Future proof commit. This switch have 2 CPU ports and one valid configuration is first CPU port set to sgmii and second CPU port set to rgmii-id. The current implementation detects delay only for CPU port zero set to rgmii and doesn't count any delay set in a secondary CPU port. Drop the current delay scan function and move it to the sgmii parser function to generalize and implicitly add support for secondary CPU port set to rgmii-id. Introduce new logic where delay is enabled also with internal delay binding declared and rgmii set as PHY mode. Signed-off-by:

Currently CPU port is always hardcoded to port 0. This switch have 2 CPU ports. The original intention of this driver seems to be use the mac06_exchange bit to swap MAC0 with MAC6 in the strange configuration where device have connected only the CPU port 6. To skip the introduction of a new binding, rework the driver to address the secondary CPU port as primary and drop any reference of hardcoded port. With configuration of mac06 exchange, just skip the definition of port0 and define the CPU port as a secondary. The driver will autoconfigure the switch to use that as the primary CPU port.

Add support for this in the qca8k driver. Also add support for SGMII rx/tx clock falling edge. This is only present for pad0, pad5 and pad6 have these bit reserved from Documentation. Add a comment that this is hardcoded to PAD0 as qca8327/28/34/37 have an unique sgmii line and setting falling in port0 applies to both configuration with sgmii used for port0 or port6.

As the 32-bit arch with 64-bit DMA seems to rare those days, and page pool might carry a lot of code and complexity for systems that possibly. So disable dma mapping support for such systems, if drivers really want to work on such systems, they have to implement their own DMA-mapping fallback tracking outside page_pool. Reviewed-by:

The combination of NUD_PERMANENT + NTF_MANAGED is not supported and does not make sense either given the former indicates a static/fixed neighbor entry whereas the latter a dynamically resolved one. While it is possible to transition from one over to the other, we should however reject such creation attempts.

Instead of open-coding a check for invalid bits in NTF_EXT_MASK, we can just use the NLA_POLICY_MASK() helper instead, and simplify NDA_FLAGS_EXT sanity check this way. Suggested-by:
-
Daniel Borkmann authored
Currently, NDA_FLAGS_EXT flags allow a maximum of 24 bits to be used for extended neighbor flags. These are eventually fed into neigh->flags by shifting with NTF_EXT_SHIFT as per commit 2c611ad9 ("net, neigh: Extend neigh->flags to 32 bit to allow for extensions"). If really ever needed in future, the full 32 bits from NDA_FLAGS_EXT can be used, it would only require to move neigh->flags from u32 to u64 inside the kernel. Add a build-time assertion such that when extending the NTF_EXT_MASK with new bits, we'll trigger an error once we surpass the 24th bit. This assumes that no bit holes in new NTF_EXT_* flags will slip in from UAPI, but I think this is reasonable to assume. Suggested-by:

It seems reasonable to fine-tune only some of the skew values when using one of the rgmii-*id PHY modes, and even when all skew values are specified, using the correct ID PHY mode makes sense for documentation purposes. Such a configuration also appears in the binding docs in Documentation/devicetree/bindings/net/micrel-ksz90x1.txt, so the driver should not warn about it. Signed-off-by:

random_ether_addr() was the original name of the helper which was kept for backward compatibility (?) after the rename in commit 0a4dd594 ("etherdevice: Rename random_ether_addr to eth_random_addr").

This big patch sprinkles const on local variables and function arguments which may refer to netdev->dev_addr. Commit 406f42fa ("net-next: When a bond have a massive amount of VLANs...") introduced a rbtree for faster Ethernet address look up. To maintain netdev->dev_addr in this tree we need to make all the writes to it got through appropriate helpers. Some of the changes here are not strictly required - const is sometimes cast off but pointer is not used for writing. It seems like it's still better to add the const in case the code changes later or relevant -W flags get enabled for the build. No functional changes.

In icmp_build_probe(), the icmp_ext_echo_iio parsing should be done step by step and skb_header_pointer() return value should always be checked, this patch fixes 3 places in there: - On case ICMP_EXT_ECHO_CTYPE_NAME, it should only copy ident.name from skb by skb_header_pointer(), its len is ident_len. Besides, the return value of skb_header_pointer() should always be checked. - On case ICMP_EXT_ECHO_CTYPE_INDEX, move ident_len check ahead of skb_header_pointer(), and also do the return value check for skb_header_pointer(). - On case ICMP_EXT_ECHO_CTYPE_ADDR, before accessing iio->ident.addr. ctype3_hdr.addrlen, skb_header_pointer() should be called first, then check its return value and ident_len. On subcases ICMP_AFI_IP and ICMP_AFI_IP6, also do check for ident. addr.ctype3_hdr.addrlen and skb_header_pointer()'s return value. On subcase ICMP_AFI_IP, the len for skb_header_pointer() should be "sizeof(iio->extobj_hdr) + sizeof(iio->ident.addr.ctype3_hdr) + sizeof(struct in_addr)" or "ident_len". v1->v2: - To make it more clear, call skb_header_pointer() once only for iio->indent's parsing as Jakub Suggested. v2->v3: - The extobj_hdr.length check against sizeof(_iio) should be done before calling skb_header_pointer(), as Eric noticed.
