* Documentation/module-signing.txt: Note need for version info if reusing a keyBen Hutchings2016-08-201-0/+6
| | | | | | | | | | | | | | commit b8612e517c3c9809e1200b72c474dbfd969e5a83 upstream. Signing a module should only make it trusted by the specific kernel it was built for, not anything else. If a module signing key is used for multiple ABI-incompatible kernels, the modules need to include enough version information to distinguish them.

* scsi: fix race between simultaneous decrements of ->host_failedWei Fang2016-07-271-2/+6
| | | | | | | | | | | | | | | | | | | | | | | | | commit 72d8c36ec364c82bf1bf0c64dfa1041cfaf139f7 upstream. sas_ata_strategy_handler() adds the works of the ata error handler to system_unbound_wq. This workqueue asynchronously runs work items, so the ata error handler will be performed concurrently on different CPUs. In this case, ->host_failed will be decreased simultaneously in scsi_eh_finish_cmd() on different CPUs, and become abnormal. It will lead to permanently inequality between ->host_failed and ->host_busy, and scsi error handler thread won't start running. IO errors after that won't be handled. Since all scmds must have been handled in the strategy handler, just remove the decrement in scsi_eh_finish_cmd() and zero ->host_busy after the strategy handler to fix this race.

* pipe: limit the per-user amount of pages allocated in pipesWilly Tarreau2016-06-071-0/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit 759c01142a5d0f364a462346168a56de28a80f52 upstream. On no-so-small systems, it is possible for a single process to cause an OOM condition by filling large pipes with data that are never read. A typical process filling 4000 pipes with 1 MB of data will use 4 GB of memory. On small systems it may be tricky to set the pipe max size to prevent this from happening. This patch makes it possible to enforce a per-user soft limit above which new pipes will be limited to a single page, effectively limiting them to 4 kB each, as well as a hard limit above which no new pipes may be created for this user. This has the effect of protecting the system against memory abuse without hurting other users, and still allowing pipes to work correctly though with less data at once. The limit are controlled by two new sysctls : pipe-user-pages-soft, and pipe-user-pages-hard. Both may be disabled by setting them to zero. The default soft limit allows the default number of FDs per process (1024) to create pipes of the default size (64kB), thus reaching a limit of 64MB before starting to create only smaller pipes. With 256 processes limited to 1024 FDs each, this results in 1024*64kB + (256*1024 - 1024) * 4kB = 1084 MB of memory allocated for a user. The hard limit is disabled by default to avoid breaking existing applications that make intensive use of pipes (eg: for splicing).

* Fix OpenSSH pty regression on closeBrian Bloniarz2016-06-011-3/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit 0f40fbbcc34e093255a2b2d70b6b0fb48c3f39aa upstream. OpenSSH expects the (non-blocking) read() of pty master to return EAGAIN only if it has received all of the slave-side output after it has received SIGCHLD. This used to work on pre-3.12 kernels. This fix effectively forces non-blocking read() and poll() to block for parallel i/o to complete for all ttys.

* ata: ahci-platform: Add ports-implemented DT bindings.Srinivas Kandagatla2016-05-111-0/+4
| | | | | | | | | | | | | | | | | | | | | | | commit 17dcc37e3e847bc0e67a5b1ec52471fcc6c18682 upstream. On some SOCs PORTS_IMPL register value is never programmed by the firmware and left at zero value. Which means that no sata ports are available for software. AHCI driver used to cope up with this by fabricating the port_map if the PORTS_IMPL register is read zero, but recent patch broke this workaround as zero value was valid for NVMe disks. This patch adds ports-implemented DT bindings as workaround for this issue in a way that DT can can override the PORTS_IMPL register in cases where the firmware did not program it already.

* KVM: MMU: fix ept=0/pte.u=1/pte.w=0/CR0.WP=0/CR4.SMEP=1/EFER.NX=0 comboPaolo Bonzini2016-03-161-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit 844a5fe219cf472060315971e15cbf97674a3324 upstream. Yes, all of these are needed. :) This is admittedly a bit odd, but kvm-unit-tests access.flat tests this if you run it with "-cpu host" and of course ept=0. KVM runs the guest with CR0.WP=1, so it must handle supervisor writes specially when pte.u=1/pte.w=0/CR0.WP=0. Such writes cause a fault when U=1 and W=0 in the SPTE, but they must succeed because CR0.WP=0. When KVM gets the fault, it sets U=0 and W=1 in the shadow PTE and restarts execution. This will still cause a user write to fault, while supervisor writes will succeed. User reads will fault spuriously now, and KVM will then flip U and W again in the SPTE (U=1, W=0). User reads will be enabled and supervisor writes disabled, going back to the originary situation where supervisor writes fault spuriously. When SMEP is in effect, however, U=0 will enable kernel execution of this page. To avoid this, KVM also sets NX=1 in the shadow PTE together with U=0. If the guest has not enabled NX, the result is a continuous stream of page faults due to the NX bit being reserved. The fix is to force EFER.NX=1 even if the CPU is taking care of the EFER switch. (All machines with SMEP have the CPU_LOAD_IA32_EFER vm-entry control, so they do not use user-return notifiers for EFER---if they did, EFER.NX would be forced to the same value as the host). There is another bug in the reserved bit check, which I've split to a separate patch for easier application to stable kernels.

"rm -rf" is bricking some peoples' laptops because of variables being used to store non-reinitializable firmware driver data that's required to POST the hardware. These are 100% bugs, and they need to be fixed, but in the mean time it shouldn't be easy to *accidentally* brick machines. We have to have delete working, and picking which variables do and don't work for deletion is quite intractable, so instead make everything immutable by default (except for a whitelist), and make tools that aren't quite so broad-spectrum unset the immutable flag.

Particularly, there was a proposal to use this node for the AFS parser too. It can pose a (small) problem to try to differentiate the following nodes: // using binding as currently specified partitions { #address-cells = <x>; #size-cells = <y>; partition@0 { ...; }; }; and // proposed future binding partitions { compatible = "arm,arm-flash-structure"; }; It's especially difficult if other uses of this node start having subnodes. So, since the "partitions" node is new in v4.4, let's fixup the binding before release so that it requires a compatible property, so it's much clearer to distinguish. e.g.: // proposed partitions { compatible = "fixed-partitions"; #address-cells = <x>; #size-cells = <y>; partition@0 { ...; }; }; [1] Subject: "mtd: create a partition type device tree binding" http://lkml.kernel.org/g/20151113220039.GA74382@google.com http://lists.infradead.org/pipermail/linux-mtd/2015-November/063355.html http://lists.infradead.org/pipermail/linux-mtd/2015-November/063364.html Cc: Michal Suchanek <hramrach@gmail.com> Signed-off-by: Brian Norris <computersforpeace@gmail.com> Acked-by: Rob Herring <robh@kernel.org>

The workaround for this issue is to bring up the interface first and then enable SR-IOV as this will trigger the reset in the existing code. I clean up legacy license stuff in the e100.txt documentation and then update the maintainers/reviewers list for our drivers. Jesse fixes an issue with the i40e/i40evf drivers, where if the driver were to happen to have a mutex held while the i40e_init_adminq() call was called, the init_adminq might inadvertently call mutex_init on a lock that was held which is a violation of the calling semantices. ==================== Signed-off-by: David S.

| |/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since Armada 38x SoC can support IP checksum for jumbo frames only on a single port, it means that this feature should be enabled per-port, rather than for the whole SoC. This patch enables setting custom TX IP checksum limit by adding new optional property to the mvneta device tree node. If not used, by default 1600B is set for "marvell,armada-370-neta" and 9800B for other strings, which ensures backward compatibility. Binding documentation is updated accordingly.

This workaround is not needed on other K2 devices such as K2HK and K2E and with this fix, we can remove the workaround altogether. netcp driver on K2L uses linked ram on OSR (On chip Static RAM) and requires the clock to this peripheral enabled for proper functioning. This is the reason for the kernel crash. So add the clock node to fix this issue. While at it, remove the workaround documentation as well. With the fix applied, clk_summary dump shows the clock to OSR enabled. cat /sys/kernel/debug/clk/clk_summary ------cut-------------- tcp3d-1 0 0 399360000 0 0 tcp3d-0 0 0 399360000 0 0 osr 1 1 399360000 0 0 fftc-0 0 0 399360000 0 0 -----cut---------------- Signed-off-by: Murali Karicheri <m-karicheri2@ti.com> Signed-off-by: Santosh Shilimkar <ssantosh@kernel.org>

The 255s timeout was designed to allow kdump and others actions on panic, as in http://lkml.iu.edu/hypermail/linux/kernel/0711.3/0258.html This is counter-intuitive for a end-user who sets watchdog timeout value to something like 30s and who expects BMC to reset the system within 30s of a panic.

Now it only serves as a group of platform APIs such as PM APIs (runtime suspend/resume, system suspend/resume etc), parsers of clocks, regulators and pm_levels from DT. 2. What used to be the old platform "probe" is now "only" a pltfrm_init() routine, that does exactly the same, but only being called by the new probe function of the UFS variant.
