2022-05-25selftests/net: enable lo.accept_local in psock_snd testluyun1-0/+2
The psock_snd test sends and receives packets over loopback, and the test results depend on parameter settings: Set rp_filter=0, or set rp_filter=1 and accept_local=1 so that the test will pass. Otherwise, this test will fail with Resource temporarily unavailable: sudo ./psock_snd.sh dgram tx: 128 rx: 142 ./psock_snd: recv: Resource temporarily unavailable For most distro kernel releases(like Ubuntu or Centos), the parameter rp_filter is enabled by default, so it's necessary to enable the parameter lo.accept_local in psock_snd test. And this test runs inside a netns, changing a sysctl is fine.

2022-05-25net: ethernet: ti: am65-cpsw: Fix fwnode passed to phylink_create()Siddharth Vadapalli1-1/+4
am65-cpsw-nuss driver incorrectly uses fwnode member of common ethernet device's "struct device_node" instead of using fwnode member of the port's "struct device_node" in phylink_create(). This results in all ports having the same phy data when there are multiple ports with their phy properties populated in their respective nodes rather than the common ethernet device node. Fix it here by using fwnode member of the port's node.

Taehee Yoo says: ==================== amt: fix several bugs This patchset fixes several bugs in amt module First patch fixes typo. Second patch fixes wrong return value of amt_update_handler(). A relay finds a tunnel if it receives an update message from the gateway. If it can't find a tunnel, amt_update_handler() should return an error, not success. But it always returns success. Third patch fixes a possible memory leak in amt_rcv(). A skb would not be freed if an amt interface doesn't have a socket. ==================== Link: https://lore.kernel.org/r/[email protected] Signed-off-by: Jakub Kicinski <[email protected]>

2022-05-25Merge tag 'xfs-5.19-for-linus' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linuxLinus Torvalds104-2675/+4689
Pull xfs updates from Dave Chinner: "This is a big update with lots of new code. The summary below them all, so I'll just touch on teh higlights. The two main new features are Large Extent Counts and Logged Attribute Replay - these are two new foundational features that we are building more complex future features on top of. For upcoming functionality, we need to be able to store hundreds of millions of xattrs per inode. The Large Extent Count feature removes the limits that prevent this scale of xattr storage, and while we were modifying the on disk extent count format we also increased the number of data extents we support per inode from 2^32 to 2^47. We also need to be able to modify xattrs as part of larger atomic transactions rather than as standalone transactions. The Logged Attribute Replay feature introduces the infrastructure that allows us to use intents to record the attribute modifications in the journal before we start them, hence allowing other atomic transactions to log attribute modification intents and then defer the actual modification to later. If we then crash, log recovery then guarantees that the attribute is replayed in the context of the atomic transaction that logged the intent. A significant chunk of the commits in this merge are for the base attribute replay functionality along with fixes, improvements and cleanups related to this new functioanlity. Allison deserves a big round of thanks for her ongoing work to get this functionality into XFS. There are also many other smaller changes and improvements, so overall this is one of the bigger XFS merge requests in some time. I will be following up next week with another smaller pull request - we already have another round of fixes and improvements to the logged attribute replay functionality just about ready to go. They'll soak and test over the next week, and I'll send a pull request for them near the end of the merge window. Summary: - support for printk message indexing. - large extent counts to provide support for up to 2^47 data extents and 2^32 attribute extents, allowing us to scale beyond 4 billion data extents to billions of xattrs per inode. - conversion of various flags fields to be consistently declared as unsigned bit fields. - improvements to realtime extent accounting and converts them to per-cpu counters to match all the other block and inode accounting. - reworks core log formatting code to reduce iterations, have a shorter, cleaner fast path and generally be easier to understand and maintain. - improvements to rmap btree searches that reduce overhead by up to 30% resulting in xfs_scrub runtime reductions of 15%. - improvements to reflink that remove the size limitations in remapping operations and greatly reduce the size of transaction reservations. - reworks the minimum log size calculations to allow us to change transaction reservations without changing the minimum supported log size. - removal of quota warning support as it has never been used on Linux. - intent whiteouts to allow us to cancel intents that are completed entirely in memory rather than having use CPU and disk bandwidth formatting and writing them into the journal when it is not necessary. This makes rmap, reflink and extent freeing slightly more efficient, but provides massive improvements for.... - Logged Attribute Replay feature support. This is a fundamental change to the way we modify attributes, laying the foundation for future integration of attribute modifications as part of other atomic transactional operations the filesystem performs. - Lots of cleanups and fixes for the logged attribute replay functionality" * tag 'xfs-5.19-for-linus' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux: (124 commits) xfs: can't use kmem_zalloc() for attribute buffers xfs: detect empty attr leaf blocks in xfs_attr3_leaf_verify xfs: ATTR_REPLACE algorithm with LARP enabled needs rework xfs: use XFS_DA_OP flags in deferred attr ops xfs: remove xfs_attri_remove_iter xfs: switch attr remove to xfs_attri_set_iter xfs: introduce attr remove initial states into xfs_attr_set_iter xfs: xfs_attr_set_iter() does not need to return EAGAIN xfs: clean up final attr removal in xfs_attr_set_iter xfs: remote xattr removal in xfs_attr_set_iter() is conditional xfs: XFS_DAS_LEAF_REPLACE state only needed if !LARP xfs: split remote attr setting out from replace path xfs: consolidate leaf/node states in xfs_attr_set_iter xfs: kill XFS_DAC_LEAF_ADDNAME_INIT xfs: separate out initial attr_set states xfs: don't set quota warning values xfs: remove warning counters from struct xfs_dquot_res xfs: remove quota warning limit from struct xfs_quota_limits xfs: rework deferred attribute operation setup xfs: make xattri_leaf_bp more useful ...

The direct trampoline and graph coexistence test sets global_ops to trace only 'trace_selftest_dynamic_test_func', but does not reset it after the test is completed, resulting in the function filter being set already after the system starts. Although it can be reset through the tracefs interface, it is more or less confusing to the user, and we should reset it to trace all functions after the trampoline/graph test completes.

In __sanitizer_cov_trace_pc(), previously we write pc before updating pos. However, some early interrupt code could bypass check_kcov_mode() check and invoke __sanitizer_cov_trace_pc(). If such interrupt is raised between writing pc and updating pos, the pc could be overitten by the recursive __sanitizer_cov_trace_pc(). As suggested by Dmitry, we cold update pos before writing pc to avoid such interleaving. Apply the same change to write_comp_data().

2022-05-25ocfs2: dlmfs: fix error handling of user_dlm_destroy_lockJunxiao Bi via Ocfs2-devel1-1/+15
When user_dlm_destroy_lock failed, it didn't clean up the flags it set before exit. For USER_LOCK_IN_TEARDOWN, if this function fails because of lock is still in used, next time when unlink invokes this function, it will return succeed, and then unlink will remove inode and dentry if lock is not in used(file closed), but the dlm lock is still linked in dlm lock resource, then when bast come in, it will trigger a panic due to user-after-free. See the following panic call trace. To fix this, USER_LOCK_IN_TEARDOWN should be reverted if fail. And also error should be returned if USER_LOCK_IN_TEARDOWN is set to let user know that unlink fail. For the case of ocfs2_dlm_unlock failure, besides USER_LOCK_IN_TEARDOWN, USER_LOCK_BUSY is also required to be cleared. Even though spin lock is released in between, but USER_LOCK_IN_TEARDOWN is still set, for USER_LOCK_BUSY, if before every place that waits on this flag, USER_LOCK_IN_TEARDOWN is checked to bail out, that will make sure no flow waits on the busy flag set by user_dlm_destroy_lock(), then we can simplely revert USER_LOCK_BUSY when ocfs2_dlm_unlock fails. Fix user_dlm_cluster_lock() which is the only function not following this.

2022-05-25ocfs2: dlmfs: don't clear USER_LOCK_ATTACHED when destroying lockJunxiao Bi1-1/+0
The following function is the only place that checks USER_LOCK_ATTACHED. This flag is set when lock request is granted through user_ast() and only the following function will clear it. Checking of this flag here is to make sure ocfs2_dlm_unlock is not issued if this lock is never granted. For example, lock file is created and then get removed, open file never happens. Clearing the flag here is not necessary because this is the only function that checks it, if another flow is executing user_dlm_destroy_lock(), it will bail out at the beginning because of USER_LOCK_IN_TEARDOWN and never check USER_LOCK_ATTACHED. Drop the clear, so we don't need take care of it for the following error handling patch. int user_dlm_destroy_lock(struct user_lock_res *lockres) { ... status = 0; if (!(lockres->l_flags & USER_LOCK_ATTACHED)) { spin_unlock(&lockres->l_lock); goto bail; } lockres->l_flags &= ~USER_LOCK_ATTACHED; lockres->l_flags |= USER_LOCK_BUSY; spin_unlock(&lockres->l_lock); status = ocfs2_dlm_unlock(conn, &lockres->l_lksb, DLM_LKF_VALBLK); if (status) { user_log_dlm_error("ocfs2_dlm_unlock", status, lockres); goto bail; } ... } V1 discussion with Joseph: https://lore.kernel.org/all/[email protected]/T/ Link: https://lkml.kernel.org/r/[email protected] Signed-off-by: Junxiao Bi <[email protected]> Reviewed-by: Joseph Qi <[email protected]> Cc: Mark Fasheh <[email protected]> Cc: Joel Becker <[email protected]> Cc: Junxiao Bi <[email protected]> Cc: Changwei Ge <[email protected]> Cc: Gang He <[email protected]> Cc: Jun Piao <[email protected]> Signed-off-by: Andrew Morton <[email protected]>

BPF --- - Add libbpf support for User Statically-Defined Tracing (USDTs). - Speed up symbol resolution for kprobes multi-link attachments. - Support storing typed pointers to referenced and unreferenced objects in BPF maps. - Add support for BPF link iterator. - Introduce access to remote CPU map elements in BPF per-cpu map. - Allow middle-of-the-road settings for the kernel.unprivileged_bpf_disabled sysctl. - Implement basic types of dynamic pointers e.g. to allow for dynamically sized ringbuf reservations without extra memory copies. Protocols --------- - Retire port only listening_hash table, add a second bind table hashed by port and address. Avoid linear list walk when binding to very popular ports (e.g. 443). - Add bridge FDB bulk flush filtering support allowing user space to remove all FDB entries matching a condition. - Introduce accept_unsolicited_na sysctl for IPv6 to implement router-side changes for RFC9131. - Support for MPTCP path manager in user space. - Add MPTCP support for fallback to regular TCP for connections that have never connected additional subflows or transmitted out-of-sequence data (partial support for RFC8684 fallback). - Avoid races in MPTCP-level window tracking, stabilize and improve throughput. - Support lockless operation of GRE tunnels with seq numbers enabled. - WiFi support for host based BSS color collision detection. - Add support for SO_TXTIME/SCM_TXTIME on CAN sockets. - Support transmission w/o flow control in CAN ISOTP (ISO 15765-2). - Support zero-copy Tx with TLS 1.2 crypto offload (sendfile). - Allow matching on the number of VLAN tags via tc-flower. - Add tracepoint for tcp_set_ca_state(). Driver API ---------- - Improve error reporting from classifier and action offload. - Add support for listing line cards in switches (devlink). - Add helpers for reporting page pool statistics with ethtool -S. - Add support for reading clock cycles when using PTP virtual clocks, instead of having the driver convert to time before reporting. This makes it possible to report time from different vclocks. - Support configuring low-latency Tx descriptor push via ethtool. - Separate Clause 22 and Clause 45 MDIO accesses more explicitly.

The cephfs kernel client started to show the message: ceph: mds0 session blocklisted when mounting a filesystem. This is due to the fact that the session messages are being incorrectly decoded: the skip needs to take into account the 'len'. While there, fixed some whitespaces too.

2022-05-25ceph: try to queue a writeback if revoking failsXiubo Li1-4/+24
If the pagecaches writeback just finished and the i_wrbuffer_ref reaches zero it will try to trigger ceph_check_caps(). But if just before ceph_check_caps() the i_wrbuffer_ref could be increased again by mmap/cache write, then the Fwb revoke will fail. We need to try to queue a writeback in this case instead of triggering the writeback by BDI's delayed work per 5 seconds.

2022-05-25ceph: fix statfs for subdir mountsLuís Henriques3-13/+36
When doing a mount using as base a directory that has 'max_bytes' quotas statfs uses that value as the total; if a subdirectory is used instead, the same 'max_bytes' too in statfs, unless there is another quota set. Unfortunately, if this subdirectory only has the 'max_files' quota set, then statfs uses the filesystem total. Fix this by making sure we only lookup realms that contain the 'max_bytes' quota.

2022-05-25ceph: fix possible deadlock when holding Fwb to get inline_dataXiubo Li1-14/+19
1, mount with wsync. 2, create a file with O_RDWR, and the request was sent to mds.0: ceph_atomic_open()--> ceph_mdsc_do_request(openc) finish_open(file, dentry, ceph_open)--> ceph_open()--> ceph_init_file()--> ceph_init_file_info()--> ceph_uninline_data()--> { ... if (inline_version == 1 || /* initial version, no data */ inline_version == CEPH_INLINE_NONE) goto out_unlock; ... } The inline_version will be 1, which is the initial version for the new create file. And here the ci->i_inline_version will keep with 1, it's buggy. 3, buffer write to the file immediately: ceph_write_iter()--> ceph_get_caps(file, need=Fw, want=Fb, ...); generic_perform_write()--> a_ops->write_begin()--> ceph_write_begin()--> netfs_write_begin()--> netfs_begin_read()--> netfs_rreq_submit_slice()--> netfs_read_from_server()--> rreq->netfs_ops->issue_read()--> ceph_netfs_issue_read()--> { ... if (ci->i_inline_version != CEPH_INLINE_NONE && ceph_netfs_issue_op_inline(subreq)) return; ... } ceph_put_cap_refs(ci, Fwb); The ceph_netfs_issue_op_inline() will send a getattr(Fsr) request to mds.1. 4, then the mds.1 will request the rd lock for CInode::filelock from the auth mds.0, the mds.0 will do the CInode::filelock state transation from excl --> sync, but it need to revoke the Fxwb caps back from the clients. While the kernel client has aleady held the Fwb caps and waiting for the getattr(Fsr). It's deadlock!

2022-05-25ceph: try to choose the auth MDS if possible for getattrXiubo Li3-2/+29
If any 'x' caps is issued we can just choose the auth MDS instead of the random replica MDSes. Because only when the Locker is in LOCK_EXEC state will the loner client could get the 'x' caps. And if we send the getattr requests to any replica MDS it must auth pin and tries to rdlock from the auth MDS, and then the auth MDS need to do the Locker state transition to LOCK_SYNC. And after that the lock state will change back. This cost much when doing the Locker state transition and usually will need to revoke caps from clients.

2022-05-25ceph: flush the mdlog for filesystem syncXiubo Li1-6/+27
Before waiting for a request's safe reply, we will send the mdlog flush request to the relevant MDS. And this will also flush the mdlog for all the other unsafe requests in the same session, so we can record the last session and no need to flush mdlog again in the next loop. But there still have cases that it may send the mdlog flush requst twice or more, but that should be not often.

2022-05-25ceph: replace usage of found with dedicated list iterator variableJakob Koschel1-17/+15
To move the list iterator variable into the list_for_each_entry_*() macro in the future it should be avoided to use the list iterator variable after the loop body. To *never* use the list iterator variable after the loop it was concluded to use a separate iterator variable instead of a found boolean. This removes the need to use a found variable and simply checking if the variable was set, can determine if the break/goto was hit.
