aio: Fix locking in aio_poll()
wake_up_locked() may but does not have to be called with interrupts
disabled. Since the fuse filesystem calls wake_up_locked() without
disabling interrupts aio_poll_wake() may be called with interrupts
enabled. Since the kioctx.ctx_lock may be acquired from IRQ context,
all code that acquires that lock from thread context must disable
interrupts. Hence change the spin_trylock() call in aio_poll_wake()
into a spin_trylock_irqsave() call. This patch fixes the following
lockdep complaint:

copy_mount_string: Limit string length to PATH_MAX
On ppc64le, When a string with PAGE_SIZE - 1 (i.e. 64k-1) length is passed as a "filesystem type" argument to the mount(2) syscall, copy_mount_string() ends up allocating 64k (the PAGE_SIZE on ppc64le) worth of space for holding the string in kernel's address space. Later, in set_precision() (invoked by get_fs_type() -> __request_module() -> vsnprintf()), we end up assigning strlen(fs-type-string) i.e. 65535 as the value to 'struct printf_spec'->precision member. This field has a width of 16 bits and it is a signed data type. Hence an invalid value ends up getting assigned. This causes the "WARN_ONCE(spec->precision != prec, "precision %d too large", prec)" statement inside set_precision() to be executed. This commit fixes the bug by limiting the length of the string passed by copy_mount_string() to strndup_user() to PATH_MAX.

cgroup: saner refcounting for cgroup_root
* make the reference from superblock to cgroup_root counting - do cgroup_put() in cgroup_kill_sb() whether we'd done percpu_ref_kill() or not; matching grab is done when we allocate a new root. That gives the same refcounting rules for all callers of cgroup_do_mount() - a reference to cgroup_root has been grabbed by caller and it either is transferred to new superblock or dropped. * have cgroup_kill_sb() treat an already killed refcount as "just don't bother killing it, then". * after successful cgroup_do_mount() have cgroup1_mount() recheck if we'd raced with mount/umount from somebody else and cgroup_root got killed. In that case we drop the superblock and bugger off with -ERESTARTSYS, same as if we'd found it in the list already dying. * don't bother with delayed initialization of refcount - it's unreliable and not needed. No need to prevent attempts to bump the refcount if we find cgroup_root of another mount in progress - sget will reuse an existing superblock just fine and if the other sb manages to die before we get there, we'll catch that immediately after cgroup_do_mount(). * don't bother with kernfs_pin_sb() - no need for doing that either.

kernel/sys.c: Clarify that UNAME26 does not generate unique versions anymore
UNAME26 is a mechanism to report Linux's version as 2.6.x, for compatibility with old/broken software. Due to the way it is implemented, it would have to be updated after 5.0, to keep the resulting versions unique. Linus Torvalds argued: "Do we actually need this? I'd rather let it bitrot, and just let it return random versions. It will just start again at 2.4.60, won't it? Anybody who uses UNAME26 for a 5.x kernel might as well think it's still 4.x. The user space is so old that it can't possibly care about differences between 4.x and 5.x, can it? The only thing that matters is that it shows "2.4.<largeenough>", which it will do regardless" Signed-off-by: Jonathan Neuschäfer <j.neuschaefer@gmx.net> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> |

ARM: SoC fixes
A bigger batch than I anticipated this week, for two reasons:
- Some fallout on Davinci from board file -> DTB conversion, that also
includes a few longer-standing fixes (i.e. not recent regressions).
- drivers/reset material that has been in linux-next for a while, but
didn't get sent to us until now for a variety of reasons (maintainer out
sick, holidays, etc). There's a functional dependency in there such that
one platform (Altera's SoCFPGA) won't boot without one of the patches;
instead of reverting the patch that got merged, I looked at this set
and decided it was small enough that I'll pick it up anyway. If you
disagree I can revisit with a smaller set.
That being said, there's also a handful of the usual stuff:
- Fix for a crash on Armada 7K/8K when the kernel touches PSCI-reserved
memory
- Fix for PCIe reset on Macchiatobin (Armada 8K development board, what
this email is sent from in fact :)
- Enable a few new-merged modules for Amlogic in arm64 defconfig
- Error path fixes on Integrator
- Build fix for Renesas and Qualcomm
- Initialization fix for Renesas RZ/G2E
+ A few more fixlets.

Driver core fixes for 5.0-rc2
Here is one small sysfs change, and a documentation update for 5.0-rc2 The sysfs change moves from using BUG_ON to WARN_ON, as discussed in an email thread on lkml while trying to track down another driver bug. sysfs should not be crashing and preventing people from seeing where they went wrong. Now it properly recovers and warns the developer. The documentation update removes the use of BUS_ATTR() as the kernel is moving away from this to use the specific BUS_ATTR_RW() and friends instead. There are pending patches in all of the different subsystems to remove the last users of this macro, but for now, don't advertise it should be used anymore to keep new ones from being introduced. Both have been in linux-next with no reported issues.

remove dma_zalloc_coherent
We've always had a weird situation around dma_zalloc_coherent. To safely support mapping the allocations to userspace major architectures like x86 and arm have always zeroed allocations from dma_alloc_coherent, but a couple other architectures were missing that zeroing either always or in corner cases. Then later we grew anothe dma_zalloc_coherent interface to explicitly request zeroing, but that just added __GFP_ZERO to the allocation flags, which for some allocators that didn't end up using the page allocator ended up being a no-op and still not zeroing the allocations. So for this merge window I fixed up all remaining architectures to zero the memory in dma_alloc_coherent, and made dma_zalloc_coherent a no-op wrapper around dma_alloc_coherent, which fixes all of the above issues. dma_zalloc_coherent is now pointless and can go away, and Luis helped me writing a cocchinelle script and patch series to kill it, which I think we should apply now just after -rc1 to finally settle these issue. -----BEGIN PGP SIGNATURE----- iQI/BAABCgApFiEEgdbnc3r/njty3Iq9D55TZVIEUYMFAlw6LV0LHGhjaEBsc3Qu ZGUACgkQD55TZVIEUYPd1hAAshbVLVIUg750CQoKD5sk44/IW7klkQUnzcp9ueOY /GIYS/ils8q9DSITAyMJxHKpjt1EEVlavWLvYLlfpkDfLaVGMUJu+zKGaolhU5F6 OuldJKZV6tWrC7zGVl+09y5CAyelVxLyuD09I+QYnHUIO9ljgZHB2+W3ezOFxBRD FjrQRuFY6Xpr1F42zWc4aJrgACffH761pLx3fbJlIs8aEInWKqDbuyL6Lg71BRXh kHKt0DQxFxklyQmqaYyDesujjXUysweAFLNxgN9GSrlWBR8GE3qJpsSrIzjX5k8w WKzbypYqVQepI3zYCN5EoCAoiHBFZXPSNHCoXAH6tHjYwgQ3uoDpzxEKJOEykO4i 1+kcJh3ArQZA/BsMBf3I/CNMsxvBuC3/QKFMcs/7pKx1ABoumSBSIpqB4pG4NU+o fxRBHKjqbILufWKReb2PuRXiPpddwuo0vg70U0FK2aWZrClRYEpBdExPKrBUAG34 WtQCGA0YFXV/kAgPPmOvnPlwpYM2ZrVLVl5Ct2diR5QaLee3o1GiStQm0LuspRzk HSzVyCYdKRxH4zkEBzKUn/PuyYLoMRyPP4PQ3R/xlQrFqvv6FeiGYnow89+1JpUp 2qWg5vU1aLM7/WXnyVGDED3T42eZREi/uMPQIADXqRIVC7e43/eKcLF06n0lIWh9 usg= =VIBB -----END PGP SIGNATURE----- Merge tag 'remove-dma_zalloc_coherent-5.0' of git://git.infradead.org/users/hch/dma-mapping Pull dma_zalloc_coherent() removal from Christoph Hellwig: "We've always had a weird situation around dma_zalloc_coherent.

ata: ahci: mvebu: add Armada 3700 initialization needed for S2RAM
A3700 comphy initialization is done in the firmware (TF-A). Looking at the SATA PHY initialization routine, there is a comment about "vendor specific" registers. Two registers are mentioned. They are not initialized there in the firmware because they are AHCI related, while the firmware at this location does only PHY configuration. The solution to avoid doing such initialization is relying on U-Boot. While this work at boot time, U-Boot is definitely not going to run during a resume after suspending to RAM. Two possible solutions were considered: * Fixing the firmware. * Fixing the kernel driver. The first solution would take ages to propagate, while the second solution is easy to implement as the driver as been a little bit reworked to prepare for such platform configuration. Hence, this patch adds an Armada 3700 configuration function to set these two registers both at boot time (in the probe) and after a suspend (in the resume path).

ata: libahci_platform: comply to PHY framework
Current implementation of the libahci does not take into account the new PHY framework. Correct the situation by adding a call to phy_set_mode() before phy_power_on(). PHYs should also be handled at suspend/resume time. For this, call ahci_platform_enable/disable_phys() at suspend/resume_host() time. These calls are guarded by a HFLAG (AHCI_HFLAG_SUSPEND_PHYS) that the user of the libahci driver must set manually in hpriv->flags at probe time. This is to avoid breaking users that have not been tested with this change.

KVM/VMX: Avoid return error when flush tlb successfully in the hv_remote_flush_tlb_with_range()
The "ret" is initialized to be ENOTSUPP. The return value of
__hv_remote_flush_tlb_with_range() will be Or with "ret" when ept
table potiners are mismatched. This will cause return ENOTSUPP even if
flush tlb successfully. This patch is to fix the issue and set
"ret" to 0.

kvm: sev: Fail KVM_SEV_INIT if already initialized
By code inspection, it was found that multiple calls to KVM_SEV_INIT
could deplete asid bits and overwrite kvm_sev_info's regions_list.
Multiple calls to KVM_SVM_INIT is not likely to occur with QEMU, but this
should likely be fixed anyway.

ACPI fixes for 5.0-rc2
- Fix build failures with both CONFIG_NLS and CONFIG_PCI unset that
can occur since ACPI can be built without PCI now (Sinan Kaya).
- Clean up the handling of duplicate entries in power resource lists
returned by _PRx evaluation to avoid triggering WARN_ON() on
attempts to add duplicate symlinks in sysfs (Hans de Goede).
- Fix issues with the TS current-source switching on systems using
the xpower PMIC by avoiding to update unrelated bits in the TS
pin-ctrl register and avoiding to unconditionally enable TS
current-source on systems where it is not used (Hans de Goede).
- Fix addresses in NUMA-related messages on 32-bit with PAE which
can be truncated due to integer type conversions (Chao Fan).

tty: Don't hold ldisc lock in tty_reopen() if ldisc present
Try to get reference for ldisc during tty_reopen(). If ldisc present, we don't need to do tty_ldisc_reinit() and lock the write side for line discipline semaphore. Effectively, it optimizes fast-path for tty_reopen(), but more importantly it won't interrupt ongoing IO on the tty as no ldisc change is needed. Fixes user-visible issue when tty_reopen() interrupted login process for user with a long password, observed and reported by Lukas. Fixes: |

CIFS: Move credit processing to mid callbacks for SMB3
Currently we account for credits in the thread initiating a request and waiting for a response. The demultiplex thread receives the response, wakes up the thread and the latter collects credits from the response buffer and add them to the server structure on the client. This approach is not accurate, because it may race with reconnect events in the demultiplex thread which resets the number of credits. Fix this by moving credit processing to new mid callbacks that collect credits granted by the server from the response in the demultiplex thread.

CIFS: Fix credits calculation for cancelled requests
If a request is cancelled, we can't assume that the server returns 1 credit back. Instead we need to wait for a response and process the number of credits granted by the server. Create a separate mid callback for cancelled request, parse the number of credits in a response buffer and add them to the client's credits. If the didn't get a response (no response buffer available) assume 0 credits granted. The latter most probably happens together with session reconnect, so the client's credits are adjusted anyway.
