2024-02-15net: ipv6/addrconf: clamp preferred_lft to the minimum requiredAlex Henrie
If the preferred lifetime was less than the minimum required lifetime, ipv6_create_tempaddr would error out without creating any new address. On my machine and network, this error happened immediately with the preferred lifetime set to 5 seconds or less, after a few minutes with the preferred lifetime set to 6 seconds, and not at all with the preferred lifetime set to 7 seconds. During my investigation, I found a Stack Exchange post from another person who seems to have had the same problem: They stopped getting new addresses if they lowered the preferred lifetime below 3 seconds, and they didn't really know why. The preferred lifetime is a preference, not a hard requirement. The kernel does not strictly forbid new connections on a deprecated address, nor does it guarantee that the address will be disposed of the instant its total valid lifetime expires. So rather than disable IPv6 privacy extensions altogether if the minimum required lifetime swells above the preferred lifetime, it is more in keeping with the user's intent to increase the temporary address's lifetime to the minimum necessary for the current network conditions. With these fixes, setting the preferred lifetime to 5 or 6 seconds "just works" because the extra fraction of a second is practically unnoticeable. It's even possible to reduce the time before deprecation to 1 or 2 seconds by setting /proc/sys/net/ipv6/conf/*/regen_min_advance and /proc/sys/net/ipv6/conf/*/dad_transmits to 0. I realize that that is a pretty niche use case, but I know at least one person who would gladly sacrifice performance and convenience to be sure that they are getting the maximum possible level of privacy.

2024-02-15net: ipv6/addrconf: introduce a regen_min_advance sysctlAlex Henrie
In RFC 8981, REGEN_ADVANCE cannot be less than 2 seconds, and the RFC does not permit the creation of temporary addresses with lifetimes shorter than that: > When processing a Router Advertisement with a > Prefix Information option carrying a prefix for the purposes of > address autoconfiguration (i.e., the A bit is set), the host MUST > perform the following steps: > 5. A temporary address is created only if this calculated preferred > lifetime is greater than REGEN_ADVANCE time units. However, some users want to change their IPv6 address as frequently as possible regardless of the RFC's arbitrary minimum lifetime. For the benefit of those users, add a regen_min_advance sysctl parameter that can be set to below or above 2 seconds.

2024-02-12can: bcm: add recvmsg flags for own, local and remote trafficNicolas Maier
CAN RAW sockets allow userspace to tell if a received CAN frame comes from the same socket, another socket on the same host, or another host. See commit 1e55659ce6dd ("can-raw: add msg_flags to distinguish local traffic"). However, this feature is missing in CAN BCM sockets. Add the same feature to CAN BCM sockets. When reading a received frame (opcode RX_CHANGED) using recvmsg, two flags in msg->msg_flags may be set following the previous convention (from CAN RAW), to distinguish between 'own', 'local' and 'remote' CAN traffic. Update the documentation to reflect this change.

Example are PHY packages that have some regs only in one PHY of the package and will affect every other PHY in the package, for example related to PHY interface mode calibration or global PHY mode selection. The PHY package node MUST declare the base address used by the PHY driver for global configuration by calculating the offsets of the global PHY based on the base address of the PHY package.

2024-02-08docs: kernel_feat.py: fix build error for missing filesdocs-6.8-fixes2Vegard Nossum
If the directory passed to the '.. kernel-feat::' directive does not exist or the get_feat.pl script does not find any files to extract features from, Sphinx will report the following error: Sphinx parallel build error: UnboundLocalError: local variable 'fname' referenced before assignment make[2]: *** [Documentation/Makefile:102: htmldocs] Error 2 This is due to how I changed the script in c48a7c44a1d0 ("docs: kernel_feat.py: fix potential command injection"). Before that, the filename passed along to self.nestedParse() in this case was weirdly just the whole get_feat.pl invocation. We can fix it by doing what kernel_abi.py does -- just pass self.arguments[0] as 'fname'.

2024-02-06bonding: Add independent control state machineAahil Awatramani
Add support for the independent control state machine per IEEE 802.1AX-2008 5.4.15 in addition to the existing implementation of the coupled control state machine. Introduces two new states, AD_MUX_COLLECTING and AD_MUX_DISTRIBUTING in the LACP MUX state machine for separated handling of an initial Collecting state before the Collecting and Distributing state. This enables a port to be in a state where it can receive incoming packets while not still distributing. This is useful for reducing packet loss when a port begins distributing before its partner is able to collect. Added new functions such as bond_set_slave_tx_disabled_flags and bond_set_slave_rx_enabled_flags to precisely manage the port's collecting and distributing states. Previously, there was no dedicated method to disable TX while keeping RX enabled, which this patch addresses. Note that the regular flow process in the kernel's bonding driver remains unaffected by this patch. The extension requires explicit opt-in by the user (in order to ensure no disruptions for existing setups) via netlink support using the new bonding parameter coupled_control. The default value for coupled_control is set to 1 so as to preserve existing behaviour.

2024-02-05net: marvell,prestera: Fix example PCI bus addressingRob Herring
The example for PCI devices has some addressing errors. 'reg' is written as if the parent bus is PCI, but the default bus for examples is 1 address and size cell. 'ranges' is defining config space with a size of 0. Generally, config space should not be defined in 'ranges', only PCI memory and I/O spaces. Fix these issues by updating the values with made-up, but valid values. This was uncovered with recent dtschema changes.

This commit adds the dt-binding for KSZ8567, a robust 7-port Ethernet switch. The KSZ8567 features two RGMII/MII/RMII interfaces, each capable of gigabit speeds, complemented by five 10/100 Mbps MAC/PHYs. This binding is necessary to set specific capabilities for this switch chip that are necessary due to the ksz dsa driver only accepting specific chip ids. The KSZ8567 is very similar to KSZ9567 however only containing 100 Mbps phys on its downstream ports.
