This patch fixes kernel Oops because of wrong common_audit_data type
in smack_inode_unlink() and smack_inode_rmdir().
When SMACK security module is enabled and SMACK logging is on (/smack/logging
is not zero) and you try to delete the file which
1) you cannot delete due to SMACK rules and logging of failures is on
or
2) you can delete and logging of success is on,
you will see following:
Unable to handle kernel NULL pointer dereference at virtual address 000002d7
[<...>] (strlen+0x0/0x28)
[<...>] (audit_log_untrustedstring+0x14/0x28)
[<...>] (common_lsm_audit+0x108/0x6ac)
[<...>] (smack_log+0xc4/0xe4)
[<...>] (smk_curacc+0x80/0x10c)
[<...>] (smack_inode_unlink+0x74/0x80)
[<...>] (security_inode_unlink+0x2c/0x30)
[<...>] (vfs_unlink+0x7c/0x100)
[<...>] (do_unlinkat+0x144/0x16c)
The function smack_inode_unlink() (and smack_inode_rmdir()) need
to log two structures of different types. First of all it does:
smk_ad_init(&ad, __func__, LSM_AUDIT_DATA_DENTRY);
smk_ad_setfield_u_fs_path_dentry(&ad, dentry);
This will set common audit data type to LSM_AUDIT_DATA_DENTRY
and store dentry for auditing (by function smk_curacc(), which in turn calls
dump_common_audit_data(), which is actually uses provided data and logs it).
/*
* You need write access to the thing you're unlinking
*/
rc = smk_curacc(smk_of_inode(ip), MAY_WRITE, &ad);
if (rc == 0) {
/*
* You also need write access to the containing directory
*/
Then this function wants to log anoter data:
smk_ad_setfield_u_fs_path_dentry(&ad, NULL);
smk_ad_setfield_u_fs_inode(&ad, dir);
The function sets inode field, but don't change common_audit_data type.
rc = smk_curacc(smk_of_inode(dir), MAY_WRITE, &ad);
}
So the dump_common_audit() function incorrectly interprets inode structure
as dentry, and Oops will happen.
This patch reinitializes common_audit_data structures with correct type.
Also I removed unneeded
smk_ad_setfield_u_fs_path_dentry(&ad, NULL);
initialization, because both dentry and inode pointers are stored
in the same union.

I am including the enhancement for mount to only trigger requests of
filesystem modules here instead of delaying this for the 3.10 merge
window because it is both trivial and the kind of change that tends to
bit-rot if left untouched for two months."

There is a more complete atmel patch-series out by Nick Dyer that fixes
this and other things, but in the meantime this is the minimal thing to
get the touchscreen going on (at least my) Pixel Chromebook.
Not that I want my dirty fingers near that beautiful screen, but it
seems that a non-initialized touchscreen will also end up being a
constant wakeup source, so you have to disable it to go to sleep. And
it's easier to just fix the initialization sequence.

Update proc_ns_follow_link to use nd_jump_link instead of just
manually updating nd.path.dentry.
This fixes the BUG_ON(nd->inode != parent->d_inode) reported by Dave
Jones and reproduced trivially with mkdir /proc/self/ns/uts/a.
Sigh it looks like the VFS change to require use of nd_jump_link
happend while proc_ns_follow_link was baking and since the common case
of proc_ns_follow_link continued to work without problems the need for
making this change was overlooked.

This same driver can be used by atmel based touchscreens and touchpads
(buttonpads). Platform data may specify a device is a touchpad
using the is_tp flag.
This will cause the driver to perform some touchpad specific
initializations, such as:
* register input device name "Atmel maXTouch Touchpad" instead of
Touchscreen.
* register BTN_LEFT & BTN_TOOL_* event types.
* register axis resolution (as a fixed constant, for now)
* register BUTTONPAD property
* process GPIO buttons using reportid T19
Input event GPIO mapping is done by the platform data key_map array.
key_map[x] should contain the KEY or BTN code to send when processing
GPIOx from T19. To specify a GPIO as not an input source, populate
with KEY_RESERVED, or 0.

idr_find(), idr_remove() and idr_replace() used to silently ignore the
sign bit and perform lookup with the rest of the bits. The weird behavior
has been changed such that negative IDs are treated as invalid. As the
behavior change was subtle, WARN_ON_ONCE() was added in the hope of
determining who's calling idr functions with negative IDs so that they can
be examined for problems.
Up until now, all two reported cases are ID number coming directly from
userland and getting fed into idr_find() and the warnings seem to cause
more problems than being helpful. Drop the WARN_ON_ONCE()s.

Commit ac24c2204a ("drm/tegra: Use generic
HDMI infoframe helpers") added "select DRM_HDMI" to the DRM_TEGRA
Kconfig entry. But there is no Kconfig symbol named DRM_HDMI. The select
statement for that symbol is a nop. Drop it.
What was needed to use HDMI functionality was to select HDMI (which this
entry already did through depending on DRM) and to include linux/hdmi.h
(which this commit also did).

Renesas boards were consistently defaulting to the 1024x768 resolution,
regardless of the native resolution of the monitor plugged in. It was
determined that the EDID of the monitor was not being read. Since the
DAC is a shared line, in order to read from or write to it we must take
control of the DAC clock. This can be done by setting the proper
register to one.
This bug fix sets the register MGA1064_GEN_IO_CTL2 to one. The DAC
control line can be used to determine whether or not a new monitor has
been plugged in. But since the hotplug feature is not one we will
support, it has been decided to simply leave the register set to one.

A monitor or a user could request a resolution greater than the
available VRAM for the backing framebuffer. This change checks the
required framebuffer size against the max VRAM size and rejects modes
if they are too big. This change can also remove a mode request passed
in via the video= parameter.

kernel_map_sync_memtype() is called from a variety of contexts. The
pat.c code that calls it seems to ensure that it is not called for
non-ram areas by checking via pat_pagerange_is_ram(). It is important
that it only be called on the actual identity map because there *IS*
no map to sync for highmem pages, or for memory holes.
The ioremap.c uses are not as careful as those from pat.c, and call
kernel_map_sync_memtype() on PCI space which is in the middle of the
kernel identity map _range_, but is not actually mapped.
This patch adds a check to kernel_map_sync_memtype() which probably
duplicates some of the checks already in pat.c. But, it is necessary
for the ioremap.c uses and shouldn't hurt other callers.
I have reproduced this bug and this patch fixes it for me and the
original bug reporter:
