| | | | | | | | MontaVista noticed that when their kernels were configured to trap on unaligned access gethostbyname_r could mysteriously crash. I tracked this down to an unaligned buffer being passed to gethostbyname_r from some other part of uClibc (afraid I don't remember where from any more). We have to pad the beginning of the buffer to a pointer alignment before we store pointers in it.
* This patch will fix a problem when the same host is defined with both IPv4 andMike Frysinger2007-09-281-2/+8
| | | | | | | | | | | | IPv6 entries in /etc/hosts. Previous only the first of these host would work, as uClibc would read the /etc/hosts file from top to bottom, failing if the first hit did not match the IP type. Now uClibc will continue reading, even if the first correct entry name, but wrong IP type fails. Thus, allowing a second correct entry name with correct IP type will result in a name resolve.

| | | | | | I have successfully made gethostbyname_r(), res_init(), and gethostid() fully reentrant. In addition, I have added a NULL check to inet_aton(). This is where SEG FAULTs were coming from when gethostbyname_r() was called.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Hi Erik, Thanks for all your great work. I found a set of bugs in resolv.c . Basically, there is code that looks like: BIGLOCK; __nameserversXX=__nameservers; __nameserverXX=__nameserver; BIGUNLOCK; i = __dns_lookup(dname, type, __nameserversXX, __nameserverXX, &packet, &a); which is a problem because the declarations are int __nameservers; char * __nameserver[MAX_SERVERS]; int __searchdomains; char * __searchdomain[MAX_SEARCH]; so you can see that __nameserver is a pointer. Copying the pointer to __nameserverXX doesn't protect the global variable space. I have attached a patch and the new file. I hope you will incorporate these bug fixes. I spent quite a bit of time tracking them down. Many thanks, Ron
* fix obvious bug in ipv4/ipv6 resolving. When not using AF_INET,Eric Andersen2007-02-021-1/+1
| | | | | | gethostbyname2_r tries to resolve an ipv6 address from /etc/hosts using get_hosts_byname_r, but with AF_INET instead of the supplied address family. This returns ipv4 addresses marked as ipv6 ones. Fix from nbd.

* Major cleanup of internal mutex locking. Be more consistant in how we doEric Andersen2006-12-071-321/+314
| | | | | | | things, and avoid potential deadlocks caused when a thread holding a uClibc internal lock get canceled and terminates without releasing the lock. This change also provides a single place, bits/uClibc_mutex.h, for thread libraries to modify to change all instances of internal locking.
* fix h_alias handling in gethostbyaddr_r() just like in gethostbyname_r()Mike Frysinger2006-07-311-0/+11

* The default static buffer sizes are too small to handle the 8 entries returnedEric Andersen2005-05-101-5/+5
| | | | | | | | | | | by 'nslookup www.yahoo.com' and 'nslookup mail.hotmail.com', and thus we currently return ERANGE when trying to lookup some of the most popular hosts on the planet. Whether these sites deserve to be popular is a question I'll leave for someone else to worry about. This change makes certain we have enough static buffer space to handle about 21 IPv4 IP address replies per DNS query. Far more than enough to handle common cases such as www.yahoo.com and mail.hotmail.com.

* Jan Lana writes:Eric Andersen2005-01-111-11/+12
| | | | | | | | | | | | | | | | | | | | uClibc resolver doesn't lookup all search domains. For example, if you have computer 'jenda.prague.my.cz' and resolv.conf: search my.cz nameserver xx.xx.xx.xx try this: ping jenda.prague.my.cz #works ping jenda.prague #unknown host libc/inet/resolv.c doesn't want to try search domains if the domain name contains '.'. I don't find any reason for the behaviour in literature and it is inconsistent with the glibc. Patch is attached. regards, - jenda
