Very rarely, the KSZ9031 will appear to complete autonegotiation, but
will drop all traffic afterwards. When this happens, the idle error
count will read 0xFF after autonegotiation completes. Reset the PHY
when in that state.

Currently adding a new ipv4 address always cause the creation of the
related network route, with default metric. When a host has multiple
interfaces on the same network, multiple routes with the same metric
are created.
If the userspace wants to set specific metric on each routes, i.e.
giving better metric to ethernet links in respect to Wi-Fi ones,
the network routes must be deleted and recreated, which is error-prone.
This patch implements the support for IFA_F_NOPREFIXROUTE for ipv4
address. When an address is added with such flag set, no associated
network route is created, no network route is deleted when
said IP is gone and it's up to the user space manage such route.

overflow-arith: begin to add support for overflow builtins functions
I add a new header, linux/overflow-arith.h, as the central place to add
overflow and wrap-around checking functions. The reason I am doing so
is that it can make use of compiler supported builtin functions which
can leverage hardware.
As I need this for a fix in the ipv6 stack, which is also included in
this series, I propose to add it sooner than later over Davem's net
tree. This is also the reason why I start slowly with only the one
function I need at this time.

issues
Raw sockets with hdrincl enabled can insert ipv6 extension headers
right into the data stream. In case we need to fragment those packets,
we reparse the options header to find the place where we can insert
the fragment header. If the extension headers exceed the link's MTU we
actually cannot make progress in such a case.
Instead of ending up in broken arithmetic or rounding towards 0 and
entering an endless loop in ip6_fragment, just prevent those cases by
aborting early and signal -EMSGSIZE to user space.

The idea of the overflow-arith.h header is to collect overflow checking
functions in one central place.
If gcc compiler supports the __builtin_overflow_* builtins we use them
because they might give better performance, otherwise the code falls
back to normal overflow checking functions.
The builtin_overflow functions are supported by gcc-5 and clang. The
matter of supporting clang is to just provide a corresponding
CC_HAVE_BUILTIN_OVERFLOW, because the specific overflow checking builtins
don't differ between gcc and clang.
I just provide overflow_usub function here as I intend this to get merged
into net, more functions will definitely follow as they are needed.

If alpha is strictly reduced by alpha >> dctcp_shift_g and if alpha is less
than 1 << dctcp_shift_g, then alpha may never reach zero. For example,
given shift_g=4 and alpha=15, alpha >> dctcp_shift_g yields 0 and alpha
remains 15. The effect isn't noticeable in this case below cwnd=137, but
could gradually drive uncongested flows with leftover alpha down to
cwnd=137. A larger dctcp_shift_g would have a greater effect.
This change causes alpha=15 to drop to 0 instead of being decrementing by 1
as it would when alpha=16. However, it requires one less conditional to
implement since it doesn't have to guard against subtracting 1 from 0U. A
decay of 15 is not unreasonable since an equal or greater amount occurs at
alpha >= 240.

The error condition -EAGAIN, which is signaled by throw routes, tells
the rules framework to walk on searching for next matches. If the walk
ends and we stop walking the rules with the result of a throw route we
have to translate the error conditions to -ENETUNREACH.

When the kernel compiled with KASAN=y, GCC adds redzones for each
variable on stack. This enlarges function's stack frame and causes:
'warning: the frame size of X bytes is larger than Y bytes'
The worst case I've seen for now is following:
../net/wireless/nl80211.c: In function `nl80211_send_wiphy':
../net/wireless/nl80211.c:1731:1: warning: the frame size of 5448 bytes is larger than 2048 bytes [-Wframe-larger-than=]
That kind of warning becomes useless with KASAN=y. It doesn't
necessarily indicate that there is some problem in the code, thus we
should turn it off.
(The KASAN=y stack size in increased from 16k to 32k for this reason)

Currently a simple program below issues a sendfile(2) system call which
takes about 62 days to complete in my test KVM instance.
int fd;
off_t off = 0;
fd = open("file", O_RDWR | O_TRUNC | O_SYNC | O_CREAT, 0644);
ftruncate(fd, 2);
lseek(fd, 0, SEEK_END);
sendfile(fd, fd, &off, 0xfffffff);
Now you should not ask kernel to do a stupid stuff like copying 256MB in
2-byte chunks and call fsync(2) after each chunk but if you do, sysadmin
should have a way to stop you.
We actually do have a check for fatal_signal_pending() in
generic_perform_write() which triggers in this path however because we
always succeed in writing something before the check is done, we return
value > 0 from generic_perform_write() and thus the information about
signal gets lost.
Fix the problem by doing the signal check before writing anything. That
way generic_perform_write() returns -EINTR, the error gets propagated up
and the sendfile loop terminates early.

call_usermodehelper_exec_sync() does fork() + wait() with "unignored"
SIGCHLD. What we have missed is that this worker thread can have other
children previously forked by call_usermodehelper_exec_work() without
UMH_WAIT_PROC. If such a child exits in between it becomes a zombie
because auto-reaping only works if SIGCHLD is ignored, and nobody can
reap it (unless/until this worker thread exits too).
Change the !UMH_WAIT_PROC case to use CLONE_PARENT.
Note: this is only first step. All PF_KTHREAD tasks, even created by
kernel_thread() should have ->parent == kthreadd by default.

On sparc, deleting established SAs (e.g., by restarting ipsec)
results in unaligned access messages via xfrm_del_sa ->
km_state_notify -> xfrm_send_state_notify().
Even though struct xfrm_usersa_info is aligned on 8-byte boundaries,
netlink attributes are fundamentally only 4 byte aligned, and this
cannot be changed for nla_data() that is passed up to userspace.
As a result, the put_unaligned() macro needs to be used to
set up potentially unaligned fields such as the xfrm_stats in
copy_to_user_state()

initializer for the transport spin_lock causing an issue when
running with lockdep checking.
Testing: Verified fix on kernel with lockdep enabled.

The driver was printing a message about not being able
to assign VMDq because of a lack of MSI-X vectors.
This was because a line was missing that initialized a variable,
simply a merge error.

The code was setting up stats that were not being initialized.
This caused several counters to be displayed incorrectly, due
to indexing beyond the array of strings when printing stats.

The perf_config() infrastructure we inherited from git calls die() when
the provided config callback returns -1, meaning some key in a config
section is unexpected, that seems ok for a stdio based tool, but in
--tui we end up messing up the output, so just tell the user about the
error, wait for a keystroke and return 0, being more resilient and
proceeding with what we managed to parse.
That die() needs to die, tho :-)

I.e. we want to tell the user about errors found during, for instance,
the ui_browser initialization, so that a call to ui__warning() appears
as a window waiting for a key to be pressed.

The annotate__configs should be sorted so that it can use bsearch(3).
However commit 0c4a5bcea460 ("perf annotate: Display total number of
samples with --show-total-period") added a new config item at the end.
This resulted in the 'annotate.use_offset' config variable cannot be
found and perf terminated like below:
$ perf report

The --call-graph option is complex so we should provide better guide for
users. Also change help message to be consistent with config option
names. Now perf top will show help like below:
$ perf top --call-graph
Error: option `call-graph' requires a value
Usage: perf top [<options>]
--call-graph <record_mode[,record_size],print_type,threshold[,print_limit],order,sort_key[,branch]>
setup and enables call-graph (stack chain/backtrace):
record_mode: call graph recording mode (fp|dwarf|lbr)
record_size: if record_mode is 'dwarf', max size of stack recording (<bytes>)
default: 8192 (bytes)
print_type: call graph printing style (graph|flat|fractal|none)
threshold: minimum call graph inclusion threshold (<percent>)
print_limit: maximum number of call graph entry (<number>)
order: call graph order (caller|callee)
sort_key: call graph sort key (function|address)
branch: include last branch info to call graph (branch)
Default: fp,graph,0.5,caller,function

The caller callchain order is useful with --children option since it can
show 'overview' style output, but other commands which don't use
--children feature like 'perf script' or even 'perf report/top' without
--children are better to keep callee order.

Currently 'perf top --call-graph' option is same as 'perf record'. But
'perf top' also need to receive display options in 'perf report'. To do
that, change parse_callchain_report_opt() to allow record options too.
Now perf top can receive display options like below:
$ perf top --call-graph
Error: option `call-graph' requires a value
Usage: perf top [<options>]
--call-graph
<mode[,dump_size],output_type,min_percent[,print_limit],call_order[,branch]>
setup and enables call-graph (stack chain/backtrace)
recording: fp dwarf lbr, output_type (graph, flat,
fractal, or none), min percent threshold, optional
print limit, callchain order, key (function or
address), add branches
$ perf top --call-graph callee,graph,fp

Commits such as 65dd297ac25565 ("xfs: %pF is only for function
pointers") caused a regression because pretty_print() didn't support
%ps/%pS. The current %pf/%pF implementation in pretty_print() is what
%ps/%pS is supposed to do, so use the same code for %ps/%pS.
Addressing the incorrect %pf/%pF implementation is beyond the scope of
this patch.
