[PATCH v2 4/9] ext4: fix slab-out-of-bounds in ext4_mb_find_good_group_avg_frag_lists()

by Baokun Li

We can trigger a slab-out-of-bounds with the following commands: mkfs.ext4 -F /dev/$disk 10G mount /dev/$disk /tmp/test echo 2147483647 > /sys/fs/ext4/$disk/mb_group_prealloc echo test > /tmp/test/file && sync ================================================================== BUG: KASAN: slab-out-of-bounds in ext4_mb_find_good_group_avg_frag_lists+0x8a/0x200 [ext4] Read of size 8 at addr ffff888121b9d0f0 by task kworker/u2:0/11 CPU: 0 PID: 11 Comm: kworker/u2:0 Tainted: GL 6.7.0-next-20240118 #521 Call Trace: dump_stack_lvl+0x2c/0x50 kasan_report+0xb6/0xf0 ext4_mb_find_good_group_avg_frag_lists+0x8a/0x200 [ext4] ext4_mb_regular_allocator+0x19e9/0x2370 [ext4] ext4_mb_new_blocks+0x88a/0x1370 [ext4] ext4_ext_map_blocks+0x14f7/0x2390 [ext4] ext4_map_blocks+0x569/0xea0 [ext4] ext4_do_writepages+0x10f6/0x1bc0 [ext4] [...] ================================================================== The flow of issue triggering is as follows: // Set s_mb_group_prealloc to 2147483647 via sysfs ext4_mb_new_blocks ext4_mb_normalize_request ext4_mb_normalize_group_request ac->ac_g_ex.fe_len = EXT4_SB(sb)->s_mb_group_prealloc ext4_mb_regular_allocator ext4_mb_choose_next_group ext4_mb_choose_next_group_best_avail mb_avg_fragment_size_order order = fls(len) - 2 = 29 ext4_mb_find_good_group_avg_frag_lists frag_list = &sbi->s_mb_avg_fragment_size[order] if (list_empty(frag_list)) // Trigger SOOB!

Add a new attr_id attr_clusters_in_group with values in the range [0, sbi->s_clusters_per_group] and declare mb_group_prealloc as that type to fix the issue.

[PATCH] powerpc: xor_vmx: Add '-mhard-float' to CFLAGS

by Nathan Chancellor

arch/powerpc/lib/xor_vmx.o is built with '-msoft-float' (from the main powerpc Makefile) and '-maltivec' (from its CFLAGS), which causes an error when building with clang after a recent change in main: error: option '-msoft-float' cannot be specified with '-maltivec' make[6]: *** [scripts/Makefile.build:243: arch/powerpc/lib/xor_vmx.o] Error 1 Explicitly add '-mhard-float' before '-maltivec' in xor_vmx.o's CFLAGS to override the previous inclusion of '-msoft-float' (as the last option wins), which matches how other areas of the kernel use '-maltivec', such as AMDGPU.

[PATCH 1/2] driver core: Clear FWNODE_FLAG_NOT_DEVICE when a device is added

by Herve Codina

Since commit 1a50d9403fb9 ("treewide: Fix probing of devices in DT overlays"), when using device-tree overlays, the FWNODE_FLAG_NOT_DEVICE is set on each overlay nodes. When an overlay contains a node related to a bus (i2c for instance) and its children nodes representing i2c devices, the flag is cleared for the bus node by the OF notifier but the "standard" probe sequence takes place (the same one is performed without an overlay) for the bus and children devices are created simply by walking the children DT nodes without clearing the FWNODE_FLAG_NOT_DEVICE flag for these devices. Clear the FWNODE_FLAG_NOT_DEVICE when the device is added, no matter if an overlay is used or not.

Regression with Lenovo ThinkPad Compact USB Keyboard

by Raphaël Halimi

Dear developers, (sorry for the long CC list, it looks quite long to me, but I tried to follow the issue reporting guide as closely as possible) Since patches [1], [2] and [3] were applied to the kernel, there is a regression with Lenovo ThinkPad Compact USB Keyboard (old model, not II). [1] https://github.com/torvalds/linux/commit/46a0a2c96f0f47628190f122c2e3d879e5… [2] https://github.com/torvalds/linux/commit/2f2bd7cbd1d1548137b351040dc4e037d1… [3] https://github.com/torvalds/linux/commit/43527a0094c10dfbf0d5a2e7979395a38d… The regression is that a middle click is performed when releasing middle button after wheel emulation. The bug appears randomly, it can be after 5 minutes or 1 hour of keyboard usage, and can only be worked around by unplugging/re-plugging the keyboard. (I ended up resorting to simulate an unplug/replug, with a script which echoes 0 then 1 to /sys/bus/usb/devices/<id>/authorized, since I was afraid to damage the Micro-USB outlet by physically unplugging/re-plugging too much). Those spurious clicks are very annoying, since they can open links in new tabs when scrolling in Firefox, or pasting text when scrolling in terminals, or other unwanted stuff. I witnessed it with latest kernels (Debian unstable) as well as stable kernels (Debian 12 Bookworm, stable). On Debian Stable, the last working kernel was 5.10.127, the regression appeared in 5.10.136 (i read all changelogs on kernel.org between those two releases but couldn't find anything about hid-lenovo, so I can't tell exactly in which release the regression appeared, Debian upgraded directly from .127 to .136). I reported it in Debian [4], and apparently I'm not the only person suffering from it [5]. [4] https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1058758#32 [5] https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1058758#42 I would understand that such bugs would end up in a development kernel like the ones provided by Debian Unstable, but not with stable kernels like the ones provided by Debian Stable.

[PATCH v3] usb: typec: altmodes/displayport: create sysfs nodes as driver's default device attribute group

by RD Babiera

The DisplayPort driver's sysfs nodes may be present to the userspace before typec_altmode_set_drvdata() completes in dp_altmode_probe. This means that a sysfs read can trigger a NULL pointer error by deferencing dp->hpd in hpd_show or dp->lock in pin_assignment_show, as dev_get_drvdata() returns NULL in those cases. Remove manual sysfs node creation in favor of adding attribute group as default for devices bound to the driver. The ATTRIBUTE_GROUPS() macro is not used here otherwise the path to the sysfs nodes is no longer compliant with the ABI.

[PATCH v2] usb: typec: tpcm: Fix PORT_RESET behavior for self powered devices

by Badhri Jagan Sridharan

While commit 69f89168b310 ("usb: typec: tpcm: Fix issues with power being removed during reset") fixes the boot issues for bus powered devices such as LibreTech Renegade Elite/Firefly, it trades off the CC pins NOT being Hi-Zed during errory recovery (i.e PORT_RESET) for devices which are NOT bus powered(a.k.a self powered). This change Hi-Zs the CC pins only for self powered devices, thus preventing brown out for bus powered devices Adhering to spec is gaining more importance due to the Common charger initiative enforced by the European Union. Quoting from the spec: 4.5.2.2.2.1 ErrorRecovery State Requirements The port shall not drive VBUS or VCONN, and shall present a high-impedance to ground (above zOPEN) on its CC1 and CC2 pins. Hi-Zing the CC pins is the inteded behavior for PORT_RESET. CC pins are set to default state after tErrorRecovery in PORT_RESET_WAIT_OFF. 4.5.2.2.2.2 Exiting From ErrorRecovery State A Sink shall transition to Unattached.SNK after tErrorRecovery. A Source shall transition to Unattached.SRC after tErrorRecovery.

[PATCH v2 0/7] sparc32: build fixes for all{yes,mod}config builds

by Sam Ravnborg via B4 Relay

This is a small set of patches that address build breakage with allyesconfig / allmodconfig. This solves some, but not all, build breakage. The parport fix depends on the previous patch, the rest are independent fixes. With v2 there is a extra patch that drops ZONE_DMA support. It does not fix any build failure, but a nice cleanup.

Similar for a handful of other symbols. Any hint how to get rid of them would be nice. I have tried to add the prototype to asm-prototypes.h with no luck. On top of this the link fails, but I assume this the kernel that grows too big which is no surprise. - Link to v1: https://lore.kernel.org/r/20240223-sam-fix-sparc32-all-builds-v1-0-5c60fd5c… --- Sam Ravnborg (7): sparc32: Use generic cmpdi2/ucmpdi2 variants sparc32: Fix build with trapbase mtd: maps: sun_uflash: Declare uflash_devinit static sparc32: Do not select ZONE_DMA sparc32: Do not select GENERIC_ISA_DMA sparc32: Fix parport build with sparc32 sparc32: Fix section mismatch in leon_pci_grpci arch/sparc/Kconfig | 7 +- arch/sparc/include/asm/parport.h | 259 +----------------------------------- arch/sparc/include/asm/parport_64.h | 256 +++++++++++++++++++++++++++++++++++ arch/sparc/kernel/irq_32.c | 6 +- arch/sparc/kernel/kernel.h | 8 +- arch/sparc/kernel/kgdb_32.c | 4 +- arch/sparc/kernel/leon_pci_grpci1.c | 2 +- arch/sparc/kernel/leon_pci_grpci2.c | 2 +- arch/sparc/kernel/leon_smp.c | 6 +- arch/sparc/kernel/setup_32.c | 4 +- arch/sparc/lib/Makefile | 4 +- arch/sparc/lib/cmpdi2.c | 28 ---- arch/sparc/lib/ucmpdi2.c | 20 --- arch/sparc/mm/srmmu.c | 1 - drivers/mtd/maps/sun_uflash.c | 2 +- 15 files changed, 284 insertions(+), 325 deletions(-) --- base-commit: 626db6ee8ee1edac206610db407114aa83b53fd3 change-id: 20240223-sam-fix-sparc32-all-builds-0a0403d6e1b3 Best regards, -- Sam Ravnborg <sam(a)ravnborg.org>
