ASoC: wm8978: Add OF device ID table

The driver doesn't have a struct of_device_id table but supported devices
are registered via Device Trees. This is working on the assumption that a
I2C device registered via OF will always match a legacy I2C device ID and
that the MODALIAS reported will always be of the form i2c:<device>.

But this could change in the future so the correct approach is to have an
OF device ID table if the devices are registered via OF.

Before this patch:

$ modinfo sound/soc/codecs/snd-soc-wm8978.ko | grep alias
alias:          i2c:wm8978

After this patch:

$ modinfo sound/soc/codecs/snd-soc-wm8978.ko | grep alias
alias:          i2c:wm8978

ibmveth: set correct gso_size and gso_type

This patch is based on an earlier one submitted
by Jon Maxwell with the following commit message:

"We recently encountered a bug where a few customers using ibmveth on the
same LPAR hit an issue where a TCP session hung when large receive was
enabled. Closer analysis revealed that the session was stuck because the
one side was advertising a zero window repeatedly.

We narrowed this down to the fact the ibmveth driver did not set gso_size
which is translated by TCP into the MSS later up the stack. The MSS is
used to calculate the TCP window size and as that was abnormally large,
it was calculating a zero window, even although the sockets receive buffer
was completely empty."

We rely on the Virtual I/O Server partition in a pseries
environment to provide the MSS through the TCP header checksum
field. The stipulation is that users should not disable checksum
offloading if rx packet aggregation is enabled through VIOS.

Some firmware offerings provide the MSS in the RX buffer.
This is signalled by a bit in the RX queue descriptor.

6 years agoparisc: Fix TLB related boot crash on SMP machines
Helge Deller [Thu, 8 Dec 2016 20:00:46 +0000 (21:00 +0100)]
parisc: Fix TLB related boot crash on SMP machines

At bootup we run measurements to calculate the best threshold for when we
should be using full TLB flushes instead of just flushing a specific amount of
TLB entries.  This performance test is run over the kernel text segment.

But running this TLB performance test on the kernel text segment turned out to
crash some SMP machines when the kernel text pages were mapped as huge pages.

To avoid those crashes this patch simply skips this test on some SMP machines
and calculates an optimal threshold based on the maximum number of available
TLB entries and number of online CPUs.

On a technical side, this seems to happen:
The TLB measurement code uses flush_tlb_kernel_range() to flush specific TLB
entries with a page size of 4k (pdtlb 0(sr1,addr)). On UP systems this purge
instruction seems to work without problems even if the pages were mapped as
huge pages.  But on SMP systems the TLB purge instruction is broadcasted to
other CPUs. Those CPUs then crash the machine because the page size is not as
expected.  C8000 machines with PA8800/PA8900 CPUs were not affected by this
problem, because the required cache coherency prohibits to use huge pages at
all.  Sadly I didn't found any documentation about this behaviour, so this
finding is purely based on testing with phyiscal SMP machines (A500-44 and
J5000, both were 2-way boxes).

ceph: don't set req->r_locked_dir in ceph_d_revalidate

This function sets req->r_locked_dir which is supposed to indicate to
ceph_fill_trace that the parent's i_rwsem is locked for write.
Unfortunately, there is no guarantee that the dir will be locked when
d_revalidate is called, so we really don't want ceph_fill_trace to do
any dcache manipulation from this context. Clear req->r_locked_dir since
it's clearly not safe to do that.

What we really want to know with d_revalidate is whether the dentry
still points to the same inode. ceph_fill_trace installs a pointer to
the inode in req->r_target_inode, so we can just compare that to
d_inode(dentry) to see if it's the same one after the lookup.

Also, since we aren't generally interested in the parent here, we can
switch to using a GETATTR to hint that to the MDS, which also means that
we only need to reserve one cap.

Finally, just remove the d_unhashed check. That's really outside the
purview of a filesystem's d_revalidate. If the thing became unhashed
while we're checking it, then that's up to the VFS to handle anyway.

libata-scsi: disable SCT Write Same for the moment

SCT Write Same support had been introduced with
commit 7b2030942859 ("libata: Add support for SCT Write Same")

Some problems, namely excessive userspace segfaults, had been reported at

This lead to commit 0ce1b18c42a5 ("libata: Some drives failing on
SCT Write Same") which strived to disable SCT Write Same on !ZAC devices.
Due to the way this was done and to the logic in sd_config_write_same(),
this didn't work for those devices that have
->max_ws_blocks > SD_MAX_WS10_BLOCKS: for these, ->no_write_same and
->max_write_same_sectors would still be non-zero,
but ->ws10 == ->ws16 == 0. This would cause sd_setup_write_same_cmnd() to
demultiplex REQ_OP_WRITE_SAME requests to WRITE_SAME, and these in turn
aren't supported by libata-scsi:

  EXT4-fs (dm-1): Delayed block allocation failed for inode 2625094 at
                  logical offset 2032 with max blocks 2 with error 121

121 == EREMOTEIO is what scsi_io_completion() asserts in case of
invalid opcodes.

Back to the original problem of userspace segfaults: this can be tracked
down to ata_format_sct_write_same() overwriting the input page. Sometimes,
this page is ZERO_PAGE(0) which ceases to be filled with zeros from that
point on. Since ZERO_PAGE(0) is used for userspace .bss mappings, code of
the following is doomed:

  static char *a = NULL; /* .bss */
  if (a)
    *a = 'a';

This problem is not solved by disabling SCT Write Same for !ZAC devices

It can certainly be fixed, but the final release is quite close -- so
disable SCT Write Same for all ATA devices rather than introducing some
SCT key buffer allocation schemes at this point.

Revert "default exported asm symbols to zero"

This reverts commit 8ab2ae655bfe384335c5b6b0d6041e0ddce26b00.

I loved that commit because of how it explained what the problem with
newer versions of binutils were, but the actual patch itself turns out
to not work very well.

It has two problems:

 - a zero CRC value isn't actually right.  It happens to work for the
   case where both sides of the equation fail at giving the symbol a
   crc, but there are cases where the users of the exported symbol get
   the right crc (due to seeing the C declarations), but the actual
   exporting itself does not (due to the whole weak asm symbol issue).

   So then the module load fails after all - we did have a crc for the
   symbol, but we couldn't match it with the loaded module.

 - it seems that the alpha assembler has special semantics for the
   '.set' directive, and on alpha it doesn't actually set the value of
   the specified symbol at all, it is instead used to set various
   assembly modes (eg ".set noat" and ".set noreorder").

   So using ".set" to set the symbol value would just cause build
   failures on alpha.

I'm sure we'll find some other workaround for these issues (hopefully
that involves getting rid of modversions entirely some day, but people
are also talking about just using smarter tools).  But for now we'll
just fall back on commit faaae2a58143 ("Re-enable CONFIG_MODVERSIONS in
a slightly weaker form") that just let's a missing crc through.

AAD || CT || Tag as output and vice versa for decryption. Prior to this
patch, the AF_ALG interface for AEAD ciphers requires the buffer to be
present as input for encryption. Similarly, the output buffer for
decryption required the presence of the tag buffer too. This implies
that the kernel reads / writes data buffers from/to kernel space
even though this operation is not required.

This patch changes the AF_ALG AEAD interface to be consistent with the
in-kernel AEAD cipher requirements.

Due to this handling, he changes are transparent to user space with one
exception: the return code of recv indicates the mount of output buffer.
That output buffer has a different size compared to before the patch
which implies that the return code of recv will also be different.
For example, a decryption operation uses 16 bytes AAD, 16 bytes CT and
16 bytes tag, the AF_ALG AEAD interface before showed a recv return

  "I think that is more restrictive than you intended: haven't tried, but I
  believe it rejects a PROT_READ, MAP_SHARED, O_RDONLY fd mmap, leaving no
  way to mmap /dev/dax without write permission to it."

Indeed it does restrict read-only mappings, switch to checking

tools/testing/nvdimm: unit test acpi_nfit_ctl()

A recent flurry of bug discoveries in the nfit driver's DSM marshalling
routine has highlighted the fact that we do not have unit test coverage
for this routine. Add a self-test of acpi_nfit_ctl() routine before
probing the "nfit_test.0" device. This mocks stimulus to acpi_nfit_ctl()
and if any of the tests fail "nfit_test.0" will be unavailable causing
the rest of the tests to not run / fail.

This unit test will also be a place to land reproductions of quirky BIOS
behavior discovered in the field and ensure the kernel does not regress
against implementations it has seen in practice.

acpi, nfit: fix bus vs dimm confusion in xlat_status

Given dimms and bus commands share the same command number space we need
to be careful that we are translating status in the correct context.
Otherwise we can, for example, fail an ND_CMD_GET_CONFIG_SIZE command
because max_xfer is zero. It fails because that condition erroneously
correlates with the 'cleared == 0' failure of ND_CMD_CLEAR_ERROR.

acpi, nfit, libnvdimm: fix / harden ars_status output length handling

Given ambiguities in the ACPI 6.1 definition of the "Output (Size)"
field of the ARS (Address Range Scrub) Status command, a firmware
implementation may in practice return 0, 4, or 8 to indicate that there
is no output payload to process.

The specification states "Size of Output Buffer in bytes, including this
field.". However, 'Output Buffer' is also the name of the entire
payload, and earlier in the specification it states "Max Query ARS
Status Output Buffer Size: Maximum size of buffer (including the Status
and Extended Status fields)".

Without this fix if the BIOS happens to return 0 it causes memory
corruption as evidenced by this result from the acpi_nfit_ctl() unit

ACPI DSMs can have an 'extended' status which can be non-zero to convey
additional information about the command. In the xlat_status routine,
where we translate the command statuses, we were returning an error for
a non-zero extended status, even if the primary status indicated success.

Return from each command's 'case' once we have verified both its status
and extend status are good.
