_user_get_system_info()] needs to be changed to copy no more than
requested back to userland, though.
I don't understand this. Within this function the size parameter is only
used in the following line:
{{{
status_t status = _get_system_info(&info, size);
}}}
and this call returns B_BAD_VALUE anyway when size != sizeof(system_info).
It seems to me that the size parameter is pretty useless.
I am attaching a patch that I think should be sufficient. I don't dare to
make the commit myself in fear of the wrath of the Haiku kernel developers
:D
After this patch is accepted I will work on the AboutSystem app to report
inaccessible memory. sysinfo will revert to its old behavior, which is
probably better.
