From 5d6111790e1cd07d1156f47bca0733f6d715337f Mon Sep 17 00:00:00 2001 From: Michael Chang <mchang@suse.com> Date: Wed, 22 Feb 2017 14:27:50 +0800 Subject: [PATCH] Support UEFI networking protocols References: fate#320130, bsc#1015589, bsc#1076132 Patch-Mainline: no V1: * Add preliminary support of UEFI networking protocols * Support UEFI HTTPS Boot V2: * Workaround http data access in firmware * Fix DNS device path parsing for efinet device * Relaxed UEFI Protocol requirement * Support Intel OPA (Omni-Path Architecture) PXE Boot V3: * Fix bufio in calculating address of next_buf * Check HTTP respond code * Use HEAD request method to test before GET * Finish HTTP transaction in one go * Fix bsc#1076132 V4: * Add fs_ prefix with upstream commit ad4bfeec5 Change fs functions to add fs_ prefix V5: * Use overflow checking primitives where the arithmetic expression for buffer allocations may include unvalidated data * Use grub_calloc for overflow check and return NULL when it would occur. --- grub-core/Makefile.core.def | 18 + grub-core/io/bufio.c | 2 +- grub-core/kern/efi/efi.c | 96 ++- grub-core/net/drivers/efi/efinet.c | 27 + grub-core/net/efi/dhcp.c | 397 ++++++++++ grub-core/net/efi/efi_netfs.c | 57 ++ grub-core/net/efi/http.c | 419 +++++++++++ grub-core/net/efi/ip4_config.c | 398 ++++++++++ grub-core/net/efi/ip6_config.c | 422 +++++++++++ grub-core/net/efi/net.c | 1428 ++++++++++++++++++++++++++++++++++++ grub-core/net/efi/pxe.c | 424 +++++++++++ grub-core/net/net.c | 74 ++ include/grub/efi/api.h | 181 ++++- include/grub/efi/dhcp.h | 343 +++++++++ include/grub/efi/http.h | 215 ++++++ include/grub/net/efi.h | 144 ++++ util/grub-mknetdir.c | 23 +- 17 files changed, 4627 insertions(+), 41 deletions(-) create mode 100644 grub-core/net/efi/dhcp.c create mode 100644 grub-core/net/efi/efi_netfs.c create mode 100644 grub-core/net/efi/http.c create mode 100644 grub-core/net/efi/ip4_config.c create mode 100644 grub-core/net/efi/ip6_config.c create mode 100644 grub-core/net/efi/net.c create mode 100644 grub-core/net/efi/pxe.c create mode 100644 include/grub/efi/dhcp.h create mode 100644 include/grub/efi/http.h create mode 100644 include/grub/net/efi.h Index: grub-2.04/grub-core/Makefile.core.def =================================================================== --- grub-2.04.orig/grub-core/Makefile.core.def +++ grub-2.04/grub-core/Makefile.core.def @@ -1854,7 +1854,6 @@ module = { module = { name = linuxefi;
