2014-09-19x86/kaslr: Avoid the setup_data area when picking locationKees Cook1-0/+15
The KASLR location-choosing logic needs to avoid the setup_data list memory areas as well. Without this, it would be possible to have the ASLR position stomp on the memory, ultimately causing the boot to fail.

James Drew reports another bug whereby the NFS client is now sending an OPEN_DOWNGRADE in a situation where it should really have sent a CLOSE: the client is opening the file for O_RDWR, but then trying to do a downgrade to O_RDONLY, which is not allowed by the NFSv4 spec.

2014-09-18NFSv4: nfs4_state_manager() vs. nfs_server_remove_lists()Steve Dickson1-18/+20
There is a race between nfs4_state_manager() and nfs_server_remove_lists() that happens during a nfsv3 mount. The v3 mount notices there is already a supper block so nfs_server_remove_lists() called which uses the nfs_client_lock spin lock to synchronize access to the client list. At the same time nfs4_state_manager() is running through the client list looking for work to do, using the same lock. When nfs4_state_manager() wins the race to the list, a v3 client pointer is found and not ignored properly which causes the panic. Moving some protocol checks before the state checking avoids the panic.

It is wrong that we release the mutex in the failure path in pidlist_array_load(), because cgroup_pidlist_stop() will be called no matter if cgroup_pidlist_start() returns errno or not.

This reverts commit b96de000bc8bc9688b3a2abea4332bd57648a49f. This commit is triggering failures to mount by subvolume id in some configurations.

2014-09-18can: flexcan: put TX mailbox into TX_INACTIVE mode after tx-completeMarc Kleine-Budde1-0/+3
After sending a RTR frame the TX mailbox becomes a RX_EMPTY mailbox. To avoid side effects when the RX-FIFO is full, this patch puts the TX mailbox into TX_INACTIVE mode in the transmission complete interrupt handler. This, of course, leaves a race window between the actual completion of the transmission and the handling of tx-complete interrupt. However this is the best we can do without busy polling the tx complete interrupt. Cc: linux-stable <[email protected]> Signed-off-by: Marc Kleine-Budde <[email protected]>
2014-09-18can: flexcan: implement workaround for errata ERR005829David Jander1-1/+15
This patch implements the workaround mentioned in ERR005829: ERR005829: FlexCAN: FlexCAN does not transmit a message that is enabled to be transmitted in a specific moment during the arbitration process. Workaround: The workaround consists of two extra steps after setting up a message for transmission: Step 8: Reserve the first valid mailbox as an inactive mailbox (CODE=0b1000). If RX FIFO is disabled, this mailbox must be message buffer 0. Otherwise, the first valid mailbox can be found using the "RX FIFO filters" table in the FlexCAN chapter of the chip reference manual. Step 9: Write twice INACTIVE code (0b1000) into the first valid mailbox.

2014-09-18can: flexcan: correctly initialize mailboxesDavid Jander1-0/+7

2014-09-17Revert "init: make rootdelay=N consistent with rootwait behaviour"Paul Gortmaker1-6/+6
This reverts commit 4dfe694f616e00e6fd83e5bbcd7a3c4d7113493d. In that, we did: Here we move the rootdelay code to be right beside the rootwait code, so that their behaviour is consistent. ...which is fine, but in hindsight, perhaps moving the rootwait to be beside the rootdelay would have been better. We also indicated: It should be noted that in doing so, the actions based on the saved_root_name[0] and initrd_load() were previously put on hold by rootdelay=N and now currently will not be delayed. However, I think consistent behaviour is more important than matching historical behaviour of delaying the above two operations. But Pavel reported an instance where an ARM target with root on MMC was failing to mount root, and Russell diagnosed it to the fact that the call to set ROOT_DEV within the saved_root_name[0] processing block mentioned above was no longer being delayed. Rather than moving both wait clauses to the original position of rootdelay and risking unearthing other possible corner case breakage at this point in time, we simply revert now and we can revisit trying the alternate/earlier location in another development cycle.

2014-09-17MIPS: SmartMIPS: Disable assembler warningsMarkos Chandras1-1/+10
The kernel code overrides the default ISA as passed by the compiler in quite a few places. This has unfortunate side effects when smartmips is enabled leading to hundreds of warnings during build such as: {standard input}: Assembler messages: {standard input}:411: Warning: the `smartmips' extension requires MIPS32 revision 1 or greater {standard input}: Assembler messages: {standard input}:43: Warning: the 64-bit MIPS architecture does not support the `smartmips' extension [...] Until the kernel code is fixed properly (if possible), disable all the assembler warning messages to make the build logs readable again. This has no runtime side effects but it makes it easier to spot more critical warnings and problems during build.

power1_input should only be reported for Fam15h, Models 00h-0fh So, introduce a is_visible function to take care of this.

2014-09-16Btrfs: set inode's logged_trans/last_log_commit after ranged fsyncFilipe Manana2-14/+13
When a ranged fsync finishes if there are still extent maps in the modified list, still set the inode's logged_trans and last_log_commit. This is important in case an inode is fsync'ed and unlinked in the same transaction, to ensure its inode ref gets deleted from the log and the respective dentries in its parent are deleted too from the log (if the parent directory was fsync'ed in the same transaction). Instead make btrfs_inode_in_log() return false if the list of modified extent maps isn't empty. This is an incremental on top of the v4 version of the patch: "Btrfs: fix fsync data loss after a ranged fsync" which was added to its v5, but didn't make it on time.

2014-09-16ARM: OMAP3: Fix I/O chain clock line assertion timed out errorTony Lindgren2-5/+36
We are getting "PRM: I/O chain clock line assertion timed out" errors on early omaps for device tree based booting. This is because we are unconditionally calling reconfigure_io_chain while legacy booting has omap3_has_io_chain_ctrl() checks in place in omap_hwmod.c. For device tree based booting, we are calling reconfigure_io_chain unconditionally from pinctrl framework. So we need to add a check for omap3_has_io_chain_ctrl() to avoid the errors for trying to access a register that does not exist. For es3.0, the documentation in "4.11.2 Device Off-Mode Configuration" just mentions PM_WKEN_WKUP[8] bit. For es3.1, there's a new chapter in documentation for "4.11.2.2 I/O Wake-Up Mechanism" that describes the PM_WKEN_WKUP[16] ST_IO_CHAIN bit. So PM_WKEN_WKUP[16] bit did not get added until in es3.1 probaly to fix issues with flakey wake-up events. We are doing proper checks for ST_IO_CHAIN already in id.c and with omap3_has_io_chain_ctrl(). For more information, see also commit b02b917211d5 ("ARM: OMAP3: PM: fix I/O wakeup and I/O chain clock control detection"). Let's fix the issue by selecting the right function during init for reconfigure_io_chain depending on the omap revision. For es3.0 and earlier we need to just toggle EN_IO. By doing this, we can move the check for omap3_has_io_chain_ctrl() from omap_hwmod.c to the init code in prm_3xxx.c. And then we can unconditionally call reconfigure_io_chain. Thanks to Paul Walmsley and Nishanth Menon for help with debugging the issue.
