We have the following warnings when compiling uncrypt on LP64 (e.g.
aosp_angler-userdebug).
bootable/recovery/uncrypt/uncrypt.cpp:77:53: warning: format specifies type 'long long' but the argument has type 'off64_t' (aka 'long') [-Wformat]
ALOGE("error seeking to offset %lld: %s\n", offset, strerror(errno));
~~~~ ^~~~~~
%ld
bootable/recovery/uncrypt/uncrypt.cpp:84:54: warning: format specifies type 'long long' but the argument has type 'unsigned long' [-Wformat]
ALOGE("error writing offset %lld: %s\n", (offset + written), strerror(errno));
~~~~ ^~~~~~~~~~~~~~~~~~
%lu
bootable/recovery/uncrypt/uncrypt.cpp:246:16: warning: comparison of integers of different signs: 'size_t' (aka 'unsigned long') and 'off_t' (aka 'long') [-Wsign-compare]
while (pos < sb.st_size) {
~~~ ^ ~~~~~~~~~~
According to POSIX spec [1], we have:
off_t and blksize_t shall be signed integer types;
size_t shall be an unsigned integer type;
blksize_t and size_t are no greater than the width of type long.
And on Android, we always have a 64-bit st_size from stat(2)
(//bionic/libc/include/sys/stat.h).
Fix the type and add necessary casts to suppress the warnings.
