NETLINK_ADD_MEMBERSHIP/NETLINK_DROP_MEMBERSHIP are used to join/leave groups, NETLINK_PKTINFO is used to enable nl_pktinfo control messages for received packets to get the extended destination group number. Signed-off-by:

This is necessary for dynamic number of netlink groups to make sure we know the number of possible groups before bind() is called. With this change pure userspace communication using unused netlink protocols becomes impossible. Signed-off-by:

Using the group number allows increasing the number of groups without beeing limited by the size of the bitmask. It introduces one limitation for netlink users: messages can't be broadcasted to multiple groups anymore, however this feature was never used inside the kernel. Signed-off-by:

Use-after-free: the struct proto_ops containing the module pointer is freed when a socket with pid=0 is released, which besides for kernel sockets is true for all unbound sockets. Module refcount leak: when the kernel socket is closed before all user sockets have been closed the proto_ops struct for this family is replaced by the generic one and the module refcount can't be dropped. The second problem can't be solved cleanly using module refcounting in the generic socket code, so this patch adds explicit refcounting to netlink_create/netlink_release. Signed-off-by:

w1 does not need to multicast its state to several groups at once, and upcoming netlink changes will not allow bitmask for groups anyway. Signed-off-by:

As proposed by Andi Kleen, this is required esp. for x86_64 architecture, where 64bit code needs 8byte aligned 64bit data types, but 32bit userspace apps will only align to 4bytes. Signed-off-by:

With this the previous setup is back, i.e. tcp_diag can be built as a module, as dccp_diag and both share the infrastructure available in inet_diag. If one selects CONFIG_INET_DIAG as module CONFIG_INET_TCP_DIAG will also be built as a module, as will CONFIG_INET_DCCP_DIAG, if CONFIG_IP_DCCP was selected static or as a module, if CONFIG_INET_DIAG is y, being statically linked CONFIG_INET_TCP_DIAG will follow suit and CONFIG_INET_DCCP_DIAG will be built in the same manner as CONFIG_IP_DCCP. Now to aim at UDP, converting it to use inet_hashinfo, so that we can use iproute2 for UDP sockets as well. Ah, just to show an example of this new infrastructure working for DCCP :-) [root@qemu ~]# ./ss -dane State Recv-Q Send-Q Local Address:Port Peer Address:Port LISTEN 0 0 *:5001 *:* ino:942 sk:cfd503a0 ESTAB 0 0 127.0.0.1:5001 127.0.0.1:32770 ino:943 sk:cfd50a60 ESTAB 0 0 127.0.0.1:32770 127.0.0.1:5001 ino:947 sk:cfd50700 TIME-WAIT 0 0 127.0.0.1:32769 127.0.0.1:5001 timer:(timewait,3.430ms,0) ino:0 sk:cf209620 Signed-off-by:

Next changeset will rename tcp_diag to inet_diag and move the tcp_diag code out of it and into a new tcp_diag.c, similar to the net/dccp/diag.c introduced in this changeset, completing the transition to a generic inet_diag infrastructure. Signed-off-by:

Doing this we allow tcp_diag to support IPV6 even if tcp_diag is compiled statically and IPV6 is compiled as a module, removing the previous restriction while not building any IPV6 code if it is not selected. Now to work on the tcpdiag_register infrastructure and then to rename the whole thing to inetdiag, reflecting its by then completely generic nature. Signed-off-by:

This patch contains the following possible cleanups/fixes: - use C99 struct initializers - make a few arrays and structs static - remove a few uses of literal 0 as NULL pointer - use convenience function instead of cast+dereference in bnx2_ioctl() - remove superfluous casts to u8 * in calls to readl/writel Signed-off-by:
