2022-02-17bootp: fix g_str_has_prefix warning/criticalMarc-André Lureau1-1/+1
Fixes: commit 60535013c3e ("bootp: add support for UEFI HTTP boot") Signed-off-by: Marc-André Lureau <marcandre.lureau@redhat.com>
2022-01-25bootp: add support for UEFI HTTP bootIgnat Korchagin1-0/+23
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.

2021-06-21dhcp: Always send DHCP_OPT_LEN bytes in optionsSamuel Thibault1-3/+3
RFC2131 suggests that the options field may be at least 312 bytes. Some DHCP clients seem to assume that it has to be at least 312 bytes.

2021-06-14bootp: limit vendor-specific area to input packet memory bufferMarc-André Lureau1-11/+15
sizeof(bootp_t) currently holds DHCP_OPT_LEN. Remove this optional field from the structure, to help with the following patch checking for minimal header size. Modify the bootp_reply() function to take the buffer boundaries and avoiding potential buffer overflow.
