Every time _cpu_up() is called for a CPU, idle_thread_get() is called
which then re-initializes a CPU's idle thread that was already
previously created and cached in a global variable in
smpboot.c. idle_thread_get() calls init_idle() which then calls
__sched_fork(). __sched_fork() is where cpufreq_task_times_init() is,
and cpufreq_task_times_init() allocates memory for the task struct's
time_in_state array.
Since idle_thread_get() reuses a task struct instance that was already
previously created, this means that every time it calls init_idle(),
cpufreq_task_times_init() allocates this array again and overwrites
the existing allocation that the idle thread already had.
This causes memory to be leaked every time a CPU is onlined. In order
to fix this, move allocation of time_in_state into _do_fork to avoid
allocating it at all for idle threads. The cpufreq times interface is
intended to be used for tracking userspace tasks, so we can safely
remove it from the kernel's idle threads without killing any
functionality.
But that's not all!
Task structs can be freed outside of release_task(), which creates
another memory leak because a task struct can be freed without having
its cpufreq times allocation freed. To fix this, free the cpufreq
times allocation at the same time that task struct allocations are
freed, in free_task().
Since free_task() can also be called in error paths of copy_process()
after dup_task_struct(), set time_in_state to NULL immediately after
calling dup_task_struct() to avoid possible double free.

commit d3349b6b3c373ac1fbfb040b810fcee5e2adc7e0 upstream.
syzbot is hitting WARN() triggered by memory allocation fault
injection [1] because loop module is calling sysfs_remove_group()
when sysfs_create_group() failed.
Fix this by remembering whether sysfs_create_group() succeeded.

commit 7a8690ed6f5346f6738971892205e91d39b6b901 upstream.
In commit 357d23c811a7 ("Remove the obsolete libibcm library")
in rdma-core [1], we removed obsolete library which used the
/dev/infiniband/ucmX interface.
Following multiple syzkaller reports about non-sanitized
user input in the UCMA module, the short audit reveals the same
issues in UCM module too.
It is better to disable this interface in the kernel,
before syzkaller team invests time and energy to harden
this unused interface.

commit fc14eebfc20854a38fd9f1d93a42b1783dad4d17 upstream.
syzbot is reporting NULL pointer dereference at snapshot_write() [1].
This is because data->handle is zero-cleared by ioctl(SNAPSHOT_FREE).
Fix this by checking data_of(data->handle) != NULL before using it.

commit d2ac838e4cd7e5e9891ecc094d626734b0245c99 upstream.
Refactor the validation code used in LOOP_SET_FD so it is also used in
LOOP_CHANGE_FD. Otherwise it is possible to construct a set of loop
devices that all refer to each other. This can lead to a infinite
loop in starting with "while (is_loop_device(f)) .." in loop_set_fd().
Fix this by refactoring out the validation code and using it for
LOOP_CHANGE_FD as well as LOOP_SET_FD.

commit 815c6704bf9f1c59f3a6be380a4032b9c57b12f1 upstream.
The controller memory buffer is remapped into a kernel address on each
reset, but the driver was setting the submission queue base address
only on the very first queue creation. The remapped address is likely to
change after a reset, so accessing the old address will hit a kernel bug.
This patch fixes that by setting the queue's CMB base address each time
the queue is created.

commit 54836e2d03e76d80aec3399368ffaf5b7caadd1b upstream.
On Tegra30 Cardhu the PCA9546 I2C mux is not ACK'ing I2C commands on
resume from suspend (which is caused by the reset signal for the I2C
mux not being configured correctl). However, this NACK is causing the
Tegra30 to hang on resuming from suspend which is not expected as we
detect NACKs and handle them. The hang observed appears to occur when
resetting the I2C controller to recover from the NACK.
Commit 77821b4678f9 ("i2c: tegra: proper handling of error cases") added
additional error handling for some error cases including NACK, however,
it appears that this change conflicts with an early fix by commit
f70893d08338 ("i2c: tegra: Add delay before resetting the controller
after NACK"). After commit 77821b4678f9 was made we now disable 'packet
mode' before the delay from commit f70893d08338 happens. Testing shows
that moving the delay to before disabling 'packet mode' fixes the hang
observed on Tegra30. The delay was added to give the I2C controller
chance to send a stop condition and so it makes sense to move this to
before we disable packet mode. Please note that packet mode is always
enabled for Tegra.

commit 9feeb638cde083c737e295c0547f1b4f28e99583 upstream.
In 2016 GNU Make made a backwards incompatible change to the way '#'
characters were handled in Makefiles when used inside functions or
macros:
http://git.savannah.gnu.org/cgit/make.git/commit/?id=c6966b323811c37acedff05b57
Due to this change, when attempting to run `make prepare' I get a
spurious make syntax error:
/home/earnest/linux/tools/objtool/.fixdep.o.cmd:1: *** missing separator. Stop.
When inspecting `.fixdep.o.cmd' it includes two lines which use
unescaped comment characters at the top:
\# cannot find fixdep (/home/earnest/linux/tools/objtool//fixdep)
\# using basic dep data
This is because `tools/build/Build.include' prints these '\#'
characters:
printf '\# cannot find fixdep (%s)\n' $(fixdep) > $(dot-target).cmd; \
printf '\# using basic dep data\n\n' >> $(dot-target).cmd; \
This completes commit 9564a8cf422d ("Kbuild: fix # escaping in .cmd files
for future Make").

commit aaa23f86001bdb82d2f937c5c7bce0a1e11a6c5b upstream.
Obtaining the runtime pm wakeref can fail, especially in a hotplug
scenario where i915.ko has been unloaded. If we do not catch the
failure, we end up with an unbalanced pm.
v2 additions by tiwai:
hdmi_present_sense() checks the return value and handle only a
negative error case and bails out only if it's really still suspended.
Also, snd_hda_power_down() is called at the error path so that the
refcount is balanced.
Along with it, the spec->pcm_lock is taken outside
hdmi_present_sense() in the caller side, so that it won't cause
deadlock at reentrace via runtime resume.
v3 fix by tiwai:
Missing linux/pm_runtime.h is included.

commit 0fa3ecd87848c9c93c2c828ef4c3a8ca36ce46c7 upstream.
sgid directories have special semantics, making newly created files in
the directory belong to the group of the directory, and newly created
subdirectories will also become sgid. This is historically used for
group-shared directories.
But group directories writable by non-group members should not imply
that such non-group members can magically join the group, so make sure
to clear the sgid bit on non-directories for non-members (but remember
that sgid without group execute means "mandatory locking", just to
confuse things even more).

commit bba57eddadda936c94b5dccf73787cb9e159d0a5 upstream.
Corsair Strafe appears to suffer from the same issues
as the Corsair Strafe RGB.
Apply the same quirks (control message delay and init delay)
that the RGB version has to 1b1c:1b15.
With these quirks in place the keyboard works correctly upon
booting the system, and no longer requires reattaching the device.

commit f1e255d60ae66a9f672ff9a207ee6cd8e33d2679 upstream.
In general, accessing userspace memory beyond the length of the supplied
buffer in VFS read/write handlers can lead to both kernel memory corruption
(via kernel_read()/kernel_write(), which can e.g. be triggered via
sys_splice()) and privilege escalation inside userspace.
Fix it by using simple_read_from_buffer() instead of custom logic.

commit 240630e61870e62e39a97225048f9945848fa5f5 upstream.
There have been several reports of LPM related hard freezes about once
a day on multiple Lenovo 50 series models. Strange enough these reports
where not disk model specific as LPM issues usually are and some users
with the exact same disk + laptop where seeing them while other users
where not seeing these issues.
It turns out that enabling LPM triggers a firmware bug somewhere, which
has been fixed in later BIOS versions.
This commit adds a new ahci_broken_lpm() function and a new ATA_FLAG_NO_LPM
for dealing with this.
The ahci_broken_lpm() function contains DMI match info for the 4 models
which are known to be affected by this and the DMI BIOS date field for
known good BIOS versions. If the BIOS date is older then the one in the
table LPM will be disabled and a warning will be printed.
Note the BIOS dates are for known good versions, some older versions may
work too, but we don't know for sure, the table is using dates from BIOS
versions for which users have confirmed that upgrading to that version
makes the problem go away.
Unfortunately I've been unable to get hold of the reporter who reported
that BIOS version 2.35 fixed the problems on the W541 for him. I've been
able to verify the DMI_SYS_VENDOR and DMI_PRODUCT_VERSION from an older
dmidecode, but I don't know the exact BIOS date as reported in the DMI.
Lenovo keeps a changelog with dates in their release notes, but the
dates there are the release dates not the build dates which are in DMI.
So I've chosen to set the date to which we compare to one day past the
release date of the 2.34 BIOS. I plan to fix this with a follow up
commit once I've the necessary info.

commit 523402fa9101090c91d2033b7ebdfdcf65880488 upstream.
We currently attempt to check whether a physical address range provided
to __ioremap() may be in use by the page allocator by examining the
value of PageReserved for each page in the region - lowmem pages not
marked reserved are presumed to be in use by the page allocator, and
requests to ioremap them fail.
The way we check this has been broken since commit 92923ca3aace ("mm:
meminit: only set page reserved in the memblock region"), because
memblock will typically not have any knowledge of non-RAM pages and
therefore those pages will not have the PageReserved flag set. Thus when
we attempt to ioremap a region outside of RAM we incorrectly fail
believing that the region is RAM that may be in use.
In most cases ioremap() on MIPS will take a fast-path to use the
unmapped kseg1 or xkphys virtual address spaces and never hit this path,
so the only way to hit it is for a MIPS32 system to attempt to ioremap()
an address range in lowmem with flags other than _CACHE_UNCACHED.
Perhaps the most straightforward way to do this is using
ioremap_uncached_accelerated(), which is how the problem was discovered.
Fix this by making use of walk_system_ram_range() to test the address
range provided to __ioremap() against only RAM pages, rather than all
lowmem pages. This means that if we have a lowmem I/O region, which is
very common for MIPS systems, we're free to ioremap() address ranges
within it. A nice bonus is that the test is no longer limited to lowmem.
The approach here matches the way x86 performed the same test after
commit c81c8a1eeede ("x86, ioremap: Speed up check for RAM pages") until
x86 moved towards a slightly more complicated check using walk_mem_res()
for unrelated reasons with commit 0e4c12b45aa8 ("x86/mm, resource: Use
PAGE_KERNEL protection for ioremap of memory pages").

commit 5a267832c2ec47b2dad0fdb291a96bb5b8869315 upstream.
The generic nmi_cpu_backtrace() function calls show_regs() when a struct
pt_regs is available, and dump_stack() otherwise. If we were to make use
of the generic nmi_cpu_backtrace() with MIPS' current implementation of
show_regs() this would mean that we see only register data with no
accompanying stack information, in contrast with our current
implementation which calls dump_stack() regardless of whether register
state is available.
In preparation for making use of the generic nmi_cpu_backtrace() to
implement arch_trigger_cpumask_backtrace(), have our implementation of
show_regs() call dump_stack() and drop the explicit dump_stack() call in
arch_dump_stack() which is invoked by arch_trigger_cpumask_backtrace().
This will allow the output we produce to remain the same after a later
patch switches to using nmi_cpu_backtrace(). It may mean that we produce
extra stack output in other uses of show_regs(), but this:
1) Seems harmless.
2) Is good for consistency between arch_trigger_cpumask_backtrace()
and other users of show_regs().
3) Matches the behaviour of the ARM & PowerPC architectures.
Marked for stable back to v4.9 as a prerequisite of the following patch
"MIPS: Call dump_stack() from show_regs()".

commit 7dd1ab163c17e11473a65b11f7e748db30618ebb upstream.
With a misbehaving controller it's possible we'll never
enter the live state and create an admin queue. When we
fail out of reset work it's possible we failed out early
enough without setting up the admin queue. We tear down
queues after a failed reset, but needed to do some more
sanitization.

proc->files cleanup is initiated by binder_vma_close. Therefore
a reference on the binder_proc is not enough to prevent the
files_struct from being released while the binder_proc still has
a reference. This can lead to an attempt to dereference the
stale pointer obtained from proc->files prior to proc->files
cleanup. This has been seen once in task_get_unused_fd_flags()
when __alloc_fd() is called with a stale "files".
The fix is to protect proc->files with a mutex to prevent cleanup
while in use.

binder_update_page_range needs down_write of mmap_sem because
vm_insert_page need to change vma->vm_flags to VM_MIXEDMAP unless
it is set. However, when I profile binder working, it seems
every binder buffers should be mapped in advance by binder_mmap.
It means we could set VM_MIXEDMAP in binder_mmap time which is
already hold a mmap_sem as down_write so binder_update_page_range
doesn't need to hold a mmap_sem as down_write.
Please use proper API down_read. It would help mmap_sem contention
problem as well as fixing down_write abuse.

New devices launching with Android P need to use the 64-bit
binder interface, even on 32-bit SoCs [0].
This change removes the Kconfig option to select the 32-bit
binder interface. We don't think this will affect existing
userspace for the following reasons:
1) The latest Android common tree is 4.14, so we don't
believe any Android devices are on kernels >4.14.
2) Android devices launch on an LTS release and stick with
it, so we wouldn't expect devices running on <= 4.14 now
to upgrade to 4.17 or later. But even if they did, they'd
rebuild the world (kernel + userspace) anyway.
3) Other userspaces like 'anbox' are already using the
64-bit interface.
Note that this change doesn't remove the 32-bit UAPI
itself; the reason for that is that Android userspace
always uses the latest UAPI headers from upstream, and
userspace retains 32-bit support for devices that are
upgrading. This will be removed as well in 2-3 years,
at which point we can remove the code from the UAPI
as well.
Finally, this change introduces build errors on archs where
64-bit get_user/put_user is not supported, so make binder
unavailable on m68k (which wouldn't want it anyway).

It doesn't make any difference to runtime but I've switched these two
checks to make my static checker happy.
The problem is that "buffer->data_size" is user controlled and if it's
less than "sizeo(*hdr)" then that means "offset" can be more than
"buffer->data_size". It's just cleaner to check it in the other order.

VM_IOREMAP is used to access hardware through a mechanism called
I/O mapped memory. Android binder is a IPC machanism which will
not access I/O memory.
And VM_IOREMAP has alignment requiement which may not needed in
binder.
__get_vm_area_node()
{
...
if (flags & VM_IOREMAP)
align = 1ul << clamp_t(int, fls_long(size),
PAGE_SHIFT, IOREMAP_MAX_ORDER);
...
}
This patch will save some kernel vm area, especially for 32bit os.
In 32bit OS, kernel vm area is only 240MB. We may got below
error when launching a app:
<3>[ 4482.440053] binder_alloc: binder_alloc_mmap_handler: 15728 8ce67000-8cf65000 get_vm_area failed -12

checkpatch warns against the use of symbolic permissions,
this patch migrates all symbolic permissions in the binder
driver to octal permissions.
Test: debugfs nodes created by binder have the same unix
permissions prior to and after this patch was applied.
