+Subject: compiler-clang.h: define __SANITIZE_*__ macros only when undefined
+
+From: Nathan Chancellor <nathan@kernel.org>
+
+commit 3fac212fe489aa0dbe8d80a42a7809840ca7b0f9 upstream.
+
+Clang 22 recently added support for defining __SANITIZE__ macros similar
+to GCC [1], which causes warnings (or errors with CONFIG_WERROR=y or W=e)
+with the existing defines that the kernel creates to emulate this behavior
+with existing clang versions.
+
+ In file included from <built-in>:3:
+ In file included from include/linux/compiler_types.h:171:
+ include/linux/compiler-clang.h:37:9: error: '__SANITIZE_THREAD__' macro redefined [-Werror,-Wmacro-redefined]
+ 37 | #define __SANITIZE_THREAD__
+ | ^
+ <built-in>:352:9: note: previous definition is here
+ 352 | #define __SANITIZE_THREAD__ 1
+ | ^
+
+Refactor compiler-clang.h to only define the sanitizer macros when they
+are undefined and adjust the rest of the code to use these macros for
+checking if the sanitizers are enabled, clearing up the warnings and
+allowing the kernel to easily drop these defines when the minimum
+supported version of LLVM for building the kernel becomes 22.0.0 or newer.

+
+From: Johan Hovold <johan@kernel.org>
+
+commit 4de37a48b6b58faaded9eb765047cf0d8785ea18 upstream.
+
+The for_each_child_of_node() helper drops the reference it takes to each
+node as it iterates over children and an explicit of_node_put() is only
+needed when exiting the loop early.
+
+Drop the recently introduced bogus additional reference count decrement
+at each iteration that could potentially lead to a use-after-free.

+
+From: Miklos Szeredi <mszeredi@redhat.com>
+
+commit 1e08938c3694f707bb165535df352ac97a8c75c9 upstream.
+
+The FUSE protocol uses struct fuse_write_out to convey the return value of
+copy_file_range, which is restricted to uint32_t. But the COPY_FILE_RANGE
+interface supports a 64-bit size copies.
+
+Currently the number of bytes copied is silently truncated to 32-bit, which
+may result in poor performance or even failure to copy in case of
+truncation to zero.

+Subject: mm/damon/core: set quota->charged_from to jiffies at first charge window
+
+From: Sang-Heon Jeon <ekffu200098@gmail.com>
+
+commit ce652aac9c90a96c6536681d17518efb1f660fb8 upstream.
+
+Kernel initializes the "jiffies" timer as 5 minutes below zero, as shown
+in include/linux/jiffies.h
+
+ /*
+ * Have the 32 bit jiffies value wrap 5 minutes after boot
+ * so jiffies wrap bugs show up earlier.
+ */
+ #define INITIAL_JIFFIES ((unsigned long)(unsigned int) (-300*HZ))
+
+And jiffies comparison help functions cast unsigned value to signed to
+cover wraparound
+
+ #define time_after_eq(a,b) \
+ (typecheck(unsigned long, a) && \
+ typecheck(unsigned long, b) && \
+ ((long)((a) - (b)) >= 0))
+
+When quota->charged_from is initialized to 0, time_after_eq() can
+incorrectly return FALSE even after reset_interval has elapsed. This
+occurs when (jiffies - reset_interval) produces a value with MSB=1, which
+is interpreted as negative in signed arithmetic.
+
+This issue primarily affects 32-bit systems because: On 64-bit systems:
+MSB=1 values occur after ~292 million years from boot (assuming HZ=1000),
+almost impossible.
+
+On 32-bit systems: MSB=1 values occur during the first 5 minutes after
+boot, and the second half of every jiffies wraparound cycle, starting from
+day 25 (assuming HZ=1000)
+
+When above unexpected FALSE return from time_after_eq() occurs, the
+charging window will not reset. The user impact depends on esz value at
+that time.
+
+If esz is 0, scheme ignores configured quotas and runs without any limits.
+
+If esz is not 0, scheme stops working once the quota is exhausted. It
+remains until the charging window finally resets.
+
+So, change quota->charged_from to jiffies at damos_adjust_quota() when it
+is considered as the first charge window. By this change, we can avoid
+unexpected FALSE return from time_after_eq()

+Kernel panic - not syncing: Fatal exception
+Kernel Offset: 0x31c00000 from 0xffffffff81000000 (relocation range: 0xffffffff80000000-0xffffffffbfffffff)
+---[ end Kernel panic - not syncing: Fatal exception ]---
+
+The root cause is that unpoison_memory() tries to check the PG_HWPoison
+flags of an uninitialized page. So VM_BUG_ON_PAGE(PagePoisoned(page)) is
+triggered. This can be reproduced by below steps:
+
+1.Offline memory block:
+
+ echo offline > /sys/devices/system/memory/memory12/state
+
+2.Get offlined memory pfn:
+
+ page-types -b n -rlN
+
+3.Write pfn to unpoison-pfn
+
+ echo <pfn> > /sys/kernel/debug/hwpoison/unpoison-pfn
+
+This scenario can be identified by pfn_to_online_page() returning NULL.
+And ZONE_DEVICE pages are never expected, so we can simply fail if
+pfn_to_online_page() == NULL to fix the bug.

+Subject: mptcp: sockopt: make sync_socket_options propagate SOCK_KEEPOPEN
+
+From: Krister Johansen <kjlx@templeofstupid.com>
+
+commit 648de37416b301f046f62f1b65715c7fa8ebaa67 upstream.
+
+Users reported a scenario where MPTCP connections that were configured
+with SO_KEEPALIVE prior to connect would fail to enable their keepalives
+if MTPCP fell back to TCP mode.
+
+After investigating, this affects keepalives for any connection where
+sync_socket_options is called on a socket that is in the closed or
+listening state. Joins are handled properly. For connects,
+sync_socket_options is called when the socket is still in the closed
+state. The tcp_set_keepalive() function does not act on sockets that
+are closed or listening, hence keepalive is not immediately enabled.
+Since the SO_KEEPOPEN flag is absent, it is not enabled later in the
+connect sequence via tcp_finish_connect. Setting the keepalive via
+sockopt after connect does work, but would not address any subsequently
+created flows.
+
+Fortunately, the fix here is straight-forward: set SOCK_KEEPOPEN on the
+subflow when calling sync_socket_options.
+
+The fix was valdidated both by using tcpdump to observe keepalive
+packets not being sent before the fix, and being sent after the fix. It
+was also possible to observe via ss that the keepalive timer was not
+enabled on these sockets before the fix, but was enabled afterwards.

+
+commit 811c0da4542df3c065f6cb843ced68780e27bb44 upstream.
+
+In case OOB write is requested during a data write, ECC is currently
+lost. Avoid this issue by only writing in the free spare area.
+This issue has been seen with a YAFFS2 file system.

+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+From: Oleksij Rempel <o.rempel@pengutronix.de>
+
+commit 5537a4679403423e0b49c95b619983a4583d69c5 upstream.
+
+Drop phylink_{suspend,resume}() from ax88772 PM callbacks.
+
+MDIO bus accesses have their own runtime-PM handling and will try to
+wake the device if it is suspended. Such wake attempts must not happen
+from PM callbacks while the device PM lock is held. Since phylink
+{sus|re}sume may trigger MDIO, it must not be called in PM context.
+
+No extra phylink PM handling is required for this driver:
+- .ndo_open/.ndo_stop control the phylink start/stop lifecycle.
+- ethtool/phylib entry points run in process context, not PM.
+- phylink MAC ops program the MAC on link changes after resume.
+

+ocfs2_fiemap() takes a read lock of the ip_alloc_sem semaphore (since
+v2.6.22-527-g7307de80510a) and calls fiemap_fill_next_extent() to read the
+extent list of this running mmap executable. The user supplied buffer to
+hold the fiemap information page faults calling ocfs2_page_mkwrite() which
+will take a write lock (since v2.6.27-38-g00dc417fa3e7) of the same
+semaphore. This recursive semaphore will hold filesystem locks and causes
+a hang of the fileystem.
+
+The ip_alloc_sem protects the inode extent list and size. Release the
+read semphore before calling fiemap_fill_next_extent() in ocfs2_fiemap()
+and ocfs2_fiemap_inline(). This does an unnecessary semaphore lock/unlock
+on the last extent but simplifies the error path.
