But +as the issue referenced below attests, a sum of 'used' +and 'available' might exceed that total memory amount. + +I'm not sure if this is a problem with our calculation +of the 'used' amount, a flaw in the kernel 'available' +algorithms or some other reason I cannot even imagine. + +Anyway, this patch protects against such a contingency +through the following single line addition of new code +. if (pct_used + pct_misc > 100.0 || pct_misc < 0) ... + +The check for less than zero is not actually necessary +as long as the source numbers remain unsigned. However +should they ever become signed, we'll have protection. + +[ Most of the changes in this commit simply separate ] +[ a variable's definition from its associated logic. ] + +Reference(s): +https://gitlab.com/procps-ng/procps/issues/64 + +Signed-off-by: Jim Warner <james.warner@comcast.net> +--- + top/top.c | 19 ++++++++++++------- + 1 files changed, 12 insertions(+), 7 deletions(-) + +diff --git a/top/top.c b/top/top.c +index 385df1d..948805e 100644 +--- a/top/top.c ++++ b/top/top.c +@@ -5249,21 +5249,26 @@ numa_nope: + { "%-.*s~4", "%-.*s~6", "%-.*s~6", Graph_blks } + }; + char used[SMLBUFSIZ], util[SMLBUFSIZ], dual[MEDBUFSIZ]; +- int ix = w->rc.graph_mems - 1; +- float pct_used = (float)kb_main_used * (100.0 / (float)kb_main_total), ++ float pct_used, pct_misc, pct_swap; ++ int ix, num_used, num_misc; ++ ++ pct_used = (float)kb_main_used * (100.0 / (float)kb_main_total); + #ifdef MEMGRAPH_OLD +- pct_misc = (float)(kb_main_buffers + kb_main_cached) * (100.0 / (float)kb_main_total), ++ pct_misc = (float)(kb_main_buffers + kb_main_cached) * (100.0 / (float)kb_main_total); + #else +- pct_misc = (float)(kb_main_total - kb_main_available - kb_main_used) * (100.0 / (float)kb_main_total), ++ pct_misc = (float)(kb_main_total - kb_main_available - kb_main_used) * (100.0 / (float)kb_main_total); + #endif +- pct_swap = kb_swap_total ?
