Subject: [PATCH 04/25] memory.h: Always define strlcpy for glibc based systems

android-config.h file includes on compiler cmdline sets HAVE_STRLCPY
unconditionally, since bionic supports it, its no big deal on android
and also no problem when using musl since implementation exists for musl
too, but glibc does not provide this. So either we include libbsd or use
the implementation provided by android-tools here. We are currently
using the in tree implementation for systems which do not provide it

Subject: [PATCH 10/25] adb: Fix build on big endian systems

The usb_linux_client.c file defines cpu_to_le16/32 by using the C
library htole16/32 function calls. However, cpu_to_le16/32 are used
when initializing structures, i.e in a context where a function call
is not allowed.

It works fine on little endian systems because htole16/32 are defined
by the C library as no-ops. But on big-endian systems, they are
actually doing something, which might involve calling a function,
causing build failures.

To solve this, we simply open-code cpu_to_le16/32 in a way that allows
them to be used when initializing structures.

+/* (From RFC1521 and draft-ietf-dnssec-secext-03.txt)
+   The following encoding technique is taken from RFC 1521 by Borenstein
+   and Freed.  It is reproduced here in a slightly edited form for
+   convenience.
+
+   A 65-character subset of US-ASCII is used, enabling 6 bits to be
+   represented per printable character. (The extra 65th character, "=",
+   is used to signify a special processing function.)
+
+   The encoding process represents 24-bit groups of input bits as output
+   strings of 4 encoded characters. Proceeding from left to right, a
+   24-bit input group is formed by concatenating 3 8-bit input groups.
+   These 24 bits are then treated as 4 concatenated 6-bit groups, each
+   of which is translated into a single digit in the base64 alphabet.
+
+   Each 6-bit group is used as an index into an array of 64 printable
+   characters. The character referenced by the index is placed in the
+   output string.

+
+   Special processing is performed if fewer than 24 bits are available
+   at the end of the data being encoded.  A full encoding quantum is
+   always completed at the end of a quantity.  When fewer than 24 input
+   bits are available in an input group, zero bits are added (on the
+   right) to form an integral number of 6-bit groups.  Padding at the
+   end of the data is performed using the '=' character.
+
+   Since all base64 input is an integral number of octets, only the
+         -------------------------------------------------
+   following cases can arise:
+
+       (1) the final quantum of encoding input is an integral
+           multiple of 24 bits; here, the final unit of encoded
+	   output will be an integral multiple of 4 characters
+	   with no "=" padding,
+       (2) the final quantum of encoding input is exactly 8 bits;
+           here, the final unit of encoded output will be two
+	   characters followed by two "=" padding characters, or
+       (3) the final quantum of encoding input is exactly 16 bits;
+           here, the final unit of encoded output will be three
+	   characters followed by one "=" padding character.

Subject: [PATCH 21/25] libsparse: Split off most of sparse_file_read_normal
 into a helper function

This carves out the core of sparse_file_read_normal and splits it off so
it can be reused in the next patch. No functional change intended.

Subject: [PATCH 22/25] libsparse: Add "hole" mode to sparse_file_read

This adds support for filesystem-level sparse files. These files have
holes which are not stored in the filesystem and when read are full of
zeros. While these zeros may be significant in some types of files,
other types of files may not care about the contents of holes. For
example, most filesystem creation tools write to all the blocks they
care about. Those blocks not written to will remain holes, and can be
safely represented by "don't care" chunks. Using "don't care" chunks
instead of fill chunks can result in a substantial reduction of the time
it takes to program a sparse image.

To accomplish this, we extend the existing "sparse" boolean parameter to
be an enum of mode types. This enum represents the strategy we take when
reading in a file. For the most part the implementation is
straightforward. We use lseek to determine where the holes in the file
are, and then use do_sparse_file_read_normal to create chunks for the
data section. Note that every file has an implicit hole at its end.

Subject: [PATCH 23/25] img2simg: Add support for converting holes to "don't
 care" chunks

This adds support for converting files with holes to "don't care"
chunks. This can result in a substantial reduction in the time it takes
to program an image if it has many holes.

Generally, constants compared to argc have been reduced by one, since we
no longer have the program name as the first argument.

Change-Id: I00750edc07d6415dcc07ae0351e9397b0222b7ba
Upstream-Status: Backport [6150b00b6025918da8c28e5c2f929ecdf480a9d6]

+Subject: [PATCH] memory.h: Always define strlcpy for glibc based systems
+
+android-config.h file includes on compiler cmdline sets HAVE_STRLCPY
+unconditionally, since bionic supports it, its no big deal on android
+and also no problem when using musl since implementation exists for musl
+too, but glibc does not provide this. So either we include libbsd or use
+the implementation provided by android-tools here. We are currently
+using the in tree implementation for systems which do not provide it

+Subject: [PATCH] adb: Fix build on big endian systems
+
+The usb_linux_client.c file defines cpu_to_le16/32 by using the C
+library htole16/32 function calls. However, cpu_to_le16/32 are used
+when initializing structures, i.e in a context where a function call
+is not allowed.
+
+It works fine on little endian systems because htole16/32 are defined
+by the C library as no-ops. But on big-endian systems, they are
+actually doing something, which might involve calling a function,
+causing build failures.
+
+To solve this, we simply open-code cpu_to_le16/32 in a way that allows
+them to be used when initializing structures.

++/* (From RFC1521 and draft-ietf-dnssec-secext-03.txt)
++   The following encoding technique is taken from RFC 1521 by Borenstein
++   and Freed.  It is reproduced here in a slightly edited form for
++   convenience.
++
++   A 65-character subset of US-ASCII is used, enabling 6 bits to be
++   represented per printable character. (The extra 65th character, "=",
++   is used to signify a special processing function.)
++
++   The encoding process represents 24-bit groups of input bits as output
++   strings of 4 encoded characters. Proceeding from left to right, a
++   24-bit input group is formed by concatenating 3 8-bit input groups.
++   These 24 bits are then treated as 4 concatenated 6-bit groups, each
++   of which is translated into a single digit in the base64 alphabet.
++
++   Each 6-bit group is used as an index into an array of 64 printable
++   characters. The character referenced by the index is placed in the
++   output string.

++   Special processing is performed if fewer than 24 bits are available
++   at the end of the data being encoded.  A full encoding quantum is
++   always completed at the end of a quantity.  When fewer than 24 input
++   bits are available in an input group, zero bits are added (on the
++   right) to form an integral number of 6-bit groups.  Padding at the
++   end of the data is performed using the '=' character.
++
++   Since all base64 input is an integral number of octets, only the
++         -------------------------------------------------
++   following cases can arise:
++
++       (1) the final quantum of encoding input is an integral
++           multiple of 24 bits; here, the final unit of encoded
++	   output will be an integral multiple of 4 characters
++	   with no "=" padding,
++       (2) the final quantum of encoding input is exactly 8 bits;
++           here, the final unit of encoded output will be two
++	   characters followed by two "=" padding characters, or
++       (3) the final quantum of encoding input is exactly 16 bits;
++           here, the final unit of encoded output will be three
++	   characters followed by one "=" padding character.

+Subject: [PATCH] libsparse: Add "hole" mode to sparse_file_read
+
+This adds support for filesystem-level sparse files. These files have
+holes which are not stored in the filesystem and when read are full of
+zeros. While these zeros may be significant in some types of files,
+other types of files may not care about the contents of holes. For
+example, most filesystem creation tools write to all the blocks they
+care about. Those blocks not written to will remain holes, and can be
+safely represented by "don't care" chunks. Using "don't care" chunks
+instead of fill chunks can result in a substantial reduction of the time
+it takes to program a sparse image.
+
+To accomplish this, we extend the existing "sparse" boolean parameter to
+be an enum of mode types. This enum represents the strategy we take when
+reading in a file. For the most part the implementation is
+straightforward. We use lseek to determine where the holes in the file
+are, and then use do_sparse_file_read_normal to create chunks for the
+data section. Note that every file has an implicit hole at its end.
+

+Subject: [PATCH] memory.h: Always define strlcpy for glibc based systems
+
+android-config.h file includes on compiler cmdline sets HAVE_STRLCPY
+unconditionally, since bionic supports it, its no big deal on android
+and also no problem when using musl since implementation exists for musl
+too, but glibc does not provide this. So either we include libbsd or use
+the implementation provided by android-tools here. We are currently
+using the in tree implementation for systems which do not provide it

+Subject: [PATCH] adb: Fix build on big endian systems
+
+The usb_linux_client.c file defines cpu_to_le16/32 by using the C
+library htole16/32 function calls. However, cpu_to_le16/32 are used
+when initializing structures, i.e in a context where a function call
+is not allowed.
+
+It works fine on little endian systems because htole16/32 are defined
+by the C library as no-ops. But on big-endian systems, they are
+actually doing something, which might involve calling a function,
+causing build failures.
+
+To solve this, we simply open-code cpu_to_le16/32 in a way that allows
+them to be used when initializing structures.

++/* (From RFC1521 and draft-ietf-dnssec-secext-03.txt)
++   The following encoding technique is taken from RFC 1521 by Borenstein
++   and Freed.  It is reproduced here in a slightly edited form for
++   convenience.
++
++   A 65-character subset of US-ASCII is used, enabling 6 bits to be
++   represented per printable character. (The extra 65th character, "=",
++   is used to signify a special processing function.)
++
++   The encoding process represents 24-bit groups of input bits as output
++   strings of 4 encoded characters. Proceeding from left to right, a
++   24-bit input group is formed by concatenating 3 8-bit input groups.
++   These 24 bits are then treated as 4 concatenated 6-bit groups, each
++   of which is translated into a single digit in the base64 alphabet.
++
++   Each 6-bit group is used as an index into an array of 64 printable
++   characters. The character referenced by the index is placed in the
++   output string.

++   Special processing is performed if fewer than 24 bits are available
++   at the end of the data being encoded.  A full encoding quantum is
++   always completed at the end of a quantity.  When fewer than 24 input
++   bits are available in an input group, zero bits are added (on the
++   right) to form an integral number of 6-bit groups.  Padding at the
++   end of the data is performed using the '=' character.
++
++   Since all base64 input is an integral number of octets, only the
++         -------------------------------------------------
++   following cases can arise:
++
++       (1) the final quantum of encoding input is an integral
++           multiple of 24 bits; here, the final unit of encoded
++	   output will be an integral multiple of 4 characters
++	   with no "=" padding,
++       (2) the final quantum of encoding input is exactly 8 bits;
++           here, the final unit of encoded output will be two
++	   characters followed by two "=" padding characters, or
++       (3) the final quantum of encoding input is exactly 16 bits;
++           here, the final unit of encoded output will be three
++	   characters followed by one "=" padding character.

+Subject: [PATCH] libsparse: Add "hole" mode to sparse_file_read
+
+This adds support for filesystem-level sparse files. These files have
+holes which are not stored in the filesystem and when read are full of
+zeros. While these zeros may be significant in some types of files,
+other types of files may not care about the contents of holes. For
+example, most filesystem creation tools write to all the blocks they
+care about. Those blocks not written to will remain holes, and can be
+safely represented by "don't care" chunks. Using "don't care" chunks
+instead of fill chunks can result in a substantial reduction of the time
+it takes to program a sparse image.
+
+To accomplish this, we extend the existing "sparse" boolean parameter to
+be an enum of mode types. This enum represents the strategy we take when
+reading in a file. For the most part the implementation is
+straightforward. We use lseek to determine where the holes in the file
+are, and then use do_sparse_file_read_normal to create chunks for the
+data section. Note that every file has an implicit hole at its end.
+

Description: adb: Make compatible with openssl 1.1
 OpenSSL version 1.1 brought some API changes which broke the build here,
 fix that by accessing rsa->n (and e) directly, using RSA_get0_key instead.
