ipv4: Drop tos parameter from flowi4_update_output()
Callers of flowi4_update_output() never try to update ->flowi4_tos:
* ip_route_connect() updates ->flowi4_tos with its own current
value.
ipv4: Drop tos parameter from flowi4_update_output()
Callers of flowi4_update_output() never try to update ->flowi4_tos:
* ip_route_connect() updates ->flowi4_tos with its own current
value.
* ip_route_newports() has two users: tcp_v4_connect() and
dccp_v4_connect. Both initialise fl4 with ip_route_connect(), which
in turn sets ->flowi4_tos with RT_TOS(inet_sk(sk)->tos) and
->flowi4_scope based on SOCK_LOCALROUTE.
Then ip_route_newports() updates ->flowi4_tos with
RT_CONN_FLAGS(sk), which is the same as RT_TOS(inet_sk(sk)->tos),
unless SOCK_LOCALROUTE is set on the socket. In that case, the
lowest order bit is set to 1, to eventually inform
ip_route_output_key_hash() to restrict the scope to RT_SCOPE_LINK.
This is equivalent to properly setting ->flowi4_scope as
ip_route_connect() did.
* ip_vs_xmit.c initialises ->flowi4_tos with memset(0), then calls
flowi4_update_output() with tos=0.
* sctp_v4_get_dst() uses the same RT_CONN_FLAGS_TOS() when
initialising ->flowi4_tos and when calling flowi4_update_output().
In the end, ->flowi4_tos never changes. So let's just drop the tos
parameter. This will simplify the conversion of ->flowi4_tos from __u8
to dscp_t.

net: dst: Prevent false sharing vs. dst_entry:: __refcnt
dst_entry::__refcnt is highly contended in scenarios where many connections
happen from and to the same IP. The reference count is an atomic_t, so the
reference count operations have to take the cache-line exclusive.
Aside of the unavoidable reference count contention there is another
significant problem which is caused by that: False sharing.
perf top identified two affected read accesses. dst_entry::lwtstate and
rtable::rt_genid.
dst_entry:__refcnt is located at offset 64 of dst_entry, which puts it into
a seperate cacheline vs. the read mostly members located at the beginning
of the struct.
That prevents false sharing vs. the struct members in the first 64
bytes of the structure, but there is also
dst_entry::lwtstate
which is located after the reference count and in the same cache line. This
member is read after a reference count has been acquired.
struct rtable embeds a struct dst_entry at offset 0. struct dst_entry has a
size of 112 bytes, which means that the struct members of rtable which
follow the dst member share the same cache line as dst_entry::__refcnt.
Especially
rtable::rt_genid
is also read by the contexts which have a reference count acquired
already.
When dst_entry:__refcnt is incremented or decremented via an atomic
operation these read accesses stall. This was found when analysing the
memtier benchmark in 1:100 mode, which amplifies the problem extremly.
Move the rt[6i]_uncached[_list] members out of struct rtable and struct
rt6_info into struct dst_entry to provide padding and move the lwtstate
member after that so it ends up in the same cache line.
The resulting improvement depends on the micro-architecture and the number
of CPUs. It ranges from +20% to +120% with a localhost memtier/memcached
benchmark.

ipv4: Avoid using RTO_ONLINK with ip_route_connect().
Now that ip_rt_fix_tos() doesn't reset ->flowi4_scope unconditionally,
we don't have to rely on the RTO_ONLINK bit to properly set the scope
of a flowi4 structure. We can just set ->flowi4_scope explicitly and
avoid using RTO_ONLINK in ->flowi4_tos.
This patch converts callers of ip_route_connect(). Instead of setting
the tos parameter with RT_CONN_FLAGS(sk), as all callers do, we can:
1- Drop the tos parameter from ip_route_connect(): its value was
entirely based on sk, which is also passed as parameter.
2- Set ->flowi4_scope depending on the SOCK_LOCALROUTE socket option
instead of always initialising it with RT_SCOPE_UNIVERSE (let's
define ip_sock_rt_scope() for this purpose).
3- Avoid overloading ->flowi4_tos with RTO_ONLINK: since the scope is
now properly initialised, we don't need to tell ip_rt_fix_tos() to
adjust ->flowi4_scope for us. So let's define ip_sock_rt_tos(),
which is the same as RT_CONN_FLAGS() but without the RTO_ONLINK
bit overload.
Note:
In the original ip_route_connect() code, __ip_route_output_key()
might clear the RTO_ONLINK bit of fl4->flowi4_tos (because of
ip_rt_fix_tos()). Therefore flowi4_update_output() had to reuse the
original tos variable. Now that we don't set RTO_ONLINK any more,
this is not a problem and we can use fl4->flowi4_tos in
flowi4_update_output().
