2022-08-31usb: dwc3: Do not service EP0 and conndone events if soft disconnectedWesley Cheng2-2/+7
There are some operations that need to be ignored if there is a soft disconnect in progress. This is to avoid having a pending EP0 transfer in progress while attempting to stop active transfers and halting the controller. There were several instances seen where a soft disconnect was able to occur during early link negotiation, i.e. bus reset/conndone, which leads to the conndone handler re-configuring EPs while attempting to halt the controller, as DEP flags are cleared as part of the soft disconnect path. ep0out: cmd 'Start New Configuration' ep0out: cmd 'Set Endpoint Transfer Resource' ep0in: cmd 'Set Endpoint Transfer Resource' ep1out: cmd 'Set Endpoint Transfer Resource' ... event (00030601): Suspend [U3] event (00000101): Reset [U0] ep0out: req ffffff87e5c9e100 length 0/0 zsI ==> 0 event (00000201): Connection Done [U0] ep0out: cmd 'Start New Configuration' ep0out: cmd 'Set Endpoint Transfer Resource' In addition, if a soft disconnect occurs, EP0 events are still allowed to process, however, it will stall/restart during the SETUP phase. The host is still able to query for the DATA phase, leading to a xfernotready(DATA) event. Since none of the SETUP transfer parameters are populated, the xfernotready is treated as a "wrong direction" error, leading to a duplicate stall/restart routine. Add the proper softconnect/connected checks in sequences that are potentially involved during soft disconnect processing.

2022-08-31acl: add vfs_set_acl_prepare()Christian Brauner2-11/+205
Various filesystems store POSIX ACLs on the backing store in their uapi format. Such filesystems need to translate from the uapi POSIX ACL format into the VFS format during i_op->get_acl(). The VFS provides the posix_acl_from_xattr() helper for this task. But the usage of posix_acl_from_xattr() is currently ambiguous. It is intended to transform from a uapi POSIX ACL to the VFS represenation. For example, when retrieving POSIX ACLs for permission checking during lookup or when calling getxattr() to retrieve system.posix_acl_{access,default}. Calling posix_acl_from_xattr() during i_op->get_acl() will map the raw {g,u}id values stored as ACL_{GROUP,USER} entries in the uapi POSIX ACL format into k{g,u}id_t in the filesystem's idmapping and return a struct posix_acl ready to be returned to the VFS for caching and to perform permission checks on. However, posix_acl_from_xattr() is also called during setxattr() for all filesystems that rely on VFS provides posix_acl_{access,default}_xattr_handler. The posix_acl_xattr_set() handler which is used for the ->set() method of posix_acl_{access,default}_xattr_handler uses posix_acl_from_xattr() to translate from the uapi POSIX ACL format to the VFS format so that it can be passed to the i_op->set_acl() handler of the filesystem or for direct caching in case no i_op->set_acl() handler is defined. During setxattr() the {g,u}id values stored as ACL_{GROUP,USER} entries in the uapi POSIX ACL format aren't raw {g,u}id values that need to be mapped according to the filesystem's idmapping. Instead they are {g,u}id values in the caller's idmapping which have been generated during posix_acl_fix_xattr_from_user(). In other words, they are k{g,u}id_t which are passed as raw {g,u}id values abusing the uapi POSIX ACL format (Please note that this type safety violation has existed since the introduction of k{g,u}id_t. Please see [1] for more details.). So when posix_acl_from_xattr() is called in posix_acl_xattr_set() the filesystem idmapping is completely irrelevant. Instead, we abuse the initial idmapping to recover the k{g,u}id_t base on the value stored in raw {g,u}id as ACL_{GROUP,USER} in the uapi POSIX ACL format. We need to clearly distinguish betweeen these two operations as it is really easy to confuse for filesystems as can be seen in ntfs3. In order to do this we factor out make_posix_acl() which takes callbacks allowing callers to pass dedicated methods to generate the correct k{g,u}id_t. This is just an internal static helper which is not exposed to any filesystems but it neatly encapsulates the basic logic of walking through a uapi POSIX ACL and returning an allocated VFS POSIX ACL with the correct k{g,u}id_t values. The posix_acl_from_xattr() helper can then be implemented as a simple call to make_posix_acl() with callbacks that generate the correct k{g,u}id_t from the raw {g,u}id values in ACL_{GROUP,USER} entries in the uapi POSIX ACL format as read from the backing store. For setxattr() we add a new helper vfs_set_acl_prepare() which has callbacks to map the POSIX ACLs from the uapi format with the k{g,u}id_t values stored in raw {g,u}id format in ACL_{GROUP,USER} entries into the correct k{g,u}id_t values in the filesystem idmapping. In contrast to posix_acl_from_xattr() the vfs_set_acl_prepare() helper needs to take the mount idmapping into account. The differences are explained in more detail in the kernel doc for the new functions. In follow up patches we will remove all abuses of posix_acl_from_xattr() for setxattr() operations and replace it with calls to vfs_set_acl_prepare(). The new vfs_set_acl_prepare() helper allows us to deal with the ambiguity in how the POSI ACL uapi struct stores {g,u}id values depending on whether this is a getxattr() or setxattr() operation. This also allows us to remove the posix_acl_setxattr_idmapped_mnt() helper reducing the abuse of the POSIX ACL uapi format to pass values that should be distinct types in {g,u}id values stored as ACL_{GROUP,USER} entries. The removal of posix_acl_setxattr_idmapped_mnt() in turn allows us to re-constify the value parameter of vfs_setxattr() which in turn allows us to avoid the nasty cast from a const void pointer to a non-const void pointer on ovl_do_setxattr(). Ultimately, the plan is to get rid of the type violations completely and never pass the values from k{g,u}id_t as raw {g,u}id in ACL_{GROUP,USER} entries in uapi POSIX ACL format. But that's a longer way to go and this is a preparatory step.

2022-08-31ntfs3: rework xattr handlers and switch to POSIX ACL VFS helpersChristian Brauner2-98/+6
The xattr code in ntfs3 is currently a bit confused. For example, it defines a POSIX ACL i_op->set_acl() method but instead of relying on the generic POSIX ACL VFS helpers it defines its own set of xattr helpers with the consequence that i_op->set_acl() is currently dead code. Switch ntfs3 to rely on the VFS POSIX ACL xattr handlers. Also remove i_op->{g,s}et_acl() methods from symlink inode operations. Symlinks don't support xattrs. This is a preliminary change for the following patches which move handling idmapped mounts directly in posix_acl_xattr_set(). This survives POSIX ACL xfstests.

The same GPIO line can be shared by multiple phys for the coma mode pin. If that is the case then, all the other phys that share the same line will failed to be probed because the access to the gpio line is not non-exclusive. Fix this by making access to the gpio line to be nonexclusive using flag GPIOD_FLAGS_BIT_NONEXCLUSIVE. This allows all the other PHYs to be probed.
