2016-05-11irqchip/gic-v3: Remove inexistant register definitionMarc Zyngier
The GICv3 include file defines GICR_ISACTIVER and GICR_ICACTIVER in the RD_base page. News flash, they do not exist (probably a copy/paste brain fart). Just drop them. Signed-off-by: Marc Zyngier <marc.zyngier@arm.com>
2016-05-11irqchip/gicv3-its: Don't allow devices whose ID is outside rangeShanker Donthineni
We are not checking whether the requested device identifier fits into the device table memory or not. The function its_create_device() assumes that enough memory has been allocated for whole DevID space (reported by ITS_TYPER.Devbits) during the ITS probe() and continues to initialize ITS hardware. This assumption is not perfect, sometimes we reduce memory size either because of its size crossing MAX_ORDER-1 or BASERn max size limit. The MAPD command fails if 'Device ID' is outside of device table range. Add a simple validation check to avoid MAPD failures since we are not handling ITS command errors. This change also helps to return an error -ENOMEM instead of success to caller. Signed-off-by: Shanker Donthineni <shankerd@codeaurora.org> Signed-off-by: Marc Zyngier <marc.zyngier@arm.com>
2016-05-11irqchip: Add LPC32xx interrupt controller driverVladimir Zapolskiy
The change adds improved support of NXP LPC32xx MIC, SIC1 and SIC2 interrupt controllers. This is a list of new features in comparison to the legacy driver: * irq types are taken from device tree settings, no more need to hardcode them, * old driver is based on irq_domain_add_legacy, which causes problems with handling MIC hardware interrupt 0 produced by SIC1, * there is one driver for MIC, SIC1 and SIC2, no more need to handle them separately, e.g. have two separate handlers for SIC1 and SIC2, * the driver does not have any dependencies on hardcoded register offsets, * the driver is much simpler for maintenance, * SPARSE_IRQS option is supported. Legacy LPC32xx interrupt controller driver was broken since commit 76ba59f8366f ("genirq: Add irq_domain-aware core IRQ handler"), which requires a private interrupt handler, otherwise any SIC1 generated interrupt (mapped to MIC hwirq 0) breaks the kernel with the message "unexpected IRQ trap at vector 00". The change disables compilation of a legacy driver found at arch/arm/mach-lpc32xx/irq.c, the file will be removed in a separate commit.

2016-05-11irqchip/gic: Ensure ordering between read of INTACK and shared dataWill Deacon
When an IPI is generated by a CPU, the pattern looks roughly like: <write shared data> smp_wmb(); <write to GIC to signal SGI> On the receiving CPU we rely on the fact that, once we've taken the interrupt, then the freshly written shared data must be visible to us. Put another way, the CPU isn't going to speculate taking an interrupt. Unfortunately, this assumption turns out to be broken. Consider that CPUx wants to send an IPI to CPUy, which will cause CPUy to read some shared_data. Before CPUx has done anything, a random peripheral raises an IRQ to the GIC and the IRQ line on CPUy is raised. CPUy then takes the IRQ and starts executing the entry code, heading towards gic_handle_irq. Furthermore, let's assume that a bunch of the previous interrupts handled by CPUy were SGIs, so the branch predictor kicks in and speculates that irqnr will be <16 and we're likely to head into handle_IPI. The prefetcher then grabs a speculative copy of shared_data which contains a stale value. Meanwhile, CPUx gets round to updating shared_data and asking the GIC to send an SGI to CPUy. Internally, the GIC decides that the SGI is more important than the peripheral interrupt (which hasn't yet been ACKed) but doesn't need to do anything to CPUy, because the IRQ line is already raised. CPUy then reads the ACK register on the GIC, sees the SGI value which confirms the branch prediction and we end up with a stale shared_data value. This patch fixes the problem by adding an smp_rmb() to the IPI entry code in gic_handle_irq. As it turns out, the combination of a control dependency and an ISB instruction from the EOI in the GICv3 driver is enough to provide the ordering we need, so we add a comment there justifying the absence of an explicit smp_rmb().

The identity mapping is suboptimal for the last 2GB frame. The mapping will be established with a mix of 4KB and 1MB mappings instead of a single 2GB mapping. This happens because of a off-by-one bug introduced with commit 50be63450728 ("s390/mm: Convert bootmem to memblock").

2016-05-10ovl: ignore permissions on underlying lookupMiklos Szeredi
Generally permission checking is not necessary when overlayfs looks up a dentry on one of the underlying layers, since search permission on base directory was already checked in ovl_permission(). More specifically using lookup_one_len() causes a problem when the lower directory lacks search permission for a specific user while the upper directory does have search permission. Since lookups are cached, this causes inconsistency in behavior: success depends on who did the first lookup. So instead use lookup_hash() which doesn't do the permission check.

2016-05-10vfs: add lookup_hash() helperMiklos Szeredi
Overlayfs needs lookup without inode_permission() and already has the name hash (in form of dentry->d_name on overlayfs dentry). It also doesn't support filesystems with d_op->d_hash() so basically it only needs the actual hashed lookup from lookup_one_len_unlocked() So add a new helper that does unlocked lookup of a hashed name.

2016-05-10vfs: rename: check backing inode being equalMiklos Szeredi
If a file is renamed to a hardlink of itself POSIX specifies that rename(2) should do nothing and return success. This condition is checked in vfs_rename(). However it won't detect hard links on overlayfs where these are given separate inodes on the overlayfs layer. Overlayfs itself detects this condition and returns success without doing anything, but then vfs_rename() will proceed as if this was a successful rename (detach_mounts(), d_move()). The correct thing to do is to detect this condition before even calling into overlayfs. This patch does this by calling vfs_select_inode() to get the underlying inodes.

2016-05-10Merge branch 'phy_ksettings'David S. Miller
Philippe Reynes says: ==================== net: phy: add phy_ethtool_{get|set}_link_ksettings Ethtool callbacks {get|set}_link_ksettings may be the same for many drivers. So we add two generics callbacks phy_ethtool_{get|set}_link_ksettings. To use those generics callbacks, the ethernet driver must use the pointer phydev contained in struct net_device, and not use a private structure to store this pointer. Changelog: v3: - rename function to phy_ethtool_{get|set}_link_ksettings - move code to net/phy/phy.c This feedback were provided by David Decotigny v2: - use generic function instead of macro - ethernet driver use the pointer phydev provided by struct net_device Those idea were provided by Ben Hutchings, and Florian Fainelli acknowledge them. ==================== Signed-off-by: David S.
