Kernel level exception handling in Linux 2.1.8
Kernel level exception handling in Linux
Commentary by Joerg Pommnitz <joerg@raleigh.ibm.com>
When a process runs in kernel mode, it often has to access user
mode memory whose address has been passed by an untrusted program.
When a process runs in kernel mode, it often has to access user
mode memory whose address has been passed by an untrusted program.
To protect itself the kernel has to verify this address.

This function verified that the memory area starting at address
'addr' and of size 'size' was accessible for the operation specified

It only failed for a few buggy programs. In some kernel profiling
tests, this normally unneeded verification used up a considerable
amount of time.
To overcome this situation, Linus decided to let the virtual memory
To overcome this situation, Linus decided to let the virtual memory

How does this work?

regs is a pointer to the saved registers on the stack, error_code

do_page_fault first obtains the unaccessible address from the CPU
control register CR2. If the address is within the virtual address
space of the process, the fault probably occurred, because the page
was not swapped in, write protected or something similar. However,
we are interested in the other case: the address is not valid, there
is no vma that contains this address. In this case, the kernel jumps
to the bad_area label.
