Hi, Ubuntu has a bug[1] which causes `uname -r` and the kernel version reported via `ossvermagic -z -s` to not match, making 'soundon' fail even when the same kernel is used for compiling the module and for loading it later.
The attached patch saves the version of the running kernel used during "sh
install.sh" in a new symbol ("__oss_link_vermagic") in osscore.ko (this is
included via "ubuntu_version_hack.inc"). It makes ossvermagic check for it if
'-u' switch is used, which happens only if "soundon" can't get a match in
regular way. I don't think this should break anything, unless a rather twisted
Linux system exists where /lib/modules/`uname -r`/build is linked to a
different kernel version than the one `uname -r` indicates...
The patch also includes some unrelated misc. changes:
A. cmd/ossxmix/ossxmix.c - call gdk_notify_startup_complete at cleanup(),
so that if startup failed notification won't stay stuck up until the DE decides
to remove it.
B. configure - unset CDPATH, to avoid 'cd $SRCDIR && pwd' failing if it's
set. autoconf uses same trick, so this should work portably[2].
C. setup/Linux/oss/build/install.sh - call `uname -r` only once, and use
that value (same is done for soundon). Remove mentions of 'modules.inc.orig'
now that osscore_symbols.inc is used instead.
D. setup/Linux/oss/build/osscore.c - make strncpy, strcpy not increment s1
needlessly. Use correct return type for new_ioctl_t to avoid harmless warning.
E. setup/elflib.inc - use #ifdefs to avoid harmless 32/64 bit warning on
printing shdr[i].sh_offset. Allow list_symbols return something sane to avoid
always returning 0 from ELF_LOAD_SYMTAB, so that ossvermagic can avoid
unneccesary checks.
Yours,
Yair K.
