Don't use mnl attr helpers, we're trying to remove the libmnl dependency. Create both signed and unsigned helpers, libmnl had unsigned helpers, so code generator no longer needs the mnl_type() hack. The new helpers are written from first principles, but are hopefully not too buggy. Acked-by:

The temporary auto-int helpers are not really correct. We can't treat signed and unsigned ints the same when determining whether we need full 8B. I realized this before sending the patch to add support in libmnl. Unfortunately, that patch has not been merged, so time to fix our local helpers. Use the mnl* name for now, subsequent patches will address that. Acked-by:

Andrew Lunn says: ==================== drivers: net: Convert EEE handling to use linkmode bitmaps EEE has until recently been limited to lower speeds due to the use of the legacy u32 for link speeds. This restriction has been lifted, with the use of linkmode bitmaps, added in the following patches: 1f069de6 ethtool: add linkmode bitmap support to struct ethtool_keee 1d756ff1 ethtool: add suffix _u32 to legacy bitmap members of struct ethtool_keee 285cc15c ethtool: adjust struct ethtool_keee to kernel needs 0b3100bc ethtool: switch back from ethtool_keee to ethtool_eee for ioctl d80a5233 ethtool: replace struct ethtool_eee with a new struct ethtool_keee on kernel side This patchset converts the remaining MAC drivers still using the old _u32 to link modes. A couple of Intel drivers do odd things with EEE, setting the autoneg bit. It is unclear why, no other driver does, ethtool does not display it, and EEE is always negotiated. One patch in this series deletes this code. With all users of the legacy _u32 changed to link modes, the _u32 values are removed from keee, and support for them in the ethtool core is removed. --- Changes in v5: - Restore zeroing eee_data.advertised in ax8817_178a - Fix lp_advertised -> supported in ixgdb - Link to v4: https://lore.kernel.org/r/20240218-keee-u32-cleanup-v4-0-71f13b7c3e60@lunn.ch Changes in v4: - Add missing conversion in igb - Add missing conversion in r8152 - Add patch to remove now unused _u32 members - Link to v3: https://lore.kernel.org/r/20240217-keee-u32-cleanup-v3-0-fcf6b62a0c7f@lunn.ch Changes in v3: - Add list of commits adding linkmodes to EEE to cover letter - Fix grammar error in cover letter. - Add Reviewed-by from Jacob Keller - Link to v2: https://lore.kernel.org/r/20240214-keee-u32-cleanup-v2-0-4ac534b83d66@lunn.ch Changes in v2: - igb: Fix type 100BaseT to 1000BaseT. - Link to v1: https://lore.kernel.org/r/20240204-keee-u32-cleanup-v1-0-fb6e08329d9a@lunn.ch ==================== Signed-off-by:

Updating link clock rate for different speeds is only needed when using RGMII, as that mode requires changing clock speed when the link speed changes. Let's restrict updating the link clock speed in ethqos_update_link_clk() to just RGMII. Other modes such as SGMII only need to enable the link clock (which is already done in probe). Signed-off-by:

This patchset focuses on the IOAM Pre-allocated Trace (the only Option-Type currently supported in the kernel), and so on IOAM "trace" events. See an example of a consumer here [1].

Although a reset method is generally not required, the driver fails to detect the switch if the reset was kept asserted by a previous driver.

Add support for resetting the device using a reset controller, complementing the existing GPIO reset functionality (reset-gpios). Although the reset is optional and the driver performs a soft reset during setup, if the initial reset pin state was asserted, the driver will not detect the device until the reset is deasserted.

Replace macro MAC_ADDRESS_EQUAL() for null_mac_addr checking with inline function__agg_has_partner(). When MAC_ADDRESS_EQUAL() is verifiying aggregator's partner mac addr with null_mac_addr, means that seeing if aggregator has a valid partner or not. Using __agg_has_partner() makes it more clear to understand. In ad_port_selection_logic(), since aggregator->partner_system and port->partner_oper.system has been compared first as a prerequisite, it is safe to replace the upcoming MAC_ADDRESS_EQUAL() for null_mac_addr checking with __agg_has_partner(). Delete null_mac_addr, which is not required anymore in bond_3ad.c, since all references to it are gone. Signed-off-by:

This is an effort to get rid of all multiplications from allocation functions in order to prevent integer overflows [1][2]. As the "port_prox" variable is a pointer to "struct port_proxy" and this structure ends in a flexible array: struct port_proxy { [...] struct t7xx_port ports[]; }; the preferred way in the kernel is to use the struct_size() helper to do the arithmetic instead of the argument "size + size * count" in the devm_kzalloc() function. This way, the code is more readable and safer.

This is a followup of commit 234ec0b6 ("netlink: fix potential sleeping issue in mqueue_flush_file"), because vfree_atomic() overhead is unfortunate for medium sized allocations. 1) If the allocation is smaller than PAGE_SIZE, do not bother with vmalloc() at all. Some arches have 64KB PAGE_SIZE, while NLMSG_GOODSIZE is smaller than 8KB. 2) Use kvmalloc(), which might allocate one high order page instead of vmalloc if memory is not too fragmented.
