IMA: iint put in ima_counts_get and put
ima_counts_get() calls ima_iint_find_insert_get() which takes a reference
to the iint in question, but does not put that reference at the end of the
function. This can lead to a nasty memory leak. Easy enough to reproduce:
#include <sys/mman.h>
#include <stdio.h>
int main (void)
{
int i;
void *ptr;
for (i=0; i < 100000; i++) {
ptr = mmap(NULL, 4096, PROT_READ|PROT_WRITE,
MAP_SHARED|MAP_ANONYMOUS, -1, 0);
if (ptr == MAP_FAILED)
return 2;
munmap(ptr, 4096);
}
return 0;
}
