* KEYS: Preparse match dataDavid Howells2014-09-1611-51/+129
| | | | | | | | | | | | | | | | | Preparse the match data. This provides several advantages: (1) The preparser can reject invalid criteria up front. (2) The preparser can convert the criteria to binary data if necessary (the asymmetric key type really wants to do binary comparison of the key IDs). (3) The preparser can set the type of search to be performed. This means that it's not then a one-off setting in the key type. (4) The preparser can set an appropriate comparator function.

| * PKCS#7: Fix the parser cleanup to drain parsed out X.509 certsDavid Howells2014-09-161-20/+19
| | | | | | | | | | | | | | | | | | | | | | | | Fix the parser cleanup code to drain parsed out X.509 certs in the case that the decode fails and we jump to error_decode. The function is rearranged so that the same cleanup code is used in the success case as the error case - just that the message descriptor under construction is only released if it is still pointed to by the context struct at that point.

| * KEYS: Reinstate EPERM for a key type name beginning with a '.'David Howells2014-09-161-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Reinstate the generation of EPERM for a key type name beginning with a '.' in a userspace call. Types whose name begins with a '.' are internal only. The test was removed by: commit a4e3b8d79a5c6d40f4a9703abf7fe3abcc6c3b8d Author: Mimi Zohar <zohar@linux.vnet.ibm.com> Date: Thu May 22 14:02:23 2014 -0400 Subject: KEYS: special dot prefixed keyring name bug fix I think we want to keep the restriction on type name so that userspace can't add keys of a special internal type. Note that removal of the test causes several of the tests in the keyutils testsuite to fail.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The kernel print macros use the KBUILD_MODNAME, which is initialized to the module name. The current integrity/Makefile makes every file as its own module, so pr_xxx messages are prefixed with the file name instead of the module.

Unfortunately, the bprm filename is a relative pathname (eg. ./<dir>/filename). ima_bprm_check() selects between bprm->interp and bprm->filename. The following dump demonstrates the differences between using filename and interp. bprm->filename filename: ./foo.sh, pathname: /root/bin/foo.sh filename: ./foo.sh, pathname: /bin/dash bprm->interp filename: ./foo.sh, pathname: /root/bin/foo.sh filename: /bin/sh, pathname: /bin/dash In both cases the pathnames are currently the same. This patch removes usage of filename and interp in favor of d_absolute_path. Changes v3: - 11 extra bytes for "deleted" not needed (Mimi) - purpose "replace relative bprm filename with full pathname" (Mimi) Changes v2: - use d_absolute_path() instead of d_path to work in chroot environments.

EVM, before allowing a protected, security xattr to be written, verifies the existing 'security.evm' value is good. For newly created files without a security.evm label, this verification prevents writing any protected, security xattrs, until the file closes. Following is the example when this happens: fd = open("foo", O_CREAT | O_WRONLY, 0644); setxattr("foo", "security.SMACK64", value, sizeof(value), 0); close(fd); While INTEGRITY_NOXATTRS status is handled in other places, such as evm_inode_setattr(), it does not handle it in all cases in evm_protect_xattr(). By limiting the use of INTEGRITY_NOXATTRS to newly created files, we can now allow setting "protected" xattrs.

At some point this "worked", but that was likely due to a bit of dumb luck and sub-par testing (both inflicted by yours truly). This patch corrects these problems by basically gutting the code in favor of something less obtuse and restoring the NetLabel abstractions in the SELinux catmap glue code. Everything is working now, and if it decides to break itself in the future this code will be much easier to debug than the code it replaces. One noteworthy side effect of the changes is that it is no longer necessary to allocate a NetLabel catmap before calling one of the NetLabel APIs to set a bit in the catmap. NetLabel will automatically allocate the catmap nodes when needed, resulting in less allocations when the lowest bit is greater than 255 and less code in the LSMs. Cc: stable@vger.kernel.org Reported-by: Christian Evans <frodox@zoho.com> Signed-off-by: Paul Moore <pmoore@redhat.com> Tested-by: Casey Schaufler <casey@schaufler-ca.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The NetLabel category (catmap) functions have a problem in that they assume categories will be set in an increasing manner, e.g. the next category set will always be larger than the last. Unfortunately, this is not a valid assumption and could result in problems when attempting to set categories less than the startbit in the lowest catmap node. In some cases kernel panics and other nasties can result. This patch corrects the problem by checking for this and allocating a new catmap node instance and placing it at the front of the list.

* | | tpm: Provide a generic means to override the chip returned timeoutsJason Gunthorpe2014-07-293-21/+75
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some Atmel TPMs provide completely wrong timeouts from their TPM_CAP_PROP_TIS_TIMEOUT query. This patch detects that and returns new correct values via a DID/VID table in the TIS driver.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Regression in 41ab999c. Call to tpm_chip_put is missing. This will cause TPM device driver not to unload if tmp_get_random() is called.

* | | tpm: Add missing tpm_do_selftest to ST33 I2C driverJason Gunthorpe2014-07-291-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Most device drivers do call 'tpm_do_selftest' which executes a TPM_ContinueSelfTest. tpm_i2c_stm_st33 is just pointlessly different, I think it is bug. These days we have the general assumption that the TPM is usable by the kernel immediately after the driver is finished, so we can no longer defer the mandatory self test to userspace.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This reverts commit 4da6daf4d3df5a977e4623963f141a627fd2efce. Unfortunately, the commit in question caused problems with Bluetooth devices, specifically it caused them to get caught in the newly created BUG_ON() check. The AF_ALG problem still exists, but will be addressed in a future patch. Cc: stable@vger.kernel.org Signed-off-by: Paul Moore <pmoore@redhat.com>
