Mathieu Desnoyers	[RFC patch 07/27] Text Edit Lock - Architecture Independent ... This is an architecture independant synchronization around kernel text modifications through use of a global mutex. A mutex has been chosen so that kprobes, the main user of this, can sleep during memory allocation between the memory read of the instructions it must replace and the memory write of the breakpoint. Other user of this interface: immediate values. Paravirt and alternatives are always done when SMP is inactive, so there is no need to use locks. Signed-off-by: Mathieu Desnoyers &l...

It's ok to modify an instruction non-atomically (multiple memory accesses to a large and/or non aligned instruction) if and only if we have inserted a breakpoint at the beginning of the instruction.

Mathieu Desnoyers	[RFC patch 26/27] Immediate Values - Jump Adds a new imv_cond() macro to declare a byte read that is meant to be embedded in unlikely(imv_cond(var)), so the kernel can dynamically detect patterns such as mov, test, jne or mov, test, je and patch it with nops and a jump.

Mathieu Desnoyers	[RFC patch 00/27] Jump-based NMI-safe immediate values and m... Hi Ingo, Here is the patchset you requested. I did not port the marker reintegration to your sched-devel tree though, because many changes happened since you have done the original work. It applies on top of sched-devel.git latest. You will notice that I implemented what we discussed yesterday : using nops and jump for the heavily optimized version of markers. Comments are welcome. Running this with my ~120 LTTng markers on x86_32 detects 97% of the sites. 4 out of 120 did had to fall back on ... [ message continues ]	Apr 16, 5:34 pm 2008

Jesper Juhl	[PATCH][netlabel] Don't risk NULL ptr deref in netlbl_unlabe... Hi, dev_get_by_index() may return NULL if nothing is found. In net/netlabel/netlabel_unlabeled.c::netlbl_unlabel_staticlist_gen() the function is called, but the return value is never checked. If it returns NULL then we'll deref a NULL pointer on the very next line. I checked the callers, and I don't think this can actually happen today, but code changes over time and in the future it might happen and it does no harm to be defensive and check for the failure, so that if/when it happens we'll...

Paul Moore	Re: [PATCH][netlabel] Don't risk NULL ptr deref in netlbl_un... I agree we should check for NULL here. I checked the return of dev_get_by_index() in the rest of the file I must have just forgotten to check it here.
