netlink: Move netlink attribute parsing support to lib

2009-03-04T06:53:30+00:00

Netlink attribute parsing may be used even if CONFIG_NET is not set. Move it from net/netlink to lib and control its inclusion based on the new config symbol CONFIG_NLATTR, which is selected by CONFIG_NET. Signed-off-by: Geert Uytterhoeven Acked-by: David S. Miller Signed-off-by: Herbert Xu

netlink: allow empty nested attributes

2008-11-28T11:05:19+00:00

validate_nla() currently doesn't allow empty nested attributes. This makes userspace code unnecessarily complicated when starting and ending the nested attribute is done by generic upper level code and the inner attributes are dumped by a module. Add a special case to accept empty nested attributes. When the nested attribute is non empty, the same checks as before are performed. Signed-off-by: Patrick McHardy Signed-off-by: David S. Miller

netlink: Improve returned error codes

2008-06-03T23:36:54+00:00

Make nlmsg_trim(), nlmsg_cancel(), genlmsg_cancel(), and nla_nest_cancel() void functions. Return -EMSGSIZE instead of -1 if the provided message buffer is not big enough. Signed-off-by: Thomas Graf Signed-off-by: David S. Miller

[NETLINK]: Add nla_append()

[NETLINK]: Introduce nested and byteorder flag to netlink attribute

2007-10-10T23:49:16+00:00

This change allows the generic attribute interface to be used within the netfilter subsystem where this flag was initially introduced. The byte-order flag is yet unused, it's intended use is to allow automatic byte order convertions for all atomic types. Signed-off-by: Thomas Graf Signed-off-by: David S. Miller

[NETLINK]: attr: add nested compat attribute type

2007-07-11T05:15:38+00:00

Add a nested compat attribute type that can be used to convert attributes that contain a structure to nested attributes in a backwards compatible way. Signed-off-by: Patrick McHardy Signed-off-by: David S. Miller

[NETLINK]: introduce NLA_BINARY type

2007-04-26T05:28:05+00:00

This patch introduces a new NLA_BINARY attribute policy type with the verification of simply checking the maximum length of the payload. It also fixes a small typo in the example. Signed-off-by: Johannes Berg Signed-off-by: Thomas Graf Signed-off-by: David S. Miller
