9p: fix slab cache name creation for real

2024-11-17T13:58:08Z

commit a360f311f57a36e96d88fa8086b749159714dcd2 upstream. This was attempted by using the dev_name in the slab cache name, but as Omar Sandoval pointed out, that can be an arbitrary string, eg something like "/dev/root". Which in turn trips verify_dirent_name(), which fails if a filename contains a slash. So just make it use a sequence counter, and make it an atomic_t to avoid any possible races or locking issues.

fs: Fix uninitialized value issue in from_kuid and from_kgid

2024-11-17T13:58:08Z

[ Upstream commit 15f34347481648a567db67fb473c23befb796af5 ] ocfs2_setattr() uses attr->ia_mode, attr->ia_uid and attr->ia_gid in a trace point even though ATTR_MODE, ATTR_UID and ATTR_GID aren't set. Initialize all fields of newattrs to avoid uninitialized variables, by checking if ATTR_MODE, ATTR_UID, ATTR_GID are initialized, otherwise 0.

powerpc/powernv: Free name on error in opal_event_init()

2024-11-17T13:58:08Z

[ Upstream commit cf8989d20d64ad702a6210c11a0347ebf3852aa7 ] In opal_event_init() if request_irq() fails name is not freed, leading to a memory leak. The code only runs at boot time, there's no way for a user to trigger it, so there's no security impact. Fix the leak by freeing name in the error path.

sound: Make CONFIG_SND depend on INDIRECT_IOMEM instead of UML

2024-11-17T13:58:08Z

[ Upstream commit ad6639f143a0b42d7fb110ad14f5949f7c218890 ] When building for the UM arch and neither INDIRECT_IOMEM=y, nor HAS_IOMEM=y is selected, it will fall back to the implementations from asm-generic/io.h for IO memcpy. But these fall-back functions just do a memcpy. So, instead of depending on UML, add dependency on 'HAS_IOMEM || INDIRECT_IOMEM'.

bpf: use kvzmalloc to allocate BPF verifier environment

2024-11-17T13:58:08Z

[ Upstream commit 434247637c66e1be2bc71a9987d4c3f0d8672387 ] The kzmalloc call in bpf_check can fail when memory is very fragmented, which in turn can lead to an OOM kill. Use kvzmalloc to fall back to vmalloc when memory is too fragmented to allocate an order 3 sized bpf verifier environment. Admittedly this is not a very common case, and only happens on systems where memory has already been squeezed close to the limit, but this does not seem like much of a hot path, and it's a simple enough fix.

HID: multitouch: Add quirk for HONOR MagicBook Art 14 touchpad

2024-11-17T13:58:08Z

[ Upstream commit 7a5ab8071114344f62a8b1e64ed3452a77257d76 ] The behavior of HONOR MagicBook Art 14 touchpad is not consistent after reboots, as sometimes it reports itself as a touchpad, and sometimes as a mouse. Similarly to GLO-GXXX it is possible to call MT_QUIRK_FORCE_GET_FEATURE as a workaround to force set feature in mt_set_input_mode() for such special touchpad device.
