| 2 | * INET An implementation of the TCP/IP protocol suite for the LINUX |
| 3 | * operating system. INET is implemented using the BSD Socket |
| 4 | * interface as the means of communication with the user level. |
| 5 | * |
| 6 | * This file implements the various access functions for the |
| 7 | * PROC file system. It is mainly used for debugging and |
| 8 | * statistics. |

Linus Torvalds | 1da177e | 2005-04-16 15:20:36 -0700 | [diff] [blame] | 10 | * Authors: Fred N. van Kempen, <waltje@uWalt.NL.Mugnet.ORG> |
| 11 | * Gerald J. Heim, <heim@peanuts.informatik.uni-tuebingen.de> |
| 12 | * Fred Baumgarten, <dc6iq@insu1.etec.uni-karlsruhe.de> |
| 13 | * Erik Schoenfelder, <schoenfr@ibr.cs.tu-bs.de> |
| 14 | * |
| 15 | * Fixes: |
| 16 | * Alan Cox : UDP sockets show the rxqueue/txqueue |
| 17 | * using hint flag for the netinfo. |
| 18 | * Pauline Middelink : identd support |
| 19 | * Alan Cox : Make /proc safer. |
| 20 | * Erik Schoenfelder : /proc/net/snmp |
| 21 | * Alan Cox : Handle dead sockets properly. |
| 22 | * Gerhard Koerting : Show both timers |
| 23 | * Alan Cox : Allow inode to be NULL (kernel socket) |
| 24 | * Andi Kleen : Add support for open_requests and |
| 25 | * split functions for more readibility. |
| 26 | * Andi Kleen : Add support for /proc/net/netstat |
| 27 | * Arnaldo C. Melo : Convert to seq_file |
