Summary: Linux 4.4 has not been released
1. Prominent features
2. Drivers and architectures
All the driver and architecture-specific changes can be found in the [http://kernelnewbies.org/Linux_4.4-DriversArch Linux_4.4-DriversArch] page
3. Core (various)
Add support for sync O_DIRECT read/write poll support [https://git.kernel.org/torvalds/c/15c4f638f3d41bae52105ca4c0c8760afbcbeaab commit]
watchdog: Mimic the softlockup_panic kernel knob and create a /proc/sys/kernel/hardlockup_panic. It enables a hardlockup to panic the machine [https://git.kernel.org/torvalds/c/ac1f591249d95372f3a5ab3828d4af5dfbf5efd3 commit]
watchdog: optionally perform all-CPU backtrace in case of hard lockup. Can be enabled with sysctl /proc/sys/kernel/hardlockup_all_cpu_backtrace [https://git.kernel.org/torvalds/c/55537871ef666b4153fd1ef8782e4a13fee142cc commit]
coredump: Add two new flags to the existing coredump mechanism for ELF and FDPIC ELF files to allow us to explicitly filter DAX mappings. This is desirable because DAX mappings, like hugetlb mappings, have the potential to be very large [https://git.kernel.org/torvalds/c/5037835c1f3eabf4f22163fc0278dd87165f8957 commit], [https://git.kernel.org/torvalds/c/ab27a8d04b32b6ee8c30c14c4afd1058e8addc82 commit]
4. File systems
- XFS
Add per-filesystem stats in /sys/fs/xfs/<block>/stats/stats, and a stats_clear file to clear them. Also, the global stats that are currently present in /proc are duplicated in /sys/fs/xfs/stats/stats (along with a stats_clear file) [https://git.kernel.org/torvalds/c/bb230c124730f21eea13deab433f9f8fc96bd5f3 commit], [https://git.kernel.org/torvalds/c/225e4635580ce9fb12f8a2dc88473161cd64dbf6 commit], [https://git.kernel.org/torvalds/c/ff6d6af2351caea7db681f4539d0d893e400557a commit]
- BTRFS
Add fragment debug mount option. It can be used to cause extreme fragmentation in data, metadata or both [https://git.kernel.org/torvalds/c/d0bd456074dca089579818312da7cbe726ad2ff9 commit]
Add balance filter for stripes. This is useful to selectively rebalance only chunks that do not span enough devices, applies to RAID0/10/5/6. [https://git.kernel.org/torvalds/c/dee32d0ac3719ef8d640efaf0884111df444730f commit]
- CIFS
Allow duplicate extents (cp --reflink) in SMB3.0 not just SMB3.1.1 [https://git.kernel.org/torvalds/c/ca9e7a1c85594f61d7ffb414071e6cae82eae23a commit]
Add resilienthandles mount parameter. Since many servers (Windows clients, and non-clustered servers) do not support persistent handles but do support resilient handles, allow the user to specify a mount option "resilienthandles" in order to get more reliable connections and less chance of data loss (at least when SMB2.1 or later). Default resilient handle timeout (120 seconds to recent Windows server) is used [https://git.kernel.org/torvalds/c/592fafe644bf3a48b9e00e182a67d301493634fc commit]
Add support for persistent handles, which are like durable file handles with strong guarantees [https://git.kernel.org/torvalds/c/b2a3077414fd6ff1de8972ea55e91f27bcabd913 commit], [https://git.kernel.org/torvalds/c/f16dfa7cd1b588e5d7ef4b5a19ee579f11b7a41f commit], [https://git.kernel.org/torvalds/c/b618f001a20e44f691dd0e2ffea651a40a651871 commit]
Allow copy offload (copychunk) across shares [https://git.kernel.org/torvalds/c/7b52e2793a58af61b5d349c2c080437a437a4edb commit]
- NFS
Support for NFSv4.2 file CLONE using the btrfs ioctl [https://git.kernel.org/torvalds/c/21fad313d5890b674432fe3ad0c7bcf040320340 commit] [https://git.kernel.org/torvalds/c/e5341f3a5762d17be9cdd06257c02c0098bdcab8 commit], [https://git.kernel.org/torvalds/c/36022770de6cf9a403c40a68712ed2d2ea2746be commit], [https://git.kernel.org/torvalds/c/bea51b30b281039f0f43fb4f42028ddf33fb601f commit], [https://git.kernel.org/torvalds/c/a340abcf4173461f688292a6879b4d5bc781c2b1 commit]
- EXT4
Store checksum seed in superblock [https://git.kernel.org/torvalds/c/8c81bd8f586c46eaf114758a78d82895a2b081c2 commit]
- OCFS2
Improve performance for localalloc [https://git.kernel.org/torvalds/c/1d1aff8cf367d2216a678c722161784e207965c4 commit]
5. Memory management
Get rid of vmalloc_info from /proc/meminfo. It is too expensive to calculate and shows up in real workloads, people who actually want to know what the situation is wrt the vmalloc area should just look at the much more complete /proc/vmallocinfo instead [https://git.kernel.org/torvalds/c/a5ad88ce8c7fae7ddc72ee49a11a75aa837788e0 commit]
Add HugetlbPages field to /proc/PID/status. Currently there's no easy way to get per-process usage of hugetlb pages, which is inconvenient because userspace applications which use hugetlb can need it [https://git.kernel.org/torvalds/c/5d317b2b6536592a9b51fe65faed43d65ca9158e commit]
Add hugetlb-related fields to /proc/PID/smaps to know per-task or per-vma base hugetlb usage: AnonHugePages shows the amount of memory backed by transparent hugepage; Shared_Hugetlb and Private_Hugetlb show the amounts of memory backed by hugetlbfs page which is not counted in RSS or PSS field for historical reasons. And these are not included in {Shared,Private}_{Clean,Dirty} field [https://git.kernel.org/torvalds/c/25ee01a2fca02dfb5a3ce316e77910c468108199 commit]
memcontrol: eliminate memory.current on the root level, because it doesn't add anything that wouldn't be more accurate and detailed using system statistics [https://git.kernel.org/torvalds/c/f5fc3c5d817435970aa301d066820a9ac12c8120 commit]
6. Block layer
Add Persistent Reservations support. It includes a user space interface for simplified Persistent Reservations which map to block devices that support these (only SCSI for now). Persistent Reservations allow restricting access to block devices to specific initiators in a shared storage setup [https://git.kernel.org/torvalds/c/bbd3e064362e5057cc4799ba2e4d68c7593e490b commit], [https://git.kernel.org/torvalds/c/924d55b06347d813b38c51e75ce1a6666c113933 commit], [https://git.kernel.org/torvalds/c/71cdb6978a80f9f6c51bef0622388c1414c2fe32 commit]
Add support for polling for specific IO to complete. This will be combined with request latency tracking later, so that the kernel can make qualified decisions about when to poll and when not to. For now, for benchmark purposes, a sysfs file (io_poll) is added to control whether polling is enabled or not [https://git.kernel.org/torvalds/c/05229beeddf7e75e2e616ddaad4b70e7fca9528d commit]
Export integrity data interval size in /sys/block/<disk>/integrity/protection_interval_bytes, so that apps can tell whether the interval is different from the device's logical block size [https://git.kernel.org/torvalds/c/4c241d08dbfcbdc7a949b91d72707a289d464954 commit]
cdrom: Random writing support for BD-RE media [https://git.kernel.org/torvalds/c/f7e7868b4743f1cc5e59e6e0ddd3ccf9cfe53a1b commit]
7. Cryptography
crypto: caam - add support for acipher xts(aes) [https://git.kernel.org/torvalds/c/c6415a6016bff0b547c13cadb1d5e50e9ace2be3 commit] crypto: keywrap - add key wrapping block chaining mode [https://git.kernel.org/torvalds/c/e28facde3c39005071cc5323d56539bb44efa446 commit] crypto: qat - add support for ctr(aes) and xts(aes) [https://git.kernel.org/torvalds/c/def14bfaf30d5d5a4a8fe5bf600ce09232e688c0 commit]
8. Security
9. Tracing and perf tool
Integration of perf with eBPF that, given an eBPF .c source file (or .o file built for the 'bpf' target with clang), will get it automatically built, validated and loaded into the kernel via the sys_bpf syscall, which can then be used and seen using 'perf trace' and other tools. Users can run commands like perf record --event bpf-file.c ls to try it [https://git.kernel.org/torvalds/c/69d262a93a25cf475012ea2e00aeb29f4932c028 commit], [https://git.kernel.org/torvalds/c/84c86ca12b2189df751eed7b2d67cb63bc8feda5 commit], [https://git.kernel.org/torvalds/c/ed63f34c026e9a60d17fa750ecdfe3f600d49393 commit], [https://git.kernel.org/torvalds/c/1f45b1d49073541947193bd7dac9e904142576aa commit], [https://git.kernel.org/torvalds/c/4edf30e39e6cff32390eaff6a1508969b3cd967b commit], [https://git.kernel.org/torvalds/c/71dc2326252ff1bcdddc05db03c0f831d16c9447 commit], [https://git.kernel.org/torvalds/c/d509db0473e40134286271b1d1adadccf42ac467 commit], [https://git.kernel.org/torvalds/c/aa3abf30bb28addcf593578d37447d42e3f65fc3 commit], [https://git.kernel.org/torvalds/c/1e5e3ee8ff3877db6943032b54a6ac21c095affd commit], [https://git.kernel.org/torvalds/c/ba1fae431e74bb427a699187434142fd3fe98390 commit]
Add a new branch type sampling filter to perf record, named 'call' (perf record -j call -e cycles .....), that samples only call branches (function calls), unlike 'any_call' that included direct, indirect calls and far jumps. Only x86 and PowerPC are supported in this release [https://git.kernel.org/torvalds/c/43e41adc9e8c36545888d78fed2ef8d102a938dc commit], [https://git.kernel.org/torvalds/c/c229bf9dc179d2023e185c0f705bdf68484c1e73 commit]
Add Intel cstate (aka idle states) Performance Monitoring Unit support. This allows perf to support cstate related free running (read-only and system-wide) counters. For example, to caculate the fraction of time when the core is running in C6 state: perf stat -x, -e"cstate_core/c6-residency/,msr/tsc/" -C0 -- taskset -c 0 sleep 5 [https://git.kernel.org/torvalds/c/7ce1346a6842550a3c4c453cdf1c7b81fb60b07e commit]
CPU socket filtering: perf tools introduce a new sort type "socket" for the processor socket, eg. perf report --stdio --sort socket,comm,dso,symbol [https://git.kernel.org/torvalds/c/2e7ea3ab8282f6bb1d211d8af760a734c055f493 commit]. Also, perf report introduces a --socket-filter option for 'perf report' to only show entries for a processor socket that match this filter [https://git.kernel.org/torvalds/c/21394d948a0c7c451d4a4d68afed9a06c4969636 commit]. perf hists browser can zoom in/out for processor socket [https://git.kernel.org/torvalds/c/84734b06b63093cd44533f4caa43d4452fb11ec3 commit]
perf tools: Introduce 'P' modifier, it will cause the event to get maximum possible detected precise level. For example, perf record -e cycles:P ... will detect maximum precise level for 'cycles' event and use it [https://git.kernel.org/torvalds/c/7f94af7a489fada17d28cc60e8f4409ce216bd6d commit]
perf tools: Add support for sorting on the iaddr. New sort option is: symbol_iaddr, header label is 'Code Symbol', eg perf mem report --stdio -F +symbol_iaddr [https://git.kernel.org/torvalds/c/28e6db205b3ed3f1d86a00c69b3304190377da5f commit]
perf tools: enables config terms for tracepoint perf events. Valid terms for tracepoint events are 'call-graph' and 'stack-size', so different callgraph settings can be used for each event and eliminate unnecessary overhead. An example for using different call-graph config for each tracepoint: perf record -e syscalls:sys_enter_write/call-graph=fp -e syscalls:sys_exit_write/call-graph=no dd if=/dev/zero of=test bs=4k count=10 [https://git.kernel.org/torvalds/c/e637d17757a10732fa5d573c18f20b3cd4d31245 commit]
perf script: Enable printing of branch stack viaa the 'brstack' and 'brstacksym' arguments to the field selection option -F. The option is off by default and operates only if the perf.data file has branch stack content [https://git.kernel.org/torvalds/c/dc323ce8e72d6d1beb9af9bbd29c4d55ce3d7fb0 commit]
perf auxtrace: Add AUX area tracing option 'l' to synthesize branch stacks on samples just like sample type PERF_SAMPLE_BRANCH_STACK [https://git.kernel.org/torvalds/c/601897b54c7ed492a89b262dccd7c6f7faf12b30 commit]
perf hists browser: Add 'm' key for context menu display [https://git.kernel.org/torvalds/c/31eb4360546b4bd890f349db01295a173c09b0fb commit]
perf inject: Add --strip option which is used with --itrace to strip out non-synthesized events [https://git.kernel.org/torvalds/c/f56fb9864c501dc85ebe40af5bf925dd07d990c0 commit]
perf script: Allow time to be displayed in nanoseconds [https://git.kernel.org/torvalds/c/83e1986032dfcd3f9e9fc0d06e11d9153edae19b commit]
Intel PT hardware tracer: Accept a zero --itrace period, meaning "as often as possible". In the case of Intel PT that is the same as a period of 1 and a unit of 'instructions' (i.e. --itrace=i1i)[https://git.kernel.org/torvalds/c/e1791347b5d57d13326cf0114df1a3f3b1c4ca24 commit]
Intel PT: Add support for generating branch stack context for PT samples. This is useful for: reporting accurate basic block edge frequencies through the perf report branch view or using with --branch-history to get the wider context of samples. Examples, record with Intel PT: perf record -e intel_pt//u ls
10. Virtualization
Support for VT-d posted interrupts (i.e. PCI devices can inject interrupts directly into vCPUs). Used by KVM and VFIO [https://git.kernel.org/torvalds/c/f73f8173126ba68eb1c42bd9a234a51d78576ca6 commit]
KVM: Nested virtualization now supports VPID (same as PCID but for vCPUs) which makes it quite a bit faster [https://git.kernel.org/torvalds/c/99b83ac893b84ed1a62ad6d1f2b6cc32026b9e85 commit], [https://git.kernel.org/torvalds/c/089d7b6ec5151ad06a2cd524bc0580d311b641ad commit], [https://git.kernel.org/torvalds/c/5c614b3583e7b6dab0c86356fa36c2bcbb8322a0 commit]
KVM: Support for "split irqchip", i.e. LAPIC in kernel and IOAPIC/PIC/PIT in userspace, which reduces the attack surface of the hypervisor [https://git.kernel.org/torvalds/c/b053b2aef25d00773fa6762dcd4b7f5c9c42d171 commit], [https://git.kernel.org/torvalds/c/7543a635aa09eb138b2cbf60ac3ff19503ae6954 commit], [https://git.kernel.org/torvalds/c/1c1a9ce973a7863dd46767226bce2a5f12d48bc6 commit]
KVM: add capability for any-length ioeventfds. With KVM_CAP_IOEVENTFD_ANY_LENGTH, a zero length ioeventfd is allowed, and the kernel will ignore the length of guest write and may get a faster vmexit [https://git.kernel.org/torvalds/c/e9ea5069d9e569c32ab913c39467df32e056b3a7 commit]
VMware balloon: Get notified immediately via VMCI when a balloon target is set, instead of waiting for up to one second [https://git.kernel.org/torvalds/c/48e3d668b7902cca3c61e9e2098e7f76b5646c28 commit]
VMware balloon: Support ballooning with 2 MB sized pages. It significantly reduces the hypervisor side (and guest side) overhead of ballooning and unballooning [https://git.kernel.org/torvalds/c/365bd7ef7ec8eb9c2e081cd970a5cdfa237dc243 commit]
Vmware vmxnet3: Extend register dump support [https://git.kernel.org/torvalds/c/b6bd9b5448a9362e3ca33b21f1461baa5500520f commit]
vfio: Include No-IOMMU mode. Despite the drawbacks, there are some users that want userspace drivers with vfio [https://git.kernel.org/torvalds/c/033291eccbdb1b70ffc02641edae19ac825dc75d commit]
11. Networking
[http://kb.linuxvirtualserver.org/wiki/IPVS IP Virtual Server]
Support scheduling of ICMP packets to IPVS instances. A new sysctl net.ipv4.vs.schedule_icmp has been introduced, that will enable this feature if set to 1 (by default, it is set by default to 0 to retain the old behaviour) [https://git.kernel.org/torvalds/c/99cb99aa055a72d3880d8a95a71034c4d64bcf9a merge commit]
Allow to ignore tunnelled packets with new Sysctl net.ipv4.vs.ignore_tunneled. If set, ipvs will set the ipvs_property on all packets which are of unrecognised protocols. This prevents the kernel from routing tunnelled protocols like ipip, which is useful to prevent rescheduling packets that have been tunneled to the ipvs host (i.e. to prevent ipvs routing loops when ipvs is also acting as a real server) [https://git.kernel.org/torvalds/c/4e478098ac0ac1b6ef9a70fcdc2ec8b93f1b59a1 commit]
Provide FIB table ID in ipv4 route dumps just as ipv6 does [https://git.kernel.org/torvalds/c/b7503e0cdb5dbec5d201aa69d8888c14679b5ae8 commit]
Allow the user to ask for the statistics to be filtered out of ipv4/ipv6 address netlink dumps, because many commonly used functions like getifaddrs() invoke RTM_GETLINK to dump the interface information, and do not need the AF_INET6 statistics, which are expensive to calculate [https://git.kernel.org/torvalds/c/d5566fd72ec1924958fcfd48b65c022c8f7eae64 commit]
wireless: implement Very High Throughput support for mesh networks [https://git.kernel.org/torvalds/c/c85fb53c4fa6521352028c40ce096a808aabd389 commit]
bridge: Allow setting the bridge attribute ageing_time in rocker and switchdev [https://git.kernel.org/torvalds/c/c62987bbd8a1a1664f99e89e3959339350a6131e commit], [https://git.kernel.org/torvalds/c/d0cf57f9dddb50ea404bf747a3c6b22b29f82b9a commit], [https://git.kernel.org/torvalds/c/f55ac58ae64cbb0315382e738681fe31837dcac0 commit]
vxlan: support both IPv4 and IPv6 sockets in a single vxlan device [https://git.kernel.org/torvalds/c/b1be00a6c39fda2ec380e168d7bcf96fb8c9da42 commit]
bridge: complete the bridge device's netlink support and makes it possible to view and configure everything that can be configured via sysfs [https://git.kernel.org/torvalds/c/3e087caa23ef36370bfb925d3bbca78e8302d3ce commit]
IPv4: Hash-based multipath routing. When the routing cache was [http://kernelnewbies.org/Linux_3.6#head-85de5e5247a939f2a61d0c5ccbc13ff5b4f1a6a0 removed in 3.6], the IPv4 multipath algorithm changed from more or less being destination-based into being quasi-random per-packet scheduling. This increased the risk of out-of-order packets and made it impossible to use multipath together with anycast services. In this release, the multipath routing implementation is replaced with a flow-based load balancing based on a hash over the source and destination addresses [https://git.kernel.org/torvalds/c/07355737a8badd951e6b72aa8609a2d6eed0a7e7 merge commit]
IPv6 support to the Virtual Routing and Forwarding (VRF) devices [https://git.kernel.org/torvalds/c/ccf3c8c3fe1bd4828556650ae7928da6ffb4aaf6 commit], [https://git.kernel.org/torvalds/c/35402e31366349a32b505afdfe856aeeb8d939a0 commit], [https://git.kernel.org/torvalds/c/ca254490c8dfdaddb5df8a763774db0f4c5200c3 commit]
TCP: Recent ACK (RACK) loss recovery. RACK loss recovery uses the notion of time instead of packet sequence (FACK) or counts (dupthresh) (see commit for details). In the current patch set RACK is only a supplemental loss detection and does not trigger fast recovery. However RACK is being developed to replace or consolidate FACK/dupthresh, early retransmit, and thin-dupack. Since RACK is still experimental, it is now used as a supplemental loss detection on top of existing algorithms. It can be disabled with sysctl net.ipv4.tcp_recovery [https://git.kernel.org/linus/eb9fae328faff9807a4ab5c1834b19f34dd155d4 commit]
