sprintf does not know the PAGE_SIZE maximum of the temporary buffer
used for outputting sysfs content and it's possible to overrun the
PAGE_SIZE buffer length.

Use a generic sysfs_emit function that knows the size of the
temporary buffer and ensures that no overrun is done for offset
attribute in
loop_attr_[offset|sizelimit|autoclear|partscan|dio]_show() callbacks.

These ioctls are equivalent to fcntl(fd, F_SETFD, flags), which SELinux
always allows too.  Furthermore, a failed FIOCLEX could result in a file
descriptor being leaked to a process that should not have access to it.

As this patch removes access controls, a policy capability needs to be
enabled in policy to always allow these ioctls.

The usual LSM hook "bail on fail" scheme doesn't work for cases where
a security module may return an error code indicating that it does not
recognize an input.  In this particular case Smack sees a mount option
that it recognizes, and returns 0. A call to a BPF hook follows, which
returns -ENOPARAM, which confuses the caller because Smack has processed
its data.

The SELinux hook incorrectly returns 1 on success. There was a time
when this was correct, however the current expectation is that it
return 0 on success. This is repaired.

[ Upstream commit d888c83f ]

Jason Donenfeld reports that my commit 1c24a186 ("fs: fd tables have
to be multiples of BITS_PER_LONG") doesn't work, and the reason is an
embarrassing brown-paper-bag bug.

Yes, we want to align the number of fds to BITS_PER_LONG, and yes, the
reason they might not be aligned is because the incoming 'max_fd'
argument might not be aligned.

But aligining the argument - while simple - will cause a "infinitely
big" maxfd (eg NR_OPEN_MAX) to just overflow to zero.  Which most
definitely isn't what we want either.

The obvious fix was always just to do the alignment last, but I had
moved it earlier just to make the patch smaller and the code look
simpler.  Duh.  It certainly made _me_ look simple.

--------------------------------

[ Upstream commit 1c24a186 ]

This has always been the rule: fdtables have several bitmaps in them,
and as a result they have to be sized properly for bitmaps.  We walk
those bitmaps in chunks of 'unsigned long' in serveral cases, but even
when we don't, we use the regular kernel bitops that are defined to work
on arrays of 'unsigned long', not on some byte array.

Now, the distinction between arrays of bytes and 'unsigned long'
normally only really ends up being noticeable on big-endian systems, but
Fedor Pchelkin and Alexey Khoroshilov reported that copy_fd_bitmaps()
could be called with an argument that wasn't even a multiple of
BITS_PER_BYTE.  And then it fails to do the proper copy even on
little-endian machines.

The bug wasn't in copy_fd_bitmap(), but in sane_fdtable_size(), which
didn't actually sanitize the fdtable size sufficiently, and never made
sure it had the proper BITS_PER_LONG alignment.

That's partly because the alignment historically came not from having to
explicitly align things, but simply from previous fdtable sizes, and
from count_open_files(), which counts the file descriptors by walking
them one 'unsigned long' word at a time and thus naturally ends up doing
sizing in the proper 'chunks of unsigned long'.

But with the introduction of close_range(), we now have an external
source of "this is how many files we want to have", and so
sane_fdtable_size() needs to do a better job.

This also adds that explicit alignment to alloc_fdtable(), although
there it is mainly just for documentation at a source code level.  The
arithmetic we do there to pick a reasonable fdtable size already aligns
the result sufficiently.

In fact,clang notices that the added ALIGN() in that function doesn't
actually do anything, and does not generate any extra code for it.

It turns out that gcc ends up confusing itself by combining a previous
constant-sized shift operation with the variable-sized shift operations
in roundup_pow_of_two().  And probably due to that doesn't notice that
the ALIGN() is a no-op.  But that's a (tiny) gcc misfeature that doesn't
matter.  Having the explicit alignment makes sense, and would actually
matter on a 128-bit architecture if we ever go there.

This also adds big comments above both functions about how fdtable sizes
have to have that BITS_PER_LONG alignment.

In nfs4_callback_devicenotify(), if we don't find a matching entry for
the deviceid, we're left with a pointer to 'struct nfs_server' that
actually points to the list of super blocks associated with our struct
nfs_client.
Furthermore, even if we have a valid pointer, nothing pins the super
block, and so the struct nfs_server could end up getting freed while
we're using it.

Since all we want is a pointer to the struct pnfs_layoutdriver_type,
let's skip all the iteration over super blocks, and just use APIs to
find the layout driver directly.

[ Upstream commit b50d3b46 ]

The purpose of the last test case is to test VXLAN encapsulation and
decapsulation when the underlay lookup takes place in a non-default VRF.
This is achieved by enslaving the physical device of the tunnel to a
VRF.

The binding of the VXLAN UDP socket to the VRF happens when the VXLAN
device itself is opened, not when its physical device is opened. This
was also mentioned in the cited commit ("tests that moving the underlay
from a VRF to another works when down/up the VXLAN interface"), but the
test did something else.

Fix it by reopening the VXLAN device instead of its physical device.

Before:

 # ./test_vxlan_under_vrf.sh
 Checking HV connectivity                                           [ OK ]
 Check VM connectivity through VXLAN (underlay in the default VRF)  [ OK ]
 Check VM connectivity through VXLAN (underlay in a VRF)            [FAIL]

After:

 # ./test_vxlan_under_vrf.sh
 Checking HV connectivity                                           [ OK ]

[ Upstream commit bf8bfc43 ]

A Broadcom AC201 PHY (same entry as 5241) would be flagged by the
Broadcom UniMAC MDIO controller as not completing the turn around
properly since the PHY expects 65 MDC clock cycles to complete a write
cycle, and the MDIO controller was only sending 64 MDC clock cycles as
determined by looking at a scope shot.

This would make the subsequent read fail with the UniMAC MDIO controller
command field having MDIO_READ_FAIL set and we would abort the
brcm_fet_config_init() function and thus not probe the PHY at all.

After issuing a software reset, wait for at least 1ms which is well
above the 1us reset delay advertised by the datasheet and issue a dummy
read to let the PHY turn around the line properly. This read
specifically ignores -EIO which would be returned by MDIO controllers
checking for the line being turned around.

If we have a genuine reaad failure, the next read of the interrupt
status register would pick it up anyway.

--------------------------------

[ Upstream commit de2ae403 ]

is_xen_pmu() is taking the cpu number as parameter, but it is not using
it. Instead it just tests whether the Xen PMU initialization on the
current cpu did succeed. As this test is done by checking a percpu
pointer, preemption needs to be disabled in order to avoid switching
the cpu while doing the test. While resuming from suspend() this seems
not to be the case:

Fix that by replacing is_xen_pmu() by a simple boolean variable which

Modify xen_pmu_init() to return early in case it is being called for a
cpu other than cpu 0 and the boolean variable not being set.

[ Upstream commit 5f7e2af0 ]

When registering a clock that doesn't have a recalc_rate implementation,
and doesn't have its parent registered yet, we initialize the clk_core
rate and 'req_rate' fields to 0.

The rate field is later updated when the parent is registered in
clk_core_reparent_orphans_nolock() using __clk_recalc_rates(), but the
'req_rate' field is never updated.

This leads to an issue in clk_set_rate_range() and clk_put(), since
those functions will call clk_set_rate() with the content of 'req_rate'
to provide drivers with the opportunity to change the rate based on the
new boundaries. In this case, we would call clk_set_rate() with a rate
of 0, effectively enforcing the minimum allowed for this clock whenever
we would call one of those two functions, even though the actual rate
might be within range.

Let's fix this by setting 'req_rate' in
clk_core_reparent_orphans_nolock() with the rate field content just
updated by the call to __clk_recalc_rates().

[ Upstream commit c1cb8142 ]

Currently kdb_putarea_size() uses copy_from_kernel_nofault() to write *to*
arbitrary kernel memory. This is obviously wrong and means the memory
modify ('mm') command is a serious risk to debugger stability: if we poke
to a bad address we'll double-fault and lose our debug session.

Fix this the (very) obvious way.

Note that there are two Fixes: tags because the API was renamed and this
patch will only trivially backport as far as the rename (and this is
probably enough). Nevertheless Christoph's rename did not introduce this
problem so I wanted to record that!

[ Upstream commit f58c252e ]

When 8250 UART is using DMA, x_char (XON/XOFF) is never sent
to the wire. After this change, x_char is injected correctly.

Create uart_xchar_out() helper for sending the x_char out and
accounting related to it. It seems that almost every driver
does these same steps with x_char. Except for 8250, however,
almost all currently lack .serial_out so they cannot immediately
take advantage of this new helper.

The downside of this patch is that it might reintroduce
the problems some devices faced with mixed DMA/non-DMA transfer
which caused revert f967fc8f (Revert "serial: 8250_dma:
don't bother DMA with small transfers"). However, the impact
should be limited to cases with XON/XOFF (that didn't work
with DMA capable devices to begin with so this problem is not
very likely to cause a major issue, if any at all).

__setup() handlers should return 1 to indicate that the boot option
has been handled or 0 to indicate that it was not handled.
Add a pr_warn() message if the option value is invalid and then
always return 1.

[ Upstream commit 54fe55fb ]

mtk_pconf_group_get(), used to read back pingroup pin config state,
simply returns a set of configs saved from a previous invocation of
mtk_pconf_group_set(). This is an unfiltered, unvalidated set passed
in from the pinconf core, which does not match the current hardware
state.

Since the driver library is designed to have one pin per group, pass
through mtk_pconf_group_get() to mtk_pinconf_get(), to read back the
current pin config state of the only pin in the group.

Also drop the assignment of pin config state to the group.

For mtk_pinconf_get(), the "argument" argument is typically returned by
pinconf_to_config_argument(), which holds the value for a given pinconf

which describes the type of the pinconf parameter itself.

Change the type to u32, which matches the return type of
pinconf_to_config_argument().
