2024-05-24capsule: fwu: transition the platform state on a successful updateSughosh Ganu
Transition the platform to either Trial State or Regular State on a successful update. Do this by calling the fwu_state_machine_updates() API function. For version 1 of the FWU metadata, the transition to Trial State is done by starting the Trial State counter, while for version 2, in addition to the counter, the bank_state field of the FWU metadata is also updated to Valid. For transitioning the platform to Regular State, no action is needed with version 1 of the FWU metadata structure, while for version 2, the bank_state field is set to Accepted.

2024-05-24fwu: metadata: add functions for handling version specific metadata fieldsSughosh Ganu
Support is being added in U-Boot for version 2 of the FWU metadata. Support for this version is to co-exist with version 1 support. To achieve this, a common, version agnostic structure has been added to keep information provided by the FWU metadata structure. Add API's to handle the version specific FWU metadata fields. The version agnostic structure gets initialized at boot by reading the FWU metadata. Updates to the FWU metadata result in the API's getting called to populate the version specific fields of the strucure, before the metadata gets written to the storage media.

2024-04-20efi_loader: add an EFI variable with the file contentsIlias Apalodimas
Previous patches enabled SetVariableRT using a RAM backend. Although EBBR [0] defines a variable format we can teach userspace tools and write the altered variables, it's better if we skip the ABI requirements completely. So let's add a new variable, in its own namespace called "VarToFile" which contains a binary dump of the updated RT, BS and, NV variables and will be updated when GetVariable is called. Some adjustments are needed to do that. Currently we discard BS-only variables in EBS(). We need to preserve those on the RAM backend that exposes the variables. Since BS-only variables can't appear at runtime we need to move the memory masking checks from efi_var_collect() to efi_get_next_variable_name_mem()/ efi_get_variable_mem() and do the filtering at runtime. We also need an efi_var_collect() variant available at runtime, in order to construct the "VarToFile" buffer on the fly. All users and applications (for linux) have to do when updating a variable is dd that variable in the file described by "RTStorageVolatile". Linux efivarfs uses a first 4 bytes of the output to represent attributes in little-endian format. So, storing variables works like this: $~ efibootmgr -n 0001 $~ dd if=/sys/firmware/efi/efivars/VarToFile-b2ac5fc9-92b7-4acd-aeac-11e818c3130c of=/boot/efi/ubootefi.var skip=4 bs=1 [0] https://arm-software.github.io/ebbr/index.html#document-chapter5-variable-storage Suggested-by: Ard Biesheuvel <[email protected]> # dumping all variables to a variable Co-developed-by: Heinrich Schuchardt <[email protected]> # contributed on efi_var_collect_mem() Signed-off-by: Heinrich Schuchardt <[email protected]> Signed-off-by: Ilias Apalodimas <[email protected]>
2024-04-20efi_loader: Add OS notifications for SetVariable at runtimeIlias Apalodimas

2024-04-20efi_loader: conditionally enable SetvariableRTIlias Apalodimas
When we store EFI variables on file we don't allow SetVariable at runtime, since the OS doesn't know how to access or write that file. At the same time keeping the U-Boot drivers alive in runtime sections and performing writes from the firmware is dangerous -- if at all possible. For GetVariable at runtime we copy runtime variables in RAM and expose them to the OS. Add a Kconfig option and provide SetVariable at runtime using the same memory backend. The OS will be responsible for syncing the RAM contents to the file, otherwise any changes made during runtime won't persist reboots. It's worth noting that the variable store format is defined in EBBR [0] and authenticated variables are explicitly prohibited, since they have to be stored on a medium that's tamper and rollback protected. - pre-patch $~ mount | grep efiva efivarfs on /sys/firmware/efi/efivars type efivarfs (ro,nosuid,nodev,noexec,relatime) $~ efibootmgr -n 0001 Could not set BootNext: Read-only file system - post-patch $~ mount | grep efiva efivarfs on /sys/firmware/efi/efivars type efivarfs (rw,nosuid,nodev,noexec,relatime) $~ efibootmgr -n 0001 BootNext: 0001 BootCurrent: 0000 BootOrder: 0000,0001 Boot0000* debian HD(1,GPT,bdae5610-3331-4e4d-9466-acb5caf0b4a6,0x800,0x100000)/File(EFI\debian\grubaa64.efi) Boot0001* virtio 0 VenHw(e61d73b9-a384-4acc-aeab-82e828f3628b,0000000000000000)/VenHw(e61d73b9-a384-4acc-aeab-82e828f3628b,850000001f000000)/VenHw(e61d73b9-a384-4acc-aeab-82e828f3628b,1600850000000000){auto_created_boot_option} $~ efivar -p -n 8be4df61-93ca-11d2-aa0d-00e098032b8c-BootNext GUID: 8be4df61-93ca-11d2-aa0d-00e098032b8c Name: "BootNext" Attributes: Non-Volatile Boot Service Access Runtime Service Access Value: 00000000 01 00 FWTS runtime results Skipped tests are for SetVariable which is now supported 'Passed' test is for QueryVariableInfo which is not yet supported Test: UEFI miscellaneous runtime service interface tests.

The first two patches are just preparation based on changes which happened in past. The third one is actual fix and the last one is following what has been done in Linux kernel long time ago and don't use incorrect zlib version string. I tested it with and I can't see any issue. ./test/py/test.py --bd sandbox --build -s And gitlab CI is also not showing any issue.
2024-04-12zlib: Remove incorrect ZLIB_VERSIONMichal Simek
Get rid of zlib version which is not correct because of U-Boot related changes and various CVE backports. The change in inspired by Linux kernel commit 4f3865fb57a0 ("[PATCH] zlib_inflate: Upgrade library code to a recent version") which described ZLIB_VERSION removal as "This patch also removes ZLIB_VERSION as it no longer has a correct value. We don't need version checks anyway as the kernel's module handling will take care of that for us. This removal is also more in keeping with the zlib author's wishes (http://www.zlib.net/zlib_faq.html#faq24) and I've added something to the zlib.h header to note its a modified version." Author describes wish to follow this guidance at https://www.zlib.net/zlib_faq.html#faq24: "The license says that altered source versions must be "plainly marked". So what exactly do I need to do to meet that requirement? You need to change the ZLIB_VERSION and ZLIB_VERNUM #defines in zlib.h. In particular, the final version number needs to be changed to f, and an identification string should be appended to ZLIB_VERSION. Version numbers x.x.x.f are reserved for modifications to zlib by others than the zlib maintainers. For example, if the version of the base zlib you are altering is 1.2.3.4, then in zlib.h you should change ZLIB_VERNUM to 0x123f, and ZLIB_VERSION to something like 1.2.3.f-zachary-mods-v3. You can also update the version strings in deflate.c and inftrees.c." But U-Boot is not exact version that's why following the same style which has been used by Linux kernel where ZLIB_VERSION is completely removed. Signed-off-by: Michal Simek <[email protected]>
2024-04-12zlib: Port fix for CVE-2016-9841 to U-BootMichal Simek
The patch corresponds to zlib commit at https://github.com/madler/zlib/commit/9aaec95e82117c1cb0f9624264c3618fc380cecb which declares that it is fixing CVE-2016-9841. Here is c&p description from zlib: "Use post-increment only in inffast.c. An old inffast.c optimization turns out to not be optimal anymore with modern compilers, and furthermore was not compliant with the C standard, for which decrementing a pointer before its allocated memory is undefined. Per the recommendation of a security audit of the zlib code by Trail of Bits and TrustInSoft, in support of the Mozilla Foundation, this "optimization" was removed, in order to avoid the possibility of undefined behavior." Origin patch also updates the code when INFLATE_ALLOW_INVALID_DISTANCE_TOOFAR_ARRR is present but this code is not the part of U-Boot hence it is ignored. Also do not deal with state->sane variable which requires other changes which are also not the part of zlib.

Since UEFI specification does not clearly describe the behavior of the append write to non-existent variable, let's update the U-Boot file storage implementation to get aligned with the EDK II reference implementation.
