Change lynx_pcs_create() to return an error-pointer on failure to allocate memory, rather than returning NULL. This allows the removal of the conversion in lynx_pcs_create_fwnode() and lynx_pcs_create_mdiodev(). Signed-off-by:

MIPS Boston board, which is using MIPS_GENERIC kernel is using EG20T PCH and thus need this driver. Dependency of PCH_GBE, PTP_1588_CLOCK_PCH is also fixed for MIPS_GENERIC. Note that CONFIG_PCH_GBE is selected in arch/mips/configs/generic/ board-boston.config for a while, some how it's never wired up in Kconfig. Signed-off-by:

The recently added 'VXLAN_F_LOCALBYPASS' flag is set by default on VXLAN devices and denotes a behavior that is irrelevant for the hardware data path. Add it to the lists of IPv4 and IPv6 supported flags to avoid rejecting offload of VXLAN devices which have this flag set. Fixes: 69474a8a ("net: vxlan: Add nolocalbypass option to vxlan.")

Jakub Kicinski says: ==================== tools: ynl: generate code for the devlink family Another chunk of changes to support more capabilities in the YNL code gen. Devlink brings in deep nesting and directional messages (requests and responses have different IDs). We need a healthy dose of codegen changes to support those (I wasn't planning to support code gen for "directional" families initially, but the importance of devlink and ethtool is undeniable). ==================== Link: https://lore.kernel.org/r/20230607202403.1089925-1-kuba@kernel.orgSigned-off-by:

Add a sample to show off how to issue basic devlink requests. For added testing issue get requests while walking a dump. $ ./devlink netdevsim/netdevsim1: driver: netdevsim running fw: fw.mgmt: 10.20.30 ... netdevsim/netdevsim2: driver: netdevsim running fw: fw.mgmt: 10.20.30 ... Signed-off-by: -

Admittedly the devlink.yaml spec is fairly limitted, it only covers basic device get and info-get ops. That's sufficient to be useful (monitoring FW versions in the fleet). Plus it gives us a chance to exercise deep nesting and directional messaging in YNL. Signed-off-by: -

Now that all nested types have structs and are sorted topologically there should be no need to generate forward declarations for policies. Signed-off-by: -

So far we had only created structures for nested types nested directly in messages (second level of attrs so to speak). Walk types in depth to support deeper nesting. Signed-off-by: -

We only render parse and netlink generation helpers as needed, to avoid generating dead code. Propagate the information from first- and second-layer attribute sets onto all children. Otherwise devlink won't work, it has a lot more levels of nesting. Signed-off-by: -

We need to sort the structures to avoid the need for forward declarations. While at it remove the sort of structs when rendering, it doesn't do anything. Signed-off-by: -

Pull xfs fixes from Dave Chinner: "These are a set of regression fixes discovered on recent kernels. I was hoping to send this to you a week and half ago, but events out of my control delayed finalising the changes until early this week. Whilst the diffstat looks large for this stage of the merge window, a large chunk of it comes from moving the guts of one function from one file to another i.e. it's the same code, it is just run in a different context where it is safe to hold a specific lock. Otherwise the individual changes are relatively small and straigtht forward. Summary: - Propagate unlinked inode list corruption back up to log recovery (regression fix) - improve corruption detection for AGFL entries, AGFL indexes and XEFI extents (syzkaller fuzzer oops report) - Avoid double perag reference release (regression fix) - Improve extent merging detection in scrub (regression fix) - Fix a new undefined high bit shift (regression fix) - Fix for AGF vs inode cluster buffer deadlock (regression fix)" * tag 'xfs-6.4-rc5-fixes' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux: xfs: collect errors from inodegc for unlinked inode recovery xfs: validate block number being freed before adding to xefi xfs: validity check agbnos on the AGFL xfs: fix agf/agfl verification on v4 filesystems xfs: fix double xfs_perag_rele() in xfs_filestream_pick_ag() xfs: fix broken logic when detecting mergeable bmap records xfs: Fix undefined behavior of shift into sign bit xfs: fix AGF vs inode cluster buffer deadlock xfs: defered work could create precommits xfs: restore allocation trylock iteration xfs: buffer pins need to hold a buffer reference -

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.comSigned-off-by:Paolo Abeni <pabeni@redhat.com>

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).
