git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs Pull hw lockdown support from David Howells: "Annotation of module parameters that configure hardware resources including ioports, iomem addresses, irq lines and dma channels. This allows a future patch to prohibit the use of such module parameters to prevent that hardware from being abused to gain access to the running kernel image as part of locking the kernel down under UEFI secure boot conditions. Annotations are made by changing: module_param(n, t, p) module_param_named(n, v, t, p) module_param_array(n, t, m, p) to: module_param_hw(n, t, hwtype, p) module_param_hw_named(n, v, t, hwtype, p) module_param_hw_array(n, t, hwtype, m, p) where the module parameter refers to a hardware setting hwtype specifies the type of the resource being configured. This can be one of: ioport Module parameter configures an I/O port iomem Module parameter configures an I/O mem address ioport_or_iomem Module parameter could be either (runtime set) irq Module parameter configures an I/O port dma Module parameter configures a DMA channel dma_addr Module parameter configures a DMA buffer address other Module parameter configures some other value Note that the hwtype is compile checked, but not currently stored (the lockdown code probably won't require it). It is, however, there for future use. A bonus is that the hwtype can also be used for grepping. The intention is for the kernel to ignore or reject attempts to set annotated module parameters if lockdown is enabled. This applies to options passed on the boot command line, passed to insmod/modprobe or direct twiddling in /sys/module/ parameter files. The module initialisation then needs to handle the parameter not being set, by (1) giving an error, (2) probing for a value or (3) using a reasonable default. What I can't do is just reject a module out of hand because it may take a hardware setting in the module parameters. Some important modules, some ipmi stuff for instance, both probe for hardware and allow hardware to be manually specified; if the driver is aborts with any error, you don't get any ipmi hardware. Further, trying to do this entirely in the module initialisation code doesn't protect against sysfs twiddling. [!] Note that in and of itself, this series of patches should have no effect on the the size of the kernel or code execution - that is left to a patch in the next series to effect. It does mark annotated kernel parameters with a KERNEL_PARAM_FL_HWPARAM flag in an already existing field" * tag 'hwparam-20170420' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs: (38 commits) Annotate hardware config module parameters in sound/pci/ Annotate hardware config module parameters in sound/oss/ Annotate hardware config module parameters in sound/isa/ Annotate hardware config module parameters in sound/drivers/ Annotate hardware config module parameters in fs/pstore/ Annotate hardware config module parameters in drivers/watchdog/ Annotate hardware config module parameters in drivers/video/ Annotate hardware config module parameters in drivers/tty/ Annotate hardware config module parameters in drivers/staging/vme/ Annotate hardware config module parameters in drivers/staging/speakup/ Annotate hardware config module parameters in drivers/staging/media/ Annotate hardware config module parameters in drivers/scsi/ Annotate hardware config module parameters in drivers/pcmcia/ Annotate hardware config module parameters in drivers/pci/hotplug/ Annotate hardware config module parameters in drivers/parport/ Annotate hardware config module parameters in drivers/net/wireless/ Annotate hardware config module parameters in drivers/net/wan/ Annotate hardware config module parameters in drivers/net/irda/ Annotate hardware config module parameters in drivers/net/hamradio/ Annotate hardware config module parameters in drivers/net/ethernet/ ...
2017-04-20Annotate hardware config module parameters in drivers/pcmcia/David Howells2-8/+8
When the kernel is running in secure boot mode, we lock down the kernel to prevent userspace from modifying the running kernel image. Whilst this includes prohibiting access to things like /dev/mem, it must also prevent access by means of configuring driver modules in such a way as to cause a device to access or modify the kernel image. To this end, annotate module_param* statements that refer to hardware configuration and indicate for future reference what type of parameter they specify. The parameter parser in the core sees this information and can skip such parameters with an error message if the kernel is locked down. The module initialisation then runs as normal, but just sees whatever the default values for those parameters is. Note that we do still need to do the module initialisation because some drivers have viable defaults set in case parameters aren't specified and some drivers support automatic configuration (e.g. PNP or PCI) in addition to manually coded parameters.

2015-06-16pcmcia: do not break rsrc_nonstatic when handling anonymous cardsDominik Brodowski2-21/+27
Patch 1c6c9b1d9d25 caused a regression for rsrc_nonstatic: It relies on pccard_validate_cis() to determine whether an iomem resource can be used for PCMCIA cards. This override, however, lead invalid iomem resources to be accepted -- and lead to a fake CIS being used instead of the original CIS. To fix this issue, move the override for anonymous cards to the one place where it is needed -- when adding a PCMCIA device. Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>
2015-06-14pcmcia: Fix resource leaks in yenta_probe() and _close()Takeshi Yoshimura1-12/+21
There are some resource leaks in yenta_probe() and _close(). I fixed the following issues with some code cleanups. Thanks to Dominik's suggestions. On the error path in yenta_probe(): - a requested irq is not released - yenta_free_resources() and pci_set_drvdata(dev, NULL) are not called In yenta_close(): - kfree(sock) is not called - sock->base is always set to non-NULL when yenta_close() is called, therefore the check in yenta_close() is not necessary.

2015-06-14Disable write buffering on Toshiba ToPIC95Ryan Underwood1-0/+16
Disable write buffering on the Toshiba ToPIC95 if it is enabled by somebody (it is not supposed to be a power-on default according to the datasheet). On the ToPIC95, practically no 32-bit Cardbus card will work under heavy load without locking up the whole system if this is left enabled. I tried about a dozen. It does not affect 16-bit cards. This is similar to the O2 bugs in early controller revisions it seems. Bugzilla: https://bugzilla.kernel.org/show_bug.cgi?id=55961 Cc: <stable@vger.kernel.org> Signed-off-by: Ryan C.

2015-05-30pcmcia/vrc4171: Remove typedefs for enums and structHimangi Saraogi1-15/+15
The Linux kernel coding style guidelines suggest not using typedefs for structure and enum types. This patch gets rid of the typedefs for vrc4171_slot_t, vrc4171_slotb_t and vrc4171_socket_t. Also, the names of the enums and the struct are changed to drop the _t, to make the name look less typedef-like.
