The non-resumable errors from userspace has been able to cause kernel panics or trap loops due to the setup and handling of the queued traps once in the kernel. This patch series addresses both of these issues by preventing the panic by sending a SIGBUS error to the offending process and by zeroing the queue memory before use. Liam R. Howlett (2): sparc64: Don't panic on user mode non-resumable errors sparc64: Zero pages on allocation for mondo and error queues. arch/sparc/kernel/irq_64.c | 2 +- arch/sparc/kernel/traps_64.c | 21 +++++++++++++++++++++ 2 files changed, 22 insertions(+), 1 deletion(-) -- 2.1.4 -- To unsubscribe from this list: send the line "unsubscribe sparclinux" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
