2024-04-16platform/x86/amd: pmf: Add quirk for ROG Zephyrus G14Mario Limonciello
ROG Zephyrus G14 advertises support for SPS notifications to the BIOS but doesn't actually use them. Instead the asus-nb-wmi driver utilizes such events. Add a quirk to prevent the system from registering for ACPI platform profile when this system is found to avoid conflicts.

Currently, "active reset" cases are flaky, because select() is called for 3 sockets, while only 2 are expected to receive RST.

2024-04-15inet: bring NLM_DONE out to a separate recv() againJakub Kicinski
Commit under Fixes optimized the number of recv() calls needed during RTM_GETROUTE dumps, but we got multiple reports of applications hanging on recv() calls. Applications expect that a route dump will be terminated with a recv() reading an individual NLM_DONE message. Coalescing NLM_DONE is perfectly legal in netlink, but even tho reporters fixed the code in respective projects, chances are it will take time for those applications to get updated. So revert to old behavior (for now)?

2024-04-14net: change maximum number of UDP segments to 128Yuri Benditovich
The commit fc8b2a619469 ("net: more strict VIRTIO_NET_HDR_GSO_UDP_L4 validation") adds check of potential number of UDP segments vs UDP_MAX_SEGMENTS in linux/virtio_net.h. After this change certification test of USO guest-to-guest transmit on Windows driver for virtio-net device fails, for example with packet size of ~64K and mss of 536 bytes. In general the USO should not be more restrictive than TSO. Indeed, in case of unreasonably small mss a lot of segments can cause queue overflow and packet loss on the destination. Limit of 128 segments is good for any practical purpose, with minimal meaningful mss of 536 the maximal UDP packet will be divided to ~120 segments. The number of segments for UDP packets is validated vs UDP_MAX_SEGMENTS also in udp.c (v4,v6), this does not affect quest-to-guest path but does affect packets sent to host, for example. It is important to mention that UDP_MAX_SEGMENTS is kernel-only define and not available to user mode socket applications. In order to request MSS smaller than MTU the applications just uses setsockopt with SOL_UDP and UDP_SEGMENT and there is no limitations on socket API level.

2024-04-13bcachefs: Fix btree node merging on write buffer btreesKent Overstreet
The btree write buffer flush fastpath that avoids the main transaction commit path had the unfortunate side effect of not doing btree node merging. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2024-04-13bcachefs: Disable merges from interior update pathKent Overstreet
There's been a bug in the btree write buffer where it wasn't triggering btree node merges - and leaving behind a bunch of nearly empty btree nodes. Then during journal replay, when updates to the backpointers btree aren't using the btree write buffer (because we require synchronization with journal replay), we end up doing those merges all at once. Then if it's the interior update path running them, we deadlock because those run with the highest watermark. There's no real need for the interior update path to be doing btree node merges; other code paths can handle that at lower watermarks. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2024-04-13bcachefs: Run merges at BCH_WATERMARK_btreeKent Overstreet
This fixes a deadlock where the interior update path during journal replay ends up doing a ton of merges on the backpointers btree, and deadlocking. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>

2024-04-13bcachefs: Fix deadlock in journal replayKent Overstreet
btree_key_can_insert_cached() should be checking the watermark - BCH_TRANS_COMMIT_journal_replay really means nonblocking mode when watermark < reclaim, it was being used incorrectly. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>

2024-04-13bcachefs: Fix UAFs of btree_insert_entry arrayKent Overstreet
The btree paths array is now dynamically resizable - and as well the btree_insert_entries array, as it needs to be the same size. The merge path (and interior update path) allocates new btree paths, thus can trigger a resize; thus we need to not retain direct pointers after invoking merge; similarly when running btree node triggers.

git://git.kernel.org/pub/scm/linux/kernel/git/libata/linux Pull ata fixes from Damien Le Moal: - Add the mask_port_map parameter to the ahci driver. This is a follow-up to the recent snafu with the ASMedia controller and its virtual port hidding port-multiplier devices. As ASMedia confirmed that there is no way to determine if these slow-to-probe virtual ports are actually representing the ports of a port-multiplier devices, this new parameter allow masking ports to significantly speed up probing during system boot, resulting in shorter boot times. - A fix for an incorrect handling of a port unlock in ata_scsi_dev_rescan(). - Allow command duration limits to be detected for ACS-4 devices are there are such devices out in the field. * tag 'ata-6.9-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/libata/linux: ata: libata-core: Allow command duration limits detection for ACS-4 drives ata: libata-scsi: Fix ata_scsi_dev_rescan() error path ata: ahci: Add mask_port_map module parameter
