From 7707055082a7005ad94ba81e5240644db8c0324a
From: David Howells <dhowells@redhat.com>
Date: Tue Jan 26 16:28:17 2016 +0000
Subject: [PATCH] KEYS: Only apply KEY_FLAG_KEEP to a key if a parent keyring has it set
KEY_FLAG_KEEP should only be applied to a key if the keyring it is being
linked into has KEY_FLAG_KEEP set.
To this end, partially revert the following patch:
commit 1d6d167c2efcfe9539d9cffb1a1be9c92e39c2c0
Author: Mimi Zohar <zohar@linux.vnet.ibm.com>
Date: Thu Jan 7 07:46:36 2016 -0500
KEYS: refcount bug fix
to undo the change that made it unconditional (Mimi got it right the first
time).
Without undoing this change, it becomes impossible to delete, revoke or
invalidate keys added to keyrings through __key_instantiate_and_link()
where the keyring has itself been linked to. To test this, run the
following command sequence:
keyctl newring foo @s
keyctl add user a a %:foo
keyctl unlink %user:a %:foo
keyctl clear %:foo
With the commit mentioned above the third and fourth commands fail with
EPERM when they should succeed.

From 938f50fc744cb49892bd42c8f56bdfa63e82a27d Mon Sep 17 00:00:00 2001

Date: Sun, 10 Jan 2016 22:40:55 -0800
Subject: [PATCH] tty: Fix unsafe ldisc reference via ioctl(TIOCGETD)
ioctl(TIOCGETD) retrieves the line discipline id directly from the
ldisc because the line discipline id (c_line) in termios is untrustworthy;
userspace may have set termios via ioctl(TCSETS*) without actually
changing the line discipline via ioctl(TIOCSETD).
However, directly accessing the current ldisc via tty->ldisc is
unsafe; the ldisc ptr dereferenced may be stale if the line discipline
is changing via ioctl(TIOCSETD) or hangup.
Wait for the line discipline reference (just like read() or write())
to retrieve the "current" line discipline id.

The visor driver crashes in clie_5_attach() when a specially crafted USB
device without bulk-out endpoint is detected. This fix adds a check that
the device has proper configuration expected by the driver.
