2020-12-03bpf: Remove hard-coded btf_vmlinux assumption from BPF verifierAndrii Nakryiko
Remove a permeating assumption thoughout BPF verifier of vmlinux BTF. Instead, wherever BTF type IDs are involved, also track the instance of struct btf that goes along with the type ID. This allows to gradually add support for kernel module BTFs and using/tracking module types across BPF helper calls and registers. This patch also renames btf_id() function to btf_obj_id() to minimize naming clash with using btf_id to denote BTF *type* ID, rather than BTF *object*'s ID. Also, altough btf_vmlinux can't get destructed and thus doesn't need refcounting, module BTFs need that, so apply BTF refcounting universally when BPF program is using BTF-powered attachment (tp_btf, fentry/fexit, etc). This makes for simpler clean up code. Now that BTF type ID is not enough to uniquely identify a BTF type, extend BPF trampoline key to include BTF object ID. To differentiate that from target program BPF ID, set 31st bit of type ID. BTF type IDs (at least currently) are not allowed to take full 32 bits, so there is no danger of confusing that bit with a valid BTF type ID.

2020-12-03mptcp: emit tcp reset when a join request failsFlorian Westphal
RFC 8684 says: If the token is unknown or the host wants to refuse subflow establishment (for example, due to a limit on the number of subflows it will permit), the receiver will send back a reset (RST) signal, analogous to an unknown port in TCP, containing an MP_TCPRST option (Section 3.6) with an "MPTCP specific error" reason code. mptcp-next doesn't support MP_TCPRST yet, this can be added in another change.

2020-12-03tcp: merge 'init_req' and 'route_req' functionsFlorian Westphal
The Multipath-TCP standard (RFC 8684) says that an MPTCP host should send a TCP reset if the token in a MP_JOIN request is unknown. At this time we don't do this, the 3whs completes and the 'new subflow' is reset afterwards. There are two ways to allow MPTCP to send the reset. 1. override 'send_synack' callback and emit the rst from there. The drawback is that the request socket gets inserted into the listeners queue just to get removed again right away. 2. Send the reset from the 'route_req' function instead. This avoids the 'add&remove request socket', but route_req lacks the skb that is required to send the TCP reset. Instead of just adding the skb to that function for MPTCP sake alone, Paolo suggested to merge init_req and route_req functions. This saves one indirection from syn processing path and provides the skb to the merged function at the same time. 'send reset on unknown mptcp join token' is added in next patch.

2020-12-02net/x25: prevent a couple of overflowsDan Carpenter
The .x25_addr[] address comes from the user and is not necessarily NUL terminated. This leads to a couple problems. The first problem is that the strlen() in x25_bind() can read beyond the end of the buffer. The second problem is more subtle and could result in memory corruption. The call tree is: x25_connect() --> x25_write_internal() --> x25_addr_aton() The .x25_addr[] buffers are copied to the "addresses" buffer from x25_write_internal() so it will lead to stack corruption. Verify that the strings are NUL terminated and return -EINVAL if they are not.

rpc_prepare_reply_pages() currently expects the 'hdrsize' argument to contain the length of the data that we expect to want placed in the head kvec plus a count of 1 word of padding that is placed after the page data. This is very confusing when trying to read the code, and sometimes leads to callers adding an arbitrary value of '1' just in order to satisfy the requirement (whether or not the page data actually needs such padding). This patch aims to clarify the code by changing the 'hdrsize' argument to remove that 1 word of padding. This means we need to subtract the padding from all the existing callers.
