2024-01-08tcp: Revert no longer abort SYN_SENT when receiving some ICMPShachar Kagan
This reverts commit 0a8de364ff7a14558e9676f424283148110384d6. Shachar reported that Vagrant (https://www.vagrantup.com/), which is very popular tool to manage fleet of VMs stopped to work after commit citied in Fixes line. The issue appears while using Vagrant to manage nested VMs. The steps are: * create vagrant file * vagrant up * vagrant halt (VM is created but shut down) * vagrant up - fail Vagrant up stdout: Bringing machine 'player1' up with 'libvirt' provider... ==> player1: Creating shared folders metadata... ==> player1: Starting domain. ==> player1: Domain launching with graphics connection settings... ==> player1: -- Graphics Port: 5900 ==> player1: -- Graphics IP: 127.0.0.1 ==> player1: -- Graphics Password: Not defined ==> player1: -- Graphics Websocket: 5700 ==> player1: Waiting for domain to get an IP address... ==> player1: Waiting for machine to boot. This may take a few minutes... player1: SSH address: 192.168.123.61:22 player1: SSH username: vagrant player1: SSH auth method: private key ==> player1: Attempting graceful shutdown of VM... ==> player1: Attempting graceful shutdown of VM... ==> player1: Attempting graceful shutdown of VM... player1: Guest communication could not be established! This is usually because player1: SSH is not running, the authentication information was changed, player1: or some other networking issue. Vagrant will force halt, if player1: capable. ==> player1: Attempting direct shutdown of domain...

2024-01-08ASoC: mediatek: mt8192: Check existence of dai_name before dereferencingNícolas F. R. A. Prado
Following commit 13f58267cda3 ("ASoC: soc.h: don't create dummy Component via COMP_DUMMY()"), the dai_name field is only populated for dummy components after the card is registered. This causes a null pointer dereference in the mt8192-mt6359 sound card driver's probe function when searching for a dai_name among all the card's dai links. Verify that the dai_name is non-null before passing it to strcmp. While at it, also check that there's at least one codec.

2024-01-08ecryptfs: Reject casefold directory inodesGabriel Krisman Bertazi
Even though it seems to be able to resolve some names of case-insensitive directories, the lack of d_hash and d_compare means we end up with a broken state in the d_cache. Considering it was never a goal to support these two together, and we are preparing to use d_revalidate in case-insensitive filesystems, which would make the combination even more broken, reject any attempt to get a casefolded inode from ecryptfs.

git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs Pull vfs cachefiles updates from Christian Brauner: "This contains improvements for on-demand cachefiles. If the daemon crashes and the on-demand cachefiles fd is unexpectedly closed in-flight requests and subsequent read operations associated with the fd will fail with EIO. This causes issues in various scenarios as this failure is currently unrecoverable. The work contained in this pull request introduces a failover mode and enables the daemon to recover in-flight requested-related objects. A restarted daemon will be able to process requests as usual. This requires that in-flight requests are stored during daemon crash or while the daemon is offline. In addition, a handle to /dev/cachefiles needs to be stored. This can be done by e.g., systemd's fdstore (cf. [1]) which enables the restarted daemon to recover state. Three new states are introduced in this patchset: (1) CLOSE Object is closed by the daemon. (2) OPEN Object is open and ready for processing. IOW, the open request has been handled successfully. (3) REOPENING Object has been previously closed and is now reopened due to a read request. A restarted daemon can recover the /dev/cachefiles fd from systemd's fdstore and writes "restore" to the device. This causes the object state to be reset from CLOSE to REOPENING and reinitializes the object. The daemon may now handle the open request. Any in-flight operations are restored and handled avoiding interruptions for users" Link: https://systemd.io/FILE_DESCRIPTOR_STORE [1] * tag 'vfs-6.8.cachefiles' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs: cachefiles: add restore command to recover inflight ondemand read requests cachefiles: narrow the scope of triggering EPOLLIN events in ondemand mode cachefiles: resend an open request if the read request's object is closed cachefiles: extract ondemand info field from cachefiles_object cachefiles: introduce object ondemand state

Pull vfs rw updates from Christian Brauner: "This contains updates from Amir for read-write backing file helpers for stacking filesystems such as overlayfs: - Fanotify is currently in the process of introducing pre content events. Roughly, a new permission event will be added indicating that it is safe to write to the file being accessed. These events are used by hierarchical storage managers to e.g., fill the content of files on first access. During that work we noticed that our current permission checking is inconsistent in rw_verify_area() and remap_verify_area(). Especially in the splice code permission checking is done multiple times. For example, one time for the whole range and then again for partial ranges inside the iterator. In addition, we mostly do permission checking before we call file_start_write() except for a few places where we call it after. For pre-content events we need such permission checking to be done before file_start_write(). So this is a nice reason to clean this all up. After this series, all permission checking is done before file_start_write(). As part of this cleanup we also massaged the splice code a bit. We got rid of a few helpers because we are alredy drowning in special read-write helpers. We also cleaned up the return types for splice helpers. - Introduce generic read-write helpers for backing files. This lifts some overlayfs code to common code so it can be used by the FUSE passthrough work coming in over the next cycles.
