This document only -covers the kernel-level portion. For command-line examples of how to -use encryption, see the documentation for the userspace tool `fscrypt -<https://github.com/google/fscrypt>`_. Also, it is recommended to use -the fscrypt userspace tool, or other existing userspace tools such as -`fscryptctl <https://github.com/google/fscryptctl>`_ or `Android's key -management system -<https://source.android.com/security/encryption/file-based>`_, over -using the kernel's API directly. Using existing tools reduces the -chance of introducing your own security bugs. (Nevertheless, for -completeness this documentation covers the kernel's API anyway.) - -Unlike dm-crypt, fscrypt operates at the filesystem level rather than -at the block device level. This allows it to encrypt different files -with different keys and to have unencrypted files on the same -filesystem. This is useful for multi-user systems where each user's -data-at-rest needs to be cryptographically isolated from the others. -However, except for filenames, fscrypt does not encrypt filesystem -metadata. - -Unlike eCryptfs, which is a stacked filesystem, fscrypt is integrated -directly into supported filesystems --- currently ext4, F2FS, and -UBIFS. This allows encrypted files to be read and written without -caching both the decrypted and encrypted pages in the pagecache, -thereby nearly halving the memory used and bringing it in line with -unencrypted files. Similarly, half as many dentries and inodes are -needed. eCryptfs also limits encrypted filenames to 143 bytes, -causing application compatibility issues; fscrypt allows the full 255 -bytes (NAME_MAX). Finally, unlike eCryptfs, the fscrypt API can be -used by unprivileged users, with no need to mount anything. - -fscrypt does not support encrypting files in-place. Instead, it -supports marking an empty directory as encrypted. Then, after -userspace provides the key, all regular files, directories, and -symbolic links created in that directory tree are transparently -encrypted. - -Threat model -============ - -Offline attacks ---------------- - -Provided that userspace chooses a strong encryption key, fscrypt -protects the confidentiality of file contents and filenames in the -event of a single point-in-time permanent offline compromise of the -block device content. fscrypt does not protect the confidentiality of -non-filename metadata, e.g. file sizes, file permissions, file -timestamps, and extended attributes. Also, the existence and location -of holes (unallocated blocks which logically contain all zeroes) in -files is not protected. - -fscrypt is not guaranteed to protect confidentiality or authenticity -if an attacker is able to manipulate the filesystem offline prior to -an authorized user later accessing the filesystem. - -Online attacks --------------- - -fscrypt (and storage encryption in general) can only provide limited -protection, if any at all, against online attacks. In detail: - -fscrypt is only resistant to side-channel attacks, such as timing or -electromagnetic attacks, to the extent that the underlying Linux -Cryptographic API algorithms are. If a vulnerable algorithm is used, -such as a table-based implementation of AES, it may be possible for an -attacker to mount a side channel attack against the online system. -Side channel attacks may also be mounted against applications -consuming decrypted data. - -After an encryption key has been provided, fscrypt is not designed to -hide the plaintext file contents or filenames from other users on the -same system, regardless of the visibility of the keyring key. -Instead, existing access control mechanisms such as file mode bits, -POSIX ACLs, LSMs, or mount namespaces should be used for this purpose. -Also note that as long as the encryption keys are *anywhere* in -memory, an online attacker can necessarily compromise them by mounting -a physical attack or by exploiting any kernel security vulnerability -which provides an arbitrary memory read primitive. - -While it is ostensibly possible to "evict" keys from the system, -recently accessed encrypted files will remain accessible at least -until the filesystem is unmounted or the VFS caches are dropped, e.g. -using ``echo 2 > /proc/sys/vm/drop_caches``. Even after that, if the -RAM is compromised before being powered off, it will likely still be -possible to recover portions of the plaintext file contents, if not -some of the encryption keys as well. (Since Linux v4.12, all -in-kernel keys related to fscrypt are sanitized before being freed. -However, userspace would need to do its part as well.) - -Currently, fscrypt does not prevent a user from maliciously providing -an incorrect key for another user's existing encrypted files. A -protection against this is planned. - -Key hierarchy -============= - -Master Keys ------------ - -Each encrypted directory tree is protected by a *master key*. Master -keys can be up to 64 bytes long, and must be at least as long as the -greater of the key length needed by the contents and filenames -encryption modes being used. For example, if AES-256-XTS is used for -contents encryption, the master key must be 64 bytes (512 bits). Note -that the XTS mode is defined to require a key twice as long as that -required by the underlying block cipher. - -To "unlock" an encrypted directory tree, userspace must provide the -appropriate master key. There can be any number of master keys, each -of which protects any number of directory trees on any number of -filesystems. - -Userspace should generate master keys either using a cryptographically -secure random number generator, or by using a KDF (Key Derivation -Function). Note that whenever a KDF is used to "stretch" a -lower-entropy secret such as a passphrase, it is critical that a KDF -designed for this purpose be used, such as scrypt, PBKDF2, or Argon2. - -Per-file keys -------------- - -Master keys are not used to encrypt file contents or names directly. -Instead, a unique key is derived for each encrypted file, including -each regular file, directory, and symbolic link. This has several -advantages: - -- In cryptosystems, the same key material should never be used for - different purposes. Using the master key as both an XTS key for - contents encryption and as a CTS-CBC key for filenames encryption - would violate this rule. -- Per-file keys simplify the choice of IVs (Initialization Vectors) - for contents encryption. Without per-file keys, to ensure IV - uniqueness both the inode and logical block number would need to be - encoded in the IVs. This would make it impossible to renumber - inodes, which e.g. ``resize2fs`` can do when resizing an ext4 - filesystem. With per-file keys, it is sufficient to encode just the - logical block number in the IVs. -- Per-file keys strengthen the encryption of filenames, where IVs are - reused out of necessity. With a unique key per directory, IV reuse - is limited to within a single directory. -- Per-file keys allow individual files to be securely erased simply by - securely erasing their keys. (Not yet implemented.) - -A KDF (Key Derivation Function) is used to derive per-file keys from -the master key. This is done instead of wrapping a randomly-generated -key for each file because it reduces the size of the encryption xattr, -which for some filesystems makes the xattr more likely to fit in-line -in the filesystem's inode table. With a KDF, only a 16-byte nonce is -required --- long enough to make key reuse extremely unlikely. A -wrapped key, on the other hand, would need to be up to 64 bytes --- -the length of an AES-256-XTS key. Furthermore, currently there is no -requirement to support unlocking a file with multiple alternative -master keys or to support rotating master keys. Instead, the master -keys may be wrapped in userspace, e.g. as done by the `fscrypt -<https://github.com/google/fscrypt>`_ tool. - -The current KDF encrypts the master key using the 16-byte nonce as an -AES-128-ECB key. The output is used as the derived key. If the -output is longer than needed, then it is truncated to the needed -length. Truncation is the norm for directories and symlinks, since -those use the CTS-CBC encryption mode which requires a key half as -long as that required by the XTS encryption mode. - -Note: this KDF meets the primary security requirement, which is to -produce unique derived keys that preserve the entropy of the master -key, assuming that the master key is already a good pseudorandom key. -However, it is nonstandard and has some problems such as being -reversible, so it is generally considered to be a mistake! It may be -replaced with HKDF or another more standard KDF in the future. - -Encryption modes and usage -========================== - -fscrypt allows one encryption mode to be specified for file contents -and one encryption mode to be specified for filenames. Different -directory trees are permitted to use different encryption modes. -Currently, the following pairs of encryption modes are supported: - -- AES-256-XTS for contents and AES-256-CTS-CBC for filenames -- AES-128-CBC for contents and AES-128-CTS-CBC for filenames -- Speck128/256-XTS for contents and Speck128/256-CTS-CBC for filenames - -It is strongly recommended to use AES-256-XTS for contents encryption. -AES-128-CBC was added only for low-powered embedded devices with -crypto accelerators such as CAAM or CESA that do not support XTS. - -Similarly, Speck128/256 support was only added for older or low-end -CPUs which cannot do AES fast enough -- especially ARM CPUs which have -NEON instructions but not the Cryptography Extensions -- and for which -it would not otherwise be feasible to use encryption at all. It is -not recommended to use Speck on CPUs that have AES instructions. -Speck support is only available if it has been enabled in the crypto -API via CONFIG_CRYPTO_SPECK. Also, on ARM platforms, to get -acceptable performance CONFIG_CRYPTO_SPECK_NEON must be enabled. - -New encryption modes can be added relatively easily, without changes -to individual filesystems. However, authenticated encryption (AE) -modes are not currently supported because of the difficulty of dealing -with ciphertext expansion. - -For file contents, each filesystem block is encrypted independently. -Currently, only the case where the filesystem block size is equal to -the system's page size (usually 4096 bytes) is supported. With the -XTS mode of operation (recommended), the logical block number within -the file is used as the IV. With the CBC mode of operation (not -recommended), ESSIV is used; specifically, the IV for CBC is the -logical block number encrypted with AES-256, where the AES-256 key is -the SHA-256 hash of the inode's data encryption key. - -For filenames, the full filename is encrypted at once. Because of the -requirements to retain support for efficient directory lookups and -filenames of up to 255 bytes, a constant initialization vector (IV) is -used. However, each encrypted directory uses a unique key, which -limits IV reuse to within a single directory. Note that IV reuse in -the context of CTS-CBC encryption means that when the original -filenames share a common prefix at least as long as the cipher block -size (16 bytes for AES), the corresponding encrypted filenames will -also share a common prefix. This is undesirable; it may be fixed in -the future by switching to an encryption mode that is a strong -pseudorandom permutation on arbitrary-length messages, e.g. the HEH -(Hash-Encrypt-Hash) mode. - -Since filenames are encrypted with the CTS-CBC mode of operation, the -plaintext and ciphertext filenames need not be multiples of the AES -block size, i.e. 16 bytes. However, the minimum size that can be -encrypted is 16 bytes, so shorter filenames are NUL-padded to 16 bytes -before being encrypted. In addition, to reduce leakage of filename -lengths via their ciphertexts, all filenames are NUL-padded to the -next 4, 8, 16, or 32-byte boundary (configurable). 32 is recommended -since this provides the best confidentiality, at the cost of making -directory entries consume slightly more space. Note that since NUL -(``\0``) is not otherwise a valid character in filenames, the padding -will never produce duplicate plaintexts. - -Symbolic link targets are considered a type of filename and are -encrypted in the same way as filenames in directory entries. Each -symlink also uses a unique key; hence, the hardcoded IV is not a -problem for symlinks. - -User API -======== - -Setting an encryption policy ----------------------------- - -The FS_IOC_SET_ENCRYPTION_POLICY ioctl sets an encryption policy on an -empty directory or verifies that a directory or regular file already -has the specified encryption policy. It takes in a pointer to a -:c:type:`struct fscrypt_policy`, defined as follows:: - - #define FS_KEY_DESCRIPTOR_SIZE 8 - - struct fscrypt_policy { - __u8 version; - __u8 contents_encryption_mode; - __u8 filenames_encryption_mode; - __u8 flags; - __u8 master_key_descriptor[FS_KEY_DESCRIPTOR_SIZE]; - }; - -This structure must be initialized as follows: - -- ``version`` must be 0. - -- ``contents_encryption_mode`` and ``filenames_encryption_mode`` must - be set to constants from ``<linux/fs.h>`` which identify the - encryption modes to use. If unsure, use - FS_ENCRYPTION_MODE_AES_256_XTS (1) for ``contents_encryption_mode`` - and FS_ENCRYPTION_MODE_AES_256_CTS (4) for - ``filenames_encryption_mode``. - -- ``flags`` must be set to a value from ``<linux/fs.h>`` which - identifies the amount of NUL-padding to use when encrypting - filenames. If unsure, use FS_POLICY_FLAGS_PAD_32 (0x3). - -- ``master_key_descriptor`` specifies how to find the master key in - the keyring; see `Adding keys`_. It is up to userspace to choose a - unique ``master_key_descriptor`` for each master key. The e4crypt - and fscrypt tools use the first 8 bytes of - ``SHA-512(SHA-512(master_key))``, but this particular scheme is not - required. Also, the master key need not be in the keyring yet when - FS_IOC_SET_ENCRYPTION_POLICY is executed. However, it must be added - before any files can be created in the encrypted directory. - -If the file is not yet encrypted, then FS_IOC_SET_ENCRYPTION_POLICY -verifies that the file is an empty directory. If so, the specified -encryption policy is assigned to the directory, turning it into an -encrypted directory. After that, and after providing the -corresponding master key as described in `Adding keys`_, all regular -files, directories (recursively), and symlinks created in the -directory will be encrypted, inheriting the same encryption policy. -The filenames in the directory's entries will be encrypted as well. - -Alternatively, if the file is already encrypted, then -FS_IOC_SET_ENCRYPTION_POLICY validates that the specified encryption -policy exactly matches the actual one. If they match, then the ioctl -returns 0. Otherwise, it fails with EEXIST.

Instead, prefer to -generate and manage any needed salt(s) in userspace. - -Adding keys ------------ - -To provide a master key, userspace must add it to an appropriate -keyring using the add_key() system call (see: -``Documentation/security/keys/core.rst``).

Generally, if only -processes belonging to a specific user need to access a given -encrypted directory and no session keyring has been installed, then -that directory's key should be placed in that user's user session -keyring or user keyring. Otherwise, a session keyring should be -installed if needed, and the key should be linked into that session -keyring, or in a keyring linked into that session keyring. - -Note: introducing the complex visibility semantics of keyrings here -was arguably a mistake --- especially given that by design, after any -process successfully opens an encrypted file (thereby setting up the -per-file key), possessing the keyring key is not actually required for -any process to read/write the file until its in-memory inode is -evicted. In the future there probably should be a way to provide keys -directly to the filesystem instead, which would make the intended -semantics clearer. - -Access semantics -================ - -With the key ------------- - -With the encryption key, encrypted regular files, directories, and -symlinks behave very similarly to their unencrypted counterparts --- -after all, the encryption is intended to be transparent. However, -astute users may notice some differences in behavior: - -- Unencrypted files, or files encrypted with a different encryption - policy (i.e. different key, modes, or flags), cannot be renamed or - linked into an encrypted directory; see `Encryption policy - enforcement`_. Attempts to do so will fail with EPERM. However, - encrypted files can be renamed within an encrypted directory, or - into an unencrypted directory. - -- Direct I/O is not supported on encrypted files. Attempts to use - direct I/O on such files will fall back to buffered I/O. - -- The fallocate operations FALLOC_FL_COLLAPSE_RANGE, - FALLOC_FL_INSERT_RANGE, and FALLOC_FL_ZERO_RANGE are not supported - on encrypted files and will fail with EOPNOTSUPP. - -- Online defragmentation of encrypted files is not supported. The - EXT4_IOC_MOVE_EXT and F2FS_IOC_MOVE_RANGE ioctls will fail with - EOPNOTSUPP. - -- The ext4 filesystem does not support data journaling with encrypted - regular files. It will fall back to ordered data mode instead. - -- DAX (Direct Access) is not supported on encrypted files. - -- The st_size of an encrypted symlink will not necessarily give the - length of the symlink target as required by POSIX. It will actually - give the length of the ciphertext, which will be slightly longer - than the plaintext due to NUL-padding and an extra 2-byte overhead. - -- The maximum length of an encrypted symlink is 2 bytes shorter than - the maximum length of an unencrypted symlink. For example, on an - EXT4 filesystem with a 4K block size, unencrypted symlinks can be up - to 4095 bytes long, while encrypted symlinks can only be up to 4093 - bytes long (both lengths excluding the terminating null). - -Note that mmap *is* supported. This is possible because the pagecache -for an encrypted file contains the plaintext, not the ciphertext. - -Without the key ---------------- - -Some filesystem operations may be performed on encrypted regular -files, directories, and symlinks even before their encryption key has -been provided: - -- File metadata may be read, e.g. using stat(). - -- Directories may be listed, in which case the filenames will be - listed in an encoded form derived from their ciphertext. The - current encoding algorithm is described in `Filename hashing and - encoding`_. The algorithm is subject to change, but it is - guaranteed that the presented filenames will be no longer than - NAME_MAX bytes, will not contain the ``/`` or ``\0`` characters, and - will uniquely identify directory entries. - - The ``.`` and ``..`` directory entries are special. They are always - present and are not encrypted or encoded. - -- Files may be deleted. That is, nondirectory files may be deleted - with unlink() as usual, and empty directories may be deleted with - rmdir() as usual. Therefore, ``rm`` and ``rm -r`` will work as - expected. - -- Symlink targets may be read and followed, but they will be presented - in encrypted form, similar to filenames in directories. Hence, they - are unlikely to point to anywhere useful. - -Without the key, regular files cannot be opened or truncated. -Attempts to do so will fail with ENOKEY. This implies that any -regular file operations that require a file descriptor, such as -read(), write(), mmap(), fallocate(), and ioctl(), are also forbidden. - -Also without the key, files of any type (including directories) cannot -be created or linked into an encrypted directory, nor can a name in an -encrypted directory be the source or target of a rename, nor can an -O_TMPFILE temporary file be created in an encrypted directory. All -such operations will fail with ENOKEY. - -It is not currently possible to backup and restore encrypted files -without the encryption key. This would require special APIs which -have not yet been implemented. - -Encryption policy enforcement -============================= - -After an encryption policy has been set on a directory, all regular -files, directories, and symbolic links created in that directory -(recursively) will inherit that encryption policy. Special files --- -that is, named pipes, device nodes, and UNIX domain sockets --- will -not be encrypted. - -Except for those special files, it is forbidden to have unencrypted -files, or files encrypted with a different encryption policy, in an -encrypted directory tree. Attempts to link or rename such a file into -an encrypted directory will fail with EPERM. This is also enforced -during ->lookup() to provide limited protection against offline -attacks that try to disable or downgrade encryption in known locations -where applications may later write sensitive data. It is recommended -that systems implementing a form of "verified boot" take advantage of -this by validating all top-level encryption policies prior to access. - -Implementation details -====================== - -Encryption context ------------------- - -An encryption policy is represented on-disk by a :c:type:`struct -fscrypt_context`. It is up to individual filesystems to decide where -to store it, but normally it would be stored in a hidden extended -attribute. It should *not* be exposed by the xattr-related system -calls such as getxattr() and setxattr() because of the special -semantics of the encryption xattr. (In particular, there would be -much confusion if an encryption policy were to be added to or removed -from anything other than an empty directory.) The struct is defined -as follows:: - - #define FS_KEY_DESCRIPTOR_SIZE 8 - #define FS_KEY_DERIVATION_NONCE_SIZE 16 - - struct fscrypt_context { - u8 format; - u8 contents_encryption_mode; - u8 filenames_encryption_mode; - u8 flags; - u8 master_key_descriptor[FS_KEY_DESCRIPTOR_SIZE]; - u8 nonce[FS_KEY_DERIVATION_NONCE_SIZE]; - }; - -Note that :c:type:`struct fscrypt_context` contains the same -information as :c:type:`struct fscrypt_policy` (see `Setting an -encryption policy`_), except that :c:type:`struct fscrypt_context` -also contains a nonce. The nonce is randomly generated by the kernel -and is used to derive the inode's encryption key as described in -`Per-file keys`_. - -Data path changes ------------------ - -For the read path (->readpage()) of regular files, filesystems can -read the ciphertext into the page cache and decrypt it in-place. The -page lock must be held until decryption has finished, to prevent the -page from becoming visible to userspace prematurely. - -For the write path (->writepage()) of regular files, filesystems -cannot encrypt data in-place in the page cache, since the cached -plaintext must be preserved. Instead, filesystems must encrypt into a -temporary buffer or "bounce page", then write out the temporary -buffer. Some filesystems, such as UBIFS, already use temporary -buffers regardless of encryption. Other filesystems, such as ext4 and -F2FS, have to allocate bounce pages specially for encryption. - -Filename hashing and encoding ------------------------------ - -Modern filesystems accelerate directory lookups by using indexed -directories. An indexed directory is organized as a tree keyed by -filename hashes. When a ->lookup() is requested, the filesystem -normally hashes the filename being looked up so that it can quickly -find the corresponding directory entry, if any. - -With encryption, lookups must be supported and efficient both with and -without the encryption key. Clearly, it would not work to hash the -plaintext filenames, since the plaintext filenames are unavailable -without the key. (Hashing the plaintext filenames would also make it -impossible for the filesystem's fsck tool to optimize encrypted -directories.) Instead, filesystems hash the ciphertext filenames, -i.e. the bytes actually stored on-disk in the directory entries. When -asked to do a ->lookup() with the key, the filesystem just encrypts -the user-supplied name to get the ciphertext. - -Lookups without the key are more complicated. The raw ciphertext may -contain the ``\0`` and ``/`` characters, which are illegal in -filenames. Therefore, readdir() must base64-encode the ciphertext for -presentation. For most filenames, this works fine; on ->lookup(), the -filesystem just base64-decodes the user-supplied name to get back to -the raw ciphertext. - -However, for very long filenames, base64 encoding would cause the -filename length to exceed NAME_MAX. To prevent this, readdir() -actually presents long filenames in an abbreviated form which encodes -a strong "hash" of the ciphertext filename, along with the optional -filesystem-specific hash(es) needed for directory lookups. This -allows the filesystem to still, with a high degree of confidence, map -the filename given in ->lookup() back to a particular directory entry -that was previously listed by readdir(). See :c:type:`struct -fscrypt_digested_name` in the source for more details. - -Note that the precise way that filenames are presented to userspace -without the key is subject to change in the future. It is only meant -as a way to temporarily present valid filenames so that commands like -``rm -r`` work as expected on encrypted directories. diff --git a/Documentation/sysctl/fs.txt b/Documentation/sysctl/fs.txt index 35e17f748ca7..af5859b2d0f9 100644 --- a/Documentation/sysctl/fs.txt +++ b/Documentation/sysctl/fs.txt @@ -34,7 +34,9 @@ Currently, these files are in /proc/sys/fs: - overflowgid - pipe-user-pages-hard - pipe-user-pages-soft +- protected_fifos - protected_hardlinks +- protected_regular - protected_symlinks - suid_dumpable - super-max @@ -182,6 +184,24 @@ applied. ============================================================== +protected_fifos: + +The intent of this protection is to avoid unintentional writes to +an attacker-controlled FIFO, where a program expected to create a regular +file. + +When set to "0", writing to FIFOs is unrestricted. + +When set to "1" don't allow O_CREAT open on FIFOs that we don't own +in world writable sticky directories, unless they are owned by the +owner of the directory. + +When set to "2" it also applies to group writable sticky directories. + +This protection is based on the restrictions in Openwall. + +============================================================== + protected_hardlinks: A long-standing class of security issues is the hardlink-based @@ -202,6 +222,22 @@ This protection is based on the restrictions in Openwall and grsecurity. ============================================================== +protected_regular: + +This protection is similar to protected_fifos, but it +avoids writes to an attacker-controlled regular file, where a program +expected to create one. + +When set to "0", writing to regular files is unrestricted. + +When set to "1" don't allow O_CREAT open on regular files that we +don't own in world writable sticky directories, unless they are +owned by the owner of the directory. + +When set to "2" it also applies to group writable sticky directories. + +============================================================== + protected_symlinks: A long-standing class of security issues is the symlink-based diff --git a/MAINTAINERS b/MAINTAINERS index 414c3c43d276..13cc0bc83c1c 100644 --- a/MAINTAINERS +++ b/MAINTAINERS @@ -10221,6 +10221,7 @@ F: arch/alpha/kernel/srm_env.c STABLE BRANCH M: Greg Kroah-Hartman <gregkh@linuxfoundation.org> +M: Sasha Levin <sashal@kernel.org> L: stable@vger.kernel.org S: Supported F: Documentation/stable_kernel_rules.txt @@ -1,6 +1,6 @@ VERSION = 4 PATCHLEVEL = 4 -SUBLEVEL = 162 +SUBLEVEL = 166 EXTRAVERSION = NAME = Blurry Fish Butt @@ -306,11 +306,6 @@ HOSTCXX = g++ HOSTCFLAGS := -Wall -Wmissing-prototypes -Wstrict-prototypes -O2 -fomit-frame-pointer -std=gnu89 HOSTCXXFLAGS = -O2 -ifeq ($(shell $(HOSTCC) -v 2>&1 | grep -c "clang version"), 1) -HOSTCFLAGS += -Wno-unused-value -Wno-unused-parameter \ - -Wno-missing-field-initializers -fno-delete-null-pointer-checks -endif - # Decide whether to build built-in, modular, or both. # Normally, just do built-in. @@ -620,6 +615,26 @@ endif # $(dot-config) # Defaults to vmlinux, but the arch makefile usually adds further targets all: vmlinux +ifeq ($(cc-name),clang) +ifneq ($(CROSS_COMPILE),) +CLANG_TRIPLE ?= $(CROSS_COMPILE) +CLANG_TARGET := --target=$(notdir $(CLANG_TRIPLE:%-=%)) +ifeq ($(shell $(srctree)/scripts/clang-android.sh $(CC) $(CLANG_TARGET)), y) +$(error "Clang with Android --target detected.
