domains flapping
Whilst tinkering with lvm (which now works great - thanks!), I made a typo which caused the domain to stop booting. I think it was just that I got the config file wrong in terms of which device mapped to which. Anyway, I had specified ''restart=True'' and so the domain was starting to boot, failing, then restarting again. This was the expected behaviour, but it was a pain to kill.

[cfe-dev] RFC: Replacing the default CRT allocator on Windows

Dovecot and MariaDB/MySQL
...along with the account and used when validating the password. That way in the event of a SQL injection attack that dumps the database - yes it is still bad, but 20 accounts that have the same password will have radically different hashes and thus won't be a clue that they are the same, the blackhat that gets the database dump would have to generate a rainbow table for each unique salt. I've looked at at least a dozen different Dovecot / MariaDB howto guides and none of the ones I have looked at supported any kind of individual salting of the user passwords. Can someone point me to a...

RFC: Replacing the default CRT allocator on Windows
Hello, I was wondering how folks were feeling about replacing the default Windows CRT allocator in Clang, LLD and other LLVM tools possibly. The CRT heap allocator on Windows doesn't scale well on large core count machines. Any multi-threaded workload in LLVM that allocates often is impacted by this. As a result, link times with ThinLTO are extremely slow on Windows. We're observing

curl build system is broken and so is mock
...on't link against those features (except it will for libssl.so.10 if ANY tls option is chosen) but the binary will link against the libraries if it is there. EVEN IF THE DEVEL PACKAGE WITH HEADER FILES IS NOT PRESENT. There is something very broken about how curl builds. If I was a skilled blackhat, I might look for ways that causes it to be exploitable, because the building of curl doesn't do what the user expects. I tried building curl creating a mock build environment where openssl is forbidden. There's a bug in mock. In both base and updates I have exclude=openssl* I had to...

Revised OpenSSH Security Advisory

This would have highlighted that as the problem area. e. We believed very strongly that the issue was unknown in the Blackhat community at the time. We also made the decision based on the subtlety of the problem.

How insecure is NIS ? Possible alternatives ?
Hi, In the past I've setup simple centralized authentication with NIS and NFS, without bothering about possible security implications. Over the next month I have to setup a new network in a local school, and I wonder if I should use NIS/NFS. I still have my own documentation, it's simple and somewhat bone-headed to setup, and it just works. RHEL/CentOS 7 still provide NIS, and I vaguely

dictonary attacks
Hi hoping someone can help me a little with this one. I have 2 mail servers, the incoming mail server runs dovecot and the outgoing mail server runs postfix with sasl. Lately I noticed a lot of spammers are running dictionary attacks on my incoming server and then using that user/password for sasl on the outgoing server. The weird thing is I never see on the logs the guessed

[PATCH v5 00/12] Enable GPU switching on pre-retina MacBook Pro
Enable GPU switching on the pre-retina MacBook Pro (2008 - 2013), v5. The main obstacle on these machines is that the panel mode in VBIOS is bogus. Fortunately gmux can switch DDC independently from the display, thereby allowing the inactive GPU to probe the panel's EDID. In short, vga_switcheroo and apple-gmux are amended with hooks to switch DDC, DRM core is amended with a
