+
+From: Filipe Manana <fdmanana@suse.com>
+
+commit 0f475ee0ebce5c9492b260027cd95270191675fa upstream.
+
+If we failed to update the root we don't abort the transaction, which is
+wrong since we already used the transaction to remove an item from the
+uuid tree.

+
+From: Chris Spencer <spencercw@gmail.com>
+
+commit f55b9510cd9437da3a0efa08b089caeb47595ff1 upstream.
+
+This function refers to the Bosch BME680 API as the source of the
+calculation, but one of the constants does not match the Bosch
+implementation. This appears to be a simple transposition of two digits,
+resulting in a wait time that is too short. This can cause the following
+'device measurement cycle incomplete' check to occasionally fail, returning
+EBUSY to user space.
+
+Adjust the constant to match the Bosch implementation and resolve the EBUSY
+errors.

+
+commit 5187e03b817c26c1c3bcb2645a612ea935c4be89 upstream.
+
+The DS442x DAC uses sign-magnitude encoding, so -128 cannot be represented
+in hardware (7-bit magnitude).
+
+Previously, passing -128 resulted in a truncated value that programmed
+0mA (magnitude 0) instead of the expected maximum negative current,
+effectively failing silently.
+
+Reject -128 to avoid producing the wrong current.

+
+The return value of pm_runtime_get_sync() is not checked, allowing
+the driver to access hardware that may fail to resume. The device

+pm_runtime_resume_and_get() which propagates errors and avoids

+
+In preenable, add pm_runtime_put_autosuspend() on set_8khz_samplerate()
+failure since postdisable does not run when preenable fails.

+ODR switch is done in 2 steps when FIFO is on : change the ODR register

+
+commit 85e4614524dca6c0a43874f475a17de2b9725648 upstream.
+
+The MCP4131 wiper address is shifted twice when preparing the SPI
+command in mcp4131_write_raw().
+
+The address is already shifted when assigned to the local variable
+"address", but is then shifted again when written to data->buf[0].
+This results in an incorrect command being sent to the device and
+breaks wiper writes to the second channel.
+
+Remove the second shift and use the pre-shifted address directly
+when composing the SPI transfer.

+
+From: Josh Law <objecting@objecting.org>
+
+commit 560f763baa0f2c9a44da4294c06af071405ac46f upstream.
+
+The bounds check for brace_index happens after the array write.
+While the current call pattern prevents an actual out-of-bounds
+access (the previous call would have returned an error), the
+write-before-check pattern is fragile and would become a real
+out-of-bounds write if the error return were ever not propagated.
+
+Move the bounds check before the array write so the function is
+self-contained and safe regardless of caller behavior.

+Subject: lib/bootconfig: fix off-by-one in xbc_verify_tree() unclosed brace error
+
+From: Josh Law <objecting@objecting.org>
+
+commit 39ebc8d7f561e1b64eca87353ef9b18e2825e591 upstream.
+
+__xbc_open_brace() pushes entries with post-increment
+(open_brace[brace_index++]), so brace_index always points one past
+the last valid entry. xbc_verify_tree() reads open_brace[brace_index]
+to report which brace is unclosed, but this is one past the last
+pushed entry and contains stale/zero data, causing the error message
+to reference the wrong node.
+
+Use open_brace[brace_index - 1] to correctly identify the unclosed
+brace. brace_index is known to be > 0 here since we are inside the
+if (brace_index) guard.

+Subject: lib/bootconfig: fix snprintf truncation check in xbc_node_compose_key_after()
+
+From: Josh Law <objecting@objecting.org>
+
+commit 1120a36bb1e9b9e22de75ecb4ef0b998f73a97f1 upstream.
+
+snprintf() returns the number of characters that would have been
+written excluding the NUL terminator. Output is truncated when the
+return value is >= the buffer size, not just > the buffer size.
+
+When ret == size, the current code takes the non-truncated path,
+advancing buf by ret and reducing size to 0. This is wrong because
+the output was actually truncated (the last character was replaced by
+NUL). Fix by using >= so the truncation path is taken correctly.

+Subject: tracing: Fix trace_buf_size= cmdline parameter with sizes >= 2G
+
+From: Calvin Owens <calvin@wbinvd.org>
+
+commit d008ba8be8984760e36d7dcd4adbd5a41a645708 upstream.
+
+Some of the sizing logic through tracer_alloc_buffers() uses int
+internally, causing unexpected behavior if the user passes a value that
+does not fit in an int (on my x86 machine, the result is uselessly tiny
+buffers).
+
+Fix by plumbing the parameter's real type (unsigned long) through to the
+ring buffer allocation functions, which already use unsigned long.
+
+It has always been possible to create larger ring buffers via the sysfs
+interface: this only affects the cmdline parameter.

+Subject: x86/apic: Disable x2apic on resume if the kernel expects so
+
+From: Shashank Balaji <shashank.mahadasyam@sony.com>
+
+commit 8cc7dd77a1466f0ec58c03478b2e735a5b289b96 upstream.
+
+When resuming from s2ram, firmware may re-enable x2apic mode, which may have
+been disabled by the kernel during boot either because it doesn't support IRQ
+remapping or for other reasons. This causes the kernel to continue using the
+xapic interface, while the hardware is in x2apic mode, which causes hangs.
+This happens on defconfig + bare metal + s2ram.
+
+Fix this in lapic_resume() by disabling x2apic if the kernel expects it to be
+disabled, i.e. when x2apic_mode = 0.
+
+The ACPI v6.6 spec, Section 16.3 [1] says firmware restores either the
+pre-sleep configuration or initial boot configuration for each CPU, including
+MSR state:
+
+ When executing from the power-on reset vector as a result of waking from an
+ S2 or S3 sleep state, the platform firmware performs only the hardware
+ initialization required to restore the system to either the state the
+ platform was in prior to the initial operating system boot, or to the
+ pre-sleep configuration state. In multiprocessor systems, non-boot
+ processors should be placed in the same state as prior to the initial
+ operating system boot.
+
+ (further ahead)
+
+ If this is an S2 or S3 wake, then the platform runtime firmware restores
+ minimum context of the system before jumping to the waking vector. This
+ includes:
+
+ CPU configuration. Platform runtime firmware restores the pre-sleep
+ configuration or initial boot configuration of each CPU (MSR, MTRR,
+ firmware update, SMBase, and so on). Interrupts must be disabled (for
+ IA-32 processors, disabled by CLI instruction).
+
+ (and other things)
+
+So at least as per the spec, re-enablement of x2apic by the firmware is
+allowed if "x2apic on" is a part of the initial boot configuration.

+
+commit 52a8a1ba883defbfe3200baa22cf4cd21985d51a upstream.
+
+If the superblock doesn't list a log stripe unit, we set the incore log
+roundoff value to 512. This leads to corrupt logs and unmountable
+filesystems in generic/617 on a disk with 4k physical sectors...
