====================
tcp: mmap: rework zerocopy receive
syzbot reported a lockdep issue caused by tcp mmap() support.
I implemented Andy Lutomirski nice suggestions to resolve the
issue and increase scalability as well.
First patch is adding a new getsockopt() operation and changes mmap()
behavior.
Second patch changes tcp_mmap reference program.
v4: tcp mmap() support depends on CONFIG_MMU, as kbuild bot told us.
v3: change TCP_ZEROCOPY_RECEIVE to be a getsockopt() option
instead of setsockopt(), feedback from Ka-Cheon Poon
v2: Added a missing page align of zc->length in tcp_zerocopy_receive()
Properly clear zc->recv_skip_hint in case user request was completed.
====================
Signed-off-by: David S. Miller <davem@davemloft.net>
After prior kernel change, mmap() on TCP socket only reserves VMA.
We have to use getsockopt(fd, IPPROTO_TCP, TCP_ZEROCOPY_RECEIVE, ...)
to perform the transfert of pages from skbs in TCP receive queue into such VMA.
struct tcp_zerocopy_receive {
__u64 address; /* in: address of mapping */
__u32 length; /* in/out: number of bytes to map/mapped */
__u32 recv_skip_hint; /* out: amount of bytes to skip */
};
After a successful getsockopt(...TCP_ZEROCOPY_RECEIVE...), @length contains
number of bytes that were mapped, and @recv_skip_hint contains number of bytes
that should be read using conventional read()/recv()/recvmsg() system calls,
to skip a sequence of bytes that can not be mapped, because not properly page
aligned.

When adding tcp mmap() implementation, I forgot that socket lock
had to be taken before current->mm->mmap_sem. syzbot eventually caught
the bug.
Since we can not lock the socket in tcp mmap() handler we have to
split the operation in two phases.
1) mmap() on a tcp socket simply reserves VMA space, and nothing else.
This operation does not involve any TCP locking.
2) getsockopt(fd, IPPROTO_TCP, TCP_ZEROCOPY_RECEIVE, ...) implements
the transfert of pages from skbs to one VMA.
This operation only uses down_read(¤t->mm->mmap_sem) after
holding TCP lock, thus solving the lockdep issue.
This new implementation was suggested by Andy Lutomirski with great details.
Benefits are :
- Better scalability, in case multiple threads reuse VMAS
(without mmap()/munmap() calls) since mmap_sem wont be write locked.
- Better error recovery.
The previous mmap() model had to provide the expected size of the
mapping. If for some reason one part could not be mapped (partial MSS),
the whole operation had to be aborted.
With the tcp_zerocopy_receive struct, kernel can report how
many bytes were successfuly mapped, and how many bytes should
be read to skip the problematic sequence.
- No more memory allocation to hold an array of page pointers.
16 MB mappings needed 32 KB for this array, potentially using vmalloc() :/
- skbs are freed while mmap_sem has been released
Following patch makes the change in tcp_mmap tool to demonstrate
one possible use of mmap() and setsockopt(... TCP_ZEROCOPY_RECEIVE ...)
Note that memcg might require additional changes.

When we set a bond slave's master to bridge via ioctl, we only check
the IFF_BRIDGE_PORT flag. Although we will find the slave's real master
at netdev_master_upper_dev_link() later, it already does some settings
and allocates some resources. It would be better to return as early
as possible.
v1 -> v2:
use netdev_master_upper_dev_get() instead of netdev_has_any_upper_dev()
to check if we have a master, because not all upper devs are masters,
e.g. vlan device.

GLIBC seems to have non broken private copies of these headers so
this went unnoticed.
- Two microcode fixlets which address some more fallout from the
recent modifications in that area:
- Unconditionally save the microcode patch, which was only saved
when CPU_HOTPLUG was enabled causing failures in the late
loading mechanism
- Make the later loader synchronization finally work under all
circumstances. It was exiting early and causing timeout failures
due to a missing synchronization point.
- Do not use mwait_play_dead() on AMD systems to prevent excessive
power consumption as the CPU cannot go into deep power states from
there.
- Address an annoying sparse warning due to lost type qualifiers of
the vmemmap and vmalloc base address constants.
- Prevent reserving crash kernel region on Xen PV as this leads to
the wrong perception that crash kernels actually work there which
is not the case. Xen PV has its own crash mechanism handled by the
hypervisor.
- Add missing TLB cpuid values to the table to make the printout on

The comment claims that this helper will try not to loose bits, but for
64bit long it looses the high bits before hashing 64bit long into 32bit
int. Use the helper hash_long() to do the right thing for 64bit long.
For 32bit long, there is no change.
All the callers of end_name_hash() either assign the result to
qstr->hash, which is u32 or return the result as an int value (e.g.
full_name_hash()). Change the helper return type to int to conform to
its users.
[ It took me a while to apply this, because my initial reaction to it
was - incorrectly - that it could make for slower code.
After having looked more at it, I take back all my complaints about
the patch, Amir was right and I was mis-reading things or just being
stupid.
I also don't worry too much about the possible performance impact of
this on 64-bit, since most architectures that actually care about
performance end up not using this very much (the dcache code is the
most performance-critical, but the word-at-a-time case uses its own
hashing anyway).
So this ends up being mostly used for filesystems that do their own
degraded hashing (usually because they want a case-insensitive
comparison function).
A _tiny_ worry remains, in that not everybody uses DCACHE_WORD_ACCESS,
and then this potentially makes things more expensive on 64-bit
architectures with slow or lacking multipliers even for the normal
case.
That said, realistically the only such architecture I can think of is
PA-RISC. Nobody really cares about performance on that, it's more of a
"look ma, I've got warts^W an odd machine" platform.
So the patch is fine, and all my initial worries were just misplaced
from not looking at this properly. - Linus ]

U64_MAX is well defined now while the UINT64_MAX is not, so we fall
back to drivers' own definition as below:
#ifndef UINT64_MAX
#define UINT64_MAX (u64)(~((u64)0))
#endif
I believe this is in one phy driver then copied and pasted to other phy
drivers.
Replace the UINT64_MAX with U64_MAX to clean up the source code.

This implements a misc character device named "qrtr-tun" for the purpose
of allowing user space applications to implement endpoints in the qrtr

This allows more advanced (and dynamic) testing of the qrtr code as well

selftests: Add tests for mirroring to gretap
This suite tests GRE-encapsulated mirroring. The general topology that
most of the tests use is as follows, but each test defines details of
the topology based on its needs, and some tests actually use a somewhat
different topology.

+------------------------------------------------------------------+
The following axes of configuration space are tested:
- ingress and egress mirroring
- mirroring triggered by matchall and flower
- mirroring to ipgretap and ip6gretap
- remote tunnel reachable directly or through a next-hop route
- skip_sw as well as skip_hw configurations
Apart from basic tests with the above mentioned features, the following
tests are included:
- handling of changes to neighbors pertinent to routing decisions in
mirrored underlay
- handling of configuration changes at the mirrored-to tunnel (endpoint
addresses, upness)
A suite of mlxsw-specific tests will be part of a separate submission
through linux-mlxsw patch queue.

These tests set up mirroring in a situation that the configuration is
incorrect, i.e. mirrored packets, if any, are not supposed to reach
destination tunnel device. Then the configuration is rectified and
mirroring is checked to have started working.

To simplify implementation of mirror-to-gretap tests, extend lib.sh with
several new functions that might potentially be useful more
broadly (although right now the mirroring tests will be the only
client).
Also add mirror_lib.sh with code useful for mirroring tests,
mirror_gre_lib.sh with code specifically useful for mirror-to-gretap
tests, and mirror_gre_topo.sh that primes a given test with a good
baseline topology that the test can then tweak to its liking.

This series has 3 main features. The first is to add mqprio TC to
hardware queue mapping to avoid reprogramming hardware CoS queue
watermarks during run-time. The second is DIM improvements from
Andy Gospo. The third is some improvements to VF resource allocations
when supporting large numbers of VFs with more limited resources.
There are some additional minor improvements and a new function level
discard counter.

Add logic to reserve default rings at driver open time if none was
reserved during probe time. This will happen when the PF driver did
not provision minimum rings to the VF, due to more limited resources.

The current code does not reserve rings during ethtool -L when the device
is down. The rings will be reserved when the device is later opened.
Change it to reserve rings during ethtool -L when the device is down.

Testing with DIM enabled on older kernels indicated that firmware calls
were slower than expected. More detailed analysis indicated that the
default 25us delay was higher than necessary. Reducing the time spend in
usleep_range() for the first several calls would reduce the overall
latency of firmware calls on newer Intel processors.
