      X.509: Support parse long form of length octets in Authority Key Identifier · 04b00bdb
      Chun-Yi Lee authored
      Per X.509 spec in 4.2.1.1 section, the structure of Authority Key
      Identifier Extension is:
      
         AuthorityKeyIdentifier ::= SEQUENCE {
            keyIdentifier             [0] KeyIdentifier           OPTIONAL,
            authorityCertIssuer       [1] GeneralNames            OPTIONAL,
            authorityCertSerialNumber [2] CertificateSerialNumber OPTIONAL  }
      
         KeyIdentifier ::= OCTET STRING
      
      When a certificate also provides
      authorityCertIssuer and authorityCertSerialNumber then the length of
      AuthorityKeyIdentifier SEQUENCE is likely to long form format.
      e.g.
         The example certificate demos/tunala/A-server.pem in openssl source:
      
      X509v3 Authority Key Identifier:
          keyid:49:FB:45:72:12:C4:CC:E1:45:A1:D3:08:9E:95:C4:2C:6D:55:3F:17
          DirName:/C=NZ/L=Wellington/O=Really Irresponsible Authorisation Authority (RIAA)/OU=Cert-stamping/CN=Jackov al-Trades/emailAddress=none@fake.domain
          serial:00
      
      Current parsing rule of OID_authorityKeyIdentifier only take care the
      short form format, it causes load certificate to modsign_keyring fail:
      
      [   12.061147] X.509: Extension: 47
      [   12.075121] MODSIGN: Problem loading in-kernel X.509 certificate (-74)
      
      So, this patch add the parsing rule for support long form format against
      Authority Key Identifier.
      
      v3:
      Changed the size check in "Short Form length" case, we allow v[3] smaller
      then (vlen - 4) because authorityCertIssuer and authorityCertSerialNumber
      are also possible attach in AuthorityKeyIdentifier sequence.
      
      v2:
       - Removed comma from author's name.
       - Moved 'Short Form length' comment inside the if-body.
       - Changed the type of sub to size_t.
       - Use ASN1_INDEFINITE_LENGTH rather than writing 0x80 and 127.
       - Moved the key_len's value assignment before alter v.
       - Fixed the typo of octets.
       - Add 2 to v before entering the loop for calculate the length.
       - Removed the comment of check vlen.

      kernel: kallsyms: memory override issue, need check destination buffer length · e3f26752
      Chen Gang authored
        We don't export any symbols > 128 characters, but if we did then
        kallsyms_expand_symbol() would overflow the buffer handed to it.
        So we need check destination buffer length when copying.
      
        the related test:
          if we define an EXPORT function which name more than 128.
          will panic when call kallsyms_lookup_name by init_kprobes on booting.
          after check the length (provide this patch), it is ok.
      
        Implementaion:
          add additional destination buffer length parameter (maxlen)
          if uncompressed string is too long (>= maxlen), it will be truncated.
          not check the parameters whether valid, since it is a static function.

      genksyms: pass symbol-prefix instead of arch · d70f82ac
      James Hogan authored
      Pass symbol-prefix to genksyms instead of arch, so that the decision
      what symbol prefix to use is kept in one place.
      
      Basically genksyms used to take a -a $ARCH argument and it used that to
      determine whether to add an underscore symbol prefix. It's now changed
      to take a -s $SYMBOL_PREFIX argument so that the caller decides whether
      a symbol prefix is required. The build system then uses
      CONFIG_HAVE_UNDERSCORE_SYMBOL_PREFIX to determine whether to pass the
      argument.

      module: fix symbol versioning with symbol prefixes · a4b6a77b
      James Hogan authored
      Fix symbol versioning on architectures with symbol prefixes. Although
      the build was free from warnings the actual modules still wouldn't load
      as the ____versions table contained unprefixed symbol names, which were
      being compared against the prefixed symbol names when checking the
      symbol versions.
      
      This is fixed by modifying modpost to add the symbol prefix to the
      ____versions table it outputs (Modules.symvers still contains unprefixed
      symbol names). The check_modstruct_version() function is also fixed as
      it checks the version of the unprefixed "module_layout" symbol which
      would no longer work.

      CONFIG_SYMBOL_PREFIX: cleanup. · b92021b0
      Rusty Russell authored
      We have CONFIG_SYMBOL_PREFIX, which three archs define to the string
      "_".  But Al Viro broke this in "consolidate cond_syscall and
      SYSCALL_ALIAS declarations" (in linux-next), and he's not the first to
      do so.
      
      Using CONFIG_SYMBOL_PREFIX is awkward, since we usually just want to
      prefix it so something.  So various places define helpers which are
      defined to nothing if CONFIG_SYMBOL_PREFIX isn't set:
      
      1) include/asm-generic/unistd.h defines __SYMBOL_PREFIX.
      2) include/asm-generic/vmlinux.lds.h defines VMLINUX_SYMBOL(sym)
      3) include/linux/export.h defines MODULE_SYMBOL_PREFIX.
      4) include/linux/kernel.h defines SYMBOL_PREFIX (which differs from #7)
      5) kernel/modsign_certificate.S defines ASM_SYMBOL(sym)
      6) scripts/modpost.c defines MODULE_SYMBOL_PREFIX
      7) scripts/Makefile.lib defines SYMBOL_PREFIX on the commandline if
         CONFIG_SYMBOL_PREFIX is set, so that we have a non-string version
         for pasting.
      
      (arch/h8300/include/asm/linkage.h defines SYMBOL_NAME(), too).
      
      Let's solve this properly:
      1) No more generic prefix, just CONFIG_HAVE_UNDERSCORE_SYMBOL_PREFIX.
      2) Make linux/export.h usable from asm.
      3) Define VMLINUX_SYMBOL() and VMLINUX_SYMBOL_STR().
      4) Make everyone use them.

      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

      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.
