UPSTREAM: dma-buf: heaps: Use _IOCTL_ for userspace IOCTL identifier
This is more consistent with the DMA and DRM frameworks convention. This patch is only a name change, no logic is changed. Signed-off-by: Andrew F.

UPSTREAM: dma-buf: Add dma-buf heaps framework
This framework allows a unified userspace interface for dma-buf exporters, allowing userland to allocate specific types of memory for use in dma-buf sharing. Each heap is given its own device node, which a user can allocate a dma-buf fd from using the DMA_HEAP_IOC_ALLOC. This code is an evoluiton of the Android ION implementation, and a big thanks is due to its authors/maintainers over time for their effort: Rebecca Schultz Zavin, Colin Cross, Benjamin Gaignard, Laura Abbott, and many other contributors!

UPSTREAM: Add udmabuf misc device
A driver to let userspace turn memfd regions into dma-bufs. Use case: Allows qemu create dmabufs for the vga framebuffer or virtio-gpu ressources. Then they can be passed around to display those guest things on the host. To spice client for classic full framebuffer display, and hopefully some day to wayland server for seamless guest window display. qemu test branch: https://git.kraxel.org/cgit/qemu/log/?h=sirius/udmabuf Cc: David Airlie <airlied@linux.ie> Cc: Tomeu Vizoso <tomeu.vizoso@collabora.com> Cc: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Cc: Daniel Vetter <daniel@ffwll.ch> Change-Id: I5cce2b2f4a968f27564ea8008ff1194338b6a775 Signed-off-by: Gerd Hoffmann <kraxel@redhat.com> Acked-by: Daniel Vetter <daniel.vetter@ffwll.ch> Link: http://patchwork.freedesktop.org/patch/msgid/20180827093444.23623-1-kraxel@redhat.com |

UPSTREAM: nexthop: support for fdb ecmp nexthops
This patch introduces ecmp nexthops and nexthop groups for mac fdb entries. In subsequent patches this is used by the vxlan driver fdb entries. The use case is E-VPN multihoming [1,2,3] which requires bridged vxlan traffic to be load balanced to remote switches (vteps) belonging to the same multi-homed ethernet segment (This is analogous to a multi-homed LAG but over vxlan). Changes include new nexthop flag NHA_FDB for nexthops referenced by fdb entries. These nexthops only have ip. This patch includes appropriate checks to avoid routes referencing such nexthops. example: $ip nexthop add id 12 via 172.16.1.2 fdb $ip nexthop add id 13 via 172.16.1.3 fdb $ip nexthop add id 102 group 12/13 fdb $bridge fdb add 02:02:00:00:00:13 dev vxlan1000 nhid 101 self [1] E-VPN https://tools.ietf.org/html/rfc7432 [2] E-VPN VxLAN: https://tools.ietf.org/html/rfc8365 [3] LPC talk with mention of nexthop groups for L2 ecmp http://vger.kernel.org/lpc_net2018_talks/scaling_bridge_fdb_database_slidesV3.pdf v4 - fixed uninitialized variable reported by kernel test robot Reported-by: kernel test robot <rong.a.chen@intel.com> Change-Id: Ifcb70362fedda68775c879192a62b8cae8e574e0 Signed-off-by: Roopa Prabhu <roopa@cumulusnetworks.com> Reviewed-by: David Ahern <dsahern@gmail.com> Signed-off-by: David S.

dma-buf: Include ioctl.h in UAPI header
[ Upstream commit a116bac87118903925108e57781bbfc7a7eea27b ] include/uapi/linux/dma-buf.h uses several macros from ioctl.h to define its ioctl commands. However, it does not include ioctl.h itself. So, if userspace source code tries to include the dma-buf.h file without including ioctl.h, it can result in build failures. Therefore, include ioctl.h in the dma-buf UAPI header.

include: uapi: netfilter_bridge.h: Cover for musl libc
[ Upstream commit 4edd4ba71ce0df015303dba75ea9d20d1a217546 ] Musl defines its own struct ethhdr and thus defines __UAPI_DEF_ETHHDR to zero. To avoid struct redefinition errors, user space is therefore supposed to include netinet/if_ether.h before (or instead of) linux/if_ether.h. To relieve them from this burden, include the libc header here if not building for kernel space.

UPSTREAM: geneve: Allow configuration of DF behaviour
draft-ietf-nvo3-geneve-08 says: It is strongly RECOMMENDED that Path MTU Discovery ([RFC1191], [RFC1981]) be used by setting the DF bit in the IP header when Geneve packets are transmitted over IPv4 (this is the default with IPv6). Now that ICMP error handling is working for GENEVE, we can comply with this recommendation. Make this configurable, though, to avoid breaking existing setups. By default, DF won't be set. It can be set or inherited from inner IPv4 packets. If it's configured to be inherited and we are encapsulating IPv6, it will be set. This only applies to non-lwt tunnels: if an external control plane is used, tunnel key will still control the DF flag. v2: - DF behaviour configuration only applies for non-lwt tunnels, apply DF setting only if (!geneve->collect_md) in geneve_xmit_skb() (Stephen Hemminger) Change-Id: I8c4148083e8ab7ecc7dd134d7f490f0738a04fb6 Signed-off-by: Stefano Brivio <sbrivio@redhat.com> Reviewed-by: Sabrina Dubroca <sd@queasysnail.net> Signed-off-by: David S.

UPSTREAM: ipv4: Add "offload" and "trap" indications to routes
When performing L3 offload, routes and nexthops are usually programmed
into two different tables in the underlying device. Therefore, the fact
that a nexthop resides in hardware does not necessarily mean that all
the associated routes also reside in hardware and vice-versa.
While the kernel can signal to user space the presence of a nexthop in
hardware (via 'RTNH_F_OFFLOAD'), it does not have a corresponding flag
for routes. In addition, the fact that a route resides in hardware does
not necessarily mean that the traffic is offloaded. For example,
unreachable routes (i.e., 'RTN_UNREACHABLE') are programmed to trap
packets to the CPU so that the kernel will be able to generate the
appropriate ICMP error packet.
This patch adds an "offload" and "trap" indications to IPv4 routes, so
that users will have better visibility into the offload process.
'struct fib_alias' is extended with two new fields that indicate if the
route resides in hardware or not and if it is offloading traffic from
the kernel or trapping packets to it. Note that the new fields are added
in the 6 bytes hole and therefore the struct still fits in a single
cache line [1].
Capable drivers are expected to invoke fib_alias_hw_flags_set() with the
route's key in order to set the flags.
The indications are dumped to user space via a new flags (i.e.,
'RTM_F_OFFLOAD' and 'RTM_F_TRAP') in the 'rtm_flags' field in the
ancillary header.
v2:
* Make use of 'struct fib_rt_info' in fib_alias_hw_flags_set()
[1]
struct fib_alias {
struct hlist_node fa_list; /* 0 16 */
struct fib_info * fa_info; /* 16 8 */

UPSTREAM: net: nexthop uapi
New UAPI for nexthops as standalone objects: - defines netlink ancillary header, struct nhmsg - RTM commands for nexthop objects, RTM_*NEXTHOP, - RTNLGRP for nexthop notifications, RTNLGRP_NEXTHOP, - Attributes for creating nexthops, NHA_* - Attribute for route specs to specify a nexthop by id, RTA_NH_ID. The nexthop attributes and semantics follow the route and RTA ones for device, gateway and lwt encap. Unique to nexthop objects are a blackhole and a group which contains references to other nexthop objects. With the exception of blackhole and group, nexthop objects MUST contain a device. Gateway and encap are optional. Nexthop groups can only reference other pre-existing nexthops by id. If the NHA_ID attribute is present that id is used for the nexthop. If not specified, one is auto assigned. Dump requests can include attributes: - NHA_GROUPS to return only nexthop groups, - NHA_MASTER to limit dumps to nexthops with devices enslaved to the given master (e.g., VRF) - NHA_OIF to limit dumps to nexthops using given device nlmsg_route_perms in selinux code is updated for the new RTM comands.

macvlan: Add nodst option to macvlan type source
[ Upstream commit 427f0c8c194b22edcafef1b0a42995ddc5c2227d ] The default behavior for source MACVLAN is to duplicate packets to appropriate type source devices, and then do the normal destination MACVLAN flow. This patch adds an option to skip destination MACVLAN processing if any matching source MACVLAN device has the option set. This allows setting up a "catch all" device for source MACVLAN: create one or more devices with type source nodst, and one device with e.g. type vepa, and incoming traffic will be received on exactly one device. v2: netdev wants non-standard line length Signed-off-by: Jethro Beekman <kernel@jbeekman.nl> Signed-off-by: David S.

UPSTREAM: netlink: Add new socket option to enable strict checking on dumps
Add a new socket option, NETLINK_DUMP_STRICT_CHK, that userspace can use via setsockopt to request strict checking of headers and attributes on dump requests. To get dump features such as kernel side filtering based on data in the header or attributes appended to the dump request, userspace must call setsockopt() for NETLINK_DUMP_STRICT_CHK and a non-zero value. Since the netlink sock and its flags are private to the af_netlink code, the strict checking flag is passed to dump handlers via a flag in the netlink_callback struct. For old userspace on new kernel there is no impact as all of the data checks in later patches are wrapped in a check on the new strict flag. For new userspace on old kernel, the setsockopt will fail and even if new userspace sets data in the headers and appended attributes the kernel will silently ignore it. Moving forward when the setsockopt succeeds, the new userspace on old kernel means the dump request can pass an attribute the kernel does not understand. The dump will then fail as the older kernel does not understand it. New userspace on new kernel setting the socket option gets the benefit of the improved data dump. Kernel side the NETLINK_DUMP_STRICT_CHK uapi is converted to a generic NETLINK_F_STRICT_CHK flag which can potentially be leveraged for tighter checking on the NEW, DEL, and SET commands.

UPSTREAM: fs, close_range: add flag CLOSE_RANGE_CLOEXEC
When the flag CLOSE_RANGE_CLOEXEC is set, close_range doesn't immediately close the files but it sets the close-on-exec bit. It is useful for e.g. container runtimes that usually install a seccomp profile "as late as possible" before execv'ing the container process itself. The container runtime could either do: 1 2 - install_seccomp_profile(); - close_range(MIN_FD, MAX_INT, 0); - close_range(MIN_FD, MAX_INT, 0); - install_seccomp_profile(); - execve(...); - execve(...); Both alternative have some disadvantages. In the first variant the seccomp_profile cannot block the close_range syscall, as well as opendir/read/close/... for the fallback on older kernels. In the second variant, close_range() can be used only on the fds that are not going to be needed by the runtime anymore, and it must be potentially called multiple times to account for the different ranges that must be closed. Using close_range(..., ..., CLOSE_RANGE_CLOEXEC) solves these issues. The runtime is able to use the existing open fds, the seccomp profile can block close_range() and the syscalls used for its fallback.

UPSTREAM: close_range: add CLOSE_RANGE_UNSHARE
One of the use-cases of close_range() is to drop file descriptors just before
execve(). This would usually be expressed in the sequence:
unshare(CLONE_FILES);
close_range(3, ~0U);
as pointed out by Linus it might be desirable to have this be a part of
close_range() itself under a new flag CLOSE_RANGE_UNSHARE.
This expands {dup,unshare)_fd() to take a max_fds argument that indicates the
maximum number of file descriptors to copy from the old struct files. When the
user requests that all file descriptors are supposed to be closed via
close_range(min, max) then we can cap via unshare_fd(min) and hence don't need
to do any of the heavy fput() work for everything above min.
The patch makes it so that if CLOSE_RANGE_UNSHARE is requested and we do in
fact currently share our file descriptor table we create a new private copy.
We then close all fds in the requested range and finally after we're done we
install the new fd table.

net: netlink: add NLM_F_BULK delete request modifier
[ Upstream commit 545528d788556c724eeb5400757f828ef27782a8 ] Add a new delete request modifier called NLM_F_BULK which, when supported, would cause the request to delete multiple objects. The flag is a convenient way to signal that a multiple delete operation is requested which can be gradually added to different delete requests. In order to make sure older kernels will error out if the operation is not supported instead of doing something unintended we have to break a required condition when implementing support for this flag, f.e. for neighbors we will omit the mandatory mac address attribute. Initially it will be used to add flush with filtering support for bridge fdbs, but it also opens the door to add similar support to others.

Contains squash of this commit: Author: Nathan Chancellor <nathan@kernel.org> Date: Fri Jan 20 09:40:12 2023 -0700 ANDROID: fuse: Restore upstream type of bitfields in fuse_args Commit 88b7179fcdb59 ("ANDROID: fuse: Move functions in preparation for fuse-bpf") changed the type of these bitfields from the upstream type of 'bool' to 'int', which causes several warnings with recent versions of clang: /builds/linux/fs/fuse/dir.c:168:19: error: implicit truncation from 'int' to a one-bit wide bit-field changes value from 1 to -1 [-Werror,-Wsingle-bi t-bitfield-constant-conversion] args->out_argvar = true; ^ ~~~~ /builds/linux/fs/fuse/dir.c:492:18: error: implicit truncation from 'int' to a one-bit wide bit-field changes value from 1 to -1 [-Werror,-Wsingle-bi t-bitfield-constant-conversion] args.out_argvar = 1; ^ ~ /builds/linux/fs/fuse/dir.c:1649:20: error: implicit truncation from 'int' to a one-bit wide bit-field changes value from 1 to -1 [-Werror,-Wsingle-b it-bitfield-constant-conversion] ap.args.out_pages = true; ^ ~~~~ /builds/linux/fs/fuse/dir.c:1650:21: error: implicit truncation from 'int' to a one-bit wide bit-field changes value from 1 to -1 [-Werror,-Wsingle-b it-bitfield-constant-conversion] ap.args.out_argvar = true; ^ ~~~~ /builds/linux/fs/fuse/dir.c:1651:23: error: implicit truncation from 'int' to a one-bit wide bit-field changes value from 1 to -1 [-Werror,-Wsingle-b it-bitfield-constant-conversion] ap.args.page_zeroing = true; ^ ~~~~ 5 errors generated. When fuse_args was moved back to the internal implementation in commit 9a5023967b4d2 ("ANDROID: fuse-bpf: Use fuse_bpf_args in uapi"), the type was not restored.

UPSTREAM: virtiofs: implement dax read/write operations
This patch implements basic DAX support. mmap() is not implemented yet and will come in later patches. This patch looks into implemeting read/write. We make use of interval tree to keep track of per inode dax mappings. Do not use dax for file extending writes, instead just send WRITE message to daemon (like we do for direct I/O path). This will keep write and i_size change atomic w.r.t crash.

UPSTREAM: virtiofs: implement FUSE_INIT map_alignment field
The device communicates FUSE_SETUPMAPPING/FUSE_REMOVMAPPING alignment constraints via the FUST_INIT map_alignment field. Parse this field and ensure our DAX mappings meet the alignment constraints. We don't actually align anything differently since our mappings are already 2MB aligned. Just check the value when the connection is established. If it becomes necessary to honor arbitrary alignments in the future we'll have to adjust how mappings are sized. The upshot of this commit is that we can be confident that mappings will work even when emulating x86 on Power and similar combinations where the host page sizes are different.

UPSTREAM: virtio-fs: add virtiofs filesystem
Add a basic file system module for virtio-fs. This does not yet contain shared data support between host and guest or metadata coherency speedups. However it is already significantly faster than virtio-9p. Design Overview =============== With the goal of designing something with better performance and local file system semantics, a bunch of ideas were proposed. - Use fuse protocol (instead of 9p) for communication between guest and host. Guest kernel will be fuse client and a fuse server will run on host to serve the requests. - For data access inside guest, mmap portion of file in QEMU address space and guest accesses this memory using dax. That way guest page cache is bypassed and there is only one copy of data (on host). This will also enable mmap(MAP_SHARED) between guests. - For metadata coherency, there is a shared memory region which contains version number associated with metadata and any guest changing metadata updates version number and other guests refresh metadata on next access. This is yet to be implemented. How virtio-fs differs from existing approaches ============================================== The unique idea behind virtio-fs is to take advantage of the co-location of the virtual machine and hypervisor to avoid communication (vmexits). DAX allows file contents to be accessed without communication with the hypervisor. The shared memory region for metadata avoids communication in the common case where metadata is unchanged. By replacing expensive communication with cheaper shared memory accesses, we expect to achieve better performance than approaches based on network file system protocols. In addition, this also makes it easier to achieve local file system semantics (coherency). These techniques are not applicable to network file system protocols since the communications channel is bypassed by taking advantage of shared memory on a local machine. This is why we decided to build virtio-fs rather than focus on 9P or NFS. Caching Modes ============= Like virtio-9p, different caching modes are supported which determine the coherency level as well. The “cache=FOO” and “writeback” options control the level of coherence between the guest and host filesystems. - cache=none metadata, data and pathname lookup are not cached in guest. They are always fetched from host and any changes are immediately pushed to host. - cache=always metadata, data and pathname lookup are cached in guest and never expire. - cache=auto metadata and pathname lookup cache expires after a configured amount of time (default is 1 second). Data is cached while the file is open (close to open consistency). - writeback/no_writeback These options control the writeback strategy. If writeback is disabled, then normal writes will immediately be synchronized with the host fs. If writeback is enabled, then writes may be cached in the guest until the file is closed or an fsync(2) performed. This option has no effect on mmap-ed writes or writes going through the DAX mechanism.

UPSTREAM: iommu: Add virtio-iommu driver
The virtio IOMMU is a para-virtualized device, allowing to send IOMMU requests such as map/unmap over virtio transport without emulating page tables. This implementation handles ATTACH, DETACH, MAP and UNMAP requests. The bulk of the code transforms calls coming from the IOMMU API into corresponding virtio requests. Mappings are kept in an interval tree instead of page tables. A little more work is required for modular and x86 support, so for the moment the driver depends on CONFIG_VIRTIO=y and CONFIG_ARM64.

Works fine at the moment but might fail if a future version of fuse will use such an opcode for initialization. Let's reserve this opcode so we remember and don't do this. Same for CUSE_INIT.

UPSTREAM: fuse: reserve values for mapping protocol
SETUPMAPPING is a command for use with 'virtiofsd', a fuse-over-virtio implementation; it may find use in other fuse impelementations as well in which the kernel does not have access to the address space of the daemon directly. A SETUPMAPPING operation causes a section of a file to be mapped into a memory window visible to the kernel. The offsets in the file and the window are defined by the kernel performing the operation. The daemon may reject the request, for reasons including permissions and limited resources. When a request perfectly overlaps a previous mapping, the previous mapping is replaced. When a mapping partially overlaps a previous mapping, the previous mapping is split into one or two smaller mappings. REMOVEMAPPING is the complement to SETUPMAPPING; it unmaps a range of mapped files from the window visible to the kernel. The map_alignment field communicates the alignment constraint for FUSE_SETUPMAPPING/FUSE_REMOVEMAPPING and allows the daemon to constrain the addresses and file offsets chosen by the kernel.

UPSTREAM: fuse: add FUSE_WRITE_KILL_PRIV
In the FOPEN_DIRECT_IO case the write path doesn't call file_remove_privs() and that means setuid bit is not cleared if unpriviliged user writes to a file with setuid bit set. pjdfstest chmod test 12.t tests this and fails. Fix this by adding a flag to the FUSE_WRITE message that requests clearing privileges on the given file. This needs This better than just calling fuse_remove_privs(), because the attributes may not be up to date, so in that case a write may miss clearing the privileges. Test case: $ passthrough_ll /mnt/pasthrough-mnt -o default_permissions,allow_other,cache=never $ mkdir /mnt/pasthrough-mnt/testdir $ cd /mnt/pasthrough-mnt/testdir $ prove -rv pjdfstests/tests/chmod/12.t Reported-by: Vivek Goyal <vgoyal@redhat.com> Change-Id: Ibbdc754c6c5c96f33dc87a8a906c6c58b68b414b Signed-off-by: Miklos Szeredi <mszeredi@redhat.com> Tested-by: Vivek Goyal <vgoyal@redhat.com> |

UPSTREAM: fuse: Add ioctl flag for x32 compat ioctl
Currently, a CUSE server running on a 64-bit kernel can tell when an ioctl request comes from a process running a 32-bit ABI, but cannot tell whether the requesting process is using legacy IA32 emulation or x32 ABI. In particular, the server does not know the size of the client process's `time_t` type. For 64-bit kernels, the `FUSE_IOCTL_COMPAT` and `FUSE_IOCTL_32BIT` flags are currently set in the ioctl input request (`struct fuse_ioctl_in` member `flags`) for a 32-bit requesting process. This patch defines a new flag `FUSE_IOCTL_COMPAT_X32` and sets it if the 32-bit requesting process is using the x32 ABI. This allows the server process to distinguish between requests coming from client processes using IA32 emulation or the x32 ABI and so infer the size of the client process's `time_t` type and any other IA32/x32 differences.

BACKPORT: fuse: allow filesystems to have precise control over data cache
On networked filesystems file data can be changed externally. FUSE provides notification messages for filesystem to inform kernel that metadata or data region of a file needs to be invalidated in local page cache. That provides the basis for filesystem implementations to invalidate kernel cache explicitly based on observed filesystem-specific events. FUSE has also "automatic" invalidation mode(*) when the kernel automatically invalidates data cache of a file if it sees mtime change. It also automatically invalidates whole data cache of a file if it sees file size being changed. The automatic mode has corresponding capability - FUSE_AUTO_INVAL_DATA. However, due to probably historical reason, that capability controls only whether mtime change should be resulting in automatic invalidation or not. A change in file size always results in invalidating whole data cache of a file irregardless of whether FUSE_AUTO_INVAL_DATA was negotiated(+). The filesystem I write[1] represents data arrays stored in networked database as local files suitable for mmap. It is read-only filesystem - changes to data are committed externally via database interfaces and the filesystem only glues data into contiguous file streams suitable for mmap and traditional array processing. The files are big - starting from hundreds gigabytes and more. The files change regularly, and frequently by data being appended to their end. The size of files thus changes frequently. If a file was accessed locally and some part of its data got into page cache, we want that data to stay cached unless there is memory pressure, or unless corresponding part of the file was actually changed. However current FUSE behaviour - when it sees file size change - is to invalidate the whole file. The data cache of the file is thus completely lost even on small size change, and despite that the filesystem server is careful to accurately translate database changes into FUSE invalidation messages to kernel. Let's fix it: if a filesystem, through new FUSE_EXPLICIT_INVAL_DATA capability, indicates to kernel that it is fully responsible for data cache invalidation, then the kernel won't invalidate files data cache on size change and only truncate that cache to new size in case the size decreased.

BACKPORT: fuse: add max_pages to init_out
Replace FUSE_MAX_PAGES_PER_REQ with the configurable parameter max_pages to improve performance. Old RFC with detailed description of the problem and many fixes by Mitsuo Hayasaka (mitsuo.hayasaka.hu@hitachi.com): - https://lkml.org/lkml/2012/7/5/136 We've encountered performance degradation and fixed it on a big and complex virtual environment. Environment to reproduce degradation and improvement: 1. Add lag to user mode FUSE Add nanosleep(&(struct timespec){ 0, 1000 }, NULL); to xmp_write_buf in passthrough_fh.c 2. patch UM fuse with configurable max_pages parameter. The patch will be provided latter. 3. run test script and perform test on tmpfs fuse_test() { cd /tmp mkdir -p fusemnt passthrough_fh -o max_pages=$1 /tmp/fusemnt grep fuse /proc/self/mounts dd conv=fdatasync oflag=dsync if=/dev/zero of=fusemnt/tmp/tmp \ count=1K bs=1M 2>&1 | grep -v records rm fusemnt/tmp/tmp killall passthrough_fh } Test results: passthrough_fh /tmp/fusemnt fuse.passthrough_fh \ rw,nosuid,nodev,relatime,user_id=0,group_id=0 0 0 1073741824 bytes (1.1 GB) copied, 1.73867 s, 618 MB/s passthrough_fh /tmp/fusemnt fuse.passthrough_fh \ rw,nosuid,nodev,relatime,user_id=0,group_id=0,max_pages=256 0 0 1073741824 bytes (1.1 GB) copied, 1.15643 s, 928 MB/s Obviously with bigger lag the difference between 'before' and 'after' will be more significant.

UPSTREAM: fuse: add FOPEN_CACHE_DIR
Add flag returned by OPENDIR request to allow kernel to cache directory contents in page cache. The effect of FOPEN_CACHE_DIR is twofold: a) if not already cached, it writes entries into the cache b) if already cached, it allows reading entries from the cache The FOPEN_KEEP_CACHE has the same effect as on regular files: unless this flag is given the cache is cleared upon completion of open. So FOPEN_KEEP_CACHE and FOPEN_KEEP_CACHE flags should be used together to make use of the directory caching facility introduced in the following patches. The FUSE_AUTO_INVAL_DATA flag returned in INIT reply also has the same affect on the directory cache as it has on data cache for regular files.

UPSTREAM: bpf: Fix L4 csum update on IPv6 in CHECKSUM_COMPLETE
commit ead7f9b8de65632ef8060b84b0c55049a33cfea1 upstream.
In Cilium, we use bpf_csum_diff + bpf_l4_csum_replace to, among other
things, update the L4 checksum after reverse SNATing IPv6 packets. That
use case is however not currently supported and leads to invalid
skb->csum values in some cases. This patch adds support for IPv6 address
changes in bpf_l4_csum_update via a new flag.
When calling bpf_l4_csum_replace in Cilium, it ends up calling
inet_proto_csum_replace_by_diff:
1: void inet_proto_csum_replace_by_diff(__sum16 *sum, struct sk_buff *skb,
2: __wsum diff, bool pseudohdr)
3: {
4: if (skb->ip_summed != CHECKSUM_PARTIAL) {
5: csum_replace_by_diff(sum, diff);
6: if (skb->ip_summed == CHECKSUM_COMPLETE && pseudohdr)
7: skb->csum = ~csum_sub(diff, skb->csum);
8: } else if (pseudohdr) {
9: *sum = ~csum_fold(csum_add(diff, csum_unfold(*sum)));
10: }
11: }
The bug happens when we're in the CHECKSUM_COMPLETE state. We've just
updated one of the IPv6 addresses. The helper now updates the L4 header
checksum on line 5. Next, it updates skb->csum on line 7. It shouldn't.
For an IPv6 packet, the updates of the IPv6 address and of the L4
checksum will cancel each other. The checksums are set such that
computing a checksum over the packet including its checksum will result
in a sum of 0. So the same is true here when we update the L4 checksum
on line 5. We'll update it as to cancel the previous IPv6 address
update. Hence skb->csum should remain untouched in this case.
The same bug doesn't affect IPv4 packets because, in that case, three
fields are updated: the IPv4 address, the IP checksum, and the L4
checksum. The change to the IPv4 address and one of the checksums still
cancel each other in skb->csum, but we're left with one checksum update
and should therefore update skb->csum accordingly. That's exactly what
inet_proto_csum_replace_by_diff does.
This special case for IPv6 L4 checksums is also described atop
inet_proto_csum_replace16, the function we should be using in this case.
This patch introduces a new bpf_l4_csum_replace flag, BPF_F_IPV6,
to indicate that we're updating the L4 checksum of an IPv6 packet. When
the flag is set, inet_proto_csum_replace_by_diff will skip the
skb->csum update.
