2017-12-17packet/bgp: use strconv.FormatInt() instead of strconv.Itoa() in testsVincent Bernat
Itoa() takes an int which will only be 32-bit on i386 and similar architectures. In tests, some constants are too big. Therefore, switch all uses of strconv.Itoa() to strconv.FormatInt(). Without this change, we get: ``` src/github.com/osrg/gobgp/packet/bgp/bgp_test.go:1123:41: constant 2864434397 overflows int ```

2017-12-16table/policy: Support prefix representation in NeighborSetSatoshi Fujimoto
Currently, "neighbor-set" supports only IP address representation and IP prefix representation(such as "192.168.0.0/24") is not supported. This commit enables to accept the prefix representation for "neighbor-set" to allow neighbors to be specified as range. Signed-off-by: Satoshi Fujimoto <satoshi.fujimoto7@gmail.com>

2017-12-06packet/bgp: JSON encode of MP_UNREACH_NLRI attributeVincent Bernat
MP_REACH_NLRI was already correctly encoded in JSON, while this was not the case for MP_UNREACH_NLRI. Before: ```json "PathAttributes": [ { "type": 15, "value": "AAIBQCABDbgAEwAA" } ] ``` After: ```json "PathAttributes": [ { "type": 15, "afi": 2, "value": [ { "prefix": "2001:db8:8::/64" } ], "safi": 1 } ] ``` This commit also adds two tests not directly related to JSON encoding as I was first thinking the problem may be related to incorrect parsing of the path attribute.

2017-11-28packet/bgp: Use fixed len types in FlowSpec componentsIWASE Yusuke
Currently, the "FlowSpecComponentItem" uses int type for the "Op" and "Value" fields, but Golang int type has 4 bytes length on the 32-bit env and 8 bytes length on the 64-bit env. For example, to support the SNAP (Type 20) rule, which has 5 bytes value field, int type has not enough length on 32-bit env. This patch fixes to use the fixed length integer types for the FlowSpec components and avoid overflows of value range. Signed-off-by: IWASE Yusuke <iwase.yusuke0@gmail.com>
2017-11-27test/lib: Allow unconfigured peer-as for Unnumbered BGPSatoshi Fujimoto
For Unnumbered BGP, neighbor AS number isn't needed to be specified, so 'peer-as' should not be specified in the scenario test for Unnumbered BGP. However, currently 'peer-as' is always specified in test/lib/gobgp.py This commit solves this by not specifying `peer-as` if 'neighbor-interface' is configured.

This fixes the ae7e572550df919c1b9990da8787fc1e860bc20d commit regression. gobgp neighbor command takes a bogus neighbor name like the following: fujita@ubuntu:~/go/src/github.com/osrg/gobgp/gobgp$ ./gobgp n 1 BGP neighbor is 172.17.0.2, remote AS 65001 BGP version 4, remote router ID unknown BGP state = active, up for 17496d 14:21:50 BGP OutQ = 0, Flops = 0 Hold time is 0, keepalive interval is 0 seconds Configured hold time is 60, keepalive interval is 20 seconds Signed-off-by: FUJITA Tomonori <fujita.tomonori@lab.ntt.co.jp>

2017-11-24packet/bgp: Use regexp to parse FlowSpec rulesIWASE Yusuke
Currently, the parser for the string representation of FlowSpec rules splits the given string into characters and validates them character by character. So we need to handle the unexpected white spaces carefully. This patch introduces the regular expressions to parse the FlowSpec rules and simplify the parsers. Also improves robustness for the unexpectedly inserted white spaces like "& == tcp". Signed-off-by: IWASE Yusuke <iwase.yusuke0@gmail.com>

2017-11-24packet/bgp: Invert FlowSpec bitmask operand positionIWASE Yusuke
Currently, if the both NOT and MATCH bit are set for the FlowSpec bitmask operand, the string representation will be "=!". For the readability and the consistency with the representation of numeric operator, it should be "!=". This patch inverts "=!" into "!=" for the bitmask operand.
