Linux-Kernel ArchiveRenfsd deadlock, 2.6.36-rc3.

blocking would lead to deadlock or we need a state change to occur before retrying the operation that would have deadlocked. If we don't put a backoff in, then we simply burn CPU until the condition clears. In the case of the data Io completion workqueue processing, the CPU burn occurred when the only item on the workqueue was the inode that. > blocking would lead to deadlock or we need a state change to occur > before retrying the operation that would have deadlocked.

The wait_for_unix_gc function in net/unix/garbage.c in the Linux kernel before 2.6.37-rc3-next-20101125 does not properly select times for garbage collection of inflight sockets, which allows local users to cause a denial of service system hang via crafted use of the socketpair and sendmsg system calls for SOCK_SEQPACKET sockets. 4. The 2.6.36-rc3 kernel prepatch is out. "Nothing in particular stands out that I can recall. As usual, it's mostly driver updates 65%, of which a large piece by line count is just the removal of a staging driver that isn't really ready nor making any progress. Hi, I would like to discuss here a problem we are having in the Bluetooth Layer. There we have the Enhanced Retransmission ModeERTM which is a reliable mode.

Linux 2.6.36 released 20 October, 2010. Summary: Linux 2.6.36 includes support for the Tilera architecture, a new filesystem notification interface called fanotify, a redesign of workqueues optimized for concurrency, CIFS local caching, support for Intel Intelligent Power Sharing in i3/5 systems, integration of the kernel debugger and KMS. You all know the drill by now: another week, another -rc. Nothing in particular stands out that I can recall. As usual, it's mostly driver updates 65%, of which a large piece by line count is.
