returns -ENOTSUPP but
this error code is stored in 'ret' instead of 'aq_ret' that
is used as error code sent back to VF. In this scenario where
one of the mentioned functions fails the value of 'aq_ret'
is zero so the VF will incorrectly receive a 'success'.
Use 'aq_ret' to store return value and remove 'ret' local
variable. Additionally fix the issue when filter allocation
fails, in this case no notification is sent back to the VF.

The driver calls ice_ptp_cfg_timestamp() during ice_ptp_prepare_for_reset()
to disable timestamping while the device is resetting. This operation
destroys the user requested configuration. While the driver does call
ice_ptp_cfg_timestamp in ice_rebuild() to restore some hardware settings
after a reset, it unconditionally passes true or false, resulting in
failure to restore previous user space configuration.
This results in a device reset forcibly disabling timestamp configuration
regardless of current user settings.
This was not detected previously due to a quirk of the LinuxPTP ptp4l
application. If ptp4l detects a missing timestamp, it enters a fault state
and performs recovery logic which includes executing SIOCSHWTSTAMP again,
restoring the now accidentally cleared configuration.
Not every application does this, and for these applications, timestamps
will mysteriously stop after a PF reset, without being restored until an
application restart.
Fix this by replacing ice_ptp_cfg_timestamp() with two new functions:
1) ice_ptp_disable_timestamp_mode() which unconditionally disables the
timestamping logic in ice_ptp_prepare_for_reset() and ice_ptp_release()
2) ice_ptp_restore_timestamp_mode() which calls
ice_ptp_restore_tx_interrupt() to restore Tx timestamping configuration,
calls ice_set_rx_tstamp() to restore Rx timestamping configuration, and
issues an immediate TSYN_TX interrupt to ensure that timestamps which
may have occurred during the device reset get processed.
Modify the ice_ptp_set_timestamp_mode to directly save the user
configuration and then call ice_ptp_restore_timestamp_mode. This way, reset
no longer destroys the saved user configuration.
This obsoletes the ice_set_tx_tstamp() function which can now be safely
removed.
With this change, all devices should now restore Tx and Rx timestamping
functionality correctly after a PF reset without application intervention.

Commit d938a8cca88a ("ice: Auxbus devices & driver for E822 TS") modified
how Tx timestamps are handled for E822 devices. On these devices, only the
clock owner handles reading the Tx timestamp data from firmware. To do
this, the PFINT_TSYN_MSK register is modified from the default value to one
which enables reacting to a Tx timestamp on all PHY ports.
The driver currently programs PFINT_TSYN_MSK in different places depending
on whether the port is the clock owner or not. For the clock owner, the
PFINT_TSYN_MSK value is programmed during ice_ptp_init_owner just before
calling ice_ptp_tx_ena_intr to program the PHY ports.
For the non-clock owner ports, the PFINT_TSYN_MSK is programmed during
ice_ptp_init_port.
If a large enough device reset occurs, the PFINT_TSYN_MSK register will be
reset to the default value in which only the PHY associated directly with
the PF will cause the Tx timestamp interrupt to trigger.
The driver lacks logic to reprogram the PFINT_TSYN_MSK register after a
device reset. For the E822 device, this results in the PF no longer
responding to interrupts for other ports. This results in failure to
deliver Tx timestamps to user space applications.
Rename ice_ptp_configure_tx_tstamp to ice_ptp_cfg_tx_interrupt, and unify
the logic for programming PFINT_TSYN_MSK and PFINT_OICR_ENA into one place.
This function will program both registers according to the combination of
user configuration and device requirements.
This ensures that PFINT_TSYN_MSK is always restored when we configure the
Tx timestamp interrupt.

Before performing a Tx timestamp in ice_stamp(), the driver checks a ptp_tx
ring variable to see if timestamping is enabled on that ring. This value is
set for all rings whenever userspace configures Tx timestamping.
Ostensibly this was done to avoid wasting cycles checking other fields when
timestamping has not been enabled. However, for Tx timestamps we already
get an individual per-SKB flag indicating whether userspace wants to
request a timestamp on that packet. We do not gain much by also having
a separate flag to check for whether timestamping was enabled.
In fact, the driver currently fails to restore the field after a PF reset.
Because of this, if a PF reset occurs, timestamps will be disabled.
Since this flag doesn't add value in the hotpath, remove it and always
provide a timestamp if the SKB flag has been set.
A following change will fix the reset path to properly restore user
timestamping configuration completely.
This went unnoticed for some time because one of the most common
applications using Tx timestamps, ptp4l, will reconfigure the socket as
part of its fault recovery logic.

completions until the specified time (1ms) is met and then poll them.
However, there exists a tiny gap which leads to a race between
resetting and checking the tx_activate flag. Due to this the tx

In this case on v0 the page_pool stats overwrites tx xdp_stats for queue 1.

queue than its PF
It is possible to add a ntuple rule which would like to direct packet to
a VF whose number of queues are greater/less than its PF's queue numbers.
For example a PF can have 2 Rx queues but a VF created on that PF can have
8 Rx queues. As of today, ntuple rule will reject rule because it is
checking the requested queue number against PF's number of Rx queues.
As a part of this fix if the action of a ntuple rule is to move a packet
to a VF's queue then the check is removed. Also, a debug information is
printed to aware user that it is user's responsibility to cross check if
the requested queue number on that VF is a valid one.

When CONFIG_NVME_KEYRING is enabled as a loadable module, but the TCP
host code is built-in, it fails to link:
arm-linux-gnueabi-ld: drivers/nvme/host/tcp.o: in function `nvme_tcp_setup_ctrl':
tcp.c:(.text+0x1940): undefined reference to `nvme_tls_psk_default'
The problem is that the compile-time conditionals are inconsistent here,
using a mix of #ifdef CONFIG_NVME_TCP_TLS, IS_ENABLED(CONFIG_NVME_TCP_TLS)
and IS_ENABLED(CONFIG_NVME_KEYRING) checks, with CONFIG_NVME_KEYRING
controlling whether the implementation is actually built.
Change it to use IS_ENABLED(CONFIG_NVME_KEYRING) checks consistently,
which should help readability and make it less error-prone. Combining
it with the check for the ctrl->opts->tls flag lets the compiler drop
all the TLS code in configurations without this feature, which also
helps runtime behavior in addition to avoiding the link failure.
To make it possible for the compiler to build the dead code, both
the tls_handshake_timeout variable and the TLS specific members
of nvme_tcp_queue need to be moved out of the #ifdef block as well,
but at least the former of these gets optimized out again.

When the NVME target code is built-in but its TCP frontend is a loadable

configfs.c:(.text+0x100a211): undefined reference to `nvme_keyring_id'
The problem is that CONFIG_NVME_TARGET_TCP_TLS is a 'bool' symbol that
depends on the tristate CONFIG_NVME_TARGET_TCP, so any 'select' from
it inherits the state of the tristate symbol rather than the intended
CONFIG_NVME_TARGET one that contains the actual call.
The same thing is true for CONFIG_KEYS, which itself is required for
NVME_KEYRING.

Use the IRQF_NO_AUTOEN irq flag when requesting the wakeup interrupts
instead of setting it separately.
No functional change intended.

The Qualcomm glue driver is overriding the interrupt trigger types
defined by firmware when requesting the wakeup interrupts during probe.
This can lead to a failure to map the DP/DM wakeup interrupts after a
probe deferral as the firmware defined trigger types do not match the
type used for the initial mapping:
irq: type mismatch, failed to map hwirq-14 for interrupt-controller@b220000!
irq: type mismatch, failed to map hwirq-15 for interrupt-controller@b220000!
Fix this by not overriding the firmware provided trigger types when
requesting the wakeup interrupts.

Add support for the Microchip USB5744 USB3.0 and USB2.0 Hub.
The Microchip USB5744 supports two power supplies, one for 1V2 and one
for 3V3. According to the datasheet there is no need for a delay between
power on and reset, so this value is set to 0.
