    [NET]: Make /proc/net per network namespace · 457c4cbc
    Eric W. Biederman 提交于
    This patch makes /proc/net per network namespace.  It modifies the global
    variables proc_net and proc_net_stat to be per network namespace.
    The proc_net file helpers are modified to take a network namespace argument,
    and all of their callers are fixed to pass &init_net for that argument.
    This ensures that all of the /proc/net files are only visible and
    usable in the initial network namespace until the code behind them
    has been updated to be handle multiple network namespaces.
    
    Making /proc/net per namespace is necessary as at least some files
    in /proc/net depend upon the set of network devices which is per
    network namespace, and even more files in /proc/net have contents
    that are relevant to a single network namespace.
