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

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.

git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull EFI updates from Ingo Molnar: "The EFI changes in this cycle are much larger than usual, for two (positive) reasons: - The GRUB project is showing signs of life again, resulting in the introduction of the generic Linux/UEFI boot protocol, instead of x86 specific hacks which are increasingly difficult to maintain. There's hope that all future extensions will now go through that boot protocol. - Preparatory work for RISC-V EFI support. The main changes are: - Boot time GDT handling changes - Simplify handling of EFI properties table on arm64 - Generic EFI stub cleanups, to improve command line handling, file I/O, memory allocation, etc. - Introduce a generic initrd loading method based on calling back into the firmware, instead of relying on the x86 EFI handover protocol or device tree. - Introduce a mixed mode boot method that does not rely on the x86 EFI handover protocol either, and could potentially be adopted by other architectures (if another one ever surfaces where one execution mode is a superset of another) - Clean up the contents of 'struct efi', and move out everything that doesn't need to be stored there. - Incorporate support for UEFI spec v2.8A changes that permit firmware implementations to return EFI_UNSUPPORTED from UEFI runtime services at OS runtime, and expose a mask of which ones are supported or unsupported via a configuration table. - Partial fix for the lack of by-VA cache maintenance in the decompressor on 32-bit ARM. - Changes to load device firmware from EFI boot service memory regions - Various documentation updates and minor code cleanups and fixes" * 'efi-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (114 commits) efi/libstub/arm: Fix spurious message that an initrd was loaded efi/libstub/arm64: Avoid image_base value from efi_loaded_image partitions/efi: Fix partition name parsing in GUID partition entry efi/x86: Fix cast of image argument efi/libstub/x86: Use ULONG_MAX as upper bound for all allocations efi: Fix a mistype in comments mentioning efivar_entry_iter_begin() efi/libstub: Avoid linking libstub/lib-ksyms.o into vmlinux efi/x86: Preserve %ebx correctly in efi_set_virtual_address_map() efi/x86: Ignore the memory attributes table on i386 efi/x86: Don't relocate the kernel unless necessary efi/x86: Remove extra headroom for setup block efi/x86: Add kernel preferred address to PE header efi/x86: Decompress at start of PE image load address x86/boot/compressed/32: Save the output address instead of recalculating it efi/libstub/x86: Deal with exit() boot service returning x86/boot: Use unsigned comparison for addresses efi/x86: Avoid using code32_start efi/x86: Make efi32_pe_entry() more readable efi/x86: Respect 32-bit ABI in efi32_pe_entry() efi/x86: Annotate the LOADED_IMAGE_PROTOCOL_GUID with SYM_DATA ...

2020-03-29ethtool: provide timestamping information with TSINFO_GET requestMichal Kubecek1-1/+29
Implement TSINFO_GET request to get timestamping information for a network device. This is traditionally available via ETHTOOL_GET_TS_INFO ioctl request. Move part of ethtool_get_ts_info() into common.c so that ioctl and netlink code use the same logic to get timestamping information from the device. v3: use "TSINFO" rather than "TIMESTAMP", suggested by Richard Cochran Signed-off-by: Michal Kubecek <mkubecek@suse.cz> Acked-by: Richard Cochran <richardcochran@gmail.com> Signed-off-by: David S.

2020-03-29ethtool: set EEE settings with EEE_SET requestMichal Kubecek1-1/+24
Implement EEE_SET netlink request to set EEE settings of a network device. These are traditionally set with ETHTOOL_SEEE ioctl request. The netlink interface allows setting the EEE status for all link modes supported by kernel but only first 32 link modes can be set at the moment as only those are supported by the ethtool_ops callback.

Implement EEE_GET request to get EEE settings of a network device. These are traditionally available via ETHTOOL_GEEE ioctl request. The netlink interface allows reporting EEE status for all link modes supported by kernel but only first 32 link modes are provided at the moment as only those are reported by the ethtool_ops callback and drivers. v2: fix alignment (whitespace only) Signed-off-by: Michal Kubecek <mkubecek@suse.cz> Signed-off-by: David S.

Implement COALESCE_SET netlink request to set coalescing parameters of a network device. These are traditionally set with ETHTOOL_SCOALESCE ioctl request. This commit adds only support for device coalescing parameters, not per queue coalescing parameters. Like the ioctl implementation, the generic ethtool code checks if only supported parameters are modified; if not, first offending attribute is reported using extack. v2: fix alignment (whitespace only) Signed-off-by: Michal Kubecek <mkubecek@suse.cz> Reviewed-by: Jakub Kicinski <kuba@kernel.org> Signed-off-by: David S.

This commit adds only support for device coalescing parameters, not per queue coalescing parameters.
