  "message": "tipc: change socket buffer overflow control to respect sk_rcvbuf\n\nAs per feedback from the netdev community, we change the buffer\noverflow protection algorithm in receiving sockets so that it\nalways respects the nominal upper limit set in sk_rcvbuf.\n\nInstead of scaling up from a small sk_rcvbuf value, which leads to\nviolation of the configured sk_rcvbuf limit, we now calculate the\nweighted per-message limit by scaling down from a much bigger value,\nstill in the same field, according to the importance priority of the\nreceived message.\n\nTo allow for administrative tunability of the socket receive buffer\nsize, we create a tipc_rmem sysctl variable to allow the user to\nconfigure an even bigger value via sysctl command.  It is a size of\nthree (min/default/max) to be consistent with things like tcp_rmem.\n\nBy default, the value initialized in tipc_rmem[1] is equal to the\nreceive socket size needed by a TIPC_CRITICAL_IMPORTANCE message.\nThis value is also set as the default value of sk_rcvbuf.\n\nOriginally-by: Jon Maloy \u003cjon.maloy@ericsson.com\u003e\nCc: Neil Horman \u003cnhorman@tuxdriver.com\u003e\nCc: Jon Maloy \u003cjon.maloy@ericsson.com\u003e\n[Ying: added sysctl variation to Jon\u0027s original patch]\nSigned-off-by: Ying Xue \u003cying.xue@windriver.com\u003e\n[PG: don\u0027t compile sysctl.c if not config\u0027d; add Documentation]\nSigned-off-by: Paul Gortmaker \u003cpaul.gortmaker@windriver.com\u003e\nSigned-off-by: David S.
