Subject: [PATCH] fix errno not being set to ERANGE by getgr, getpw, and getspnam
Hi,
currently, the getgr, getpw, and getspnam functions in musl return ERANGE
when the allocated buffer is not large enough, but do not set errno to the
same value. This causes issues with utilities, for example the "shadow"
utilities (useradd/mod, groupmod, etc.) which assume this behaviour (which
at least gnu libc exhibits) and leads to groups having a small limit on the
number of members.
The attached patch, against 1.1.16, corrects this.
Cheers,
Rudolph
