Comment 3 for bug 524919

I don't believe this is a regression caused by the fix in bug #390833. The only change that fix made was to the st_blocks field of the stat struct.

The problem that Loïc is seeing is that return value of readlink() and st_size don't match. As far as I can tell, that has always been the case since the inception of the encrypted filename feature in eCryptfs. The reason is that when we create a symbolic link, we have to store the encrypted version of the target path in the sym link file. However, when readlink() is called we decrypt that path and return the unencrypted path, resulting in a difference in readlink()'s return value and the reported st_size of the sym link file.

Loïc, have you been able to successfully use dpkg inside your eCryptfs partition (with encrypted filenames enabled) before? My guess is that either no one has tried this before or the 'assert(r == stab.st_size);' is relatively new.
