Thanks
for the replies so far. I found a way to emulate message queues in kernel using
socket programming. I’m sharing it in case someone else finds it useful.
These steps should be easy for anyone familiar with sockets (unlike me :)) -open
a local socket: protocol=SOCK_DGRAM, family=AF_LOCAL -bind
it to the loopback address -connect
to the socket -now
you can send and receive messages [kernel_sendmsg()/kernel_recvmsg()] to/from
the socket Let
me know in case you are aware of any flaws in the above method. Thanks, Sarthak
Ray From: Sarthak Ray Hello all, I want to use message-queues in a Linux kernel module (v2.6.12.5).
However, I am unable to find any exported APIs for using message-queues in
kernel-space. In ipc/msg.c file, I see some message-queue
functions implemented such as sys_msgrcv(),
sys_msgsnd(), etc. However, these functions are not exported for use in kernel modules. Also,
they seem to be implemented for servicing user-space message-queue requests. I would appreciate any pointers towards equivalent message-queue APIs
for kernel-space. Thanks, Sarthak Ray |
