Allow Multiple UDP payloads to be specified per port #1859
This change allows for multiple UDP payloads to be specified per port. When attempting to retry a payload this will allow for alternative payloads to be attempted.
Note: This patch was originally written by Paul Miseiko at Rapid7 (my employer). I'm submitting this upstream with permission and by request. Any errors with the PR are likely mine.
Thanks for this contribution! I think this is a great new feature, and I'm on board with most of the patch. Ignore the Travis CI build failure: I made some intervening changes to payload.cc, but I can manually merge this patch around those, so no worries.
I do have one question or concern, though: why does this change from just returning the pointer from
Please let me know the reasoning behind this part of the change so I can get the feature merged. Thanks!

Closes nmap#2084 * Clarify upper boundary for variable-length numerical fields * Make maximize_fdlimit return rlim_t on appropriate platforms. Closes nmap#2085. Fixes nmap#2079 * Credential object is creds.Account, not brute.Account. See nmap#2086 * Clarify location of the Error object * Use correct default buffer position. Closes nmap#2086 * Minor optimization of url.parse_query() * Output of matched fingerprints in http-default-accounts. Fixes nmap#2077 * Document that --open implies --defeat-rst-ratelimit since 7.40 * SNMP scripts are enabled on non-standard ports.

Closes nmap#2089 * Unify AFP pathname serialization * Correct AFP name extraction from responses. Closes nmap#2091 FPGetFileDirParms and FPEnumerateExt2 could crash due to unpacking from out-of-bounds positions. This latent issue got exposed by converting from bin.unpack to more stringent string.unpack * Clarified parsing of the volume list in AFP FPGetSrvrParms * Add cross references between the 2 whois scripts * Streamline Boolean expressions * Centralize AFP timestamp conversion to string * Fix a word-wrapping issue * Prevent SSH2 KEX confusion.

Fixes nmap#2107 * Be more strict with TCP options parsing, avoid reading off the end of TCP options. See nmap#2107 * Remove nmap-update This feature was never publicly released, and has not been distributed in our binary builds for a couple versions now. It needed to be removed in order to reduce the number of places Nmap looks for data files. See nmap#2051 * If fetchfile didn't find the XSL, use a relative path on all platforms. * Do not search NMAPDATADIR on Windows as it is not defined. See nmap#2051 * Remove an unused variable * Require trailing '/' to match a directory name with --script. See nmap#2051 * Stop using Shellshock in header name. Fixes nmap#1983 * Fix line wrapping * Speed improvement for script afp-ls. Closes nmap#2098 * New option --discovery-ignore-rst. Closes nmap#1616 * Nbase is needed for __attribute__ on Windows * include string_pool in Windows build * Use larger buffer size for socket errors (WSAETIMEDOUT was longer). * Allow multiple UDP payloads per port. Closes nmap#1859 (payloads to be committed later) * New UDP payloads. Closes nmap#1860 * Use ASCII chars for some payload data where it makes sense * Pass error along instead of printing (link error) * OpenSSL 1.1.X renamed libs: libeay32->libcrypto ssleay32->libssl * More OpenSSL DLL name changes * One last libeay32->libcrypto name change * Fix loopback detection on Windows with new Npcap * Add some popular favicon hashes * Update nmap-mac-prefixes * Update nmap-services from IANA * Handle too-short response in s7-info. See nmap#2117 * Remove a todo item that is done (--resolve-all) * Update dated 'class' network terms to CIDR. Closes nmap#2054 * Call superclass's init method from derived class * Use signed value for tcp header offset and option lengths to detect underflow * Correctly check for unsigned subtraction underflow. * Add some missing changelog entries * Tell LGTM to use the correct version of Python (2) * Process new Linux and OpenBSD fingerprints * Only get SSL options if we use them, currently for NO_SSLv2 * Process a few service fingerprint submissions * Add a requested feature * Try to make sure enough data is present before parsing. See nmap#2117 * Replace hyphens in the client SSH banner Hyphen is not allowed in the software version string (RFC 4253, section 4.2) * Update the SSH protocol flow. Closes nmap#1460 Allows the server to start the key exchange before the protocol version exchange (banner exchange) is completed * Silence static analysis warning LGTM points out that since comparison with sizeof(buf) coerces n to unsigned, all negative values become very large values, which are necessarily larger than sizeof(buf), so the test is redundant. We still want the test in our code to be explicit that we are checking for it, so reordering the comparisons should silence the warning. A good optimizing compiler should be able to combine the two conditions anyway. See github/codeql#4249 * Be explicit about truncating division (timeout is in whole milliseconds) * Improve docs on -Pn and host discovery "Host discovery" is the preferred term over "ping scan" because of confusion with ICMP Echo Request, a.k.a. "ping" as used by the "ping" utility. Warn when users use -Pn because it has negative impact on scan times since ultrascan timing parameters fall back to slow initial defaults. * Fix a config issue with LGTM (libverbs not linked in libpcap) * Update IPv6 classifier based on new submissions through 2020-09-14 * Fix a meaningless error message when parsing IPv6 extension headers. * Allow %F date format to mean YYYY-mm-dd like GNU date * Remove duplicate test conditionals already tested in enclosing block * Properly handle pcap reads in iocp engine. Fixes nmap#2126 Still has an odd code smell, but this fixes my test case with Nping. * Add missing prototype * Make IOCP the default Nsock engine on Windows. See nmap#2126 * Update macosx build to OpenSSL 1.1.1h, use jhbuild for all build steps * Default rule base for script mysql-audit. See nmap#2125 * Avoid masked use of date before 1/1/1970 UTC. Fixes nmap#2136, closes nmap#2137 * Fix a CHANGELOG typo * Reintegrate Nmap 7.90 release branch * Bump version and regen docs for 7.90SVN post-release * Only warn about protocol specs in port list with -p. Fixes nmap#2135 * Handle a weird IOCP error for UDP sockets.
