Here is some code that checks the TCP
Hi,
I am looking for the code in linux kernel that verifies the checksum of TCP
header and IP header for inbound packet. The packet supposes to be dropped
if the checksum doesn't match.
I tried tcp_input.c and ip_input.c, also with global search. But I couldn't
find any code that does this job. Ca
how about using define
page_to_phys(page) ((dma_addr_t)page_to_pfn(page) << PAGE_SHIFT)
or
virt_to_phys ()

apart from this you need to be aware of your cache type used in system

Hi Ashish,
In Kernel when enable spin_lock debugging, the code path and behavior
of spin_lock is changed.
when debugging is off, spin_lock() spin in tight loop, but in
spin_lock_debug it work as try() lock ().
So we can debug the system and find who hold the lock for long time.
Below is sequenc
