According to the information on the Fedora bug -tracker, only the information from byte 0x1f1 is necessary, so start -copying from there instead. - -Author: Luca Boccassi -Bug-Fedora: https://bugzilla.redhat.com/show_bug.cgi?id=1418360 -Forwarded: no - -Patch-Name: fix-lockdown.patch ---- - grub-core/loader/i386/efi/linux.c | 5 ++++- - 1 file changed, 4 insertions(+), 1 deletion(-) - -diff --git a/grub-core/loader/i386/efi/linux.c b/grub-core/loader/i386/efi/linux.c -index 16372a0c8..34605dfed 100644 ---- a/grub-core/loader/i386/efi/linux.c -+++ b/grub-core/loader/i386/efi/linux.c -@@ -28,6 +28,7 @@ - #include - #include - #include -+#include - - GRUB_MOD_LICENSE ("GPLv3+"); - -@@ -334,7 +335,9 @@ grub_cmd_linux (grub_command_t cmd __attribute__ ((unused)), - lh.code32_start = (grub_uint32_t)(grub_addr_t) kernel_mem; - } - -- grub_memcpy (params, &lh, 2 * 512); -+ /* do not overwrite below boot_params->hdr to avoid setting the sentinel byte */ -+ start = offsetof (struct linux_kernel_params, setup_sects); -+ grub_memcpy ((grub_uint8_t *)params + start, (grub_uint8_t *)&lh + start, 2 * 512 - start); - - params->type_of_loader = 0x21; - diff --git a/debian/patches/gfxpayload-dynamic.patch b/debian/patches/gfxpayload-dynamic.patch index fc222d2ce..86ebdf9dd 100644 --- a/debian/patches/gfxpayload-dynamic.patch +++ b/debian/patches/gfxpayload-dynamic.patch @@ -1,4 +1,4 @@ -From bff220e7e6189f09678b9a25e9e92fc65b327268 Mon Sep 17 00:00:00 2001 +From b8a1c06ee965e05f536fecbbdcba1762049efd4e Mon Sep 17 00:00:00 2001 From: Evan Broder Date: Mon, 13 Jan 2014 12:13:29 +0000 Subject: Add configure option to enable gfxpayload=keep dynamically @@ -44,7 +44,7 @@ index 7dda5bb32..dbc429ce0 100644 AC_SUBST([FONT_SOURCE]) diff --git a/grub-core/Makefile.core.def b/grub-core/Makefile.core.def -index 67a98abbb..836bf0a59 100644 +index 474a63e68..aadb4cdff 100644 --- a/grub-core/Makefile.core.def +++ b/grub-core/Makefile.core.def @@ -971,6 +971,14 @@ module = { diff --git a/debian/patches/grub-install-pvxen-paths.patch b/debian/patches/grub-install-pvxen-paths.patch index ab6d95b6b..f24f84e90 100644 --- a/debian/patches/grub-install-pvxen-paths.patch +++ b/debian/patches/grub-install-pvxen-paths.patch @@ -1,4 +1,4 @@ -From 8e6b05dbc0a21e8d2a6e8ef2bb831f0bf8ff3a6d Mon Sep 17 00:00:00 2001 +From f4c217049b8d7e1020376b1776d3e59f6bee892c Mon Sep 17 00:00:00 2001 From: Ian Campbell Date: Sat, 6 Sep 2014 12:20:12 +0100 Subject: grub-install: Install PV Xen binaries into the upstream specified diff --git a/debian/patches/grub-install-removable-shim.patch b/debian/patches/grub-install-removable-shim.patch deleted file mode 100644 index eed719a18..000000000 --- a/debian/patches/grub-install-removable-shim.patch +++ /dev/null @@ -1,193 +0,0 @@ -From 3d51b212987d47da2b8c65a911140bbbc2fd3153 Mon Sep 17 00:00:00 2001 -From: Steve McIntyre <93sam@debian.org> -Date: Fri, 14 Jun 2019 16:37:11 +0100 -Subject: Deal with --force-extra-removable with signed shim too - -In this case, we need both the signed shim as /EFI/BOOT/BOOTXXX.EFI -and signed Grub as /EFI/BOOT/grubXXX.efi. - -Also install the BOOTXXX.CSV into /EFI/debian, and FBXXX.EFI into -/EFI/BOOT/ so that it can work when needed (*iff* we're updating the -NVRAM). - -[cjwatson: Refactored also_install_removable somewhat for brevity and so -that we're using consistent case-insensitive logic.] - -Bug-Debian: https://bugs.debian.org/930531 -Last-Update: 2019-06-14 - -Patch-Name: grub-install-removable-shim.patch ---- - util/grub-install.c | 84 ++++++++++++++++++++++++++++++++++++--------- - 1 file changed, 67 insertions(+), 17 deletions(-) - -diff --git a/util/grub-install.c b/util/grub-install.c -index d66de7f8e..35d150c33 100644 ---- a/util/grub-install.c -+++ b/util/grub-install.c -@@ -883,17 +883,13 @@ check_component_exists(const char *dir, - static void - also_install_removable(const char *src, - const char *base_efidir, -- const char *efi_suffix_upper) -+ const char *efi_file, -+ int is_needed) - { -- char *efi_file = NULL; - char *dst = NULL; - char *cur = NULL; - char *found = NULL; - -- if (!efi_suffix_upper) -- grub_util_error ("%s", _("efi_suffix_upper not set")); -- efi_file = xasprintf ("BOOT%s.EFI", efi_suffix_upper); -- - /* We need to install in $base_efidir/EFI/BOOT/$efi_file, but we - * need to cope with case-insensitive stuff here.

Luckily, double serving didn't happen due to +data->block++ during the first iteration. + +Fixes: CID 73624, CID 96690 + +Signed-off-by: Alexey Makhalov +Reviewed-by: Daniel Kiper +--- + grub-core/net/tftp.c | 171 ++++++++++++++----------------------------- + 1 file changed, 53 insertions(+), 118 deletions(-) + +diff --git a/grub-core/net/tftp.c b/grub-core/net/tftp.c +index a0817a075..e6566fa17 100644 +--- a/grub-core/net/tftp.c ++++ b/grub-core/net/tftp.c +@@ -25,7 +25,6 @@ + #include + #include + #include +-#include + #include + + GRUB_MOD_LICENSE ("GPLv3+"); +@@ -106,31 +105,8 @@ typedef struct tftp_data + int have_oack; + struct grub_error_saved save_err; + grub_net_udp_socket_t sock; +- grub_priority_queue_t pq; + } *tftp_data_t; + +-static int +-cmp_block (grub_uint16_t a, grub_uint16_t b) +-{ +- grub_int16_t i = (grub_int16_t) (a - b); +- if (i > 0) +- return +1; +- if (i < 0) +- return -1; +- return 0; +-} +- +-static int +-cmp (const void *a__, const void *b__) +-{ +- struct grub_net_buff *a_ = *(struct grub_net_buff **) a__; +- struct grub_net_buff *b_ = *(struct grub_net_buff **) b__; +- struct tftphdr *a = (struct tftphdr *) a_->data; +- struct tftphdr *b = (struct tftphdr *) b_->data; +- /* We want the first elements to be on top. */ +- return -cmp_block (grub_be_to_cpu16 (a->u.data.block), grub_be_to_cpu16 (b->u.data.block)); +-} +- + static grub_err_t + ack (tftp_data_t data, grub_uint64_t block) + { +@@ -207,73 +183,60 @@ tftp_receive (grub_net_udp_socket_t sock __attribute__ ((unused)), + return GRUB_ERR_NONE; + } + +- err = grub_priority_queue_push (data->pq, &nb); +- if (err) +- return err; +- +- { +- struct grub_net_buff **nb_top_p, *nb_top; +- while (1) +- { +- nb_top_p = grub_priority_queue_top (data->pq); +- if (!nb_top_p) +- return GRUB_ERR_NONE; +- nb_top = *nb_top_p; +- tftph = (struct tftphdr *) nb_top->data; +- if (cmp_block (grub_be_to_cpu16 (tftph->u.data.block), data->block + 1) >= 0) +- break; +- ack (data, grub_be_to_cpu16 (tftph->u.data.block)); +- grub_netbuff_free (nb_top); +- grub_priority_queue_pop (data->pq); +- } +- while (cmp_block (grub_be_to_cpu16 (tftph->u.data.block), data->block + 1) == 0) +- { +- unsigned size; +- +- grub_priority_queue_pop (data->pq); +- +- if (file->device->net->packs.count < 50) ++ /* Ack old/retransmitted block. */ ++ if (grub_be_to_cpu16 (tftph->u.data.block) < data->block + 1) ++ ack (data, grub_be_to_cpu16 (tftph->u.data.block)); ++ /* Ignore unexpected block. */ ++ else if (grub_be_to_cpu16 (tftph->u.data.block) > data->block + 1) ++ grub_dprintf ("tftp", "TFTP unexpected block # %d\n", tftph->u.data.block); ++ else ++ { ++ unsigned size; ++ ++ if (file->device->net->packs.count < 50) ++ { + err = ack (data, data->block + 1); +- else +- { +- file->device->net->stall = 1; +- err = 0; +- } +- if (err) +- return err; +- +- err = grub_netbuff_pull (nb_top, sizeof (tftph->opcode) + +- sizeof (tftph->u.data.block)); +- if (err) +- return err; +- size = nb_top->tail - nb_top->data; +- +- data->block++; +- if (size < data->block_size) +- { +- if (data->ack_sent < data->block) +- ack (data, data->block); +- file->device->net->eof = 1; +- file->device->net->stall = 1; +- grub_net_udp_close (data->sock); +- data->sock = NULL; +- } +- /* Prevent garbage in broken cards.

The http server has a 10 minute timeout, so if we can't get our 250mb +image transferred fast enough our provisioning fails, which is not ideal. So +add tcp window scaling on open connections and set the window size to 1mb.
