Saehie ParK e6dbd3d903 Networking: Fix network device name assignment logic for the case of the local loopback device. There is only one local loopback network device and it is unnumbered 2015-08-25 20:03:25 -06:00

Gregory Nutt b493dde4cf TCP networking: In the TCP connection operation, it was trying to setup the network monitor BEFORE the socket was successfully connected. This, of course, has ALWAYS failed because the socket is not yet connected and the TCP state is not yet correct for a connected socket. However, because of other changes net_startmonitor(0 no returns a failure condition that causes worse problems when trying to connect. The fix is to move the logic that starts the network monitor to AFTER the socket has been successfully connected. 2015-05-31 11:35:28 -06:00
Gregory Nutt 33085cb309 Networking: The network device list was protected by a re-entrant semaphore. With the recent change to support network device callback, the network stack needs to access the network device list too. Some drivers, however, run the network stack from the interrupt level -- this is bad but a fact in the current state. Of course,those drivers are unable to take the semaphore and will assert.
The solution here is to eliminate the device devices semaphore altogether.  This eliminates netdev_semtake() and netdev_semgive() and replaces them with net_lock() and net_unlock() which have larger scope as needed for this purpose.

Gregory Nutt 6687e156e6 Revamp last change. IFF_UP only required when allocating callback, not freeing. 2015-05-30 21:13:58 -06:00
Gregory Nutt 28b46c7bfa To be valid, a network device must not only exist, but be in the UP state 2015-05-30 12:54:18 -06:00

Gregory Nutt ab50e9d04d Networking: Get rid of g_ipv4_allzeroaddr and g_ipv4_alloneaddr. It is more efficient and more intuitive to use INADDR_ANY and INADDR_BROADCAST 2015-05-29 15:16:11 -06:00
Gregory Nutt fa8b7c19b7 Forgot to add a file in the last commit 2015-05-29 11:03:02 -06:00
Gregory Nutt f10fdf7ad4 Networking: Add a test to see a device pointer is still valid 2015-05-29 11:01:03 -06:00
Gregory Nutt 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

Gregory Nutt 5c13722416 Networking: Improve the network device registration logic. When multiple link types are used, modify how each interface number is assigned to the device name by incrementing the device number individually for each interface link type. From Max Neklyudov. 2015-02-27 08:23:14 -06:00
Gregory Nutt 19f3d46eb0 Fix a list handling error in netdev_unregister(). From Max Neklyudov 2015-02-27 08:01:31 -06:00
Gregory Nutt b756df982d net/: Lots of build problems introduced into multiple NIC support. Many places where conditional logic based on CONFIG_NETDEV_MULTINIC is confused with CONFIG_NET_MULTILINK. Lots of code changed with IPv6 that was never compiled with MULTINIC enabled. Still some problem with parameter passing. 2015-02-09 18:15:34 -06:00

Gregory Nutt eb3c6e8390 Networking: Some fixes for compilation when both IPv4 and IPv6 are enabled 2015-01-18 09:23:22 -06:00
Gregory Nutt 2663538b0a Networking: Replace all references to the macros net_ipaddr_copy, net_ipaddr_hdrcopy, net_ipaddr_cmp, net_ipaddr_hdrcmp, and net_ipaddr_maskcmp with the appropriate IPv4 or IPv6 version of the macro (such as net_ipv4addr_copy). The goal is to support both IPv4 and IPv6 simultaneously. This requires that the macros be distinct and not conditionally defined to one on or the other. 2015-01-16 13:01:08 -06:00
Gregory Nutt 5e938941a6 Networking: Replace all references to net_ipaddr_t with either in_addr_t on net_ipv6addr_t. The goal is to support both IPv4 and IPv6 simultaneously. This requires that the two types be distinct and not conditionally typedef'ed to net_ipaddr_t. 2015-01-16 12:30:18 -06:00
Gregory Nutt bee89be4f4 Networking: Drivers can have both IPv4 and IPv6 addesses, but a socket can only only one or the other; The socket connnection structures need to include a union of IPv4 and IPv6 addresses for the local address binding and for the remote address connections 2015-01-16 10:01:54 -06:00
Gregory Nutt fe8b3c5220 Networking: More detangling of IPv6 logic. Next steps will be more invasive and will get moved to a branch 2015-01-16 08:51:18 -06:00

Gregory Nutt b36dbe1d89 Add logic to netdev_findbyaddr() to return the correct network device for the case where a broadcast address is used. This change caused trivial ripples through other files because additional parameters are required for netdev_findbyaddr() when CONFIG_NET_MULTINIC 2014-11-23 11:00:22 -06:00
