2016-01-22minzip: Add support for >2GB zipfilenkk713-10/+15
normal zip limit is 4GB, but due to signed variables it will only access 2GB (32bit signed integer is from -2GB to +2GB). these changes allow for a theoretical limit of 4GB zips to be flashed. RAM restrictions still apply, and on a 32bit system it's likely to max out at approx 2.8GB flashable zip, above that mmap will probably fail. Note: the flashable zip also needs a compatible update-binary which include these changes. (this also applies to both aroma installer if it's being used).

2015-03-13Revert "Force sync files written by minzip."Andrew Dodd1-8/+2
This has been causing significant performance degradation when flashing updates for the entirety of 5.0. I was originally hesitant to do this since we don't want unsynced files on an update, however - Our updater-script unmounts /system at the end of installation, which will force a sync. As a result the issue Google was trying to fix won't be present for our ZIPs. This reverts commit a6c142f2a579ea5e7cdfbc88e6a061c55029265a. Change-Id: I89b22e2677c4eda4d3e6338adc0046bf754d43b2

2014-12-10Use one mizip for allEthan Yonker2-1/+12
The new minzip did not compile in older trees due to needing mmap64. For older trees we will just use mmap instead. Remove all files and code pertaining to minzipold. Updater should now build properly in older trees as well. Eliminate use of PLATFORM_VERSION in favor of PLATFORM_SDK_VERSION which should be more consistent and reliable.

2014-05-09Allow 0-byte files in full OTAs.Michael Runge1-1/+3
Currently, the writeProcessFunction fails when there are zero bytes to write, potentially returning errno from a previous operation, or hanging indefinitely while it waits for a >0 result on a write of size 0.

2014-01-16do verification and extraction on memory, not filesDoug Zongker4-137/+186
Changes minzip and recovery's file signature verification to work on memory regions, rather than files. For packages which are regular files, install.cpp now mmap()s them into memory and then passes the mapped memory to the verifier and to the minzip library. Support for files which are raw block maps (which will be used when we have packages written to encrypted data partitions) is present but largely untested so far.

2013-07-19Update OTA installer to understand SELinux filesystem labelsNick Kralevich2-3/+8
Modify the OTA installer to understand SELinux filesystem labels. We do this by introducing new set_perm2 / set_perm2_recursive calls, which understand SELinux filesystem labels. These filesystem labels are applied at the same time that we apply the UID / GID / permission changes. For compatibility, we preserve the behavior of the existing set_perm / set_perm_recursive calls. If the destination kernel doesn't support security labels, don't fail. SELinux isn't enabled on all kernels. Bug: 8985290 Change-Id: I99800499f01784199e4918a82e3e2db1089cf25b

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.

2010-02-01add a one-argument version of package_extract_fileDoug Zongker2-0/+44
Add a version of package_extract_file that returns the file data as its return value (to be consumed by some other edify function that expects to receive a bunch of binary data as an argument). Lets us avoid having two copies of a big file in memory (extracting it into /tmp, which is a ramdisk, and then having something load it into memory) when doing things like radio updates.

2009-05-08undo temporary alignment hackDoug Zongker2-48/+8
Remove the memory alignment that mysteriously made OTA installs work, in anticipation of a kernel that fixes the actual problem. Handle EINTR properly.
2009-05-06align data passed to write() on 32k boundariesDoug Zongker2-17/+55
In donut, OTA installation often encounters the write() system call doing short writes -- which is legal but unexpected -- or failing with ENOSPC when plenty of space is available. Passing aligned memory buffers to write() appears to prevent (or at least reduce the frequency) of these problems. b/1833052 has been filed to look at the underlying problem, but this change aligns buffers we use with write() so we can OTA for now (or see if this problem still occurs).
2009-04-30handle short writes when unzipping filesDoug Zongker1-11/+27
minzip fails if write() doesn't write all the data in one call. Apparently this was good enough before, but it causes OTAs to fail all the time now (maybe due to the recently-submitted kernel)? Change code to attempt continuing after short writes.
