[PATCH v5 1/5] pdump: fix default socket path
From: Reshma Pattan <hidden>
Date: 2016-06-24 16:36:26
Subsystem:
library code, the rest · Maintainers:
Andrew Morton, Linus Torvalds
SOCKET_PATH_HOME is to specify environment variable "HOME",
so it should not contain "/pdump_sockets" in the macro.
So removed "/pdump_sockets" from SOCKET_PATH_HOME and
SOCKET_PATH_VAR_RUN. New changes will create pdump sockets under
/var/run/.dpdk/pdump_sockets for root users and
under HOME/.dpdk/pdump_sockets for non root users.
Changes are done in pdump_get_socket_path() to accommodate
new socket path changes.
Fixes: 278f945402c5 ("pdump: add new library for packet capture")
