Commit f49843afde (selftests/bpf: Add tests for css_task iter combining with cgroup iter) added a test which demonstrates how css_task iter can be combined with cgroup iter. That test used bpf_cgroup_from_id() to convert bpf_iter__cgroup->cgroup to a trusted ptr which is pointless now, since with the previous fix, we can get a trusted cgroup directly from bpf_iter__cgroup.

2023-11-07bpf: Let verifier consider {task,cgroup} is trusted in bpf_iter_regChuyi Zhou
BTF_TYPE_SAFE_TRUSTED(struct bpf_iter__task) in verifier.c wanted to teach BPF verifier that bpf_iter__task -> task is a trusted ptr. But it doesn't work well. The reason is, bpf_iter__task -> task would go through btf_ctx_access() which enforces the reg_type of 'task' is ctx_arg_info->reg_type, and in task_iter.c, we actually explicitly declare that the ctx_arg_info->reg_type is PTR_TO_BTF_ID_OR_NULL. Actually we have a previous case like this[1] where PTR_TRUSTED is added to the arg flag for map_iter. This patch sets ctx_arg_info->reg_type is PTR_TO_BTF_ID_OR_NULL | PTR_TRUSTED in task_reg_info. Similarly, bpf_cgroup_reg_info -> cgroup is also PTR_TRUSTED since we are under the protection of cgroup_mutex and we would check cgroup_is_dead() in __cgroup_iter_seq_show(). This patch is to improve the user experience of the newly introduced bpf_iter_css_task kfunc before hitting the mainline. The Fixes tag is pointing to the commit introduced the bpf_iter_css_task kfunc.

2023-11-07net: phylink: initialize carrier state at creationKlaus Kudielka
Background: Turris Omnia (Armada 385); eth2 (mvneta) connected to SFP bus; SFP module is present, but no fiber connected, so definitely no carrier. After booting, eth2 is down, but netdev LED trigger surprisingly reports link active. Then, after "ip link set eth2 up", the link indicator goes away - as I would have expected it from the beginning. It turns out, that the default carrier state after netdev creation is "carrier ok". Some ethernet drivers explicitly call netif_carrier_off during probing, others (like mvneta) don't - which explains the current behaviour: only when the device is brought up, phylink_start calls netif_carrier_off. Fix this for all drivers using phylink, by calling netif_carrier_off in phylink_create.

Filippo Storniolo says: ==================== vsock: fix server prevents clients from reconnecting This patch series introduce fix and tests for the following vsock bug: If the same remote peer, using the same port, tries to connect to a server on a listening port more than once, the server will reject the connection, causing a "connection reset by peer" error on the remote peer. This is due to the presence of a dangling socket from a previous connection in both the connected and bound socket lists.

2023-11-07vsock/virtio: remove socket from connected/bound list on shutdownFilippo Storniolo
If the same remote peer, using the same port, tries to connect to a server on a listening port more than once, the server will reject the connection, causing a "connection reset by peer" error on the remote peer. This is due to the presence of a dangling socket from a previous connection in both the connected and bound socket lists. The inconsistency of the above lists only occurs when the remote peer disconnects and the server remains active. This bug does not occur when the server socket is closed: virtio_transport_release() will eventually schedule a call to virtio_transport_do_close() and the latter will remove the socket from the bound and connected socket lists and clear the sk_buff. However, virtio_transport_do_close() will only perform the above actions if it has been scheduled, and this will not happen if the server is processing the shutdown message from a remote peer. To fix this, introduce a call to vsock_remove_sock() when the server is handling a client disconnect. This is to remove the socket from the bound and connected socket lists without clearing the sk_buff.

2023-11-07tcp: Fix -Wc23-extensions in tcp_options_write()Nathan Chancellor
Clang warns (or errors with CONFIG_WERROR=y) when CONFIG_TCP_AO is set: net/ipv4/tcp_output.c:663:2: error: label at end of compound statement is a C23 extension [-Werror,-Wc23-extensions] 663 | } | ^ 1 error generated. On earlier releases (such as clang-11, the current minimum supported version for building the kernel) that do not support C23, this was a hard error unconditionally: net/ipv4/tcp_output.c:663:2: error: expected statement } ^ 1 error generated. While adding a semicolon after the label would resolve this, it is more in line with the kernel as a whole to refactor this block into a standalone function, which means the goto a label construct can just be replaced with a return statement. Do so to resolve the warning.

2023-11-07tg3: Fix the TX ring stallAlex Pakhunov
The TX ring maintained by the tg3 driver can end up in the state, when it has packets queued for sending but the NIC hardware is not informed, so no progress is made. This leads to a multi-second interruption in network traffic followed by dev_watchdog() firing and resetting the queue. The specific sequence of steps is: 1. tg3_start_xmit() is called at least once and queues packet(s) without updating tnapi->prodmbox (netdev_xmit_more() returns true) 2. tg3_start_xmit() is called with an SKB which causes tg3_tso_bug() to be called. 3. tg3_tso_bug() determines that the SKB is too large, ... if (unlikely(tg3_tx_avail(tnapi) <= frag_cnt_est)) { ... stops the queue, and returns NETDEV_TX_BUSY: netif_tx_stop_queue(txq); ... if (tg3_tx_avail(tnapi) <= frag_cnt_est) return NETDEV_TX_BUSY; 4. Since all tg3_tso_bug() call sites directly return, the code updating tnapi->prodmbox is skipped. 5. The queue is stuck now. tg3_start_xmit() is not called while the queue is stopped. The NIC is not processing new packets because tnapi->prodmbox wasn't updated. tg3_tx() is not called by tg3_poll_work() because the all TX descriptions that could be freed has been freed: /* run TX completion thread */ if (tnapi->hw_status->idx[0].tx_consumer != tnapi->tx_cons) { tg3_tx(tnapi); 6. Eventually, dev_watchdog() fires triggering a reset of the queue. This fix makes sure that the tnapi->prodmbox update happens regardless of the reason tg3_start_xmit() returned.

While inotify is availabe on all filesystems, fanotify currently isn't. In order to support fanotify on all filesystems two things are needed: (1) all filesystems need to support AT_HANDLE_FID (2) all filesystems need to report a non-zero f_fsid This contains (1) and allows filesystems to encode non-decodable file handlers for fanotify without implementing any exportfs operations by encoding a file id of type FILEID_INO64_GEN from i_ino and i_generation. Filesystems that want to opt out of encoding non-decodable file ids for fanotify that don't support NFS export can do so by providing an empty export_operations struct. This also partially addresses (2) by generating f_fsid for simple filesystems as well as freevxfs. Remaining filesystems will be dealt with by separate patches. Finally, this contains the patch from the current exportfs maintainers which moves exportfs under vfs with Chuck, Jeff, and Amir as maintainers and vfs.git as tree" * tag 'vfs-6.7.fsid' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs: MAINTAINERS: create an entry for exportfs fs: fix build error with CONFIG_EXPORTFS=m or not defined freevxfs: derive f_fsid from bdev->bd_dev fs: report f_fsid from s_dev for "simple" filesystems exportfs: support encoding non-decodeable file handles by default exportfs: define FILEID_INO64_GEN* file handle types exportfs: make ->encode_fh() a mandatory method for NFS export exportfs: add helpers to check if filesystem can encode/decode file handles

2023-11-06ice: Fix VF-VF direction matching in drop rule in switchdevMarcin Szycik
When adding a drop rule on a VF, rule direction is not being set, which results in it always being set to ingress (ICE_ESWITCH_FLTR_INGRESS equals 0). Because of this, drop rules added on port representors don't match any packets. To fix it, set rule direction in drop action to egress when netdev is a port representor, otherwise set it to ingress.

This patch re-fix the issues mentioned by commit 22a825c541d7 ("net/smc: fix NULL sndbuf_desc in smc_cdc_tx_handler()"). Blocking sending message do solve the issues though, but it also prevents the peer to receive the final message. Besides, in logic, whether the sndbuf_desc is NULL or not have no impact on the processing of cdc message sending. Hence that, this patch allows the cdc message sending but to check the sndbuf_desc with care in smc_cdc_tx_handler().

2023-11-06tcp: Fix SYN option room calculation for TCP-AO.Kuniyuki Iwashima
When building SYN packet in tcp_syn_options(), MSS, TS, WS, and SACKPERM are used without checking the remaining bytes in the options area. To keep that logic as is, we limit the TCP-AO MAC length in tcp_ao_parse_crypto(). Currently, the limit is calculated as below. MAX_TCP_OPTION_SPACE - TCPOLEN_TSTAMP_ALIGNED - TCPOLEN_WSCALE_ALIGNED - TCPOLEN_SACKPERM_ALIGNED This looks confusing as (1) we pack SACKPERM into the leading 2-bytes of the aligned 12-bytes of TS and (2) TCPOLEN_MSS_ALIGNED is not used. Fortunately, the calculated limit is not wrong as TCPOLEN_SACKPERM_ALIGNED and TCPOLEN_MSS_ALIGNED are the same value. However, we should use the proper constant in the formula.
