2014-10-29Use more aggressive sync writing to applypatch.Michael Runge1-8/+36
We have seen cases where the boot partition is patched, but upon recovery the partition appears to be corrupted. Open up all patched files/partitions with O_SYNC, and do not ignore the errors from fsync/close operations. Bug: 18170529 Change-Id: I392ad0a321d937c4ad02eaeea9170be384a4744b
2014-10-07applypatch: add support for BML partitionsConn O'Griofa1-4/+38
This actually uses the EMMC partition access code. In order for this to work, the BML partition name is changed back to the block device name (e.g. "boot" -> "/dev/block/bml9"), and the BML_UNLOCK_ALL ioctl is called before writing. Change-Id: I012f1eca0b486b7465ca38b5db1f513ee8a246ea

2014-02-14remove 'retouch' ASLR supportDoug Zongker1-27/+8
Older versions of android supported an ASLR system where binaries were randomly twiddled at OTA install time. Remove support for this; we now use the ASLR support in the linux kernel. Change-Id: I8348eb0d6424692668dc1a00e2416fbef6c158a2
2013-12-20fix unnecessarily slow writing of EMMC partitionsDoug Zongker1-15/+3
These were attempts to write partitions "conservatively" in hopes of fixing the problems with writing the radio partition on Nexus 4. They didn't work (a kernel patch was needed), but got left in. They make writing of partitions unnecessarily slow (ie, we really shouldn't need to sync() after every 4kb). Roll back most of them, but leave the verification read-back in.

O_DIRECT writes fail with EINVAL due to alignment issues. Change-Id: If8cf38a636313e4f4b4e61e66287dc903c473e5b

2013-07-10recovery: write partitions more conservativelyDoug Zongker1-24/+46
Write and verify partitions using write(2) and read(2) rather than the stdio functions. Read and write in 4kb blocks. When writing, fsync() every 1MB. Bug: 9602014 Change-Id: Ie98ce38e857786fc0f4ebf36bb5ffc93b41bc96f
2013-07-10recovery: try to write EMMC partitions more reliablyDoug Zongker1-6/+72
Nexus 4 has flash errors that manifest during large writes (eg, of the radio partition). Writes of some blocks seem to be dropped silently, without any errors being returned to the user level. Make two changes to the partition-writing code: - break it up into 1MB writes instead of writing partitions with a single fwrite() call. Pause for 50ms in between every chunk. - read the partition back after writing and verify that we read what we wrote. Drop caches before reading so we (hopefully) are reading off the actual flash and not some cache. Neither of these should be necessary.

2013-01-07Add mode when open(O_CREAT) is used.Nick Kralevich1-2/+2
When creating a new file using open(..., O_CREAT), it is an error to fail to specify a creation mode. If a mode is not specified, a random stack provided value is used as the "mode". This will become a compile error in a future Android change. Change-Id: I73c1e1a39ca36bf01704b07302af4971d234b5a8
2012-10-19reduce some recovery loggingDoug Zongker1-6/+21
Make minzip log only a count of files when extracting, not individual filenames. Make patching only chatter about free space if there's not enough and compact the other messages. Only the last 8k of the recovery log gets uploaded; this makes it more likely that we will get all of it. Change-Id: I529cb4947fe2185df82b9da5fae450a7480dcecd
2012-08-21add bonus data feature to imgdiff/imgpatch/applypatchDoug Zongker1-5/+8
The bonus data option lets you give an additional blob of uncompressed data to be used when constructing a patch for chunk #1 of an image. The same blob must be available at patch time, and can be passed to the command-line applypatch tool (this feature is not accessible from edify scripts). This will be used to reduce the size of recovery-from-boot patches by storing parts of the recovery ramdisk (the UI images) on the system partition.

2012-02-28fix failure to free memoryDoug Zongker1-18/+44
The applypatch function is somewhat sloppy about freeing memory (since it was originally a standalone binary). Fix some of that. Change-Id: Ifd44d71ea189c0b5115493119fd57bc37533fd59
2010-09-15(cherry-pick) EMMC support in applypatchDoug Zongker1-102/+175
Let applypatch read and write EMMC partitions as well as MTD ones. This enables incremental updates that include boot image changes, as well as OTA of new recovery partitions. Change-Id: Ib1861219c7ca66dff29ad02d6a0a14e5f03eb4d8
2010-08-13fix bug in applying patchesDoug Zongker1-1/+1
When restarting a patch from crashing in the middle of a large file, we're not finding the correct patch to apply to the copy saved in cache. Change-Id: I41cb2b87d096bb7a28a10c4cf3902facd45d4c9d
2010-08-13remove shadowed variable declarationDoug Zongker1-1/+2
An accidental variable declaration ("int enough_space = ..." instead of "enough_space = " inside a block) shadowing the real one meant we were always using the copy-to-cache path for patching, even when not necessary. Remove it. Enforce an absolute minimum of free space as well, to avoid running into problems patching small files, now that the copy-to-cache path is (inadvertently) well-tested.

2010-02-23refactor applypatch and friendsDoug Zongker1-722/+637
Change the applypatch function to take meaningful arguments instead of argc and argv. Move all the parsing of arguments into main.c (for the standalone binary) and into install.c (for the updater function). applypatch() takes patches as Value objects, so we can pass in blobs extracted from the package without ever writing them to temp files. The patching code is changed to read the patch from memory instead of a file. A bunch of compiler warnings (mostly about signed vs unsigned types) are fixed. Support for the IMGDIFF1 format is dropped. (We've been generating IMGDIFF2 packages for some time now.) Change-Id: I217563c500012750f27110db821928a06211323f
2010-02-18relocate applypatch; add type system and new functions to edifyDoug Zongker1-0/+900
- Move applypatch to this package (from build). - Add a rudimentary type system to edify: instead of just returning a char*, functions now return a Value*, which is a struct that can carry different types of value (currently just STRING and BLOB). Convert all functions to this new scheme. - Change the one-argument form of package_extract_file to return a Value of the new BLOB type. - Add read_file() to load a local file and return a blob, and sha1_check() to test a blob (or string) against a set of possible sha1s. read_file() uses the file-loading code from applypatch so it can read MTD partitions as well. This is the start of better integration between applypatch and the rest of edify. b/2361316 - VZW Issue PP628: Continuous reset to Droid logo: framework-res.apk update failed (CR LIBtt59130) Change-Id: Ibd038074749a4d515de1f115c498c6c589ee91e5
