Bernard reported that trying to unload rose module would lead to infamous messages: unregistered_netdevice: waiting for rose0 to become free. Usage count = xx This patch solves the issue, by making sure each socket referring to a netdevice holds a reference count on it, and properly releases it in rose_release(). rose_dev_first() is also fixed to take a device reference before leaving the rcu_read_locked section. Following patch will add ref_tracker annotations to ease future bug hunting. Fixes: 1da177e4 ("Linux-2.6.12-rc2") Reported-by:

Tony Nguyen says: ==================== 1GbE Intel Wired LAN Driver Updates 2022-07-28 Jacob Keller says: Convert all of the Intel drivers with PTP support to the newer .adjfine implementation which uses scaled parts per million. This improves the precision of the frequency adjustments by taking advantage of the full scaled parts per million input coming from user space. In addition, all implementations are converted to using the mul_u64_u64_div_u64 function which better handles the intermediate value. This function supports architecture specific instructions where possible to avoid loss of precision if the normal 64-bit multiplication would overflow. Of note, the i40e implementation is now able to avoid loss of precision on slower link speeds by taking advantage of this to multiply by the link speed factor first. This results in a significantly more precise adjustment by allowing the calculation to impact the lower bits. This also gets us a step closer to being able to remove the .adjfreq entirely by removing its use from many drivers. I plan to follow this up with a series to update the drivers from other vendors and drop the .adjfreq implementation entirely. * '1GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/next-queue: igb: convert .adjfreq to .adjfine ixgbe: convert .adjfreq to .adjfine i40e: convert .adjfreq to .adjfine i40e: use mul_u64_u64_div_u64 for PTP frequency calculation e1000e: convert .adjfreq to .adjfine e1000e: remove unnecessary range check in e1000e_phc_adjfreq ice: implement adjfine with mul_u64_u64_div_u64 ==================== Link: https://lore.kernel.org/r/20220728181836.3387862-1-anthony.l.nguyen@intel.comSigned-off-by:

The 1st patch is by me and fixes a typo in the mcp251xfd driver. Vincent Mailhol contributes a series of 9 patches, which clean up the drivers to make use of KBUILD_MODNAME instead of hard coded names and remove DRV_VERSION. Followed by 3 patches by Vincent Mailhol that directly set the ethtool_ops in instead of calling a function in the slcan, c_can and flexcan driver. Vincent Mailhol contributes a KBUILD_MODNAME and pr_fmt cleanup patch for the slcan driver. Dario Binacchi contributes 6 patches to clean up the driver and remove the legacy driver infrastructure. The next 14 patches are by Vincent Mailhol and target the various drivers, they add ethtool support and reporting of timestamping capabilities. Another patch by Vincent Mailhol for the etas_es58x driver to remove useless calls to usb_fill_bulk_urb(). The last patch is by Christophe JAILLET and fixes a broken link to Documentation in the can327 driver. ==================== Signed-off-by:

Representors do not want to be subject to the PF's Ethernet address filters, since traffic from VFs will typically have a destination either elsewhere on the link segment or on an overlay network. So, create a dynamic m-port with promiscuous and all-multicast filters, and set it as the egress port of representor default rules. Since the m-port is an alias of the calling PF's own m-port, traffic will still be delivered to the PF's RXQs, but it will be subject to the VNRX filter rules installed on the dynamic m-port (specified by the v-port ID field of the filter spec).

We need to be able to drop the efx->filter_sem in ef100_filter_table_up() so that we can call functions that insert filters (and thus take that rwsem for read), which means the efx->type->filter_table_probe method needs to be responsible for taking the lock in the first place. Signed-off-by:

Default rules are low-priority switching rules which the hardware uses in the absence of higher-priority rules. Each representor requires a corresponding rule matching traffic from its representee VF and delivering to the PF (where a check on INGRESS_MPORT in __ef100_rx_packet() will direct it to the representor). No rule is required in the reverse direction, because representor TX uses a TX override descriptor to bypass the MAE and deliver directly to the VF. Since inserting any rule into the MAE disables the firmware's own default rules, also insert a pair of rules to connect the PF to the physical network port and vice-versa. Signed-off-by:

Traffic delivered to the (MAE admin) PF could be from either the wire or a VF. The INGRESS_MPORT field of the RX prefix distinguishes these; base_mport is the value this field will have for traffic from the wire (which should be delivered to the PF's netdevice, not a representor). Signed-off-by:

Edward Cree authored
Representor RX uses a NAPI context driven by a 'fake interrupt': when the parent PF receives a packet destined for the representor, it adds it to an SKB list (efv->rx_list), and schedules NAPI if the 'fake interrupt' is primed. The NAPI poll then pulls packets off this list and feeds them to the stack with netif_receive_skb_list(). This scheme allows us to decouple representor RX from the parent PF's RX fast-path. This patch implements the 'top half', which builds an SKB, copies data into it from the RX buffer (which can then be released), adds it to the queue and fires the 'fake interrupt' if necessary.
