O projeto OpenBSD foi fundado por Theo de Raadt em 1995 ap\u00f3s um conflito com desenvolvedores do NetBSD, resultando na revoga\u00e7\u00e3o do seu acesso ao reposit\u00f3rio CVS do NetBSD. Ap\u00f3s isso, Theo de Raadt e um grupo de colaboradores criaram uma nova sistema operacional de c\u00f3digo aberto a partir da \u00e1rvore de c\u00f3digo-fonte do NetBSD, cujos principais objetivos de desenvolvimento s\u00e3o portabilidade (suportando 13 plataformas de hardware), padroniza\u00e7\u00e3o, opera\u00e7\u00e3o correta, seguran\u00e7a proativa e ferramentas criptogr\u00e1ficas integradas. O tamanho da imagem ISO de instala\u00e7\u00e3o completa do sistema b\u00e1sico OpenBSD 7.9 \u00e9 de 762 MB. <\/p>\n<p>Al\u00e9m do pr\u00f3prio sistema operacional, o projeto OpenBSD \u00e9 conhecido por seus componentes, que se tornaram populares em outros sistemas e se destacaram como algumas das solu\u00e7\u00f5es mais seguras e de qualidade. Entre eles: LibreSSL (fork do OpenSSL), OpenSSH, o filtro de pacotes PF, os dem\u00f4nios de roteamento OpenBGPD e OpenOSPFD, o servidor NTP OpenNTPD, o correio <a class=\"wpil_keyword_link\" href=\"https:\/\/prohoster.info\/pt\/server\/\" title=\"servidor\" data-wpil-keyword-link=\"linked\">servidor<\/a> OpenSMTPD, multiplexador de terminal de texto (an\u00e1logo ao GNU screen) tmux, daemon identd com implementa\u00e7\u00e3o do protocolo IDENT, alternativa BSDL para o pacote GNU groff \u2014 mandoc, protocolo para a organiza\u00e7\u00e3o de sistemas tolerantes a falhas CARP (Common Address Redundancy Protocol), servidor http leve, utilit\u00e1rio de sincroniza\u00e7\u00e3o de arquivos OpenRSYNC.<\/p>\n<p>O OpenBSD 7.9 \u00e9 o 60\u00ba lan\u00e7amento do projeto. Principais mudan\u00e7as: <\/p>\n<ul>\n<li class=\"l\"> No planejador de tarefas para arquiteturas amd64 e arm64, foi implementado um mecanismo para gerir o uso de n\u00facleos de CPU com base em seu desempenho. Para excluir certos tipos de n\u00facleos durante a opera\u00e7\u00e3o do planejador, foi proposta a vari\u00e1vel sysctl \"hw.blockcpu\", que aceita os seguintes flags: S para excluir n\u00facleos l\u00f3gicos (SMT), P - n\u00facleos comuns, E - n\u00facleos energeticamente eficientes (20-50% mais lentos) e L - n\u00facleos lentos (os mais lentos). Por padr\u00e3o, o valor \u00e9 SL.\n<li class=\"l\"> Foi implementada a possibilidade de hiberna\u00e7\u00e3o adiada (delayed hibernation) para impedir a descarga total da bateria durante o modo de espera. O mecanismo consiste em inicialmente colocar o sistema em modo de espera, no qual a mem\u00f3ria RAM permanece ativa, e permanece nesse estado pelo tempo definido pela vari\u00e1vel sysctl machdep.hibernatedelay. Ap\u00f3s esse tempo, o sistema \u00e9 despertado e imediatamente colocado em modo de suspens\u00e3o (hiberna\u00e7\u00e3o), onde o conte\u00fado da mem\u00f3ria RAM \u00e9 salvo em um armazenamento permanente.\n<li class=\"l\"> A implementa\u00e7\u00e3o do framework drm (Direct Rendering Manager) e dos drivers gr\u00e1ficos para GPU AMD e Intel est\u00e1 sincronizada com o n\u00facleo Linux 6.18.22 (na vers\u00e3o anterior - 6.12.50).\n<li class=\"l\"> Adicionada a suporte para opera\u00e7\u00e3o como sistema convidado em ambientes de virtualiza\u00e7\u00e3o baseados no Apple Hypervisor. As compila\u00e7\u00f5es do OpenBSD para a arquitetura arm64 podem ser usadas em <a class=\"wpil_keyword_link\" href=\"https:\/\/prohoster.info\/pt\/vps\/abuzoustojchivye-vps\/\" title=\"m\u00e1quinas virtuais\" data-wpil-keyword-link=\"linked\">m\u00e1quinas virtuais<\/a> macOS em hardware com chips ARM Apple Silicon.\n<li class=\"l\"> Adicionado o n\u00facleo m\u00ednimo vmboot, permitindo inicializar o ambiente para uma m\u00e1quina virtual baseada no hipervisor vmd ap\u00f3s a atualiza\u00e7\u00e3o atrav\u00e9s do sysupgrade.\n<li class=\"l\"> Os drivers PCI agora t\u00eam a capacidade de alterar seu estado de consumo de energia, isso foi implementado no driver xhci para entrar em modo de baixo consumo de energia e colocar o controlador USB4 associado em modo de suspens\u00e3o.\n<li class=\"l\"> Adicionada uma implementa\u00e7\u00e3o b\u00e1sica da API de baixo n\u00edvel FUSE, suficiente para compilar e executar o driver lowntfs-3g.\n<li class=\"l\"> Adicionada suporte para Wi-Fi 6 (802.11ax).\n<li class=\"l\"> Expandido o suporte para hardware e adicionados novos drivers para controladores USB4, controladores PCIe Cadence, Qualcomm SC7280, Qualcomm GENI UART, controlador SPI Intel LPSS, modem LTE Quectel EC200A.\n<li class=\"l\"> Em sistemas amd64, foi adicionada a possibilidade de carregar arquivos com o n\u00facleo a partir da parti\u00e7\u00e3o EFI, que pode ser usada para colocar o carregador de inicializa\u00e7\u00e3o e bsd.rd na parti\u00e7\u00e3o EFI para iniciar o instalador.\n<li class=\"l\"> Adicionado a chamada de sistema __pledge_open, permitindo que a libc abra alguns arquivos importantes, como o dispositivo do gerador de n\u00fameros pseudoaleat\u00f3rios e a base de fusos hor\u00e1rios, mesmo quando os mecanismos pledge e unveil isso pro\u00edbem. Os arquivos abertos dessa forma est\u00e3o dispon\u00edveis apenas em modo de leitura, e as fun\u00e7\u00f5es write, chmod, chflags, chown, ftruncate e fdpassing s\u00e3o proibidas para eles.\n<li class=\"l\"> Foi adicionada suporte ao dispositivo de rede veb (Virtual Ethernet Bridge) para VLAN.\n<li class=\"l\"> A configura\u00e7\u00e3o autom\u00e1tica do IPv6 (SLAAC) est\u00e1 habilitada por padr\u00e3o.\n<li class=\"l\"> Atualiza\u00e7\u00f5es do OpenSSH, LibreSSL e OpenBGPD.
