2016-06-10net: diag: add missing declarationsBen Dooks1-0/+6
The functions inet_diag_msg_common_fill and inet_diag_msg_attrs_fill seem to have been missed from the include/linux/inet_diag.h header file. Add them to fix the following warnings: net/ipv4/inet_diag.c:69:6: warning: symbol 'inet_diag_msg_common_fill' was not declared. Should it be static? net/ipv4/inet_diag.c:108:5: warning: symbol 'inet_diag_msg_attrs_fill' was not declared. Should it be static?

2015-12-15net: diag: Support SOCK_DESTROY for inet sockets.Lorenzo Colitti1-0/+4
This passes the SOCK_DESTROY operation to the underlying protocol diag handler, or returns -EOPNOTSUPP if that handler does not define a destroy operation. Most of this patch is just renaming functions. This is not strictly necessary, but it would be fairly counterintuitive to have the code to destroy inet sockets be in a function whose name starts with inet_diag_get.

2015-12-15net: diag: split inet_diag_dump_one_icsk into twoLorenzo Colitti1-0/+5
Currently, inet_diag_dump_one_icsk finds a socket and then dumps its information to userspace. Split it into a part that finds the socket and a part that dumps the information.

2015-06-15sock_diag: specify info_size per inet protocolCraig Gallek1-0/+1
Previously, there was no clear distinction between the inet protocols that used struct tcp_info to report information and those that didn't. This change adds a specific size attribute to the inet_diag_handler struct which defines these interfaces. This will make dispatching sock_diag get_info requests identical for all inet protocols in a following patch.

2011-12-16sock_diag: Generalize requests cookies managementsPavel Emelyanov1-1/+0

2011-12-09inet_diag: Generalize inet_diag dump and get_exact callsPavel Emelyanov1-1/+17
Introduce two callbacks in inet_diag_handler -- one for dumping all sockets (with filters) and the other one for dumping a single sk. Replace direct calls to icsk handlers with indirect calls to callbacks provided by handlers. Make existing TCP and DCCP handlers use provided helpers for icsk-s. The UDP diag module will provide its own. Signed-off-by: Pavel Emelyanov <xemul@parallels.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2011-12-09inet_diag: Introduce the inet socket dumping routinePavel Emelyanov1-0/+7
The existing inet_csk_diag_fill dumps the inet connection sock info into the netlink inet_diag_message. Prepare this routine to be able to dump only the inet_sock part of a socket if the icsk part is missing. This will be used by UDP diag module when dumping UDP sockets.

2011-12-09inet_diag: Export inet diag cookie checking routinePavel Emelyanov1-0/+2

2011-12-09inet_diag: Remove indirect sizeof from inet diag handlersPavel Emelyanov1-1/+0
There's an info_size value stored on inet_diag_handler, but for existing code this value is effectively constant, so just use sizeof(struct tcp_info) where required. Signed-off-by: Pavel Emelyanov <xemul@parallels.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2011-11-14net-netlink: Add a new attribute to expose TCLASS values via netlinkMaciej Żenczykowski1-1/+2
commit 3ceca749668a52bd795585e0f71c6f0b04814f7b added a TOS attribute. Unfortunately TOS and TCLASS are both present in a dual-stack v6 socket, furthermore they can have different values. As such one cannot in a sane way expose both through a single attribute.

2011-10-12net-netlink: Add a new attribute to expose TOS values via netlinkMurali Raja1-1/+2
This patch exposes the tos value for the TCP sockets when the TOS flag is requested in the ext_flags for the inet_diag request. This would mainly be used to expose TOS values for both for TCP and UDP sockets. Currently it is supported for TCP. When netlink support for UDP would be added the support to expose the TOS values would alse be done. For IPV4 tos value is exposed and for IPV6 tclass value is exposed.
