* [3.9] gh-119461: Fix ThreadedVSOCKSocketStreamTest (GH-129171) (GH-129440) ↵Miss Islington (bot)2025-02-191-5/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | (#130075) Fix ThreadedVSOCKSocketStreamTest: if get_cid() returns the host address or the "any" address, use the local communication address (loopback): VMADDR_CID_LOCAL. On Linux 6.9, apparently, the /dev/vsock device is now available but get_cid() returns VMADDR_CID_ANY (-1).

* bpo-40297: Fix test_socket.CANTest.testSendFrame (GH-19548)Miss Islington (bot)2021-05-041-2/+1
| | | | | | | | | | | | | The address tuple for CAN_RAW no longer returns the address family after the introduction of CAN ISO-TP support in a30f6d45ac3. However, updating test_socket.CANTest.testSendFrame was missed as part of the change, so the test incorrectly attempts to index past the last tuple item to retrieve the address family. This removes the now-redundant check for equality against socket.AF_CAN, as the tuple will not contain the address family.

| | | | | | | | | | | Support for RFCOMM, L2CAP, HCI, SCO is based on the BTPROTO_* macros being defined. Winsock only supports RFCOMM, even though it has a BTHPROTO_L2CAP macro. L2CAP support would build on windows, but not necessarily work. This also adds some basic unittests for constants (all of which existed prior to this commit, just not on windows) and creating sockets. pair: Nate Duarte <slacknate@gmail.com>
* bpo-37085: Expose SocketCAN bcm_msg_head flags (#13646)karl ding2019-07-311-0/+13
| | | | | | | | | | | | | | | | | | | | | | | | Expose the CAN_BCM SocketCAN constants used in the bcm_msg_head struct flags (provided by <linux/can/bcm.h>) under the socket library. This adds the following constants with a CAN_BCM prefix: * SETTIMER * STARTTIMER * TX_COUNTEVT * TX_ANNOUNCE * TX_CP_CAN_ID * RX_FILTER_ID * RX_CHECK_DLC * RX_NO_AUTOTIMER * RX_ANNOUNCE_RESUME * TX_RESET_MULTI_IDX * RX_RTR_FRAME * CAN_FD_FRAME The CAN_FD_FRAME flag was introduced in the 4.8 kernel, while the other ones were present since SocketCAN drivers were mainlined in 2.6.25. As such, it is probably unnecessary to guard against these constants being missing.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | At the moment you can definitely use UDPLITE sockets on Linux systems, but it would be good if this support were formalized such that you can detect support at runtime easily. At the moment, to make and use a UDPLITE socket requires something like the following code: ``` >>> import socket >>> a = socket.socket(socket.AF_INET, socket.SOCK_DGRAM, 136) >>> b = socket.socket(socket.AF_INET, socket.SOCK_DGRAM, 136) >>> a.bind(('localhost', 44444)) >>> b.sendto(b'test'*256, ('localhost', 44444)) >>> b.setsockopt(136, 10, 16) >>> b.sendto(b'test'*256, ('localhost', 44444)) >>> b.setsockopt(136, 10, 32) >>> b.sendto(b'test'*256, ('localhost', 44444)) >>> b.setsockopt(136, 10, 64) >>> b.sendto(b'test'*256, ('localhost', 44444)) ``` If you look at this through Wireshark, you can see that the packets are different in that the checksums and checksum coverages change. With the pull request that I am submitting momentarily, you could do the following code instead: ``` >>> import socket >>> a = socket.socket(socket.AF_INET, socket.SOCK_DGRAM, socket.IPPROTO_UDPLITE) >>> b = socket.socket(socket.AF_INET, socket.SOCK_DGRAM, socket.IPPROTO_UDPLITE) >>> a.bind(('localhost', 44444)) >>> b.sendto(b'test'*256, ('localhost', 44444)) >>> b.set_send_checksum_coverage(16) >>> b.sendto(b'test'*256, ('localhost', 44444)) >>> b.set_send_checksum_coverage(32) >>> b.sendto(b'test'*256, ('localhost', 44444)) >>> b.set_send_checksum_coverage(64) >>> b.sendto(b'test'*256, ('localhost', 44444)) ``` One can also detect support for UDPLITE just by checking ``` >>> hasattr(socket, 'IPPROTO_UDPLITE') ``` https://bugs.python.org/issue37345

Moreover, the test now checks sock.gettimeout() rather than a functional test on recv(). * Replace time.time() with time.monotonic() * Add socket_setdefaulttimeout() context manager to restore the default timeout when the test completes. * Remove testConnect(): accept() wasn't blocking and testAccept() already tests non-blocking accept(). * Remove accept() functional test from testInitNonBlocking(): already tested by testAccept() * Rewrite testSetBlocking() with a new assert_sock_timeout() method * Use addCleanup() and context manager to close sockets * Replace assertTrue(x < y) with assertLess(x, y)

* Fix tests in test_socket to use correctly CMSG_LEN (GH-9594)Pablo Galindo2018-09-271-2/+3
| | | | | | | | | | | | | After some failures in AMD64 FreeBSD CURRENT Debug 3.x buildbots regarding tests in test_socket that are using testFDPassSeparateMinSpace(), FreeBDS revision 337423 was pointed out to be the reason the test started to fail. A close examination of the manpage for cmsg_space(3) reveals that the number of file descriptors needs to be taken into account when using CMSG_LEN(). This commit fixes tests in test_socket to use correctly CMSG_LEN, taking into account the number of FDs.
