2023-11-07fmap: Eliminate some impossible code pathsJulius Werner
When the FMAP cache is enabled, it cannot fail in pre-RAM stages unless flash I/O in general doesn't work. Therefore, it is unnecessary and a waste of binary size to also link a fallback path for this case. Similarly, once the cache is written to CAR/SRAM/CBMEM there should be no way for it to become magically corrupted between boot stages. Many other parts of coreboot blindly assume that persistent memory stays valid between stages so there is no reason why this code should link in extra fallback paths in case it doesn't. This saves a little over 200 bytes per affected (uncompressed) stage on aarch64.

2023-11-07fmap: Die immediately on verification failureJulius Werner
A recent security audit has exposed a TOCTOU risk in the FMAP verification code: if the flash returns a tampered FMAP during the first setup_preram_cache(), we will abort generating the cache but only after already filling the persistent CAR/SRAM region with the tampered version. Then we will fall back into the direct access path, which could succeed if the flash now returns the original valid FMAP. In later stages, we will just use the data from the persistent CAR/SRAM region as long as it looks like an FMAP without verifying the hash again (because the hash is only linked into the initial stage). This patch fixes the issue by just calling die() immediately if FMAP hash verification fails. When the verification fails, there's no recourse anyway -- if we're not dying here we would be dying in cbfs_get_boot_device() instead. There is no legitimate scenario where it would still be possible to continue booting after this hash verification fails.

2023-11-07fmap: Map full FMAP for verification in fallback pathJulius Werner
The rarely-used fallback path for accessing the FMAP without a cache currently only maps the FMAP header for the initial verify_fmap() call. This used to be fine when we were just checking the magic number, but with CBFS verification we may need to hash the entire FMAP. Since this path is so rarely used anyway and the size difference only has a practical impact on a few platforms, lets keep things simple and just always map the whole FMAP.

2023-10-20x86: Add ramstage CBFS cache scratchpad supportJeremy Compostella
Having a CBFS cache scratchpad offers a generic way to decompress CBFS files through the cbfs_map() function without having to reserve a per-file specific memory region. This commit introduces the x86 `RAMSTAGE_CBFS_CACHE_SIZE' Kconfig to set a ramstage CBFS cache size. A cache size of zero disables the CBFS cache feature. The default size is 16 KB which seems a reasonable minimal value large enough to satisfy basic needs such as the decompression of a small configuration file. This setting can be adjusted depending on the platform needs and capabilities. To support S3 suspend/resume use-case, the CBFS cache memory cannot be released to the operating system. There are two options to meet this requirement: 1. Define a static CBFS cache buffer (located in the .bss section) 2. Create a new CBMEM entry Option #2 seems more powerful but considering that: 1. The CBFS cache is actually not a cache but just a scratch pad designed to be isolated between stages 2. postcar is a very short stage not really needing CBFS cache 3. The static initialization of the `cbfs_cache' global variable (cf. src/lib/cbfs.c) offers a simple and robust design => It is simpler to use a static buffer and limit the support to ramstage. Since some AMD SoCs (cf. `SOC_AMD_COMMON_BLOCK_NONCAR' Kconfig) define a `_cbfs_cache' region, an extra `POSTRAM_CBFS_CACHE_IN_BSS' Kconfig must be set to enable the use of a static buffer as the CBFS cache scratchpad.

2023-09-14x86: Add .data section support for pre-memory stagesJeremy Compostella
x86 pre-memory stages do not support the `.data` section and as a result developers are required to include runtime initialization code instead of relying on C global variable definition. To illustrate the impact of this lack of `.data` section support, here are two limitations I personally ran into: 1. The inclusion of libgfxinit in romstage for Raptor Lake has required some changes in libgfxinit to ensure data is initialized at runtime. In addition, we had to manually map some `.data` symbols in the `_bss` region. 2. CBFS cache is currently not supported in pre-memory stages and enabling it would require to add an initialization function and find a generic spot to call it. Other platforms do not have that limitation. Hence, resolving it would help to align code and reduce compilation based restriction (cf. the use of `ENV_HAS_DATA_SECTION` compilation flag in various places of coreboot code). We identified three cases to consider: 1. eXecute-In-Place pre-memory stages - code is in SPINOR - data is also stored in SPINOR but must be linked in Cache-As-RAM and copied there at runtime 2. `bootblock` stage is a bit different as it uses Cache-As-Ram but the memory mapping and its entry code different 3. pre-memory stages loaded in and executed from Cache-As-RAM (cf. `CONFIG_NO_XIP_EARLY_STAGES`). eXecute-In-Place pre-memory stages (#1) require the creation of a new ELF segment as the code segment Virtual Memory Address and Load Memory Address are identical but the data needs to be linked in cache-As-RAM (VMA) but to be stored right after the code (LMA). Here is the output `readelf --segments` on a `romstage.debug` ELF binary. Program Headers: Type Offset VirtAddr PhysAddr FileSiz MemSiz Flg Align LOAD 0x000080 0x02000000 0x02000000 0x21960 0x21960 R E 0x20 LOAD 0x0219e0 0xfefb1640 0x02021960 0x00018 0x00018 RW 0x4 Section to Segment mapping: Segment Sections... 00 .text 01 .data Segment 0 `VirtAddr` and `PhysAddr` are at the same address while they are totally different for the Segment 1 holding the `.data` section. Since we need the data section `VirtAddr` to be in the Cache-As-Ram and its `PhysAddr` right after the `.text` section, the use of a new segment is mandatory. `bootblock` (#2) also uses this new segment to store the data right after the code and load it to Cache-As-RAM at runtime. However, the code involved is different. Not eXecute-In-Place pre-memory stages (#3) do not really need any special work other than enabling a data section as the code and data VMA / LMA translation vector is the same. TEST=#1 and #2 verified on rex and qemu 32 and 64 bits: - The `bootblock.debug`, `romstage.debug` and `verstage.debug` all have data stored at the end of the `.text` section and code to copy the data content to the Cache-As-RAM. - The CBFS stages included in the final image has not improperly relocated any of the `.data` section symbol. - Test purposes global data symbols we added in bootblock, romstage and verstage are properly accessible at runtime #3: for "Intel Apollolake DDR3 RVP1" board, we verified that the generated romstage ELF includes a .data section similarly to a regular memory enabled stage.

We only checked that the resource fits below the given `limit` in memranges_find_entry(), but then accidentally placed it at the top of the found memrange. As most resources have only a coarse limit, e.g. the 4G barrier of 32-bit space, this became only visible when artificially setting an unusual, lower limit on a resource. So, for the final placement, use `MIN(limit, range end)` instead of the range's end alone.

2023-05-16lib: Perform display init in normal boot mode if BMP_LOGO is setSubrata Banik
Traditionally, display init during vboot "verified/secure/normal boot mode" relies on the VB2_CONTEXT_DISPLAY_INIT. This is the default behavior for vboot, meaning skip display init during verified boot mode. However, if the intention is to show the OEM splash screen (using BMP_LOGO config) during boot, then the policy enforced by vboot needs to be overridden. This can be done by setting the BMP_LOGO config flag. If BMP_LOGO is not enabled, then the vboot policy will be followed and display init will be skipped. This change was made to allow OEMs to show their splash screen during boot, even if the system is in verified/secure/normal mode.

2023-03-03lib: set up specific purpose memory as LB_MEM_SOFT_RESERVEDJonathan Zhang
CXL (Compute Express Link) [1] is a cache-coherent interconnect standard for processors, memory expansion and accelerators. CXL memory is provided through CXL device which is connected through CXL/PCIe link, while regular system memory is provided through DIMMs plugged into DIMM slots which are connected to memory controllers of processor. With CXL memory, the server's memory capacity is increased. CXL memory is in its own NUMA domain, with longer latency and added bandwidth, comparing to regular system memory. Host firmware may present CXL memory as specific purpose memory. Linux kernel dax driver provides direct access to such differentiated memory. In particular, hmem dax driver provides direct access to specific purpose memory. Specific purpose memory needs to be represented in e820 table as soft reserved, as described in [2]. Add IORESOURCE_SOFT_RESERVE resource property to indicate (memory) resource that needs to be soft reserved. Add soft_reserved_ram_resource macro to allow soc/mb code to add memory resource as soft reserved.

While the existing implementation has been producing tables with a well-defined alignment (4 bytes) for a long time, the code doesn't always make it very clear.

2022-12-17lib: Hook up libhwbase in romstageJeremy Compostella
It's hidden behind the configuration option `CONFIG_ROMSTAGE_LIBHWBASE'. This also adds some glue code to use the coreboot console for debug output and our monotonic timer framework as timer backend. Running Ada code in romstage and more particular libhwbase brings a few challenges as global initialized variables are not supported in Cache-As-Ram mode. 1. The libhwbase dynamic mmio driver implementation makes the Gnat compiler generate some global initialized variables. For this reason, when compiled for romstage or for romstage and ramstage the static mmio driver is enforced (`HWBASE_STATIC_MMIO'). 2. The Gnat compiler generates elaboration functions to initialize program data at runtime. These elaboration functions are called by the romstage_adainit() function. The data references symbols suffixed by `_E'. Even though these symbols, at compilation time, do not contain any data and are filled with zeros, the Gnat compiler installs them in the .data section. Since these symbols are actually filled with zeros, it is safe to install them in the .bss section. cf. https://docs.adacore.com/gnat_ugn-docs/html/gnat_ugn/gnat_ugn/elaboration_order_handling_in_gnat.html#elaboration-code This patch requires the libhwbase https://review.coreboot.org/c/libhwbase/+/69854 CL.

CL:3825558 changes all vb2_digest and vb2_hash functions to take a new hwcrypto_allowed argument, to potentially let them try to call the vb2ex_hwcrypto API for hash calculation. This change will open hardware crypto acceleration up to all hash calculations in coreboot (most notably CBFS verification).

Implementation of free() does something only for one last malloc'ed block, making most of freed memory unavailable for future allocation.

2022-03-09cpu/x86/smm,lib/cbmem_console: Enable CBMEMC when using DEBUG_SMIRaul E Rangel
This change will allow the SMI handler to write to the cbmem console buffer. Normally SMIs can only be debugged using some kind of serial port (UART). By storing the SMI logs into cbmem we can debug SMIs using `cbmem -1`. Now that these logs are available to the OS we could also verify there were no errors in the SMI handler. Since SMM can write to all of DRAM, we can't trust any pointers provided by cbmem after the OS has booted. For this reason we store the cbmem console pointer as part of the SMM runtime parameters. The cbmem console is implemented as a circular buffer so it will never write outside of this area. BUG=b:221231786 TEST=Boot non-serial FW with DEBUG_SMI and verified SMI messages are visible when running `cbmem -1`. Perform a suspend/resume cycle and verify new SMI events are written to the cbmem console log.

2022-03-09commonlib/bsd: Remove cb_err_tJulius Werner
cb_err_t was meant to be used in place of `enum cb_err` in all situations, but the choice to use a typedef here seems to be controversial. We should not be arbitrarily using two different identifiers for the same thing across the codebase, so since there are no use cases for serializing enum cb_err at the moment (which would be the primary reason to typedef a fixed-width integer instead), remove cb_err_t again for now.

This patch aims to make timestamps more consistent in naming, to follow one pattern. Until now there were many naming patterns: - TS_START_*/TS_END_* - TS_BEFORE_*/TS_AFTER_* - TS_*_START/TS_*_END This change also aims to indicate, that these timestamps can be used to create time-ranges, e.g. from TS_BOOTBLOCK_START to TS_BOOTBLOCK_END.

Now that the console system itself will clearly differentiate loglevels, it is no longer necessary to explicitly add "ERROR: " in front of every BIOS_ERR message to help it stand out more (and allow automated tooling to grep for it). Removing all these extra .rodata characters should save us a nice little amount of binary size. This patch was created by running find src/ -type f -exec perl -0777 -pi -e 's/printk\(\s*BIOS_ERR,\s*"ERROR: /printk\(BIOS_ERR, "/gi' '{}' ';' and doing some cursory review/cleanup on the result.

2022-02-07console: Add loglevel marker codes to stored consolesJulius Werner
In order to provide the same loglevel prefixes and highlighting that were recently introduced for "interactive" consoles (e.g. UART) to "stored" consoles (e.g. CBMEM) but minimize the amont of extra storage space wasted on this info, this patch will write a 1-byte control character marker indicating the loglevel to the start of every line logged in those consoles. The `cbmem` utility will then interpret those markers and translate them back into loglevel prefixes and escape sequences as needed. Since coreboot and userspace log readers aren't always in sync, occasionally an older reader may come across these markers and not know how to interpret them... but that should usually be fine, as the range chosen contains non-printable ASCII characters that normally have no effect on the terminal. At worst the outdated reader would display one garbled character at the start of every line which isn't that bad. (Older versions of the `cbmem` utility will translate non-printable characters into `?` question marks.)
