ethtool: Use kcalloc instead of kmalloc for ethtool_get_strings

2015-10-15T02:00:20Z

It seems that kernel memory can leak into userspace by a kmalloc, ethtool_get_strings, then copy_to_user sequence. Avoid this by using kcalloc to zero fill the copied buffer. Signed-off-by: Joe Perches Acked-by: Ben Hutchings Signed-off-by: David S. Miller

Revert "net: core: 'ethtool' issue with querying phy settings"

2015-06-01T21:43:50Z

This reverts commit f96dee13b8e10f00840124255bed1d8b4c6afd6f. It isn't right, ethtool is meant to manage one PHY instance per netdevice at a time, and this is selected by the SET command. Therefore by definition the GET command must only return the settings for the configured and selected PHY. Reported-by: Ben Hutchings Signed-off-by: David S. Miller

net: core: 'ethtool' issue with querying phy settings

2015-05-22T20:14:17Z

When trying to configure the settings for PHY1, using commands like 'ethtool -s eth0 phyad 1 speed 100', the 'ethtool' seems to modify other settings apart from the speed of the PHY1, in the above case. The ethtool seems to query the settings for PHY0, and use this as the base to apply the new settings to the PHY1. This is causing the other settings of the PHY 1 to be wrongly configured. The issue is caused by the '_ethtool_get_settings()' API, which gets called because of the 'ETHTOOL_GSET' command, is clearing the 'cmd' pointer (of type 'struct ethtool_cmd') by calling memset. This clears all the parameters (if any) passed for the 'ETHTOOL_GSET' cmd. So the driver's callback is always invoked with 'cmd->phy_address' as '0'. The '_ethtool_get_settings()' is called from other files in the 'net/core'. So the fix is applied to the 'ethtool_get_settings()' which is only called in the context of the 'ethtool'.
