xc_map_foreign_bulk() memory leak in ARM version?
Hi Xen folks!
I''ve faced with one strange thing in ARM version of Xen: when I use
xc_map_foreign_bulk() to map some memory from domU to dom0, after unmap()
for previous returned address - memory is not freed at all.
Let''s look at call stack:
xc_map_foreign() ->
linux_privcmd_map_foreign_bulk() ->
{
addr = mmap(fd);
ioctl(fd, IOCTL_PRIVCMD_MMAPBATCH_V2 );
