2018-12-03rsa: add support of padding pssPhilippe Reynes
We add the support of the padding pss for rsa signature. This new padding is often recommended instead of pkcs-1.5. Signed-off-by: Philippe Reynes <philippe.reynes@softathome.com> Reviewed-by: Simon Glass <sjg@chromium.org>
2018-12-03rsa: add a structure for the paddingPhilippe Reynes
The rsa signature use a padding algorithm. By default, we use the padding pkcs-1.5. In order to add some new padding algorithm, we add a padding framework to manage several padding algorithm. The choice of the padding is done in the file .its. Signed-off-by: Philippe Reynes <philippe.reynes@softathome.com> Reviewed-by: Simon Glass <sjg@chromium.org>
2018-12-03rsa: use new openssl API to create signaturePhilippe Reynes

2018-12-03efi_loader: bootmgr: add load option helper functionsAKASHI Takahiro
In this patch, helper functions for an load option variable (BootXXXX) are added: * efi_deserialize_load_option(): parse a string into load_option data (renamed from parse_load_option and exported) * efi_serialize_load_option(): convert load_option data into a string Those functions will be used to implement efishell command.

2018-12-03efi_loader: allow device == NULL in efi_dp_from_name()AKASHI Takahiro

2018-12-02efi_loader: Align runtime section to 64kbAlexander Graf
The UEFI spec mandates that runtime sections are 64kb aligned to enable support for 64kb page size OSs. This patch ensures that we extend the runtime section to 64kb to be spec compliant. Signed-off-by: Alexander Graf <agraf@suse.de>

2018-12-02efi_loader: fix simple network protocolHeinrich Schuchardt
We should not call eth_rx() before the network interface is initialized. The services of the simple network protocol should check the state of the network adapter. Add and correct comments. Without this patch i.mx6 system Wandboard Quad rev B1 fails to execute bootefi selftest. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de> Signed-off-by: Alexander Graf <agraf@suse.de>
2018-12-02efi_loader: correctly aligned transmit bufferHeinrich Schuchardt
Calling net_send_packet() requires that the buffer is aligned to a multiple of PKTALIGN (= ARCH_DMA_MINALIGN). The UEFI spec does not require efi_net_transmit() to be called with a buffer with any special alignment. So we have to copy to an aligned buffer. The current coding copies to an aligned buffer only if CONFIG_EFI_LOADER_BOUNCE_BUFFER=y. Many boards like the Odroid C2 do not use a bounce buffer. With the patch we copy to a correctly aligned buffer in all cases. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de> Signed-off-by: Alexander Graf <agraf@suse.de>

2018-12-02efi_selftest: check fdt is marked as runtime dataHeinrich Schuchardt

2018-12-02fdt: sandbox: correct use of ${fdtcontroladdr}Heinrich Schuchardt
The sandbox uses a virtual address space that is neither the physical nor the virtual address space of the operating system. All address used on the command line live in this address space. So also the environment variable ${fdtcontroladdr} has to be in this address space. Commands like bootefi and booti receive the fdt address as parameter. Without the patch ${fdtcontroladdr} cannot be used as parameter value on the sandbox. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de> Signed-off-by: Alexander Graf <agraf@suse.de>
2018-12-02efi_loader: macro efi_size_in_pages()Heinrich Schuchardt

2018-12-02efi_loader: eliminate sandbox addressesHeinrich Schuchardt
Do not use the sandbox's virtual address space for the internal structures of the memory map. This way we can eliminate a whole lot of unnecessary conversions. The only conversion remaining is the one when adding known memory. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de> Signed-off-by: Alexander Graf <agraf@suse.de>
2018-12-02efi_loader: Reserve unaccessible memoryAlexander Graf
On some systems, not all RAM may be usable within U-Boot. Maybe the memory maps are incomplete, maybe it's used as workaround for broken DMA. But whatever the reason may be, a platform can say that it does not wish to have its RAM accessed above a certain address by defining board_get_usable_ram_top(). In the efi_loader world, we ignored that hint, mostly because very few boards actually have real restrictions around this. So let's honor the board's wish to not access high addresses during boot time. The best way to do so is by indicating the respective pages as "allocated by firmware". That way, Operating Systems will still use the pages after boot, but before boot no allocation will use them.

2018-12-02efi_loader: do not use unsupported printf codeHeinrich Schuchardt

2018-12-02efi_loader: Ensure memory allocations are page alignedAlexander Graf
When the max_addr parameter of efi_find_free_memory() is within bounds of an existing map and fits the reservation, we just return that address as allocation value. That breaks however if max_addr is not page aligned. So ensure that it always comes to us page aligned, simplifying the allocation logic. Without this, I've seen breakage where we were allocating pages at -1U (32bit) which fits into a region that spans beyond 0x100000000. In that case, we would return 0xffffffff as a valid memory allocation, although we usually do guarantee they are all page aligned. Fix this by aligning the max address argument always.

2018-12-02efi_loader: Handle RELA absolute relocations properlyAlexander Graf
With RELA absolute relocations, the relocation target contains our link offset which we need to remove from the equation again. We did this properly in the relative relocation path, but not in the absolute one. So let's do this for the absolute one as well. That way, u-boot can have a TEXT_OFFSET of != 0 and still relocate itself properly. This fixes a bug where efi_loader did not work on the RISC-V QEMU port. With this patch, I can successfully run UEFI applications on the RISC-V QEMU port.

2018-11-20fdt: Fix uncompress_blob() for U-Boot properMarek Vasut
When U-Boot proper is compiled with CONFIG_MULTI_DTB_FIT and tries to call uncompress_blob(), it fails with -ENOTSUPP. This is because the full implementation of this function which includes compression is available only in SPL. In U-Boot proper or if the compression is not enabled, the blob is not compressed and thus can be passed to locate_dtb_in_fit() in fdtdec_setup() without any changes. Pass the blob without any changes if compression is not enabled instead of failing.

2018-11-16fdt_region: Ensure that depth never goes below -1Konrad Beckmann
A specially crafted FIT image makes it possible to overflow the stack with controlled values when using the verified boot feature. Depending on the memory layout, this could be used to overwrite configuration variables on the heap and setting them to 0, e.g. disable signature verification, thus bypassing it. This change fixes a bug in fdt_find_regions where the fdt structure is parsed. A lower value than -1 of depth can lead to a buffer underflow write on the stack.

2018-11-14sysreset: Remove DM_FLAG_PRE_RELOC flag in various driversBin Meng
When a driver declares DM_FLAG_PRE_RELOC flag, it wishes to be bound before relocation. However due to a bug in the DM core, the flag only takes effect when devices are statically declared via U_BOOT_DEVICE(). This bug has been fixed recently by commit "dm: core: Respect drivers with the DM_FLAG_PRE_RELOC flag in lists_bind_fdt()", but with the fix, it has a side effect that all existing drivers that declared DM_FLAG_PRE_RELOC flag will be bound before relocation now. This may expose potential boot failure on some boards due to insufficient memory during the pre-relocation stage. To mitigate this potential impact, the following changes are implemented: - Remove DM_FLAG_PRE_RELOC flag in the driver, if the driver only supports configuration from device tree (OF_CONTROL) - Keep DM_FLAG_PRE_RELOC flag in the driver only if the device is statically declared via U_BOOT_DEVICE() - Surround DM_FLAG_PRE_RELOC flag with OF_CONTROL check, for drivers that support both statically declared devices and configuration from device tree Signed-off-by: Bin Meng <bmeng.cn@gmail.com> Reviewed-by: Simon Glass <sjg@chromium.org>
