+Subject: 6lowpan: iphc: reset mac_header after decompress to fix panic
+
+From: Michael Scott <michael@opensourcefoundries.com>
+
+[ Upstream commit 03bc05e1a4972f73b4eb8907aa373369e825c252 ]
+
+After decompression of 6lowpan socket data, an IPv6 header is inserted
+before the existing socket payload. After this, we reset the
+network_header value of the skb to account for the difference in payload
+size from prior to decompression + the addition of the IPv6 header.
+
+However, we fail to reset the mac_header value.
+
+Leaving the mac_header value untouched here, can cause a calculation
+error in net/packet/af_packet.c packet_rcv() function when an
+AF_PACKET socket is opened in SOCK_RAW mode for use on a 6lowpan
+interface.
+
+On line 2088, the data pointer is moved backward by the value returned
+from skb_mac_header(). If skb->data is adjusted so that it is before
+the skb->head pointer (which can happen when an old value of mac_header
+is left in place) the kernel generates a panic in net/core/skbuff.c
+line 1717.
+
+This panic can be generated by BLE 6lowpan interfaces (such as bt0) and
+802.15.4 interfaces (such as lowpan0) as they both use the same 6lowpan
+sources for compression and decompression.

+alarm_timer_nsleep() uses ktime_add() to add the current time and the

+Use ktime_add_safe() which has the necessary sanity checks in place and

+
+From: Dave Gerlach <d-gerlach@ti.com>
+
+[ Upstream commit 6d609b35c815ba20132b7b64bcca04516bb17c56 ]
+
+When the RTC lock and unlock functions were introduced it was likely
+assumed that they would always be called from irq enabled context, hence
+the use of local_irq_disable/enable. This is no longer true as the
+RTC+DDR path makes a late call during the suspend path after irqs
+have been disabled to enable the RTC hwmod which calls both unlock and
+lock, leading to IRQs being reenabled through the local_irq_enable call
+in omap_hwmod_rtc_lock call.
+
+To avoid this change the local_irq_disable/enable to
+local_irq_save/restore to ensure that from whatever context this is
+called the proper IRQ configuration is maintained.

+From: Ethan Tuttle <ethan@ethantuttle.com>
+
+[ Upstream commit d0d378ff451a66e486488eec842e507d28145813 ]
+
+With CONFIG_FORTIFY_SOURCE, memcpy uses the declared size of operands to
+detect buffer overflows. If src or dest is declared as a char, attempts to
+copy more than byte will result in a fortify_panic().
+
+Address this problem in mvebu_setup_boot_addr_wa() by declaring
+mvebu_boot_wa_start and mvebu_boot_wa_end as character arrays. Also remove
+a couple addressof operators to avoid "arithmetic on pointer to an
+incomplete type" compiler error.
+
+See commit 54a7d50b9205 ("x86: mark kprobe templates as character arrays,
+not single characters") for a similar fix.

+Subject: audit: Fix extended comparison of GID/EGID
+
+From: "Ondrej Mosnáček" <omosnace@redhat.com>
+
+[ Upstream commit af85d1772e31fed34165a1b3decef340cf4080c0 ]
+
+The audit_filter_rules() function in auditsc.c used the in_[e]group_p()
+functions to check GID/EGID match, but these functions use the current
+task's credentials, while the comparison should use the credentials of
+the task given to audit_filter_rules() as a parameter (tsk).
+
+Note that we can use group_search(cred->group_info, ...) as a
+replacement for both in_group_p and in_egroup_p as these functions only
+compare the parameter to cred->fsgid/egid and then call group_search.
+
+In fact, the usage of in_group_p was even more incorrect: it compares to
+cred->fsgid (which is usually equal to cred->egid) and not cred->gid.

+could write to the suspend_area even the suspend_area
+is not handled by any node, because area_resyncing
+returns 0 at the beginning of raid1_write_request.
+Which means one node could write suspend_area while
+another node is resyncing the same area, then data
+could be inconsistent.
+
+So let's clear suspend_area later to avoid above issue
+with the protection of bm lock. Also it is straightforward
+to clear suspend_area after nodes have copied the resync
+info to bitmap.

+Subject: media: omap3isp: zero-initialize the isp cam_xclk{a,b} initial data
+
+From: Javier Martinez Canillas <javierm@redhat.com>
+
+[ Upstream commit 2ec7debd44b49927a6e2861521994cc075a389ed ]
+
+The struct clk_init_data init variable is declared in the isp_xclk_init()
+function so is an automatic variable allocated in the stack. But it's not
+explicitly zero-initialized, so some init fields are left uninitialized.
+
+This causes the data structure to have undefined values that may confuse
+the common clock framework when the clock is registered.
+
+For example, the uninitialized .flags field could have the CLK_IS_CRITICAL
+bit set, causing the framework to wrongly prepare the clk on registration.
+This leads to the isp_xclk_prepare() callback being called, which in turn
+calls to the omap3isp_get() function that increments the isp dev refcount.
+
+Since this omap3isp_get() call is unexpected, this leads to an unbalanced
+omap3isp_get() call that prevents the requested IRQ to be later enabled,
+due the refcount not being 0 when the correct omap3isp_get() call happens.

+When the subdevice doesn't provide s_power core ops callback, the

+Subject: media: soc_camera: ov772x: correct setting of banding filter
+
+From: Akinobu Mita <akinobu.mita@gmail.com>
+
+[ Upstream commit 22216ec41e919682c15345e95928f266e8ba6f9e ]
+
+The banding filter ON/OFF is controlled via bit 5 of COM8 register. It
+is attempted to be enabled in ov772x_set_params() by the following line.
+
+ ret = ov772x_mask_set(client, COM8, BNDF_ON_OFF, 1);
+
+But this unexpectedly results disabling the banding filter, because the
+mask and set bits are exclusive.
+
+On the other hand, ov772x_s_ctrl() correctly sets the bit by:
+
+ ret = ov772x_mask_set(client, COM8, BNDF_ON_OFF, BNDF_ON_OFF);
+
+The same fix was already applied to non-soc_camera version of ov772x
+driver in the commit commit a024ee14cd36 ("media: ov772x: correct setting
+of banding filter")

+Subject: module: exclude SHN_UNDEF symbols from kallsyms api
+
+From: Jessica Yu <jeyu@kernel.org>
+
+[ Upstream commit 9f2d1e68cf4d641def734adaccfc3823d3575e6c ]
+
+Livepatch modules are special in that we preserve their entire symbol
+tables in order to be able to apply relocations after module load. The
+unwanted side effect of this is that undefined (SHN_UNDEF) symbols of
+livepatch modules are accessible via the kallsyms api and this can
+confuse symbol resolution in livepatch (klp_find_object_symbol()) and
+cause subtle bugs in livepatch.
+
+Have the module kallsyms api skip over SHN_UNDEF symbols. These symbols
+are usually not available for normal modules anyway as we cut down their
+symbol tables to just the core (non-undefined) symbols, so this should
+really just affect livepatch modules. Note that this patch doesn't
+affect the display of undefined symbols in /proc/kallsyms.

+Subject: perf/x86/intel/lbr: Fix incomplete LBR call stack
+
+From: Kan Liang <kan.liang@linux.intel.com>
+
+[ Upstream commit 0592e57b24e7e05ec1f4c50b9666c013abff7017 ]
+
+LBR has a limited stack size. If a task has a deeper call stack than
+LBR's stack size, only the overflowed part is reported. A complete call
+stack may not be reconstructed by perf tool.
+
+Current code doesn't access all LBR registers. It only read the ones
+below the TOS. The LBR registers above the TOS will be discarded
+unconditionally.
+
+When a CALL is captured, the TOS is incremented by 1 , modulo max LBR
+stack size. The LBR HW only records the call stack information to the
+register which the TOS points to. It will not touch other LBR
+registers. So the registers above the TOS probably still store the valid
+call stack information for an overflowed call stack, which need to be
+reported.
+
+To retrieve complete call stack information, we need to start from TOS,
+read all LBR registers until an invalid entry is detected.
+0s can be used to detect the invalid entry, because:
+
+ - When a RET is captured, the HW zeros the LBR register which TOS points
+ to, then decreases the TOS.
+ - The LBR registers are reset to 0 when adding a new LBR event or
+ scheduling an existing LBR event.
+ - A taken branch at IP 0 is not expected
+
+The context switch code is also modified to save/restore all valid LBR
+registers. Furthermore, the LBR registers, which don't have valid call
+stack information, need to be reset in restore, because they may be
+polluted while swapped out.
+
+Here is a small test program, tchain_deep.
+Its call stack is deeper than 32.
+
+ noinline void f33(void)
+ {
+ int i;
+
+ for (i = 0; i < 10000000;) {
+ if (i%2)
+ i++;
+ else
+ i++;
+ }
+ }
+
+ noinline void f32(void)
+ {
+ f33();
+ }
+
+ noinline void f31(void)
+ {
+ f32();
+ }
+
+ ... ...
+
+ noinline void f1(void)
+ {
+ f2();
+ }
+
+ int main()
+ {
+ f1();
+ }
+
+Here is the test result on SKX. The max stack size of SKX is 32.
+
+Without the patch:
+
+ $ perf record -e cycles --call-graph lbr -- ./tchain_deep
+ $ perf report --stdio
+ #
+ # Children Self Command Shared Object Symbol
+ # ........ ........ ........... ................ .................

+ |
+ --99.99%--f30

+
+With the patch:

+ $ perf record -e cycles --call-graph lbr -- ./tchain_deep
+ $ perf report --stdio
+ # Children Self Command Shared Object Symbol
+ # ........ ........ ........... ................ ..................

+From: Benjamin Tissoires <benjamin.tissoires@redhat.com>
+
+[ Upstream commit 3ffa6583e24e1ad1abab836d24bfc9d2308074e5 ]
+
+If a device gets removed right after having registered a power_supply node,
+we might enter in a deadlock between the remove call (that has a lock on
+the parent device) and the deferred register work.
+
+Allow the deferred register work to exit without taking the lock when
+we are in the remove state.

+Subject: power: vexpress: fix corruption in notifier registration
+
+From: Sudeep Holla <sudeep.holla@arm.com>
+
+[ Upstream commit 09bebb1adb21ecd04adf7ccb3b06f73e3a851e93 ]
+
+Vexpress platforms provide two different restart handlers: SYS_REBOOT
+that restart the entire system, while DB_RESET only restarts the
+daughter board containing the CPU. DB_RESET is overridden by SYS_REBOOT
+if it exists.
+
+notifier_chain_register used in register_restart_handler by design
+relies on notifiers to be registered once only, however vexpress restart
+notifier can get registered twice. When this happen it corrupts list
+of notifiers, as result some notifiers can be not called on proper
+event, traverse on list can be cycled forever, and second unregister
+can access already freed memory.
+
+So far, since this was the only restart handler in the system, no issue
+was observed even if the same notifier was registered twice. However
+commit 6c5c0d48b686 ("watchdog: sp805: add restart handler") added
+support for SP805 restart handlers and since the system under test
+contains two vexpress restart and two SP805 watchdog instances, it was
+observed that during the boot traversing the restart handler list looped
+forever as there's a cycle in that list resulting in boot hang.
+
+This patch fixes the issues by ensuring that the notifier is installed
+only once.

+
+From: Alexey Kardashevskiy <aik@ozlabs.ru>
+
+[ Upstream commit d3d4ffaae439981e1e441ebb125aa3588627c5d8 ]
+
+We use PHB in mode1 which uses bit 59 to select a correct DMA window.
+However there is mode2 which uses bits 59:55 and allows up to 32 DMA
+windows per a PE.
+
+Even though documentation does not clearly specify that, it seems that
+the actual hardware does not support bits 59:55 even in mode1, in other
+words we can create a window as big as 1<<58 but DMA simply won't work.
+
+This reduces the upper limit from 59 to 55 bits to let the userspace know
+about the hardware limits.

+Subject: rndis_wlan: potential buffer overflow in rndis_wlan_auth_indication()
+
+From: Dan Carpenter <dan.carpenter@oracle.com>
+
+[ Upstream commit ae636fb1554833ee5133ca47bf4b2791b6739c52 ]
+
+This is a static checker fix, not something I have tested. The issue
+is that on the second iteration through the loop, we jump forward by
+le32_to_cpu(auth_req->length) bytes. The problem is that if the length
+is more than "buflen" then we end up with a negative "buflen". A
+negative buflen is type promoted to a high positive value and the loop
+continues but it's accessing beyond the end of the buffer.
+
+I believe the "auth_req->length" comes from the firmware and if the
+firmware is malicious or buggy, you're already toasted so the impact of
+this bug is probably not very severe.

+ strncat(seg->res_name, " (DCSS)", 7);
+
+What gcc complains about here is the misuse of strncat function, which
+in this case does not limit a number of bytes taken from "src", so it is
+in the end the same as strcat(seg->res_name, " (DCSS)");
+
+Keeping in mind that a res_name is 15 bytes, strncat in this case
+would overflow the buffer and write 0 into alignment byte between the
+fields in the struct. To avoid that increasing res_name size to 16,
+and reusing strlcat.

+
+From: Breno Leitao <leitao@debian.org>
+
+[ Upstream commit 1262dc09dc9ae7bf4ad00b6a2c5ed6a6936bcd10 ]
+
+Currently an open firmware property is copied into partition_name variable
+without keeping a room for \0.
+
+Later one, this variable (partition_name), which is 97 bytes long, is
+strncpyed into ibmvcsci_host_data->madapter_info->partition_name, which is
+96 bytes long, possibly truncating it 'again' and removing the \0.
+
+This patch simply decreases the partition name to 96 and just copy using
+strlcpy() which guarantees that the string is \0 terminated. I think there
+is no issue if this there is a truncation in this very first copy, i.e,
+when the open firmware property is read and copied into the driver for the
+very first time;
+
+This issue also causes the following warning on GCC 8:

+From: Alistair Strachan <astrachan@google.com>
+
+[ Upstream commit 8632c614565d0c5fdde527889601c018e97b6384 ]
+
+The ashmem driver did not check that the size/offset of the vma passed
+to its .mmap() function was not larger than the ashmem object being
+mapped. This could cause mmap() to succeed, even though accessing parts
+of the mapping would later fail with a segmentation fault.
+
+Ensure an error is returned by the ashmem_mmap() function if the vma
+size is larger than the ashmem object size. This enables safer handling
+of the problem in userspace.

+
+[ Upstream commit ce054546cc2c26891cefa2f284d90d93b52205de ]
+
+ADC channel 0 photodiode detects both infrared + visible light,
+but ADC channel 1 just detects infrared. However, the latter is a bit
+more sensitive in that range so complete darkness or low light causes
+a error condition in which the chan0 - chan1 is negative that
+results in a -EAGAIN.
+
+This patch changes the resulting lux1_input sysfs attribute message from
+"Resource temporarily unavailable" to a user-grokable lux value of 0.

+
+... there are two more instances which want to be adjusted.
+
+As said there, omitting suffixes from instructions in AT&T mode is bad

+gas in the future (mine does already).
+
+Add the other missing suffixes here as well.

+Subject: x86/numa_emulation: Fix emulated-to-physical node mapping
+
+From: Dan Williams <dan.j.williams@intel.com>
+
+[ Upstream commit 3b6c62f363a19ce82bf378187ab97c9dc01e3927 ]
+
+Without this change the distance table calculation for emulated nodes
+may use the wrong numa node and report an incorrect distance.
