Types

type BatchProvider

type BatchProvider struct {
	sync.Mutex
	// contains filtered or unexported fields
}

BatchProvider uses iptables-restore to program ACLs

func NewGoIPTablesProvider

func NewGoIPTablesProvider(batchTables []string) (*BatchProvider, error)

NewGoIPTablesProvider returns an IptablesProvider interface based on the go-iptables external package.

func (*BatchProvider) Append

func (b *BatchProvider) Append(table, chain string, rulespec ...string) error

Append will append the provided rule to the local cache or call directly the iptables command depending on the table.

func (*BatchProvider) ClearChain

func (b *BatchProvider) ClearChain(table, chain string) error

ClearChain will clear the chains.

func (*BatchProvider) Commit

func (b *BatchProvider) Commit() error

Commit commits the rules to the system

func (*BatchProvider) Delete

func (b *BatchProvider) Delete(table, chain string, rulespec ...string) error

Delete will delete the rule from the local cache or the system.

func (*BatchProvider) DeleteChain

func (b *BatchProvider) DeleteChain(table, chain string) error

DeleteChain will delete the chains.

func (*BatchProvider) Insert

func (b *BatchProvider) Insert(table, chain string, pos int, rulespec ...string) error

Insert will insert the rule in the corresponding position in the local cache or call the corresponding iptables command, depending on the table.

func (*BatchProvider) ListChains

func (b *BatchProvider) ListChains(table string) ([]string, error)

ListChains will provide a list of the current chains.

func (*BatchProvider) NewChain

func (b *BatchProvider) NewChain(table, chain string) error

NewChain creates a new chain.

type Ipset

type Ipset interface {
	Add(entry string, timeout int) error
	AddOption(entry string, option string, timeout int) error
	Del(entry string) error
	Destroy() error
	Flush() error
	Test(entry string) (bool, error)
}

Ipset is an abstraction of all the methods an implementation of userspace ipsets need to provide.

type IpsetProvider

type IpsetProvider interface {
	NewIpset(name string, hasht string, p *ipset.Params) (Ipset, error)
	DestroyAll() error
}

IpsetProvider returns a fabric for Ipset.

func NewGoIPsetProvider

func NewGoIPsetProvider() IpsetProvider

NewGoIPsetProvider Return a Go IPSet Provider

type IptablesProvider

type IptablesProvider interface {
	// Append apends a rule to chain of table
	Append(table, chain string, rulespec ...string) error
	// Insert inserts a rule to a chain of table at the required pos
	Insert(table, chain string, pos int, rulespec ...string) error
	// Delete deletes a rule of a chain in the given table
	Delete(table, chain string, rulespec ...string) error
	// ListChains lists all the chains associated with a table
	ListChains(table string) ([]string, error)
	// ClearChain clears a chain in a table
	ClearChain(table, chain string) error
	// DeleteChain deletes a chain in the table. There should be no references to this chain
	DeleteChain(table, chain string) error
	// NewChain creates a new chain
	NewChain(table, chain string) error
	// Commit will commit changes if it is a batch provider.
	Commit() error
}

IptablesProvider is an abstraction of all the methods an implementation of userspace iptables need to provide.

type TestIpset interface {
	Ipset
	MockAdd(t *testing.T, impl func(entry string, timeout int) error)
	MockAddOption(t *testing.T, impl func(entry string, option string, timeout int) error)
