--000000000000554ea105747b0b71 Content-Type: text/plain; charset="UTF-8" Greetings ! I have developed a new system call, be it named angel(2), on Linux operating system (this is what I know), which makes a program invulnerable to kill(2) calls, including SIGKILL and SIGSTOP. The uses may involve fork() + angel(), daemon() + angel(), setsid() + angel(), exec*() + angel(). Use the intellectual property I give you, as a gift to the BSD operating system, using 4- 3- 2- BSD licence. That's it, name me in the sources. Thank you, FreeBSD ! You are a great Unix operating system ! --000000000000554ea105747b0b71 Content-Type: text/plain; charset="US-ASCII"; name="rack.01.06.txt" Content-Disposition: attachment; filename="rack.01.06.txt" Content-Transfer-Encoding: base64 Content-ID: <f_jldh95cv1> X-Attachment-Id: f_jldh95cv1 CgkwNi4gU3lzY2FsbHMgaW4gdGhlIGxpbnV4IGtlcm5lbCwgYW5kIGluIHRoZSBnbGliYyBsaWJy YXJ5CgoJV2Ugd3JpdGUgYW5nZWwoKSBzeXN0ZW0gY2FsbCwgb24gYSA0LjE0IGtlcm5lbC4gV2Ug d2FudCBpbW1vcnRhbGl0eQoJZm9yIG91ciBwcm9jZXNzIChTSUdLSUxMIGFuZCBTSUdTVE9QIGln bm9yZWQpLCBhbmQgaWYgd2UgYXJlIGEgZGFlbW9uKCkKCXdlIGNhbiBvYnRhaW4gc3lzdGVtLWxp ZmUtdGltZSBwcm9jZXNzZXMvZGFlbW9ucy4gTm90ZSB0aGF0IHRoZSBhbmdlbCgpCglzeXNjYWxs IGNhbiBiZSB1c2VyIGFsc28gYnkgdXNlci1jb25zY2lvdXMgcHJvY2Vzc2VzLCB3aGljaCByZXR1 cm4gMDsKCgoJSG93IEkndmUgZG9uZSBpdCA6CgkKCTEuIENoYW5nZWQgc3RydWN0IHRhc2tfc3Ry dWN0LCBmb3VuZCBpbi91c3Ivc3JjL2xpbnV4L2luY2x1ZGUvc2NoZWQuaAoJYnkgYWRkaW5nIGEg aW50IHVuaXhfZGVhZGx5X3NpZ25hbHM7IGZpZWxkLiBXZSB3YW50IHRoaXMgdG8gYmUgMCwgYW5k Cgl0byBiZSAxLCBvbmx5IHdoZW4gY2FsbGVkIGJ5IHN5c19hbmdlbCgpID09IGFuZ2VsKCkuCglJ biBpbmNsdWRlL3NjaGVkLmgKCQoJMi4gRm9yIHRoaXMsIHdlIG11c3QgbW9kaWZ5IGRvX2Zvcmso KSAvIF9kb19mb3JrKCksIHNvIHdoZW4gd2Ugb2J0YWluCglwID0gY29weV9wcm9jZXNzKCksIHJp Z2h0IGFmdGVyIGl0IHAtPnVuaXhfZGVhZGx5X3NpZ25hbHMgPSAwOwoJSW4ga2VybmVsL2Zvcmsu YwoKCTMuIFJlbWVtYmVyIGZvciB3aGF0IHdlIGhhdmUgY3JlYXRlZCBzeXNfYW5nZWwoKSA6IGlm IHNvbWVvbmUgc2VuZHMsCgl1c2luZyBraWxsKDIpIHN5c3RlbSBjYWxsLCBTSUdTVE9QIG9yIFNJ R0tJTEwgc2lnbmFsIHRvIG91ciBwcm9jZXNzLAoJaGUgbXVzdCBmYWlsLiBMb29rIGluIGtlcm5l bC9zaWduYWwuYywgdGhlcmUgaXMgYSBmdW5jdGlvbgoJZG9fc2lnYWN0aW9uKCksIGFuZCB3ZSBt b2RpZnkgOgoJCWlmIChpbmZvID09IFNFTkRfU0lHX0ZPUkNFRCAmJiB0LT51bml4X2RlYWRseV9z aWduYWxzID09IDEpCgkJCXJldHVybiAocmV0ID0gMCk7CgoJNC4gSW4ga2VybmVsL3N5cy5jLCBv ciBhbm90aGVyIGZpbGUsIHdlIFNZU0NBTExfREVGSU5FMChhbmdlbCkgewoJCWN1cnJlbnQgLT4g dW5peF9kZWFkbHlfc2lnbmFscyA9IDE7CgkJcmV0dXJuIDA7Cgl9CgoJNS4gSW4gc3lzY2FsbF82 NC50YmwsIHRoZSAzMzMtdGggc3lzdGVtIGNhbGwgZm9yIDMzMi1zeXN0ZW0gY2FsbHMKCW9yaWdp bmFsIDQuMTQuMTEgTGludXgga2VybmVsLCBpcyA6CgkJMzMzCWNvbW1vbgkJYW5nZWwJCXN5c19h bmdlbAoKCTYuIEluIGluY2x1ZGUvbGludXgvc3lzY2FsbHMuaCwgYWRkIHRvIHRoZSBlbmQgb2Yg dGhlIGZpbGUsIHJpZ2h0CgliZWZvcmUgI2VuZGlmLAoJCWFzbWxpbmthZ2UgbG9uZyBzeXNfYW5n ZWwodm9pZCk7CgoJNy4gSW4gdXNlcnNwYWNlLCB0aGUgZm9sbG93aW5nIHRlc3QgcHJvZ3JhbSwg YWdhaW5zdCBTSUdLSUxMID09IDkKCWFuZCBTSUdTVE9QID09IDE5IChhbmQgb3RoZXIgc2lnbmFs cyBJIGd1ZXNzLCBidXQgd2h5IEkgZG8gbm90IGtub3cKCXdoeSk6CgkJI2luY2x1ZGUgPHVuaXN0 ZC5oPgoJCSNpbmNsdWRlIDxzeXMvc3lzY2FsbC5oPgoKCQlpbnQgbWFpbigpCgkJewoJCQlzeXNj YWxsKDMzMyk7CgkJCXNsZWVwKDY2KTsKCQkJcmV0dXJuIDA7CgkJfQoKCUNvbXBpbGUgaXQgOiAk IGdjYyBhbmdlbC5jIC1vIGFuZ2VsCglSdW4gaXQgICAgIDogJCAuL2FuZ2VsICYKICAgICAgICBU ZXN0IGl0ICAgIDogJCBraWxsYWxsIGFuZ2VsCglJdCBleGlzdHMgIDogJCBqb2JzCgkJWzFdKyBS dW5uaW5nIAkJLi9hbmdlbCAmCgoJOC4gQ29uY2x1c2lvbiA6IElUIFdPUktTLgoJOS4gV2hhdCBy ZW1haW5zIHRvIGRvIDogdG8gd3JpdGUgYSB3cmFwcGVyIGluIGdsaWJjLCBhbmQgY29tcGlsZSB0 aGUKCWdsaWJjLCBieSB0aGUgcnVsZXMgb2YgZ2xpYmMsIGFzIHdlCgkxMC4gQ29tcGlsZWQgb3Vy IExpbnV4IGtlcm5lbC4KCgoJd2hpdGV3b2xmLCAyMDE3LzIwMTgKCQoJb3RoZXIgc291cmNlcyA6 IAoJICAgIGh0dHA6Ly9hbGV4YW5kcmlhLWtld2wtdGhpbmdzLmJsb2dzcG90LnJvLzIwMTcvCgkg ICAgMDgvb3BlcmF0aW5nLXN5c3RlbXMtdW5peC1teXRoLWJ5cGFzc2VkLmh0bWwK --000000000000554ea105747b0b71--
