2017-06-15set errno when getpw*_r, getgr*_r, and getspnam_r failRich Felker-0/+1
these functions return an error code, and are not explicitly documented to set errno, but they are nonstandard and the historical implementations do set errno as well, and some applications expect this behavior. do likewise for compatibility. patch by Rudolph Pereira.
2015-02-23fix crashes in refactored passwd/group codeRich Felker-2/+2
the wrong condition was used in determining the presence of a result that needs space/copying for the _r functions. a zero return value does not necessarily mean success; it can also be a non-error negative result: no such user/group.

2013-09-29fix off-by-one error in getgrnam_r and getgrgid_r, clobbering gr_nameRich Felker-2/+2
bug report and patch by Michael Forney. the terminating null pointer at the end of the gr_mem array was overwriting the beginning of the string data, causing the gr_name member to always be a zero-length string.
