This converts the TravisCI build to a Github Action. Similar to Travis, we compile and run the script that checks that all options are defined in the manfile. The action runs inside the new `zmap/builder` container, which is defined in `\\container\builder.dockerfile`, and is (manually) published to Dockerhub. This action runs considerably faster than Travis (completes in less than one minute). zmap#660
Update gitignore to properly ignore zblocklist and remove miscommited binary Co-authored-by: David Adrian <davidcadrian@gmail.com>
Some probes may include additional data in probe packets like timestamps, TTL, etc. It may be desirable to include additional information into validation input besides src and dst IPs. This patch adds additional validation generator function which allows to fill all fields of the aes_input array, so that probe could use it to include additional information to sourch of the validation. zmap#650 Signed-off-by: Alexander Zubkov <green@qrator.net> Co-authored-by: Zakir Durumeric <zakird@gmail.com>
This makes a few more functions operate on const char * so that we can remove casts in zmap.c.
* remove unused probe modules fields and use consistent help file capitalization * Sane default behavior + more helpful error messages * info that's really not needed * fixing man file * Update zmap.c
* Ensure all probe modules set *buf_len Probe modules with dynamic output already needed to set `*buf_len` during calls to `make_packet`. Not all probe modules did this. Some opted to update the value of `probe_module.packet_length`. This is not safe in a multithreaded invocation. This commit forces all probe modules to update `*buf_len`, and replaces the packet_length parameter with a max_packet_length, which is used for bandwidth rate calculation as an upper bound. It is unclear if the rate calculation works currently, but at least it's getting consistent input now. * wip * split templated from static udp * fix templating * remove debug logs
The send rate variable is only used when calculating sleep times for "slow" rates. It was not correctly accounting for multiple probes. Adding this in fixes the percent calculation.
* Set MSS to default Linux MSS in synscan modules For both synscan and synackscan, set MSS to 1450. This is the default Linux MSS, and the option is required to be set for certain hosts to respond. Fixes zmap#601 * set_tcp_options to set_mss_option
* move udp_unreach strings to icmp_unreach_strings since that's what they are. Also move to using PACKET_(IN)VALID instead of random constants for my sanity * udp module uses abstracted out ICMP validation logic * udp and tcp use the same style of packet validation * starting to look like we have reasonable validation for expected protocol as well as ICMP in most places * more fixups for reasonable packet validation * tcp synack scan * always more * and we're compiling again * chugging along. * fix formatting * compile, get rid of warnings * standardize UNUSED and PRINT_PACKET_SEP * successful build * TCP looks sane * bacnet looks sane * fieldsets govern that the right fields are added at the right times * Trying to start fixing DNS * tcp fixes now that validation uncovers problems * dns and udp work * i * ntp works * starting to fix tcp_synack_scan * synack scan * moving remote changes here * some small fixes * icmp * no idea on comment * more sane formatting * inline correct * Removign nonsensical command * char -> uint8_t * removing cisco to be an example Co-authored-by: Alex Holland <ajholland77@yahoo.com>
In the current code it is not possible to pass `--probe-args=hex:..` to the `udp` probe module. The following error message is displayed: ``` udp: unknown UDP probe specification (expected file:/path or text:STRING or hex:01020304 or template:/path or template-fields) ```
Fixes zmap#677 Co-authored-by: ycaibb <ycaibb@gmail.com>
The function is not called anywhere. The module's make_packet uses `udp_make_packet`. The type of `ntp_make_packet` is also not compatible with `probe_make_packet_cb` any longer. For example the `size_t *buf_len` argument is missing. zmap#681
* Use multi-stage building to reduce image size * Add GitHub Action to publish image automatically on GitHub container registry zmap#688
