Mostly offline at home; ext2fs file corruption bug?

[Thomas Schwinge]

Hallo!

Due to some infrastructure changes in my telephone/internet connection at
home -- or rather the Telekom not processing/doing these as
intended... -- I'm cut off of the world at the moment.  (Which is quite
nice on the one hand, but on the other...)  At this very moment, I'm
online via the surf stick (GSM/UMTS) of a friend; we shall see how long
this connection lasts.  :-) I'll try to retrieve emails from time to
time.


Gianluca: I guess we'll chat at another day.


Jérémie, Olaf: w.r.t. GSoC: likewise.


Ludovic: I haven't forgotten your glibc request, but I got
``distracted'':

Yesterday afternoon, I began working on that, and thought: ``Hmm, if I
power up my new Hurd box anyway, I could also let it run some
binutils/GCC tests in parallel.''  Said, and done -- and in the end, I
spent several hours on something that looks like a ext2fs translator file
corruption bug -- or hopefully Git bug, but it unfortunately rather
points into the direction of ext2fs...  :-/

Some (a random handful out of a thousand, roughly) files' content is
getting duplicated: for these files, the pattern generally is that, once
the file regularely ends, its content appears once more.  That is, the
files' content appears once (regularely), and then the same again.  Has
someone ever seen something like that before?


Samuel: I think I know what's going on w.r.t. the GNU/Linux ABI field in
certain .o files: have a look at ELFOSABI_LINUX getting set as soon as
there are symbols with STT_GNU_IFUNC type or STB_GNU_UNIQUE binding in
Git commit 51b2f560ad035dffad3371093f8e5c80608d196c.  Of course, this
would've been wrong already before for IFUNC, but I guess STB_GNU_UNIQUE
is emitted more frequently with modern GCC?  I'll try to continue with
looking at this.


Grüße,
 Thomas
