UIDs are printed in the proc_fs as signed int, whereas
they are unsigned int.

ping: always initialize ->sin6_scope_id and ->sin6_flowinfo

2013-06-04T23:58:42+00:00

If we don't need scope id, we should initialize it to zero.
Same for ->sin6_flowinfo.

net: ipv6: Implement /proc/net/icmp6.

2013-06-04T19:56:14+00:00

The format is based on /proc/net/icmp and /proc/net/{udp,raw}6.

Compiles and displays reasonable results with CONFIG_IPV6={n,m,y}
Couldn't figure out how to test without CONFIG_PROC_FS enabled.

net: ipv4: make the ping /proc code AF-independent

2013-06-04T19:56:14+00:00

Introduce a ping_seq_afinfo structure (similar to its UDP
equivalent) and use it to make some of the ping /proc functions
address-family independent. Rename the remaining ping /proc
functions from ping_* to ping_v4_*.

Compiles and displays reasonable results with CONFIG_IPV6={n,m,y}

net: ipv6: Add IPv6 support to the ping socket.

2013-05-26T04:07:49+00:00

This adds the ability to send ICMPv6 echo requests without a
raw socket. The equivalent ability for ICMPv4 was added in
2011.

Instead of having separate code paths for IPv4 and IPv6, make
most of the code in net/ipv4/ping.c dual-stack and only add a
few IPv6-specific bits (like the protocol definition) to a new
net/ipv6/ping.c. Hopefully this will reduce divergence and/or
duplication of bugs in the future.

Caveats:

- Setting options via ancillary data (e.g., using IPV6_PKTINFO
  to specify the outgoing interface) is not yet supported.
- There are no separate security settings for IPv4 and IPv6;
  everything is controlled by /proc/net/ipv4/ping_group_range.
- The proc interface does not yet display IPv6 ping sockets
  properly.

Tested with a patched copy of ping6 and using raw socket calls.
Compiles and works with all of CONFIG_IPV6={n,m,y}.

net: sock: make sock_tx_timestamp void

2013-04-14T19:41:49+00:00

Currently, sock_tx_timestamp() always returns 0. The comment that
describes the sock_tx_timestamp() function wrongly says that it
returns an error when an invalid argument is passed (from commit
20d4947353be, ``net: socket infrastructure for SO_TIMESTAMPING'').
Make the function void, so that we can also remove all the unneeded
if conditions that check for such a _non-existant_ error case in the
output path.

net: proc: change proc_net_remove to remove_proc_entry

2013-02-18T19:53:08+00:00

proc_net_remove is only used to remove proc entries
that under /proc/net,it's not a general function for
removing proc entries of netns. if we want to remove
some proc entries which under /proc/net/stat/, we still
need to call remove_proc_entry.

this patch use remove_proc_entry to replace proc_net_remove.
we can remove proc_net_remove after this patch.

net: proc: change proc_net_fops_create to proc_create

2013-02-18T19:53:08+00:00

Right now, some modules such as bonding use proc_create
to create proc entries under /proc/net/, and other modules
such as ipv4 use proc_net_fops_create.

It looks a little chaos.this patch changes all of
proc_net_fops_create to proc_create. we can remove
proc_net_fops_create after this patch.
