to reflect the new license.
We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.
Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.

Add SIOCSETHERCAP.
Add commented out NVMM (NetBSD Virtual Machine Monitor) operations
as this interface is still WIP and a subject to change.
llvm-svn: 350107
Summary:
Add new interceptors for a set of functions to reposition a stream:
fgetpos, fseek, fseeko, fsetpos, ftell, ftello, rewind .
Add a dedicated test.
Enable this interface on NetBSD.

NetBSD 8.99.26 changed the layout of internal structure
returned by dlopen(3), switch to it.
Set new values for amd64 and i386 based on the results
of &((struct Struct_Obj_Entry*)0)->linkmap.
llvm-svn: 348329
Summary:
fts(3) is API to traverse a file hierarchy.
Cover this interface with interceptors.
Add a test to validate the interface reading
the number of regular files in /etc.
Based on original work by Yang Zheng.

Eliminate dropped operations, add new operations.
Update included headers for newer need.
Add a fallback definition of nvlist_ref_t, becaue this type
is internal to libnpf and the kernel, not exported into public
headers.

PT_SET_SIGMASK and PT_GET_SIGMASK will be removed from NetBSD
without backward compat (it shortlived in a development branch).

Summary:
Introduce handling of 1200 NetBSD specific ioctl(2) calls.
Over 100 operations are disabled as unavailable or conflicting
with the existing ones (the same operation number).
Add a script that generates the rules to detect ioctls on NetBSD.
The generate_netbsd_ioctls.awk script has been written
in NetBSD awk(1) (patched nawk) and is compatible with gawk.
Generate lib/sanitizer_common/sanitizer_interceptors_ioctl_netbsd.inc
with the awk(1) script.
Update sanitizer_platform_limits_netbsd accordingly to add the needed
definitions.

Summary:
itimerval can contain padding that may be legitimately uninitialized.
On NetBSD there are four integers of type "long, int, long, int", the
int argument stands for __sanitizer_suseconds_t. Compiler adds extra
padding in this layout.
Check every field of struct itimerval separately.
Define __sanitizer_suseconds_t as long on FreeBSD, Linux and SmartOS,
and int on NetBSD. Define __sanitizer_timeval and __sanitizer_itimerval.

llvm-svn: 322399
Summary:
Changes:
- Don't attempt to intercept GLIBC specific functions like __strtol_internal.
This is required to stop intercepting it as we leak dlerror(3) for dlsym(3)
that cannot manage to find a symbol.
- Correct interception of fstatat(2).
- Don't run a test for fgetgrent_r() that is missing on NetBSD.
- Correct link_map location (offset) in Obj_Entry on x86_64 and i386.
- Stop intercepting getpshared-like functions in pthread(3). This is feature
is not enabled by default on NetBSD as it's unfinished.
- Switch intercepting from UTMP to UTMPX functions.

Summary:
NetBSD renames symbols for historical and compat reasons.
Add required symbol renames in sanitizer_common_interceptors.inc:
- gettimeofday -> __gettimeofday50
- getrusage -> __getrusage50
- shmctl -> __shmctl50
Additionally handle sigaction symbol mangling.
Rename the function symbol in the file to SIGACTION_SYMNAME and define
it as __sigaction14 for NetBSD and sigaction for !NetBSD. We cannot use
simple renaming with the proprocessor, as there are valid fields named
sigaction and they must be left intact.

Summary:
The pthread_once(3)/NetBSD type is built with the following structure:
struct __pthread_once_st {
pthread_mutex_t pto_mutex;
int pto_done;
};
Set the pto_done position as shifted by __sanitizer::pthread_mutex_t_sz
from the beginning of the pthread_once struct.
This corrects deadlocks when the pthread_once(3) function
is used.

Summary:
Changes:
* Add initial msan stub support.
* Handle NetBSD specific pthread_setname_np(3).
* NetBSD supports __attribute__((tls_model("initial-exec"))),
define it in SANITIZER_TLS_INITIAL_EXEC_ATTRIBUTE.
* Add ReExec() specific bits for NetBSD.
* Simplify code and add syscall64 and syscall_ptr for !NetBSD.
* Correct bunch of syscall wrappers for NetBSD.
* Disable test/tsan/map32bit on NetBSD as not applicable.
* Port test/tsan/strerror_r to a POSIX-compliant OSes.
* Disable __libc_stack_end on NetBSD.
* Disable ReadNullSepFileToArray() on NetBSD.
* Define struct_ElfW_Phdr_sz, detected missing symbol by msan.
* Change type of __sanitizer_FILE from void to char. This helps
to reuse this type as an array. Long term it will be properly
implemented along with SANITIZER_HAS_STRUCT_FILE setting to 1.
* Add initial NetBSD support in lib/tsan/go/buildgo.sh.
* Correct referencing stdout and stderr in tsan_interceptors.cc
on NetBSD.
* Document NetBSD x86_64 specific virtual memory layout in
tsan_platform.h.
* Port tests/rtl/tsan_test_util_posix.cc to NetBSD.
* Enable NetBSD tests in test/msan/lit.cfg.
* Enable NetBSD tests in test/tsan/lit.cfg.
