The pre-allocated compression buffer used for crash dumping was also being used for decompression. This isn't technically safe, since it's possible the kernel may attempt a crashdump while pstore is populating the pstore filesystem (and performing decompression). Instead, just allocate a separate buffer for decompression. Correctness is preferred over performance here. Signed-off-by: Kees Cook <keescook@chromium.org> |
