The result is a total failure of the JRE due to LDT selectors not working properly. This one took a long time to rear up because LDT usage is not very common, but the bug is quite serious. It got introduced along with another bug, already fixed, by 75b8bb3e56ca09a467fbbe5229bc68627f7445be Signed-off-by: Zachary Amsden Cc: Ingo Molnar Cc: Glauber de Oliveira Costa Cc: Signed-off-by: Linus Torvalds --- diff --git a/arch/x86/kernel/vmi_32.c b/arch/x86/kernel/vmi_32.c index 6ca515d..edfb09f 100644 --- a/arch/x86/kernel/vmi_32.c +++ b/arch/x86/kernel/vmi_32.c @@ -235,7 +235,7 @@ static void vmi_write_ldt_entry(struct desc_struct *dt, int entry, const void *desc) { u32 *ldt_entry = (u32 *)desc; - vmi_ops.write_idt_entry(dt, entry, ldt_entry[0], ldt_entry[1]); + vmi_ops.write_ldt_entry(dt, entry, ldt_entry[0], ldt_entry[1]); } static void vmi_load_sp0(struct tss_struct *tss,
