* Back out rev.1.91 which implemented bulk read transfers in ugen(4) asBrian Feldman2004-10-131-151/+31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | asynchronous. I realize that this means the custom application will not work as written, but it is not okay to break most users of ugen(4). The major problem is that a bulk read transfer is not an interrupt saying that X bytes are available -- it is a request to be able to receive up to X bytes, with T timeout, and S short-transfer-okayness. The timeout is a software mechanism that ugen(4) provides and cannot be implemented using asynchronous reads -- the timeout must start at the time a read is done. The status of up to how many bytes can be received in this transfer and whether a short transfer returns data or error is also encoded at least in ohci(4)'s requests to the controller. Trying to detect the "maximum width" results in using a single buffer of far too small when an application requests a large read. Even if you combat this by replacing all buffers again with the maximal sized read buffer (1kb) that ugen(4) would allow you to use before, you don't get the right semantics -- you have to throw data away or make all the timeouts invalid or make the short-transfer settings invalid. There is no way to do this right without extending the ugen(4) API much further -- it breaks the USB camera interfaces used because they need a chain of many maximal-width transfers, for example, and it makes cross-platform support for all the BSDs gratuitously hard. Instead of trying to do select(2) on a bulk read pipe -- which has neither the information on desired transfer length nor ability to implement timeout -- an application can simply use a kernel thread and pipe to turn that endpoint into something poll-able. It is unfortunate that bulk endpoints cannot provide the same semantics that interrupt and isochronous endpoints can, but it is possible to just use ioctl(USB_GET_ENDPOINT_DESC) to find out when different semantics must be used without preventing the normal users of the ugen(4) device from working.

* Refine the turnstile and sleep queue interfaces just a bit:John Baldwin2004-10-127-77/+117
| | | | | | | | | | | | | | | | | | | | | | | | | | | | - Add a new _lock() call to each API that locks the associated chain lock for a lock_object pointer or wait channel. The _lookup() functions now require that the chain lock be locked via _lock() when they are called. - Change sleepq_add(), turnstile_wait() and turnstile_claim() to lookup the associated queue structure internally via _lookup() rather than accepting a pointer from the caller. For turnstiles, this means that the actual lookup of the turnstile in the hash table is only done when the thread actually blocks rather than being done on each loop iteration in _mtx_lock_sleep(). For sleep queues, this means that sleepq_lookup() is no longer used outside of the sleep queue code except to implement an assertion in cv_destroy(). - Change sleepq_broadcast() and sleepq_signal() to require that the chain lock is already required. For condition variables, this lets the cv_broadcast() and cv_signal() functions lock the sleep queue chain lock while testing the waiters count. This means that the waiters count internal to condition variables is no longer protected by the interlock mutex and cv_broadcast() and cv_signal() now no longer require that the interlock be held when they are called. This lets consumers of condition variables drop the lock before waking other threads which can result in fewer context switches. MFC after: 1 month Notes: svn path=/head/; revision=136445

* When the access control on creating raw sockets was modified so thatRobert Watson2004-10-121-20/+41
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | processes in jail could create raw sockets, additional access control checks were added to raw IP sockets to limit the ways in which those sockets could be used. Specifically, only the socket option IP_HDRINCL was permitted in rip_ctloutput(). Other socket options were protected by a call to suser(). This change was required to prevent processes in a Jail from modifying system properties such as multicast routing and firewall rule sets. However, it also introduced a regression: processes that create a raw socket with root privilege, but then downgraded credential (i.e., a daemon giving up root, or a setuid process switching back to the real uid) could no longer issue other unprivileged generic IP socket option operations, such as IP_TOS, IP_TTL, and the multicast group membership options, which prevented multicast routing daemons (and some other tools) from operating correctly. This change pushes the access control decision down to the granularity of individual socket options, rather than all socket options, on raw IP sockets. When rip_ctloutput() doesn't implement an option, it will now pass the request directly to in_control() without an access control check. This should restore the functionality of the generic IP socket options for raw sockets in the above-described scenarios, which may be confirmed with the ipsockopt regression test. RELENG_5 candidate.
