libnl-3.2.8 has significant API changes from 3.2.7. Just take a look at this gem, for instance: http://git.infradead.org/users/tgr/libnl.git/commitdiff/e0482794a8b70ae23361bfbe3701d4c2c96c66a6?hp=adbc5687358ef62c5edb349332b3d031c01fcbb2 In other words, with 3.2.8, all libnl users that checked for a non-zero return value from nl_recvmsgs() (which e.g. networkmanager does in its _nl80211_send_and_recv() function) will now start failing. I strongly recommend masking libnl-3.2.8 until the packages in the tree have caught up with the new API.
QA-masked until this is sorted out. This is API _and_ ABI breakage even though it slips under the radar of binary interfaces.
Thank you Albert, I had this problem tonight and I was in the dark. Now I masked manually the package.
(In reply to comment #2) > QA-masked You've just made that up, didn't you?
Version 3.2.9 has been released on May 8, 2012. Note: The 3.2.9 release fixes a regression in nl_recvmsgs(). The change in semantics regarding the return value has broken nl_wait_for_ack() among other things. Behaviour has been restored. Please do not distribute 3.2.8.
Changelog for 3.2.8 -> 3.2.9 Jeroen Roovers (1): Fix two bugs in 3.2.8/doc/ Thomas Graf (2): nl: Fix return value of nl_recvmsgs() 3.2.9 release
