      Select VIRT_TO_BUS directly where needed · 4febd95a
      Stephen Rothwell authored
      In commit 887cbce0 ("arch Kconfig: centralise ARCH_NO_VIRT_TO_BUS")
      I introduced the config sybmol HAVE_VIRT_TO_BUS and selected that where
      needed.  I am not sure what I was thinking.  Instead, just directly
      select VIRT_TO_BUS where it is needed.

      Fix: compat_rw_copy_check_uvector() misuse in aio, readv, writev, and security keys · 8aec0f5d
      Mathieu Desnoyers authored
      Looking at mm/process_vm_access.c:process_vm_rw() and comparing it to
      compat_process_vm_rw() shows that the compatibility code requires an
      explicit "access_ok()" check before calling
      compat_rw_copy_check_uvector(). The same difference seems to appear when
      we compare fs/read_write.c:do_readv_writev() to
      fs/compat.c:compat_do_readv_writev().
      
      This subtle difference between the compat and non-compat requirements
      should probably be debated, as it seems to be error-prone. In fact,
      there are two others sites that use this function in the Linux kernel,
      and they both seem to get it wrong:
      
      Now shifting our attention to fs/aio.c, we see that aio_setup_iocb()
      also ends up calling compat_rw_copy_check_uvector() through
      aio_setup_vectored_rw(). Unfortunately, the access_ok() check appears to
      be missing. Same situation for
      security/keys/compat.c:compat_keyctl_instantiate_key_iov().
      
      I propose that we add the access_ok() check directly into
      compat_rw_copy_check_uvector(), so callers don't have to worry about it,
      and it therefore makes the compat call code similar to its non-compat
      counterpart. Place the access_ok() check in the same location where
      copy_from_user() can trigger a -EFAULT error in the non-compat code, so
      the ABI behaviors are alike on both compat and non-compat.
      
      While we are here, fix compat_do_readv_writev() so it checks for
      compat_rw_copy_check_uvector() negative return values.
      
      And also, fix a memory leak in compat_keyctl_instantiate_key_iov() error
      handling.

      vfs: fix pipe counter breakage · a930d879
      Al Viro authored
      If you open a pipe for neither read nor write, the pipe code will not
      add any usage counters to the pipe, causing the 'struct pipe_inode_info"
      to be potentially released early.
      
      That doesn't normally matter, since you cannot actually use the pipe,
      but the pipe release code - particularly fasync handling - still expects
      the actual pipe infrastructure to all be there.  And rather than adding
      NULL pointer checks, let's just disallow this case, the same way we
      already do for the named pipe ("fifo") case.
      
      This is ancient going back to pre-2.4 days, and until trinity, nobody
      naver noticed.

      keys: fix race with concurrent install_user_keyrings() · 0da9dfdd
      David Howells authored
      This fixes CVE-2013-1792.
      
      There is a race in install_user_keyrings() that can cause a NULL pointer
      dereference when called concurrently for the same user if the uid and
      uid-session keyrings are not yet created.  It might be possible for an
      unprivileged user to trigger this by calling keyctl() from userspace in
      parallel immediately after logging in.
      
      Assume that we have two threads both executing lookup_user_key(), both
      looking for KEY_SPEC_USER_SESSION_KEYRING.
      
      	THREAD A			THREAD B
      	===============================	===============================
      					==>call install_user_keyrings();
      	if (!cred->user->session_keyring)
      	==>call install_user_keyrings()
      					...
      					user->uid_keyring = uid_keyring;
      	if (user->uid_keyring)
      		return 0;
      	<==
      	key = cred->user->session_keyring [== NULL]
      					user->session_keyring = session_keyring;
      	atomic_inc(&key->usage); [oops]
      
      At the point thread A dereferences cred->user->session_keyring, thread B
      hasn't updated user->session_keyring yet, but thread A assumes it is
      populated because install_user_keyrings() returned ok.
      
      The race window is really small but can be exploited if, for example,
      thread B is interrupted or preempted after initializing uid_keyring, but
      before doing setting session_keyring.
      
      This couldn't be reproduced on a stock kernel.  However, after placing
      systemtap probe on 'user->session_keyring = session_keyring;' that
      introduced some delay, the kernel could be crashed reliably.
      
      Fix this by checking both pointers before deciding whether to return.
      Alternatively, the test could be done away with entirely as it is checked
      inside the mutex - but since the mutex is global, that may not be the best
      way.

      xen: arm: mandate EABI and use generic atomic operations. · 85323a99
      Ian Campbell authored
      Rob Herring has observed that c81611c4 "xen: event channel arrays are
      xen_ulong_t and not unsigned long" introduced a compile failure when building
      without CONFIG_AEABI:
      
      /tmp/ccJaIZOW.s: Assembler messages:
      /tmp/ccJaIZOW.s:831: Error: even register required -- `ldrexd r5,r6,[r4]'
      
      Will Deacon pointed out that this is because OABI does not require even base
      registers for 64-bit values. We can avoid this by simply using the existing
      atomic64_xchg operation and the same containerof trick as used by the cmpxchg
      macros. However since this code is used on memory which is shared with the
      hypervisor we require proper atomic instructions and cannot use the generic
      atomic64 callbacks (which are based on spinlocks), therefore add a dependency
      on !GENERIC_ATOMIC64. Since we already depend on !CPU_V6 there isn't much
      downside to this.
      
      While thinking about this we also observed that OABI has different struct
      alignment requirements to EABI, which is a problem for hypercall argument
      structs which are shared with the hypervisor and which must be in EABI layout.
      Since I don't expect people to want to run OABI kernels on Xen depend on
      CONFIG_AEABI explicitly too (although it also happens to be enforced by the
      !GENERIC_ATOMIC64 requirement too).

      The tty below tty_port might get destroyed by the tty layer
      while we hold a reference to it.
      So we have to carry tty_port around...
