netfilter: ip6t_srh: extend SRH matching for previous, next and last SID
IPv6 Segment Routing Header (SRH) contains a list of SIDs to be crossed by SR encapsulated packet. Each SID is encoded as an IPv6 prefix. When a Firewall receives an SR encapsulated packet, it should be able to identify which node previously processed the packet (previous SID), which node is going to process the packet next (next SID), and which node is the last to process the packet (last SID) which represent the final destination of the packet in case of inline SR mode. An example use-case of using these features could be SID list that includes two firewalls. When the second firewall receives a packet, it can check whether the packet has been processed by the first firewall or not. Based on that check, it decides to apply all rules, apply just subset of the rules, or totally skip all rules and forward the packet to the next SID. This patch extends SRH match to support matching previous SID, next SID, and last SID. Signed-off-by: Ahmed Abdelsalam <amsalam20@gmail.com> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org> |

netfilter: nft_numgen: add map lookups for numgen statements
This patch includes a new attribute in the numgen structure to allow the lookup of an element based on the number generator as a key. For this purpose, different ops have been included to extend the current numgen inc functions. Currently, only supported for numgen incremental operations, but it will be supported for random in a follow-up patch.

netfilter: add NAT support for shifted portmap ranges
This is a patch proposal to support shifted ranges in portmaps. (i.e. tcp/udp incoming port 5000-5100 on WAN redirected to LAN 192.168.1.5:2000-2100) Currently DNAT only works for single port or identical port ranges. (i.e. ports 5000-5100 on WAN interface redirected to a LAN host while original destination port is not altered) When different port ranges are configured, either 'random' mode should be used, or else all incoming connections are mapped onto the first port in the redirect range. (in described example WAN:5000-5100 will all be mapped to 192.168.1.5:2000) This patch introduces a new mode indicated by flag NF_NAT_RANGE_PROTO_OFFSET which uses a base port value to calculate an offset with the destination port present in the incoming stream. That offset is then applied as index within the redirect port range (index modulo rangewidth to handle range overflow). In described example the base port would be 5000. An incoming stream with destination port 5004 would result in an offset value 4 which means that the NAT'ed stream will be using destination port 2004. Other possibilities include deterministic mapping of larger or multiple ranges to a smaller range : WAN:5000-5999 -> LAN:5000-5099 (maps WAN port 5*xx to port 51xx) This patch does not change any current behavior. It just adds new NAT proto range functionality which must be selected via the specific flag when intended to use. A patch for iptables (libipt_DNAT.c + libip6t_DNAT.c) will also be proposed which makes this functionality immediately available.

vxlan: add ttl inherit support
Like tos inherit, ttl inherit should also means inherit the inner protocol's ttl values, which actually not implemented in vxlan yet. But we could not treat ttl == 0 as "use the inner TTL", because that would be used also when the "ttl" option is not specified and that would be a behavior change, and breaking real use cases. So add a different attribute IFLA_VXLAN_TTL_INHERIT when "ttl inherit" is specified with ip cmd.

linux/const.h: move UL() macro to include/linux/const.h
ARM, ARM64 and UniCore32 duplicate the definition of UL(): #define UL(x) _AC(x, UL) This is not actually arch-specific, so it will be useful to move it to a common header. Currently, we only have the uapi variant for linux/const.h, so I am creating include/linux/const.h. I also added _UL(), _ULL() and ULL() because _AC() is mostly used in the form either _AC(..., UL) or _AC(..., ULL). I expect they will be replaced in follow-up cleanups. The underscore-prefixed ones should be used for exported headers.

linux/const.h: prefix include guard of uapi/linux/const.h with _UAPI
Patch series "linux/const.h: cleanups of macros such as UL(), _BITUL(), BIT() etc", v3. ARM, ARM64, UniCore32 define UL() as a shorthand of _AC(..., UL). More architectures may introduce it in the future. UL() is arch-agnostic, and useful. So let's move it to include/linux/const.h Currently, <asm/memory.h> must be included to use UL(). It pulls in more bloats just for defining some bit macros. I posted V2 one year ago. The previous posts are: https://patchwork.kernel.org/patch/9498273/ https://patchwork.kernel.org/patch/9498275/ https://patchwork.kernel.org/patch/9498269/ https://patchwork.kernel.org/patch/9498271/ At that time, what blocked this series was a comment from David Howells: You need to be very careful doing this. Some userspace stuff depends on the guard macro names on the kernel header files. (https://patchwork.kernel.org/patch/9498275/) Looking at the code closer, I noticed this is not a problem. See the following line. https://github.com/torvalds/linux/blob/v4.16-rc2/scripts/headers_install.sh#L40 scripts/headers_install.sh rips off _UAPI prefix from guard macro names. I ran "make headers_install" and confirmed the result is what I expect. So, we can prefix the include guard of include/uapi/linux/const.h, and add a new include/linux/const.h. This patch (of 4): I am going to add include/linux/const.h for the kernel space. Add _UAPI to the include guard of include/uapi/linux/const.h to prepare for that. Please notice the guard name of the exported one will be kept as-is. So, this commit has no impact to the userspace even if some userspace stuff depends on the guard macro names. scripts/headers_install.sh processes exported headers by SED, and rips off "_UAPI" from guard macro names. #ifndef _UAPI_LINUX_CONST_H #define _UAPI_LINUX_CONST_H will be turned into #ifndef _LINUX_CONST_H #define _LINUX_CONST_H Link: http://lkml.kernel.org/r/1519301715-31798-2-git-send-email-yamada.masahiro@socionext.com Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> Cc: David Howells <dhowells@redhat.com> Cc: Will Deacon <will.deacon@arm.com> Cc: Guan Xuetao <gxt@mprc.pku.edu.cn> Cc: Geert Uytterhoeven <geert@linux-m68k.org> Cc: Catalin Marinas <catalin.marinas@arm.com> Cc: Russell King <rmk+kernel@armlinux.org.uk> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> |

ipc/msg: introduce msgctl(MSG_STAT_ANY)
There is a permission discrepancy when consulting msq ipc object metadata between /proc/sysvipc/msg (0444) and the MSG_STAT shmctl command. The later does permission checks for the object vs S_IRUGO. As such there can be cases where EACCESS is returned via syscall but the info is displayed anyways in the procfs files. While this might have security implications via info leaking (albeit no writing to the msq metadata), this behavior goes way back and showing all the objects regardless of the permissions was most likely an overlook - so we are stuck with it. Furthermore, modifying either the syscall or the procfs file can cause userspace programs to break (ie ipcs). Some applications require getting the procfs info (without root privileges) and can be rather slow in comparison with a syscall -- up to 500x in some reported cases for shm. This patch introduces a new MSG_STAT_ANY command such that the msq ipc object permissions are ignored, and only audited instead. In addition, I've left the lsm security hook checks in place, as if some policy can block the call, then the user has no other choice than just parsing the procfs file.

ipc/shm: introduce shmctl(SHM_STAT_ANY)
Patch series "sysvipc: introduce STAT_ANY commands", v2. The following patches adds the discussed (see [1]) new command for shm as well as for sems and msq as they are subject to the same discrepancies for ipc object permission checks between the syscall and via procfs. These new commands are justified in that (1) we are stuck with this semantics as changing syscall and procfs can break userland; and (2) some users can benefit from performance (for large amounts of shm segments, for example) from not having to parse the procfs interface. Once merged, I will submit the necesary manpage updates. But I'm thinking something like: : diff --git a/man2/shmctl.2 b/man2/shmctl.2 : index 7bb503999941..bb00bbe21a57 100644 : --- a/man2/shmctl.2 : +++ b/man2/shmctl.2 : @@ -41,6 +41,7 @@ : .\" 2005-04-25, mtk -- noted aberrant Linux behavior w.r.t. new : .\" attaches to a segment that has already been marked for deletion. : .\" 2005-08-02, mtk: Added IPC_INFO, SHM_INFO, SHM_STAT descriptions. : +.\" 2018-02-13, dbueso: Added SHM_STAT_ANY description. : .\" : .TH SHMCTL 2 2017-09-15 "Linux" "Linux Programmer's Manual" : .SH NAME : @@ -242,6 +243,18 @@ However, the : argument is not a segment identifier, but instead an index into : the kernel's internal array that maintains information about : all shared memory segments on the system. : +.TP : +.BR SHM_STAT_ANY " (Linux-specific)" : +Return a : +.I shmid_ds : +structure as for : +.BR SHM_STAT . : +However, the : +.I shm_perm.mode : +is not checked for read access for : +.IR shmid , : +resembing the behaviour of : +/proc/sysvipc/shm. : .PP : The caller can prevent or allow swapping of a shared : memory segment with the following \fIcmd\fP values: : @@ -287,7 +300,7 @@ operation returns the index of the highest used entry in the : kernel's internal array recording information about all : shared memory segments. : (This information can be used with repeated : -.B SHM_STAT : +.B SHM_STAT/SHM_STAT_ANY : operations to obtain information about all shared memory segments : on the system.) : A successful : @@ -328,7 +341,7 @@ isn't accessible. : \fIshmid\fP is not a valid identifier, or \fIcmd\fP : is not a valid command. : Or: for a : -.B SHM_STAT : +.B SHM_STAT/SHM_STAT_ANY : operation, the index value specified in : .I shmid : referred to an array slot that is currently unused.

Pull SELinux updates from Paul Moore:
"A bigger than usual pull request for SELinux, 13 patches (lucky!)
along with a scary looking diffstat.
Although if you look a bit closer, excluding the usual minor
tweaks/fixes, there are really only two significant changes in this
pull request: the addition of proper SELinux access controls for SCTP
and the encapsulation of a lot of internal SELinux state.
The SCTP changes are the result of a multi-month effort (maybe even a
year or longer?) between the SELinux folks and the SCTP folks to add
proper SELinux controls. A special thanks go to Richard for seeing
this through and keeping the effort moving forward.
The state encapsulation work is a bit of janitorial work that came out
of some early work on SELinux namespacing. The question of namespacing
is still an open one, but I believe there is some real value in the
encapsulation work so we've split that out and are now sending that up
to you"

- DM core passthrough ioctl fix to retain reference to DM table, and
that table's block devices, while issuing the ioctl to one of those block devices. - DM core passthrough ioctl fix to _not_ override the fmode_t used to issue the ioctl. Overriding by using the fmode_t that the block device was originally open with during DM table load is a liability. - Add DM core support for secure erase forwarding and update the DM linear and DM striped targets to support them. - A DM core 4.16 stable fix to allow abnormal IO (e.g. discard, write same, write zeroes) for targets that make use of the non-splitting IO variant (as is done for multipath or thinp when layered directly on NVMe). - Allow DM targets to return a payload in response to a DM message that they are sent. This is useful for DM targets that would like to provide statistics data in response to DM messages. - Update DM bufio to support non-power-of-2 block sizes. Numerous other related changes prepare the DM bufio code for this support. - Fix DM crypt to use a bounded amount of memory across the entire system. This is to avoid OOM that can otherwise occur in response to certain pathological IO workloads (e.g. discarding a large DM crypt device). - Add a 'check_at_most_once' feature to the DM verity target to allow verity to be used on mobile devices that have very limited resources. - Fix the DM integrity target to fail early if a keyed algorithm (e.g. HMAC) is to be used but the key isn't set. - Add non-power-of-2 support to the DM unstripe target. - Eliminate the use of a Variable Length Array in the DM stripe target. - Update the DM log-writes target to record metadata (REQ_META flag). - DM raid fixes for its nosync status and some variable range issues. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQEcBAABAgAGBQJaxjrCAAoJEMUj8QotnQNaEW8IAMeb6dWbxBgCleafK7GV5I0B jdm6NWDGoGrhz5TyZXbd6pLXD6fbU51O2Jn/LyQ7KOY1lRlS66TBprR60gNyzPQn bQVVEbKnSMwNAnkVpStiVZSs2e9HyNIRsM0yvwZXPfcVw6Q8XttiJQHRdGu4A5jm i+/aoyAf1iJowe5ituyE569gFGnOzPmesKZoF2/A36ik3yq3HF4FR0IPxWKseSpt gCeGTPpBv3aRonRBDxT9uOwb3SXC8TGrStRLm1I6UFwmHKs7nWx/o/P1ghbSOgSt Gu+GdoXnG5qtzAZ1t3sR2Iw3zEmpO1t5Jht5VqR7T+1145DaoPkW5M8vyjHll5o= =H7V5 -----END PGP SIGNATURE----- Merge tag 'for-4.17/dm-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm Pull device mapper updates from Mike Snitzer: - DM core passthrough ioctl fix to retain reference to DM table, and that table's block devices, while issuing the ioctl to one of those block devices. - DM core passthrough ioctl fix to _not_ override the fmode_t used to issue the ioctl.

sound updates for 4.17-rc1
This became a large update. The changes are scattered widely,
and majority of them are attributed to ASoC componentization.
The gitk output made me dizzy, but it's slightly better than
London tube.
OK, below are some highlights:
- Continued hardening works in ALSA PCM core; most of the
existing syzkaller reports should have been covered.
- USB-audio got the initial USB Audio Class 3 support, as well
as UAC2 jack detection support and more DSD-device support.
- ASoC componentization: finally each individual driver was
converted to components framework, which is more future-proof
for further works. Most of conversations were systematic.
- Lots of fixes for Intel Baytrail / Cherrytrail devices with
Realtek codecs, typically tablets and small PCs.
- Fixes / cleanups for Samsung Odroid systems
- Cleanups in Freescale SSI driver
- New ASoC drivers:
* AKM AK4458 and AK5558 codecs
* A few AMD based machine drivers
* Intel Kabylake machine drivers
* Maxim MAX9759 codec
* Motorola CPCAP codec
* Socionext Uniphier SoCs
* TI PCM1789 and TDA7419 codecs
- Retirement of Blackfin drivers along with architecture removal.

Pull sound updates from Takashi Iwai:
"This became a large update. The changes are scattered widely, and the
majority of them are attributed to ASoC componentization. The gitk
output made me dizzy, but it's slightly better than London tube.
OK, below are some highlights:
- Continued hardening works in ALSA PCM core; most of the existing
syzkaller reports should have been covered.
- USB-audio got the initial USB Audio Class 3 support, as well as
UAC2 jack detection support and more DSD-device support.
- ASoC componentization: finally each individual driver was converted
to components framework, which is more future-proof for further
works. Most of conversations were systematic.
- Lots of fixes for Intel Baytrail / Cherrytrail devices with Realtek
codecs, typically tablets and small PCs.
- Fixes / cleanups for Samsung Odroid systems
- Cleanups in Freescale SSI driver
- New ASoC drivers:
* AKM AK4458 and AK5558 codecs
* A few AMD based machine drivers
* Intel Kabylake machine drivers
* Maxim MAX9759 codec
* Motorola CPCAP codec
* Socionext Uniphier SoCs
* TI PCM1789 and TDA7419 codecs
- Retirement of Blackfin drivers along with architecture removal"

Merge branch 'timers-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull time(r) updates from Thomas Gleixner:
"A small set of updates for timers and timekeeping:
- The most interesting change is the consolidation of clock MONOTONIC
and clock BOOTTIME.
Clock MONOTONIC behaves now exactly like clock BOOTTIME and does
not longer ignore the time spent in suspend. A new clock
MONOTONIC_ACTIVE is provived which behaves like clock MONOTONIC in
kernels before this change. This allows applications to
programmatically check for the clock MONOTONIC behaviour.
As discussed in the review thread, this has the potential of
breaking user space and we might have to revert this. Knock on wood
that we can avoid that exercise.
- Updates to the NTP mechanism to improve accuracy
- A new kernel internal data structure to aid the ongoing Y2038 work.
- Cleanups and simplifications of the clocksource code.
- Make the alarmtimer code play nicely with debugobjects"

arch: remove obsolete architecture ports
This removes the entire architecture code for blackfin, cris, frv, m32r, metag, mn10300, score, and tile, including the associated device drivers. I have been working with the (former) maintainers for each one to ensure that my interpretation was right and the code is definitely unused in mainline kernels. Many had fond memories of working on the respective ports to start with and getting them included in upstream, but also saw no point in keeping the port alive without any users. In the end, it seems that while the eight architectures are extremely different, they all suffered the same fate: There was one company in charge of an SoC line, a CPU microarchitecture and a software ecosystem, which was more costly than licensing newer off-the-shelf CPU cores from a third party (typically ARM, MIPS, or RISC-V). It seems that all the SoC product lines are still around, but have not used the custom CPU architectures for several years at this point. In contrast, CPU instruction sets that remain popular and have actively maintained kernel ports tend to all be used across multiple licensees.

Pull perf updates from Ingo Molnar:
"The main kernel side changes were:
- Modernize the kprobe and uprobe creation/destruction tooling ABIs:
The existing text based APIs (kprobe_events and uprobe_events in
tracefs), are naive, limited ABIs in that they require user-space
to clean up after themselves, which is both difficult and fragile
if the tool is buggy or exits unexpectedly. In other words they are
not really suited for modern, robust tooling.
So introduce a modern, file descriptor based ABI that does not have
these limitations: introduce the 'perf_kprobe' and 'perf_uprobe'
PMUs and extend the perf_event_open() syscall to create events with
a kprobe/uprobe attached to them. These [k,u]probe are associated
with this file descriptor, so they are not available in tracefs.

ASoC: Updates for v4.17
This is a *very* big release for ASoC. Not much change in the core but
there s the transition of all the individual drivers over to components
which is intended to support further core work. The goal is to make it
easier to do further core work by removing the need to special case all
the different driver classes in the core, many of the devices end up
being used in multiple roles in modern systems.
We also have quite a lot of new drivers added this month of all kinds,
quite a few for simple devices but also some more advanced ones with
more substantial code.
- The biggest thing is the huge series from Morimoto-san which
converted everything over to components. This is a huge change by
code volume but was fairly mechanical
- Many fixes for some of the Realtek based Baytrail systems covering
both the CODECs and the CPUs, contributed by Hans de Goode.
- Lots of cleanups for Samsung based Odroid systems from Sylwester
Nawrocki.
- The Freescale SSI driver also got a lot of cleanups from Nicolin
Chen.
- The Blackfin drivers have been removed as part of the removal of the
architecture.
- New drivers for AKM AK4458 and AK5558, several AMD based machines,
several Intel based machines, Maxim MAX9759, Motorola CPCAP,
Socionext Uniphier SoCs, and TI PCM1789 and TDA7419

Merge git://git.kernel.org/pub/scm/linux/kernel/git/bpf/bpf-next
Daniel Borkmann says:
====================
pull-request: bpf-next 2018-03-31
The following pull-request contains BPF updates for your *net-next* tree.
The main changes are:
1) Add raw BPF tracepoint API in order to have a BPF program type that
can access kernel internal arguments of the tracepoints in their
raw form similar to kprobes based BPF programs. This infrastructure
also adds a new BPF_RAW_TRACEPOINT_OPEN command to BPF syscall which
returns an anon-inode backed fd for the tracepoint object that allows
for automatic detach of the BPF program resp. unregistering of the
tracepoint probe on fd release, from Alexei.
2) Add new BPF cgroup hooks at bind() and connect() entry in order to
allow BPF programs to reject, inspect or modify user space passed
struct sockaddr, and as well a hook at post bind time once the port
has been allocated. They are used in FB's container management engine
for implementing policy, replacing fragile LD_PRELOAD wrapper
intercepting bind() and connect() calls that only works in limited
scenarios like glibc based apps but not for other runtimes in
containerized applications, from Andrey.
3) BPF_F_INGRESS flag support has been added to sockmap programs for
their redirect helper call bringing it in line with cls_bpf based
programs. Support is added for both variants of sockmap programs,
meaning for tx ULP hooks as well as recv skb hooks, from John.
4) Various improvements on BPF side for the nfp driver, besides others
this work adds BPF map update and delete helper call support from
the datapath, JITing of 32 and 64 bit XADD instructions as well as
offload support of bpf_get_prandom_u32() call. Initial implementation
of nfp packet cache has been tackled that optimizes memory access
(see merge commit for further details), from Jakub and Jiong.
5) Removal of struct bpf_verifier_env argument from the print_bpf_insn()
API has been done in order to prepare to use print_bpf_insn() soon
out of perf tool directly. This makes the print_bpf_insn() API more
generic and pushes the env into private data. bpftool is adjusted
as well with the print_bpf_insn() argument removal, from Jiri.
6) Couple of cleanups and prep work for the upcoming BTF (BPF Type
Format). The latter will reuse the current BPF verifier log as
well, thus bpf_verifier_log() is further generalized, from Martin.
7) For bpf_getsockopt() and bpf_setsockopt() helpers, IPv4 IP_TOS read
and write support has been added in similar fashion to existing
IPv6 IPV6_TCLASS socket option we already have, from Nikita.
8) Fixes in recent sockmap scatterlist API usage, which did not use
sg_init_table() for initialization thus triggering a BUG_ON() in
scatterlist API when CONFIG_DEBUG_SG was enabled. This adds and
uses a small helper sg_init_marker() to properly handle the affected
cases, from Prashant.
9) Let the BPF core follow IDR code convention and therefore use the
idr_preload() and idr_preload_end() helpers, which would also help
idr_alloc_cyclic() under GFP_ATOMIC to better succeed under memory
pressure, from Shaohua.
10) Last but not least, a spelling fix in an error message for the
BPF cookie UID helper under BPF sample code, from Colin.

tipc: avoid possible string overflow
gcc points out that the combined length of the fixed-length inputs to
l->name is larger than the destination buffer size:
net/tipc/link.c: In function 'tipc_link_create':
net/tipc/link.c:465:26: error: '%s' directive writing up to 32 bytes
into a region of size between 26 and 58 [-Werror=format-overflow=]
sprintf(l->name, "%s:%s-%s:unknown", self_str, if_name, peer_str);
net/tipc/link.c:465:2: note: 'sprintf' output 11 or more bytes
(assuming 75) into a destination of size 60
sprintf(l->name, "%s:%s-%s:unknown", self_str, if_name, peer_str);
A detailed analysis reveals that the theoretical maximum length of
a link name is:
max self_str + 1 + max if_name + 1 + max peer_str + 1 + max if_name =
16 + 1 + 15 + 1 + 16 + 1 + 15 = 65
Since we also need space for a trailing zero we now set MAX_LINK_NAME
to 68.
Just to be on the safe side we also replace the sprintf() call with
snprintf().

bpf: Post-hooks for sys_bind
"Post-hooks" are hooks that are called right before returning from sys_bind. At this time IP and port are already allocated and no further changes to `struct sock` can happen before returning from sys_bind but BPF program has a chance to inspect the socket and change sys_bind result. Specifically it can e.g. inspect what port was allocated and if it doesn't satisfy some policy, BPF program can force sys_bind to fail and return EPERM to user. Another example of usage is recording the IP:port pair to some map to use it in later calls to sys_connect. E.g. if some TCP server inside cgroup was bound to some IP:port_n, it can be recorded to a map. And later when some TCP client inside same cgroup is trying to connect to 127.0.0.1:port_n, BPF hook for sys_connect can override the destination and connect application to IP:port_n instead of 127.0.0.1:port_n. That helps forcing all applications inside a cgroup to use desired IP and not break those applications if they e.g. use localhost to communicate between each other. == Implementation details == Post-hooks are implemented as two new attach types `BPF_CGROUP_INET4_POST_BIND` and `BPF_CGROUP_INET6_POST_BIND` for existing prog type `BPF_PROG_TYPE_CGROUP_SOCK`. Separate attach types for IPv4 and IPv6 are introduced to avoid access to IPv6 field in `struct sock` from `inet_bind()` and to IPv4 field from `inet6_bind()` since those fields might not make sense in such cases.

bpf: Hooks for sys_connect
== The problem == See description of the problem in the initial patch of this patch set. == The solution == The patch provides much more reliable in-kernel solution for the 2nd part of the problem: making outgoing connecttion from desired IP. It adds new attach types `BPF_CGROUP_INET4_CONNECT` and `BPF_CGROUP_INET6_CONNECT` for program type `BPF_PROG_TYPE_CGROUP_SOCK_ADDR` that can be used to override both source and destination of a connection at connect(2) time. Local end of connection can be bound to desired IP using newly introduced BPF-helper `bpf_bind()`. It allows to bind to only IP though, and doesn't support binding to port, i.e. leverages `IP_BIND_ADDRESS_NO_PORT` socket option. There are two reasons for this: * looking for a free port is expensive and can affect performance significantly; * there is no use-case for port. As for remote end (`struct sockaddr *` passed by user), both parts of it can be overridden, remote IP and remote port. It's useful if an application inside cgroup wants to connect to another application inside same cgroup or to itself, but knows nothing about IP assigned to the cgroup. Support is added for IPv4 and IPv6, for TCP and UDP. IPv4 and IPv6 have separate attach types for same reason as sys_bind hooks, i.e. to prevent reading from / writing to e.g. user_ip6 fields when user passes sockaddr_in since it'd be out-of-bound. == Implementation notes == The patch introduces new field in `struct proto`: `pre_connect` that is a pointer to a function with same signature as `connect` but is called before it. The reason is in some cases BPF hooks should be called way before control is passed to `sk->sk_prot->connect`. Specifically `inet_dgram_connect` autobinds socket before calling `sk->sk_prot->connect` and there is no way to call `bpf_bind()` from hooks from e.g. `ip4_datagram_connect` or `ip6_datagram_connect` since it'd cause double-bind. On the other hand `proto.pre_connect` provides a flexible way to add BPF hooks for connect only for necessary `proto` and call them at desired time before `connect`. Since `bpf_bind()` is allowed to bind only to IP and autobind in `inet_dgram_connect` binds only port there is no chance of double-bind. bpf_bind() sets `force_bind_address_no_port` to bind to only IP despite of value of `bind_address_no_port` socket field. bpf_bind() sets `with_lock` to `false` when calling to __inet_bind() and __inet6_bind() since all call-sites, where bpf_bind() is called, already hold socket lock.

bpf: Hooks for sys_bind
== The problem == There is a use-case when all processes inside a cgroup should use one single IP address on a host that has multiple IP configured. Those processes should use the IP for both ingress and egress, for TCP and UDP traffic. So TCP/UDP servers should be bound to that IP to accept incoming connections on it, and TCP/UDP clients should make outgoing connections from that IP. It should not require changing application code since it's often not possible. Currently it's solved by intercepting glibc wrappers around syscalls such as `bind(2)` and `connect(2)`. It's done by a shared library that is preloaded for every process in a cgroup so that whenever TCP/UDP server calls `bind(2)`, the library replaces IP in sockaddr before passing arguments to syscall. When application calls `connect(2)` the library transparently binds the local end of connection to that IP (`bind(2)` with `IP_BIND_ADDRESS_NO_PORT` to avoid performance penalty). Shared library approach is fragile though, e.g.: * some applications clear env vars (incl. `LD_PRELOAD`); * `/etc/ld.so.preload` doesn't help since some applications are linked with option `-z nodefaultlib`; * other applications don't use glibc and there is nothing to intercept. == The solution == The patch provides much more reliable in-kernel solution for the 1st part of the problem: binding TCP/UDP servers on desired IP. It does not depend on application environment and implementation details (whether glibc is used or not). It adds new eBPF program type `BPF_PROG_TYPE_CGROUP_SOCK_ADDR` and attach types `BPF_CGROUP_INET4_BIND` and `BPF_CGROUP_INET6_BIND` (similar to already existing `BPF_CGROUP_INET_SOCK_CREATE`). The new program type is intended to be used with sockets (`struct sock`) in a cgroup and provided by user `struct sockaddr`. Pointers to both of them are parts of the context passed to programs of newly added types. The new attach types provides hooks in `bind(2)` system call for both IPv4 and IPv6 so that one can write a program to override IP addresses and ports user program tries to bind to and apply such a program for whole cgroup. == Implementation notes == [1] Separate attach types for `AF_INET` and `AF_INET6` are added intentionally to prevent reading/writing to offsets that don't make sense for corresponding socket family. E.g. if user passes `sockaddr_in` it doesn't make sense to read from / write to `user_ip6[]` context fields. [2] The write access to `struct bpf_sock_addr_kern` is implemented using special field as an additional "register". There are just two registers in `sock_addr_convert_ctx_access`: `src` with value to write and `dst` with pointer to context that can't be changed not to break later instructions. But the fields, allowed to write to, are not available directly and to access them address of corresponding pointer has to be loaded first. To get additional register the 1st not used by `src` and `dst` one is taken, its content is saved to `bpf_sock_addr_kern.tmp_reg`, then the register is used to load address of pointer field, and finally the register's content is restored from the temporary field after writing `src` value.

bpf: Check attach type at prog load time
== The problem == There are use-cases when a program of some type can be attached to multiple attach points and those attach points must have different permissions to access context or to call helpers. E.g. context structure may have fields for both IPv4 and IPv6 but it doesn't make sense to read from / write to IPv6 field when attach point is somewhere in IPv4 stack. Same applies to BPF-helpers: it may make sense to call some helper from some attach point, but not from other for same prog type. == The solution == Introduce `expected_attach_type` field in in `struct bpf_attr` for `BPF_PROG_LOAD` command. If scenario described in "The problem" section is the case for some prog type, the field will be checked twice: 1) At load time prog type is checked to see if attach type for it must be known to validate program permissions correctly. Prog will be rejected with EINVAL if it's the case and `expected_attach_type` is not specified or has invalid value. 2) At attach time `attach_type` is compared with `expected_attach_type`, if prog type requires to have one, and, if they differ, attach will be rejected with EINVAL. The `expected_attach_type` is now available as part of `struct bpf_prog` in both `bpf_verifier_ops->is_valid_access()` and `bpf_verifier_ops->get_func_proto()` () and can be used to check context accesses and calls to helpers correspondingly.

blktrace: fix comment in blktrace_api.h
The `__u64 time` field of the blk_io_trace struct refers to
the time in nanoseconds, not in microseconds. It is set in
__blk_add_trace, which does the following:
t->time = ktime_to_ns(ktime_get());
ktime_to_ns returns ktime_t in nanoseconds, not microseconds.

====================
Netfilter/IPVS updates for net-next
The following patchset contains Netfilter/IPVS updates for your net-next
tree. This batch comes with more input sanitization for xtables to
address bug reports from fuzzers, preparation works to the flowtable
infrastructure and assorted updates. In no particular order, they are:
1) Make sure userspace provides a valid standard target verdict, from
Florian Westphal.
2) Sanitize error target size, also from Florian.
3) Validate that last rule in basechain matches underflow/policy since
userspace assumes this when decoding the ruleset blob that comes
from the kernel, from Florian.
4) Consolidate hook entry checks through xt_check_table_hooks(),
patch from Florian.
5) Cap ruleset allocations at 512 mbytes, 134217728 rules and reject
very large compat offset arrays, so we have a reasonable upper limit
and fuzzers don't exercise the oom-killer. Patches from Florian.
6) Several WARN_ON checks on xtables mutex helper, from Florian.
7) xt_rateest now has a hashtable per net, from Cong Wang.
8) Consolidate counter allocation in xt_counters_alloc(), from Florian.
9) Earlier xt_table_unlock() call in {ip,ip6,arp,eb}tables, patch
from Xin Long.
10) Set FLOW_OFFLOAD_DIR_* to IP_CT_DIR_* definitions, patch from
Felix Fietkau.
11) Consolidate code through flow_offload_fill_dir(), also from Felix.
12) Inline ip6_dst_mtu_forward() just like ip_dst_mtu_maybe_forward()
to remove a dependency with flowtable and ipv6.ko, from Felix.
13) Cache mtu size in flow_offload_tuple object, this is safe for
forwarding as

netfilter: ebtables: Add support for specifying match revision
Currently ebtables assumes that the revision number of all match modules is 0, which is an issue when trying to use existing xtables matches with ebtables. The solution is to modify ebtables to allow extensions to specify a revision number, similar to iptables. This gets passed down to the kernel, which is then able to find the match module correctly. To main binary backwards compatibility, the size of the ebt_entry structures is not changed, only the size of the name field is decreased by 1 byte to make room for the revision field.

We have a fair number of patches, but many of them are from the
first bullet here:
* EAPoL-over-nl80211 from Denis - this will let us fix
some long-standing issues with bridging, races with
encryption and more
* DFS offload support from the qtnfmac folks
* regulatory database changes for the new ETSI adaptivity
requirements
* various other fixes and small enhancements
