commit 5efe5137 upstream. There are some backward incompatible features pending for months, mainly due to on-disk format expensions. However, we should ensure that it cannot be mounted with old kernels. Otherwise, it will causes unexpected behaviors.

commit a370003c upstream. There is a race between the binder driver cleaning up a completed transaction via binder_free_transaction() and a user calling binder_ioctl(BC_FREE_BUFFER) to release a buffer. It doesn't matter which is first but they need to be protected against running concurrently which can result in a UAF. Signed-off-by:

commit 475df5d0 upstream. We're now calling intel_pipe_config_compare(..., true) uncoditionally which means we're always going clobber the calculated M/N values with the old values if the fuzzy M/N check passes. That causes problems because the fuzzy check allows for a huge difference in the values. I'm actually tempted to just make the M/N checks exact, but that might prevent fastboot from kicking in when people want it. So for now let's overwrite the computed values with the old values only if decide to skip the modeset. v2: Copy has_drrs along with M/N M2/N2 values Cc: stable@vger.kernel.org Cc: Blubberbub@protonmail.com Cc: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> Cc: Hans de Goede <hdegoede@redhat.com> Tested-by: Blubberbub@protonmail.com Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=110782 Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=110675 Fixes: d19f958d ("drm/i915: Enable fastset for non-boot modesets.")

commit 88a74841 upstream. If UHS speed modes are enabled, a compatible SD card switches down to 1.8V during enumeration. If after this a software reboot/crash takes place and on-chip ROM tries to enumerate the SD card, the difference in IO voltages (host @ 3.3V and card @ 1.8V) may end up damaging the card. The fix for this is to have support for power cycling the card in hardware (with a PORz/soft-reset line causing a power cycle of the card). Since am571x-, am572x- and am574x-idk don't have this capability, disable voltage switching for these boards. The major effect of this is that the maximum supported speed mode is now high speed(50 MHz) down from SDR104(200 MHz). Cc: <stable@vger.kernel.org> Signed-off-by:

commit b25af2ff upstream. Since commit 1e434b70 ("ARM: imx: update the cpu power up timing setting on i.mx6sx") some characters loss is noticed on i.MX6ULL UART as reported by Christoph Niedermaier. The intention of such commit was to increase the SW2ISO field for i.MX6SX only, but since cpuidle-imx6sx is also used on i.MX6UL/i.MX6ULL this caused unintended side effects on other SoCs. Fix this problem by keeping the original SW2ISO value for i.MX6UL/i.MX6ULL and only increase SW2ISO in the i.MX6SX case.

Interface can0 may have been left with an inconsistent configuration, please check. | RTNETLINK answers: Connection timed out It is caused by calling of flexcan_chip_unfreeze() timeout. Originally the code is using usleep_range(10, 20) for unfreeze operation, but the patch (8badd65e can: flexcan: avoid calling usleep_range from interrupt context) changed it into udelay(10) which is only a half delay of before, there're also some other delay changes. After double to FLEXCAN_TIMEOUT_US to 100 can fix the issue. Meanwhile, Rasmus Villemoes reported that even with a timeout of 100, flexcan_probe() fails on the MPC8309, which requires a value of at least 140 to work reliably. 250 works for everyone.

[ Upstream commit 146d62e5 ] Overlapping overlay layers are not supported and can cause unexpected behavior, but overlayfs does not currently check or warn about these configurations. User is not supposed to specify the same directory for upper and lower dirs or for different lower layers and user is not supposed to specify directories that are descendants of each other for overlay layers, but that is exactly what this zysbot repro did: https://syzkaller.appspot.com/x/repro.syz?x=12c7a94f400000 Moving layer root directories into other layers while overlayfs is mounted could also result in unexpected behavior. This commit places "traps" in the overlay inode hash table. Those traps are dummy overlay inodes that are hashed by the layers root inodes. On mount, the hash table trap entries are used to verify that overlay layers are not overlapping. While at it, we also verify that overlay layers are not overlapping with directories "in-use" by other overlay instances as upperdir/workdir. On lookup, the trap entries are used to verify that overlay layers root inodes have not been moved into other layers after mount. Some examples: $ ./run --ov --samefs -s ...

[ Upstream commit ebcc5928 ] 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. Signed-off-by:

[ Upstream commit 4a60570d ] Some chips have attributes which exist on more than one page but the attribute is not presently marked as paged. This causes the attributes to be generated with the same label, which makes it impossible for userspace to tell them apart. Marking all such attributes as paged would result in the page suffix being added regardless of whether they were present on more than one page or not, which might break existing setups. Therefore, we add a second check which treats the attribute as paged, even if not marked as such, if it is present on multiple pages.

[ Upstream commit c41dd48e ] Drivers may register to hwmon and request for also registering with the thermal subsystem (HWMON_C_REGISTER_TZ). However, some of these driver, e.g. marvell phy, may be probed from Device Tree or being dynamically allocated, and in the later case, it will not have a dev->of_node entry. Registering with hwmon without the dev->of_node may result in different outcomes depending on the device tree, which may be a bit misleading. If the device tree blob has no 'thermal-zones' node, the *hwmon_device_register*() family functions are going to gracefully succeed, because of-thermal, *thermal_zone_of_sensor_register() return -ENODEV in this case, and the hwmon error path handles this error code as success to cover for the case where CONFIG_THERMAL_OF is not set. However, if the device tree blob has the 'thermal-zones' entry, the *hwmon_device_register*() will always fail on callers with no dev->of_node, propagating -EINVAL. If dev->of_node is not present, calling of-thermal does not make sense. For this reason, this patch checks first if the device has a of_node before going over the process of registering with the thermal subsystem of-thermal interface. And in this case, when a caller of *hwmon_device_register*() with HWMON_C_REGISTER_TZ and no dev->of_node will still register with hwmon, but not with the thermal subsystem. If all the hwmon part bits are in place, the registration will succeed.

[ Upstream commit 33572619 ] Enabling sysfs attribute bridge_hostnotify triggers a series of udev events for the MAC addresses of all currently connected peers. In case no VLAN is set for a peer, the device reports the corresponding MAC addresses with VLAN ID 4096. This currently results in attribute VLAN=4096 for all non-VLAN interfaces in the initial series of events after host-notify is enabled. Instead, no VLAN attribute should be reported in the udev event for non-VLAN interfaces. Only the initial events face this issue. For dynamic changes that are reported later, the device uses a validity flag. This also changes the code so that it now sets the VLAN attribute for MAC addresses with VID 0. On Linux, no qeth interface will ever be registered with VID 0: Linux kernel registers VID 0 on all network interfaces initially, but qeth will drop .ndo_vlan_rx_add_vid for VID 0. Peers with other OSs could register MACs with VID 0. Fixes: 9f48b9db ("qeth: bridgeport support - address notifications") Signed-off-by:

[ Upstream commit 0cd6783d ] While qeth_l3 uses netif_keep_dst() to hold onto the dst, a skb's dst may still have been obsoleted (via dst_dev_put()) by the time that we end up using it. The dst then points to the loopback interface, which means the neighbour lookup in qeth_l3_get_cast_type() determines a bogus cast type of RTN_BROADCAST. For IQD interfaces this causes us to place such skbs on the wrong HW queue, resulting in TX errors.

[ Upstream commit a6e04877 ] The buildtar script might want to invoke a make, so tell the parent make to pass the jobserver token pipe to the subcommand by prefixing the command with a +. This addresses the issue seen here: /bin/sh ../scripts/package/buildtar tar-pkg make[3]: warning: jobserver unavailable: using -j1. Add '+' to parent make rule. See https://www.gnu.org/software/make/manual/html_node/Job-Slots.html for more information. Signed-off-by:

[ Upstream commit 3562f5d9 ] The WRITE ZEROES command has no data transfer so that we need to initialize the struct (nvmet_req *req)->data_len to 0x0. While (nvmet_req *req)->transfer_len is initialized in nvmet_req_init(), data_len will be initialized by nowhere which might cause the failure with status code NVME_SC_SGL_INVALID_DATA | NVME_SC_DNR randomly. It's because nvmet_req_execute() checks like: if (unlikely(req->data_len != req->transfer_len)) { req->error_loc = offsetof(struct nvme_common_command, dptr); nvmet_req_complete(req, NVME_SC_SGL_INVALID_DATA | NVME_SC_DNR); } else req->execute(req); This patch fixes req->data_len not to be a randomly assigned by initializing it to 0x0 when preparing the command in nvmet_bdev_parse_io_cmd(). nvmet_file_parse_io_cmd() which is for file-backed I/O has already initialized the data_len field to 0x0, though.

[ Upstream commit 1c810739 ] On the Arm Juno platform, the HDLCD pixel clock is constrained to 250KHz resolution in order to avoid the tiny System Control Processor spending aeons trying to calculate exact PLL coefficients. This means that modes like my oddball 1600x1200 with 130.89MHz clock get rejected since the rate cannot be matched exactly. In practice, though, this mode works quite happily with the clock at 131MHz, so let's relax the check to allow a little bit of slop. Signed-off-by:

[ Upstream commit b96151ed ] Rather than allowing any old mode through, then subsequently refusing unmatchable clock rates in atomic_check when it's too late to back out and pick a different mode, let's do that validation up-front where it will cause unsupported modes to be correctly pruned in the first place. This also eliminates an issue whereby a perceived clock rate of 0 would cause atomic disable to fail and prevent the module from being unloaded. Signed-off-by:
