When connecting the Trackpad 1 via any bluetooth adapter, the device disconnects whenever the battery level is queried. It reconnects again after a few seconds, but it's an incredibly jarring experience since it will just cut out in the middle of mouse operations. This patch ignores querying the battery and avoids disconnects. This bug is reported here: - https://bugzilla.kernel.org/show_bug.cgi?id=204589 - https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1834085 It looks like a similar approach (disabling battery checking) was also suggested for the Apple Magic Mouse before a custom driver was created: https://bugzilla.kernel.org/show_bug.cgi?id=103631Signed-off-by: Nimish Gåtam <nimishg@gmail.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz>

Commit 9f4211bf ("HID: add mapping for camera access keys") added mapping for the camera access keys, but unfortunately used wrong usage codes for them. HUTRR72[1] specifies that camera access controls use 0x76, 0x077 and 0x78 usages in the consumer control page. Previously mapped 0xd5, 0xd6 and 0xd7 usages are actually defined in HUTRR64[2] as game recording controls.

Match alignment information in composite type declarations used by packed HOSTCMD report structures. Compiler packing attribute is not recursive for inner declarations. Mismatched alignment information can cause undefined behavior in code generated for accessing composite type members. struct pointers passed to thunderstrike_parse_board_info_payload and thunderstrike_parse_haptics_payload are an example of this being potentially problematic since alignment information from the packed HOSTCMD report is lost.

Pull clk updates from Stephen Boyd: "This batch of clk driver updates contains almost no new SoC support. Instead there's a treewide patch series from Maxime that makes clk_ops::determine_rate mandatory for muxes. Beyond that core framework change we have the usual pile of clk driver updates such as migrating i2c drivers to use .probe() again or YAMLfication of clk DT bindings so we can validate DTBs. Overall the SoCs that got the most updates this time around in terms of diffstat are the Amlogic and Mediatek drivers because they added new SoC support or fixed up various drivers to have proper data. In general things look kinda quiet. I suspect the core framework change may still shake out some problems after the merge window, mostly because not everyone tests linux-next where that series has been for some number of weeks. I saw that there's at least one pending fix for Tegra that needs to be wrapped up into a proper patch. I'll try to catch those bits before the window closes so that -rc1 is bootable. More details below.

There is no xas_pause(&xas) in collapse_file()'s main loop, at the points where it does xas_unlock_irq(&xas) and then continues. That would explain why, once two weeks ago and twice yesterday, I have hit the VM_BUG_ON_PAGE(page != xas_load(&xas), page) since "mm/khugepaged: fix iteration in collapse_file" removed the xas_set(&xas, index) just before it: xas.xa_node could be left pointing to a stale node, if there was concurrent activity on the file which transformed its xarray. I tried inserting xas_pause()s, but then even bootup crashed on that VM_BUG_ON_PAGE(): there appears to be a subtle "nextness" implicit in xas_pause(). xas_next() and xas_pause() are good for use in simple loops, but not in this one: xas_set() worked well until now, so use xas_set(&xas, index) explicitly at the head of the loop; and change that VM_BUG_ON_PAGE() not to need its own xas_set(), and not to interfere with the xa_state (which would probably stop the crashes from xas_pause(), but I trust that less). The user-visible effects of this bug (if VM_BUG_ONs are configured out) would be data loss and data leak - potentially - though in practice I expect it is more likely that a subsequent check (e.g. on mapping or on nr_none) would notice an inconsistency, and just abandon the collapse.

This modifies our user mode stack expansion code to always take the mmap_lock for writing before modifying the VM layout. It's actually something we always technically should have done, but because we didn't strictly need it, we were being lazy ("opportunistic" sounds so much better, doesn't it?) about things, and had this hack in place where we would extend the stack vma in-place without doing the proper locking. And it worked fine. We just needed to change vm_start (or, in the case of grow-up stacks, vm_end) and together with some special ad-hoc locking using the anon_vma lock and the mm->page_table_lock, it all was fairly straightforward. That is, it was all fine until Ruihan Li pointed out that now that the vma layout uses the maple tree code, we *really* don't just change vm_start and vm_end any more, and the locking really is broken. Oops. It's not actually all _that_ horrible to fix this once and for all, and do proper locking, but it's a bit painful. We have basically three different cases of stack expansion, and they all work just a bit differently: - the common and obvious case is the page fault handling. It's actually fairly simple and straightforward, except for the fact that we have something like 24 different versions of it, and you end up in a maze of twisty little passages, all alike. - the simplest case is the execve() code that creates a new stack. There are no real locking concerns because it's all in a private new VM that hasn't been exposed to anybody, but lockdep still can end up unhappy if you get it wrong. - and finally, we have GUP and page pinning, which shouldn't really be expanding the stack in the first place, but in addition to execve() we also use it for ptrace(). And debuggers do want to possibly access memory under the stack pointer and thus need to be able to expand the stack as a special case. None of these cases are exactly complicated, but the page fault case in particular is just repeated slightly differently many many times. And ia64 in particular has a fairly complicated situation where you can have both a regular grow-down stack _and_ a special grow-up stack for the register backing store. So to make this slightly more manageable, the bulk of this series is to first create a helper function for the most common page fault case, and convert all the straightforward architectures to it. Thus the new 'lock_mm_and_find_vma()' helper function, which ends up being used by x86, arm, powerpc, mips, riscv, alpha, arc, csky, hexagon, loongarch, nios2, sh, sparc32, and xtensa. So we not only convert more than half the architectures, we now have more shared code and avoid some of those twisty little passages. And largely due to this common helper function, the full diffstat of this series ends up deleting more lines than it adds. That still leaves eight architectures (ia64, m68k, microblaze, openrisc, parisc, s390, sparc64 and um) that end up doing 'expand_stack()' manually because they are doing something slightly different from the normal pattern. Along with the couple of special cases in execve() and GUP. So there's a couple of patches that first create 'locked' helper versions of the stack expansion functions, so that there's a obvious path forward in the conversion. The execve() case is then actually pretty simple, and is a nice cleanup from our old "grow-up stackls are special, because at execve time even they grow down". The #ifdef CONFIG_STACK_GROWSUP in that code just goes away, because it's just more straightforward to write out the stack expansion there manually, instead od having get_user_pages_remote() do it for us in some situations but not others and have to worry about locking rules for GUP. And the final step is then to just convert the remaining odd cases to a new world order where 'expand_stack()' is called with the mmap_lock held for reading, but where it might drop it and upgrade it to a write, only to return with it held for reading (in the success case) or with it completely dropped (in the failure case). In the process, we remove all the stack expansion from GUP (where dropping the lock wouldn't be ok without special rules anyway), and add it in manually to __access_remote_vm() for ptrace(). Thanks to Adrian Glaubitz and Frank Scheiner who tested the ia64 cases. Everything else here felt pretty straightforward, but the ia64 rules for stack expansion are really quite odd and very different from everything else. Also thanks to Vegard Nossum who caught me getting one of those odd conditions entirely the wrong way around. Anyway, I think I want to actually move all the stack expansion code to a whole new file of its own, rather than have it split up between mm/mmap.c and mm/memory.c, but since this will have to be backported to the initial maple tree vma introduction anyway, I tried to keep the patches _fairly_ minimal. Also, while I don't think it's valid to expand the stack from GUP, the final patch in here is a "warn if some crazy GUP user wants to try to expand the stack" patch. That one will be reverted before the final release, but it's left to catch any odd cases during the merge window and release candidates.

Pull networking changes from Jakub Kicinski: "WiFi 7 and sendpage changes are the biggest pieces of work for this release. The latter will definitely require fixes but I think that we got it to a reasonable point. Core: - Rework the sendpage & splice implementations Instead of feeding data into sockets page by page extend sendmsg handlers to support taking a reference on the data, controlled by a new flag called MSG_SPLICE_PAGES Rework the handling of unexpected-end-of-file to invoke an additional callback instead of trying to predict what the right combination of MORE/NOTLAST flags is Remove the MSG_SENDPAGE_NOTLAST flag completely - Implement SCM_PIDFD, a new type of CMSG type analogous to SCM_CREDENTIALS, but it contains pidfd instead of plain pid - Enable socket busy polling with CONFIG_RT - Improve reliability and efficiency of reporting for ref_tracker - Auto-generate a user space C library for various Netlink families Protocols: - Allow TCP to shrink the advertised window when necessary, prevent sk_rcvbuf auto-tuning from growing the window all the way up to tcp_rmem[2] - Use per-VMA locking for "page-flipping" TCP receive zerocopy - Prepare TCP for device-to-device data transfers, by making sure that payloads are always attached to skbs as page frags - Make the backoff time for the first N TCP SYN retransmissions linear. Exponential backoff is unnecessarily conservative - Create a new MPTCP getsockopt to retrieve all info (MPTCP_FULL_INFO) - Avoid waking up applications using TLS sockets until we have a full record - Allow using kernel memory for protocol ioctl callbacks, paving the way to issuing ioctls over io_uring - Add nolocalbypass option to VxLAN, forcing packets to be fully encapsulated even if they are destined for a local IP address - Make TCPv4 use consistent hash in TIME_WAIT and SYN_RECV. Ensure in-kernel ECMP implementation (e.g. Open vSwitch) select the same link for all packets. Support L4 symmetric hashing in Open vSwitch - PPPoE: make number of hash bits configurable - Allow DNS to be overwritten by DHCPACK in the in-kernel DHCP client (ipconfig) - Add layer 2 miss indication and filtering, allowing higher layers (e.g. ACL filters) to make forwarding decisions based on whether packet matched forwarding state in lower devices (bridge) - Support matching on Connectivity Fault Management (CFM) packets - Hide the "link becomes ready" IPv6 messages by demoting their printk level to debug - HSR: don't enable promiscuous mode if device offloads the proto - Support active scanning in IEEE 802.15.4 - Continue work on Multi-Link Operation for WiFi 7 BPF: - Add precision propagation for subprogs and callbacks. This allows maintaining verification efficiency when subprograms are used, or in fact passing the verifier at all for complex programs, especially those using open-coded iterators - Improve BPF's {g,s}setsockopt() length handling. Previously BPF assumed the length is always equal to the amount of written data. But some protos allow passing a NULL buffer to discover what the output buffer *should* be, without writing anything - Accept dynptr memory as memory arguments passed to helpers - Add routing table ID to bpf_fib_lookup BPF helper - Support O_PATH FDs in BPF_OBJ_PIN and BPF_OBJ_GET commands - Drop bpf_capable() check in BPF_MAP_FREEZE command (used to mark maps as read-only) - Show target_{obj,btf}_id in tracing link fdinfo - Addition of several new kfuncs (most of the names are self-explanatory): - Add a set of new dynptr kfuncs: bpf_dynptr_adjust(), bpf_dynptr_is_null(), bpf_dynptr_is_rdonly(), bpf_dynptr_size() and bpf_dynptr_clone(). - bpf_task_under_cgroup() - bpf_sock_destroy() - force closing sockets - bpf_cpumask_first_and(), rework bpf_cpumask_any*() kfuncs Netfilter: - Relax set/map validation checks in nf_tables. Allow checking presence of an entry in a map without using the value - Increase ip_vs_conn_tab_bits range for 64BIT builds - Allow updating size of a set - Improve NAT tuple selection when connection is closing Driver API: - Integrate netdev with LED subsystem, to allow configuring HW "offloaded" blinking of LEDs based on link state and activity (i.e. packets coming in and out) - Support configuring rate selection pins of SFP modules - Factor Clause 73 auto-negotiation code out of the drivers, provide common helper routines - Add more fool-proof helpers for managing lifetime of MDIO devices associated with the PCS layer - Allow drivers to report advanced statistics related to Time Aware scheduler offload (taprio) - Allow opting out of VF statistics in link dump, to allow more VFs to fit into the message - Split devlink instance and devlink port operations New hardware / drivers: - Ethernet: - Synopsys EMAC4 IP support (stmmac) - Marvell 88E6361 8 port (5x1GE + 3x2.5GE) switches - Marvell 88E6250 7 port switches - Microchip LAN8650/1 Rev.B0 PHYs - MediaTek MT7981/MT7988 built-in 1GE PHY driver - WiFi: - Realtek RTL8192FU, 2.4 GHz, b/g/n mode, 2T2R, 300 Mbps - Realtek RTL8723DS (SDIO variant) - Realtek RTL8851BE - CAN: - Fintek F81604 Drivers: - Ethernet NICs: - Intel (100G, ice): - support dynamic interrupt allocation - use meta data match instead of VF MAC addr on slow-path - nVidia/Mellanox: - extend link aggregation to handle 4, rather than just 2 ports - spawn sub-functions without any features by default - OcteonTX2: - support HTB (Tx scheduling/QoS) offload - make RSS hash generation configurable - support selecting Rx queue using TC filters - Wangxun (ngbe/txgbe): - add basic Tx/Rx packet offloads - add phylink support (SFP/PCS control) - Freescale/NXP (enetc): - report TAPRIO packet statistics - Solarflare/AMD: - support matching on IP ToS and UDP source port of outer header - VxLAN and GENEVE tunnel encapsulation over IPv4 or IPv6 - add devlink dev info support for EF10 - Virtual NICs: - Microsoft vNIC: - size the Rx indirection table based on requested configuration - support VLAN tagging - Amazon vNIC: - try to reuse Rx buffers if not fully consumed, useful for ARM servers running with 16kB pages - Google vNIC: - support TCP segmentation of >64kB frames - Ethernet embedded switches: - Marvell (mv88e6xxx): - enable USXGMII (88E6191X) - Microchip: - lan966x: add support for Egress Stage 0 ACL engine - lan966x: support mapping packet priority to internal switch priority (based on PCP or DSCP) - Ethernet PHYs: - Broadcom PHYs: - support for Wake-on-LAN for BCM54210E/B50212E - report LPI counter - Microsemi PHYs: support RGMII delay configuration (VSC85xx) - Micrel PHYs: receive timestamp in the frame (LAN8841) - Realtek PHYs: support optional external PHY clock - Altera TSE PCS: merge the driver into Lynx PCS which it is a variant of - CAN: Kvaser PCIEcan: - support packet timestamping - WiFi: - Intel (iwlwifi): - major update for new firmware and Multi-Link Operation (MLO) - configuration rework to drop test devices and split the different families - support for segmented PNVM images and power tables - new vendor entries for PPAG (platform antenna gain) feature - Qualcomm 802.11ax (ath11k): - Multiple Basic Service Set Identifier (MBSSID) and Enhanced MBSSID Advertisement (EMA) support in AP mode - support factory test mode - RealTek (rtw89): - add RSSI based antenna diversity - support U-NII-4 channels on 5 GHz band - RealTek (rtl8xxxu): - AP mode support for 8188f - support USB RX aggregation for the newer chips" * tag 'net-next-6.5' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next: (1602 commits) net: scm: introduce and use scm_recv_unix helper af_unix: Skip SCM_PIDFD if scm->pid is NULL. net: lan743x: Simplify comparison netlink: Add __sock_i_ino() for __netlink_diag_dump(). net: dsa: avoid suspicious RCU usage for synced VLAN-aware MAC addresses Revert "af_unix: Call scm_recv() only after scm_set_cred()." phylink: ReST-ify the phylink_pcs_neg_mode() kdoc libceph: Partially revert changes to support MSG_SPLICE_PAGES net: phy: mscc: fix packet loss due to RGMII delays net: mana: use vmalloc_array and vcalloc net: enetc: use vmalloc_array and vcalloc ionic: use vmalloc_array and vcalloc pds_core: use vmalloc_array and vcalloc gve: use vmalloc_array and vcalloc octeon_ep: use vmalloc_array and vcalloc net: usb: qmi_wwan: add u-blox 0x1312 composition perf trace: fix MSG_SPLICE_PAGES build error ipvlan: Fix return value of ipvlan_queue_xmit() netfilter: nf_tables: fix underflow in chain reference counter netfilter: nf_tables: unbind non-anonymous set if rule construction fails ...

Pull sysctl updates from Luis Chamberlain: "The changes for sysctl are in line with prior efforts to stop usage of deprecated routines which incur recursion and also make it hard to remove the empty array element in each sysctl array declaration. The most difficult user to modify was parport which required a bit of re-thinking of how to declare shared sysctls there, Joel Granados has stepped up to the plate to do most of this work and eventual removal of register_sysctl_table(). That work ended up saving us about 1465 bytes according to bloat-o-meter. Since we gained a few bloat-o-meter karma points I moved two rather small sysctl arrays from kernel/sysctl.c leaving us only two more sysctl arrays to move left. Most changes have been tested on linux-next for about a month. The last straggler patches are a minor parport fix, changes to the sysctl kernel selftest so to verify correctness and prevent regressions for the future change he made to provide an alternative solution for the special sysctl mount point target which was using the now deprecated sysctl child element. This is all prep work to now finally be able to remove the empty array element in all sysctl declarations / registrations which is expected to save us a bit of bytes all over the kernel.

This is the new-and-improved attempt at avoiding huge memory load spikes when the user space boot sequence tries to load hundreds (or even thousands) of redundant duplicate modules in parallel. See commit 9828ed3f ("module: error out early on concurrent load of the same module file") for background and an earlier failed attempt that was reverted. That earlier attempt just said "concurrently loading the same module is silly, just open the module file exclusively and return -ETXTBSY if somebody else is already loading it". While it is true that concurrent module loads of the same module is silly, the reason that earlier attempt then failed was that the concurrently loaded module would often be a prerequisite for another module. Thus failing to load the prerequisite would then cause cascading failures of the other modules, rather than just short-circuiting that one unnecessary module load. At the same time, we still really don't want to load the contents of the same module file hundreds of times, only to then wait for an eventually successful load, and have everybody else return -EEXIST. As a result, this takes another approach, and treats concurrent module loads from the same file as "idempotent" in the inode. So if one module load is ongoing, we don't start a new one, but instead just wait for the first one to complete and return the same return value as it did. So unlike the first attempt, this does not return early: the intent is not to speed up the boot, but to avoid a thundering herd problem in allocating memory (both physical and virtual) for a module more than once. Also note that this does change behavior: it used to be that when you had concurrent loads, you'd have one "winner" that would return success, and everybody else would return -EEXIST. In contrast, this idempotent logic goes all Oprah on the problem, and says "You are a winner! And you are a winner! We are ALL winners". But since there's no possible actual real semantic difference between "you loaded the module" and "somebody else already loaded the module", this is more of a feel-good change than an actual honest-to-goodness semantic change. Of course, any true Johnny-come-latelies that don't get caught in the concurrency filter will still return -EEXIST. It's no different from not even getting a seat at an Oprah taping. That's life. See the long thread on the kernel mailing list about this all, which includes some numbers for memory use before and after the patch.

This means that even with the new features for the maple tree cache we'd have a nice negative diffstat were it not for the addition of a bunch more KUnit coverage.

The memory encryption initialization logic was moved from init/main.c into arch_cpu_finalize_init() in commit 439e1757 ("init, x86: Move mem_encrypt_init() into arch_cpu_finalize_init()"), but a stale declaration for the init function was left in <linux/init.h>. And didn't cause any problems if you had X86_MEM_ENCRYPT enabled, which apparently everybody involved did have.

Commit ca5e8632 ("mm/gup: remove vmas parameter from get_user_pages_remote()") removed the vma argument from GUP handling, and instead added a helper function (get_user_page_vma_remote()) that looks it up separately using 'vma_lookup()'. And then converted existing users that needed a vma to use the helper instead. However, the helper function intentionally acts exactly like the old get_user_pages_remote() did, and only fills in 'vma' on successful page lookup. Fine so far. However, __access_remote_vm() wants the vma even for the unsuccessful case, and used to do a vma = vma_lookup(mm, addr); explicitly to look it up when the get_user_page() failed. However, that conversion commit incorrectly removed that vma lookup, thinking that get_user_page_vma_remote() would have done it. Not so. So add the vma_lookup() back in.

Pull hardening updates from Kees Cook: "There are three areas of note: A bunch of strlcpy()->strscpy() conversions ended up living in my tree since they were either Acked by maintainers for me to carry, or got ignored for multiple weeks (and were trivial changes). The compiler option '-fstrict-flex-arrays=3' has been enabled globally, and has been in -next for the entire devel cycle. This changes compiler diagnostics (though mainly just -Warray-bounds which is disabled) and potential UBSAN_BOUNDS and FORTIFY _warning_ coverage. In other words, there are no new restrictions, just potentially new warnings. Any new FORTIFY warnings we've seen have been fixed (usually in their respective subsystem trees). For more details, see commit df8fc4e9. The under-development compiler attribute __counted_by has been added so that we can start annotating flexible array members with their associated structure member that tracks the count of flexible array elements at run-time. It is possible (likely?) that the exact syntax of the attribute will change before it is finalized, but GCC and Clang are working together to sort it out. Any changes can be made to the macro while we continue to add annotations. As an example of that last case, I have a treewide commit waiting with such annotations found via Coccinelle: https://git.kernel.org/linus/adc5b3cb48a049563dc673f348eab7b6beba8a9b Also see commit dd06e72e for more details. Summary: - Fix KMSAN vs FORTIFY in strlcpy/strlcat (Alexander Potapenko) - Convert strreplace() to return string start (Andy Shevchenko) - Flexible array conversions (Arnd Bergmann, Wyes Karny, Kees Cook) - Add missing function prototypes seen with W=1 (Arnd Bergmann) - Fix strscpy() kerndoc typo (Arne Welzel) - Replace strlcpy() with strscpy() across many subsystems which were either Acked by respective maintainers or were trivial changes that went ignored for multiple weeks (Azeem Shaikh) - Remove unneeded cc-option test for UBSAN_TRAP (Nick Desaulniers) - Add KUnit tests for strcat()-family - Enable KUnit tests of FORTIFY wrappers under UML - Add more complete FORTIFY protections for strlcat() - Add missed disabling of FORTIFY for all arch purgatories. - Enable -fstrict-flex-arrays=3 globally - Tightening UBSAN_BOUNDS when using GCC - Improve checkpatch to check for strcpy, strncpy, and fake flex arrays - Improve use of const variables in FORTIFY - Add requested struct_size_t() helper for types not pointers - Add __counted_by macro for annotating flexible array size members" * tag 'hardening-v6.5-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux: (54 commits) netfilter: ipset: Replace strlcpy with strscpy uml: Replace strlcpy with strscpy um: Use HOST_DIR for mrproper kallsyms: Replace all non-returning strlcpy with strscpy sh: Replace all non-returning strlcpy with strscpy of/flattree: Replace all non-returning strlcpy with strscpy sparc64: Replace all non-returning strlcpy with strscpy Hexagon: Replace all non-returning strlcpy with strscpy kobject: Use return value of strreplace() lib/string_helpers: Change returned value of the strreplace() jbd2: Avoid printing outside the boundary of the buffer checkpatch: Check for 0-length and 1-element arrays riscv/purgatory: Do not use fortified string functions s390/purgatory: Do not use fortified string functions x86/purgatory: Do not use fortified string functions acpi: Replace struct acpi_table_slit 1-element array with flex-array clocksource: Replace all non-returning strlcpy with strscpy string: use __builtin_memcpy() in strlcpy/strlcat staging: most: Replace all non-returning strlcpy with strscpy drm/i2c: tda998x: Replace all non-returning strlcpy with strscpy ...

Pull lsm updates from Paul Moore: - A SafeSetID patch to correct what appears to be a cut-n-paste typo in the code causing a UID to be printed where a GID was desired. This is coming via the LSM tree because we haven't been able to get a response from the SafeSetID maintainer (Micah Morton) in several months. Hopefully we are able to get in touch with Micah, but until we do I'm going to pick them up in the LSM tree. - A small fix to the reiserfs LSM xattr code. We're continuing to work through some issues with the reiserfs code as we try to fixup the LSM xattr handling, but in the process we're uncovering some ugly problems in reiserfs and we may just end up removing the LSM xattr support in reiserfs prior to reiserfs' removal. For better or worse, this shouldn't impact any of the reiserfs users, as we discovered that LSM xattrs on reiserfs were completely broken, meaning no one is currently using the combo of reiserfs and a file labeling LSM. - A tweak to how the cap_user_data_t struct/typedef is declared in the header file to appease the Sparse gods. - In the process of trying to sort out the SafeSetID lost-maintainer problem I realized that I needed to update the labeled networking entry to "Supported". - Minor comment/documentation and spelling fixes. * tag 'lsm-pr-20230626' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/lsm: device_cgroup: Fix kernel-doc warnings in device_cgroup SafeSetID: fix UID printed instead of GID MAINTAINERS: move labeled networking to "supported" capability: erase checker warnings about struct __user_cap_data_struct lsm: fix a number of misspellings reiserfs: Initialize sec->length in reiserfs_security_init(). capability: fix kernel-doc warnings in capability.c

Pull selinux updates from Paul Moore: - Thanks to help from the MPTCP folks, it looks like we have finally sorted out a proper solution to the MPTCP socket labeling issue, see the new security_mptcp_add_subflow() LSM hook. - Fix the labeled NFS handling such that a labeled NFS share mounted prior to the initial SELinux policy load is properly labeled once a policy is loaded; more information in the commit description. - Two patches to security/selinux/Makefile, the first took the cleanups in v6.4 a bit further and the second removed the grouped targets support as that functionality doesn't appear to be properly supported prior to make v4.3. - Deprecate the "fs" object context type in SELinux policies. The fs object context type was an old vestige that was introduced back in v2.6.12-rc2 but never really used. - A number of small changes that remove dead code, clean up some awkward bits, and generally improve the quality of the code.
