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.

The code can patch both SMP-\u003eUP and UP-\u003eSMP.\nThe UP-\u003eSMP case is useful for CPU hotplug.\n\nWith CONFIG_CPU_HOTPLUG enabled the code switches to UP at boot time and\nwhen the number of CPUs goes down to 1, and switches to SMP when the number\nof CPUs goes up to 2.\n\nWithout CONFIG_CPU_HOTPLUG or on non-SMP-capable systems the code is\npatched once at boot time (if needed) and the tables are released\nafterwards.\n\nThe changes in detail:\n\n * The current alternatives bits are moved to a separate file,\n the SMP alternatives code is added there.\n\n * The patch adds some new elf sections to the kernel:\n .smp_altinstructions\n\tlike .altinstructions, also contains a list\n\tof alt_instr structs.\n .smp_altinstr_replacement\n\tlike .altinstr_replacement, but also has some space to\n\tsave original instruction before replaving it.\n .smp_locks\n\tlist of pointers to lock prefixes which can be nop\u0027ed\n\tout on UP.\n The first two are used to replace more complex instruction\n sequences such as spinlocks and semaphores.

Interrupt enabling and disabling no\nlonger map to sigprocmask. Rather, a flag is set indicating whether\ninterrupts may be handled. If a signal comes in and interrupts are marked as\nOK, then it is handled normally. If interrupts are marked as off, then the\nsignal handler simply returns after noting that a signal needs handling. When\ninterrupts are enabled later on, this pending signals flag is checked, and the\nIRQ handlers are called at that point.\n\nThe point of this is to reduce the cost of local_irq_save et al, since they\nare very much more common than the signals that they are enabling and\ndisabling. Soft interrupts produce a speed-up of ~25% on a kernel build.\n\nSubtleties -\n\n UML uses sigsetjmp/siglongjmp to switch contexts. sigsetjmp has been\n wrapped in a save_flags-like macro which remembers the interrupt state at\n setjmp time, and restores it when it is longjmp-ed back to.\n\n The enable_signals function has to loop because the IRQ handler\n disables interrupts before returning. enable_signals has to return with\n signals enabled, and signals may come in between the disabling and the\n return to enable_signals. So, it loops for as long as there are pending\n signals, ensuring that signals are enabled when it finally returns, and\n that there are no pending signals that need to be dealt with.\n\nSigned-off-by: Jeff Dike \u003cjdike@addtoit.com\u003e\nCc: Paolo \u0027Blaisorblade\u0027 Giarrusso \u003cblaisorblade@yahoo.it\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "09ee011eb322c2072ec184a88763c250a5485d8b", "tree": "ea13731ab3d7fe143b27b0f060956b3cec0f727a", "parents": [ "abaf69773d8dda98b917d94c07757f6520da7bec" ], "author": { "name": "Jeff Dike", "email": "jdike@addtoit.com", "time": "Wed Jan 18 17:42:48 2006 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Wed Jan 18 19:20:20 2006 -0800" }, "message": "[PATCH] uml: eliminate some globals\n\nStop using global variables to hold the file descriptor and offset used to map\nthe skas0 stubs.
