2023-06-08tcp: let tcp_mtu_probe() build headless packetsEric Dumazet
tcp_mtu_probe() is still copying payload from skbs in the write queue, using skb_copy_bits(), ignoring potential errors. Modern TCP stack wants to only deal with payload found in page frags, as this is a prereq for TCPDirect (host stack might not have access to the payload) Signed-off-by: Eric Dumazet <edumazet@google.com> Link: https://lore.kernel.org/r/20230607214113.1992947-1-edumazet@google.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>

This series adds support for 4 ports VF LAG (single FDB E-Switch). This series of patches refactoring LAG code that make assumptions about VF LAG supporting only two ports and then enable 4 ports VF LAG. Patch 1: - Fix for ib rep code Patches 2-5: - Refactors LAG layer. Patches 6-7: - Block LAG types which doesn't support 4 ports. Patch 8: - Enable 4 ports VF LAG. This series specifically allows HCAs with 4 ports to create a VF LAG with only 4 ports. It is not possible to create a VF LAG with 2 or 3 ports using HCAs that have 4 ports. Currently, the Merged E-Switch feature only supports HCAs with 2 ports. However, upcoming patches will introduce support for HCAs with 4 ports. In order to activate VF LAG a user can execute: devlink dev eswitch set pci/0000:08:00.0 mode switchdev devlink dev eswitch set pci/0000:08:00.1 mode switchdev devlink dev eswitch set pci/0000:08:00.2 mode switchdev devlink dev eswitch set pci/0000:08:00.3 mode switchdev ip link add name bond0 type bond ip link set dev bond0 type bond mode 802.3ad ip link set dev eth2 master bond0 ip link set dev eth3 master bond0 ip link set dev eth4 master bond0 ip link set dev eth5 master bond0 Where eth2, eth3, eth4 and eth5 are net-interfaces of pci/0000:08:00.0 pci/0000:08:00.1 pci/0000:08:00.2 pci/0000:08:00.3 respectively.

2023-06-08Merge branch 'complete-lynx-mdio-device-handling'Jakub Kicinski
Russell King says: ==================== complete Lynx mdio device handling This series completes the mdio device lifetime handling for Lynx PCS users which do not create their own mdio device, but instead fetch it using a firmware description - namely the DPAA2 and FMAN_MEMAC drivers. In a previous patch set, lynx_pcs_create() was modified to increase the mdio device refcount, and lynx_pcs_destroy() to drop that refcount. The first two patches change these two drivers to put the reference which they hold immediately after lynx_pcs_create(), effectively handing the responsibility for maintaining the refcount to the Lynx PCS driver. A side effect of the first two patches is that lynx_get_mdio_device() is no longer used, so patch 3 removes it. Patch 4 adds a new helper - lynx_pcs_create_fwnode(), which creates a Lynx PCS instance from the fwnode. Patch 5 and 6 convert the two drivers to make use of this new helper, which simply has to find the mdio device, and then create the Lynx PCS from that. With those conversions done, lynx_pcs_create() is no longer required outside pcs-lynx.c, so remove it from public view. Patch 8 we changes lynx_pcs_create() to return an error-pointer rather than NULL to bring consistency to the return style, and means that we can remove the NULL-to-error-pointer conversion from both lynx_pcs_create_fwnode() and lynx_pcs_create_mdiodev(). Patch 9 adds a check for the fwnode being available, and returns an -ENODEV error pointer if unavailable. Patch 10 removes this check from DPAA2, detecting the error pointer value to continue printing the helpful message. Patch 11 removes this check from fman_memac, and in doing so fixes a bug where if the node is unavailable, the reference count is not dropped. ==================== Link: https://lore.kernel.org/r/ZIBwuw+IuGQo5yV8@shell.armlinux.org.uk Signed-off-by: Jakub Kicinski <kuba@kernel.org>

David Howells says: ==================== crypto, splice, net: Make AF_ALG handle sendmsg(MSG_SPLICE_PAGES) Here are patches to make AF_ALG handle the MSG_SPLICE_PAGES internal sendmsg flag. MSG_SPLICE_PAGES is an internal hint that tells the protocol that it should splice the pages supplied if it can. The sendpage functions are then turned into wrappers around that. This set consists of the following parts: (1) Move netfs_extract_iter_to_sg() to somewhere more general and rename it to drop the "netfs" prefix. We use this to extract directly from an iterator into a scatterlist. (2) Make AF_ALG use iov_iter_extract_pages(). This has the additional effect of pinning pages obtained from userspace rather than taking refs on them. Pages from kernel-backed iterators would not be pinned, but AF_ALG isn't really meant for use by kernel services. (3) Change AF_ALG still further to use extract_iter_to_sg(). (4) Make af_alg_sendmsg() support MSG_SPLICE_PAGES support and make af_alg_sendpage() just a wrapper around sendmsg(). This has to take refs on the pages pinned for the moment. (5) Make hash_sendmsg() support MSG_SPLICE_PAGES by simply ignoring it. hash_sendpage() is left untouched to be removed later, after the splice core has been changed to call sendmsg(). ==================== Link: https://lore.kernel.org/r/20230606130856.1970660-1-dhowells@redhat.com Signed-off-by: Paolo Abeni <pabeni@redhat.com>

2023-06-08crypto: af_alg: Pin pages rather than ref'ing if appropriateDavid Howells
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).
