Try to googling for documentation about netlink socket (there isn't a lot, but you should find a pdf about it)Dear list,
I need mechanisms to implement an upcall from kernel to user. A user space application should be able to register at a particular hook. Whenever the kernel wants to signal anything to the user application, it should do the upcall. Both sides should be able to pass abitrary data back and forth as pointer to byte arrays and -- if possible -- signal the result of the call as return-value. Is this possible?
After googling, I found quite often the recommendation to read the code of the Linux coda filesystem implementation. Reading code reveals particular aspects but has not helped me understanding the full picture.
Therefore my question:
Does anybody know of any good technical documentation of up- and downcalls that not explains the concepts but gives also easy-to-understand examples.
Thanks in advance for any help!
wbr,
