| | | | | | | | | | | | | | | | | | | | | | | | | | | | framework for non-MPSAFE network protocols: - Remove debug_mpsafenet variable, sysctl, and tunable. - Remove NET_NEEDS_GIANT() and associate SYSINITSs used by it to force debug.mpsafenet=0 if non-MPSAFE protocols are compiled into the kernel. - Remove logic to automatically flag interrupt handlers as non-MPSAFE if debug.mpsafenet is set for an INTR_TYPE_NET handler. - Remove logic to automatically flag netisr handlers as non-MPSAFE if debug.mpsafenet is set. - Remove references in a few subsystems, including NFS and Cronyx drivers, which keyed off debug_mpsafenet to determine various aspects of their own locking behavior. - Convert NET_LOCK_GIANT(), NET_UNLOCK_GIANT(), and NET_ASSERT_GIANT into no-op's, as their entire behavior was determined by the value in debug_mpsafenet. - Alias NET_CALLOUT_MPSAFE to CALLOUT_MPSAFE. Many remaining references to NET_.*_GIANT() and NET_CALLOUT_MPSAFE are still present in subsystems, and will be removed in followup commits.

* Various bpf(4) related fixes to catch places up to the new bpf(4)John Baldwin2006-12-291-4/+2
| | | | | | | | | | | | | | | | semantics. - Stop testing bpf pointers for NULL. In some cases use bpf_peers_present() and then call the function directly inside the conditional block instead of the macro. - For places where the entire conditional block is the macro, remove the test and make the macro unconditional. - Use BPF_MTAP() in if_pfsync on FreeBSD instead of an expanded version of the old semantics.

* Restore if_cp.c 1.27Roman Kurakin2005-09-271-2/+3
| | | | | | | | | | | | | | | | | | | ---------------------------- revision 1.27 date: 2005/09/19 03:10:16; author: imp; state: Exp; lines: +3 -2 Make sure that we call if_free(ifp) after bus_teardown_intr. Since we could get an interrupt after we free the ifp, and the interrupt handler depended on the ifp being still alive, this could, in theory, cause a crash. Eliminate this possibility by moving the if_free to after the bus_teardown_intr() call. In fact, this change do nothing for this driver. It is protected from this by cp_destroy variable. This variable also protects driver from initiation of any activity from network stack with disabled intr handler with this change applied. Notes: svn path=/head/; revision=150624

| | | | | | | | | | | | | | | | | 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.

* Stop embedding struct ifnet at the top of driver softcs. Instead theBrooks Davis2005-06-101-65/+73
| | | | | | | | | | | | | | | | | | | | | | | 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.
