Subject: tst-*glob*: Do not check d_name size
X-Git-Tag: glibc-2.39~533
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=5e4435f960bb681cbea853fb41043fabeeaea1b4;p=thirdparty%2Fglibc.git

tst-*glob*: Do not check d_name size

Posix says that d_name is of unspecified size, and sizeof(d_name)
should not be used. It is indeed only 1-byte long in bits/dirent.h. We
can instead explictly provide the actual allocated size to
__strcpy_chk.
