2024-10-17net: phy: realtek: merge the drivers for internal NBase-T PHY'sHeiner Kallweit1-10/+43
The Realtek RTL8125/RTL8126 NBase-T MAC/PHY chips have internal PHY's which are register-compatible, at least for the registers we use here. So let's use just one PHY driver to support all of them. These internal PHY's exist also as external C45 PHY's, but on the internal PHY's no access to MMD registers is possible. This can be used to differentiate between the internal and external version. As a side effect the drivers for two now external-only drivers don't require read_mmd/write_mmd hooks any longer.

2024-10-17eth: fbnic: Add hardware monitoring support via HWMON interfaceSanman Pradhan7-0/+126
This patch adds support for hardware monitoring to the fbnic driver, allowing for temperature and voltage sensor data to be exposed to userspace via the HWMON interface. The driver registers a HWMON device and provides callbacks for reading sensor data, enabling system admins to monitor the health and operating conditions of fbnic.

2024-10-17ethtool: rss: prevent rss ctx deletion when in useDaniel Zahka3-0/+56
ntuple filters can specify an rss context to use for packet hashing and queue selection. When a filter is referencing an rss context, it should be invalid for that context to be deleted. A list of active ntuple filters and their associated rss contexts can be compiled by querying a device's ethtool_ops.get_rxnfc. This patch checks to see if any ntuple filters are referencing an rss context during context deletion, and prevents the deletion if the requested context is still in use.

2024-10-16rtnetlink: Panic when __rtnl_register_many() fails for builtin callers.Kuniyuki Iwashima1-0/+4
We will replace all rtnl_register() and rtnl_register_module() with rtnl_register_many(). Currently, rtnl_register() returns nothing and prints an error message when it fails to register a rtnetlink message type and handlers. The failure happens only when rtnl_register_internal() fails to allocate rtnl_msg_handlers[protocol][msgtype], but it's unlikely for built-in callers on boot time. rtnl_register_many() unwinds the previous successful registrations on failure and returns an error, but it will be useless for built-in callers, especially some subsystems that do not have the legacy ioctl() interface and do not work without rtnetlink. Instead of booting up without rtnetlink functionality, let's panic on failure for built-in rtnl_register_many() callers.

Ignat Korchagin says: ==================== do not leave dangling sk pointers in pf->create functions Some protocol family create() implementations have an error path after allocating the sk object and calling sock_init_data(). sock_init_data() attaches the allocated sk object to the sock object, provided by the caller. If the create() implementation errors out after calling sock_init_data(), it releases the allocated sk object, but the caller ends up having a dangling sk pointer in its sock object on return. Subsequent manipulations on this sock object may try to access the sk pointer, because it is not NULL thus creating a use-after-free scenario. We have implemented a stable hotfix in commit 631083143315 ("net: explicitly clear the sk pointer, when pf->create fails"), but this series aims to fix it properly by going through each of the pf->create() implementations and making sure they all don't return a sock object with a dangling pointer on error. ==================== Link: https://patch.msgid.link/20241014153808.51894-1-ignat@cloudflare.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>

cxgb4_get_srq_entry() has been unused since 2018's commit e47094751ddc ("cxgb4: Add support to initialise/read SRQ entries") which added it. Remove it. Note: I'm a bit suspicious whether any of the srq code in there actually does anything useful; without this get I can't see anything that reads the data, so perhaps the whole thing should go? But that however would remove one of the opcode handlers, and I have no way to test that.

2024-10-15net: txgbe: Pass string literal as format argument of alloc_workqueue()Simon Horman1-1/+1
Recently I noticed that both gcc-14 and clang-18 report that passing a non-string literal as the format argument of clkdev_create() is potentially insecure. E.g. clang-18 says: .../txgbe_phy.c:582:35: warning: format string is not a string literal (potentially insecure) [-Wformat-security] 581 | clock = clkdev_create(clk, NULL, clk_name); | ^~~~~~~~ .../txgbe_phy.c:582:35: note: treat the string as an argument to avoid this 581 | clock = clkdev_create(clk, NULL, clk_name); | ^ | "%s", It is always the case where the contents of clk_name is safe to pass as the format argument. That is, in my understanding, it never contains any format escape sequences. However, it seems better to be safe than sorry. And, as a bonus, compiler output becomes less verbose by addressing this issue as suggested by clang-18. Compile tested only.

2024-10-15net: dsa: microchip: copy string using strscpySimon Horman1-1/+1
Prior to this patch ksz_ptp_msg_irq_setup() uses snprintf() to copy strings. It does so by passing strings as the format argument of snprintf(). This appears to be safe, due to the absence of format specifiers in the strings, which are declared within the same function. But nonetheless GCC 14 warns about it: .../ksz_ptp.c:1109:55: warning: format string is not a string literal (potentially insecure) [-Wformat-security] 1109 | snprintf(ptpmsg_irq->name, sizeof(ptpmsg_irq->name), name[n]); | ^~~~~~~ .../ksz_ptp.c:1109:55: note: treat the string as an argument to avoid this 1109 | snprintf(ptpmsg_irq->name, sizeof(ptpmsg_irq->name), name[n]); | ^ | "%s", As what we are really dealing with here is a string copy, it seems make sense to use a function designed for this purpose. In this case null padding is not required, so strscpy is appropriate. And as the destination is an array of fixed size, the 2-argument variant may be used.
