* sys/net* : for pointers replace 0 with NULL.pfg2016-04-151-1/+1
| | | | | | Mostly cosmetical, no functional change. Found with devel/coccinelle.
* Split in6_selectsrc() into in6_selectsrc_addr() and in6_selectsrc_socket().melifaro2016-01-101-26/+7
| | | | | | | | | | | | | | | | in6_selectsrc() has 2 class of users: socket-based one (raw/udp/pcb/etc) and socket-less (ND code). The main reason for that change is inability to specify non-default FIB for callers w/o socket since (internally) inpcb is used to determine fib. As as result, add 2 wrappers for in6_selectsrc() (making in6_selectsrc() static): 1) in6_selectsrc_socket() for the former class. Embed scope_ambiguous check along with returning hop limit when needed. 2) in6_selectsrc_addr() for the latter case. Add 'fibnum' argument and pass IPv6 address w/ explicitly specified scope as separate argument. Reviewed by: ae (previous version)
* Remove 'struct route_int6' argument from in6_selectsrc() andmelifaro2016-01-031-2/+2
| | | | | | | | | | | | | | | in6_selectif(). The main task of in6_selectsrc() is to return IPv6 SAS (along with output interface used for scope checks). No data-path code uses route argument for caching. The only users are icmp6 (reflect code), ND6 ns/na generation code. All this fucntions are control-plane, so there is no reason to try to 'optimize' something by passing cached route into to ip6_output(). Given that, simplify code by eliminating in6_selectsrc() 'struct route_in6' argument. Since in6_selectif() is used only by in6_selectsrc(), eliminate its 'struct route_in6' argument, too. While here, reshape rte-related code inside in6_selectif() to free lookup result immediately after saving all the needed fields.

* MFp4: anchie_soc2009 branch:anchie2010-08-191-0/+20
| | | | | | | | | | | | | | | | | | | | Add kernel side support for Secure Neighbor Discovery (SeND), RFC 3971. The implementation consists of a kernel module that gets packets from the nd6 code, sends them to user space on a dedicated socket and reinjects them back for further processing. Hooks are used from nd6 code paths to divert relevant packets to the send implementation for processing in user space. The hooks are only triggered if the send module is loaded. In case no user space application is connected to the send socket, processing continues normaly as if the module would not be loaded. Unloading the module is not possible at this time due to missing nd6 locking. The native SeND socket is similar to a raw IPv6 socket but with its own, internal pseudo-protocol.

Remove the need for some "init" functions within the network stack, like pim6_init(), icmp_init() or significantly shorten others like ip6_init() and nd6_init(), using static initialization again where possible and formerly missed. Move (most) variables back to the place they used to be before the container structs and VIMAGE_GLOABLS (before r185088) and try to reduce the diff to stable/7 and earlier as good as possible, to help out-of-tree consumers to update from 6.x or 7.x to 8 or 9.

If you are running with a vnet (virtual network stack) those will return true and defer you to classic IP-jails handling and thus things will be "denied" or returned with an error. Work around this problem by introducing another "jailed()" function, jailed_without_vnet(), that also takes vnets into account, and permits the calls, should the jail from the given cred have its own virtual network stack. We cannot change the classic jailed() call to do that, as it is used outside the network stack as well. Discussed with: julian, zec, jamie, rwatson (back in Sept) MFC after: 5 days

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | (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.

Turning on options VIMAGE at compile time yields the following changes relative to default kernel build: 1) V_ accessor macros for virtualized variables resolve to structure fields via base pointers, instead of being resolved as fields in global structs or plain global variables. As an example, V_ifnet becomes: options VIMAGE: ((struct vnet_net *) vnet_net)->_ifnet default build: vnet_net_0._ifnet options VIMAGE_GLOBALS: ifnet 2) INIT_VNET_* macros will declare and set up base pointers to be used by V_ accessor macros, instead of resolving to whitespace: INIT_VNET_NET(ifp->if_vnet); becomes struct vnet_net *vnet_net = (ifp->if_vnet)->mod_data[VNET_MOD_NET]; 3) Memory for vnet modules registered via vnet_mod_register() is now allocated at run time in sys/kern/kern_vimage.c, instead of per vnet module structs being declared as globals. If required, vnet modules can now request the framework to provide them with allocated bzeroed memory by filling in the vmi_size field in their vmi_modinfo structures. 4) structs socket, ifnet, inpcbinfo, tcpcb and syncache_head are extended to hold a pointer to the parent vnet. options VIMAGE builds will fill in those fields as required. 5) curvnet is introduced as a new global variable in options VIMAGE builds, always pointing to the default and only struct vnet. 6) struct sysctl_oid has been extended with additional two fields to store major and minor virtualization module identifiers, oid_v_subs and oid_v_mod. SYSCTL_V_* family of macros will fill in those fields accordingly, and store the offset in the appropriate vnet container struct in oid_arg1. In sysctl handlers dealing with virtualized sysctls, the SYSCTL_RESOLVE_V_ARG1() macro will compute the address of the target variable and make it available in arg1 variable for further processing. Unused fields in structs vnet_inet, vnet_inet6 and vnet_ipfw have been deleted. Reviewed by: bz, rwatson Approved by: julian (mentor)

NOTE WELL: * This code hasn't been tested against real MLDv2 queriers (yet), although the on-wire protocol has been verified in Wireshark. * There are a few unresolved issues in the socket layer APIs to do with scope ID propagation. * There is a LOR present in ip6_output()'s use of in6_setscope() which needs to be resolved. See comments in mld6.c. This is believed to be benign and can't be avoided for the moment without re-introducing an indirect netisr.

This enhances the current jail implementation to permit multiple addresses per jail. In addtion to IPv4, IPv6 is supported as well. Due to updated checks it is even possible to have jails without an IP address at all, which basically gives one a chroot with restricted process view, no networking,.. SCTP support was updated and supports IPv6 in jails as well. Cpuset support permits jails to be bound to specific processor sets after creation. Jails can have an unrestricted (no duplicate protection, etc.) name in addition to the hostname. The jail name cannot be changed from within a jail and is considered to be used for management purposes or as audit-token in the future. DDB 'show jails' command was added to aid debugging. Proper compat support permits 32bit jail binaries to be used on 64bit systems to manage jails. Also backward compatibility was preserved where possible: for jail v1 syscalls, as well as with user space management utilities. Both jail as well as prison version were updated for the new features. A gap was intentionally left as the intermediate versions had been used by various patches floating around the last years. Bump __FreeBSD_version for the afore mentioned and in kernel changes.

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/...
