2025-02-01sh: Migrate to the generic rule for built-in DTBMasahiro Yamada
Commit 654102df2ac2 ("kbuild: add generic support for built-in boot DTBs") introduced generic support for built-in DTBs. Select GENERIC_BUILTIN_DTB when built-in DTB support is enabled. To keep consistency across architectures, this commit also renames CONFIG_USE_BUILTIN_DTB to CONFIG_BUILTIN_DTB, and CONFIG_BUILTIN_DTB_SOURCE to CONFIG_BUILTIN_DTB_NAME.

2025-02-01sh: irq: Use seq_put_decimal_ull_width() for decimal valuesDavid Wang
On a system with n CPUs and m interrupts, there will be n*m decimal values yielded via seq_printf(.."%10u "..) which has significant costs parsing format string and is less efficient than seq_put_decimal_ull_width(). Stress reading /proc/interrupts indicates ~30% performance improvement with this patch.

This bogus stale file was added in commit 101971298be2 ("riscv: add a warning when physical memory address overflows"). It's the old location for what is now 'security/selinux/genheaders'.

2025-01-31Revert "media: uvcvideo: Require entities to have a non-zero unique ID"Thadeu Lima de Souza Cascardo
This reverts commit 3dd075fe8ebbc6fcbf998f81a75b8c4b159a6195. Tomasz has reported that his device, Generalplus Technology Inc. 808 Camera, with ID 1b3f:2002, stopped being detected: $ ls -l /dev/video* zsh: no matches found: /dev/video* [ 7.230599] usb 3-2: Found multiple Units with ID 5 This particular device is non-compliant, having both the Output Terminal and Processing Unit with ID 5. uvc_scan_fallback, though, is able to build a chain. However, when media elements are added and uvc_mc_create_links call uvc_entity_by_id, it will get the incorrect entity, media_create_pad_link will WARN, and it will fail to register the entities. In order to reinstate support for such devices in a timely fashion, reverting the fix for these warnings is appropriate. A proper fix that considers the existence of such non-compliant devices will be submitted in a later development cycle.

Due to the fact that runtime const ELF sections are named without a leading period or double underscore, the RSTRIP logic that removes the static RELA sections from vmlinux fails to identify them. This results in a situation like below, where some sections that were supposed to get removed are left behind. [Nr] Name Type Address Off Size ES Flg Lk Inf Al [58] runtime_shift_d_hash_shift PROGBITS ffffffff83500f50 2900f50 000014 00 A 0 0 1 [59] .relaruntime_shift_d_hash_shift RELA 0000000000000000 55b6f00 000078 18 I 70 58 8 [60] runtime_ptr_dentry_hashtable PROGBITS ffffffff83500f68 2900f68 000014 00 A 0 0 1 [61] .relaruntime_ptr_dentry_hashtable RELA 0000000000000000 55b6f78 000078 18 I 70 60 8 [62] runtime_ptr_USER_PTR_MAX PROGBITS ffffffff83500f80 2900f80 000238 00 A 0 0 1 [63] .relaruntime_ptr_USER_PTR_MAX RELA 0000000000000000 55b6ff0 000d50 18 I 70 62 8 So tweak the match expression to strip all sections starting with .rel.

2025-01-31cifs: Fix parsing native symlinks directory/file typePali Rohár
As SMB protocol distinguish between symlink to directory and symlink to file, add some mechanism to disallow resolving incompatible types. When SMB symlink is of the directory type, ensure that its target path ends with slash. This forces Linux to not allow resolving such symlink to file. And when SMB symlink is of the file type and its target path ends with slash then returns an error as such symlink is unresolvable. Such symlink always points to invalid location as file cannot end with slash. As POSIX server does not distinguish between symlinks to file and symlink directory, do not apply this change for symlinks from POSIX SMB server. For POSIX SMB servers, this change does nothing. This mimics Windows behavior of native SMB symlinks. Signed-off-by: Pali Rohár <pali@kernel.org> Signed-off-by: Steve French <stfrench@microsoft.com>

2025-01-31cifs: Add support for creating WSL-style symlinksPali Rohár
This change implements support for creating new symlink in WSL-style by Linux cifs client when -o reparse=wsl mount option is specified. WSL-style symlink uses reparse point with tag IO_REPARSE_TAG_LX_SYMLINK and symlink target location is stored in reparse buffer in UTF-8 encoding prefixed by 32-bit flags. Flags bits are unknown, but it was observed that WSL always sets flags to value 0x02000000. Do same in Linux cifs client. New symlinks would be created in WSL-style only in case the mount option -o reparse=wsl is specified, which is not by default. So default CIFS mounts are not affected by this change.

2025-01-31smb3: add support for IAKerbSteve French
There are now more servers which advertise support for IAKerb (passthrough Kerberos authentication via proxy). IAKerb is a public extension industry standard Kerberos protocol that allows a client without line-of-sight to a Domain Controller to authenticate. There can be cases where we would fail to mount if the server only advertises the OID for IAKerb in SPNEGO/GSSAPI. Add code to allow us to still upcall to userspace in these cases to obtain the Kerberos ticket. Signed-off-by: Steve French <stfrench@microsoft.com>
2025-01-31cifs: Fix struct FILE_ALL_INFOPali Rohár
struct FILE_ALL_INFO for level 263 (0x107) used by QPathInfo does not have any IndexNumber, AccessFlags, IndexNumber1, CurrentByteOffset, Mode or AlignmentRequirement members. So remove all of them. Also adjust code in move_cifs_info_to_smb2() function which converts struct FILE_ALL_INFO to struct smb2_file_all_info. Fixed content of struct FILE_ALL_INFO was verified that is correct against: * [MS-CIFS] section 2.2.8.3.10 SMB_QUERY_FILE_ALL_INFO * Samba server implementation of trans2 query file/path for level 263 * Packet structure tests against Windows SMB servers This change fixes CIFSSMBQFileInfo() and CIFSSMBQPathInfo() functions which directly copy received FILE_ALL_INFO network buffers into kernel structures of FILE_ALL_INFO type. struct FILE_ALL_INFO is the response structure returned by the SMB server. So the incorrect definition of this structure can lead to returning bogus information in stat() call. Signed-off-by: Pali Rohár <pali@kernel.org> Signed-off-by: Steve French <stfrench@microsoft.com>
2025-01-31cifs: Add support for creating NFS-style symlinksPali Rohár
CIFS client is currently able to parse NFS-style symlinks, but is not able to create them. This functionality is useful when the mounted SMB share is used also by Windows NFS server (on Windows Server 2012 or new). It allows interop of symlinks between SMB share mounted by Linux CIFS client and same export from Windows NFS server mounted by some NFS client. New symlinks would be created in NFS-style only in case the mount option -o reparse=nfs is specified, which is not by default. So default CIFS mounts are not affected by this change.

2025-01-31block: force noio scope in blk_mq_freeze_queueChristoph Hellwig
When block drivers or the core block code perform allocations with a frozen queue, this could try to recurse into the block device to reclaim memory and deadlock. Thus all allocations done by a process that froze a queue need to be done without __GFP_IO and __GFP_FS. Instead of tying to track all of them down, force a noio scope as part of freezing the queue. Note that nvme is a bit of a mess here due to the non-owner freezes, and they will be addressed separately.

2025-01-30hexagon: Fix unbalanced spinlock in die()Lin Yujun
die executes holding the spinlock of &die.lock and unlock it after printing the oops message. However in the code if the notify_die() returns NOTIFY_STOP , die() exit with returning 1 but never unlocked the spinlock. Fix this by adding spin_unlock_irq(&die.lock) before returning.
