2016-12-06PCI: Add MCFG quirks for Cavium ThunderX pass2.x host controllerTomasz Nowicki5-2/+67
ThunderX PCIe controller to off-chip devices (so-called PEM) is not fully compliant with ECAM standard. It uses non-standard configuration space accessors (see thunder_pem_ecam_ops) and custom configuration space granulation (see bus_shift = 24). In order to access configuration space and probe PEM as ACPI-based PCI host controller we need to add MCFG quirk infrastructure. This involves: 1. A new thunder_pem_acpi_init() init function to locate PEM-specific register ranges using ACPI. 2. Export PEM thunder_pem_ecam_ops structure so it is visible to MCFG quirk code. 3. New quirk entries for each PEM segment. Each contains platform IDs, mentioned thunder_pem_ecam_ops and CFG resources. Quirk is considered for ThunderX silicon pass2.x only which is identified via MCFG revision 1. ThunderX pass 2.x requires the following accessors: NUMA Node 0 PCI segments 0- 3: pci_generic_ecam_ops (ECAM-compliant) NUMA Node 0 PCI segments 4- 9: thunder_pem_ecam_ops (MCFG quirk) NUMA Node 1 PCI segments 10-13: pci_generic_ecam_ops (ECAM-compliant) NUMA Node 1 PCI segments 14-19: thunder_pem_ecam_ops (MCFG quirk) [bhelgaas: adapt to use acpi_get_rc_resources(), update Makefile/ifdefs so quirk doesn't depend on CONFIG_PCI_HOST_THUNDER_PEM] Signed-off-by: Tomasz Nowicki <tn@semihalf.com> Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>

2016-12-06PCI: Add MCFG quirks for HiSilicon Hip05/06/07 host controllersDongdong Liu4-1/+115
The PCIe controller in Hip05/Hip06/Hip07 SoCs is not completely ECAM-compliant. It is non-ECAM only for the RC bus config space; for any other bus underneath the root bus it does support ECAM access. Add specific quirks for PCI config space accessors. This involves: 1. New initialization call hisi_pcie_init() to obtain RC base addresses from PNP0C02 at the root of the ACPI namespace (under \_SB). 2. New entry in common quirk array.

2016-12-06PCI/ACPI: Check for platform-specific MCFG quirksTomasz Nowicki1-6/+86
The PCIe spec (r3.0, sec 7.2.2) specifies an "Enhanced Configuration Access Mechanism" (ECAM) for memory-mapped access to configuration space. ECAM is required for PCIe systems unless there's a standard firmware interface for config access. In the absence of a firmware interface, we use pci_generic_ecam_ops, and on ACPI systems, we discover the ECAM space via the MCFG table and/or the _CBA method. Unfortunately some systems provide MCFG but don't implement ECAM according to spec, so we need a mechanism for quirks to make those systems work. Add an MCFG quirk mechanism to override the config accessor functions and/or the memory-mapped address space. A quirk is selected if it matches all of the following: - OEM ID - OEM Table ID - OEM Revision - PCI segment (from _SEG) - PCI bus number range (from _CRS, wildcard allowed) If the quirk specifies config accessor functions or a memory-mapped address range, these override the defaults.

2016-12-06PCI/ACPI: Extend pci_mcfg_lookup() to return ECAM config accessorsTomasz Nowicki3-16/+33
pci_mcfg_lookup() is the external interface to the generic MCFG code. Previously it merely looked up the ECAM base address for a given domain and bus range. We want a way to add MCFG quirks, some of which may require special config accessors and adjustments to the ECAM address range. Extend pci_mcfg_lookup() so it can return a pointer to a pci_ecam_ops structure and a struct resource for the ECAM address space. For now, it always returns &pci_generic_ecam_ops (the standard accessor) and the resource described by the MCFG. No functional changes intended.

2016-12-06arm64: PCI: Exclude ACPI "consumer" resources from host bridge windowsBjorn Helgaas1-0/+14
On x86 and ia64, we have treated all ACPI _CRS resources of PNP0A03 host bridge devices as "producers", i.e., as host bridge windows. That's partly because some x86 BIOSes improperly used "consumer" descriptors to describe windows and partly because Linux didn't have good support for handling consumer and producer descriptors differently. One result is that x86 BIOSes describe host bridge "consumer" resources in the _CRS of a PNP0C02 device, not the PNP0A03 device itself. On arm64 we don't have a legacy of firmware that has this consumer/producer confusion, so we can handle PNP0A03 "consumer" descriptors as host bridge registers instead of windows. Exclude non-window ("consumer") resources from the list of host bridge windows. This allows the use of "consumer" PNP0A03 descriptors for bridge register space.

2016-12-06arm64: PCI: Manage controller-specific data on per-controller basisTomasz Nowicki1-7/+10
Currently we use one shared global acpi_pci_root_ops structure to keep controller-specific ops. We pass its pointer to acpi_pci_root_create() and associate it with a host bridge instance for good. Such a design implies serious drawback. Any potential manipulation on the single system-wide acpi_pci_root_ops leads to kernel crash. The structure content is not really changing even across multiple host bridges creation; thus it was not an issue so far. In preparation for adding ECAM quirks mechanism (where controller-specific PCI ops may be different for each host bridge) allocate new acpi_pci_root_ops and fill in with data for each bridge. Now it is safe to have different controller-specific info. As a consequence free acpi_pci_root_ops when host bridge is released. No functional changes in this patch.

2016-12-06arm64: PCI: Search ACPI namespace to ensure ECAM space is reservedBjorn Helgaas1-1/+11
The static MCFG table tells us the base of ECAM space, but it does not reserve the space -- the reservation should be done via a device in the ACPI namespace whose _CRS includes the ECAM region. Use acpi_resource_consumer() to check whether the ECAM space is reserved by an ACPI namespace device. If it is, emit a message showing which device reserves it. If not, emit a "[Firmware Bug]" warning. Signed-off-by: Bjorn Helgaas <bhelgaas@google.com> Acked-by: Lorenzo Pieralisi <lorenzo.pieralisi@arm.com>

Add acpi_resource_consumer(). This takes a struct resource and searches the ACPI namespace for a device whose current resource settings (_CRS) includes the resource. It returns the device if it exists, or NULL if no device uses the resource. If more than one device uses the resource (this may happen in the case of bridges), acpi_resource_consumer() returns the first one found by acpi_get_devices() in its modified depth-first walk of the namespace.

2016-10-14fs/super.c: fix race between freeze_super() and thaw_super()Oleg Nesterov1-3/+3
Change thaw_super() to check frozen != SB_FREEZE_COMPLETE rather than frozen == SB_UNFROZEN, otherwise it can race with freeze_super() which drops sb->s_umount after SB_FREEZE_WRITE to preserve the lock ordering. In this case thaw_super() will wrongly call s_op->unfreeze_fs() before it was actually frozen, and call sb_freeze_unlock() which leads to the unbalanced percpu_up_write(). Unfortunately lockdep can't detect this, so this triggers misc BUG_ON()'s in kernel/rcu/sync.c.

2016-10-14iov_iter: kernel-doc import_iovec() and rw_copy_check_uvector()Vegard Nossum2-0/+51
Both import_iovec() and rw_copy_check_uvector() take an array (typically small and on-stack) which is used to hold an iovec array copy from userspace. This is to avoid an expensive memory allocation in the fast path (i.e. few iovec elements). The caller may have to check whether these functions actually used the provided buffer or allocated a new one -- but this differs between the too. Let's just add a kernel doc to clarify what the semantics are for each function. Signed-off-by: Vegard Nossum <vegard.nossum@oracle.com> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
2016-10-14CIFS: Retrieve uid and gid from special sid if enabledSteve French1-0/+123
New mount option "idsfromsid" indicates to cifs.ko that it should try to retrieve the uid and gid owner fields from special sids. This patch adds the code to parse the owner sids in the ACL to see if they match, and if so populate the uid and/or gid from them. This is faster than upcalling for them and asking winbind, and is a fairly common case, and is also helpful when cifs.upcall and idmapping is not configured.
