以上操作完成了struct socket、struct sock、struct file等的创建、初始化、关联,并最终返回socket描述符fd socket描述符fd和我们平时操作文件的文件描述符相同,那么会有一个疑问,可以看到struct file_operations socket_file_ops函数表中并没有提供write和read接口,只是看到read_iter,write_iter等接口,那么系统是如何处理...
当我们打开一个 stat 文件时(如/proc/self/stat)便会在内核空间中分配一个 seq_operations 结构体,该结构体定义于/include/linux/seq_file.h当中,只定义了四个函数指针,如下: struct seq_operations { void * (*start) (struct seq_file *m, loff_t *pos); void (*stop) (struct seq_file *m, void...
使用c语言ebpf和int _sockops(struct bpf_sock_ops *ctx)函数,map随意 我是初学者,死活写不出来,求教大佬们。

I know that 'struct proto_ops' is used to define the operations, e.g. bind/connect/accept, and every socket has a specified proto_ops. On the other hand, 'struct proto' defines new protocol and the structure also defines function pointers for accept/bind/setsockopt/getsockopt/etc. metho...
struct file_system_type *s_type:文件系统类型(也就是当前这个文件系统属于哪个类型?ext2还是fat32)要区分“文件系统”和“文件系统类型”不一样!一个文件系统类型下可以包括很多文件系统即很多的super_block。 1conststructsuper_operations *s_op;2conststructdquot_operations *dq_op; ...
