Subject: fix regression in getspnam[_r] error code for insufficient buffer size
X-Git-Tag: v1.1.17~51
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=91d34c4533e6bf6eacad7a9f001f28f9e5ebc656;p=oweals%2Fmusl.git

fix regression in getspnam[_r] error code for insufficient buffer size

commit 2d7d05f031e014068a61d3076c6178513395d2ae wrongly changed ERANGE
to EINVAL, likely as the result of copy-and-paste error.
