* Fix a bunch of small system/core bugs.Elliott Hughes2013-10-292-1/+3
| | | | | | | | | | | | | | | | | | | | | Missing frees in: adb/file_sync_client.c fastboot/fastboot.c libsparse/output_file.c Missing closedirs in: adb/file_sync_service.c cpio/mkbootfs.c libcutils/dir_hash.c Potential buffer overrun in: gpttool/gpttool.c Incorrect NULL check in: libsparse/backed_block.c Bug: https://code.google.com/p/android/issues/detail?id=61564 Change-Id: If97838a9e73a77aef7f416c31c237ce1fca4ce21
* libsparse: Use BIONIC implementation of mmap64()Daniel Leung2013-09-181-9/+0

* libsparse: Fix null pointer issueHong-Mei Li2013-04-011-0/+3
| | | | | | | Fix the issue that "out" pointer is dereferenced without checking. Change-Id: I76a57ad7309841218231346f4807ef2be8628737 Signed-off-by: Hong-Mei Li <a21834@motorola.com>
* Support for multiple modules with the same name is going away.Joe Onorato2012-08-151-37/+35

* libsparse: fix 32 bit overflow when calculating last chunkColin Cross2012-07-231-1/+1
| | | | | | | last_block * s->block_size can overflow when writing large filesystems, cast to 64 bits before multiplying. Change-Id: I3e54097852ce7d0fd271eab53d65e666284898e4
* libsparse: rename symbols that conflict with libext4_utilsColin Cross2012-07-093-14/+14
| | | | | | | | | Until ext4_utils switches to using libsparse, libext4_utils defines some of the same symbols as libsparse. Fastboot links statically against both of them, and there is no easy way to make the symbols hidden, so just rename them in libsparse. Change-Id: Idc2cfe20efe3c3a7fb8233f453a89bbbeb0dcc8b
* libsparse: add sparse_file_lenColin Cross2012-07-092-0/+38
| | | | | | | | Add sparse_file_len, which will compute the size of data that would be produced if sparse_file_write was called. Useful combined with sparse_file_callback. Change-Id: I1a156d1071760f5559483954a5c62ffc20298703
* libsparse: add function to resparse a file and a utility to use itColin Cross2012-07-098-22/+365
| | | | | | | | | Add sparse_file_repsarse, which splits chunks in an existing sparse file such that the maximum size of a chunk, plus a header and footer, is smaller than the given size. This will allow multiple smaller sparse files to result in the same data as a large sparse file. Change-Id: I177abdb958a23d5afd394ff265c5b0c6a3ff22fa
* libsparse: add callback output file typeColin Cross2012-07-094-28/+175
| | | | | | | | | | | Add a new output file subclass that will call a callback for each block as it is written. Will be used to measure the space used by each sparse block to allow resparsing files. Also add sparse_file_callback, which will write out a sparse file by calling the provided write function. Change-Id: I18707bd9c357b68da319cc07982e93d1c2b2bee2
* libsparse: pseudo-subclass output_file for normal and gz filesColin Cross2012-07-092-81/+158
| | | | | | | | | Create two subclasses of output_file that can handle normal and gzipped files, and refactor open_output_fd. Will allow adding support for an output_file type that is not file backed. Change-Id: I26744c74d13f205cf17df1ea9caac1eea9c57357
* libsparse: add sparse_file read and convert tools to use itColin Cross2012-07-095-535/+643
| | | | | | | | | | | | | | Abstract the logic from simg2img into libsparse, and add logic for reading a regular image into libsparse. simg2img then becomes a simple wrapper around libsparse. img2simg was not actually making the file sparse, it was using sparse files to create multiple files that could be pieced back together. Replace it with a simple wrapper around libsparse. Its functionality will be replaced by an simg2simg that can resparse a file into smaller chunks. Change-Id: I266f70e1c750454183ce46c71a7bb66bbb033a26
* libsparse: fix windows image writingColin Cross2012-07-092-3/+38
| | | | | | Fix write_fd_chunk on windows. Uses malloc and read instead of mmap. Change-Id: I75f10db2e04f19e7f3a6ff46b6978d143cb5254e
* libsparse: merge adjacent blocks of the same typeColin Cross2012-07-093-9/+76
| | | | | | | | | | | | When a block is added that is adjacent to another block and of the same type, merge it. This will be useful for converting regular images to sparse images, allowing the reader to add a single block at a time and letting libsparse optimize into larger blocks as it goes. Does not support merge two blocks that are backed by a data pointer, only blocks that are backed by a file for now. Change-Id: I95aa231714cbe01ac194e868c21385806c0bdb97
* libsparse: add error reporting functionsColin Cross2012-07-095-1/+59
| | | | Change-Id: I2f21355b6c5339d1d724b4c121ea30d575b2d366
* libsparse: add support for including fdsColin Cross2012-07-096-17/+99
| | | | | | | | Add sparse_file_add_fd to include all or part of the contents of an fd in the output file. Will be useful for re-sparsing files where fd will point to the input sparse file. Change-Id: I5d4ab07fb37231e8e9c1912f62a2968c8b0a00ef
* libsparse: cleanupsColin Cross2012-07-096-473/+447
| | | | | | | | | | Move block loops into sparse.c with iterator helpers in backed_block.c. Simplify chunk writing by moving skip chunk calls from output_file.c to sparse.c. Rename variables to be consistent with new naming. Remove use of u8, u32, u64. Change-Id: Ic138ad58bef9f96239266ccee12ee83ea285e7eb
* libsparse: remove static variablesColin Cross2012-07-094-67/+87
| | | | | | | Removes static variables in backed_block.c to allow multiple sparse files to be open at the same time. Change-Id: I012d8a424c6e21a7352408416adb7c72ee8add21
* system/core: move libsparse into system/coreColin Cross2012-07-0915-0/+2320
This moves an exact copy of libsparse from system/extras/ext4_utils/libsparse to system/core/libsparse in preparation for linking tools in system/core against it. Change-Id: If664e4fcfd6612844ac745589beb1517e7f9fe58
