Who understands this stuff? I sent (not quite right) patches for it to Marcel a year ago. Just add (not quite right) COMPAT_43 || COMPAT_SUNOS ifdefs in about 50 places, and avoid calling osigreturn when it doesn't exist. The "not quite right" part is that this has nothing to do with 4.3BSD or SunOS compatibility. It is for 4.4BSD/FreeBSD[2-3] compatibility. Precise ifdefs for it could get very messy. > It is interesting to see that there is NO way to disable all networking > (e.g unix domain sockets) This worked before the accf changes. I asked Alfred to fix them. I only fixed the sysctl problem with it here and am left with the following errors for my minimal kernel: uipc_socket.o: In function `sodealloc': uipc_socket.o(.text+0x262): undefined reference to `M_ACCF' uipc_socket.o(.text+0x272): undefined reference to `M_ACCF' uipc_socket.o: In function `do_setopt_accept_filter': uipc_socket.o(.text+0x1d3e): undefined reference to `M_ACCF' uipc_socket.o(.text+0x1d4e): undefined reference to `M_ACCF' uipc_socket.o(.text+0x1dcd): undefined reference to `accept_filt_get' uipc_socket.o(.text+0x1deb): undefined reference to `M_ACCF' uipc_socket.o(.text+0x1e2a): undefined reference to `M_ACCF' uipc_socket.o(.text+0x1e61): undefined reference to `M_ACCF' uipc_socket.o(.text+0x1e6e): undefined reference to `M_ACCF' Bruce To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
