dcbnl: fix various netlink info leaks

2013-03-20T19:58:54Z

[ Upstream commit 29cd8ae0e1a39e239a3a7b67da1986add1199fc0 ] The dcb netlink interface leaks stack memory in various places: * perm_addr[] buffer is only filled at max with 12 of the 32 bytes but copied completely, * no in-kernel driver fills all fields of an IEEE 802.1Qaz subcommand, so we're leaking up to 58 bytes for ieee_ets structs, up to 136 bytes for ieee_pfc structs, etc., * the same is true for CEE -- no in-kernel driver fills the whole struct, Prevent all of the above stack info leaks by properly initializing the buffers/structures involved.

rtnetlink: Compute and store minimum ifinfo dump size

2013-01-17T16:43:58Z

commit c7ac8679bec9397afe8918f788cbcef88c38da54 upstream. The message size allocated for rtnl ifinfo dumps was limited to a single page. This is not enough for additional interface info available with devices that support SR-IOV and caused a bug in which VF info would not be displayed if more than approximately 40 VFs were created per interface. Implement a new function pointer for the rtnl_register service that will calculate the amount of data required for the ifinfo dump and allocate enough data to satisfy the request.

dcbnl: add support for retrieving peer configuration - cee

2011-03-03T05:58:55Z

This patch adds the support for retrieving the remote or peer DCBX configuration via dcbnl for embedded DCBX stacks supporting the CEE DCBX standard. Signed-off-by: Shmulik Ravid Signed-off-by: David S. Miller

dcbnl: add support for retrieving peer configuration - ieee

2011-03-03T05:58:54Z

These 2 patches add the support for retrieving the remote or peer DCBX configuration via dcbnl for embedded DCBX stacks. The peer configuration is part of the DCBX MIB and is useful for debugging and diagnostics of the overall DCB configuration. The first patch add this support for IEEE 802.1Qaz standard the second patch add the same support for the older CEE standard. Diff for v2 - the peer-app-info is CEE specific.

net: dcbnl: check correct ops in dcbnl_ieee_set()

2011-03-02T23:04:33Z

The incorrect ops routine was being tested for in DCB_ATTR_IEEE_PFC attributes. This patch corrects it. Currently, every driver implementing ieee_setets also implements ieee_setpfc so this bug is not actualized yet. Signed-off-by: John Fastabend Signed-off-by: David S. Miller

Don't potentially dereference NULL in net/dcb/dcbnl.c:dcbnl_getapp()

2011-02-13T19:21:14Z

nla_nest_start() may return NULL. If it does then we'll blow up in nla_nest_end() when we dereference the pointer. Signed-off-by: Jesper Juhl Signed-off-by: David S. Miller

net: dcb: application priority is per net_device

2011-02-13T19:02:39Z

The app_data priority may not be the same for all net devices. In order for stacks with application notifiers to identify the specific net device dcb_app_type should be passed in the ptr. This allows handlers to use dev_get_by_name() to pin priority to net devices. Signed-off-by: John Fastabend Signed-off-by: David S. Miller

dcbnl: make get_app handling symmetric for IEEE and CEE DCBx

2011-01-24T23:19:55Z

The IEEE get/set app handlers use generic routines and do not require the net_device to implement the dcbnl_ops routines. This patch makes it symmetric so user space and drivers do not have to handle the CEE version and IEEE DCBx versions differently. Signed-off-by: John Fastabend Signed-off-by: David S. Miller
