As it says in rfc8260#section-3.5 about the fair capacity scheduler: A fair capacity distribution between the streams is used. This scheduler considers the lengths of the messages of each stream and schedules them in a specific way to maintain an equal capacity for all streams. The details are implementation dependent. interleaving user messages allows for a better realization of the fair capacity usage. This patch adds Fair Capacity Scheduler based on the foundations added by commit 5bbbbe32 ("sctp: introduce stream scheduler foundations"): A fc_list and a fc_length are added into struct sctp_stream_out_ext and a fc_list is added into struct sctp_stream. In .enqueue, when there are chunks enqueued into a stream, this stream will be linked into stream-> fc_list by its fc_list ordered by its fc_length. In .dequeue, it always picks up the 1st skb from stream->fc_list. In .dequeue_done, fc_length is increased by chunk's len and update its location in stream->fc_list according to the its new fc_length. Note that when the new fc_length overflows in .dequeue_done, instead of resetting all fc_lengths to 0, we only reduced them by U32_MAX / 4 to avoid a moment of imbalance in the scheduling, as Marcelo suggested.

Russell King says: ==================== Various mtk_eth_soc cleanups Here are a number of patches that do a bit of cleanup to mtk_eth_soc. The first patch cleans up mtk_gmac0_rgmii_adjust(), which is the troublesome function preventing the driver becoming a post-March2020 phylink driver. It doesn't solve that problem, merely makes the code easier to follow by getting rid of repeated tenary operators. The second patch moves the check for DDR2 memory to the initialisation of phylink's supported_interfaces - if TRGMII is not possible for some reason, we should not be erroring out in phylink MAC operations when that can be determined prior to phylink creation. The third patch removes checks from mtk_mac_config() that are done when initialising supported_interfaces - phylink will not call mtk_mac_config() with an interface that was not marked as supported, so these checks are redundant. The last patch removes the remaining vestiges of REVMII and RMII support, which appears to be entirely unused. These shouldn't conflict with Daniel's patch set, but if they do I will rework as appropriate. ==================== Link: https://lore.kernel.org/r/ZAdj9qUXcHUsK7Gt@shell.armlinux.org.ukSigned-off-by:

Since the conversion of mtk_eth_soc to phylink's supported_interfaces bitmap, these two modes have not been selectable. No one has raised this as an issue. Checking the in-kernel DT files, none of them use either of these modes with this hardware. Daniel Golle concurs: A quick grep through the device trees of the more than 650 ramips and mediatek boards we support in OpenWrt has revealed that *none* of them uses either reduced-MII or reverse-MII PHY modes. I could imaging that some more specialized ramips boards may use the RMII 100M PHY mode to connect with exotic PHYs for industrial or automotive applications (think: for 100BASE-T1 PHY connected via RMII). I have never seen or touched such boards, but there are hints that they do exist. For reverse-MII there are cases in which the Ralink SoC (Rt305x, for example) is used in iNIC mode, ie. connected as a PHY to another SoC, and running only a minimal firmware rather than running Linux. Due to the lack of external DRAM for the Ralink SoC on this kind of boards, the Ralink SoC there will anyway never be able to boot Linux. I've seen this e.g. in multimedia devices like early WiFi-connected not-yet-so-smart TVs. Consequently, the conclusion is that no one uses these modes with this hardware, so we might as well drop support for them. Signed-off-by:

mtk_mac_config() checks that the interface mode is permitted for the capabilities, but we already do these checks in mtk_add_mac() when initialising phylink's supported_interfaces bitmap. Remove the unnecessary tests. Signed-off-by:

If TRGMII mode is not permitted when using DDR2 mode, we should handle that when setting up phylink's ->supported_interfaces so phylink knows that this is not supported by the hardware. Move this check to mtk_add_mac(). Signed-off-by:

Get rid of the multiple tenary operators in mtk_gmac0_rgmii_adjust() replacing them with a single if(), thus making the code easier to read. Signed-off-by:

Remove driver code to do this and remove unnecessary includes of <linux/aer.h> from several other drivers.

pci_enable_pcie_error_reporting() enables the device to send ERR_* Messages. Since f26e58bf ("PCI/AER: Enable error reporting when AER is native"), the PCI core does this for all devices during enumeration, so the driver doesn't need to do it itself. Remove the redundant pci_enable_pcie_error_reporting() call from the driver. Also remove the corresponding pci_disable_pcie_error_reporting() from the driver .remove() path. Note that this only controls ERR_* Messages from the device. An ERR_* Message may cause the Root Port to generate an interrupt, depending on the AER Root Error Command register managed by the AER service driver. Signed-off-by:

R-Car H3 ES1.* was only available to an internal development group and needed a lot of quirks and workarounds. These become a maintenance burden now, so our development group decided to remove upstream support and disable booting for this SoC. Public users only have ES2 onwards. Reviewed-by:

Commit 62622dab ("ima: return IMA digest value only when IMA_COLLECTED flag is set") caused bpf_ima_inode_hash() to refuse to give non-fresh digests. IMA test #3 assumed the old behavior, that bpf_ima_inode_hash() still returned also non-fresh digests. Correct the test by accepting both cases. If the samples returned are 1, assume that the commit above is applied and that the returned digest is fresh. If the samples returned are 2, assume that the commit above is not applied, and check both the non-fresh and fresh digest.

Commit 0091bfc8 ("io_uring/af_unix: defer registered files gc to io_uring release") added one bit to struct sk_buff. This structure is critical for networking, and we try very hard to not add bloat on it, unless absolutely required. For instance, we can use a specific destructor as a wrapper around unix_destruct_scm(), to identify skbs that unix_gc() has to special case. Signed-off-by:

Steen Hegelund says: ==================== Add support for TC flower templates in Sparx5 This adds support for the TC template mechanism in the Sparx5 flower filter implementation. Templates are as such handled by the TC framework, but when a template is created (using a chain id) there are by definition no filters on this chain (an error will be returned if there are any). If the templates chain id is one that is represented by a VCAP lookup, then when the template is created, we know that it is safe to use the keys provided in the template to change the keyset configuration for the (port, lookup) combination, if this is needed to improve the match on the template. The original port keyset configuration is captured in the template state information which is kept per port, so that when the template is deleted the port keyset configuration can be restored to its previous setting. The template also provides the protocol parameter which is the basic information that is used to find out which port keyset configuration needs to be changed. The VCAPs and lookups are slightly different when it comes to which keys, keysets and protocol are supported and used for selection, so in some cases a bit of tweaking is needed to find a useful match. This is done by e.g. removing a key that prevents the best matching keyset from being selected. The debugfs output that is provided for a port allows inspection of the currently used keyset in each of the VCAPs lookups. So when a template has been created the debugfs output allows you to verify if the keyset configuration has been changed successfully. ==================== Signed-off-by:
