[PATCH v1] Bluetooth: hci_qca: Fix SSR unable to wake up bug

by Shuai Zhang

During SSR data collection period, the processing of hw_error events must wait until SSR data Collected or the timeout before it can proceed. The wake_up_bit function has been added to address the issue where hw_error events could only be processed after the timeout. The timeout unit has been changed from jiffies to milliseconds (ms).

[PATCH RFC] ext4: add i_data_sem protection in ext4_destroy_inline_data_nolock()

by Alexey Nepomnyashih

Fix a race between inline data destruction and block mapping. The function ext4_destroy_inline_data_nolock() changes the inode data layout by clearing EXT4_INODE_INLINE_DATA and setting EXT4_INODE_EXTENTS. At the same time, another thread may execute ext4_map_blocks(), which tests EXT4_INODE_EXTENTS to decide whether to call ext4_ext_map_blocks() or ext4_ind_map_blocks(). Without i_data_sem protection, ext4_ind_map_blocks() may receive inode with EXT4_INODE_EXTENTS flag and triggering assert. kernel BUG at fs/ext4/indirect.c:546!

[PATCH 6.6.y] usb: gadget: f_fs: Fix epfile null pointer access after ep enable.

by guhuinan

From: Owen Gu <guhuinan(a)xiaomi.com> [ Upstream commit cfd6f1a7b42f ("usb: gadget: f_fs: Fix epfile null pointer access after ep enable.") ] A race condition occurs when ffs_func_eps_enable() runs concurrently with ffs_data_reset(). The ffs_data_clear() called in ffs_data_reset() sets ffs->epfiles to NULL before resetting ffs->eps_count to 0, leading to a NULL pointer dereference when accessing epfile->ep in ffs_func_eps_enable() after successful usb_ep_enable(). The ffs->epfiles pointer is set to NULL in both ffs_data_clear() and ffs_data_close() functions, and its modification is protected by the spinlock ffs->eps_lock. And the whole ffs_func_eps_enable() function is also protected by ffs->eps_lock. Thus, add NULL pointer handling for ffs->epfiles in the ffs_func_eps_enable() function to fix issues Signed-off-by: Owen Gu <guhuinan(a)xiaomi.com> Link: https://lore.kernel.org/r/20250915092907.17802-1-guhuinan@xiaomi.com Signed-off-by: Greg Kroah-Hartman <gregkh(a)linuxfoundation.org> --- drivers/usb/gadget/function/f_fs.c | 8 +++++++- 1 file changed, 7 insertions(+), 1 deletion(-) diff --git a/drivers/usb/gadget/function/f_fs.c b/drivers/usb/gadget/function/f_fs.c index 08a251df20c4..04058261cdd0 100644 --- a/drivers/usb/gadget/function/f_fs.c +++ b/drivers/usb/gadget/function/f_fs.c @@ -2407,7 +2407,12 @@ static int ffs_func_eps_enable(struct ffs_function *func) ep = func->eps; epfile = ffs->epfiles; count = ffs->eps_count; - while(count--) { + if (!epfile) { + ret = -ENOMEM; + goto done; + } + + while (count--) { ep->ep->driver_data = ep; ret = config_ep_by_speed(func->gadget, &func->function, ep->ep); @@ -2431,6 +2436,7 @@ static int ffs_func_eps_enable(struct ffs_function *func) } wake_up_interruptible(&ffs->wait); +done: spin_unlock_irqrestore(&func->ffs->eps_lock, flags); return ret; -- 2.43.0
