2015-01-07ARM: 8253/1: mm: use phys_addr_t type in map_lowmem() for kernel mem regionGrygorii Strashko
Now local variables kernel_x_start and kernel_x_end defined using 'unsigned long' type which is wrong because they represent physical memory range and will be calculated wrongly if LPAE is enabled. As result, all following code in map_lowmem() will not work correctly. For example, Keystone 2 boot is broken because kernel_x_start == 0x0000 0000 kernel_x_end == 0x0080 0000 instead of kernel_x_start == 0x0000 0008 0000 0000 kernel_x_end == 0x0000 0008 0080 0000 and as result whole low memory will be mapped with MT_MEMORY_RW permissions by code (start > kernel_x_end): } else if (start >= kernel_x_end) { map.pfn = __phys_to_pfn(start); map.virtual = __phys_to_virt(start); map.length = end - start; map.type = MT_MEMORY_RW; create_mapping(&map); } Hence, fix it by using phys_addr_t type for variables kernel_x_start and kernel_x_end.

2015-01-07ARM: 8249/1: mm: dump: don't skip regionsMark Rutland
Currently the arm page table dumping code starts dumping page tables from USER_PGTABLES_CEILING. This is unnecessary for skipping any entries related to userspace as the swapper_pg_dir does not contain such entries, and results in a couple of unfortuante side effects. Firstly, any kernel mappings which might exist below USER_PGTABLES_CEILING will not be accounted in the dump output. This masks any entries erroneously created below this address. Secondly, if the final page table entry walked is part of a valid mapping the page table dumping code will not log the region this entry is part of, as the final note_page call in walk_pgd will trigger an early return when 0 < USER_PGTABLES_CEILING. Luckily this isn't seen on contemporary systems as they typically don't have enough RAM to extend the linear mapping right to the end of the address space. Due to the way addr is constructed in the walk_* functions, it can never be less than USER_PGTABLES_CEILING when walking the page tables, so it is not necessary to avoid dereferencing invalid table addresses. The existing checks for st->current_prot and st->marker[1].start_address are sufficient to ensure we will not print and/or dereference garbage when trying to log information. This patch removes both problematic uses of USER_PGTABLES_CEILING from the arm page table dumping code, preventing both of these issues. We will now report any low mappings, and the final note_page call will not return early, ensuring all regions are logged.

2015-01-07rpc: fix xdr_truncate_encode to handle buffer ending on page boundaryJ. Bruce Fields
A struct xdr_stream at a page boundary might point to the end of one page or the beginning of the next, but xdr_truncate_encode isn't prepared to handle the former. This can cause corruption of NFSv4 READDIR replies in the case that a readdir entry that would have exceeded the client's dircount/maxcount limit would have ended exactly on a 4k page boundary. You're more likely to hit this case on large directories. Other xdr_truncate_encode callers are probably also affected.

2015-01-07arm64: Correct __NR_compat_syscalls for bpfMark Rutland
Commit 97b56be10352a70c (arm64: compat: Enable bpf syscall) made the usual mistake of forgetting to update __NR_compat_syscalls. Due to this, when el0_sync_compat calls el0_svc_naked, the test against sc_nr (__NR_compat_syscalls) will fail, and we'll call ni_sys, returning -ENOSYS to userspace. This patch bumps __NR_compat_syscalls appropriately, enabling the use of the bpf syscall from compat tasks. Due to the reorganisation of unistd{,32}.h as part of commit f3e5c847ec3d12b4 (arm64: Add __NR_* definitions for compat syscalls) it is not currently possible to include both headers and sanity-check the value of __NR_compat_syscalls at build-time to prevent this from happening again.

2015-01-06mm: propagate error from stack expansion even for guard pageLinus Torvalds
Jay Foad reports that the address sanitizer test (asan) sometimes gets confused by a stack pointer that ends up being outside the stack vma that is reported by /proc/maps. This happens due to an interaction between RLIMIT_STACK and the guard page: when we do the guard page check, we ignore the potential error from the stack expansion, which effectively results in a missing guard page, since the expected stack expansion won't have been done. And since /proc/maps explicitly ignores the guard page (commit d7824370e263: "mm: fix up some user-visible effects of the stack guard page"), the stack pointer ends up being outside the reported stack area. This is the minimal patch: it just propagates the error. It also effectively makes the guard page part of the stack limit, which in turn measn that the actual real stack is one page less than the stack limit. Let's see if anybody notices. We could teach acct_stack_growth() to allow an extra page for a grow-up/grow-down stack in the rlimit test, but I don't want to add more complexity if it isn't needed.
