This can cause Exim to segfault if it was configured to use spf. You can see the complete report at: http://www.gossamer-threads.com/lists/spf/devel/24280?do=post_view_threaded The solution is to simply declare the buflen variable as size_t instead of int. I have created a patch and will try to attach it to the bug report. Reproducible: Always Steps to Reproduce: emerge libspf USE="spf" emerge exim Start Exim and wait for some emails to come by. Actual Results: Look at dmesg, you should see the following: exim[11307]: segfault at 0000000000616000 rip 00002aaaabe25a73 rsp 00007fffffbffea8 error 6 olivier.hill@gmail.com 2005-11-20 20:16:11 0000 Created an attachment (id=73276) Patch for 64 bit safety olivier.hill@gmail.com 2005-11-20 20:19:44 0000 Created an attachment (id=73277) libspf2-1.2.5-r2.ebuild jakub@gentoo.org 2006-08-01 10:03:31 0000 Sending this amd64 way, been sitting here for ages and it concerns mainly them, after all. blubb@gentoo.org 2006-09-27 04:56:22 0000 thanks Olivier, patch is applied in -r2 73276 2005-11-20 20:16 0000 files/patch-libspf2-1.2.5-amd64 patch-libspf2-1.2.5-amd64 text/plain LS0tIHNyYy9saWJzcGYyL3NwZl9pbnRlcnByZXQuYy5vcmlnCTIwMDUtMDItMjEgMjI6NDE6Mjcu MDAwMDAwMDAwIC0wNTAwCisrKyBzcmMvbGlic3BmMi9zcGZfaW50ZXJwcmV0LmMJMjAwNS0xMS0y MCAyMjo1NTowNC4wMDAwMDAwMDAgLTA1MDAKQEAgLTQ5LDcgKzQ5LDcgQEAKIAlTUEZfcmVjb3Jk X3QJKnNwZl9yZWNvcmQ7CiAJU1BGX2VycmNvZGVfdAkgZXJyOwogCWNoYXIJCQkqYnVmOwotCWlu dAkJCQkgYnVmbGVuOworCXNpemVfdAkJCQkgYnVmbGVuOwogCWludAkJCQkgbGVuOwogCiAJU1BG X0FTU0VSVF9OT1ROVUxMKHNwZl9yZXNwb25zZSk7Cg== 73277 2005-11-20 20:19 0000 libspf2-1.2.5-r2.ebuild libspf2-1.2.5-r2.ebuild text/plain IyBDb3B5cmlnaHQgMTk5OS0yMDA1IEdlbnRvbyBGb3VuZGF0aW9uCiMgRGlzdHJpYnV0ZWQgdW5k ZXIgdGhlIHRlcm1zIG9mIHRoZSBHTlUgR2VuZXJhbCBQdWJsaWMgTGljZW5zZSB2MgojICRIZWFk ZXI6IC92YXIvY3Zzcm9vdC9nZW50b28teDg2L21haWwtZmlsdGVyL2xpYnNwZjIvbGlic3BmMi0x LjIuNS1yMS5lYnVpbGQsdiAxLjExIDIwMDUvMTAvMjggMTc6MjQ6MzggZ3VzdGF2b3ogRXhwICQK CmluaGVyaXQgZXV0aWxzCgpERVNDUklQVElPTj0ibGlic3BmMiBpbXBsZW1lbnRzIHRoZSBTZW5k ZXIgUG9saWN5IEZyYW1ld29yaywgYSBwYXJ0IG9mIHRoZSBTUEYvU1JTIHByb3RvY29sIHBhaXIu IgpIT01FUEFHRT0iaHR0cDovL3d3dy5saWJzcGYyLm9yZy8iClNSQ19VUkk9Imh0dHA6Ly93d3cu bGlic3BmMi5vcmcvc3BmL2xpYnNwZjItJHtQVn0udGFyLmd6IgoKTElDRU5TRT0iR1BMLTIiClNM T1Q9IjAiCktFWVdPUkRTPSJhbHBoYSBhbWQ2NCBocHBhIHBwYyB+cHBjNjQgc3BhcmMgeDg2IgpJ VVNFPSIiCgpERVBFTkQ9InZpcnR1YWwvbGliYyIKUkRFUEVORD0iIgoKc3JjX3VucGFjaygpIHsK CXVucGFjayAke0F9CgljZCAke1N9CgllcGF0Y2ggJHtGSUxFU0RJUn0vcGF0Y2gtbGlic3BmMi0x LjIuNS1ub2ludGVybmFsIHx8IGRpZQoJZXBhdGNoICR7RklMRVNESVJ9L3BhdGNoLWxpYnNwZjIt MS4yLjUtYW1kNjQgfHwgZGllCn0KCnNyY19jb21waWxlKCkgewoJZWNvbmYgfHwgZGllICJlY29u ZiBmYWlsZWQiCgllbWFrZSB8fCBkaWUgImVtYWtlIGZhaWxlZCIKfQoKc3JjX2luc3RhbGwoKSB7 CgltYWtlIGluc3RhbGwgREVTVERJUj0ke0R9IHx8IGRpZSAibWFrZSBpbnN0YWxsIGZhaWxlZCIK Cglkb2RvYyBDaGFuZ2Vsb2cgSU5TVEFMTCBSRUFETUUgVE9ETyBkb2NzLyoudHh0IGRvY3MvQVBJ Cn0KCnBrZ19wb3N0aW5zdCgpIHsKCWVpbmZvICIke1B9IHdhcyBzdWNjZXNzZnVsbHkgaW5zdGFs bGVkLiIKCWVpbmZvICJQbGVhc2UgcmVhZCB0aGUgYXNzb2NpYXRlZCBkb2NzIGZvciBoZWxwLiIK CWVpbmZvICJPciB2aXNpdCB0aGUgd2Vic2l0ZSBAICR7SE9NRVBBR0V9IgoJZWNobwoJZXdhcm4g IlRoaXMgcGFja2FnZSBpcyBzdGlsbCBpbiB1bnN0YWJsZS4iCglld2FybiAiUGxlYXNlIHJlcG9y dCBidWdzIHRvIGh0dHA6Ly9idWdzLmdlbnRvby5vcmcvIgoJZXdhcm4gIkhvd2V2ZXIsIHBsZWFz ZSBkbyBhbiBhZHZhbmNlZCBxdWVyeSB0byBzZWFyY2ggZm9yIGJ1Z3MiCglld2FybiAiYmVmb3Jl IHJlcG9ydGluZy4gVGhpcyB3aWxsIGtlZXAgZG93biBvbiBkdXBsaWNhdGVzLiIKfQo=
