Knowledge of Protocols
by Mohit . July 10, 2015

July 10, 2015

Hi, I have just finished C & linux application programming with a tinge of socket programming. I would like to know what do statements like the following mean - "Have knowledge of Protocols such as TCP/IP, IPSec, IPV6 or SSL" Does it mean to have a theoretical view of the facets which constitute the protocol which can be done by reading RFC or does it also mean to have implementation knowledge (code understanding) as well. I am not very clear about this statement which is generally used quite often. Secondly, it the latter understanding is correct (Theory - RFC + Implementation - Code) then where to look for the code which deals with a particular protocol ? Thanks !

Formal Apology
by nick July 9, 2015

July 9, 2015

Greetings All, I am formally apologizing for last year. After reading back other it all I can state is wow no wonder I was banned, not only did I not listen but all my patches were not tested. All I can state is I am so sorry and really feel stupid about so much that I feel like hitting my head against the wall a few times. In addition I cannot even believe I was that stupid and arrogant. To be honest I am surprised I wasn't banned a few weeks earlier :((((. Sorry, Nick

Am trying to reserve memory using the kernel parameter "memmap=66M$0x3b000000" on Qemu but it happens that the kernel does not boot. I get a panic with the error : kernel not syncing: Out of memory and not killable processes Is there something I am missing ?Should I use some options when building the kernel to allow this command line option ? Cheers, Asla

is there a way to register for processes state changes from userspace ?
by Ramon Fried July 9, 2015

July 9, 2015

Hi. I'm developing an application that needs to know if any of its clients (different processes) terminated or got killed by a signal. Currently I'm implementing it by looking at the specific PID procfs directory. Is there a better way to achieve that ? Something like netlink notifications for subscribed processes will be great... Thanks.

How to handle float-point operations
by 慕冬亮 July 9, 2015

I know there are rarely float-point operations! What's the exception? In the linux kernel, how does it handle the float-point operations in the userland? - mudongliang

Message not appearing in mesg
by Sébastien Hinderer July 7, 2015

Dear all, I have a module that uses pr_debug at init. Although the module is successfully loaded, the message appears neither in dmesg, nor at the console. I tried toprint a 8 to /proc/sys/kernel/printk but that does not change anything. Any hint would be warmly appreciated. Thanks! Sébastien.
