Clemens points out that we need to use compat_ptr() in order to safely
cast from u64 to addresses of a 32-bit usermode client.
Before, our conversion went wrong
- in practice if the client cast from pointer to integer such that
sign-extension happened, (libraw1394 and libdc1394 at least were not
doing that, IOW were not affected)
or
- in theory on s390 (which doesn't have FireWire though) and on the
tile architecture, regardless of what the client does.
The bug would usually be observed as the initial get_info ioctl failing
with "Bad address" (EFAULT).

We have two sources of information about panel capabilities on mobile
radeon - the BIOS, which gives us a native mode, and the panel's preferred
mode. In theory these two will always match, but there's some corner cases
where the BIOS hasn't been fully initialised and so the native mode in it
ends up with default values. However, if we get a panel with reasonable
EDID, it's probably the case that the panel's preferred mode does actually
represent the panel capabilities. This patch handles that case by replacing
the native mode with the panel's preferred mode if the resolutions don't
match. Systems without a valid internal panel EDID will still use the BIOS
native mode.

enabled, credits are needed to create the selinux xattr as well.
Overrunning the reservation will result in an OOPS in

The patch http://lkml.org/lkml/2003/7/13/226 introduced an RLIMIT_NPROC
check in set_user() to check for NPROC exceeding via setuid() and
similar functions.
Before the check there was a possibility to greatly exceed the allowed
number of processes by an unprivileged user if the program relied on
rlimit only. But the check created new security threat: many poorly
written programs simply don't check setuid() return code and believe it
cannot fail if executed with root privileges. So, the check is removed
in this patch because of too often privilege escalations related to
buggy programs.
The NPROC can still be enforced in the common code flow of daemons
spawning user processes. Most of daemons do fork()+setuid()+execve().
The check introduced in execve() (1) enforces the same limit as in
setuid() and (2) doesn't create similar security issues.
Neil Brown suggested to track what specific process has exceeded the
limit by setting PF_NPROC_EXCEEDED process flag. With the change only
this process would fail on execve(), and other processes' execve()
behaviour is not changed.
Solar Designer suggested to re-check whether NPROC limit is still
exceeded at the moment of execve(). If the process was sleeping for
days between set*uid() and execve(), and the NPROC counter step down
under the limit, the defered execve() failure because NPROC limit was
exceeded days ago would be unexpected. If the limit is not exceeded
anymore, we clear the flag on successful calls to execve() and fork().
The flag is also cleared on successful calls to set_user() as the limit
was exceeded for the previous user, not the current one.
Similar check was introduced in -ow patches (without the process flag).
v3 - clear PF_NPROC_EXCEEDED on successful calls to set_user().

Set security descriptor using path name instead of a file handle.
We can't be sure that the file handle has adequate permission to

Function set_cifs_acl_by_fid() has been removed since we can't be
sure how a file was opened for writing, a valid request can fail
if the file was not opened with two above mentioned permissions.
We could have opted to add on WRITE_DAC and WRITE_OWNER permissions
to file opens and then use that file handle but adding addtional
permissions such as WRITE_DAC and WRITE_OWNER could cause an
any open to fail.
And it was incorrect to look for read file handle to set a
