During this time, no one should enable\nlocal IRQ and some operations which usually are not allowed with\nIRQ disabled, e.g. operations which might sleep or require\ncommunications with other processors, are allowed.\n\nlockdep tracked this with early_boot_irqs_off/on() callbacks.\nAs other subsystems need this information too, move it to\ninit/main.c and make it generally available.  While at it,\ntoggle the boolean to early_boot_irqs_disabled instead of\nenabled so that it can be initialized with %false and %true\nindicates the exceptional condition.\n\nSigned-off-by: Tejun Heo \u003ctj@kernel.org\u003e\nAcked-by: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nAcked-by: Pekka Enberg \u003cpenberg@kernel.org\u003e\nCc: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\nLKML-Reference: \u003c20110120110635.GB6036@htj.dyndns.org\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n"

      "message": "ring-buffer: Bind time extend and data events together\n\nWhen the time between two timestamps is greater than\n2^27 nanosecs (~134 ms) a time extend event is added that extends\nthe time difference to 59 bits (~18 years). This is due to\nevents only having a 27 bit field to store time.\n\nCurrently this time extend is a separate event. We add it just before\nthe event data that is being written to the buffer. But before\nthe event data is committed, the event data can also be discarded (as\nwith the case of filters). But because the time extend has already been\ncommitted, it will stay in the buffer.\n\nIf lots of events are being filtered and no event is being\nwritten, then every 134ms a time extend can be added to the buffer\nwithout any data attached. To keep from filling the entire buffer\nwith time extends, a time extend will never be the first event\nin a page because the page timestamp can be used. Time extends can\nonly fill the rest of a page with some data at the beginning.\n\nThis patch binds the time extend with the data. The difference here\nis that the time extend is not committed before the data is added.\nInstead, when a time extend is needed, the space reserved on\nthe ring buffer is the time extend + the data event size. The\ntime extend is added to the first part of the reserved block and\nthe data is added to the second. The time extend event is passed\nback to the reserver, but since the reserver also uses a function\nto find the data portion of the reserved block, no changes to the\nring buffer interface need to be made.\n\nWhen a commit is discarded, we now remove both the time extend and\nthe event. With this approach no more than one time extend can\nbe in the buffer in a row. Data must always follow a time extend.\n\nThanks to Mathieu Desnoyers for suggesting this idea.\n\nSuggested-by: Mathieu Desnoyers \u003cmathieu.desnoyers@efficios.com\u003e\nCc: Thomas Gleixner \u003ctglx@linutronix.de\u003e\nSigned-off-by: Steven Rostedt \u003crostedt@goodmis.org\u003e\n"

      "message": "llseek: automatically add .llseek fop\n\nAll file_operations should get a .llseek operation so we can make\nnonseekable_open the default for future file operations without a\n.llseek pointer.\n\nThe three cases that we can automatically detect are no_llseek, seq_lseek\nand default_llseek. For cases where we can we can automatically prove that\nthe file offset is always ignored, we use noop_llseek, which maintains\nthe current behavior of not returning an error from a seek.\n\nNew drivers should normally not use noop_llseek but instead use no_llseek\nand call nonseekable_open at open time.  Existing drivers can be converted\nto do the same when the maintainer knows for certain that no user code\nrelies on calling seek on the device file.\n\nThe generated code is often incorrectly indented and right now contains\ncomments that clarify for each added line why a specific variant was\nchosen. In the version that gets submitted upstream, the comments will\nbe gone and I will manually fix the indentation, because there does not\nseem to be a way to do that using coccinelle.\n\nSome amount of new code is currently sitting in linux-next that should get\nthe same modifications, which I will do at the end of the merge window.\n\nMany thanks to Julia Lawall for helping me learn to write a

      "message": "ring-buffer: Fix typo of time extends per page\n\nTime stamps for the ring buffer are created by the difference between\ntwo events. Each page of the ring buffer holds a full 64 bit timestamp.\nEach event has a 27 bit delta stamp from the last event. The unit of time\nis nanoseconds, so 27 bits can hold ~134 milliseconds. If two events\nhappen more than 134 milliseconds apart, a time extend is inserted\nto add more bits for the delta. The time extend has 59 bits, which\nis good for ~18 years.\n\nCurrently the time extend is committed separately from the event.\nIf an event is discarded before it is committed, due to filtering,\nthe time extend still exists. If all events are being filtered, then\nafter ~134 milliseconds a new time extend will be added to the buffer.\n\nThis can only happen till the end of the page. Since each page holds\na full timestamp, there is no reason to add a time extend to the\nbeginning of a page. Time extends can only fill a page that has actual\ndata at the beginning, so there is no fear that time extends will fill\nmore than a page without any data.\n\nWhen reading an event, a loop is made to skip over time extends\nsince they are only used to maintain the time stamp and are never\ngiven to the caller. As a paranoid check to prevent the loop running\nforever, with the knowledge that time extends may only fill a page,\na check is made that tests the iteration of the loop, and if the\niteration is more than the number of time extends that can fit in a page\na warning is printed and the ring buffer is disabled (all of ftrace\nis also disabled with it).\n\nThere is another event type that is called a TIMESTAMP which can\nhold 64 bits of data in the theoretical case that two events happen\n18 years apart. This code has not been implemented, but the name\nof this event exists, as well as the structure for it. The\nsize of a TIMESTAMP is 16 bytes, where as a time extend is only\n8 bytes. The macro used to calculate how many time extends can fit on\na page used the TIMESTAMP size instead of the time extend size\ncutting the amount in half.\n\nThe following test case can easily trigger the warning since we only\nneed to have half the page filled with time extends to trigger the\nwarning:\n\n # cd /sys/kernel/debug/tracing/\n # echo function \u003e current_tracer\n # echo \u0027common_pid \u003c 0\u0027 \u003e events/ftrace/function/filter\n # echo \u003e trace\n # echo 1 \u003e trace_marker\n # sleep 120\n # cat trace\n\nEnabling the function tracer and then setting the filter to only trace\nfunctions where the process id is negative (no events), then clearing\nthe trace buffer to ensure that we have nothing in the buffer,\nthen write to trace_marker to add an event to the beginning of a page,\nsleep for 2 minutes (only 35 seconds is probably needed, but this\nguarantees the bug), and then finally reading the trace which will\ntrigger the bug.\n\nThis patch fixes the typo and prevents the false positive of that warning.\n\nReported-by: Hans J.

But this assumption breaks\nwhen you use lseek() on the file. The state machine gets out of sync\nand the t_show() may use the wrong pointer and cause a kernel oops.\n\nLuckily, this will only kill the app that does the lseek, but the app\ndies while holding a mutex. This prevents anyone else from using the\nset_ftrace_filter file (or any other function tracing file for that matter).\n\nA real fix for this is to rewrite the code, but that is too much for\na -rc release or stable. This patch simply disables llseek on the\nset_ftrace_filter() file for now, and we can do the proper fix for the\nnext major release.\n\nReported-by: Robert Swiecki \u003cswiecki@google.com\u003e\nCc: Chris Wright \u003cchrisw@sous-sol.org\u003e\nCc: Tavis Ormandy \u003ctaviso@google.com\u003e\nCc: Eugene Teo \u003ceugene@redhat.com\u003e\nCc: vendor-sec@lst.de\nCc: \u003cstable@kernel.org\u003e\nSigned-off-by: Steven Rostedt \u003crostedt@goodmis.org\u003e\n"

      "message": "ring-buffer: Place duplicate expression into a single function\n\nWhile discussing the strictness of the 80 character limit on the\nKernel Summit Discussion mailing list, I showed examples that I\nbroke that limit slightly with some algorithms. In discussing with\nJohn Linville, what looked better, I realized that two of the\n80 char breaking culprits were an identical expression.\n\nAs a clean up, this patch moves the identical expression into its\nown helper function and that is used instead. As a side effect,\nthe offending code is now under the 80 character limit. :-)\n\nThis clean up code also changes the expression from\n\n\t(A - B) - C  to  A - (B + C)\n\nThis makes the code look a little nicer too.\n\nCc: John W.
