* Fix attribute list size in do_get_nl_link()Wang Xin2020-11-171-1/+1
| | | | | | | | | | | | | | | | | | The function do_get_nl_link() retrieves attributes from the response RTM_NEWLINK. But it calculates the attribute list size with the wrong structure struct ifaddrmsg. According to man 7 rtnetlink, RTM_NEWLINK message uses struct ifinfomsg instead of struct ifaddrmsg. This causes that additional 8 bytes are parsed and garbage attributes might be retrieved. One of consequences is that the message will be dropped if the garbage attribute is IFLA_IFNAME and contains an invalid interface name. To fix this issue, use struct ifinfomsg to calculate the size of attribute list for RTM_NEWLINK.

* Add interface to retrieve link statisticsLeo Ruan2018-08-082-0/+41
| | | | | | | | | | | | | | | | This commit adds an interface to get the statistics (64-bits) from CAN interface. See more information from /usr/include/linux/if_link.h where defines the struct rtnl_link_stats64. Compare to the rtnl_link_stats, rtnl_link_stats64 was introduced since linux kernel 2.6. After that the rtnl_link_stats is synchronous with struct rtnl_link_stats64 by truncating each member from 64 bits to 32 bits. Actually, the struct rtnl_link_stats is kept for compatibility.

* Get link information only from specified interfaceLeo Ruan2018-08-081-7/+24
| | | | | | | | | | | libsocketcan always retrieves link information from all interfaces instead of only specified one. This commit fixes the issue by appending an interface information to dump request netlink message. See man 7 rtnetlink for detail description in section 'RTM_GETLINK'.

* Modified do_get_nl_link to potentially process multiple netlink dump replies.Andrew Beard2012-08-071-125/+130
| | | | | | | | | | | | Prior to this commit, do_get_nl_link assumed there would only be a single reply for a dump request. On my system with multiple can interfaces, this would cause only half of them to be listed in the dump reply. This change checks for NLMSG_DONE dump terminator and stops receiving messages once received.
