2021-05-03Update to v5.12 kernel headers.Christopher Ferris
Kernel headers coming from: Git: https://android.googlesource.com/kernel/common/ Branch: android-mainline Tag: android-mainline-5.12 Test: Boots flame device and runs bionic unit tests. Test: Boots acloud device and runs bionic unit tests. Change-Id: I8ac107ce9d4978be3ef9517b90ad6ecafd06785a
2021-04-21Merge "Fix last python3 issues."Christopher Ferris
2021-04-20Fix last python3 issues.Christopher Ferris
Includes pointing to the python3 version of the clang bindings. Also, remove stale .gitignore line. Test: Ran bionic/libc/kernel/tools/update_all.py and verified Test: the files generated the same exact way. Change-Id: I4eb9dd7382bca013f70d921b6ef48c7e7478615a
2021-04-20Fix overly-zealous strip.Dan Albert
The argument to this is the characters to strip, so `line.strip(line)` just returns the empty string. Test: None? Bug: None Change-Id: I4f62bffcd00936e4eef837a28b78023fcad54bb0
2021-04-19Update for python3.Christopher Ferris
This fixes all of the problems with our kernel scripts, but not the clang python script problems. I also removed the updateGitFiles function since that code was just silently failing any way. I replaced all calls with updateFiles. Test: Ran script using python2 to verify it still works. Test: Run script in python3 verifying that it starts to run. Change-Id: I223a31a8324c59e6bc4067f48a6110361b3e26e8
2021-04-15Force everything to use python3 for consistency.Elliott Hughes
Rather than "whatever people have installed as 'python' on their machine". I've removed check-symbols.py because that's been broken for years and we never even noticed, and I'm not sure it's worth fixing. Test: treehugger, manual Change-Id: Ieb996bbdf790a18d4b1fb46a409cc240ba2a2a49
2021-03-18Update kernel update documentation.Christopher Ferris

2020-12-03Clean up header files from kernel directory.Christopher Ferris
Add a make distclean for each supported arch before generating headers and at the end so these files are not left hanging around in the kernel directory. Bug: 174795055 Test: Verified all generated files are deleted after running. Test: Verified this generates the exact same files as before this change. Change-Id: I0f66f580af2ea50c190eb532032017e782d7cae6
2020-10-19Update to v5.9 kernel headers.Christopher Ferris
Kernel headers coming from: Git: https://android.googlesource.com/kernel/common/ Branch: android-mainline Tag: android-mainline-5.9 Test: Boots cuttlefish 64bit, passes 32 bit and 64 bit bionic unit tests. Change-Id: Ib5503355b238ea75595538e63eb000c867d06ef7
2020-08-04Update to v5.8 kernel headers.Christopher Ferris
Kernel headers coming from: Git: https://android.googlesource.com/kernel/common/ Branch: android-mainline Tag: android-mainline-5.8 Test: NA Change-Id: I2231c877589820fc09800a200cf4ac62ba74b04c
2020-07-31More cleanup for #inclusivefixit.Elliott Hughes
Found manually with grep, since the script seems to miss stuff. Test: treehugger Change-Id: I5933cbade9792801d4a0bec1ccb077efa6ad8fbc
2020-06-04Update the generate script.Christopher Ferris
The arm kvm.h file has been deprecated, so nobody should be including it. Therefore, remove the hack to copy the file out of the tools directory. Also, update to remove the arm kvm.h file. Test: Ran generate and update script and verified only the arm kvm.h Test: was deleted. Test: Builds and boots on a walleye. Change-Id: I95dcc8877bdb2da2858b0b9d0aa95d1d2072cf9a
2020-06-02Update to v5.7 kernel headers.Christopher Ferris
Kernel headers coming from: Git: https://android.googlesource.com/kernel/common/ Branch: android-mainline Tag: android-mainline-5.7 Update the generate_uapi_headers.sh where the types.h file is now in the right place, but kvm.h is not. Test: Booted cuttlefish/bonito. Test: Ran bionic-unit-tests on cuttlefish/bonito. Change-Id: Ice9ce370a658e320b80f564b34a4431927fcf100
2020-04-10Update to v5.6 kernel headers.Christopher Ferris
Kernel headers coming from: Git: https://android.googlesource.com/kernel/common/ Branch: android-mainline Tag: android-mainline-5.6 Add a new method for removing structures. This is to deal with the kernel headers changing some definitions of timeval to __kernel_old_timeval and itimerval to __kernel_old_itimerval. Remove the __kernel_old_XX strutures and change the other structures to the previous definitions. This only works so long as these structures stay the same, if they diverge, then a different strategy will need to be implemented. Test: Booted cuttlefish/walleye. Test: Ran bionic-unit-tests on cuttlefish/walleye. Change-Id: I0a61f4fa6e4155c602e0414d9b38c2e1637829af
2020-02-07Update to v5.5 kernel headers.Christopher Ferris
Kernel headers coming from: Git: https://android.googlesource.com/kernel/common/ Branch: android-mainline Tag: android-mainline-5.5 Test: Boots on walleye. Test: Ran bionic-unit-tests on walleye. Test: Boots on cuttlefish. Test: Ran bionic-unit-tests on cuttlefish. Change-Id: I57387d3c31e0ba5ad125ffe291cecf365c7b374e Merged-In: I57387d3c31e0ba5ad125ffe291cecf365c7b374e
2020-02-03Stop generating unused headers.Elliott Hughes
These just cause confusion because they often have different values/layouts, but they're never actually used. Test: treehugger Change-Id: I424034088e017c919f62fcefa7d6d3f903f31cfb
2020-01-30Merge "Fully disable clang format where needed."Christopher Ferris
2020-01-30Fully disable clang format where needed.Christopher Ferris
Even with formatting off, clang still tries to rearrange the include files or the using statements, so disable that too. Test: Verified that the include directories are not rearranged. Change-Id: I991a1b2bfa94a8202c5a486664658d654f1c7811
2020-01-29_FILE_OFFSET_BITS=64 support for fcntl.Elliott Hughes
On Android, fcntl is always implemented by fcntl64(2). This means that an LP32 binary can `fcntl(F_SETLK, struct flock)` (because fcntl64(2) passes through to the 32-bit fcntl(2) to handle F_SETLK), and it can also `fcntl(F_SETLK64, struct flock64)`. What it can't do before this patch is set _FILE_OFFSET_BITS=64 and then `fcntl(F_SETLK, struct flock)` where that `struct flock` is actually implicitly `struct flock64`. Move the kernel uapi structs out of the way, define them ourselves based on __LP64__ and _FILE_OFFSET_BITS, and fix up the relevant F_ constants. (Also add a .clang-format to turn off clang-format in libc/include/.) Bug: N/A Test: treehugger (and strace!) Change-Id: Iccd6c83d9133e1efcf93a7b49a6ae0f1bbd3d58b
2020-01-29Link .clang-format file to system/core one.Christopher Ferris
Use the .clang-format-2 found in system/core instead of this which is not actually being used. Also, enable clang-format running by default. All upstream directories are marked as ignoring formatting so that their source files are not modified. Test: NA Change-Id: Icee6030f373fa5f072df162f97e6f34320e3d89a
2019-12-16Merge "Update documentation around kernel header imports."Christopher Ferris

Test: NA Change-Id: I8866ef30efbc565e8996c574a9f895c574cd8e55
2019-12-12Update to android-mainline kernel headers v5.4.Christopher Ferris
Update generate_uapi_headers.sh to checkout the android mainline kernel. Also, add a small modification to look for the kernel directory in common not linux-stable. Remove deprecated android headers from android/uapi/linux. Also, remove f_accessory.h since it's in the android mainline kernel. Test: Builds and runs on walleye. Change-Id: Ia371305e19f56e6bcc2db6d5b4d299819f07ffc6
2019-10-03Update to kernel headers v5.3.2.Christopher Ferris
Test: Builds and run unit tests on taimen/cuttlefish. Change-Id: I6ebd8f179d159ac974555e8edca588083e8081b3
2019-09-03Update to kernel headers v5.2.11.Christopher Ferris
Test: Build and boots on taimen. Test: Bionic unit tests all pass on taimen. Change-Id: I80abb6f9abbff9ca20ce6c7c912a259b5ca86fa2
2019-08-05Update to kernel headers v5.2.6.Christopher Ferris
Also, fix a bug in update_all.py when the syscalls file does not change. Test: Builds and boots on a taimen. Change-Id: If85b00daef2c176f804a0861894f5bbca9c6d5df
2019-07-08Update to kernel headers v5.2.Christopher Ferris
Test: Booted a taimen, ran unit bionic unit tests. Change-Id: I3522c59793bbcef98ea515996a481d92f14b8816
2019-05-20Update to kernel headers to v5.1.3.Christopher Ferris
Test: Builds and boots taimen. Test: Ran bionic unit tests. Change-Id: Ieaca8709d568f075df8cac60c9da2c0ed1916963
2019-04-16Generate assembler system call stubs via genrule.Elliott Hughes
There's no need to check in generated code. Test: builds & boots Change-Id: Ife368bca4349d4adeb0666db590356196b4fbd63
2019-04-15clean_header: Run outside of $ANDROID_BUILD_TOPDaniel Mentz
Enable the use case where we run clean_header.py from outside of $ANDROID_BUILD_TOP. Previously, this script required the current working directory to be under $ANDROID_BUILD_TOP. Running it from a different directory resulted in the following error message: clean_header.py: error: Not in android tree pointed at by ANDROID_BUILD_TOP (....) Change-Id: I48210ea1a0033228a9aaa4124d28247b07cee6d4
2019-04-15clean_header: Fix error handling for no-such-file caseDaniel Mentz
The function cleanupFile should always return a single value (as opposed to a tuple or list). In addition, if it encounters an error, it is expected to return a value that evaluates to False. As it stands, however, it returns (None, None) in certain error cases. Change this function to return None, in those cases. We previously saw the following error message, when we tried to run clean_header.py on a non-existent file. Traceback (most recent call last): File "clean_header.py", line 208, in <module> b.updateGitFiles() File "utils.py", line 164, in updateGitFiles self._writeFile(dst) File "utils.py", line 136, in _writeFile f.write(self.new_data[dst]) TypeError: expected a string or other character buffer object Change-Id: I5f717dd1a4388f598f0fd4bfd5e6129017de9095
2019-04-12Merge "Move kernel README files to Markdown."Treehugger Robot
2019-04-11<bits/glibc-syscalls.h>: only regenerate when we have new uapi headers.Elliott Hughes
Test: update_all.py Change-Id: Iaa92dce263197f5a0e7d2dce5e00a31372dcb3e9

2019-03-29clean_header: Don't print extraneous newline charDaniel Mentz
Don't print an extraneous newline character at the end of the include file if clean_header.py is used in the non-update mode. This is necessary to achieve consistent results in the update and non-update modes. Running clean_header in the non-update mode and redirecting the output to a file should have the same result as using the update mode and have the script write to the file directly. Change-Id: I6b176c5365840d66e4499bacd205f1fa77302a2b
2019-03-29clean_header: Write to correct dst_fileDaniel Mentz
Write to correct dst_file when in update mode. This enables use cases like the following: ../../../bionic/libc/kernel/tools/clean_header.py -k original-kernel-headers/ -d kernel-headers/ -u linux/ion.h Previously, we had to cd into kernel-headers/ and then run ../../../../bionic/libc/kernel/tools/clean_header.py -k ../original-kernel-headers/ -d . -u linux/ion.h because the tool didn't allow the relative path to be different from the destination path.

2019-01-15Update to v4.20.1 kernel headers.Christopher Ferris
This includes one manual change: In the file bionic/libc/kernel/uapi/linux/in.h, the macro IN_BADCLASS was not definied correctly. Change the macro from: #define IN_BADCLASS(a) ((((long int) (a)) == 0xffffffff) to: #define IN_BADCLASS(a) (((long int) (a)) == (long int)0xffffffff) This change is being pushed to the upstream kernels. Test: Builds and boots. Change-Id: Ia304773a9dc6789b34d9769d73742384d6afb571 Merged-In: Ia304773a9dc6789b34d9769d73742384d6afb571 (cherry picked from commit 967fb01cce73591281e7804e2c0fa9f83b618f5b)
2019-01-10Update kernel headers with new parser.Christopher Ferris
Test: Builds. Change-Id: I3f0714d53ac893ccc3e66f7a92d0ea7a6737f1c3
2019-01-10Rewrite removeVarsAndFuncs.Christopher Ferris
The current version has these bugs: - Adding a semicolon after a function results in the removal of structures following the function. - Function like macros get removed on accident rather than on purpose. - It removes extern "C" { completely, which might not be a bug, but doesn't seem right. I couldn't easily fix any of these problems because the code depends heavily on the header being correct. New unit tests added for the function to cover all of these cases. A follow-on CL will include the updated headers. Bug: 112290385 Test: Passes all new unit tests. Test: When run on the current kernel headers, the generated headers are Test: nearly the same, missing data is being added. Change-Id: Ib22a5f2e78873544e8a9d54e385af1156b2a72bb
2018-10-30Update to v4.19 kernel headers.Christopher Ferris
Test: Builds and boots. Change-Id: I99a9ed79666e143b47f02ca4e59eed94f69b7e4a (cherry picked from commit a981e2e52e2e95a65fa9c9b6fb16dcb4c83dd576)
2018-10-26Fix handling of #elif.Christopher Ferris
When a construct like: if defined(something) blocks1 elif 1 blocks2 else blocks3 endif The parser would put the first clause but then simply omit the elif and put all of blocks2 without a terminating #endif. The code also did something similar when the #else was an #endif. Also convert all of the unit tests to real unit tests and only run them if you run cpp.py by itself. Added new unit tests to cover the new cases. Test: Ran cpp.py unit tests. Test: Reran update_all.py and verified nothing changed, and that running Test: it on the new kernel headers that exposed this problem. Change-Id: Ie168511303c4e15afdb60c37baef75a966ca29a8
2018-06-27Update to v4.17.3 kernel headers.Christopher Ferris
Test: Builds, boots on a walleye. Change-Id: I389d8b61ec00ea309e38d1b1a2e0dace48c21edb
2018-05-24Modify the script to use the linux source tree.Christopher Ferris
The current code checks out the android kernel tree. Long ago, we moved to using the linux kernel source code. Modify the script to actually do this. Bug: 6653610 Test: Ran the script using the --download_kernel option and without. Change-Id: I769e769edea272f4f8c9c8d2e76bd336059c66e3
2018-04-24Remove ion.h from bionic uapi headers.Christopher Ferris
Bug: 77976082 Test: Ran the generate script and verified ion.h is deleted. Change-Id: I33b3aeef66f08f35dd496a073931b2fe2c80a1d6
2018-02-22Use the ion.h from the kernel headers.Christopher Ferris
All code that needs to use the frozen version of ion.h header should have a copy, so move to the version as parsed from the real headers. Test: Compiled and boots. Change-Id: If9feae9c163ca64c4862045e86611fd3cf1fc18e
