[Buildroot] Some AT91SAM9261-EK Notes

[Quick X]

I was updating/testing some versions of things and noticed three small issues.
 
First: Using the "uClibc-0.9.30.config" file segfaults some packages, for example dropbear and samba.
 
---at91sam9261ek_defconfig---  Works Fine
uClibc 0.9.30 (uClibc-0.9.29.config)
binutils 2.18
gcc 4.2.4

u-boot-2009.01
 
---Attempted 1---  Compiles but some Packages Don't work

As you can see only the uClibc-0.9.30.config was changed to get it working.  When I say doesn't work I mean error messages during Boot (Seg Fault and Core Dump).  IE

Second: I was able to test the "save config" using a custom linux config.  This works now as long as you use "save config" (because it sets the "BOARD_PATH" as well as the "BR2_LINUX_KCONFIG").  If you manually set the Linux Config file with a "make menuconfig", then you also have to manually set the "make menuconfig> XXX> Atmel board repository".  Maybe intended but took me a little bit to figure out.

Can you  build uclibc-0.9.30 with ?uclibc-0.9.29.config without
updating configuration item.

Maybe you can provide a diff between the resulting .config
and the ?uclibc-0.9.30.config

I built the project with uClibc-0.9.30 (0.9.29.config), and then build 
project with uClibc-0.9.30 (0.9.30.config).  Here are the differences in the 
generated "toolchain_build_arm/uClibc-0.9.30/.config"'s.  I TABed the Items 
that didn't show up in the counterpart config.

My guess is that it's the "UCLIBC_USE_NETLINK" option since it looks like 
only networky applications are affected (dropbear, samba, etc).  I'm 
actually catching a plane in 8 hours and will be gone for a week, however, I 
can try to test the options one by one if you can't tell what it is from 
just the diff.

I also attached both the generated config files if they are helpful.  I 
wasn't too sure what "without updating configuration items" meant, is it an 
option somewhere?

You're not the only one having problems with uclibc 0.9.30 and
netlink:

http://lists.uclibc.org/pipermail/uclibc/2009-January/041701.html

Maybe we should just disable it in the 0.9.30 defconfig? What is the
impact of doing that?

[QuickX]

I was able to narrow down the problem a bit more.  It seems that the 
"UCLIBC_SUPPORT_AI_ADDRCONFIG" is what causes the Segfaults/Core Dumps, 
however, this option is only available if UCLIBC_USE_NETLINK is set.

Results: 0.9.30 (with 0.9.30 config, minus UCLIBC_SUPPORT_AI_ADDRCONFIG) 
works fine for dropbear and samba.


> What is the impact of doing that?
I'm not really sure of the impact.  From the uClibc-menuconfig help it 
states following if they are helpful.

UCLIBC_USE_NETLINK:
  ?
  ? In newer versions of Linux (2.4.17+), support was added for querying
  ? network device information via netlink rather than the old style
  ? ioctl's.  Most of the time, the older ioctl style is sufficient (and
  ? it is smaller than netlink), but if you find that not all of your
  ? devices are being returned by the if_nameindex() function, you will
  ? have to use the netlink implementation.
  ?
  ? Most people can safely answer N.

UCLIBC_SUPPORT_AI_ADDRCONFIG:
  ?
  ? The implementation of AI_ADDRCONFIG is aligned with the glibc
  ? implementation using netlink to query interfaces to find both
  ? ipv4 and ipv6 support. This is only needed if an application uses
  ? the AI_ADDRCONFIG flag.
  ?
  ? Most people can safely answer N.

Ok, thanks, I'll disable it in the defconfig.
