[PATCH 0/3] Extended file stat functions [ver #2]
Implement a pair of new system calls to provide extended and further extensible stat functions. The third of the associated patches provides these new system calls: struct xstat_dev { unsigned int major; unsigned int minor; }; struct xstat_time { unsigned long long tv_sec; unsigned long long t... 29 Jun 2010 21:48

[PATCH 2/3] AFS: Use i_generation not i_version for the vnode uniquifier [ver #2]
Store the AFS vnode uniquifier in the i_generation field, not the i_version field of the inode struct. i_version can then be given the AFS data version number.

[PATCH 2/2] Yama: add PTRACE exception tracking
Some application suites have external crash handlers that depend on being able to use PTRACE to generate crash reports (KDE, Chromium, etc). Since the inferior process generally knows the PID of the debugger, it can use PR_SET_PTRACER to allow a specific PID and its descendants to perform the PTRACE instead of only... 29 Jun 2010 21:48

[PATCH 0/2] Yama: add PTRACE exception tracking
The primary exception to Yama's descendant-based PTRACE restrictions is when an application has a predefined crash handler that is spawned in parallel with the crashed application (e.g. KDE, Chromium). These applications want to bypass the common RLIMIT_CORE=0, and gather state information from the process for ups... 29 Jun 2010 20:43

[PATCH 1/2] security: create task_free security callback
The current LSM interface to cred_free is not sufficient for allowing an LSM to track the life and death of a task. This patch adds the task_free hook so that an LSM can clean up resources on task death.
