Pablo Neira Ayuso says: ==================== Netfilter fixes for net The following patchset contains Netfilter fixes for net: 1) Narrow down target/match revision to u8 in nft_compat. 2) Bail out with unused flags in nft_compat. 3) Restrict layer 4 protocol to u16 in nft_compat. 4) Remove static in pipapo get command that slipped through when reducing set memory footprint. 5) Follow up incremental fix for the ipset performance regression, this includes the missing gc cancellation, from Jozsef Kadlecsik. 6) Allow to filter by zone 0 in ctnetlink, do not interpret zone 0 as no filtering, from Felix Huettner. 7) Reject direction for NFT_CT_ID. 8) Use timestamp to check for set element expiration while transaction is handled to prevent garbage collection from removing set elements that were just added by this transaction. Packet path and netlink dump/get path still use current time to check for expiration. 9) Restore NF_REPEAT in nfnetlink_queue, from Florian Westphal. 10) map_index needs to be percpu and per-set, not just percpu. At this time its possible for a pipapo set to fill the all-zero part with ones and take the 'might have bits set' as 'start-from-zero' area. From Florian Westphal. This includes three patches: - Change scratchpad area to a structure that provides space for a per-set-and-cpu toggle and uses it of the percpu one. - Add a new free helper to prepare for the next patch. - Remove the scratch_aligned pointer and makes AVX2 implementation use the exact same memory addresses for read/store of the matching state. netfilter pull request 24-02-08 * tag 'nf-24-02-08' of git://git.kernel.org/pub/scm/linux/kernel/git/netfilter/nf: netfilter: nft_set_pipapo: remove scratch_aligned pointer netfilter: nft_set_pipapo: add helper to release pcpu scratch area netfilter: nft_set_pipapo: store index in scratch maps netfilter: nft_set_rbtree: skip end interval element from gc netfilter: nfnetlink_queue: un-break NF_REPEAT netfilter: nf_tables: use timestamp to check for set element timeout netfilter: nft_ct: reject direction for ct id netfilter: ctnetlink: fix filtering for zone 0 netfilter: ipset: Missing gc cancellations fixed netfilter: nft_set_pipapo: remove static in nft_pipapo_get() netfilter: nft_compat: restrict match/target protocol to u16 netfilter: nft_compat: reject unused compat flag netfilter: nft_compat: narrow down revision to unsigned 8-bits ==================== Link: https://lore.kernel.org/r/20240208112834.1433-1-pablo@netfilter.orgSigned-off-by: Paolo Abeni <pabeni@redhat.com>

use ->scratch for both avx2 and the generic implementation. After previous change the scratch->map member is always aligned properly for AVX2, so we can just use scratch->map in AVX2 too. The alignoff delta is stored in the scratchpad so we can reconstruct the correct address to free the area again.

Pipapo needs a scratchpad area to keep state during matching. This state can be large and thus cannot reside on stack. Each set preallocates percpu areas for this. On each match stage, one scratchpad half starts with all-zero and the other is inited to all-ones. At the end of each stage, the half that starts with all-ones is always zero. Before next field is tested, pointers to the two halves are swapped, i.e. resmap pointer turns into fill pointer and vice versa. After the last field has been processed, pipapo stashes the index toggle in a percpu variable, with assumption that next packet will start with the all-zero half and sets all bits in the other to 1. This isn't reliable. There can be multiple sets and we can't be sure that the upper and lower half of all set scratch map is always in sync (lookups can be conditional), so one set might have swapped, but other might not have been queried. Thus we need to keep the index per-set-and-cpu, just like the scratchpad. Note that this bug fix is incomplete, there is a related issue. avx2 and normal implementation might use slightly different areas of the map array space due to the avx2 alignment requirements, so m->scratch (generic/fallback implementation) and ->scratch_aligned (avx) may partially overlap. scratch and scratch_aligned are not distinct objects, the latter is just the aligned address of the former. After this change, write to scratch_align->map_index may write to scratch->map, so this issue becomes more prominent, we can set to 1 a bit in the supposedly-all-zero area of scratch->map[]. A followup patch will remove the scratch_aligned and makes generic and avx code use the same (aligned) area. Its done in a separate change to ease review.

Add a timestamp field at the beginning of the transaction, store it in the nftables per-netns area. Update set backend .insert, .deactivate and sync gc path to use the timestamp, this avoids that an element expires while control plane transaction is still unfinished. .lookup and .update, which are used from packet path, still use the current time to check if the element has expired. And .get path and dump also since this runs lockless under rcu read size lock. Then, there is async gc which also needs to check the current time since it runs asynchronously from a workqueue.

Symptom: In case of a bad cable connection (e.g. dirty optics) a fast sequence of network DOWN-UP-DOWN-UP could happen. UP triggers recovery of the qeth interface. In case of a second DOWN while recovery is still ongoing, it can happen that the IP@ of a Layer3 qeth interface is lost and will not be recovered by the second UP. Problem: When registration of IP addresses with Layer 3 qeth devices fails, (e.g. because of bad address format) the respective IP address is deleted from its hash-table in the driver. If registration fails because of a ENETDOWN condition, the address should stay in the hashtable, so a subsequent recovery can restore it. 3caa4af8 ("qeth: keep ip-address after LAN_OFFLINE failure") fixes this for registration failures during normal operation, but not during recovery. Solution: Keep L3-IP address in case of ENETDOWN in qeth_l3_recover_ip(). For consistency with qeth_l3_add_ip() we also keep it in case of EADDRINUSE, i.e. for some reason the card already/still has this address registered.

The patch fdb8e12cc2cc ("netfilter: ipset: fix performance regression in swap operation") missed to add the calls to gc cancellations at the error path of create operations and at module unload. Also, because the half of the destroy operations now executed by a function registered by call_rcu(), neither NFNL_SUBSYS_IPSET mutex or rcu read lock is held and therefore the checking of them results false warnings.

Set mac_managed_pm be true to tell mdio that the phy resume/suspend is managed by the mac, to fix the following warning: WARNING: CPU: 0 PID: 965 at drivers/net/phy/phy_device.c:326 mdio_bus_phy_resume+0x140/0x144 CPU: 0 PID: 965 Comm: sh Tainted: G O 6.1.46-g247b2535b2 #1 Hardware name: Generic AM33XX (Flattened Device Tree) unwind_backtrace from show_stack+0x18/0x1c show_stack from dump_stack_lvl+0x24/0x2c dump_stack_lvl from __warn+0x84/0x15c __warn from warn_slowpath_fmt+0x1a8/0x1c8 warn_slowpath_fmt from mdio_bus_phy_resume+0x140/0x144 mdio_bus_phy_resume from dpm_run_callback+0x3c/0x140 dpm_run_callback from device_resume+0xb8/0x2b8 device_resume from dpm_resume+0x144/0x314 dpm_resume from dpm_resume_end+0x14/0x20 dpm_resume_end from suspend_devices_and_enter+0xd0/0x924 suspend_devices_and_enter from pm_suspend+0x2e0/0x33c pm_suspend from state_store+0x74/0xd0 state_store from kernfs_fop_write_iter+0x104/0x1ec kernfs_fop_write_iter from vfs_write+0x1b8/0x358 vfs_write from ksys_write+0x78/0xf8 ksys_write from ret_fast_syscall+0x0/0x54 Exception stack(0xe094dfa8 to 0xe094dff0) dfa0: 00000004 005c3fb8 00000001 005c3fb8 00000004 00000001 dfc0: 00000004 005c3fb8 b6f6bba0 00000004 00000004 0059edb8 00000000 00000000 dfe0: 00000004 bed918f0 b6f09bd3 b6e89a66 Cc: <stable@vger.kernel.org> # v6.0+ Fixes: 744d23c7 ("net: phy: Warn about incorrect mdio_bus_phy_resume() state") Fixes: fba863b8 ("net: phy: make PHY PM ops a no-op if MAC driver manages PHY PM") Signed-off-by: Sinthu Raja <sinthu.raja@ti.com> Signed-off-by: Paolo Abeni <pabeni@redhat.com>

Since commit 48e1b4d3 ("gpiolib: remove the GPIO device from the list when it's unregistered") we remove the GPIO device entry from the global list (used to order devices by their GPIO ranges) when unregistering the chip, not when releasing the device. It will not happen when the last reference is put anymore. This means, we need to remove it in error path in gpiochip_add_data_with_key() unconditionally, without checking if the device's .release() callback is set.

If GUP fails and we are in_kthread, we can have pinned = 0 and ret = 0. If that happens we call sg_alloc_append_table_from_pages() with n_pages = 0, which is not well behaved and can trigger: kernel BUG at include/linux/scatterlist.h:115! depending on if the pages array happens to be zeroed or not. Even if we don't hit that it crashes later when trying to dma_map the returned table.

The calculation to determine max page size of a VMA during a REMAP operations assumes the VMA has been bound. This assumption is not true if the VMA is from an eariler operation in an array of binds. If a VMA has not been bound use the maximum page size which will ensure the previous / next REMAP operations are not incorrectly skipped.
