[PR] BUG/MINOR: http-fetch: recognize IPv6 addresses in square brackets in req.hdr_ip()
Dear list! Author: Oto Valek Number of patches: 2 This is an automated relay of the Github pull request: BUG/MINOR: http-fetch: recognize IPv6 addresses in square brackets in req.hdr_ip() Patch title(s): BUG/MINOR: http-fetch: recognize IPv6 addresses in square brackets in req.hdr_ip() REGTEST: added tests covering smp_fetch_hdr_ip() Link: https://github.com/haproxy/haproxy/pull/2063 Edit locally: wget https://github.com/haproxy/haproxy/pull/2063.patch && vi 2063.patch Apply locally: curl https://github.com/haproxy/haproxy/pull/2063.patch | git am - Description: Fixes haproxy/haproxy#2054 To comply with [RFC7239](https://www.rfc-editor.org/rfc/rfc7239.html#section-6.1) and [RFC3986](https://www.rfc-editor.org/rfc/rfc3986.html#section-3.2.2), the `req.hdr_ip()` should recognize IPv6 addresses in square brackets. As the `inet_pton()` call does not support this format, the `smp_fetch_hdr_ip()` function was changed to trim possible `'['` and `']'` before calling `inet_pton()`. New reg test cases were added to cover all 4 branches of smp_fetch_hdr_ip(). Instructions: This github pull request will be closed automatically; patch should be reviewed on the haproxy mailing list (haproxy@formilux.org). Everyone is invited to comment, even the patch's author. Please keep the author and list CCed in replies. Please note that in absence of any response this pull request will be lost.

> In the HAProxy configuration i'm using the FQDN name, and it seems > HAProxy is just using the short hostname. This seems to be true indeed, "localpeer" default value is retrieved thanks to gethostname() in haproxy However, since no obvious changes around "localpeer" handling occurred between 2.4.15 and 2.4.22 it looks like your previous system (ubuntu 18.04) behaved differently and used to return "s017.domain.local" with gethostname() and 'hostname' command (without the -f) (Please note that hostname command relies on uname() internally, and not on gethostname(), but the manual confirms that hostname command without arguments "will print the name of the system as returned by the gethostname(2) function.") Could you confirm? Thanks

I've also rebooted the hosts to rule out other possibly issues. I've found something in the haproxy logs: haproxy[16083]: [WARNING] (16083) : Removing incomplete section 'peers LB' (no peer named 's017'). Maybe it's some sort of hostname/FQDN lookup "issue": # hostname s017 # hostname -f s017.domain.local In the HAProxy configuration i'm using the FQDN name, and it seems HAProxy is just using the short hostname. - Mit freundlichen Grüßen / Best regards Bjoern

Can you bind to those ports with something like nc? nc -l -s 192.168.120.207 -p 1234 Lukas
stick-table replication not working anymore after Version-Upgrade
Hi, i've upgraded from HAProxy 2.4.15 (OS: Ubuntu 18.04) to 2.4.22 (OS: Ubuntu 22.04). Now the stick-table synchronization between peers isn't working anymore. The peers listener is completely not existing (lsof output). HAProxy config: peers LB peer s017.domain.local 192.168.120.207:1234 peer s018.domain.local 192.168.120.208:1234 backend be_redis stick-table type ip size 10 peers LB stick on dst server s021.domain.local 192.168.120.212:6379 maxconn 1000 on-marked-down shutdown-sessions track be_redis_tracking/s021.domain.local server s022.domain.local 192.168.120.213:6379 maxconn 1000 on-marked-down shutdown-sessions track be_redis_tracking/s022.domain.local backup -- Best regards Bjoern
