* executor: change syscall argument type to intptr_tmunjinoo2019-05-071-1/+1
| | | | | The type size of long depends on compiler. Therefore, changing to intptr_t makes it depends on architecture.
* pkg/host: enable FeatureComparisons on OpenBSDAnton Lindqvist2019-01-211-12/+2

* all: support extra coverageAndrey Konovalov2019-01-161-2/+2
| | | | | | | | | | | | | | | Right now syzkaller only supports coverage collected from the threads that execute syscalls. However some useful things happen in background threads, and it would be nice to collect coverage from those threads as well. This change adds extra coverage support to syzkaller. This coverage is not associated with a particular syscall, but rather with the whole program. Executor passes extra coverage over the same ipc mechanism to syz-fuzzer with syscall number set to -1. syz-fuzzer then passes this coverage to syz-manager with the call name "extra". This change requires the following kcov patch: https://github.com/xairy/linux/pull/2
* executor: update KCOV support for FreeBSDMichael Tuexen2019-01-141-17/+4
| | | | | | KCOV support has been added to FreeBSD in r342962. Use the header file and update the code to latest changes introduced in the review process.
* executor: adapt os_init() to NetBSD with PaX MPROTECTKamil Rytarowski2019-01-091-0/+3
| | | | | | Initialize syz data segment with protection allowed by PaX MPROTECT. PROT_MPROTECT() registers future potential protection that is allowed to be enabled in future.
* executor: Fix FreeBSD such all platforms use same number of entriesMichael Tuexen2018-12-291-1/+2
| | | | | | | FreeBSD sets the kcov buffer as number of bytes instead of number of entries. This also fixes the mmap() call, which was failing due to inconsistent sizes. The failing was hidden due to wrong error handling.
* executor: fix error handling of mmap()Michael Tuexen2018-12-291-6/+5
| | | | | mmap() returns MAP_FAILED, which is (void *)(-1), in case of an error. This is different from NULL.

* executor: improve kcov compatibility with upcoming supportMichael Tuexen2018-12-281-3/+8
| | | | | Get ioctl() definitions and usage in sync with the upcoming support reviewed in https://reviews.freebsd.org/D14599.
* executor: KIOENABLE accepts a mode argument on OpenBSDAnton Lindqvist2018-12-281-5/+3
|
* executor: include sys/kcov.h on OpenBSDAnton Lindqvist2018-12-271-3/+6
| | | | Since we no longer cross-compile, there's no need to repeat the defines.
* executor: move setrlimit from setup_control_pipes to bsd os_initDmitry Vyukov2018-12-141-0/+5
| | | | This broke fuchsia build. We need setrlimit only for bsd.
* executor: reapply setuid sandbox for bsdGreg Steuck2018-12-111-19/+0
| | | | | | | | | | * Revert "Revert "executor: add setuid sandbox for openbsd"" The problem is the low file descriptor limit. This reverts commit 4093e33b1338f274ae0062f555de9d6af8640d61. * executor/executor make sure the file descriptor limit is sufficient
* Revert "executor: add setuid sandbox for openbsd"Greg Steuck2018-12-101-0/+19

* executor: add setuid sandbox for openbsdGreg Steuck2018-12-101-19/+0
| | | | | | | | | | * executor/common_bsd: add setuid sandbox Fixes #833 cc @mptre * Reduced duplications, resolved TODO.

* executor: OpenBSD does not allow write and exec mappings by defaultAnton Lindqvist2018-08-311-1/+8
| | | | | | | | | | Since the OpenBSD target does not make use of syz_execute_func yet, just drop PROT_EXEC for now. Supporting write and exec would require one to edit /etc/fstab during installation. Regression introduced in commit a4718693 ("sys/linux: add syz_execute_func").
* sys/linux: add syz_execute_funcDmitry Vyukov2018-08-301-1/+1
| | | | | | The function executes random code. Update #310
* Add mandatory OpenBSD bits (#689)Anton Lindqvist2018-08-281-2/+26

* executor: remap cover fd's to higher valuesDmitry Vyukov2018-08-081-2/+5
| | | | | | Remap cover fd's to 24x range to prevent interference with fd's used during fuzzing and also to make fd number consistent with/without cover enabled.
* executor: overhaulDmitry Vyukov2018-07-241-0/+104
Make as much code as possible shared between all OSes. In particular main is now common across all OSes. Make more code shared between executor and csource (in particular, loop function and threaded execution logic). Also make loop and threaded logic shared across all OSes. Make more posix/unix code shared across OSes (e.g. signal handling, pthread creation, etc). Plus other changes along similar lines. Also support test OS in executor (based on portable posix) and add 4 arches that cover all execution modes (fork server/no fork server, shmem/no shmem). This change paves way for testing of executor code and allows to preserve consistency across OSes and executor/csource.
