SHA-1 hash calculate in Kernel.

hi all: I built a module for calculate the SHA-1. The code is: ## #include linux/init.h #include linux/module.h #include linux/kernel.h #include linux/crypto.h #include linux/err.h #include linux/scatterlist.h MODULE_LICENSE(Dual BSD/GPL); #define SHA1_LENGTH 20 static

Process for adding a new source(driver) to linux kernel tree

HI, I wanted to know what is the process for adding a new source(say driver) to the kernel tree.I am not asking for how to add a driver ( like modifying make file, Kconfig, adding driver to staging or my_driver folder) but the process for adding it to the source tree Like : - which branch to add

Identify Beacon Frame

Hi All, I am new to kernel development. I am writing a kernel module that captures packet at the netfilter pre - routing hook. I only want to capture the BEACON FRAME. I have few queries: 1When the beacon frame comes to receiving machine do the sk_buff gets allocated? 2 How can i identify the

Re: Identify Beacon Frame

Well..from userspace application you need to register which subtype of frames you want to receive. This is done with netlink sockets. You can check hostapd/wpa_supplicant sources to see how this is done. http://w1.fi/wpa_supplicant/ I assume you are using newer kernel e.g. 3.0 onwards. Old

Avinash, Ya m talking about the WLAN. can you just throw some more light on cfg802.11 handlers. On Fri, Aug 28, 2015 at 11:24 PM, Avinash Patil avinashapa...@gmail.com wrote: Hi Gunjan, Are you talking about WLAN beacon frames? If so, you can you cfg80211 handlers to register management

Re: Identify Beacon Frame

Hi Gunjan, Are you talking about WLAN beacon frames? If so, you can you cfg80211 handlers to register management frames and once frame is received parse frame type/subtype to check if its beacon. I dont think beacon frames are delievered to netdev. Thanks, Avinash On Fri, Aug 28, 2015 at 10:51
