Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

[NET]: move config options out to individual protocols Move the protocol specific config options out to the specific protocols. With this change net/Kconfig now starts to become readable and serve as a good basis for further re-structuring. The menu structure is left almost intact, except that indention is fixed in most cases. Most visible are the INET changes where several "depends on INET" are replaced with a single ifdef INET / endif pair. Several new files were created to accomplish this change - they are small but serve the purpose that config options are now distributed out where they belongs.

net: Build IPv6 into kernel by default This patch makes the default to build IPv6 into the kernel. IPv6 now has significant traction and any remaining vestiges of IPv6 not being provided parity with IPv4 should be swept away. IPv6 is now core to the Internet and kernel. Points on IPv6 adoption: - Per Google statistics, IPv6 usage has reached 7% on the Internet and continues to exhibit an exponential growth rate https://www.google.com/intl/en/ipv6/statistics.html - Just a few days ago ARIN officially depleted its IPv4 pool - IPv6 only data centers are being successfully built (e.g. at Facebook) This patch changes the IPv6 Kconfig for IPV6. Default for CONFIG_IPV6 is set to "y" and the text has been updated to reflect the maturity of IPv6. Impact: Under some circumstances building modules in to kernel might have a performance advantage. In my testing, I did notice a very slight improvement. This will obviously increase the size of the kernel image. In my configuration I see: IPv6 as module: text data bss dec hex filename 9703666 1899288 933888 12536842 bf4c0a vmlinux IPv6 built into kernel text data bss dec hex filename 9436490 1879600 913408 12229498 ba9b7a vmlinux Which increases text size by ~270K (2.8% increase in size for me). If image size is an issue, presumably for a device which does not do IP networking (IMO we should be discouraging IPv4-only devices), IPV6 can be disabled or still built as a module.

crypto: lib - make the sha1 library optional Since the Linux RNG no longer uses sha1_transform(), the SHA-1 library is no longer needed unconditionally. Make it possible to build the Linux kernel without the SHA-1 library by putting it behind a kconfig option, and selecting this new option from the kconfig options that gate the remaining users: CRYPTO_SHA1 for crypto/sha1_generic.c, BPF for kernel/bpf/core.c, and IPV6 for net/ipv6/addrconf.c. Unfortunately, since BPF is selected by NET, for now this can only make a difference for kernels built without networking support.

esp, ah: modernize the crypto algorithm selections The crypto algorithms selected by the ESP and AH kconfig options are out-of-date with the guidance of RFC 8221, which lists the legacy algorithms MD5 and DES as "MUST NOT" be implemented, and some more modern algorithms like AES-GCM and HMAC-SHA256 as "MUST" be implemented. But the options select the legacy algorithms, not the modern ones. Therefore, modify these options to select the MUST algorithms -- and *only* the MUST algorithms. Also improve the help text. Note that other algorithms may still be explicitly enabled in the kconfig, and the choice of which to actually use is still controlled by userspace. This change only modifies the list of algorithms for which kernel support is guaranteed to be present.

esp, ah: modernize the crypto algorithm selections The crypto algorithms selected by the ESP and AH kconfig options are out-of-date with the guidance of RFC 8221, which lists the legacy algorithms MD5 and DES as "MUST NOT" be implemented, and some more modern algorithms like AES-GCM and HMAC-SHA256 as "MUST" be implemented. But the options select the legacy algorithms, not the modern ones. Therefore, modify these options to select the MUST algorithms -- and *only* the MUST algorithms. Also improve the help text. Note that other algorithms may still be explicitly enabled in the kconfig, and the choice of which to actually use is still controlled by userspace. This change only modifies the list of algorithms for which kernel support is guaranteed to be present.

xfrm: add IPv6 support for espintcp This extends espintcp to support IPv6, building on the existing code and the new UDPv6 encapsulation support. Most of the code is either reused directly (stream parser, ULP) or very similar to the IPv4 variant (net/ipv6/esp6.c changes). The separation of config options for IPv4 and IPv6 espintcp requires a bit of Kconfig gymnastics to enable the core code.

[INET]: Introduce tunnel4/tunnel6 Basically this patch moves the generic tunnel protocol stuff out of xfrm4_tunnel/xfrm6_tunnel and moves it into the new files of tunnel4.c and tunnel6 respectively. The reason for this is that the problem that Hugo uncovered is only the tip of the iceberg. The real problem is that when we removed the dependency of ipip on xfrm4_tunnel we didn't really consider the module case at all. For instance, as it is it's possible to build both ipip and xfrm4_tunnel as modules and if the latter is loaded then ipip simply won't load. After considering the alternatives I've decided that the best way out of this is to restore the dependency of ipip on the non-xfrm-specific part of xfrm4_tunnel. This is acceptable IMHO because the intention of the removal was really to be able to use ipip without the xfrm subsystem. This is still preserved by this patch. So now both ipip/xfrm4_tunnel depend on the new tunnel4.c which handles the arbitration between the two. The order of processing is determined by a simple integer which ensures that ipip gets processed before xfrm4_tunnel. The situation for ICMP handling is a little bit more complicated since we may not have enough information to determine who it's for. It's not a big deal at the moment since the xfrm ICMP handlers are basically no-ops. In future we can deal with this when we look at ICMP caching in general. The user-visible change to this is the removal of the TUNNEL Kconfig prompts. This makes sense because it can only be used through IPCOMP as it stands. The addition of the new modules shouldn't introduce any problems since module dependency will cause them to be loaded.

[INET]: Introduce tunnel4/tunnel6 Basically this patch moves the generic tunnel protocol stuff out of xfrm4_tunnel/xfrm6_tunnel and moves it into the new files of tunnel4.c and tunnel6 respectively. The reason for this is that the problem that Hugo uncovered is only the tip of the iceberg. The real problem is that when we removed the dependency of ipip on xfrm4_tunnel we didn't really consider the module case at all. For instance, as it is it's possible to build both ipip and xfrm4_tunnel as modules and if the latter is loaded then ipip simply won't load. After considering the alternatives I've decided that the best way out of this is to restore the dependency of ipip on the non-xfrm-specific part of xfrm4_tunnel. This is acceptable IMHO because the intention of the removal was really to be able to use ipip without the xfrm subsystem. This is still preserved by this patch. So now both ipip/xfrm4_tunnel depend on the new tunnel4.c which handles the arbitration between the two. The order of processing is determined by a simple integer which ensures that ipip gets processed before xfrm4_tunnel. The situation for ICMP handling is a little bit more complicated since we may not have enough information to determine who it's for. It's not a big deal at the moment since the xfrm ICMP handlers are basically no-ops. In future we can deal with this when we look at ICMP caching in general. The user-visible change to this is the removal of the TUNNEL Kconfig prompts. This makes sense because it can only be used through IPCOMP as it stands. The addition of the new modules shouldn't introduce any problems since module dependency will cause them to be loaded. Oh and I also turned some unnecessary pskb's in IPv6 related to this patch to skb's. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S. Miller <davem@davemloft.net>

Also, if CONFIG_IPV6=y, but CONFIG_IPV6_TUNNEL=m or CONFIG_IPV6_TUNNEL=n, the same problem happens for a different reason. This adds two new silent Kconfig symbols to work around both problems: - CONFIG_IPV6_FOU is now always set to 'm' if either CONFIG_NET_FOU=m or CONFIG_IPV6=m - CONFIG_IPV6_FOU_TUNNEL is set implicitly when IPV6_FOU is enabled and NET_FOU_IP_TUNNELS is also turned out, and it will ensure that CONFIG_IPV6_TUNNEL is also available.

fou: fix IPv6 Kconfig options The Kconfig options I added to work around broken compilation ended up screwing up things more, as I used the wrong symbol to control compilation of the file, resulting in IPv6 fou support to never be built into the kernel. Changing CONFIG_NET_FOU_IPV6_TUNNELS to CONFIG_IPV6_FOU fixes that problem, I had renamed the symbol in one location but not the other, and as the file is never being used by other kernel code, this did not lead to a build failure that I would have caught. After that fix, another issue with the same patch becomes obvious, as we 'select INET6_TUNNEL', which is related to IPV6_TUNNEL, but not the same, and this can still cause the original build failure when IPV6_TUNNEL is not built-in but IPV6_FOU is. The fix is equally trivial, we just need to select the right symbol. I have successfully build 350 randconfig kernels with this patch and verified that the driver is now being built.

ipmr,ipmr6: Define a uniform vif_device The two implementations have almost identical structures - vif_device and mif_device. As a step toward uniforming the mr_tables, eliminate the mif_device and relocate the vif_device definition into a new common header file.

ipv6: ip6mr: support multiple tables This patch adds support for multiple independant multicast routing instances, named "tables". Userspace multicast routing daemons can bind to a specific table instance by issuing a setsockopt call using a new option MRT6_TABLE. The table number is stored in the raw socket data and affects all following ip6mr setsockopt(), getsockopt() and ioctl() calls. By default, a single table (RT6_TABLE_DFLT) is created with a default routing rule pointing to it. Newly created pim6reg devices have the table number appended ("pim6regX"), with the exception of devices created in the default table, which are named just "pim6reg" for compatibility reasons. Packets are directed to a specific table instance using routing rules, similar to how regular routing rules work. Currently iif, oif and mark are supported as keys, source and destination addresses could be supported additionally. Example usage: - bind pimd/xorp/... to a specific table: uint32_t table = 123; setsockopt(fd, SOL_IPV6, MRT6_TABLE, &table, sizeof(table)); - create routing rules directing packets to the new table: # ip -6 mrule add iif eth0 lookup 123 # ip -6 mrule add oif eth0 lookup 123 Signed-off-by: Patrick McHardy <kaber@trash.net>

ipv6: sr: define core operations for seg6local lightweight tunnel This patch implements a new type of lightweight tunnel named seg6local. A seg6local lwt is defined by a type of action and a set of parameters. The action represents the operation to perform on the packets matching the lwt's route, and is not necessarily an encapsulation. The set of parameters are arguments for the processing function. Each action is defined in a struct seg6_action_desc within seg6_action_table[]. This structure contains the action, mandatory attributes, the processing function, and a static headroom size required by the action. The mandatory attributes are encoded as a bitmask field. The static headroom is set to a non-zero value when the processing function always add a constant number of bytes to the skb (e.g. the header size for encapsulations). To facilitate rtnetlink-related operations such as parsing, fill_encap, and cmp_encap, each type of action parameter is associated to three function pointers, in seg6_action_params[]. All actions defined in seg6_local.h are detailed in [1].

ipv6: sr: add core files for SR HMAC support This patch adds the necessary functions to compute and check the HMAC signature of an SR-enabled packet. Two HMAC algorithms are supported: hmac(sha1) and hmac(sha256). In order to avoid dynamic memory allocation for each HMAC computation, a per-cpu ring buffer is allocated for this purpose. A new per-interface sysctl called seg6_require_hmac is added, allowing a user-defined policy for processing HMAC-signed SR-enabled packets. A value of -1 means that the HMAC field will always be ignored. A value of 0 means that if an HMAC field is present, its validity will be enforced (the packet is dropped is the signature is incorrect). Finally, a value of 1 means that any SR-enabled packet that does not contain an HMAC signature or whose signature is incorrect will be dropped.

bpf: Add IPv6 Segment Routing helpers The BPF seg6local hook should be powerful enough to enable users to implement most of the use-cases one could think of. After some thinking, we figured out that the following actions should be possible on a SRv6 packet, requiring 3 specific helpers : - bpf_lwt_seg6_store_bytes: Modify non-sensitive fields of the SRH - bpf_lwt_seg6_adjust_srh: Allow to grow or shrink a SRH (to add/delete TLVs) - bpf_lwt_seg6_action: Apply some SRv6 network programming actions (specifically End.X, End.T, End.B6 and End.B6.Encap) The specifications of these helpers are provided in the patch (see include/uapi/linux/bpf.h). The non-sensitive fields of the SRH are the following : flags, tag and TLVs. The other fields can not be modified, to maintain the SRH integrity. Flags, tag and TLVs can easily be modified as their validity can be checked afterwards via seg6_validate_srh. It is not allowed to modify the segments directly. If one wants to add segments on the path, he should stack a new SRH using the End.B6 action via bpf_lwt_seg6_action. Growing, shrinking or editing TLVs via the helpers will flag the SRH as invalid, and it will have to be re-validated before re-entering the IPv6 layer. This flag is stored in a per-CPU buffer, along with the current header length in bytes. Storing the SRH len in bytes in the control block is mandatory when using bpf_lwt_seg6_adjust_srh. The Header Ext. Length field contains the SRH len rounded to 8 bytes (a padding TLV can be inserted to ensure the 8-bytes boundary). When adding/deleting TLVs within the BPF program, the SRH may temporary be in an invalid state where its length cannot be rounded to 8 bytes without remainder, hence the need to store the length in bytes separately. The caller of the BPF program can then ensure that the SRH's final length is valid using this value. Again, a final SRH modified by a BPF program which doesn’t respect the 8-bytes boundary will be discarded as it will be considered as invalid. Finally, a fourth helper is provided, bpf_lwt_push_encap, which is available from the LWT BPF IN hook, but not from the seg6local BPF one. This helper allows to encapsulate a Segment Routing Header (either with a new outer IPv6 header, or by inlining it directly in the existing IPv6 header) into a non-SRv6 packet. This helper is required if we want to offer the possibility to dynamically encapsulate a SRH for non-SRv6 packet, as the BPF seg6local hook only works on traffic already containing a SRH. This is the BPF equivalent of the seg6 LWT infrastructure, which achieves the same purpose but with a static SRH per route. These helpers require CONFIG_IPV6=y (and not =m).
