ext4_ext_migrate() calls ext4_new_inode() and passes 0 instead of a pointer to a struct qstr. This patch uses NULL, to make it obvious to the caller that this was a pointer. Signed-off-by: NEric Paris <eparis@redhat.com> Signed-off-by: N"Theodore Ts'o" <tytso@mit.edu>

d_path() returns an ERR_PTR and it doesn't return NULL. This is in ext4_error_file() and no one actually calls ext4_error_file(). Signed-off-by: NDan Carpenter <error27@gmail.com>

ext4_issue_discard is supposed to be helper for calling discard, however in case that underlying device does not support discard it prints out the warning message and clears the DISCARD t_mount_opt flag. Since it can be (and is) used by others, it should not do anything and let the caller to handle the error case. This commit removes warning message and flag setting from ext4_issue_discard and use it just in place where it is really needed (release_blocks_on_commit). FITRIM ioctl should not set any flags nor it should print out warning messages, so get rid of the warning as well. Signed-off-by: NLukas Czerner <lczerner@redhat.com>

When determining last group through ext4_get_group_no_and_offset() the result may be wrong in cases when range->start and range-len are too big, because it may overflow when summing up those two numbers. Fix that by checking range->len and limit its value to ext4_blocks_count(). This commit was tested by myself with expected result. Signed-off-by: NLukas Czerner <lczerner@redhat.com>

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.
