UAPI: net/sched: Use __struct_group() in flex struct tc_u32_sel

2024-08-15T03:37:47+00:00

Use the `__struct_group()` helper to create a new tagged `struct tc_u32_sel_hdr`. This structure groups together all the members of the flexible `struct tc_u32_sel` except the flexible array. As a result, the array is effectively separated from the rest of the members without modifying the memory layout of the flexible structure. This new tagged struct will be used to fix problematic declarations of middle-flex-arrays in composite structs[1]. [1] https://git.kernel.org/linus/d88cabfd9abc Signed-off-by: Gustavo A. R.

net/sched: cls_flower: rework TCA_FLOWER_KEY_ENC_FLAGS usage

2024-07-15T16:14:38+00:00

This patch changes how TCA_FLOWER_KEY_ENC_FLAGS is used, so that it is used with TCA_FLOWER_KEY_FLAGS_* flags, in the same way as TCA_FLOWER_KEY_FLAGS is currently used. Where TCA_FLOWER_KEY_FLAGS uses {key,mask}->control.flags, then TCA_FLOWER_KEY_ENC_FLAGS now uses {key,mask}->enc_control.flags, therefore {key,mask}->enc_flags is now unused. As the generic fl_set_key_flags/fl_dump_key_flags() is used with encap set to true, then fl_{set,dump}_key_enc_flags() is removed. This breaks unreleased userspace API (net-next since 2024-06-04).

net/sched: flower: define new tunnel flags

2024-07-15T16:14:38+00:00

Define new TCA_FLOWER_KEY_FLAGS_* flags for use in struct flow_dissector_key_control, covering the same flags as currently exposed through TCA_FLOWER_KEY_ENC_FLAGS. Put the new flags under FLOW_DIS_F_*. The idea is that we can later, move the existing flags under FLOW_DIS_F_* as well. The ynl flag names have been taken from the RFC iproute2 patch.

net/sched: flower: refactor control flag definitions

2024-07-15T16:14:37+00:00

Redefine the flower control flags as an enum, so they are included in BTF info. Make the kernel-side enum a more explicit superset of TCA_FLOWER_KEY_FLAGS_*, new flags still need to be added to both enums, but at least the bit position only has to be defined once. FLOW_DIS_ENCAPSULATION is never set for mask, so it can't be exposed to userspace in an unsupported flags mask error message, so it will be placed one bit position above the last uAPI flag.

net/sched: Retire ipt action

2024-01-02T12:41:16+00:00

The tc ipt action was intended to run all netfilter/iptables target. Unfortunately it has not benefitted over the years from proper updates when netfilter changes, and for that reason it has remained rudimentary. Pinging a bunch of people that i was aware were using this indicates that removing it wont affect them. Retire it to reduce maintenance efforts. Buh-bye.
