* [libc] Add strtoull()Piotr Jaroszyński2010-08-191-0/+40
| | | | | | | | | | Don't implement strtoul() on top of strtoull() as strtoull() is much bigger and only used on linux currently. Instead refactor most of the logic out of strtoul() into static inlines and reuse that. Also put it in a separate object so it won't get linked in.

* [tcp] Allow out-of-order receive queue to be discardedMichael Brown2010-07-211-0/+12
| | | | | | | | | Allow packets in the receive queue to be discarded in order to free up memory. This avoids a potential deadlock condition in which the missing packet can never be received because the receive queue is occupying all of the memory available for further RX buffers.

* [tcp] Handle out-of-order received packetsMichael Brown2010-07-211-1/+30
| | | | | | | | | | | | | | | Maintain a queue of received packets, so that lost packets need not result in retransmission of the entire TCP window. Increase the TCP window to 8kB, in order that we can potentially transmit enough duplicate ACKs to trigger Fast Retransmission at the sender. Using a 10MB HTTP download in qemu-kvm with an artificial drop rate of 1 in 64 packets, this reduces the download time from around 26s to around 4s. Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [virtio] Replace virtio-net with native iPXE driverStefan Hajnoczi2010-07-173-4/+9
| | | | | | | | | | | | | | | | | | | | | | This patch adds a native iPXE virtio-net driver and removes the legacy Etherboot virtio-net driver. The main reasons for doing this are: 1. Multiple virtio-net NICs are now supported by iPXE. The legacy driver kept global state and caused issues in virtual machines with more than one virtio-net device. 2. Faster downloads. The native iPXE driver downloads 100 MB over HTTP in 12s, the legacy Etherboot driver in 37s. This simple benchmark uses KVM with tap networking and the Python SimpleHTTPServer both running on the same host. Changes to core virtio code reduce vring descriptors to 256 (QEMU uses 128 for virtio-blk and 256 for virtio-net) and change the opaque token from u16 to void*. Lowering the descriptor count reduces memory consumption. The void* opaque token change makes driver code simpler.

* [build] Mark weak functions noinlineStefan Hajnoczi2010-07-141-2/+9
| | | | | | | | | | | | | | | | | | | | | Weak functions whose visibility is hidden may be inlined due to a bug in GCC. Explicitly mark weak functions noinline to work around the problem. This makes the PXE_MENU config option work again, the PXE boot menu was never being called because the compiler inlined a weak stub function. The GCC bug was identified and fixed by Richard Sandiford <rdsandiford@googlemail.com> but in the meantime iPXE needs to implement a workaround.

* [interface] Allow for non-pass-through interface methodsMichael Brown2010-06-221-0/+15
| | | | | | | | | | | | | | | | | | | | | | | xfer_vredirect() should not be allowed to propagate to a pass-through interface. For example, when an HTTPS connection is opened, the redirect message should cause the TLS layer to reopen the TCP socket, rather than causing the HTTP layer to disconnect from the TLS layer. Fix by allowing for non-pass-through interface methods, and setting xfer_vredirect() to be one such method. This is slightly ugly, in that it complicates the notion of an interface method call by adding a "pass-through" / "non-pass-through" piece of metadata. However, the only current user of xfer_vredirect() is iscsi.c, which uses it only because we don't yet have an ioctl()-style call for retrieving the underlying socket address. The new interface infrastructure allows for such a call to be created, at which time this sole user of xfer_vredirect() can be removed, xfer_vredirect() can cease to be an interface method and become simply a wrapper around xfer_vreopen(), and the concept of a non-pass-through interface method can be reverted.

* [interface] Convert all data-xfer interfaces to generic interfacesMichael Brown2010-06-229-317/+60Star
| | | | | | | | | | | | | | Remove data-xfer as an interface type, and replace data-xfer interfaces with generic interfaces supporting the data-xfer methods. Filter interfaces (as used by the TLS layer) are handled using the generic pass-through interface capability. A side-effect of this is that deliver_raw() no longer exists as a data-xfer method. (In practice this doesn't lose any efficiency, since there are no instances within the current codebase where xfer_deliver_raw() is used to pass data to an interface supporting the deliver_raw() method.)

* [interface] Convert all job-control interfaces to generic interfacesMichael Brown2010-06-224-141/+11Star
| | | | | | | | | Remove job-control as an interface type, and replace job-control interfaces with generic interfaces supporting the close() method. (Both done() and kill() are absorbed into the function of close(); kill() is merely close(-ECANCELED).) Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [interface] Expand object interface to allow for polymorphic interfacesMichael Brown2010-06-224-30/+191
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We have several types of object interface at present (data-xfer, job control, name resolution), and there is some duplication of functionality between them. For example, job_done(), job_kill() and xfer_close() are almost isomorphic to each other. This updated version of the object interface mechanism allows for each interface to export an arbitrary list of supported operations. Advantages include: Operations methods now receive a pointer to the object, rather than a pointer to the interface. This allows an object to, for example, implement a single close() method that can handle close() operations from any of its exposed interfaces. The close() operation is implemented as a generic operation (rather than having specific variants for data-xfer, job control, etc.). This will allow functions such as monojob_wait() to be used to wait for e.g. a name resolution to complete. The amount of boilerplate code required in objects is reduced, not least because it is no longer necessary to include per-interface methods that simply use container_of() to derive a pointer to the object and then tail-call to a common per-object method. The cost of adding new operations is reduced; adding a new data-xfer operation such as stat() no longer incurs the penalty of adding a .stat member to the operations table of all existing data-xfer interfaces. The data-xfer, job control and name resolution interfaces have not yet been updated to use the new interface mechanism, but the code will still compile and run.
