Move PARIDE protocol modules out of drivers/block into
drivers/ata/pata_parport and update the CONFIG_ symbol names to
PATA_PARPORT.
[Damien]
The pata_parport driver file itsef is also moved together with the
protocol modules in drivers/ata/pata_parport.

The pata_parport is a libata-based replacement of the old PARIDE
subsystem - driver for parallel port IDE devices.
It uses the original paride low-level protocol drivers but does not
need the high-level drivers (pd, pcd, pf, pt, pg). The IDE devices
behind parallel port adapters are handled by the ATA layer.
This will allow paride and its high-level drivers to be removed.
Unfortunately, libata drivers cannot sleep so pata_parport claims
parport before activating the ata host and keeps it claimed (and
protocol connected) until the ata host is removed. This means that
no devices can be chained (neither other pata_parport devices nor
a printer).
paride and pata_parport are mutually exclusive because the compiled
protocol drivers are incompatible.
Tested with:
- Imation SuperDisk LS-120 and HP C4381A (EPAT)
- Freecom Parallel CD (FRPW)
- Toshiba Mobile CD-RW 2793008 w/Freecom Parallel Cable rev.903 (FRIQ)
- Backpack CD-RW 222011 and CD-RW 19350 (BPCK6)
The following bugs in low-level protocol drivers were found and will
be fixed later:
Note: EPP-32 mode is buggy in EPAT - and also in all other protocol
drivers - they don't handle non-multiple-of-4 block transfers
correctly. This causes problems with LS-120 drive.
There is also another bug in EPAT: EPP modes don't work unless a 4-bit
or 8-bit mode is used first (probably some initialization missing?).
Once the device is initialized, EPP works until power cycle.
So after device power on, you have to:
echo "parport0 epat 0" >/sys/bus/pata_parport/new_device
echo pata_parport.0 >/sys/bus/pata_parport/delete_device
echo "parport0 epat 4" >/sys/bus/pata_parport/new_device
(autoprobe will initialize correctly as it tries the slowest modes
first but you'll get the broken EPP-32 mode)
Note: EPP modes are buggy in FRPW, only modes 0 and 1 work.

Thread [1] reported back in 2012 problems with enabling FUA for 3
different drives. Add these drives to ata_device_blacklist[] to mark
them with the ATA_HORKAGE_NO_FUA flag. To be conservative and avoid
problems on old systems, the model number for the three new entries
are defined as to widely match all drives in the same product line.

If a user issues a write command with the FUA bit set for a device with
NCQ support disabled (that is, the device queue depth was set to 1), the
LBA 48 command WRITE DMA FUA EXT must be used. However,
ata_build_rw_tf() ignores this and first tests if LBA 28 can be used
based on the write command sector and number of blocks. That is, for
small FUA writes at low LBAs, ata_rwcmd_protocol() will cause the write
to fail.
Fix this by preventing the use of LBA 28 for any FUA write request.
Given that the WRITE MULTI FUA EXT command is marked as obsolete in the
ATA specification since ACS-3 (published in 2013), remove the
ATA_CMD_WRITE_MULTI_FUA_EXT command from the ata_rw_cmds array.

Move the detection of a device FUA support from
ata_scsiop_mode_sense()/ata_dev_supports_fua() to device scan time in
ata_dev_configure().
The function ata_dev_config_fua() is introduced to detect if a device
supports FUA and this support is indicated using the new device flag
ATA_DFLAG_FUA.
In order to blacklist known buggy devices, the horkage flag
ATA_HORKAGE_NO_FUA is introduced. Similarly to other horkage flags, the
libata.force= arguments "fua" and "nofua" are also introduced to allow
a user to control this horkage flag through the "force" libata
module parameter.
The ATA_DFLAG_FUA device flag is set only and only if all the following
conditions are met:
* libata.fua module parameter is set to 1
* The device supports the WRITE DMA FUA EXT command,
* The device is not marked with the ATA_HORKAGE_NO_FUA flag, either from
the blacklist or set by the user with libata.force=nofua
* The device supports NCQ (while this is not mandated by the standards,
this restriction is introduced to avoid problems with older non-NCQ
devices).
Enabling or diabling libata FUA support for all devices can now also be
done using the "force=[no]fua" module parameter when libata.fua is set
to 1.

For SCSI ML byte:
In the case where a command is completed via libata EH:
irq -> ata_qc_complete() -> ata_qc_schedule_eh()
irq done
... -> ata_do_eh() -> ata_eh_link_autopsy() -> ata_eh_finish() ->
ata_eh_qc_complete() -> __ata_eh_qc_complete() -> __ata_qc_complete() ->
qc->complete_fn() (ata_scsi_qc_complete()) -> ata_qc_done() ->
qc->scsidone() (empty stub)
... -> scsi_eh_finish_cmd() -> scsi_eh_flush_done_q() ->
scsi_finish_command()
ata_eh_link_autopsy() will call ata_eh_analyze_tf(), which calls
scsi_check_sense(), which sets the SCSI ML byte.
Since ata_scsi_qc_complete() is called after scsi_check_sense() when
a command is completed via libata EH, we cannot simply overwrite the
SCSI ML byte that was set earlier in the call chain.
For SCSI status byte:
When a SCSI command is prepared using scsi_prepare_cmd(), it sets
cmd->result to 0. (SAM_STAT_GOOD is defined as 0x0).
Likewise, when a command is requeued from SCSI EH, scsi_queue_insert()
is called, which sets cmd->result to 0.
A SCSI command thus always has a GOOD status by default when being
sent to libata.
If libata fetches sense data from the device, it will call
ata_scsi_set_sense(), which will set the status byte to
SAM_STAT_CHECK_CONDITION, if the caller deems that the status should be
a check condition.
ata_scsi_qc_complete() should therefore never overwrite the existing
status byte, because if it is != GOOD, it was set by libata itself,
for a reason.
For the host byte:
When libata abort commands, because of a NCQ error, it will schedule
SCSI EH for all QCs using blk_abort_request(), which will all end up in
scsi_timeout(), which will call scsi_abort_command(). scsi_timeout()
sets DID_TIME_OUT regardless if a command was aborted or timed out.
If we don't clear the DID_TIME_OUT byte for the QC that caused the
NCQ error, that QC will be reported as a timed out command, instead
of being reported as a NCQ error.
For a command that actually timed out, DID_TIME_OUT would be fine to
keep, but libata has its own way of detecting that a command timed out
(see ata_scsi_cmd_error_handler()), and sets AC_ERR_TIMEOUT if that is
the case. libata will retry timed out commands.
We could clear DID_TIME_OUT only for the QC that caused the NCQ error,
but since libata has its own way of detecting timeouts, simply clear it
always.
Note that the existing ata_scsi_qc_complete() code does:
cmd->result = SAM_STAT_CHECK_CONDITION or cmd->result = SAM_STAT_GOOD.
This WILL clear the host byte. So us clearing the host byte
unconditionally is in line with the existing libata behavior.

ata_dev_configure() starts off by clearing all flags in ATA_DFLAG_CFG_MASK:
dev->flags &= ~ATA_DFLAG_CFG_MASK;
ata_dev_configure() then calls ata_dev_config_lba() which calls
ata_dev_config_ncq().
ata_dev_config_ncq() will set the correct ATA_DFLAGs depending on what is
actually supported.
Since these flags are set by ata_dev_configure(), they should be in
ATA_DFLAG_CFG_MASK and not in ATA_DFLAG_INIT_MASK.
ATA_DFLAG_NCQ_PRIO_ENABLED is set via sysfs, is should therefore not be in
ATA_DFLAG_CFG_MASK. It also cannot be in ATA_DFLAG_INIT_MASK, because
ata_eh_schedule_probe() calls ata_dev_init(), which will clear all flags in
ATA_DFLAG_INIT_MASK.
This means that ATA_DFLAG_NCQ_PRIO_ENABLED (the value the user sets via
sysfs) would get silently cleared if ata_eh_schedule_probe() is called.
While that should only happen in certain circumstances, it still doesn't
seem right that it can get silently cleared.
(ata_dev_config_ncq_prio() will still clear the ATA_DFLAG_NCQ_PRIO_ENABLED
flag if ATA_DFLAG_NCQ_PRIO is suddenly no longer supported after a
revalidation.)
Because of this, move ATA_DFLAG_NCQ_PRIO_ENABLED to be outside of both
ATA_DFLAG_CFG_MASK and ATA_DFLAG_INIT_MASK.

In AHCI specification 1.3.1:
"5.5.3 Processing Completed Commands"
"For each port that has an interrupt pending:
1. Software determines the cause of the interrupt by reading the PxIS
register. It is possible for multiple bits to be set.
2. Software clears appropriate bits in the PxIS register corresponding
to the cause of the interrupt.
3. Software clears the interrupt bit in IS.IPS corresponding to the port.
4. If executing non-queued commands, software reads the PxCI register,
and compares the current value to the list of commands previously
issued by software that are still outstanding. If executing native
queued commands, software reads the PxSACT register and compares the
current value to the list of commands previously issued by software.
Software completes with success any outstanding command whose
corresponding bit has been cleared in the respective register. PxCI
and PxSACT are volatile registers; software should only use their
values to determine commands that have completed, not to determine
which commands have previously been issued.
5. If there were errors, noted in the PxIS register, software performs
error recovery actions (see section 6.2.2)."
The documentation for the PxSACT shadow register in AHCI:
"The device clears bits in this field by sending a Set Device Bits FIS
to the host. The HBA clears bits in this field that are set to ‘1’ in
the SActive field of the Set Device Bits FIS. The HBA only clears bits
that correspond to native queued commands that have completed
successfully."
Additionally, in SATA specification 3.5a:
"11.15 FPDMA QUEUED command protocol"
"DFPDMAQ11: ERROR
Halt command processing and transmit Set Device Bits FIS to host
with the ERR bit in Status field set to one, Interrupt bit set to one,
ATA error code set to one in the ERROR field, bits in ACT field cleared
to zero for any outstanding queued commands, and bits set to one
for any successfully completed queued commands that completion
notification not yet delivered."
I.e. even when the HBA triggers an error interrupt, the HBA will still
clear successfully completed commands in PxSACT. Commands that did not
complete successfully will still have its bit set in PxSACT.
(Which means the command that caused the NCQ error and queued commands
that had not yet finished at the time when the NCQ error occurred.)
Additionally, for a HBA that does not have the libata flag
AHCI_HFLAG_MULTI_MSI set, all ap->locks will point to host->lock, which
means that IRQs will be disabled for one port while another port's IRQ
handler is running. The HBA will still receive FISes from the device,
even if IRQs on the HBA itself are disabled. What can thus e.g. receive
a FIS that completes several commands successfully, followed by a FIS
that does (or does not) complete additional commands with the error bit
set, to indicate that at least one command was aborted.
Therefore, modify ahci_handle_port_interrupt() using the new helper
ahci_qc_complete() to complete the commands that have already been
signaled as successfully through a regular completion SDB FIS, as not
doing so would simply cause successfully completed commands to be
retried for no good reason.

Currently, the status is being read for each QC, inside
ata_qc_complete(), which means that QCs being completed by
ata_qc_complete_multiple() (i.e. multiple QCs completed during a single
interrupt), can have different status and error bits set. This is
because the FIS Receive Area will get updated as soon as the HBA
receives a new FIS from the device in the NCQ case.
Here is an example of the problem:
ata14.00: ata_qc_complete_multiple: done_mask: 0x180000
qc tag: 19 cmd: 0x61 flags: 0x11b err_mask: 0x0 tf->status: 0x40
qc tag: 20 cmd: 0x61 flags: 0x11b err_mask: 0x0 tf->status: 0x43
A print in ata_qc_complete_multiple(), shows that done_mask is: 0x180000
which means that tag 19 and 20 were completed. Another print in
ata_qc_complete(), after the call to fill_result_tf(), shows that tag 19
and 20 have different status values, even though they were completed in
the same ata_qc_complete_multiple() call.
If PMP is not enabled, simply read the status and error once, before
calling ata_qc_complete() for each QC. Without PMP, we know that all QCs
must share the same status and error values.
If PMP is enabled, we also read the status before calling
ata_qc_complete(), however, we still read the status for each QC, since
the QCs can belong to different PMP links (which means that the QCs
does not necessarily share the same status and error values).
Do all this by introducing the new port operation .qc_ncq_fill_rtf. If
set, this operation is called in ata_qc_complete_multiple() to set the
result tf for all completed QCs signaled by the last SDB FIS received.
QCs that have their result tf filled are marked with the new flag
ATA_QCFLAG_RTF_FILLED so that any later execution of the qc_fill_rtf
port operation does nothing (e.g. when called from ata_qc_complete()).

The name ATA_QCFLAG_FAILED is misleading since it does not mean that a
QC completed in error, or that it didn't complete at all. It means that
libata decided to schedule EH for the QC, so the QC is now owned by the
libata error handler (EH).
The normal execution path is responsible for not accessing a QC owned
by EH. libata core enforces the rule by returning NULL from
ata_qc_from_tag() for QCs owned by EH.
It is quite easy to mistake that a QC marked with ATA_QCFLAG_FAILED was
an error. However, a QC that was actually an error is instead indicated
by having qc->err_mask set. E.g. when we have a NCQ error, we abort all
QCs, which currently will mark all QCs as ATA_QCFLAG_FAILED. However, it
will only be a single QC that is an error (i.e. has qc->err_mask set).
Rename ATA_QCFLAG_FAILED to ATA_QCFLAG_EH to more clearly highlight that
this flag simply means that a QC is now owned by EH. This new name will
not mislead to think that the QC was an error (which is instead
indicated by having qc->err_mask set).
This also makes it more obvious that the EH code skips all QCs that do
not have ATA_QCFLAG_EH set (rather than ATA_QCFLAG_FAILED), since the EH
code should simply only care about QCs that are owned by EH itself.

Starting from ICL, the default for MIPI GPIO sequences seems to be using
native GPIOs i.e. GPIOs available in the GPU. These native GPIOs reuse
many pins that quite frankly seem scary to poke based on the VBT
sequences. We pretty much have to trust that the board is configured
such that the relevant HPD, PP_CONTROL and GPIO bits aren't used for
anything else.
MIPI sequence v4 also adds a flag to fall back to non-native sequences.
v5:
- Wrap SHOTPLUG_CTL_DDI modification in spin_lock() in icp_irq_handler()
too (Ville)
- References instead of Closes issue 6131 because this does not fix everything
v4:

v3:
- Fix -Wbitwise-conditional-parentheses (kernel test robot <lkp@intel.com>)
v2:
- Fix HPD pin output set (impacts GPIOs 0 and 5)
- Fix GPIO data output direction set (impacts GPIOs 4 and 9)

Guoqing Jiang reports that openSUSE cannot compile the kernel rpm due
to "BuildRequires: elfutils-libelf-devel" added by commit 8818039f95
("kbuild: add ability to make source rpm buildable using koji").
The relevant package name in openSUSE is libelf-devel.
Add it as an alternative package.
BTW, if it is impossible to solve the build requirement, the final
resort would be:
$ make RPMOPTS=--nodeps rpm-pkg
This passes --nodeps to the rpmbuild command so it will not verify
build dependencies. This is useful to test rpm builds on non-rpm
system. On Debian/Ubuntu, for example, you can install rpmbuild by
'apt-get install rpm'.
NOTE1:
Likewise, it is possible to bypass the build dependency check for
debian package builds:
$ make DPKG_FLAGS=-d deb-pkg
NOTE2:
The 'or' operator is supported since RPM 4.13. So, old distros such
as CentOS 7 will break. I suggest installing newer rpmbuild in such
cases.

commit 3d57e1b7b1 ("kbuild: refactor the prerequisites of the modpost
rule") moved 'vmlinux.o' inside modpost-args, possibly before some of
the other options. However, getopt() in musl libc follows POSIX and
stops looking for options upon reaching the first non-option argument.
As a result, the '-T' option is misinterpreted as a positional argument,
and the build fails:
make -f ./scripts/Makefile.modpost
scripts/mod/modpost -E -o Module.symvers vmlinux.o -T modules.order
-T: No such file or directory
make[1]: *** [scripts/Makefile.modpost:137: Module.symvers] Error 1
make: *** [Makefile:1960: modpost] Error 2
The fix is to move all options before 'vmlinux.o' in modpost-args.

Dennis Gilmore reports that the BuildID is missing in the arm64 vmlinux
since commit 994b7ac169 ("arm64: remove special treatment for the
link order of head.o").
The issue is that the type of .notes section, which contains the BuildID,
changed from NOTES to PROGBITS.
Ard Biesheuvel figured out that whichever object gets linked first gets
to decide the type of a section. The PROGBITS type is the result of the
compiler emitting .note.GNU-stack as PROGBITS rather than NOTE.
While Ard provided a fix for arm64, I want to fix this globally because
the same issue is happening on riscv since commit 2348e6bf44 ("riscv:
remove special treatment for the link order of head.o"). This problem
will happen in general for other architectures if they start to drop
unneeded entries from scripts/head-object-list.txt.
Discard .note.GNU-stack in include/asm-generic/vmlinux.lds.h.

In the case where a firmware file is too large (e.g. someone
downloaded a web page ASCII dump from github...), the firmware object
is released but the pointer is not zerod. If no other firmware file
was found then release would be called again leading to a double kfree.
Also, the size check was only being applied to the initial firmware
load not any of the subsequent attempts. So move the check into a
wrapper that is used for all loads.

The catch-all evict can fail due to object lock contention, since it
only goes as far as trylocking the object, due to us already holding the
vm->mutex. Doing a full object lock here can deadlock, since the
vm->mutex is always our inner lock. Add another execbuf pass which drops
the vm->mutex and then tries to grab the object will the full lock,
before then retrying the eviction. This should be good enough for now to
fix the immediate regression with userspace seeing -ENOSPC from execbuf
due to contended object locks during GTT eviction.

Commands like Write Zeros can change the contents of a namespaces without
actually transferring data. To protect against this, check the Commands
Supported and Effects log is supported by the controller for any
unprivileg command passthrough and refuse unprivileged passthrough if the
command has any effects that can change data or metadata.
Note: While the Commands Support and Effects log page has only been
mandatory since NVMe 2.0, it is widely supported because Windows requires
it for any command passthrough from userspace.
