Package: wpasupplicant Version: 2:2.9.0-15 Severity: important Tags: patch fixed-upstream
Dear maintainer, Could you consider including the following upstream commit: http://w1.fi/cgit/hostap/commit/?id=c0b88d1 merged on 2020-10-10: P2P: Limit P2P_DEVICE name to appropriate ifname size Otherwise the WPA_IF_P2P_DEVICE cannot be created if the base ifname is long enough. As this is not a netdev device, it is acceptable if the name is not completely unique. As such, simply insert a NUL byte at the appropriate place. Signed-off-by: Benjamin Berg <bb...@redhat.com> or packaging a more recent version of wpa_supplicant master branch in Debian since there was no new tag after the 2.9 version released 16 months ago ? The above commit fixes an important issue impacting Wi-Fi P2P and Wi-Fi Display as raised in these 2 projects as concrete examples: https://gitlab.gnome.org/GNOME/gnome-network-displays/-/issues/70 https://github.com/albfan/miraclecast/issues/285 The result can be seen quite easily with iw, for users who have a long Wi-Fi interface name as it is my case with "wlp109s0". With the current 2:2.9.0-15 wpa_supplicant, the P2P-device interface is missing : $ sudo iw dev phy#0 Interface wlp109s0 ifindex 2 wdev 0x1 addr xx:xx:xx:xx:xx:xx ssid SSID type managed channel 36 (5180 MHz), width: 80 MHz, center1: 5210 MHz txpower 22.00 dBm multicast TXQ: qsz-byt qsz-pkt flows drops marks overlmt hashcol tx-bytes tx-packets 0 0 0 0 0 0 0 0 0 and once the above commit is included, the P2P-device interface shows up properly: $ sudo iw dev phy#0 Unnamed/non-netdev interface wdev 0xd addr xx:xx:xx:xx:xx:xx type P2P-device txpower 0.00 dBm Interface wlp109s0 ifindex 2 wdev 0x1 addr xx:xx:xx:xx:xx:xx ssid SSID type managed channel 36 (5180 MHz), width: 80 MHz, center1: 5210 MHz txpower 22.00 dBm multicast TXQ: qsz-byt qsz-pkt flows drops marks overlmt hashcol tx-bytes tx-packets 0 0 0 0 0 0 0 0 0 Thank you, Jérôme
