If it cannot\npull any tasks away from the busiest cpu because they were pinned then the\nscheduler goes into a corner and sulks leaving the idle processors idle.\n\nF.e. If you have processor 0 busy running four tasks pinned via taskset,\nthere are none on processor 1 and one just started two processes on\nprocessor 2 then the scheduler will not move one of the two processes away\nfrom processor 2.\n\nThis patch fixes that issue by forcing the scheduler to come out of its\ncorner and retrying the load balancing by considering other processors for\nload balancing.\n\nThis patch was originally developed by John Hawkes and discussed at\n\n http://marc.theaimsgroup.com/?l\u003dlinux-kernel\u0026m\u003d113901368523205\u0026w\u003d2.\n\nI have removed extraneous material and gone back to equipping struct rq\nwith the cpu the queue is associated with since this makes the patch much\neasier and it is likely that others in the future will have the same\ndifficulty of figuring out which processor owns which runqueue.\n\nThe overhead added through these patches is a single word on the stack if\nthe kernel is configured to support 32 cpus or less (32 bit). For 32 bit\nenvironments the maximum number of cpus that can be configued is 255 which\nwould result in the use of 32 bytes additional on the stack. On IA64 up to\n1k cpus can be configured which will result in the use of 128 additional\nbytes on the stack. The maximum additional cache footprint is one\ncacheline. Typically memory use will be much less than a cacheline and the\nadditional cpumask will be placed on the stack in a cacheline that already\ncontains other local variable.\n\nSigned-off-by: Christoph Lameter \u003cclameter@sgi.com\u003e\nCc: John Hawkes \u003chawkes@sgi.com\u003e\nCc: \"Siddha, Suresh B\" \u003csuresh.b.siddha@intel.com\u003e\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: Nick Piggin \u003cnickpiggin@yahoo.com.au\u003e\nCc: Peter Williams \u003cpwil3058@bigpond.net.au\u003e\nCc: \u003cstable@kernel.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "1cc5f7142eca352109895fe20b1fc6405dd17727", "tree": "9c6b4b3204f06317c830457e091ff2c83272ea09", "parents": [ "bfa0e9a07cd31f3858239dbc93011b82780acf4b" ], "author": { "name": "Ed Swierk", "email": "eswierk@arastra.com", "time": "Mon Sep 25 16:25:36 2006 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Mon Sep 25 17:38:36 2006 -0700" }, "message": "[PATCH] load_module: no BUG if module_subsys uninitialized\n\nInvoking load_module() before param_sysfs_init() is called crashes in\nmod_sysfs_setup(), since the kset in module_subsys is not initialized yet.\n\nIn my case, net-pf-1 is getting modprobed as a result of hotplug trying to\ncreate a UNIX socket.

This is due to buggy logic in the use of\nfutex_handle_fault() and its attempt argument in a failure case.\n\nLooking at futex.c the logic is as follows:\n\n1) In futex_unlock_pi() we start w/ ret\u003d0 and we go down to the first\n futex_atomic_cmpxchg_inatomic(), where we find uval\u003d\u003d-EFAULT. We then\n jump to the pi_faulted label.\n\n2) From pi_faulted: We increment attempt, unlock the sem and hit the\n retry label.\n\n3) From the retry label, with ret still zero, we again hit EFAULT on the\n first futex_atomic_cmpxchg_inatomic(), and again goto the pi_faulted\n label.\n\n4) Again from pi_faulted: we increment attempt and enter the\n conditional, where we call futex_handle_fault.\n\n5) futex_handle_fault fails, and we goto the out_unlock_release_sem\n label.\n\n6) From out_unlock_release_sem we return, and since ret is still zero,\n we return without error, while never actually unlocking the lock.\n\nIssue #1: at the first futex_atomic_cmpxchg_inatomic() we should probably\nbe setting ret\u003d-EFAULT before jumping to pi_faulted: However in our case\nthis doesn\u0027t really affect anything, as the glibc we\u0027re using ignores the\nerror value from futex_unlock_pi().\n\nIssue #2: Look at futex_handle_fault(), its first conditional will return\n-EFAULT if attempt is \u003e\u003d 2. However, from the \"if(attempt++)\nfutex_handle_fault(attempt)\" logic above, we\u0027ll *never* call\nfutex_handle_fault when attempt is less then two. So we never get a chance\nto even try to fault the page in.\n\nThe following patch addresses these two issues by 1) Always setting ret to\n-EFAULT if futex_handle_fault fails, and 2) Removing the \u003d in\nfutex_handle_fault\u0027s (attempt \u003e\u003d 2) check.\n\nI\u0027m really not sure this is the right fix, but wanted to bring it up so\nfolks knew the issue is alive and well in the current -git tree.

The irq flags save and restore were also added to\nlocal_bh_enable, probably for injecting the trace irqs code.\n\nThis overhead is on the generic code path across all architectures. On a\nIA_64 test machine (Itanium-2 1.6 GHz) running a benchmark like netperf\u0027s\nUDP streaming test, the added overhead results in a drop of 3% in\nthroughput, as udp_sendmsg calls the local_bh_enable/disable several times.\n\nOther workloads that have heavy usages of local_bh_enable/disable could\nalso be affected.

A local user could create a program that would cause a\ncore file to be dumped into a directory they would not normally have\npermissions to write to. This could lead to a denial of service (disk\nconsumption), or allow the local user to gain root privileges.\n\nThe prctl() system call should never allow to set \"dumpable\" to the\nvalue 2. Especially not for non-privileged users.\n\nThis can be split into three cases:\n\n 1) running as root -- then core dumps will already be done as root,\n and so prctl(PR_SET_DUMPABLE, 2) is not useful\n\n 2) running as non-root w/setuid-to-root -- this is the debatable case\n\n 3) running as non-root w/setuid-to-non-root -- then you definitely\n do NOT want \"dumpable\" to get set to 2 because you have the\n privilege escalation vulnerability\n\nWith case #2, the only potential usefulness is for a program that has\ndesigned to run with higher privilege (than the user invoking it) that\nwants to be able to create root-owned root-validated core dumps. This\nmight be useful as a debugging aid, but would only be safe if the program\nhad done a chdir() to a safe directory.\n\nThere is no benefit to a production setuid-to-root utility, because it\nshouldn\u0027t be dumping core in the first place. If this is true, then the\nsame debugging aid could also be accomplished with the \"suid_dumpable\"\nsysctl.\n\nSigned-off-by: Marcel Holtmann \u003cmarcel@holtmann.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "2c16e9c888985761511bd1905b00fb271169c3c0", "tree": "e17756b3ed27b0f4953547c39cf46864cdd6f818", "parents": [ "e54695a59c278b9ff48cd4b263da7a1d392f5061" ], "author": { "name": "Arjan van de Ven", "email": "arjan@linux.intel.com", "time": "Mon Jul 10 04:45:42 2006 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Mon Jul 10 13:24:27 2006 -0700" }, "message": "[PATCH] lockdep: disable lock debugging when kernel state becomes untrusted\n\nDisable lockdep debugging in two situations where the integrity of the\nkernel no longer is guaranteed: when oopsing and when hitting a\ntainting-condition.
