2018-08-03l2tp: ignore L2TP_ATTR_MTUGuillaume Nault1-1/+1
This attribute's handling is broken. It can only be used when creating Ethernet pseudo-wires, in which case its value can be used as the initial MTU for the l2tpeth device. However, when handling update requests, L2TP_ATTR_MTU only modifies session->mtu. This value is never propagated to the l2tpeth device. Dump requests also return the value of session->mtu, which is not synchronised anymore with the device MTU. The same problem occurs if the device MTU is properly updated using the generic IFLA_MTU attribute. In this case, session->mtu is not updated, and L2TP_ATTR_MTU will report an invalid value again when dumping the session. It does not seem worthwhile to complexify l2tp_eth.c to synchronise session->mtu with the device MTU. Even the ip-l2tp manpage advises to use 'ip link' to initialise the MTU of l2tpeth devices (iproute2 does not handle L2TP_ATTR_MTU at all anyway). So let's just ignore it entirely.

2018-07-27l2tp: drop ->mru from struct l2tp_sessionGuillaume Nault1-1/+1
This field is not used. Treat PPPIOC*MRU the same way as PPPIOC*FLAGS: "get" requests return 0, while "set" requests vadidate the user supplied pointer but discard its value. Signed-off-by: Guillaume Nault <[email protected]> Signed-off-by: David S. Miller <[email protected]>

2018-01-05l2tp: revert "l2tp: add peer_offset parameter"James Chapman1-1/+0
Revert commit f15bc54eeecd ("l2tp: add peer_offset parameter"). This is removed because it is adding another configurable offset and configurable offsets are being removed. Signed-off-by: James Chapman <[email protected]> Signed-off-by: David S. Miller <[email protected]>
2017-12-27l2tp: add peer_offset parameterLorenzo Bianconi1-0/+1
Introduce peer_offset parameter in order to add the capability to specify two different values for payload offset on tx/rx side. If just offset is provided by userspace use it for rx side as well in order to maintain compatibility with older l2tp versions Signed-off-by: Lorenzo Bianconi <[email protected]> Signed-off-by: David S.

2017-11-02License cleanup: add SPDX license identifier to uapi header files with no ↵Greg Kroah-Hartman1-0/+1
license Many user space API headers are missing licensing information, which makes it hard for compliance tools to determine the correct license. By default are files without license information under the default license of the kernel, which is GPLV2. Marking them GPLV2 would exclude them from being included in non GPLV2 code, which is obviously not intended. The user space API headers fall under the syscall exception which is in the kernels COPYING file: NOTE! This copyright does *not* cover user programs that use kernel services by normal system calls - this is merely considered normal use of the kernel, and does *not* fall under the heading of "derived work". otherwise syscall usage would not be possible. Update the files which contain no license information with an SPDX license identifier. The chosen identifier is 'GPL-2.0 WITH Linux-syscall-note' which is the officially assigned identifier for the Linux syscall exception. SPDX license identifiers are a legally binding shorthand, which can be used instead of the full boiler plate text. This patch is based on work done by Thomas Gleixner and Kate Stewart and Philippe Ombredanne. See the previous patch in this series for the methodology of how this patch was researched.

2017-02-14uapi: fix linux/if_pppol2tp.h userspace compilation errorsDmitry V. Levin1-4/+3
Because of <linux/libc-compat.h> interface limitations, <netinet/in.h> provided by libc cannot be included after <linux/in.h>, therefore any header that includes <netinet/in.h> cannot be included after <linux/in.h>. Change uapi/linux/l2tp.h, the last uapi header that includes <netinet/in.h>, to include <linux/in.h> and <linux/in6.h> instead of <netinet/in.h> and use __SOCK_SIZE__ instead of sizeof(struct sockaddr) the same way as uapi/linux/in.h does, to fix linux/if_pppol2tp.h userspace compilation errors like this: In file included from /usr/include/linux/l2tp.h:12:0, from /usr/include/linux/if_pppol2tp.h:21, /usr/include/netinet/in.h:31:8: error: redefinition of 'struct in_addr' Fixes: 47c3e7783be4 ("net: l2tp: deprecate PPPOL2TP_MSG_* in favour of L2TP_MSG_*") Signed-off-by: Dmitry V.

The attributes L2TP_ATTR_UDP_ZERO_CSUM6_RX and L2TP_ATTR_UDP_ZERO_CSUM6_TX are used as flags, but is defined as a u8 in a comment. This patch redocuments them as flags. Adding nla_policy entries would break API, so not doing that. CC: Tom Herbert <[email protected]> Signed-off-by: Asbjoern Sloth Toennesen <[email protected]> Signed-off-by: David S.

Previously l2tp module did not provide any means for the user space to get notified when tunnels/sessions are added/modified/deleted. This change contains the following - create a multicast group for the listeners to register. - notify the registered listeners when the tunnels/sessions are created/modified/deleted.
