well in fact, i wanted to use my local network card's start_xmit function. so i made a function ptr to the memory region where the function resided. when i call the function with the appropriate arguments, i get a kernel oops that complains about "Unable to handle kernel paging request at virtual address ...". well is it actually possible to call that function directly to instruct the NIC to deliver a packet? if yes, how would i do that? calling the function doesnt work as described above. thank you threadhead ><threadhead@web.de> writes: >> hello list, >> >> i am using the 2.6 kernel series and would like to make use exported functions >> that are listed in /proc/kallsyms. >> >> simply using a LKM and call a function listed there results in >> 'implicit declaration of ...'. > >That means that the compiler found a use of the function before you >declared it.
