2014-03-19selinux: put the mmap() DAC controls before the MAC controlsPaul Moore1-12/+8
It turns out that doing the SELinux MAC checks for mmap() before the DAC checks was causing users and the SELinux policy folks headaches as users were seeing a lot of SELinux AVC denials for the memprotect:mmap_zero permission that would have also been denied by the normal DAC capability checks (CAP_SYS_RAWIO). Example: # cat mmap_test.c #include <stdlib.h> #include <stdio.h> #include <errno.h> #include <sys/mman.h> int main(int argc, char *argv[]) { int rc; void *mem; mem = mmap(0x0, 4096, PROT_READ | PROT_WRITE, MAP_PRIVATE | MAP_ANONYMOUS | MAP_FIXED, -1, 0); if (mem == MAP_FAILED) return errno; printf("mem = %p\n", mem); munmap(mem, 4096); return 0; } # gcc -g -O0 -o mmap_test mmap_test.c # ./mmap_test mem = (nil) # ausearch -m AVC | grep mmap_zero type=AVC msg=audit(...): avc: denied { mmap_zero } for pid=1025 comm="mmap_test" scontext=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023 tcontext=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023 tclass=memprotect This patch corrects things so that when the above example is run by a user without CAP_SYS_RAWIO the SELinux AVC is no longer generated as the DAC capability check fails before the SELinux permission check.

2014-03-07evm: enable key retention service automaticallyDmitry Kasatkin1-2/+3
If keys are not enabled, EVM is not visible in the configuration menu. It may be difficult to figure out what to do unless you really know. Other subsystems as NFS, CIFS select keys automatically. This patch does the same. This patch also removes '(TRUSTED_KEYS=y || TRUSTED_KEYS=n)' dependency, which is unnecessary. EVM does not depend on trusted keys, but on encrypted keys. evm.h provides compile time dependency.

Between checkpatch changes (eg. sizeof) and inconsistencies between Lindent and checkpatch, unfixed checkpatch errors make it difficult to see new errors. This patch fixes them. Some lines with over 80 chars remained unchanged to improve code readability. The "extern" keyword is removed from internal evm.h to make it consistent with internal ima.h.

2014-03-07ima: fix erroneous removal of security.ima xattrDmitry Kasatkin1-2/+4
ima_inode_post_setattr() calls ima_must_appraise() to check if the file needs to be appraised. If it does not then it removes security.ima xattr. With original policy matching code it might happen that even file needs to be appraised with FILE_CHECK hook, it might not be for POST_SETATTR hook. 'security.ima' might be erronously removed. This patch treats POST_SETATTR as special wildcard function and will cause ima_must_appraise() to be true if any of the hooks rules matches. security.ima will not be removed if any of the hooks would require appraisal.

2014-03-07ima: reduce memory usage when a template containing the n field is usedRoberto Sassu2-17/+13
Before this change, to correctly calculate the template digest for the 'ima' template, the event name field (id: 'n') length was set to the fixed size of 256 bytes. This patch reduces the length of the event name field to the string length incremented of one (to make room for the termination character '\0') and handles the specific case of the digest calculation for the 'ima' template directly in ima_calc_field_array_hash_tfm().

2014-03-07ima: restore the original behavior for sending data with ima templateRoberto Sassu3-4/+10
With the new template mechanism introduced in IMA since kernel 3.13, the format of data sent through the binary_runtime_measurements interface is slightly changed. Now, for a generic measurement, the format of template data (after the template name) is: template_len | field1_len | field1 | ... | fieldN_len | fieldN In addition, fields containing a string now include the '\0' termination character. Instead, the format for the 'ima' template should be: SHA1 digest | event name length | event name It must be noted that while in the IMA 3.13 code 'event name length' is 'IMA_EVENT_NAME_LEN_MAX + 1' (256 bytes), so that the template digest is calculated correctly, and 'event name' contains '\0', in the pre 3.13 code 'event name length' is exactly the string length and 'event name' does not contain the termination character. The patch restores the behavior of the IMA code pre 3.13 for the 'ima' template so that legacy userspace tools obtain a consistent behavior when receiving data from the binary_runtime_measurements interface regardless of which kernel version is used.

The 'get_burstcount' function can in some circumstances 'return -EBUSY' which in tpm_stm_i2c_send is stored in an 'u32 burstcnt' thus converting the signed value into an unsigned value, resulting in 'burstcnt' being huge. Changing the type to u32 only does not solve the problem as the signed value is converted to an unsigned in I2C_WRITE_DATA, resulting in the same effect. Thus -> Change type of burstcnt to u32 (the return type of get_burstcount) -> Add a check for the return value of 'get_burstcount' and propagate a potential error.

git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm Pull ACPI and PM fixes and new device IDs from Rafael Wysocki: "These commits, except for one, are regression fixes and the remaining one fixes a divide error leading to a kernel panic. The majority of the regressions fixed here were introduced during the 3.12 cycle, one of them is from this cycle and one is older. Specifics: - VGA switcheroo was broken for some users as a result of the ACPI-based PCI hotplug (ACPIPHP) changes in 3.12, because some previously ignored hotplug events started to be handled. The fix causes them to be ignored again. - There are two more issues related to cpufreq's suspend/resume handling changes from the 3.12 cycle addressed by Viresh Kumar's fixes. - intel_pstate triggers a divide error in a timer function if the P-state information it needs is missing during initialization. This leads to kernel panics on nested KVM clients and is fixed by failing the initialization cleanly in those cases. - PCI initalization code changes during the 3.9 cycle uncovered BIOS issues related to ACPI wakeup notifications (some BIOSes send them for devices that aren't supposed to support ACPI wakeup). Work around them by installing an ACPI wakeup notify handler for all PCI devices with ACPI support. - The Calxeda cpuilde driver's probe function is tagged as __init, which is incorrect and causes a section mismatch to occur during build. Fix from Andre Przywara removes the __init tag from there. - During the 3.12 cycle ACPIPHP started to print warnings about missing _ADR for devices that legitimately don't have it.

2014-01-03ima: remove unneeded size_limit argument from ima_eventdigest_init_common()Roberto Sassu1-8/+6
This patch removes the 'size_limit' argument from ima_eventdigest_init_common(). Since the 'd' field will never include the hash algorithm as prefix and the 'd-ng' will always have it, we can use the hash algorithm to differentiate the two cases in the modified function (it is equal to HASH_ALGO__LAST in the first case, the opposite in the second).

2014-01-03ima: update IMA-templates.txt documentationMimi Zohar1-2/+4
Patch "ima: extend the measurement list to include the file signature" defined a new field called 'sig' and a new template called 'ima-sig'. This patch updates the Documentation/security/IMA-templates.txt.

2014-01-03ima: pass HASH_ALGO__LAST as hash algo in ima_eventdigest_init()Roberto Sassu1-2/+2
Replace the '-1' value with HASH_ALGO__LAST in ima_eventdigest_init() as the called function ima_eventdigest_init_common() expects an unsigned char.

2014-01-03ima: change the default hash algorithm to SHA1 in ima_eventdigest_ng_init()Roberto Sassu1-1/+1
Replace HASH_ALGO__LAST with HASH_ALGO_SHA1 as the initial value of the hash algorithm so that the prefix 'sha1:' is added to violation digests.
