* treewide: convert bd_t to struct bd_info by coccinelleMasahiro Yamada2020-07-17489-784/+801
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Linux coding style guide (Documentation/process/coding-style.rst) clearly says: It's a **mistake** to use typedef for structures and pointers. Besides, using typedef for structures is annoying when you try to make headers self-contained. Let's say you have the following function declaration in a header: void foo(bd_t *bd); This is not self-contained since bd_t is not defined. To tell the compiler what 'bd_t' is, you need to include <asm/u-boot.h> #include <asm/u-boot.h> void foo(bd_t *bd); Then, the include direcective pulls in more bloat needlessly. If you use 'struct bd_info' instead, it is enough to put a forward declaration as follows: struct bd_info; void foo(struct bd_info *bd); Right, typedef'ing bd_t is a mistake. I used coccinelle to generate this commit. The semantic patch that makes this change is as follows: <smpl> @@ typedef bd_t; @@ -bd_t +struct bd_info </smpl> Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>

* lib: zlib: Remove offset pointer optimization in inftrees.cChin Liang See2020-07-171-11/+8
| | | | | | | | | | | | | | | | | | | This fixes the CVE-2016-9840. Commit imported from [1]. inftrees.c was subtracting an offset from a pointer to an array, in order to provide a pointer that allowed indexing starting at the offset. This is not compliant with the C standard, for which the behavior of a pointer decremented 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 tiny optimization was removed, in order to avoid the possibility of undefined behavior.

| | | | | | | | | | | | | | | - Despite other ext4 filesystem functions, ext4fs_mount returns 0 in case of error. - This leads to u-boot crash in case that an SD card with valid partition table but without ext4 filesystem created in a partition is found on SD card. - Fix this by returning a proper error code of '-1' from spl_load_image_ext function in case of ext4fs_mount error.

* lz4: fix decompressor on big-endian powerpcRasmus Villemoes2020-07-171-56/+39
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Booting an lz4-compressed kernel image fails on our powerpc board with -EPROTONOSUPPORT. Adding a bit of debug prints, we get magic: 0x184d2204 flags: 0x64 reserved0: 1 has_content_checksum: 1 has_content_size: 0 has_block_checksum: 0 independent_blocks: 1 version: 0 block_descriptor: 70 reserved1: 7 max_block_size: 0 reserved2: 0 So the magic is ok, but the version check fails, also some reserved bits are apparently set. But that's because the code interprets the "flags" and "block_descriptor" bytes wrongly: Using bit-fields to access individual bits of an "on the wire" format is not portable, not even when restricted to the C flavour implemented by gcc. Quoting the gcc manual: * 'The order of allocation of bit-fields within a unit (C90 6.5.2.1, C99 and C11 6.7.2.1).' Determined by ABI. and indeed, the PPC Processor ABI supplement says * Bit-fields are allocated from right to left (least to most significant) on Little-Endian implementations and from left to right (most to least significant) on Big-Endian implementations. The upstream code (github.com/lz4/lz4) uses explicit shifts and masks for encoding/decoding: /* FLG Byte */ *dstPtr++ = (BYTE)(((1 & _2BITS) << 6) /* Version('01') */ + ((cctxPtr->prefs.frameInfo.blockMode & _1BIT ) << 5) + ((cctxPtr->prefs.frameInfo.blockChecksumFlag & _1BIT ) << 4) + ((unsigned)(cctxPtr->prefs.frameInfo.contentSize > 0) << 3) + ((cctxPtr->prefs.frameInfo.contentChecksumFlag & _1BIT ) << 2) + (cctxPtr->prefs.frameInfo.dictID > 0) ); /* Flags */ { U32 const FLG = srcPtr[4]; U32 const version = (FLG>>6) & _2BITS; blockChecksumFlag = (FLG>>4) & _1BIT; blockMode = (FLG>>5) & _1BIT; contentSizeFlag = (FLG>>3) & _1BIT; contentChecksumFlag = (FLG>>2) & _1BIT; dictIDFlag = FLG & _1BIT; /* validate */ if (((FLG>>1)&_1BIT) != 0) return err0r(LZ4F_ERROR_reservedFlag_set); /* Reserved bit */ if (version != 1) return err0r(LZ4F_ERROR_headerVersion_wrong); /* Version Number, only supported value */ } Do the same here, and while at it, be more careful to use unaligned accessors to what is most likely unaligned. Also update the comment to make it clear that it only refers to the lz4.c file, not the following code of lz4_wrapper.c. This has been tested partly, of course, by seeing that my lz4-compressed kernel now boots, partly by running the (de)compression test-suite in the (x86_64) sandbox - i.e., it should still work just fine on little-endian hosts.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The FSP-S changes the ITSS priorities. The code that tries to save it before running FSP-S and restore it afterwards does not work as U-Boot relocates in between the save and restore. This means that the driver data saved before relocation is lost and the new driver just sees zeroes. Fix this by allocating space in the relocated memory for the ITSS data. Save it there and access it from the driver after relocation. This fixes interrupt handling on coral. Also drop the log_msg_ret() in irq_first_device_type() since this function can be called speculatively in places where we are not sure if there is an interrupt controller of that type. The resulting log errors are confusing when there is no error.
