指向整数转换的指针不兼容,该整数从'struct net *'分配给'u32'(又名'unsigned int')

我想要的是:

要将网络名称空间选项添加到execsnoop bcc工具,以仅跟踪具有指定网络名称空间的日志,就像我们在许多其他bcc工具中使用filter PID选项一样。例如:execsnoop -N“ ns_id”

我在做什么:

int syscall__execve(struct pt_regs *ctx,
    const char __user *filename,
    const char __user *const __user *__argv,
    const char __user *const __user *__envp)
{
    // create data here and pass to submit_arg to save stack space (#555)
    //int ret = PT_REGS_RC(ctx);
    struct data_t data = {};
    struct task_struct *task;
    struct nsproxy *nsproxy;
    struct net *net;
    //struct mnt_namespace *mnt_ns;

    data.pid = bpf_get_current_pid_tgid() >> 32;

    u32 net_ns_inum = 0;
    //net = (struct net *)get_net_ns_by_pid(data.pid); //
       //net_ns_inum = (uintptr_t)net;


    task = (struct task_struct *)bpf_get_current_task();
    // Some kernels, like Ubuntu 4.13.0-generic, return 0
    // as the real_parent->tgid.
    // We use the get_ppid function as a fallback in those cases. (#1883)

    data.ppid = task->real_parent->tgid;

    net = task->nsproxy->net_ns;
    FILTER_NETNS

    data.netns =  (uintptr_t)net; //here have to perform casting

I have added #include </usr/include/stdin.h> but getting the warning though include <bits/libc-header-start.h> is present in stdint.h file:

In file included from /virtual/main.c:8:
/usr/include/stdint.h:26:10: fatal error: 'bits/libc-header-start.h' file not found
#include <bits/libc-header-start.h>
         ^~~~~~~~~~~~~~~~~~~~~~~~~~

如果我解决这一问题,它会继续生成其他丢失的头文件错误。
