The initial value of err is -ENOBUFS, and err is guaranteed to be less than 0 before all goto errout. Therefore, on the error path of errout, there is no need to repeatedly judge that err is less than 0, and delete redundant judgments to make the code more concise. Signed-off-by:

Maxime Chevallier says: ==================== Introduce PHY listing and link_topology tracking This is V18 of the phy_link_topology series, aiming at improving support for multiple PHYs being attached to the same MAC. V18 is a simple rebase of the V17 on top of net-next, gathering the tested-by and reviewed-by tags from Christophe (thanks !). This iteration is also one patch shorter than V17 (patch 12/14 in V17 is gone), as one of the patches used to fix an issue that has now been resolved by Simon Horman in 743ff021 ethtool: Don't check for NULL info in prepare_data callbacks As a remainder, here's what the PHY listings would look like : - eth0 has a 88x3310 acting as media converter, and an SFP module with an embedded 88e1111 PHY - eth2 has a 88e1510 PHY PHY for eth0: PHY index: 1 Driver name: mv88x3310 PHY device name: f212a600.mdio-mii:00 Downstream SFP bus name: sfp-eth0 Upstream type: MAC PHY for eth0: PHY index: 2 Driver name: Marvell 88E1111 PHY device name: i2c:sfp-eth0:16 Upstream type: PHY Upstream PHY index: 1 Upstream SFP name: sfp-eth0 PHY for eth2: PHY index: 1 Driver name: Marvell 88E1510 PHY device name: f212a200.mdio-mii:00 Upstream type: MAC Ethtool patches : https://github.com/minimaxwell/ethtool/tree/mc/topo-v16 (this branch is compatible with this V18 series) Link to V17: https://lore.kernel.org/netdev/20240709063039.2909536-1-maxime.chevallier@bootlin.com/ Link to V16: https://lore.kernel.org/netdev/20240705132706.13588-1-maxime.chevallier@bootlin.com/ Link to V15: https://lore.kernel.org/netdev/20240703140806.271938-1-maxime.chevallier@bootlin.com/ Link to V14: https://lore.kernel.org/netdev/20240701131801.1227740-1-maxime.chevallier@bootlin.com/ Link to V13: https://lore.kernel.org/netdev/20240607071836.911403-1-maxime.chevallier@bootlin.com/ Link to v12: https://lore.kernel.org/netdev/20240605124920.720690-1-maxime.chevallier@bootlin.com/ Link to v11: https://lore.kernel.org/netdev/20240404093004.2552221-1-maxime.chevallier@bootlin.com/ Link to V10: https://lore.kernel.org/netdev/20240304151011.1610175-1-maxime.chevallier@bootlin.com/ Link to V9: https://lore.kernel.org/netdev/20240228114728.51861-1-maxime.chevallier@bootlin.com/ Link to V8: https://lore.kernel.org/netdev/20240220184217.3689988-1-maxime.chevallier@bootlin.com/ Link to V7: https://lore.kernel.org/netdev/20240213150431.1796171-1-maxime.chevallier@bootlin.com/ Link to V6: https://lore.kernel.org/netdev/20240126183851.2081418-1-maxime.chevallier@bootlin.com/ Link to V5: https://lore.kernel.org/netdev/20231221180047.1924733-1-maxime.chevallier@bootlin.com/ Link to V4: https://lore.kernel.org/netdev/20231215171237.1152563-1-maxime.chevallier@bootlin.com/ Link to V3: https://lore.kernel.org/netdev/20231201163704.1306431-1-maxime.chevallier@bootlin.com/ Link to V2: https://lore.kernel.org/netdev/20231117162323.626979-1-maxime.chevallier@bootlin.com/ Link to V1: https://lore.kernel.org/netdev/20230907092407.647139-1-maxime.chevallier@bootlin.com/ More discussions on specific issues that happened in 6.9-rc: https://lore.kernel.org/netdev/20240412104615.3779632-1-maxime.chevallier@bootlin.com/ https://lore.kernel.org/netdev/20240429131008.439231-1-maxime.chevallier@bootlin.com/ https://lore.kernel.org/netdev/20240507102822.2023826-1-maxime.chevallier@bootlin.com/ ==================== Signed-off-by:

There are a few PHY drivers that can handle SFP modules through their sfp_upstream_ops. Introduce Phylib helpers to keep track of connected SFP PHYs in a netdevice's namespace, by adding the SFP PHY to the upstream PHY's netdev's namespace. By doing so, these SFP PHYs can be enumerated and exposed to users, which will be able to use their capabilities. Signed-off-by:

Maxime Chevallier authored
Link topologies containing multiple network PHYs attached to the same net_device can be found when using a PHY as a media converter for use with an SFP connector, on which an SFP transceiver containing a PHY can be used. With the current model, the transceiver's PHY can't be used for operations such as cable testing, timestamping, macsec offload, etc. The reason being that most of the logic for these configuration, coming from either ethtool netlink or ioctls tend to use netdev->phydev, which in multi-phy systems will reference the PHY closest to the MAC. Introduce a numbering scheme allowing to enumerate PHY devices that belong to any netdev, which can in turn allow userspace to take more precise decisions with regard to each PHY's configuration. The numbering is maintained per-netdev, in a phy_device_list. The numbering works similarly to a netdevice's ifindex, with identifiers that are only recycled once INT_MAX has been reached. This prevents races that could occur between PHY listing and SFP transceiver removal/insertion. The identifiers are assigned at phy_attach time, as the numbering depends on the netdevice the phy is attached to. The PHY index can be re-used for PHYs that are persistent. Signed-off-by:

Ido Schimmel says: ==================== Unmask upper DSCP bits - part 1 tl;dr - This patchset starts to unmask the upper DSCP bits in the IPv4 flow key in preparation for allowing IPv4 FIB rules to match on DSCP. No functional changes are expected. The TOS field in the IPv4 flow key ('flowi4_tos') is used during FIB lookup to match against the TOS selector in FIB rules and routes. It is currently impossible for user space to configure FIB rules that match on the DSCP value as the upper DSCP bits are either masked in the various call sites that initialize the IPv4 flow key or along the path to the FIB core. In preparation for adding a DSCP selector to IPv4 and IPv6 FIB rules, we need to make sure the entire DSCP value is present in the IPv4 flow key. This patchset starts to unmask the upper DSCP bits in the various places that invoke the core FIB lookup functions directly (patches #1-#7) and in the input route path (patches #8-#12). Future patchsets will do the same in the output route path. No functional changes are expected as commit 1fa3314c ("ipv4: Centralize TOS matching") moved the masking of the upper DSCP bits to the core where 'flowi4_tos' is matched against the TOS selector. ==================== Link: https://patch.msgid.link/20240821125251.1571445-1-idosch@nvidia.comSigned-off-by:

As explained in commit 35ebf65e ("ipv4: Create and use fib_compute_spec_dst() helper."), the function is used - for example - to determine the source address for an ICMP reply. If we are responding to a multicast or broadcast packet, the source address is set to the source address that we would use if we were to send a packet to the unicast source of the original packet. This address is determined by performing a FIB lookup and using the preferred source address of the resulting route. Unmask the upper DSCP bits of the DS field of the packet that triggered the reply so that in the future the FIB lookup could be performed according to the full DSCP value.

Unmask the upper DSCP bits when calling ipmr_fib_lookup() so that in the future it could perform the FIB lookup according to the full DSCP value. Note that ipmr_fib_lookup() performs a FIB rule lookup (returning the relevant routing table) and that IPv4 multicast FIB rules do not support matching on TOS / DSCP. However, it is still worth unmasking the upper DSCP bits in case support for DSCP matching is ever added. Signed-off-by:

And as cfg->tcs is a u8, the range is 0 - 255. Further, on inspecting the code, it seems that cfg->tcs will never be more than AQ_CFG_TCS_MAX (8), so the range is actually 0 - 8. So, it seems that the condition that GCC flags will not occur. But, nonetheless, it would be nice if it didn't emit the warning. It seems that this can be achieved by changing the format specifier from %d to %u, in which case I believe GCC recognises an upper bound on the range of tc of 0 - 255. After some experimentation I think this is due to the combination of the use of %u and the type of cfg->tcs (u8). Empirically, updating the type of the tc variable to unsigned int has the same effect. As both of these changes seem to make sense in relation to what the code is actually doing - iterating over unsigned values - do both. Compile tested only. Signed-off-by: -
