net: replace ND_PRINTK with dynamic debug

2025-07-10T22:27:32+00:00

ND_PRINTK with val > 1 only works when the ND_DEBUG was set in compilation phase. Replace it with dynamic debug. Convert ND_PRINTK with val <= 1 to net_{err,warn}_ratelimited, and convert the rest to net_dbg_ratelimited.

ipv6: eliminate ndisc_ops_is_useropt()

2024-08-13T00:23:57+00:00

as it doesn't seem to offer anything of value. There's only 1 trivial user: int lowpan_ndisc_is_useropt(u8 nd_opt_type) { return nd_opt_type == ND_OPT_6CO; } but there's no harm to always treating that as a useropt...

net: 6lowpan: constify lowpan_nhc structures

2022-06-09T19:53:28+00:00

This patch constify the lowpan_nhc declarations. Since we drop the rb node datastructure there is no need for runtime manipulation of this structure.

net: 6lowpan: use array for find nhc id

2022-06-09T19:53:28+00:00

This patch will remove the complete overengineered and overthinking rb data structure for looking up the nhc by nhcid. Instead we using the existing nhc next header array and iterate over it. It works now for 1 byte values only. However there are only 1 byte nhc id values currently supported and IANA also does not specify large than 1 byte values yet. If there are 2 byte values for nhc ids specified we can revisit this data structure and add support for it.

net: 6lowpan: remove const from scalars

2022-06-09T19:53:28+00:00

The keyword const makes no sense for scalar types inside the lowpan_nhc structure. Most compilers will ignore it so we remove the keyword from the scalar types.

6lowpan: iphc: Fix an off-by-one check of array index

2021-07-22T14:19:03+00:00

The bounds check of id is off-by-one and the comparison should be >= rather >. Currently the WARN_ON_ONCE check does not stop the out of range indexing of &ldev->ctx.table[id] so also add a return path if the bounds are out of range.
