bpf: Derive source IP addr via bpf_*_fib_lookup()

2024-03-01T12:35:04+00:00

commit dab4e1f06cabb6834de14264394ccab197007302 upstream. Extend the bpf_fib_lookup() helper by making it to return the source IPv4/IPv6 address if the BPF_FIB_LOOKUP_SRC flag is set. For example, the following snippet can be used to derive the desired source IP address: struct bpf_fib_lookup p = { .ipv4_dst = ip4->daddr }; ret = bpf_skb_fib_lookup(skb, p, sizeof(p), BPF_FIB_LOOKUP_SRC | BPF_FIB_LOOKUP_SKIP_NEIGH); if (ret != BPF_FIB_LKUP_RET_SUCCESS) return TC_ACT_SHOT; /* the p.ipv4_src now contains the source address */ The inability to derive the proper source address may cause malfunctions in BPF-based dataplanes for hosts containing netdevs with more than one routable IP address or for multi-homed hosts. For example, Cilium implements packet masquerading in BPF. If an egressing netdev to which the Cilium's BPF prog is attached has multiple IP addresses, then only one [hardcoded] IP address can be used for masquerading. This breaks connectivity if any other IP address should have been selected instead, for example, when a public and private addresses are attached to the same egress interface. The change was tested with Cilium [1]. Nikolay Aleksandrov helped to figure out the IPv6 addr selection.

btrfs: defrag: reject unknown flags of btrfs_ioctl_defrag_range_args

2024-02-01T00:19:06+00:00

commit 173431b274a9a54fc10b273b46e67f46bcf62d2e upstream. Add extra sanity check for btrfs_ioctl_defrag_range_args::flags. This is not really to enhance fuzzing tests, but as a preparation for future expansion on btrfs_ioctl_defrag_range_args. In the future we're going to add new members, allowing more fine tuning for btrfs defrag. Without the -ENONOTSUPP error, there would be no way to detect if the kernel supports those new defrag features.

bpf: Add crosstask check to __bpf_get_stack

2024-01-25T23:35:19+00:00

[ Upstream commit b8e3a87a627b575896e448021e5c2f8a3bc19931 ] Currently get_perf_callchain only supports user stack walking for the current task. Passing the correct *crosstask* param will return 0 frames if the task passed to __bpf_get_stack isn't the current one instead of a single incorrect frame/address. This change passes the correct *crosstask* param but also does a preemptive check in __bpf_get_stack if the task is current and returns -EOPNOTSUPP if it is not. This issue was found using bpf_get_task_stack inside a BPF iterator ("iter/task"), which iterates over all tasks. bpf_get_task_stack works fine for fetching kernel stacks but because get_perf_callchain relies on the caller to know if the requested *task* is the current one (via *crosstask*) it was failing in a confusing way. It might be possible to get user stacks for all tasks utilizing something like access_process_vm but that requires the bpf program calling bpf_get_task_stack to be sleepable and would therefore be a breaking change.

fuse: Rename DIRECT_IO_RELAX to DIRECT_IO_ALLOW_MMAP

2023-12-20T16:01:51+00:00

commit c55e0a55b165202f18cbc4a20650d2e1becd5507 upstream. Although DIRECT_IO_RELAX's initial usage is to allow shared mmap, its description indicates a purpose of reducing memory footprint. This may imply that it could be further used to relax other DIRECT_IO operations in the future. Replace it with a flag DIRECT_IO_ALLOW_MMAP which does only one thing, allow shared mmap of DIRECT_IO files while still bypassing the cache on regular reads and writes. [Miklos] Also Keep DIRECT_IO_RELAX definition for backward compatibility.
