edd: make kobj_type structure constant

2023-03-09T17:07:33+00:00

Since commit ee6d3dd4ed48 ("driver core: make kobj_type constant.") the driver core allows the usage of const struct kobj_type. Take advantage of this to constify the structure definition to prevent modification at runtime.

firmware: edd: remove empty default_attrs array

2022-01-06T13:28:42+00:00

The default_attrs array of attributes for the edd sysfs entries is totally empty for some reason, and a list of attributes is added later after the object is created (which should be fixed up later as it's racy). Because this pointer is never used, and is empty, and we are trying to remove all default_attrs usages, just delete it.

edd: Use scnprintf() for avoiding potential buffer overflow

2020-04-02T18:42:29+00:00

Since snprintf() returns the would-be-output size instead of the actual output size, the succeeding calls may go beyond the given buffer limit. Fix it by replacing with scnprintf(). Link: https://lore.kernel.org/r/20200320084429.1803-1-tiwai@suse.de Signed-off-by: Takashi Iwai

edd: don't spam log if no EDD information is present

2018-03-27T07:51:23+00:00

We've had reports from users being concerned about messages like: [ 4.487246] BIOS EDD facility v0.16 2004-Jun-25, 0 devices found [ 4.487251] EDD information not available.

edd: Deprecate pci_get_bus_and_slot()

2018-01-11T23:26:28+00:00

pci_get_bus_and_slot() is restrictive such that it assumes domain=0 as where a PCI device is present. This restricts the device drivers to be reused for other domain numbers. Getting ready to remove pci_get_bus_and_slot() function in favor of pci_get_domain_bus_and_slot(). Domain number is not available in struct edd_info. Hard-coding the domain number as 0.

[SCSI] edd: Treat "XPRS" host bus type the same as "PCI"

2011-10-31T09:26:19+00:00

PCI Express devices will return "XPRS" host bus type during BIOS EDD call. "XPRS" should be treated just like "PCI" so that the proper pci_dev symlink will be created. Scripts such as fcoe_edd.sh will then work correctly. Signed-off-by: Michael Chan Reviewed-by: Matt Domsch Signed-off-by: Yi Zou Signed-off-by: James Bottomley

x86, setup: Fix EDD3.0 data verification.

2011-04-27T21:16:12+00:00

Check for nonzero path in edd_has_edd30() has no sense. First, it looks at the wrong memory. Device path starts at offset 30 of the info->params structure which is at offset 8 from the beginning of info structure, but code looks at info + 4 instead. This was correct when code was introduced, but around v2.6.4 three more fields were added to edd_info structure (commit 66b61a5c in history.git). Second, even if it will check correct memory it will always succeed since at offset 30 (params->key) there will be non-zero values otherwise previous check would fail. The patch replaces this bogus check with one that verifies checksum. Signed-off-by: Gleb Natapov Link: http://lkml.kernel.org/r/20110426082132.GG2265@redhat.com Signed-off-by: H. Peter Anvin
