ncsi: Add basic Get Version ID response See merge request slirp/libslirp!122
2022-05-11ncsi: Add Get Version ID commandPeter Delevoryas1-1/+12
Get Version ID is one of the first commands used in NC-SI, because BMC's use a lot of OEM NC-SI extensions, and you need to query the device's manufacturer through Get Version ID before you can decide which OEM NC-SI extensions to use. The response format is documented in the NC-SI spec[1]. We're just setting the NC-SI version supported to 1.0.0 (BCD-encoded[2]) and returning the manufacturer's ID in network byte-order.

2022-05-11slirp: Add manufacturer's IDPeter Delevoryas3-1/+13
The manufacturer's ID is used in NC-SI commands such as "Get Version ID" [1]. It is also essential to providing a path towards adding OEM (non-standardized) NC-SI commands. This field should be derived from the IANA Private Enterprise Numbers list, per the NC-SI specification. It may be useful for things besides NC-SI, but NC-SI responses for BMC's in QEMU are the main use case I have in mind. Note: I did not add this attribute to slirp_init, since it is deprecated.

2022-04-11slirp: invoke client callback before creating timersPaolo Bonzini6-6/+12
The introduction of .timer_new_opaque adds an interesting conundrum. The Slirp* needs to be stored in .timer_new_opaque so that it can be passed back to slirp_handle_timer, but it is not returned by slirp_new and slirp_init until after the first call to .timer_new_opaque (which is in ip6_init). This is a problem for programs that, like QEMU, use more than one Slirp*. Fix them by passing the Slirp* to a callback before slirp_new returns, and initializing the timer afterwards.

2022-04-10introduce timer_new_opaque callbackPaolo Bonzini4-1/+38
Add a new callback that supports CFI better by avoiding having function pointers in the external libslirp API. Instead, the new API passes an opaque integer and requests the application to call a new libslirp function when the timer expires. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2022-04-10introduce slirp_timer_new wrapperPaolo Bonzini5-6/+30
In order to support CFI, we would like to avoid passing function pointers out of libslirp, and instead use opaque integers for the timer callbacks. This patch introduces an internal API for creating a timer that is based on such a timer callback. For now, it receives the id (SLIRP_TIMER_RA is the only one) and calls slirp->cb->timer_new. The prototype of ra_timer_handler is changed slightly to fit better with the next patch which introduces a new libslirp function, to be called on timer expiration.

2022-02-11slirp: Don't duplicate packet in tcp_reassBrett Nash1-3/+0
When debug is enabled, we duplicate the packet in tcp_reass, but ti is still pointing to the old buffer, resulting in a use after free. This makes valgrind debugging a little trickier, but makes it crash a lot less. Signed-off-by: Brett Nash <nash@fb.com>

2022-02-10mbuf: Use SLIRP_DEBUG to enable mbuf debugging instead of DEBUG Brett Nash2-2/+2
DEBUG is set by a number of IDEs and development environments (*cough* xcode *cough*). This means we use mbuf duplication when we don't need (or expect) it. Change the name to SLIRP_DEBUG to enable this feature. Signed-off-by: Pablo Fiori <pablofiori@fb.com> Signed-off-by: Brett Nash <nash@fb.com>

Add VMS_END marker See merge request slirp/libslirp!112
2022-02-02Add VMS_END markerDr. David Alan Gilbert1-0/+4
The migration VMSTATE_END_OF_LIST marker relies on a NULL field to mark th eend of a list; that's a bit delicate when the marker is forgotten and the code hits a NULL by luck. Use an explicit flag to mark the end as well. See: https://lists.gnu.org/archive/html/qemu-devel/2022-01/msg03025.html Signed-off-by: Dr. David Alan Gilbert <dgilbert@redhat.com>

bootp: add support for UEFI HTTP boot See merge request slirp/libslirp!111
2022-01-25bootp: add support for UEFI HTTP bootIgnat Korchagin2-0/+24
Current bootp implementation is only one step away from supporting UEFI HTTP boot in QEMU. The only missing bit is that the UEFI specification [1] requires a vendor class identifier option (num 60) set to "HTTPClient" string present in the DHCP response. OVMF [2] indeed ignores the DHCP response and considers UEFI HTTP boot as failed, if this option is not present. With this change one would be able to configure QEMU user networking like below: $ qemu ... -nic user,tftp=tftp-root,bootfile=http://10.0.2.2/ipxe.efi and boot the VM using UEFI HTTP boot instead of TFTP.
