2014-01-22bonding: convert mode setting to use the new option APINikolay Aleksandrov
This patch makes the bond's mode setting use the new option API and adds support for dependency printing which relies on having an entry for the mode option in the bond_opts[] array. Also add the ability to print the mode name when mode dependency fails and fix some trivial/style errors. Signed-off-by: Nikolay Aleksandrov <nikolay@redhat.com> Signed-off-by: David S.

2014-01-22bonding: add infrastructure for an option APINikolay Aleksandrov
This patch adds the necessary basic infrastructure to support centralized and unified option manipulation API for the bonding. The new structure bond_option will be used to describe each option with its dependencies on modes which will be checked automatically thus removing a lot of duplicated code. Also automatic range checking is added for some options. Currently the option setting function requires RTNL to be acquired prior to calling it, since many options already rely on RTNL it seemed like the best choice to protect all against common race conditions. In order to add an option the following steps need to be done: 1. Add an entry BOND_OPT_<option> to bond_options.h so it gets a unique id and a bit corresponding to the id 2. Add a bond_option entry to the bond_opts[] array in bond_options.c which describes the option, its dependencies and its manipulation function 3. Add code to export the option through sysfs and/or as a module parameter (the sysfs export will be made automatically in the future) The options can have different flags set, currently the following are supported: BOND_OPTFLAG_NOSLAVES - require that the bond device has no slaves prior to setting the option BOND_OPTFLAG_IFDOWN - require that the bond device is down prior to setting the option BOND_OPTFLAG_RAWVAL - don't parse the value but return it raw for the option to parse There's a new value structure to describe different types of values which can have the following flags: BOND_VALFLAG_DEFAULT - marks the default option (permanent string alias to this option is "default") BOND_VALFLAG_MIN - the minimum value that this option can have BOND_VALFLAG_MAX - the maximum value that this option can have An example would be nice here, so if we have an option which can have the values "off"(2), "special"(4, default) and supports a range, say 16 - 32, it should be defined as follows: "off", 2, "special", 4, BOND_VALFLAG_DEFAULT, "rangemin", 16, BOND_VALFLAG_MIN, "rangemax", 32, BOND_VALFLAG_MAX So we have the valid intervals: [2, 2], [4, 4], [16, 32] Also the valid strings: "off" = 2, "special" and "default" = 4 "rangemin" = 16, "rangemax" = 32 BOND_VALFLAG_(MIN|MAX) can be used to specify a valid range for an option, if MIN is omitted then 0 is considered as a minimum. If an exact match is found in the values[] table it will be returned, otherwise the range is tried (if available). The option parameter passing is done by using a special structure called bond_opt_value which can take either a string or a value to parse. One of the bond_opt_init(val|str) macros should be used depending on which one does the user want to parse (string or value). Then a call to __bond_opt_set should be done under RTNL.

2014-01-21reciprocal_divide: update/correction of the algorithmHannes Frederic Sowa
Jakub Zawadzki noticed that some divisions by reciprocal_divide() were not correct [1][2], which he could also show with BPF code after divisions are transformed into reciprocal_value() for runtime invariance which can be passed to reciprocal_divide() later on; reverse in BPF dump ended up with a different, off-by-one K in some situations. This has been fixed by Eric Dumazet in commit aee636c4809fa5 ("bpf: do not use reciprocal divide"). This follow-up patch improves reciprocal_value() and reciprocal_divide() to work in all cases by using Granlund and Montgomery method, so that also future use is safe and without any non-obvious side-effects. Known problems with the old implementation were that division by 1 always returned 0 and some off-by-ones when the dividend and divisor where very large. This seemed to not be problematic with its current users, as far as we can tell. Eric Dumazet checked for the slab usage, we cannot surely say so in the case of flex_array. Still, in order to fix that, we propose an extension from the original implementation from commit 6a2d7a955d8d resp. [3][4], by using the algorithm proposed in "Division by Invariant Integers Using Multiplication" [5], Torbjörn Granlund and Peter L. Montgomery, that is, pseudocode for q = n/d where q, n, d is in u32 universe: 1) Initialization: int l = ceil(log_2 d) uword m' = floor((1<<32)*((1<<l)-d)/d)+1 int sh_1 = min(l,1) int sh_2 = max(l-1,0) 2) For q = n/d, all uword: uword t = (n*m')>>32 q = (t+((n-t)>>sh_1))>>sh_2 The assembler implementation from Agner Fog [6] also helped a lot while implementing. We have tested the implementation on x86_64, ppc64, i686, s390x; on x86_64/haswell we're still half the latency compared to normal divide. Joint work with Daniel Borkmann.

2013-12-11ipv4: fix wildcard search with inet_confirm_addr()Nicolas Dichtel
Help of this function says: "in_dev: only on this interface, 0=any interface", but since commit 39a6d0630012 ("[NETNS]: Process inet_confirm_addr in the correct namespace."), the code supposes that it will never be NULL. This function is never called with in_dev == NULL, but it's exported and may be used by an external module. Because this patch restore the ability to call inet_confirm_addr() with in_dev == NULL, I partially revert the above commit, as suggested by Julian.

2013-11-28bonding: disable arp and enable mii monitoring when bond change to no uses ↵dingtianhong
arp mode Because the ARP monitoring is not support for 802.3ad, but I still could change the mode to 802.3ad from ab mode while ARP monitoring is running, it is incorrect. So add a check for 802.3ad in bonding_store_mode to fix the problem, and make a new macro BOND_NO_USES_ARP() to simplify the code. v2: according to the Dan Williams's suggestion, bond mode is the most important bond option, it should override any of the other sub-options. So when the mode is changed, the conficting values should be cleared or reset, otherwise the user has to duplicate more operations to modify the logic. I disable the arp and enable mii monitoring when the bond mode is changed to AB, TB and 8023AD if the arp interval is true. v3: according to the Nik's suggestion, the default value of miimon should need a name, there is several place to use it, and the bond_store_arp_interval() could use micro BOND_NO_USES_ARP to make the code more simpify.

2013-10-03bonding: modify the old and add new xmit hash policiesNikolay Aleksandrov
This patch adds two new hash policy modes which use skb_flow_dissect: 3 - Encapsulated layer 2+3 4 - Encapsulated layer 3+4 There should be a good improvement for tunnel users in those modes. It also changes the old hash functions to: hash ^= (__force u32)flow.dst ^ (__force u32)flow.src; hash ^= (hash >> 16); hash ^= (hash >> 8); Where hash will be initialized either to L2 hash, that is SRCMAC[5] XOR DSTMAC[5], or to flow->ports which should be extracted from the upper layer. Flow's dst and src are also extracted based on the xmit policy either directly from the buffer or by using skb_flow_dissect, but in both cases if the protocol is IPv6 then dst and src are obtained by ipv6_addr_hash() on the real addresses. In case of a non-dissectable packet, the algorithms fall back to L2 hashing. The bond_set_mode_ops() function is now obsolete and thus deleted because it was used only to set the proper hash policy. Also we trim a pointer from struct bonding because we no longer need to keep the hash function, now there's only a single hash function - bond_xmit_hash that works based on bond->params.xmit_policy. The hash function and skb_flow_dissect were suggested by Eric Dumazet. The layer names were suggested by Andy Gospodarek, because I suck at semantics.

2013-09-26bonding: convert first/last slave logic to use neighboursVeaceslav Falico
For that, use netdev_adjacent_get_private(list_head) on bond's lower neighbour list members. Also, add a small macro - bond_slave_list(bond), which returns the bond list via neighbour list.
