  "message": "dccp ccid-2: Separate option parsing from CCID processing\n\nThis patch replaces an almost identical replication of code: large parts\nof dccp_parse_options() re-appeared as ccid2_ackvector() in ccid2.c.\n\nApart from the duplication, this caused two more problems:\n 1. CCIDs should not need to be concerned with parsing header options;\n 2. one can not assume that Ack Vectors appear as a contiguous area within an\n    skb, it is legal to insert other options and/or padding in between. The\n    current code would throw an error and stop reading in such a case.\n\nThe patch provides a new data structure and associated list housekeeping.\n\nOnly small changes were necessary to integrate with CCID-2: data structure\ninitialisation, adapt list traversal routine, and add call to the provided\ncleanup routine.\n\nThe latter also lead to fixing the following BUG: CCID-2 so far ignored\nAck Vectors on all packets other than Ack/DataAck, which is incorrect,\nsince Ack Vectors can be present on any packet that has an Ack field.\n\nDetails:\n--------\n * received Ack Vectors are parsed by dccp_parse_options() alone, which passes\n   the result on to the CCID-specific routine ccid_hc_tx_parse_options();\n * CCIDs interested in using/decoding Ack Vector information will add code\n   to fetch parsed Ack Vectors via this interface;\n * a data structure, `struct dccp_ackvec_parsed\u0027 is provided as interface;\n * this structure arranges Ack Vectors of the same skb into a FIFO order;\n * a doubly-linked list is used to keep the required FIFO code small.\n\nSigned-off-by: Gerrit Renker \u003cgerrit@erg.abdn.ac.uk\u003e\n",
