Re: Re: Bug#888263: Spectre : release kernel 4.9.77 to stretch before p-u
Hi, I guess the kernel will be rebuilt due to the ARM64 breakage but I confirm it works fine on the following machines : Intel Core i7 4790 w/ GeForce GTX 1070 and NVidia BLOB 384.111 Intel Core i7 4800 MQ Intel Pentium N3700 AMD Phenom x4 9840 w/ GeForce GTX 970 and NVidia BLOB 384.111 However it seems that the updated kernel does not fix against variant 1 and 2 of Spectre. :'( Rgds

Retpoline is included in the kernel but there is not gcc support yet. And IBRS/IBPB is not there yet, nor the microcodes updates.

I'm not totally sure how to interpret: 2018/02/02 - [12:40:22] (bwh): Corsac: Sorry, no, why don't you go ahead anyway Is it go for upload, even without review? If so, I'll do the 4.9.80 upload tonight and watch the list for any bug from stretch-pu. Regards, -- Yves-Alexis signature.asc Description: This is a digitally signed message part

Oh, I misunderstood what you were saying. No I don't.

Yes I think it'd be a good idea to let this one stay a bit longer in s-p-u. Do I need to ping someone before doing the upload?

This makes sense. I think once an updated gcc is available in stretch we should bump the ABI number and Build-Depends at the same time as un- reverting that. > I'm currently running a full build in pbuilder in a stretch chroot, so it > should be ready for upload if it's ok for you. > > I'm unsure about stable-uploads procedure for the kernel (SRM and debian-boot > notifications for example) so pointer to any specific stuff would be welcome. I've tended to upload shortly before point releases, but I think we should really be uploading earlier and more often so regressions are more lilely to be caught before a point release.

Hi Ben, So I went ahead an updated to 4.9.78 and added the revert for the VERMAGIC stuff (which is queued for 4.9.79). I'm currently running a full build in pbuilder in a stretch chroot, so it should be ready for upload if it's ok for you. I'm unsure about stable-uploads procedure for the kernel (SRM and debian-boot notifications for example) so pointer to any specific stuff would be welcome.
