SVN rev 195699 on 2009-07-14 22:48:30Z by rwatson Build on Jeff Roberson's linker-set based dynamic per-CPU allocator (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.

SVN rev 189106 on 2009-02-27 14:12:05Z by bz For all files including net/vnet.h directly include opt_route.h and 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.

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(*).

Add two new flags to if_bridge(4) indicating whether the edge flag of the bridge port and path cost have been administratively set or calculated automatically by RSTP. Make sure to transition from non-edge to edge when the port goes down and the edge flag was manually set before. This is needed to comply with the condition ((!portEnabled && AdminEdge) || ....) in the Bridge Detection State Machine (IEE802.1D-2004, p. 171). Reviewed by: thompsa Approved by: bz (mentor)

MFp4 - Each stp port is added sequentially so it was possible for our bridgeid to change every time because the new port has a lower MAC address. Instead just find the lowest MAC address from all Ethernet adapters in the machine as the value only needs to be unique, this stops a lot of churn on the protocol. - Update the states after enabling or disabling a port. - Keep tabs if we have been stopped or started by our parent bridge. - The callout only needs to be drained before destroying the mutex, move it to bstp_detach.

RSTP provides faster spanning tree convergence, the protocol will exchange information with neighboring switches to quickly transition to forwarding without creating loops. The code will default to RSTP mode but will downgrade any port connected to a legacy STP network so is fully backward compatible. Reviewed by: syrinx Tested by: syrinx

Forced commit due to missing log on the last revision. Split the spanning tree state into its own structures and provide a simple API to perform functions such as adding and deleting ports. This is just a mechanical change and the STP operation remains the same. The bridgestp code now has no knowledge of if_bridge. This makes the code easier to read and can now also support other bridges such as ng_bridge.

Ensure that we are holding the lock when initialising the bridge interface. We could initialise while unlocked if the bridge is not up when setting the inet address, ether_ioctl() would call bridge_init. Change it so bridge_init is always called unlocked and then locks before calling bstp_initialization(). Reported by: Michal Mertl Approved by: mlaier (mentor) MFC after: 3 days

Propagate rename of IFF_OACTIVE and IFF_RUNNING to IFF_DRV_OACTIVE and IFF_DRV_RUNNING, as well as the move from ifnet.if_flags to ifnet.if_drv_flags. Device drivers are now responsible for synchronizing access to these flags, as they are in if_drv_flags. This helps prevent races between the network stack and device driver in maintaining the interface flags field. Many __FreeBSD__ and __FreeBSD_version checks maintained and continued; some less so.

- Previously when broadcasting to N number of interfaces we would run pfil hooks for each outgoing interface but also run pfil hooks _N times_ on the bridge interface. This is changed so pfil hooks are run once for the bridge interface (bridge0) and then only on the outgoing interfaces in the broadcast loop. - Simplify bridge_enqueue() by moving bridge_pfil() to the callers. - Check (inet6_pfil_hook.ph_busy_count >= 0), it may be possible to have a packet filter hooked for only ipv6 but we were only checking if ipv4 hooks were busy. - Minor optimisation for null mbuf check after bridge_pfil(), move it into the if-block as it couldnt possibly be null outside.

Stop embedding struct ifnet at the top of driver softcs. Instead the 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.
