New submission from Christian Heimes: Linux 3.11 gets a new flag for open():
Quote from http://lwn.net/Articles/557314/ --- The new O_TMPFILE option to the open() and openat() system calls allows filesystems to optimize the creation of temporary files — files which need not be visible in the filesystem. When O_TMPFILE is present, the provided pathname is only used to locate the containing directory (and thus the filesystem where the temporary file should be). So, among other things, programs using O_TMPFILE should have fewer concerns about vulnerabilities resulting from symbolic link attacks. --- Tasks: - add O_TEMPFILE to posixmodule.c - use O_TEMPFILE in tempfile module when it's supported by the current kernel ---------- components: Extension Modules, Library (Lib) messages: 194569 nosy: christian.heimes priority: normal severity: normal stage: needs patch status: open title: Add and use O_TMPFILE for Linux 3.11 type: enhancement versions: Python 3.4 _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue18673> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
