* link_addr: be more strict about address formatsLexi Winter2025-05-152-80/+152
| | | | | | | | | | | | | | | | | | | | | | instead of accepting any character as a delimiter, only accept ':', '.' and '-', and only permit a single delimiter in an address. this prevents accepting bizarre addresses like: ifconfig epair2a link 10.1.2.200/28 ... which is particularly problematic on an INET6-only system, in which case ifconfig defaults to the 'link' family, meaning that: ifconfig epair2a 10.1.2.200/28 ... changes the Ethernet address of the interface. bump __FreeBSD_version so link_addr() consumers can detect the change.

* nsswitch.conf: Avoid modification after installationMark Johnston2025-04-071-4/+8
| | | | | | | | | | | | | | | | | | | | | To implement WITHOUT_NIS, we have a hack in the build which modifies the installed nsswitch.conf to remove NIS compat providers and databases. This hack operates on the installed nsswitch.conf, which means that the installed file size won't match that listed in the metalog. One option would be to maintain two copies of nsswitch.conf, one for each configuration, but that would result in duplication and I don't see a clear way around that. Instead, stage a copy of nsswitch.conf in the libc objdir, and modify that one before installing, so that the version recorded in the metalog matches what actually gets installed.

* libc/getaddrinfo(2): return EAI_AGAIN on nameserver timeoutGleb Smirnoff2025-03-281-15/+43
| | | | | | | | | | | | | A nameserver timeout is a soft failure, future attempts may succeed. Returning EAI_AGAIN is crucial for API users to tell a soft name resolution failure from negative resolution result. Before the change we would return EAI_ADDRFAMILY, which I believe, is a regression from 144361386696, and before that revision we used to return EAI_NONAME in most of the cases.

* libc/getnameinfo: stop adding NI_NUMERICHOST where inappropriateBjoern A. Zeeb2024-07-261-17/+37
| | | | | | | | | | | | | | | | | | | | | | | | Checking the first nibble of the IPv6 address to be 0 and then excluding two well known cases (v4-mapped, loopback) leaves us with more cases where the first nibble could be 0, e.g., the RFC 6052, 2.1 Well-Known Prefix 64:ff9b::/96. It is not practical to track them all and it is not clear what lead to this special casing originally, so remove them. While here also remove the IN6_IS_ADDR_LINKLOCAL() + NI_NUMERICHOST case as link-local address resolution does exist. We do leave the IN6_IS_ADDR_MULTICAST() case for now as I could not find any references to any official reverse lookups for these. Adding comments for more case (and some historic behaviour) in order to make it easier to follow the logic.

This is implemented via an added error in the nsswitch layer, NS_ADDRFAMILY, which is used only by getaddrinfo(). The error is passed through nsdispatch(3), but that routine has no changes to handle this error. The error originates in the getaddrinfo DNS layer called via nsdispatch(), and is processed by the search layer that calls nsdispatch().
