We should use a device-tree name that is upstreamable. * use eswin/eic7700-hifive-premier-p550.dtb as device-tree name * use "SiFive HiFive Premier P550" as model property * use "sifive,hifive-premier-p550", "eswin,eic7700" as compatible strings Signed-off-by: Heinrich Schuchardt <heinrich.schuchardt@canonical.com>

commit 40e9cd4ae8ec43b107ed2bff422a8fa39dcf4e4b upstream. Quiesce and resume is a mechanism to suspend operations on DASD devices. In the context of a controlled copy pair swap operation, the quiesce operation is usually issued before the actual swap and a resume afterwards. During the swap operation, the underlying device is exchanged. Therefore, the quiesce flag must be moved to the secondary device to ensure a consistent quiesce state after the swap. The secondary device itself cannot be suspended separately because there is no separate block device representation for it.

commit 4c527c7e030672efd788d0806d7a68972a7ba3c1 upstream. During online processing for a DASD device an IO operation is started to determine the format of the device. CDL format contains specifically sized blocks at the beginning of the disk. For a PPRC secondary device no real IO operation is possible therefore this IO request can not be started and this step is skipped for online processing of secondary devices. This is generally fine since the secondary is a copy of the primary device. In case of an additional partition detection that is run after a swap operation the format information is needed to properly drive partition detection IO. Currently the information is not passed leading to IO errors during partition detection and a wrongly detected partition table which in turn might lead to data corruption on the disk with the wrong partition table. Fix by passing the format information from primary to secondary device.

commit d78840a6a38d312dc1a51a65317bb67e46f0b929 upstream. SMB2_write() places write payload in iov[1..n] as part of rq_iov. smb3_init_transform_rq() pointer-shares rq_iov, so crypt_message() encrypts iov[1] in-place, replacing the original plaintext with ciphertext. On a replayable error, the retry sends the same iov[1] which now contains ciphertext instead of the original data, resulting in corruption. The corruption is most likely to be observed when connections are unstable, as reconnects trigger write retries that re-send the already-encrypted data. This affects SFU mknod, MF symlinks, etc. On kernels before 6.10 (prior to the netfs conversion), sync writes also used this path and were similarly affected. The async write path wasn't unaffected as it uses rq_iter which gets deep-copied. Fix by moving the write payload into rq_iter via iov_iter_kvec(), so smb3_init_transform_rq() deep-copies it before encryption.

…nd napi_tx is false commit ba8bda9a0896746053aa97ac6c3e08168729172c upstream. A UAF issue occurs when the virtio_net driver is configured with napi_tx=N and the device's IFF_XMIT_DST_RELEASE flag is cleared (e.g., during the configuration of tc route filter rules). When IFF_XMIT_DST_RELEASE is removed from the net_device, the network stack expects the driver to hold the reference to skb->dst until the packet is fully transmitted and freed. In virtio_net with napi_tx=N, skbs may remain in the virtio transmit ring for an extended period. If the network namespace is destroyed while these skbs are still pending, the corresponding dst_ops structure has freed. When a subsequent packet is transmitted, free_old_xmit() is triggered to clean up old skbs. It then calls dst_release() on the skb associated with the stale dst_entry. Since the dst_ops (referenced by the dst_entry) has already been freed, a UAF kernel paging request occurs. fix it by adds skb_dst_drop(skb) in start_xmit to explicitly release the dst reference before the skb is queued in virtio_net.

[ Upstream commit 317e49358ebbf6390fa439ef3c142f9239dd25fb ]
The devm_free_irq() and devm_request_irq() functions should not be
executed in an atomic context.
During device suspend, all userspace processes and most kernel threads
are frozen. Additionally, we flush all tx/rx status, disable all macb
interrupts, and halt rx operations. Therefore, it is safe to split the
region protected by bp->lock into two independent sections, allowing
devm_free_irq() and devm_request_irq() to run in a non-atomic context.
This modification resolves the following lockdep warning:
