callback: mark cb_ctl_array 'const' in mnl_cb_run2()
Users of mnl_cb_run2() would typically pass a 'static const' array as cb_ctl_array parameter. Unfortunately this triggers a compiler warning because the prototype doesn't declare cb_ctl_array with the 'const' qualifier. Since mnl_cb_run2() and __mnl_cb_run() don't modify cb_ctl_array (and don't have any reason to do so in the future), we can mark this parameter as 'const'. There should be no impact on existing users beyond removing the compiler warning when using a constant array. Signed-off-by: Guillaume Nault <> Signed-off-by: Pablo Neira Ayuso <>
