[PATCH] HID: multitouch: fix integer overflow in set_abs()

by Qasim Ijaz

It is possible for a malicious HID device to trigger a signed integer overflow (undefined behaviour) in set_abs() in the following expression by supplying bogus logical maximum and minimum values: int fuzz = snratio ? (fmax - fmin) / snratio : 0; For example, if the logical_maximum is INT_MAX and logical_minimum is -1 then (fmax - fmin) resolves to INT_MAX + 1, which does not fit in a 32-bit signed int, so the subtraction overflows. Fix this by computing the difference in a 64 bit context.

[PATCH AUTOSEL 6.16-5.10] block: avoid possible overflow for chunk_sectors check in blk_stack_limits()

by Sasha Levin

From: John Garry <john.g.garry(a)oracle.com> [ Upstream commit 448dfecc7ff807822ecd47a5c052acedca7d09e8 ] In blk_stack_limits(), we check that the t->chunk_sectors value is a multiple of the t->physical_block_size value. However, by finding the chunk_sectors value in bytes, we may overflow the unsigned int which holds chunk_sectors, so change the check to be based on sectors. Reviewed-by: Hannes Reinecke <hare(a)suse.de> Reviewed-by: Martin K. Petersen <martin.petersen(a)oracle.com> Signed-off-by: John Garry <john.g.garry(a)oracle.com> Reviewed-by: Damien Le Moal <dlemoal(a)kernel.org> Link: https://lore.kernel.org/r/20250729091448.1691334-2-john.g.garry@oracle.com Signed-off-by: Jens Axboe <axboe(a)kernel.dk> Signed-off-by: Sasha Levin <sashal(a)kernel.org> --- LLM Generated explanations, may be completely bogus: **Backport Status: YES** ## Extensive Analysis This commit should be backported to stable kernel trees for the following reasons: ### 1. **It fixes a real integer overflow bug** The original code performs `(t->chunk_sectors << 9)` which can cause an integer overflow. Since both `chunk_sectors` and `physical_block_size` are `unsigned int` (32-bit), when `chunk_sectors` is larger than 8,388,607 (2^23 - 1), shifting it left by 9 bits (multiplying by 512) will overflow the 32-bit unsigned integer. This overflow can lead to incorrect alignment checks. ### 2. **The fix is minimal and contained** The change is a single-line modification that replaces: ```c if ((t->chunk_sectors << 9) & (t->physical_block_size - 1)) ``` with: ```c if (t->chunk_sectors % (t->physical_block_size >> SECTOR_SHIFT)) ``` This mathematically equivalent check avoids the overflow by dividing `physical_block_size` by the sector size (512 bytes) instead of multiplying `chunk_sectors` by 512. ### 3. **It's a correctness issue in critical block layer code** The `blk_stack_limits()` function is fundamental to the block layer's device stacking functionality, used by MD, DM, and other stacked block devices. An overflow here could lead to: - Incorrect alignment detection - Improper chunk_sectors being cleared when it shouldn't be - Potential data corruption or I/O errors in stacked block devices ### 4. **The fix has low regression risk** - The new calculation is mathematically equivalent to the intended check - It only changes how the comparison is performed, not the logic - The fix has been reviewed by multiple maintainers (Hannes Reinecke, Martin K. Petersen, Damien Le Moal) - No new features or architectural changes are introduced ### 5. **Real-world impact potential** Modern storage devices can have large chunk sizes. For example: - NVMe devices with large zones could have chunk_sectors approaching or exceeding the overflow threshold - RAID configurations with large stripe sizes - This becomes more likely as storage devices grow in capacity and complexity ### 6. **Follows stable kernel criteria** According to stable kernel rules, this qualifies because it: - Fixes a bug that users can potentially hit - Is obviously correct and tested - Is small (single line change) - Fixes only one thing - Has no dependencies on other patches The commit message clearly describes the problem (overflow in unsigned int) and the solution (changing the check to avoid overflow). The fix maintains the same semantic meaning while being overflow-safe, making it an ideal candidate for stable backporting. block/blk-settings.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/block/blk-settings.c b/block/blk-settings.c index a000daafbfb4..88890e904320 100644 --- a/block/blk-settings.c +++ b/block/blk-settings.c @@ -779,7 +779,7 @@ int blk_stack_limits(struct queue_limits *t, struct queue_limits *b, } /* chunk_sectors a multiple of the physical block size? */ - if ((t->chunk_sectors << 9) & (t->physical_block_size - 1)) { + if (t->chunk_sectors % (t->physical_block_size >> SECTOR_SHIFT)) { t->chunk_sectors = 0; t->flags |= BLK_FLAG_MISALIGNED; ret = -1; -- 2.39.5

[PATCH] riscv: Only allow LTO with CMODEL_MEDANY

by Nathan Chancellor

When building with CONFIG_CMODEL_MEDLOW and CONFIG_LTO_CLANG, there is a series of errors due to some files being unconditionally compiled with '-mcmodel=medany', mismatching with the rest of the kernel built with '-mcmodel=medlow': ld.lld: error: Function Import: link error: linking module flags 'Code Model': IDs have conflicting values: 'i32 3' from vmlinux.a(init.o at 899908), and 'i32 1' from vmlinux.a(net-traces.o at 1014628) Only allow LTO to be performed when CONFIG_CMODEL_MEDANY is enabled to ensure there will be no code model mismatch errors. An alternative solution would be disabling LTO for the files with a different code model than the main kernel like some specialized areas of the kernel do but doing that for individual files is not as sustainable than forbidding the combination altogether.

[PATCH AUTOSEL 6.16-5.4] kconfig: gconf: avoid hardcoding model2 in on_treeview2_cursor_changed()

by Sasha Levin

From: Masahiro Yamada <masahiroy(a)kernel.org> [ Upstream commit cae9cdbcd9af044810bcceeb43a87accca47c71d ] The on_treeview2_cursor_changed() handler is connected to both the left and right tree views, but it hardcodes model2 (the GtkTreeModel of the right tree view). This is incorrect. Get the associated model from the view. Signed-off-by: Masahiro Yamada <masahiroy(a)kernel.org> Signed-off-by: Sasha Levin <sashal(a)kernel.org> --- LLM Generated explanations, may be completely bogus: Let me check the commit you provided more carefully. Looking at the diff: The commit changes line 851-852 in the `on_treeview2_cursor_changed` function from: ```c if (gtk_tree_selection_get_selected(selection, &model2, &iter)) { gtk_tree_model_get(model2, &iter, COL_MENU, &menu, -1); ``` To: ```c if (gtk_tree_selection_get_selected(selection, &model, &iter)) { gtk_tree_model_get(model, &iter, COL_MENU, &menu, -1); ``` Where `model` is obtained from: `GtkTreeModel *model = gtk_tree_view_get_model(treeview);` This is indeed a bug fix. The function `on_treeview2_cursor_changed()` is connected as a signal handler to BOTH tree views (tree1_w and tree2_w), as shown in the connection code around lines 989 and 997. However, the old code hardcoded `model2` which is specifically the model for the right tree view. This would cause incorrect behavior when the handler is triggered from the left tree view (tree1_w). **Backport Status: YES** ## Extensive Analysis: ### Bug Description: The commit fixes a clear bug in the gconf GUI tool for kernel configuration. The `on_treeview2_cursor_changed()` function is used as a signal handler for cursor changes in both the left and right tree views of the configuration interface. However, the function incorrectly hardcoded `model2` (the GtkTreeModel for the right tree view) instead of dynamically getting the model from whichever view triggered the event. ### Code Analysis: 1. **Signal Connection** (lines 988-997 in the repository): - The same handler is connected to both tree views: ```c g_signal_connect(tree1_w, "cursor-changed", G_CALLBACK(on_treeview2_cursor_changed), NULL); g_signal_connect(tree2_w, "cursor-changed", G_CALLBACK(on_treeview2_cursor_changed), NULL); ``` 2. **The Bug**: When the cursor changes in tree1_w (left tree), the handler would incorrectly use model2 (right tree's model) to get the selected item, potentially causing: - Incorrect help text display - Crashes if the models have different structures - Undefined behavior when accessing invalid iterators 3. **The Fix**: The commit correctly obtains the model from the treeview parameter that triggered the event: ```c GtkTreeModel *model = gtk_tree_view_get_model(treeview); ``` This ensures the correct model is used regardless of which tree view triggered the event. ### Backport Justification: 1. **Clear Bug Fix**: This fixes an obvious programming error that affects functionality 2. **Small and Contained**: The change is minimal (2 lines modified) and localized to a single function 3. **Low Risk**: The fix is straightforward and correct - getting the model from the actual tree view instead of hardcoding 4. **User Impact**: This bug could affect users of the gconf configuration tool, potentially causing crashes or incorrect behavior 5. **No Architectural Changes**: This is a simple bug fix with no design changes 6. **No New Features**: Pure bug fix, no functionality additions This is an ideal candidate for stable backporting as it's a clear, minimal bug fix that improves reliability without introducing risk. scripts/kconfig/gconf.c | 5 +++-- 1 file changed, 3 insertions(+), 2 deletions(-) diff --git a/scripts/kconfig/gconf.c b/scripts/kconfig/gconf.c index c0f46f189060..abe4cfe66b14 100644 --- a/scripts/kconfig/gconf.c +++ b/scripts/kconfig/gconf.c @@ -942,13 +942,14 @@ on_treeview2_key_press_event(GtkWidget * widget, void on_treeview2_cursor_changed(GtkTreeView * treeview, gpointer user_data) { + GtkTreeModel *model = gtk_tree_view_get_model(treeview); GtkTreeSelection *selection; GtkTreeIter iter; struct menu *menu; selection = gtk_tree_view_get_selection(treeview); - if (gtk_tree_selection_get_selected(selection, &model2, &iter)) { - gtk_tree_model_get(model2, &iter, COL_MENU, &menu, -1); + if (gtk_tree_selection_get_selected(selection, &model, &iter)) { + gtk_tree_model_get(model, &iter, COL_MENU, &menu, -1); text_insert_help(menu); } } -- 2.39.5

[PATCH i2c-host-fixes v4 0/5] i2c: rtl9300: Fix multi-byte I2C operations

by Sven Eckelmann

During the integration of the RTL8239 POE chip + its frontend MCU, it was noticed that multi-byte operations were basically broken in the current driver. Tests using SMBus Block Writes showed that the data (after the Wr maker + Ack) was mixed up on the wire. At first glance, it looked like an endianness problem. But for transfers where the number of count + data bytes was not divisible by 4, the last bytes were not looking like an endianness problem because they were in the wrong order but not for example 0 - which would be the case for an endianness problem with 32 bit registers. At the end, it turned out to be the way how i2c_write tried to add the bytes to the send registers. Each 32 bit register was used similar to a shift register - shifting the various bytes up the register while the next one is added to the least significant byte. But the I2C controller expects the first byte of the transmission in the least significant byte of the first register. And the last byte (assuming it is a 16 byte transfer) is expected in the most significant byte of the fourth register. While doing these tests, it was also observed that the count byte was missing from the SMBus Block Writes. The driver just removed them from the data->block (from the I2C subsystem). But the I2C controller DOES NOT automatically add this byte - for example by using the configured transmission length. The RTL8239 MCU is not actually an SMBus compliant device. Instead, it expects I2C Block Reads + I2C Block Writes. But according to the already identified bugs in the driver, it was clear that the I2C controller can simply be modified to not send the count byte for I2C_SMBUS_I2C_BLOCK_DATA. The receive part just needs to write the content of the receive buffer to the correct position in data->block. While the on-wire format was now correct, reads were still not possible against the MCU (for the RTL8239 POE chip). It was always timing out because the 2ms were not enough for sending the read request and then receiving the 12 byte answer. These changes were originally submitted to OpenWrt. But there are plans to migrate OpenWrt to the upstream Linux driver. As a result, the pull request was stopped and the changes were redone against this driver. For reasons of transparency: The work on I2C_SMBUS_I2C_BLOCK_DATA support for the RTL8239-MCU was done on RTL931xx. All problems were therefore detected with the patches from Jonas Jelonek [1] and not the vanilla Linux driver. But looking through the code, it seems like these are NOT regressions introduced by the RTL931x patchset. I've picked up Alex Guo's patch [2] to reduce conflicts between pending fixes.
