func ParseAddress ¶

func ParseAddress(s string) (net.IP, uint16, error)

ParseAddress parses a string, e.g.,Akihiro Suda, 10 months ago: • initial commit "0100007F:0050" (127.0.0.1:80) "000080FE00000000FF57A6705DC771FE:0050" ([fe80::70a6:57ff:fe71:c75d]:80) "00000000000000000000000000000000:0050" (0.0.0.0:80)

See https://serverfault.com/questions/592574/why-does-proc-net-tcp6-represents-1-as-1000

ParseAddress parses the entry using the current host's native byte order. Use ParseAddressWithByteOrder to parse an entry whose byte order is known. The parsing logic is derived from the lima project in https://github.com/lima-vm/lima/blob/v0.8.3/pkg/guestagent/procnettcp/procnettcp.go#L95-L137 and is licensed under the Apache License, Version 2.0

func ParseAddressWithByteOrder ¶

func ParseAddressWithByteOrder(s string, order binary.ByteOrder) (net.IP, uint16, error)

ParseAddressWithByteOrder is like ParseAddress but takes the byte order of the /proc data explicitly. The kernel writes each 4-byte group of the address in the host's native byte order (little-endian on x86/arm64, big-endian on s390x), so each group is read with that order and rewritten in network order to build the net.IP.
