            Bug ID: 69771
           Summary: crypt may return EPERM and/or EINVAL
           Product: Documentation
           Version: unspecified
          Hardware: All
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P1
         Component: man-pages
          Assignee: documentation_man-pages-ztI5WcYan/vQLgFONoPN62D2FQJk+8+b@public.gmane.org
          Reporter: kosaki.motohiro-+CUm20s59erQFUHtdCDX3A@public.gmane.org
        Regression: No

http://man7.org/linux/man-pages/man3/crypt.3.html

crypt(3) man page only has a description about ENOSYS. However current glibc
may return EPERM and EINVAL too.
I'd suggest to add following description

EPERM: If /proc/sys/crypto/fips_enabled is turned on and try to use weak crypt
type, such as DES.
EINVAL: salt argument has wrong format.


Thanks.

Thanks, for the report Motohiro. I added these texts:

       EINVAL salt has the wrong format.

       EPERM  /proc/sys/crypto/fips_enabled has a nonzero value, and an
              attempt  was  made to use a weak encryption type, such as
              DES.

Okay?

Just for future reports: to help me verify details, pointers to the relevant
source files would save me doing some hunting. (I did find them after a little
searching, in this case)

Oops. Sorry about that. Yes, I'll do that.
