2022-04-15openvswitch: fix OOB access in reserve_sfa_size()Paolo Valerio1-1/+1
Given a sufficiently large number of actions, while copying and reserving memory for a new action of a new flow, if next_offset is greater than MAX_ACTIONS_BUFSIZE, the function reserve_sfa_size() does not return -EMSGSIZE as expected, but it allocates MAX_ACTIONS_BUFSIZE bytes increasing actions_len by req_size. This can then lead to an OOB write access, especially when further actions need to be copied. Fix it by rearranging the flow action size check.

During ip6gretap device initialization, tunnel->tun_hlen (e.g. 4) is calculated based on old flags (see ip6gre_calc_hlen()); 2. packet_snd() reserves header room for skb A, assuming tunnel->tun_hlen is 4; 3. Later (in clsact Qdisc), the eBPF program sets a new tunnel key for skb A using bpf_skb_set_tunnel_key() (see _ip6gretap_set_tunnel()); 4. __gre6_xmit() detects the new tunnel key, and recalculates "tun_hlen" (e.g. 12) based on new flags (e.g. TUNNEL_KEY and TUNNEL_SEQ); 5. gre_build_header() calls skb_push() with insufficient reserved header room, triggering the BUG. As sugguested by Cong, fix it by moving the call to skb_cow_head() after the recalculation of tun_hlen.

2022-04-15rxrpc: Restore removed timer deletionDavid Howells1-0/+2
A recent patch[1] from Eric Dumazet flipped the order in which the keepalive timer and the keepalive worker were cancelled in order to fix a syzbot reported issue[2]. Unfortunately, this enables the mirror image bug whereby the timer races with rxrpc_exit_net(), restarting the worker after it has been cancelled: CPU 1 CPU 2 =============== ===================== if (rxnet->live) <INTERRUPT> rxnet->live = false; cancel_work_sync(&rxnet->peer_keepalive_work); rxrpc_queue_work(&rxnet->peer_keepalive_work); del_timer_sync(&rxnet->peer_keepalive_timer); Fix this by restoring the removed del_timer_sync() so that we try to remove the timer twice. If the timer runs again, it should see ->live == false and not restart the worker.

2022-04-14dm: allow dm_accept_partial_bio() for dm_io without duplicate biosMike Snitzer1-11/+6
The intent behind commit e6fc9f62ce6e ("dm: flag clones created by __send_duplicate_bios") was to formally disallow the use of dm_accept_partial_bio() where it simply isn't possible -- due to constraint that multiple bios cannot meaningfully update a shared tio->len_ptr. But that commit went too far and disallowed the case where "abormal" IO (e.g. WRITE_ZEROES) is only using a single bio. Fix this by not marking a dm_io with a single dm_target_io (and bio), that happens to be created by __send_duplicate_bios, as DM_TIO_IS_DUPLICATE_BIO. Also remove 'unsigned *len' parameter from alloc_multiple_bios(). This commit fixes a dm_accept_partial_bio() BUG_ON() with dm-zoned when a WRITE_ZEROES bio is issued.

2022-04-14VFS: filename_create(): fix incorrect intent.NeilBrown1-12/+10
When asked to create a path ending '/', but which is not to be a directory (LOOKUP_DIRECTORY not set), filename_create() will never try to create the file. If it doesn't exist, -ENOENT is reported. However, it still passes LOOKUP_CREATE|LOOKUP_EXCL to the filesystems ->lookup() function, even though there is no intent to create. This is misleading and can cause incorrect behaviour. If you try ln -s foo /path/dir/ where 'dir' is a directory on an NFS filesystem which is not currently known in the dcache, this will fail with ENOENT. But as the name is not in the dcache, nfs_lookup gets called with LOOKUP_CREATE|LOOKUP_EXCL and so it returns NULL without performing any lookup, with the expectation that a subsequent call to create the target will be made, and the lookup can be combined with the creation. In the case with a trailing '/' and no LOOKUP_DIRECTORY, that call is never made. Instead filename_create() sees that the dentry is not (yet) positive and returns -ENOENT - even though the directory actually exists. So only set LOOKUP_CREATE|LOOKUP_EXCL if there really is an intent to create, and use the absence of these flags to decide if -ENOENT should be returned. Note that filename_parentat() is only interested in LOOKUP_REVAL, so we split that out and store it in 'reval_flag'. __lookup_hash() then gets reval_flag combined with whatever create flags were determined to be needed.

2022-04-14ice: xsk: check if Rx ring was filled up to the endMaciej Fijalkowski1-1/+6
__ice_alloc_rx_bufs_zc() checks if a number of the descriptors to be allocated would cause the ring wrap. In that case, driver will issue two calls to xsk_buff_alloc_batch() - one that will fill the ring up to the end and the second one that will start with filling descriptors from the beginning of the ring. ice_fill_rx_descs() is a wrapper for taking care of what xsk_buff_alloc_batch() gave back to the driver. It works in a best effort approach, so for example when driver asks for 64 buffers, ice_fill_rx_descs() could assign only 32. Such case needs to be checked when ring is being filled up to the end, because in that situation ntu might not reached the end of the ring. Fix the ring wrap by checking if nb_buffs_extra has the expected value. If not, bump ntu and go directly to tail update.

2022-04-14perf bench: Fix numa bench to fix usage of affinity for machines with #CPUs > 1KAthira Rajeev1-33/+95
The 'perf bench numa' testcase fails on systems with more than 1K CPUs. Testcase: perf bench numa mem -p 1 -t 3 -P 512 -s 100 -zZ0qcm --thp 1 Snippet of code: <<>> perf: bench/numa.c:302: bind_to_node: Assertion `!(ret)' failed. Aborted (core dumped) <<>> bind_to_node() uses "sched_getaffinity" to save the original cpumask and this call is returning EINVAL ((invalid argument). This happens because the default mask size in glibc is 1024. To overcome this 1024 CPUs mask size limitation of cpu_set_t, change the mask size using the CPU_*_S macros ie, use CPU_ALLOC to allocate cpumask, CPU_ALLOC_SIZE for size. Apart from fixing this for "orig_mask", apply same logic to "mask" as well which is used to setaffinity so that mask size is large enough to represent number of possible CPU's in the system. sched_getaffinity is used in one more place in perf numa bench. It is in "bind_to_cpu" function. Apply the same logic there also. Though currently no failure is reported from there, it is ideal to change getaffinity to work with such system configurations having CPU's more than default mask size supported by glibc. Also fix "sched_setaffinity" to use mask size which is large enough to represent number of possible CPU's in the system. Fixed all places where "bind_cpumask" which is part of "struct thread_data" is used such that bind_cpumask works in all configuration.

But it could happen that system has say 48 CPU's, but only number of online CPU's is 0-7. Other CPU's are offlined. Since "g->p.nr_cpus" is 48, so function will go ahead and set bit for CPU 8 also in cpumask ( td->bind_cpumask). bind_to_cpumask function is called to set affinity using sched_setaffinity and the cpumask. Since the CPU8 is not present, set affinity will fail here with EINVAL. Fix this issue by adding a check to make sure that, CPU's provided in the input argument values are online before proceeding further and skip the test. For this, include new helper function "is_cpu_online" in "tools/perf/util/header.c".

We need to take mask into account in the set/get_multiple() callbacks. Use bitmap_replace() instead of bitmap_copy(). Fixes: cb8c474e79be ("gpio: sim: new testing module") Cc: [email protected] Signed-off-by: Bartosz Golaszewski <[email protected]> Reviewed-by: Andy Shevchenko <[email protected]>
2022-04-14net: bcmgenet: Revert "Use stronger register read/writes to assure ordering"Jeremy Linton1-2/+2
It turns out after digging deeper into this bug, that it was being triggered by GCC12 failing to call the bcmgenet_enable_dma() routine. Given that a gcc12 fix has been merged [1] and the genet driver now works properly when built with gcc12, this commit should be reverted.

2022-04-14rtnetlink: Fix handling of disabled L3 stats in RTM_GETSTATS repliesPetr Machata1-0/+3
When L3 stats are disabled, rtnl_offload_xstats_get_size_stats() returns size of 0, which is supposed to be an indication that the corresponding attribute should not be emitted. However, instead, the current code reserves a 0-byte attribute. The reason this does not show up as a citation on a kasan kernel is that netdev_offload_xstats_get(), which is supposed to fill in the data, never ends up getting called, because rtnl_offload_xstats_get_stats() notices that the stats are not actually used and skips the call. Thus a zero-length IFLA_OFFLOAD_XSTATS_L3_STATS attribute ends up in a response, confusing the userspace. Fix by skipping the L3-stats related block in rtnl_offload_xstats_fill().

2022-04-14net: dsa: felix: fix tagging protocol changes with multiple CPU portsVladimir Oltean1-0/+23
When the device tree has 2 CPU ports defined, a single one is active (has any dp->cpu_dp pointers point to it). Yet the second one is still a CPU port, and DSA still calls ->change_tag_protocol on it. On the NXP LS1028A, the CPU ports are ports 4 and 5. Port 4 is the active CPU port and port 5 is inactive. After the following commands: # Initial setting cat /sys/class/net/eno2/dsa/tagging ocelot echo ocelot-8021q > /sys/class/net/eno2/dsa/tagging echo ocelot > /sys/class/net/eno2/dsa/tagging traffic is now broken, because the driver has moved the NPI port from port 4 to port 5, unbeknown to DSA. The problem can be avoided by detecting that the second CPU port is unused, and not doing anything for it. Further rework will be needed when proper support for multiple CPU ports is added. Treat this as a bug and prepare current kernels to work in single-CPU mode with multiple-CPU DT blobs.

Commit 5337824f4dc4 ("net: annotate accesses to queue->trans_start") introduced a new helper, txq_trans_cond_update, to update queue->trans_start using WRITE_ONCE. One snippet in drivers/net/tun.c was missed, as it was introduced roughly at the same time.
