[uml-devel] openswan @ missing symbols strstr & memset

[Nikola Ciprich]

Hello, I was trying to get openswan working under UML, module compiles
fine, but trying to load it fails with complaint about unresolved symbol
memset and strstr
I've found that those symbols are exported in i386 ksyms, but not in uml
ksyms, so I've created little patch (enclosed), and everythink seems to
work well. I'd like to ask, if my solution is 'clean' and if yes,
wouldn;t it be usefull to add all such missing symbols (for work wish
strings etc). if yes, i'd gladly create patch for inclusion
thanks

Yes, it is clean (just it should go inside user_syms.c), but IIRC it has been 
applied to late 2.4 & 2.6 UML kernels (I could be wrong). Check against 
latest version and if it is not there (look inside user_syms.c) send the 
patch, after making the change in user_syms.c, to Jeff Dike.

Re: [uml-devel] openswan @ missing symbols strstr & memset

[Nikola Ciprich]

thanks for reply, I took a look to user_syms.c of version I'm using, and
really both memset and strstr are exported, but with
EXPORT_SYMBOL_PROTO. whats the difference between EXPORT_SYMBOL and
EXPORT_SYMBOL_PROTO? and it did not work, so should I just remove
_PROTO?
thanks in advance
