OpenWRT package mod used : transmission-git

In continuation of this issue regarding my specific case above.

Apart from the errors showing in the log, does transmission actually work? Because line by line:

Sat Jul 23 21:34:29 2022 daemon.err transmission-daemon[23381]: [2022-07-23 14:34:29.647] ERR utils.cc:218 Couldn't read '/data/config/stats.benc': No such file or directory (2) (transmission-3.00/libtransmission/utils.cc:218)

Stats have not been created (and won't be), so not surprising they cannot be read. Should not be a problem.

Sat Jul 23 21:34:29 2022 daemon.err transmission-daemon[23381]: [2022-07-23 14:34:29.647] ERR utils.cc:218 Couldn't read '/data/config/dht.dat': No such file or directory (2) (transmission-3.00/libtransmission/utils.cc:218)

Same for dht.dat.

Sat Jul 23 21:34:29 2022 daemon.err transmission-daemon[23381]: [2022-07-23 14:34:29.647] ERR variant.cc:1136 Couldn't save '/data/config/settings.json': Permission denied (13) (transmission-3.00/libtransmission/variant.cc:1136)

Configuration is rendered from UCI /etc/config/transmission, hence transmission itself cannot and should not save configuration.

Sat Jul 23 21:34:29 2022 daemon.err transmission-daemon[23381]: [2022-07-23 14:34:29.647] ERR variant.cc:1136 Couldn't save '/data/config/bandwidth-groups.json': Permission denied (13) (transmission-3.00/libtransmission/variant.cc:1136)

This has probably been added recently to transmission, I don't know this file and also don't see this error with the 3.00 release of transmission.

Sat Jul 23 21:34:29 2022 daemon.err transmission-daemon[23381]: [2022-07-23 14:34:29.647] ERR watchdir-inotify.cc:180 Couldn't watch '/data/watch': No such file or directory (2) (transmission-3.00/libtransmission/watchdir-inotify.cc:180)

/data/watch indeed doesn't exist. Create it or remove the watchdir option.

Getting the following when downloading :

Permission denied (/data/transmission/done/Test[Test]/Test.mkv)

And the from log(Info) :

And inside incomplete is empty..

Hmm somehow now running transmission-daemon without jail is working! :

#procd_add_jail transmission log
#procd_add_jail_mount "$config_file"
#procd_add_jail_mount_rw "$config_dir/resume"
#procd_add_jail_mount_rw "$config_dir/torrents"

#procd_add_jail_mount_rw "$download_dir"
#[ "$incomplete_dir_enabled" = "1" ] && procd_add_jail_mount_rw "$incomplete_dir"
#[ "$watch_dir_enabled" = "1" ] && procd_add_jail_mount_rw "$watch_dir"
web_home="${web_home:-/usr/share/transmission/public_html}"
[ -d "$web_home" ] && procd_add_jail_mount "$web_home"
[ -f "$ca_bundle_file" ] && procd_add_jail_mount "$ca_bundle_file"
procd_close_instance

Managed to downloaded the test torrent, should I close this?, since it's not an official OpenWRT package?.

Thanks again @dangowrt for the helps and pointers.

@dangowrt What is the correct way to create seccomp for the transmission-daemon?, should I eliminating all ujail related calls in the /etc/init.d/transmission and add ujail before the /usr/bin/transmission-daemon?.

Tried with /etc/init.d/tranmission trace but getting ujail: unable to load dependecies.

Tried with /sbin/utrace /usr/bin/transmission-daemon but only getting a few, how to make utrace sort of 'hooking' into the transmission-daemon process until it ended?.

Currently I have the following seccomp for the transmission-daemon :
