There's a task ring for executing commands in a sleep-safe context. This task is used to deliver mbufs (for events, not data), but it's possible that the queue overruns. In that case it does leak mbufs. For now, assert the size to see if we hit the issue. |

Add lock stack trace saving for witness(4). This lets witness(4) save a stack trace on each lock acquisition. The saved traces can be viewed in ddb(4) when showing the currently held locks, which may help when debugging incorrect locking. Sample output: ddb{0}> show all locks Process 63836 (rm) thread 0xffff8000221e52c8 (435004) exclusive rrwlock inode r = 0 (0xfffffd8119a092c0) locked @ /usr/src/sys/ufs/ufs/ufs_vnops.c:1547 #0 witness_lock+0x419 #1 _rw_enter+0x2bb #2 _rrw_enter+0x42 #3 VOP_LOCK+0x3f #4 vn_lock+0x36 #5 vfs_lookup+0xa1 #6 namei+0x2b3 #7 dounlinkat+0x85 #8 syscall+0x338 #9 Xsyscall+0x128 exclusive kernel_lock &kernel_lock r = 1 (0xffffffff81e6a5f0) locked @ /usr/src/sys/arch/amd64/amd64/intr.c:525 #0 witness_lock+0x419 #1 syscall+0x2b6 #2 Xsyscall+0x128 The saving adds overhead, so it is not enabled by default. It can be taken into use by setting sysctl kern.witness.locktrace=1 at runtime or by defining WITNESS_LOCKTRACE in the kernel configuration. Feedback and OK anton@ |

make it possible to reduce kmem pressure by letting some pools use a more accomodating allocator. an interrupt safe pool may also be used in process context, as indicated by waitok flags. thanks to the garbage collector, we can always free pages in process context. the only complication is where to put the pages. solve this by saving the allocation flags in the pool page header so the free function can examine them. not actually used in this diff. (coming soon.) arm testing and compile fixes from phessler |

remove the implict RTF_MPATH flag that rt_ifa_add() sets on new routes. MPLS interfaces (ab)use rt_ifa_add for adding the local MPLS label that they listen on for incoming packets, while every other use of rt_ifa_add is for adding addresses on local interfaces. MPLS does this cos the addresses involved are in basically the same shape as ones used for setting up local addresses. It is appropriate for interfaces to want RTF_MPATH on local addresses, but in the MPLS case it means you can have multiple local things listening on the same label, which doesn't actually work. mpe in particular keeps track of in use labels to it can handle collisions, however, mpw does not. It is currently possible to have multiple mpw interfaces on the same local label, and sharing the same label as mpe or possible normal forwarding labels. Moving the RTF_MPATH flag out of rt_ifa_add means all the callers that still want it need to pass it themselves. The mpe and mpw callers are left alone without the flag, and will now get EEXIST from rt_ifa_add when a label is already in use. ok (and a huge amount of patience and help) mpi@ claudio@ is ok with the idea, but saw a much much earlier solution to the problem |

get rid of the global list of mpe interfaces, it's not needed anymore mpe would try to detect label collisions itself, but wasn't coordinating with mpw or other labels, making it's solution incomplete. this also means i won't need extra locking if i try to make the ioctl paths mpsafe. |

change rt_ifa_add and rt_ifa_del so they take an rdomain argument. this allows mpls interfaces (mpe, mpw) to pass the rdomain they wish the local label to be in, rather than have it implicitly forced to 0 by these functions. right now they'll pass 0, but it will soon be possible to have them rx packets in other rdomains. previously the functions used ifp->if_rdomain for the rdomain. everything other than mpls still passes ifp->if_rdomain. ok mpi@ |

don't confuse the interface rdomain with the one the local label is in. SIOCSIFRDOMAIN is about the routes on top of an mpe interface. the rdomain mpls operates in is independent of that, and currently restricted to rdomain 0. |
