Subject: ubus: don't make uhttpd_plugin symbol constant
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=7352ec423fb99a7970b0765287503abee05a56cd;p=oweals%2Fuhttpd.git

ubus: don't make uhttpd_plugin symbol constant

uhttpd modifies the list_head member of the uhttpd_plugin struct when
loading a plugin, therefore we cannot make it const, otherwise we
trigger a security violation if uhttpd is built with RelRO support.
