This happens if the task was in the middle of a system\ncall when the second PTRACE_ATTACH was done. The symptom is an\nunexpected SIGTRAP when the tracer thinks that only SIGSTOP should have\nbeen provoked by his ptrace calls so far.\n\nA few machines already fixed this in ptrace_disable (i386, ia64, m68k).\nBut all other machines do not, and still have this bug. On x86_64, this\nconstitutes a regression in IA32 compatibility support.\n\nSince all machines now use TIF_SYSCALL_TRACE for this, I put the\nclearing of TIF_SYSCALL_TRACE in the generic ptrace_detach code rather\nthan adding it to every other machine\u0027s ptrace_disable.\n\nSigned-off-by: Roland McGrath \u003croland@redhat.com\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "1169783085adb9ac969d21103a6885e8435f7ed3", "tree": "8d5313ef18ba821436aa838cb6f03f065049ef21", "parents": [ "4a55b45036a677fac43fe81ddf7fdcd007aaaee7" ], "author": { "name": "Peter Zijlstra", "email": "a.p.zijlstra@chello.nl", "time": "Wed Sep 05 14:32:49 2007 +0200" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Wed Sep 05 14:32:49 2007 +0200" }, "message": "sched: fix ideal_runtime calculations for reniced tasks\n\nfix ideal_runtime:\n\n - do not scale it using niced_granularity()\n it is against sum_exec_delta, so its wall-time, not fair-time.\n\n - move the whole check into __check_preempt_curr_fair()\n so that wakeup preemption can also benefit from the new logic.\n\nthis also results in code size reduction:\n\n text data bss dec hex filename\n 13391 228 1204 14823 39e7 sched.o.before\n 13369 228 1204 14801 39d1 sched.o.after\n\nSigned-off-by: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" }, { "commit": "4a55b45036a677fac43fe81ddf7fdcd007aaaee7", "tree": "86558fa9997e28194d84b997011ed91cde49746c", "parents": [ "7c92e54f6f9601cfa9d8894ee248abcf62ed9a1c" ], "author": { "name": "Peter Zijlstra", "email": "a.p.zijlstra@chello.nl", "time": "Wed Sep 05 14:32:49 2007 +0200" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Wed Sep 05 14:32:49 2007 +0200" }, "message": "sched: improve prev_sum_exec_runtime setting\n\nSecond preparatory patch for fix-ideal runtime:\n\nMark prev_sum_exec_runtime at the beginning of our run, the same spot\nthat adds our wait period to wait_runtime.
