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.

In the\nnormal situation for an IRQ driven serial port at typical speeds the\nbehaviour is pretty much the same, two buffers end up allocated and the\nkernel cycles between them as before.\n\nWhen there are delays or at high speed we now behave far better as the\nbuffer pool can grow a bit rather than lose characters. This also means\nthat we can operate at higher speeds reliably.\n\nFor drivers that receive characters in blocks (DMA based, USB and\nespecially virtualisation) the layer allows a lot of driver specific\ncode that works around the tty layer with private secondary queues to be\nremoved. The IBM folks need this sort of layer, the smart serial port\npeople do, the virtualisers do (because a virtualised tty typically\noperates at infinite speed rather than emulating 9600 baud).\n\nFinally many drivers had invalid and unsafe attempts to avoid buffer\noverflows by directly invoking tty methods extracted out of the innards\nof work queue structs. These are no longer needed and all go away. That\nfixes various random hangs with serial ports on overflow.\n\nThe other change in here is to optimise the receive_room path that is\nused by some callers. It turns out that only one ldisc uses receive room\nexcept asa constant and it updates it far far less than the value is\nread. We thus make it a variable not a function call.\n\nI expect the code to contain bugs due to the size alone but I\u0027ll be\nwatching and squashing them and feeding out new patches as it goes.\n\nBecause the buffers now dynamically expand you should only run out of\nbuffering when the kernel runs out of memory for real. That means a lot of\nthe horrible hacks high performance drivers used to do just aren\u0027t needed any\nmore.\n\nDescription:\n\ntty_insert_flip_char is an old API and continues to work as before, as does\ntty_flip_buffer_push() [this is why many drivers dont need modification]. It\ndoes now also return the number of chars inserted\n\nThere are also\n\ntty_buffer_request_room(tty, len)\n\nwhich asks for a buffer block of the length requested and returns the space\nfound. This improves efficiency with hardware that knows how much to\ntransfer.\n\nand tty_insert_flip_string_flags(tty, str, flags, len)\n\nto insert a string of characters and flags\n\nFor a smart interface the usual code is\n\n len \u003d tty_request_buffer_room(tty, amount_hardware_says);\n tty_insert_flip_string(tty, buffer_from_card, len);\n\nMore description!\n\nAt the moment tty buffers are attached directly to the tty. This is causing a\nlot of the problems related to tty layer locking, also problems at high speed\nand also with bursty data (such as occurs in virtualised environments)\n\nI\u0027m working on ripping out the flip buffers and replacing them with a pool of\ndynamically allocated buffers. This allows both for old style \"byte I/O\"\ndevices and also helps virtualisation and smart devices where large blocks of\ndata suddenely materialise and need storing.\n\nSo far so good. Lots of drivers reference tty-\u003eflip.*. Several of them also\ncall directly and unsafely into function pointers it provides. This will all\nbreak. Most drivers can use tty_insert_flip_char which can be kept as an API\nbut others need more.\n\nAt the moment I\u0027ve added the following interfaces, if people think more will\nbe needed now is a good time to say\n\n int tty_buffer_request_room(tty, size)\n\nTry and ensure at least size bytes are available, returns actual room (may be\nzero). At the moment it just uses the flipbuf space but that will change.\nRepeated calls without characters being added are not cumulative. (ie if you\ncall it with 1, 1, 1, and then 4 you\u0027ll have four characters of space. The\nother functions will also try and grow buffers in future but this will be a\nmore efficient way when you know block sizes.\n\n int tty_insert_flip_char(tty, ch, flag)\n\nAs before insert a character if there is room. Now returns 1 for success, 0\nfor failure.\n\n int tty_insert_flip_string(tty, str, len)\n\nInsert a block of non error characters. Returns the number inserted.\n\n int tty_prepare_flip_string(tty, strptr, len)\n\nAdjust the buffer to allow len characters to be added. Returns a buffer\npointer in strptr and the length available. This allows for hardware that\nneeds to use functions like insl or mencpy_fromio.\n\nSigned-off-by: Alan Cox \u003calan@redhat.com\u003e\nCc: Paul Fulghum \u003cpaulkf@microgate.com\u003e\nSigned-off-by: Hirokazu Takata \u003ctakata@linux-m32r.org\u003e\nSigned-off-by: Serge Hallyn \u003cserue@us.ibm.com\u003e\nSigned-off-by: Jeff Dike \u003cjdike@addtoit.com\u003e\nSigned-off-by: John Hawkes \u003chawkes@sgi.com\u003e\nSigned-off-by: Martin Schwidefsky \u003cschwidefsky@de.ibm.com\u003e\nSigned-off-by: Adrian Bunk \u003cbunk@stusta.de\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "a885c8c4316e1c1d2d2c8755da3f3d14f852528d", "tree": "e4f4e7a7657c0944d11c259f8f17ffcd6b2da0f5", "parents": [ "5b0ed2c64d8fdafb5fcfb3baabdd288628b1ff9b" ], "author": { "name": "Christoph Hellwig", "email": "hch@lst.de", "time": "Sun Jan 08 01:02:50 2006 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Sun Jan 08 20:13:54 2006 -0800" }, "message": "[PATCH] Add block_device_operations.getgeo block device method\n\nHDIO_GETGEO is implemented in most block drivers, and all of them have to\nduplicate the code to copy the structure to userspace, as well as getting\nthe start sector.

The intent is to make it obvious\nthat an IRQ can\u0027t exist without an open file descriptor.\n\nchan_enable will now open the channel, and when both opening and IRQ\nregistration are desired, this should be used. Opening only is done for the\ninitial console, so that interface still needs to exist.\n\nThe free_irqs_later interface is now gone. It was intended to avoid freeing\nan IRQ while it was being processed. It did this, but it didn\u0027t eliminate the\npossiblity of free_irq being called from an interrupt, which is bad. In its\nplace is a list of irqs to be freed, which is processed by the signal handler\njust before exiting. close_one_chan now disables irqs.\n\nWhen a host device disappears, it is just closed, and that disables IRQs.\n\nThe device id registered with the IRQ is now the chan structure, not the tty.\nThis is because the interrupt arrives on a descriptor associated with the\nchannel. This caused equivalent changes in the arguments to line_timer_cb.\nline_disable is gone since it is not used any more.\n\nThe count field in the line structure is gone. tty-\u003ecount is used instead.\n\nThe complicated logic in sigio_handler with freeing IRQs when necessary and\nmaking sure its idea of the next irq is correct is now much simpler.

While sysrq-t\ndoes the same thing, sysrq-t shows *all* threads stacks. It also doesn\u0027t work\nright now. In the future, I thought it might be acceptable to make this show\nall pids stacks, but perhaps leaving well enough alone and just using sysrq-t\nwould be okay. For now, upon receiving the stack command, UML switches\ncontext to that thread, dumps its registers, and then switches context back to\nthe original thread. Since UML compacts all threads into one of 4 host\nthreads, this sort of mechanism could be expanded in the future to include\nother debugging helpers that sysrq does not cover.\n\nNote by jdike - The main benefit to this is that it brings an arbitrary thread\nback into context, where it can be examined by gdb. The fact that it dumps it\nstack is secondary. This provides the capability to examine a sleeping\nthread, which has existed in tt mode, but not in skas mode until now.\n\nAlso, the other threads, that sysrq doesn\u0027t cover, can be gdb-ed directly\nanyway.\n\nSigned-off-by: Allan Graves\u003callan.graves@gmail.com\u003e\nSigned-off-by: Jeff Dike \u003cjdike@addtoit.com\u003e\nCc: Paolo 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": "09ace81c1d737bcbb2423db235ac980cac4d5de9", "tree": "d31987b15d57429bd40843c02b2283b8e2d90cb0", "parents": [ "75e5584c89d213d6089f64f22cd899fb172e4c95" ], "author": { "name": "Jeff Dike", "email": "jdike@addtoit.com", "time": "Sat Sep 03 15:57:46 2005 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@evo.osdl.org", "time": "Mon Sep 05 00:06:23 2005 -0700" }, "message": "[PATCH] uml: add host AIO support to block driver\n\nThis adds AIO support to the ubd driver.\n\nThe driver breaks a struct request into IO requests to the host, based on the\nhardware segments in the request and on any COW blocks covered by the request.\n\nThe ubd IO thread is gone, since there is now an equivalent thread in the AIO\nmodule.\n\nThere is provision for multiple outstanding requests now.
