Subject: Re: util-linux-2.23 mount segmentation fault error
util-linux-2.23 mount segfault error seems to be solved.
no more segfault error, when i test mount binary.
i modified follow macros in musl /include/bits/ioctl.h and musl libc
reinstalled.
- #define _IOR(a,b,c) _IOC(2,(a),(b),sizeof(c))
- #define _IOWR(a,b,c) _IOC(3,(a),(b),sizeof(c))
+ #define _IOR(a,b,c) _IOC(2U,(a),(b),sizeof(c))
+ #define _IOWR(a,b,c) _IOC(3U,(a),(b),sizeof(c))
other points just removed some warings.
ex)
, ino); to , (uintmax_t) ino); // etc
build log attached.
TIA
