2025-07-28rv: Fix wrong type cast in reactors_show() and monitor_reactor_show()Nam Cao
Argument 'p' of reactors_show() and monitor_reactor_show() is not a pointer to struct rv_reactor, it is actually a pointer to the list_head inside struct rv_reactor. Therefore it's wrong to cast 'p' to struct rv_reactor *. This wrong type cast has been there since the beginning. But it still worked because the list_head was the first field in struct rv_reactor_def. This is no longer true since commit 3d3c376118b5 ("rv: Merge struct rv_reactor_def into struct rv_reactor") moved the list_head, and this wrong type cast became a functional problem. Properly use container_of() instead.

Memory allocated with drmm_kzalloc() should not be freed using kfree(), as it is managed by the DRM subsystem. The memory will be automatically freed when the associated drm_device is released. These 3 group pointers are allocated using drmm_kzalloc() in hw_engine_group_alloc(), so they don't require manual deallocation.

The -P option is used to set priority of osnoise and timerlat threads. Extend the test for -P with --on-threshold calling a script that looks for running timerlat threads and checks if their priority is set correctly. As --on-threshold is only supported by timerlat at the moment, this is only implemented there so far.

2025-07-28ALSA: scarlett2: Add retry on -EPROTO from scarlett2_usb_tx()Geoffrey D. Bennett
During communication with Focusrite Scarlett Gen 2/3/4 USB audio interfaces, -EPROTO is sometimes returned from scarlett2_usb_tx(), snd_usb_ctl_msg() which can cause initialisation and control operations to fail intermittently. This patch adds up to 5 retries in scarlett2_usb(), with a delay starting at 5ms and doubling each time. This follows the same approach as the fix for usb_set_interface() in endpoint.c (commit f406005e162b ("ALSA: usb-audio: Add retry on -EPROTO from usb_set_interface()")), which resolved similar -EPROTO issues during device initialisation, and is the same approach as in fcp.c:fcp_usb().

2025-07-28i2c: core: Fix double-free of fwnode in i2c_unregister_device()Hans de Goede
Before commit df6d7277e552 ("i2c: core: Do not dereference fwnode in struct device"), i2c_unregister_device() only called fwnode_handle_put() on of_node-s in the form of calling of_node_put(client->dev.of_node). But after this commit the i2c_client's fwnode now unconditionally gets fwnode_handle_put() on it. When the i2c_client has no primary (ACPI / OF) fwnode but it does have a software fwnode, the software-node will be the primary node and fwnode_handle_put() will put() it. But for the software fwnode device_remove_software_node() will also put() it leading to a double free: [ 82.665598] ------------[ cut here ]------------ [ 82.665609] refcount_t: underflow; use-after-free.

Add support for the Texas Instruments INA228 Ultra-Precise Power/Energy/Charge Monitor. The INA228 is very similar to the INA238 but offers four bits of extra precision in the temperature, voltage and current measurement fields. It also supports energy and charge monitoring, the latter of which is not supported through this patch. While it seems in the datasheet that some constants such as LSB values differ between the 228 and the 238, they differ only for those registers where four bits of precision have been added and they differ by a factor of 16 (VBUS, VSHUNT, DIETEMP, CURRENT). Therefore, the INA238 constants are still applicable with regard to the bit of the same significance.

2025-07-27cifs: Add support for creating reparse points over SMB1Pali Rohár
SMB1 already supports querying reparse points and detecting types of symlink, fifo, socket, block and char. This change implements the missing part - ability to create a new reparse points over SMB1. This includes everything which SMB2+ already supports: - native SMB symlinks and sockets - NFS style of special files (symlinks, fifos, sockets, char/block devs) - WSL style of special files (symlinks, fifos, sockets, char/block devs) Attaching a reparse point to an existing file or directory is done via SMB1 SMB_COM_NT_TRANSACT/NT_TRANSACT_IOCTL/FSCTL_SET_REPARSE_POINT command and implemented in a new cifs_create_reparse_inode() function. This change introduce a new callback ->create_reparse_inode() which creates a new reperse point file or directory and returns inode. For SMB1 it is provided via that new cifs_create_reparse_inode() function. Existing reparse.c code was only slightly updated to call new protocol callback ->create_reparse_inode() instead of hardcoded SMB2+ function. This make the whole reparse.c code to work with every SMB dialect. The original callback ->create_reparse_symlink() is not needed anymore as the implementation of new create_reparse_symlink() function is dialect agnostic too. So the link.c code was updated to call that function directly (and not via callback). Signed-off-by: Pali Rohár <pali@kernel.org> Signed-off-by: Steve French <stfrench@microsoft.com>

2025-07-27cifs: Fix calling CIFSFindFirst() for root path without msearchPali Rohár
To query root path (without msearch wildcard) it is needed to send pattern '\' instead of '' (empty string). This allows to use CIFSFindFirst() to query information about root path which is being used in followup changes. This change fixes the stat() syscall called on the root path on the mount. It is because stat() syscall uses the cifs_query_path_info() function and it can fallback to the CIFSFindFirst() usage with msearch=false.

However, if a directory is actively accessed, it should not be chosen to expire first. This change adds a new last_access_time field to cfid and uses that to decide expiry of the cfid.

2025-07-27cifs: reset iface weights when we cannot find a candidateShyam Prasad N
We now do a weighted selection of server interfaces when allocating new channels. The weights are decided based on the speed advertised. The fulfilled weight for an interface is a counter that is used to track the interface selection. It should be reset back to zero once all interfaces fulfilling their weight. In cifs_chan_update_iface, this reset logic was missing. As a result when the server interface list changes, the client may not be able to find a new candidate for other channels after all interfaces have been fulfilled.

2025-07-27smb: client: fix netns refcount leak after net_passive changesWang Zhaolong
After commit 5c70eb5c593d ("net: better track kernel sockets lifetime"), kernel sockets now use net_passive reference counting. However, commit 95d2b9f693ff ("Revert "smb: client: fix TCP timers deadlock after rmmod"") restored the manual socket refcount manipulation without adapting to this new mechanism, causing a memory leak. The issue can be reproduced by[1]: 1. Creating a network namespace 2. Mounting and Unmounting CIFS within the namespace 3. Deleting the namespace Some memory leaks may appear after a period of time following step 3. unreferenced object 0xffff9951419f6b00 (size 256): comm "ip", pid 447, jiffies 4294692389 (age 14.730s) hex dump (first 32 bytes): 1b 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................ 00 00 00 00 00 00 00 00 80 77 c2 44 51 99 ff ff .........w.DQ... backtrace: __kmem_cache_alloc_node+0x30e/0x3d0 __kmalloc+0x52/0x120 net_alloc_generic+0x1d/0x30 copy_net_ns+0x86/0x200 create_new_namespaces+0x117/0x300 unshare_nsproxy_namespaces+0x60/0xa0 ksys_unshare+0x148/0x360 __x64_sys_unshare+0x12/0x20 do_syscall_64+0x59/0x110 entry_SYSCALL_64_after_hwframe+0x78/0xe2 ... unreferenced object 0xffff9951442e7500 (size 32): comm "mount.cifs", pid 475, jiffies 4294693782 (age 13.343s) hex dump (first 32 bytes): 40 c5 38 46 51 99 ff ff 18 01 96 42 51 99 ff ff @.8FQ......BQ... 01 00 00 00 6f 00 c5 07 6f 00 d8 07 00 00 00 00 ....o...o....... backtrace: __kmem_cache_alloc_node+0x30e/0x3d0 kmalloc_trace+0x2a/0x90 ref_tracker_alloc+0x8e/0x1d0 sk_alloc+0x18c/0x1c0 inet_create+0xf1/0x370 __sock_create+0xd7/0x1e0 generic_ip_connect+0x1d4/0x5a0 [cifs] cifs_get_tcp_session+0x5d0/0x8a0 [cifs] cifs_mount_get_session+0x47/0x1b0 [cifs] dfs_mount_share+0xfa/0xa10 [cifs] cifs_mount+0x68/0x2b0 [cifs] cifs_smb3_do_mount+0x10b/0x760 [cifs] smb3_get_tree+0x112/0x2e0 [cifs] vfs_get_tree+0x29/0xf0 path_mount+0x2d4/0xa00 __se_sys_mount+0x165/0x1d0 Root cause: When creating kernel sockets, sk_alloc() calls net_passive_inc() for sockets with sk_net_refcnt=0. The CIFS code manually converts kernel sockets to user sockets by setting sk_net_refcnt=1, but doesn't call the corresponding net_passive_dec(). This creates an imbalance in the net_passive counter, which prevents the network namespace from being destroyed when its last user reference is dropped. As a result, the entire namespace and all its associated resources remain allocated. Timeline of patches leading to this issue: - commit ef7134c7fc48 ("smb: client: Fix use-after-free of network namespace.") in v6.12 fixed the original netns UAF by manually managing socket refcounts - commit e9f2517a3e18 ("smb: client: fix TCP timers deadlock after rmmod") in v6.13 attempted to use kernel sockets but introduced TCP timer issues - commit 5c70eb5c593d ("net: better track kernel sockets lifetime") in v6.14-rc5 introduced the net_passive mechanism with sk_net_refcnt_upgrade() for proper socket conversion - commit 95d2b9f693ff ("Revert "smb: client: fix TCP timers deadlock after rmmod"") in v6.15-rc3 reverted to manual refcount management without adapting to the new net_passive changes Fix this by using sk_net_refcnt_upgrade() which properly handles the net_passive counter when converting kernel sockets to user sockets.

Use the newly added of_reserved_mem_region_to_resource() function to handle "memory-region" properties. The error handling is a bit different. "memory-region" is optional, so failed lookup is not an error. But then an error in of_address_to_resource() is treated as an error. However, that distinction is not really important. Either the region is available and usable or it is not. So now, it is just of_reserved_mem_region_to_resource() which is checked for an error.
