* Remove IFF_NEEDSGIANT, a compatibility infrastructure introducedrwatson2009-03-151-2/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | in FreeBSD 5.x to allow network device drivers to run with Giant despite the network stack being Giant-free. This significantly simplifies calls into ioctl() on network interfaces, especially in the multicast code, as well as eliminates deferred invocation of interface if_start routines. Disable the build on device drivers still depending on IFF_NEEDSGIANT as they no longer compile. They will be removed in a few weeks if they haven't been made MPSAFE in that time. Disabled drivers: if_ar if_axe if_aue if_cdce if_cue if_kue if_ray if_rue if_rum if_sr if_udav if_ural if_zyd Drivers that were already disabled because of tty changes: if_ppp if_sl Discussed on: arch@
* Rather than using hidden includes (with cicular dependencies),bz2008-12-021-0/+1
| | | | | | | | | | | directly include only the header files needed. This reduces the unneeded spamming of various headers into lots of files. For now, this leaves us with very few modules including vnet.h and thus needing to depend on opt_route.h. Reviewed by: brooks, gnn, des, zec, imp Sponsored by: The FreeBSD Foundation
* Change the initialization methodology for global variables scheduledzec2008-11-191-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | for virtualization. Instead of initializing the affected global variables at instatiation, assign initial values to them in initializer functions. As a rule, initialization at instatiation for such variables should never be introduced again from now on. Furthermore, enclose all instantiations of such global variables in #ifdef VIMAGE_GLOBALS blocks. Essentialy, this change should have zero functional impact. In the next phase of merging network stack virtualization infrastructure from p4/vimage branch, the new initialization methology will allow us to switch between using global variables and their counterparts residing in virtualization containers with minimum code churn, and in the long run allow us to intialize multiple instances of such container structures.

* Step 1.5 of importing the network stack virtualization infrastructurezec2008-10-021-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | from the vimage project, as per plan established at devsummit 08/08: http://wiki.freebsd.org/Image/Notes200808DevSummit Introduce INIT_VNET_*() initializer macros, VNET_FOREACH() iterator macros, and CURVNET_SET() context setting macros, all currently resolving to NOPs. Prepare for virtualization of selected SYSCTL objects by introducing a family of SYSCTL_V_*() macros, currently resolving to their global counterparts, i.e. SYSCTL_V_INT() == SYSCTL_INT(). Move selected #defines from sys/sys/vimage.h to newly introduced header files specific to virtualized subsystems (sys/net/vnet.h, sys/netinet/vinet.h etc.). All the changes are verified to have zero functional impact at this point in time by doing MD5 comparision between pre- and post-change object files(*).

| | | | | | | | | | | | | | | | | | | | | | | | virtualization work done by Marko Zec (zec@). This is the first in a series of commits over the course of the next few weeks. Mark all uses of global variables to be virtualized with a V_ prefix. Use macros to map them back to their global names for now, so this is a NOP change only. We hope to have caught at least 85-90% of what is needed so we do not invalidate a lot of outstanding patches again. Obtained from: //depot/projects/vimage-commit2/...

* Implement reference counting for ifmultiaddr, in_multi, and in6_multibms2007-03-201-72/+83
| | | | | | | | | | | | | | | | | | | structures. Detect when ifnet instances are detached from the network stack and perform appropriate cleanup to prevent memory leaks. This has been implemented in such a way as to be backwards ABI compatible. Kernel consumers are changed to use if_delmulti_ifma(); in_delmulti() is unable to detect interface removal by design, as it performs searches on structures which are removed with the interface. With this architectural change, the panics FreeBSD users have experienced with carp and pfsync should be resolved.

* scope cleanup. with this changeume2005-07-251-41/+52
| | | | | | | | | | | | | | | | | | | - most of the kernel code will not care about the actual encoding of scope zone IDs and won't touch "s6_addr16[1]" directly. - similarly, most of the kernel code will not care about link-local scoped addresses as a special case. - scope boundary check will be stricter. For example, the current *BSD code allows a packet with src=::1 and dst=(some global IPv6 address) to be sent outside of the node, if the application do: s = socket(AF_INET6); bind(s, "::1"); sendto(s, some_global_IPv6_addr); This is clearly wrong, since ::1 is only meaningful within a single node, but the current implementation of the *BSD kernel cannot reject this attempt.
