libc-a-y for objects that go into static libs, changing their suffix to .os, of they should be PIC

archs lack proper crt1. The Makefiles in extra/scripts are intended to be linked into each dir, where it is necessary to build locally.

addr.c also as int. Rename mylock/LOCK/UNLOCK in resolv.c to allow IMA compiling

objects at once; use :=//$</$^; use CRT_SRC/CRT_OBJ/SCRT_OBJ/CSRC/COBJ/SSRC/SOBJ/MSRC/MOBJ where no more is needed, if only CSRC is present use OBJS directly instead of COBJ; CTOR_TARGETS are created directly in lib; remove unused/unneeded parts. Hope I haven't broken too much.

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.

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

... so dont try using socketcall() unless the system call exists

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.

Most of the time, no one ever notices, so there's not point eh ? Also
standardize tab usage.

adding cruft to include/sys/time.h. But also, there's no sense in
making changes like this until we decide how we're going to approach
the hidden symbol transition.

Hello!
Would the attached patch be acceptable (maybe instead of
__libc_gettimeofday using __gettimeofday)
We have some issues, see

was playing around with the source today and eventually the obvious answer hit
me ... while read_etc_hosts_r() generatings an array of strings fo h_aliases
and populates it, the dns path does not :)
find attached a patch that'll actually generate the h_aliases list in the
normal dns code path ... i used the etc_hosts_r() code as a template for some
of it ...
note that this is just a simple fix ... it fills the alias list with just the
hostname gethostbyname_r was passed ... the proper fix i think would be to
parse the dns packet down in __dns_lookup() and pass the info back via the
resolv_answer struct ...
but this fix is better than the current state of things ... that is, h_aliases
currently is never initailized in the dns code path :)

Rather than copy more code back into the bridge-utilities, how about applying this
change to uClibc? I hate when packages get cluttered for workarounds for other
incompatibilities.
The problem is that SIOCGIFCONF only lists interfaces that have IP addresses, so it
doesn't find the other interfaces that are being used for bridging. It could be fixed
in the kernel to return all interfaces, but then something else might break; and still
it mean a kernel update for the 2.4 users.
The whole use of ifindex in the bridge API is a bad idea. But we probably have to live
with it for compatibility.
Patch against uClibc 0.9.26

Hi Erik
It seems to me that __pthread_once and __pthread_initialize_minimal could be made
WEAKs with no stub. The code in rpc_thread.c and __uClibc_main.c appears to expect this.
Also, __pthread_return_0 __pthread_return_1 and __pthread_return_void can be static, not to
pollute the name space.

is not a SuSv3 symbol). Rather than using __bzero internally per Alexandre's
original patch, use memset instead.

instead. Based on an initial patch from Tobias Anderberg, but reworked. I
asked Tobias to look into doing something more like what is done in busybox,
but that proved to be a pain.
One possible concern is that these buffers will probably show up as
memory leaks i.e. with valgrind. Perhaps we should add in an atexit
call to free this memory right after we allocate it?

Bug fix: gethostbyname_r checked errno without first setting it to a
known value.

While testing the FR-V code with GCC mainline, I ran into some
problems in the RPC code. It relies on a GCC extension that is no
longer available, namely, the result of a cast is no longer considered
an lvalue.
This patch enables the code to compile. I haven't been able to test
RPC though, especially in a multi-threaded environment.

Codepaths streamlined. Improved performance for nonthreaded apps
when linked with a thread-enabled libc.
Minor iconv bug and some locale/thread related startup issues fixed.
These showed up in getting a gcj-compiled java helloworld app running.
Removed some old extension functions... _stdio_fdout and _stdio_fsfopen.

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.

but remove support for host aliases (the HOSTALIASES env variable)
which looks like a very bad idea.

support) which could cause things like EOF and read errors while reading
/etc/services to always return a TRY_AGAIN. The perl test suite would alloc a
larger buffer and try again until all memory was exhausted. When we get a read
error, or EOF, it means we didn't get what we wanted, and so we should return
an error. Doing so fixes the failing perl 5.8.2 test.

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.
