[ Upstream commit 1b97013bfb11d66f041de691de6f0fec748ce016 ] Fix more memory leaks in ip_cmsg_send() callers. Part of them were fixed earlier in 919483096bfe. * udp_sendmsg one was there since the beginning when linux sources were first added to git; * ping_v4_sendmsg one was copy/pasted in c319b4d76b9e. Whenever return happens in udp_sendmsg() or ping_v4_sendmsg() IP options have to be freed if they were allocated previously. Add label so that future callers (if any) can use it instead of kfree() before return that is easy to forget. Fixes: c319b4d76b9e (net: ipv4: add IPPROTO_ICMP socket kind) Signed-off-by: Andrey Ignatov <rdna@fb.com> Signed-off-by: David S.

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.
