4d159f7884 ice: Do not use WQ_MEM_RECLAIM flag for workqueue
When both ice and the irdma driver are loaded, a warning in
check_flush_dependency is being triggered. This is due to ice driver
workqueue being allocated with the WQ_MEM_RECLAIM flag and the irdma one
is not.

According to kernel documentation, this flag should be set if the
workqueue will be involved in the kernel's memory reclamation flow.
Since it is not, there is no need for the ice driver's WQ to have this
flag set so remove it.

Example trace:

d7d94b2612 net: microchip: sparx5: fix PTP init/deinit not checking all ports
Check all ports instead of just port_count ports. PTP init was only
checking ports 0 to port_count. If the hardware ports are not mapped
starting from 0 then they would be missed, e.g. if only ports 20-30 were
mapped it would attempt to init ports 0-10, resulting in NULL pointers
when attempting to timestamp. Now it will init all mapped ports.

03702d4d29 uapi: add missing ip/ipv6 header dependencies for linux/stddef.h
Since commit 58e0be1ef6 ("net: use struct_group to copy ip/ipv6
header addresses"), ip and ipv6 headers started to use the __struct_group
definition, which is defined at include/uapi/linux/stddef.h. However,
linux/stddef.h isn't explicitly included in include/uapi/linux/{ip,ipv6}.h,
which breaks build of xskxceiver bpf selftest if you install the uapi
headers in the system:

$ make V=1 xskxceiver -C tools/testing/selftests/bpf
...
make: Entering directory '(...)/tools/testing/selftests/bpf'
gcc -g -O0 -rdynamic -Wall -Werror (...)
In file included from xskxceiver.c:79:

  103 |         __struct_group(/* no tag */, addrs, /* no attrs */,
      |         ^~~~~~~~~~~~~~
...

Include the missing <linux/stddef.h> dependency in ip.h and do the
same for the ipv6.h header.

c1d2ecdf5e neigh: make sure used and confirmed times are valid
Entries can linger in cache without timer for days, thanks to
the gc_thresh1 limit. As result, without traffic, the confirmed
time can be outdated and to appear to be in the future. Later,
on traffic, NUD_STALE entries can switch to NUD_DELAY and start
the timer which can see the invalid confirmed time and wrongly
switch to NUD_REACHABLE state instead of NUD_PROBE. As result,
timer is set many days in the future. This is more visible on
32-bit platforms, with higher HZ value.

Why this is a problem? While we expect unused entries to expire,
such entries stay in REACHABLE state for too long, locked in
cache. They are not expired normally, only when cache is full.

Problem and the wrong state change reported by Zhang Changzhong:

172.16.1.18 dev bond0 lladdr 0a:0e:0f:01:12:01 ref 1 used 350521/15994171/350520 probes 4 REACHABLE

350520 seconds have elapsed since this entry was last updated, but it is
still in the REACHABLE state (base_reachable_time_ms is 30000),
preventing lladdr from being updated through probe.

Fix it by ensuring timer is started with valid used/confirmed
times. Considering the valid time range is LONG_MAX jiffies,
we try not to go too much in the past while we are in
DELAY/PROBE state. There are also places that need
used/updated times to be validated while timer is not running.

69ff53e4a4 net: phy: meson-gxl: use MMD access dummy stubs for GXL, internal PHY
Jerome provided the information that also the GXL internal PHY doesn't
support MMD register access and EEE. MMD reads return 0xffff, what
results in e.g. completely wrong ethtool --show-eee output.
Therefore use the MMD dummy stubs.

c9011b028e net: macb: Perform zynqmp dynamic configuration only for SGMII interface
In zynqmp platforms where firmware supports dynamic SGMII configuration
but has other non-SGMII ethernet devices, it fails them with no packets
received at the RX interface.

To fix this behaviour perform SGMII dynamic configuration only
for the SGMII phy interface.

cbe83191d4 bonding: fix error checking in bond_debug_reregister()
Since commit ff9fb72bc0 ("debugfs: return error values,
not NULL") changed return value of debugfs_rename() in
error cases from %NULL to %ERR_PTR(-ERROR), we should
also check error values instead of NULL.

ce93fdb5f2 net: phylink: move phy_device_free() to correctly release phy device
After calling fwnode_phy_find_device(), the phy device refcount is
incremented. Then, when the phy device is attached to a netdev with
phy_attach_direct(), the refcount is also incremented but only
decremented in the caller if phy_attach_direct() fails. Move
phy_device_free() before the "if" to always release it correctly.
Indeed, either phy_attach_direct() failed and we don't want to keep a
reference to the phydev or it succeeded and a reference has been taken
internally.

42c78a5b29 ARM: SoC fixes for 6.2, part 3
The majority of bugfixes is once more for the NXP i.MX platform,
 addressing issue with i.MX8M (UART, watchdog and ethernet) as well as
 imx8dxl power button and the USB modem on an imx7 board. The reason that
 i.MX always shows up here is obviously not that they are more buggy than
 the others, but they have the most boards and are good about getting
 fixes in quickly.
 
 The other DT fixes are for the Nuvoton wpcm450 flash controller and
 the i2c mux on an ASpeed board.
 
 Lastly, there are updates to the MAINTAINERS entries for Mediatek,
 AMD/Seattle and NXP SoCs, as well as a lone code fix for error
 handling in the allwinner "rsb" bus driver.

addfba11b3 s390 fixes for 6.2-rc7
- With CONFIG_VMAP_STACK enabled it is not possible to load the s390
   specific diag288_wdt watchdog module. Reason is that a pointer to a
   string is passed to an inline assembly; this string however is located on
   the stack, while the instruction within the inline assembly expects a
   physicial address. Fix this by copying the string to a kmalloc'ed buffer.
 
 - The diag288_wdt watchdog module does not indicate that it accesses memory
   from an inline assembly, which it does. Add "memory" to the clobber list
   to prevent the compiler from optimizing code incorrectly away.
 
 - Pass size of the uncompressed kernel image to __decompress() call.
   Otherwise the kernel image decompressor may corrupt/overwrite an
   initrd. This was reported to happen on s390 after commit 2aa14b1ab2
   ("zstd: import usptream v1.5.2").

7ff82416de net: mediatek: sgmii: ensure the SGMII PHY is powered down on configuration
The code expect the PHY to be in power down which is only true after reset.
Allow changes of the SGMII parameters more than once.

Only power down when reconfiguring to avoid bouncing the link when there's
no reason to - based on code from Russell King.

There are cases when the SGMII_PHYA_PWD register contains 0x9 which
prevents SGMII from working. The SGMII still shows link but no traffic
can flow. Writing 0x0 to the PHYA_PWD register fix the issue. 0x0 was
taken from a good working state of the SGMII interface.

can 2023-02-02

The first patch is by Ziyang Xuan and removes a errant WARN_ON_ONCE()
in the CAN J1939 protocol.

The next 3 patches are by Oliver Hartkopp. The first 2 target the CAN
ISO-TP protocol and fix the state machine with respect to signals and
a regression found by the syzbot.

The last patch is by me an missing assignment during the ethtool ring
configuration callback.

329c9cd769 selftests: net: udpgso_bench_tx: Cater for pending datagrams zerocopy benchmarking
The test tool can check that the zerocopy number of completions value is
valid taking into consideration the number of datagram send calls. This can
catch the system into a state where the datagrams are still in the system
(for example in a qdisk, waiting for the network interface to return a
completion notification, etc).

This change adds a retry logic of computing the number of completions up to
a configurable (via CLI) timeout (default: 2 seconds).

dafe93b9ee selftests: net: udpgso_bench: Fix racing bug between the rx/tx programs
"udpgro_bench.sh" invokes udpgso_bench_rx/udpgso_bench_tx programs
subsequently and while doing so, there is a chance that the rx one is not
ready to accept socket connections. This racing bug could fail the test
with at least one of the following:

./udpgso_bench_tx: connect: Connection refused
./udpgso_bench_tx: sendmsg: Connection refused
./udpgso_bench_tx: write: Connection refused

This change addresses this by making udpgro_bench.sh wait for the rx
program to be ready before firing off the tx one - up to a 10s timeout.

4f027cba82 can: isotp: split tx timer into transmission and timeout
The timer for the transmission of isotp PDUs formerly had two functions:
1. send two consecutive frames with a given time gap
2. monitor the timeouts for flow control frames and the echo frames

This led to larger txstate checks and potentially to a problem discovered
by syzbot which enabled the panic_on_warn feature while testing.

The former 'txtimer' function is split into 'txfrtimer' and 'txtimer'
to handle the two above functionalities with separate timer callbacks.

The two simplified timers now run in one-shot mode and make the state
transitions (especially with isotp_rcv_echo) better understandable.

3793301cba can: raw: fix CAN FD frame transmissions over CAN XL devices
A CAN XL device is always capable to process CAN FD frames. The former
check when sending CAN FD frames relied on the existence of a CAN FD
device and did not check for a CAN XL device that would be correct
too.

With this patch the CAN FD feature is enabled automatically when CAN
XL is switched on - and CAN FD cannot be switch off while CAN XL is
enabled.

This precondition also leads to a clean up and reduction of checks in
the hot path in raw_rcv() and raw_sendmsg(). Some conditions are
reordered to handle simple checks first.

d0553680f9 can: j1939: fix errant WARN_ON_ONCE in j1939_session_deactivate
The conclusion "j1939_session_deactivate() should be called with a
session ref-count of at least 2" is incorrect. In some concurrent
scenarios, j1939_session_deactivate can be called with the session
ref-count less than 2. But there is not any problem because it
will check the session active state before session putting in
j1939_session_deactivate_locked().

Here is the concurrent scenario of the problem reported by syzbot
and my reproduction log.

99f1c46011 hv_netvsc: Fix missed pagebuf entries in netvsc_dma_map/unmap()
netvsc_dma_map() and netvsc_dma_unmap() currently check the cp_partial
flag and adjust the page_count so that pagebuf entries for the RNDIS
portion of the message are skipped when it has already been copied into
a send buffer. But this adjustment has already been made by code in
netvsc_send(). The duplicate adjustment causes some pagebuf entries to
not be mapped. In a normal VM, this doesn't break anything because the
mapping doesn’t change the PFN. But in a Confidential VM,
dma_map_single() does bounce buffering and provides a different PFN.
Failing to do the mapping causes the wrong PFN to be passed to Hyper-V,
and various errors ensue.

Fix this by removing the duplicate adjustment in netvsc_dma_map() and
netvsc_dma_unmap().

Thomas Winter says:

====================
ip/ip6_gre: Fix GRE tunnels not generating IPv6 link local addresses

For our point-to-point GRE tunnels, they have IN6_ADDR_GEN_MODE_NONE
when they are created then we set IN6_ADDR_GEN_MODE_EUI64 when they
come up to generate the IPv6 link local address for the interface.
Recently we found that they were no longer generating IPv6 addresses.

Also, non-point-to-point tunnels were not generating any IPv6 link
local address and instead generating an IPv6 compat address,
breaking IPv6 communication on the tunnel.

These failures were caused by commit e5dd729460 and this patch set
aims to resolve these issues.

30e2291f61 ip/ip6_gre: Fix non-point-to-point tunnel not generating IPv6 link local address
We recently found that our non-point-to-point tunnels were not
generating any IPv6 link local address and instead generating an
IPv6 compat address, breaking IPv6 communication on the tunnel.

Previously, addrconf_gre_config always would call addrconf_addr_gen
and generate a EUI64 link local address for the tunnel.
Then commit e5dd729460 changed the code path so that add_v4_addrs
is called but this only generates a compat IPv6 address for
non-point-to-point tunnels.

I assume the compat address is specifically for SIT tunnels so
have kept that only for SIT - GRE tunnels now always generate link
local addresses.

23ca0c2c93 ip/ip6_gre: Fix changing addr gen mode not generating IPv6 link local address
For our point-to-point GRE tunnels, they have IN6_ADDR_GEN_MODE_NONE
when they are created then we set IN6_ADDR_GEN_MODE_EUI64 when they
come up to generate the IPv6 link local address for the interface.
Recently we found that they were no longer generating IPv6 addresses.
This issue would also have affected SIT tunnels.

Commit e5dd729460 changed the code path so that GRE tunnels
generate an IPv6 address based on the tunnel source address.
It also changed the code path so GRE tunnels don't call addrconf_addr_gen
in addrconf_dev_config which is called by addrconf_sysctl_addr_gen_mode
when the IN6_ADDR_GEN_MODE is changed.

This patch aims to fix this issue by moving the code in addrconf_notify
which calls the addr gen for GRE and SIT into a separate function
and calling it in the places that expect the IPv6 address to be
generated.

The previous addrconf_dev_config is renamed to addrconf_eth_config
since it only expected eth type interfaces and follows the
addrconf_gre/sit_config format.

A part of this changes means that the loopback address will be
attempted to be configured when changing addr_gen_mode for lo.
This should not be a problem because the address should exist anyway
and if does already exist then no error is produced.
