lsm,selinux: pass flowi_common instead of flowi to the LSM hooks

2020-11-23T23:36:21+00:00

As pointed out by Herbert in a recent related patch, the LSM hooks do
not have the necessary address family information to use the flowi
struct safely.  As none of the LSMs currently use any of the protocol
specific flowi information, replace the flowi pointers with pointers
to the address family independent flowi_common struct.

ipv6/ping: set skb->mark on icmpv6 sockets

2020-07-03T21:36:04+00:00

IPv6 ping sockets route based on fwmark, but do not yet set skb->mark.
Add this. IPv4 ping sockets also do both.

ipv6: Fix the link time qualifier of 'ping_v6_proc_exit_net()'

2019-09-12T10:20:33+00:00

The '.exit' functions from 'pernet_operations' structure should be marked
as __net_exit, not __net_init.

ipv6: fold sockcm_cookie into ipcm6_cookie

2018-07-07T01:58:49+00:00

ipcm_cookie includes sockcm_cookie. Do the same for ipcm6_cookie.

This reduces the number of arguments that need to be passed around,
applies ipcm6_init to all cookie fields at once and reduces code
differentiation between ipv4 and ipv6.

ipv6: ipcm6_cookie initializer

2018-07-07T01:58:49+00:00

Initialize the cookie in one location to reduce code duplication and
avoid bugs from inconsistent initialization, such as that fixed in
commit 9887cba19978 ("ip: limit use of gso_size to udp").

proc: introduce proc_create_net{,_data}

2018-05-16T05:24:30+00:00

Variants of proc_create{,_data} that directly take a struct seq_operations
and deal with network namespaces in ->open and ->release.  All callers of
proc_create + seq_open_net converted over, and seq_{open,release}_net are
removed entirely.

ipv6: allow to cache dst for a connected sk in ip6_sk_dst_lookup_flow()

2018-04-04T15:31:57+00:00

Add 'connected' parameter to ip6_sk_dst_lookup_flow() and update
the cache only if ip6_sk_dst_check() returns NULL and a socket
is connected.

The function is used as before, the new behavior for UDP sockets
in udpv6_sendmsg() will be enabled in the next patch.

net/ipv6: Convert icmpv6_push_pending_frames to void

2017-10-06T16:52:31+00:00

commit cc71b7b07119 ("net/ipv6: remove unused err variable on
icmpv6_push_pending_frames") exposed icmpv6_push_pending_frames
return value not being used.

Remove now unnecessary int err declarations and uses.

o Remove unnecessary goto and out: labels
o Realign arguments
