Hi Everyone!
How can we make a socket() system call from a linux module executing in kernel space?
If any one knows, kindly tell me. It will be great.
I want to use the socket interface in linux kernel space for sending raw packets over the network.

Greetings,
Please help me with the following :
Where can I find what means exactly and how to use each of the second

requests), SIOxxx (socket IOCTL requests), TCxxx TIOxxx (terminal
IOCTL requests) ?

I encountered a variety of difficulties when implementing a system call as simple as HelloWorld example in Linux so far.
Firstly, according to the book "Linux Kernel Development Second Edition", I tried to implement a syscall in 2.6.31 but no way absolutely because 2.6.10 has a very different way... (5 Replies)

data::formvalidator::constraintsfactory
Data::FormValidator::ConstraintsFactory(3pm) User Contributed Perl Documentation Data::FormValidator::ConstraintsFactory(3pm)NAME
Data::FormValidator::ConstraintsFactory - Module to create constraints for HTML::FormValidator.
DESCRIPTION
This module contains functions to help generate complex constraints.
If you are writing new code, take a look at Data::FormValidator::Constraints::MethodsFactory instead. It's a modern alternative to what's
here, offering improved names and syntax.
SYNOPSIS
use Data::FormValidator::ConstraintsFactory qw( :set :bool );
constraints => {
param1 => make_or_constraint(
make_num_set_constraint( -1, ( 1 .. 10 ) ),
make_set_constraint( 1, ( 20 .. 30 ) ),
),
province => make_word_set_constraint( 1, "AB QC ON TN NU" ),
bid => make_range_constraint( 1, 1, 10 ),
}
BOOLEAN CONSTRAINTS
Those constraints are available by using the ":bool" tag.
make_not_constraint( $c1 )
This will create a constraint that will return the negation of the result of constraint $c1.
make_or_constraint( @constraints )
This will create a constraint that will return the result of the first constraint that return an non false result.
make_and_constraint( @constraints )
This will create a constraint that will return the result of the first constraint that return an non false result only if all constraints
returns a non-false results.
SET CONSTRAINTS
Those constraints are available by using the ":set" tag.
make_set_constraint( $res, @elements )
This will create a constraint that will return $res if the value is one of the @elements set, or the negation of $res otherwise.
The "eq" operator is used for comparison.
make_num_set_constraint( $res, @elements )
This will create a constraint that will return $res if the value is one of the @elements set, or the negation of $res otherwise.
The "==" operator is used for comparison.
make_word_set_constraint( $res, $set )
This will create a constraint that will return $res if the value is a word in $set, or the negation of $res otherwise.
make_cmp_set_constraint( $res, $cmp, @elements )
This will create a constraint that will return $res if the value is one of the @elements set, or the negation of $res otherwise.
$cmp is a function which takes two argument and should return true or false depending if the two elements are equal.
NUMERICAL LOGICAL CONSTRAINTS
Those constraints are available by using the ":num" tag.
make_clamp_constraint( $res, $low, $high )
This will create a constraint that will return $res if the value is between $low and $high bounds included or its negation otherwise.
make_lt_constraint( $res, $bound )
This will create a constraint that will return $res if the value is lower than $bound, or the negation of $res otherwise.
make_le_constraint( $res, $bound )
This will create a constraint that will return $res if the value is lower or equal than $bound, or the negation of $res otherwise.
make_gt_constraint( $res, $bound )
This will create a constraint that will return $res if the value is greater than $bound, or the negation of $res otherwise.
make_ge_constraint( $res, $bound )
This will create a constraint that will return $res if the value is greater or equal than $bound, or the negation of $res otherwise.
OTHER CONSTRAINTS
make_length_constraint($max_length)
This will create a constraint that will return true if the value has a length of less than or equal to $max_length
