net: assorted y2038 changes
This is a set of changes for network drivers and core code to
get rid of the use of time_t and derived data structures.
I have a longer set of patches that enables me to build kernels
with the time_t definition removed completely as a help to find
y2038 overflow issues. This is the subset for networking that
contains all code that has a reasonable way of fixing at the
moment and that is either commonly used (in one of the defconfigs)
or that blocks building a whole subsystem.
Most of the patches in this series should be noncontroversial,
but the last two that I marked [RFC] are a bit tricky and
need input from people that are more familiar with the code than
I am. All 12 patches are independent of one another and can
be applied in any order, so feel free to pick all that look
good.
Patches that are not included here are:
- disabling less common device drivers that I don't have a fix
for yet, this includes

We'll get there eventually, or we an add a dependency to ensure
they are not built on 32-bit kernels that need to survive
beyond 2038. Most of these should be really easy to fix.
- recvmmsg/sendmmsg system calls: patches have been sent out
as part of the syscall series, need a little more work and
review
- SIOCGSTAMP/SIOCGSTAMPNS/ ioctl calls: tricky, need to discuss
with some folks at kernel summit
- SO_RCVTIMEO/SO_SNDTIMEO/SO_TIMESTAMP/SO_TIMESTAMPNS socket
opt: similar and related to the ioctl
- mmapped packet socket: need to create v4 of the API, nontrivial
- pktgen: sends 32-bit timestamps over network, need to find out
if using unsigned stamps is good enough
- af_rxpc: similar to pktgen, uses 32-bit times for deadlines
- ppp ioctl: patch is being worked on, nontrivial but doable

We want to avoid using time_t in the kernel because of the y2038
overflow problem. The use in sctp is not for storing seconds at
all, but instead uses microseconds and is passed as 32-bit
on all machines.
This patch changes the type to u32, which better fits the use.

The ipv6 mip6 implementation is one of only a few users of the
skb_get_timestamp() function in the kernel, which is both unsafe
on 32-bit architectures because of the 2038 overflow, and slightly
less efficient than the skb_get_ktime() based approach.
This converts the function call and the mip6_report_rate_limiter
structure that stores the time stamp, eliminating all uses of
timeval in the ipv6 code.

The __build_packet_message function fills a nfulnl_msg_packet_timestamp
structure that uses 64-bit seconds and is therefore y2038 safe, but
it uses an intermediate 'struct timespec' which is not.
This trivially changes the code to use 'struct timespec64' instead,
to correct the result on 32-bit architectures.

The zatm_t_hist structure is not used anywhere in the kernel, but is
exported to user space. As we are trying to eliminate uses of time_t
in the kernel for y2038 compatibility, the current definition triggers
checking tools because it contains 'struct timeval'.
As pointed out by Chas Williams, the only user of this structure was
the ZATM_GETHIST ioctl command that has been removed a long time ago,
and we can remove the structure as well without breaking any user
space.

The mac80211 code uses ktime_get_ts to measure the connected time.
As this uses monotonic time, it is y2038 safe on 32-bit systems,
but we still want to deprecate the use of 'timespec' because most
other users are broken.
This changes the code to use ktime_get_seconds() instead, which
avoids the timespec structure and is slightly more efficient.

mwifiex_get_random_ba_threshold() uses a complex homegrown implementation
to generate a pseudo-random number from the current time as returned
from do_gettimeofday().
This currently requires two 32-bit divisions plus a couple of other
computations that are eventually discarded as only eight bits of
the microsecond portion are used at all.
We could replace this with a call to get_random_bytes(), but that
might drain the entropy pool too fast if this is called for each
packet.
Instead, this patch converts it to use ktime_get_ns(), which is a
bit faster than do_gettimeofday(), and then uses a similar algorithm
as before, but in a way that takes both the nanosecond and second
portion into account for slightly-more-but-still-not-very-random
pseudorandom number.

The mwifiex_11n_aggregate_pkt() function creates a ktime_t from

This solves both problems by using the appropriate ktime_get_real()

The fec_ptp_enable_pps uses an open-coded implementation of ns_to_timespec,
which will be removed eventually as it is not y2038-safe on 32-bit
architectures. Two more instances of the same code in this file were
already converted to use the safe ns_to_timespec64 in commit 6630514fce
("ptp: fec: use helpers for converting ns to timespec"), this changes
the last one as well.
The seconds portion here is actually unused and we could just remove the
timespec variable, but using ns_to_timespec64 can still be better as the
implementation can be hand-optimized in the future.

====================
ipv4: Hash-based multipath routing
When the routing cache was removed in 3.6, the IPv4 multipath algorithm changed
from more or less being destination-based into being quasi-random per-packet
scheduling. This increases the risk of out-of-order packets and makes it
impossible to use multipath together with anycast services.
This patch series replaces the old implementation with flow-based load
balancing based on a hash over the source and destination addresses.
Distribution of the hash is done with thresholds as described in RFC 2992.
This reduces the disruption when a path is added/remove when having more than
two paths.
To futher the chance of successful usage in conjuction with anycast, ICMP
error packets are hashed over the inner IP addresses. This ensures that PMTU
will work together with anycast or load-balancers such as IPVS.
Port numbers are not considered since fragments could cause problems with
anycast and IPVS. Relying on the DF-flag for TCP packets is also insufficient,
since ICMP inspection effectively extracts information from the opposite
flow which might have a different state of the DF-flag. This is also why the
RSS hash is not used. These are typically based on the NDIS RSS spec which
mandates TCP support.
Measurements of the additional overhead of a two-path multipath
(p_mkroute_input excl. __mkroute_input) on a Xeon X3550 (4 cores, 2.66GHz):
Original per-packet: ~394 cycles/packet
L3 hash: ~76 cycles/packet
Changes in v5:
- Fixed compilation error
Changes in v4:
- Functions take hash directly instead of func ptr
- Added inline hash function
- Added dummy macros to minimize ifdefs
- Use upper 31 bits of hash instead of lower
Changes in v3:
- Multipath algorithm is no longer configurable (always L3)
- Added random seed to hash
- Moved ICMP inspection to isolated function
- Ignore source quench packets (deprecated as per RFC 6633)
Changes in v2:
- Replaced 8-bit xor hash with 31-bit jenkins hash
- Don't scale weights (since 31-bit)
- Avoided unnecesary renaming of variables
- Rely on DF-bit instead of fragment offset when checking for fragmentation
- upper_bound is now inclusive to avoid overflow
- Use a callback to postpone extracting flow information until necessary
- Skipped ICMP inspection entirely with L4 hashing
- Handle newly added sysctl ignore_routes_with_linkdown

There are multiple races that need fixes :
1) skb_get() + queue skb + kfree_skb() is racy
An accept() can be done on another cpu, data consumed immediately.
tcp_recvmsg() uses __kfree_skb() as it is assumed all skb found in
socket receive queue are private.
Then the kfree_skb() in tcp_rcv_state_process() uses an already freed skb
2) tcp_reqsk_record_syn() needs to be done before tcp_try_fastopen()
for the same reasons.
3) We want to send the SYNACK before queueing child into accept queue,
otherwise we might reintroduce the ooo issue fixed in

Under certain circumstances, we can get an extra VF_RESOURCES message
from the PF driver at runtime. When this happens, we need to parse it
because our VSI may have changed out from underneath us, and that will
affect our relationship with the PF driver.
However, parsing the resources message also blows away our current MAC
address in the hardware struct, usually with all zeros. When this
happens, the next time the interface is opened, it will have no MAC
address and will a) not work and b) complain.
Fix this issue by restoring the current MAC address from the netdev
struct after we parse the resource message.
