* vlan: Change vlan_dev_set_vlan_flag() to handle multiple flags at oncePatrick McHardy2008-07-06
| | | | | | | | | | Change vlan_dev_set_vlan_flag() to handle multiple flags at once and rename to vlan_dev_change_flags(). This allows to to use it from the netlink interface, which in turn allows to handle necessary adjustments when changing flags centrally.

* net: Add GARP applicant-only participantPatrick McHardy2008-07-06
| | | | | | | | | Add an implementation of the GARP (Generic Attribute Registration Protocol) applicant-only participant. This will be used by the following patch to add GVRP support to the VLAN code. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S. Miller <davem@davemloft.net>

* net: Add STP demux layerPatrick McHardy2008-07-06
| | | | | | | | | Add small STP demux layer for demuxing STP PDUs based on MAC address. This is needed to run both GARP and STP in parallel (or even load the modules) since both use LLC_SAP_BSPAN. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S. Miller <davem@davemloft.net>

* MIB: add struct net to UDP_INC_STATS_BHPavel Emelyanov2008-07-06
| | | | | | | | | | | | Two special cases here - one is rxrpc - I put init_net there explicitly, since we haven't touched this part yet. The second place is in __udp4_lib_rcv - we already have a struct net there, but I have to move its initialization above to make it ready at the "drop" label.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Only a few ISA controllers need the pausing version of the 8390 core while PCMCIA, later ISA and PCI do not. More importantly the ISA delays can break non ISA boxes so we must use a different build of 8390.c for the two sets of controllers.

* | | tun: Interface to query tun/tap features.Rusty Russell2008-07-03
|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The problem with introducing checksum offload and gso to tun is they need to set dev->features to enable GSO and/or checksumming, which is supposed to be done before register_netdevice(), ie. as part of TUNSETIFF. Unfortunately, TUNSETIFF has always just ignored flags it doesn't understand, so there's no good way of detecting whether the kernel supports new IFF_ flags. This patch implements a TUNGETFEATURES ioctl which returns all the valid IFF flags. It could be extended later to include other features. Here's an example program which uses it: #include <linux/if_tun.h> #include <sys/types.h> #include <sys/ioctl.h> #include <sys/stat.h> #include <fcntl.h> #include <err.h> #include <stdio.h> static struct { unsigned int flag; const char *name; } known_flags[] = { { IFF_TUN, "TUN" }, { IFF_TAP, "TAP" }, { IFF_NO_PI, "NO_PI" }, { IFF_ONE_QUEUE, "ONE_QUEUE" }, }; int main() { unsigned int features, i; int netfd = open("/dev/net/tun", O_RDWR); if (netfd < 0) err(1, "Opening /dev/net/tun"); if (ioctl(netfd, TUNGETFEATURES, &features) != 0) { printf("Kernel does not support TUNGETFEATURES, guessing\n"); features = (IFF_TUN|IFF_TAP|IFF_NO_PI|IFF_ONE_QUEUE); } printf("Available features are: "); for (i = 0; i < sizeof(known_flags)/sizeof(known_flags[0]); i++) { if (features & known_flags[i].flag) { features &= ~known_flags[i].flag; printf("%s ", known_flags[i].name); } } if (features) printf("(UNKNOWN %#x)", features); printf("\n"); return 0; } Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> Acked-by: Max Krasnyansky <maxk@qualcomm.com> Signed-off-by: David S.
