* dmidecode: Add helper function pr_subattrJean Delvare2020-04-011-32/+36
| | | | | | Print all second-level attributes through a helper function pr_subattr. Signed-off-by: Jean Delvare <jdelvare@suse.de>
* dmidecode: Add helper functions pr_list_start/item/endJean Delvare2020-04-011-114/+146
| | | | | | | | | Print lists through helper functions. pr_list_start() starts the list, with an optional value. pr_list_item() prints a single item. pr_list_end() is a no-op for plain text output, but is in place in anticipation of supporting other output formats such as HTML.

* dmidecode: Refactor ASCII filtering of DMI stringsJean Delvare2020-03-231-28/+32
| | | | | | | | | | Split dmi_string into 3 functions to make it more modular. ASCII filtering is an explicit option now to give the caller more control. Use the new functions in dmi_dump to avoid reimplementing the ASCII filtering and printing characters one by one. Signed-off-by: Jean Delvare <jdelvare@suse.de>
* dmidecode: Move type 42 warning messages to stderrJean Delvare2020-03-231-4/+6
| | | | | | | | | | Write warning messages about invalid type 42 structures to stderr as we do for all other warning messages. Also include the handle and record numbers in these warning messages to make the problem easier to analyze. Signed-off-by: Jean Delvare <jdelvare@suse.de>
* dmidecode: Reduce the indentation of type 42 structuresJean Delvare2020-03-231-20/+20
| | | | | | | | There is no reason to indent the device information that much in type 42 structures. Remove the extra level of indentation for consistency and readability. Signed-off-by: Jean Delvare <jdelvare@suse.de>

* dmidecode: Simplify the formatting of memory error statusJean Delvare2020-03-231-9/+10
| | | | | | | Make the logic more simple so that we always report the status on a single line. Signed-off-by: Jean Delvare <jdelvare@suse.de>
* dmidecode: Don't choke on invalid processor voltageJean Delvare2020-03-231-2/+2
| | | | | | | | If the processor voltage encoding has some of the reserved bits set and none of the proper bits set, print it as "Unknown" instead of an empty field. Signed-off-by: Jean Delvare <jdelvare@suse.de>
* dmidecode: Print type 33 name unconditionallyJean Delvare2020-03-231-1/+1
| | | | | | | Even if a type 33 structure is too short, we can still display its type name as we do for all other structure types. Signed-off-by: Jean Delvare <jdelvare@suse.de>
* dmidecode: Decode system slot base bus width and peersJean Delvare2019-10-231-0/+15
| | | | | | | | SMBIOS version 3.2.0 added extra fields are the end of structure type 9. Decode these extra fields (base data bus width and peers) when present. Signed-off-by: Jean Delvare <jdelvare@suse.de>

* dmidecode: Adding firmware-revision support to -s optionErwan Velu2019-10-071-0/+4
| | | | | | | | | | | | | | Most of servers like HPe, QCT, report the BMC version via the Firmware Revision field. Add an option to the -s to export this information directly. A typical usage of this feature looks like: [root@host ~]$ dmidecode -s firmware-revision 3.93 Signed-off-by: Erwan Velu <e.velu@criteo.com> Signed-off-by: Jean Delvare <jdelvare@suse.de>
* dmidecode: Adding bios-revision to -s optionErwan Velu2019-10-071-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | Some hardware vendors like HPe use the Version field to store the bios generation like (U30, U32, A40, ...). If you want to get the "release" version of this bios generation, the bios revision field must be considered. A typical output of this kind of server looks like : BIOS Information Vendor: HPE Version: A40 Release Date: 07/20/2019 [...] BIOS Revision: 2.0 Firmware Revision: 1.45 Add a "bios-revision" entry into the '-s' option.

* Fix formatting of TPM table outputDeomid rojer Ryabkov2019-08-261-2/+2
| | | | | | Added missing newlines. Fixes: 48a8132058a0 ("dmidecode: Add support for structure type 43 (TPM Device)")
* Use larger units for memory device and BIOS sizeDeomid rojer Ryabkov2019-08-261-5/+8
| | | | | | | So, 8 MB instead of 8192 kB, 8 GB instead of 8192 MB. Same principle as in c43afb47fcba ("dmidecode: Use the most appropriate unit for cache size") applied to more fields.
* dmidecode: Only scan /dev/mem for entry point on x86Jean Delvare2019-08-261-3/+5
| | | | | | | | | x86 is the only architecture which can have a DMI entry point scanned from /dev/mem. Do not attempt it on other architectures, because not only it can't work, but it can even cause the system to reboot. This fixes support request #109697: https://savannah.nongnu.org/support/?109697

* dmidecode: Add "Logical non-volatile device" to the memory device typesJean Delvare2019-01-161-2/+3
| | | | | | | | | | When adding support for non-volative memory, we forgot to add "Logical non-volatile device" to the list of memory types. This causes NVDIMM modules to show up as <OUT OF SPEC>. Fix the problem by adding the missing enumerated value. Signed-off-by: Jean Delvare <jdelvare@suse.de> Reviewed-by: Jerry Hoemann <jerry.hoemann@hpe.com>
* dmidecode: Use dmi_cache_size_2 in dmi_cache_sizeJean Delvare2019-01-151-8/+5
| | | | | | | | | Redirect dmi_cache_size() to dmi_cache_size_2() so that the cache size is always reported using the most appropriate unit, even if the BIOS does not populate the 32-bit cache size fields. Signed-off-by: Jean Delvare <jdelvare@suse.de> Acked-by: Neil Horman <nhorman@tuxdriver.com>
* dmidecode: Use the most appropriate unit for cache sizeJean Delvare2019-01-151-6/+11
| | | | | | | | | | | As newer CPUs have larger and larger cache, using kB to represent the cache size is getting less convenient. Reuse the same function we have for system memory size so that large units will be used as appropriate. For example, a cache size reported as "20 MB" looks nicer than as "20480 kB".

| | | | | | | | | | | | | Starting with version 3.2.0 the SMBIOS specification defined in more detail the contents of the management controller type.

* dmidecode: Validate structure completeness before decodingJean Delvare2018-08-011-17/+22
| | | | | | | | | | | | | | | Ensure that the whole DMI structure fits in the announced table length before performing any action on it. Otherwise we might end up reading beyond the end of our memory buffer. This bug was discovered by Lionel Debroux using the AFL fuzzer and AddressSanitizer. Its probability is very low, as it requires a DMI table corrupted in one of two very specific ways to trigger. This bug exists since dmidecode version 2.9, although it is hard to test because option --from-dump was only introduced in version 2.10. Signed-off-by: Jean Delvare <jdelvare@suse.de>
* dmidecode: Avoid OOB read on invalid entry point lengthJean Delvare2018-08-011-0/+18

* dmidecode: Share common EFI codeJean Delvare2017-11-301-7/+8

* UEFI support on FreeBSDAlexey Dokuchaev2017-11-301-0/+33
| | | | | | | | | | | | | | | Currently, dmidecode(8) does not work on FreeBSD booted in UEFI mode. Previously it was understandable, since there are no things like Linuxish /proc/efi/systab or /sys/firmware/efi/systab to read from under FreeBSD. However, 7 months ago, ambrisko@ had added support for exposing the SMBIOS anchor base address via kernel environment: https://svnweb.freebsd.org/base?view=revision&revision=307326 I've patched dmidecode.c to try to get the address from hint.smbios.0.mem and fall back to traditional address space scanning. I've tested it both on EFI (amd64 laptop) and non-EFI (i386 desktop) machines.
