From 8a3a0ee736b9a0150c9d894f2c6cc836a62125a1 Mon Sep 17 00:00:00 2001 From: Kenji Kaneshige Date: Mon, 26 Mar 2007 09:38:42 +0900 Subject: [IA64] Fix possible invalid memory access in ia64_setup_msi_irq() The following 'if' statement in ia64_setup_msi_irq() always fails even if create_irq() returns <0 value, because variable 'irq' is defined as unsigned int. It would cause invalid memory access. irq = create_irq(); if (irq < 0) return irq; Signed-off-by: Kenji Kaneshige Signed-off-by: Tony Luck --- arch/ia64/kernel/msi_ia64.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'arch/ia64') diff --git a/arch/ia64/kernel/msi_ia64.c b/arch/ia64/kernel/msi_ia64.c index e722090..ebbeadf 100644 --- a/arch/ia64/kernel/msi_ia64.c +++ b/arch/ia64/kernel/msi_ia64.c @@ -68,7 +68,7 @@ int ia64_setup_msi_irq(struct pci_dev *pdev, struct msi_desc *desc) { struct msi_msg msg; unsigned long dest_phys_id; - unsigned int irq, vector; + int irq, vector; irq = create_irq(); if (irq < 0) -- cgit v1.1
