Currently turning on DEBUG_INFO_SPLIT when DEBUG_INFO_BTF is also enabled will produce invalid btf file, since gen_btf function in link-vmlinux.sh script doesn't handle *.dwo files. Enabling DEBUG_INFO_REDUCED will also produce invalid btf file, and using GCC_PLUGIN_RANDSTRUCT with BTF makes no sense.

Florian Westphal says: ==================== mptcp: various bugfixes and improvements This series contains the following mptcp bug fixes: 1. Fix crash on tcp fallback when userspace doesn't provide a 'struct sockaddr' to accept(). 2. Close mptcp socket only when all subflows have closed, not just the first. 3. avoid stream data corruption when we'd receive identical mapping at the exact same time on multiple subflows. 4. Fix "fn parameter not described" kerneldoc warnings. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

mptcp_subflow_data_available() is commonly called via ssk->sk_data_ready(), in this case the mptcp socket lock cannot be acquired. Therefore, while we can safely discard subflow data that was already received up to msk->ack_seq, we cannot be sure that 'subflow->data_avail' will still be valid at the time userspace wants to read the data -- a previous read on a different subflow might have carried this data already. In that (unlikely) event, msk->ack_seq will have been updated and will be ahead of the subflow dsn. We can check for this condition and skip/resync to the expected sequence number.

This is needed at least until proper MPTCP-Level fin/reset signalling gets added: We wake parent when a subflow changes, but we should do this only when all subflows have closed, not just one. Schedule the mptcp worker and tell it to check eof state on all subflows. Only flag mptcp socket as closed and wake userspace processes blocking in poll if all subflows have closed.

Christoph Paasch reports following crash: general protection fault [..] CPU: 0 PID: 2874 Comm: syz-executor072 Not tainted 5.6.0-rc5 #62 RIP: 0010:__pv_queued_spin_lock_slowpath kernel/locking/qspinlock.c:471 [..] queued_spin_lock_slowpath arch/x86/include/asm/qspinlock.h:50 [inline] do_raw_spin_lock include/linux/spinlock.h:181 [inline] spin_lock_bh include/linux/spinlock.h:343 [inline] __mptcp_flush_join_list+0x44/0xb0 net/mptcp/protocol.c:278 mptcp_shutdown+0xb3/0x230 net/mptcp/protocol.c:1882 [..] Problem is that mptcp_shutdown() socket isn't an mptcp socket, its a plain tcp_sk. Thus, trying to access mptcp_sk specific members accesses garbage. Root cause is that accept() returns a fallback (tcp) socket, not an mptcp one. There is code in getpeername to detect this and override the sockets stream_ops. But this will only run when accept() caller provided a sockaddr struct. "accept(fd, NULL, 0)" will therefore result in mptcp stream ops, but with sock->sk pointing at a tcp_sk. Update the existing fallback handling to detect this as well. Moreover, mptcp_shutdown did not have fallback handling, and mptcp_poll did it too late so add that there as well.

cxgb4_update_mac_filt() earlier requests firmware to add a new MAC address into MPS TCAM. The MPS TCAM index returned by firmware is stored in pi->xact_addr_filt. However, the saved MPS TCAM index gets overwritten again with the return value of cxgb4_update_mac_filt(), which is wrong. When trying to update to another MAC address later, the wrong MPS TCAM index is sent to firmware, which causes firmware to return error, because it's not the same MPS TCAM index that firmware had sent earlier to driver. So, fix by removing the wrong overwrite being done after call to cxgb4_update_mac_filt().

Although we intentionally use an ordered workqueue for all tc filter works, the ordering is not guaranteed by RCU work, given that tcf_queue_work() is esstenially a call_rcu(). This problem is demostrated by Thomas: CPU 0: tcf_queue_work() tcf_queue_work(&r->rwork, tcindex_destroy_rexts_work); -> Migration to CPU 1 CPU 1: tcf_queue_work(&p->rwork, tcindex_destroy_work); so the 2nd work could be queued before the 1st one, which leads to a free-after-free. Enforcing this order in RCU work is hard as it requires to change RCU code too. Fortunately we can workaround this problem in tcindex filter by taking a temporary refcnt, we only refcnt it right before we begin to destroy it. This simplifies the code a lot as a full refcnt requires much more changes in tcindex_set_parms().

Pull SELinux updates from Paul Moore: "We've got twenty SELinux patches for the v5.7 merge window, the highlights are below: - Deprecate setting /sys/fs/selinux/checkreqprot to 1. This flag was originally created to deal with legacy userspace and the READ_IMPLIES_EXEC personality flag. We changed the default from 1 to 0 back in Linux v4.4 and now we are taking the next step of deprecating it, at some point in the future we will take the final step of rejecting 1. - Allow kernfs symlinks to inherit the SELinux label of the parent directory. In order to preserve backwards compatibility this is protected by the genfs_seclabel_symlinks SELinux policy capability. - Optimize how we store filename transitions in the kernel, resulting in some significant improvements to policy load times. - Do a better job calculating our internal hash table sizes which resulted in additional policy load improvements and likely general SELinux performance improvements as well. - Remove the unused initial SIDs (labels) and improve how we handle initial SIDs. - Enable per-file labeling for the bpf filesystem. - Ensure that we properly label NFS v4.2 filesystems to avoid a temporary unlabeled condition. - Add some missing XFS quota command types to the SELinux quota access controls. - Fix a problem where we were not updating the seq_file position index correctly in selinuxfs. - We consolidate some duplicated code into helper functions. - A number of list to array conversions. - Update Stephen Smalley's email address in MAINTAINERS" * tag 'selinux-pr-20200330' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/selinux: selinux: clean up indentation issue with assignment statement NFS: Ensure security label is set for root inode MAINTAINERS: Update my email address selinux: avtab_init() and cond_policydb_init() return void selinux: clean up error path in policydb_init() selinux: remove unused initial SIDs and improve handling selinux: reduce the use of hard-coded hash sizes selinux: Add xfs quota command types selinux: optimize storage of filename transitions selinux: factor out loop body from filename_trans_read() security: selinux: allow per-file labeling for bpffs selinux: generalize evaluate_cond_node() selinux: convert cond_expr to array selinux: convert cond_av_list to array selinux: convert cond_list to array selinux: sel_avc_get_stat_idx should increase position index selinux: allow kernfs symlinks to inherit parent directory context selinux: simplify evaluate_cond_node() Documentation,selinux: deprecate setting checkreqprot to 1 selinux: move status variables out of selinux_ss

Pull audit updates from Paul Moore: "We've got two audit patches for the v5.7 merge window with a stellar 14 lines changed between the two patches. The patch descriptions are far more lengthy than the patches themselves, which is a very good thing for patches this size IMHO. The patches pass our test suites and a quick summary is below: - Stop logging inode information when updating an audit file watch. Since we are not changing the inode, or the fact that we are watching the associated file, the inode information is just noise that we can do without. - Fix a problem where mandatory audit records were missing their accompanying audit records (e.g. SYSCALL records were missing). The missing records often meant that we didn't have the necessary context to understand what was going on when the event occurred" * tag 'audit-pr-20200330' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/audit: audit: trigger accompanying records when no rules present audit: CONFIG_CHANGE don't log internal bookkeeping as an event

Pull gfs2 updates from Bob Peterson: "We've got a lot of patches (39) for this merge window. Most of these patches are related to corruption that occurs when journals are replayed. For example: 1. A node fails while writing to the file system. 2. Other nodes use the metadata that was once used by the failed node. 3. When the node returns to the cluster, its journal is replayed, but the older metadata blocks overwrite the changes from step 2.
