| |
We use Linux 2.1.x for software development where Linux workstations NFS mount filesystems on a Sun UltraSparc server. The Ultra runs SunOs 5.5.1.
We ran 2.1.84 with no problems. We recently upgraded our build environment to 2.1.102. (We've been using 2.1.102 in application testing for a couple of months so we decided it was stable enough to use for compiling and linking too).
Immediately after upgrading, we noticed that our executable files were corrupted during the link phase of a build. Remember that the objects and the executable are all stored on the UltraSparc server. If we link under Linux 2.1.84 then there is no corruption and if it is 2.1.102 then there IS corruption.
====> I've repeated this with 2.1.115 so the bug is still alive ====> in the latest edition of the kernel. This is a very puzzling bug. We do NOT see corruption when we link directly to the local hard drive and we don't see corruption when we NFS mount another 2.1.102 Linux box and link on its file system.
The only corruption occurs when running 'ld' under 2.1.102 (or 2.1.115) and writing the executable to a SunOS 5.5.1 NFS server. (BTW, we using GNU ld version 2.8.1 (with BFD linux-2.8.1.0.1)).
I can spend some time helping with a 'remote debug' of this problem if there are tools, logs, debug switches, etc, that can be thrown to gather data here. I also have a set of objects which I can probably ship to a Linux developer to reproduce this bug. He/she just needs a SunOS box handy. Alternatively, the NFS/TCP/UDP developer's can try to track the source differences between 2.1.84 and 2.1.102.
IMHO, its a serious problem which needs attention.
