* libutils/Unicode.cpp: Correct length computation and add checks for utf16->utf8Sergio Giro2016-07-211-2/+2
| | | | | | | | | | | | | Inconsistent behaviour between utf16_to_utf8 and utf16_to_utf8_length is causing a heap overflow. Correcting the length computation and adding bound checks to the conversion functions. Test: ran libutils_tests Bug: 29250543 Change-Id: I6115e3357141ed245c63c6eb25fc0fd0a9a7a2bb (cherry picked from commit c4966a363e46d2e1074d1a365e232af0dcedd6a1)
* Adding a build id check to blob cache.Michael Lentine2015-05-181-0/+6
| | | | | | | | | | | | | | Add a build id field to the header structure in blob cache. Add build id support with reading and writing the cache. When the cache gets written it writes the build id at the end of the header. When read it checks to see if there is a match between the current version and the version in the cache. If not, it invalidates the cache which would typically only occur during an ota update. Also remove blob cache from the host build. bug: 18262905 Change-Id: I753b1de1986703a4c1c8691b9d2bb533b2546143

* | Fix issues related to removing Looper callbacks after close.Jeff Brown2015-03-121-1/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When a file descriptor is closed before removing it from the epoll set, it will normally be removed automatically from the epoll set by the kernel. However if there exists a duplicate then the original file descriptor may remain in the set and continue to receive events until all duplicates have been closed. Unfortunately due to kernel limitations we need to rebuild the epoll set from scratch because it may contain an old file handle that we are now unable to remove since its file descriptor is no longer valid. No such problem would have occurred if we were using the poll system call instead, but that approach carries others disadvantages. Bug: 19715279 Change-Id: If1ab8ebda0825755a416d513e888942a02ee3948
* | Fixed subtle bugs related to file descriptor recycling.Jeff Brown2015-03-111-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Added code to protect against situations that may occur when a Looper callback has the side-effect of closing the file descriptor that it is watching before it returns. This code pattern is very convenient for implementation but it does expose issues in how the list of callbacks is maintained. In particular, we need to watch out for file descriptors which have been reused. This change may resolve previously unexplained ANRs associated with log messages such as: "Error modifying epoll events for fd 44, errno=2" Bug: 10349083 Change-Id: I20eedf6ffbdeda382653ca0104962505194741b0
* | Rename Looper::isIdling() to isPolling() to resolve confusion.Jeff Brown2015-03-111-5/+6
|/ | | | | | | | | The loop isn't technically idle at this time, it's just checking whether any file descriptors have pending events. However it's still a good signal as to whether the loop is alive. Bug: 19532373 Change-Id: I555c473e70ffd8a56e1b10aa60026eb674a16de9
* Remove useless refCounting from FileMap.Narayan Kamath2015-02-231-16/+2

| | | | | | | | | | | | | | | | | | | | | | As well intentioned as these were, uint16_t and C++11's char16_t are _not_ actually compatible. They are not implicitly convertible, and they mangle differently, so they are not even ABI compatible. In our now wonderous world of C++11, no one should be using these, so just kill them.

| * Move winsock2.h in front of a potential windows.h include.Stephen Hines2014-11-081-0/+4
| | | | | | | | | | | | | | | | | | | | | | Files that included FileMap.h (possibly transitively), before including ByteOrder.h (which pulls in winsock2.h directly), will experience a compiler warning/error from the latest mingw headers. This happens because the headers require that winsock2.h come before windows.h in all cases. The simplest (and most error-proof) fix for now is to include winsock2.h before this use of windows.h.
