crypto: lzo - Fix compression buffer overrun [ Upstream commit cc47f07234f72cbd8e2c973cdbf2a6730660a463 ] Unlike the decompression code, the compression code in LZO never checked for output overruns. It instead assumes that the caller always provides enough buffer space, disregarding the buffer length provided by the caller. Add a safe compression interface that checks for the end of buffer before each write. Use the safe interface in crypto/lzo.

move asm/unaligned.h to linux/unaligned.h asm/unaligned.h is always an include of asm-generic/unaligned.h; might as well move that thing to linux/unaligned.h and include that - there's nothing arch-specific in that header. auto-generated by the following: for i in git grep -l -w asm/unaligned.h; do sed -i -e "s/asm\/unaligned.h/linux\/unaligned.h/" $i done for i in git grep -l -w asm-generic/unaligned.h; do sed -i -e "s/asm-generic\/unaligned.h/linux\/unaligned.h/" $i done git mv include/asm-generic/unaligned.h include/linux/unaligned.h git mv tools/include/asm-generic/unaligned.h tools/include/linux/unaligned.h sed -i -e "/unaligned.h/d" include/asm-generic/Kbuild sed -i -e "s/__ASM_GENERIC/__LINUX/" include/linux/unaligned.h tools/include/linux/unaligned.h | 1 年前 | |
lib/lzo: separate lzo-rle from lzo To prevent any issues with persistent data, separate lzo-rle from lzo so that it is treated as a separate algorithm, and lzo is still available.
