proc doesn't use "associate pointer with id" feature of IDR, so switch
to IDA.NOTE, NOTE, NOTE:
Do not apply if release_inode_number() still mantions MAX_ID_MASK!Signed-off-by: Alexey Dobriyan
Signed-off-by: Al Viro -
Id which proc gets from IDR for inode number and id which proc removes
from IDR do not match. E.g. 0x11a transforms into 0x8000011a.Which stayed unnoticed for a long time because, surprise, idr_remove()
masks out that high bit before doing anything.All of this due to "| ~MAX_ID_MASK" in release_inode_number().
I still don't understand how it's supposed to work, because "| ~MASK"
is not an inversion for "& MAX" operation.So, use just one nice, working addition. Make start offset unsigned int,
while I'm at it. It's longness is not used anywhere.Signed-off-by: Alexey Dobriyan

* new helper: vfs_quota_on_path(); equivalent of vfs_quota_on() sans the
pathname resolution.
* callers of vfs_quota_on() that do their own pathname resolution and
checks based on it are switched to vfs_quota_on_path(); that way we
avoid the races.
* reiserfs leaked dentry/vfsmount references on several failure exits.Signed-off-by: Al Viro

for July 17: early crash on x86-64)
SELinux needs MAY_APPEND to be passed down to the security hook.
Otherwise, we get permission denials when only append permission is
granted by policy even if the opening process specified O_APPEND.
Shows up as a regression in the ltp selinux testsuite, fixed by
this patch.Signed-off-by: Stephen Smalley

The iov_iter_advance() function would look at the iov->iov_len entry
even though it might have iterated over the whole array, and iov was
pointing past the end. This would cause DEBUG_PAGEALLOC to trigger a
kernel page fault if the allocation was at the end of a page, and the
next page was unallocated.The quick fix is to just change the order of the tests: check that there
is any iovec data left before we check the iov entry itself.Thanks to Alexey Dobriyan for finding this case, and testing the fix.

We zero-fill them like we are supposed to, and that's all fine. It's
only an error if the 'romfs_copyfrom()' routine isn't able to fill the
data that is supposed to be there.Most of the patch is really just re-organizing the code a bit, and using
separate variables for the error value and for how much of the page we
actually filled from the filesystem.Reported-and-tested-by: Chris Fester
