It's used only to pass the length of symlink body to autofs4_get_inode() in autofs4_dir_symlink(). We can bloody well set inode->i_size in autofs4_dir_symlink() directly and be done with that. Acked-by: NIan Kent <raven@themaw.net> Signed-off-by: NAl Viro <viro@zeniv.linux.org.uk>

There is a ref count problem in fs/namei.c:do_lookup(). When walking in ref-walk mode, if follow_managed() returns a fail we need to drop dentry and possibly vfsmount.

The initialization condition in fs/autofs4/expire.c:get_next_positive_dentry() appears to be incorrect. If prev == NULL I believe that root should be returned. Further down, at the current dentry check for it being simple_positive() it looks like the d_lock for dentry p should be dropped instead of dentry ret, otherwise when p is assinged to ret we end up with no lock on p and a lost lock on ret, which leads to a deadlock.

This patch comes from "Forced readonly mounts on errors" ideas. As we know, this is the first step in being more fault tolerant of disk corruptions instead of just using BUG() statements. The major content: - add a framework for generating errors that should result in filesystems going readonly. - keep FS state in disk super block. - make sure that all of resource will be freed and released at umount time. - make sure that fter FS is forced readonly on error, there will be no more disk change before FS is corrected. For this, we should stop write operation. After this patch is applied, the conversion from BUG() to such a framework can happen incrementally.

由 Artem Bityutskiy 提交于
This patch fixes the mtdpart bug which allows users reading OOB past the end of the partition. This happens because 'part_read_oob()' allows reading multiple OOB areas in one go, and mtdparts does not validate the OOB length in the request. Although there is such check in 'nand_do_read_oob()' in nand_base.c, but it checks that we do not read past the flash chip, not the partition, because in nand_base.c we work with the whole chip (e.g., mtd->size in nand_base.c is the size of the whole chip). So this check cannot be done correctly in nand_base.c and should be instead done in mtdparts.c. This problem was reported by Jason Liu <r64343@freescale.com> and reproduced with nandsim: $ modprobe nandsim first_id_byte=0x20 second_id_byte=0xaa third_id_byte=0x00 \ fourth_id_byte=0x15 parts=0x400,0x400 $ modprobe nandsim mtd_oobtest.ko dev=0 $ dmesg = snip = mtd_oobtest: attempting to read past end of device mtd_oobtest: an error is expected... mtd_oobtest: error: read past end of device = snip = mtd_oobtest: finished with 2 errors Reported-by: NJason Liu <liu.h.jason@gmail.com> Signed-off-by: NArtem Bityutskiy <Artem.Bityutskiy@nokia.com> Signed-off-by: NDavid Woodhouse <David.Woodhouse@intel.com>
