2008-05-22tipc: Fix skb_under_panic when configuring TIPC without privilegesAllan Stephens1-7/+9
This patch prevents a TIPC configuration command requiring network administrator privileges from triggering an skbuff underrun if it is issued by a process lacking those privileges. The revised error handling code avoids the use of a potentially uninitialized global variable by transforming the unauthorized command into a new command, then following the standard command processing path to generate the required error message.

2007-06-24[TIPC]: Fix infinite loop in netlink handlerFlorian Westphal1-1/+1
The tipc netlink config handler uses the nlmsg_pid from the request header as destination for its reply. If the application initialized nlmsg_pid to 0, the reply is looped back to the kernel, causing hangup. Fix: use nlmsg_pid of the skb that triggered the request.

2006-01-14[PATCH] genetlink: don't touch module ref countPer Liden1-1/+0
Increasing the module ref count at registration will block the module from ever being unloaded. In fact, genetlink should not care about the owner at all. This patch removes the owner field from the struct registered with genetlink.
