dpaa2_switch_acl_entry_remove()
The cmd_buff needs to be freed when error happened in

The greth_init_rings() function won't free the newly allocated skb when

When sending packets between nodes in netns, it calls tipc_lxc_xmit() for
peer node to receive the packets where tipc_sk_mcast_rcv()/tipc_sk_rcv()
might be called, and it's pretty much like in tipc_rcv().
Currently the local 'node rw lock' is held during calling tipc_lxc_xmit()
to protect the peer_net not being freed by another thread. However, when
receiving these packets, tipc_node_add_conn() might be called where the
peer 'node rw lock' is acquired. Then a dead lock warning is triggered by
lockdep detector, although it is not a real dead lock:

This patch avoids this warning by not holding the 'node rw lock' before
calling tipc_lxc_xmit(). As to protect the 'peer_net', rcu_read_lock()
should be enough, as in cleanup_net() when freeing the netns, it calls
synchronize_rcu() before the free is continued.
Also since tipc_lxc_xmit() is like the RX path in tipc_rcv(), it makes
sense to call it under rcu_read_lock(). Note that the right lock order
must be:
rcu_read_lock();
tipc_node_read_lock(n);
tipc_node_read_unlock(n);
tipc_lxc_xmit();
rcu_read_unlock();
instead of:
tipc_node_read_lock(n);
rcu_read_lock();
tipc_node_read_unlock(n);
tipc_lxc_xmit();
rcu_read_unlock();
and we have to call tipc_node_read_lock/unlock() twice in
tipc_node_xmit().

Ido Schimmel says:
====================
ipv4: Two small fixes for bugs in IPv4 routing code.
A variation of the second bug was reported by an FRR 5.0 (released
06/18) user as this version was setting a table ID of 0 for the
default VRF, unlike iproute2 and newer FRR versions.
The first bug was discovered while fixing the second.
Both bugs are not regressions (never worked) and are not critical
in my opinion, so the fixes can be applied to net-next, if desired.
No regressions in other tests:
# ./fib_tests.sh

Cited commit added the table ID to the FIB info structure, but did not
properly initialize it when table ID 0 is used. This can lead to a route
in the default VRF with a preferred source address not being flushed
when the address is deleted.
Consider the following example:
# ip address add dev dummy1 192.0.2.1/28
# ip address add dev dummy1 192.0.2.17/28
# ip route add 198.51.100.0/24 via 192.0.2.2 src 192.0.2.17 metric 100
# ip route add table 0 198.51.100.0/24 via 192.0.2.2 src 192.0.2.17 metric 200
# ip route show 198.51.100.0/24
198.51.100.0/24 via 192.0.2.2 dev dummy1 src 192.0.2.17 metric 100
198.51.100.0/24 via 192.0.2.2 dev dummy1 src 192.0.2.17 metric 200
Both routes are installed in the default VRF, but they are using two
different FIB info structures. One with a metric of 100 and table ID of
254 (main) and one with a metric of 200 and table ID of 0. Therefore,
when the preferred source address is deleted from the default VRF,
the second route is not flushed:
# ip address del dev dummy1 192.0.2.17/28
# ip route show 198.51.100.0/24
198.51.100.0/24 via 192.0.2.2 dev dummy1 src 192.0.2.17 metric 200
Fix by storing a table ID of 254 instead of 0 in the route configuration
structure.
Add a test case that fails before the fix:
# ./fib_tests.sh -t ipv4_del_addr

Cited commit added the table ID to the FIB info structure, but did not
prevent structures with different table IDs from being consolidated.
This can lead to routes being flushed from a VRF when an address is
deleted from a different VRF.

info. This is already done for FIB info structures backed by a nexthop

Prior to the Fixes: commit, the initialization code went through the
same fec_enet_set_coalesce() function as used by ethtool, and that
function correctly checks whether the current variant has support for
irq coalescing.
Now that the initialization code instead calls fec_enet_itr_coal_set()
directly, that call needs to be guarded by a check for the
FEC_QUIRK_HAS_COALESCE bit.

There is warning report about of_node refcount leak

of_node_get()/of_node_put() unbalanced - destroy cset entry:
attach overlay node /spi/soc@0/mdio@710700c0/ethernet@4
In of_mdiobus_register_device(), we increase fwnode refcount
by fwnode_handle_get() before associating the of_node with
mdio device, but it has never been decreased in normal path.
Since that, in mdio_device_release(), it needs to call
fwnode_handle_put() in addition instead of calling kfree()
directly.
After above, just calling mdio_device_free() in the error handle
path of of_mdiobus_register_device() is enough to keep the
refcount balanced.

After calling napi_complete_done(), the NAPIF_STATE_SCHED bit may be
cleared, and another CPU can start napi thread and access per-CQ variable,
cq->work_done. If the other thread (for example, from busy_poll) sets
it to a value >= budget, this thread will continue to run when it should
stop, and cause memory corruption and panic.
To fix this issue, save the per-CQ work_done variable in a local variable
before napi_complete_done(), so it won't be corrupted by a possible
concurrent thread after napi_complete_done().
Also, add a flag bit to advertise to the NIC firmware: the NAPI work_done
variable race is fixed, so the driver is able to reliably support features
like busy_poll.

A NAPI is setup for each network sring to poll data to kernel
The sring with source host is destroyed before live migration and
new sring with target host is setup after live migration.
The NAPI for the old sring is not deleted until setup new sring
with target host after migration. With busy_poll/busy_read enabled,
the NAPI can be polled before got deleted when resume VM.

Previously the xmit function could return -EBUSY without freeing, which
supposedly is interpreted as a drop. And was using kfree on successfully

sparx5_fdma_xmit and sparx5_inject returns error code, where -EBUSY
indicates TX_BUSY and any other error code indicates dropped.

otherwise it'll be dropped by application firmware.

On kernel 6.1-rcX, I have been getting the following dmesg error message
on every boot, resume from suspend and rfkill unblock of the Bluetooth
device:
Bluetooth: hci0: HCI_REQ-0xfcf0
After some investigation, it turned out to be caused by
commit dd50a864ffae ("Bluetooth: Delete unreferenced hci_request code")
which modified hci_req_add() in net/bluetooth/hci_request.c to always
print an error message when it is executed. In my case, the function was
executed by msft_set_filter_enable() in net/bluetooth/msft.c, which
provides support for Microsoft vendor opcodes.
As explained by Brian Gix, "the error gets logged because it is using a
deprecated (but still working) mechanism to issue HCI opcodes" [1]. So
this is just a debugging tool to show that a deprecated function is
executed. As such, it should not be included in the mainline kernel.
See for example
commit 771c035372a0 ("deprecate the '__deprecated' attribute warnings entirely and for good")
Additionally, this error message is cryptic and the user is not able to
do anything about it.

The rationale of showing this is that it's potentially critical
information to diagnose and find more CSR compatibility bugs in the
future and it will save a lot of headaches.
Given that clones come from a wide array of vendors (some are actually
Barrot, some are something else) and these numbers are what let us find
differences between actual and fake ones, it will be immensely helpful
to scour the Internet looking for this pattern and building an actual
database to find correlations and improve the checks.

A patch series by a Qualcomm engineer essentially removed my
quirk/workaround because they thought it was unnecessary.
It wasn't, and it broke everything again:
https://patchwork.kernel.org/project/netdevbpf/list/?series=661703&archive=both&state=*
He argues that the quirk is not necessary because the code should check
if the dongle says if it's supported or not. The problem is that for
these Chinese CSR clones they say that it would work:
