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).

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. Fixes: 442a35a5 ("bnxt: convert to new udp_tunnel_nic infra") Reviewed-by:

The firmware can send PHC_RTC_UPDATE async event on a PF that may not have PTP registered. In such a case, there will be a null pointer deference for bp->ptp_cfg when we try to handle the event. Fix it by not registering for this event with the firmware if !bp->ptp_cfg. Also, check that bp->ptp_cfg is valid before proceeding when we receive the event.

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.

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. Fixes: 7a13240e ("bnxt_en: fix ethtool_reset_flags ABI violations") Reviewed-by:
