'RELENG_5_2_1_RELEASE'. This commit was manufactured to restore the state of the 5.2.1-RELEASE image. Releases prior to 5.3-RELEASE are omitting the secure/ and crypto/ subdirs.

For the amd64 we need to do some extra stack alignment fixups. Otherwise

we can end up with some threads with a non-16-byte-aligned stack. This causes some interesting side effects, including general protection faults leading to a SIGBUS when doing floating point or varargs. This should be just a verbose NOP for the other platforms. Approved by: re (scottl)

Fixed another bug in the threaded close() call; clear the

stale stdio descriptors flags. PR: bin/51535 Submitted by: Enache Adrian Reviewed by: deischen Approved by: re (scottl)

If an application closes one of its stdio descriptors (0..2),

2003-05-31T05:20:44Z

an excessive close() on one of these descriptors would cause a memory for this descriptor to be allocated in the internal descriptor table. When this descriptor gets used again, e.g. through the call to open() or socket(), the descriptor would be erroneously left in the blocking mode, and the whole application would get stuck on a blocking operation, e.g., in accept(2). Prevent this bug from happening by disallowing close() against non-active descriptors (return -1 and set errno to EBADF in this case). Reviewed by: deischen Approved by: re (scottl)
