commit 7c3151585730b7095287be8162b846d31e6eee61 upstream.
The elf-fdpic loader hard sets the process personality to either
PER_LINUX_FDPIC for true elf-fdpic binaries or to PER_LINUX for normal ELF
binaries (in this case they would be constant displacement compiled with
-pie for example). The problem with that is that it will lose any other
bits that may be in the ELF header personality (such as the "bug
emulation" bits).
On the ARM architecture the ADDR_LIMIT_32BIT flag is used to signify a
normal 32bit binary - as opposed to a legacy 26bit address binary. This
matters since start_thread() will set the ARM CPSR register as required
based on this flag. If the elf-fdpic loader loses this bit the process
will be mis-configured and crash out pretty quickly.
Modify elf-fdpic loader personality setting so that it preserves the upper
three bytes by using the SET_PERSONALITY macro to set it. This macro in
the generic case sets PER_LINUX and preserves the upper bytes.
Architectures can override this for their specific use case, and ARM does
exactly this.
The problem shows up quite easily running under qemu using the ARM
architecture, but not necessarily on all types of real ARM hardware. If
the underlying ARM processor does not support the legacy 26-bit addressing
mode then everything will work as expected.

commit 753a4d531bc518633ea88ac0ed02b25a16823d51 upstream.
On certain SATA controllers, softreset fails after wakeup from S2RAM with
the message "softreset failed (1st FIS failed)", sometimes resulting in
drives not being detected again. With the increased timeout, this issue
is avoided. Instead, "softreset failed (device not ready)" is now
logged 1-2 times; this later failure seems to cause fewer problems
however, and the drives are detected reliably once they've spun up and
the probe is retried.
The issue was observed with the primary SATA controller of the QNAP
TS-453B, which is an "Intel Corporation Celeron/Pentium Silver Processor
SATA Controller [8086:31e3] (rev 06)" integrated in the Celeron J4125 CPU,
and the following drives:
- Seagate IronWolf ST12000VN0008
- Seagate IronWolf ST8000NE0004
The SATA controller seems to be more relevant to this issue than the
drives, as the same drives are always detected reliably on the secondary
SATA controller on the same board (an ASMedia 106x) without any "softreset
failed" errors even without the increased timeout.

commit 75e2bd5f1ede42a2bc88aa34b431e1ace8e0bea0 upstream.
libsas does its own domain based power management of ports. For such
ports, libata should not use a device type defining power management
operations as executing these operations for suspend/resume in addition
to libsas calls to ata_sas_port_suspend() and ata_sas_port_resume() is
not necessary (and likely dangerous to do, even though problems are not
seen currently).
Introduce the new ata_port_sas_type device_type for ports managed by
libsas. This new device type is used in ata_tport_add() and is defined
without power management operations.

commit 84d76529c650f887f1e18caee72d6f0589e1baf9 upstream.
Whenever an ATA adapter driver is removed (e.g. rmmod),
ata_port_detach() is called repeatedly for all the adapter ports to
remove (unload) the devices attached to the port and delete the port
device itself. Removing of devices is done using libata EH with the
ATA_PFLAG_UNLOADING port flag set. This causes libata EH to execute
ata_eh_unload() which disables all devices attached to the port.
ata_port_detach() finishes by calling scsi_remove_host() to remove the
scsi host associated with the port. This function will trigger the
removal of all scsi devices attached to the host and in the case of
disks, calls to sd_shutdown() which will flush the device write cache
and stop the device. However, given that the devices were already
disabled by ata_eh_unload(), the synchronize write cache command and
start stop unit commands fail. E.g. running "rmmod ahci" with first
removing sd_mod results in error messages like:
ata13.00: disable device
sd 0:0:0:0: [sda] Synchronizing SCSI cache
sd 0:0:0:0: [sda] Synchronize Cache(10) failed: Result: hostbyte=DID_BAD_TARGET driverbyte=DRIVER_OK
sd 0:0:0:0: [sda] Stopping disk
sd 0:0:0:0: [sda] Start/Stop Unit failed: Result: hostbyte=DID_BAD_TARGET driverbyte=DRIVER_OK
Fix this by removing all scsi devices of the ata devices connected to
the port before scheduling libata EH to disable the ATA devices.

commit 3b8e0af4a7a331d1510e963b8fd77e2fca0a77f1 upstream.
The function ata_port_request_pm() checks the port flag
ATA_PFLAG_PM_PENDING and calls ata_port_wait_eh() if this flag is set to
ensure that power management operations for a port are not scheduled
simultaneously. However, this flag check is done without holding the
port lock.
Fix this by taking the port lock on entry to the function and checking
the flag under this lock. The lock is released and re-taken if
ata_port_wait_eh() needs to be called. The two WARN_ON() macros checking
that the ATA_PFLAG_PM_PENDING flag was cleared are removed as the first
call is racy and the second one done without holding the port lock.

A user reported some issues with smaller file systems that get very
full. While investigating this issue I noticed that df wasn't showing
100% full, despite having 0 chunk space and having < 1MiB of available

This turns out to be an overflow issue, we're doing:
total_available_metadata_space - SZ_4M < global_block_rsv_size
to determine if there's not enough space to make metadata allocations,
which overflows if total_available_metadata_space is < 4M. Fix this by
checking to see if our available space is greater than the 4M threshold.
This makes df properly report 100% usage on the file system.

commit 1e0cb399c7653462d9dadf8ab9425337c355d358 upstream.
It was discovered that the ring buffer polling was incorrectly stating
that read would not block, but that's because polling did not take into
account that reads will block if the "buffer-percent" was set. Instead,
the ring buffer polling would say reads would not block if there was any
data in the ring buffer. This was incorrect behavior from a user space
point of view. This was fixed by commit 42fb0a1e84ff by having the polling
code check if the ring buffer had more data than what the user specified
"buffer percent" had.
The problem now is that the polling code did not register itself to the
writer that it wanted to wait for a specific "full" value of the ring
buffer. The result was that the writer would wake the polling waiter
whenever there was a new event. The polling waiter would then wake up, see
that there's not enough data in the ring buffer to notify user space and
then go back to sleep. The next event would wake it up again.
Before the polling fix was added, the code would wake up around 100 times
for a hackbench 30 benchmark. After the "fix", due to the constant waking
of the writer, it would wake up over 11,0000 times! It would never leave
the kernel, so the user space behavior was still "correct", but this
definitely is not the desired effect.
To fix this, have the polling code add what it's waiting for to the
"shortest_full" variable, to tell the writer not to wake it up if the
buffer is not as full as it expects to be.
Note, after this fix, it appears that the waiter is now woken up around 2x
the times it was before (~200). This is a tremendous improvement from the
11,000 times, but I will need to spend some time to see why polling is
more aggressive in its wakeups than the read blocking code.

In nilfs_gccache_submit_read_data(), brelse(bh) is called to drop the
reference count of bh when the call to nilfs_dat_translate() fails. If
the reference count hits 0 and its owner page gets unlocked, bh may be
freed. However, bh->b_page is dereferenced to put the page after that,
which may result in a use-after-free bug. This patch moves the release
operation after unlocking and putting the page.
NOTE: The function in question is only called in GC, and in combination
with current userland tools, address translation using DAT does not occur
in that function, so the code path that causes this issue will not be
executed. However, it is possible to run that code path by intentionally
modifying the userland GC library or by calling the GC ioctl directly.

smack_dentry_create_files_as() determines whether transmuting should occur
based on the label of the parent directory the new inode will be added to,
and not the label of the directory where it is created.
This helps for example to do transmuting on overlayfs, since the latter
first creates the inode in the working directory, and then moves it to the
correct destination.
However, despite smack_dentry_create_files_as() provides the correct label,
smack_inode_init_security() does not know from passed information whether
or not transmuting occurred. Without this information,
smack_inode_init_security() cannot set SMK_INODE_CHANGED in smk_flags,
which will result in the SMACK64TRANSMUTE xattr not being set in
smack_d_instantiate().
Thus, add the smk_transmuted field to the task_smack structure, and set it
in smack_dentry_create_files_as() to smk_task if transmuting occurred. If
smk_task is equal to smk_transmuted in smack_inode_init_security(), act as
if transmuting was successful but without taking the label from the parent
directory (the inode label was already set correctly from the current
credentials in smack_inode_alloc_security()).

watchdog not to trigger reboot anymore when NO_REBOOT flag is initially
cleared using this option (in QEMU command line):
-global ICH9-LPC.noreboot=false
The problem with the commit is that it left the unconditional setting of
NO_REBOOT that is not cleared anymore when the kernel keeps pinging the
watchdog (as opposed to the previous code that called iTCO_wdt_stop()
that cleared it).
Fix this so that we only set NO_REBOOT if the watchdog was not initially
running.

[ Upstream commit 80cc944eca4f0baa9c381d0706f3160e491437f2 ]
ata_scsi_port_error_handler() starts off by clearing ATA_PFLAG_EH_PENDING,
before calling ap->ops->error_handler() (without holding the ap->lock).
If an error IRQ is received while ap->ops->error_handler() is running,
the irq handler will set ATA_PFLAG_EH_PENDING.
Once ap->ops->error_handler() returns, ata_scsi_port_error_handler()
checks if ATA_PFLAG_EH_PENDING is set, and if it is, another iteration
of ATA EH is performed.
The problem is that ATA_PFLAG_EH_PENDING is not only cleared by
ata_scsi_port_error_handler(), it is also cleared by ata_eh_reset().
ata_eh_reset() is called by ap->ops->error_handler(). This additional
clearing done by ata_eh_reset() breaks the whole retry logic in
ata_scsi_port_error_handler(). Thus, if an error IRQ is received while
ap->ops->error_handler() is running, the port will currently remain
frozen and will never get re-enabled.
The additional clearing in ata_eh_reset() was introduced in commit
1e641060c4b5 ("libata: clear eh_info on reset completion").
Looking at the original error report:
https://marc.info/?l=linux-ide&m=124765325828495&w=2
We can see the following happening:
[ 1.074659] ata3: XXX port freeze
[ 1.074700] ata3: XXX hardresetting link, stopping engine
[ 1.074746] ata3: XXX flipping SControl
[ 1.411471] ata3: XXX irq_stat=400040 CONN|PHY
[ 1.411475] ata3: XXX port freeze
[ 1.420049] ata3: XXX starting engine
[ 1.420096] ata3: XXX rc=0, class=1
[ 1.420142] ata3: XXX clearing IRQs for thawing
[ 1.420188] ata3: XXX port thawed
[ 1.420234] ata3: SATA link up 3.0 Gbps (SStatus 123 SControl 300)
We are not supposed to be able to receive an error IRQ while the port is
frozen (PxIE is set to 0, i.e. all IRQs for the port are disabled).
AHCI 1.3.1 section 10.7.1.1 First Tier (IS Register) states:
"Each bit location can be thought of as reporting a '1' if the virtual
"interrupt line" for that port is indicating it wishes to generate an
interrupt. That is, if a port has one or more interrupt status bit set,
and the enables for those status bits are set, then this bit shall be set."
Additionally, AHCI state P:ComInit clearly shows that the state machine
will only jump to P:ComInitSetIS (which sets IS.IPS(x) to '1'), if PxIE.PCE
is set to '1'. In our case, PxIE is set to 0, so IS.IPS(x) won't get set.
So IS.IPS(x) only gets set if PxIS and PxIE is set.
AHCI 1.3.1 section 10.7.1.1 First Tier (IS Register) also states:
"The bits in this register are read/write clear. It is set by the level of
the virtual interrupt line being a set, and cleared by a write of '1' from
the software."
So if IS.IPS(x) is set, you need to explicitly clear it by writing a 1 to
IS.IPS(x) for that port.
Since PxIE is cleared, the only way to get an interrupt while the port is
frozen, is if IS.IPS(x) is set, and the only way IS.IPS(x) can be set when
the port is frozen, is if it was set before the port was frozen.
However, since commit 737dd811a3db ("ata: libahci: clear pending interrupt
status"), we clear both PxIS and IS.IPS(x) after freezing the port, but
before the COMRESET, so the problem that commit 1e641060c4b5 ("libata:
clear eh_info on reset completion") fixed can no longer happen.
Thus, revert commit 1e641060c4b5 ("libata: clear eh_info on reset
completion"), so that the retry logic in ata_scsi_port_error_handler()
works once again. (The retry logic is still needed, since we can still
get an error IRQ _after_ the port has been thawed, but before
ata_scsi_port_error_handler() takes the ap->lock in order to check
if ATA_PFLAG_EH_PENDING is set.)

If the kernel preemption model is PREEMPT_NONE and there are many cpus

To avoid it, call cond_resched() after each cpu buffer allocation.

"When cleared to ‘0’, software must not allow the HBA to initiate

transitions to the Partial state via agressive link power management nor
the PxCMD.ICC field in each port, and the PxSCTL.IPM field in each port
must be programmed to disallow device initiated Partial requests."
Ensure that we always set the corresponding bits in PxSCTL.IPM, such that
a device is not allowed to initiate transitions to power states which are
unsupported by the HBA.
DevSleep is always initiated by the HBA, however, for completeness, set the
corresponding bit in PxSCTL.IPM such that agressive link power management
cannot transition to DevSleep if DevSleep is not supported.
sata_link_scr_lpm() is used by libahci, ata_piix and libata-pmp.
However, only libahci has the ability to read the CAP/CAP2 register to see
if these features are supported. Therefore, in order to not introduce any
regressions on ata_piix or libata-pmp, create flags that indicate that the
respective feature is NOT supported. This way, the behavior for ata_piix
and libata-pmp should remain unchanged.

[ Upstream commit eb09074bdb05ffd6bfe77f8b4a41b76ef78c997b ]
The touchpad of this device is both connected via PS/2 and i2c. This causes
strange behavior when both driver fight for control. The easy fix is to
prevent the PS/2 driver from accessing the mouse port as the full feature
set of the touchpad is only supported in the i2c interface anyway.
The strange behavior in this case is, that when an external screen is
connected and the notebook is closed, the pointer on the external screen is
moving to the lower right corner. When the notebook is opened again, this
movement stops, but the touchpad clicks are unresponsive afterwards until
reboot.
