1999-10-25Patch from Eric Norum <eric@cls.usask.ca> to address the following problemJoel Sherrill2-2/+2
report from Philip A. Prindeville <philipp@zembu.com>: I was working on a device driver for a certain ethernet chipset that occassionally wraps in its buffer, and causes a resulting mbuf chain with only a few dozen bytes in the first mbuf of the chain. I wouldn't have thought this would be a problem, until I ran some stress tests that flooded the ethernet receiver with packets and started to get panics here: 250 251 if (m->m_pkthdr.len < sizeof(struct ip)) 252 goto tooshort; 253 254 #ifdef DIAGNOSTIC 255 if (m->m_len < sizeof(struct ip)) 256 panic("ipintr mbuf too short"); 257 #endif 258 259 if (m->m_len < sizeof (struct ip) && 260 (m = m_pullup(m, sizeof (struct ip))) == 0) { 261 ipstat.ips_toosmall++; 262 return; 263 } 264 ip = mtod(m, struct ip *); and the panic was at line 256. But if I #undef'd DIAGNOSTICS, then the m_pullup() at line 260 does the right thing and the packet ends up being processed just fine. So I started wondering, (a) why was the test checking for something that apparently wasn't a fatal condition but rather one that is subsequently recovered from a couple of lines later and (b) why panic as a diagnostic "aid" from a recoverable condition rather than just (say) log a message to the console? All of this seems overly severe for no reason that is readily apparent to me.
1999-10-25Patch from Charles-Antoine Gauthier <charles.gauthier@iit.nrc.ca>Joel Sherrill1-0/+8
to initialize the pthread cancellation fields. This is a patch to _POSIX_Threads_Create_extension that fixes the problem.

1999-10-11Moved RTEMS error and association from libmisc to libc support toJoel Sherrill7-13/+13
avoid cyclic dependencies generated when moving packages to the top level.
1999-10-11Removed targets and configurations that are no longer functionalJoel Sherrill14-1428/+0
and not likely to become so. Comments on each configuration are below. + Force CPU386 - This BSP was developed as part of the initial port of RTEMS to the i386. This board has been unavailable for a long time now. + GO32 - This BSP and some CPU code supported djgpp v1.x. This version is now quite old. No one has stepped forward to update the code to v2.x which may be technically impossible anyway. More importantly, go32 has been superceded by the pc386 BSP.
1999-10-11Added as part of moving librdbg to its own top level package. This wasJoel Sherrill6-0/+141

1999-10-06Modified to avoid conflicts on definitions of malloc. newlib 1.8.2Joel Sherrill7-7/+7
now prototypes the malloc family in stdlib.h. This causes conflicts with the way the network stack overrides the definitions of malloc. As best I (being Joel) can tell, commenting stdlib.h out keeps the files compiling and referencing the desired malloc/free but results in more warnings.
