DoS

Denial of Service and kernel panic (out of mbuf) appears when following program executes (originally reported by Sven Berkenvs ([EMAIL PROTECTED])). Affects FreeBSD 3.x & 4.0, OpenBSD 2.5, OpenBSD 2.6, NetBSD 1.4.1. #include #include #include #define BUFFERSIZE 204800 int main () {

vm_fault() problem

It seems to be a problem in vm/vm_fault() and vnode_pager_generic_putpages() in FreeBSD 3.x & 4.0. The following code illustrates the problem: #include #include #include #include #include #define COUNT 1024 #define SIZE10*1024*1024 int main () { int i,j,fd; char *fptr, fnam

Oh, I'm sorry, I made a mistake when posting code. I posted incorrectly patched version... This version correct : #include #include #include #include #include #include #include main(int argc, char *argv[]) { int fd; int i; int len=1024*1024*10; /*ie 10Mbytes*/ caddr_t add

mmap bug

This small program, running as 'mmap', not 'mmap -u', can hang my machine. Is this a known bug in FreeBSD's kernel, or it is my fantasy ? Thank you for answer. #include #include #include #include #include #include #include main(int argc, char *argv[]) { int fd; int i; i
