New Revision: 214334
URL: http://svn.freebsd.org/changeset/base/214334
Log:
Get cpuset in pthread_attr_get_np() and free it in pthread_attr_destroy().
MFC after: 7 days
After this change firefox 4.0b8pre built from mozilla trunk crashes with
SIGBUS while starting, on /h...@r214363m amd64. It may be related to
$ js
Assertion failure: stackBase, at jsnativestack.cpp:217
and the calls preceding it
pthread_attr_get_np(thread, &sattr);
pthread_attr_getstack(&sattr, &stackBase, &stackSize);
java/openjdk6 doesn't start, too
$ java
#
# A fatal error has been detected by the Java Runtime Environment:
#
# Internal Error (os_bsd_x86.cpp:876), pid=10495, tid=34389128704
# Error: pthread_attr_get_np failed with err = 34
It is difficult to know which cpuset size kernel is using,
for example, cpuset_getaffinity has following code:
if (uap->cpusetsize < sizeof(cpuset_t) ||
uap->cpusetsize > CPU_MAXSIZE / NBBY)
return (ERANGE);
So if I provide a buffer, who can tell me what size I should use?
too large or too small ? where can I get the size ?
