lib/raid6: add option to skip algo benchmarking
This is helpful for systems where fast startup time is important.
It is especially nice to avoid benchmarking RAID functions that are
never used (for example, BTRFS selects RAID6_PQ even if the parity RAID
mode is not in use).
This saves 250+ milliseconds of boot time on modern x86 and ARM systems
with a dozen or more available implementations.
The new option is defaulted to 'y' to match the previous behavior of
always benchmarking on init.

arm64: alternatives: use tpidr_el2 on VHE hosts
When upstream
6d99b68933fb was back-ported to upstream v4.9.x stable as
eea59020a7f2, the edits to arch/arm64/mm/proc.S were dropped because
proc.S didn't save/restore tpidr_el1 at all. Separately, in android-4.9,
0ec37136b90e ("UPSTREAM: arm64: move sp_el0 and tpidr_el1 into
cpu_suspend_ctx") modified proc.S to save/restore tpidir_el1. These two
paths were later merged together in android-4.9. The missing edits to
proc.S should have been added in during the merge, but were not. This
change restores those edits. The original upstream change description
of
6d99b68933fb follows; this is where the missing code appeared
originally.
Commit
6d99b68933fbcf51f84fcbba49246ce1209ec193 upstream.
Now that KVM uses tpidr_el2 in the same way as Linux's cpu_offset in
tpidr_el1, merge the two. This saves KVM from save/restoring tpidr_el1
on VHE hosts, and allows future code to blindly access per-cpu variables
without triggering world-switch.

arm64: relocatable: fix inconsistencies in linker script and options
commit
3bbd3db86470c701091fb1d67f1fab6621debf50 upstream.
readelf complains about the section layout of vmlinux when building
with CONFIG_RELOCATABLE=y (for KASLR):
readelf: Warning: [21]: Link field (0) should index a symtab section.
readelf: Warning: [21]: Info field (0) should index a relocatable section.
Also, it seems that our use of '-pie -shared' is contradictory, and
thus ambiguous. In general, the way KASLR is wired up at the moment
is highly tailored to how ld.bfd happens to implement (and conflate)
PIE executables and shared libraries, so given the current effort to
support other toolchains, let's fix some of these issues as well.
- Drop the -pie linker argument and just leave -shared. In ld.bfd,
the differences between them are unclear (except for the ELF type
of the produced image [0]) but lld chokes on seeing both at the
same time.
- Rename the .rela output section to .rela.dyn, as is customary for
shared libraries and PIE executables, so that it is not misidentified
by readelf as a static relocation section (producing the warnings
above).
- Pass the -z notext and -z norelro options to explicitly instruct the
linker to permit text relocations, and to omit the RELRO program
header (which requires a certain section layout that we don't adhere
to in the kernel). These are the defaults for current versions of
ld.bfd.
- Discard .eh_frame and .gnu.hash sections to avoid them from being
emitted between .head.text and .text, screwing up the section layout.
These changes only affect the ELF image, and produce the same binary
image.

Smack: ignore private inode for file functions
The access to fd from anon_inode is always failed because there is
no set xattr operations. So this patch fixes to ignore private
inode including anon_inode for file functions.
It was only ignored for smack_file_receive() to share dma-buf fd,
but dma-buf has other functions like ioctl and mmap.

Smack: fix d_instantiate logic for sockfs and pipefs
Since
4b936885a (v2.6.32) all inodes on sockfs and pipefs are disconnected.
It caused filesystem specific code in smack_d_instantiate to be skipped,
because all inodes on those pseudo filesystems were treated as root inodes.
As a result all sockfs inodes had the Smack label set to floor.
In most cases access checks for sockets use socket_smack data so the inode
label is not important. But there are special cases that were broken.
One example would be calling fcntl with F_SETOWN command on a socket fd.
Now smack_d_instantiate expects all pipefs and sockfs inodes to be
disconnected and has the logic in appropriate place.

arm64: Silence gcc warnings about arch ABI drift
Since GCC 9, the compiler warns about evolution of the
platform-specific ABI, in particular relating for the marshaling of
certain structures involving bitfields.
The kernel is a standalone binary, and of course nobody would be
so stupid as to expose structs containing bitfields as function
arguments in ABI. (Passing a pointer to such a struct, however
inadvisable, should be unaffected by this change. perf and various
drivers rely on that.)
So these warnings do more harm than good: turn them off.
We may miss warnings about future ABI drift, but that's too bad.
Future ABI breaks of this class will have to be debugged and fixed
the traditional way unless the compiler evolves finer-grained
diagnostics.

USB: cdc-wdm: Make wdm_flush() interruptible and add wdm_fsync().
commit
37d2a36394d954413a495da61da1b2a51ecd28ab upstream.
syzbot is reporting hung task at wdm_flush() [1], for there is a circular
dependency that wdm_flush() from flip_close() for /dev/cdc-wdm0 forever
waits for /dev/raw-gadget to be closed while close() for /dev/raw-gadget
cannot be called unless close() for /dev/cdc-wdm0 completes.
Tetsuo Handa considered that such circular dependency is an usage error [2]
which corresponds to an unresponding broken hardware [3]. But Alan Stern
responded that we should be prepared for such hardware [4]. Therefore,
this patch changes wdm_flush() to use wait_event_interruptible_timeout()
which gives up after 30 seconds, for hardware that remains silent must be
ignored. The 30 seconds are coming out of thin air.
Changing wait_event() to wait_event_interruptible_timeout() makes error
reporting from close() syscall less reliable. To compensate it, this patch
also implements wdm_fsync() which does not use timeout. Those who want to
be very sure that data has gone out to the device are now advised to call
fsync(), with a caveat that fsync() can return -EINVAL when running on
older kernels which do not implement wdm_fsync().
This patch also fixes three more problems (listed below) found during
exhaustive discussion and testing.
Since multiple threads can concurrently call wdm_write()/wdm_flush(),
we need to use wake_up_all() whenever clearing WDM_IN_USE in order to
make sure that all waiters are woken up. Also, error reporting needs
to use fetch-and-clear approach in order not to report same error for
multiple times.
Since wdm_flush() checks WDM_DISCONNECTING, wdm_write() should as well
check WDM_DISCONNECTING.
In wdm_flush(), since locks are not held, it is not safe to dereference
desc->intf after checking that WDM_DISCONNECTING is not set [5]. Thus,
remove dev_err() from wdm_flush().

Thus, these have been added to the ignore list in

[ Upstream commit
bad60b8d1a7194df38fd7fe4b22f3f4dcf775099 ]
The idx in __ath10k_htt_rx_ring_fill_n function lives in
consistent dma region writable by the device. Malfunctional
or malicious device could manipulate such idx to have a OOB
write. Either by
htt->rx_ring.netbufs_ring[idx] = skb;
or by
ath10k_htt_set_paddrs_ring(htt, paddr, idx);
The idx can also be negative as it's signed, giving a large
memory space to write to.
It's possibly exploitable by corruptting a legit pointer with
a skb pointer. And then fill skb with payload as rougue object.
Part of the log here. Sometimes it appears as UAF when writing
to a freed memory by chance.

usb: core: Solve race condition in anchor cleanup functions
[ Upstream commit
fbc299437c06648afcc7891e6e2e6638dd48d4df ]
usb_kill_anchored_urbs() is commonly used to cancel all URBs on an
anchor just before releasing resources which the URBs rely on. By doing
so, users of this function rely on that no completer callbacks will take
place from any URB on the anchor after it returns.
However if this function is called in parallel with __usb_hcd_giveback_urb
processing a URB on the anchor, the latter may call the completer
callback after usb_kill_anchored_urbs() returns. This can lead to a
kernel panic due to use after release of memory in interrupt context.
The race condition is that __usb_hcd_giveback_urb() first unanchors the URB
and then makes the completer callback. Such URB is hence invisible to
usb_kill_anchored_urbs(), allowing it to return before the completer has
been called, since the anchor's urb_list is empty.
Even worse, if the racing completer callback resubmits the URB, it may
remain in the system long after usb_kill_anchored_urbs() returns.
Hence list_empty(&anchor->urb_list), which is used in the existing
while-loop, doesn't reliably ensure that all URBs of the anchor are gone.
A similar problem exists with usb_poison_anchored_urbs() and
usb_scuttle_anchored_urbs().
This patch adds an external do-while loop, which ensures that all URBs
are indeed handled before these three functions return. This change has
no effect at all unless the race condition occurs, in which case the
loop will busy-wait until the racing completer callback has finished.
This is a rare condition, so the CPU waste of this spinning is
negligible.
The additional do-while loop relies on usb_anchor_check_wakeup(), which
returns true iff the anchor list is empty, and there is no
__usb_hcd_giveback_urb() in the system that is in the middle of the
unanchor-before-complete phase. The @suspend_wakeups member of
struct usb_anchor is used for this purpose, which was introduced to solve
another problem which the same race condition causes, in commit
6ec4147e7bdb ("usb-anchor: Delay usb_wait_anchor_empty_timeout wake up
till completion is done").
The surely_empty variable is necessary, because usb_anchor_check_wakeup()
must be called with the lock held to prevent races. However the spinlock
must be released and reacquired if the outer loop spins with an empty
URB list while waiting for the unanchor-before-complete passage to finish:
The completer callback may very well attempt to take the very same lock.
To summarize, using usb_anchor_check_wakeup() means that the patched
functions can return only when the anchor's list is empty, and there is
no invisible URB being processed. Since the inner while loop finishes on
the empty list condition, the new do-while loop will terminate as well,
except for when the said race condition occurs.

Bluetooth: Only mark socket zapped after unlocking

Since l2cap_sock_teardown_cb doesn't acquire the channel lock before

l2cap_sock_release which frees the socket. Thus, wait until the cleanup

usb: ohci: Default to per-port over-current protection
[ Upstream commit
b77d2a0a223bc139ee8904991b2922d215d02636 ]
Some integrated OHCI controller hubs do not expose all ports of the hub
to pins on the SoC. In some cases the unconnected ports generate
spurious over-current events. For example the Broadcom 56060/Ranger 2 SoC
contains a nominally 3 port hub but only the first port is wired.
Default behaviour for ohci-platform driver is to use global over-current
protection mode (AKA "ganged"). This leads to the spurious over-current
events affecting all ports in the hub.
We now alter the default to use per-port over-current protection.
This patch results in the following configuration changes depending
on quirks:
- For quirk OHCI_QUIRK_SUPERIO no changes. These systems remain set up
for ganged power switching and no over-current protection.
- For quirk OHCI_QUIRK_AMD756 or OHCI_QUIRK_HUB_POWER power switching
remains at none, while over-current protection is now guaranteed to be
set to per-port rather than the previous behaviour where it was either
none or global over-current protection depending on the value at
function entry.

xfs: make sure the rt allocator doesn't run off the end

There's an overflow bug in the realtime allocator. If the rt volume is
large enough to handle a single allocation request that is larger than
the maximum bmap extent length and the rt bitmap ends exactly on a
bitmap block boundary, it's possible that the near allocator will try to
check the freeness of a range that extends past the end of the bitmap.
This fails with a corruption error and shuts down the fs.
Therefore, constrain maxlen so that the range scan cannot run off the
end of the rt bitmap.

reiserfs: only call unlock_new_inode() if I_NEW
[ Upstream commit
8859bf2b1278d064a139e3031451524a49a56bd0 ]
unlock_new_inode() is only meant to be called after a new inode has
already been inserted into the hash table. But reiserfs_new_inode() can
call it even before it has inserted the inode, triggering the WARNING in
unlock_new_inode(). Fix this by only calling unlock_new_inode() if the
inode has the I_NEW flag set, indicating that it's in the table.
This addresses the syzbot report "WARNING in unlock_new_inode"
(https://syzkaller.appspot.com/bug?extid=
187510916eb6a14598f7).

When mfd_add_devices() fail, pcr->slots should also be freed. However,
the current implementation does not free the member, leading to a memory

Fix this by adding a new goto label that frees pcr->slots.

ath9k: hif_usb: fix race condition between usb_get_urb() and usb_kill_anchored_urbs()
[ Upstream commit
03fb92a432ea5abe5909bca1455b7e44a9380480 ]
Calls to usb_kill_anchored_urbs() after usb_kill_urb() on multiprocessor
systems create a race condition in which usb_kill_anchored_urbs() deallocates
the URB before the completer callback is called in usb_kill_urb(), resulting
in a use-after-free.
To fix this, add proper lock protection to usb_kill_urb() calls that can
possibly run concurrently with usb_kill_anchored_urbs().

USB: cdc-acm: handle broken union descriptors
[ Upstream commit

Handle broken union functional descriptors where the master-interface
doesn't exist or where its class is of neither Communication or Data
type (as required by the specification) by falling back to
"combined-interface" probing.
Note that this still allows for handling union descriptors with switched
interfaces.
This specifically makes the Whistler radio scanners TRX series devices
work with the driver without adding further quirks to the device-id
table.

misc: vop: add round_up(x,4) for vring_size to avoid kernel panic
[ Upstream commit
cc1a2679865a94b83804822996eed010a50a7c1d ]
Since struct _mic_vring_info and vring are allocated together and follow
vring, if the vring_size() is not four bytes aligned, which will cause
the start address of struct _mic_vring_info is not four byte aligned.
For example, when vring entries is 128, the vring_size() will be 5126
bytes. The _mic_vring_info struct layout in ddr looks like:
0x90002400:
00000000 00390000 EE010000 0000C0FF
Here 0x39 is the avail_idx member, and 0xC0FFEE01 is the magic member.
When EP use ioread32(magic) to reads the magic in RC's share memory, it
will cause kernel panic on ARM64 platform due to the cross-byte io read.
Here read magic in user space use le32toh(vr0->info->magic) will meet
the same issue.
So add round_up(x,4) for vring_size, then the struct _mic_vring_info
will store in this way:
0x90002400:
00000000 00000000 00000039 C0FFEE01
Which will avoid kernel panic when read magic in struct _mic_vring_info.
