On 2010-04-14, Kostik Belousov wrote: First, I think we shall sort dirent-dd_dlist so that symlinks are located before any other entries, and allow for duplication of any name with the name of symlink. What will happen when user deletes a symlink covering a device? Uncovering the device may a bit surprising? If user created directories will be allowed one day, they will face the same problem. I remember there was a PR to change devfs_symlink() so that symlink is added to dd_dlist into head, not to a tail, as it is done now. kern/114057 Assume that all full devfs pathes except symlinks are stored somewhere with type information for the component at the end. Then, just iterating this set at make_dev() time, we can verify that name is not a duplicate, and that the path components are not already used as device name (only as directories). The pathes storage need to be protected by dev_mtx. Possibly, the cdev_priv.c_dev.__si_namebuf may be reused at the cost of long check at the make_dev() time. Could you elaborate on this? I am not sure if I understand what you mean with __si_namebuf reuse. What do you think of this ? I don't see anything obviously wrong with it. -- Jaakko ___ svn-src-head@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/svn-src-head To unsubscribe, send any mail to svn-src-head-unsubscr...@freebsd.org

Is it possible to do it easily at all (the user and GEOM are seemingly very far from each other)? I can easily[*] modify the I/O priority/weight of process or threads, but you have to keep in mind that once a request is intercepted by the filesystem code (e.g. for delayed writes, or avoid duplication of pending reads), by the time it hits the disk it is not trivial to tell who should be charged for it. This is an area where we still need to experiment a bit (especially to find on which process issues which request, say for metadata, delayed writes, shared reads). [*] the 'easy' way is put the information in an external hash table and look it up using as a search key either of uid, gid, pid/struct thread *. I think we did something like this in the GSOC2005 project on disk scheduling. A more intrusive way involves extending the struct thread with an extra field to store the io priority. cheers luigi ___ svn-src-head@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/svn-src-head To unsubscribe, send any mail to svn-src-head-unsubscr...@freebsd.org

Also include an example anticipatory scheduler, gsched_rr, which gives very nice performance improvements in presence of competing random access patterns. This is joint work with Fabio Checconi, developed last year and presented at BSDCan 2009. You can find details in the README file or at Are there any plans to bring in something like Linux's ionice (or even better solutions)? Is it possible to do it easily at all (the user and GEOM are seemingly very far from each other)? I can easily[*] modify the I/O priority/weight of process or threads, but you have to keep in mind that once a request is intercepted by the filesystem code (e.g. for delayed writes, or avoid duplication of pending reads), by the time it hits the disk it is not trivial to tell who should be charged for it. This is an area where we still need to experiment a bit (especially to find on which process issues which request, say for metadata, delayed writes, shared reads). [*] the 'easy' way is put the information in an external hash table and look it up using as a search key either of uid, gid, pid/struct thread *. I think we did something like this in the GSOC2005 project on disk scheduling. A more intrusive way involves extending the struct thread with an extra field to store the io priority. What would already be helpful, is an I/O time measurement of the overall system and have that displayed in, eg., vmstat like Linux and Solaris do. It gives a better measure of if a system is CPU bound or I/O bound or neither. Can the scheduler help here?

Re: svn commit: r206452 - head/sys/netinet
On 04/10/10 13:05, Bruce M Simpson wrote: Log: Fix a few issues related to the legacy 4.4 BSD multicast APIs. IPv4 addresses can and do change during normal operation. Testing by pfSense developers exposed an issue where OpenOSPFD was using the IPv4 address to leave the OSPF link-scope multicast groups on a dynamic OpenVPN tun interface, rather than using RFC 3678 with the interface index, which won't be raced when the interface's addresses change. I should point out that IP multicast is counter-intuitive in many areas. It seems that knowledge of how to work with it effectively is not that widespread. People who have a need to use it, often have very specific requirements. IP multicast group membership is always scoped to physical links [1]. The 4.4BSD API originally used the primary IP address to identify each link. Unfortunately this is not a persistent identifier, especially so in the use-case which had problems. In the updated API specified in RFC 3678, the primary key for multicast memberships, changes to the interface index. routed(8) in FreeBSD's SVN tree uses this new API; thanks to phk for reviewing and testing my change. In the case of OpenOSPFD+OpenVPN, the issue manifested itself in situations where this primary IP address changed. OpenVPN shims address assignment as part of its wire protocol, which is where the address change originates. This is purely a by-product of using an API which depends on using an IPv4 address as a key (IP_ADD_MEMBERSHIP/IP_DROP_MEMBERSHIP), when that key may change at any time. There's some time domain uncertainty with that change. PF_ROUTE is an out-of-band mechanism used by OpenOSPFD to learn about the address change, and it is dispatched separately from the change itself; there may be queueing and context switches involved. It also creates some ambiguity for in_multi instances, which the kernel may not be able to resolve, if that key has been blown away. Fortunately, such ambiguity is private to each socket. Furthermore, this makes IGMP somewhat unreliable, although mechanisms do exist in the protocol to work-around the end-station's identifier being lost in this way. The upstream IGMP querier (usually the mcast router) will hold state based on the end-station's primary IP address, this will eventually time out due to unanswered queries. MLD side-steps this by always requiring an IPv6 link-scope address in control traffic. Using the more recent multicast RFCs, supported now by Windows, Linux, OpenSolaris, and now FreeBSD, can side-step these issues; it is the preferred API. P.S. HEAD was probably already resilient against this for joins. I plan to MFC a similar version of this change to 8 soon. [1] sendto() to an IP multicast address, without an interface specified, makes no sense -- unless the host is also an mcast forwarder. You can get away with default route resolution through the routing tables up to a point, but if your box is multihomed, all bets are off. ___ svn-src-head@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/svn-src-head To unsubscribe, send any mail to svn-src-head-unsubscr...@freebsd.org
