Commit 65b32f80 ("uapi: move IPPROTO_L2TP to in.h") moved the definition of IPPROTO_L2TP from a define to an enum, but since __stringify doesn't work properly with enums, we ended up breaking the modalias strings for the l2tp modules: $ modinfo l2tp_ip l2tp_ip6 | grep alias alias: net-pf-2-proto-IPPROTO_L2TP alias: net-pf-2-proto-2-type-IPPROTO_L2TP alias: net-pf-10-proto-IPPROTO_L2TP alias: net-pf-10-proto-2-type-IPPROTO_L2TP Use the resolved number directly in MODULE_ALIAS_*() macros (as we already do with SOCK_DGRAM) to fix the alias strings: $ modinfo l2tp_ip l2tp_ip6 | grep alias alias: net-pf-2-proto-115 alias: net-pf-2-proto-115-type-2 alias: net-pf-10-proto-115 alias: net-pf-10-proto-115-type-2 Moreover, fix the ordering of the parameters passed to MODULE_ALIAS_NET_PF_PROTO_TYPE() by switching proto and type.

Currently, intel_speed_mode_2500() will fix-up xpcs_an_inband to 1 if the underlying controller has a max speed of 1000Mbps. The value has been initialized and modified if it is a fixed-linked setup earlier. This patch removes the fix-up to allow for fixed-linked setup support. In stmmac_phy_setup(), ovr_an_inband is set based on the value of xpcs_an_inband. Which in turn will return an error in phylink_parse_mode() where MLO_AN_FIXED and ovr_an_inband are both set.

This patch sets the skb owner in the recv and send path for virtio. For the send path, this solves the leak caused when virtio_transport_purge_skbs() finds skb->sk is always NULL and therefore never matches it with the current socket. Setting the owner upon allocation fixes this. For the recv path, this ensures correctness of accounting and also correct transfer of ownership in vsock_loopback (when skbs are sent from one socket and received by another).

Commit 7dd76d1f ("dm: improve bio splitting and associated IO accounting") only called setup_split_accounting() from __send_duplicate_bios() if a single bio were being issued. But the case where duplicate bios are issued must call it too. Otherwise the bio won't be split and resubmitted (via recursion through block core back to DM) to submit the later portions of a bio (which may map to an entirely different target). For example, when discarding an entire DM striped device with the following DM table: vg-lvol0: 0 159744 striped 2 128 7:0 2048 7:1 2048 vg-lvol0: 159744 45056 striped 2 128 7:2 2048 7:3 2048 Before (broken, discards the first striped target's devices twice): device-mapper: striped: target_stripe=0, bdev=7:0, start=2048 len=79872 device-mapper: striped: target_stripe=1, bdev=7:1, start=2048 len=79872 device-mapper: striped: target_stripe=0, bdev=7:0, start=2049 len=22528 device-mapper: striped: target_stripe=1, bdev=7:1, start=2048 len=22528 After (works as expected): device-mapper: striped: target_stripe=0, bdev=7:0, start=2048 len=79872 device-mapper: striped: target_stripe=1, bdev=7:1, start=2048 len=79872 device-mapper: striped: target_stripe=0, bdev=7:2, start=2048 len=22528 device-mapper: striped: target_stripe=1, bdev=7:3, start=2048 len=22528 Fixes: 7dd76d1f ("dm: improve bio splitting and associated IO accounting") Cc: stable@vger.kernel.org Reported-by:

"Abnormal" bios include discards, write zeroes and secure erase. By no longer passing the calculated 'len' pointer, commit 7dd06a25 ("dm: allow dm_accept_partial_bio() for dm_io without duplicate bios") took a senseless approach to disallowing dm_accept_partial_bio() from working for duplicate bios processed using __send_duplicate_bios(). It inadvertently and incorrectly stopped the use of 'len' when initializing a target's io (in alloc_tio). As such the resulting tio could address more area of a device than it should. For example, when discarding an entire DM striped device with the following DM table: vg-lvol0: 0 159744 striped 2 128 7:0 2048 7:1 2048 vg-lvol0: 159744 45056 striped 2 128 7:2 2048 7:3 2048 Before this fix: device-mapper: striped: target_stripe=0, bdev=7:0, start=2048 len=102400 blkdiscard: attempt to access beyond end of device loop0: rw=2051, sector=2048, nr_sectors = 102400 limit=81920 device-mapper: striped: target_stripe=1, bdev=7:1, start=2048 len=102400 blkdiscard: attempt to access beyond end of device loop1: rw=2051, sector=2048, nr_sectors = 102400 limit=81920 After this fix; device-mapper: striped: target_stripe=0, bdev=7:0, start=2048 len=79872 device-mapper: striped: target_stripe=1, bdev=7:1, start=2048 len=79872 Fixes: 7dd06a25 ("dm: allow dm_accept_partial_bio() for dm_io without duplicate bios") Cc: stable@vger.kernel.org Reported-by:

Reported on the Turris forum, mvneta provokes kernel warnings in the architecture DMA mapping code when mvneta_setup_txqs() fails to allocate memory. This happens because when mvneta_cleanup_txqs() is called in the mvneta_stop() path, we leave pointers in the structure that have been freed. Then on mvneta_open(), we call mvneta_setup_txqs(), which starts allocating memory. On memory allocation failure, mvneta_cleanup_txqs() will walk all the queues freeing any non-NULL pointers - which includes pointers that were previously freed in mvneta_stop(). Fix this by setting these pointers to NULL to prevent double-freeing of the same memory.

If certain conditions are met, DSA can install all necessary MAC addresses on the CPU ports as FDB entries and disable flooding towards the CPU (we call this RX filtering). There is one corner case where this does not work. ip link add br0 type bridge vlan_filtering 1 && ip link set br0 up ip link set swp0 master br0 && ip link set swp0 up ip link add link swp0 name swp0.100 type vlan id 100 ip link set swp0.100 up && ip addr add 192.168.100.1/24 dev swp0.100 Traffic through swp0.100 is broken, because the bridge turns on VLAN filtering in the swp0 port (causing RX packets to be classified to the FDB database corresponding to the VID from their 802.1Q header), and although the 8021q module does call dev_uc_add() towards the real device, that API is VLAN-unaware, so it only contains the MAC address, not the VID; and DSA's current implementation of ndo_set_rx_mode() is only for VID 0 (corresponding to FDB entries which are installed in an FDB database which is only hit when the port is VLAN-unaware). It's interesting to understand why the bridge does not turn on IFF_PROMISC for its swp0 bridge port, and it may appear at first glance that this is a regression caused by the logic in commit 2796d0c6 ("bridge: Automatically manage port promiscuous mode."). After all, a bridge port needs to have IFF_PROMISC by its very nature - it needs to receive and forward frames with a MAC DA different from the bridge ports' MAC addresses. While that may be true, when the bridge is VLAN-aware *and* it has a single port, there is no real reason to enable promiscuity even if that is an automatic port, with flooding and learning (there is nowhere for packets to go except to the BR_FDB_LOCAL entries), and this is how the corner case appears. Adding a second automatic interface to the bridge would make swp0 promisc as well, and would mask the corner case. Given the dev_uc_add() / ndo_set_rx_mode() API is what it is (it doesn't pass a VLAN ID), the only way to address that problem is to install host FDB entries for the cartesian product of RX filtering MAC addresses and VLAN RX filters.

The call to invalidate_inode_pages2_range() in __iomap_dio_rw() may fail, in which case -ENOTBLK is returned and this error code is propagated back to user space trhough iomap_dio_rw() -> zonefs_file_dio_write() return chain. This error code is fairly obscure and may confuse the user. Avoid this and be consistent with the behavior of zonefs_file_dio_append() for similar invalidate_inode_pages2_range() errors by returning -EBUSY to user space when iomap_dio_rw() returns -ENOTBLK.

When a direct append write is executed, the append offset may correspond to the last page of a sequential file inode which might have been cached already by buffered reads, page faults with mmap-read or non-direct readahead. To ensure that the on-disk and cached data is consistant for such last cached page, make sure to always invalidate it in zonefs_file_dio_append(). If the invalidation fails, return -EBUSY to userspace to differentiate from IO errors. This invalidation will always be a no-op when the FS block size (device zone write granularity) is equal to the page size (e.g. 4K). Reported-by:

When forwarding is set to 0, frames are typically sent with ttl=1. Move the ttl decrement check below the check for local receive in order to fix packet drops. Reported-by:

rx->sta->amsdu_mesh_control is being passed to ieee80211_amsdu_to_8023s without checking rx->sta. Since it doesn't make sense to accept A-MSDU packets without a sta, simply add a check earlier.
