Bug#695182: linux-image-3.2.0-4-686-pae: Write couple of 1GB files for OOM crash
Dear Ben,
In response to your comments: x seems to be in the range [-1,1]. The
returned pos_ratio would be within [0,2] if not for the final *8.
---
[Funny: taking difference of unsigned ints and expect the result to be
negative in some sense. Seems the problem was not with large memory but
with negative numbers. Curious the bug was not noticed before.]
Need to cast and sign-extend before taking difference of unsigned
numbers, as the following demonstrates:
$ cat silly.c
#include <stdio.h>
main()
{
unsigned long i,j;
long long x;
i=1; j=2;
x = j-i; printf("j-i = %lld\n",x);
x = i-j; printf("i-j = %lld\n",x);
x = (long long)i-j; printf("OK = %lld\n",x);
}
$ cc silly.c; a.out
j-i = 1
i-j = 4294967295
OK = -1
$
and in fact things go bad, e.g. freerun=2172 limit=2896 dirty=2589
should get x=-155, whereas original formula gets x=11831710 and Ben's
formula gets x=-769071435.
Seems a correct patch would be:
--- old/mm/page-writeback.c 2012-10-17 13:50:15.000000000 +1100
+++ new/mm/page-writeback.c 2012-12-17 12:25:14.000000000 +1100
@@ -559,7 +559,7 @@
* => fast response on large errors; small oscillation near setpoint
*/
setpoint = (freerun + limit) / 2;
- x = div_s64((setpoint - dirty) << RATELIMIT_CALC_SHIFT,
+ x = div_s64(((s64)setpoint - (s64)dirty) << RATELIMIT_CALC_SHIFT,
limit - setpoint + 1);
pos_ratio = x;
pos_ratio = pos_ratio * x >> RATELIMIT_CALC_SHIFT;
However, with that patch in place I still got an OOM crash (log below).
More bugs remain...
Cheers, Paul
