From 642fa98976d75c78a5e5af39c185d59f8268cb1f Mon Sep 17 00:00:00 2001 From: Matthew Heon Date: Mon, 11 Sep 2023 13:41:15 -0400 Subject: [PATCH 1/3] Initial addition of 9p code to Podman This includes two new hidden commands: a 9p server, `podman machine server9p`, and a 9p client, `podman machine client9p` with `server9p` currently only configured to run on Windows and serve 9p via HyperV vsock, and `client9p` only configured to run on Linux. The server is run by `podman machine start` and has the same lifespan as gvproxy (waits for the gvproxy PID to die before shutting down). The client is run inside the VM, also by `podman machine start`, and mounts uses kernel 9p mount code to complete the mount. It's unfortunately not possible to use mount directly without the wrapper; we need to set up the vsock and pass it to mount as an FD. In theory this can be generalized so that the server can run anywhere and over almost any transport, but I haven't done this here as I don't think we have a usecase other than HyperV right now. [NO NEW TESTS NEEDED] This requires changes to Podman in the VM, so we need to wait until a build with this lands in FCOS to test.

However, it's been repurposed to other areas where running +user code in-kernel is needed. For example, Linux's seccomp uses BPF +to apply security policies to system calls. For simplicity, this +documentation refers only to packets, but other uses of BPF have their +own data payloads. + +BPF programs run in a restricted virtual machine. It has almost no +access to kernel functions, and while conditional branches are +allowed, they can only jump forwards, to guarantee that there are no +infinite loops. + +# The virtual machine + +The BPF VM is an accumulator machine. Its main register, called +register A, is an implicit source and destination in all arithmetic +and logic operations. The machine also has 16 scratch registers for +temporary storage, and an indirection register (register X) for +indirect memory access. All registers are 32 bits wide. + +Each run of a BPF program is given one packet, which is placed in the +VM's read-only "main memory". LoadAbsolute and LoadIndirect +instructions can fetch up to 32 bits at a time into register A for +examination. + +The goal of a BPF program is to produce and return a verdict (uint32), +which tells the kernel what to do with the packet. In the context of +packet filtering, the returned value is the number of bytes of the +packet to forward to userspace, or 0 to ignore the packet. Other +contexts like seccomp define their own return values. + +In order to simplify programs, attempts to read past the end of the +packet terminate the program execution with a verdict of 0 (ignore +packet). This means that the vast majority of BPF programs don't need +to do any explicit bounds checking. + +In addition to the bytes of the packet, some BPF programs have access +to extensions, which are essentially calls to kernel utility +functions. Currently, the only extensions supported by this package +are the Linux packet filter extensions. + +# Examples + +This packet filter selects all ARP packets. + + bpf.Assemble([]bpf.Instruction{ + // Load "EtherType" field from the ethernet header. + bpf.LoadAbsolute{Off: 12, Size: 2}, + // Skip over the next instruction if EtherType is not ARP. + bpf.JumpIf{Cond: bpf.JumpNotEqual, Val: 0x0806, SkipTrue: 1}, + // Verdict is "send up to 4k of the packet to userspace." + bpf.RetConstant{Val: 4096}, + // Verdict is "ignore packet." + bpf.RetConstant{Val: 0}, + }) + +This packet filter captures a random 1% sample of traffic. + + bpf.Assemble([]bpf.Instruction{ + // Get a 32-bit random number from the Linux kernel. + bpf.LoadExtension{Num: bpf.ExtRand}, + // 1% dice roll? + bpf.JumpIf{Cond: bpf.JumpLessThan, Val: 2^32/100, SkipFalse: 1}, + // Capture. + bpf.RetConstant{Val: 4096}, + // Ignore. + bpf.RetConstant{Val: 0}, + }) +*/ +package bpf // import "golang.org/x/net/bpf" diff --git a/vendor/golang.org/x/net/bpf/instructions.go b/vendor/golang.org/x/net/bpf/instructions.go new file mode 100644 index 0000000000..3cffcaa014 --- /dev/null +++ b/vendor/golang.org/x/net/bpf/instructions.go @@ -0,0 +1,726 @@ +// Copyright 2016 The Go Authors.

Unlike our previous approach on Windows, this one should actually work.

Distribution of Source Form + + All distribution of Covered Software in Source Code Form, including any + Modifications that You create or to which You contribute, must be under + the terms of this License. You must inform recipients that the Source + Code Form of the Covered Software is governed by the terms of this + License, and how they can obtain a copy of this License. You may not + attempt to alter or restrict the recipients' rights in the Source Code + Form. + +3.2. Distribution of Executable Form + + If You distribute Covered Software in Executable Form then: + + a. such Covered Software must also be made available in Source Code Form, + as described in Section 3.1, and You must inform recipients of the + Executable Form how they can obtain a copy of such Source Code Form by + reasonable means in a timely manner, at a charge no more than the cost + of distribution to the recipient; and + + b. You may distribute such Executable Form under the terms of this + License, or sublicense it under different terms, provided that the + license for the Executable Form does not attempt to limit or alter the + recipients' rights in the Source Code Form under this License. + +3.3. Distribution of a Larger Work + + You may create and distribute a Larger Work under terms of Your choice, + provided that You also comply with the requirements of this License for + the Covered Software. If the Larger Work is a combination of Covered + Software with a work governed by one or more Secondary Licenses, and the + Covered Software is not Incompatible With Secondary Licenses, this + License permits You to additionally distribute such Covered Software + under the terms of such Secondary License(s), so that the recipient of + the Larger Work may, at their option, further distribute the Covered + Software under the terms of either this License or such Secondary + License(s). + +3.4. Notices + + You may not remove or alter the substance of any license notices + (including copyright notices, patent notices, disclaimers of warranty, or + limitations of liability) contained within the Source Code Form of the + Covered Software, except that You may alter any license notices to the + extent required to remedy known factual inaccuracies. + +3.5. Application of Additional Terms + + You may choose to offer, and to charge a fee for, warranty, support, + indemnity or liability obligations to one or more recipients of Covered + Software. However, You may do so only on Your own behalf, and not on + behalf of any Contributor. You must make it absolutely clear that any + such warranty, support, indemnity, or liability obligation is offered by + You alone, and You hereby agree to indemnify every Contributor for any + liability incurred by such Contributor as a result of warranty, support, + indemnity or liability terms You offer. You may include additional + disclaimers of warranty and limitations of liability specific to any + jurisdiction. + +4. Inability to Comply Due to Statute or Regulation + + If it is impossible for You to comply with any of the terms of this License + with respect to some or all of the Covered Software due to statute, + judicial order, or regulation then You must: (a) comply with the terms of + this License to the maximum extent possible; and (b) describe the + limitations and the code they affect.

Moreover, Your grants from a particular Contributor are + reinstated on an ongoing basis if such Contributor notifies You of the + non-compliance by some reasonable means, this is the first time You have + received notice of non-compliance with this License from such + Contributor, and You become compliant prior to 30 days after Your receipt + of the notice. + +5.2.

This limitation of liability + shall not apply to liability for death or personal injury resulting from + such party's negligence to the extent applicable law prohibits such + limitation. Some jurisdictions do not allow the exclusion or limitation of + incidental or consequential damages, so this exclusion and limitation may + not apply to You. + +8. Litigation + + Any litigation relating to this License may be brought only in the courts + of a jurisdiction where the defendant maintains its principal place of + business and such litigation shall be governed by laws of that + jurisdiction, without reference to its conflict-of-law provisions. Nothing + in this Section shall prevent a party's ability to bring cross-claims or + counter-claims. + +9. Miscellaneous + + This License represents the complete agreement concerning the subject + matter hereof. If any provision of this License is held to be + unenforceable, such provision shall be reformed only to the extent + necessary to make it enforceable. Any law or regulation which provides that + the language of a contract shall be construed against the drafter shall not + be used to construe this License against a Contributor. + + +10.
