Bug #1751

Updated by tuxillo almost 12 years ago

Hi, 

 During the boot process of the livecd (latest x86_64 ISO from 
 26-April-2010) on KVM, I get the following:

 In    sys/platform/vkernel64/x86_64/trap.c line 639 there's a comment: 

 "Invalid segment selectors and out of bounds %rip's and %rsp's can be 
 set up in user mode. This causes a fault in kernel mode when the 
 kernel tries to return to user mode.    We want to get this fault so 
 that we can fix the problem here and not have to check all the 
 selectors and pointers when the user changes them." 

 Cheers, 
 Antonio Huete
