ITS-vulnerable retpoline sites are runtime patched to point to newly +added ITS-safe thunks. These safe thunks consists of indirect branch in the +second half of the cacheline. Not all retpoline sites are patched to thunks, if +a retpoline site is evaluated to be ITS-safe, it is replaced with an inline +indirect branch. + +Dynamic thunks +~~~~~~~~~~~~~~ +From a dynamically allocated pool of safe-thunks, each vulnerable site is +replaced with a new thunk, such that they get a unique address. This could +improve the branch prediction accuracy. Also, it is a defense-in-depth measure +against aliasing. + +Note, for simplicity, indirect branches in eBPF programs are always replaced +with a jump to a static thunk in __x86_indirect_its_thunk_array. If required, +in future this can be changed to use dynamic thunks. + +All vulnerable RETs are replaced with a static thunk, they do not use dynamic +thunks. This is because RETs get their prediction from RSB mostly that does not +depend on source address. RETs that underflow RSB may benefit from dynamic +thunks. But, RETs significantly outnumber indirect branches, and any benefit +from a unique source address could be outweighed by the increased icache +footprint and iTLB pressure. + +Retpoline +~~~~~~~~~ +Retpoline sequence also mitigates ITS-unsafe indirect branches. For this +reason, when retpoline is enabled, ITS mitigation only relocates the RETs to +safe thunks. Unless user requested the RSB-stuffing mitigation. + +RSB Stuffing +~~~~~~~~~~~~ +RSB-stuffing via Call Depth Tracking is a mitigation for Retbleed RSB-underflow +attacks. And it also mitigates RETs that are vulnerable to ITS. + +Mitigation in guests +^^^^^^^^^^^^^^^^^^^^ +All guests deploy ITS mitigation by default, irrespective of eIBRS enumeration +and Family/Model of the guest. This is because eIBRS feature could be hidden +from a guest. One exception to this is when a guest enumerates BHI_DIS_S, which +indicates that the guest is running on an unaffected host. + +To prevent guests from unnecessarily deploying the mitigation on unaffected +platforms, Intel has defined ITS_NO bit(62) in MSR IA32_ARCH_CAPABILITIES. When +a guest sees this bit set, it should not enumerate the ITS bug. Note, this bit +is not set by any hardware, but is **intended for VMMs to synthesize** it for +guests as per the host's affected status. + +Mitigation options +^^^^^^^^^^^^^^^^^^ +The ITS mitigation can be controlled using the "indirect_target_selection" +kernel parameter. The available options are: + + ======== =================================================================== + on (default) Deploy the "Aligned branch/return thunks" mitigation. + If spectre_v2 mitigation enables retpoline, aligned-thunks are only + deployed for the affected RET instructions.

SPDX-License-Identifier: GPL-2.0 + +================================== +Tracefs ring-buffer memory mapping +================================== + +:Author: Vincent Donnefort + +Overview +======== +Tracefs ring-buffer memory map provides an efficient method to stream data +as no memory copy is necessary. The application mapping the ring-buffer becomes +then a consumer for that ring-buffer, in a similar fashion to trace_pipe. + +Memory mapping setup +==================== +The mapping works with a mmap() of the trace_pipe_raw interface. + +The first system page of the mapping contains ring-buffer statistics and +description. It is referred to as the meta-page. One of the most important +fields of the meta-page is the reader. It contains the sub-buffer ID which can +be safely read by the mapper (see ring-buffer-design.rst). + +The meta-page is followed by all the sub-buffers, ordered by ascending ID. It is +therefore effortless to know where the reader starts in the mapping: + +.. code-block:: c + + reader_id = meta->reader->id; + reader_offset = meta->meta_page_size + reader_id * meta->subbuf_size; + +When the application is done with the current reader, it can get a new one using +the trace_pipe_raw ioctl() TRACE_MMAP_IOCTL_GET_READER. This ioctl also updates +the meta-page fields. + +Limitations +=========== +When a mapping is in place on a Tracefs ring-buffer, it is not possible to +either resize it (either by increasing the entire size of the ring-buffer or +each subbuf). It is also not possible to use snapshot and causes splice to copy +the ring buffer data instead of using the copyless swap from the ring buffer. + +Concurrent readers (either another application mapping that ring-buffer or the +kernel with trace_pipe) are allowed but not recommended.

+================== + +:Author: Andrea Righi + +Overview +======== + +Each Ubuntu kernel needs to maintain its own .config for each supported +architecture and each flavour. + +Every time a new patch is applied or a kernel is rebased on top of a new +one, we need to update the .config's accordingly (config options can be +added, removed and also renamed). + +So, we need to make sure that some critical config options are always +matching the desired value in order to have a functional kernel. + +State of the art +================ + +At the moment configs are maintained as a set of Kconfig chunks (inside +`debian./config/`): a global one, plus per-arch / per-flavour +chunks. + +In addition to that, we need to maintain also a file called +'annotations'; the purpose of this file is to make sure that some +critical config options are not silently removed or changed when the +real .config is re-generated (for example after a rebase or after +applying a new set of patches). + +The main problem with this approach is that, often, we have duplicate +information that is stored both in the Kconfig chunks *and* in the +annotations files and, at the same time, the whole .config's information +is distributed between Kconfig chunks and annotations, making it hard to +maintain, review and manage in general. + +Proposed solution +================= + +The proposed solution is to store all the config information into the +"annotations" format and get rid of the config chunks (basically the +real .config's can be produced "compiling" annotations). + +Implementation +============== + +To help the management of the annotations an helper script is provided +(`debian/scripts/misc/annotations`): + +``` +usage: annotations [-h] [--version] [--file FILE] [--arch ARCH] [--flavour FLAVOUR] [--config CONFIG] + (--query | --export | --import FILE | --update FILE | --check FILE) + +Manage Ubuntu kernel .config and annotations + +options: + -h, --help show this help message and exit + --version, -v show program's version number and exit + --file FILE, -f FILE Pass annotations or .config file to be parsed + --arch ARCH, -a ARCH Select architecture + --flavour FLAVOUR, -l FLAVOUR + Select flavour (default is "generic") + --config CONFIG, -c CONFIG + Select a specific config option + +Action: + --query, -q Query annotations + --export, -e Convert annotations to .config format + --import FILE, -i FILE + Import a full .config for a specific arch and flavour into annotations + --update FILE, -u FILE + Import a partial .config into annotations (only resync configs specified in FILE) + --check FILE, -k FILE + Validate kernel .config with annotations +``` + +This script allows to query config settings (per arch/flavour/config), +export them into the Kconfig format (generating the real .config files) +and check if the final .config matches the rules defined in the +annotations. + +Examples (annotations is defined as an alias to `debian/scripts/annotations`): + + - Show settings for `CONFIG_DEBUG_INFO_BTF` for master kernel across all the + supported architectures and flavours: + +``` +$ annotations --query --config CONFIG_DEBUG_INFO_BTF +{ + "policy": { + "amd64": "y", + "arm64": "y", + "armhf": "n", + "ppc64el": "y", + "riscv64": "y", + "s390x": "y" + }, + "note": "'Needs newer pahole for armhf'" +} +``` + + - Dump kernel .config for arm64 and flavour generic-64k: + +``` +$ annotations --arch arm64 --flavour generic-64k --export +CONFIG_DEBUG_FS=y +CONFIG_DEBUG_KERNEL=y +CONFIG_COMPAT=y +... +``` + + - Update annotations file with a new kernel .config for amd64 flavour + generic: + +``` +$ annotations --arch amd64 --flavour generic --import build/.config +``` + +Moreover, an additional kernelconfig commands are provided +(via debian/rules targets): + - `migrateconfigs`: automatically merge all the previous configs into + annotations (local changes still need to be committed) + +Annotations headers +=================== + +The main annotations file should contain a header to define the architectures +and flavours that are supported. + +Here is the format of the header for the generic kernel: +``` +# Menu: HEADER +# FORMAT: 4 +# ARCH: amd64 arm64 armhf ppc64el riscv64 s390x +# FLAVOUR: amd64-generic arm64-generic arm64-generic-64k armhf-generic armhf-generic-lpae ppc64el-generic riscv64-generic s390x-generic + +``` + +Example header of a derivative (linux-aws): +``` +# Menu: HEADER +# FORMAT: 4 +# ARCH: amd64 arm64 +# FLAVOUR: amd64-aws arm64-aws +# FLAVOUR_DEP: {'amd64-aws': 'amd64-generic', 'arm64-aws': 'arm64-generic'} + +include "../../debian.master/config/annotations" + +# Below you can define only the specific linux-aws configs that differ from linux generic + +``` + +Pros and Cons +============= + + Pros: + - avoid duplicate information in .config's and annotations + - allow to easily define groups of config settings (for a specific + environment or feature, such as annotations.clouds, annotations.ubuntu, + annotations.snapd, etc.) + - config options are more accessible, easy to change and review + - we can easily document how config options are managed (and external + contributors won't be discouraged anymore when they need to to change a + config option) + + Cons: + - potential regressions: the new tool/scripts can have potential bugs, + so we could experience regressions due to some missed config changes + - kernel team need to understand the new process (even if everything + is transparent, kernel cranking process is the same, there might be + corner cases that need to be addressed and resolved manually) + +TODO +==== + + - Migrate all flavour and arch definitions into annotations (rather + than having this information defined in multiple places inside + debian/scripts); right now this information is "partially" migrated, + meaning that we need to define arches and flavours in the headers + section of annotations (so that the annotations tool can figure out + the list of supported arches and flavours), but arches and flavours + are still defined elsewhere, ideally we would like to have arches and + flavours defined only in one place: annotations. --- linux-6.8.0.orig/debian.master/config/annotations +++ linux-6.8.0/debian.master/config/annotations @@ -0,0 +1,15575 @@ +# Menu: HEADER +# FORMAT: 4 +# ARCH: amd64 arm64

This transformation is + * described in detail further below. + * + * Using netmasks for the overlay and underlay other than /8 and /16, as + * shown above, can yield larger (or smaller) overlay subnets, with the + * trade-off of allowing fewer (or more) underlay hosts to participate. + * + * The size of each overlay network subnet is defined by the total of the + * network mask of the overlay plus the size of host portion of the + * underlay network. In the above example, /8 + /16 = /24. + * + * E.g., consider underlay host 10.99.238.5/20 and overlay 99.0.0.0/8. In + * this case, the network portion of the underlay is 10.99.224.0/20, and + * the host portion is 0.0.14.5 (12 bits). To determine the overlay + * network subnet, the 12 bits of host portion are left shifted 12 bits + * (/20 - /8) and ORed with the overlay subnet prefix. This yields an + * overlay subnet of 99.224.80/20, composed of 8 bits overlay, followed by + * 12 bits underlay. This yields 12 bits in the overlay network portion, + * allowing for 4094 addresses in each overlay network subnet. The + * trade-off is that fewer hosts may participate in the underlay network, + * as its host address size has shrunk from 16 bits (65534 addresses) in + * the first example to 12 bits (4094 addresses) here. + * + * For fewer hosts per overlay subnet (permitting a larger number of + * underlay hosts to participate), the underlay netmask may be made + * smaller. + * + * E.g., underlay host 10.111.1.2/12 (network 10.96.0.0/12, host portion + * is 0.15.1.2, 20 bits) with an overlay of 33.0.0.0/8 would left shift + * the 20 bits of host by 4 (so that it's highest order bit is adjacent to + * the lowest order bit of the /8 overlay). This yields an overlay subnet + * of 33.240.16.32/28 (8 bits overlay, 20 bits from the host portion of + * the underlay). This provides more addresses for the underlay network + * (approximately 2^20), but each host's segment of the overlay provides + * only 4 bits of addresses (14 usable). + * + * It is also possible to adjust the overlay subnet. + * + * For an overlay of 240.0.0.0/5 and underlay of 10.88.0.0/20, consider + * underlay host 10.88.129.2; the 12 bits of host, 0.0.1.2, are left + * shifted 15 bits (/20 - /5), yielding an overlay network of + * 240.129.0.0/17. An underlay host of 10.88.244.215 would yield an + * overlay network of 242.107.128.0/17. + * + * For an overlay of 100.64.0.0/10 and underlay of 10.224.220.0/24, for + * underlay host 10.224.220.10, the underlay host portion (.10) is left + * shifted 14 bits, yielding an overlay network subnet of 100.66.128.0/18. + * This would permit 254 addresses on the underlay, with each overlay + * segment providing approximately 2^14 - 2 addresses (16382). + * + * For packets being encapsulated, the overlay network destination IP + * address is deconstructed into its overlay and underlay-derived + * portions. The underlay portion (determined by the overlay mask and + * overlay subnet mask) is right shifted according to the size of the + * underlay network mask. This value is then ORed with the network + * portion of the underlay network to produce the underlay network + * destination for the encapsulated datagram. + * + * For example, using the initial example of underlay 10.88.3.4/16 and + * overlay 99.0.0.0/8, with underlay host 10.88.3.4/16 providing overlay + * subnet 99.3.4.0/24 with specfic host 99.3.4.5. A datagram from + * 99.3.4.5 to 99.6.7.8 would first have the underlay host derived portion + * of the address extracted. This is a number of bits equal to underlay + * network host portion. In the destination address, the highest order of + * these bits is one bit lower than the lowest order bit from the overlay + * network mask. + * + * Using the sample value, 99.6.7.8, the overlay mask is /8, and the + * underlay mask is /16 (leaving 16 bits for the host portion). The bits + * to be shifted are the middle two octets, 0.6.7.0, as this is 99.6.7.8 + * ANDed with the mask 0x00ffff00 (which is 16 bits, the highest order of + * which is 1 bit lower than the lowest order overlay address bit). + * + * These octets, 0.6.7.0, are then right shifted 8 bits, yielding 0.0.6.7. + * This value is then ORed with the underlay network portion, + * 10.88.0.0/16, providing 10.88.6.7 as the final underlay destination for + * the encapuslated datagram. + * + * Another transform using the final example: overlay 100.64.0.0/10 and + * underlay 10.224.220.0/24.

This is right shifted 14 + * (32 - 10 - (32 - 24), i.e., the number of bits between the overlay + * network portion and the underlay host portion) bits, yielding 0.0.0.11. + * This is ORed with the underlay network portion, 10.224.220.0/24, giving + * the underlay destination of 10.224.220.11 for overlay destination + * 100.66.200.5. + */ +static int ipip_build_fan_iphdr(struct ip_tunnel *tunnel, struct sk_buff *skb, struct iphdr *iph) +{ + struct ip_fan_map *f_map;
