+@c for a discussion of what follows.
+@cindex version number, for VCS snapshots
+Occasionally, we package snapshots of upstream's version control system
+(VCS) instead of formal releases.  This should remain exceptional,
+because it is up to upstream developers to clarify what the stable
+release is.  Yet, it is sometimes necessary.  So, what should we put in
+the @code{version} field?
+
+Clearly, we need to make the commit identifier of the VCS snapshot
+visible in the version string, but we also need to make sure that the
+version string is monotonically increasing so that @command{guix package
+--upgrade} can determine which version is newer.  Since commit
+identifiers, notably with Git, are not monotonically increasing, we add
+a revision number that we increase each time we upgrade to a newer
+snapshot.  The resulting version string looks like this:
+
+@example
+2.0.11-3.cabba9e
+  ^    ^    ^
+  |    |    `-- upstream commit ID
+  |    |
+  |    `--- Guix package revision
+  |
+latest upstream version
+@end example
+
+It is a good idea to strip commit identifiers in the @code{version}
+field to, say, 7 digits.  It avoids an aesthetic annoyance (assuming
+aesthetics have a role to play here) as well as problems related to OS
+limits such as the maximum shebang length (127 bytes for the Linux
+kernel.)  It is best to use the full commit identifiers in
+@code{origin}s, though, to avoid ambiguities.

+Subject: KEYS: Fix keyring ref leak in join_session_keyring()
+
+This fixes CVE-2016-0728.
+
+If a thread is asked to join as a session keyring the keyring that's already
+set as its session, we leak a keyring reference.
+
+This can be tested with the following program:
+
+	#include <stddef.h>
+	#include <stdio.h>
+	#include <sys/types.h>
+	#include <keyutils.h>
+
+	int main(int argc, const char *argv[])
+	{
+		int i = 0;
+		key_serial_t serial;
+
+		serial = keyctl(KEYCTL_JOIN_SESSION_KEYRING,
+				"leaked-keyring");
+		if (serial < 0) {
+			perror("keyctl");
+			return -1;
+		}
+
+		if (keyctl(KEYCTL_SETPERM, serial,
+			   KEY_POS_ALL | KEY_USR_ALL) < 0) {
+			perror("keyctl");
+			return -1;
+		}
+
+		for (i = 0; i < 100; i++) {
+			serial = keyctl(KEYCTL_JOIN_SESSION_KEYRING,
+					"leaked-keyring");
+			if (serial < 0) {
+				perror("keyctl");
+				return -1;
+			}
+		}
+
+		return 0;
+	}
+
+If, after the program has run, there something like the following line in
+/proc/keys:
+
+3f3d898f I--Q---   100 perm 3f3f0000     0     0 keyring   leaked-keyring: empty
+
+with a usage count of 100 * the number of times the program has been run,
+then the kernel is malfunctioning.  If leaked-keyring has zero usages or
+has been garbage collected, then the problem is fixed.
