DT files use the mac-mode property. Therefore, mac_interface already

Kuniyuki reports that the assert for netdev lock fires when
there are netdev event listeners (otherwise we skip the netlink

Correct the locking when coming from the notifier.
The NETDEV_XDP_FEAT_CHANGE notifier is already fully locked,
it's the documentation that's incorrect.

The new GCC 15 warning -Wunterminated-string-initialization reports:
In file included from drivers/net/ethernet/mellanox/mlx5/core/en.h:55,
from drivers/net/ethernet/mellanox/mlx5/core/en_stats.c:34:
drivers/net/ethernet/mellanox/mlx5/core/en_stats.h:57:46: warning: initializer-string for array of 'char' truncates NUL terminator but destination lacks 'nonstring' attribute (33 chars into 32 available) [-Wunterminated-string-initialization]

drivers/net/ethernet/mellanox/mlx5/core/en_stats.c:2279:11: note: in expansion of macro 'MLX5E_DECLARE_PTP_RQ_STAT'
2279 | { MLX5E_DECLARE_PTP_RQ_STAT(struct mlx5e_rq_stats, csum_complete_tail_slow) },
| ^~~~~~~~~~~~~~~~~~~~~~~~~
This stat string is being used in ethtool_sprintf(), so it must be a
valid NUL-terminated string. Currently the string lacks the final NUL
byte (as GCC warns), but by absolute luck, the next byte in memory is a
space (decimal 32) followed by a NUL. "format" is immediately followed
by little-endian size_t:
struct counter_desc {
char format[32]; /* 0 32 */
size_t offset; /* 32 8 */
};
The "offset" member is populated by the stats member offset:
#define MLX5E_DECLARE_PTP_RQ_STAT(type, fld) "ptp_rq%d_"#fld, offsetof(type, fld)
which for this struct mlx5e_rq_stats member, csum_complete_tail_slow, is
32, or space, and then the rest of the "offset" bytes are NULs.
struct mlx5e_rq_stats {
...
u64 csum_complete_tail_slow; /* 32 8 */
The use of vsnprintf(), within ethtool_sprintf(), reads past the end of
"format" and sees the format string as "ptp_rq%d_csum_complete_tail_slow ",
with %d getting resolved by MLX5E_PTP_CHANNEL_IX (value 0):
ethtool_sprintf(data, ptp_rq_stats_desc[i].format,
MLX5E_PTP_CHANNEL_IX);
With an output result of "ptp_rq0_csum_complete_tail_slow", which gets
precisely truncated to 31 characters with a trailing NUL.
So, instead of accidentally getting this correct due to the NUL bytes
at the end of the size_t that happens to follow the format string, just
make the string initializer 1 byte shorter by replacing "%d" with "0",
since MLX5E_PTP_CHANNEL_IX is already hard-coded. This results in no
initializer truncation and no need to call sprintf().

Many drivers populate the stats buffer using C-String based APIs (e.g.
ethtool_sprintf() and ethtool_puts()), usually when building up the
list of stats individually (i.e. with a for() loop). This, however,
requires that the source strings be populated in such a way as to have
a terminating NUL byte in the source.
Other drivers populate the stats buffer directly using one big memcpy()
of an entire array of strings. No NUL termination is needed here, as the
bytes are being directly passed through. Yet others will build up the
stats buffer individually, but also use memcpy(). This, too, does not
need NUL termination of the source strings.
However, there are cases where the strings that populate the
source stats strings are exactly ETH_GSTRING_LEN long, and GCC
15's -Wunterminated-string-initialization option complains that the
trailing NUL byte has been truncated. This situation is fine only if the
driver is using the memcpy() approach. If the C-String APIs are used,
the destination string name will have its final byte truncated by the
required trailing NUL byte applied by the C-string API.
For drivers that are already using memcpy() but have initializers that
truncate the NUL terminator, mark their source strings as __nonstring to
silence the GCC warnings.
For drivers that have initializers that truncate the NUL terminator and
are using the C-String APIs, switch to memcpy() to avoid destination
string truncation and mark their source strings as __nonstring to silence
the GCC warnings. (Also introduce ethtool_cpy() as a helper to make this
an easy replacement).

net: stmmac: sunxi cleanups
This series cleans up the sunxi (sun7i) code in two ways:
1. it converts to use the new set_clk_tx_rate() method, even though
we don't use clk_tx_i. In doing so, I reformat the function to
read better, but with no changes to the code.
2. convert from stmmac_dvr_probe() to stmmac_pltfr_probe(), and then
to its devm variant, which allows code simplification.

Using devm_stmmac_pltfr_probe() simplifies the probe function. This
will not only call plat_dat->init (sun7i_dwmac_init), but also
plat_dat->exit (sun7i_dwmac_exit) appropriately if stmmac_dvr_probe()
fails. This results in an overall simplification of the glue driver.

Rather than open-coding the calls to sun7i_gmac_init() and
sun7i_gmac_exit() in the probe function, use stmmac_pltfr_probe()
which will automatically call the plat_dat->init() and plat_dat->exit()
methods appropriately. This simplifies the code.

Mitigate double allocations in ioam6_iptunnel
Commit dce525185b ("net: ipv6: ioam6_iptunnel: mitigate 2-realloc
issue") fixed the double allocation issue in ioam6_iptunnel. However,
since commit 92191dd107 ("net: ipv6: fix dst ref loops in rpl, seg6
and ioam6 lwtunnels"), the fix was left incomplete. Because the cache is
now empty when the dst_entry is the same post transformation in order to
avoid a reference loop, the double reallocation is back for such cases
(e.g., inline mode) which are valid for IOAM. This patch provides a way
to detect such cases without having a reference loop in the cache, and
so to avoid the double reallocation issue for all cases again.

If the dst_entry is the same post transformation (which is a valid use
case for IOAM), we don't add it to the cache to avoid a reference loop.
Instead, we use a "fake" dst_entry and add it to the cache as a signal.
When we read the cache, we compare it with our "fake" dst_entry and
therefore detect if we're in the special case.

The ovpn-cli tool can be compiled and used as selftest for the ovpn
kernel module.
[NOTE: it depends on libmedtls for decoding base64-encoded keys]
ovpn-cli implements the netlink and RTNL APIs and can thus be integrated
in any script for more automated testing.
Along with the tool, a bunch of scripts are provided that perform basic
functionality tests by means of network namespaces.
These scripts take part to the kselftest automation.
The output of the scripts, which will appear in the kselftest
reports, is a list of steps performed by the scripts plus some
output coming from the execution of `ping`, `iperf` and `ovpn-cli`
itself.
In general it is useful only in case of failure, in order to
understand which step has failed and why.
Please note: since peer sockets are tied to the userspace
process that created them (i.e. exiting the process will result
in closing the socket), every run of ovpn-cli that created
one will go to background and enter pause(), waiting for the
signal which will allow it to terminate.
Termination is accomplished at the end of each script by
issuing a killall command.

IV wrap-around is cryptographically dangerous for a number of ciphers,
therefore kill the key and inform userspace (via netlink) should the
IV space go exhausted.
Userspace has two ways of deciding when the key has to be renewed before
exhausting the IV space:
1) time based approach:
after X seconds/minutes userspace generates a new key and sends it
to the kernel. This is based on guestimate and normally default
timer value works well.
2) packet count based approach:
after X packets/bytes userspace generates a new key and sends it to
the kernel. Userspace keeps track of the amount of traffic by
periodically polling GET_PEER and fetching the VPN/LINK stats.

specific peer needs to be looked up.
We may want to lookup a peer by:
1. its ID
2. its VPN destination IP
3. its transport IP/port couple
For each of the above, there is a specific routing table referencing all
peers for fast look up.
Case 2. is a bit special in the sense that an outgoing packet may not be
sent to the peer VPN IP directly, but rather to a network behind it. For
this reason we first perform a nexthop lookup in the system routing
table and then we use the retrieved nexthop as peer search key.

With this change an ovpn instance will be able to stay connected to
multiple remote endpoints.
This functionality is strictly required when running ovpn on an
OpenVPN server.

Userspace may want to pass the MSG_NOSIGNAL flag to
tcp_sendmsg() in order to avoid generating a SIGPIPE.
To pass this flag down the TCP stack a new skb sending API
accepting a flags argument is introduced.

When sending an skb over a socket using skb_send_sock_locked(),
it is currently not possible to specify any flag to be set in
msghdr->msg_flags.
However, we may want to pass flags the user may have specified,
like MSG_NOSIGNAL.
Extend __skb_send_sock() with a new argument 'flags' and add a
new interface named skb_send_sock_locked_with_flags().

With this change ovpn is allowed to communicate to peers also via TCP.
Parsing of incoming messages is implemented through the strparser API.
Note that ovpn redefines sk_prot and sk_socket->ops for the TCP socket
used to communicate with the peer.
For this reason it needs to access inet6_stream_ops, which is declared
as extern in the IPv6 module, but it is not fully exported.
Therefore this patch is also adding EXPORT_SYMBOL_GPL(inet6_stream_ops)
to net/ipv6/af_inet6.c.
