[...] However, on 64-bit the long format of ldd has a 16-bit signed immediate offset (0xffff), meaning it can reach +0x7fff e.g. 4095 GOT slots. Do you have the time to test something out? * Make this conditional on 32-bit vs. 64-bit and allow for 4095 GOT entries on 64-bit. * Fix ELF_GOT_STUB for the 64-bit case. It needs to reassemble a 16-bit offset, the current code is IMO incorrect. i.e. it should be "& 0x7fff", and use a new reassemble_16 see the PA 2.0 book definition of ldd. * Build kernel. * Test loading NFS moudle.
Carlos, thanks a lot for those explanations (and keep up your work with NPTL :-)). I'll know what you mean, and if it works it's a good idea. I'll try to come up with a patch. A few notes: - the GOT table is only used for 64bit anyway, so no need to differentiate for 32/64bits - Another possibility could be to sort the tables, so to reduce the number of needed entries.
