Kirill Korotaev 4286229868 [PATCH] wrong error path in dup_fd() leading to oopses in RCU ... Wrong error path in dup_fd() - it should return NULL on error, not an address of already freed memory :/ Triggered by OpenVZ stress test suite. What is interesting is that it was causing different oopses in RCU like below: Call Trace: [<c013492c>] rcu_do_batch+0x2c/0x80 [<c0134bdd>] rcu_process_callbacks+0x3d/0x70 [<c0126cf3>] tasklet_action+0x73/0xe0 [<c01269aa>] __do_softirq+0x10a/0x130 [<c01058ff>] do_softirq+0x4f/0x60 ======================= [<c0113817>] smp_apic_timer_interrupt+0x77/0x110 [<c0103b54>] apic_timer_interrupt+0x1c/0x24 Code: Bad EIP value. <0>Kernel panic - not syncing: Fatal exception in interrupt Signed-Off-By: Pavel Emelianov <xemul@sw.ru> Signed-Off-By: Dmitry Mishin <dim@openvz.org> Signed-Off-By: Kirill Korotaev <dev@openvz.org> Signed-Off-By: Linus Torvalds <torvalds@osdl.org>		2006-03-31 12:25:46 -08:00
