Subject: [PATCH] Detail.c: do not skip first character when calling xstrdup in
Detail()
Git-commit: Posted but not upstreamed yet
References: bsc#1123814
'Commit b9c9bd9bacaa ("Detail: ensure --export names are acceptable as
shell variables")' duplicates mdi->sys_name to sysdev string by,
char *sysdev = xstrdup(mdi->sys_name + 1);
which skips the first character of mdi->sys_name. Then when running
mdadm --detail <md device> --export, the output looks like,
MD_DEVICE_ev_sda2_ROLE=1
MD_DEVICE_ev_sda2_DEV=/dev/sda2
The first character of md device (between MD_DEVICE and _ROLE/_DEV)
is dropped. The expected output should be,
MD_DEVICE_dev_sda2_ROLE=1
MD_DEVICE_dev_sda2_DEV=/dev/sda2
This patch removes the '+ 1' from calling xstrdup() in Detail(), which
gets the dropped first character back.
