[PATCH 0/3] SDM630/660: Add missing MDSS reset

by unknown＠example.com

Since kernel 6.17 display stack needs to reset the hardware properly to ensure that we don't run into issues with the hardware configured by the bootloader. MDSS reset is necessary to have working display when the bootloader has already initialized it for the boot splash screen.

[PATCH v4] arm64: dts: st: Add memory-region-names property for stm32mp257f-ev1

by Patrice Chotard

In order to set the AMCR register, which configures the memory-region split between ospi1 and ospi2, we need to identify the ospi instance. By using memory-region-names, it allows to identify the ospi instance this memory-region belongs to.

Please backport commit 00d95fcc4dee ("docs: kdoc: handle the obsolescensce of docutils.ErrorString()") to v6.17.y

by Salvatore Bonaccorso

Hi When people update docutils to 0.22, then the Documentation build will start failing as documented with the commit 00d95fcc4dee ("docs: kdoc: handle the obsolescensce of docutils.ErrorString()"). So it would be nice if people can still build the documenation with newer versions (was for instance relevant for Debian unstable for building the 6.17.y based packages): https://bugs.debian.org/1118100 Thus can you please backport 00d95fcc4dee ("docs: kdoc: handle the obsolescensce of docutils.ErrorString()") down to 6.17.y stable series? The commit does not apply cleanly so adding a backport for it. Actually it would be nice to go further back, but I just tested as well 6.12.y and there due to missing faccc0ec64e1 ("docs: sphinx/kernel_abi: adjust coding style") there are more work. faccc0ec64e1 ("docs: sphinx/kernel_abi: adjust coding style") should be applicable but I'm not sure if you want to support that. Jonathan what would you think? Regards, Salvatore

[PATCH v2 1/1] mm/secretmem: fix use-after-free race in fault handler

by Lance Yang

From: Lance Yang <lance.yang(a)linux.dev> When a page fault occurs in a secret memory file created with `memfd_secret(2)`, the kernel will allocate a new folio for it, mark the underlying page as not-present in the direct map, and add it to the file mapping. If two tasks cause a fault in the same page concurrently, both could end up allocating a folio and removing the page from the direct map, but only one would succeed in adding the folio to the file mapping. The task that failed undoes the effects of its attempt by (a) freeing the folio again and (b) putting the page back into the direct map. However, by doing these two operations in this order, the page becomes available to the allocator again before it is placed back in the direct mapping. If another task attempts to allocate the page between (a) and (b), and the kernel tries to access it via the direct map, it would result in a supervisor not-present page fault. Fix the ordering to restore the direct map before the folio is freed.

[PATCH 5.10.y 0/3] v5.10: fix build with GCC 15

This kernel version doesn't build with GCC 15: In file included from include/uapi/linux/posix_types.h:5, from include/uapi/linux/types.h:14, from include/linux/types.h:6, from arch/x86/realmode/rm/wakeup.h:11, from arch/x86/realmode/rm/wakemain.c:2: include/linux/stddef.h:11:9: error: cannot use keyword 'false' as enumeration constant 11 | false = 0, | ^~~~~ include/linux/stddef.h:11:9: note: 'false' is a keyword with '-std=c23' onwards include/linux/types.h:30:33: error: 'bool' cannot be defined via 'typedef' 30 | typedef _Bool bool; | ^~~~ include/linux/types.h:30:33: note: 'bool' is a keyword with '-std=c23' onwards include/linux/types.h:30:1: warning: useless type name in empty declaration 30 | typedef _Bool bool; | ^~~~~~~ I initially fixed this by adding -std=gnu11 in arch/x86/Makefile, then I realised this fix was already done in an upstream commit, created before the GCC 15 release and not mentioning the error I had. This is the first patch. When I was investigating my error, I noticed other commits were already backported to stable versions. They were all adding -std=gnu11 in different Makefiles. In their commit message, they were mentioning 'gnu11' was picked to use the same as the one from the main Makefile. But this is not the case in this kernel version. Patch 2 fixes that. Finally, I noticed an extra warning that I didn't have in v5.15. Patch 3 fixes that.

[PATCH net V2] virtio_net: fix alignment for virtio_net_hdr_v1_hash

by Jason Wang

From: "Michael S. Tsirkin" <mst(a)redhat.com> Changing alignment of header would mean it's no longer safe to cast a 2 byte aligned pointer between formats. Use two 16 bit fields to make it 2 byte aligned as previously. This fixes the performance regression since commit ("virtio_net: enable gso over UDP tunnel support.") as it uses virtio_net_hdr_v1_hash_tunnel which embeds virtio_net_hdr_v1_hash. Pktgen in guest + XDP_DROP on TAP + vhost_net shows the TX PPS is recovered from 2.4Mpps to 4.45Mpps. Fixes: 56a06bd40fab ("virtio_net: enable gso over UDP tunnel support.")

Because the thread sc_task main function nilfs_segctor_thread() returns 0 when it succeeds, when the return value of kthread_stop() is not 0 in nilfs_segctor_destroy(), we believe that it has not properly closed sc_timer. We use timer_shutdown_sync() to sync wait for sc_timer to shutdown, and set the value of sc_task to NULL under the protection of lock sc_state_lock, so as to avoid the issue caused by sc_timer not being properly shutdowned.

[PATCH v2] usb: storage: Fix memory leak in USB bulk transport

by Desnes Nunes

A kernel memory leak was identified by the 'ioctl_sg01' test from Linux Test Project (LTP). The following bytes were mainly observed: 0x53425355. When USB storage devices incorrectly skip the data phase with status data, the code extracts/validates the CSW from the sg buffer, but fails to clear it afterwards. This leaves status protocol data in srb's transfer buffer, such as the US_BULK_CS_SIGN 'USBS' signature observed here. Thus, this can lead to USB protocols leaks to user space through SCSI generic (/dev/sg*) interfaces, such as the one seen here when the LTP test requested 512 KiB. Fix the leak by zeroing the CSW data in srb's transfer buffer immediately after the validation of devices that skip data phase. Note: Differently from CVE-2018-1000204, which fixed a big leak by zero- ing pages at allocation time, this leak occurs after allocation, when USB protocol data is written to already-allocated sg pages. v2: Use the same code style found on usb_stor_Bulk_transport() Fixes: a45b599ad808 ("scsi: sg: allocate with __GFP_ZERO in sg_build_indirect()") Cc: stable(a)vger.kernel.org Signed-off-by: Desnes Nunes <desnesn(a)redhat.com> --- drivers/usb/storage/transport.c | 12 ++++++++++++ 1 file changed, 12 insertions(+) diff --git a/drivers/usb/storage/transport.c b/drivers/usb/storage/transport.c index 1aa1bd26c81f..ee6b89f7f9ac 100644 --- a/drivers/usb/storage/transport.c +++ b/drivers/usb/storage/transport.c @@ -1200,7 +1200,19 @@ int usb_stor_Bulk_transport(struct scsi_cmnd *srb, struct us_data *us) US_BULK_CS_WRAP_LEN && bcs->Signature == cpu_to_le32(US_BULK_CS_SIGN)) { + unsigned char buf[US_BULK_CS_WRAP_LEN]; + + sg = NULL; + offset = 0; + memset(buf, 0, US_BULK_CS_WRAP_LEN); usb_stor_dbg(us, "Device skipped data phase\n"); + + if (usb_stor_access_xfer_buf(buf, + US_BULK_CS_WRAP_LEN, srb, &sg, + &offset, TO_XFER_BUF) != + US_BULK_CS_WRAP_LEN) + usb_stor_dbg(us, "Failed to clear CSW data\n"); + scsi_set_resid(srb, transfer_length); goto skipped_data_phase; } -- 2.51.0

On 32-bit systems, the kernel initializes jiffies to "-5 minutes" to make jiffies wrap bugs appear earlier. However, this causes time_before() in damon_sysfs_repeat_call_fn() to unexpectedly return true during the first 5 minutes after boot on 32-bit systems (see [1] for more explanation, which fixes another jiffies-related issue before). As a result, DAMON does not update sysfs files during that period. There is also an issue unrelated to the system's word size[2]: if the user stops DAMON just after next_update_jiffies is updated and restarts it after 'refresh_ms' or a longer delay, next_update_jiffies will retain an older value, causing time_before() to return false and the update to happen earlier than expected.

On 32-bit systems, the kernel initializes jiffies to "-5 minutes" to make jiffies wrap bugs appear earlier. However, this may cause the time_before() series of functions to return unexpected values, resulting in DAMON not functioning as intended. Meanwhile, similar issues exist in some specific user operation scenarios. This patchset addresses these issues. The first patch is about the DAMON_STAT module, and the second patch is about the core layer's sysfs. This patch (of 2): In DAMON_STAT's damon_stat_damon_call_fn(), time_before_eq() is used to avoid unnecessarily frequent stat update. On 32-bit systems, the kernel initializes jiffies to "-5 minutes" to make jiffies wrap bugs appear earlier. However, this causes time_before_eq() in DAMON_STAT to unexpectedly return true during the first 5 minutes after boot on 32-bit systems (see [1] for more explanation, which fixes another jiffies-related issue before). As a result, DAMON_STAT does not update any monitoring results during that period, which becomes more confusing when DAMON_STAT_ENABLED_DEFAULT is enabled. There is also an issue unrelated to the system's word size[2]: if the user stops DAMON_STAT just after last_refresh_jiffies is updated and restarts it after 5 seconds or a longer delay, last_refresh_jiffies will retain an older value, causing time_before_eq() to return false and the update to happen earlier than expected. Fix these issues by making last_refresh_jiffies a global variable and initializing it each time DAMON_STAT is started.

Before that change, the HVO implementation called flush_tlb_kernel_range() each time a vmemmap PMD split and remapping was performed. The mentioned commit changed this to issue a few flush_tlb_all() calls after performing all remappings. However, on s390, flush_tlb_kernel_range() expands to __tlb_flush_kernel() while flush_tlb_all() is not implemented. As a result, we went from flushing the TLB for every remapping to no flushing at all. This commit fixes this by implementing flush_tlb_all() on s390 as an alias to __tlb_flush_global(). This should cause a flush on all TLB entries on all CPUs as expected by the flush_tlb_all() semantics.

[PATCH v4] mm/huge_memory: preserve PG_has_hwpoisoned if a folio is split to >0 order

by Zi Yan

folio split clears PG_has_hwpoisoned, but the flag should be preserved in after-split folios containing pages with PG_hwpoisoned flag if the folio is split to >0 order folios. Scan all pages in a to-be-split folio to determine which after-split folios need the flag. An alternatives is to change PG_has_hwpoisoned to PG_maybe_hwpoisoned to avoid the scan and set it on all after-split folios, but resulting false positive has undesirable negative impact. To remove false positive, caller of folio_test_has_hwpoisoned() and folio_contain_hwpoisoned_page() needs to do the scan. That might be causing a hassle for current and future callers and more costly than doing the scan in the split code. More details are discussed in [1]. This issue can be exposed via: 1. splitting a has_hwpoisoned folio to >0 order from debugfs interface; 2. truncating part of a has_hwpoisoned folio in truncate_inode_partial_folio(). And later accesses to a hwpoisoned page could be possible due to the missing has_hwpoisoned folio flag. This will lead to MCE errors.

[PATCH 6.12.y] wifi: cfg80211: Add missing lock in cfg80211_check_and_end_cac()

by alvalan9＠foxmail.com

From: Alexander Wetzel <Alexander(a)wetzel-home.de> [ Upstream commit 2c5dee15239f3f3e31aa5c8808f18996c039e2c1 ] Callers of wdev_chandef() must hold the wiphy mutex. But the worker cfg80211_propagate_cac_done_wk() never takes the lock. Which triggers the warning below with the mesh_peer_connected_dfs test from hostapd and not (yet) released mac80211 code changes: WARNING: CPU: 0 PID: 495 at net/wireless/chan.c:1552 wdev_chandef+0x60/0x165 Modules linked in: CPU: 0 UID: 0 PID: 495 Comm: kworker/u4:2 Not tainted 6.14.0-rc5-wt-g03960e6f9d47 #33 13c287eeabfe1efea01c0bcc863723ab082e17cf Workqueue: cfg80211 cfg80211_propagate_cac_done_wk Stack: 00000000 00000001 ffffff00 6093267c 00000000 6002ec30 6d577c50 60037608 00000000 67e8d108 6063717b 00000000 Call Trace: [<6002ec30>] ? _printk+0x0/0x98 [<6003c2b3>] show_stack+0x10e/0x11a [<6002ec30>] ? _printk+0x0/0x98 [<60037608>] dump_stack_lvl+0x71/0xb8 [<6063717b>] ? wdev_chandef+0x60/0x165 [<6003766d>] dump_stack+0x1e/0x20 [<6005d1b7>] __warn+0x101/0x20f [<6005d3a8>] warn_slowpath_fmt+0xe3/0x15d [<600b0c5c>] ? mark_lock.part.0+0x0/0x4ec [<60751191>] ? __this_cpu_preempt_check+0x0/0x16 [<600b11a2>] ? mark_held_locks+0x5a/0x6e [<6005d2c5>] ? warn_slowpath_fmt+0x0/0x15d [<60052e53>] ? unblock_signals+0x3a/0xe7 [<60052f2d>] ? um_set_signals+0x2d/0x43 [<60751191>] ? __this_cpu_preempt_check+0x0/0x16 [<607508b2>] ? lock_is_held_type+0x207/0x21f [<6063717b>] wdev_chandef+0x60/0x165 [<605f89b4>] regulatory_propagate_dfs_state+0x247/0x43f [<60052f00>] ? um_set_signals+0x0/0x43 [<605e6bfd>] cfg80211_propagate_cac_done_wk+0x3a/0x4a [<6007e460>] process_scheduled_works+0x3bc/0x60e [<6007d0ec>] ? move_linked_works+0x4d/0x81 [<6007d120>] ? assign_work+0x0/0xaa [<6007f81f>] worker_thread+0x220/0x2dc [<600786ef>] ? set_pf_worker+0x0/0x57 [<60087c96>] ? to_kthread+0x0/0x43 [<6008ab3c>] kthread+0x2d3/0x2e2 [<6007f5ff>] ? worker_thread+0x0/0x2dc [<6006c05b>] ? calculate_sigpending+0x0/0x56 [<6003b37d>] new_thread_handler+0x4a/0x64 irq event stamp: 614611 hardirqs last enabled at (614621): [<00000000600bc96b>] __up_console_sem+0x82/0xaf hardirqs last disabled at (614630): [<00000000600bc92c>] __up_console_sem+0x43/0xaf softirqs last enabled at (614268): [<00000000606c55c6>] __ieee80211_wake_queue+0x933/0x985 softirqs last disabled at (614266): [<00000000606c52d6>] __ieee80211_wake_queue+0x643/0x985 Fixes: 26ec17a1dc5e ("cfg80211: Fix radar event during another phy CAC") Signed-off-by: Alexander Wetzel <Alexander(a)wetzel-home.de> Link: https://patch.msgid.link/20250717162547.94582-1-Alexander@wetzel-home.de Signed-off-by: Johannes Berg <johannes.berg(a)intel.com> [ The author recommends that when porting to older kernels, we should use wiphy_lock() and wiphy_unlock() instead of guard().
