| H A D | kern_jail.c | diff 81114 Fri Aug 03 16:21:06 MDT 2001 rwatson Anton kindly pointed out (and fixed) a bug in the Jail handling of the bind() call on IPv4 sockets: Currently, if one tries to bind a socket using INADDR_LOOPBACK inside a jail, it will fail because prison_ip() does not take this possibility into account. On the other hand, when one tries to connect(), for example, to localhost, prison_remote_ip() will silently convert INADDR_LOOPBACK to the jail's IP address. Therefore, it is desirable to make bind() to do this implicit conversion as well. Apart from this, the patch also replaces 0x7f000001 in prison_remote_ip() to a more correct INADDR_LOOPBACK. This is a 4.4-RELEASE "during the freeze, thanks" MFC candidate. Submitted by: Anton Berezin <tobez@FreeBSD.org> Discussed with at some point: phk MFC after: 3 days |
