* Add i2c_board_info for RiscPC PCF8583Russell King2009-02-242-1/+8

* i2c: Make sure i2c_algo_bit_data.timeout is HZ-independentJean Delvare2009-02-243-3/+3
| | | | | | | | | | | | | i2c_algo_bit_data.timeout is supposed to be in jiffies, so drivers should use set this value in terms of HZ. Ultimately I think this field should be discarded in favor of i2c_adapter.timeout, but that's left for a future patch.

* i2c-dev: Clarify the unit of ioctl I2C_TIMEOUTJean Delvare2009-02-243-3/+7
| | | | | | | | | | | The unit in which user-space can set the bus timeout value is jiffies for historical reasons (back when HZ was always 100.) This is however not good because user-space doesn't know how long a jiffy lasts. The timeout value should instead be set in a fixed time unit. Given the original value of HZ, this unit should be 10 ms, for compatibility. Signed-off-by: Jean Delvare <khali@linux-fr.org> Acked-by: Wolfram Sang <w.sang@pengutronix.de>
* i2c: Timeouts reach -1Roel Kluin2009-02-242-3/+3
| | | | | | | | | | | | With a postfix decrement these timeouts reach -1 rather than 0, but after the loop it is tested whether they have become 0. As pointed out by Jean Delvare, the condition we are waiting for should also be tested before the timeout. With the current order, you could exit with a timeout error while the job is actually done.

| | | | | | | | | | | | | | | | | | | | | | | | | | The fix for CVE-2009-0676 (upstream commit df0bca04) is incomplete. Note that the same problem of leaking kernel memory will reappear if someone on some architecture uses struct timeval with some internal padding (for example tv_sec 64-bit and tv_usec 32-bit) --- then, you are going to leak the padded bytes to userspace.

* | proc: proc_get_inode should de_put when inode already initializedKrzysztof Sachanowicz2009-02-231-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | de_get is called before every proc_get_inode, but corresponding de_put is called only when dropping last reference to an inode. This might cause something like remove_proc_entry: /proc/stats busy, count=14496 to be printed to the syslog. The fix is to call de_put in case of an already initialized inode in proc_get_inode.

| * | netns: fix double free at netns creationDaniel Lezcano2009-02-221-31/+55
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fix a double free when a network namespace fails. The previous code does a kfree of the net_generic structure when one of the init subsystem initialization fails. The 'setup_net' function does kfree(ng) and returns an error. The caller, 'copy_net_ns', call net_free on error, and this one calls kfree(net->gen), making this pointer freed twice. This patch make the code symetric, the net_alloc does the net_generic allocation and the net_free frees the net_generic. Signed-off-by: Daniel Lezcano <daniel.lezcano@free.fr> Signed-off-by: David S.

| * | wimax/i2400m: driver loads firmware v1.4 instead of v1.3Inaky Perez-Gonzalez2009-02-201-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a one liner change to have the driver use by default the v1.4 of the i2400m firmware instead of v1.3. The v1.4 version of the firmware has been submitted to David Woodhouse for inclusion in the linux-firmware tree and it is already available at http://linuxwimax.org/Download. The reason for this change is that the 1.3 release of the user space software and firmware has a few issues that will make it difficult to use with currently deployed commercial networks such as Xohm and Clearwire. As well, the new 1.4 release of the user space software (which matches the 1.4 firmware) has intermitent issues with the 1.3 firmware. The 1.4 release in http://linuxwimax.org/Download has been widely deployed and tested with the codebase in 2.6.29-rc, the 1.4 firmware and the 1.4 user space components. We understand it is quite late in the rc process for such a change, but would like to ask for the change to be taken into consideration. Alternatively, a user could always force feed a 1.4 firmware into a driver that doesn't have this modification by: $ cd /lib/firmware $ mv i2400m-fw-usb-1.3.sbcf i2400m-fw-usb-1.3.real.sbcf $ ln -sf i2400m-fw-usb-1.4.sbc i2400m-fw-usb-1.3.sbcf Signed-off-by: Inaky Perez-Gonzalez <inaky@linux.intel.com> Signed-off-by: David S.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | mib_counters_update() also restarts the timer. So the timer is dequeued, the stats are read and then the timer is enqueued again. This is "okay" unless someone unloads the module. The locking here is also broken: mib_counters_update() grabs just a simple spinlock. The only thing the lock is good for is to protect the timer func against other callers namely mv643xx_eth_stop() && mv643xx_eth_get_ethtool_stats(). That means if the spinlock is taken via the ethtool path and than the timer kicks in then the box will lock up.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This ensures that the user gets the latest information from the hardware on whether the buffer is busy, potentially reducing the working set of objects that the user chooses.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In the KMS case, we need to suspend/resume GEM as well. So on suspend, make sure we idle GEM and stop any new rendering from coming in, and on resume, re-init the framebuffer and clear the suspended flag.

| * | | drm/i915: Don't let a device flush to prepare buffers clear new write_domains.Eric Anholt2009-02-231-2/+14

Instead, hang on to the new (or old if we're not changing it) value and set it after the flush is queued. Results from this noticably included conformance test failures from reads shortly after writes (where the new write domain had been lost and thus not flushed and waited on), but is a suspected cause of hangs in some apps when a write domain is lost on a buffer that gets reused for instruction or commmand state.

The problem was noticed by someone trying to use the "-R" (record route) option of ping: # ping -R 10.0.0.1 ping: record route: No message of desired type The solution is relatively simple, we catch the unlabeled socket case and clear the error code, allowing the operation to succeed. Please note that we still deny users the ability to override IPv4 options on socket's which have NetLabel labeling active; this is done to ensure the labeling remains intact.

|/ / / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The CIPSO protocol engine incorrectly stated that the FIPS-188 specification could be found in the kernel's Documentation directory. This patch corrects that by removing the comment and directing users to the FIPS-188 documented hosted online. For the sake of completeness I've also included a link to the CIPSO draft specification on the NetLabel website. Thanks to Randy Dunlap for spotting the error and letting me know.

This allows these docbooks to be generated in parallel. (This reduced the docbook processing time on my 4-proc system with make -j4 from about 5min:16sec to about 2min:01sec.)
