Status Meeting (April 2014)

by Aleksey Bragin

Hello, Let me invite you to the monthly status meeting taking place last Thursday of this month, 24th of April, 19:00 UTC. And this date is very close to now! IRC service will only be started shortly before the meeting. Your participation passwords and server address will be emailed to you shortly before the meeting starts, and they are going to be different once again as they are not stored in any database. Hopefully it's not much of inconvenience. If someone still is not getting passwords sent before a meeting - please email Pierre before the meeting started to get one. Please send agenda proposals to me before the meeting, so that we can start with a proposed agenda. Regards, Aleksey Bragin

Using TerminateThread like this feels icky.

Heartbleed issue on the ReactOS infrastructure

by Pierre Schweitzer

Dear all, In case you don't use SSL/TLS on our infrastructure (web sites - drupal, jira, fisheye), skip reading (and reconsider your choices about such non-usage). As you may (should?) have heard recently, OpenSSL has suffered a critical security vulnerability (CVE-2014-0160), known as Heartbleed Bug (http://heartbleed.com/). Most of our services were using an affected release of OpenSSL, with heartbeat feature activated. Be it, mails services, web services (Drupal, Jira). We reacted quickly passed the public announcement, and the availability of the fix to apply it on our infrastructure to limit the risks. Anyway, this might have been enough (actually, the issue has been here for two years!) to allow potentials attackers to, for instance, steal our SSL private keys. So, we took the decision to renew all our certificates and private keys to guarantee safe infrastructure usage. Due to the nature of the security issue, we don't know what may have been compromised in the infrastructure and in the user database. Hence our drastic measures. What does it mean for you? It means that your account information (username + password) might have been compromised, and your account itself could have been compromised (cookie stealth with the attack). We highly recommend you to change your passwords and check that everything is fine on your account. I shall remind you that password change can take up to 6h to propagate to Fisheye & Jira. As a side note, we enabled a while ago Perfect Forward Secrecy on our infrastructure that should ensure that even if our private keys leaked, your past communications (so, login on the infrastructure, for instance) can't be deciphered. Unless your session ticket leaked as well... We are really sorry for the caused inconvenience. I'm available by email or on IRC to answer your questions and clear your doubts. With my best regards, -- Pierre Schweitzer<pierre at reactos.org> System Administrator ReactOS Foundation

Short announce: My Serial port-on-MMIO implementation works - allowing debug logging on laptops

by Minas Abrahamyan

Hi all, With this few words I would like to share the joyous event of MMIO-based serial port implementation has finally worked for me. This is the equivalent of earlycon serial port implementation in Linux with some extension (so now it is even better then Linux one) Some work yet is needed to be done to transform the work into the normal patch, but the good news is it is working, and still doesn't require PNPmanager for work, i.e. it starts very early in kernel and writes kernel log messages. I use ExpressCard 34 extension board Serial RS232 port, on laptop, but think it will work fro PC Cards too (former name PCMCIA). ==Importance: Touching the hardware== For the more developers we need more working PC models ( Real Hardware) Almost all modern PCs are laptops with PCIe bus (the rest are desktops) (but few of them able to boot the ReactOS) Modern serial ports are recommended to use /often use MMIO-based data transfer instead of former I/O ports. So now possibility appears to debug these new computers and force the ReactOS to work on this important part of new PCs. Thanks for attention -Minas Abrahamyan PS Curious note: for catching the debug logs I use the (small and cheap) soap box-sized microcontroller board with LCD (ready-unit), and I call it "ReactOS debug logger" appliance. It doesn't take space and doesn't produce any noise

Re: [ros-dev] [ros-diffs] [pschweitzer] 62675: [CHARMAP] Use rather wcsncpy(). A bit less safe, but at least, data are copied till possible

by Timo Kreuzer

I don't really see the reason here. Whether using the secure function or not is is a question of whether we need null-termination or not. If we need it the secure function will do the right thing. If we do not need null-termination the non-secure function does the right thing and the secure function would not add any security, but simply do the wrong thing. MSDN says about the lfFaceName member of the LOGFONT structure "A null-terminated string that specifies the typeface name of the font. " So we want it to be null-terminated and adding one more character does not add anything useful, but will result in a broken structure. Another difference is that the non-secure function pads the destination array with nulls, the secure function does - afaik - not. If that is the reason, I'd prefer zeroing it out before copying the string.
