From 612a94d6f24eb2427eabf554392080302da664dd Mon Sep 17 00:00:00 2001 From: Rick Jones Date: Mon, 14 Nov 2011 08:13:25 +0000 Subject: Sweep the last of the active .get_drvinfo floors under ethernet/ This round of floor sweeping converts strncpy calls in various .get_drvinfo routines to the preferred strlcpy. It also does a modicum of other cleaning in those routines. Signed-off-by: Rick Jones Signed-off-by: David S.

This occurs because the general practice in user space to query stats is to issue a ETHTOOL_GSSET cmd to learn the buffer size needed, allocate the buffer, then call ETHTOOL_GSTIRNGS and ETHTOOL_GSTATS. If the number of real_num_queues is changed or flow control attributes are changed after ETHTOOL_GSSET but before the ETHTOOL_GSTRINGS/ETHTOOL_GSTATS a user space buffer overrun occurs. To fix the overrun always return the max buffer size needed from get_sset_count() then return all strings and stats from get_strings()/get_ethtool_stats(). This _will_ change the output from the ioctl() call which could break applications and script parsing in theory. I believe these changes should not break existing tools because the only changes will be more {tx|rx}_queues and the {tx|rx}_pb_* stats will always be returned. Existing scripts already need to handle changing number of queues because this occurs today depending on system and current features. The {tx|rx}_pb_* stats are at the end of the output and should be handled by scripts today regardless. Finally get_ethtool_stats and get_strings are free-form outputs tools parsing these outputs should be defensive anyways. In the end these updates are better then having a tool segfault because of a buffer overrun.
