LIST OF KNOWN BUGS IN AM-UTILS OR OPERATING SYSTEMS
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
(1) mips-sgi-irix*
|
|
|
|
|
|
|
|
|
|
[1A] known to have flakey NFS V.3 and TCP. Amd tends to hang or spin
|
|
|
|
|
infinitely after a few hours or days of use. Users must install recommended
|
|
|
|
|
patches from vendor. Patches help, but not all the time. Otherwise avoid
|
|
|
|
|
using NFS V.3 and TCP on these systems, by setting
|
|
|
|
|
|
|
|
|
|
/defaults opts:=vers=2,proto=udp
|
|
|
|
|
|
|
|
|
|
[1B] yp_all() leaks a file descriptor. Eventually amd runs out of file
|
|
|
|
|
descriptors and hangs. Am-utils circumvents this by using its own version
|
|
|
|
|
of yp_all which uses udp and iterats over NIS maps. The latter isn't as
|
|
|
|
|
reliable as yp_all() which uses TCP, but it is better than hanging.

|
(2) alpha-unknown-linux-gnu (RedHat Linux 4.2)
|
|
|
|
|
|
|
|
|
|
hasmntopt(mnt, opt) can goes into an infinite loop if opt is any substring
|
|
|
|
|
of mnt->mnt_opts. Redhat 5.0 does not have this libc bug. Here is an
|
|
|
|
|
example program:
|
|
|
|
|
|
|
|
|
|
#include <stdio.h>
|
|
|
|
|
#include <mntent.h>
|
|
|
|
|
main()
|
|
|
|
|
{
|
|
|
|
|
struct mntent mnt;
|
|
|
|
|
char *cp;
|
|
|
|
|
mnt.mnt_opts = "intr,rw,port=1023,timeo=8,foo=br,retrans=110,indirect,map=/usr/local/AMD/etc/amd.proj,boo";
|
|
|
|
|
cp = hasmntopt(&mnt, "ro");
|
|
|
|
|
printf("cp = %s\n", cp);
|
|
|
|
|
exit(0);

[3A] At least the gcc 2.7.0 fixincludes-mangled <sys/utsname.h> needs a

|
|
|
[4A] "Randall S. Winchester" <rsw@Glue.umd.edu> reports that for amd to
|
|
|
|
|
start, you need to kill and restart rpc.mountd and possibly also make sure
|
|
|
|
|
that nfsd is running. Normally these are not required.

[4B] "Stefan Vogel" <vogel@physik.unizh.ch> reports that if your amq

|

executable dump core unexpectedly, then it may be a bug in gcc 2.7.x.
|
|
|
|
|
Upgrade to gcc 2.8.x or use IBM's xlC compiler.

[C] Do not link amd with libnsl. It is buggy and causes amd to core dump
|
|
|
|
|
in strlen inside strdup inside svc_register().

(5) *-linux-gnu (RedHat Linux 5.1)
|
|
|
|
|
|
|
|
|
|
There's a UDP file descriptor leak in libnsl in RedHat Linux 5.1. This
|
|
|
|
|
library part of glibc2. Am-utils currently declares redhat 5.1 systems as
|
|
|
|
|
having a "broken yp_all" and using an internal, slower, leak-free version.
|
|
|
|
|
The leak is known to the glibc maintainers and a fix from them is due soon,
|
|
|
|
|
but it is not yet in the glibc-2.0.7-19 RPM.

(6) rs6000-ibm-aix4.1.x
|
|
|
|
|
|
|
|
|
|
A bug in libc results in an amq binary that doesn't work; amq -v dumps core
|
|
|
|
|
in xdr_string. There is no known fix (source code or vendor patch) at this
|
|
|
|
|
time. (Please let amd-dev know if you know of a fix.)
