+Syzkaller detected a use-after-free issue in ext4_insert_dentry that was
+caused by out-of-bounds access due to incorrect splitting in do_split.

+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+From: Niklas Söderlund <niklas.soderlund+renesas@ragnatech.se>
+
+commit 9e38acacb9d809b97a0bdc5c76e725355a47158a upstream.
+
+The mask to select the test-pattern in register ADV748X_SDP_FRP is
+incorrect, it's the lower 3 bits which controls the pattern. The
+GENMASK() macro is used incorrectly and the generated mask is 0x0e
+instead of 0x07.
+
+The result is that not all test patterns are selectable, and that in
+some cases the wrong test pattern is activated. Fix this by correcting
+the GENMASK().

+
+commit 549f6d348167fb2f7800ed7c8d4bce9630c74498 upstream.
+
+If streamzap_callback() receives an urb with any non-critical error
+status, i.e. any error code other than -ECONNRESET, -ENOENT or -ESHUTDOWN,
+it will try to process IR data, ignoring a possible transfer failure.
+
+Make streamzap_callback() process IR data only when urb->status is 0.
+Move processing logic to a separate function to make code cleaner and
+more similar to the URB completion handlers in other RC drivers.

+
+commit 3edd1fc48d2c045e8259561797c89fe78f01717e upstream.
+
+In v4l2_detect_gtf(), it seems safer to cast the 32-bit image_width
+variable to the 64-bit type u64 before multiplying to avoid
+a possible overflow. The resulting object code even seems to
+look better, at least on x86_64.

+Subject: media: venus: hfi: add check to handle incorrect queue size
+
+From: Vikash Garodia <quic_vgarodia@quicinc.com>
+
+commit 69baf245b23e20efda0079238b27fc63ecf13de1 upstream.
+
+qsize represents size of shared queued between driver and video
+firmware. Firmware can modify this value to an invalid large value. In
+such situation, empty_space will be bigger than the space actually
+available. Since new_wr_idx is not checked, so the following code will
+result in an OOB write.
+...
+qsize = qhdr->q_size
+
+if (wr_idx >= rd_idx)
+ empty_space = qsize - (wr_idx - rd_idx)
+....
+if (new_wr_idx < qsize) {
+ memcpy(wr_ptr, packet, dwords << 2) --> OOB write
+
+Add check to ensure qsize is within the allocated size while
+reading and writing packets into the queue.

+
+From: Vikash Garodia <quic_vgarodia@quicinc.com>
+
+commit 172bf5a9ef70a399bb227809db78442dc01d9e48 upstream.
+
+There is a possibility that init_codecs is invoked multiple times during
+manipulated payload from video firmware. In such case, if codecs_count
+can get incremented to value more than MAX_CODEC_NUM, there can be OOB
+access. Reset the count so that it always starts from beginning.

+
+The fix uses the higher level nand_reset(chip, chipnr); where chipnr = 0, when
+doing PM resume operation in compliance with the controller support for single
+die nand chip. Switching from nand_reset_op() to nand_reset() implies more
+than just setting the cs field op->cs, it also reconfigures the data interface
+(ie. the timings). Tested and confirmed the NAND chip is in sync timing wise
+with host after the fix.

+
+Implement the workaround for erratum
+ 3.3 RGMII timing may be out of spec when transmit delay is enabled
+for the 6320 family, which says:
+
+ When transmit delay is enabled via Port register 1 bit 14 = 1, duty
+ cycle may be out of spec. Under very rare conditions this may cause
+ the attached device receive CRC errors.

+
+commit d00c0c4105e5ab8a6a13ed23d701cceb285761fa upstream.
+
+Since the new_metric and last_hop_metric variables can reach
+the MAX_METRIC(0xffffffff) value, an integer overflow may occur
+when multiplying them by 10/9. It can lead to incorrect behavior.
+
+Found by InfoTeCS on behalf of Linux Verification Center

+The interface specifies the symnum field as an input and output; the
+hypervisor sets it to the next sequential symbol's index. xensyms_next()
+incrementing the position explicitly (and xensyms_next_sym()
+decrementing it to "rewind") is only correct as long as the sequence of
+symbol indexes is non-sparse. Use the hypervisor-supplied value instead
+to update the position in xensyms_next(), and use the saved incoming
+index in xensyms_next_sym().
