found 740509 glibc/2.19-11 tags 740509 + patch thanks Hi, I'm sorry, I made a mistake testing this on kfreebsd-i386; I'd modified a header in the build tree and forgotten about it. As a result, the workaround was not effective on kfreebsd-i386 10.1. Some additional code is committed now to svn/glibc-bsd/trunk/glibc-ports as r5668. Please could you pull in that change in the next glibc upload. I've re-tested it on kfreebsd-i386, kfreebsd-amd64, for kernels 9.0 and 10.1.

It works! It passed glibc's testsuite when running on kfreebsd-i386 9.0
(like on the buildds), and has fixed ifconfig on kfreebsd-i386 10.1.
I've also committed it to /svn/glibc-bsd/trunk/glibc-ports
Please could we get this into the next glibc upload, in order to fix
kfreebsd-i386 networking?
It might be an idea to also bump the Build-Depends to
kfreebsd-kernel-headers ( 10.1~) [kfreebsd-any]
because otherwise, building against older k-k-h could produce a glibc
that still has this bug when run on a 10.1 (sid/jessie) kernel.
Thanks!

Bug#740509: ifconfig: ioctl(SIOCGIFINFO_IN6): No such device or address
Hi!
The attached patch is my best guess at how to fix this bug. I'm still
testing it myself, but I'm sharing it now in case anyone else is able to
build glibc on kfreebsd-i386 and also help test. (It can take many
hours to build glibc).
getifaddrs() uses a NET_RT_IFLIST sysctl to get back a struct rt_msghdr
followed by a struct sockaddr_dl. From kfreebsd 9.0 - 10.1, the
rt_msghdr seems to be 4 bytes larger on kfreebsd-i386 only (not on
kfreebsd-amd64, probably because there was some padding for alignment).
With the current build of glibc (based on outdated
kfreebsd-kernel-headers), ifconfig fails to get a list of interface
names on 10.1 kernels, but can still do that within a chroot on 9.0.
If glibc is rebuilt against latest kfreebsd-kernel-headers ( 10.1~), I
think it works on 10.1 kernels, but stops working on kfreebsd-i386 9.0.
The buildds run kfreebsd 9.0, so I expect it would FTBFS when that
happens. The attached patch uses rt_msghdr-ifm_msglen to guess the
running kernel version and accordingly, find the right place for the
struct sockaddr_dl. I expect it will still work for the i386-on-amd64
compat case also.

Have tried on upstream 32-bit kernel with 32-bit userland, and it
doesn't have this issue. So it is probably a bug in the compat code
only.
GNU libc should perhaps start with an initial 1024-byte allocation
anyway, since 512 bytes is no longer enough even for a machine with
only one NIC.

Bug#740509: ifconfig: ioctl(SIOCGIFINFO_IN6): No such device or address
Actually that workaround referred to *if_msghdr* but recent changes have been to *ifa_msghdr*: https://alioth.debian.org/scm/viewvc.php/trunk/glibc-ports/kfreebsd/if_index.c?root=glibc-bsdr1=1716r2=2484 so the problem is not quite what I thought. I think I've been seeing two bugs at once. This history of this is: struct if_msghdr contains a (pointer to a) struct if_data (since forever) which will be either a 32- or 64-bit sized member depending on the architecture. ABI would thus be incompatible between a 32-bit userland and 64-bit kernel. Building glibc in a kfreebsd-i386 sid chroot, on a kfreebsd-amd64 9.0 kernel, fails test_ifindex due to the above issue. Building glibc in a kfreebsd-i386 sid chroot, on a kfreebsd-i386 9.0 kernel like the Debian buildds have, is fine. But then userland tools like ifconfig don't work properly on any 10.x kernel. Building glibc in a kfreebsd-amd64 sid chroot, on kfreebsd-amd64 9.0 or 10.0 kernels is fine, and userland tools work fine on whichever kernel. Making this particularly awkward, however we fix this for kfreebsd-i386, it probably still needs to work on a 9.0 (wheezy) kernel because the buildds must run that until jessie is released.

Bug#740509: ifconfig: ioctl(SIOCGIFINFO_IN6): No such device or address
I think I've found a *different* bug while looking for this.
A sysctl { CTL_NET, PF_ROUTE, 0, 0, NET_RT_IFLIST, 0 } from
kfreebsd-i386 userland on kfreebsd-amd64 9.0 or 10.0 kernel, never
seems to fail with ENOMEM! Regardless of given buffer size:
Calling sysctl with buffer of size 1024
sysctl() returned 672 bytes
Got message of length 152
Got message of length 152
Got message of length 152
Got message of length 152
Got message of length 64
which correctly describes four network interfaces (followed by a
shorter NEWADDR message).
It goes wrong when the buffer is too small:
Calling sysctl with buffer of size 512
sysctl() returned 512 bytes
Got message of length 152
Got message of length 152
Got message of length 152
Message of length 152 overflows the buffer!
Calling sysctl with buffer of size 128
sysctl() returned 128 bytes
Message of length 152 overflows the buffer!
The same compiled on kfreebsd-amd64 userland however, also with
four network interfaces:
Calling sysctl with buffer of size 512
sysctl() failed with errno 12
which is correct behaviour.
GNU libc uses an initial buffer size of 512, re-trying with the buffer
doubling in size in case of ENOMEM. My own test case is attached.
(Note that the sysctl shrinks bufsize to a smaller value if the
response fits in the buffer; leaves it unchanged otherwise).
