Make AF_ALG sendmsg() support MSG_SPLICE_PAGES in the hashing code. This causes pages to be spliced from the source iterator if possible. This allows ->sendpage() to be replaced by something that can handle multiple multipage folios in a single transaction. Signed-off-by:

Convert af_alg_sendpage() to use sendmsg() with MSG_SPLICE_PAGES rather than directly splicing in the pages itself. This allows ->sendpage() to be replaced by something that can handle multiple multipage folios in a single transaction. Signed-off-by:

Convert AF_ALG to use iov_iter_extract_pages() instead of iov_iter_get_pages(). This will pin pages or leave them unaltered rather than getting a ref on them as appropriate to the iterator. The pages need to be pinned for DIO-read rather than having refs taken on them to prevent VM copy-on-write from malfunctioning during a concurrent fork() (the result of the I/O would otherwise end up only visible to the child process and not the parent).

Maxime Chevallier says: ==================== Followup fixes for the dwmac and altera lynx conversion Here's yet another version of the cleanup series for the TSE PCS replacement by PCS Lynx. It includes Kconfig fixups, some missing initialisations and a slight rework suggested by Russell for the dwmac cleanup sequence, along with more explicit zeroing of local structures as per MAciej's review. ==================== Link: https://lore.kernel.org/r/20230607135941.407054-1-maxime.chevallier@bootlin.comSigned-off-by:

When parsing multi-attr we count the objects and then allocate an array to hold the parsed objects. If an attr space has multiple multi-attr objects, however, if parsing the first array fails we'll leave the object count for the second even tho the second array was never allocated. This may cause crashes when freeing objects on error. Count attributes to a variable on the stack and only set the count in the object once the memory was allocated. Signed-off-by: -

txgbe_shutdown() relies on txgbe_dev_shutdown() to initialise wake by passing it by reference. However, txgbe_dev_shutdown() doesn't use this parameter at all. wake is then passed uninitialised by txgbe_dev_shutdown() to pci_wake_from_d3(). Resolve this problem by: * Removing the unused parameter from txgbe_dev_shutdown() * Removing the uninitialised variable wake from txgbe_dev_shutdown() * Passing false to pci_wake_from_d3() - this assumes that although uninitialised wake was in practice false (0). I'm not sure that this counts as a bug, as I'm not sure that it manifests in any unwanted behaviour. But in any case, the issue was introduced by: 3ce7547e ("net: txgbe: Add build support for txgbe") Flagged by Smatch as: .../txgbe_main.c:486 txgbe_shutdown() error: uninitialized symbol 'wake'. No functional change intended. Compile tested only. Signed-off-by:
