Using %pV reduces the number of printk calls and eliminates any possible message interleaving from other printk calls. In function __ext4_grp_locked_error also added KERN_CONT to some printks. Signed-off-by: Joe Perches <joe@perches.com> Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>

When nanosecond timestamp resolution isn't supported on an ext4 partition (inode size = 128), stat() appears to be returning uninitialized garbage in the nanosecond component of timestamps. EXT4_INODE_GET_XTIME should zero out tv_nsec when EXT4_FITS_IN_INODE evaluates to false.

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.

This gets caught by the new sanity check code. Instead of the slash use a different symbol. This was originally found by Major Lee who proposed a rather more complex patch which changed the name according to the chip type. On the basis that we are in a late -rc and making Linus grumpy isn't always a good idea (however fun) this is a simple alternative.

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.
