Hi, I would like to know the memory usage that happens between user space and kernel space communication. Communication happens via generic netlink library and we need to register doit and dump functions. I was going through function "nl80211_set_mesh_params" in "net/wireless/nl80211.c" which receives values of mesh parameters. In this function skb is passed but it is never used and the skb is not freed. I saw other functions also which receives messages from user space but no memory is released for skb. Where is this memory getting free? Do I need to free this memory? When I executed iw commands to set few values in loop. I saw there is drop in free memory of "top" command. I am working on compatwireless-2010-06-27. Thanks, Saurabh Jain "DISCLAIMER: This message is proprietary to Aricent and is intended solely for the use of the individual to whom it is addressed.
