This avoids masking low-resolution errors.\n Instead, the code now checks against real boundaries (implemented by preceding\n patch) and provides warnings whenever a real value falls below the threshold.\n\n If such messages are observed, it is a better solution to take this as an\n indication that the lookup table needs to be re-engineered.\n\nChangelog:\n----------\n This patch\n * makes handling all TFRC resolution errors local to the TFRC library\n\n * removes unnecessary test whether X_calc is \u0027infinity\u0027 due to p\u003d\u003d0 -- this\n condition is already caught by tfrc_calc_x()\n\n * removes setting ccid3hctx_p \u003d TFRC_SMALLEST_P in ccid3_hc_tx_packet_recv\n since this is now done by the TFRC library\n\n * updates BUG_ON test in ccid3_hc_tx_no_feedback_timer to take into account\n that p now is either 0 (and then X_calc is irrelevant), or it is \u003e 0; since\n the handling of TFRC_SMALLEST_P is now taken care of in the tfrc library\n\nJustification:\n--------------\n The TFRC code uses a lookup table which has a bounded resolution.\n The lowest possible value of the loss event rate `p\u0027 which can be\n resolved is currently 0.0001. Substituting this lower threshold for\n p when p is less than 0.0001 results in a huge, exponentially-growing\n error. The error can be computed by the following formula:\n\n (f(0.0001) - f(p))/f(p) * 100 for p \u003c 0.0001\n\n Currently the solution is to use an (arbitrary) value\n TFRC_SMALLEST_P \u003d 40 * 1E-6 \u003d 0.00004\n and to consider all values below this value as `virtually zero\u0027. Due to\n the exponentially growing resolution error, this is not a good idea, since\n it hides the fact that the table can not resolve practically occurring cases.\n Already at p \u003d\u003d TFRC_SMALLEST_P, the error is as high as 58.19%!\n\nSigned-off-by: Gerrit Renker \u003cgerrit@erg.abdn.ac.uk\u003e\nAcked-by: Ian McDonald \u003cian.mcdonald@jandi.co.nz\u003e\nSigned-off-by: Arnaldo Carvalho de Melo \u003cacme@mandriva.com\u003e\n" }, { "commit": "006042d7e1a0aae35c9dd9eb8ec71fa379679adb", "tree": "e0f7a4f351fbf147bd452ff45061245fd985f27d", "parents": [ "8d0086adac0041de66b5f41b77eec0d8d239e16c" ], "author": { "name": "Gerrit Renker", "email": "gerrit@erg.abdn.ac.uk", "time": "Sun Dec 03 14:52:41 2006 -0200" }, "committer": { "name": "Arnaldo Carvalho de Melo", "email": "acme@mandriva.com", "time": "Sun Dec 03 14:52:41 2006 -0200" }, "message": "[DCCP] tfrc: Identify TFRC table limits and simplify code\n\nThis\n * adds documentation about the lowest resolution that is possible within\n the bounds of the current lookup table\n * defines a constant TFRC_SMALLEST_P which defines this resolution\n * issues a warning if a given value of p is below resolution\n * combines two previously adjacent if-blocks of nearly identical\n structure into one\n\nThis patch does not change the algorithm as such.\n\nSigned-off-by: Gerrit Renker \u003cgerrit@erg.abdn.ac.uk\u003e\nAcked-by: Ian McDonald \u003cian.mcdonald@jandi.co.nz\u003e\nSigned-off-by: Arnaldo Carvalho de Melo \u003cacme@mandriva.com\u003e\n" }, { "commit": "8d0086adac0041de66b5f41b77eec0d8d239e16c", "tree": "9830f9188a9ba57bf75c0fa7c2246866f8a8789a", "parents": [ "90fb0e60dd9178dbca2e42c682c483cdb7ea9f2d" ], "author": { "name": "Gerrit Renker", "email": "gerrit@erg.abdn.ac.uk", "time": "Sun Dec 03 14:52:26 2006 -0200" }, "committer": { "name": "Arnaldo Carvalho de Melo", "email": "acme@mandriva.com", "time": "Sun Dec 03 14:52:26 2006 -0200" }, "message": "[DCCP] tfrc: Add protection against invalid parameters to TFRC routines\n\n 1) For the forward X_calc lookup, it\n * protects effectively against RTT\u003d0 (this case is possible), by\n returning the maximal lookup value instead of just setting it to 1\n * reformulates the array-bounds exceeded condition: this only happens\n if p is greater than 1E6 (due to the scaling)\n * the case of negative indices can now with certainty be excluded,\n since documentation shows that the formulas are within bounds\n * additional protection against p \u003d 0 (would give divide-by-zero)\n\n 2) For the reverse lookup, it warns against\n * protects against exceeding array bounds\n * now returns 0 if f(p) \u003d 0, due to function definition\n * warns about minimal resolution error and returns the smallest table\n value instead of p\u003d0 [this would mask congestion conditions]\n\nSigned-off-by: Gerrit Renker \u003cgerrit@erg.abdn.ac.uk\u003e\nAcked-by: Ian McDonald \u003cian.mcdonald@jandi.co.nz\u003e\nSigned-off-by: Arnaldo Carvalho de Melo \u003cacme@mandriva.com\u003e\n" }, { "commit": "90fb0e60dd9178dbca2e42c682c483cdb7ea9f2d", "tree": "09e750ded7fb3b34a0b146ef96a03a9495a9c37f", "parents": [ "50ab46c790a3408c441ba4c2faa9555cacc20028" ], "author": { "name": "Gerrit Renker", "email": "gerrit@erg.abdn.ac.uk", "time": "Sun Dec 03 14:52:01 2006 -0200" }, "committer": { "name": "Arnaldo Carvalho de Melo", "email": "acme@mandriva.com", "time": "Sun Dec 03 14:52:01 2006 -0200" }, "message": "[DCCP] tfrc: Fix small error in reverse lookup of p for given f(p)\n\nThis fixes the following small error in tfrc_calc_x_reverse_lookup.\n\n 1) The table is generated by the following equations:\n\tlookup[index][0] \u003d g((index+1) * 1000000/TFRC_CALC_X_ARRSIZE);\n\tlookup[index][1] \u003d g((index+1) * TFRC_CALC_X_SPLIT/TFRC_CALC_X_ARRSIZE);\n where g(q) is 1E6 * f(q/1E6)\n\n 2) The reverse lookup assigns an entry in lookup[index][small]\n\n 3) This index needs to match the above, i.e.\n * if small\u003d0 then\n\n \t\tp \u003d (index + 1) * 1000000/TFRC_CALC_X_ARRSIZE\n\n * if small\u003d1 then\n\n\t\tp \u003d (index+1) * TFRC_CALC_X_SPLIT/TFRC_CALC_X_ARRSIZE\n\nThese are exactly the changes that the patch makes;

Apart\nfrom the mentioned oops, I observed another one one, triggered at irregular\nintervals via timer interrupt:\n\n run_timer_softirq -\u003e dccp_keepalive_timer\n -\u003e inet_csk_reqsk_queue_prune\n -\u003e reqsk_free\n -\u003e dccp_v6_reqsk_destructor\n\nThe latter function is the problem and is also the last function to be called\nin said kernel panic.\n\nIn any case, there is a real problem with allocating the right request_sock\nwhich is what this patch tackles.\n\nIt fixes the following problem:\n - application listens on PF_INET6\n - DCCPv4 packet comes in, is handed over to dccp_v4_do_rcv, from there\n to dccp_v4_conn_request\n\nNow: socket is PF_INET6, packet is IPv4. The following code then furnishes the\nconnection with IPv6 - request_sock operations:\n\n req \u003d reqsk_alloc(sk-\u003esk_prot-\u003ersk_prot);\n\nThe first problem is that all further incoming packets will get a Reset since\nthe connection can not be looked up.\n\nThe second problem is worse:\n --\u003e reqsk_alloc is called instead of inet6_reqsk_alloc\n --\u003e consequently inet6_rsk_offset is never set (dangling pointer)\n --\u003e the request_sock_ops are nevertheless still dccp6_request_ops\n --\u003e destructor is called via reqsk_free\n --\u003e dccp_v6_reqsk_destructor tries to free random memory location (inet6_rsk_offset not set)\n --\u003e panic\n\nI have tested this for a while, DCCP sockets are now handled correctly in all\nthree scenarios (v4/v6 only/v4-mapped).\n\nCommiter note: I\u0027ve added the dccp_request_sock_ops forward declaration to keep\n the tree building and to reduce the size of the patch for 2.6.19,\n later I\u0027ll move the functions to the top of the affected source\n code to match what we have in the TCP counterpart, where this\n problem hasn\u0027t existed in the first place, dumb me not to have\n done the same thing on DCCP land 8)\n\nSigned-off-by: Gerrit Renker \u003cgerrit@erg.abdn.ac.uk\u003e\nSigned-off-by: Arnaldo Carvalho de Melo \u003cacme@mandriva.com\u003e\n" }, { "commit": "9469c7b4aa210ce94c6e7208cfadbd0aca0ebe08", "tree": "3461046e3c0a63577dc26d70246bac6892fe342c", "parents": [ "496c98dff8e353880299168d36fa082d6fba5237" ], "author": { "name": "YOSHIFUJI Hideaki", "email": "yoshfuji@linux-ipv6.org", "time": "Tue Oct 10 19:41:46 2006 -0700" }, "committer": { "name": "David S.
