2024-02-02util/cbmem: Use commonlib ipchksum() algorithmJulius Werner
This patch switches the cbmem utility from its own IP checksum implementation to the commonlib version (which is good because the old one had a couple of bugs: doesn't work on odd sizes and may overflow its carry accumulator with input larger than 64K).

2023-07-04util/cbmem: add parsing of TPM logs per specsSergii Dmytruk
CBMEM can contain log in different forms (at most one is present): - coreboot-specific format (CBMEM_ID_TPM_CB_LOG exported as LB_TAG_TPM_CB_LOG) - TPM1.2 format (CBMEM_ID_TCPA_TCG_LOG) - TPM2 format (CBMEM_ID_TPM2_TCG_LOG) The last two follow specifications by Trusted Computing Group, but until now cbmem couldn't print them. These formats were added not so long ago in: - commit 4191dbf0c9a5 ("security/tpm: add TPM log format as per 1.2 spec") - commit 53db677586e3 ("security/tpm: add TPM log format as per 2.0 spec") These changes make cbmem utility check for existence of TPM1.2/TPM2 logs in CBMEM and add code necessary for parsing and printing of their entries.

2022-03-10cbmem: Fix console banner matchesJulius Werner
Since the new loglevel markers were added, there will now be a marker character at the beginning of the coreboot banner string, and this will make the existing regular expressions meant to find it fail to match. This patch fixes the problem by just allowing for a single extra character there (any character to avoid the hassle of having to match the marker explicitly). The extra character is optional so that we will still continue to match banners from older versions of coreboot as well. Since the `?` glyph is not available in basic POSIX regular expressions, we have to switch to REG_EXTENDED syntax (should otherwise make no difference). (Also, move side effects out of assert() while I'm here, that's not actually safe for the standard libc implementation.)

2022-02-11util/cbmem: Add --loglevel option to restrict console printing by levelJulius Werner
This patch adds a new --loglevel option to the CBMEM utility which can be used either numerically (e.g. `cbmem -1 --loglevel 6`) or by name (e.g. `cbmem -c --loglevel INFO`) to restrict the lines that will be printed from the CBMEM console log to a maximum loglevel. By default, using this option means that lines without a loglevel (which usually happens when payloads or other non-coreboot components add their own logs to the CBMEM console) will not be printed. Prefixing a `+` character to the option value (e.g. `--loglevel +6` or `--loglevel +INFO`) can be used to change that behavior.

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.)

2021-09-09util/cbmem: Add -2/--2ndtolast option to print second-to-last boot logJulius Werner
On some platforms, runtime firmware crashes write logs to the CBMEM console. For those, since a crash reboots the system, by the time we have a chance to run `cbmem` again the boot where the crash happened will be the one before the "last" (current) boot. So cbmem -1 doesn't show the interesting part, and cbmem -c potentially shows a lot that is cumbersome to dig through.

2017-09-28util/cbmem: be explicit about memory map sizesAaron Durbin
The cbmem utility has inherited some workarounds that originated from the default 1 MiB mapping always working. This 1 MiB mmap won't necessarily succeed if the 1 MiB encroaches on a subsequent memory range that has different cacheability. To fix this, map in only 4 KiB when the table size is not known which is the case for any forwarding entry or any low table entries on x86. That smaller mapping is then searched for a valid header. Once a valid header is found the full table is mapped and parsed allowing a forwarding entry to take precedence. Lastly, the lbtable is kept mapped in such that other operations can just operate on mapping that was previously parsed. In order to allow multiple in-flight mappings a struct mapping was added which caused the ripple within the code. However, there shouldn't be any more reasons for putting weird heuristics for when to fail. If the tables are bad then it's very much possible that mappings will fail. Retrying when the exact sizes are already known won't fix those issues.

2017-05-18cbmem_console: Improve 'cbmem -1' behavior for truncated pre-CBMEM logsJulius Werner
The 'cbmem -1' flag that cuts off console output before the last boot will ignore content from earlier stages if it was truncated due to lack of pre-CBMEM console space. This patch makes the "log truncated" message more specific and adds it as an additional cut-off marker to 'cbmem -1' to counteract that problem. Also raise the log level of the coreboot banner one step to BIOS_NOTICE to make it more likely to be included in the output for 'cbmem -1' to find. (I believe NOTICE is reasonable but I wouldn't want to go as far as WARN which should be reserved for actual problems. Of course this is not ideal, but then again, our whole log-level system really isn't... it would be better if we could make it always print a banner to the CBMEM console without affecting the UART at the same time, but that would require a larger amount of work.)

2017-05-15util/cbmem: mmap underflow on low addressesAaron Durbin
There is code to adjust the mapping down if a mmap fails at a physical address. However, if the address is less than the page size of the system then the physical offset will underflow. This can actually cause a kernel panic on when operating on /dev/mem. The failing condition happens when the requested mapping at 0 fails in the kernel. The fallback path is taken and page size is subtracted from 0 making a very large offset. The PAT code in the kernel fails with a BUG_ON in reserve_memtype() checking start >= end. The kernel needs to be fixed as well, but this fallback path is wrong as well.

2017-05-02cbmem: Add new command line flag to dump console for one boot onlyJulius Werner
Even though the persistent CBMEM console is obviously awesome, there may be cases where we only want to look at console output from the last boot. It's easy to tell where one boot ends and another begins from the banner message that coreboot prints at the start of every stage, but in order to make it easier to find that point (especially for external tools), let's put that functionality straight into the cbmem utility with a new command line flag. Use the POSIX/libc regular expression API to find the banner string for maximum compatilibity, even though it's kinda icky.

2017-04-20Turn CBMEM console into a ring buffer that can persist across rebootsJulius Werner
This patch allows the CBMEM console to persist across reboots, which should greatly help post factum debugging of issues involving multiple reboots. In order to prevent the console from filling up, it will instead operate as a ring buffer that continues to evict the oldest lines once full. (This means that if even a single boot doesn't fit into the buffer, we will now drop the oldest lines whereas previous code would've dropped the newest lines instead.) The console control structure is modified in a sorta backwards-compatible way, so that new readers can continue to work with old console buffers and vice versa. When an old reader reads a new buffer that has already once overflowed (i.e. is operating in true ring buffer mode) it will print lines out of order, but it will at least still print out the whole console content and not do any illegal memory accesses (assuming it correctly implemented cursor overflow as it was already possible before this patch). BUG=chromium:651966 TEST=Rebooted and confirmed output repeatedly on a Kevin and a Falco. Also confirmed correct behavior across suspend/resume for the latter.

2017-04-14cbmem: Add custom aligned memcpy() implementationJulius Werner
On some architectures (like AArch64), /dev/mem mappings outside of the area marked as normal RAM use a memory type that does not support unaligned accesses. The libc memcpy() implementation on these architectures may not know or expect that and make an unaligned access for certain source/dest/length alignments. Add a custom memcpy() implementation that takes these restrictions into account and use it anywhere we copy straight out of /dev/mem memory.

2016-02-22cbfs: Add LZ4 in-place decompression support for pre-RAM stagesJulius Werner
This patch ports the LZ4 decompression code that debuted in libpayload last year to coreboot for use in CBFS stages (upgrading the base algorithm to LZ4's dev branch to access the new in-place decompression checks). This is especially useful for pre-RAM stages in constrained SRAM-based systems, which previously could not be compressed due to the size requirements of the LZMA scratchpad and bounce buffer. The LZ4 algorithm offers a very lean decompressor function and in-place decompression support to achieve roughly the same boot speed gains (trading compression ratio for decompression time) with nearly no memory overhead. For now we only activate it for the stages that had previously not been compressed at all on non-XIP (read: non-x86) boards. In the future we may also consider replacing LZMA completely for certain boards, since which algorithm wins out on boot speed depends on board-specific parameters (architecture, processor speed, SPI transfer rate, etc.). BRANCH=None BUG=None TEST=Built and booted Oak, Jerry, Nyan and Falco. Measured boot time on Oak to be about ~20ms faster (cutting load times for affected stages almost in half).

2015-05-21Remove address from GPLv2 headersPatrick Georgi
As per discussion with lawyers[tm], it's not a good idea to shorten the license header too much - not for legal reasons but because there are tools that look for them, and giving them a standard pattern simplifies things. However, we got confirmation that we don't have to update every file ever added to coreboot whenever the FSF gets a new lease, but can drop the address instead. util/kconfig is excluded because that's imported code that we may want to synchronize every now and then. $ find * -type f -exec sed -i "s:Foundation, Inc., 51 Franklin St, Fifth Floor, Boston, *MA[, ]*02110-1301[, ]*USA:Foundation, Inc.:" {} + $ find * -type f -exec sed -i "s:Foundation, Inc., 51 Franklin Street, Suite 500, Boston, MA 02110-1335, USA:Foundation, Inc.:" {} + $ find * -type f -exec sed -i "s:Foundation, Inc., 59 Temple Place[-, ]*Suite 330, Boston, MA *02111-1307[, ]*USA:Foundation, Inc.:" {} + $ find * -type f -exec sed -i "s:Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA.:Foundation, Inc.:" {} + $ find * -type f -a \! -name \*.patch \ -a \! -name \*_shipped \ -a \! -name LICENSE_GPL \ -a \! -name LGPL.txt \ -a \! -name COPYING \ -a \! -name DISCLAIMER \ -exec sed -i "/Foundation, Inc./ N;s:Foundation, Inc.* USA\.* *:Foundation, Inc. :;s:Foundation, Inc. $:Foundation, Inc.:" {} + Change-Id: Icc968a5a5f3a5df8d32b940f9cdb35350654bef9 Signed-off-by: Patrick Georgi <pgeorgi@chromium.org> Reviewed-on: http://review.coreboot.org/9233 Tested-by: build bot (Jenkins) Reviewed-by: Vladimir Serbinenko <phcoder@gmail.com>

2015-04-14timestamps: You can never have enough of them!Julius Werner
Now that we have timestamps in pre-RAM stages, let's actually make use of them. This patch adds several timestamps to both the bootblock and especially the verstage to allow more fine-grained boot time tracking. Some of the introduced timestamps can appear more than once per boot. This doesn't seem to be a problem for both coreboot and the cbmem utility, and the context makes it clear which operation was timestamped at what point. Also simplifies cbmem's timestamp printing routine a bit, fixing a display bug when a timestamp had a section of exactly ",000," in it (e.g. 1,000,185). BRANCH=None BUG=None TEST=Booted Pinky, Blaze and Falco, confirmed that all timestamps show up and contained sane values. Booted Storm (no timestamps here since it doesn't support pre-RAM timestamps yet).

Commit b8ad224 changed the memory address in lb_cbmem_ref coreboot table entries from a pointer to a uint64_t. This change was introduced to make the cbmem utility work on both 32bit and 64bit userland. Unfortunately, this broke the cbmem utility running on older versions of coreboot because they were still providing a 32bit only field for the address while the cbmem utility would now take the following 4 bytes as upper 32bits of a pointer that can obviously not be mmapped. This change checks if the size of the lb_cbmem_ref structure provided by coreboot is smaller than expected, and if so, ignore the upper 32bit of the address read.

Current code outputs the whole cbmemc buffer even if only part of it is really used. Fix it to output only the used part and notify the user if the buffer was too small for the required data.

2013-01-12Implement GCC code coverage analysisStefan Reinauer
In order to provide some insight on what code is executed during coreboot's run time and how well our test scenarios work, this adds code coverage support to coreboot's ram stage. This should be easily adaptable for payloads, and maybe even romstage. See http://gcc.gnu.org/onlinedocs/gcc/Gcov.html for more information. To instrument coreboot, select CONFIG_COVERAGE ("Code coverage support") in Kconfig, and recompile coreboot. coreboot will then store its code coverage information into CBMEM, if possible. Then, run "cbmem -CV" as root on the target system running the instrumented coreboot binary. This will create a whole bunch of .gcda files that contain coverage information. Tar them up, copy them to your build system machine, and untar them. Then you can use your favorite coverage utility (gcov, lcov, ...) to visualize code coverage. For a sneak peak of what will expect you, please take a look at http://www.coreboot.org/~stepan/coreboot-coverage/ Change-Id: Ib287d8309878a1f5c4be770c38b1bc0bb3aa6ec7 Signed-off-by: Stefan Reinauer <reinauer@google.com> Reviewed-on: http://review.coreboot.org/2052 Tested-by: build bot (Jenkins) Reviewed-by: David Hendricks <dhendrix@chromium.org> Reviewed-by: Martin Roth <martin@se-eng.com> Reviewed-by: Ronald G.

2013-01-04cbmem utility: Use mmap instead of fseek/freadStefan Reinauer
The kernel on Ubuntu 12.04LTS does not allow to use fseek/fread to read the coreboot table at the end of memory but will instead abort cbmem with a "Bad Address" error. Whether that is a security feature (some variation of CONFIG_STRICT_DEVMEM) or a kernel bug is not yet clear, however using mmap works nicely.
