I've seen you released skas v8 meanwhile, but for 2.6.9 only. > If you have a 2.6.11-rc patch as well already that would be very nice. I've just done a -V7 for -rc3-bk6... I've called it -V7-rc1 because potentially something could go wrong (in general, and for this special kernel). I've also added three patches from the V8-rc1 for 2.6.9 (so it's actually a -V7a: versioning is fscking up). I've not yet added the SYSEMU_SINGLESTEP support, because it seemed me a bit unclean even in 2.6.9, so even porting it cleanly to 2.6.10 is a bit hard (C. Aker did the porting, and , but in that form it is not up-to-date with the introduction of the set/clear_singlestep accessors). The problem is that PTRACE_SYSEMU_SINGLESTEP is put together with PTRACE_SYSCALL, not with PTRACE_SINGLESTEP... I understand in 2.6.7 it maybe made sense (SINGLESTEP had a different behaviour then, problems when singlestepping syscalls) but it's unclean in 2.6.9 and does not port well to 2.6.10, as said (... unless I miss something, I'm going to cleanup this for 2.6.9 and for 2.6.10. For 2.6.7 I would rawly use your version, unless I discovered any bugs during the cleanup (backporting cleanups is useless IMHO, unless for other reasons like keeping things in sync). -- Paolo Giarrusso, aka Blaisorblade Linux registered user n. 292729 http://www.user-mode-linux.org/~blaisorblade ------------------------------------------------------- SF email is sponsored by - The IT Product Guide Read honest & candid reviews on hundreds of IT Products from real users.
