Subject: [PATCH] Make grub_strtol() "end" pointers have safer const
qualifiers. (v2)
Currently the string functions grub_strtol(), grub_strtoul(), and
grub_strtoull() don't declare the "end" pointer in such a way as to
require the pointer itself or the character array to be immutable to the
implementation, nor does the C standard do so in its similar functions,
though it does require us not to change any of it.
The typical declarations of these functions follow this pattern:
long
strtol(const char * restrict nptr, char ** restrict endptr, int base);
Much of the reason for this is historic, and a discussion of that
follows below, after the explanation of this change. (GRUB currently
does not include the "restrict" qualifiers, and we name the arguments a
bit differently.)
The implementation is semantically required to treat the character array
as immutable, but such accidental modifications aren't stopped by the
compiler, and the semantics for both the callers and the implementation
of these functions are sometimes also helped by adding that requirement.
This patch changes these declarations to follow this pattern instead:
long
strtol(const char * restrict nptr,
const char ** const restrict endptr,
int base);
This means that if any modification to these functions accidentally
introduces either an errant modification to the underlying character
array, or an accidental assignment to endptr rather than *endptr, the
compiler should generate an error. (The two uses of "restrict" in this
case basically mean strtol() isn't allowed to modify the character array
by going through *endptr, and endptr isn't allowed to point inside the
array.)
It also means the typical use case changes to:
char *s = ...;
const char *end;
long l;
l = strtol(s, &end, 10);
Or even:
const char *p = str;
while (p && *p) {
long l = strtol(p, &p, 10);
...
}
This fixes 26 places where we discard our attempts at treating the data
safely by doing:
const char *p = str;
long l;
l = strtol(p, (char **)&ptr, 10);
It also adds 5 places where we do:
char *p = str;
while (p && *p) {
long l = strtol(p, (const char ** const)&p, 10);
...
/* more calls that need p not to be pointer-to-const */
}
While moderately distasteful, this is a better problem to have.
With one minor exception, I have tested that all of this compiles
without relevant warnings or errors, and that /much/ of it behaves
correctly, with gcc 9 using 'gcc -W -Wall -Wextra'. The one exception
is the changes in grub-core/osdep/aros/hostdisk.c , which I have no idea
how to build.
Because the C standard defined type-qualifiers in a way that can be
confusing, in the past there's been a slow but fairly regular stream of
churn within our patches, which add and remove the const qualifier in many
of the users of these functions. This change should help avoid that in
the future, and in order to help ensure this, I've added an explanation
in misc.h so that when someone does get a compiler warning about a type
error, they have the fix at hand.
The reason we don't have "const" in these calls in the standard is
purely anachronistic: C78 (de facto) did not have type qualifiers in the
syntax, and the "const" type qualifier was added for C89 (I think; it
may have been later). strtol() appears to date from 4.3BSD in 1986,
which means it could not be added to those functions in the standard
without breaking compatibility, which is usually avoided.
The syntax chosen for type qualifiers is what has led to the churn
regarding usage of const, and is especially confusing on string
functions due to the lack of a string type. Quoting from C99, the
syntax is:
declarator:
pointer[opt] direct-declarator
direct-declarator:
identifier
( declarator )
direct-declarator [ type-qualifier-list[opt] assignment-expression[opt] ]
...
direct-declarator [ type-qualifier-list[opt] * ]
...
pointer:
* type-qualifier-list[opt]
* type-qualifier-list[opt] pointer
type-qualifier-list:
type-qualifier
type-qualifier-list type-qualifier
...
type-qualifier:
const
restrict
volatile
So the examples go like:
const char foo; // immutable object
const char *foo; // mutable pointer to object
char * const foo; // immutable pointer to mutable object
const char * const foo; // immutable pointer to immutable object
const char const * const foo; // XXX extra const keyword in the middle
const char * const * const foo; // immutable pointer to immutable
// pointer to immutable object
const char ** const foo; // immutable pointer to mutable pointer
// to immutable object
Making const left-associative for * and right-associative for everything
else may not have been the best choice ever, but here we are, and the
inevitable result is people using trying to use const (as they should!),
putting it at the wrong place, fighting with the compiler for a bit, and
then either removing it or typecasting something in a bad way. I won't
go into describing restrict, but its syntax has exactly the same issue
as with const.
Anyway, the last example above actually represents the *behavior* that's
required of strtol()-like functions, so that's our choice for the "end"
pointer.

Subject: [PATCH] efi/http: Export {fw,http}_path variables to make them global
The fw_path environment variable is used by http_configure() function to
determine the HTTP path that should be used as prefix when using relative
HTTP paths. And this is stored in the http_path environment variable.
Later, that variable is looked up by grub_efihttp_open() to generate the
complete path to be used in the HTTP request.
But these variables are not exported, which means that are not global and
so are only found in the initial context.
This can cause commands like configfile that create a new context to fail
because the fw_path and http_path variables will not be found.

Subject: [PATCH] efi/http: Enclose literal IPv6 addresses in square brackets
According to RFC 2732 (https://www.ietf.org/rfc/rfc2732.txt), literal IPv6
addresses must be enclosed in square brackets. But GRUB currently does not
do this and is causing HTTP servers to send Bad Request (400) responses.
For example, the following is the HTTP stream when fetching a config file:
HEAD /EFI/BOOT/grub.cfg HTTP/1.1
Host: 2000:dead:beef:a::1
Accept: */*
User-Agent: UefiHttpBoot/1.0
HTTP/1.1 400 Bad Request
Date: Thu, 05 Mar 2020 14:46:02 GMT
Server: Apache/2.4.41 (Fedora) OpenSSL/1.1.1d
Connection: close
Content-Type: text/html; charset=iso-8859-1
and after enclosing the IPv6 address the HTTP request is successful:
HEAD /EFI/BOOT/grub.cfg HTTP/1.1
Host: [2000:dead:beef:a::1]
Accept: */*
User-Agent: UefiHttpBoot/1.0
HTTP/1.1 200 OK

Subject: [PATCH] efi/net: Allow to specify a port number in addresses
The grub_efi_net_parse_address() function is not covering the case where a
port number is specified in an IPv4 or IPv6 address, so will fail to parse
the network address.
For most cases the issue is harmless, because the function is only used to
match an address with a network interface and if fails the default is used.
But still is a bug that has to be fixed and it causes error messages to be
printed like the following:
error: net/efi/net.c:782:unrecognised network address '192.168.122.1:8080'
error: net/efi/net.c:781:unrecognised network address '[2000:dead:beef:a::1]:8080'

The grub_efi_string_to_ip4_address() function wrongly assumes that an IPv6
address is an IPv4 address, because it doesn't take into account the case
of a caller passing an IPv6 address as a string.
This leads to the grub_efi_net_parse_address() function to fail and print
the following error message:

Subject: [PATCH] efi/net: Print a debug message if parsing the address fails
Currently if parsing the address fails an error message is printed. But in
most cases this isn't a fatal error since the grub_efi_net_parse_address()
function is only used to match an address with a network interface to use.
And if this fails, the default interface is used which is good enough for
most cases. So instead of printing an error that would pollute the console
just print a debug message if the address is not parsed correctly.
A user can enable debug messages for the efinet driver to have information
about the failure and the fact that the default interface is being used.

Subject: [PATCH] blscfg: return NULL instead of a zero-length array in
bls_make_list()
The bls_make_list() function returns a list of all the values for a given
key and if there is none a NULL pointer should be returned. But currently
is returnin a zero-length array instead.
This makes the callers to wrongly assume that there are values for a key
and populate wrong menu entries. For example menu entries are populated
with an initrd command even if there is no initrd fiel in the BLS file.
