In xmit, there is a skb_clone. This function copies the struct sk_buff. And some parameters are changed to the new skb. Then the new skb is sent while the old skb is freed. While the function skb_clone is removed, the parameter changes are made on the old skb, then the old skb is sent. It can also work well. The following tests are made. server client --------- --------- |1.1.1.1|<----rxe-channel--->|1.1.1.2| --------- --------- On server: rping -s -a 1.1.1.1 -v -C 1000 -S 512 On client: rping -c -a 1.1.1.1 -v -C 1000 -S 512 The kernel config CONFIG_DEBUG_KMEMLEAK is enabled on both server and client. This test runs for several hours. There is no memory leak and the whole system can work well. As the above network, the following tests are made. Server: ibv_rc_pingpong -d rxe0 -g 1 Client: ibv_rc_pingpong -d rxe0 -g 1 1.1.1.1 The result on Server. Before: 8192000 bytes in 0.88 seconds = 74.36 Mbit/sec 1000 iters in 0.88 seconds = 881.30 usec/iter After: 8192000 bytes in 0.81 seconds = 81.15 Mbit/sec 1000 iters in 0.81 seconds = 807.62 usec/iter The throughput is enhanced and the latency is reduced.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
