+Subject: [PATCH] Fix rngd to open the entropy source with 'O_NOCTTY' flag
+
+When start-stop-daemon starts a rngd instance configured to use a tty
+device as its entropy source, the application crashes due to not being
+able to read from the entropy device. This is caused by
+start-stop-daemon calling setsid() before executing rngd, which
+disassociates the controlling terminal. When rngd attempts to open a
+hardware entropy source that's a tty device, per POSIX rules, the
+device becomes the controlling terminal for the process. Then rngd
+calls daemon(), which internally calls setsid(), and consequently
+disassociates the controlling terminal for the child. Meanwhile the
+parent rngd process exits. This results in tty device hanging up. By
+looking at the strace logs attached to the bug, it can be observed
+that although the parent rngd process is able to read() from the
+entropy source successfully, further attempts to read() by the child
+rngd process return 0. This complies with the POSIX, which states that
+read() calls on a hung up terminal shall return 0.
+
+Note that when rngd is started without start-stop-daemon, this problem
+does not happen because at the time of opening the entropy source rngd
+already has a controlling terminal.
+
+Prevent the entropy source from becoming the controlling terminal by
+passing 'O_NOCTTY' flag to open() when opening an entropy source. This
+flag prevents a tty device from becoming the controlling terminal for
+a process without a controlling terminal at the time of open().
+
+Thanks to John Bowler <jbowler@acm.org> for debugging the problem and
+pinpointing the issue as well as confirming the fix.

+Subject: [PATCH] Fix assemby textrels on rdrand_asm.S on PIC x86
+
+This patch updates the fixes in the assembly in rdrand_asm.S in
+sys-apps/rng-tools-5 so it won't generate textrels on PIC systems.
+The main fixes are in the use of leal in SETPTR for such systems, the rest is
+the usual PIC support stuff.
+
+This should fix Gentoo bug #469962 and help fix #518210
+
+This patch is released under the GPLv2 or a higher version license as is the
+original file as long as the author and the tester are credited.

+From: Gokturk Yuksek <gokturk@binghamton.edu>
+Subject: [PATCH] Fix rngd to open the entropy source with 'O_NOCTTY' flag
+
+When start-stop-daemon starts a rngd instance configured to use a tty
+device as its entropy source, the application crashes due to not being
+able to read from the entropy device. This is caused by
+start-stop-daemon calling setsid() before executing rngd, which
+disassociates the controlling terminal. When rngd attempts to open a
+hardware entropy source that's a tty device, per POSIX rules, the
+device becomes the controlling terminal for the process. Then rngd
+calls daemon(), which internally calls setsid(), and consequently
+disassociates the controlling terminal for the child. Meanwhile the
+parent rngd process exits. This results in tty device hanging up. By
+looking at the strace logs attached to the bug, it can be observed
+that although the parent rngd process is able to read() from the
+entropy source successfully, further attempts to read() by the child
+rngd process return 0. This complies with the POSIX, which states that
+read() calls on a hung up terminal shall return 0.
+
+Note that when rngd is started without start-stop-daemon, this problem
+does not happen because at the time of opening the entropy source rngd
+already has a controlling terminal.
+
+Prevent the entropy source from becoming the controlling terminal by
+passing 'O_NOCTTY' flag to open() when opening an entropy source. This
+flag prevents a tty device from becoming the controlling terminal for
+a process without a controlling terminal at the time of open().
+
+Thanks to John Bowler <jbowler@acm.org> for debugging the problem and
+pinpointing the issue as well as confirming the fix.
