There is no\nprotection against entries being added to or removed from a chain while the\nchain is in use. The issues were discussed in this thread:\n\n http://marc.theaimsgroup.com/?l\u003dlinux-kernel\u0026m\u003d113018709002036\u0026w\u003d2\n\nWe noticed that notifier chains in the kernel fall into two basic usage\nclasses:\n\n\t\"Blocking\" chains are always called from a process context\n\tand the callout routines are allowed to sleep;\n\n\t\"Atomic\" chains can be called from an atomic context and\n\tthe callout routines are not allowed to sleep.\n\nWe decided to codify this distinction and make it part of the API. Therefore\nthis set of patches introduces three new, parallel APIs: one for blocking\nnotifiers, one for atomic notifiers, and one for \"raw\" notifiers (which is\nreally just the old API under a new name). New kinds of data structures are\nused for the heads of the chains, and new routines are defined for\nregistration, unregistration, and calling a chain. The three APIs are\nexplained in include/linux/notifier.h and their implementation is in\nkernel/sys.c.\n\nWith atomic and blocking chains, the implementation guarantees that the chain\nlinks will not be corrupted and that chain callers will not get messed up by\nentries being added or removed. For raw chains the implementation provides no\nguarantees at all; users of this API must provide their own protections. (The\nidea was that situations may come up where the assumptions of the atomic and\nblocking APIs are not appropriate, so it should be possible for users to\nhandle these things in their own way.)\n\nThere are some limitations, which should not be too hard to live with. For\natomic/blocking chains, registration and unregistration must always be done in\na process context since the chain is protected by a mutex/rwsem. Also, a\ncallout routine for a non-raw chain must not try to register or unregister\nentries on its own chain. (This did happen in a couple of places and the code\nhad to be changed to avoid it.)\n\nSince atomic chains may be called from within an NMI handler, they cannot use\nspinlocks for synchronization. Instead we use RCU. The overhead falls almost\nentirely in the unregister routine, which is okay since unregistration is much\nless frequent that calling a chain.\n\nHere is the list of chains that we adjusted and their classifications. None\nof them use the raw API, so for the moment it is only a placeholder.\n\n ATOMIC CHAINS\n -------------\narch/i386/kernel/traps.c:\t\ti386die_chain\narch/ia64/kernel/traps.c:\t\tia64die_chain\narch/powerpc/kernel/traps.c:\t\tpowerpc_die_chain\narch/sparc64/kernel/traps.c:\t\tsparc64die_chain\narch/x86_64/kernel/traps.c:\t\tdie_chain\ndrivers/char/ipmi/ipmi_si_intf.c:\txaction_notifier_list\nkernel/panic.c:\t\t\t\tpanic_notifier_list\nkernel/profile.c:\t\t\ttask_free_notifier\nnet/bluetooth/hci_core.c:\t\thci_notifier\nnet/ipv4/netfilter/ip_conntrack_core.c:\tip_conntrack_chain\nnet/ipv4/netfilter/ip_conntrack_core.c:\tip_conntrack_expect_chain\nnet/ipv6/addrconf.c:\t\t\tinet6addr_chain\nnet/netfilter/nf_conntrack_core.c:\tnf_conntrack_chain\nnet/netfilter/nf_conntrack_core.c:\tnf_conntrack_expect_chain\nnet/netlink/af_netlink.c:\t\tnetlink_chain\n\n BLOCKING CHAINS\n ---------------\narch/powerpc/platforms/pseries/reconfig.c:\tpSeries_reconfig_chain\narch/s390/kernel/process.c:\t\tidle_chain\narch/x86_64/kernel/process.c\t\tidle_notifier\ndrivers/base/memory.c:\t\t\tmemory_chain\ndrivers/cpufreq/cpufreq.c\t\tcpufreq_policy_notifier_list\ndrivers/cpufreq/cpufreq.c\t\tcpufreq_transition_notifier_list\ndrivers/macintosh/adb.c:\t\tadb_client_list\ndrivers/macintosh/via-pmu.c\t\tsleep_notifier_list\ndrivers/macintosh/via-pmu68k.c\t\tsleep_notifier_list\ndrivers/macintosh/windfarm_core.c\twf_client_list\ndrivers/usb/core/notify.c\t\tusb_notifier_list\ndrivers/video/fbmem.c\t\t\tfb_notifier_list\nkernel/cpu.c\t\t\t\tcpu_chain\nkernel/module.c\t\t\t\tmodule_notify_list\nkernel/profile.c\t\t\tmunmap_notifier\nkernel/profile.c\t\t\ttask_exit_notifier\nkernel/sys.c\t\t\t\treboot_notifier_list\nnet/core/dev.c\t\t\t\tnetdev_chain\nnet/decnet/dn_dev.c:\t\t\tdnaddr_chain\nnet/ipv4/devinet.c:\t\t\tinetaddr_chain\n\nIt\u0027s possible that some of these classifications are wrong.

This makes\n page table flushing paths properly synchronize with both\n TSB growing and TLB context changes.\n\n3) TSB growing events are moved to the end of successful fault\n processing. Previously it was in update_mmu_cache() but\n that is deadlock prone. At the end of do_sparc64_fault()\n we hold no spinlocks that could deadlock the TSB grow\n sequence. We also have dropped the address space semaphore.\n\nWhile we\u0027re here, add prefetching to the copy_tsb() routine\nand put it in assembler into the tsb.S file. This piece of\ncode is quite time critical.\n\nThere are some small negative side effects to this code which\ncan be improved upon. In particular we grab the mm-\u003econtext.lock\neven for the tsb insert done by update_mmu_cache() now and that\u0027s\na bit excessive. We can get rid of that locking, and the same\nlock taking in flush_tsb_user(), by disabling PSTATE_IE around\nthe whole operation including the capturing of the tsb pointer\nand tsb_nentries value. That would work because anyone growing\nthe TSB won\u0027t free up the old TSB until all cpus respond to the\nTSB change cross call.\n\nI\u0027m not quite so confident in that optimization to put it in\nright now, but eventually we might be able to and the description\nis here for reference.\n\nThis code seems very solid now. It passes several parallel GCC\nbootstrap builds, and our favorite \"nut cruncher\" stress test which is\na full \"make -j8192\" build of a \"make allmodconfig\" kernel. That puts\nabout 256 processes on each cpu\u0027s run queue, makes lots of process cpu\nmigrations occur, causes lots of page table and TLB flushing activity,\nincurs many context version number changes, and it swaps the machine\nreal far out to disk even though there is 16GB of ram on this test\nsystem. :-)\n\nSigned-off-by: David S.

We do our basic\n kernel calls using this stack, which is locked into the kernel\n image, then go to our proper thread stack after taking over the\n trap table.\n\n4) While we are in this delicate startup state, we put 0xdeadbeef\n into %g4/%g5/%g6 in order to catch accidental accesses.\n\n5) On the final prom_set_trap_table*() call, we put \u0026init_thread_union\n into %g6.

What we need to do is:\n\n1) Walk each PCI bus above this device on the path to the\n PCI controller nexus, and for each:\n a) If interrupt-map exists, apply it, record IRQ controller node\n b) Else, swivel interrupt number using PCI_SLOT(), use PCI bus\n\t parent OBP node as controller node\n c) Walk up to \"controller node\" until we hit the first PCI bus\n\t in this domain, or \"controller node\" is the PCI controller\n\t OBP node\n2) If we walked to PCI controller OBP node, we\u0027re done.\n3) Else, apply PCI controller interrupt-map to interrupt.\n\nThere is some stuff that needs to be checked out for ebus and\nisa, but the PCI part is good to go.\n\nSigned-off-by: David S.
