Hi. I need to find and close a certain socket from kernel module. My current implementation iterates over the "allproc" list and checks every process' file descriptors list to find needed socket. But maybe there is an easier way to do this? Some nixes have "inpcbtable" which holds all the open sockets on the system. Is there anything similar in FreeBSD? And the second question: whats the correct way to close the socket which was found? My implementation: ..... mysocket = myproc->p_fd->fd_ofiles[i]->f_data; myproc->p_fd->fd_ofiles[i]->f_data = NULL; myproc->p_fd->fd_ofiles[i]->f_ops = &badfileops; soclose(mysocket); ..... The socket closes but it causes a kernel panic in 90% of cases and file descriptor doesnt actualy released (as fstat shows), but is marked as "error" (because of "badfileops" I suppose). Maybe I should acqure some mutex lock or something before starting manipulations with socket? Any exampe code will be very much appreciated. Its my first steps in fbsd kernel programming so please xcuse me for newbie questions. Taras Danko. - - - - - - - - - - - - - - - - - - - - - - contact me: email: gortaur@gmail.com icq: 166956956
