Replace HTTP links with HTTPS ones: DMI/SMBIOS SUPPORT

2020-07-16T09:46:24Z

Rationale: Reduces attack surface on kernel devs opening the links for MITM as HTTPS traffic is much harder to manipulate. Deterministic algorithm: For each file: If not .svg: For each line: If doesn't contain `\bxmlns\b`: For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`: If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`: If both the HTTP and HTTPS versions return 200 OK and serve the same content: Replace HTTP with HTTPS.

firmware/dmi: Report DMI Bios & EC firmware release

2020-06-06T09:35:50Z

Some vendors like HPe or Dell, encode the release version of their BIOS in the "System BIOS {Major|Minor} Release" fields of Type 0. This information is used to know which bios release actually runs. It could be used for some quirks, debugging sessions or inventory tasks. A typical output for a Dell system running the 65.27 bios is : [root@t1700 ~]# cat /sys/devices/virtual/dmi/id/bios_release 65.27 [root@t1700 ~]# Servers that have a BMC encode the release version of their firmware in the "Embedded Controller Firmware {Major|Minor} Release" fields of Type 0. This information is used to know which BMC release actually runs. It could be used for some quirks, debugging sessions or inventory tasks. A typical output for a Dell system running the 3.75 bmc release is : [root@t1700 ~]# cat /sys/devices/virtual/dmi/id/ec_firmware_release 3.75 [root@t1700 ~]# Signed-off-by: Erwan Velu Signed-off-by: Jean Delvare

firmware: dmi: Add macro SMBIOS_ENTRY_POINT_SCAN_START

2020-03-23T14:44:04Z

Use SMBIOS_ENTRY_POINT_SCAN_START instead of 0xF0000, because other archtecture maybe use a special start address such as 0xFFFE000 for Loongson platform. Signed-off-by: Tiezhu Yang Reviewed-by: Jean Delvare Signed-off-by: Thomas Bogendoerfer

firmware: dmi: Add dmi_memdev_handle

2019-12-03T10:20:37Z

Add a utility function dmi_memdev_handle() which returns the DMI handle associated with a given memory slot. This will allow kernel drivers to iterate over the memory slots. Signed-off-by: Jean Delvare

firmware: dmi: Remember the memory type

2019-12-03T10:20:37Z

Store the memory type while walking the memory slots, and provide a way to retrieve it later. Signed-off-by: Jean Delvare

firmware: dmi: Fix unlikely out-of-bounds read in save_mem_devices

2019-10-14T19:41:24Z

Before reading the Extended Size field, we should ensure it fits in the DMI record. There is already a record length check but it does not cover that field. It would take a seriously corrupted DMI table to hit that bug, so no need to worry, but we should still fix it.

treewide: Add SPDX license identifier for missed files

2019-05-21T08:50:45Z

Add SPDX license identifiers to all files which: - Have no license information of any form - Have EXPORT_.*_SYMBOL_GPL inside which was used in the initial scan/conversion to ignore the file These files fall under the project license, GPL v2 only. The resulting SPDX license identifier is: GPL-2.0-only Signed-off-by: Thomas Gleixner Signed-off-by: Greg Kroah-Hartman

efi: Unify DMI setup code over the arm/arm64, ia64 and x86 architectures

2019-03-29T06:35:00Z

All architectures (arm/arm64, ia64 and x86) do the same here, so unify the code. Note: We do not need to call dump_stack_set_arch_desc() in case of !dmi_available. Both strings, dmi_ids_string and dump_stack_arch_ desc_str are initialized zero and thus nothing would change.
