[PATCH 6.1 V2] cifs: use origin fullpath for automounts

by Andrew Paniakin

From: Paulo Alcantara <pc(a)cjr.nz> commit 7ad54b98fc1f141cfb70cfe2a3d6def5a85169ff upstream. Use TCP_Server_Info::origin_fullpath instead of cifs_tcon::tree_name when building source paths for automounts as it will be useful for domain-based DFS referrals where the connections and referrals would get either re-used from the cache or re-created when chasing the dfs link. Signed-off-by: Paulo Alcantara (SUSE) <pc(a)cjr.nz> Signed-off-by: Steve French <stfrench(a)microsoft.com> [apanyaki: backport to v6.1-stable] Signed-off-by: Andrew Paniakin <apanyaki(a)amazon.com> --- Please do not include follow-up fix d5a863a153e9 ("cifs: avoid dup prefix path in dfs_get_automount_devname()"). It works correctly only when all patches applied in a following order: 1. 7ad54b98fc1f1 ("cifs: use origin fullpath for automounts") 2. a1c0d00572fc ("cifs: share dfs connections and supers") (not ported to linux-6.1) 3. d5a863a153e9 ("cifs: avoid dup prefix path in dfs_get_automount_devname()") The reason is that patch a1c0d00572fc ("cifs: share dfs connections and supers") changes origin_fullpath contents from just a namespace root to a full path eg. from '//corp.fsxtest.local/namespace/' to '//corp.fsxtest.local/namespace/folderA/fs1-folder/'. But the prefix path '/folderA/' is also stored in a cifs superblock info and it was copied twice. With patch d5a863a153e9 ("cifs: avoid dup prefix path in dfs_get_automount_devname()") prepath string from superblock info is not used in path construction and result is correct. But the patch a1c0d00572fc ("cifs: share dfs connections and supers") was not ported to linux-6.1, probably because it's a part of huge cifs driver update series merged in linux-6.2, not just a bug fix. So if we apply patches in following order: 1. 7ad54b98fc1f1 ("cifs: use origin fullpath for automounts") 2. d5a863a153e9 ("cifs: avoid dup prefix path in dfs_get_automount_devname()") then constructed fullpath will be '//corp.fsxtest.local/namespace/fs1-folder/' instead of '//corp.fsxtest.local/namespace/folderA/fs1-folder/' because prefix path was not copied from the superblock info. Changelog: v2: - added CONFIG_CIFS_DFS_UPCALL wrapper to fix build issue [1] v1: (updates made to upstream version of this patch) - set_dest_addr() converts DFS address to sockaddr differently: in kernel 6.1 dns_resolve_server_name_to_ip() returns a string which needs to be converted to sockaddr with cifs_convert_address(). - removed hunk to init tmp.leaf_fullpath, it was introduced later in a1c0d00572fc ("cifs: share dfs connections and supers") - __build_path_from_dentry_optional_prefix() and dfs_get_automount_devname() functions were added to fs/smb/client/cifsproto.h instead of fs/cifs/dfs.h as it doesn't exist in 6.1 - Link to v1: https://lore.kernel.org/all/20240713031147.20332-1-apanyaki@amazon.com/ Testing: 1. tested that these steps do not work without this backport and work with it: - mount DFS namespace root: mount -t cifs -o cred=/mnt/creds,noserverino //corp.fsxtest.local - shutdown the namespace server that is in use - access DFS link (triggers automount): ls /mnt/dfs-namespace/fs1-folder Reported verbose logs which demonstrate backport correctness in regression ML thread [2]. 2. build kernel with debug options listed in the patch submission checklist[3], executed cifs test suite of the xfstests [4], no errors. 3. confirmed compilation works with all y/m/n combinations for CONFIG_CIFS and CONFIG_CIFS_DFS_UPCALL. 4. confirmed allmodconfig and allnoconfig cross-compilation works on arm, arm64, mips, powerpc, risc.

From: Daniel Schaefer <dhs(a)frame.work> [ Upstream commit d83c45aeec9b223fe6db4175e9d1c4f5699cc37a ] Load the cros_ec_lpc driver based on a Framework FRMWC004 ACPI device, which mirrors GOOG0004, but also applies npcx quirks for Framework systems. Matching on ACPI will let us avoid having to change the SMBIOS match rules again and again. Cc: Tzung-Bi Shih <tzungbi(a)kernel.org> Cc: linux(a)frame.work Cc: Dustin L.
