bpo-40121: Fixes audit event raised on creating a new socket (GH-19238)

2020-03-31T11:57:06+00:00

(cherry picked from commit 63ba5cccf484b9ec23dfbf4cf7ffdc833eda98c3)

closes bpo-37405: Make socket.getsockname() always return a tuple for AF_CAN. (GH-14392) (GH-16018)

2019-09-12T10:34:28+00:00

This fixes a regression from 3.5. In recent releases, `getsockname()` in the AF_CAN case has returned a string.

bpo-37811: FreeBSD, OSX: fix poll(2) usage in sockets module (GH-15202)

2019-08-14T21:47:43+00:00

FreeBSD implementation of poll(2) restricts the timeout argument to be
either zero, or positive, or equal to INFTIM (-1).

Unless otherwise overridden, socket timeout defaults to -1. This value
is then converted to milliseconds (-1000) and used as argument to the
poll syscall. poll returns EINVAL (22), and the connection fails.

This bug was discovered during the EINTR handling testing, and the
reproduction code can be found in
https://bugs.python.org/issue23618 (see connect_eintr.py,
attached). On GNU/Linux, the example runs as expected.

This change is trivial:
If the supplied timeout value is negative, truncate it to -1.

bpo-37085: Expose SocketCAN bcm_msg_head flags (GH-13646)

2019-07-31T09:10:38+00:00

Expose the CAN_BCM SocketCAN constants used in the bcm_msg_head struct
flags (provided by ) 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.

bpo-36974: tp_print -> tp_vectorcall_offset and tp_reserved -> tp_as_async (GH-13464)

2019-05-31T02:13:39+00:00

Automatically replace
tp_print -> tp_vectorcall_offset
tp_compare -> tp_as_async
tp_reserved -> tp_as_async

bpo-37007: Implement socket.if_nametoindex(), if_indextoname() and if_nameindex() on Windows (GH-13522)

2019-05-29T21:02:37+00:00

bpo-32388: Remove cross-version binary compatibility requirement in tp_flags (GH-4944)

2019-05-29T20:12:38+00:00

It is now allowed to add new fields at the end of the PyTypeObject struct without having to allocate a dedicated compatibility flag in tp_flags.

This will reduce the risk of running out of bits in the 32-bit tp_flags value.

bpo-36842: Implement PEP 578 (GH-12613)

2019-05-23T15:45:22+00:00

Adds sys.audit, sys.addaudithook, io.open_code, and associated C APIs.

bpo-29515: add missing socket.IPPROTO_* constants on Windows (GH-12183)

2019-03-28T14:20:30+00:00
