* When user_frac in the polling subsystem is low it is going to busy theAttilio Rao2009-05-3020-136/+246
| | | | | | | | | | | | | | | | | | | | | | | | CPU for too long period than necessary. Additively, interfaces are kept polled (in the tick) even if no more packets are available. In order to avoid such situations a new generic mechanism can be implemented in proactive way, keeping track of the time spent on any packet and fragmenting the time for any tick, stopping the processing as soon as possible. In order to implement such mechanism, the polling handler needs to change, returning the number of packets processed. While the intended logic is not part of this patch, the polling KPI is broken by this commit, adding an int return value and the new flag IFCAP_POLLING_NOCOUNT (which will signal that the return value is meaningless for the installed handler and checking should be skipped). Bump __FreeBSD_version in order to signal such situation. Reviewed by: emaste Sponsored by: Sandvine Incorporated Notes: svn path=/head/; revision=193096

* Place hostnames and similar information fully under the prison system.Jamie Gritton2009-05-292-6/+9
| | | | | | | | | | | | | | | | | | | | The system hostname is now stored in prison0, and the global variable "hostname" has been removed, as has the hostname_mtx mutex. Jails may have their own host information, or they may inherit it from the parent/system. The proper way to read the hostname is via getcredhostname(), which will copy either the hostname associated with the passed cred, or the system hostname if you pass NULL. The system hostname can still be accessed directly (and without locking) at prison0.pr_host, but that should be avoided where possible. The "similar information" referred to is domainname, hostid, and hostuuid, which have also become prison parameters and had their associated global variables removed.

* Last minute TTY API change: remove mutex argument from tty_alloc().Ed Schouten2009-05-2911-12/+12
| | | | | | | | | | | | | I don't want people to override the mutex when allocating a TTY. It has to be there, to keep drivers like syscons happy. So I'm creating a tty_alloc_mutex() which can be used in those cases. tty_alloc_mutex() should eventually be removed. The advantage of this approach, is that we can just remove a function, without breaking the regular API in the future. Notes: svn path=/head/; revision=193018

* Ensure that there are enough TX mbuf ring slots available before beginningAdrian Chadd2009-05-271-1/+44
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | to dequeue a packet. The tx path was trying to ensure that enough Xenbus TX ring slots existed but it didn't check to see whether the mbuf TX ring slots were also available. They get freed in xn_txeof() which occurs after transmission, rather than earlier on in the process. (The same happens under Linux too.) Due to whatever reason (CPU use, scheduling, memory constraints, whatever) the mbuf TX ring may not have enough slots free and would allocate slot 0. This is used as the freelist head pointer to represent "free" mbuf TX ring slots; setting this to an actual mbuf value rather than an id crashes the code. This commit introduces some basic code to track the TX mbuf ring use and then (hopefully!) ensures that enough slots are free in said TX mbuf ring before it enters the actual work loop. A few notes: * Similar logic needs to be introduced to check there are enough actual slots available in the xenbuf TX ring. There's some logic which is invoked earlier but it doesn't hard-check against the number of available ring slots. Its trivial to do; I'll do it in a subsequent commit. * As I've now commented in the source, it is likely possible to deadlock the driver under certain conditions where the rings aren't receiving any changes (which I should enumerate) and thus Xen doesn't send any further software interrupts. I need to make sure that the timer(s) are running right and the queues are periodically kicked. PR: 134926 Notes: svn path=/head/; revision=192871

| | | | | | | | | | | code. Slot 0 must always remain "free" and be a pointer to the first free entry in the mbuf descriptor list. It is thus an error to have code allocate or push slot 0 back into the list. Notes: svn path=/head/; revision=192868

| | | | | | | | | | | | | | | | | get a quick snapshot of the kernel's symbol table including the symbols from any loaded modules (the symbols are all merged into one symbol table). Unlike like other implementations, this ksyms driver maps memory in the process memory space to store the snapshot at the time /dev/ksyms is opened. It also checks to see if the process has already a snapshot open and won't allow it to open /dev/ksyms it again until it closes first. This prevents kernel and process memory from being exhausted. Note that /dev/ksyms is used by the lockstat(1) command. Reviewed by: gallatin kib (freebsd-arch) Approved by: gnn (mentor) Notes: svn path=/head/; revision=192859

| | | | | | | | | | | | | | | | | | | | severe silicon bugs that can't handle VLAN hardware tagging as well as status LE writeback bug. The status LE writeback bug is so critical we can't trust status word of received frame. To accept frames on Yukon FE+ A0 msk(4) just do minimal check for received frames and pass them to upper stack. This means msk(4) can pass corrupted frames to upper layer. You have been warned! Also I supposed RX_GMF_FL_THR to be 32bits register but Linux driver treated it as 16bit register so follow their leads. At least this does not seem to break msk(4) on Yukon FE+.
