* sys/fuchsia: fix task syscalls.Marco Vanotti2018-11-292-4/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | This commit fixes two issues related to the task syscalls. The zx_task_resume syscall has been recently removed from zircon[0]. It has been deprecated for some time already. This commit removes the syscall. The `ZX_EXCEPTION_PORT_UNBIND_QUIETLY` option for the syscall `zx_task_bind_exception_port` has been removed recently as well[1]. This commit removes that option from tasks.txt. To test this change, I followed the procedure for building syzkaller for fuchsia: ```shell $ make extract TARGETOS=fuchsia SOURCEDIR=${FUCHSIADIR} $ make generate $ make TARGETOS=fuchsia TARGETARCH=amd64 SOURCEDIR=${FUCHSIADIR} ``` I excluded the changes from make extract. This commit only has the generated files from make generate. [0]: https://fuchsia-review.googlesource.com/c/zircon/+/228712 [1]: https://fuchsia-review.googlesource.com/c/zircon/+/228658

* executor: FreeBSD: fixed endian.h pathmsvoelker2018-11-231-0/+4
| | | | The include statement for endian.h failed on FreeBSD. Changed include statement to syz/endian.h for FreeBSD.
* sys/fuchsia: update VMAR syscallsMarco Vanotti2018-11-212-5/+5
| | | | | | | | | | | | | | | | | | | | | | | * sys/fuchsia: update vmar syscalls. In a previous zircon commit[0], the vmar related syscalls (like `zx_vmar_map`, `zx_vmar_protect` and `zx_vmar_allocate`) changed the order of their parameters, making putting the flags parameter as the second parameter, and renaming it to "options". This commit modifies vmars.txt so that it reflects the latest state of the syscalls in zircon. I also modified the usage in `executor/common_fuchsia.h` I ran make extract, make generate and compiled syzkaller to test this change. [0]: https://fuchsia-review.googlesource.com/c/zircon/+/168060 * sys/fuchsia run make generate This commit is just the result of running make generate after its parent. This regenerates the definitions for the modified VMAR syscalls.
* sys/fuchsia: update fidl mappings.Marco Vanotti2018-11-212-2/+40
| | | | | | | This commit is just a run of make extract + make generate with an up to date fuchsia tree. This commit only updates the fidl definitions, there are some other syscalls that had changed and need to be manually updated (that will come in a future commit).

| | | | | | | | | | | | | | | | | | | | | | | | Squash of: * Doc typo * Ported some tun related functions. * Copy vnet.txt from linux to openbsd. * Simplified syz_emit_ethernet and stubbed out vnet.txt. * Undo clang-format header sorting: headers are order sensitive. * Uniquify tap devices by pid. * clang-format off for includes * Happier clang-format. * Partially revert "Uniquify tap devices by pid." Just rely on procid magic instead of getting it from a flag.

| | | | | | | 1. Extract consts on the latest linux tree. 2. Don't manually define O_TMPFILE/O_ACCMODE/_LINUX_CAPABILITY_VERSION_N, they are defined in kernel headers. 3. Don't use CLOCK_SGI_CYCLE as clock id, it's not implemented.

* sys/syz-extract: support missing arch headersDmitry Vyukov2018-10-282-5/+55
| | | | | | | | The latest Linux kernel misses some arch-specific headers on some archs: asm/a.out.h asm/prctl.h asm/mce.h Support that.
* sys/linux: floppy interface descriptionDenis Efremov2018-10-282-5/+85

* sys: check that target consts are definedDmitry Vyukov2018-10-191-2/+2
| | | | | | | | | | | | | | Currently when we get target consts with target.ConstMap["name"] during target initialization, we just get 0 for missing consts. This is error-prone as we can mis-type a const, or a const may be undefined only on some archs (as we have common unix code shared between several OSes). Check that all the consts are actually defined. The check detects several violations, to fix them: 1. move mremap to linux as it's only defined on linux 2. move S_IFMT to openbsd, as it's only defined and used on openbsd 3. define missing MAP_ANONYMOUS for freebsd and netbsd 4. fix extract for netbsd
* sys/linux: prohibit FAN_OPEN_PERM and FAN_ACCESS_PERMDmitry Vyukov2018-10-152-5/+6
| | | | | | | FAN_OPEN_PERM and FAN_ACCESS_PERM require the program to reply to open requests. If that does not happen, the program will hang in an unkillable state forever. See the following bug for details: https://groups.google.com/d/msg/syzkaller-bugs/pD-vbqJu6U0/kGH30p3lBgAJ
* Android: Fix sandbox implementationZach Riggle2018-10-122-3/+10
| | | | | | | | | | | My test harness for this code performed some steps that are not performed when syz-executor is invoked directy. Specifcally, we need to operate from a directory under /data/data, and have the correct UID/GID set as the owner of the directory. My test harness now correctly sets these, all sandbox operations succeed, and loop() is invoked.
* executor: Fuchsia: Use zx_task_resume_from_exception()Scott Graham2018-10-101-2/+2
| | | | | zx_task_resume() is deprecated; switch to using zx_task_resume_from_exception() instead.
* executor: tune memcg container logicDmitry Vyukov2018-10-101-15/+14
| | | | | | | | | | | | The current memcg container seems to lead to lots of hangs/stalls. Presumably the problem is with oom_score_adj and KASAN. Executor process tree eats all memory and then the leaf process is killed but the memory is not returned to memcg due to KASAN quarantine; and the parent processes are protected from killing with oom_score_adj=-1000. As the result the kernel locks up. 1. Don't use oom_score_adj=-1000. Instead bump leaf process score to 1000 (kill always). 2. Increase size of memcg to be larger than expected KASAN quarantine size.

* executor: make the debug output useful for race condition debuggingAlexander Popov2018-09-243-30/+39
| | | | | | | | | | | | | | | Sometimes race conditions are reproduced by syz-execprog and are not reproduced by the programs generated with syz-prog2c. In such cases it's very helpful to know when exactly the fuzzing syscalls are executed. Unfortunately, adding timestamps to the output of the original 'debug' mode doesn't work. This mode provides very verbose output, which slows down executor and breaks the repro. So let's make the executor debug output less verbose and add the timestamps.
