2014-08-21HID: logitech: fix bounds checking on LED report sizeJiri Kosina1-1/+1
The check on report size for REPORT_TYPE_LEDS in logi_dj_ll_raw_request() is wrong; the current check doesn't make any sense -- the report allocated by HID core in hid_hw_raw_request() can be much larger than DJREPORT_SHORT_LENGTH, and currently logi_dj_ll_raw_request() doesn't handle this properly at all. Fix the check by actually trimming down the report size properly if it is too large.

2014-08-20perf: Handle compat ioctlPawel Moll1-1/+22
When running a 32-bit userspace on a 64-bit kernel (eg. i386 application on x86_64 kernel or 32-bit arm userspace on arm64 kernel) some of the perf ioctls must be treated with special care, as they have a pointer size encoded in the command. For example, PERF_EVENT_IOC_ID in 32-bit world will be encoded as 0x80042407, but 64-bit kernel will expect 0x80082407. In result the ioctl will fail returning -ENOTTY.

Currently when run on an APM platform the ARMv8 defconfig has no viable options for rootfs other than ramdisk which is rather limiting. Since we already have both SATA and the bits needed for NFS root enabled we just need to enable the relevant drivers so do that, helping enable direct testing of upstream.

2014-08-19arm64: align randomized TEXT_OFFSET on 4 kB boundaryArd Biesheuvel2-5/+5
When booting via UEFI, the kernel Image is loaded at a 4 kB boundary and the embedded EFI stub is executed in place. The EFI stub relocates the Image to reside TEXT_OFFSET bytes above a 2 MB boundary, and jumps into the kernel proper. In AArch64, PC relative symbol references are emitted using adrp/add or adrp/ldr pairs, where the offset into a 4 kB page is resolved using a separate :lo12: relocation. This implicitly assumes that the code will always be executed at the same relative offset with respect to a 4 kB boundary, or the references will point to the wrong address. This means we should link the kernel at a 4 kB aligned base address in order to remain compatible with the base address the UEFI loader uses when doing the initial load of Image. So update the code that generates TEXT_OFFSET to choose a multiple of 4 kB. At the same time, update the code so it chooses from the interval [0..2MB) as the author originally intended.

2014-08-19isofs: Fix unbounded recursion when processing relocated directoriesJan Kara3-22/+55
We did not check relocated directory in any way when processing Rock Ridge 'CL' tag. Thus a corrupted isofs image can possibly have a CL entry pointing to another CL entry leading to possibly unbounded recursion in kernel code and thus stack overflow or deadlocks (if there is a loop created from CL entries). Fix the problem by not allowing CL entry to point to a directory entry with CL entry (such use makes no good sense anyway) and by checking whether CL entry doesn't point to itself.
