This patch allows hostfs_setattr() to work on unlinked open files by calling set_attr() (the userspace part) with the inode's fd. Without this, applications that depend on doing attribute changes to unlinked open files will fail. It works by using the fd versions instead of the path ones (for example fchmod() instead of chmod(), fchown() instead of chown()) when an fd is available. Signed-off-by:

This patch is add white list into modpost.c for some functions and ia64's section to fix section mismatchs. sparse_index_alloc() and zone_wait_table_init() calls bootmem allocator at boot time, and kmalloc/vmalloc at hotplug time. If config memory hotplug is on, there are references of bootmem allocater(init text) from them (normal text). This is cause of section mismatch. Bootmem is called by many functions and it must be used only at boot time. I think __init of them should keep for section mismatch check. So, I would like to register sparse_index_alloc() and zone_wait_table_init() into white list. In addition, ia64's .machvec section is function table of some platform dependent code. It is mixture of .init.text and normal text. These reference of __init functions are valid too. Signed-off-by:

There are two problems with the existing redzone implementation. Firstly, it's causing misalignment of structures which contain a 64-bit integer, such as netfilter's 'struct ipt_entry' -- causing netfilter modules to fail to load because of the misalignment. (In particular, the first check in net/ipv4/netfilter/ip_tables.c::check_entry_size_and_hooks()) On ppc32 and sparc32, amongst others, __alignof__(uint64_t) == 8. With slab debugging, we use 32-bit redzones. And allocated slab objects aren't sufficiently aligned to hold a structure containing a uint64_t. By _just_ setting ARCH_KMALLOC_MINALIGN to __alignof__(u64) we'd disable redzone checks on those architectures. By using 64-bit redzones we avoid that loss of debugging, and also fix the other problem while we're at it. When investigating this, I noticed that on 64-bit platforms we're using a 32-bit value of RED_ACTIVE/RED_INACTIVE in the 64-bit memory location set aside for the redzone. Which means that the four bytes immediately before or after the allocated object at 0x00,0x00,0x00,0x00 for LE and BE machines, respectively. Which is probably not the most useful choice of poison value. One way to fix both of those at once is just to switch to 64-bit redzones in all cases. Signed-off-by:

The newly merged SLUB allocator patches had been generated before the removal of "struct subsystem", and ended up applying fine, but wouldn't build based on the current tree as a result. Fix up that merge error - not that SLUB is likely really ready for showtime yet, but at least I can fix the trivial stuff. Signed-off-by: -

Convert an arch that does not currently implement sub-jiffy timekeeping to use the generic timekeeping code. v850 looks like it has some intent to implement sub-jiffy timekeeping, so it may not yet be appropriate to try to convert, but I figured I'd get the maintainer's input and submit the patch for comment.

With the current timekeeping, !CONFIG_UML_REAL_TIME_CLOCK has inconsistent behavior. Previously, gettimeofday could be (and was) isolated from the clock ticking. Now, it's not, so when CONFIG_UML_REAL_TIME_CLOCK is disabled, gettimeofday must progress in lockstep with the clock, making it fully virtual. Signed-off-by:

More trimming of the page fault path. Permissions are passed around in a single int rather than one bit per int. The permission values are copied from libc so that they can be passed to mmap and mprotect without any further conversion. The register sets used by do_syscall_stub and copy_context_skas0 are initialized once, at boot time, rather than once per call. wait_stub_done checks whether it is getting the signals it expects by comparing the wait status to a mask containing bits for the signals of interest rather than comparing individually to the signal numbers. It also has one check for a wait failure instead of two. The caller is expected to do the initial continue of the stub. This gets rid of an argument and some logic. The fname argument is gone, as that can be had from a stack trace. user_signal() is collapsed into userspace() as it is basically one or two lines of code afterwards. The physical memory remapping stuff is gone, as it is unused. flush_tlb_page is inlined. Signed-off-by:

Give the page fault code a specialized path. There is only one page to look at, so there's no point in going into the general page table walking code. There's only going to be one host operation, so there are no opportunities for merging. So, we go straight to the pte we want, figure out what needs doing, and do it. While I was in here, I fixed the wart where the address passed to unmap was a void *, but an unsigned long to map and protect. This gives me just under 10% on a kernel build. Signed-off-by:

Code running on the initial UML stack can't receive or process signals since current must be valid when IRQs are handled, and there is no current for this stack. So, instead of using UML_LONGJMP and UML_SETJMP, which are careful to save and restore signal state, and, as a side-effect, handle any deferred signals, start_idle_thread must use the bare equivalents, which don't do anything with signals.
