configd code design

Overview

The configd package is written in Go. It provides functionality to parse, compile and validate Yang schemas, and to validate base configurations and configuration updates against those schemas. Further to this it manages the configuration change process (set/delete, commit etc).

Much of the subsidiary functionality, eg the YANG compiler and handling for configd YANG extensions, is implemented in separate repositories.

Packages in this repository

The following packages are included in this repository.

Yang cmds

yang2path
yang2rev
yangc - standalone version of YANG compiler (inc cfgd xtns)
yanggraph

Configd cmds

args2cpath
callrpc
cfgcli - implements 'config' mode commands
cfgdiff
cfgparse
cfgread
configd - configd process (parses YANG, config, runs sessions)
configdcaps
featcaps
gettree
normalize

Configd packages

configd (configd) - authentication, logging, error formatting
commit (configd/commit) - builds config trees for commit
session (configd/session) - session management
server (configd/server) - server for incoming RPCs

Functions ¶

func InSecretsGroup ¶

func InSecretsGroup(ctx *Context) bool

func NewLogger ¶

func NewLogger(p syslog.Priority, logFlag int) (*log.Logger, error)

version of syslog.NewLogger which uses base program name as logging tag

Types ¶

type Config ¶

type Config struct {
	User         string
	Runfile      string
	Logfile      string
	Pidfile      string
	Yangdir      string
	Socket       string
	SecretsGroup string
	SuperGroup   string
	Capabilities string
}

type Context ¶

type Context struct {
	Configd   bool
	Auth      auth.Auther
	Pid       int32
	Uid       uint32
	User      string
	UserHome  string
	Groups    []string
	Superuser bool
	Config    *Config
	Dlog      *log.Logger
	Elog      *log.Logger
	Wlog      *log.Logger
	CompMgr   schema.ComponentManager
	Noexec    bool
}

func (*Context) DropPrivileges ¶

func (c *Context) DropPrivileges()

func (*Context) RaisePrivileges ¶

func (c *Context) RaisePrivileges()

Raising privileges should be done sparingly as it bypasses things like ACM, secret redaction etc. however it is occasionally necessary.

type LockId ¶

type LockId int32

const (
	COMMIT LockId = -1
	SYSTEM LockId = -2
)

func (LockId) String ¶

func (l LockId) String() string
