Update type of prof and prof_mask fields in nix_as_enq_req from u64 to struct nix_bandprof_s, which is 128 bits wide. This is to address warnings with compiling with gcc-12 W=1 regarding string fortification. Although the union of which these fields are a member is 128bits wide, and thus writing a 128bit entity is safe, the compiler flags a problem as the field being written is only 64 bits wide.

currently, users can skip individual test cases by means of writing "skip": "yes" in the scenario file. Extend this functionality, introducing 'dependsOn': it's optional property like "skip", but the value contains a command (for example, a probe on iproute2 to check if it supports a specific feature). If such property is present, tdc executes that command and skips the test when the return value is non-zero. Reviewed-by:

This selftest was introduced recently in the commit cited below. It misses several check_err() invocations to actually verify that the previous command succeeded. When these are added, the first one fails, because besides the addresses added by hand, there can be a link-local address added by the kernel. Adjust the check to expect at least three addresses instead of exactly three, and add the missing check_err's. Furthermore, the explanatory comments assume that the address with no protocol is $addr2, when in fact it is $addr3. Update the comments.

We have the following code paths: Host FDB (unicast RX filtering): dsa_port_standalone_host_fdb_add() dsa_port_bridge_host_fdb_add() | | +--------------+ +------------+ | | v v dsa_port_host_fdb_add() dsa_port_standalone_host_fdb_del() dsa_port_bridge_host_fdb_del() | | +--------------+ +------------+ | | v v dsa_port_host_fdb_del() Host MDB (multicast RX filtering): dsa_port_standalone_host_mdb_add() dsa_port_bridge_host_mdb_add() | | +--------------+ +------------+ | | v v dsa_port_host_mdb_add() dsa_port_standalone_host_mdb_del() dsa_port_bridge_host_mdb_del() | | +--------------+ +------------+ | | v v dsa_port_host_mdb_del() The logic added by commit 5e8a1e03 ("net: dsa: install secondary unicast and multicast addresses as host FDB/MDB") zeroes out db.bridge.num if the switch doesn't support ds->fdb_isolation (the majority doesn't). This is done for a reason explained in commit c2693363 ("net: dsa: request drivers to perform FDB isolation"). Taking a single code path as example - dsa_port_host_fdb_add() - the others are similar - the problem is that this function handles: - DSA_DB_PORT databases, when called from dsa_port_standalone_host_fdb_add() - DSA_DB_BRIDGE databases, when called from dsa_port_bridge_host_fdb_add() So, if dsa_port_host_fdb_add() were to make any change on the "bridge.num" attribute of the database, this would only be correct for a DSA_DB_BRIDGE, and a type confusion for a DSA_DB_PORT bridge. However, this bug is without consequences, for 2 reasons: - dsa_port_standalone_host_fdb_add() is only called from code which is (in)directly guarded by dsa_switch_supports_uc_filtering(ds), and that function only returns true if ds->fdb_isolation is set. So, the code only executed for DSA_DB_BRIDGE databases. - Even if the code was not dead for DSA_DB_PORT, we have the following memory layout: struct dsa_bridge { struct net_device *dev; unsigned int num; bool tx_fwd_offload; refcount_t refcount; }; struct dsa_db { enum dsa_db_type type; union { const struct dsa_port *dp; // DSA_DB_PORT struct dsa_lag lag; struct dsa_bridge bridge; // DSA_DB_BRIDGE }; }; So, the zeroization of dsa_db :: bridge :: num on a dsa_db structure of type DSA_DB_PORT would access memory which is unused, because we only use dsa_db :: dp for DSA_DB_PORT, and this is mapped at the same address with dsa_db :: dev for DSA_DB_BRIDGE, thanks to the union definition. It is correct to fix up dsa_db :: bridge :: num only from code paths that come from the bridge / switchdev, so move these there. Signed-off-by:Vladimir Oltean <vladimir.oltean@nxp.com> Reviewed-by:

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.

drm_gem_prime_mmap() takes a reference on the GEM object, but before that drm_gem_mmap_obj() already takes a reference, which will be leaked as only one reference is dropped when the mapping is closed. Drop the extra reference when dma_buf_mmap() succeeds. Cc: stable@vger.kernel.org Signed-off-by:

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:

Eric Dumazet says: ==================== net: rps/rfs improvements Jason Xing attempted to optimize napi_schedule_rps() by avoiding unneeded NET_RX_SOFTIRQ raises: [1], [2] This is quite complex to implement properly. I chose to implement the idea, and added a similar optimization in ____napi_schedule() Overall, in an intensive RPC workload, with 32 TX/RX queues with RFS I was able to observe a ~10% reduction of NET_RX_SOFTIRQ invocations. While this had no impact on throughput or cpu costs on this synthetic benchmark, we know that firing NET_RX_SOFTIRQ from softirq handler can force __do_softirq() to wakeup ksoftirqd when need_resched() is true. This can have a latency impact on stressed hosts.
