5756 - Assertion failure in the sockopt test

Status: RESOLVED INVALID

(NSPR :: NSPR, defect, P3)

Description

[Wan-Teh Chang]

The OS is Red Hat Linux 5.2 (kernel 2.0.36, glibc 2.0).
The test machine is dewey.mcom.com.  The NSPR release
is 3.1.1.

When running the sockopt test, debug build, I get this
assertion failure:
Assertion failure: (-1 == rv) || (sizeof(ttl) == length), at ptio.c:2498

The value of 'rv' is 0, and the value of 'length' is 4.
Since 'ttl' is PRUint8, sizeof(ttl) is 1.

This appears to be a bug in glibc 2.0.  Before we call
getsockopt, we set 'length' to 1 (the size of 'ttl').
On return, getsockopt sets 'length' to 4, larger than
what we allocated.

This problem doesn't show up on the currently supported Linux platform, with 2.2
kernel and glibc 2.x (> 2.0). This should be closed as invalid.
