While we're here, we refactor the function to be more readable and add some additional documentation.

[PATCH] arm64: tls: Fix context-switching of tpidrro_el0 when kpti is enabled

by Will Deacon

Commit 18011eac28c7 ("arm64: tls: Avoid unconditional zeroing of tpidrro_el0 for native tasks") tried to optimise the context switching of tpidrro_el0 by eliding the clearing of the register when switching to a native task with kpti enabled, on the erroneous assumption that the kpti trampoline entry code would already have taken care of the write. Although the kpti trampoline does zero the register on entry from a native task, the check in tls_thread_switch() is on the *next* task and so we can end up leaving a stale, non-zero value in the register if the previous task was 32-bit. Drop the broken optimisation and zero tpidrro_el0 unconditionally when switching to a native 64-bit task.

[PATCH net v2] netfilter: ipset: add missing range check in bitmap_ip_uadt

by Jeongjun Park

When tb[IPSET_ATTR_IP_TO] is not present but tb[IPSET_ATTR_CIDR] exists, the values of ip and ip_to are slightly swapped. Therefore, the range check for ip should be done later, but this part is missing and it seems that the vulnerability occurs. So we should add missing range checks and remove unnecessary range checks.

[PATCH] drm/panthor: Fix memory leak in panthor_ioctl_group_create()

by Jann Horn

When bailing out due to group_priority_permit() failure, the queue_args need to be freed. Fix it by rearranging the function to use the goto-on-error pattern, such that the success case flows straight without indentation while error cases jump forward to cleanup. Cc: stable(a)vger.kernel.org Fixes: 5f7762042f8a ("drm/panthor: Restrict high priorities on group_create") Signed-off-by: Jann Horn <jannh(a)google.com> --- testcase: ``` #include <err.h> #include <fcntl.h> #include <stddef.h> #include <sys/ioctl.h> #include <drm/panthor_drm.h> #define SYSCHK(x) ({ \ typeof(x) __res = (x); \ if (__res == (typeof(x))-1) \ err(1, "SYSCHK(" #x ")"); \ __res; \ }) #define GPU_PATH "/dev/dri/by-path/platform-fb000000.gpu-card" int main(void) { int fd = SYSCHK(open(GPU_PATH, O_RDWR)); while (1) { struct drm_panthor_queue_create qc[16] = {}; struct drm_panthor_group_create gc = { .queues = { .stride = sizeof(struct drm_panthor_queue_create), .count = 16, .array = (unsigned long)qc }, .priority = PANTHOR_GROUP_PRIORITY_HIGH+1/*invalid*/ }; ioctl(fd, DRM_IOCTL_PANTHOR_GROUP_CREATE, &gc); } } ``` I have tested that without this patch, after running the testcase for a few seconds and then manually killing it, 2G of RAM in kmalloc-128 have been leaked. With the patch applied, the memory leak is gone. (By the way, get_maintainer.pl suggests that I also send this patch to the general DRM maintainers and the DRM-misc maintainers; looking at MAINTAINERS, it looks like it is normal that the general DRM maintainers are listed for everything under drivers/gpu/, but DRM-misc has exclusion rules for a bunch of drivers but not panthor. I don't know if that is intentional.) --- drivers/gpu/drm/panthor/panthor_drv.c | 11 ++++++----- 1 file changed, 6 insertions(+), 5 deletions(-) diff --git a/drivers/gpu/drm/panthor/panthor_drv.c b/drivers/gpu/drm/panthor/panthor_drv.c index c520f156e2d73f7e735f8bf2d6d8e8efacec9362..815c23cff25f305d884e8e3e263fa22888f7d5ce 100644 --- a/drivers/gpu/drm/panthor/panthor_drv.c +++ b/drivers/gpu/drm/panthor/panthor_drv.c @@ -1032,14 +1032,15 @@ static int panthor_ioctl_group_create(struct drm_device *ddev, void *data, ret = group_priority_permit(file, args->priority); if (ret) - return ret; + goto out; ret = panthor_group_create(pfile, args, queue_args); - if (ret >= 0) { - args->group_handle = ret; - ret = 0; - } + if (ret < 0) + goto out; + args->group_handle = ret; + ret = 0; +out: kvfree(queue_args); return ret; } --- base-commit: 9f8e716d46c68112484a23d1742d9ec725e082fc change-id: 20241113-panthor-fix-gcq-bailout-2d9ac36590ed -- Jann Horn <jannh(a)google.com>

[PATCH v2] Revert "usb: gadget: composite: fix OS descriptors w_value logic"

by Elson Roy Serrao

From: Michal Vrastil <michal.vrastil(a)hidglobal.com> This reverts commit ec6ce7075ef879b91a8710829016005dc8170f17. Fix installation of WinUSB driver using OS descriptors. Without the fix the drivers are not installed correctly and the property 'DeviceInterfaceGUID' is missing on host side. The original change was based on the assumption that the interface number is in the high byte of wValue but it is in the low byte, instead. Unfortunately, the fix is based on MS documentation which is also wrong. The actual USB request for OS descriptors (using USB analyzer) looks like: Offset 0 1 2 3 4 5 6 7 0x000 C1 A1 02 00 05 00 0A 00 C1: bmRequestType (device to host, vendor, interface) A1: nas magic number 0002: wValue (2: nas interface) 0005: wIndex (5: get extended property i.e. nas interface GUID) 008E: wLength (142) The fix was tested on Windows 10 and Windows 11.

[PATCH v2 2/8] serial: sh-sci: Check if TX data was written to device in .tx_empty()

by Claudiu

From: Claudiu Beznea <claudiu.beznea.uj(a)bp.renesas.com> On the Renesas RZ/G3S, when doing suspend to RAM, the uart_suspend_port() is called. The uart_suspend_port() calls 3 times the struct uart_port::ops::tx_empty() before shutting down the port. According to the documentation, the struct uart_port::ops::tx_empty() API tests whether the transmitter FIFO and shifter for the port is empty. The Renesas RZ/G3S SCIFA IP reports the number of data units stored in the transmit FIFO through the FDR (FIFO Data Count Register). The data units in the FIFOs are written in the shift register and transmitted from there. The TEND bit in the Serial Status Register reports if the data was transmitted from the shift register. In the previous code, in the tx_empty() API implemented by the sh-sci driver, it is considered that the TX is empty if the hardware reports the TEND bit set and the number of data units in the FIFO is zero. According to the HW manual, the TEND bit has the following meaning: 0: Transmission is in the waiting state or in progress. 1: Transmission is completed. It has been noticed that when opening the serial device w/o using it and then switch to a power saving mode, the tx_empty() call in the uart_port_suspend() function fails, leading to the "Unable to drain transmitter" message being printed on the console. This is because the TEND=0 if nothing has been transmitted and the FIFOs are empty. As the TEND=0 has double meaning (waiting state, in progress) we can't determined the scenario described above. Add a software workaround for this. This sets a variable if any data has been sent on the serial console (when using PIO) or if the DMA callback has been called (meaning something has been transmitted). Fixes: 73a19e4c0301 ("serial: sh-sci: Add DMA support.")
