5 daysvsock/test: add stream TX credit bounds testMelbin K Mathew1-0/+101
Add a regression test for the TX credit bounds fix. The test verifies that a sender with a small local buffer size cannot queue excessive data even when the peer advertises a large receive buffer. The client: - Sets a small buffer size (64 KiB) - Connects to server (which advertises 2 MiB buffer) - Sends in non-blocking mode until EAGAIN - Verifies total queued data is bounded This guards against the original vulnerability where a remote peer could cause unbounded kernel memory allocation by advertising a large buffer and reading slowly.

5 daysvsock/test: fix seqpacket message bounds testStefano Garzarella1-0/+11
The test requires the sender (client) to send all messages before waking up the receiver (server). Since virtio-vsock had a bug and did not respect the size of the TX buffer, this test worked, but now that we are going to fix the bug, the test hangs because the sender would fill the TX buffer before waking up the receiver. Set the buffer size in the sender (client) as well, as we already do for the receiver (server).

6 daysselftests: net: amt: wait longer for connection before sending packetsTaehee Yoo1-2/+5
Both send_mcast4() and send_mcast6() use sleep 2 to wait for the tunnel connection between the gateway and the relay, and for the listener socket to be created in the LISTENER namespace. However, tests sometimes fail because packets are sent before the connection is fully established. Increase the waiting time to make the tests more reliable, and use wait_local_port_listen() to explicitly wait for the listener socket.

Initialize _evtfd to -1 in struct dev_ctx to prevent garbage output when running kublk in foreground mode. Without this, _evtfd is zero-initialized to 0 (stdin), and ublk_send_dev_event() writes binary data to stdin which appears as garbage on the terminal. Also fix debug message format string.

6 daysselftests/ublk: fix error handling for starting deviceMing Lei1-2/+4
Fix error handling in ublk_start_daemon() when start_dev fails: 1. Call ublk_ctrl_stop_dev() to cancel inflight uring_cmd before cleanup. Without this, the device deletion may hang waiting for I/O completion that will never happen. 2. Add fail_start label so that pthread_join() is called on the error path. This ensures proper thread cleanup when startup fails.

12 daysvsock/test: Add test for a linear and non-linear skb getting coalescedMichal Luczaj3-0/+82
Loopback transport can mangle data in rx queue when a linear skb is followed by a small MSG_ZEROCOPY packet. To exercise the logic, send out two packets: a weirdly sized one (to ensure some spare tail room in the skb) and a zerocopy one that's small enough to fit in the spare room of its predecessor. Then, wait for both to land in the rx queue, and check the data received. Faulty packets merger manifests itself by corrupting payload of the later packet.

13 daystools/testing/selftests: fix gup_longterm for unknown fsLorenzo Stoakes1-1/+1
Commit 66bce7afbaca ("selftests/mm: fix test result reporting in gup_longterm") introduced a small bug causing unknown filesystems to always result in a test failure. This is because do_test() was updated to use a common reporting path, but this case appears to have been missed. This is problematic for e.g. virtme-ng which uses an overlayfs file system, causing gup_longterm to appear to fail each time due to a test count mismatch: # Planned tests != run tests (50 != 46) # Totals: pass:24 fail:0 xfail:0 xpass:0 skip:22 error:0 The fix is to simply change the return into a break.

2026-01-13cxl: Check for invalid addresses returned from translation functions on errorsRobert Richter1-12/+18
Translation functions may return an invalid address in case of errors. If the address is not checked the further use of the invalid value will cause an address corruption. Consistently check for a valid address returned by translation functions. Use RESOURCE_SIZE_MAX to indicate an invalid address for type resource_size_t. Depending on the type either RESOURCE_SIZE_MAX or ULLONG_MAX is used to indicate an address error. Propagating an invalid address from a failed translation may cause userspace to think it has received a valid SPA, when in fact it is wrong. The CXL userspace API, using trace events, expects ULLONG_MAX to indicate a translation failure. If ULLONG_MAX is not returned immediately, subsequent calculations can transform that bad address into a different value (!ULLONG_MAX), and an invalid SPA may be returned to userspace. This can lead to incorrect diagnostics and erroneous corrective actions.

2026-01-10selftests: kvm: replace numbered sync points with actionsPaolo Bonzini1-45/+43
Rework the guest=>host syncs in the AMX test to use named actions instead of arbitrary, incrementing numbers. The "stage" of the test has no real meaning, what matters is what action the test wants the host to perform. The incrementing numbers are somewhat helpful for triaging failures, but fully debugging failures almost always requires a much deeper dive into the test (and KVM). Using named actions not only makes it easier to extend the test without having to shift all sync point numbers, it makes the code easier to read.
