If MODE is GAI_WAIT wait until all > netdb.h: requests are handled. If WAIT is GAI_NOWAIT return immediately after I downloaded glibc-2.2.5 yesterday to take a look. There is an "interesting" comment in glibc-2.2.5/include/netdb.h, followed by all the missing AI_ macro definitions: "/* The following declarations and definitions have been removed from the public header since we don't want people to use them. */" All of these are now included in /usr/include/netdb.h with no qualification whatever, so at some point the glibc maintainers changed their mind about this. Likely the correct fix for this is to restore the old nfs_gethostbyname() and have ./configure detect the presence of these AI_ macros. If they are not present, use the original function. If they are, use the new one. Alternately, we can define these in utils/mount/network.c if they are not already defined. This would work if the actual value of these macros has not changed over time. I'll post a proposed fix as soon as I can, but some research will be required to figure out why these were banned originally. -- Chuck Lever -- To unsubscribe from this list: send the line "unsubscribe linux-nfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
