Maxime Chevallier says: ==================== Followup fixes for the dwmac and altera lynx conversion Here's yet another version of the cleanup series for the TSE PCS replacement by PCS Lynx. It includes Kconfig fixups, some missing initialisations and a slight rework suggested by Russell for the dwmac cleanup sequence, along with more explicit zeroing of local structures as per MAciej's review. ==================== Link: https://lore.kernel.org/r/20230607135941.407054-1-maxime.chevallier@bootlin.comSigned-off-by:

Jakub Kicinski authored
When parsing multi-attr we count the objects and then allocate an array to hold the parsed objects. If an attr space has multiple multi-attr objects, however, if parsing the first array fails we'll leave the object count for the second even tho the second array was never allocated. This may cause crashes when freeing objects on error. Count attributes to a variable on the stack and only set the count in the object once the memory was allocated. Signed-off-by: -

txgbe_shutdown() relies on txgbe_dev_shutdown() to initialise wake by passing it by reference. However, txgbe_dev_shutdown() doesn't use this parameter at all. wake is then passed uninitialised by txgbe_dev_shutdown() to pci_wake_from_d3(). Resolve this problem by: * Removing the unused parameter from txgbe_dev_shutdown() * Removing the uninitialised variable wake from txgbe_dev_shutdown() * Passing false to pci_wake_from_d3() - this assumes that although uninitialised wake was in practice false (0). I'm not sure that this counts as a bug, as I'm not sure that it manifests in any unwanted behaviour. But in any case, the issue was introduced by: 3ce7547e ("net: txgbe: Add build support for txgbe") Flagged by Smatch as: .../txgbe_main.c:486 txgbe_shutdown() error: uninitialized symbol 'wake'. No functional change intended. Compile tested only. Signed-off-by:

Guillaume Nault says: ==================== ipv4: Remove RT_CONN_FLAGS() calls in flowi4_init_output(). Remove a few RT_CONN_FLAGS() calls used inside flowi4_init_output(). These users can be easily converted to set the scope properly, instead of overloading the tos parameter with scope information as done by RT_CONN_FLAGS(). The objective is to eventually remove RT_CONN_FLAGS() entirely, which will then allow to also remove RTO_ONLINK and to finally convert ->flowi4_tos to dscp_t. ==================== Link: https://lore.kernel.org/r/cover.1685999117.git.gnault@redhat.comSigned-off-by:

RT_CONN_FLAGS(sk) overloads flowi4_tos with the RTO_ONLINK bit when sk has the SOCK_LOCALROUTE flag set. This allows ip_route_output_key_hash() to eventually adjust flowi4_scope. Instead of relying on special handling of the RTO_ONLINK bit, we can just set the route scope correctly. This will eventually allow to avoid special interpretation of tos variables and to convert ->flowi4_tos to dscp_t. Signed-off-by:

Robert Hancock <robert.hancock@calian.com> Reviewed-by:

Robert Hancock authored
The ksz9477 DSA switch driver is currently updating some MMD registers on the internal port PHYs to address some chip errata. However, these errata are really a property of the PHY itself, not the switch they are part of, so this is kind of a layering violation. It makes more sense for these writes to be done inside the driver which binds to the PHY and not the driver for the containing device. This also addresses some issues where the ordering of when these writes are done may have been incorrect, causing the link to erratically fail to come up at the proper speed or at all. Doing this in the PHY driver during config_init ensures that they happen before anything else tries to change the state of the PHY on the port. The new code also ensures that autonegotiation is disabled during the register writes and re-enabled afterwards, as indicated by the latest version of the errata documentation from Microchip.

Jakub Kicinski says: ==================== tools: ynl: user space C Use the code gen which is already in tree to generate a user space library for a handful of simple families. I find YNL C quite useful in some WIP projects, and I think others may find it useful, too. I was hoping someone will pick this work up and finish it... but it seems that Python YNL has largely stolen the thunder. Python may not be great for selftest, tho, and actually this lib is more fully-featured. The Python script was meant as a quick demo, funny how those things go. v2: https://lore.kernel.org/all/20230604175843.662084-1-kuba@kernel.org/ v1: https://lore.kernel.org/all/20230603052547.631384-1-kuba@kernel.org/ ==================== Link: https://lore.kernel.org/r/20230605190108.809439-1-kuba@kernel.orgSigned-off-by:
