vlib: set log tap level <level> does not work for some keywords
While some levels such as debug and emerg work, others don't. See below. DBGvpp# set log class tap level warn set log class tap level warn set logging class: unknown input `level warn' DBGvpp# set log class tap level debug set log class tap level debug DBGvpp# set log class tap level info set log class tap level info set logging class: unknown input `level info' DBGvpp# set log class tap level err set log class tap level err DBGvpp# set log class tap level crit set log class tap level crit set logging class: unknown input `level crit' DBGvpp# set log class tap level emerg set log class tap level emerg DBGvpp# Cause: The reason for the failure for the shorter keywords is level_str is unformatted with %v which is not null terminated. For example, the character after "info" could be anything in level_str. The memcmp with size of the macro keyword __##uc which includes the null character or 5 in this case and thus the comparison fails. Fix: Use %s which insure level_str is null terminated. Use strcmp to rule out false positve match like "debugxxx" against keyword "debug". Change-Id: I7a2d97a0f7f618df105da7eca791618dce04d21e Signed-off-by: Steven <sluong@cisco.com>
