* ipvlan: fix signature of rtnl_link_ipvlan_get_mode() to signal errorThomas Haller2015-06-261-6/+7
| | | | | | | | http://lists.infradead.org/pipermail/libnl/2015-June/001902.html Fixes: 7de5be85bf9aa3eb9f022e4813226135e89adec2 Signed-off-by: Thomas Haller <thaller@redhat.com>
* neigh: accept "norarp" in rtnl_neigh_state2str()Thomas Haller2015-06-261-1/+6
| | | | | | | | Commit 6a9335f101e22cd5eaba4dfcf0a44e2c3097b4ab fixed a typo in the string-to-flags conversion. At least for rtnl_neigh_str2state() we want to continue to parse "norarp" for backward compatiblity. Signed-off-by: Thomas Haller <thaller@redhat.com>

* lib/doc: clearify return value of send_simple() functionsThomas Haller2015-05-121-3/+3
| | | | | | | | | | | | | | | | | | The return value of the *nl_send_simple() functions is inconsistent and not according to the documentation. nl_send_simple() is document to return the number of bytes sent. Other *nl_send_simple() functions are documented to return 0 on success -- for the most part. See also commit b70174668b9867de573cf51471bc98bfe7fd2bc3 which changed behavior of nl_rtgen_request() to be according to documenation. Don't change behavior again, only adjust the documentation. http://lists.infradead.org/pipermail/libnl/2015-May/001872.html Reported-by: Xiao Jia <stfairy@gmail.com> Signed-off-by: Thomas Haller <thaller@redhat.com>

| | | | | | | | | | | The tc_kind member of struct rtnl_tc (and all types which can be converted to it) is defined as an array and can thus never be NULL. http://lists.infradead.org/pipermail/libnl/2015-April/001869.html Signed-off-by: Tobias Klauser <tklauser@distanz.ch> Signed-off-by: Thomas Haller <thaller@redhat.com>

* link: fix memory leaks due to repeated calls to .io_alloc()Thomas Haller2014-10-129-39/+77
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | All the io_alloc() implementation unconditionally allocated new memory, thus leaking memory if called more then once.

| | | | | | | | | | | [thaller@redhat.com: I modified the condition "if (data && len)" in the original patch to just check "len > 0".
