Miroslav Lichvar says: ==================== Extend socket timestamping API Changes v5->v6: - fixed skb_is_swtx_tstamp() when OPT_TX_SWHW is disabled and improved its description - improved OPT_PKTINFO documentation - improved scm_timestamping documentation Changes v4->v5: - fixed initialization of reserved fields in struct scm_ts_pktinfo Changes v3->v4: - added reserved fields to struct scm_ts_pktinfo - replaced patch fixing false SW timestamps with a documentation fix - updated OPT_TX_SWHW patch to handle false SW timestamps Changes v2->v3: - modified struct scm_ts_pktinfo to use fixed-width integer types - added WARN_ON_ONCE for missing RCU lock in dev_get_by_napi_id() - modified dev_get_by_napi_id() to not return dev in unexpected branch - modified recv to return SCM_TIMESTAMPING_PKTINFO even if the interface index is unknown Changes v1->v2: - added separate patch for new NAPI functions - split code from __sock_recv_timestamp() for better readability - fixed RCU locking - fixed compiler warning (missing case in switch in first patch) - inline sw_tx_timestamp() in its only user Changes RFC->v1: - reworked SOF_TIMESTAMPING_OPT_PKTINFO patch to not add new fields to skb shared info (net device is now looked up by napi_id), not require any changes in drivers, and restrict the cmsg to incoming packets - renamed SOF_TIMESTAMPING_OPT_MULTIMSG to SOF_TIMESTAMPING_OPT_TX_SWHW and fixed its description - moved struct scm_ts_pktinfo from errqueue.h to net_tstamp.h as it can't be received from the error queue anymore - improved commit descriptions and removed incorrect comment This patchset adds new options to the timestamping API that will be useful for NTP implementations and possibly other applications. The first patch specifies a timestamp filter for NTP packets. The second patch updates drivers that can timestamp all packets, or need to list the filter as unsupported. There is no attempt to add the support to the phyter driver. The third patch adds two helper functions working with NAPI ID, which is needed by the next patch. The fourth patch adds a new option to get a new control message with the L2 length and interface index for incoming packets with hardware timestamps. The fifth patch fixes documentation on number of non-zero fields in scm_timestamping and warns about false software timestamps when SO_TIMESTAMP(NS) is combined with SCM_TIMESTAMPING. The sixth patch adds a new option to request both software and hardware timestamps for outgoing packets. The seventh patch updates drivers that assumed software timestamping cannot be used together with hardware timestamping. The patches have been tested on x86_64 machines with igb and e1000e drivers. ==================== Signed-off-by: David S. Miller <davem@davemloft.net> |

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
