2010-12-16NFS: Replace old NFSv3 encoder functions with xdr_stream-based onesChuck Lever
The naming scheme of the new encoder functions, which follows the NFSv4 XDR encoder functions, is slightly different than the scheme used for the old functions. Rename the functions as a separate step to keep the patches clean. Signed-off-by: Chuck Lever <chuck.lever@oracle.com> Tested-by: J.

2010-12-16NFS: Introduce new-style XDR encoding functions for NFSv3Chuck Lever
We're interested in taking advantage of the safety benefits of xdr_streams. These data structures allow more careful checking for buffer overflow while encoding. More careful type checking is also introduced in the new functions. For efficiency, we also eventually want to be able to pass xdr_streams from call_encode() to all XDR encoding functions, rather than building an xdr_stream in every XDR encoding function in the kernel. To do this means all encoders must be ready to handle a passed-in xdr_stream. The new encoders follow the modern paradigm for XDR encoders: BUG on error, and always return a zero status code. Static helper functions are left without the "inline" directive. This allows the compiler to choose automatically how to optimize these for size or speed.

2010-12-16lockd: Introduce new-style XDR functions for NLMv3Chuck Lever
We'd like to prevent local buffer overflows caused by malicious or broken servers. New xdr_stream style decoders can do that. For efficiency, we also eventually want to be able to pass xdr_streams from call_encode() and call_decode() to all XDR encoding functions, rather than building an xdr_stream in every XDR encoding and decoding function in the kernel. To do all of this, rewrite the XDR encoding and decoding functions in fs/lockd/xdr.c to use xdr_streams. This makes them more or less incompatible with server-side XDR helper functions, so break them out into a separate source file. Static helper functions are left without the "inline" directive. This allows the compiler to choose automatically how to optimize these for size or speed. SHARE-related functionality doesn't seem to be used, as those functions are hiding behind a #define that isn't set anywhere that I can find. And, they've been in there forever (at least as far back as the kernel's git history goes), yet remain unused. Let's take the opportunity to bin them. It should be easy enough for someone to introduce proper XDR functions if at some point SHARE-related NLM functionality is desired. Signed-off-by: Chuck Lever <chuck.lever@oracle.com> Tested-by: J.

2010-12-16lguest: populate initial_page_tableRusty Russell
Two x86 patches broke lguest: 1) v2.6.35-492-g72d7c3b, which changed x86 to use the memblock allocator. In lguest, the host places linear page tables at the top of mem, which used to be enough to get us up to the swapper_pg_dir page tables. With the first patch, the direct mapping tables used that memory: Before: kernel direct mapping tables up to 4000000 @ 7000-1a000 After: kernel direct mapping tables up to 4000000 @ 3fed000-4000000 I initially fixed this by lying about the amount of memory we had, so the kernel wouldn't blatt the lguest boot pagetables (yuk!), but then... 2) v2.6.36-rc8-54-gb40827f, which made x86 boot use initial_page_table. This was initialized in a part of head_32.S which isn't executed by lguest; it is then copied into swapper_pg_dir. So we have to initialize it; and anyway we switch to it before we blatt the old tables, so that fixes the previous damage as well. For the moment, I cut & pasted the code into lguest's boot code, but next merge window I will merge them.

2010-12-16lguest: restore boot speedRusty Russell
lguest is dumb and drops *all* the pagetables for set_pte (which is only used for kernel mapping manipulation, so it's OK without highmem). But it's used a lot in boot, too. As a guest optimization, we suppressed this flushing until the first page switch. Now we have initial_page_table, that happens much earlier, so extend the heuristic to wait until we switch to something other than the swapper_pg_dir or initial_page_table. As measured on my laptop under kvm, this dropped the time-to-mount-root from 48 seconds to 4.3 seconds. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>

2010-12-16nilfs2: fix regression of garbage collection ioctlRyusuke Konishi
On 2.6.37-rc1, garbage collection ioctl of nilfs was broken due to the commit 263d90cefc7d82a0 ("nilfs2: remove own inode hash used for GC"), and leading to filesystem corruption. The patch doesn't queue gc-inodes for log writer if they are reused through the vfs inode cache. Here, gc-inode is the inode which buffers blocks to be relocated on GC. That patch queues gc-inodes in nilfs_init_gcinode() function, but this function is not called when they don't have I_NEW flag. Thus, some of live blocks are wrongly overrode without being moved to new logs. This resolves the problem by moving the gc-inode queueing to an outer function to ensure it's done right.

2010-12-15install_special_mapping skips security_file_mmap check.Tavis Ormandy
The install_special_mapping routine (used, for example, to setup the vdso) skips the security check before insert_vm_struct, allowing a local attacker to bypass the mmap_min_addr security restriction by limiting the available pages for special mappings. bprm_mm_init() also skips the check, and although I don't think this can be used to bypass any restrictions, I don't see any reason not to have the security check. $ uname -m x86_64 $ cat /proc/sys/vm/mmap_min_addr 65536 $ cat install_special_mapping.s section .bss resb BSS_SIZE section .text global _start _start: mov eax, __NR_pause int 0x80 $ nasm -D__NR_pause=29 -DBSS_SIZE=0xfffed000 -f elf -o install_special_mapping.o install_special_mapping.s $ ld -m elf_i386 -Ttext=0x10000 -Tbss=0x11000 -o install_special_mapping install_special_mapping.o $ ./install_special_mapping & [1] 14303 $ cat /proc/14303/maps 0000f000-00010000 r-xp 00000000 00:00 0 [vdso] 00010000-00011000 r-xp 00001000 00:19 2453665 /home/taviso/install_special_mapping 00011000-ffffe000 rwxp 00000000 00:00 0 [stack] It's worth noting that Red Hat are shipping with mmap_min_addr set to 4096.

2010-12-14Input: define separate EVIOCGKEYCODE_V2/EVIOCSKEYCODE_V2Dmitry Torokhov
The desire to keep old names for the EVIOCGKEYCODE/EVIOCSKEYCODE while extending them to support large scancodes was a mistake. While we tried to keep ABI intact (and we succeeded in doing that, programs compiled on older kernels will work on newer ones) there is still a problem with recompiling existing software with newer kernel headers. New kernel headers will supply updated ioctl numbers and kernel will expect that userspace will use struct input_keymap_entry to set and retrieve keymap data. But since the names of ioctls are still the same userspace will happily compile even if not adjusted to make use of the new structure and will start miraculously fail in the field. To avoid this issue let's revert EVIOCGKEYCODE/EVIOCSKEYCODE definitions and add EVIOCGKEYCODE_V2/EVIOCSKEYCODE_V2 so that userspace can explicitly select the style of ioctls it wants to employ.

Cache ownership must be acquired by reading/writing data from the cache line to make cache operation have the desired effect on the SMP MPCore CPU. However, the ownership is never acquired in the v6_dma_inv_range function when cleaning the first line and flushing the last one, in case the address is not aligned to D_CACHE_LINE_SIZE boundary. Fix this by reading/writing data if needed, before performing cache operations. While at it, fix v6_dma_flush_range to prevent RWFO outside the buffer.

Because the nwfpe support is unlikely to be used on new platforms and requires CONFIG_OABI_COMPAT, which is not generally used with ARMv7+, we shouldn't expect to build nwfpe support into a Thumb-2 kernel. At present, nwfpe contains assembly code which isn't Thumb-2 compatible, and for now it doesn't appear useful to port this code. All ARMv7-A/R platforms necessarily have VFPv3 hardware floating- point natively, making emulation unnecessary.

2010-12-14ARM: 6533/1: Thumb-2: Make CONFIG_THUMB2_KERNEL depend on !CPU_V6Dave Martin
This makes sense, because Thumb-2 code can't execute on plain ARMv6 processors. This will avoid accidentally configuring a broken kernel where the config otherwise would allow multiple architecture versions to coexist in the same kernel. Not adding !CPU_V5 etc., because the chance of anyone trying to put v5 and v7 in the same kernel is low, and I'm not aware of any mach which can do this. These could be added later if it matters. Note that the rules may need to be refined if support for the ARM1156J(F)-S processor is later added to the kernel, since this processor supports the rare ARMv6T2 extensions, which add support for Thumb-2 and a few other ARMv7 features.
