a/etc-15.0-x86_64-17.txz: Rebuilt.

Patched with upstream commit to allow using this icon theme with Xfce. l/fluidsynth-2.2.3-x86_64-1.txz: Upgraded. l/python-charset-normalizer-2.0.5-x86_64-1.txz: Upgraded. l/qca-2.3.4-x86_64-1.txz: Upgraded. n/NetworkManager-1.32.10-x86_64-3.txz: Rebuilt. Switch to dhcp=internal to avoid problems swimming upstream. For those looking for a fix to continue using dhcpcd, a PRIVSEP build variable was added to the SlackBuild, and you may produce a fully NetworkManager compatible dhcpcd package with this command: PRIVSEP=no ./dhcpcd.SlackBuild Privilege separation remains the dhcpcd package default as we don't want to weaken security for those using rc.inet1 along with dhcpcd. Some additional comments about this were added to 00-dhcp-client.conf mentioning this and the workaround of killing dhcpcd manually when resuming with the stock dhcpcd package. n/bind-9.16.21-x86_64-1.txz: Upgraded. Fixed call to rndc-confgen in the install script. Make /etc/rndc.key owned by named:named. Run named as named:named by default (configurable in /etc/default/named). rc.bind: chown /run/named and /var/named to configured user:group. Thanks to Ressy for prompting this cleanup. :) n/curl-7.79.0-x86_64-1.txz: Upgraded. This update fixes security issues: clear the leftovers pointer when sending succeeds. do not ignore --ssl-reqd. reject STARTTLS server response pipelining. For more information, see: https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2021-22945 https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2021-22946 https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2021-22947 (* Security fix *) n/links-2.24-x86_64-1.txz: Upgraded. n/wireguard-tools-1.0.20210914-x86_64-1.txz: Upgraded. x/libinput-1.19.0-x86_64-1.txz: Upgraded. xap/gimp-2.10.28-x86_64-1.txz: Upgraded. isolinux/initrd.img: Rebuilt. kernels/*: Upgraded. usb-and-pxe-installers/usbboot.img: Rebuilt.
