Functions ¶

func Build ¶

func Build(feedsDir string, feedNames []string) (map[string]*model.SetData, error)

Build loads all feed files and returns consolidated SetData This replaces the slow bash implementation with fast Go parsing

Performance: <2s for 50,000+ IPs (vs 45s in bash)

Features: - IPv4/IPv6 automatic separation - CIDR normalization - Comment and empty line filtering - Streaming parsing (memory efficient)

func IsCIDR ¶

func IsCIDR(s string) bool

IsCIDR checks if a string is a valid CIDR Delegates to netutil.IsCIDR for consistency

func IsIPv4 ¶

func IsIPv4(ipStr string) bool

IsIPv4 checks if an IP string is IPv4 Delegates to netutil.IsIPv4 for consistency

func IsIPv6 ¶

func IsIPv6(ipStr string) bool

IsIPv6 checks if an IP string is IPv6 Delegates to netutil.IsIPv6 for consistency

func ListAvailableFeeds ¶

func ListAvailableFeeds(feedsDir string) ([]string, error)

ListAvailableFeeds returns a list of all available feed names

func LoadFeed ¶

func LoadFeed(feedsDir, feedName string) (*model.SetData, error)

LoadFeed loads a single feed file and returns SetData

func LoadSpecificFeed ¶

func LoadSpecificFeed(feedsDir string, feedName string) ([]string, []string, []string, []string, error)

LoadSpecificFeed loads a single feed by name Returns IPv4 IPs, IPv6 IPs, IPv4 CIDRs, IPv6 CIDRs

func Merge ¶

func Merge(feeds map[string]*model.SetData) *model.SetData

Merge combines multiple SetData into one Useful for consolidating multiple feeds into a single nftables set

Types ¶

type FeedInfo ¶

type FeedInfo struct {
	Name        string
	FilePath    string
	IPv4Count   int
	IPv6Count   int
	LastUpdated string
}

FeedInfo represents metadata about a threat feed

func GetFeedStats ¶

func GetFeedStats(feedsDir string) ([]FeedInfo, error)

GetFeedStats returns statistics about all feeds

func LoadAllFeeds ¶

func LoadAllFeeds(feedsDir string) (map[string]bool, map[string]bool, map[string]bool, map[string]bool, []FeedInfo, error)

LoadAllFeeds loads all feed files from the feeds directory Returns IPv4 IPs, IPv6 IPs, IPv4 CIDRs, IPv6 CIDRs, and feed info

type ParsedEntry ¶

type ParsedEntry struct {
	IPv4   bool   // true if IPv4, false if IPv6
	IsCIDR bool   // true if CIDR range, false if single IP
	Value  string // normalized IP or CIDR
}

ParsedEntry represents a parsed feed line

func ParseFeedLine ¶

func ParseFeedLine(line string) (*ParsedEntry, error)

ParseFeedLine parses a single line from a feed/blacklist/whitelist file Handles multiple formats:

Plain IP: "1.2.3.4"
CIDR: "1.2.3.0/24"
With inline comment: "1.2.3.4 # some comment"
With whitespace-separated fields: "1.2.3.4 reason timestamp"

Returns nil, nil for empty lines and comments (skip) Returns nil, error for invalid IPs/CIDRs

func ParseFeedLineSilent ¶

func ParseFeedLineSilent(line string) *ParsedEntry

ParseFeedLineSilent parses a line and returns nil for both skip and error cases Use this when you want to silently ignore invalid entries (like the original loader)

func ParseFeedLineStrict ¶

func ParseFeedLineStrict(line string) (*ParsedEntry, error)

ParseFeedLineStrict is like ParseFeedLine but returns error for invalid entries Use this when you want to know about parsing failures
