Dezvoltatorii bibliotecii criptografice wolfSSL dezvolt\u0103 stiva TCP\/IP wolfIP, optimizat\u0103 pentru utilizarea pe dispozitive \u00eencorporate cu resurse limitate, precum \u0219i pentru sisteme care func\u021bioneaz\u0103 \u00een timp real \u0219i solu\u021bii care necesit\u0103 fiabilitate crescut\u0103 (Safety-Critical). Pentru un consum de resurse previzibil, wolfIP nu folose\u0219te alocare dinamic\u0103 a memoriei - toate bufferele \u0219i tabelele de socket-uri au dimensiuni fixe \u0219i sunt configurate \u00een etapa de compilare. Codul proiectului este scris \u00een limbajul C \u0219i este distribuit sub licen\u021ba GPLv3. <\/p>\n
Proiectul poate fi utilizat ca un stiv\u0103 TCP\/IP func\u021bional\u0103 \u00een spa\u021biul utilizatorului, care \u00eenlocuie\u0219te stiva de re\u021bea a Linux, FreeBSD \u0219i macOS, precum \u0219i fiind potrivit pentru utilizarea \u00een sisteme integrate bazate pe FreeRTOS, SafeRTOS, Zephyr, Azure RTOS ThreadX, NuttX, RTEMS, VxWorks \u0219i QNX. \u00cen plus, pe baza wolfIP pot fi create aplica\u021bii de re\u021bea autonome, care ruleaz\u0103 pe hardware (bare-metal). \u00cempreun\u0103 cu biblioteca wolfSSL, se ofer\u0103 suport pentru TLS 1.3, ceea ce permite crearea de sisteme integrate compacte, care suport\u0103 HTTPS. <\/p>\n
Caracteristici principale ale wolfIP: <\/p>\n
Din limit\u0103rile wolfIP se men\u021bioneaz\u0103 c\u0103 poate fi utilizat doar ca nod final, capabil s\u0103 primeasc\u0103 \u0219i s\u0103 stabileasc\u0103 conexiuni, dar f\u0103r\u0103 a suporta rutarea traficului \u00eentre interfe\u021bele de re\u021bea. <\/p>\n
De asemenea, se remarc\u0103 dezvoltarea activ\u0103 de c\u0103tre un angajat Red Hat a unui stiv TCP\/IP similar, numit passt, care func\u021bioneaz\u0103 \u00een spa\u021biul utilizatorului \u0219i nu folose\u0219te alocarea dinamic\u0103 a memoriei. Proiectul passt este dezvoltat pentru a organiza un canal de comunica\u021bie \u00eentre mediu gazd\u0103 \u0219i sistemele oaspete \u00een QEMU ca o \u00eenlocuire mai sigur\u0103 pentru libslirp. Codul passt este scris \u00een C, are aproximativ 5000 de linii \u0219i este distribuit sub licen\u021ba GPLv2+. <\/p>\n
Printre caracteristicilepasst se num\u0103r\u0103: suportul IPv6<\/a> pe l\u00e2ng\u0103 IPv4, optimiz\u0103ri bazate pe instruc\u021biuni AVX2, protec\u021bie \u00eempotriva synflood, suport

tuturor apelurilor de sistem neutilizate, suport NAT, posibilitatea utiliz\u0103rii ca \u00eenlocuire transparent\u0103 a slirp4netns.
