If you just change the bytes[16384] to bytes[32768] at the beginning of the oncp_connect() function in oncp.c does it work? yes, a little bit tricky to build, but it works. Thanks for testing. I'll do that in the upcoming 8.04 release. I'd quite like to know what's in that huge config packet though. At the beginning of the parse_conf_pkt() function there is a length check followed by a call to dump_buf_hex() to dump the whole packet. Please could you make it dump the packet unconditionally (just cut and paste that line under the closing curly brace } of the 'if (kmpend > pktlen) {' block) and mail it to dwmw2 please. I'll work out if 32768 is sane or if we should be going higher or even making it dynamic. I have committed a fix. I'll do an OpenConnect 8.04 release fairly soon and ship updates to Fedora. In the meantime, it should shortly be built in the COPR at https://copr.fedorainfracloud.org/coprs/dwmw2/openconnect/ This message is a reminder that Fedora 30 is nearing its end of life. Fedora will stop maintaining and issuing updates for Fedora 30 on 2020-05-26. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a Fedora 'version' of '30'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 30 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. I've testes David change. It works on F30, but also in all releases where openconnect is >=8.4. Root cause for bug is related to proxy setup info sent over the VPN connection in Corporate VPN setup. I think that bug can be closed and version changed by David could be released. I don't know which is the correct process to complete bug reporting and closing. Apologize for this. Thanks for reminder. Version >=8.04 Fedora 30 changed to end-of-life (EOL) status on 2020-05-26. Fedora 30 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. If you are unable to reopen this bug, please file a new report against the current release. If you experience problems, please add a comment to this bug. Thank you for reporting this bug and we are sorry it could not be fixed. |
