* Rework global locks for interface list and index management, correctingrwatson2009-08-231-2/+2
| | | | | | | | | | | | | | several critical bugs, including race conditions and lock order issues: Replace the single rwlock, ifnet_lock, with two locks, an rwlock and an sxlock. Either can be held to stablize the lists and indexes, but both are required to write. This allows the list to be held stable in both network interrupt contexts and sleepable user threads across sleeping memory allocations or device driver interactions. As before, writes to the interface list must occur from sleepable contexts. Reviewed by: bz, julian MFC after: 3 days

* Reimplement and/or implement vnet list locking by replacing a mostlyrwatson2009-07-191-2/+2
| | | | | | | | | | | | | | | | | | | | | | unused custom mutex/condvar-based sleep locks with two locks: an rwlock (for non-sleeping use) and sxlock (for sleeping use). Either acquired for read is sufficient to stabilize the vnet list, but both must be acquired for write to modify the list. Replace previous no-op read locking macros, used in various places in the stack, with actual locking to prevent race conditions. Callers must declare when they may perform unbounded sleeps or not when selecting how to lock. Refactor vnet sysinits so that the vnet list and locks are initialized before kernel modules are linked, as the kernel linker will use them for modules loaded by the boot loader. Update various consumers of these KPIs based on whether they may sleep or not. Reviewed by: bz Approved by: re (kib)
* Build on Jeff Roberson's linker-set based dynamic per-CPU allocatorrwatson2009-07-141-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | (DPCPU), as suggested by Peter Wemm, and implement a new per-virtual network stack memory allocator. Modify vnet to use the allocator instead of monolithic global container structures (vinet, ...). This change solves many binary compatibility problems associated with VIMAGE, and restores ELF symbols for virtualized global variables. Each virtualized global variable exists as a "reference copy", and also once per virtual network stack. Virtualized global variables are tagged at compile-time, placing the in a special linker set, which is loaded into a contiguous region of kernel memory. Virtualized global variables in the base kernel are linked as normal, but those in modules are copied and relocated to a reserved portion of the kernel's vnet region with the help of a the kernel linker. Virtualized global variables exist in per-vnet memory set up when the network stack instance is created, and are initialized statically from the reference copy. Run-time access occurs via an accessor macro, which converts from the current vnet and requested symbol to a per-vnet address. When "options VIMAGE" is not compiled into the kernel, normal global ELF symbols will be used instead and indirection is avoided. This change restores static initialization for network stack global variables, restores support for non-global symbols and types, eliminates the need for many subsystem constructors, eliminates large per-subsystem structures that caused many binary compatibility issues both for monitoring applications (netstat) and kernel modules, removes the per-function INIT_VNET_*() macros throughout the stack, eliminates the need for vnet_symmap ksym(2) munging, and eliminates duplicate definitions of virtualized globals under VIMAGE_GLOBALS.

| | | | | | | | | | | | | | net/route.h. Remove the hidden include of opt_route.h and net/route.h from net/vnet.h. We need to make sure that both opt_route.h and net/route.h are included before net/vnet.h because of the way MRT figures out the number of FIBs from the kernel option. If we do not, we end up with the default number of 1 when including net/vnet.h and array sizes are wrong. This does not change the list of files which depend on opt_route.h but we can identify them now more easily.
* 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

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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/...

* Stop embedding struct ifnet at the top of driver softcs. Instead thebrooks2005-06-101-2/+2
| | | | | | | | | | | | | | | | | | | | struct ifnet or the layer 2 common structure it was embedded in have been replaced with a struct ifnet pointer to be filled by a call to the new function, if_alloc(). The layer 2 common structure is also allocated via if_alloc() based on the interface type. It is hung off the new struct ifnet member, if_l2com. This change removes the size of these structures from the kernel ABI and will allow us to better manage them as interfaces come and go. Other changes of note: - Struct arpcom is no longer referenced in normal interface code. Instead the Ethernet address is accessed via the IFP2ENADDR() macro. To enforce this ac_enaddr has been renamed to _ac_enaddr. - The second argument to ether_ifattach is now always the mac address from driver private storage rather than sometimes being ac_enaddr.
