I've reported this as bug 171835 in RedHat's bugzilla system. Redhat problem, not yours or lkml's. 2) It turns out that the issue in 171835 only bites if other things have already gone bad. It turns out that a patch in -rc5-mm1 causes the indigestion. clean-crypto-sha1c-up-a-bit.patch gives the modsign patches indigestion. I'm not sure why yet, or who's code is busticated. All I've verified for sure is that modsign allocates a 20-byte buffer, and with the cleanup patch applied, I'm seeing different values in buffer[12..19]. It's 4AM, and I'm not going to chase this any further until evening. *yawn* ;) --==_Exmh_1130400431_2704P Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.2 (GNU/Linux) Comment: Exmh version 2.5 07/13/2001 iD8DBQFDYIqvcC3lWbTT17ARAn/TAKDFqTzKkNCiiwPdBGO1Weg7Nbau5QCgib8z 1NriT9IjGLdiljsMKQELTQs= =aNeI -----END PGP SIGNATURE----- --==_Exmh_1130400431_2704P-- - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
