From Bugzilla Helper: User-Agent: Mozilla/4.0 (compatible; MSIE 5.5; Windows NT 5.0; T312461; .NET CLR 1.0.3705) Description of problem: Installed one or more isdn cards, using driver hisax. /proc/net/dev reports at transmit only data for the master channel, but not for slaves. Recieve is OK. All other devices (eth) are OK. Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1.Use ISDN with hisax driver (also other drivers???) 2.Put some load on the ISDN 3.Run "cat /proc/net/dev | grep "ippp0" 4.Recieve is OK, transmit not. Actual Results: Transmit is wrong Expected Results: Should be right....:-) Additional info:
Notified also fritz@isdn4linux.de and keil@isdn4linux.de authors of isdn and hisax driver
I have seen cases where the byte counts (both transmit and receive) in /proc/dev/net go up to 2^32-1 (over 4 gig) then stop counting. I'm not sure whether this is coming from the driver or not; the code that prints this is in /usr/src/linux/net/core/dev.c: #ifdef CONFIG_PROC_FS static int sprintf_stats(char *buffer, struct net_device *dev) { struct net_device_stats *stats = (dev->get_stats ? dev->get_stats(dev): NULL) ; int size; if (stats) size = sprintf(buffer, "%6s:%8lu %7lu %4lu %4lu %4lu %5lu %10lu %9lu %8lu %7lu %4lu %4lu %4lu %5lu %7lu %10lu\n", dev->name, stats->rx_bytes, stats->rx_packets, stats->rx_errors, stats->rx_dropped + stats->rx_missed_errors, stats->rx_fifo_errors, stats->rx_length_errors + stats->rx_over_errors + stats->rx_crc_errors + stats->rx_frame_errors, stats->rx_compressed, stats->multicast, stats->tx_bytes, stats->tx_packets, stats->tx_errors, stats->tx_dropped, stats->tx_fifo_errors, stats->collisions, stats->tx_carrier_errors + stats->tx_aborted_errors + stats->tx_window_errors + stats->tx_heartbeat_errors, stats->tx_compressed); else size = sprintf(buffer, "%6s: No statistics available.\n", dev- >name); return size; } I'm suspicious of the "%8lu" format. I looked at a few of the drivers and the stats do appear to be 64 bits.
The bug I reported concerns only ISDN connections with slave configuration. However the comment from znmeb@aracnet.com is interesting too... I did not get any answers until today. I have some ISDN backup connection with a master channel and many slave channels. However the transmit (UP) is reporting only the bytes of the master channel, even so the line is actually transmitting much more. Maybe the designers of isdn4linux never thought of this possibility??
Thanks for the bug report. However, Red Hat no longer maintains this version of the product. Please upgrade to the latest version and open a new bug if the problem persists. The Fedora Legacy project (http://fedoralegacy.org/) maintains some older releases, and if you believe this bug is interesting to them, please report the problem in the bug tracker at: http://bugzilla.fedora.us/
