The kernel test robot reports that commit c42ff46f97c1 ("ocfs2: simplify

results in kernel warning messages like
sysctl table check failed: fs/ocfs2/nm Not a file
sysctl table check failed: fs/ocfs2/nm No proc_handler
sysctl table check failed: fs/ocfs2/nm bogus .mode 0555
and in fact this was already reported back in linux-next, but nobody
seems to have reacted to that report. Possibly that original report
only ever made it to the lkp list.
The problem seems to be that the simplification didn't actually go far
enough, and should have converted the whole directory path to the final
sysctl file, rather than just the two first components.
So take that last step.

Currently, the dwmac-sun8i's stmmaceth clk isn't disabled even if the
the device has been runtime suspended. The reason is the driver gets
the "stmmaceth" clk as tx_clk and enabling it during probe. But
there's no other usage of tx_clk except preparing and enabling, so
we can remove tx_clk and its usage then rely on the common routine
stmmac_probe_config_dt() to prepare and enable the stmmaceth clk
during driver initialization, and benefit from the runtime pm feature
after probed.

net: dsa: realtek: MDIO interface and RTL8367S,RTL8367RB-VB
The old realtek-smi driver was linking subdrivers into a single
realtek-smi.ko After this series, each subdriver will be an independent
module required by either realtek-smi (platform driver) or the new
realtek-mdio (mdio driver). Both interface drivers (SMI or MDIO) are
independent, and they might even work side-by-side, although it will be
difficult to find such device. The subdriver can be individually
selected but only at buildtime, saving some storage space for custom
embedded systems.
Existing realtek-smi devices continue to work untouched during the
tests. The realtek-smi was moved into a realtek subdirectory, but it
normally does not break things.
I couldn't identify a fixed relation between port numbers (0..9) and
external interfaces (0..2), and I'm not sure if it is fixed for each
chip version or a device configuration. Until there is more info about
it, there is a new port property "realtek,ext-int" that can inform the
external interface.
The rtl8365mb might now handle multiple CPU ports and extint ports not
used as CPU ports. RTL8367S has an SGMII external interface, but my test
device (TP-Link Archer C5v4) uses only the second RGMII interface. We
need a test device with more external ports to test these features.
The driver still cannot handle SGMII ports.
RTL8367RB-VB support was added using information from Frank Wunderlich
<frank-w@public-files.de> but I didn't test it myself.
The rtl8365mb was tested with a MDIO-connected RTL8367S (TP-Link Acher
C5v4) and a SMI-connected RTL8365MB-VC switch (Asus RT-AC88U)
The rtl8366rb subdriver was not tested with this patch series, but it
was only slightly touched. It would be nice to test it, especially in an
MDIO-connected switch.
Best,
Luiz

Trap door number is a 4-bit number divided in two regions (3 and 1-bit).
Both values were not masked properly. This bug does not affect supported
devices as they use up to port 7 (ext2). It would only be a problem if
the driver becomes compatible with 10-port switches like RTL8370MB and
RTL8310SR.

External interfaces can be configured, even if they are not CPU ports.
The first CPU port will also be the trap port (for receiving trapped
frames from the switch).
The CPU information was dropped from chip data as it was not used
outside setup. The only other place it was used is when it wrongly
checks for CPU port when it should check for extint.
The supported modes check now uses port type and not port usage.
As a byproduct, more than one CPU can be configured. although this
might not work well with DSA setups. Also, this driver is still only
blindly forwarding all traffic to CPU port(s).
This change was not tested in a device with multiple active external
interfaces ports.

Realtek's RTL8367S, a 5+2 port 10/100/1000M Ethernet switch.
It shares the same driver family (RTL8367C) with other models
as the RTL8365MB-VC. Its compatible string is "realtek,rtl8367s".
It was tested only with MDIO interface (realtek-mdio), although it might
work out-of-the-box with SMI interface (using realtek-smi).

"extport" 0, 1, 2 was used to reference external ports id (ext0, ext1,
ext2). Meanwhile, port 0..9 is used as switch ports, including external
ports. "extport" was renamed to extint to make it clear it does not mean
the port number but the external interface number id.
The macros that map extint numbers to registers addresses now use inline
ifs instead of binary arithmetic.
Realtek uses in docs and drivers EXT_PORT0 (GMAC1) and EXT_PORT1
(GMAC2), with EXT_PORT0 being converted to ext_id == 1 and so on. It
might introduce some confusing while reading datasheets but it will not
be exposed to users.
"extint" was hardcoded to 1. However, some chips have multiple external
interfaces. It's not right to assume the CPU port uses extint 1 nor that
all extint are CPU ports. Now it came from a map between port number and
external interface id number.
This patch still does not allow multiple CPU ports nor extint as a non
CPU port.

If we dereference ax25_dev after we call kfree(ax25_dev) in
ax25_dev_device_down(), it will lead to concurrency UAF bugs.
There are eight syscall functions suffer from UAF bugs, include
ax25_bind(), ax25_release(), ax25_connect(), ax25_ioctl(),
ax25_getname(), ax25_sendmsg(), ax25_getsockopt() and
ax25_info_show().
One of the concurrency UAF can be shown as below:
(USE) | (FREE)
| ax25_device_event
| ax25_dev_device_down
ax25_bind | ...
... | kfree(ax25_dev)
ax25_fillin_cb() | ...
ax25_fillin_cb_from_dev() |
... |
The root cause of UAF bugs is that kfree(ax25_dev) in
ax25_dev_device_down() is not protected by any locks.
When ax25_dev, which there are still pointers point to,
is released, the concurrency UAF bug will happen.
This patch introduces refcount into ax25_dev in order to
guarantee that there are no pointers point to it when ax25_dev
is released.

The previous commit 1ade48d0c27d ("ax25: NPD bug when detaching
AX25 device") introduce lock_sock() into ax25_kill_by_device to
prevent NPD bug. But the concurrency NPD or UAF bug will occur,
when lock_sock() or release_sock() dereferences the ax25_cb->sock.
The NULL pointer dereference bug can be shown as below:
ax25_kill_by_device() | ax25_release()
| ax25_destroy_socket()
| ax25_cb_del()
... | ...
| ax25->sk=NULL;
lock_sock(s->sk); //(1) |
s->ax25_dev = NULL; | ...
release_sock(s->sk); //(2) |
... |
The root cause is that the sock is set to null before dereference
site (1) or (2). Therefore, this patch extracts the ax25_cb->sock
in advance, and uses ax25_list_lock to protect it, which can synchronize
with ax25_cb_del() and ensure the value of sock is not null before
dereference sites.
The concurrency UAF bug can be shown as below:
ax25_kill_by_device() | ax25_release()
| ax25_destroy_socket()
... | ...
| sock_put(sk); //FREE
lock_sock(s->sk); //(1) |
s->ax25_dev = NULL; | ...
release_sock(s->sk); //(2) |
... |
The root cause is that the sock is released before dereference
site (1) or (2). Therefore, this patch uses sock_hold() to increase
the refcount of sock and uses ax25_list_lock to protect it, which
can synchronize with ax25_cb_del() in ax25_destroy_socket() and
ensure the sock wil not be released before dereference sites.

ethtool: add header/data split indication
TCP ZC Rx requires data to be placed neatly into pages, separate
from the networking headers. This is not supported by most devices
so to make deployment easy this set adds a way for the driver to
report support for this feature thru ethtool.
The larger scope of configuring splitting headers and data, or DMA
scatter seems dauntingly broad, so this set focuses specifically
on the question "is this device usable with TCP ZC Rx?".
The aim is to avoid a litany of conditions on HW platforms, features,
and firmware versions in orchestration systems when the drivers can
easily tell their SG config.

For applications running on a mix of platforms it's useful
to have a clear indication whether host's NIC supports the
geometry requirements of TCP zero-copy. TCP zero-copy Rx
requires data to be neatly placed into memory pages.
Most NICs can't do that.
This patch is adding GET support only, since the NICs
I work with either always have the feature enabled or
enable it whenever MTU is set to jumbo. In other words
I don't need SET. But adding set should be trivial.
(The only note on SET is that we will likely want
the setting to be "sticky" and use 0 / `unknown`
to reset it back to driver default.)

o The server has not recorded an unconfirmed { v, x, c, *, * } and
has recorded a confirmed { v, x, c, *, s }. If the principals of
the record and of SETCLIENTID_CONFIRM do not match, the server
returns NFS4ERR_CLID_INUSE without removing any relevant leased
client state, and without changing recorded callback and
callback_ident values for client { x }.
The current code intends to do what the spec describes above but
it forgot to set 'old' to NULL resulting to the confirmed client
to be expired.
