2023-06-08tools: ynl: add sample for devlinkJakub Kicinski
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 ...

2023-06-08tools: ynl: generate code for the devlink familyJakub Kicinski
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: Jakub Kicinski <kuba@kernel.org>
2023-06-08tools: ynl-gen: don't generate forward declarations for policies - regenJakub Kicinski
Renegerate code after dropping forward declarations for policies. Signed-off-by: Jakub Kicinski <kuba@kernel.org>
2023-06-08tools: ynl-gen: don't generate forward declarations for policiesJakub Kicinski
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: Jakub Kicinski <kuba@kernel.org>
2023-06-08tools: ynl-gen: walk nested types in depthJakub Kicinski
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: Jakub Kicinski <kuba@kernel.org>
2023-06-08tools: ynl-gen: inherit struct use infoJakub Kicinski
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: Jakub Kicinski <kuba@kernel.org>
2023-06-08tools: ynl-gen: try to sort the types more intelligentlyJakub Kicinski
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: Jakub Kicinski <kuba@kernel.org>

2023-06-08tools: ynl-gen: use enum names in op strmap more carefullyJakub Kicinski
In preparation for supporting families which use different msg ids to and from the kernel - make sure the ids in op strmap are correct. The map is expected to be used mostly for notifications, don't generate a separate map for the "to kernel" direction. Signed-off-by: Jakub Kicinski <kuba@kernel.org>
2023-06-08netlink: specs: devlink: fill in some details important for CJakub Kicinski

2023-06-08Merge branch 'crypto-splice-net-make-af_alg-handle-sendmsg-msg_splice_pages'Paolo Abeni
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).

2023-06-08bnxt_en: Implement .set_port / .unset_port UDP tunnel callbacksSomnath Kotur
As per the new udp tunnel framework, drivers which need to know the details of a port entry (i.e. port type) when it gets deleted should use the .set_port / .unset_port callbacks. Implementing the current .udp_tunnel_sync callback would mean that the deleted tunnel port entry would be all zeros. This used to work on older firmware because it would not check the input when deleting a tunnel port. With newer firmware, the delete will now fail and subsequent tunnel port allocation will fail as a result.

2023-06-08bnxt_en: Skip firmware fatal error recovery if chip is not accessibleVikas Gupta
Driver starts firmware fatal error recovery by detecting heartbeat failure or fw reset count register changing. But these checks are not reliable if the device is not accessible. This can happen while DPC (Downstream Port containment) is in progress. Skip firmware fatal recovery if pci_device_is_present() returns false.

2023-06-08bnxt_en: Query default VLAN before VNIC setup on a VFSomnath Kotur
We need to call bnxt_hwrm_func_qcfg() on a VF to query the default VLAN that may be setup by the PF. If a default VLAN is enabled, the VF cannot support VLAN acceleration on the receive side and the VNIC must be setup to strip out the default VLAN tag. If a default VLAN is not enabled, the VF can support VLAN acceleration on the receive side. The VNIC should be set up to strip or not strip the VLAN based on the RX VLAN acceleration setting. Without this call to determine the default VLAN before calling bnxt_setup_vnic(), the VNIC may not be set up correctly. For example, bnxt_setup_vnic() may set up to strip the VLAN tag based on stale default VLAN information. If RX VLAN acceleration is not enabled, the VLAN tag will be incorrectly stripped and the RX data path will not work correctly.

2023-06-08bnxt_en: Don't issue AP reset during ethtool's reset operationSreekanth Reddy
Only older NIC controller's firmware uses the PROC AP reset type. Firmware on 5731X/5741X and newer chips does not support this reset type. When bnxt_reset() issues a series of resets, this PROC AP reset may actually fail on these newer chips because the firmware is not ready to accept this unsupported command yet. Avoid this unnecessary error by skipping this reset type on chips that don't support it.

The down condition should be the negation of the wake condition, IOW when I moved it from: if (cond && wake()) to if (__netif_txq_completed_wake(cond)) Cond should have been negated. Flip it now. This bug leads to occasional crashes with netconsole. It may also lead to queue never waking up in case BQL is not enabled.
