+Subject: amba: Fix resource leak for drivers without .remove
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+From: Uwe Kleine-König <u.kleine-koenig@pengutronix.de>
+
+[ Upstream commit de5d7adb89367bbc87b4e5ce7afe7ae9bd86dc12 ]
+
+Consider an amba driver with a .probe but without a .remove callback (e.g.
+pl061_gpio_driver). The function amba_probe() is called to bind a device
+and so dev_pm_domain_attach() and others are called. As there is no remove
+callback amba_remove() isn't called at unbind time however and so calling
+dev_pm_domain_detach() is missed and the pm domain keeps active.
+
+To fix this always use the core driver callbacks and handle missing amba
+callbacks there. For probe refuse registration as a driver without probe
+doesn't make sense.

+Subject: ARM: 9046/1: decompressor: Do not clear SCTLR.nTLSMD for ARMv7+ cores
+
+From: Vladimir Murzin <vladimir.murzin@arm.com>
+
+[ Upstream commit 2acb909750431030b65a0a2a17fd8afcbd813a84 ]
+
+It was observed that decompressor running on hardware implementing ARM v8.2
+Load/Store Multiple Atomicity and Ordering Control (LSMAOC), say, as guest,
+would stuck just after:
+
+Uncompressing Linux... done, booting the kernel.
+
+The reason is that it clears nTLSMD bit when disabling caches:
+
+  nTLSMD, bit [3]
+
+  When ARMv8.2-LSMAOC is implemented:
+
+    No Trap Load Multiple and Store Multiple to
+    Device-nGRE/Device-nGnRE/Device-nGnRnE memory.
+
+    0b0 All memory accesses by A32 and T32 Load Multiple and Store
+        Multiple at EL1 or EL0 that are marked at stage 1 as
+        Device-nGRE/Device-nGnRE/Device-nGnRnE memory are trapped and
+        generate a stage 1 Alignment fault.
+
+    0b1 All memory accesses by A32 and T32 Load Multiple and Store
+        Multiple at EL1 or EL0 that are marked at stage 1 as
+        Device-nGRE/Device-nGnRE/Device-nGnRnE memory are not trapped.
+
+  This bit is permitted to be cached in a TLB.
+
+  This field resets to 1.
+
+  Otherwise:
+
+  Reserved, RES1
+
+So as effect we start getting traps we are not quite ready for.
+
+Looking into history it seems that mask used for SCTLR clear came from
+the similar code for ARMv4, where bit[3] is the enable/disable bit for
+the write buffer. That not applicable to ARMv7 and onwards, so retire
+that bit from the masks.

+
+From: Colin Ian King <colin.king@canonical.com>
+
+[ Upstream commit 4773acf3d4b50768bf08e9e97a204819e9ea0895 ]
+
+The documentation for the PHY update [1] states:
+
+Loop 4 times with index i
+
+    If PHY Revision >= 3
+        Copy table[i] to coef[i]
+    Otherwise
+        Set coef[i] to 0
+
+the copy of the table to coef is currently implemented the wrong way
+around, table is being updated from uninitialized values in coeff.
+Fix this by swapping the assignment around.

+From: Dan Carpenter <dan.carpenter@oracle.com>
+
+[ Upstream commit 15ccc39b3aab667c6fa131206f01f31bfbccdf6a ]
+
+The main problem with this error handling was that it didn't clean up if
+i2c_add_numbered_adapter() failed.  This code is pretty old, and doesn't
+match with today's checkpatch.pl standards so I took the opportunity to
+tidy it up a bit.  I changed the NULL comparison, and removed the
+WARNING message if kzalloc() fails and updated the label names.

+Subject: HID: core: detect and skip invalid inputs to snto32()
+
+From: Randy Dunlap <rdunlap@infradead.org>
+
+[ Upstream commit a0312af1f94d13800e63a7d0a66e563582e39aec ]
+
+Prevent invalid (0, 0) inputs to hid-core's snto32() function.
+
+Maybe it is just the dummy device here that is causing this, but
+there are hundreds of calls to snto32(0, 0). Having n (bits count)
+of 0 is causing the current UBSAN trap with a shift value of
+0xffffffff (-1, or n - 1 in this function).
+
+Either of the value to shift being 0 or the bits count being 0 can be
+handled by just returning 0 to the caller, avoiding the following
+complex shift + OR operations:
+
+       return value & (1 << (n - 1)) ? value | (~0U << n) : value;

+However, if 'risc->cpu != NULL', the memory will be freed, but never
+reallocated with the bigger 'size'.
+Explicitly set 'risc->cpu' to NULL, so that the reallocation is
+correctly performed a few lines below.

+
+[ Upstream commit 59a3e78f8cc33901fe39035c1ab681374bba95ad ]
+
+There's a comma used instead of a semicolon that causes multiple
+statements to be executed after an if instead of just the intended
+single statement.
+
+Replace the comma with a semicolon.

+[ Upstream commit dc9455ffae02d7b7fb51ba1e007fffcb9dc5d890 ]
+
+The Renkforce RF AC4K 300 Action Cam 4K reports invalid bFormatIndex and
+bFrameIndex values when negotiating the video probe and commit controls.
+The UVC descriptors report a single supported format and frame size,
+with bFormatIndex and bFrameIndex both equal to 2, but the video probe
+and commit controls report bFormatIndex and bFrameIndex set to 1.
+
+The device otherwise operates correctly, but the driver rejects the
+values and fails the format try operation. Fix it by ignoring the
+invalid indices, and assuming that the format and frame requested by the
+driver are accepted by the device.

+[ Upstream commit 90a3e375d324b2255b83e3dd29e99e2b05d82aaf ]
+
+Since commit 42e4089c7890 ("x86/speculation/l1tf: Disallow non privileged

+
+ "While the fix is correct, I'm not sure if it actually is a real bug.
+  Is there any architecture that would do something else than unlocking

+
+After 34e3207205ef ("PCI: handle positive error codes"),

+Remove comparisons with PCIBIOS_SUCCESSFUL and check only for non-zero.  It
+happens that PCIBIOS_SUCCESSFUL is zero, so this is not a functional
+change, but it aligns this code with the user accessors.

+[ Upstream commit c5c97cadd7ed13381cb6b4bef5c841a66938d350 ]
+
+The ubsan reported the following error.  It was because sample's raw
+data missed u32 padding at the end.  So it broke the alignment of the
+array after it.
+
+The raw data contains an u32 size prefix so the data size should have
+an u32 padding after 8-byte aligned data.

+
+From: Nathan Lynch <nathanl@linux.ibm.com>
+
+[ Upstream commit 768d70e19ba525debd571b36e6d0ab19956c63d7 ]
+
+dlpar_configure_connector() has two problems in its handling of
+ibm,configure-connector's return status:
+
+1. When the status is -2 (busy, call again), we call
+   ibm,configure-connector again immediately without checking whether
+   to schedule, which can result in monopolizing the CPU.
+2. Extended delay status (9900..9905) goes completely unhandled,
+   causing the configuration to unnecessarily terminate.
+
+Fix both of these issues by using rtas_busy_delay().

+Subject: sparc64: only select COMPAT_BINFMT_ELF if BINFMT_ELF is set
+
+From: Randy Dunlap <rdunlap@infradead.org>
+
+[ Upstream commit 80bddf5c93a99e11fc9faf7e4b575d01cecd45d3 ]
+
+Currently COMPAT on SPARC64 selects COMPAT_BINFMT_ELF unconditionally,
+even when BINFMT_ELF is not enabled. This causes a kconfig warning.
+
+Instead, just select COMPAT_BINFMT_ELF if BINFMT_ELF is enabled.
+This builds cleanly with no kconfig warnings.
+
+WARNING: unmet direct dependencies detected for COMPAT_BINFMT_ELF
+  Depends on [n]: COMPAT [=y] && BINFMT_ELF [=n]
+  Selected by [y]:
+  - COMPAT [=y] && SPARC64 [=y]

+We need to take the mmap lock around find_vma() and subsequent use of the
+VMA. Otherwise, we can race with concurrent operations like munmap(), which

+Subject: tracepoint: Do not fail unregistering a probe due to memory failure
+
+From: Steven Rostedt (VMware) <rostedt@goodmis.org>
+
+[ Upstream commit befe6d946551d65cddbd32b9cb0170b0249fd5ed ]
+
+The list of tracepoint callbacks is managed by an array that is protected
+by RCU. To update this array, a new array is allocated, the updates are
+copied over to the new array, and then the list of functions for the
+tracepoint is switched over to the new array. After a completion of an RCU
+grace period, the old array is freed.
+
+This process happens for both adding a callback as well as removing one.
+But on removing a callback, if the new array fails to be allocated, the
+callback is not removed, and may be used after it is freed by the clients
+of the tracepoint.
+
+There's really no reason to fail if the allocation for a new array fails
+when removing a function. Instead, the function can simply be replaced by a
+stub function that could be cleaned up on the next modification of the
+array. That is, instead of calling the function registered to the
+tracepoint, it would call a stub function in its place.

+Link: https://lkml.kernel.org/r/20201118093405.7a6d2290@gandalf.local.home
+
+[ Note, this version does use undefined compiler behavior (assuming that
+  a stub function with no parameters or return, can be called by a location
+  that thinks it has parameters but still no return value. Static calls
+  do the same thing, so this trick is not without precedent.
+
+  There's another solution that uses RCU tricks and is more complex, but
+  can be an alternative if this solution becomes an issue.

+dwc2 ff540000.usb: dwc2_hc_chhltd_intr_dma: Channel 1 - ChHltd set, but reason is unknown
+dwc2 ff540000.usb: hcint 0x00000002, intsts 0x04000021
+
+This is sometimes followed by:
+
+dwc2 ff540000.usb: dwc2_update_urb_state_abn(): trimming xfer length
+
+and then:
+
+WARNING: CPU: 0 PID: 0 at kernel/v4.19/drivers/usb/dwc2/hcd.c:2913
+                       dwc2_assign_and_init_hc+0x98c/0x990
+
+The warning suggests that an odd buffer address is to be used for DMA.
+
+After an error is observed, the receive buffer may be full
+(urb->actual_length >= urb->length). However, the urb is still left in
+the queue unless three errors were observed in a row. When it is queued
+again, the dwc2 hcd code translates this into a 1-block transfer.
+If urb->actual_length (ie the total expected receive length) is not
+DMA-aligned, the buffer pointer programmed into the chip will be
+unaligned. This results in the observed warning.
+
+To solve the problem, abort input transactions after an error with
+unknown cause if the entire packet was already received. This may be
+a bit drastic, but we don't really know why the transfer was aborted
+even though the entire packet was received. Aborting the transfer in
+this situation is less risky than accepting a potentially corrupted
+packet.
+
+With this patch in place, the 'ChHltd set' and 'trimming xfer length'
+messages are still observed, but there are no more transfer attempts
+with odd buffer addresses.

+Subject: usb: dwc2: Make "trimming xfer length" a debug message
+
+From: Guenter Roeck <linux@roeck-us.net>
+
+[ Upstream commit 1a9e38cabd80356ffb98c2c88fec528ea9644fd5 ]
+
+With some USB network adapters, such as DM96xx, the following message
+is seen for each maximum size receive packet.
+
+dwc2 ff540000.usb: dwc2_update_urb_state(): trimming xfer length
+
+This happens because the packet size requested by the driver is 1522
+bytes, wMaxPacketSize is 64, the dwc2 driver configures the chip to
+receive 24*64 = 1536 bytes, and the chip does indeed send more than
+1522 bytes of data. Since the event does not indicate an error condition,
+the message is just noise. Demote it to debug level.

+Subject: VMCI: Use set_page_dirty_lock() when unregistering guest memory
+
+From: Jorgen Hansen <jhansen@vmware.com>
+
+[ Upstream commit 5a16c535409f8dcb7568e20737309e3027ae3e49 ]
+
+When the VMCI host support releases guest memory in the case where
+the VM was killed, the pinned guest pages aren't locked. Use
+set_page_dirty_lock() instead of set_page_dirty().
+
+Testing done: Killed VM while having an active VMCI based vSocket
+connection and observed warning from ext4. With this fix, no
+warning was observed. Ran various vSocket tests without issues.

+
+From: Juergen Gross <jgross@suse.com>
+
+[ Upstream commit a3daf3d39132b405781be8d9ede0c449b244b64e ]
+
+In case of a common event for rx and tx queue the event should be
+regarded to be spurious if no rx and no tx requests are pending.
+
+Unfortunately the condition for testing that is wrong causing to
+decide a event being spurious if no rx OR no tx requests are
+pending.
+
+Fix that plus using local variables for rx/tx pending indicators in
+order to split function calls and if condition.
