It's initialized to something that's not necessarily 64 characters, so (I assume) the size specification is there to reserve the appropriate amount of space, which is precisely 64 bytes. > OSK0 + OSK1 is 64, why need an extra byte?

Since this is just about getting OS X to keep working, I figured I'd keep changes to a minimum. Reworking key initialization, adding write support, etc. could (should?) be part of a separate series, if we decide we want a more realistically emulated AppleSMC. In that case, minimizing churn and leaving things as-is in this particular case would be preferable. Let me know what you think.

Since 'default_osk' is used read-only, it could be 'const' but since it is assigned as `s->osk = default_osk` which is a PROP_STRING it can not be const. For this read-only reason I think it is safer to let the cpp calculate the size to allocate to this buffer (without specifying 64 which lead to confusion). > >> OSK0 + OSK1 is 64, why need an extra byte? > > Right, I undid that part of the patch, will resubmit everything minus > that hunk as part of v2. > >> Can yoy add some self-explanatory #define and use them later in this file: >> >> applesmc_add_key(s, "OSK0", 32, s->osk); >> applesmc_add_key(s, "OSK1", 32, s->osk + 32); >> >> and >> >> if (!s->osk || (strlen(s->osk) != 64)) { >> fprintf(stderr, "WARNING: Using AppleSMC with invalid key\n"); > > Do I have to, now that I'm staying away from touching that bit in the > first place ? :) > > The original patch Eric Shelton proposed (inspired by FakeSMC) > completely reworks how keys are initialized, adds write support (and > access permissions) for select keys, and generally implements a much > more complete emulation of the AppleSMC.
