Subject: transport-helper: use xread instead of read
X-Git-Tag: v2.21.0-rc0~90^2~4
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=c14e5a1a5018f4407390488dfea387e5dc81c817;p=thirdparty%2Fgit.git

transport-helper: use xread instead of read

This fix was needed on HPE NonStop NSE and NSX where SSIZE_MAX is less than
BUFFERSIZE resulting in EINVAL. The call to read in transport-helper.c
was the only place outside of wrapper.c where it is used instead of xread.
