Re: One Filesystem vnode operations declare problem.

;in '/dev/', it use the 'normarl' vop; we use 'devfs rules', it use the 'special' vop, right? If I guess right, but the kernel how to know it should use which vop? Thank you very much! Best Regards Ouyang Kai __

Re: One Filesystem vnode operations declare problem.

ors. VNODEOP_SET(ffs_specop_opv_desc); I think it is special operation vectors. But I do not know its purpose. VNODEOP_SET(ffs_fifoop_opv_desc); I think it is FIFO operation vectors. Why do those three VOP_SETs have many repeated defines? Or

Re: About 'sysctl' routine problem?

ck. So, the kernel will call sysctl_rtsock, right? in sysctl_rtsock function: case NET_RT_IFLIST: error = sysctl_iflist(af, &w); So, this time, the kernel will call sysctl_iflist finally, right? But I have some wonder how the 'sysctl' command transfer from user space to kernel space? I find the line in sysproto.h: int __sysctl __P((struct proc *, struct sysctl_args *)); I think whether the 'sysctl' is changed to '__sysctl' in kernel space? If that is right, the __sysctl is how conect with sysctl_rtsock? Thank you very much!:-) Best Regards Ouyang Kai

About 'sysctl' routine problem?

Hi guys,  In the "TCP/IP Illustrated, Volume2: The Implementation" book,there give 'ioctl' and 'sysctl' in the kernel routine.  ioctl -> sooioctl->(interface)ifioctl.  sysctl-> net_sysctl -> pr_sysctl -> ip_sysctl  Now, I can find the corresponding code about 'ioctl' routine.But, I could no

How the kernel add the devices when the kernel start

. But I do not the 'func' means what when it check SI_SUB_DRIVERS.2.

Hi Everybody,   I am a jackaroo to FreeBSD kernel. I have a question about how the kernel add all devices.   For example, in NetBSD, I can find the code in /sys/kern/init_main.c:  /* Attach pseudo-devices. */ for (pdev = pdevinit; pdev->pdev_attach != NULL; pdev++)       (*pdev->pdev_atta
