NvRedfishClientPool::create_bmc built the BMC base URL with bare format!s and then .expect()ed Url::parse. IPv6 hosts were left unbracketed, so an IPv6 BMC produced an invalid authority such as https://2001:db8::1:8443 -- which Url::parse rejects, panicking the caller. This mirrors the bracketing the health crate's BmcAddr::to_url already applies on its own path. Extract a testable build_bmc_url helper that brackets IPv6 literals in every arm: the port-only proxy path uses the BMC's own IpAddr, and the host / host+port proxy paths bracket config-supplied IPv6 literals. The no-override arm is unchanged -- SocketAddr's Display already brackets. Add unit tests covering each arm; the port-only IPv6 case fails before this change. Part of the NVIDIA#2237 IPv6 bug bucket; addresses the Redfish-bracket item of NVIDIA#2406. Signed-off-by: Omar Refai <omar@refai.org>

There was a problem hiding this comment.
This code doesn't look right. Probably HostPortPair should be able to destinguish IPv6 address from Hostname or return url_host(). This code here looks like patch on wrong / missing behavior of other object.
Could you please move this function there to make incoherent design of HostAndPort more local?

NvRedfishClientPool::create_bmcbuilds the BMC base URL with bareformat!s and then.expect()sUrl::parse. IPv6 hosts were left unbracketed, so an IPv6 BMC produced an invalid authority such ashttps://2001:db8::1:8443— whichUrl::parserejects, panicking the caller.The codebase already brackets IPv6 on the sibling path (
crates/health/src/endpoint/model.rs::BmcAddr::to_url); thenv_redfishpool was missing the same handling.This extracts a small, testable
build_bmc_urlhelper that brackets IPv6 literals in every arm:IpAddr(the panicking case),SocketAddr'sDisplayalready brackets.Hostnames, IPv4 literals, and already-bracketed hosts are passed through untouched.

Testing
cargo test -p carbide-redfish --features test-support nv_redfish::tests— 5 passing, covering each arm. The newport_only_proxy_brackets_ipv6_bmctest fails before this change (produceshttps://2001:db8::1:8443, asserted against the bracketedhttps://[2001:db8::1]:8443).cargo clippy -- -D warningsandcargo fmt --checkboth clean.Additional Notes
The
libredfishproxy path (crates/redfish/src/libredfish/implementation.rs) constructs its endpoint inside the externallibredfishcrate and is out of scope here.
