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. Summary: - Fixed the recovery sequence to prevent corruption during journal replay. - Many bug fixes found during recovery testing. - New improved file system withdraw sequence. - Fixed how resource group buffers are managed. - Fixed how metadata revokes are tracked and written. - Improve processing of IO errors hit by daemons like logd and quotad. - Improved error checking in metadata writes. - Fixed how qadata quota data structures are managed" * tag 'gfs2-for-5.7' of git://git.kernel.org/pub/scm/linux/kernel/git/gfs2/linux-gfs2: (39 commits) gfs2: Fix oversight in gfs2_ail1_flush gfs2: change from write to read lock for sd_log_flush_lock in journal replay gfs2: instrumentation wrt ail1 stuck gfs2: don't lock sd_log_flush_lock in try_rgrp_unlink gfs2: Remove unnecessary gfs2_qa_{get,put} pairs gfs2: Split gfs2_rsqa_delete into gfs2_rs_delete and gfs2_qa_put gfs2: Change inode qa_data to allow multiple users gfs2: eliminate gfs2_rsqa_alloc in favor of gfs2_qa_alloc gfs2: Switch to list_{first,last}_entry gfs2: Clean up inode initialization and teardown gfs2: Additional information when gfs2_ail1_flush withdraws gfs2: leaf_dealloc needs to allocate one more revoke gfs2: allow journal replay to hold sd_log_flush_lock gfs2: don't allow releasepage to free bd still used for revokes gfs2: flesh out delayed withdraw for gfs2_log_flush gfs2: Do proper error checking for go_sync family of glops functions gfs2: Don't demote a glock until its revokes are written gfs2: drain the ail2 list after io errors gfs2: Withdraw in gfs2_ail1_flush if write_cache_pages fails gfs2: Do log_flush in gfs2_ail_empty_gl even if ail list is empty ...

Pull x86 timer updates from Thomas Gleixner: "A series of commits to make the MSR derived CPU and TSC frequency more accurate. It turned out that the frequency tables which have been taken from the SDM are inaccurate because the SDM provides truncated and rounded values, e.g. 83.3Mhz (83.3333...) or 116.7Mhz (116.6666...). This causes time drift in the range of ~1 second per hour (20-30 seconds per day). On some of these SoCs it's not possible to recalibrate the TSC because there is no reference (PIT, HPET) available. With some reverse engineering it was established that the possible frequencies are derived from the base clock with fixed multiplier / divider pairs. For the CPU models which have a known crystal frequency the kernel now uses multiplier / divider pairs which bring the frequencies closer to reality and fix the observed time drift issues" * tag 'x86-timers-2020-03-30' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86/tsc_msr: Make MSR derived TSC frequency more accurate x86/tsc_msr: Fix MSR_FSB_FREQ mask for Cherry Trail devices x86/tsc_msr: Use named struct initializers

Pull x86 splitlock updates from Thomas Gleixner: "Support for 'split lock' detection: Atomic operations (lock prefixed instructions) which span two cache lines have to acquire the global bus lock. This is at least 1k cycles slower than an atomic operation within a cache line and disrupts performance on other cores. Aside of performance disruption this is a unpriviledged form of DoS. Some newer CPUs have the capability to raise an #AC trap when such an operation is attempted. The detection is by default enabled in warning mode which will warn once when a user space application is caught. A command line option allows to disable the detection or to select fatal mode which will terminate offending applications with SIGBUS" * tag 'x86-splitlock-2020-03-30' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86/split_lock: Avoid runtime reads of the TEST_CTRL MSR x86/split_lock: Rework the initialization flow of split lock detection x86/split_lock: Enable split lock detection by kernel

There's a semantic conflict in the Octeon staging network driver, which used the skb_reset_tc() function to reset skb state when re-using an skb. But that inline helper function was removed in mainline by commit 2c64605b ("net: Fix CONFIG_NET_CLS_ACT=n and CONFIG_NFT_FWD_NETDEV={y, m} build"). Fix it by using skb_reset_redirect() instead. Also move it out of the This code path only ends up triggering if REUSE_SKBUFFS_WITHOUT_FREE is enabled, which in turn only happens if you don't have CONFIG_NETFILTER configured. Which was how this wasn't caught by the usual allmodconfig builds.

Pull scheduler updates from Ingo Molnar: "The main changes in this cycle are: - Various NUMA scheduling updates: harmonize the load-balancer and NUMA placement logic to not work against each other. The intended result is better locality, better utilization and fewer migrations. - Introduce Thermal Pressure tracking and optimizations, to improve task placement on thermally overloaded systems. - Implement frequency invariant scheduler accounting on (some) x86 CPUs. This is done by observing and sampling the 'recent' CPU frequency average at ~tick boundaries. The CPU provides this data via the APERF/MPERF MSRs. This hopefully makes our capacity estimates more precise and keeps tasks on the same CPU better even if it might seem overloaded at a lower momentary frequency. (As usual, turbo mode is a complication that we resolve by observing the maximum frequency and renormalizing to it.) - Add asymmetric CPU capacity wakeup scan to improve capacity utilization on asymmetric topologies.

When using NFSv4.2, the security label for the root inode should be set via a call to nfs_setsecurity() during the mount process, otherwise the inode will appear as unlabeled for up to acdirmin seconds. Currently the label for the root inode is allocated, retrieved, and freed entirely witin nfs4_proc_get_root(). Add a field for the label to the nfs_fattr struct, and allocate & free the label in nfs_get_root(), where we also add a call to nfs_setsecurity(). Note that for the call to nfs_setsecurity() to succeed, it's necessary to also move the logic calling security_sb_{set,clone}_security() from nfs_get_tree_common() down into nfs_get_root()... otherwise the SBLABEL_MNT flag will not be set in the super_block's security flags and nfs_setsecurity() will silently fail.
