| Summary | 0003858: link::bind-ip in 1.2.3.4 style breaks links on IPv6-enabled build | ||||
| Description | Using (unmodified) 3.2.8.1 After reading the Changelog (- 0003163: [ircd] Allow 1.2.3.4 style IPs in IPv6 mode (not only ::ffff:1.2.3.4)), I decided to edit my config file and use classic IPv4 style. This caused the IPv4 link to fail with "Operation not permitted". I determined the culprit to be link::bind-ip. Note that setting link::hostname with 1.2.3.4 notation is not enough to reproduce the problem. In other words, at the moment, it is OK to use the standard IPv4 notation for anything *but* link::bind-ip. | ||||
| Steps To Reproduce | - Build 3.2.8 (or 3.2.8.1) with IPv6 support - Create an IPv4 link block with link::bind-ip in 1.2.3.4 style - Start ircd and attempt to link | ||||
| Additional Information | When attempting to link, the ircd is actually binding on an available IPv6 address instead of an IPv4 one, which causes the subsequent connect() to fail. Good : bind(10, {sa_family=AF_INET6, sin6_port=htons(0), inet_pton(AF_INET6, "::ffff:1.2.3.4", &sin6_addr), sin6_flowinfo=0, sin6_scope_id=0}, 28) = 0 (...) connect(10, {sa_family=AF_INET6, sin6_port=htons(6602), inet_pton(AF_INET6, "::ffff:5.6.7.8", &sin6_addr), sin6_flowinfo=0, sin6_scope_id=0}, 28) = -1 EINPROGRESS (Operation now in progress) Bad : bind(10, {sa_family=AF_INET6, sin6_port=htons(0), inet_pton(AF_INET6, "2001:my:v6::here", &sin6_addr), sin6_flowinfo=0, sin6_scope_id=0}, 28) = 0 (...) connect(10, {sa_family=AF_INET6, sin6_port=htons(6602), inet_pton(AF_INET6, "::ffff:5.6.7.8", &sin6_addr), sin6_flowinfo=0, sin6_scope_id=0}, 28) = -1 EPERM (Operation not permitted) | ||||

Fixed in .770, thanks for the report. - Fixed IPv4 ip's in link::bind-ip on IPv6 builds. This caused issues ranging from not binding to that ip when linking, to not being able to link at all. Also fixed a very small memory leak upon /REHASH. Bug reported by Mr_Smoke (0003858). |
