* 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.
* Fix it so uClibc returns multiple ips via h_addr_list,Eric Andersen2005-04-281-66/+117
| | | | | | | | | | | | | | | | | | | | | | | | | This fix, based on this patch http://bugs.uclibc.org/view.php?id=104 makes it so uClibc fills out round robin dns lists for applications such as nslookup: Before: $ nslookup google.com Server: mace.codepoet.org Address: 10.10.10.1 Name: google.com Address: 216.239.39.99 After: $ nslookup google.com Server: mace.codepoet.org Address: 10.10.10.1 Name: google.com Addresses: 216.239.57.99, 216.239.37.99, 216.239.39.99

| | | | | | | | | | | | | | | | | | | | 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

| | | | | | | | | | | | | | | | | | | | | Hi Erik I have corrected a bug in uClibc/libc/inet/resolv.c in function __dns_lookup(). Have attaced a txt file with my diffs regarding to uClibc 0.9.26. If two nameservers are included in /etc/resolv.conf and the first one is wrong and the secondary is correct the algorithm never looked up the secondary one. Please review my diff and feel free to submit the patch onto your CVS. If reading manual page resolv.conf(5) under nameserver and how the algorithm should work the previous dns_lookup did not fully followed that. Regards Imre Sunyi
* Implement res_search and res_querydomain based on netbsd code,Eric Andersen2004-01-041-5/+203

* Fix a long-standing bug with pthreads. A couple of linuxthreads filesManuel Novoa III2003-12-271-6/+6
| | | | | | | | | | | | | | | | were including libc-lock.h which had a bunch of weak pragmas. Also, uClibc supplied a number of no-op weak thread functions even though many weren't needed. This combined result was that sometimes the functional versions of thread functions in pthread would not override the weaks in libc. While fixing this, I also prepended double-underscore to all necessary weak thread funcs in uClibc, and removed all unused weaks. I did a test build, but haven't tested this since these changes are a backport from my working tree. I did test the changes there and no longer need to explicitly add -lpthread in the perl build for perl to pass its thread self tests.

* Patch from Jeffrey Damick:Eric Andersen2003-03-011-0/+2
| | | | | | | | With glibc if you do a res_init() that forces a reread of the nameservers file, but in uClibc the res_init will not force a reread if it has already read the file because then the nameservers value is greater than 0. So res_init must call close_nameservers() before calling open_nameservers().
