The memory into which we copy 'u1@u2' needs space for u1, @, u2, and a final \0 which strcat copies in. 2. Strsep changes the value of its first argument. So use a temporary variable to pass to it, so we pass the original value to kfree! 3. Allocate an extra char to user_buf, because we need a trailing \0 since we later kstrdup it. I am about to send out an LTP testcase for this driver, but in addition the correctness of the hashing can be verified as follows: #include <stdio.h> #include <stdlib.h> #include <unistd.h> int main(int argc, char *argv[]) { char in[41], out[20]; unsigned int v; int i, ret; ret = read(STDIN_FILENO, in, 40); if (ret != 40) exit(1); in[40] = '\0'; for (i = 0; i < 20; i++) { sscanf(&in[2*i], "%02x", &v); out[i] = v; } write(STDOUT_FILENO, out, 20); } as root, to test userid 501 switching to uid 0, choosing 'random' string 'ab': echo -n "501@0" > plain openssl sha1 -hmac 'ab' plain |awk '{ print $2 '} > dgst ./unhex < dgst > dgst.u mknod /dev/caphash 504 0 mknod /dev/capuse 504 1 chmod ugo+w /dev/capuse cat dgst.u > /dev/caphash as uid 501, echo "501@0@ab" > /dev/capuse id -u # should now show 0.

| * libata: fix incorrect link online check during probeTejun Heo2009-10-061-18/+32
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | While trying to work around spurious detection retries for non-existent devices on slave links, commit 816ab89782ac139a8b65147cca990822bb7e8675 incorrectly added link offline check logic before ata_eh_thaw() was called. This means that if an occupied link goes down briefly at the time that offline check was performed, device class will be cleared to ATA_DEV_NONE and libata wouldn't retry thus failing detection of the device. The offline check should be done after the port is thawed together with online check so that such link glitches can be detected by the interrupt handler and handled properly.

| * ahci: filter FPDMA non-zero offset enable for Aspire 3810TTejun Heo2009-10-061-0/+47
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Curiously, Aspire 3810T issues many SATA feature enable commands via _GTF, of which one is invalid and another is not supported by the drive. In the process, it also enables FPDMA non-zero offset. However, the feature also needs to be supported and enabled from the controller and it's wrong to enable it from _GTF unless the controller can do it by default. Currently, this ends up enabling FPDMA non-zero offset only on the drive side leading to NCQ command failures and eventual disabling of NCQ. This patch makes libata filter out FPDMA non-zero offset enable for the machine.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Update the AHCI driver to display all of the HBA capabilities defined in the AHCI 1.3 specification. Some of these are in a new CAP2 (HBA Capabilities Extended) register which is only defined on AHCI 1.2 or later. The spec says that undefined registers should always return 0 on read, but to be safe we assume a value of 0 unless the controller reports AHCI version 1.2 or later. The value can also be retrieved through sysfs as with the existing capability field. For example, on an Intel Ibex Peak (PCH) controller: ahci 0000:00:1f.2: flags: 64bit ncq sntf stag pm led clo pmp pio slum part ems sxs apst We don't do anything special with the new flags yet.

While looking at the interaction of decode_mce() with the other MCE code i also noticed a few other things and made the following cleanups/fixes: - Fixed the mce_decode() weak alias - a weak alias is really not good here, it should be a proper callback. A weak alias will be overriden if a piece of code is built into the kernel - not good, obviously. - The patch initializes the callback on AMD family 10h and 11h. - Added the more correct fallback printk of: No support for human readable MCE decoding on this CPU type. Transcribe the message and run it through 'mcelog --ascii' to decode. On CPUs that dont have a decoder. - Made the surrounding code more readable. Note that the callback allows us to have a default fallback - without having to check the CPU versions during the printout itself. When an EDAC module registers itself, it can install the decode-print function. (there's no unregister needed as this is core code.) version -v2 by Borislav Petkov: - add K8 to the set of supported CPUs - always build in edac_mce_amd since we use an early_initcall now - fix checkpatch warnings Signed-off-by: Borislav Petkov <borislav.petkov@amd.com> Cc: Linus Torvalds <torvalds@linux-foundation.org> Cc: Andi Kleen <andi@firstfloor.org> LKML-Reference: <20091001141432.GA11410@aftab> Signed-off-by: Ingo Molnar <mingo@elte.hu>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds support for the setcmap api and fixes the 8bpp support at least on radeon hardware. It adds a new load_lut hook which can be called once the color map is setup. Signed-off-by: Dave Airlie <airlied@redhat.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We can get the corresponding info by adding the boot option of "drm.debug= 0x07". But On some boxes it will print the following message many times in course of moving mouse. In such case the useful DRM debug info will be flushed. >[drm:drm_mode_cursor_ioctl], Avoid using the DRM_DEBUG_KMS in drm_mode_cursor_ioctl.

| | * | | drm/radeon/kms: add support for "Surround View"Alex Deucher2009-10-051-2/+47
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | "Surround View" is an option in the system bios that enables the AMD IGP chip in conjunction with a discrete AMD card. However, since the IGP vbios is part of the system bios it is not accessible via the rom bar or the legacy vga location. When "Surround View" is enabled in the system bios, the system bios puts a copy of the IGP vbios image at the start of vram. This patch adds support for reading the vbios image out of vram on IGP cards. Signed-off-by: Alex Deucher <alexdeucher@gmail.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
