* [3.10] gh-98740: Fix validation of conditional expressions in RE (GH-98764) ↵Serhiy Storchaka2022-11-031-26/+28
| | | | | | | | | | | | | | | | (GH-99046) In very rare circumstances the JUMP opcode could be confused with the argument of the opcode in the "then" part which doesn't end with the JUMP opcode. This led to incorrect detection of the final JUMP opcode and incorrect calculation of the size of the subexpression. NOTE: Changed return value of functions _validate_inner() and _validate_charset() in Modules/_sre/sre.c. Now they return 0 on success, -1 on failure, and 1 if the last op is JUMP (which usually is a failure). Previously they returned 1 on success and 0 on failure.

* [3.10] gh-97897: Prevent os.mkfifo and os.mknod segfaults with macOS 13 SDK ↵Miss Islington (bot)2022-10-061-8/+52
| | | | | | | | | | | | | (GH-97944) (#97967) The macOS 13 SDK includes support for the `mkfifoat` and `mknodat` system calls. Using the `dir_fd` option with either `os.mkfifo` or `os.mknod` could result in a segfault if cpython is built with the macOS 13 SDK but run on an earlier version of macOS. Prevent this by adding runtime support for detection of these system calls ("weaklinking") as is done for other newer syscalls on macOS.
