2015-01-08perf hists browser: Fix segfault when showing callchainNamhyung Kim1-1/+1
When perf report on TUI shows callchain it checks first node has siblings to determine whether it needs to print percentage value. But it missed a case that first node is NULL.

2015-01-08perf hists: Fix children sort key behaviorNamhyung Kim2-32/+35
When perf report --children resorts output fields, it tries to put caller above the callee. But this was only meaningful for a same thread and doing this requires callchain enabled. So fix its check before comparing the callchain depth. This also changes the hist accumulation tests: In test 3, xmalloc in bash thread should be above than other perf threads due to alphabetical order of comm string. Also it's under page_fault in bash thread since alphabetical order of dso name. The sys_perf_event_open in perf thread is put on the last line since it's self overhead is 0. In test 4, the sys_perf_event_open is put above other perf entries that have same children overhead since its callchain depth is smaller.

2015-01-08arm64/efi: add missing call to early_ioremap_reset()Ard Biesheuvel2-1/+2
The early ioremap support introduced by patch bf4b558eba92 ("arm64: add early_ioremap support") failed to add a call to early_ioremap_reset() at an appropriate time. Without this call, invocations of early_ioremap etc. that are done too late will go unnoticed and may cause corruption. This is exactly what happened when the first user of this feature was added in patch f84d02755f5a ("arm64: add EFI runtime services"). The early mapping of the EFI memory map is unmapped during an early initcall, at which time the early ioremap support is long gone. Fix by adding the missing call to early_ioremap_reset() to setup_arch(), and move the offending early_memunmap() to right after the point where the early mapping of the EFI memory map is last used.

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 Rutland1-7/+2
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 Fields1-3/+3
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 Rutland1-1/+1
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.

While looking at hch's recent conversion to drop the MSG_*_TAG definitions, I noticed a long standing bug in vhost-scsi where the VIRTIO_SCSI_S_* attribute definitions where incorrectly being passed directly into target_submit_cmd_map_sgls().

2015-01-06mm: propagate error from stack expansion even for guard pageLinus Torvalds2-3/+3
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.

2015-01-06selftests/exec: allow shell return code of 126David Drysdale1-6/+13
When the shell fails to invoke a script because its path name is too long (ENAMETOOLONG), most shells return 127 to indicate command not found. However, some systems report 126 (which POSIX suggests should indicate a non-executable file) for this case, so allow that too.
