This is\nrequired by various security standards such as DCID 6/3 and PCI to provide\nnon-repudiation of administrator\u0027s actions and to allow a review of past\nactions if the administrator seems to overstep their duties or if the system\nbecomes misconfigured for unknown reasons. These requirements do not make it\nnecessary to audit TTY output as well.\n\nCompared to an user-space keylogger, this approach records TTY input using the\naudit subsystem, correlated with other audit events, and it is completely\ntransparent to the user-space application (e.g. the console ioctls still\nwork).\n\nTTY input auditing works on a higher level than auditing all system calls\nwithin the session, which would produce an overwhelming amount of mostly\nuseless audit events.\n\nAdd an \"audit_tty\" attribute, inherited across fork (). Data read from TTYs\nby process with the attribute is sent to the audit subsystem by the kernel.\nThe audit netlink interface is extended to allow modifying the audit_tty\nattribute, and to allow sending explanatory audit events from user-space (for\nexample, a shell might send an event containing the final command, after the\ninteractive command-line editing and history expansion is performed, which\nmight be difficult to decipher from the TTY input alone).\n\nBecause the \"audit_tty\" attribute is inherited across fork (), it would be set\ne.g. for sshd restarted within an audited session. To prevent this, the\naudit_tty attribute is cleared when a process with no open TTY file\ndescriptors (e.g. after daemon startup) opens a TTY.\n\nSee https://www.redhat.com/archives/linux-audit/2007-June/msg00000.html for a\nmore detailed rationale document for an older version of this patch.\n\n[akpm@linux-foundation.org: build fix]\nSigned-off-by: Miloslav Trmac \u003cmitr@redhat.com\u003e\nCc: Al Viro \u003cviro@zeniv.linux.org.uk\u003e\nCc: Alan Cox \u003calan@lxorguk.ukuu.org.uk\u003e\nCc: Paul Fulghum \u003cpaulkf@microgate.com\u003e\nCc: Casey Schaufler \u003ccasey@schaufler-ca.com\u003e\nCc: Steve Grubb \u003csgrubb@redhat.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "4f27c00bf80f122513d3a5be16ed851573164534", "tree": "2abad49c1e5c93d2d8698c558eb490b99bd35b87", "parents": [ "f3dc8c189a20dc5d115b8f0d07ac620e69eff05c" ], "author": { "name": "Alan Cox", "email": "alan@lxorguk.ukuu.org.uk", "time": "Sun Jul 15 23:40:55 2007 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Mon Jul 16 09:05:46 2007 -0700" }, "message": "Improve behaviour of spurious IRQ detect\n\nCurrently we handle spurious IRQ activity based upon seeing a lot of\ninvalid interrupts, and we clear things back on the base of lots of valid\ninterrupts.\n\nUnfortunately in some cases you get legitimate invalid interrupts caused by\ntiming asynchronicity between the PCI bus and the APIC bus when disabling\ninterrupts and pulling other tricks.

This might lead to a\nsoftirq starvation when the interval is so small that the timer is\nrequeued onto the softirq pending list right away.\n\nThis problem was pointed out by Jan Kiszka. Thanks Jan !\n\nThe correct solution would be to stop the timer, when the signal is\nignored and rearm it when SIG_IGN is removed. Unfortunately this\nrequires modification in sigaction and involves non trivial sighand\nlocking. It\u0027s too late in the release cycle for such a change.\n\nFor now we just keep the timer running and enforce that the timer only\nfires every jiffie. This does not break anything as we keep the\noverrun counter correct. It adds a little inaccuracy to the\ntimer_gettime() interface, but...\n\nThe more complex change is necessary anyway to fix another short\ncoming of the current implementation, which I discovered while looking\nat this problem: A pending signal is discarded when SIG_IGN is set. In\ncase that a posixtimer signal is pending then it is discarded as well,\nbut when SIG_IGN is removed later nothing rearms the timer.

If there were races in the optimistic wait, of a preemption\nevent scheduled the process away, we simply re-synchronize, and start\nover.\n\nSo the code now looks like this:\n\n\trepeat:\n\t\t/* Unlocked, optimistic looping! */\n\t\trq \u003d task_rq(p);\n\t\twhile (task_running(rq, p))\n\t\t\tcpu_relax();\n\n\t\t/* Get the *real* values */\n\t\trq \u003d task_rq_lock(p, \u0026flags);\n\t\trunning \u003d task_running(rq, p);\n\t\tarray \u003d p-\u003earray;\n\t\ttask_rq_unlock(rq, \u0026flags);\n\n\t\t/* Check them.. */\n\t\tif (unlikely(running)) {\n\t\t\tcpu_relax();\n\t\t\tgoto repeat;\n\t\t}\n\n\t\t/* Preempted away?

Both the runqueue used, and the \"task_running()\"\ncheck might be the wrong tests, but they won\u0027t oops - they just mean\nthat we could possibly get the wrong results due to lack of locking and\nexit the loop early in the case of a race condition.\n\nSo once we\u0027ve exited the loop, we then get the proper (and careful) rq\nlock, and check the running/runnable state _safely_. And if it turns\nout that our quick-and-dirty and unsafe loop was wrong after all, we\njust go back and try it all again.\n\n(The patch also adds a lot of comments, which is the actual bulk of it\nall, to make it more obvious why we can do these things without holding\nthe locks).\n\nThanks to Miklos for all the testing and tracking it down.\n\nTested-by: Miklos Szeredi \u003cmiklos@szeredi.hu\u003e\nAcked-by: Ingo Molnar \u003cmingo@elte.hu\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "a0f98a1cb7d27c656de450ba56efd31bdc59065e", "tree": "8ff6c211cd190aa6152e8ef4bd9f142277ed4a9f", "parents": [ "4cc21505a09354ade787de368bd697a1bba3b213" ], "author": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Sun Jun 17 18:37:45 2007 +0200" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Mon Jun 18 11:52:55 2007 -0700" }, "message": "sched: fix SysRq-N (normalize RT tasks)\n\nGene Heskett reported the following problem while testing CFS: SysRq-N\nis not always effective in normalizing tasks back to SCHED_OTHER.\n\nThe reason for that turns out to be the following bug:\n\n - normalize_rt_tasks() uses for_each_process() to iterate through all\n tasks in the system.
