Russell Coker: Execmem and SE Linux
Eddy writes about problems getting the game oolite to run under SE Linux [1].
Strangely after I fixed the shared object issue with libffcall1 (as described in my previous post [2]) it appeared to work for me.
Eddy asked how to allow one application to create write and executable memory regions without allowing such access for all programs. This can be done, in the targeted policy the type unconfined_execmem_exec_t triggers a transtion to the domain unconfined_execmem_t which permits the execstack and execmem operations. For example if the program /usr/bin/foo needs such access then the command chcon -t unconfined_execmem_exec_t /usr/bin/foo will change the type and the next time the program is launched from an unconfined session (a user login session, cron job, or daemon which is not constrained) then the change will apply.

So I was looking over some setgid binaries last night, seeing if there were any obvious security bugs.

Somewhat unbelievably (to me at least) there is still wireless in my mother’s backyard and it has only gotten better and stronger. But let’s face it, writing in garden lounge chairs among the frogs, birds, sun, rain and wind are sub-optimum for thinking and writing, so I am always looking for good and, most especially, gratis wireless.
I was pretty psyched to find a new cafe, 
The English front players were the key of that though match. By dominating
the Australian players, particularly in a few key scrums and mauls, they
logically and brilliantly won that first 1/4th final.
Despite a non optimal Johnny Wilkinson in kick play (maybe the only question
for England in that game), England qualifies (12-10) while Australia will
probably regret a few lost balls by their rear lanes in 2nd half time.
Anyway, congratulations to both teams for this very intense first match of
our rugby marathon for this week-end.
Now, let's hoipe we'll have the same intensity tonight for the much awaited
New Zealand-France in Cardiff....and of course, I hope for another victory
for a northern hemisphere team.
A party calling themselves Oslo Byaksjon this year entered the elections, with the tagline “P parti med byen” (roughly, “On the city’s side”, or “With the city”).
Their platform wasn’t horrible, and I briefly entertained the notion of voting for them. In the end I didn’t, for some important reasons; but that’s not very relevant.
A Norwegian tradition is for the political parties to set up stands leading up to the election, along 
Is it a result of the physical demands of the job? Or is it that the type of job ( outdoors with lots of heavy lifting), attract the athletic types? Do they have to pass certain physical standards as to pilots? Was there always first class seats? Or did that come about when flying became cheaper? Are employees trained to deal with irate passengers? In what ways do pilots bitch about the long waits/delays they also have to endure? What can they do when they are waiting, as we did for an hour last night, during the massive traffic jams that are especially noxious in NYC-area airports? Do pilots have any say in the way airports are run? Why do they consistently provide less chairs than are needed in lounges, even in new terminals, as the one I was in tonight? Do air traffic controllers ever meet face-to-face with pilots or do they largely have a virtual relationship? Are programmers who patch, improve, and build traffic control systems housed in the airports, or elsewhere?
Airports are not only fascinating for technological and sociological reasons but I reckon there is a lot of interesting psychological work that must happen in airports. I imagine that during those long, endless waits in the lounge, on the security lines, on the tarmac, people must often take the time to reflect, on where am I going, where am I coming from, and not in the literal sense but the metaphorical one. I know that I have spent many hours in airports letting my mind wander to places and thoughts in ways that don’t happen as easily or often elsewhere. And in many instances, I don’t think that this propensity to indulge in some reflective thinking, is a matter of time, that is waiting. For me at least, it is the fact that many times when I fly, I am moving between worlds.
While I have flown hundreds of times, I never have been shed of the sense of awe I feel about planes and their ability to shrink space and time so quickly. For me, it is less the act of flying itself (that feels boring, tiring, annoying, mostly because of the insane waits and delays and I never seem to get the right amount of sleep the night before) but the visceral contrast it brings. In the morning my life is of a particular tone and rhythm, currently situated in NYC and by evening, I am back at home in PR, surrounded by thick humidity and the loud sound of coquis. Once there, my as currently configured in NYC, has little direct bearing to those around me. Planes don’t just transport, they shift and convert your inner and outer world…
So, if anyone (who got this far) knows of a good social history of the airport, do tell. I would love to read it.
