Introduction

Compile ff tools

make

Install ff tools, all ff tools will be installed to /usr/local/bin/f-stack/, and some soft link will be created in /usr/local/bin, such as ff_top,ff_traffic, etc.

make install

Directory compat implements an ipc library using dpdk rte_ring and ports some source files compatible with FreeBSD and Linux.

Directory sbin contains all the tools binary that compiled.

All other directories are useful tools ported from FreeBSD. Since F-Stack is multi-process architecture and every process has an independent stack, so we must communicate with every F-Stack process. Each tool add an option -p(Which F-Stack process to communicate with, default 0), except that, it is same with the original FreeBSD.

Note that these tools must be executed serially.

sysctl

Usage:

sysctl -p <f-stack proc_id> [-bdehiNnoqTtWx] [ -B <bufsize> ] [-f filename] name[=value] ...
sysctl -p <f-stack proc_id> [-bdehNnoqTtWx] [ -B <bufsize> ] -a

For more details, see Manual page.

ifconfig

Usage:

ifconfig -p <f-stack proc_id> [-f type:format] %sinterface address_family
        [address [dest_address]] [parameters]
    ifconfig -p <f-stack proc_id> interface create
    ifconfig -p <f-stack proc_id> -a %s[-d] [-m] [-u] [-v] [address_family]
    ifconfig -p <f-stack proc_id> -l [-d] [-u] [address_family]
    ifconfig -p <f-stack proc_id> %s[-d] [-m] [-u] [-v]

We has supportted inet6, you can config ipv6 address like this:

ifconfig -p <f-stack proc_id> interface inet6 <ipv6 address> autoconf

Unsupported interfaces or parameters:

MAC(Mandatory Access Control)
media
SFP/SFP+
IEEE80211 Wireless
pfsync
LAGG LACP
jail

For more details, see Manual page.

route

Usage:

route -p <f-stack proc_id> [-46dnqtv] command [[modifiers] args]

Examples:

     Add a default route:

       ./sbin/route -p 0 add -net 0.0.0.0/0 192.168.1.1

     A shorter version of adding a default route can also be written as:

       ./sbin/route -p 0 add default 192.168.1.1

     Add a static route to the 172.16.10.0/24 network via the 172.16.1.1 gate-
     way:

       ./sbin/route -p 0 add -net 172.16.10.0/24 172.16.1.1

     Change the gateway of an already established static route in the routing
     table:

       ./sbin/route -p 0 change -net 172.16.10.0/24 172.16.1.2

     Display the route for a destination network:

       ./sbin/route -p 0 show 172.16.10.0
       ./sbin/route -p 0 -6 show ::/0

     Delete a static route from the routing table:

       ./sbin/route -p 0 delete -net 172.16.10.0/24 172.16.1.2

     Remove all routes from the routing table:

       ./sbin/route -p 0 flush

    FreeBSD uses `netstat -rn ` to list the route table which we havn't ported,
    you can execute the following command instead, `-d` means debug mode, `-v`
    means verbose.
       ./sbin/route -p 0 -d -v flush

Note that, if you want to modify the route table, you must use -p to execute the same command for each f-stack process.

For more details, see Manual page.

top

Usage:

top [-p <f-stack proc_id>] [-P <max proc_id>] [-d <secs>] [-n <num>]

Examples:

./sbin/top -p 0 -P 3

how to implement a custom tool for communicating with F-Stack process

Add a new FF_MSG_TYPE in ff_msg.h:

enum FF_MSG_TYPE {
    FF_UNKNOWN = 0,
    FF_SYSCTL,
    FF_HELLOWORLD,
};

Define a structure used to communicate:

struct ff_helloworld_args {
    void *request;
    size_t req_len;
    void *reply;
    size_t rep_len;
};

Note that, when using struct ff_helloworld_args, pointers in this structure must point to the addresses range from ff_msg.buf_addr and ff_msg.buf_addr+ff_msg.buf_len, ff_msg.buf_len is (10240 - sizeof(struct ff_msg)).

And add it to ff_msg:

struct ff_msg {
    ...
    union {
        struct ff_sysctl_args sysctl;
        struct ff_helloworld_args helloworld;
    };
};

Modify ff_dpdk_if.c, add a handle function:

static inline void
handle_helloworld_msg(struct ff_msg *msg, uint16_t proc_id)
{
    printf("helloworld msg recved.\n");
    msg->result = 0;
    rte_ring_enqueue(msg_ring[proc_id].ring[1], msg);
}

static inline void
handle_msg(struct ff_msg *msg, uint16_t proc_id)
{
    switch (msg->msg_type) {
        case FF_SYSCTL:
            handle_sysctl_msg(msg, proc_id);
            break;
        case FF_HELLOWORLD:
            handle_helloworld_msg(msg, proc_id);
        default:
            handle_default_msg(msg, proc_id);
            break;
    }
}

Create helloworld.c:

int main()
{
    struct ff_msg *msg = ff_ipc_msg_alloc();

    char *buf = msg->buf_addr;

    msg->helloworld.request = buf;
    memcpy(msg->helloworld.request, "hello", 5);
    msg->helloworld.req_len = 5;
    buf += 5;

    msg->helloworld.reply = buf;
    msg->helloworld.rep_len = 10;

    ff_ipc_send(msg, 0);

    struct ff_msg *retmsg;
    ff_ipc_recv(retmsg, 0);
    assert(remsg==msg);

    ff_ipc_msg_free(msg);
}

The Makefile may like this:

TOPDIR?=${CURDIR}/../..

PROG=helloworld

include ${TOPDIR}/tools/prog.mk
