37381a9e7d net/pkt: add SOCK_DGRAM support 
According to the definitions of PF_PACKET and SOCK_DGRAM,
extend the current protocol stack pkt protocol to support SOCK_DGRAM mode.

Some third-party network libraries use AF_PACKET, SOCK_DGRAM type sockets
to construct packets and send/receive data, This patch can add support
for this.

6fd74f817d net/pkt: Support filtering protocol in AF_PACKET 
Ref: https://man7.org/linux/man-pages/man7/packet.7.html

1. For `socket(AF_PACKET, int socket_type, int protocol)`: When `protocol` is set to `htons(ETH_P_ALL)`, then all protocols are received. If `protocol` is set to zero, no packets are received.
2. For `bind`: `bind` can optionally be called with a nonzero `sll_protocol` to start receiving packets for the protocols specified.

9a23ebdbc0 net/pkt: Support binding to devices other than ETH 
We're using the `sll_ifindex` inside `struct sockaddr_ll` to bind
device, so we don't need to translate it into mac address, we can just
match the index, which also let us bind to different type of devices
other than Ethernet.

Ref: Linux also uses `ifindex` to find related device and note it down without mac addresses.

36fbedcbfc net/devif/devif_callback.c: corrected the connection event list to work as FIFO instead of LIFO. 
In case of enabled packet forwarding mode, packets were forwarded in a reverse order
because of LIFO behavior of the connection event list.
The issue exposed only during high network traffic. Thus the event list started to grow
that resulted in changing the order of packets inside of groups of several packets
like the following: 3, 2, 1, 6, 5, 4, 8, 7 etc.

Remarks concerning the connection event list implementation:
* Now the queue (list) is FIFO as it should be.
* The list is singly linked.
* The list has a head pointer (inside of outer net_driver_s structure),
  and a tail pointer is added into outer net_driver_s structure.
* The list item is devif_callback_s structure.
  It still has two pointers to two different list chains (*nxtconn and *nxtdev).
* As before the first argument (*dev) of the list functions can be NULL,
  while the other argument (*list) is effective (not NULL).
* An extra (*tail) argument is added to devif_callback_alloc()
  and devif_conn_callback_free() functions.
* devif_callback_alloc() time complexity is O(1) (i.e. O(n) to fill the whole list).
* devif_callback_free() time complexity is O(n) (i.e. O(n^2) to empty the whole list).
* devif_conn_event() time complexity is O(n).

1b9cb70828 Sockets: Initial steps to adde a socket interface to the networking. Each address family will have an interface that describes how to perform socket operations on that address family. Currently only a couple of methods are defined in the table as a proof of concept. More to come. Currently there are only tables for the INET/INET6 family, the Unix LOCAL family, and the raw PACKET family. Hopefully there will be AF_IEEE802154 and AF_BLUETOOTH comming down the pike. 2017-07-12 15:07:32 -06:00

e81f279315 Networking: Modify event list handling: Now there are two event lists each device structure: (1) One is for ARP and ICMP data related evetns, the other is for device related events. Callback allocation/free routines no accept a device paramter as well as a list: If the device paramter is added, then the callback goes into both the connection-related liast AND the device event list. Thus each socket type can received both custom data-related events as well as common device related events. 2015-05-28 12:01:38 -06:00
