| * ima: free duplicate measurement memoryRoberto Sassu2011-12-192-2/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | Info about new measurements are cached in the iint for performance. When the inode is flushed from cache, the associated iint is flushed as well. Subsequent access to the inode will cause the inode to be re-measured and will attempt to add a duplicate entry to the measurement list. This patch frees the duplicate measurement memory, fixing a memory leak. Signed-off-by: Roberto Sassu <roberto.sassu@polito.it> Signed-off-by: Mimi Zohar <zohar@us.ibm.com> Cc: stable@vger.kernel.org

| | | | | | | | | | | | | | | | | | | | | | | | | | | | The 'aabool' wrappers actually pass off to the 'bool' parse functions, so you should use the same check function. Similarly for aauint and uint. (Note that 'bool' module parameters also allow 'int', which is why you got away with this, but that's changing very soon.)

| | * evm: digital signature verification supportDmitry Kasatkin2011-11-093-30/+142
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds support for digital signature verification to EVM. With this feature file metadata can be protected using digital signature instead of an HMAC. When building an image, which has to be flashed to different devices, an HMAC cannot be used to sign file metadata, because the HMAC key should be different on every device.

| | * integrity: digital signature verification using multiple keyringsDmitry Kasatkin2011-11-094-0/+84
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Define separate keyrings for each of the different use cases - evm, ima, and modules. Using different keyrings improves search performance, and also allows "locking" specific keyring to prevent adding new keys. This is useful for evm and module keyrings, when keys are usually only added from initramfs. Signed-off-by: Dmitry Kasatkin <dmitry.kasatkin@intel.com>
| | * crypto: digital signature verification supportDmitry Kasatkin2011-11-095-0/+453
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch implements RSA digital signature verification using GnuPG library. The format of the signature and the public key is defined by their respective headers. The signature header contains version information, algorithm, and keyid, which was used to generate the signature. The key header contains version and algorythim type. The payload of the signature and the key are multi-precision integers. The signing and key management utilities evm-utils provide functionality to generate signatures and load keys into the kernel keyring. When the key is added to the kernel keyring, the keyid defines the name of the key. Signed-off-by: Dmitry Kasatkin <dmitry.kasatkin@intel.com> Acked-by: Mimi Zohar <zohar@us.ibm.com>
| | * crypto: GnuPG based MPI lib - additional sources (part 4)Dmitry Kasatkin2011-11-0912-0/+1400
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Adds the multi-precision-integer maths library which was originally taken from GnuPG and ported to the kernel by (among others) David Howells. This version is taken from Fedora kernel 2.6.32-71.14.1.el6. The difference is that checkpatch reported errors and warnings have been fixed. This library is used to implemenet RSA digital signature verification used in IMA/EVM integrity protection subsystem. Due to patch size limitation, the patch is divided into 4 parts. This code is unnecessary for RSA digital signature verification, but for completeness it is included here and can be compiled, if CONFIG_MPILIB_EXTRA is enabled.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It's incorrect to assume that buffers returned by the TPM 10 bytes long are always error reports. This patches parses the error field in its header instead. The error report is now being printed using dev_err() instead of dev_dbg(), making it easier for users to provide more detailed bug reports.

However, Kconfig uses the broader ARCH_MXS symbol and this way even makes the fec-driver default for MX23. Adapt Kconfig to use the more precise SOC_IMX28 as well.

This was our goal but it is not yet achieved: a stopped-but-resumed tracee can clone the running thread which can initiate another group-stop. Remove WARN_ON_ONCE(!current->ptrace). 2. A new thread always starts with ->jobctl = 0. If it is auto-attached and this group is stopped, __ptrace_unlink() sets JOBCTL_STOP_PENDING but JOBCTL_STOP_SIGMASK part is zero, this triggers WANR_ON(!signr) in do_jobctl_trap() if another debugger attaches. Change __ptrace_unlink() to set the artificial SIGSTOP for report. Alternatively we could change ptrace_init_task() to copy signr from current, but this means we can copy it for no reason and hide the possible similar problems.
