viafb: update fix before calculating depth As the depth calculation depends on information in fix it is saner to do the update first. No runtime change expected as the value visual in fix used never changes to MONO. Signed-off-by: Florian Tobias Schandinat <FlorianSchandinat@gmx.de> Cc: Joseph Chan <JosephChan@via.com.tw>

viafb: PLL value cleanup This is a big change of how PLL values are handled on the road to dynamic PLL value generation. The table was converted automatically in the relevant parameters for frequency generation. Sadly there were some bits set whose meaning is unknown. Those differences are documented but ignored as the unichrome code implies that they are not important (a big thanks to Luc for his amazing work). The PLL values for 31490000 and 133308000 are deleted as they were more than 5% off and not used anyway. The values for CX700@60466000 and VX855@153920000 are corrected as they were wrong and easily correctable as enough correct values was available because CX700 and VX855 support the same values only with a little difference in hardware format. All remaining values are not more than 2% off. Additionally the surrounding code is changed as needed especially the byte order of the values written to hardware to allow nicer conversion functions. This is mostly a change preparing for dynamic PLL generation and the two corrected values aside no runtime change is expected.

viafb: simplify lcd size "detection" Remove all occurences of get_lcd_size_method as only the values GET_LCD_SIZE_BY_VGA_BIOS and GET_LCD_SIZE_BY_USER_SETTING were used which had the identical code so there is no need to make things look more complicated than they actually are. Just a bit of of cleanup, really no regressions expected. Signed-off-by: Florian Tobias Schandinat <FlorianSchandinat@gmx.de> Cc: Joseph Chan <JosephChan@via.com.tw>

viafb: fix PCI table This patch fixes an oddity in the device table where the P4M890 ID was assigned with the enumeration value of CN700 which itself was missing. This is a regression introduced by "viafb: make viafb a first-class citizen using pci_driver" While at it reorder the table to reflect the order of the enumeration values.

viafb: add lcd scaling support for some IGPs These IGPs should also support lcd scaling but likely this switch was missed when adding support for them. Fix it, allowing lcd scaling on CN750, VX800 and VX855. At least this improves the situation for VX855. (there seems to be another scaling unrelated bug somewhere) Signed-off-by: Florian Tobias Schandinat <FlorianSchandinat@gmx.de> Cc: Joseph Chan <JosephChan@via.com.tw>

Fix the security problem in the CIFS filesystem DNS lookup code in which a malicious redirect could be installed by a random user by simply adding a result record into one of their keyrings with add_key() and then invoking a CIFS CFS lookup [CVE-2010-2524]. This is done by creating an internal keyring specifically for the caching of DNS lookups. To enforce the use of this keyring, the module init routine creates a set of override credentials with the keyring installed as the thread keyring and instructs request_key() to only install lookup result keys in that keyring. The override is then applied around the call to request_key(). This has some additional benefits when a kernel service uses this module to request a key: (1) The result keys are owned by root, not the user that caused the lookup. (2) The result keys don't pop up in the user's keyrings. (3) The result keys don't come out of the quota of the user that caused the lookup. The keyring can be viewed as root by doing cat /proc/keys: 2a0ca6c3 I----- 1 perm 1f030000 0 0 keyring .dns_resolver: 1/4 It can then be listed with 'keyctl list' by root. # keyctl list 0x2a0ca6c3 1 key in keyring: 726766307: --alswrv 0 0 dns_resolver: foo.bar.com Signed-off-by: David Howells <dhowells@redhat.com> Reviewed-and-Tested-by: Jeff Layton <jlayton@redhat.com> Acked-by: Steve French <smfrench@gmail.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

In the CONFIG_AUDITSYSCALL fast-path for x86 64-bit system calls, we can pass a bad return value and/or error indication for the system call to audit_syscall_exit(). This happens when TIF_NEED_RESCHED was set as the system call returned, so we went out to schedule() and came back to the exit-audit fast-path. The fix is to reload the user return value register from the pt_regs before using it for audit_syscall_exit(). Both the 32-bit kernel's fast path and the 64-bit kernel's 32-bit system call fast paths work slightly differently, so that they always leave the fast path entirely to reschedule and don't return there, so they don't have the analogous bugs.

Immediately following an exit from the kdb shell the kgdb_connected variable should be set to zero, unless there are breakpoints planted.

In the process of merging kdb to the mainline, the kdb lsmod command stopped printing the base load address of kernel modules.

The gdbserial protocol handler should return an empty packet instead of an error string when ever it responds to a command it does not implement. The problem cases come from a debugger client sending qTBuffer, qTStatus, qSearch, qSupported. The incorrect response from the gdbstub leads the debugger clients to not function correctly. Recent versions of gdb will not detach correctly as a result of this behavior. Signed-off-by: Jason Wessel <jason.wessel@windriver.com> Signed-off-by: Dongdong Deng <dongdong.deng@windriver.com>

We only add/remove crtcs at driver load, you cannot remove when the GPU is running a CS packet since the fd is open, when GPU hotplugging on radeons actually is needed all this locking needs a review and I've started re-working kms core locking to deal with this better. But for now avoid long delays in CS processing when hotplug detect is happening in a different thread. this fixes a regression introduced with hotplug detection.

The Nokia RX51 board code (arch/arm/mach-omap2/board-rx51-peripherals.c) defines a key map for the matrix keypad keyboard. The hardware seems to use all of the 8 rows and 8 columns of the keypad, although not all possible locations are used. The TWL4030 supports keypads with at most 8 rows and 8 columns. Most keys are defined with a row and column number between 0 and 7, except KEY(0xff, 2, KEY_F9), KEY(0xff, 4, KEY_F10), KEY(0xff, 5, KEY_F11), which represent keycodes that should be emitted when entire row is connected to the ground. since the driver handles this case as if we had an extra column in the key matrix. Unfortunately we do not allocate enough space and end up owerwriting some random memory.

The kernel's math-emu code contains a macro _FP_FROM_INT() which is used to convert an integer to a raw normalized floating-point value. It does this basically in three steps: 1. Compute the exponent from the number of leading zero bits. 2. Downshift large fractions to put the MSB in the right position for normalized fractions. 3. Upshift small fractions to put the MSB in the right position. There is an boundary error in step 2, causing a fraction with its MSB exactly one bit above the normalized MSB position to not be downshifted. This results in a non-normalized raw float, which when packed becomes a massively inaccurate representation for that input. The impact of this depends on a number of arch-specific factors, but it is known to have broken emulation of FXTOD instructions on UltraSPARC III, which was originally reported as GCC bug 44631 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=44631>. Any arch which uses math-emu to emulate conversions from integers to same-size floats may be affected. The fix is simple: the exponent comparison used to determine if the fraction should be downshifted must be "<=" not "<". I'm sending a kernel module to test this as a reply to this message. There are also SPARC user-space test cases in the GCC bug entry. Signed-off-by: Mikael Pettersson <mikpe@it.uu.se> Signed-off-by: David S. Miller <davem@davemloft.net>
