Some comparisons could not be completed because a pull request conflicts with the base branch. Review these shared files manually before concluding that there is no overlap.

The overlap table lists no shared export and no shared new file for any of these pull requests, so none of them implements this behaviour: the co-touches are textual. The change is in the Issue #8681 was worked on by PR #8682, which was closed on 2026-10-21 after a review that asked for the IPv6 case. This branch covers that case, and adds a never-associated socket and a socket bound to an explicit port. It does not depend on any open pull request. |

Second platform, since upstream merges pull requests that report both. Ubuntu 24.04.3 (GCC 13.3.0, CMake 3.28.3, Ninja 1.11.1, WSL2): The change only affects the address A contributor's independent run on a second machine appears to help a pull request along, so this is offered the same way. |

…tion is dissolved FreeBSD 11.4's udp_disconnect resets the local address to the wildcard address and keeps the port. The host socket keeps the address it was bound to, so getsockname reported 127.0.0.1 on Windows and on Linux for a socket bound to an explicit port. The socket now remembers that its association was dissolved and getsockname reports the wildcard address for IPv4 and IPv6 until the next bind or connect.

I reviewed the prior resolution of this same behavior in #8682. After the author measured that an explicitly bound Winsock socket remains bound to 127.0.0.1 and sendto to a LAN address still fails after the disconnect, the collaborator closed that PR and asked for a documentation-only debt update unless a title requiring the behavior is identified. The author said no such title was known. See the maintainer resolution and the author's measurement and agreement.
This PR reintroduces the same mismatch: Disconnect sets localAddressCleared, and getsockname zeros the reported address, while the host socket remains bound to its original address. The new tests assert the reported name but do not check that send/receive behavior now matches a wildcard-bound socket. The PR names no title (Unblocks: none) and explicitly says the host socket is unchanged. The IPv6 coverage improves the test matrix but does not resolve this semantic blocker. Please convert this to the docs-only debt update requested in #8682, or provide a specific title and measured call sequence that requires this behavior together with an implementation that keeps the host socket semantics consistent. Keep #8681 open unless the full behavior is resolved; Fixes #8681 is not supported by the current code.
There are also required queue updates:
- Current
mainisd6732b51a64f; this head is 91 commits behind it. Please rebase and rerun the conventions and overlap checks. - The refreshed overlap scan finds active UDP/debt overlaps with #8344, #8499, #8921, #9105, #9108 and #9169, plus #7511/#8448 in the debt entry. It could not compare the
GuestUdp.cppchanges with #6044. Please coordinate the affected hunks and update the merge-order/Depends onchecklist after rebase. In particular, #8921 is the existing docs-only treatment requested by the #8682 resolution.
I configured and built guest_udp_tests from this head successfully. guest_udp could not execute on this host: startup aborts because the CPU lacks LZCNT, BMI1/2, MOVBE, AVX2 and FMA. I did not count that as a test pass. tools/check_conventions.py --base upstream/main passes, as does git diff --check. The reported Windows and WSL2 runs are useful; only Conventions and PR labels are present and green in this head's hosted checks, with no hosted build/test result shown.

The change is already integrated on the agent/integration line as c681bcf, with the same three files (core/libs/prx/libkernel/Socket/src/Udp.cpp, core/libs/tests/GuestUdp.cpp, docs/dev/debt/libkernel.md). Closing this to free the single open pull request the account limit allows, so #9649 can carry the libSceIcu, libSceNpCommon and libSceXml work. |

What
getsocknameon a UDP socket reported the old local address after the association was dissolved.connect(s, AF_UNSPEC)resets the local address to the wildcard address on the console, keeping the port; AnyPS5 kept reporting the address the socket was bound to.FreeBSD 11.4's
udp_disconnect(sys/netinet/udp_usrreq.c) doesinp->inp_laddr.s_addr = INADDR_ANY;and leavesinp->inp_lportuntouched, so the local address becomes the wildcard and the port is kept, on every host.No portable host call produces that. Linux's
connect(AF_UNSPEC)resets the local address only when the socket was not explicitly bound (SOCK_BINDADDR_LOCK), and a bound socket cannot be bound again (EBUSY); Windows keeps the address unconditionally. The socket now records that its association was dissolved andgetsocknamereports the wildcard address (IPv4 and IPv6) until the nextbindorconnect.The host socket keeps the address it was bound to, so it still receives only what that address delivers, where the console's socket, whose local address is the wildcard address, receives on any address of its port. That difference stays recorded in the technical debt.
