2023-10-20tracing/kprobes: Return EADDRNOTAVAIL when func matches several symbolsFrancis Laniel
When a kprobe is attached to a function that's name is not unique (is static and shares the name with other functions in the kernel), the kprobe is attached to the first function it finds. This is a bug as the function that it is attaching to is not necessarily the one that the user wants to attach to. Instead of blindly picking a function to attach to what is ambiguous, error with EADDRNOTAVAIL to let the user know that this function is not unique, and that the user must use another unique function with an address offset to get to the function they want to attach to.

2023-10-19tools build: Fix llvm feature detection, still used by bpftoolArnaldo Carvalho de Melo
When removing the BPF event for perf a feature test that checks if the llvm devel files are availabe was removed but that is also used by bpftool. bpftool uses it to decide what kind of disassembly it will use: llvm or binutils based. Removing the tools/build/feature/test-llvm.cpp file made bpftool to always fallback to binutils disassembly, even with the llvm devel files installed, fix it by restoring just that small test-llvm.cpp test file.

2023-10-19iomap: fix short copy in iomap_write_iter()Jan Stancek
Starting with commit 5d8edfb900d5 ("iomap: Copy larger chunks from userspace"), iomap_write_iter() can get into endless loop. This can be reproduced with LTP writev07 which uses partially valid iovecs: struct iovec wr_iovec[] = { { buffer, 64 }, { bad_addr, 64 }, { buffer + 64, 64 }, { buffer + 64 * 2, 64 }, }; commit bc1bb416bbb9 ("generic_perform_write()/iomap_write_actor(): saner logics for short copy") previously introduced the logic, which made short copy retry in next iteration with amount of "bytes" it managed to copy: if (unlikely(status == 0)) { /* * A short copy made iomap_write_end() reject the * thing entirely. Might be memory poisoning * halfway through, might be a race with munmap, * might be severe memory pressure. */ if (copied) bytes = copied; However, since 5d8edfb900d5 "bytes" is no longer carried into next iteration, because it is now always initialized at the beginning of the loop. And for iov_iter_count < PAGE_SIZE, "bytes" ends up with same value as previous iteration, making the loop retry same copy over and over, which leads to writev07 testcase hanging. Make next iteration retry with amount of bytes we managed to copy.

This reverts commit 108a36d07c01edbc5942d27c92494d1c6e4d45a0. It was reported that this fix breaks the possibility to remove existing WoL flags. For example: ~$ ethtool lan2 ... Supports Wake-on: pg Wake-on: d ... ~$ ethtool -s lan2 wol gp ~$ ethtool lan2 ... Wake-on: pg ... ~$ ethtool -s lan2 wol d ~$ ethtool lan2 ... Wake-on: pg ... This worked correctly before this commit because we were always updating a zero bitmap (since commit 6699170376ab ("ethtool: fix application of verbose no_mask bitset"), that is) so that the rest was left zero naturally. But now the 1->0 change (old_val is true, bit not present in netlink nest) no longer works.

2023-10-19mptcp: avoid sending RST when closing the initial subflowGeliang Tang
When closing the first subflow, the MPTCP protocol unconditionally calls tcp_disconnect(), which in turn generates a reset if the subflow is established. That is unexpected and different from what MPTCP does with MPJ subflows, where resets are generated only on FASTCLOSE and other edge scenarios. We can't reuse for the first subflow the same code in place for MPJ subflows, as MPTCP clean them up completely via a tcp_close() call, while must keep the first subflow socket alive for later re-usage, due to implementation constraints. This patch adds a new helper __mptcp_subflow_disconnect() that encapsulates, a logic similar to tcp_close, issuing a reset only when the MPTCP_CF_FASTCLOSE flag is set, and performing a clean shutdown otherwise.

2023-10-19tcp: check mptcp-level constraints for backlog coalescingPaolo Abeni
The MPTCP protocol can acquire the subflow-level socket lock and cause the tcp backlog usage. When inserting new skbs into the backlog, the stack will try to coalesce them. Currently, we have no check in place to ensure that such coalescing will respect the MPTCP-level DSS, and that may cause data stream corruption, as reported by Christoph. Address the issue by adding the relevant admission check for coalescing in tcp_add_backlog(). Note the issue is not easy to reproduce, as the MPTCP protocol tries hard to avoid acquiring the subflow-level socket lock.
